A telephoto camera module refers to a camera module with a long focal length, which can clearly capture subjects at a long distance. However, due to its relatively long focal length, the telephoto camera module requires a long total optical lens length (TTL), making the size of the telephoto camera module relatively large. Moreover, the camera module usually needs to perform optical focus and/or optical image stabilization functions, which requires the size of the telephoto camera module to be larger, making it unsuitable for assembly in small mobile devices.

The present application provides a solution to the above-mentioned problem, which miniaturizes the camera module and makes the camera module suitable for being installed in a small mobile device.

FIG. 1 to FIG. 15 show a camera module 1 according to some embodiments of the present application, wherein the camera module 1 includes an optical lens 10, a light deflection element 30, a photosensitive component 40, and a driving device 60. The light deflection element 30 is disposed between the optical lens 10 and the photosensitive component 40, so that the light incident on the optical lens 10 is reflected at least once in the light deflection element 30 before reaching the photosensitive component 40. The light deflection element 30 folds the light emitted from the optical lens 10 and guides it to the photosensitive component 40, thereby imaging through the photosensitive component 40 to obtain image information. It is worth mentioning that the light deflection element 30 is in the shape of a long strip, so that the light can be reflected multiple times in the light deflection element 30, thereby folding the light path multiple times. In the present application, the position of one or more components among the optical lens 10, the light deflection element 30 or the photosensitive component 40 in the camera module 1 can be adjusted to achieve the optical focus and/or optical image stabilization function of the camera module 1. For example, the driving device 60 can be configured to drive one or more components among the optical lens 10, the light deflection element 30 or the photosensitive component 40 to move.

The optical lens 10 has an optical axis, and the light incident along the optical axis direction is reflected at least once in the light deflection element 30, that is, the light is deflected from propagating along the optical axis direction to propagating in another direction roughly orthogonal to the optical axis, and finally emitted along the optical axis direction to reach the photosensitive component 40. For the convenience of description, a rectangular coordinate system is established, the Z axis approaches the optical axis direction of the optical lens 10 or the direction parallel to the optical axis of the optical lens 10, the Z axis direction is perpendicular to the plane where the X axis direction and the Y axis direction are located, the X axis direction and the Y axis direction are perpendicular to each other, the XOY plane where the X axis direction and the Y axis direction are located is also called the plane where the horizontal direction is located, the X axis direction is the length direction of the camera module 1, the Y axis direction is the width direction of the camera module 1, and the Z axis direction is the height direction of the camera module 1. It should be understood that in the embodiment of the present application, the optical axis of the optical lens 10 is also used as the optical axis of the camera module 1.

As shown in Figures 1 to 2B, the light deflection element 30 includes a plurality of reflective surfaces. The light emitted by the optical lens 10 is reflected multiple times on the plurality of reflective surfaces of the light deflection element 30. After being emitted by the light deflection element 30, the light reaches the photosensitive component 40. The photosensitive component 40 and the optical lens 10 are arranged on the same side of the light deflection element 30. Therefore, the height dimension of the camera module 1 only needs to consider the sum of the height dimension of one of the photosensitive component 40 and the optical lens 10 and the height dimension of the light deflection element 30, without having to simultaneously superimpose the heights of the optical lens 10, the light deflection element 30 and the photosensitive component 40. In this way, the height dimension of the camera module 1 can be reduced. In a specific example, the optical lens 10 and the light deflecting element 30 form an "L"-shaped structure, and the photosensitive component 40 is arranged in the corner space formed by the optical lens 10 and the light deflecting element 30. The height dimension of the optical lens 10 is greater than the height dimension of the photosensitive component 40, and the top surface of the optical lens 10 is higher than the top surface of the photosensitive component 40. In this way, the photosensitive component 40 does not affect the height of the camera module 1, wherein the top surface of the optical lens 10 and the top surface of the photosensitive component 40 respectively refer to the side thereof away from the light deflecting element 30.

The optical lens 10 includes a lens barrel 12 and at least one optical lens 11 accommodated in the lens barrel 12. The optical lens 10 collects light from the subject and transmits it to the light deflection element 30. The optical lens 10 has an optical axis, and the optical axis of the optical lens 10 is perpendicular to the light deflection element 30. In a specific example, as shown in FIG. 2A and FIG. 2B, the optical lens 10 includes three optical lenses 11, namely, a first lens L1, a second lens L2, and a third lens L3, which are arranged along the incident direction of the light. The first lens L1, the second lens L2, and the third lens L3 are fixed to the lens barrel 12, so that the distance between the three optical lenses 11 is maintained by the lens barrel 12. It is worth mentioning that in one embodiment of the present application, the diameter of the inner wall of the lens barrel 12 decreases along the incident direction of the light, so that the diameter of at least one optical lens 11 in the lens barrel 12 gradually decreases along the incident direction of the light. Therefore, in the assembly of the optical lens 10, at least one optical lens 11 is installed into the lens barrel 12 according to the diameter from small to large. For example, the third lens L3 may be installed in the lens barrel 12 first, then the second lens L2 may be installed in the lens barrel 12, and finally the first lens L1 may be installed in the lens barrel 12, wherein glue and/or a pressure ring may be provided between the peripheral side of the first lens L1 and the inner wall of the lens barrel 12 so that the three optical lenses 11 are fixed in the lens barrel 12.

In one embodiment of the present application, the camera module 1 further includes a compensation lens group 20, which can be arranged between the optical lens 10 and the light deflection element 30, and the compensation lens group 20 can further modulate the light emitted from the light deflection element 30. For example, the light emitted from the light deflection element 30 can be further converged by the compensation lens 21 to reduce the back focus, thereby achieving the purpose of reducing the size of the camera module 1. In a specific example, the compensation lens group 20 includes a compensation lens 21, which is fixed to the light-emitting side of the optical lens 10 by glue bonding. For example, the compensation lens 21 is fixed to the bottom side of the lens barrel 12 by glue bonding (the bottom side of the lens barrel 12 refers to the side of the lens barrel 12 close to the light deflection element 30). Since the compensation lens 21 is not fixed in the lens barrel 12, the diameter of the compensation lens 21 can be larger than one of the at least one optical lens 11 of the optical lens 10. Therefore, the compensation lens 21 has a large degree of design freedom.

The photosensitive component 40 includes a chip circuit board 42, a photosensitive chip 41 electrically connected to the chip circuit board 42, and at least one electronic component 43, wherein the photosensitive surface of the photosensitive chip 41 faces the light deflection element 30 to receive the light emitted from the light deflection element 30. In a specific example, the photosensitive chip 41 is fixed to the side of the chip circuit board 42 facing the light deflection element 30. The at least one electronic component 43 can be implemented as a passive electronic device such as a capacitor or a resistor or an active electronic device such as a diode or a memory chip, and the at least one electronic component 43 can be arranged on the side of the chip circuit board 42 facing the light deflection element 30 or on the other side away from the light deflection element 30.

Furthermore, in some embodiments of the present application, the camera module 1 further includes a filter component 50, which is disposed on the optical path of the light, and the camera module 1 can filter out unnecessary stray light (such as infrared light) through the filter component 50. In one embodiment of the present application, the filter component 50 is disposed between the light turning element 30 and the photosensitive component 40. For example, in a specific example, the filter component 50 includes a filter element 51 and a filter element bracket 52 for supporting the filter element 51. The filter element 51 is supported on the filter element bracket 52 by, for example, gluing. The two sides of the filter element bracket 52 are respectively fixed to the chip circuit board 42, so that the filter component 50 is disposed between the light turning element 30 and the photosensitive chip 41. In other embodiments of the present application, the filter component 50 can be disposed in the light deflection element 30 and/or the optical lens 10. For example, the filter component 50 can be implemented as a layer of filter film, which is attached to a surface of the light deflection element 30, or the filter film is attached to the surface of at least one optical lens 11 of the optical lens 10, thereby achieving the function of filtering out infrared light.

In the present application, as shown in FIGS. 2A to 3B , the light deflection element 30 has a plurality of reflective surfaces so that the light entering the light deflection element 30 can be reflected multiple times, which can effectively increase the optical TTL, making the camera module 1 suitable for capturing objects at a long distance and providing high-quality images of the objects at a long distance. TTL refers to the distance on the optical axis between the front vertex of the light incident side (facing the object) of the optical lens 10 of the camera module 1 and the image plane at the photosensitive component 40.

Under normal circumstances, the increase of TTL will increase the size of the camera module 1, making it unsuitable for integration in small mobile devices. In one embodiment of the present application, the light deflection element 30 extends in the horizontal direction, that is, the length of the light deflection element 30 in the horizontal direction is greater than its height or thickness in the height direction. When the light is reflected multiple times in the light deflection element 30, the light deflection element 30 can maintain a lower height or thickness, thereby avoiding an increase in the height of the camera module 1. In other words, the length of the light deflection element 30 extending in the horizontal direction is greater than its height extending in the height direction, so as to reduce the height of the camera module 1 while maintaining its effectiveness, thereby meeting the demand for miniaturization of the camera module 1.

In one embodiment of the present application, the number of times the light is reflected in the light deflection element 30 is an odd number, the photosensitive component 40 and the optical lens 10 are centrally arranged on the same side of the light deflection element 30, and the light passing through the optical lens 10 is reflected in the light deflection element 30 for an odd number of times before being emitted to reach the photosensitive component 40. In another embodiment of the present application, the number of times the light is reflected in the light deflection element 30 is an even number, the photosensitive component 40 and the optical lens 10 are respectively arranged on the opposite sides of the light deflection element 30, and the light passing through the optical lens 10 is reflected in the light deflection element 30 for an even number of times before being emitted to reach the photosensitive component 40.

Specifically, in one embodiment of the present application, the light deflecting element 30 includes at least four surfaces, at least three of the at least four surfaces are reflective surfaces, and the light is reflected on the at least three reflective surfaces in the light deflecting element 30. For example, the light deflecting element 30 includes a trapezoidal prism, and the cross-section of the light deflecting element 30 is a trapezoid. When the light deflecting element 30 includes three reflective surfaces, the light is reflected three times in the light deflecting element 30; when the light deflecting element 30 includes four reflective surfaces, the light is reflected five times or four times in the light deflecting element 30, which will be described in detail later in the present application. Of course, in other embodiments of the present application, the light deflecting element 30 may include prisms of other shapes. Mirrors, such as triangular prisms, pentagonal prisms, hexagonal prisms, etc., can still provide the above-mentioned light turning functions and design benefits, and the present application is not limited to this.

As shown in FIG. 2A and FIG. 2B , in one embodiment of the present application, the light deflection element 30 is implemented as a trapezoidal prism, and the light deflection element 30 includes four surfaces, for example, a first surface 31, a second surface 32, a third surface 33, and a fourth surface 34. The plane where the first surface 31 is located is parallel to the plane where the third surface 33 is located, the length of the third surface 33 is less than the length of the first surface 31, and the plane where the second surface 32 is located intersects with the plane where the fourth surface 34 is located. Among them, at least three of the four surfaces of the light deflection element 30 have a reflective function, for example, the first surface 31, the second surface 32, and the fourth surface 34 are reflective surfaces, which have a reflective function and can reflect light; or, the first surface 31, the second surface 32, the third surface 33, and the fourth surface 34 are reflective surfaces, which have a reflective function and can reflect light.

In a specific example, the angle at which the second surface 32 intersects with the first surface 31 is an acute angle, the angle at which the fourth surface 34 intersects with the first surface 31 is an acute angle, the angle at which the second surface 32 intersects with the third surface 33 is an obtuse angle, and the angle at which the fourth surface 34 intersects with the third surface 33 is an obtuse angle. Among them, the angle at which the second surface 32 intersects with the first surface 31 may be in the range of 25° and 35°, and the angle at which the fourth surface 34 intersects with the first surface 31 may be in the range of 25° and 35°. It should be understood that the angles between the various surfaces of the light deflection element 30 can control the reflection angle of light when it is reflected in the light deflection element 30, so as to realize the function of the light deflection element 30 to reflect the light multiple times.

Furthermore, the light deflection element 30 is an isosceles trapezoidal prism, that is, as shown in the cross-sectional view of the trapezoidal prism, the lengths of the second surface 32 and the fourth surface 34 are equal, and the second surface 32 and the fourth surface 34 are axially symmetrical. Among them, the angle between the second surface 32 and the first surface 31 is equal to the angle between the fourth surface 34 and the first surface 31, and the angle between the second surface 32 and the third surface 33 is equal to the angle between the fourth surface 34 and the third surface 33. It should be understood that since the light will be reflected multiple times in the light deflection element 30, a slight change in the angle between the second surface 32 and the fourth surface 34 will affect the reflection of the light. When the second surface 32 and the fourth surface 34 are symmetrically arranged, the incident light can be emitted from the light deflection element 30 as much as possible after multiple reflections to reach the photosensitive component 40, thereby reducing the loss of light. In a specific example, the optical axis of the incident light is axially symmetrical in the optical path of the light deflection element 30.

In one embodiment of the present application, the second surface 32, the fourth surface 34 and/or the third surface 33 of the light deflection element 30 may be provided with a reflective coating, or a reflector may be provided, so that light can be reflected on the second surface 32, the fourth surface 34 and/or the third surface 33. For example, in a specific example of the present application, the reflective coating may include a mirror coating based on a thin metal layer, a film with a white inner surface, etc. Further, at least a portion of the first surface 31 of the light deflection element 30 is provided with the reflective coating, and at least a portion of the first surface 31 is not provided with the reflective coating, so that the first surface 31 can transmit light or allow light to pass through the first surface 31. Further, the first surface 31 can also reflect light under the phenomenon of total internal reflection.

It should be understood that when the incident angle of the light is close to or greater than a certain limiting angle (called the critical angle), total internal reflection may occur. The incident angle refers to the angle between the light incident on the surface and the line perpendicular to the surface at the incident point (called the normal line). Therefore, when the incident angle of the light is less than the critical angle, the first surface 31 of the light deflection element 30 allows the light to pass through; when the incident angle of the light is close to or greater than the critical angle, the first surface 31 of the light deflection element 30 may reflect the light at the corresponding surface.

Specifically, in one embodiment of the present application, the first surface 31 includes a light entrance area 311, a light exit area 312, and a reflection area 313 disposed between the light entrance area 311 and the light exit area 312, wherein the light entrance area 311 and the light exit area 312 are not provided with a reflection coating, so that light can enter the light turning element 30 from the light entrance area 311 and exit the light turning element 30 from the light exit area 312. The reflection area 313 is provided with a reflection coating, so that light is reflected when passing through the reflection area 313.

In one example, the size of the light entrance area 311 is equal to the size of the light exit area 312, and the size of the reflection area 313 is not less than the size of the light entrance area 311 or the light exit area 312, so that the light entering the light deflection element 30 from the light entrance area 311 can be reflected and then emitted from the light exit area 312 to reach the photosensitive component 40, thereby avoiding the loss of light and reducing the generation of stray light. In a specific example of the present application, the size of the light entrance area 311 is equal to the size of the reflection area 313, which is equal to the size of the light exit area 312, so that the multiple reflections of the light deflection element 30 have a better effect, avoiding the loss of light and reducing the generation of stray light.

Furthermore, the light entry area 311 and the light exit area 312 are both arranged on the first surface 31, that is, the light entry and exit of the camera module 1 are both located on the same side of the light deflection element 30. In this way, the optical lens 10 and the photosensitive component 40 are concentrated on the same side of the light deflection element 30. In this way, the height of the camera module 1 is only determined by the sum of the height of the optical lens 10 or the photosensitive component 40 and the height of the light deflection element 30, which is beneficial to reducing the height of the camera module 1.

In one embodiment of the present application, as shown in FIG2A , the light deflecting element 30 can reflect the light in the light deflecting element 30 an odd number of times to guide the light from the optical lens 10 to pass through the light deflecting element 30 to reach the photosensitive component 40. When the light is reflected three times in the light deflecting element 30, the light passes through the light entrance area 311 of the first surface 31 to enter the light deflecting element 30; at least some of the light passing through the light entrance area 311 of the first surface 31 is reflected at the second surface 32; at least some of the light reflected from the second surface 32 is reflected at the reflection area 313 of the first surface 31; at least some of the light reflected from the reflection area 313 of the first surface 31 is reflected at the fourth surface 34; so that the light passes through the light exit area 312 of the first surface 31 to reach the photosensitive component 40.

In another embodiment of the present application, as shown in Figure 2B, when the light is reflected five times in the light deflection element 30, the light passes through the light entrance area 311 of the first surface 31 and enters the light deflection element 30; at least some of the light passing through the light entrance area 311 of the first surface 31 is reflected at the second surface 32; at least some of the light reflected from the second surface 32 is reflected at the reflection area 313 of the first surface 31; at least some of the light reflected from the reflection area 313 of the first surface 31 is reflected at the third surface 33; at least some of the light reflected from the third surface 33 is reflected at the light exit area 312 of the first surface 31; and, at least some of the light reflected from the light exit area 312 of the first surface 31 is reflected at the fourth surface 34, so that the light passes through the light exit area 312 of the first surface 31 and reaches the photosensitive component 40.

It should be understood that the light from the optical lens 10 can enter the light redirecting element 30 through the light incident area 311 of the first surface 31 and undergo an odd number of reflections in the light redirecting element 30. At least some of the light can reach the second surface 32 and then be reflected at the second surface 32, and at least some of the light reflected from the second surface 32 can reach the reflection area 313 or the light incident area 311 of the first surface 31. When light reaches the reflection area 313 of the first surface 31, it is reflected at the reflection area 313 of the first surface 31, and at least some of the light reflected from the reflection area 313 of the first surface 31 can reach the third surface 33 or the fourth surface 34, and be reflected at the third surface 33 or the fourth surface 34; when light reaches the light entrance area 311 of the first surface 31, when the incident angle of the light is close to or greater than the critical angle of the light turning element 30, the light can be reflected at the light entrance area 311 of the first surface 31 under total internal reflection, and at least some of the light reflected from the light entrance area 311 of the first surface 31 can reach the third surface 33 or the fourth surface 34, and be reflected at the third surface 33 or the fourth surface 34.

If at least some of the light reflected from the first surface 31 reaches the fourth surface 34, and is finally reflected at the fourth surface 34, it leaves the light deflection element 30 to reach the photosensitive component 40. As shown in FIG2A , in this embodiment, the light is reflected three times in the light deflection element 30, which can effectively increase the focal length between the optical lens 10 and the photosensitive component 40, that is, the optical TTL of the camera module 1 can be effectively increased, so that the camera module 1 is suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

If at least some of the light reflected from the first surface 31 reaches the third surface 33, then at least some of the light reflected from the third surface 33 can reach the light exit area 312 of the first surface 31. When the incident angle of the light is close to or greater than the critical angle of the light deflection element 30, the light can be reflected at the light exit area 312 of the first surface 31 under total internal reflection. At least some of the light reflected from the light exit area 312 of the first surface 31 can reach the fourth surface 34, and finally be reflected at the fourth surface 34, leaving the light deflection element 30 to reach the photosensitive component 40. As shown in FIG2B , in this embodiment, the light is reflected five times in the light deflection element 30, which can effectively increase the focal length between the optical lens 10 and the photosensitive component 40, that is, the optical TTL of the camera module 1 can be effectively increased, so that the camera module 1 is suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

As shown in FIG. 2C , in another embodiment of the present application, the light deflection element 30 is implemented as a parallelogram prism, and the light deflection element 30 includes four surfaces, for example, a first surface 31, a second surface 32, a third surface 33, and a fourth surface 34. The plane where the first surface 31 is located is parallel to the plane where the third surface 33 is located, and the plane where the second surface 32 is located is parallel to the plane where the fourth surface 34 is located. The four surfaces of the light deflection element 30 have a reflective function, for example, the first surface 31, the second surface 32, the third surface 33, and the fourth surface 34 are reflective surfaces that can reflect light.

In this embodiment, the light is reflected four times in the light deflection element 30, and the photosensitive component 40 and the optical lens 10 are respectively arranged on the opposite sides of the light deflection element 30. The light passing through the optical lens 10 is reflected four times in the light deflection element 30 and then emitted to the photosensitive component 40. For example, the optical lens 10 is arranged on one side of the first surface 31, and the photosensitive component 40 is arranged on one side of the third surface 33.

Continuing to refer to FIG. 2C , the light deflecting element 30 can reflect the light in the light deflecting element 30 an even number of times to guide the light from the optical lens 10 to pass through the light deflecting element 30 to reach the photosensitive component 40. When the light is reflected four times in the light deflecting element 30, the light passes through the light entrance area 311 of the first surface 31 to enter the light deflecting element 30; at least some of the light passing through the light entrance area 311 of the first surface 31 is reflected at the second surface 32; at least some of the light reflected from the second surface 32 is reflected at the reflection area 313 of the first surface 31; at least some of the light reflected from the reflection area 313 of the first surface 31 is reflected at the third surface 33; at least some of the light reflected from the third surface 33 is reflected at the fourth surface 34, so that the light passes through the light exit area 312 of the first surface 31 to reach the photosensitive component 40.

In one embodiment of the present application, the light deflection element 30 can be implemented as an integrated prism, as shown in FIG. 2A , FIG. 2B and FIG. 2C , and the integrated prism is a trapezoidal prism. In another embodiment of the present application, the light deflection element 30 can also be implemented as a split prism 36, that is, the light deflection element 30 can be formed by combining multiple prisms. For example, the split prism 36 includes at least two prisms: a first prism 361 and a second prism 362, wherein, in a specific example of the present application, as shown in FIG. 3A , the first prism 361 is a parallelogram prism, and the second prism 362 is a triangular prism, and the first prism 361 and the second prism 362 are joined together by an optically transparent adhesive or a snap-on method to form the light deflection element 30. In this way, when the light deflection element 30 is manufactured by a panelization method, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Of course, it should be understood that in another specific example of the present application, the first prism 361 can be a right-angled trapezoidal prism, and the second prism 362 can be a right-angled triangular prism or a right-angled trapezoidal prism. The first prism 361 and the second prism 362 are joined together by optically transparent adhesives or snaps to form a light turning element 30.

In another specific example of the present application, as shown in FIG3B , the split prism 36 also includes a third prism 363, wherein the first prism 361 is a right-angled trapezoidal prism, the second prism 362 is a rectangular prism, and the third prism 363 is a right-angled trapezoidal prism. The first prism 361, the second prism 362, and the third prism 363 are joined together by optically transparent adhesives or snaps to form a light deflection element 30. In this way, when the light deflection element 30 is manufactured by means of a panel assembly method, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Alternatively, the first prism 361 and the third prism 363 are triangular prisms, and the second prism 362 is a quadrilateral prism. For example, the first prism 361 and the third prism 363 are right-angled triangular prisms, and the second prism 362 is a rectangular prism. Alternatively, the first prism 361 and the third prism 363 are triangular prisms, and the second prism 362 is a parallelogram prism. The first prism 361, the second prism 362 and the third prism 363 are joined together by optically transparent adhesives or snaps to form a light turning element 30.

Continuing with reference to Figure 3A, in the split prism 36, when light passes through the light entrance area 311 of the first prism 361 and enters the first prism 361, at least some of the light is reflected at least once in the first prism 361 and reaches the second prism 362, and then at least some of the light reaching the second prism 362 is reflected at least once in the second prism 362 and reaches the light exit area 312 of the second prism 362, and is emitted from the second prism 362 to reach the photosensitive component 40.

Continuing with reference to Figure 3B, in the split prism 36, the second prism 362 is disposed between the first prism 361 and the third prism 363. When light passes through the light entrance area 311 of the first prism 361 and enters the first prism 361, at least some of the light is reflected at least once in the first prism 361 and reaches the second prism 362. Then, at least some of the light reaching the second prism 362 is reflected at least once in the second prism 362 and reaches the third prism 363. Finally, at least some of the light reaching the third prism 363 is reflected at least once in the third prism 363 and reaches the light exit area 312 of the third prism 363, and is emitted from the third prism 363 to reach the photosensitive component 40.

It should be understood that in the present application, the light entrance area 311 of the first prism 361 and the light exit area 312 of the third prism 363 are both arranged on the same side of the light deflection element 30 (split prism 36) so that light can enter and exit from the same side of the light deflection element 30. In this way, the optical lens 10 and the photosensitive component 40 can be concentrated on the same side of the light deflection element 30 to reduce the height of the camera module 1.

Furthermore, the light deflection element 30 may also include a shading film disposed between the first prism 361 and the second prism 362 and/or disposed between the second prism 362 and the third prism 363. Specifically, as shown in FIG3A and FIG3B , a U-shaped shading film is disposed on the side of the second prism 362 facing the first prism 361, and a U-shaped shading film is disposed on the side of the second prism 362 facing the third prism 363. It is understandable that the shading film may also be disposed on the side of the first prism 361 or the third prism 363 facing the second prism 362. By providing the shading film, the influence of stray light on imaging can be reduced, and the problem of glare can be reduced.

It should be understood that the split prism 36 may also include other numbers of prisms, such as four prisms, five prisms, six prisms, Of course, in other embodiments of the present application, the light deflection element 30 can also be implemented as a plurality of reflectors, and the plurality of reflectors are arranged at positions where the light needs to be reflected to form the light deflection element 30 .

In one embodiment of the present application, as shown in FIGS. 4 to 9C , the driving device 60 is implemented as a chip driving component, and the driving device 60 is configured to drive the photosensitive component 40 to move relative to the light deflection element 30 to achieve optical focus and/or optical image stabilization. It is worth mentioning that in this embodiment, the position of the optical lens 10 or the light deflection element 30 is not adjusted to keep the relative position between the optical lens 10 and the light deflection element 30 unchanged, thereby avoiding the reflection path of the light in the light deflection element 30 and the light emission path being significantly different from the predetermined path due to the change in the path of the light incident on the light deflection element 30, thereby reducing the imaging quality of the camera module 1. That is, the driving device 60 is configured to drive the photosensitive component 40 to move relative to the light deflection element 30 and the optical lens 10.

In one embodiment of the present application, the light deflection element 30 is disposed on the fixed part of the driving device 60, and the photosensitive component 40 is disposed on the movable part of the driving device 60. Further, the optical lens 10 is directly or indirectly fixed to the light deflection element 30, and the filter component 50 is directly or indirectly fixed to the photosensitive component 40. The driving device 60 can drive the photosensitive component 40 to move relative to the light deflection element 30, thereby changing the optical performance of the camera module 1 by moving the chip. That is, the photosensitive component 40 can move relative to the light deflection element 30 under the drive of the driving device 60 to achieve optical focus and/or optical image stabilization functions.

As mentioned above, when the light deflection element 30 is implemented as a trapezoidal prism, it includes a top side on which the optical lens 10 and the photosensitive component 40 are arranged, a bottom side opposite to the top side, and a peripheral side arranged between the top side and the bottom side. The peripheral side includes a first side 71, a second side 72, a third side 73 and a fourth side 74 arranged in sequence in a clockwise direction, wherein the first side 71 and the third side 73 are opposite, and the second side 72 and the fourth side 74 are opposite. The optical lens 10 is arranged close to the first side 71, and the photosensitive component 40 is arranged close to the third side 73. The lateral dimension of the light deflection element 30 at the top side is greater than the lateral dimension at the bottom side, that is, the lateral dimension of the light deflection element 30 gradually decreases from the top side to the bottom side along the optical axis direction. This allows a larger space between the peripheral side and the bottom side of the light deflection element 30 for arranging the driving device 60. It should be understood that the top side, the bottom side, the first side 71 , the second side 72 , the third side 73 and the fourth side 74 may also be applicable to other components in the camera module 1 .

In a specific example of the present application, the driving device 60 is arranged on the peripheral side of the light deflection element 30, and at least a part of the driving device 60 is lower than the top surface of the light deflection element 30. This arrangement, on the one hand, allows sufficient placement space for the driving device 60, making the structure of the camera module 1 more compact; on the other hand, it can reduce the height of the driving device 60, thereby reducing the shoulder height of the camera module 1, so as to provide a certain space position for the photosensitive component 40 and the filter component 50, and also achieve the purpose of reducing the height of the camera module 1. It should be understood that the shoulder height of the camera module 1 is the height of the driving device 60.

As shown in Figures 4 to 6, in one embodiment of the present application, the driving device 60 includes an upper cover 610a, a movable carrier 66a, a frame 63a, a fixed base 61a, a focus driving unit 62a, an anti-shake driving unit 65a and a connecting circuit board 44, wherein the upper cover 610a and the fixed base 61a form a accommodating cavity, and the movable carrier 66a, the frame 63a, the focus driving unit 62a, the anti-shake driving unit 65a and the connecting circuit board 44 are accommodated in the accommodating cavity. The movable carrier 66a is movably arranged on the frame 63a, and the frame 63a is movably arranged on the fixed base 61a. The anti-shake driving unit 65a is arranged between the movable carrier 66a and the frame 63a to drive the movable carrier 66a to move relative to the frame 63a along the X-axis and Y-axis directions, that is, the anti-shake driving unit 65a is configured to drive the movable carrier 66a to move relative to the frame 63a in a direction perpendicular to the optical axis of the camera module 1; the focus driving unit 62a is arranged between the frame 63a and the fixed base 61a to drive the frame 63a to move relative to the fixed base 61a along the Z-axis direction, that is, the focus driving unit 62a is configured to drive the frame 63a to move relative to the fixed base 61a in a direction parallel to the optical axis of the camera module 1. The connecting circuit board 44 is electrically connected to the focus driving unit 62a, the anti-shake driving unit 65a and the chip circuit board 42 to achieve circuit conduction of the driving device 60.

Furthermore, the light deflection element 30 and the optical lens 10 are arranged on the fixed base 61a of the driving device 60, and the photosensitive component 40 is transmissively arranged on the frame 63a of the driving device 60, so that when the focus driving unit 62a drives the frame 63a to move relative to the fixed base 61a in a direction parallel to the optical axis, the photosensitive component 40 moves accordingly in a direction parallel to the optical axis.

In other words, the driving device 60 includes: a fixed base 61a, the light deflection element 30 is fixed to the fixed base 61a; a frame 63a, the frame 63a is movably arranged on the fixed base 61a; a movable carrier 66a, the movable carrier 66a is movably arranged on the frame 63a, and the photosensitive component 40 is arranged on the movable carrier 66a; and an anti-shake driving unit 65a, the anti-shake driving unit 65a is arranged between the movable carrier 66a and the frame 63a, and is used to drive the movable carrier 66a to move relative to the frame 63a; wherein the anti-shake driving unit 65a is arranged on the peripheral side of the light deflection element 30, At least a portion of the anti-shake driving unit 65a is lower than the top surface of the light deflection element 30. In this way, the height of some components in the driving device 60 can be reduced, thereby reducing the shoulder height of the driving device 60 to achieve the purpose of reducing the height of the camera module 1.

The upper cover 610a and the fixed base 61a are interlocked to form a receiving chamber to accommodate the movable carrier 66a, the frame 63a, the focus drive unit 62a, the anti-shake drive unit 65a and the connecting circuit board 44, etc., which can prevent dust from entering on the one hand, and prevent the components from falling when hit on the other hand. Further, the upper cover 610a has a lens opening 6101a at the position corresponding to the optical lens 10, and the optical lens 10 can pass through the lens opening 6101a and be fixed to the light deflection element 30 to avoid affecting the incidence of light.

As shown in FIG. 6 , FIG. 7 and FIG. 9A , in one embodiment of the present application, the fixed base 61a includes a base body 611a and a bearing portion 613a disposed on the base body 611a, wherein the bearing portion 613a is disposed in the middle of the base body 611a and extends from the base body 611a in the height direction. The bearing portion 613a has a groove whose size gradually decreases from the top to the bottom along the optical axis direction, and the light deflection element 30 is fixed in the groove of the bearing portion 613a, and the shape of the groove of the bearing portion 613a is adapted to the shape of the light deflection element 30. Further, the height of the bearing portion 613a is not less than the height of the light deflection element 30, so as to avoid the top surface of the light deflection element 30 protruding from the top surface of the bearing portion 613a, thereby preventing the surface of the light deflection element 30 from being scratched or damaged. For example, in a specific example of the present application, the top surface of the light deflection element 30 is flush with the top surface of the bearing portion 613a.

It should be understood that due to the large size of the light deflection element 30, the bearing part 613a occupies most of the space in the driving device 60. In order to provide a certain space for other components of the driving device 60, the first side 71, the bottom side and the upper cover 610a of the bearing part 613a form a connection belt accommodating cavity 614a to accommodate the connection circuit board 44 therein; the third side 73, the bottom side and the upper cover 610a of the bearing part 613a form a drive part accommodating cavity 616a to accommodate the movable carrier 66a, the frame 63a, the focus drive part 62a, and the anti-shake drive part 65a therein. Among them, the connection belt accommodating cavity 614a and the drive part accommodating cavity 616a are relatively arranged on the peripheral side of the bearing part 613a, so as to avoid interference between the connection circuit board 44 and other components in the driving device 60, which affects the conductive effect, and can also make the structure of the camera module 1 more compact.

Further, the fixed base 61a also includes a focus fixing portion 612a, which is arranged on the side of the fixed base 61a, that is, the fixed base 61a includes a base body 611a extending in the horizontal direction, and a focus fixing portion 612a extending from the base body 611a in the height direction. In a specific example of the present application, the focus fixing portion 612a is arranged close to the side where the photosensitive component 40 is located, that is, the focus fixing portion 612a is arranged close to the third side 73 of the fixed base 61a. In order to make the space utilization rate in the driving device 60 higher, the focus fixing portion 612a is arranged on the second side 72 of the fixed base 61a, or, the fourth side 74 opposite to the second side 72.

Continuing to refer to Figures 6, 7 and 9A, in one embodiment of the present application, the frame 63a is movably disposed on the fixed base 61a, the movable carrier 66a is movably disposed on the frame 63a, and the photosensitive component 40 is fixedly disposed on the movable carrier 66a, so that when the frame 63a is driven to move along the Z-axis direction relative to the fixed base 61a, the frame 63a can drive the movable carrier 66a and then drive the photosensitive component 40 to move along the Z-axis direction to achieve the optical focusing function.

Further, the frame 63a includes an anti-shake frame 633a and a focus frame 631a, wherein the anti-shake frame 633a extends in the horizontal direction, and the focus frame 631a extends in the height direction integrally from the anti-shake frame 633a. That is, the frame 63a includes the anti-shake frame 633a extending in the horizontal direction, and the focus frame 631a extending in the height direction from the anti-shake frame 633a. When viewed from the plane in the height direction, the anti-shake frame 633a and the focus frame 631a form a "П"-shaped structure, which has an opening toward the bearing portion 613a. The movable carrier 66a and the anti-shake frame 633a are arranged opposite to each other in the height direction, the focus frame 631a and the focus fixing part 612a of the fixed base 61a are arranged opposite to each other in the horizontal direction, the anti-shake driving part 65a is arranged between the movable carrier 66a and the anti-shake frame 633a to drive the movable carrier 66a to move in the horizontal direction to realize the optical anti-shake function; the focus driving part 62a is arranged between the focus frame 631a and the focus fixing part 612a to drive the frame 63a and then drive the movable carrier 66a to move in the height direction to realize the optical focus function.

Further, the anti-shake frame 633a includes a first arm 6331a extending along the length direction (or X-axis direction) and a second arm 6332a extending along the width direction (or Y-axis direction), and the first arm 6331a and the second arm 6332a are connected to each other. It can also be said that the first arm 6331a of the anti-shake frame 633a is set on the second side 72 or the fourth side 74, the second arm 6332a of the anti-shake frame 633a is set on the third side 73, and the focus frame 631a is set on the side opposite to the first arm 6331a of the anti-shake frame 633a and extends in the height direction. It should be understood that in the present application, the frame 63a is only set on three sides close to the photosensitive component 40, for example: the second side 72, the third side 73 and the fourth side 74, toward the optical lens. The frame 63a is not provided on one side of the head 10, for example, the first side 71. This arrangement can reduce the size of a single side of the driving device 60, so as to reduce the lateral size of the camera module 1.

As shown in Figures 6 to 9A, in an embodiment of the present application, the focus drive unit 62a is arranged on the side of the drive device 60, and the focus drive unit 62a is arranged between the fixed base 61a and the frame 63a along the height direction to drive the frame 63a to move relative to the fixed base 61a along the Z-axis direction, that is, the focus drive unit 62a is configured to drive the frame 63a to move relative to the fixed base 61a along a direction parallel to the optical axis of the camera module 1 to achieve an optical focus function. For example, in a specific example of the present application, the focus drive unit 62a is arranged between the focus frame 631a of the frame 63a and the focus fixing portion 612a of the fixed base 61a. The focus driving part 62a includes a focus magnet 621a and a focus coil 622a opposite thereto, the focus magnet 621a is arranged at one of the focus frame 631a and the focus fixing part 612a, and the focus coil 622a is arranged at the other of the focus frame 631a and the focus fixing part 612a. In a specific example of the present application, the focus magnet 621a and the focus coil 622a are arranged relatively on the circumference of the light turning element 30 in the horizontal direction; wherein the winding axis of the focus coil 622a is parallel to the optical axis direction of the camera module 1. It should be understood that in the present application, the focus coil 622a is wound around an axis in the height direction, and the axis is the winding axis of the focus coil 622a. In other words, the focus coil 622a is formed by winding a wire around the winding axis.

In one embodiment of the present application, the focus magnet 621a is disposed on the focus frame 631a, and the focus coil 622a is disposed on the focus fixing portion 612a. The focus magnet 621a and the focus coil 631a interact to drive the focus frame 631a to move relative to the focus fixing portion 612a in a direction parallel to the optical axis of the camera module 1. For example, in a specific example of the present application, the outer wall of the focus frame 631a has a magnet placement groove, and the focus magnet 621a is disposed in the magnet placement position to be fixed to the focus frame 631a. The focus fixing portion 612a includes a first support arm 6121a and a second support arm 6122a which are spaced apart from each other. The first support arm 6121a and the second support arm 6122a extend integrally from the base body 611a in the height direction. There is a certain space between the first support arm 6121a and the second support arm 6122a. The focus coil 622a is disposed in the space between the first support arm 6121a and the second support arm 6122a. Further, the first support arm 6121a and the second support arm 6122a are respectively provided with coil placement grooves, the opening of the coil placement grooves faces the space between the first support arm 6121a and the second support arm 6122a, and the focus coil 622a is disposed in the coil placement grooves to be stably clamped between the first support arm 6121a and the second support arm 6122a.

As shown in FIGS. 7 to 9B , it should be understood that the focusing magnet 621a and the focusing coil 622a are arranged relative to each other in the horizontal direction, so that the frame 63a is driven to move relative to the fixed base 61a through the magnetic field force between the focusing coil 622a and the focusing magnet 621a. The greater the magnetic field force between the focusing coil 622a and the focusing magnet 621a, the greater the stroke that can drive the frame 63a to move along the optical axis. In the present application, the focus drive unit 62a also includes a magnetic conductive member 624a, which is arranged between the first support arm 6121a and the second support arm 6122a, and the magnetic conductive member 624a extends in the height direction, and its top surface is not higher than the top surfaces of the first support arm 6121a and the second support arm 6122a. The focus coil 622a is wound around the magnetic conductive part 624a along the height direction, and the winding height of the focus coil 622a does not exceed the height of the magnetic conductive part 624a to prevent the focus coil 622a from falling off the magnetic conductive part 624a. In this arrangement, on the one hand, the magnetic conductive part 624a is arranged inside the focus coil 622a. When the focus coil 622a is energized, the magnetic field of the magnetic conductive part 624a is magnetized to generate a magnetic field. The magnetic field generated by the magnetic conductive part 624a and the magnetic field generated by the focus coil 622a are superimposed on each other, so that the overall magnetic field strength is increased, the magnetic field force between the focus coil 622a and the focus magnet 621a is increased, and the driving frame 63a has a larger moving stroke. On the other hand, since the magnetic conductive part 624a extends in the height direction and has a certain height, the number of turns of the focusing coil 622a wound on the magnetic conductive part 624a increases, the magnetic field force between the focusing coil 622a and the focusing magnet 621a increases, and the driving frame 63a produces a larger moving stroke.

In one embodiment of the present application, the focus coil 622a and the focus magnet 621a extend in the height direction, and the height of the focus coil 622a is greater than the height of the focus magnet 621a. That is, the focus coil 622a is arranged on the side wall of the focus fixing portion 612a, and the focus magnet 621a is arranged on the side wall of the focus frame 631a, and the height of the focus coil 622a is greater than the height of the focus magnet 621a, so that the focus magnet 621a can always interact with the focus magnet 622a during the movement of the focus frame 631a.

Further, in one embodiment of the present application, the height of the focus drive unit 62a is greater than the height of the photosensitive component 40, and the magnetic conductive member 624a of the focus drive unit 62a extends in the height direction to a position close to the upper cover 610a, and the top surface of the magnetic conductive member 624a is higher than the top surface of the photosensitive component 40. It should be understood that the photosensitive component 40 moves in the Z-axis direction under the drive of the focus drive unit 62a, and the photosensitive component 40 needs to have enough space in the height direction to satisfy its moving stroke. During the optical focusing process, the magnetic conductive member 624a and the focus coil 622a are stators, which have a higher height to provide a greater driving force. The top surface of the photosensitive component 40 is lower than the top surface of the magnetic conductive member 624a, and also satisfies the larger height of the photosensitive component 40. Mobile travel needs.

It should be understood that in the present application, the focus coil 622a is arranged on the peripheral side of the magnetic conductive member 624a, and the magnetic conductive member 624a has a certain thickness so that it has sufficient strength to support the focus coil 622a. However, since the magnetic conductive member 624a and the focus magnet 621a are arranged relative to each other in the horizontal direction, the magnetic conductive member 624a and the focus magnet 621a interact with each other to generate a magnetic attraction force in the horizontal direction to movably hold the frame 63a in the fixed base 61a. When the magnetic attraction force between the magnetic conductive member 624a and the focus magnet 621a is too large, that is, the magnetic attraction force between the magnetic conductive member 624a and the focus magnet 621a is greater than the magnetic thrust generated by the interaction between the focus magnet 621a and the focus coil 622a, the frame 63a cannot move under the action of the magnetic thrust. In order to avoid the above situation, in the present application, the magnetic conductive member 624a is a hollow structure, and there is a through hole in the middle of the magnetic conductive member 624a to reduce the magnetic attraction between the magnetic conductive member 624a and the focusing magnet 621a. When the magnetic attraction between the magnetic conductive member 624a and the focusing magnet 621a is less than the magnetic thrust generated by the interaction between the focusing magnet 621a and the focusing coil 622a, the frame 63a can move under the action of the magnetic thrust. Of course, the size of the through hole of the magnetic conductive member 624a is determined according to actual needs.

Among them, the focusing coil 622a can be implemented as being directly wound around the circumference of the magnetic conductive component 624a, or it can be implemented as being prefabricated and then placed on the circumference of the magnetic conductive component 624a; the magnetic conductive component 624a can be implemented as an iron core, or it can be implemented as other metal materials, and the present application does not impose any restrictions on this.

In a specific example of the present application, the magnetic conductive member 624a is disposed in the coil placement groove so that the focus coil 622a is stably disposed between the first support arm 6121a and the second support arm 6122a. Further, the bottom of the magnetic conductive member 624a has a larger size, which is larger than the size of other parts of the magnetic conductive member 624a. For example, the magnetic conductive member 624a has a "⊥"-shaped structure, so that, on the one hand, the focus coil 622a can be prevented from falling off; on the other hand, it can be more stably disposed on the first support arm 6121a and the second support arm 6122a.

As shown in FIG8B , in another embodiment of the present application, the magnetic conductive member 624a is disposed on a side of the focusing coil 622a away from the focusing magnet 621a, and the magnetic conductive member 624a and the focusing magnet 621a are disposed opposite to each other in the horizontal direction. Furthermore, the magnetic conductive member 624a extends in the height direction and is disposed between the positioning piece 615a and the base body 611a, that is, the two ends of the magnetic conductive member 624a are respectively fixed by the positioning piece 615a and the base body 611a. When the magnetic conductive member 624a interacts with the focusing magnet 621a to generate a magnetic attraction force in the horizontal direction, under the action of the magnetic attraction force, the frame 63a is movably retained in the fixed base 61a. In this embodiment, the magnetic conductive member 624a can be implemented as a metal sheet, such as an iron sheet.

It should be understood that the focusing coil 622a can also be implemented as a planar racetrack coil, and the plane where the focusing coil 622a is located is parallel to the plane where the magnetic conductive member 624a is located, so that when the magnetic conductive member 624a is set, there will be no interference between the focusing coil 622a.

Continuing to refer to Figures 6 and 9A, in an embodiment of the present application, the drive device 60 also includes a focus guide portion 64a, which is clamped between the frame 63a and the fixed base 61a, and the extension direction of the focus guide portion 64a is parallel to the optical axis of the camera module 1. When the focus drive portion 62a drives the frame 63a to move along the Z-axis direction, the focus guide portion 64a always supports the frame 63a, so that the frame 63a can move smoothly relative to the fixed base 61a, thereby improving the stability of the movement of the drive device 60 during the optical focusing process, thereby improving the imaging quality. In a specific example of the present application, the focus guide portion 64a is arranged on the same side as the focus drive portion 62a, and the focus guide portion 64a is arranged between the focus frame 631a of the frame 63a and the focus fixing portion 612a of the fixed base 61a. Furthermore, the focus guide portion 64a includes a top surface, a bottom surface opposite to the top surface, and an outer peripheral wall connected between the top surface and the bottom surface, and the outer peripheral wall of the focus guide portion 64a abuts against the focus fixing portion 612a and the focus frame 631a respectively.

In one embodiment of the present application, a first guide rail 6123a is provided on one side of the focus fixing portion 612a facing the focus frame 631a, and a second guide rail 632a is provided on one side of the focus frame 631a facing the focus fixing portion 612a. The first guide rail 6123a and the second guide rail 632a are arranged opposite to each other to clamp the focus guide portion 64a therebetween. The length of the first guide rail 6123a along the height direction is greater than the length of the second guide rail 632a along the height direction, and the length of the focus guide portion 64a along the height direction is greater than the length of the second guide rail 632a along the height direction, so as to prevent the frame 63a from being separated from the focus guide portion 64a during movement.

In an embodiment of the present application, the focus guide portion 64a may be implemented as a guide rod 641a, or the focus guide portion 64a may also be implemented as a ball.

Further, in one embodiment of the present application, the first support arm 6121a and the second support arm 6122a have two first guide rails 6123a, the focus frame 631a has two second guide rails 632a, and the two first guide rails 6123a and the second guide rail 632a are arranged opposite to each other. In other words, There are two first guide rails 6123a, which are arranged in parallel with each other and are respectively arranged on the first support arm 6121a and the second support arm 6122a. Correspondingly, there are two second guide rails 632a, which are arranged in parallel with each other and are respectively arranged on both sides of the magnet placement position. The two second guide rails 632a and the two first guide rails 6123a are arranged in parallel with each other. The focus guide part 64a includes two guide rods 641a, which are clamped between the two first guide rails 6123a and the two second guide rails 632a.

In the present application, the shapes of the first guide rail 6123a and the second guide rail 632a can be a planar structure, a "∟"-shaped structure, a "["-shaped structure or a "〈"-shaped structure, that is, the contact points between the focus guide portion 64a and the first guide rail 6123a or the second guide rod 641a are one, two or three, so that the focus guide portion 64a can be firmly clamped between the first guide rail 6123a and the second guide rail 632a. In a specific example of the present application, the two first guide rails 6123a are in a "∟"-shaped structure to facilitate their molding on the first support arm 6121a and the second support arm 6122a; the two second guide rails 632a are in a "["-shaped structure or a "〈"-shaped structure. Of course, the two second guide rails 632a can also be in a "["-shaped and "〈"-shaped structures, respectively.

As shown in FIGS. 6 to 9A , it should be understood that although the extension direction of the focus guide 64a is parallel to the optical axis direction, the focus guide 64a may still be tilted during the movement of the frame 63a, thereby affecting the driving effect. In the present application, the fixed base 61a further includes a positioning piece 615a, the positioning piece 615a is fixed to the fixed base 61a, and the bottom surface of the positioning piece 65a abuts against the top surface of the focus guide 64a. That is, one end of the focus guide 64a is fixed to the base body 611a, and the other end of the focus guide 64a is fixed to the positioning piece 615a.

The plane where the positioning piece 615a is located is parallel to the plane where the base body 611a is located, the bottom surface of the focus guide part 64a is fixed to the base body 611a, and the top surface of the focus guide part 64a abuts against the positioning piece 615a to keep the focus guide part 64a parallel to the optical axis of the camera module 1.

Furthermore, although the two guide rods 641a are arranged relatively parallel, the two guide rods 641a may still be tilted and interfere with each other during the movement of the frame 63a. When the two guide rods 641a are clamped between the positioning piece 615a and the base body 611a, the two guide rods 641a always remain parallel under the action of the positioning piece 615a during the movement of the frame 63a for optical focusing, so that the parallelism between the two guide rods 641a is guaranteed.

Further, the top ends of the first support arm 6121a and the second support arm 6122a of the focus fixing portion 612a are provided with positioning bosses 6124a, and the positioning piece 615a has a corresponding positioning hole 6151a, and the positioning bosses 6124a are arranged in the positioning hole 6151a, so that the positioning piece 615a is placed at the top ends of the first support arm 6121a and the second support arm 6122a. There is no gap between the focus guide portion 64a and the positioning piece 615a, so that the focus guide portion 64a can be stably arranged between the positioning piece 615a and the base body 611a of the fixed base 61a. For example, in a specific example of the present application, the length of the focus guide portion 64a along the height direction is equal to the height of the first support arm 6121a and the second support arm 6122a, so that the top surface of the focus guide portion 64a and the bottom surface of the positioning piece 615a are in contact with each other.

It should be understood that the positioning piece 615a covers at least a portion of the top surface of the focus guide portion 64a in the horizontal direction, so as to support and fix the focus guide portion 64a through the positioning piece 615a. Of course, the positioning piece 615a can cover the entire top surface of the focus guide portion 64a in the horizontal direction, and the present application does not limit this. In other words, the positioning piece 615a covers at least a portion of the top surface of the two guide rods 641a in the horizontal direction to keep the two guide rods 641a arranged parallel to each other.

As mentioned above, the magnetic conductive member 624a and the focusing magnet 621a are arranged opposite to each other in the horizontal direction. The interaction between the magnetic conductive member 624a and the focusing magnet 621a generates a magnetic attraction force in the horizontal direction. The magnetic attraction force causes the focusing guide portion 64a to be clamped between the focusing frame 631a and the focusing fixing portion 612a. In the process of realizing the optical focusing function, the focusing guide portion 64a always provides support for the focusing frame 631a. Furthermore, the magnetic conductive member 624a and the focusing magnet 621a are arranged relative to each other in the horizontal direction, so that a magnetic attraction force is generated in the horizontal direction between the magnetic conductive member 624a and the focusing magnet 621a. Under the action of the magnetic attraction force, frictional contact is always maintained between the focusing frame 631a and the focusing guide portion 64a, and between the focusing guide portion 64a and the focusing fixing portion 612a, so as to maintain the stability of the frame 63a and effectively prevent the frame 63a from falling off due to the shaking or inversion of the camera module 1.

As shown in Fig. 6, Fig. 7, Fig. 9A and Fig. 9B, in one embodiment of the present application, the movable carrier 66a is movably disposed on the frame 63a, the photosensitive component 40 is fixedly disposed on the movable carrier 66a, and the anti-shake driving unit 65a is disposed between the movable carrier 66a and the frame 63a to drive the movable carrier 66a and then drive the photosensitive component 40 to move relative to the frame 63a along the X-axis and Y-axis directions to achieve the optical anti-shake function. In a specific example of the present application, the movable carrier 66a is disposed on the anti-shake frame 633a of the frame 63a, that is, along the height direction, the movable carrier 66a, the anti-shake frame 633a and the fixed base 61a are disposed in sequence.

It should be understood that the movable carrier 66a is arranged on the upper part of the anti-shake frame 633a, and the anti-shake frame 633a is arranged on the upper part of the base body 611a. At least a part of the movable carrier 66a is lower than the top surface of the light deflection element 30, that is, the position of the movable carrier 66a is the highest among the three. In the present application, at least a part of the movable carrier 66a is lower than the top surface of the light deflection element 30. Since the anti-shake frame 633a and the fixed base 61a are both located at the lower part of the movable carrier 66a, the anti-shake frame 633a and the fixed base 61a are also lower than the top surface of the light deflection element 30. In this way, the height of some components in the driving device 60 can be reduced, and then the shoulder height of the driving device 60 can be reduced, so as to achieve the purpose of reducing the height of the camera module 1.

In the present application, the movable carrier 66a is disposed between the frame 63a and the photosensitive component 40, the photosensitive component 40 is fixedly disposed on the movable carrier 66a, and the movable carrier 66a is movably connected to the frame 63a, so that when the movable carrier 66a is driven by the anti-shake driving unit 65a, the photosensitive component 40 moves with the movable carrier 66a. In a specific example of the present application, the photosensitive component 40 is supported on the movable carrier 66a by the filter element holder 52 of the filter component 50, that is, the filter element holder 52 is disposed between the chip circuit board 42 and the movable carrier 66a, and one end of the filter element holder 52 is fixed to the chip circuit board 42, and the other end is fixed to the movable carrier 66a.

In one embodiment of the present application, the movable carrier 66a is in an "L" shape, that is, the movable carrier 66a includes a third arm 662a extending along the length direction (or the X-axis direction) and a fourth arm 663a extending along the width direction (or the Y-axis direction), and the third arm 662a and the fourth arm 663a are connected to each other. Further, the third arm 662a of the movable carrier 66a and the first arm 6331a of the anti-shake frame 633a are arranged opposite to each other in the height direction, and the fourth arm 663a of the movable carrier 66a and the second arm 6332a of the anti-shake frame 633a are arranged opposite to each other in the height direction, so that the anti-shake driving unit 65a is arranged between the movable carrier 66a and the anti-shake frame 633a. In other words, the movable carrier 66a is only arranged on two sides close to the photosensitive component 40, for example: the second side 72 and the third side 73, or the fourth side 74 and the third side 73.

The movable carrier 66a includes two openings, one of which faces the side where the focus driving unit 62a is located, and the other faces the side where the optical lens 10 is located. For example, when the focus driving unit 62a is disposed on the second side 72 of the driving device 60, one opening of the movable carrier 66a faces the second side 72, and the other faces the first side 71, the third arm 662a of the movable carrier 66a is disposed on the fourth side 74, and the fourth arm 663a of the movable carrier 66a is disposed on the third side 73. This arrangement can make full use of the space inside the camera module 1, and the movable carrier 66a is not disposed on the side facing the focus driving unit 62a and the side facing the light deflection element 30, thereby avoiding increasing the size of the camera module 1 in the horizontal direction.

In one embodiment of the present application, the anti-shake driving unit 65a is arranged between the movable carrier 66a and the frame 63a in the horizontal direction to drive the movable carrier 66a and then drive the photosensitive component 40 to move relative to the frame 63a along the X-axis and Y-axis directions. It should be understood that the anti-shake driving unit 65a extends downward from the movable carrier 66a to the peripheral side of the light turning element 30, and at least a part of the anti-shake driving unit 65a is lower than the top surface of the light turning element 30. This arrangement can reduce the height of the position where the anti-shake driving unit 65a is located, thereby reducing the shoulder height of the driving device 60, so as to achieve the purpose of reducing the height of the camera module 1. The anti-shake driving unit 65a includes at least one anti-shake magnet 651a and at least one anti-shake coil 652a, at least one anti-shake magnet 651a is arranged on one of the movable carrier 66a and the frame 63a, at least one anti-shake coil 652a is arranged on the other of the movable carrier 66a and the frame 63a, and at least one anti-shake magnet 651a and at least one anti-shake coil 652a are arranged opposite to each other in the height direction. In a specific example of the present application, at least one anti-shake coil 652a is arranged on the movable carrier 66a, and at least one anti-shake magnet 651a is arranged on the anti-shake frame 633a.

Furthermore, the plane where the top surface of at least one anti-shake magnet 651a is located is lower than the plane where the top surface of the light deflection element 30 is located, and the plane where the bottom surface of at least one anti-shake coil 652a is located is lower than the plane where the top surface of the light deflection element 30 is located. That is, in the present application, at least one anti-shake magnet 651a and at least one anti-shake coil 652a are arranged on the peripheral side of the light deflection element 30, and the placement positions of at least one anti-shake magnet 651a and at least one anti-shake coil 652a can be further lowered, thereby reducing the shoulder height of the driving device 60, so as to achieve the purpose of reducing the height of the camera module 1.

In the present application, the anti-shake drive unit 65a is arranged in the horizontal direction, and the focus drive unit 62a is arranged in the height direction. The plane where the anti-shake drive unit 65a is located is perpendicular or approximately perpendicular to the plane where the focus drive unit 62a is located. The focus drive unit 62a drives the frame 63a, the anti-shake drive unit 65a and the movable carrier 66a to move in the height direction to achieve optical focus; the anti-shake drive unit 65a drives the movable carrier 66a to move in the horizontal direction to achieve optical image stabilization.

As shown in Figures 6, 7 and 9A, at least one anti-shake magnet 651a includes a first anti-shake magnet 6511a and a second anti-shake magnet 6512a, and at least one anti-shake coil 652a includes a first anti-shake coil 6521a and a second anti-shake coil 6522a. The length direction of the first anti-shake magnet 6511a is the X-axis direction, and the length direction of the second anti-shake magnet 6512a is the Y-axis direction, that is, the first anti-shake magnet 6511a and the second anti-shake magnet 6512a are arranged in a vertical or approximately vertical manner. The length direction of the first anti-shake coil 6521a is the same as the length direction of the camera module 1, for example, the X-axis direction. Direction, the length direction of the second anti-shake coil 6522a is the same as the width direction of the camera module 1, for example, the Y-axis direction, that is, the first anti-shake coil 6521a and the second anti-shake coil 6522a are arranged in a vertical or approximately vertical manner.

Specifically, in one embodiment of the present application, the first anti-shake magnet 6511a is arranged on the first arm 6331a of the anti-shake frame 633a, the second anti-shake magnet 6512a is arranged on the second arm 6332a of the anti-shake frame 633a, the first anti-shake coil 6521a is arranged on the third arm 662a of the movable carrier 66a, and the second anti-shake coil 6522a is arranged on the fourth arm 663a of the movable carrier 66a. The first anti-shake magnet 6511a and the first anti-shake coil 6521a are arranged opposite to each other in the height direction, and the second anti-shake magnet 6512a and the second anti-shake coil 6522a are arranged opposite to each other in the height direction, so that the first anti-shake magnet 6511a and the first anti-shake coil 6521a interact with each other, and the second anti-shake magnet 6512a and the second anti-shake coil 6522a interact with each other, thereby generating a magnetic field force to drive the movable carrier 66a to move along the X-axis and Y-axis directions.

It should be understood that in the present application, the number of the first anti-shake coils 6521a can be two, the length direction of the two first anti-shake coils 6521a is the same as the length direction of the camera module 1, and the two first anti-shake coils 6521a are arranged side by side along the length direction of the camera module 1. The two first anti-shake coils 6521a and the first anti-shake magnet 6511a are arranged opposite to each other in the height direction to increase the magnetic field force between the two. Of course, the number of the second anti-shake coils 6522a can also be two, the length direction of the two second anti-shake coils 6522a is the same as the width direction of the camera module 1, and the two second anti-shake coils 6522a are arranged side by side along the width direction of the camera module 1. The number of the first anti-shake coils 6521a and the second anti-shake coils 6522a can also be three, four, etc., and the present application does not limit this.

The driving device 60 further includes an anti-shake support part 67a, which is arranged between the movable carrier 66a and the frame 63a. When the anti-shake driving part 65a drives the movable carrier 66a to move along the X-axis direction and the Y-axis direction, the anti-shake support part 67a always supports the movable carrier 66a, so that the movable carrier 66a can move smoothly relative to the frame 63a. The stability of the movement of the driving device 60 during the optical anti-shake process is improved, thereby improving the imaging quality.

The top surface of the anti-shake frame 633a of the frame 63a is provided with a first ball groove 634a, and the bottom surface of the movable carrier 66a is provided with a second ball groove 661a. The first ball groove 634a and the second ball groove 661a are arranged opposite to each other in the height direction, and the anti-shake support part 67a is clamped in the first ball groove 634a and the second ball groove 661a. The diameter of the first ball groove 634a and the diameter of the second ball groove 661a are both larger than the diameter of the anti-shake support part 67a, so that the anti-shake support part 67a can roll in the horizontal direction in the space formed by the first ball groove 634a and the second ball groove 661a.

Further, the number of the first ball grooves 634a is three, which are respectively arranged at the end of the first arm 6331a of the anti-shake frame 633a, the end of the second arm 6332a, and the connection between the first arm 6331a and the second arm 6332a; the number of the second ball grooves 661a is three, which are respectively arranged at the end of the third arm 662a of the movable carrier 66a, the end of the fourth arm 663a, and the connection between the third arm 662a and the fourth arm 663a. Correspondingly, the number of the anti-shake support parts 67a is three, which are respectively arranged in the three first ball grooves 634a and the three second ball grooves 661a to provide more stable support for the movable carrier 66a. In one embodiment of the present application, the anti-shake support part 67a can be implemented as a ball 671a or a slider. It should be understood that the number of the anti-shake support parts 67a is at least three, that is, it can be four, five or other numbers.

Furthermore, in one embodiment of the present application, the driving device 60 further includes an anti-shake magnetic sheet (not shown in the drawings), which is disposed on the movable carrier 66a and is disposed opposite to the anti-shake magnet 651a in the height direction. The interaction between the anti-shake magnetic sheet and the anti-shake magnet 651a generates a magnetic attraction, and the magnetic attraction causes the anti-shake support portion 67a to be clamped between the movable carrier 66a and the frame 63a. In the process of realizing optical image stabilization, the anti-shake support portion 67a always provides support for the movable carrier 66a. The anti-shake magnetic sheet and at least one anti-shake magnet 651a are arranged opposite to each other in the height direction, so that a magnetic attraction force is generated between the anti-shake magnetic sheet and the anti-shake magnet 651a in the height direction. Under the action of the magnetic attraction force, the movable carrier 66a and the anti-shake support part 67a, as well as the frame 63a and the anti-shake support part 67a always maintain friction contact, that is, the anti-shake support part 67a is clamped between the movable carrier 66a and the anti-shake frame 633a under the action of the magnetic attraction force to maintain the stability of the movable carrier 66a. The anti-shake magnetic member is made of a material that can attract magnets, such as an iron sheet.

It should be understood that the anti-shake magnetic sheet is arranged on the side of the anti-shake coil 652a away from the anti-shake magnet 651a. For example, the anti-shake magnetic sheet is fixed between the anti-shake coil 652a and the movable carrier 66a by gluing or welding, or the anti-shake magnetic sheet is arranged inside the movable carrier 66a by insert injection molding. The present application does not impose any restrictions on this.

In one embodiment of the present application, the driving device 60 further includes a frame cover 630a, and the frame cover 630a and the frame 63a are anti-shake The frame 633a is buckled to accommodate the anti-shake driving unit 65a, the movable carrier 66a, the anti-shake support unit 67a, the anti-shake magnetic sheet and other components between the frame cover 630a and the anti-shake frame 633a of the frame 63a, so as to prevent the components from falling off during the optical anti-shake process and affecting the anti-shake effect. Further, the frame cover 630a corresponds to the structure of the anti-shake frame 633a, and is in an "L"-shaped structure to buckle with the first arm 6331a and the second arm 6332a of the anti-shake frame 633a.

In one embodiment of the present application, the driving device 60 further includes an anti-shake position sensing component 68a and a focus position sensing component 69a, and the anti-shake position sensing component 68a includes an anti-shake position sensing element 681a. The anti-shake position sensing element 681a is provided on a movable carrier 66a, and is arranged opposite to the anti-shake magnet 651a. When the movable carrier 66a moves, the relative position of the anti-shake position sensing element 681a and the anti-shake magnet 651a changes. According to the strength of the magnetic field of the anti-shake magnet 651a sensed by the anti-shake position sensing element 681a, the position of the movable carrier 66a can be determined, and then the current of the anti-shake coil 652a is adjusted to move the movable carrier 66a to the required position. In a specific example of the present application, the anti-shake position sensing element 681a is provided in the anti-shake coil 652a to avoid increasing the size of the movable carrier 66a. The anti-shake position sensing element 681a can be implemented as a TMR, a Hall element or a driver IC, etc.

The focus position sensing component 69a includes a focus position sensing element 692a and a focus position sensing magnet 691a, wherein the focus position sensing element 692a is arranged on the focus fixing portion 612a of the fixed base 61a, and the focus position sensing magnet 691a is arranged on the focus frame 631a of the frame 63a, and the focus position sensing element 692a and the focus position sensing magnet 691a are arranged relatively in the horizontal direction. When the frame 63a moves, the relative position of the focus position sensing element 692a and the focus position sensing magnet 691a changes. According to the strength of the magnetic field of the focus position sensing magnet 691a sensed by the focus position sensing element 692a, the position of the frame 63a can be determined, and then the current of the focus coil 622a is adjusted to move the frame 63a to the required position. In a specific example of the present application, the focus position sensing magnet 691a is a magnetic grating structure to meet the larger movement travel requirements of the frame 63a. The focus position sensing element 692a may be implemented as a TMR, a Hall element, a driving IC, or the like.

As can be seen from the above embodiment, the focus driving unit 62a, the anti-shake driving unit 65a, the movable carrier 66a, the frame 63a and other components of the driving device 60 are centrally arranged in the driving unit accommodating cavity 616a. In other words, the focus driving unit 62a, the anti-shake driving unit 65a, the movable carrier 66a, the frame 63a and other components of the driving device 60 are centrally arranged on one side of the light deflection element 30 along the length direction, so as to fully utilize the internal space of the camera module 1.

In one embodiment of the present application, the camera module 1 further includes a focus electrical connection portion (not shown) and an anti-shake electrical connection portion (not shown), wherein the focus electrical connection portion and the anti-shake electrical connection portion are electrically connected to the connection circuit board 44, respectively. In a specific example of the present application, the focus electrical connection portion can be integrally formed on the fixed base 61a using an insert injection molding process to electrically connect the focus coil 622a and the connection circuit board 44 to achieve circuit conduction of the focus drive portion 62a. In another specific example of the present application, the focus electrical connection portion can be implemented as a PIN pin to electrically connect the focus coil 622a and the connection circuit board 44.

In a specific example of the present application, the anti-shake electrical connection portion can be integrally formed on the movable carrier 66a by insert injection molding to be electrically connected to the anti-shake coil 652a and the connection circuit board 44 to achieve circuit conduction of the anti-shake driving portion 65a. In another specific example of the present application, the anti-shake electrical connection portion can be implemented as a PIN pin to be electrically connected to the anti-shake coil 652a and the connection circuit board 44.

Furthermore, the photosensitive component 40 also includes a connecting circuit board 44, which is fixed and electrically connected to the chip circuit board 42 to provide electrical conduction between the chip circuit board 42 and the external electronic device. The applicant found that when the photosensitive component 40 is driven by the driving device 60 to move, the connecting circuit board 44 will become one of the sources of resistance to the movement of the photosensitive component 40. Therefore, in this application, the applicant further improves the connecting circuit board 44 of the photosensitive component 40 to reduce the resistance encountered by the photosensitive component 40 when it is driven to achieve chip anti-shake or chip focus.

As further shown in FIG. 6 and FIG. 9C , the connection circuit board 44 includes a first connection belt 45a, and the first connection belt 45a includes a first connection portion 451a, a first side connection portion 452a, a first bending portion 453a and a first lead-out portion 454a connected in sequence, wherein the first connection portion 451a connects the chip circuit board 42 and the first side connection portion 452a, and the first bending portion 453a connects the first side connection portion 452a and the first lead-out portion 454a. It should be understood that the first connection portion 451a, the first side connection portion 452a, the first bending portion 453a and the first lead-out portion 454a are electrically connected, and the first connection belt 45a is connected and electrically connected to the chip circuit board 42 through the first connection portion 451a, so that the chip circuit board 42 can be electrically connected to an external device or equipment through the first lead-out portion 454a of the first connection belt 45a. It is worth mentioning that in the present application, the first connection belt 45a can be a flexible circuit board or a hard-soft board, so that the first connecting strip 45a can be bent to adapt to the space inside the camera module 1.

Specifically, the first connection portion 451a extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42, one end of the first connection portion 451a is connected to the chip circuit board 42, and the other end of the first connection portion 451a is bent downward and connected to one end of the first side connection portion 452a. The first side connection portion 452a extends and bends around the periphery of the light turning element 30 and the optical lens 10, so that the first side connection portion 452a is bent from the long side of the camera module 1 to the short side of the camera module 1, and the other end of the first side connection portion 452a is connected to one end of the first bending portion 453a. One end of the first bending portion 453a is connected to the bottom of the other end of the first side connection portion 452a, and the other end of the first bending portion 453a is connected to the first lead-out portion 454a, and the first bending portion 453a is bent and arranged below the first side connection portion 452a. In a specific example, the first bending portion 453a is bent in the horizontal direction, and the first bending portion 453a is disposed below the first side connecting portion 452a in the form of a horizontal bend. It should be understood that, as shown in the drawings in the present application, in the present application, the direction of the optical lens 10 relative to the light deflection element 30 is considered as the upper direction, and the opposite direction is considered as the lower direction. In other words, the light deflection element 30 is below the optical lens 10.

It should be understood that, by setting the first side connection portion 452a, the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the horizontal direction is reduced, and by setting the first bending portion 453a, the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the height direction can be reduced. In particular, in the present application, the driving device 60 drives the photosensitive component 40 to move in the height direction to a stroke of at least 2 mm, and the first bending portion 453a can be extended and retracted in the height direction to meet the requirements of the photosensitive component 40 moving in the height direction. Furthermore, the first bending portion 453a can be bent multiple times so that the first bending portion 453a can have a longer extension stroke in the height direction.

It is worth mentioning that in order to design the size of the camera module 1 to be smaller, in the present application, the fixed base 61a also includes a connecting belt accommodating cavity 614a formed between the base body 611a and the supporting portion 613a, and the connecting belt accommodating cavity 614a is arranged on the side of the fixed base 61a close to the optical lens 10, and the connecting belt accommodating cavity 614a is located below the optical lens 10 and the light turning element 30, and the first bending portion 453a is accommodated in the connecting belt accommodating cavity 614a, thereby avoiding an increase in the length of the camera module 1. The first connecting strip 45a extends from the chip circuit board 42 to the side close to the optical lens 10 (i.e., to the side away from the focus driving unit 62a and the anti-shake driving unit 65a), so that part of the first connecting strip 45a is bent below the optical lens 10 and the light deflection element 30, so that part of the first connecting strip 45a is arranged in the connecting strip accommodating cavity 614a of the fixed base 61a, optimizing the spatial configuration in the camera module 1, thereby reducing the size of the camera module 1. It is worth mentioning that the bottom of the light deflection element 30 refers to the bottom of the top surface of the light deflection element 30, that is, the bottom of the first surface 31 of the light deflection element 30. Further, the bottom of the light deflection element 30 further refers to the bottom of the second surface 32 of the light deflection element 30, part of the first connecting strip 45a is bent below an inclined surface (second surface 32) of the light deflection element 30, and the connecting strip accommodating cavity 614a is located below an inclined surface (second surface 32) of the light deflection element 30.

It is worth mentioning that the first lead-out portion 454a of the first connecting belt 45a can be fixed to the fixed base 61a or the upper cover 610a, so that the first bent portion 453a, the first side connecting portion 452a and the first connecting portion 451a located inside the camera module 1 are not affected by external factors, which further increases the resistance of the driving device 60 from the photosensitive component 40. For example, when the first lead-out portion 454a is not fixed, the movement of other devices or equipment connected to the camera module 1 will cause the first lead-out portion 454a to move, and the first bent portion 453a connected to the first lead-out portion 454a will also move, and finally, the resistance generated by the photosensitive component 40 becomes larger.

Furthermore, in some embodiments, due to the improvement in specifications and the increase in functions of the photosensitive component 40, providing the first connecting band 45a only on one side will make the width of the first connecting band 45a too large. Therefore, the connecting circuit board 44 also includes a second connecting band 46a, and the second connecting band 46a is provided on both sides of the chip circuit board 42 opposite to the first connecting band 45a.

In a specific example, the second connecting strip 46a includes a second connecting portion 461a, a second side connecting portion 462a, a second bending portion 463a and a second leading portion 464a connected in sequence, wherein the second connecting portion 461a connects the chip circuit board 42 and the second side connecting portion 462a, and the second bending portion 463a connects the second side connecting portion 462a and the second leading portion 464a. It should be understood that the second connecting portion 461a, the second side connecting portion 462a, the second bending portion 463a and the second leading portion 464a are electrically connected, and the second connecting strip 46a is connected and electrically connected to the chip circuit board 42 through the second connecting portion 461a, so that the chip circuit board 42 can also be electrically connected to an external device or equipment through the second leading portion 464a of the second connecting strip 46a on the opposite side where the first connecting strip 45a is set. It is worth mentioning that in the present application, the second connecting strip 46a can also be a flexible circuit board. Or a hard-soft board, so that the second connecting belt 46 a can be bent to adapt to the space inside the camera module 1 .

In this example, the first connecting band 45a and the second connecting band 46a are arranged around the circumference of the optical lens 10 and the light deflection element 30, making full use of the fact that most of the components of the driving device 60 are arranged on the other side away from the optical lens 10. The camera module 1 has a feature that more space can be utilized on the side where the optical lens 10 is arranged, thereby optimizing the space configuration.

Specifically, the second connection portion 461a extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42, one end of the second connection portion 461a is connected to the chip circuit board 42, and the other end of the second connection portion 461a is bent downward and connected to one end of the second side connection portion 462a. The second side connection portion 462a extends and bends around the circumference of the light turning element 30 and the optical lens 10, so that the second side connection portion 462a is bent from the long side of the camera module 1 to the short side of the camera module 1, and the other end of the second side connection portion 462a is connected to one end of the second bending portion 463a. One end of the second bending portion 463a is connected to the bottom of the other end of the second side connection portion 462a, and the other end of the second bending portion 463a is connected to the second lead-out portion 464a, and the second bending portion 463a is bent and arranged below the second side connection portion 462a. In a specific example, the second bending portion 463a is bent in a horizontal direction, and the second bending portion 463a is disposed below the second side connecting portion 462a in a horizontally bent form.

It should be understood that by setting the second connection belt 46a, the width of the first connection portion 451a of the first connection belt 45a is reduced, so that the resistance of the photosensitive component 40 when moving is reduced. At the same time, the first connection belt 45a and the second connection belt 46a are set on both sides of the chip circuit board 42 to disperse the distribution of resistance. In a specific example, the second connection belt 46a is symmetrically arranged with the first connection belt 45a, which further balances the resistance of the connection circuit board 44 to the drive device 60.

Correspondingly, in the present application, the second bending portion 463a can also be extended and retracted in the height direction to meet the requirement of moving the photosensitive component 40 in the height direction. The second bending portion 463a can also be bent multiple times so that the second bending portion 463a can have a longer extension stroke in the height direction.

It is worth mentioning that, in one example, the second bending portion 463a is also accommodated in the connecting band accommodating cavity 614a of the fixed base 61a to reduce the increase in the length of the camera module 1, and the second connecting band 46a extends from the chip circuit board 42 to the side close to the optical lens 10 (that is, to the side away from the focus driving unit 62a and the anti-shake driving unit 65a), so that part of the second connecting band 46a is bent under the optical lens 10 and the light turning element 30, so that part of the second connecting band 46a is arranged in the connecting band accommodating cavity 614a of the fixed base 61a, thereby optimizing the spatial configuration in the camera module 1 and reducing the size of the camera module 1. In other words, in this example, a portion of the first connecting band 45a (i.e., the first bending portion 453a) and a portion of the second connecting band 46a (i.e., the second bending portion 463a) are bent and arranged in the connecting band accommodating cavity 614a below the optical lens 10 and the light turning element 30, so that the spatial configuration in the camera module 1 is optimized and the length of the camera module 1 is avoided from increasing.

It is worth mentioning that the second lead-out portion 464a of the second connecting belt 46a can also be fixed to the fixed base 61a or the upper cover 610a, so that the second bending portion 463a, the second side connecting portion 462a and the second connecting portion 461a located inside the camera module 1 are not affected by external factors, thereby further increasing the resistance exerted on the driving device 60 by the photosensitive component 40.

Further referring to Figure 10, in another embodiment of the present application, when the light deflecting element 30 is implemented as a parallelogram prism, the optical lens 10 and the photosensitive component 40 are arranged on different sides relative to the light deflecting element 30. For example, in a specific example of the present application, the optical lens 10 is arranged on the first surface 31 of the light deflecting element 30, and the photosensitive component 40 is arranged on the third surface 33 opposite to the first surface 31.

When the driving device 60 is implemented as a chip driving component, it drives the photosensitive component 40 to move relative to the optical lens 10 and the light deflection element 30 to achieve optical focus and/or optical image stabilization. The positions of various components in the driving device 60 change with the position of the photosensitive component 40, that is, the internal structure of the driving device 60 needs to be adjusted accordingly, and the position of the device needs to be adjusted. However, it should be understood that the principles of most devices are similar, so the following only briefly describes the adjustment and improvement.

The optical lens 10 is disposed above the light deflection element 30 and corresponds to the light entrance area 311 of the light deflection element 30, and the photosensitive component 40 is disposed below the light deflection element 30 and corresponds to the light exit area 312 of the light deflection element 30. In this embodiment, along the height direction, the fixed base 61a, the frame 63a and the movable carrier 66a are disposed in sequence, that is, the frame 63a is disposed between the fixed base 61a and the movable carrier 66a, and the movable carrier 66a is located at the lowest position among the three.

In this embodiment, the anti-shake magnetic attraction component is arranged in the movable carrier 66a by insert molding. At least one anti-shake magnet 651a is positioned below the frame 63a to be magnetically attracted to at least one anti-shake magnet 651a, thereby clamping at least three balls 671a disposed between the frame 63a and the movable carrier 66a. Further, the frame cover 630a is fixed to the bottom surface of the frame 63a in the height direction so that the movable carrier 66a is confined in the accommodation cavity formed by the frame cover 630a and the frame 63a.

Furthermore, the movable carrier 66a and the frame 63a extend upward from the bottom of the driving device 60, and the top surfaces of the movable carrier 66a and the frame 63a can be higher or lower than the top surface of the light deflection element 30. When the top surfaces of the movable carrier 66a and the frame 63a are lower than the top surface of the light deflection element 30, the height of the driving device 60 can be lowered.

Figures 11 to 14 show another embodiment of the driving device 60 of the present application. Specifically, Figure 11 shows a cross-sectional view of the camera module 1 along the length direction (i.e., the X-axis direction defined above), the camera module 1 includes the driving device 60 of another embodiment of the present application and the optical lens 10, the light deflection element 30, the filter assembly 50 and the photosensitive assembly 40 disposed in the driving device 60, wherein the photosensitive assembly 40 is disposed on the light-emitting side of the light deflection element 30, the optical lens 10 is disposed on the light-incoming side of the light deflection element 30, and the light emitted by the optical lens 10 is transmitted to the light deflection element 30 at multiple locations. After multiple reflections on the reflective surface, the light is emitted from the light deflection element 30 and reaches the photosensitive component 40. The light deflection element 30 is fixed to the fixed part of the driving device 60, and the photosensitive component 40 is fixed to the movable part of the driving device 60. The optical lens 10 is directly or indirectly fixed to the light deflection element 30, and the filter component 50 is directly or indirectly fixed to the photosensitive component 40. The driving device 60 can drive the photosensitive component 40 to move relative to the light deflection element 30, thereby changing the optical performance of the camera module 1 by moving the chip. Further, Figure 12 shows a cross-sectional view of the camera module 1 along the width direction (i.e., the Y-axis direction defined above); Figure 13 shows an exploded view of the camera module 1, from which the implementation method of the focus function of the camera module 1 can be known; Figure 14 shows an exploded view of a part of the structure of the driving device 60, from which the implementation method of the anti-shake function can be known.

As shown in FIGS. 11 to 14 , the driving device 60 includes a frame 63b, a movable carrier 66b, and an anti-shake driving unit 65b. The movable carrier 66b is movably disposed in the frame 63b, and the anti-shake driving unit 65b is disposed between the frame 63b and the movable carrier 66b, so that the movable carrier 66b is driven by the anti-shake driving unit 65b to move in the horizontal direction relative to the frame 63b. In other words, the driving device 60 is configured to drive the photosensitive component 40 to move, and the photosensitive component 40 is movably disposed at an end of the driving device 40 away from the optical lens 10.

Specifically, as shown in FIG. 11 , FIG. 12 and FIG. 14 , the photosensitive component 40 is fixed to the movable carrier 66 b in a direction facing the light turning element 30 , so that the photosensitive component 40 moves with the movable carrier 66 b to realize the chip anti-shake function. In other words, in a specific example, the photosensitive component 40 is fixed above the movable carrier 66 b. It should be understood that in the present application, the direction of the photosensitive component 40 facing the light turning element 30 means that the photosensitive chip 41 of the photosensitive component 40 faces the light turning element 30, and the photosensitive chip 41 of the photosensitive component 40 faces the light turning element 30 to receive the light emitted by the light turning element 30. In other words, compared with the conventional upright module, the photosensitive component 40 is fixed to the movable carrier 66 b in an inverted state. Among them, the side of the chip circuit board 42 of the photosensitive component 40 facing the light turning element 30 is the front side of the chip circuit board 42 . In a specific example, the movable carrier 66 b is fixed to the front side of the chip circuit board 42 . It is worth mentioning that the movable carrier 66 b can be directly fixed to the chip circuit board 42 by gluing; the movable carrier 66 b can also be indirectly fixed to the chip circuit board 42 by being fixed to the filter element bracket 52 of the filter assembly 50 .

There is an air gap between the movable carrier 66b and the light deflection element 30, and between the movable carrier 66b and the frame 63b, respectively, so that the anti-shake driving unit 65b can drive the movable carrier 66b to move in the horizontal direction (i.e., the direction perpendicular to the optical axis of the optical lens 10) relative to the frame 63b and the light deflection element 30, thereby realizing the chip anti-shake function. It should be understood that in the present application, the horizontal part of the air gap formed between the movable carrier 66b and the light deflection element 30, and between the movable carrier 66b and the frame 63b is suitable for being adjusted in the realization of the chip anti-shake function. In a specific example, the movable carrier 66b is frame-shaped and is arranged around the light deflection element 30.

The frame 63b is arranged on the outside of the movable carrier 66b, and the anti-shake drive unit 65b is arranged between the movable carrier 66b and the frame 63b. The anti-shake drive unit 65b includes at least one anti-shake magnet 651b and at least one anti-shake coil 652b. The at least one anti-shake magnet 651b is fixed to one of the movable carrier 66b and the frame 63b, and the at least one anti-shake coil 652b is fixed to the other of the movable carrier 66b and the frame 63b. The at least one anti-shake magnet 651b and the at least one anti-shake coil 652b are arranged opposite to each other, so that the movable carrier 66b can be driven to move relative to the frame 63b by the magnetic force between the at least one anti-shake magnet 651b and the at least one anti-shake coil 652b to realize the chip anti-shake function.

In a specific example, at least one anti-shake magnet 651b is arranged on the frame 63b, at least one anti-shake coil 652b is arranged on the movable carrier 66b, at least one anti-shake magnet 651b includes a first anti-shake magnet 6511b and a second anti-shake magnet 6512b, at least one anti-shake coil 652b includes a first anti-shake coil 6521b and a second anti-shake coil 6522b, the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are arranged on two adjacent sides of the frame 63b, the first anti-shake coil 6521b and the second anti-shake coil 6522b are arranged on two adjacent sides of the movable carrier 66b, and the first anti-shake coil 6521b is arranged opposite to the first anti-shake magnet 6511b, and the second anti-shake coil 6522b is arranged opposite to the second anti-shake magnet 6512b. In other words, the first anti-shake magnet 6511b and the first anti-shake coil 6521b are arranged between the frame 63b and the movable carrier 66b in the horizontal direction, the second anti-shake magnet 6512b and the second anti-shake coil 6522b are arranged between the frame 63b and the movable carrier 66b in the horizontal direction, and the anti-shake driving unit 65b includes at least one anti-shake magnet 651b and at least one anti-shake coil 652b arranged relatively to each other in the horizontal direction, and the horizontal direction refers to the direction perpendicular to the optical lens 10. In this way, the relative area between the first anti-shake magnet 6511b and the first anti-shake coil 6521b can be made larger, and the relative area between the second anti-shake magnet 6512b and the second anti-shake coil 6522b can be made larger under a smaller lateral dimension (dimension in the length direction and the width direction), thereby providing a larger driving force in the horizontal direction. In particular, at least one anti-shake coil 652b is arranged on the inner side of at least one anti-shake magnet 651b, so that at least one anti-shake coil 652b is arranged on the movable carrier 66b, and the photosensitive component 40 is also fixed to the movable carrier 66b, so that at least one anti-shake coil 652b is electrically connected to the photosensitive component 40, so that the anti-shake circuit board 653b used for electrically conducting at least one anti-shake coil 652b and the photosensitive component 40 can move with the movable carrier 66b, and the anti-shake circuit board 653b can be stationary relative to at least one anti-shake coil 652b and the photosensitive component 40, so that the anti-shake circuit board 653b will not generate resistance to the movement of the photosensitive component 40.

It is worth mentioning that the two adjacent side surfaces where the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are located in the frame 63b are perpendicular to each other, and the two adjacent side surfaces where the first anti-shake coil 6521b and the second anti-shake coil 6522b are located in the movable carrier 66b are perpendicular to each other. In this way, the movable carrier 66b can be driven to move along the first horizontal direction relative to the frame 63b through the magnetic force between the first anti-shake magnet 6511b and the first anti-shake coil 6521b, and the movable carrier 66b can be driven to move along the second horizontal direction relative to the frame 63b through the magnetic force between the second anti-shake magnet 6512b and the second anti-shake coil 6522b. The second horizontal direction and the first horizontal direction are perpendicular to each other. That is, in this example, in the process of realizing chip anti-shake, at least one anti-shake coil 652b (the first anti-shake coil 6521b and the second anti-shake coil 6522b) serves as a mover, and at least one anti-shake magnet 651b (the first anti-shake magnet 6511b and the second anti-shake magnet 6512b) serves as a stator.

Specifically, the frame 63b has an opening toward the light deflection element 30, and the frame 63b includes an integrally formed first frame portion 635b, a second frame portion 637b, and a frame connection portion 636b, wherein the first frame portion 635b and the second frame portion 637b are respectively connected to the two ends of the frame connection portion 636b and are respectively perpendicular to the frame connection portion 636b, so that the frame 63b is in a "Π" shape to avoid the position of the light deflection element 30 and reduce the size of the driving device 60. The first anti-shake magnet 6511b is installed on the inner side surface of the first frame portion 635b, and the inner side surface of the first frame portion 635b has a groove to accommodate the first anti-shake magnet 6511b. The second anti-shake magnet 6512b is installed on the inner side surface of the frame connection portion 636b, and the inner side surface of the frame connection portion 636b also has a groove to accommodate the second anti-shake magnet 6512b. In this way, the size of the driving device 60 and the camera module 1 can be reduced. In other words, the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are installed on two adjacent inner side surfaces of the frame 63b. It should be understood that the "Π" shape of the frame 63b can be obtained when looking down at the frame 63b from the height direction.

Correspondingly, two through holes are also provided on the movable carrier 66b to respectively accommodate the first anti-shake coil 6521b and the second anti-shake coil 6522b, so as to reduce the size of the driving device 60. Specifically, the anti-shake driving unit 65b also includes an anti-shake circuit board 653b, the first anti-shake coil 6521b and the second anti-shake coil 6522b are respectively fixed and electrically connected to the anti-shake circuit board 653b, and the anti-shake circuit board 653b surrounds and is attached to the outer side of the movable carrier 66b, so that the first anti-shake coil 6521b and the second anti-shake coil 6522b are exposed from the two through holes of the movable carrier 66b and are respectively opposite to the first anti-shake magnet 6511b and the second anti-shake magnet 6512b. Among them, the anti-shake circuit board 653b is further electrically connected to the chip circuit board 42, so that the anti-shake driving unit 65b is provided with driving power through the chip circuit board 42 of the photosensitive component 40. The anti-shake circuit board 653b may be a flexible circuit board or a hard-soft board, so that the anti-shake circuit board 653b may be bent around the outer side of the movable carrier 66b. It should be understood that in the above example, the anti-shake circuit board 653b is disposed between the first anti-shake coil 6521b and the first anti-shake magnet 6511b and between the second anti-shake coil 6522b and the second anti-shake magnet 6512b.

It is worth mentioning that in this embodiment, as shown in FIG. 11 and FIG. 12, since the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are arranged on the side of the frame 63b, the bottom surface of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b can be lower than the light turning element. The first anti-shake magnet 6511b and the second anti-shake magnet 6512b extend downward, so that the relative area between the first anti-shake magnet 6511b and the second anti-shake magnet 6512b and the first anti-shake coil 6521b and the second anti-shake coil 6522b can be increased, thereby improving the driving force of the anti-shake driving unit 65b.

In this embodiment, the driving device 60 further includes an anti-shake support portion 67b and an anti-shake magnetic attraction member 650b. The anti-shake support portion 67b is disposed between the frame 63b and the movable carrier 66b so as to maintain an air gap between the frame 63b and the movable carrier 66b, thereby reducing the resistance encountered by the movable carrier 66b when moving relative to the frame 63b. In a specific example, the anti-shake support portion 67b can be implemented as a ball 671b, and the anti-shake support portion 67b includes at least three balls 671b. Specifically, the movable carrier 66b includes a carrier body 662b and a carrier extension portion 663b extending outward from the top of the carrier body 662b, the carrier extension portion 663b is extended to the top of the frame 63b, and at least three balls 671b are disposed between the frame 63b and the carrier extension portion 663b of the movable carrier 66b along the height direction, so as to maintain a fixed gap between the frame 63b and the movable carrier 66b in the height direction. Specifically, the at least three balls 671b are disposed above the frame 63b and below the carrier extension portion 663b. It should be understood that the anti-shake support portion 67b can also be implemented as other elements such as a spring or a slider.

The anti-shake magnetic component 650b is fixed to the movable carrier 66b and is arranged above at least one anti-shake magnet 651b (the first anti-shake magnet 6511b and/or the second anti-shake magnet 6512b). The anti-shake magnetic component 650b is made of a material suitable for being attracted by a magnet, and is magnetically attracted to at least one anti-shake magnet 651b so that the movable carrier 66b is adsorbed toward the frame 63b in the height direction, and the movable carrier 66b and the frame 63b clamp at least three balls 671b in the height direction. It should be understood that the anti-shake magnetic component 650b can be fixed to the movable carrier 66b by insert molding or bonding. For example, the anti-shake magnetic component 650b is fixed in the carrier extension portion 663b of the movable carrier 66b by insert molding.

Furthermore, in order to limit the moving direction of the ball 671b, the frame 63b further includes at least three first ball grooves 634b formed on the top surface of the frame 63b, and the movable carrier 66b further includes at least three second ball grooves 661b formed on the bottom surface of the carrier extension 663b. The position of the first ball groove 634b corresponds to the position of the second ball groove 661b, and the extension direction of the first ball groove 634b and the extension direction of the second ball groove 661b are perpendicular to each other, forming a "cross" shape. The bottom and top of the ball 671b are respectively accommodated in the first ball groove 634b and the second ball groove 661b, and are respectively allowed to roll along the first ball groove 634b and the second ball groove 661b.

In a specific example, as shown in Figure 14, the anti-shake support portion 67b includes four ball bearings 671b, four first ball bearing grooves 634b are formed at the four corners of the top surface of the frame 63b, four second ball bearing grooves 661b corresponding to the four first ball bearing grooves 634b are formed at the four corners of the bottom surface of the carrier extension portion 663b, and the anti-shake magnetic suction component 650b fixed in the extension portion of the movable carrier 66b is magnetically attracted to the first anti-shake magnet 6511b and the second anti-shake magnet 6512b, so that the four ball bearings 671b are respectively clamped between the four corners of the frame 63b and the four corners of the movable carrier 66b.

It is worth mentioning that the driving device 60 also includes a frame cover 630b, which is fixed to the top surface of the frame 63b in the height direction so that the movable carrier 66b is confined in the accommodating cavity formed by the frame cover 630b and the frame 63b. It should be understood that during the falling process, the magnetic attraction force between the anti-shake magnetic suction member 650b and the anti-shake magnet 651b is difficult to maintain the positional relationship between the movable carrier 66b and the frame 63b. After the movable carrier 66b has a large displacement relative to the frame 63b, the ball 671b will be separated from the first ball groove 634b and the second ball groove 661b. Therefore, in the present application, a frame cover 630b is further provided to limit the moving stroke of the movable carrier 66b in the height direction through the frame cover 630b, thereby preventing the ball 671b from falling off. Specifically, the carrier extension portion 663b of the movable carrier 66b overlaps with the frame cover 630b in the height direction. When the movable carrier 66b moves along the height direction toward a direction away from the light deflection element 30, the carrier extension portion 663b of the movable carrier 66b abuts against the frame cover 630b, thereby confining the movable carrier 66b in the accommodating cavity formed by the frame cover 630b and the frame 63b.

Furthermore, the driving device 60 can also realize the chip focusing function. Specifically, as shown in FIG. 12 and FIG. 13, the driving device 60 also includes a fixed base 61b and a focus driving unit 62b disposed between the fixed base 61b and the frame 63b. The frame 63b is movably disposed in the fixed base 61b, and the focus driving unit 62b is disposed between the fixed base 61b and the frame 63b, so that the frame 63b is driven by the focus driving unit 62b to move relative to the fixed base 61b in the height direction. Since the frame 63b is moved, the movable carrier 66b, the anti-shake driving unit 65b, the anti-shake support unit 67b and the anti-shake magnetic suction member 650b disposed in the frame 63b also move with the movement of the frame 63b, and then the photosensitive component 40 fixed to the movable carrier 66b also moves with the movement of the frame 63b, thereby realizing the chip focusing function.

The driving device 60 also includes an upper cover 610b fixed to the fixed base 61b, and the upper cover 610b and the fixed base 61b form a receiving chamber to accommodate the focus driving unit 62b, the frame 63b, the frame cover 630b, the anti-shake driving unit 65b and the movable carrier 66b. The upper cover 610b has a lens opening 611b, so that the optical lens 10 can extend from the driving device 60 through the lens opening 611b. There is an air gap between the frame 63b and the fixed base 61b, so that the focus driving unit 62b can drive the frame 63b to move relative to the fixed base 61b in the height direction, thereby realizing the chip focusing function. It should be understood that in the present application, the part of the air gap formed between the frame 63b and the fixed base 61b in the height direction is suitable for being adjusted in the realization of the chip focusing function.

14, the fixed base 61b includes a base body 611b, a bearing portion 613b and a focus fixing portion 612b, wherein the bearing portion 613b is fixed to the middle of the base body 611b, and the focus fixing portion 612b is fixed to one side of the base body 611b, specifically, the focus fixing portion 612b is fixed to the long side of the base body 611b. It should be understood that the bearing portion 613b and the focus fixing portion 612b can be fixed to the base body 611b by bonding or integral molding.

The carrying portion 613b has a carrying cavity for mounting the light deflection element 30. In other words, the light deflection element 30 is mounted on the carrying portion 613b, and the shape of the carrying cavity of the carrying portion 613b is adapted to the shape of the light deflection element 30. For example, when the light deflection element 30 is implemented as a trapezoidal prism, the carrying cavity of the carrying portion 613b has a size that gradually decreases from the top to the bottom.

The focus driving unit 62b is arranged between the frame 63b and the focus fixing unit 612b of the fixed base 61b. The focus driving unit 62b includes a pair of focus magnets 621b and a pair of focus coils 622b. The focus magnet 621b is fixed to one of the frame 63b and the focus fixing unit 612b, and the focus coil 622b is fixed to the other of the frame 63b and the focus fixing unit 612b. The focus magnet 621b and the focus coil 622b are arranged relatively to each other, so that the magnetic force between the focus magnet 621b and the focus coil 622b can drive the frame 63b to move in the height direction relative to the fixed base 61b to realize the chip focusing function.

In a specific example, the focus magnet 621b is disposed on the side of the frame 63b, the focus coil 622b is disposed on the focus fixing portion 612b of the fixed base 61b, and the focus coil 622b is disposed opposite to the focus magnet 621b. In other words, the focus coil 622b and the focus magnet 621b are disposed between the frame 63b and the focus fixing portion 612b of the fixed base 61b in the horizontal direction, and the focus drive unit 62b includes the focus coil 622b and the focus magnet 621b disposed opposite to each other in the horizontal direction, and the horizontal direction refers to the direction perpendicular to the optical lens 10. In this way, a larger driving force in the height direction can be provided with a smaller lateral dimension (dimensions in the length direction and the width direction).

It should be understood that, in the process of implementing chip focusing, the focusing coil 622b fixed to the focusing fixing part 612b drives the focusing magnet 621b to move in the height direction relative to the focusing coil 622b, so that the frame 63b fixed to the focusing magnet 621b moves in the height direction along with the movement of the focusing magnet 621b. That is, in this example, in the process of implementing chip focusing, the focusing magnet 621b acts as a mover and the focusing coil 622b acts as a stator.

Furthermore, the focus driving part 62b also includes a focus circuit board 623b, and the focus coil 622b is fixed and electrically connected to the focus circuit board 623b. The focus circuit board 623b is fixed to the focus fixing part 612b, so that the focus coil 622b is indirectly fixed to the focus fixing part 612b through the focus circuit board 623b. In a specific example, the focus circuit board 623b is attached to the outer side surface of the focus fixing part 612b, and a through hole is provided on the focus fixing part 612b to expose the focus coil 622b and face the focus magnet 621b. The through hole on the focus fixing part 612b accommodates the focus coil 622b, so that the lateral size of the driving device 60 can be reduced. It should be understood that the outer side surface of the focus fixing part 612b refers to the side of the focus fixing part 612b away from the frame 63b. It is worth mentioning that the focusing circuit board 623b is further electrically connected to the chip circuit board 42. The focusing circuit board 623b can be a flexible circuit board or a soft-hard combination board. In this way, the focusing circuit board 623b can be arranged in the driving device 60 in a bent state so that the focusing circuit board 623b can be extended to a position that is convenient for electrical connection with the chip circuit board 42.

Accordingly, the focus magnet 621b is installed on the outer side surface of the frame 63b so that a small distance can be maintained between the focus magnet 621b and the focus coil 622b, thereby enhancing the magnetic force between the focus magnet 621b and the focus coil 622b. Specifically, the focus magnet 621b is installed on the outer side surface of the second frame portion 637b, and the outer side surface of the second frame portion 637b has a groove to accommodate the focus magnet 621b, so that the size of the drive device 60 and the camera module 1 can be reduced. It should be understood that the outer side surface of the frame 63b refers to the side of the frame 63b facing the fixed base 61b or the upper cover 610b, and the outer side surface of the second frame portion 637b refers to the side of the second frame portion 637b facing the focus fixing portion 612b.

In the driving device 60 shown in FIGS. 11 to 14 , the first frame portion 635b and the frame connecting portion 636b are respectively used to install the first The anti-shake magnet 6511b and the second anti-shake magnet 6512b, the second frame portion 637b is used to install the focus magnet 621b, the frame 63b includes an anti-shake frame 633b and a focus frame 631b, the first frame portion 635b and the frame connecting portion 636b form an "L"-shaped anti-shake frame 633b, the second frame portion 637b forms a focus frame 631b, and the anti-shake frame 633b and the focus frame 631b are connected by integral molding. It is worth mentioning that the focusing magnet 621b and at least one anti-shake magnet 651b (the first anti-shake magnet 6511b and the second anti-shake magnet 6512b) are both fixed on the side of the frame 63b, wherein the focusing magnet 621b is fixed on the outer side of the frame 63b, and at least one anti-shake magnet 651b is fixed on the inner side of the frame 63b. In particular, at least one anti-shake magnet 651b is not arranged on the top surface of the frame 63b, so that the lateral size of the driving device 60 is relatively small. It should be understood that in this embodiment, the first anti-shake coil 6521b and the second anti-shake coil 6522b are located on the inner side of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b, and the focus coil 622b is located on the outer side of the focus magnet 621b. In this way, the first anti-shake coil 6521b and the second anti-shake coil 6522b can be directly electrically connected to the chip circuit board 42 of the photosensitive component 40 from the inside, while the focus coil 622b is electrically connected to the photosensitive component 40 from the outside, thereby optimizing the electrical connection setting method of the camera module 1.

It is worth mentioning that in this embodiment, as shown in Fig. 12, since the focus magnet 621b is disposed on the side of the focus fixing portion 612b of the fixing base 61b, the bottom surface of the focus magnet 621b can be lower than the top surface of the light turning element 30. The focus magnet 621b extends downward, so that the relative area between the focus magnet 621b and the focus coil 622b can be increased, thereby improving the driving force of the focus driving portion 62b.

It is worth mentioning that, in this embodiment, the focus magnet 621 b , the first anti-shake magnet 6511 b and the second anti-shake magnet 6512 b are arranged on the peripheral side of the light turning element 30 .

In this embodiment, the driving device 60 also includes a focusing guide portion 64b and a focusing magnetic suction member 620b. The focusing guide portion 64b is arranged between the frame 63b and the fixed base 61b so as to maintain an air gap between the frame 63b and the fixed base 61b, thereby reducing the resistance encountered by the frame 63b when it moves relative to the fixed base 61b. In a specific example, the focusing guide portion 64b can be implemented as a guide rod 641b, and the focusing guide portion 64b includes two guide rods 641b. Specifically, the two guide rods 641b are vertically arranged between the second frame portion 637b of the frame 63b and the focusing fixing portion 612b of the fixed base 61b, so as to maintain a fixed gap between the frame 63b and the fixed base 61b in the horizontal direction. Furthermore, in this embodiment, two guide rods 641b are respectively disposed on both sides of the focus driving portion 62b, and the two guide rods 641b have the same size to prevent the frame 63b and the focus fixing portion 612b from tilting.

The focusing magnetic suction piece 620b is fixed to the focusing fixing part 612b of the fixed base 61b by being attached to the back of the focusing circuit board 623b, so that in the width direction, the focusing magnet 621b, the focusing coil 622b, the focusing circuit board 623b and the focusing magnetic suction piece 620b are arranged in sequence. Among them, the side of the focusing circuit board 623b on which the focusing coil 622b is arranged is the front side of the focusing circuit board 623b, and the other opposite side is the back side of the focusing circuit board 623b. The focusing magnetic suction piece 620b is made of a material suitable for being attracted by a magnet, and it is magnetically attracted to the focusing magnet 621b so that the frame 63b is adsorbed to the focusing fixing part 612b of the fixed base 61b in the width direction. The frame 63b and the focusing fixing part 612b of the fixed base 61b clamp two guide rods 641b in the width direction. The focusing magnetic suction piece 620b can be a material containing iron.

In other words, the focus guide portion 64b is arranged between the second frame portion 637b of the frame 63b and the focus fixing portion 612b of the fixed base 61b, the focus magnetic suction component 620b is fixed to the focus fixing portion 612b, and the focus magnetic suction component 620b and the focus magnet 621b are magnetically attracted to each other so that the focus guide portion 64b is clamped between the second frame portion 637b of the frame 63b and the focus fixing portion 612b of the fixed base 61b.

In a specific example, two first guide rails 6123b extending in the height direction are formed on the inner side surface of the focus fixing part 612b opposite to the frame 63b, and two second guide rails 632b extending in the height direction are formed on the outer side surface of the frame 63b opposite to the focus fixing part 612b (that is, the outer side surface of the second frame part 637b), and the two first guide rails 6123b and the two second guide rails 632b are respectively arranged. The two guide rods 641b are respectively arranged between the two first guide rails 6123b and the two second guide rails 632b, and are clamped between the frame 63b and the focus fixing part 612b under the magnetic attraction between the focus magnetic attraction member 620b and the focus magnet 621b.

It is worth mentioning that in one example of the present application, the two guide rods 641b may not be fixed, and they are only clamped by the frame 63b and the focus fixing part 612b; in another example of the present application, the positions of the two guide rods 641b may also be fixed, for example, they may be fixed to the fixed base 61b by fixing the bottom end of the guide rod 641b to the fixed base 61b and/or fixing the top end of the guide rod 641b to the upper cover 610b, or, the two guide rods 641b are restricted between the upper cover 610b and the fixed base 61b only by the snap fit between the upper cover 610b and the fixed base 61b.

It is worth mentioning that in the above embodiment, since the light deflection element 30 disposed between the optical lens 10 and the photosensitive component 40 is relatively long, in order to reduce the overall size of the camera module 1, the frame 63b has an opening in the direction toward the light deflection element 30, so that the frame 63b is disposed around the light deflection element 30 in a "Π" shape, and therefore, only three sides of the frame 63b can be provided with the first anti-shake magnet 6511b, the second anti-shake magnet 6512b and the focus magnet 621b. The first anti-shake magnet 6511b and the second anti-shake magnet 6512b need to be disposed perpendicularly to each other to achieve translation in two perpendicular directions, and therefore, one of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b needs to be disposed on the short side of the driving device 60, and the other of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b and the focus magnet 621b are disposed on the two opposite long sides of the driving device 60, respectively.

Specifically, the first anti-shake magnet 6511b is installed on the inner side of the first frame portion 635b located on the long side of the driving device 60, the second anti-shake magnet 6512b is installed on the inner side of the frame connection portion 636b located on the short side of the driving device 60, and the focus magnet 621b is installed on the outer side of the second frame portion 637b located on the long side of the driving device 60. The focus magnet 621b, the first anti-shake magnet 6511b, and the second anti-shake magnet 6512b are flat rectangular parallelepipeds, and the largest side of the focus magnet 621b is parallel to the largest side of the first anti-shake magnet 6511b, and the largest side of the focus magnet 621b is perpendicular to the largest side of the second anti-shake magnet 6512b. Correspondingly, the focus coil 622b is parallel to the first anti-shake coil 6521b, and the focus coil 622b is perpendicular to the second anti-shake coil 6522b.

Further, in one example, the magnetic pole direction of the focus magnet 621b is perpendicular to the magnetic pole direction of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b, so that the driving direction of the focus drive unit 62b is perpendicular to the driving direction of the anti-shake drive unit 65b. Wherein, in the present application, the magnetic pole direction of the magnet refers to the direction in which the S pole of the magnet points to the N pole. Correspondingly, the focus coil 622b, the first anti-shake coil 6521b and the second anti-shake coil 6522b are all runway-type coils, wherein the winding plane of the focus coil 622b and the winding plane of the first anti-shake coil 6521b are parallel to each other, and the winding plane of the focus coil 622b and the winding plane of the second anti-shake coil 6522b are perpendicular to each other.

It should be understood that in this embodiment, since the focusing magnet 621b and the first anti-shake magnet 6511b have different size specifications, the focusing magnet 621b and the first anti-shake magnet 6511b are not symmetrically arranged. Accordingly, in one example, in the width direction, the optical lens 10, the light turning element 30 and the photosensitive component 40 are eccentrically arranged in the driving device 60.

11, 13 and 14, the connection circuit board 44 includes a first connection belt 45b, which includes a first connection portion 451b, a first side connection portion 452b, a first bending portion 453b and a first lead-out portion 454b connected in sequence, wherein the first connection portion 451b connects the chip circuit board 42 and the first side connection portion 452b, and the first bending portion 453b connects the first side connection portion 452b and the first lead-out portion 454b. It should be understood that the first connection portion 451b, the first side connection portion 452b, the first bending portion 453b and the first lead-out portion 454b are electrically connected, and the first connection belt 45b is connected and electrically connected to the chip circuit board 42 through the first connection portion 451b, so that the chip circuit board 42 can be electrically connected to an external device or equipment through the first lead-out portion 454b of the first connection belt 45b. It is worth mentioning that in the present application, the first connecting belt 45 b can be a flexible circuit board or a soft-hard combination board, so that the first connecting belt 45 b can be bent to adapt to the space inside the camera module 1.

Specifically, the first connection portion 451b extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42, one end of the first connection portion 451b is connected to the chip circuit board 42, and the other end of the first connection portion 451b is bent downward and connected to one end of the first side connection portion 452b. The first side connection portion 452b extends and bends around the circumference of the light turning element 30 and the optical lens 10, so that the first side connection portion 452b is bent from the long side of the camera module 1 to the short side of the camera module 1, and the other end of the first side connection portion 452b is connected to one end of the first bending portion 453b. One end of the first bending portion 453b is connected to the bottom of the other end of the first side connection portion 452b, and the other end of the first bending portion 453b is connected to the first lead-out portion 454b, and the first bending portion 453b is bent and arranged below the first side connection portion 452b. In a specific example, the first bending portion 453b is bent in a horizontal direction, and the first bending portion 453b is disposed below the first side connecting portion 452b in a horizontally bent form. The directions shown in the drawings in the present application are as follows: in the present application, the direction of the optical lens 10 relative to the light deflection element 30 is considered as the upper direction, and the opposite direction is considered as the lower direction. In other words, the light deflection element 30 is below the optical lens 10 .

It should be understood that, by setting the first side connection portion 452b, the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the horizontal direction is reduced, and by setting the first bending portion 453b, the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the height direction can be reduced. In particular, in the present application, the driving device 60 drives the photosensitive component 40 to move in the height direction to a stroke of at least 2 mm, and the first bending portion 453b can be extended in the height direction to meet the requirements of the photosensitive component 40 moving in the height direction. Furthermore, the first bending portion 453b can be bent multiple times so that the first bending portion 453b can have a longer extension stroke in the height direction.

It is worth mentioning that in order to design the size of the camera module 1 to be smaller, in the present application, the fixed base 61b also includes a connecting belt accommodating cavity 614b formed between the base body 611b and the supporting portion 613b, and the connecting belt accommodating cavity 614b is arranged on the side of the fixed base 61b close to the optical lens 10, and the connecting belt accommodating cavity 614b is located below the optical lens 10 and the light turning element 30, and the first bending portion 453b is accommodated in the connecting belt accommodating cavity 614b, thereby avoiding an increase in the length of the camera module 1. The first connecting strip 45b extends from the chip circuit board 42 to the side close to the optical lens 10 (i.e., to the side away from the focus driving unit 62b and the anti-shake driving unit 65b), so that part of the first connecting strip 45b is bent below the optical lens 10 and the light deflection element 30, so that part of the first connecting strip 45b is arranged in the connecting strip accommodating cavity 614b of the fixed base 61b, optimizing the spatial configuration in the camera module 1, thereby reducing the size of the camera module 1. It is worth mentioning that the bottom of the light deflection element 30 refers to the bottom of the top surface of the light deflection element 30, that is, the bottom of the first surface 31 of the light deflection element 30. Further, the bottom of the light deflection element 30 further refers to the bottom of the second surface 32 of the light deflection element 30, part of the first connecting strip 45a is bent below an inclined surface (the second surface 32) of the light deflection element 30, and the connecting strip accommodating cavity 614a is located below an inclined surface (the second surface 32) of the light deflection element 30.

It is worth mentioning that the first lead-out portion 454b of the first connecting belt 45b can be fixed to the fixed base 61b or the upper cover 610b, so that the first bent portion 453b, the first side connecting portion 452b and the first connecting portion 451b located inside the camera module 1 are not affected by external factors, which further increases the resistance of the driving device 60 from the photosensitive component 40. For example, when the first lead-out portion 454b is not fixed, the movement of other devices or equipment connected to the camera module 1 will cause the first lead-out portion 454b to move, and the first bent portion 453b connected to the first lead-out portion 454b will also move, and finally, the resistance generated by the photosensitive component 40 becomes larger.

Furthermore, in some embodiments, due to the improvement in specifications and the increase in functions of the photosensitive component 40, providing the first connecting band 45b only on one side will make the width of the first connecting band 45b too large. Therefore, the connecting circuit board 44 also includes a second connecting band 46b, and the second connecting band 46b is provided on both sides of the chip circuit board 42 opposite to the first connecting band 45b.

In a specific example, the second connecting strip 46b includes a second connecting portion 461b and a second side connecting portion 462b, wherein the second connecting portion 461b connects the chip circuit board 42 and the second side connecting portion 462b. It should be understood that the second connecting portion 461b and the second side connecting portion 462b are electrically connected, and the second connecting strip 46b is connected and electrically connected to the chip circuit board 42 through the second connecting portion 461b, so that the chip circuit board 42 can be electrically connected to other components through the second connecting strip 46b on the opposite side where the first connecting strip 45b is set. It is worth mentioning that in the present application, the second connecting strip 46b can also be a flexible circuit board or a soft-hard combination board, so that the second connecting strip 46b can be bent to adapt to the space inside the camera module 1.

In this example, the first connecting belt 45b and the second connecting belt 46b are arranged around the optical lens 10 and the light deflection element 30, making full use of the fact that most of the components of the driving device 60 are arranged on the other side away from the optical lens 10. The camera module 1 has a feature that more space can be used on the side where the optical lens 10 is arranged, thereby optimizing the space configuration.

Specifically, the second connection portion 461b extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42, one end of the second connection portion 461b is connected to the chip circuit board 42, and the other end of the second connection portion 461b is bent downward and connected to one end of the second side connection portion 462b. The second side connection portion 462b extends and bends around the periphery of the light turning element 30 and the optical lens 10, so that the second side connection portion 462b is bent from the long side of the camera module 1 to the short side of the camera module 1, and the other end of the second side connection portion 462b is fixed and electrically connected to the other end of the first side connection portion 452b, so that the second connection band 46b is electrically connected to an external device or equipment through the first bending portion 453b and the first lead-out portion 454b of the first connection band 45b. catch.

It should be understood that by providing the second connecting strip 46b, the width of the first connecting portion 451b of the first connecting strip 45b is reduced, so that the resistance encountered by the photosensitive component 40 during movement is reduced. At the same time, providing the first connecting strip 45b and the second connecting strip 46b on both sides of the chip circuit board 42 can also disperse the distribution of resistance.

In a specific example, the second connection portion 461b and the second side connection portion 462b of the second connection belt 46b are symmetrically arranged with the first connection portion 451b and the first side connection portion 452b of the first connection belt 45b, further balancing the resistance brought to the driving device 60 by the connecting circuit board 44.

The above describes the structure of the drive device 60 and the camera module 1 when the photosensitive component 40 and the optical lens 10 are located on the same side of the light deflection element 30 in the present application. Furthermore, in the present application, the photosensitive component 40 and the optical lens 10 can also be located on both sides of the light deflection element 30, and accordingly, the internal structure of the drive device 60 needs to be adjusted accordingly, and the position of the device needs to be adjusted. However, it should be understood that the principles of most devices are similar, so the following only briefly describes the adjustment and improvement.

As shown in FIG. 2C and FIG. 15 , the optical lens 10 is disposed above the light deflection element 30 and corresponds to the light entrance area 311 of the light deflection element 30, and the photosensitive component 40 is disposed below the light deflection element 30 and corresponds to the light exit area 312 of the light deflection element 30. In this embodiment, the anti-shake magnetic suction member 650b is disposed in the movable carrier 66b by insert molding, and the anti-shake magnetic suction member 650b is disposed below at least one anti-shake magnet 651b to be magnetically attracted to at least one anti-shake magnet 651b, thereby clamping at least three balls 671b disposed between the frame 63b and the movable carrier 66b. Furthermore, the frame cover 630b is fixed to the bottom surface of the frame 63b in the height direction so that the movable carrier 66b is confined in the accommodating cavity formed by the frame cover 630b and the frame 63b.

In the embodiments shown in Figures 2C and 15, the movable carrier 66b and the frame 63b extend upward from the bottom of the driving device 60, and the top surfaces of the movable carrier 66b and the frame 63b can be higher or lower than the top surface of the light turning element 30. When the top surfaces of the movable carrier 66b and the frame 63b are lower than the top surface of the light turning element 30, the height of the driving device 60 can be lowered.

Furthermore, mobile phones, tablets or other electronic devices currently on the market are usually equipped with multiple camera modules to form an array module, and the multiple camera modules are usually arranged close to each other. However, since the camera modules usually use voice coil motors driven by electromagnetic force, adjacent motors will generate magnetic interference when they are arranged close to each other. Therefore, the present application further provides a new array module 100 design in order to solve the above-mentioned problem.

The array module 100 includes the camera module 1 shown in the above-mentioned Figures 1 to 16 of the present application and a first sub-module 102 arranged adjacent to the camera module 1. The camera module 1 and the first sub-module 102 are arranged in the same direction to be suitable for photographing the same subject. The first sub-module 102 includes a first motor 1021, a first lens 1022 installed in the first motor 1021, and a first connection circuit board 1023 for providing power to the first sub-module 102. The first motor 1021 can be a voice coil motor driven by electromagnetic force.

The first sub-module 102 also includes a first photosensitive component, which includes a first chip circuit board and a first photosensitive chip electrically connected to the first chip circuit board and a plurality of electronic components. The first photosensitive chip is used to receive the light focused by the first lens 1022 and form an image. The first connecting circuit board 1023 is electrically connected to the first chip circuit board of the first photosensitive component to provide a driving power source for the second photosensitive component. The first motor 1021 is fixed to the first photosensitive component and electrically connected to the first chip circuit board, thereby providing a driving power source to the first motor 1021 through the first chip circuit board.

In the present application, since the light deflection element 30 is in the shape of an elongated strip, the driving device 60 and the camera module 1 including the driving device 60 are also in the shape of an elongated strip, therefore, in the length direction, the optical lens 10 of the camera module 1 is eccentrically arranged in the driving device 60, and the driving unit containing a magnet in the driving device 60 (the driving unit includes the front focus driving unit 62a (62b) and the anti-shake driving unit 65a (65b)) is eccentrically arranged on the other side of the driving device 60. That is, along the length direction, the camera module 1 includes a first area 1011 and a second area 1012 which are arranged opposite to each other along the length direction, wherein the optical lens 10 is arranged in the first area 1011 of the camera module 1, and the second area 1012 is arranged on the other side of the camera module 1 away from the first area 1011. The optical lens 10 is arranged away from the second area 1012, and the driving unit including a magnet in the driving device 60 (the driving unit includes the front focusing driving unit 62a (62b) and the anti-shake driving unit 65a (65b)) is arranged in the second area 1012 of the camera module 1.

In other words, the camera module includes a first area 1011 and a second area 1012 which are arranged opposite to each other along the length direction, the camera module 1 includes an optical lens 10 and a driving device 60, the optical lens 10 is eccentrically arranged in the driving device 60, the optical lens 10 is arranged in the first area 1011, and the driving unit including a magnet in the driving device 60 is arranged in the second area 1012. That is, the focus magnet 621a (621b) and at least one anti-shake magnet 651a (651b) is eccentrically arranged in the second area 1012 of the camera module 1.

Correspondingly, as shown in FIG16 , the first submodule 10 is disposed on the peripheral side of the first region 1011 of the camera module 1, and the first submodule 102 is disposed close to the first region 1011 of the camera module 1, so that the first submodule 102 is away from the second region 1012 of the camera module 1, so that the magnetic interference of the first submodule 102 with the driving device 60 of the camera module 1 can be reduced. The first submodule 102 is disposed adjacent to the first region 1011 of the camera module 1, which can reduce the interference of the magnet included in the driving part of the camera module 1 on the first submodule 102, especially, when the first motor 1021 is implemented as a voice coil motor (VCM), the first submodule 102 is disposed adjacent to the first region 1011 of the camera module 1, so that the magnetic interference between the driving device 60 and the first motor 1021 can be reduced.

Further, the camera module 1 also includes a connecting circuit board 44 for providing power to the camera module 1, as shown in Figures 11, 14 and 16, and the connecting circuit board 44 extends outward along the length direction of the camera module 1. Specifically, the camera module 1 is in the shape of an elongated strip, having two long sides and two short sides, one of which is closer to the first area 1011 of the camera module 1. In a specific example, the two short sides are parallel to each other, the two long sides are parallel to each other, and the long sides are perpendicular to the short sides. The connecting circuit board 44 of the camera module 1 extends outward from the short side of the camera module 1 closer to the first area 1011, so that further, the first sub-module 102 is adjacently arranged on one of the long sides of the camera module 1, so that the connecting circuit board 44 of the camera module 1 will not interfere with the installation of the first sub-module 102, so that the first sub-module 102 and the camera module 1 can be arranged closer, thereby reducing the lateral size of the array module 100. Correspondingly, the first connecting circuit board 1023 of the first sub-module 102 extends outward from one side of the first sub-module 102 that is not close to the camera module 1, and the extension direction of the first connecting circuit board 1023 can be parallel to the extension direction of the connecting circuit board 44 of the camera module 1.

It is worth mentioning that the array module 100 may further include a module bracket, and the first sub-module 102 and the camera module 1 are installed in the module bracket to maintain the relative position between the first sub-module 102 and the camera module 1.

It should be understood that in this embodiment, the optical lens 10 of the camera module 1 has a long focal length, that is, the optical lens 10 is a telephoto lens, and the camera module 1 can be a telephoto camera module. Correspondingly, the first sub-module 102 can be a wide-angle camera module, and the first lens 1022 can be a wide-angle lens, so that the first sub-module 102 can form a wide-angle + telephoto photography combination with the camera module 1.

It should be understood that in this embodiment, since the optical lens 10 of the camera module 1 is vertically arranged in the driving device 60, the optical axis of the first lens 1022 of the first sub-module 102 can be parallel to the optical axis of the optical lens 10 of the camera module 1.

Continuing to refer to FIG. 16 , the array module 100 may further include a second submodule 103, which is adjacently arranged on the other long side of the camera module 1 and close to the first area 1011 of the camera module 1. The second submodule 103 is arranged in the same direction as the camera module 1 to be suitable for photographing the same subject. In a specific example, the first submodule 102 and the second submodule 103 are symmetrically arranged around the first area 1011 of the camera module 1.

The second submodule 103 includes a second motor 1031, a second lens 1032 installed in the second motor 1031, and a second connection circuit board 1033 for providing power to the second submodule 103. The second motor 1031 can be a voice coil motor driven by electromagnetic force. The second submodule 103 is arranged close to the first area 1011 of the camera module 1, so that the second submodule 103 is arranged away from the second area 1012 of the camera module 1, so that the magnetic interference of the second motor 1031 of the second submodule 103 by the driving device 60 of the camera module 1 can be reduced. Further, the second submodule 103 is arranged on the other long side of the camera module 1, so that the connection circuit board 44 of the camera module 1 will not interfere with the installation of the second submodule 103, so that the second submodule 103 and the camera module 1 can be arranged closer, thereby reducing the lateral size of the array module 100. Correspondingly, the second connecting circuit board 1033 of the second sub-module 103 extends outward from one side of the second sub-module 103 that is not close to the camera module 1, and the extension direction of the second connecting circuit board 1033 can be perpendicular to the extension direction of the connecting circuit board 44 of the camera module 1.

The second sub-module 103 also includes a second photosensitive component, which includes a second chip circuit board and a second photosensitive chip electrically connected to the second chip circuit board and a plurality of electronic components. The second photosensitive chip is used to receive the light converged by the second lens 1032 and form an image. The second connecting circuit board 1033 is electrically connected to the second chip circuit board of the second photosensitive component to provide a driving power supply for the second photosensitive component. The second motor 1031 is fixed to the second photosensitive component and electrically connected to the second chip circuit board, thereby providing a driving power supply to the second motor 1021 through the second chip circuit board. It is worth mentioning that the second sub-module 103 can also be installed in the module bracket to maintain the relative position between the second sub-module 103 and the camera module 1 and the first sub-module 102.

It should be understood that in this embodiment, the second sub-module 103 can be a wide-angle camera module or a telephoto camera module to cooperate with the imaging of the camera module 1 and the first sub-module 102. For example, the second sub-module 103 can be a telephoto camera module with a focal length smaller than that of the camera module 1, so that the zoom of the array module 100 can be smoother.

It should be understood that in this embodiment, the optical axis of the second lens 1032 of the second sub-module 103 can be parallel to the optical axis of the optical lens 10 of the camera module 1 and the optical axis of the first lens 1022 of the first sub-module 102 .

It should be understood that in the present application, the array module 100 may also include more modules, and the present application merely exemplarily points out the arrangement of two and three modules.

FIG. 17 to FIG. 23B show a camera module 1′ according to some embodiments of the present application, wherein the camera module 1′ comprises an optical lens 10′, a light deflection element 30′, a photosensitive component 40′ and a driving device 60′. The light deflection element 30′ is disposed between the optical lens 10′ and the photosensitive component 40′, so that the light incident on the optical lens 10′ is reflected at least once in the light deflection element 30′ before reaching the photosensitive component 40′. The light deflection element 30′ folds the light emitted from the optical lens 10′ and guides it to the photosensitive component 40′, thereby imaging through the photosensitive component 40′ to obtain image information. It is worth mentioning that the light deflection element 30′ is in the shape of a long strip, so that the light can be reflected multiple times in the light deflection element 30′, thereby folding the light path multiple times. In the present application, the position of one or more components among the optical lens 10’, the light deflection element 30’ or the photosensitive component 40’ in the camera module 1’ can be adjusted to achieve the optical focus and/or optical image stabilization function of the camera module 1’. For example, the driving device 60’ can be configured to drive one or more components among the optical lens 10’, the light deflection element 30’ or the photosensitive component 40’ to move.

The optical lens 10' has an optical axis, and the light incident on the light deflection element 30' along the optical axis direction is reflected at least once in the light deflection element 30', that is, the light is deflected from propagating along the optical axis direction to propagating in another direction roughly orthogonal to the optical axis, and finally emitted along the optical axis direction to reach the photosensitive component 40'. For the convenience of description, a rectangular coordinate system is established, the Z axis approaches the optical axis direction of the optical lens 10' or the direction parallel to the optical axis of the optical lens 10', the Z axis direction is perpendicular to the plane where the X axis direction and the Y axis direction are located, the X axis direction and the Y axis direction are perpendicular to each other, the XOY plane where the X axis direction and the Y axis direction are located is also called the plane where the horizontal direction is located, and the horizontal direction is the direction perpendicular to the optical axis of the optical lens 10'. That is, the X axis direction is the length direction of the camera module 1', the Y axis direction is the width direction of the camera module 1', and the Z axis direction is the height direction of the camera module 1'. It should be understood that in the embodiment of the present application, the optical axis of the optical lens 10' is also used as the optical axis of the camera module 1'.

As shown in FIGS. 20A to 20B , the light deflecting element 30’ includes a plurality of reflective surfaces. The light emitted from the optical lens 10’ is reflected multiple times on the plurality of reflective surfaces of the light deflecting element 30’. The light is emitted from the light deflecting element 30’ and reaches the photosensitive component 40’. The photosensitive component 40’ and the optical lens 10’ are arranged on the same side of the light deflecting element 30’. Therefore, the height dimension of the camera module 1’ only needs to consider the sum of the height dimension of one of the photosensitive component 40’ and the optical lens 10’ and the height dimension of the light deflecting element 30’, without having to simultaneously superimpose the heights of the optical lens 10’, the light deflecting element 30’ and the photosensitive component 40’. In this way, the height dimension of the camera module 1’ can be reduced. In a specific example, the optical lens 10’ and the light deflection element 30’ form an “L” shaped structure, the photosensitive component 40’ is disposed in the corner space formed by the optical lens 10’ and the light deflection element 30’, the height dimension of the optical lens 10’ is greater than the height dimension of the photosensitive component 40’, and the top surface of the optical lens 10’ is higher than the top surface of the photosensitive component 40’, so that the photosensitive component 40’ does not affect the height of the camera module 1’, wherein the top surface of the optical lens 10’ and the top surface of the photosensitive component 40’ refer to the side thereof away from the light deflection element 30’ respectively. In the present application, the optical lens 10’ and the light deflection element 30’ together constitute the optical component of the camera module 1’ described in the present application, in other words, the optical component includes the optical lens 10’ and the light deflection element 30’.

The optical lens 10' includes a lens barrel 12' and at least one optical lens 11' accommodated in the lens barrel 12'. The optical lens 10' collects light from the subject and transmits it to the light deflection element 30'. The optical lens 10' has an optical axis, and the optical axis of the optical lens 10' is perpendicular to the light deflection element 30'. In a specific example, as shown in FIG. 20A and FIG. 20B , the optical lens 10' includes three optical lenses 11', namely, a first lens L1', a second lens L2' and a third lens L3', which are arranged along the incident direction of the light. The first lens L1', the second lens L2' and the third lens L3' are fixed to the lens barrel 12', so that the distance between the three optical lenses 11' is maintained by the lens barrel 12'.

In one embodiment of the present application, the camera module 1' further includes a compensation lens group 20', which can be disposed between the light deflection element 30' and the photosensitive component 40'. The compensation lens group 20' can further modulate the light emitted from the light deflection element 30'. For example, the compensation lens group 20' can further converge the light emitted from the light deflection element 30' to reduce the back focus, thereby reducing the camera module 1'. In a specific example, as shown in FIG20B , the compensation lens group 20 ′ includes a compensation lens 21 ′, and the compensation lens 21 ′ is disposed between the light deflection element 30 ′ and the photosensitive component 40 ′. For example, the compensation lens 21 ′ can be fixed to the light deflection element 30 ′ by gluing.

Continuing to refer to FIG. 17 to FIG. 23B , the photosensitive component 40′ includes a chip circuit board 42′, a photosensitive chip 41′ electrically connected to the chip circuit board 42′, and at least one electronic component, wherein the photosensitive surface of the photosensitive chip 41′ faces the light turning element 30′ to receive the light emitted from the light turning element 30′. In a specific example, the photosensitive chip 41′ is fixed to the side of the chip circuit board 42′ facing the light turning element 30′. The at least one electronic component can be implemented as a passive electronic device such as a capacitor or a resistor or an active electronic device such as a diode or a memory chip, and the at least one electronic component can be arranged on the side of the chip circuit board 42′ facing the light turning element 30′ or on the other side away from the light turning element 30′. It should be understood that the photosensitive component 40′ and the optical lens 10′ are arranged on the same side of the light turning element 30′, which means that the photosensitive chip 41′ and the optical lens 10′ in the photosensitive component 40′ are arranged on the same side of the light turning element 30′. Thus, in a specific example, the direction in which the light is incident on the optical lens 10' is opposite to the direction in which the light is incident on the photosensitive chip 41' of the photosensitive component 40'.

Furthermore, in some embodiments of the present application, the camera module 1' further includes a filter component 50', and the filter component 50' is disposed on the optical path of the light, so that the camera module 1' can filter out unnecessary stray light (such as infrared light) through the filter component 50'. In one embodiment of the present application, the filter component 50' is disposed between the light turning element 30' and the photosensitive component 40'. For example, in a specific example, the filter component 50' includes a filter element 51' and a filter element bracket 52' for supporting the filter element 51'. The filter element 51' is supported on the filter element bracket 52' by, for example, gluing. The two sides of the filter element bracket 52' are respectively fixed to the chip circuit board 42', so that the filter component 50' is disposed between the light turning element 30' and the photosensitive chip 41'. In other embodiments of the present application, the filter component 50’ can be arranged in the light deflection element 30’ and/or the optical lens 10’. For example, the filter component 50’ can be implemented as a layer of filter film, and the filter film is attached to a surface of the light deflection element 30’, or the filter film is attached to the surface of at least one optical lens 11’ of the optical lens 10’, so as to achieve the function of filtering out infrared light.

In the present application, as shown in FIG. 20A and FIG. 30B , the light deflection element 30 ′ has a plurality of reflective surfaces so that the light entering the light deflection element 30 ′ can be reflected multiple times, which can effectively increase the optical TTL, making the camera module 1 ′ suitable for capturing objects at a long distance and providing high-quality images of the objects at a long distance. TTL refers to the distance on the optical axis between the front vertex of the light incident side (facing the object) of the optical lens 10 ′ of the camera module 1 ′ and the image plane at the photosensitive component 40 ′.

Under normal circumstances, the increase of TTL will increase the size of the camera module, making it unsuitable for integration in small mobile devices. In one embodiment of the present application, the light deflection element 30' extends in the horizontal direction, that is, the length of the light deflection element 30' in the horizontal direction is greater than its height or thickness in the height direction. When the light is reflected multiple times in the light deflection element 30', the light deflection element 30' can maintain a lower height or thickness, thereby avoiding an increase in the height of the camera module. In other words, the length of the light deflection element 30' extending in the horizontal direction is greater than its height extending in the height direction, so as to reduce the height of the camera module while maintaining effectiveness, thereby meeting the demand for miniaturization of the camera module.

In one embodiment of the present application, the number of times the light is reflected in the light turning element 30' is an odd number, the photosensitive component 40' and the optical lens 10' are centrally arranged on the same side of the light turning element 30', and the light passing through the optical lens 10' is reflected in the light turning element 30' for an odd number of times before being emitted to reach the photosensitive component 40'. In another embodiment of the present application, the number of times the light is reflected in the light turning element 30' is an even number, the photosensitive component 40' and the optical lens 10' are respectively arranged on the opposite sides of the light turning element 30', and the light passing through the optical lens 10' is reflected in the light turning element 30' for an even number of times before being emitted to reach the photosensitive component 40'.

Specifically, in one embodiment of the present application, the light deflecting element 30' includes at least four surfaces, at least three of the at least four surfaces are reflective surfaces, and the light is reflected on at least three reflective surfaces in the light deflecting element 30'. For example, the light deflecting element 30' includes a trapezoidal prism, and the cross-section of the light deflecting element 30' is a trapezoid. When the light deflecting element 30' includes three reflective surfaces, the light is reflected three times in the light deflecting element 30'; when the light deflecting element 30' includes four reflective surfaces, the light is reflected five times or four times in the light deflecting element 30', which will be described in detail later in the present application. Of course, in other embodiments of the present application, the light deflecting element 30' may include prisms of other shapes, such as triangular prisms, pentagonal prisms, hexagonal prisms, etc., and still provide the above-mentioned light deflection function and design benefits, which is not limited by the present application.

As shown in FIG. 20A and FIG. 20B , in one embodiment of the present application, the light deflection element 30 ′ is implemented as a trapezoidal prism, and the light deflection element 30 ′ includes four surfaces, for example, a first surface 31 ′, a second surface 32 ′, a third surface 33 ′, and a fourth surface 34 ′. The plane where the first surface 31 ′ is located is parallel to the plane where the third surface 33 ′ is located, the length of the third surface 33 ′ is less than the length of the first surface 31 ′, and the plane where the second surface 32 ′ is located intersects with the plane where the fourth surface 34 ′ is located. Among them, at least three of the four surfaces of the light deflection element 30 ′ have a reflective function, for example, the first surface 31 ′, the second surface 32 ′, the third surface 33 ′, and the fourth surface 34 ′ are reflective surfaces, have a reflective function, and can reflect light, thereby realizing four, five, or more reflections of light in the light deflection element 30 ′; or, only the first surface 31 ′, the second surface 32 ′, and the fourth surface 34 ′ can be reflective surfaces, have a reflective function, and can reflect light, thereby realizing only three reflections of light in the light deflection element 30 ′.

In a specific example, the angle at which the second surface 32’ intersects with the first surface 31’ is an acute angle, the angle at which the fourth surface 34’ intersects with the first surface 31’ is an acute angle, the angle at which the second surface 32’ intersects with the third surface 33’ is an obtuse angle, and the angle at which the fourth surface 34’ intersects with the third surface 33’ is an obtuse angle. Among them, the angle at which the second surface 32’ intersects with the first surface 31’ may be in the range of 25° and 35°, and the angle at which the fourth surface 34’ intersects with the first surface 31’ may be in the range of 25° and 35°. It should be understood that the angles between the various surfaces of the light deflection element 30’ can control the reflection angle of light when it is reflected in the light deflection element 30’, so as to realize the function of the light deflection element 30’ to reflect light multiple times.

Furthermore, the light deflection element 30' is an isosceles trapezoidal prism, that is, the cross section of the light deflection element 30' in the height direction is an isosceles trapezoid (similar to an isosceles trapezoid). As shown in the cross-sectional view of the trapezoidal prism (see FIG. 20A and FIG. 20B ), the second surface 32' and the fourth surface 34' are equal in length, and the second surface 32' and the fourth surface 34' are axially symmetrical. Among them, the angle between the second surface 32' and the first surface 31' is equal to the angle between the fourth surface 34' and the first surface 31', and the angle between the second surface 32' and the third surface 33' is equal to the angle between the fourth surface 34' and the third surface 33'. In a specific example, the optical axis of the incident light is axially symmetrical in the optical path of the light deflection element 30'.

In one embodiment of the present application, the second surface 32’, the fourth surface 34’ and/or the third surface 33’ of the light deflection element 30’ may be provided with a reflective coating, or a reflector may be provided, so that light can be reflected on the second surface 32’, the fourth surface 34’ and/or the third surface 33’. For example, in a specific example of the present application, the reflective coating may include a mirror coating based on a thin metal layer, a film with a white inner surface, etc. Further, at least a portion of the first surface 31’ of the light deflection element 30’ is provided with a reflective coating, and at least a portion of the first surface 31’ is not provided with a reflective coating, so that the first surface 31’ can transmit light or allow light to pass through the first surface 31’. Further, the first surface 31’ may also reflect light under the phenomenon of total internal reflection.

It should be understood that when the incident angle of the light is close to or greater than a certain limiting angle (called the critical angle), total internal reflection may occur. The incident angle refers to the angle between the light incident on the surface and the line perpendicular to the surface at the incident point (called the normal line). Therefore, when the incident angle of the light is less than the critical angle, the first surface 31' of the light deflection element 30' allows the light to pass through; when the incident angle of the light is close to or greater than the critical angle, the first surface 31' of the light deflection element 30' may reflect the light at the corresponding surface.

Specifically, in one embodiment of the present application, the first surface 31' includes a light entrance area 311', a light exit area 312', and a reflection area 313' disposed between the light entrance area 311' and the light exit area 312', wherein the light entrance area 311' and the light exit area 312' are not provided with a reflection coating, so that light can enter the light turning element 30' from the light entrance area 311' and exit the light turning element 30' from the light exit area 312'. The reflection area 313' is provided with a reflection coating, so that light is reflected when passing through the reflection area 313'.

In one example, the size of the light entrance area 311' is equal to the size of the light exit area 312', and the size of the reflection area 313' is not less than the size of the light entrance area 311' or the light exit area 312', so that the light entering the light deflection element 30' from the light entrance area 311' can be reflected and then emitted from the light exit area 312' to reach the photosensitive component 40', thereby avoiding the loss of light and reducing the generation of stray light. In a specific example of the present application, the size of the light entrance area 311' is equal to the size of the reflection area 313' and is equal to the size of the light exit area 312', so that the multiple reflections of the light deflection element 30' are better, thereby avoiding the loss of light and reducing the generation of stray light.

Furthermore, the light entrance area 311' and the light exit area 312' are both arranged on the first surface 31', that is, the light entrance and exit of the camera module 1' are both located on the same side of the light deflection element 30'. In this way, the optical lens 10' and the photosensitive component 40' are concentrated on the same side of the light deflection element 30', so that the height of the camera module 1' is only determined by the sum of the height of the optical lens 10' or the photosensitive component 40' and the height of the light deflection element 30', which is conducive to reducing the height of the camera module 1'.

In one embodiment of the present application, the light deflecting element 30’ can reflect the light in the light deflecting element 30’ an odd number of times to guide the light from the optical lens 10’ to pass through the light deflecting element 30’ to reach the photosensitive component 40’. When the light is reflected three times in the light deflecting element 30’, the light passes through the light entrance area 311’ of the first surface 31’ to enter the light deflecting element 30’; at least some of the light passing through the light entrance area 311’ of the first surface 31’ is reflected at the second surface 32’; at least some of the light reflected from the second surface 32’ is reflected at the reflection area 313’ of the first surface 31’; at least some of the light reflected from the reflection area 313’ of the first surface 31’ is reflected at the fourth surface 34’; so that the light passes through the light exit area 312’ of the first surface 31’ to reach the photosensitive component 40’.

In another embodiment of the present application, as shown in FIG20A, when the light is reflected five times in the light turning element 30’, the light passes through the light entrance area 311’ of the first surface 31’ and enters the light turning element 30’; at least some of the light passing through the light entrance area 311’ of the first surface 31’ is reflected at the second surface 32’; at least some of the light reflected from the second surface 32’ is reflected at the reflection area 313’ of the first surface 31’; at least some of the light reflected from the reflection area 313’ of the first surface 31’ is reflected at the third surface 33’; at least some of the light reflected from the third surface 33’ is reflected at the light exit area 312’ of the first surface 31’; and, at least some of the light reflected from the light exit area 312’ of the first surface 31’ is reflected at the fourth surface 34’, so that the light passes through the light exit area 312’ of the first surface 31’ and reaches the photosensitive component 40’.

It should be understood that the light from the optical lens 10' can enter the light deflection element 30' through the light entrance area 311' of the first surface 31' and undergo an odd number of reflections in the light deflection element 30'. At least some of the light can reach the second surface 32' and then be reflected at the second surface 32', and at least some of the light reflected from the second surface 32' can reach the reflection area 313' or the light entrance area 311' of the first surface 31'. When light reaches the reflection area 313’ of the first surface 31’, it is reflected at the reflection area 313’ of the first surface 31’, and at least some of the light reflected from the reflection area 313’ of the first surface 31’ can reach the third surface 33’ or the fourth surface 34’, and be reflected at the third surface 33’ or the fourth surface 34’; when light reaches the light entrance area 311’ of the first surface 31’, when the incident angle of the light is close to or greater than the critical angle of the light turning element 30’, the light can be reflected at the light entrance area 311’ of the first surface 31’ under total internal reflection, and at least some of the light reflected from the light entrance area 311’ of the first surface 31’ can reach the third surface 33’ or the fourth surface 34’, and be reflected at the third surface 33’ or the fourth surface 34’.

If at least some of the light reflected from the first surface 31' reaches the fourth surface 34', and is finally reflected at the fourth surface 34', it leaves the light deflection element 30' to reach the photosensitive component 40'. In one embodiment, the light is reflected three times in the light deflection element 30', which can effectively increase the focal length between the optical lens 10' and the photosensitive component 40', that is, the optical TTL of the camera module 1' can be effectively increased, so that the camera module 1' is suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

If at least some of the light reflected from the first surface 31' reaches the third surface 33', then at least some of the light reflected from the third surface 33' can reach the light exit area 312' of the first surface 31'. When the incident angle of the light is close to or greater than the critical angle of the light deflection element 30', the light can be reflected at the light exit area 312' of the first surface 31' under total internal reflection. At least some of the light reflected from the light exit area 312' of the first surface 31' can reach the fourth surface 34', and finally reflected at the fourth surface 34', leaving the light deflection element 30' to reach the photosensitive component 40'. As shown in FIG20A, in this embodiment, the light is reflected five times in the light deflection element 30', which can effectively increase the focal length between the optical lens 10' and the photosensitive component 40', that is, the optical TTL of the camera module 1' can be effectively increased, so that the camera module 1' is suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

In another embodiment of the present application, the light deflection element 30' is implemented as a parallelogram prism, and the light deflection element 30' includes four surfaces, for example: a first surface 31', a second surface 32', a third surface 33' and a fourth surface 34'. The plane where the first surface 31' is located is parallel to the plane where the third surface 33' is located, and the plane where the second surface 32' is located is parallel to the plane where the fourth surface 34' is located. Among them, the four surfaces of the light deflection element 30' have a reflective function, for example: the first surface 31', the second surface 32', the third surface 33' and the fourth surface 34' are reflective surfaces that can reflect light.

In this embodiment, the light is reflected four times in the light deflection element 30', the photosensitive component 40' and the optical lens 10' are respectively arranged on the opposite sides of the light deflection element 30', and the light passing through the optical lens 10' is reflected four times in the light deflection element 30' before being emitted to the photosensitive component 40'. For example, the optical lens 10' is arranged on one side of the first surface 31', and the photosensitive component 40' is arranged on one side of the third surface 33'.

In one embodiment of the present application, the light deflection element 30' can be implemented as an integrated prism, as shown in FIG. 20A and FIG. 20B, and the integrated prism is a trapezoidal prism. In another embodiment of the present application, the light deflection element 30' can also be implemented as a split prism, that is, the The light deflection element 30' can be formed by combining a plurality of prisms. For example, the split prism includes at least two prisms: a first prism and a second prism, wherein, in a specific example of the present application, the first prism is a parallelogram prism, and the second prism is a triangular prism, and the first prism and the second prism are joined together by means of an optically transparent adhesive or a snap-fit, etc. to form the light deflection element 30'. In this way, when the light deflection element 30' is manufactured by means of a panelization method, the manufacturing process can be simplified and the utilization rate of the raw materials can be improved. Of course, it should be understood that in another specific example of the present application, the first prism can be a right-angled trapezoidal prism, and the second prism can be a right-angled triangular prism or a right-angled trapezoidal prism, and the first prism and the second prism are joined together by means of an optically transparent adhesive or a snap-fit, etc. to form the light deflection element 30'.

In another specific example of the present application, as shown in FIG21A, the split prism 36' also includes a third prism 363', wherein the first prism 361' is a right-angled trapezoidal prism, the second prism 362' is a rectangular prism, and the third prism 363' is a right-angled trapezoidal prism. The first prism 361', the second prism 362' and the third prism 363' are joined together by optically transparent adhesives or snaps to form a light deflection element 30'. In this way, when the light deflection element 30' is manufactured by means of a panel assembly method, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Alternatively, as shown in FIG21B , the first prism 361’ and the third prism 363’ are triangular prisms, and the second prism 362’ is a quadrilateral prism. For example, the first prism 361’ and the third prism 363’ are right-angled triangular prisms, and the second prism 362’ is a rectangular prism. Alternatively, the first prism 361’ and the third prism 363’ are triangular prisms, and the second prism 362’ is a parallelogram prism. The first prism 361’, the second prism 362’ and the third prism 363’ are joined together by optically transparent adhesives or snaps to form a light turning element 30’.

Continuing with reference to FIG. 21A , in the split prism 36’, the second prism 362’ is disposed between the first prism 361’ and the third prism 363’. When light passes through the light entrance area 311’ of the first prism 361’ and enters the first prism 361’, at least some of the light is reflected at least once in the first prism 361’ and reaches the second prism 362’. Then, at least some of the light reaching the second prism 362’ is reflected at least once in the second prism 362’ and reaches the third prism 363’. Finally, at least some of the light reaching the third prism 363’ is reflected at least once in the third prism 363’ and reaches the light exit area 312’ of the third prism 363’, and is emitted from the third prism 363’ to reach the photosensitive component 40’.

It should be understood that in the present application, the light entrance area 311' of the first prism 361' and the light exit area 312' of the third prism 363' are both arranged on the same side of the light deflection element 30' (split prism 36') so that light can enter and exit from the same side of the light deflection element 30'. In this way, the optical lens 10' and the photosensitive component 40' can be concentrated on the same side of the light deflection element 30' to reduce the height of the camera module 1'.

Furthermore, the light deflection element 30' may also include a shading film disposed between the first prism 361' and the second prism 362' and/or disposed between the second prism 362' and the third prism 363'. Specifically, as shown in FIG. 21A and FIG. 21B , a U-shaped shading film is disposed on the side of the second prism 362' facing the first prism 361', and a U-shaped shading film is disposed on the side of the second prism 362' facing the third prism 363'. It is understandable that the shading film may also be disposed on the side of the first prism 361' or the third prism 363' facing the second prism 362'. By providing the shading film, the influence of stray light on imaging can be reduced, and the problem of glare can be reduced.

It should be understood that the split prism 36' may also include other numbers of prisms, such as four prisms, five prisms, and six prisms, and the present application does not limit this. Of course, in other embodiments of the present application, the light deflection element 30' may also be implemented as a plurality of reflectors, and the plurality of reflectors are arranged at positions where light needs to be reflected to form the light deflection element 30'.

As shown in Figures 17, 18A, 18B, 19A, 19B, 22, 23A and 23B, in one example, the driving device 60' is implemented as a chip driving component for driving the photosensitive component 40' to move. Among them, Figure 17 shows a three-dimensional schematic diagram of the camera module 1'; Figure 18A shows a cross-sectional view of the camera module 1' along the length direction (i.e., the X-axis direction defined above); Figure 18B further shows an enlarged schematic diagram of the circular area in Figure 18A; Figure 19A shows a cross-sectional view of the camera module 1' along the width direction (i.e., the Y-axis direction defined above); Figure 19B further shows an enlarged schematic diagram of the circular area in Figure 3A; Figure 22 shows an exploded schematic diagram of the driving device 60', from which the implementation method of the focusing function of the camera module 1' can be known; Figures 23A and 23B show exploded schematic diagrams of the partial structure of the driving device 60' in two perspectives, namely, looking down and looking up, from which the implementation method of the anti-shake function can be known. The camera module 1' comprises a driving device 60' and an optical lens 10', a light deflection element 30', a filter assembly 50' and a photosensitive assembly 40' arranged in the driving device 60', wherein the photosensitive assembly 40' is arranged on the light-emitting side of the light deflection element 30', and the optical lens 10' is arranged on the light-incident side of the light deflection element 30'. The light emitted by the optical lens 10' is reflected multiple times on multiple reflection surfaces of the light deflection element 30' and then emitted by the light deflection element 30' and reaches the photosensitive assembly 40'. The light deflection element 30' is fixed to the fixed part of the driving device 60', and the photosensitive assembly 40' is fixed to the movable part of the driving device 60'. The optical lens 10' is directly or indirectly fixed to the light deflection element 30', the filter component 50' is directly or indirectly fixed to the photosensitive component 40', and the driving device 60' can drive the photosensitive component 40' to move relative to the light deflection element 30', thereby changing the optical performance of the camera module 1' by moving the chip.

Continuing to refer to FIGS. 17 , 18A, 18B, 19A, 19B, 22 , 23A and 23B, the driving device 60’ includes a frame 64’, a movable carrier 67’ and an anti-shake driving unit 66’. The anti-shake driving unit 66’ connects the frame 64’ and the movable carrier 67’ and drives the movable carrier 67’ to move in a horizontal direction relative to the frame 64’. Specifically, the movable carrier 67’ is movably disposed in the frame 64’, and the anti-shake driving unit 66’ is disposed between the frame 64’ and the movable carrier 67’, so that the movable carrier 67’ is driven by the anti-shake driving unit 66’ to move in a horizontal direction relative to the frame 64’. The driving device 60’ is configured to drive the photosensitive component 40’ to move. The photosensitive component 40’ is movably arranged at one end of the driving device 60’ away from the optical lens 10’. Specifically, the driving device 60’ is configured to drive the photosensitive chip 41’ of the photosensitive component 40’ to move.

It should be understood that the anti-shake drive unit 66’ is disposed between the frame 64’ and the movable carrier 67’, which includes not only the case where the anti-shake drive unit 66’ is disposed between the side of the frame 64’ facing the movable carrier 67’ and the side of the movable carrier 67’ facing the frame 64’, but also the case where the anti-shake drive unit 66’ is disposed between the outer side of the frame 64’ away from the movable carrier 67’ and the outer side of the movable carrier 67’ away from the frame 64’. In other words, in the present application, at least a portion of the anti-shake drive unit 66’ is located between the frame 64’ and the movable carrier 67’, which means that the anti-shake drive unit 66’ is disposed between the frame 64’ and the movable carrier 67’, so that the frame 64’ or the movable carrier 67’ can be provided with a groove or a through hole to accommodate a portion of the anti-shake drive unit 66’.

Specifically, as shown in FIG. 18A , FIG. 18B , FIG. 19A and FIG. 19B , the photosensitive component 40’ is fixed to the movable carrier 67’ in a direction facing the light turning element 30’, so that the photosensitive component 40’ moves with the movable carrier 67’ to realize the chip anti-shake function. In other words, in a specific example, the photosensitive component 40’ is fixed above the movable carrier 67’. It should be understood that in the present application, the direction in which the photosensitive component 40’ faces the light turning element 30’ refers to the direction in which the photosensitive chip 41’ of the photosensitive component 40’ faces the light turning element 30’, and the photosensitive chip 41’ of the photosensitive component 40’ faces the light turning element 30’ to receive the light emitted by the light turning element 30’. In other words, compared with the conventional upright module, the photosensitive component 40’ is fixed to the movable carrier 67’ in an inverted state. The side of the chip circuit board 42' of the photosensitive component 40' facing the light deflection element 30' is the front side of the chip circuit board 42'. In a specific example, the movable carrier 67' is fixed to the front side of the chip circuit board 42', and the chip circuit board 42' is fixed above the movable carrier 67'. It is worth mentioning that the movable carrier 67' can be directly fixed to the chip circuit board 42' by gluing; the movable carrier 67' can also be indirectly fixed to the chip circuit board 42' by being fixed to the filter element bracket 52' of the filter component 50'.

There is an air gap between the movable carrier 67’ and the light deflection element 30’, and between the movable carrier 67’ and the frame 64’, respectively, so that the anti-shake driving unit 66’ can drive the movable carrier 67’ to move in the horizontal direction (i.e., the direction perpendicular to the optical axis of the optical lens 10’) relative to the frame 64’ and the light deflection element 30’, thereby realizing the chip anti-shake function. It should be understood that in the present application, the horizontal part of the air gap formed between the movable carrier 67’ and the light deflection element 30’, and between the movable carrier 67’ and the frame 64’ is suitable for being adjusted in the realization of the chip anti-shake function. In a specific example, the movable carrier 67’ is in the shape of a “Π” and is arranged around the light deflection element 30’.

The frame 64’ is arranged on the outside of the movable carrier 67’, and the anti-shake driving unit 66’ is arranged between the movable carrier 67’ and the frame 64’. The anti-shake driving unit 66’ includes at least one anti-shake magnet 661’ and at least one anti-shake coil 662’. The at least one anti-shake magnet 661’ is directly or indirectly fixed to one of the movable carrier 67’ and the frame 64’, and the at least one anti-shake coil 662’ is directly or indirectly fixed to the other of the movable carrier 67’ and the frame 64’. The at least one anti-shake magnet 661’ and the at least one anti-shake coil 662’ are arranged opposite to each other, so that the movable carrier 67’ can be driven to move relative to the frame 64’ by the magnetic force between the at least one anti-shake magnet 661’ and the at least one anti-shake coil 662’ to realize the chip anti-shake function.

In a specific example, at least one anti-shake magnet 661' is disposed on the frame 64', at least one anti-shake coil 662' is disposed on the movable carrier 67', at least one anti-shake magnet 661' includes a first anti-shake magnet 6611' and a second anti-shake magnet 6612', and at least one anti-shake coil 662' includes a first anti-shake coil 6621' and a second anti-shake coil 6622'. In other words, the anti-shake drive unit 66' includes a first anti-shake magnet 6611' and a second anti-shake magnet 6612' fixed to the frame 64', and a first anti-shake coil 6621' and a second anti-shake coil 6622' fixed to the movable carrier 67'. Among them, the first anti-shake magnet 6611' and the second anti-shake magnet 6612' are disposed on two adjacent sides of the top surface of the frame 64', and the first anti-shake coil 6621' and the second anti-shake coil 6622' are disposed on two adjacent sides of the movable carrier 67'. The first anti-shake coil 6621' and the first anti-shake magnet 6611' are arranged opposite to each other so that the first anti-shake coil 6621' interacts with the first anti-shake magnet 6611' after being energized to generate a magnetic field, thereby driving the movable carrier 67' The second anti-shake coil 6622' and the second anti-shake magnet 6612' are arranged relative to each other so that the second anti-shake coil 6622' interacts with the second anti-shake magnet 6612' after being energized to generate a magnetic field, thereby driving the movable carrier 67' to move relative to the frame 64' along the second horizontal direction. That is, in this example, in the process of realizing chip anti-shake, at least one anti-shake coil 662' (the first anti-shake coil 6621' and the second anti-shake coil 6622') serves as a mover, and at least one anti-shake magnet 661' (the first anti-shake magnet 6611' and the second anti-shake magnet 6612') serves as a stator.

In one example, the first anti-shake magnet 6611’ and the second anti-shake magnet 6612’ are arranged on two adjacent sides perpendicular to each other on the top surface of the frame 64’, the first anti-shake coil 6621’ and the second anti-shake coil 6622’ are arranged on two adjacent sides perpendicular to each other on the movable carrier 67’, and the first horizontal direction is perpendicular to the second horizontal direction. For example, the first horizontal direction can be the Y-axis direction, and the second horizontal direction can be the X-axis direction.

In other words, the first anti-shake coil 6621' and the first anti-shake magnet 6611' are arranged relative to each other in the height direction, and the second anti-shake coil 6622' and the second anti-shake magnet 6612' are arranged relative to each other in the height direction, that is, in this specific example, the anti-shake drive unit 66' includes at least one anti-shake magnet 661' and at least one anti-shake coil 662' arranged relative to each other in the height direction, and the height direction is parallel to the direction of the optical axis of the optical lens 10'. In this way, the relative area between the first anti-shake magnet 6611' and the first anti-shake coil 6621' can be made larger at a smaller height size, and the relative area between the second anti-shake magnet 6612' and the second anti-shake coil 6622' can be made larger, thereby providing a larger driving force in the horizontal direction. In particular, at least one anti-shake coil 662’ is disposed above at least one anti-shake magnet 661’, so that at least one anti-shake coil 662’ is disposed on the movable carrier 67’, and the photosensitive component 40’ is also fixed to the movable carrier 67’, so that at least one anti-shake coil 662’ is electrically connected to the photosensitive component 40’. In a specific example, the first anti-shake coil 6621’ and the second anti-shake coil 6622’ are respectively fixed to the two sides of the chip circuit board 42’ and are respectively electrically connected to the chip circuit board 42’, and the positions corresponding to the first anti-shake coil 6621’ and the second anti-shake coil 6622’ on the movable carrier 67’ are respectively formed with an opening to accommodate the first anti-shake coil 6621’ and the second anti-shake coil 6622’, so that the first anti-shake coil 6621’ and the first anti-shake magnet 6611’ are directly disposed face to face, and so that the second anti-shake coil 6622’ and the second anti-shake magnet 6612’ are directly disposed face to face. In this specific example, at least one anti-shake coil 662’ (a first anti-shake coil 6621’ and a second anti-shake coil 6622’) is indirectly fixed to the movable carrier 67’ by being fixed to a chip circuit board 42’ fixed to the movable carrier 67’. In this way, at least one anti-shake magnet 661’ drives at least one anti-shake coil 662’ and the chip circuit board 42’ directly or indirectly fixed to the anti-shake coil 662’ and the movable carrier 67’ to move in a horizontal direction.

It is worth mentioning that the movable carrier 67’ can be driven to move horizontally relative to the frame 64’ by the magnetic force between the first anti-shake coil 6621’ and the first anti-shake magnet 6611’ and the magnetic force between the second anti-shake coil 6622’ and the second anti-shake magnet 6612’ at the same time, or the movable carrier 67’ can be driven to move horizontally relative to the frame 64’ only by the magnetic force between the first anti-shake coil 6621’ and the first anti-shake magnet 6611’ or the magnetic force between the second anti-shake coil 6622’ and the second anti-shake magnet 6612’.

Specifically, the frame 64’ has an opening facing the side of the light turning element 30’, and the frame 64’ includes an integrally formed first frame portion 643’, a second frame portion 644’ and a frame connecting portion 645’, wherein the first frame portion 643’ and the second frame portion 644’ are respectively connected to the two ends of the frame connecting portion 645’ and are respectively perpendicular to the frame connecting portion 645’, so that the frame 64’ is in a “Π” shape to avoid the position of the light turning element 30’ and reduce the size of the driving device 60’, and the frame 64’ is arranged around three sides of the light turning element 30’. The first anti-shake magnet 6611' is installed on the top surface of the first frame part 643', and the top surface of the first frame part 643' has a groove to accommodate the first anti-shake magnet 6611'. The second anti-shake magnet 6612' is installed on the top surface of the frame connecting part 645', and the top surface of the frame connecting part 645' also has a groove to accommodate the second anti-shake magnet 6612'. In this way, the size of the driving device 60' and the camera module 1' can be reduced. In other words, the first anti-shake magnet 6611' and the second anti-shake magnet 6612' are installed on two adjacent sides of the top surface of the frame 64'. It should be understood that the "Π" shape of the frame 64' can be obtained when looking down at the frame 64' from the height direction.

Correspondingly, the movable carrier 67' has an opening facing one side of the light deflection element 30'. The movable carrier 67' includes an integrally formed first carrier portion 671', a second carrier portion 672' and a carrier connecting portion 673', wherein the first carrier portion 671' and the second carrier portion 672' are respectively connected to the two ends of the carrier connecting portion 673' and are respectively perpendicular to the carrier connecting portion 673', so that the movable carrier 67' is in a "Π" shape to avoid the position of the light deflection element 30' and reduce the size of the driving device 60'. The movable carrier 67' is arranged around three sides of the light deflection element 30'. An opening is formed at a position corresponding to the first anti-shake coil 6621' on the first carrier portion 671' to accommodate the first anti-shake coil 6621', and an opening is also formed at a position corresponding to the second anti-shake coil 6622' on the carrier connecting portion 673' to accommodate the second anti-shake coil. In other words, the first anti-shake coil 6621' and the second anti-shake coil 6622' are arranged on two adjacent sides of the movable carrier 67'. It should be understood that the movable carrier 67' is in the shape of "Π" and can also be viewed from the height direction. The carrier 67' is obtained.

It is worth mentioning that, as shown in Figures 18A, 18B and 19A, the anti-shake drive unit 66’ extends downward from the chip circuit board 42’ in the height direction, the bottom surface of the anti-shake drive unit 66’ is lower than the top surface of the light turning element 30’ but higher than the bottom surface of the light turning element 30’, and the anti-shake drive unit 66’ is arranged on the side of the light turning element 30’, so that the height of the driving device 60’ and the camera module 1’ is not increased due to the setting of the anti-shake drive unit 66’. Specifically, the first anti-shake coil 6621’ and the first anti-shake magnet 6611’ extend downward from the chip circuit board 42’ along the height direction, and the bottom surface of the first anti-shake magnet 6611’ is lower than the top surface of the light turning element 30’ but higher than the bottom surface of the light turning element 30’. The second anti-shake coil 6622’ and the second anti-shake magnet 6612’ extend downward from the chip circuit board 42’ along the height direction, and the bottom surface of the second anti-shake magnet 6612’ is lower than the top surface of the light turning element 30’ but higher than the bottom surface of the light turning element 30’. The first anti-shake magnet 6611’ and the second anti-shake magnet 6612’ are arranged on the side of the light turning element 30’.

In this embodiment, the driving device 60' further includes an anti-shake support portion 68' and an anti-shake magnetic attraction member 69'. As shown in FIG. 23A and FIG. 23B , the anti-shake support portion 68' is disposed between the frame 64' and the movable carrier 67' so as to maintain an air gap between the frame 64' and the movable carrier 67', thereby reducing the resistance encountered by the movable carrier 67' when moving relative to the frame 64'. In a specific example, the anti-shake support portion 68' can be implemented as a ball 681', and the anti-shake support portion 68' includes at least three balls 681', and the at least three balls 681' are disposed between the movable carrier 67' and the frame 64' along the height direction and support the movable carrier 67' and the frame 64', so as to maintain a fixed air gap between the movable carrier 67' and the frame 64' in the height direction. It should be understood that the ball 681' can roll between the movable carrier 67' and the frame 64', and the ball 681' can also interact between the movable carrier 67' and the frame 64'. For example, the ball 681' can be fixed to the movable carrier 67' or the frame 64' by insert molding or bonding. It should be understood that the anti-shake support part 68' can also be implemented as other elements such as a spring or a slider.

The anti-shake magnetic component 69’ is made of a material suitable for being attracted by a magnet. The anti-shake magnetic component 69’ is directly or indirectly fixed to the movable carrier 67’ and corresponds to at least one anti-shake magnet 661’. The anti-shake magnetic component 69’ is arranged above at least one anti-shake magnet 661’, so that the movable carrier 67’ is adsorbed toward the frame 64’ through the magnetic force between the anti-shake magnetic component 69’ and at least one anti-shake magnet 661’, so that at least three balls 681’ are clamped between the movable carrier 67’ and the frame 64’, so that the movable carrier 67’ and the frame 64’ clamp at least three balls 681’ in the height direction. 18A, 18B and 19A, the number of anti-shake magnetic suction components 69' is 2, and the anti-shake magnetic suction components 69' are indirectly fixed to the movable carrier 67' by being fixed to the circuit board. Specifically, the two anti-shake magnetic suction components 69' are respectively arranged between the first anti-shake coil 6621' and the second anti-shake coil 6622', so that the two anti-shake magnetic suction components 69' can correspond to the first anti-shake magnet 6611' and the second anti-shake magnet 6612' in the height direction. In other words, the two anti-shake magnetic suction components 69' overlap with the first anti-shake magnet 6611' and the second anti-shake magnet 6612' in the height direction. It should be understood that the anti-shake magnetic suction component 69' can also be directly fixed to the movable carrier 67' by insert molding or bonding, so that the magnetic attraction between at least one anti-shake magnet 661' and the anti-shake magnetic suction component 69' can adsorb the movable carrier 67' to the frame 64'. In other words, the two anti-shake magnetic parts 69’ are fixed to the movable carrier 67’ and are magnetically attracted to the first anti-shake magnet 6611’ and the second anti-shake magnet 6612’ respectively so that the movable carrier 67’ is adsorbed to the frame 64’ and clamps the anti-shake support part 68’.

Further, continuing to refer to Figures 23A and 23B, in order to limit the range of movement of the ball 681', the frame 64' also includes at least three first ball grooves 647' formed on the top surface of the frame 64', and the movable carrier 67' also includes at least three second ball grooves 674' formed on the bottom surface of the movable carrier 67', wherein the top surface of the frame 64' refers to the side thereof facing the movable carrier 67', and the bottom surface of the movable carrier 67' refers to the side thereof facing the frame 64', and the positions of the at least three first ball grooves 647' and the at least three second ball grooves 674' correspond to each other. In one example, the anti-shake support portion 68' includes four balls 681', four first ball grooves 647' are formed at four corners of the top surface of the frame 64', four second ball grooves 674' are formed at four corners of the bottom surface of the movable carrier 67', and the anti-shake magnetic suction member 69' fixed to the movable carrier 67' is magnetically attracted to at least one anti-shake magnet 661', so that the four balls 681' are respectively clamped between the four corners of the frame 64' and the four corners of the movable carrier 67'. Specifically, two first ball grooves 647' are formed on the top surface of the first frame portion 643', and the other two first ball grooves 647' are formed on the top surface of the second frame portion 644'; two second ball grooves 674' are formed on the bottom surface of the first carrier portion 671', and the other two second ball grooves 674' are formed on the bottom surface of the second carrier portion 672'.

It is worth mentioning that the driving device 60' further includes a frame cover 640' fixed to the frame 64', and the frame cover 640' is arranged above the frame 64' in the height direction so that the movable carrier 67' is confined in the accommodating cavity formed by the frame cover 640' and the frame 64'. It should be understood that during the falling process, the magnetic attraction force between the anti-shake magnetic attraction member 69' and the anti-shake magnet 661' is difficult to keep the movable carrier 67' and the frame 64' Due to the positional relationship between them, when the movable carrier 67' produces a large displacement relative to the frame 64', the ball 681' will be separated from the first ball groove 647' and the second ball groove 674'. Therefore, in the present application, a frame cover 640' is further provided to limit the moving stroke of the movable carrier 67' in the height direction through the frame cover 640', thereby avoiding the situation where the ball 681' falls off.

Furthermore, the driving device 60’ can also realize the chip focusing function. Specifically, as shown in FIG. 19A , FIG. 19B and FIG. 22 , the driving device 60’ also includes a fixed base 61’ and a focusing driving unit 62’. The focusing driving unit 62’ connects the fixed base 61’ and the frame 64’ to drive the frame 64’ to move in the height direction relative to the fixed base 61’. Specifically, the frame 64’ is movably disposed in the fixed base 61’, and the focusing driving unit 62’ is disposed between the fixed base 61’ and the frame 64’, so that the frame 64’ is driven by the focusing driving unit 62’ to move in the height direction relative to the fixed base 61’. As the frame 64’ is moved, the movable carrier 67’, the anti-shake driving unit 66’, the anti-shake supporting unit 68’ and the anti-shake magnetic component 69’ arranged in the frame 64’ also move with the movement of the frame 64’, and then the photosensitive component 40’ fixed to the movable carrier 67’ also moves with the movement of the frame 64’, thereby realizing the chip focusing function.

It should be understood that the focus drive unit 62’ is disposed between the frame 64’ and the fixed base 61’, which includes not only the case where the focus drive unit 62’ is disposed between the side of the frame 64’ facing the fixed base 61’ and the side of the fixed base 61’ facing the frame 64’, but also the case where the focus drive unit 62’ is disposed between the outer side of the frame 64’ away from the fixed base 61’ and the outer side of the fixed base 61’ away from the frame 64’. In other words, in the present application, at least a portion of the focus drive unit 62’ is located between the frame 64’ and the fixed base 61’, which means that the focus drive unit 62’ is disposed between the frame 64’ and the fixed base 61’, so that the frame 64’ or the fixed base 61’ may be provided with a groove or a through hole to accommodate a portion of the focus drive unit 62’.

The driving device 60' further includes an upper cover 610' fixed to the fixed base 61', the upper cover 610' and the fixed base 61' form a receiving chamber to accommodate the focus driving unit 62', the frame 64', the frame cover 640', the anti-shake driving unit 66' and the movable carrier 67', and the upper cover 610' has a lens opening 6101', so that the optical lens 10' can extend from the driving device 60' through the lens opening 6101'. There is an air gap between the frame 64' and the fixed base 61', so that the focus driving unit 62' can drive the frame 64' to move relative to the fixed base 61' in the height direction, thereby realizing the chip focusing function. It should be understood that in the present application, the part of the air gap formed between the frame 64' and the fixed base 61' in the height direction is suitable for being adjusted in the realization of the chip focusing function.

22 , the fixed base 61′ includes a base body 611′ and four base side walls 612′ extending upward from four sides of the base body 611′, and the upper cover 610′ is sleeved on the outer sides of the four base side walls 612′. Among them, one of the four base side walls 612′ parallel to the length direction of the driving device 60′ (i.e., the length direction of the light turning element 30′) serves as a focus fixing portion 613′ for setting the focus driving portion 62′. In other words, the fixed base 61′ includes a base body 611′ and a focus fixing portion 613′ extending upward from one side of the base body 611′, and the focus fixing portion 613′ is fixed to one side of the base body 611′. Specifically, the focus fixing portion 613′ is fixed to the long side of the base body 611′, and the focus fixing portion 613′ is parallel to the length direction of the driving device 60′. It should be understood that the focus fixing portion 613' can be fixed to the base body 611' by bonding or integral molding.

It is worth mentioning that, as shown in Fig. 17 to Fig. 19A, the driving device 60' may further include a bearing portion 37', the bearing portion 37' having a bearing cavity for mounting the light deflection element 30'. In other words, the light deflection element 30' is mounted on the bearing portion 37', and the shape of the bearing cavity of the bearing portion 37' is adapted to the shape of the light deflection element 30'. That is, in one embodiment of the present application, the light deflection element 30' is fixed by being mounted on the bearing portion 37'. For example, when the light deflection element 30' is implemented as a trapezoidal prism, the bearing cavity of the bearing portion 37' has a size that gradually decreases from the top to the bottom. In a specific example of the present application, the bearing portion 37’ is fixed to the middle part of the fixed base 61’ by bonding. Specifically, the base body 611’ has an opening arranged toward the light deflection element 30’, and the bearing portion 37’ is arranged in the opening of the fixed base 61’ and fixed to the opening of the fixed base 61’; in another specific example of the present application, the bearing portion 37’ may also be integrally formed in the middle part of the fixed base 61’, for example, the bearing portion 37’ and the fixed base 61’ may be directly integrally formed by injection molding.

Continuing to refer to FIGS. 19A, 19B and 22, the focus driving unit 62' is disposed between the frame 64' and the focus fixing unit 613' of the fixed base 61', and the focus driving unit 62' includes a pair of focus magnets 621' and a pair of focus coils 622', wherein the focus magnet 621' is fixed to one of the frame 64' and the focus fixing unit 613', and the focus coil 622' is fixed to the other of the frame 64' and the focus fixing unit 613', and the focus magnet 621' and the focus coil 622' are disposed opposite to each other, so that the frame 64' can be driven by the magnetic force between the focus magnet 621' and the focus coil 622'. It moves in the height direction relative to the fixed base 61' to achieve the chip focusing function.

In a specific example, the focus magnet 621’ is fixed on the side of the frame 64’, the focus coil 622’ is fixed on the focus fixing portion 613’ of the fixed base 61’, and the focus coil 622’ is arranged opposite to the focus magnet 621’. In other words, the focus coil 622’ and the focus magnet 621’ are arranged in the horizontal direction between the frame 64’ and the focus fixing portion 613’ of the fixed base 61’, and the focus drive unit 62’ includes the focus coil 622’ and the focus magnet 621’ arranged opposite to each other in the horizontal direction, and the horizontal direction refers to the direction perpendicular to the optical axis of the optical lens 10’. In this way, a larger driving force in the height direction can be provided with a smaller lateral dimension (dimensions in the length direction and the width direction).

It should be understood that, in the process of implementing chip focusing, the focusing coil 622' fixed to the focusing fixing part 613' drives the focusing magnet 621' to move in the height direction relative to the focusing coil 622', so that the frame 64' fixed to the focusing magnet 621' moves in the height direction along with the movement of the focusing magnet 621'. That is, in this example, in the process of implementing chip focusing, the focusing magnet 621' serves as a mover and the focusing coil 622' serves as a stator.

Furthermore, the focus driving part 62’ further includes a focus circuit board 623’, and the focus coil 622’ is fixed and electrically connected to the focus circuit board 623’. The focus circuit board 623’ is fixed to the focus fixing part 613’, so that the focus coil 622’ is indirectly fixed to the focus fixing part 613’ through the focus circuit board 623’. In a specific example, the focus circuit board 623’ is attached to the outer side surface of the focus fixing part 613’, and a through hole is provided on the focus fixing part 613’ to expose the focus coil 622’ and to face the focus magnet 621’. The through hole on the focus fixing part 613’ accommodates the focus coil 622’, so that the lateral size of the driving device 60’ can be reduced. It should be understood that the outer side surface of the focus fixing part 613’ refers to the side of the focus fixing part 613’ away from the frame 64’. It is worth mentioning that the focusing circuit board 623’ is further electrically connected to the chip circuit board 42’. The focusing circuit board 623’ may be a flexible circuit board or a hard-soft combination board. In this way, the focusing circuit board 623’ may be arranged in the driving device 60’ in a bent state so that the focusing circuit board 623’ may be extended to a position convenient for electrical connection with the chip circuit board 42’.

Correspondingly, the focus magnet 621’ is installed on the outer side surface of the frame 64’ so that a small distance can be maintained between the focus magnet 621’ and the focus coil 622’, thereby enhancing the magnetic force between the focus magnet 621’ and the focus coil 622’. Specifically, the focus magnet 621’ is installed on the outer side surface of the second frame portion 644’, and the outer side surface of the second frame portion 644’ has a groove to accommodate the focus magnet 621’, so that the size of the drive device 60’ and the camera module 1’ can be reduced. It should be understood that the outer side surface of the frame 64’ refers to the side of the frame 64’ facing the fixed base 61’ or the upper cover 610’, and the outer side surface of the second frame portion 644’ refers to the side of the second frame portion 644’ facing the focus fixing portion 613’.

It is worth mentioning that in the present application, as shown in FIG19A , since the focus magnet 621’ is arranged on the side of the focus fixing portion 613’ of the fixed base 61’, the bottom surface of the focus magnet 621’ can be lower than the top surface of the light turning element 30’. In other words, the focus magnet 621’ extends downward, so that the relative area between the focus magnet 621’ and the focus coil 622’ can be increased, thereby enhancing the driving force of the focus drive portion 62’. Furthermore, in the present application, the focus magnet 621’, the first anti-shake magnet 6611’ and the second anti-shake magnet 6612’ are all arranged on the peripheral side of the light turning element 30’, so that the height dimensions of the drive device 60’ and the camera module 1’ can be designed to be smaller.

It is worth mentioning that in the present application, the first frame portion 643’ and the frame connecting portion 645’ are used to install the first anti-shake magnet 6611’ and the second anti-shake magnet 6612’ respectively, the second frame portion 644’ is used to install the focus magnet 621’, the frame 64’ includes an anti-shake frame 642’ and a focus frame 641’, the first frame portion 643’ and the frame connecting portion 645’ form an “L”-shaped anti-shake frame 642’, the second frame portion 644’ forms a focus frame 641’, and the anti-shake frame 642’ and the focus frame 641’ are connected by an integrated molding method. Further, as shown in FIG23A , the focus magnet 621’ is fixed to the outer side surface of the frame 64’, and at least one anti-shake magnet 661’ (the first anti-shake magnet 6611’ and the second anti-shake magnet 6612’) is fixed to the top surface of the frame 64’. In other words, the first anti-shake magnet 6611’, the second anti-shake magnet 6612’ and the focus magnet 621’ are respectively arranged on the three sides of the light turning element 30’, wherein the first anti-shake magnet 6611’ and the focus magnet 621’ are relatively arranged on the two long sides of the light turning element 30’. It should be understood that the light turning element 30’ is in the shape of a long strip, and from the direction of the light incident on the optical lens 10’, it has two opposite long sides and two opposite short sides.

It should be understood that in the present application, the first anti-shake coil 6621' and the second anti-shake coil 6622' are arranged above the first anti-shake magnet 6611' and the second anti-shake magnet 6612', and the focus coil 622' is located on the outside of the focus magnet 621'. In this way, the first anti-shake coil 6621' and the second anti-shake coil 6622' can be directly electrically connected to the chip circuit board 42' of the photosensitive component 40' upward, while the focus coil 622' is electrically connected to the photosensitive component 40' from the outside. The magnet-coil setting method of the present application optimizes the electrical connection setting method of the camera module 1' and makes the electrical connection setting method simpler.

In the present application, the driving device 60' also includes a focus guide portion 65' and a focus magnetic suction member 63'. The focus guide portion 65' is arranged between the frame 64' and the fixed base 61' to maintain an air gap between the frame 64' and the fixed base 61', thereby reducing the resistance encountered by the frame 64' when it moves relative to the fixed base 61'. In a specific example, the focus guide portion 65' can be implemented as a guide rod 651', and the focus guide portion 65' includes two guide rods 651'. Specifically, the two guide rods 651' are vertically arranged between the second frame portion 644' of the frame 64' and the focus fixing portion 613' of the fixed base 61', so that the frame 64' and the fixed base 61' maintain a fixed gap in the horizontal direction. Furthermore, in this embodiment, two guide rods 651' are respectively arranged on both sides of the focus driving part 62', and the two guide rods 651' have the same size to avoid tilting between the frame 64' and the focus fixing part 613'.

The focusing magnetic member 63’ is fixed to the focusing fixing portion 613’ of the fixed base 61’ by being attached to the back of the focusing circuit board 623’, that is, in the width direction, the focusing magnet 621’, the focusing coil 622’, the focusing circuit board 623’ and the focusing magnetic member 63’ are arranged in sequence. Among them, the side of the focusing circuit board 623’ on which the focusing coil 622’ is arranged is the front side of the focusing circuit board 623’, and the other opposite side is the back side of the focusing circuit board 623’. The focusing magnetic member 63’ is made of a material suitable for being attracted by a magnet, and it is magnetically attracted to the focusing magnet 621’ so that the frame 64’ is adsorbed to the focusing fixing portion 613’ of the fixed base 61’ in the width direction. The frame 64’ and the focusing fixing portion 613’ of the fixed base 61’ clamp two guide rods 651’ in the width direction. The focusing magnetic member 63’ can be a material containing iron.

In other words, the focus guide portion 65’ is arranged between the second frame portion 644’ of the frame 64’ and the focus fixing portion 613’ of the fixed base 61’, the focus magnetic component 63’ is fixed to the focus fixing portion 613’, and the focus magnetic component 63’ and the focus magnet 621’ are magnetically attracted to each other so that the focus guide portion 65’ is clamped between the second frame portion 644’ of the frame 64’ and the focus fixing portion 613’ of the fixed base 61’.

In a specific example, two first guide rails 6131' extending in the height direction are formed on the inner side surface of the focus fixing part 613' opposite to the frame 64', and two second guide rails 646' extending in the height direction are formed on the outer side surface of the frame 64' opposite to the focus fixing part 613' (that is, the outer side surface of the second frame part 644'), and the two first guide rails 6131' and the two second guide rails 646' are respectively arranged correspondingly. Two guide rods 651' are respectively arranged between the two first guide rails 6131' and the two second guide rails 646', and are clamped between the frame 64' and the focus fixing part 613' under the magnetic attraction between the focus magnetic suction member 63' and the focus magnet 621'.

It is worth mentioning that in one example of the present application, the two guide rods 651’ may not be fixed, and they are only clamped by the frame 64’ and the focus fixing part 613’; in another example of the present application, the positions of the two guide rods 651’ may also be fixed, for example, they may be fixed to the fixed base 61’ by fixing the bottom end of the guide rod 651’ to the fixed base 61’ and/or fixing the top end of the guide rod 651’ to the upper cover 610’, or, the two guide rods 651’ are only restricted between the upper cover 610’ and the fixed base 61’ by the snap fit between the upper cover 610’ and the fixed base 61’, or, the two guide rods 651’ may be fixed to the frame 64’ or the focus fixing part 613’.

It is worth mentioning that in the above embodiment, since the light deflection element 30' disposed between the optical lens 10' and the photosensitive component 40' is relatively long, in order to reduce the overall size of the camera module 1', the frame 64' has an opening in the direction toward the light deflection element 30', so that the frame 64' is disposed around the light deflection element 30' in a "Π" shape. Therefore, only three sides of the frame 64' can be provided with the first anti-shake magnet 6611', the second anti-shake magnet 6612' and the focus magnet 621'. The first anti-shake magnet 6611' and the second anti-shake magnet 6612' need to be disposed perpendicularly to each other to achieve translation in two perpendicular directions. Therefore, one of the first anti-shake magnet 6611' and the second anti-shake magnet 6612' needs to be disposed on the short side of the driving device 60', and the other of the first anti-shake magnet 6611' and the second anti-shake magnet 6612' and the focus magnet 621' are disposed on the two opposite long sides of the driving device 60'.

Specifically, the first anti-shake magnet 6611’ is installed on the top surface of the first frame portion 643’ located on the long side of the driving device 60’, the second anti-shake magnet 6612’ is installed on the top surface of the frame connection portion 645’ located on the short side of the driving device 60’, and the focus magnet 621’ is installed on the outer side of the second frame portion 644’ located on the long side of the driving device 60’. The focus magnet 621’, the first anti-shake magnet 6611’, and the second anti-shake magnet 6612’ are flat rectangular parallelepipeds, and the side with the largest area of the focus magnet 621’ is perpendicular to the side with the largest area of the first anti-shake magnet 6611’, and the side with the largest area of the focus magnet 621’ is perpendicular to the side with the largest area of the second anti-shake magnet 6612’. Correspondingly, the plane where the focusing coil 622’ is located is perpendicular to the plane where the first anti-shake coil 6621’ is located and the plane where the second anti-shake coil 6622’ is located, respectively, wherein the plane where the focusing coil 622’ (or the first anti-shake coil 6621’, the second anti-shake coil 6622’) is located refers to the plane where its largest area is located.

Furthermore, in one example, the magnetic pole direction of the first anti-shake magnet 6611' is perpendicular to the magnetic pole direction of the second anti-shake magnet 6612'. The magnetic pole direction of the focusing magnet 621' is perpendicular to the plane where the magnetic pole directions of the first anti-shake magnet 6611' and the magnetic pole directions of the second anti-shake magnet 6612' are located, so that the driving direction of the focusing drive unit 62' is perpendicular to the driving direction of the anti-shake drive unit 66'. Wherein, in the present application, the magnetic pole direction of the magnet refers to the direction in which the S pole of the magnet points to the N pole. Correspondingly, the focusing coil 622', the first anti-shake coil 6621' and the second anti-shake coil 6622' are all runway-type coils, wherein the winding plane of the focusing coil 622' and the winding plane of the first anti-shake coil 6621' are perpendicular to each other, and the winding plane of the focusing coil 622' and the winding plane of the second anti-shake coil 6622' are perpendicular to each other.

It should be understood that in the present application, since the focusing magnet 621' and the first anti-shake magnet 6611' are respectively arranged on the side and top surface of the frame 64', and the focusing magnet 621' and the first anti-shake magnet 6611' have different sizes, in one example, in the width direction, the optical lens 10', the light turning element 30' and the photosensitive component 40' are eccentrically arranged in the driving device 60'.

Furthermore, the photosensitive component 40' also includes a connecting circuit board 44', which is fixed and electrically connected to the chip circuit board 42' to provide electrical conduction between the chip circuit board 42' and the external electronic device. The applicant found that when the photosensitive component 40' is driven by the driving device 60' to achieve movement, the connecting circuit board 44' will become one of the sources of resistance to the movement of the photosensitive component 40'. Therefore, in this application, the applicant further improves the connecting circuit board 44' of the photosensitive component 40' to reduce the resistance encountered by the photosensitive component 40' when it is driven to achieve chip anti-shake or chip focus.

As shown in Fig. 19A, Fig. 19B and Fig. 23A, the connection circuit board 44' includes an inner circuit board 441', an outer circuit board 443' and a flexible conduction mechanism 442' connecting the inner circuit board 441' and the outer circuit board 443'. The inner circuit board 441' is fixed to the chip circuit board 42' and electrically connected to the chip circuit board 42', the inner circuit board 441' is arranged on the inner side of the outer circuit board 443', the outer circuit board 443' is fixed to the driving device 60', and the flexible conduction mechanism 442' electrically connects the inner circuit board 441' and the outer circuit board 443', so that the chip circuit board 42' can be electrically connected to the external electronic device through the outer circuit board 443' connecting the circuit board 44'. It should be understood that the electrical conduction between the chip circuit board 42' and the inner circuit board 441' can be achieved by arranging an electrical connection medium such as solder paste between the chip circuit board 42' and the inner circuit board 441'.

In one example of the present application, the inner circuit board 441' is disposed on the back side of the chip circuit board 42', wherein the side of the chip circuit board 42' facing the light deflection element 30' is the front side, and the side of the chip circuit board 42' away from the light deflection element 30' is the back side, and the photosensitive chip 41' is installed on the front side of the chip circuit board 42'. In other words, the inner circuit board 441' is disposed above the chip circuit board 42', and the inner circuit board 441' is disposed between the chip circuit board 42' and the frame cover 640'. Further, the outer circuit board 443' and the flexible conductive mechanism 442' are also disposed above the chip circuit board 42', and the outer circuit board 443' and the flexible conductive mechanism 442' are also disposed between the chip circuit board 42' and the frame cover 640'.

Further, in order to reduce the lateral size of the driving device 60', in a specific example of the present application, on at least one side of the chip circuit board 42', the size of the inner circuit board 441' is smaller than the size of the chip circuit board 42', that is, the size of the inner circuit board 441' in the length direction is smaller than the size of the chip circuit board 42' in the length direction and/or the size of the inner circuit board 441' in the width direction is smaller than the size of the chip circuit board 42' in the width direction. In other words, the area of the inner circuit board 441' can be smaller than the area of the chip circuit board 42'. In this way, in the horizontal direction, the connecting circuit board 44' can be made as small as possible, thereby minimizing the increase in the size of the driving device 60' in the horizontal direction.

Further, in the present application, the connection circuit board 44' extends laterally above the light deflection element 30' and above the anti-shake drive unit 66'. The connection circuit board 44' utilizes the structure that the anti-shake drive unit 66' is arranged on the peripheral side of the light deflection element 30', and the area of the connection circuit can be arranged larger, thereby achieving a better drag reduction effect. It should be understood that in the height direction, at least a portion of the connection circuit board 44' overlaps with the light deflection element 30'.

Specifically, as shown in FIG. 19A and FIG. 23A, the lateral extension direction of the connecting circuit board 44' is perpendicular to the length direction of the light deflection element 30'. In other words, the longest side of the connecting circuit board 44' is perpendicular to the length direction of the light deflection element 30'. Since the optical lens 10' and the photosensitive component 40' are arranged on the same side of the light deflection element 30' along the length direction, the space for arranging the connecting circuit board 44' in the length direction of the light deflection element 30' is relatively small. In order to maximize the use of the internal space of the camera module 1' and reduce the size of the camera module 1', the connecting circuit board 44' has a larger size in the length direction perpendicular to the light deflection element 30'.

Continuing to refer to FIG. 19A, FIG. 19B and FIG. 23A, the flexible conduction mechanism 442' electrically connects the inner circuit board 441' and the outer circuit board 443'. The flexible conduction mechanism 442' is easy to deform. When the driving device 60' drives the chip circuit board 42' fixed with the photosensitive chip 41' to move, the inner circuit board 441' fixed with the chip circuit board 42' is subject to less resistance from the flexible conduction mechanism 442'. In other words, since the flexible conduction mechanism 442' is easy to deform, the inner circuit board 441' fixed with the chip circuit board 42' is subject to less resistance from the flexible conduction mechanism 442'. The chip circuit board 42' and the inner circuit board 441' are easy to move relative to the outer circuit board 443', so the driving force of the driving device 60' can be designed to be smaller, so that the size of the driving device 60' can be reduced. It is worth mentioning that the flexible conductive mechanism 442' is easier to deform than the outer circuit board 443' or the inner circuit board 441'.

The flexible conductive mechanism 442' includes at least two flexible conductive arms 4421', which extend between the inner circuit board 441' and the outer circuit board 443' and connect the inner circuit board 441' and the outer circuit board 443'. The flexible conductive arms 4421' can electrically connect the inner circuit board 441' and the outer circuit board 443'. In one example of the present application, the flexible conductive mechanism 442' may include two flexible conductive arms 4421' arranged on opposite sides of the inner circuit board 441' along the width direction; in another example of the present application, as shown in FIG. 23A, the flexible conductive mechanism 442' may include four flexible conductive arms 4421', wherein two flexible conductive arms 4421' are arranged on one side of the inner circuit board 441' along the width direction, and the other two flexible conductive arms 4421' are arranged on the other side of the inner circuit board 441' along the width direction. In other words, the extension direction of the flexible conductive mechanism 442' is perpendicular to the length direction of the light turning element 30'.

Furthermore, the flexible conductive arm 4421' may include one or more flexible electrical connectors. When the number of flexible electrical connectors is designed to be larger, more conductive circuits can be provided between the inner circuit board 441' and the outer circuit board 443'. Specifically, the number of flexible electrical connectors in the flexible conductive arm 4421' is determined according to the circuit requirements of the photosensitive chip 41'.

Continuing with reference to FIGS. 19A and 19B , in an example of the present application, the external circuit board 443’ is directly or indirectly fixed to the frame 64’. For example, the external circuit board 443’ may be directly fixed to the top surface of the frame 64’, or the external circuit board 443’ is fixed to the bottom surface of the frame cover 640’ and thus indirectly fixed to the frame 64’, or the external circuit board 443’ is clamped by the frame cover 640’ and the frame 64’ and fixed between the frame cover 640’ and the frame 64’. The outer circuit board 443’ is higher than the inner circuit board 441’, that is, the top surface of the outer circuit board 443’ is higher than the top surface of the inner circuit board 441’. Furthermore, the bottom surface of the outer circuit board 443’ may also be higher than the bottom surface of the inner circuit board 441’. In this way, there is an air gap between the inner circuit board 441’ and the frame cover 640’, and there is an air gap between the outer circuit board 443’ and the chip circuit board 42’, so that the inner circuit board 441’ and the chip circuit board 42’ will not rub against the frame cover 640’ or the outer circuit board 443’ during movement, thereby reducing the resistance to movement. In this example, the flexible conductive arm 4421′ is inclined to connect the inner circuit board 441′ and the outer circuit board 443′, wherein the end of the flexible conductive arm 4421′ connected to the outer circuit board 443′ is higher than the end connected to the inner circuit board 441′, and during the horizontal movement of the chip circuit board 42′, the possibility of friction between the flexible conductive arm 4421′ and the chip circuit board 42′ is reduced.

In other words, in the present application, the outer circuit board 443’ can be fixed to a relatively fixed part of the driving device 60’, and the inner circuit board 441’ is fixed to the movable chip circuit board 42’, and the height of the inner circuit board 441’ can be maintained because the chip circuit board 42’ is fixed to the movable carrier 67’.

It is worth mentioning that in the present application, from a top view, the outer circuit board 443' and the inner circuit board 441' both have a substantially rectangular peripheral shape, wherein the outer circuit board 443' has a through hole, which is suitable for being a rectangular through hole, and the size of the through hole is larger than the size of the inner circuit board 441', so that the inner circuit board 441' and the flexible conductive mechanism 442' are arranged in the through hole. In order to optimize the size of the camera module 1', the chip circuit board 42' has a notch so that the optical lens 10' can extend from the notch, and accordingly, the outer circuit board 443' is provided with a notch at a corresponding position, so that the outer circuit board 443' is roughly "C" shaped.

Further, referring to Fig. 19A and Fig. 23A, the connection circuit board 44' further includes a connection belt 444', which is fixed to one side of the external circuit board 443' and electrically connected to the external circuit board 443', and the circuit board assembly is electrically connected to the external mobile electronic device through the connection belt 444'. It is worth mentioning that the connection belt 444' can be a flexible circuit board or a hard-soft board, so that the connection belt 444' can be bent to adapt to the space inside the driving device 60'.

Specifically, the inner circuit board 441’, the outer circuit board 443’ and the flexible conductive mechanism 442’ are arranged between the chip circuit board 42’ and the frame cover 640’, that is, the inner circuit board 441’, the outer circuit board 443’ and the flexible conductive mechanism 442’ are arranged in the accommodating cavity formed between the frame cover 640’ and the frame 64’, and the connecting belt 444’ extends outward from the accommodating cavity formed between the frame cover 640’ and the frame 64’, and finally extends out of the accommodating cavity formed by the upper cover 610’ and the fixed base 61’ to be electrically connected to the external electronic device.

Considering that the connection circuit board 44' will move in the height direction along with the chip circuit board 42' under the driving of the focus driving unit 62', in order to avoid the connection strip 444' from extending outwards and causing a large resistance in the height direction to the connection circuit board 44', a portion of the connection strip 444' is Bended in the driving device 60'.

In a specific example, the connection belt 444' extends outward and downward from the side of the outer circuit board 443' away from the focus driving part 62', and a part of the connection belt 444' is arranged below the frame 64' in a horizontally bent form. Specifically, a part of the connection belt 444' is arranged below the first frame part 643' in a horizontally bent form. That is, the connection belt 444' extends outward and downward from one side of the outer circuit board 443', and a part of the connection belt 444' is arranged in the driving device 60' in a horizontally bent form. Further, the bent portion can be referred to as a bent portion 4442', and therefore, the connection belt 444' includes an extension portion 4441', a bent portion 4442' and an output portion 4443' which are connected in sequence, the extension portion 4441' extending outward and downward from a side of the external circuit board 443' away from the focus drive unit 62', the bent portion 4442' electrically connects the extension portion 4441' and the output portion 4443' and is disposed below the first frame portion 643' of the frame 64', the output portion 4443' extends outward from the bent portion 4442' to extend out of the drive device 60', and the connection circuit board 44' is electrically connected to the external electronic device through the output portion 4443'. The bent portion 4442' is bent in the horizontal direction, so that when the photosensitive component 40' is driven by the focus drive unit 62' to move in the height direction, the bent portion 4442' can be stretched or folded to cooperate, so that the resistance generated by the connection belt 444' in the height direction is reduced.

It is worth mentioning that a part of the connecting belt 444’ is arranged below the frame 64’, which means that a part of the connecting belt 444’ is lower than any part of the frame 64’, and it is not necessary for a part of the connecting belt 444’ to be completely below the lowest point of the frame 64’.

Since the connection belt 444' extends outward from the side of the external circuit board 443' away from the focus driving part 62', there is a receiving space between the first frame part 643' of the frame 64' away from the focus driving part 62' and the base body 611' of the fixed base 61' to accommodate the bent part of the connection belt 444', that is, a part of the connection belt 444' is arranged in the receiving space in the form of a horizontal bend, and the bent part 4442' is arranged in the form of a horizontal bend in the receiving space. Correspondingly, as shown in FIG. 22, the base side wall 612' extending upward from the side of the base body 611' away from the focus driving part 62' has an opening to provide the lead-out part 4443' of the connection belt 444' to extend toward the outside of the fixed base 61'.

It is worth mentioning that the lead-out portion 4443' of the connection circuit board 44' can be fixed to the fixed base 61' or the upper cover 610', so that the extension portion 4441' and the bent portion 4442' located inside the driving device 60' are not affected by external factors, and the resistance of the driving device 60' from the photosensitive component 40' is prevented from further increasing. Furthermore, the focus circuit board 623' can be electrically connected to the lead-out portion 4443' of the connection circuit board 44', so as to be electrically connected to the chip circuit board 42'.

Furthermore, an example of a manufacturing method of the connecting circuit board 44' is given. In the present application, the connecting circuit board 44' can be formed by first forming an inner circuit board 441', an outer circuit board 443', a flexible conductive mechanism 442' and a connecting belt 444' respectively, and then connecting and fixing them at set positions respectively; the connecting circuit board 44' can also be formed by removing part of the structure from a flexible circuit board or a soft-hard combination board, for example, a circuit board is provided, the part of the circuit board where the flexible conductive mechanism 442' is predetermined to be formed is a flexible circuit board, and part of the structure in the part is removed to form a flexible conductive mechanism 442' connecting the inner circuit board 441' and the outer circuit board 443', thereby completing the manufacturing of the connecting circuit board 44'.
