With the gradual development of electronic equipment technology, people hope that the shooting performance of the mobile phone can be better and better. However, in the shooting process of the conventional mobile phone, the shot image is easily deformed or blurred due to external motion or shake, so that the user experience of the mobile phone is seriously affected. Therefore, how to set up a kind of stability better, be difficult for because of external motion or shake and influence the shooting module of quality very important.

Disclosure of Invention

The application provides an optical lens, a camera module and electronic equipment which are not easy to influence shooting due to external motion or shake.

In a first aspect, embodiments of the present application provide an optical lens. The optical lens comprises a motor, a first lens and a self-locking component. The motor includes a driving member and a moving bracket. The first lens is mounted on the movable support. The driving piece is used for driving the movable support to move along the optical axis direction of the optical lens. In the present application, the moving rack includes a first moving rack and a second moving rack. The optical axis direction of the optical lens is the X-axis direction. In addition, the optical axis refers to an axis passing through the center of each lens.

The self-locking assembly comprises a base, a rotating piece, a force application piece, an elastic piece and a limiting block. The base and the movable support are arranged at intervals. The rotating piece is rotatably connected to the base. One end of the elastic piece is connected with the rotating piece, and the other end of the elastic piece is connected with the base.

The limiting block is located between the rotating piece and the movable support. The limiting block is fixed on the rotating piece. In one embodiment, the limiting block is fixed to the rotating member by adhesive tape or glue. In one embodiment, the limiting block and the rotating member are integrally formed.

The force application member is used for applying force to the rotating member when the power is on. The energizing condition of the force application member can be determined according to whether the movable bracket moves relatively. For example, when the moving bracket is not relatively moved, the urging member is not energized. When the movable support moves relatively, the force application piece is electrified. In addition, when the moving bracket does not move relatively, the moving bracket is at a target position. The target position may be a focusing position of the movable support, or may be a fixed position of the movable support when the optical lens is not started to shoot.

When the force application piece is not electrified, the limiting block is contacted with the movable support under the elasticity of the elastic piece, and static friction force can be generated between the limiting block and the movable support. It is understood that the stopper applies pressure to the moving bracket when the stopper contacts the moving bracket under the elastic force of the elastic member. At this time, when the moving bracket has a tendency to move relatively, the moving bracket generates a static friction force. Therefore, the limiting block can press the movable support under the elasticity of the elastic piece.

When the force application part is electrified, the rotating part is driven to overcome the elasticity of the elastic part, and the limiting block is driven to rotate, so that the limiting block is separated from the movable support.

It can be understood that the power-on condition of the force application piece is controlled to control whether the limiting block is pressed on the movable bracket or separated from the movable bracket, so that the movable bracket is controlled to be in a locking state or an unlocking state. At this time, when the moving bracket is in a locked state, the first lens mounted to the moving bracket is preferably stabilized. Thus, when the optical lens is in the shooting process, the first lens is not easy to move due to external shake or vibration, the image shot by the optical lens is not easy to deform or blur, and the quality of the image shot by the optical lens is better. In particular, when a user takes a picture during a movement, the effect of the image taken by the optical lens is better.

In addition, when the movable support is in a locking state, the movable support can avoid collision with other parts in the optical lens, so that the collision risk of the movable support is reduced. In addition, when the movable support comprises a first movable support and a second movable support, the first movable support and the second movable support are locked, so that the collision phenomenon of the first movable support and the second movable support can be avoided, and the collision risk of the first movable support and the second movable support is reduced.

In addition, when the movable support is in a locking state, the movable support can avoid forced vibration. Forced vibration refers to vibration that occurs under the influence of a periodic external force.

In one embodiment, the connection position of the limiting block and the rotating member is a first position. The force application position of the force application piece to the rotating piece is a second position. The rotational position of the rotational member is located between the first position and the second position. At this time, the limiting block, the rotating member and the force application member form a lever structure. The limiting block and the force application piece are positioned at two sides of the rotating position of the rotating piece, and the limiting block and the force application piece are not easy to interfere with each other in movement, so that the reliability of the self-locking assembly is ensured.

In one embodiment, the first position is a first distance from the rotational position of the rotational member. The second position is a second distance from the rotational position of the rotational member. The first distance is greater than the second distance. At this time, when the force application member is electrified, the force application member pulls the rotating member to rotate at a larger angle, and the distance between the limiting block and the movable bracket is also larger. Thus, when the movable support moves along the X-axis direction, interference with the limiting block is not easy to occur.

In one embodiment, the force application member is a shape memory alloy. The direction of the acting force is the same as the pressure applied to the movable bracket by the limiting block.

It can be understood that the direction of the force is set to be the same as the pressure applied to the moving bracket by the limiting block, so that the force application member and the moving bracket are positioned on the same side of the rotating member. At this time, the extending direction of the urging member may have an overlapping region with the extending direction of the movable bracket in the Y-axis. Thus, when the length of the urging member is increased to a large extent, the urging member does not increase the length of the optical lens in the Y-axis direction. In addition, when the length of the force application member is greatly increased, the contraction length of the force application member under the power on is also large, at this time, the angle by which the force application member pulls the rotation member to rotate is also large, and the distance by which the limiting block is separated from the movable bracket is also large. Thus, when the movable support moves along the X-axis direction, interference with the limiting block is not easy to occur.

In one embodiment, the material of the rotating member is a conductive material. The self-locking assembly further comprises a first circuit board, a connector and a rotating shaft. The first circuit board is arranged at intervals with the movable support. The first circuit board comprises a first pin and a second pin which are arranged at intervals. The connector is fixed on the first circuit board and is electrically connected with the first pin. One end of the force application piece is fixed to the connector, and the other end of the force application piece is fixed to the rotating piece. One end of the rotating shaft is fixed on the base, and the other end of the rotating shaft is rotatably connected with the rotating piece. The rotating shaft is electrically connected to the second pin. At this time, the first circuit board, the connector, the force application member, the rotating shaft, and the rotating member form a current path. It will be appreciated that the shaft can be used to both rotate the rotatable member relative to the base and as part of the current path. The rotating shaft has the effect of 'one object with multiple functions'. In addition, the rotating piece can be used for driving the limiting block to rotate and can be used as a part of a current path. The rotating member also has the effect of "one-thing-multiple-use".

In one embodiment, the elastic member is located at a side of the rotating member away from the limiting block, and the elastic member is disposed opposite to the limiting block.

It can be understood that, through will the elastic component set up in the one side that rotates the piece and keep away from the stopper, thereby when moving the support along the X axle direction removes, the elastic component be difficult for with the movable support takes place to interfere, thereby guarantee the reliability of auto-lock subassembly.

In addition, through setting up the elastic component with the stopper is relative, thereby when the application of force spare is to the rotation piece exerts the pulling force, the elastic component is difficult to take place to interfere with the application of force spare, thereby guarantees the reliability of auto-lock subassembly.

In one embodiment, the connection position of the limiting block and the rotating member is a first position. The force application position of the force application piece to the rotating piece is a second position. The first position and the second position are located on the same side of the rotational position of the rotational member. At this time, the force application distance of the force application piece to the limiting block is shorter, and the limiting block is easier to separate from the movable support.

In one embodiment, the material of the rotating member is a magnetic material. The force application piece comprises a magnetic piece and a coil wound on the surface of the magnetic piece. One end of the magnetic piece is fixed on the base, and the other end faces the rotating piece. The direction of the force is opposite to the pressure applied to the movable bracket by the limiting block. At this time, the force application member and the moving bracket are located on different sides of the rotating member. When the movable support moves along the X-axis direction, the movable support is not easy to interfere with the force application piece. In addition, the magnetic field generated by the force application member does not easily influence the movement of the movable support along the X-axis direction.

In one embodiment, the elastic member and the force application member are located on the same side of the rotating member, and the elastic member and the force application member are located on two sides of the rotating position of the rotating member.

It is understood that the elastic member and the force application member are disposed on the same side of the rotating member, so that the elastic member is not easy to collide with or interfere with the moving bracket during the moving process of the moving bracket.

In addition, by providing the elastic member and the urging member on both sides of the rotational position of the rotational member, the elastic member is less likely to interfere with the urging member when the urging member is urging the rotational member.

In one embodiment, the motor further comprises a base plate, a fixed bracket and a guide rail. The fixed support is arranged opposite to the base plate. One end of the guide rail is fixed on the base plate, and the other end of the guide rail is fixed on the fixed support. The movable support is located between the base plate and the fixed support and is movably connected to the guide rail. The optical lens further includes a second lens. The second lens is mounted on the fixed support. The second lens is positioned on the object side of the first lens.

It can be understood that the lens is taken as a boundary, and the side where the object is located is the object side. The surface of the lens close to the object side is called the object side. The side on which the image of the subject is located is the image side. The surface of the lens close to the image side is called the image side.

It is understood that the second lens is disposed on the object side of the first lens, so that the light with a large angle of view is received to a large extent by the second lens. In this case, the angle of view of the optical lens can be greatly increased.

In one embodiment, the optical lens further comprises a housing. The base plate and the fixing support are located inside the shell and fixed to the shell. The movable brackets comprise first movable brackets and second movable brackets which are arranged at intervals. The first lens is fixed on the first moving support and the second moving support. The driving piece comprises a first magnet, a first coil, a second magnet and a second coil. The first magnet is fixed on the first movable bracket. The first coil is fixed on the inner side of the shell and faces the first magnet. The second magnet is fixed on the second movable bracket. The second coil is fixed on the inner side of the shell and faces the second magnet.

It is understood that when the moving frames are provided as a first moving frame and a second moving frame which are disposed at intervals, the first lenses mounted to the first moving frame and the second moving frame can be individually moved in the X-axis direction. In this case, the degree of freedom of the optical design of the optical lens is better.

In one embodiment, the optical lens further comprises a lens circuit board. The lens circuit board is electrically connected to the first coil and the second coil. At this time, the lens circuit board can transmit signals to the first coil and the second coil.

In one embodiment, the optical lens further comprises a hall sensor and a detection magnet. The detection magnet is fixed on the movable support. The hall sensor is used for detecting the magnetic field intensity when the detection magnet is at different positions.

It is understood that when the moving carriage moves in the X-axis direction toward the target position, the moving carriage is liable to appear not to move to the target position. In the embodiment, the Hall sensor is used for measuring the magnetic field intensity of the position of the detection magnet, and judging whether the magnetic field intensity is equal to the preset magnetic field intensity of the target position. When the magnetic field intensity is not equal to the preset magnetic field intensity at the target position, the driving piece can continuously push the movable support to move along the X-axis direction, so that the movable support can accurately move to the target position. Therefore, by arranging the Hall sensor and the detection magnet, the accuracy of the movement of the movable support along the X-axis direction can be remarkably improved.

In one embodiment, the optical lens further comprises a prism motor and a reflector. The reflecting piece is rotatably connected to the prism motor. The reflecting piece is used for reflecting the ambient light so as to enable the ambient light to be transmitted to the first lens. The reflecting member of the present embodiment will be described by taking a triangular prism as an example.

It can be understood that the optical lens is easy to shake in the process of collecting the ambient light, and at this time, the transmission path of the ambient light is easy to deviate, so that the image shot by the optical lens is poor. In this embodiment, when the transmission path of the ambient light deflects, the prism motor may drive the prism to rotate, so as to adjust the transmission path of the ambient light by using the prism, reduce or avoid the deflection of the transmission path of the ambient light, and further ensure that the optical lens has a better shooting effect. Therefore, the reflecting member can play an optical anti-shake effect.

The force application piece is used for applying force to the limiting block when the power is on. The energizing condition of the force application member can be determined according to whether the movable bracket moves relatively. For example, when the moving bracket is not relatively moved, the urging member is not energized. When the movable support moves relatively, the force application piece is electrified. In addition, when the movable support is not relatively moved, the movable support is in a fixed position. The fixed position is a position of the movable support when the optical lens is not started to shoot.

When the force application piece is not electrified, part of the limiting block is positioned in the first through hole. At this time, the hole wall of the first through hole can limit the movement of the limiting block.

When the force application part is electrified, the limiting block is driven to overcome the elastic force of the elastic part and move out of the first through hole.

It can be understood that the power-on condition of the force application piece is controlled to control whether the limiting block is positioned in the first through hole or moved out of the first through hole, so that the movable support is controlled to be in a locking state or an unlocking state. At this time, when the moving bracket is in a locked state, the first lens mounted to the moving bracket is preferably stabilized.

In addition, when the movable support is in a locking state, the movable support can avoid collision with other parts in the optical lens, so that the collision risk of the movable support is reduced.

The first fixing portion comprises a first conductive segment, an insulating segment and a second conductive segment. One end of the insulating section is connected with the first conductive section, and the other end of the insulating section is connected with the second conductive section. The first conductive segment is connected to one end of the force application member. The second conductive segment is connected to the connection portion. The first conductive segment is electrically connected to the first pin. The second conductive segment is electrically connected to the second pin. In this way, the first circuit board, the first conductive segment, the force application member, the second fixing portion, the connecting portion, and the second conductive segment form a current path.

It can be appreciated that the elastic member can be used to drive the stopper to extend into or out of the first through hole, and can also be used as a part of the current path. The elastic piece has the effect of 'one-object-multiple-use'.

It is understood that when the moving frames are provided as a first moving frame and a second moving frame which are disposed at intervals, the first lenses mounted to the first moving frame and the second moving frame can be individually moved in the X-axis direction. At this time, the optical design freedom of the optical lens is better, and the matching movement among the plurality of first lenses is more flexible.

Referring to fig. 3 in conjunction with fig. 2, fig. 3 is a schematic partial cross-sectional view of the electronic device 1 shown in fig. 1 at line A-A. The host circuit board 90 is fixed inside the electronic device 1. Specifically, the host circuit board 90 may be fixed to a side of the screen 80 facing the rear cover 72. In other embodiments, when the housing 70 includes a midplane, the motherboard 90 may be secured to a surface of the midplane facing the back cover 72.

It is understood that the host circuit board 90 may be a hard circuit board, a flexible circuit board, or a combination of a hard and soft circuit board. The host circuit board 90 may be an FR-4 dielectric board, a Rogers dielectric board, a mixed dielectric board of FR-4 and Rogers, or the like. Here, FR-4 is a code of a flame resistant material grade, and the Rogers dielectric board is a high frequency board. In addition, the host circuit board 90 may be used to set up chips. For example, the chip may be a central processing unit (central processing unit, CPU), a graphics processor (graphics processing unit, GPU), a general purpose memory (universal flash storage, UFS), or the like.

Referring to fig. 3 again, and referring to fig. 2, the camera module 100 is fixed inside the electronic device 1. Specifically, the camera module 100 is fixed to a side of the screen 80 facing the rear cover 72. In other embodiments, when the housing 70 includes a midplane, the camera module 100 may be secured to a surface of the midplane facing the back cover 72.

In addition, the host circuit board 90 is provided with a relief space 91. The shape of the escape space 91 is not limited to the rectangular shape illustrated in fig. 1 and 2. At this time, the shape of the host circuit board 90 is not limited to the "+" type as illustrated in fig. 1 and 2. The camera module 100 is located in the avoidance space 91. In this way, in the Z-axis direction, the camera module 100 and the host circuit board 90 have an overlapping area, so that an increase in thickness of the electronic device 1 due to stacking of the camera module 100 on the host circuit board 90 is avoided. In other embodiments, the host circuit board 90 may not be provided with the avoidance space 91. At this time, the camera module 100 may be stacked on the host circuit board 90 or spaced apart from the host circuit board 90.

In the present embodiment, the camera module 100 is electrically connected to the host circuit board 90. Specifically, the camera module 100 is electrically connected to the CPU through the host circuit board 90. When the CPU receives the instruction from the user, the CPU can send a signal to the camera module 100 through the host circuit board 90 to control the camera module 100 to take an image or record a video. In other embodiments, when the electronic device 1 is not provided with the host circuit board 90, the camera module 100 may also directly receive the instruction of the user, and take an image or record a video according to the instruction of the user.

Referring again to fig. 3, the rear cover 72 is provided with a through hole 73. The through hole 73 communicates the inside of the electronic apparatus 1 to the outside of the electronic apparatus 1. The electronic device 1 further comprises a camera trim 61 and a second cover 62. A part of the camera trim 61 may be fixed to the inner surface of the rear cover 72, and a part of the camera trim 61 contacts the wall of the through hole 73. The second cover plate 62 is fixedly connected to the inner surface of the camera trim 61. The camera trim 61 and the second cover 62 separate the inside of the electronic apparatus 1 from the outside of the electronic apparatus 1, thereby preventing external water or dust from entering the inside of the electronic apparatus 1 through the through hole 73. The second cover 62 is made of transparent material. Such as glass or plastic. At this time, ambient light outside the electronic device 1 can pass through the second cover plate 62 into the inside of the electronic device 1. The camera module 100 collects ambient light entering the interior of the electronic device 1.

It will be appreciated that the shape of the through hole 73 is not limited to the circular shape illustrated in fig. 1 and 2. For example, the shape of the through hole 73 may be elliptical or other irregular patterns.

In other embodiments, the camera module 100 may also collect ambient light that passes through the rear cover 72. Specifically, the rear cover 72 is made of a transparent material. Such as glass or plastic. The surface of the rear cover 72 facing the inside of the electronic device 1 is partially coated with ink and partially uncoated with ink. At this time, the areas not coated with ink form light-transmitting areas. When the ambient light enters the electronic device 1 through the light-transmitting area, the camera module 100 collects the ambient light. It is to be understood that the electronic device 1 of the present embodiment may not be provided with the through hole 73, or may not be provided with the camera trim 61 and the second cover 62. The electronic device 1 has better integrity and lower cost.

As shown in fig. 4 and 5, fig. 4 is a schematic structural diagram of the image capturing module 100 of the electronic device 1 shown in fig. 1. Fig. 5 is a partially exploded schematic view of the camera module 100 shown in fig. 4. The camera module 100 includes an optical lens 10, a module circuit board 20, a photosensitive chip 30, and an optical filter 40. The optical axis direction of the optical lens 10 is the same as the optical axis direction of the image capturing module 100.

The module circuit board 20 is fixed on the light-emitting side of the optical lens 10, that is, the module circuit board 20 is located on the image side of the optical lens 10. Fig. 4 illustrates a shape in which the module circuit board 20 and the optical lens 10 substantially enclose a rectangular parallelepiped. Referring to fig. 3, the module circuit board 20 may be electrically connected to the host circuit board 90. In this way, signals can be transmitted between the host circuit board 90 and the module circuit board 20.

The module circuit board 20 may be a hard circuit board, a flexible circuit board, or a soft-hard combined circuit board. In addition, the module circuit board 20 may be an FR-4 dielectric board, a Rogers (Rogers) dielectric board, a mixed dielectric board of Rogers and FR-4, or the like.

Referring to fig. 3 again, the photosensitive chip 30 is fixed on the side of the module circuit board 20 facing the optical lens 10. The photosensitive chip 30 is electrically connected to the module circuit board 20. Thus, after the light sensing chip 30 collects the ambient light, the light sensing chip 30 generates a signal according to the ambient light, and transmits the signal to the host circuit board 90 through the module circuit board 20.

In one embodiment, the photosensitive chip 30 may be mounted on the module circuit board 20 by Chip On Board (COB) technology. In other embodiments, the photosensitive chip 30 may also be packaged on the module circuit board 20 by Ball Grid Array (BGA) technology or Land Grid Array (LGA) technology.

In other embodiments, the module circuit board 20 also has electronic components or other chips (e.g., driver chips) mounted thereon. Electronic components or other chips are provided around the periphery of the photosensitive chip 30. The electronic component or other chip is used for assisting the photosensitive chip 30 to collect the ambient light and assisting the photosensitive chip 30 to process the collected ambient light.

In other embodiments, a reinforcing plate is disposed on a side of the module circuit board 20 away from the photosensitive chip 30. For example, the reinforcing plate is a steel plate. The reinforcing plate can improve the strength of the module circuit board 20.

In other embodiments, the module circuit board 20 may also be partially provided with a sink, and the photosensitive chip 30 may be mounted in the sink. In this way, the photosensitive chip 30 and the module circuit board 20 have an overlapping area in the X-axis direction, and at this time, the image pickup module 100 can be set thinner in the X-axis direction.

Referring to fig. 3 again, the optical filter 40 is located at a side of the photosensitive chip 30 facing the optical lens 10. The optical filter 40 can be used for filtering stray light of the ambient light passing through the optical lens 10 and transmitting the filtered ambient light to the light sensing chip 30, so as to ensure better definition of the image captured by the electronic device 1. The filter 40 may be, but is not limited to, a blue glass filter. For example, the filter 40 may be a reflective infrared filter, or a two-pass filter (the two-pass filter may transmit both visible light and infrared light in the ambient light, or transmit both visible light and light of other specific wavelengths (e.g., ultraviolet light), or transmit both infrared light and light of other specific wavelengths (e.g., ultraviolet light).

Referring to fig. 6, fig. 6 is a partially exploded view of the optical lens 10 shown in fig. 5. The optical lens 10 includes a lens assembly 101 and a reflecting assembly 11. The optical axis direction of the lens assembly 101 is the same as the optical axis direction of the optical lens 10. The reflection assembly 11 is fixed to the light incident side of the lens assembly 101. Fig. 5 illustrates a shape in which the reflecting member 11 and the lens member 101 substantially enclose a rectangular parallelepiped. The reflection assembly 11 is used for reflecting ambient light so as to transmit the ambient light into the lens assembly 101. In this embodiment, the reflection assembly 11 may be used to reflect the ambient light propagating along the Z-axis direction to the ambient light propagating along the X-axis direction. In other embodiments, the reflective component 11 may be used to reflect ambient light propagating in the Z-axis direction to ambient light propagating in other directions.

The reflecting component 11 includes a prism motor 111 and a reflecting member 112. The prism motor 111 is fixed to the light incident side of the lens assembly 101. The reflecting member 112 is located inside the prism motor 111. The reflecting member 112 may be a triangular prism or a reflecting mirror. The reflecting member 112 of the present embodiment is described taking a triangular prism as an example. Note that, the reference numerals of the triangular prisms are the same as those of the reflecting member 112 hereinafter.

Referring to fig. 6 again, the prism motor 111 is provided with a first light hole 1111. The first light transmission hole 1111 communicates the inside of the prism motor 111 to the outside of the prism motor 111. The shape of the first light transmitting holes 1111 is not limited to the rectangle illustrated in fig. 6. As shown in fig. 3, the first light transmitting hole 1111 is disposed opposite to the second cover plate 62. At this time, ambient light outside the electronic apparatus 1 can enter the inside of the prism motor 111 through the second cover plate 62, the first light-transmitting hole 1111.

Referring to fig. 3 again, the prism motor 111 is provided with a second light hole 1112. The second light hole 1112 communicates the inside of the prism motor 111 to the outside of the prism motor 111. The second light hole 1112 faces the lens assembly 101.

The prism 112 includes an entrance surface 1121, a reflection surface 1122, and an exit surface 1123. The reflection surface 1122 is connected between the light incident surface 1121 and the light emergent surface 1123. The light incident surface 1121 is disposed opposite to the first light transmitting hole 1111. The light-emitting surface 1123 is disposed opposite to the second light-transmitting hole 1112. At this time, when the ambient light enters the inside of the prism motor 111 through the first light transmitting hole 1111, the ambient light enters the prism 112 through the light incident surface 1121, and is reflected at the reflection surface 1122 of the prism 112. At this time, the ambient light propagating in the Z-axis direction is reflected to propagate in the X-axis direction. Finally, the ambient light is transmitted out of the prism 112 through the light-emitting surface 1123 of the prism 112, and is transmitted out of the prism motor 111 through the second light-transmitting hole 1112.

It can be appreciated that by providing the triple prism 112 inside the prism motor 111, the ambient light propagating in the Z-axis direction is reflected to propagate in the X-axis direction by the triple prism 112. In this way, the devices of the camera module 100 that receive the ambient light propagating in the X-axis direction can be arranged in the X-axis direction. Since the electronic apparatus 1 has a larger size in the X-axis direction, the arrangement of the devices in the camera module 100 in the X-axis direction is more flexible and simpler. In the present embodiment, the optical axis direction of the image capturing module 100 is the X-axis direction. In other embodiments, the optical axis direction of the image capturing module 100 may be the Y-axis direction.

Referring again to fig. 6, and in conjunction with fig. 3, a triple prism 112 may be rotatably coupled to a prism motor 111. In the present embodiment, the triangular prism 112 can rotate in the XZ plane with the Y axis as the rotation axis. The prism 112 can also rotate on the XY plane with the Z axis as the rotation axis. It can be appreciated that the camera module 100 is easy to shake during the process of collecting the ambient light, and at this time, the transmission path of the ambient light is easy to deflect, so that the image captured by the camera module 100 is poor. In this embodiment, when the transmission path of the ambient light is deflected, the prism motor 111 can drive the prism 112 to rotate, so that the transmission path of the ambient light is adjusted by using the prism 112, the deflection of the transmission path of the ambient light is reduced or avoided, and the camera module 100 is further ensured to have a better shooting effect. Thus, the reflection assembly 11 may have an optical anti-shake effect.

In other embodiments, the triple prism 112 may also be fixedly coupled to the prism motor 111 or may also be slidably coupled to the prism motor 111.

In the present embodiment, the lens assembly 101 has various arrangements. Several arrangements of the lens assembly 101 will be described in detail below in connection with the associated drawings.

Wherein, the housing 12 includes an upper cover 121 and a bottom plate 122. The upper cover 121 is mounted to the bottom plate 122. The upper cover 121 and the bottom plate 122 enclose a substantially rectangular parallelepiped. Note that the upper mark 122 in fig. 7 clearly marks the corresponding structure in the lower part in fig. 7. The upper part 122 of fig. 7 mainly illustrates that the bottom plate 122 and the upper cover 121 belong to the housing 12.

In addition, the upper cover 121 includes a right side plate 1212, an upper side plate 1215, and front and

rear side plates

The shape of the third light-transmitting hole 1211 is not limited to the rectangle illustrated in fig. 6 and 7. As shown in fig. 3, the third light-transmitting hole 1211 is disposed opposite to the second light-transmitting hole 1112. When the ambient light passes out of the reflective assembly 11 through the second light transmitting holes 1112, the ambient light propagates into the lens assembly 101 through the third light transmitting holes 1211.

It will be appreciated that the first magnet 145 forms a first drive member with the first coil 146. The second magnet 147 and the second coil 148 form a second driving member. The first driving member is for driving the first moving bracket 143 to move in the X-axis direction. The second driving member is used for driving the second moving bracket 144 to move along the X-axis direction. In other embodiments, the number of driving members is not limited to only two as shown in the present embodiment. The moving bracket is also not limited to the two illustrated in the present embodiment.

Wherein the substrate 13 has a plate-like structure. The substrate 13 is provided with fourth light transmission holes 131. The fourth light holes 131 penetrate through opposite surfaces of the substrate 13. As shown in fig. 6, the substrate 13 is fixed to a side of the housing 12 away from the third light-transmitting hole 1211. The substrate 13 and the housing 12 substantially enclose a rectangular parallelepiped. As shown in fig. 3 in combination, fig. 3 also illustrates that the substrate 13 is fixed to a side of the housing 12 away from the third light-transmitting hole 1211. The fourth light-transmitting hole 131 communicates the inside of the housing 12 to the outside of the housing 12. In addition, the photosensitive chip 30 and the optical filter 40 are both located in the fourth light hole 131, and the optical filter 40 is fixed on the wall of the fourth light hole 131. Thus, when the ambient light is transmitted to the inside of the case 12 through the third light transmitting hole 1211, the ambient light may be sequentially transmitted to the optical filter 40 and the photo-sensing chip 30 through the fourth light transmitting hole 131.

The plurality of guide rails 141 pass through the plurality of first slide holes 1433 in a one-to-one correspondence. The guide rail 141 can slide with respect to the wall of the first slide hole 1433.

As shown in connection with fig. 8, the first moving bracket 143 includes a first portion 1431 and a second portion 1432 connected to the first portion 1431. Note that the upper mark 1432 in fig. 8 clearly marks the corresponding structure in the lower part of fig. 8. The upper mark 1432 of fig. 8 mainly illustrates that the second portion 1432 and the first portion 1431 belong to the first moving bracket 143.

In addition, the first portion 1431 is provided with two first slide holes 1433. The first portion 1431 and the second portion 1432 together define two further first slide holes 1433. It can be appreciated that by providing the first moving bracket 143 as the first portion 1431 and the second portion 1432, the difficulty in assembling the plurality of guide rails 141 with the first moving bracket 143 is reduced.

Referring again to fig. 8, the first portion 1431 is provided with a second mounting hole 1434. The second mounting hole 1434 is disposed opposite the first mounting hole 1422.

The second moving bracket 144 is movably connected to the guide rail 141. Specifically, the second moving bracket 144 is provided with a plurality of second sliding holes 1443. The number of the second sliding holes 1443 is the same as the number of the guide rails 141. The plurality of guide rails 141 pass through the plurality of second sliding holes 1443 in a one-to-one correspondence. The guide rail 141 is slidable with respect to the wall of the second sliding hole 1443. It is understood that the second moving bracket 144 may move simultaneously with the first moving bracket 143 or may not move simultaneously with the first moving bracket 143.

The lens circuit board 16 may be a hard circuit board, a flexible circuit board, or a combination of a hard and soft circuit board. In addition, the lens circuit board 16 may be an FR-4 dielectric board, a Rogers dielectric board, a mixed dielectric board of Rogers and FR-4, or the like.

Referring to fig. 11 again, the first coil 146 is electrically connected to the lens circuit board 16. At this time, the first coil 146 may be electrically connected to the module circuit board 20 through the lens circuit board 16. Thus, when the module circuit board 20 transmits a current signal to the first coil 146 through the lens circuit board 16, the first coil 146 is energized, and the first magnet 145 can generate an ampere force along the negative X-axis direction or the positive X-axis direction under the action of the first coil 146. At this time, the first magnet 145 pushes the first moving bracket 143 to move in the X-axis negative direction or the X-axis positive direction under an ampere force. In this way, the first lens 151 fixed to the first moving bracket 143 can also move in the X-axis negative direction or the X-axis positive direction.

It will be appreciated that by changing the direction of the current signal on the first coil 146, or by locating the S-pole or N-pole of the first magnet 145, the first magnet 145 can generate an ampere force in the negative X-axis direction or the positive X-axis direction when the first coil 146 is energized. At this time, the first magnet 145 can push the first moving bracket 143 to move in the X-axis negative direction or the X-axis positive direction under an ampere force.

Referring again to fig. 11, and in conjunction with fig. 10, the second coil 148 is electrically connected to the lens circuit board 16. At this time, the second coil 148 may be electrically connected to the module circuit board 20 through the lens circuit board 16. Thus, when the module circuit board 20 transmits a current signal to the second coil 148 through the lens circuit board 16, the second coil 148 is energized, and the second magnet 147 can generate an ampere force in the negative X-axis direction or the positive X-axis direction. At this time, the second magnet 147 pushes the second moving bracket 144 to move in the X-axis negative direction or the X-axis positive direction under an ampere force. In this way, the first lens 151 fixed to the second moving bracket 144 can also move in the X-axis negative direction or the X-axis positive direction.

It will be appreciated that by changing the direction of the current signal on the second coil 148, or by positioning the S-pole or N-pole of the second magnet 147, the second magnet 147 can generate an ampere force in the negative X-axis direction or the positive X-axis direction when the second coil 148 is energized. At this time, the second magnet 147 can push the second moving bracket 144 to move in the X-axis negative direction or the X-axis positive direction under an ampere force.

In other embodiments, the lens assembly 101 may not include the lens circuit board 16. At this time, the first coil 146 and the second coil 148 may be electrically connected to the module circuit board 20 through wires, respectively.

Referring to fig. 12, fig. 12 is a schematic diagram illustrating a part of the structure of the camera module 100 shown in fig. 4 in the first embodiment. The first portion 1431 of the first moving bracket 143 is provided with a sink 1436. The opening of the recess 1436 faces the lens circuit board 16. The detection magnet 172 is disposed in the sink 1436. Thus, the detecting magnet 172 does not increase the thickness of the image capturing module 100 in the Z-axis direction.

In addition, the hall sensor 171 is fixed to a side of the lens circuit board 16 facing the first moving bracket 143, and is electrically connected to the lens circuit board 16. At this time, the hall sensor 171 is electrically connected to the module circuit board 20 through the lens circuit board 16. The hall sensor 171 is used to detect the magnetic field strength when the detection magnet 172 is at different positions.

In addition, the second moving bracket 144 may be provided with a sink. A detection magnet is arranged in the sinking groove. The lens circuit board 16 is provided with a hall sensor. The hall sensor is used to detect the magnetic field strength of the detection magnet on the second moving bracket 144.

It will be appreciated that when a user desires to focus the camera module 100, the lens circuit board 16 transmits a current signal to the first coil 146. The first magnet 145 pushes the first moving bracket 143 to move in the positive X-axis direction or the negative X-axis direction with respect to the rail 141 under an ampere force. At this time, the first moving bracket 143 is liable to appear not to move to the target position. In the present embodiment, the hall sensor 171 is used to measure the magnetic field intensity at the position of the detection magnet 172, and determine whether the magnetic field intensity is equal to the preset magnetic field intensity at the target position. When the magnetic field strength is not equal to the preset magnetic field strength at the target position, the hall sensor 171 feeds back to the module circuit board 20 through the lens circuit board 16. At this time, the module circuit board 20 can provide the compensation current signal to the first coil 146, so that the first moving bracket 143 is accurately moved to the target position. In this way, by arranging the hall sensor 171 and the detecting magnet 172, the accuracy of the movement of the first moving bracket 143 can be significantly improved, that is, the accuracy of focusing of the camera module 100 is significantly improved, and the effect of the image shot by the camera module 100 is better.

It will be appreciated that the principle of use of the hall sensor and the detection magnet on the second moving bracket 144 is the same as the principle of use of the hall sensor 171 and the detection magnet 172 on the first moving bracket 143. And will not be described in detail here.

Referring to fig. 13, fig. 13 is a schematic diagram illustrating a part of the structure of the camera module 100 shown in fig. 4 in the first embodiment. The self-locking assembly 50 is located inside the housing 12 (see fig. 7), and the self-locking assembly 50 is disposed on the bottom plate 122. In this embodiment, a portion of the self-locking assembly 50 is disposed proximate to the first moving bracket 143. The self-locking assembly 50 is used to lock the first moving bracket 143 when energized. The energization of the self-locking assembly 50 may be determined according to whether the first moving bracket 143 is relatively moved. For example, when the first moving bracket 143 is not relatively moved, the self-locking assembly 50 is not energized. When the first moving bracket 143 moves relatively, the self-locking assembly 50 is energized. In addition, when the first moving bracket 143 is not relatively moved, the first moving bracket 143 is at the target position. The target position may be a focusing position of the first movable bracket 143, or may be a fixed position of the first movable bracket 143 when the camera module 100 is not started to take a photograph.

In the present embodiment, the self-locking assembly 50 locks the first moving bracket 143 by applying pressure to the first moving bracket 143 in the Y-axis direction. The construction and locking principle of the self-locking assembly 50 will be described in detail below with reference to the associated drawings. And will not be described in detail here.

It can be understood that when the first moving bracket 143 moves to the target position relative to the guide rail 141, the self-locking assembly 50 locks the first moving bracket 143, so that the stability of the first lens 151 on the first moving bracket 143 is better, that is, the first lens 151 on the first moving bracket 143 is not easy to move due to external shake or vibration, so that when the user is taking a picture, the taken image is not easy to deform or blur. Particularly, when the user takes a picture during the movement, the effect of the image taken by the camera module 100 is also better.

In addition, when the first moving bracket 143 moving to the target position is locked, the first moving bracket 143 can avoid collision with other components in the camera module 100, so that the collision risk of the first moving bracket 143 is reduced, and forced vibration can be avoided. It is understood that forced vibration refers to vibration that occurs under the influence of a periodic external force.

In other embodiments, a portion of the self-locking assembly 50 may also be disposed proximate to the second movable support 144. The self-locking assembly 50 can be used to lock the second moving bracket 144 when energized.

In other embodiments, the self-locking assembly 50 is two sets. One set is disposed adjacent to the first moving bracket 143 and the other set is disposed adjacent to the second moving bracket 144. At this time, the self-locking assembly 50 can be used to lock both the first moving bracket 143 and the second moving bracket 144 when energized.

Referring to fig. 14, fig. 14 is a partially exploded view of the self-locking assembly 50 of fig. 13. The self-locking assembly 50 includes a first circuit board 51, a connector 52, a self-locking member 53, and a force application member 54.

The first circuit board 51 may be a hard circuit board, a flexible circuit board, or a soft-hard combined circuit board. In addition, the first circuit board 51 includes a first pin 511 and a second pin 512 disposed at intervals.

Referring to fig. 15, fig. 15 is a schematic diagram of a portion of the image capturing module 100 shown in fig. 13. The first circuit board 51 is fixed to the bottom plate 122. The first circuit board 51 is located at the periphery of the bottom plate 122. As shown in fig. 13, a part of the first circuit board 51 is located between the substrate 13 and the second moving bracket 144, that is, the first circuit board 51 is spaced apart from the second moving bracket 144. At this time, the space between the substrate 13 and the second moving bracket 144 can be effectively utilized, thereby remarkably improving the space utilization. Further, a communication hole 134 is formed in an end portion of the substrate 13 close to the bottom plate 122. The communication hole 134 communicates a side of the substrate 13 close to the second moving bracket 144 to a side of the substrate 13 far from the second moving bracket 144. Part of the first circuit board 51 passes through the substrate 13 via the communication hole 134 and is electrically connected to the module circuit board 20. In this way, signals can be transmitted to the first circuit board 51 via the module circuit board 20.

Referring to fig. 14 again, the connector 52 includes a fixing base 521, a connecting member 522 and a conductive piece 523.

The fixing seat 521 may be made of an insulating material. For example, the fixing base 521 is made of plastic. As shown in fig. 15, the fixing base 521 is fixed to the first circuit board 51. In other embodiments, the fixing base 521 is partially fixed to the first circuit board 51 and partially fixed to the bottom plate 122.

The conductive sheet 523 is made of a conductive material. For example, the conductive sheet 523 is a steel sheet, an aluminum sheet, or a copper sheet. The conductive piece 523 is fixed to the fixing base 521 through the connecting member 522.

Referring again to fig. 14, the connecting member 522 is a conductive post. The fixing base 521 and the conductive piece 523 are respectively provided with a first through hole 524. Referring to fig. 15, the connecting member 522 sequentially passes through the fixing base 521 and the first through hole 524 on the conductive plate 523, and is fixed in the first through hole 524. In this way, the conductive piece 523 is fixed to the fixing base 521 through the connecting member 522. In other embodiments, the connector 522 may also be other fasteners, such as pins or screws.

In the present embodiment, the material of the connecting member 522 is a conductive material. When one end of the connecting member 522 passes through the through hole 524 of the fixing base 521, one end of the connecting member 522 is electrically connected to the first pin 511 of the first circuit board 51.

In other embodiments, the connector 52 may be a connector of other configurations. The connector can be electrically connected to the first pins 511 of the first circuit board 51. The specific embodiment is not limited.

Referring to fig. 16, fig. 16 is an exploded view of the self-locking member 53 shown in fig. 14. The self-locking member 53 includes a base 531, a rotating shaft 532, a rotating member 533, an elastic member 534, and a stopper 535. It is understood that the elastic member 534 may be a spring or a leaf spring. The elastic member 534 of the present embodiment is described taking a spring as an example.

The base 531 includes a fixing portion 5311 and a limiting portion 5312. The limiting portion 5312 is connected to one side of the fixing portion 5311 and located at a periphery of the fixing portion 5311. At this time, the base 531 is substantially "+". The fixing portion 5311 and the limiting portion 5312 may be integrally formed. Fig. 16 schematically distinguishes the fixing portion 5311 from the limiting portion 5312 by a broken line.

In addition, the fixing portion 5311 is provided with a second through hole 5313. The second through holes 5313 penetrate through opposite surfaces of the fixing portion 5311. The second through hole 5313 is disposed opposite to the second pin 512 (see fig. 14).

As shown in fig. 15, the base 531 is spaced from the connector 52. The partial fixing portion 5311 is fixed to the bottom plate 122, and the partial fixing portion 5311 is fixed to the first circuit board 51. In other embodiments, the fixing portion 5311 may be entirely fixed to the first circuit board 51. As shown in fig. 13, the base 531 is spaced apart from the first moving bracket 143.

Referring to fig. 15 and 16 again, one end of the rotating shaft 532 passes through the second through hole 5313 of the fixing portion 5311. The rotating shaft 532 is fixedly connected with the hole wall of the second through hole 5313. I.e., one end of the rotation shaft 532 is fixed to the base 531. In addition, the material of the rotating shaft 532 is conductive material. For example copper, aluminum, silver, gold, or an aluminum alloy, etc. The shaft 532 passing through the second through hole 5313 of the fixing portion 5311 is electrically connected to the second pin 512 (see fig. 14).

Referring again to fig. 16, the rotating member 533 includes a middle portion 5331, a first end portion 5332, and a second end portion 5333. The first end portion 5332 and the second end portion 5333 are respectively connected to two ends of the middle portion 5331. Both the first end portion 5332 and the second end portion 5333 are bent toward the same side of the middle portion 5331.

In addition, the middle portion 5331 of the rotating member 533 is provided with two protrusions 5334. The protruding direction of the two protruding portions 5334 is opposite to the bending direction of the first end portion 5332 and the second end portion 5333. In other embodiments, the number of protrusions 5334 may be one, or greater than two. In addition, a third through hole 5335 is opened in both of the two protrusions 5334. The third through-hole 5335 penetrates both surfaces of the protrusion 5334 opposite to each other.

As shown in fig. 15, the other end of the rotating shaft 532 sequentially passes through the third through holes 5335 on the two protrusions 5334 and rotates relative to the wall of the third through holes 5335. Thus, the rotating member 533 is rotatably coupled to the fixing portion 5311 via the rotation shaft 532.

In addition, the material of the rotating member 533 is a conductive material. For example copper, aluminum, silver, gold, or an aluminum alloy, etc. The rotation member 533 is electrically connected to the rotation shaft 532.

Referring to fig. 15 again, one end of the elastic member 534 is fixed to the limiting portion 5312 of the base 531, and the other end is fixed to the second end portion 5333 of the rotating member 533. At this time, the elastic member 534 is located at a side of the rotation member 533 away from the connector 52.

In addition, the stopper 535 is fixed to a side of the second end 5333 of the rotating member 533 away from the elastic member 534. At this time, the stopper 535 is disposed opposite to the elastic member 534. The stopper 414 may be made of a polymer material. For example, thermoplastic polyurethane elastomer rubber (thermoplastic polyurethanes, TPU), thermoplastic elastomer (thermoplastic elastomer, TPE), thermoplastic rubber material (thermoplastic rubber material, TPR). In other embodiments, the stopper 414 may be made of a metal material.

In the present embodiment, the stopper 535 is fixed to the second end 5333 of the rotating member 533 by an adhesive tape or glue. In other embodiments, the stopper 535 may also be integrally formed with the second end 5333 of the rotating member 533.

Referring to fig. 15 again, one end of the force application member 54 is fixed to the conductive piece 523 of the connector 52, and the other end is fixed to the first end 5332 of the rotation member 533. In the present embodiment, the hook portions are provided on the conductive piece 523 and the first end portion 5332 of the rotation member 533. At this time, both ends of the urging member 54 are fixed to the hook portions on the conductive piece 523 and the first end portion 5332, respectively. In this way, the connection between the urging member 54, the conductive piece 523, and the rotation member 533 is more stable.

The force application member 54 is a shape memory alloy (shape memory alloy, SMA). Thus, a current path is formed among the first circuit board 51, the connecting member 522, the conductive piece 523, the urging member 54, the rotation shaft 532, and the rotation member 533. It is understood that the current path refers to a loop in which current can be transmitted between the first circuit board 51, the connection member 522, the conductive piece 523, the urging member 54, the rotation shaft 532, and the rotation member 533.

It will be appreciated that the biasing member 54 is configured to apply a biasing force to the rotating member 533 when energized. The energization of the biasing member 54 may be determined according to whether the first moving bracket 143 moves relatively. For example, when the first moving bracket 143 is not relatively moved, the urging member 54 is not energized. When the first moving bracket 143 moves relatively, the force application member 54 is energized. In addition, when the first moving bracket 143 is not relatively moved, the first moving bracket 143 is at the target position.

When the urging member 54 is energized, a current signal acts on the urging member 54, and the urging member 54 contracts. At this time, the urging member 54 generates a contraction force. In this way, the biasing member 54 in the contracted state can apply a biasing force to the first end portion 5332 of the rotating member 533. The acting force is a contraction force generated when the urging member 54 is energized. The direction of the force is the negative direction of the Y axis. Thus, when the first end portion 5332 receives a tensile force greater than the elastic force of the elastic member 534, the rotating member 533 rotates relative to the rotating shaft 532, the second end portion 5333 of the rotating member 533 compresses the elastic member 534, and the rotating member 533 drives the stopper 535 to rotate relative to the rotating shaft 532.

In this embodiment, the self-locking assembly 50 has two states. One is the locked state. One is the unlocked state. These two states will be described in detail below in connection with the associated figures.

Locking state: referring to fig. 17 and 18, fig. 17 is a schematic diagram illustrating a state of the structure of the camera module 100 shown in fig. 4 in the first embodiment. Fig. 18 is an enlarged schematic view of a portion of the camera module 100 shown in fig. 17 at B. When the first moving bracket 143 moves to the target position, the module circuit board 20 does not transmit the current signal to the first circuit board 51, the urging member 54 is not energized, the urging member 54 is not contracted, and the urging member 54 does not apply the pulling force to the first end 5332 of the rotating member 533. At this time, since the elastic member 534 is in a compressed state, the first end portion 5332 of the rotating member 533 abuts against the limiting portion 5312 of the base 531 under the elastic force of the elastic member 534. In addition, the second end 5333 of the rotating member 533 drives the stopper 535 to rotate under the elastic force of the elastic member 534, so that the stopper 535 contacts the first moving bracket 143, and a static friction force can be generated between the stopper 535 and the first moving bracket 143. It will be appreciated that stop 535 applies a negative Y-axis pressure to first moving bracket 143. At this time, when the first moving bracket 143 has a moving tendency in the X-axis direction, a static friction force is generated between the stopper 535 and the first moving bracket 143. Wherein the static friction force can prevent the first moving bracket 143 from sliding in the X-axis direction. Thus, the first moving bracket 143 is locked by the self-locking assembly 50.

In one embodiment, the locking state of the self-locking assembly 50 can be applied to a scene where the camera module 100 is focused, or the camera module 100 is in a scene where no image or video is captured.

Unlocking state: referring to fig. 19 in combination with fig. 17, fig. 19 is a schematic view of the camera module 100 shown in fig. 4 in another state of the structure of the first embodiment. When the first moving bracket 143 starts moving relative to the target position, the module circuit board 20 transmits a current signal to the first circuit board 51, and a loop is formed among the first circuit board 51, the connecting member 522, the conductive piece 523, the force applying member 54, the rotating shaft 532, and the rotating member 533. The urging member 54 is energized, and the urging member 54 contracts. The force application member 54 generates a contractive force. In this way, the biasing member 54 in the contracted state can apply a tensile force to the first end portion 5332 of the rotating member 533, wherein the direction of the tensile force is the negative direction of the Y axis. When the first end portion 5332 receives a tensile force greater than the elastic force of the elastic member 534, the second end portion 5333 of the rotating member 533 compresses the elastic member 534, and the rotating member 533 rotates relative to the rotation shaft 532. Thus, the first end portion 5332 of the rotating member 533 is separated from the stopper portion 5312 of the base 531. In addition, the rotation member 533 drives the stopper 535 to rotate, so that the stopper 535 is separated from the first moving bracket 143. The first moving bracket 143 is in an unlocked state.

In one scenario, the unlocked state of the self-locking assembly 50 may be applied to a scenario where the camera module 100 is in focus.

The self-locking assembly 50 of the first embodiment of this embodiment is described above in detail. Several arrangement effects of the self-locking assembly 50 of the present embodiment will be described below in conjunction with the above respective drawings.

In the present embodiment, the direction of the urging force of the urging member 54 applied to the rotation member 533 is the same as the direction of the urging force of the stopper 535 applied to the first moving bracket 143. At this time, the urging member 54 is located on the same side of the rotation member 533 as the first moving bracket 143. The extending direction of the urging member 54 can have an overlapping region with the extending direction of the first moving bracket 143 in the Y axis. In this way, when the length of the urging member 54 is increased to a large extent, the urging member 54 does not increase the length of the lens assembly 101 in the Y-axis direction. When the length of the urging member 54 is increased to a large extent, the contraction length of the urging member 54 when energized is also large, and at this time, the angle by which the urging member 54 pulls the rotation member 533 is also large, and the distance by which the stopper 535 is separated from the first moving bracket 143 is also large. Thus, when the first moving bracket 143 moves in the X-axis direction, interference with the stopper 535 is not easily generated.

In other embodiments, the direction of the force applied by the force applying member 54 to the rotating member 533 may be different from the direction of the pressure applied by the stopper 535 to the first moving bracket 143.

In the present embodiment, the connection position of the stopper 535 and the rotating member 533 is the first position. The first position of the present embodiment is at the second end 5333 of the rotating member 533. The connection position of the urging member 54 and the rotating member 533 (i.e., the urging position of the urging member 54 against the rotating member 533) is the second position. The second position of the present embodiment is located at the first end 5332 of the rotating member 533. The rotational position of the rotational member 533 is located between the first position and the second position. At this time, the limiting block 535 and the force application member 54 are located at two sides of the rotating shaft 532, so that the limiting block 535 and the force application member 54 are not easy to interfere with each other during movement, and reliability of the self-locking assembly 50 is ensured.

In other embodiments, the first and second positions may be located on the same side of the rotating member 533. For example, the first end 5332 of the rotating member 533 is rotatably connected to the base 531 via a rotation shaft 532. The urging member 54 urges the middle portion 5331 of the rotation member 533. The stopper 535 is still fixed to the second end 5333 of the rotating member 533.

In the present embodiment, the elastic member 534 is located at a side of the rotating member 533 away from the stopper 535. At this time, the elastic member 534 is disposed away from the first moving bracket 143. At this time, when the first moving bracket 143 moves in the X-axis direction, the elastic member 534 does not easily interfere with the first moving bracket 143, thereby ensuring the reliability of the self-locking assembly 50.

In addition, the elastic member 534 is disposed opposite to the stopper 535. At this time, the elastic member 534 is disposed away from the urging member 54. At this time, when the urging member 54 applies a tensile force to the rotation member 533, the elastic member 534 does not easily interfere with the urging member 54, thereby ensuring the reliability of the self-locking assembly 50.

In other embodiments, the elastic member 534 is located at a side of the rotation member 533 near the first moving bracket 143.

In other embodiments, the elastic member 534 may be located on the same side of the rotational position of the rotational member 533 as the urging member 54.

In the present embodiment, the rotation shaft 532 can be used to rotate the rotation member 533 relative to the base 531, and can also be used as a part of the current path. The spindle 532 has a "one-thing-multiple-use" effect. In addition, the rotating member 533 can be used to rotate the stopper 535, and can also be a part of the current path. The rotating member 533 also has a "one-thing-multiple-use" effect.

In the present embodiment, the distance between the first position and the rotational position of the rotational member 533 is the first distance. The second position is a second distance from the rotational position of the rotational member 533. The first distance is greater than the second distance. At this time, when the urging member 54 is energized, the urging member 54 pulls the rotation member 533 to rotate at a large angle, and the stopper 535 is separated from the first moving bracket 143 by a large distance. Thus, when the first moving bracket 143 moves in the X-axis direction, interference with the stopper 535 is not easily generated.

The structure of the camera module 100 is specifically described above. Hereinafter, a photographing method of the camera module 100 will be described in conjunction with the above structure of the camera module 100 (refer to fig. 1 to 19).

Referring to fig. 20, fig. 20 is a flowchart illustrating a photographing method of the photographing module 100 shown in fig. 1 according to the first embodiment. The photographing method of the photographing module 100 includes:

s100 receives a photographing signal. It is understood that the photographing signal may be a signal generated by the screen 10 when the user presses the screen 10. In addition, the shooting signal may be a signal formed by the screen 10 generating a touch signal and transmitting the touch signal to the host circuit board 90 when the user presses the screen 10, and the chip on the host circuit board 90 processing the touch signal.

In this embodiment, the module circuit board 20 may be used to receive a photographing signal.

S200 controls the energizing member 54 to energize, so that the energizing member 54 applies an acting force to the rotating member 533 to drive the rotating member 533 to overcome the elastic force of the elastic member 534, and drive the stopper 535 to rotate and leave the first moving bracket 143. It will be appreciated that the present embodiment is described with respect to the use of the self-locking assembly 50 to lock the first movable bracket 143, and that in other embodiments, the self-locking assembly 50 may be used to lock the second movable bracket 144. In addition, when the number of the self-locking assemblies 50 is two, one set of the self-locking assemblies 50 is used for locking the first moving bracket 143, and the other set is used for locking the second moving bracket 144.

Specifically, the force application member 54 of the present embodiment is SMA. After the module circuit board 20 receives the shooting signal, the module circuit board 20 controls the power-on of the force application member 54. At this time, the current signal acts on the urging member 54, and the urging member 54 contracts. The force application member 54 generates a contractive force. In this way, the biasing member 54 in the contracted state can apply a tensile force to the first end portion 5332 of the rotating member 533. When the first end 5332 is pulled by a force greater than the elastic force of the elastic member 534, the rotating member 533 overcomes the elastic force of the elastic member 534, and the second end 5333 of the rotating member 533 compresses the elastic member 534, and the rotating member 533 rotates relative to the rotating shaft 532. Thus, the stopper 535 also rotates relative to the rotation shaft 532. The stopper 535 is separated from the first moving bracket 143.

S300 controls the first moving bracket 143 to drive the first lens 151 to move along the optical axis direction of the optical lens 10.

It can be understood that, since the optical axis direction of the optical lens 10 is the X-axis direction, the first moving bracket 143 can drive the first lens 151 to move along the positive X-axis direction or the negative X-axis direction. The moving distance of the first lens 151 may be set according to the focusing requirements of the user.

In this embodiment, when the module circuit board 20 transmits a current signal to the first coil 146 through the lens circuit board 16, the first coil 146 is energized, and the first magnet 145 can generate an ampere force along the negative X-axis direction under the action of the first coil 146. At this time, the first magnet 145 pushes the first moving bracket 143 to move in the X-axis negative direction under an ampere force. Thus, the first lens 151 fixed to the first moving bracket 143 can also move in the X-axis negative direction.

S400, when the first moving bracket 143 moves to the target position, the force application member 54 is controlled to be powered off, and the rotating member 533 drives the stopper 535 to rotate under the elastic force of the elastic member 534, so that the stopper 535 presses the first moving bracket 143.

Specifically, when the first moving bracket 143 moves to the target position, the module circuit board 20 controls the force application member 54 to be powered off. When the current signal does not act on the urging member 54, the urging member 54 does not contract, and the urging member 54 does not apply a tensile force to the first end portion 5332 of the rotating member 533. At this time, since the elastic member 534 is in a compressed state, the second end 5333 of the rotating member 533 drives the stopper 535 to rotate under the elastic force of the elastic member 534, so that the stopper 535 contacts the first moving bracket 143, and a static friction force is generated between the stopper 535 and the first moving bracket 143. In this way, the stopper 535 can press against the first moving bracket 143.

S500 controls the light sensing chip 30 to convert the optical signal into an electrical signal and output.

Specifically, the module circuit board 20 controls the photosensitive chip 30 to collect the ambient light passing through the optical lens 10. Converts the collected ambient light into an electrical signal and outputs the electrical signal to the host circuit board 90.

In this embodiment, the first moving bracket 143 is locked by the self-locking assembly 50, so that the stability of the first lens 151 on the first moving bracket 143 is better, that is, the first lens 151 on the first moving bracket 143 is not easy to move due to external shake or vibration, so that when a user takes a picture, the taken picture is not easy to deform or blur. Particularly, when the user takes a picture during the movement, the effect of the image taken by the camera module 100 is also better.

In one embodiment, after "controlling the first moving bracket 143 to move the first lens 151 along the optical axis direction of the optical lens 10", the method further includes:

the hall sensor 171 detects the magnetic field strength of the detection magnet 172.

When it is confirmed that the magnetic field strength is not equal to the preset magnetic field strength, the first moving bracket 143 is controlled to drive the first lens 151 to move to the target position along the optical axis direction of the optical lens 10.

It will be appreciated that when a user desires to focus the camera module 100, the lens circuit board 16 transmits a current signal to the first coil 146. The first magnet 145 pushes the first moving bracket 143 to move in the positive X-axis direction or the negative X-axis direction with respect to the rail 141 under an ampere force. At this time, the first moving bracket 143 is liable to appear not to move to the target position. In the present embodiment, the hall sensor 171 detects the magnetic field intensity of the detection magnet 172, and determines whether or not the magnetic field intensity is equal to the preset magnetic field intensity at the target position. When the magnetic field strength is not equal to the preset magnetic field strength at the target position, the hall sensor 171 feeds back to the module circuit board 20 through the lens circuit board 16. At this time, the module circuit board 20 can provide the compensation current signal to the first coil 146, thereby moving the first moving bracket 143 to the target position. In this way, the hall sensor 171 and the detecting magnet 172 can improve the focusing accuracy of the camera module 100, so that the effect of the image shot by the camera module 100 is better.

A lens assembly 101 is described in detail above. Another way of arranging the lens assembly 101 will be described in detail with reference to the accompanying drawings.

In the second embodiment, the technical content identical to that of the first embodiment will not be described in detail: referring to fig. 21, fig. 21 is a partially exploded view of another embodiment of the lens assembly 101 shown in fig. 6. The lens assembly 101 includes a housing 12, a motor 14, a lens 15, a lens circuit board 16, a hall sensor 171, a detection magnet 172, and a self-locking assembly 50. The arrangement of the housing 12, the motor 14, the lens 15, the lens circuit board 16, the hall sensor 171, and the detection magnet 172 can be referred to as the arrangement of the housing 12, the motor 14, the lens 15, the lens circuit board 16, the hall sensor 171, and the detection magnet 172 of the first embodiment. And will not be described in detail here.

Referring to fig. 22, fig. 22 is a schematic diagram illustrating a part of the structure of the camera module 100 shown in fig. 4 in the second embodiment. The self-locking assembly 50 is disposed proximate to the first movable bracket 143, and a portion of the self-locking assembly 50 is located between the first movable bracket 143 and the base plate 122. The self-locking assembly 50 is used to lock the first moving bracket 143 when energized. In the present embodiment, the self-locking assembly 50 locks the first moving bracket 143 by applying pressure to the first moving bracket 143 in the Z-axis direction. Compared to the self-locking assembly 50 of the first embodiment, which presses the first movable bracket 143 along the Y-axis direction, the self-locking assembly 50 of the present embodiment can effectively utilize the space between the first movable bracket 143 and the bottom plate 122, thereby improving the space utilization of the lens assembly 101.

Referring to fig. 23, fig. 23 is a partially exploded view of the self-locking assembly 50 of fig. 22. The self-locking assembly 50 includes a first circuit board 51, a self-locking member 53, and a force application member 54.

The arrangement of the first circuit board 51 may refer to the arrangement of the first circuit board 51 of the first embodiment. And will not be described in detail here. Unlike the first circuit board 51 of the first embodiment, the first circuit board 51 of the present embodiment is short in size in the Y-axis direction. The first pin 511 and the second pin 512 of the first circuit board 51 may be disposed close to each other. Of course, in other embodiments, the first pin 511 and the second pin 512 may be separately disposed.

Referring to fig. 24, fig. 24 is an exploded view of the self-locking member 53 shown in fig. 23. The self-locking member 53 includes a base 531, a rotating shaft 532, a rotating member 533, an elastic member 534, and a stopper 535.

The base 531 includes a first fixing portion 5311, a connecting portion 5312, and a second fixing portion 5313. The connection portion 5312 is located at one side of the first fixing portion 5311 and is connected to a periphery of the first fixing portion 5311. The second fixing portion 5313 is connected to a side of the connecting portion 5312 away from the first fixing portion 5311. The second fixing portion 5313 is disposed opposite to the first fixing portion 5311. At this time, the partial connection portion 5312 is connected between the first fixing portion 5311 and the second fixing portion 5313. In the present embodiment, the first fixing portion 5311, the connecting portion 5312, and the second fixing portion 5313 are integrally formed. Fig. 24 schematically distinguishes the first fixing portion 5311, the connecting portion 5312, and the second fixing portion 5313 by broken lines.

As shown in fig. 22, the first fixing portion 5311 is fixed to the bottom plate 122. At this time, the base 531 is fixed to the bottom plate 122. The base 531 is spaced apart from the first moving bracket 143. In other embodiments, a portion of the first fixing portion 5311 is fixed to the first circuit board 51, and a portion of the first fixing portion 5311 is fixed to the bottom plate 122.

Referring to fig. 24 again, the connection portion 5312 is provided with a first through hole 5314. The first through hole 5314 penetrates opposite surfaces of the connection portion 5312.

In addition, the shaft 532 includes a main shaft 5321 and a collar 5322. Collar 5322 has a radius greater than the radius of main shaft 5321. As shown in fig. 23, one end of the main shaft 5321 passes through the first through hole 5314 of the connection portion 5312. The main shaft 5321 is fixedly connected with the hole wall of the first through hole 5314. In addition, the collar 5322 is sleeved on the main shaft 5321. Collar 5322 is rotatably coupled to spindle 5321.

Referring again to fig. 24, the rotating member 533 includes a middle portion 5331, a first end portion 5332, and a second end portion 5333. The first end portion 5332 and the second end portion 5333 are respectively connected to two ends of the middle portion 5331. In the present embodiment, the middle portion 5331 of the rotating member 533 is arc-shaped. The shape of the middle portion 5331 of the swivel 533 is adapted to the shape of the outer surface of the collar 5322. In other embodiments, the middle portion 5331 of the rotating member 533 may have other shapes.

As shown in fig. 23, a middle portion 5331 of the rotating member 533 is fixed to the collar 5322. At this time, the middle portion 5331 of the rotating member 533 may rotate as the collar 5322 rotates relative to the main shaft 5321. At this time, the rotating member 533 is rotatably coupled to the base 531 via the rotation shaft 532. In addition, the first end 5332 and the second end 5333 of the rotating member 533 are located on both sides of the collar 5322. The first end portion 5332 of the rotating member 533 is located on a side of the second fixing portion 5313 away from the first fixing portion 5311.

The rotating member 533 is made of a magnetic material. For example, the rotating member 533 is a magnet or a magnetic steel.

Referring to fig. 23 and 24 again, one end of the elastic member 534 is fixed to the first fixing portion 5311 of the base 531, and the other end is fixed to the second end portion 5333 of the rotating member 533. It is understood that the elastic member 534 may be a spring or a leaf spring. The elastic member 534 of the present embodiment is exemplified by a spring.

In addition, the stopper 535 is fixed to a side of the first end 5332 of the rotating member 533 away from the second fixing portion 5313. The stopper 535 is located between the rotating member 533 and the first moving bracket 143 (see fig. 22). The material of the stopper 535 may refer to the material of the stopper 535 in the first embodiment. And will not be described in detail here.

Referring to fig. 25 in combination with fig. 23, fig. 25 is a partially exploded view of the self-locking assembly 50 of fig. 22. The force application member 54 includes a magnetic member 541 and a coil 542 wound around the surface of the magnetic member 541. In addition, the first fixing portion 5311 and the second fixing portion 5313 of the base 531 are respectively provided with a second through hole 5315.

One end of the magnetic element 541 passes through the second through hole 5315 of the first fixing portion 5311 and is fixedly connected to the hole wall of the second through hole 5315. The other end of the magnetic member 541 passes through the second through hole 5315 of the second fixing portion 5313 and faces the first end portion 5332 of the rotating member 533. In this way, the connection stability between the magnetic member 541 and the base 531 is better.

In addition, the coil 542 is located between the first fixing portion 5311 and the second fixing portion 5313. The input terminal of the coil 542 is electrically connected to the first pin 511 of the first circuit board 51. The output end of the coil 542 is electrically connected to the second pin 512 of the first circuit board 51. At this time, the first circuit board 51 forms a current path with the coil 542.

It will be appreciated that the biasing member 54 is configured to apply a biasing force to the rotating member 533 when the coil 542 is energized. The energization of the coil 542 may be determined according to whether the first moving bracket 143 moves relatively. For example, when the first moving bracket 143 is not relatively moved, the coil 542 is not energized. When the first moving bracket 143 moves relatively, the coil 542 is energized. In addition, when the first moving bracket 143 is not relatively moved, the first moving bracket 143 is at the target position.

Specifically, when the coil 542 is energized, a current signal acts on the coil 542, and the coil 542 generates a magnetic field. At this time, since the material of the rotating member 533 is a magnetic material, a magnetic attraction force is generated between the urging member 54 and the first end portion 5332 of the rotating member 533. The urging member 54 is for urging the rotating member 533 when energized. The acting force is a magnetic attraction force between the urging member 54 and the rotating member 533. When the magnetic attraction between the urging member 54 and the first end portion 5332 of the rotating member 533 is greater than the elastic force of the elastic member 534, the second end portion 5333 of the rotating member 533 stretches the elastic member 534, and the middle portion 5331 of the rotating member 533 rotates as the collar 5322 rotates relative to the main shaft 5321. Thus, the stopper 535 fixed to the first end 5332 of the rotating member 533 also rotates with the collar 5322 relative to the main shaft 5321.

Locking state: referring to fig. 26 and 27, fig. 26 is a schematic diagram illustrating a state of the structure of the camera module 100 shown in fig. 4 in the second embodiment. Fig. 27 is an enlarged schematic view of a portion of the camera module 100 shown in fig. 26 at C. When the first moving bracket 143 moves to the target position, the module circuit board 20 does not transmit a current signal to the first circuit board 51, and the coil 542 is not energized. In addition, since the elastic member 534 is in a stretched state, the elastic member 534 applies an elastic force in the negative Z-axis direction to the second end portion 5333 of the rotating member 533. At this time, the stopper 535 contacts the first moving bracket 143 under the elastic force of the elastic member 534, and generates a static friction force with the first moving bracket 143. It will be appreciated that the stopper 535 applies pressure to the first moving bracket 143 in the positive Z-axis direction. At this time, when the first moving bracket 143 has a moving tendency in the X-axis direction, a static friction force is generated between the stopper 535 and the first moving bracket 143. Wherein the static friction force can prevent the first moving bracket 143 from sliding in the X-axis direction. Thus, the first moving bracket 143 is locked by the self-locking assembly 50.

Unlocking state: referring to fig. 28 in combination with fig. 26, fig. 28 is a schematic diagram illustrating another state of the structure of the camera module 100 shown in fig. 4 in the second embodiment. When the first moving bracket 143 starts moving relative to the target position, the module circuit board 20 transmits a current signal to the first circuit board 51, the coil 542 is energized, and the coil 542 generates a magnetic field. At this time, since the material of the rotating member 533 is a magnetic material, a magnetic attraction force is generated between the urging member 54 and the first end portion 5332 of the rotating member 533. At this time, the first end 5332 of the rotating member 533 receives a pulling force in the negative Z-axis direction. In addition, since the elastic member 534 is in a stretched state, the elastic member 534 applies a pulling force in the negative Z-axis direction to the second end portion 5333 of the rotating member 533. At this time, the first end 5332 of the rotating member 533 receives an elastic force in the positive Z-axis direction. It will be appreciated that when the magnetic attraction between the urging member 54 and the first end portion 5332 of the rotating member 533 is greater than the elastic force of the elastic member 534, the second end portion 5333 of the rotating member 533 stretches the elastic member 534, and the middle portion 5331 of the rotating member 533 rotates as the collar 5322 rotates relative to the main shaft 5321. At this time, the first end 5332 of the rotating member 533 rotates to be in contact with the magnetic member 541. The rotation member 533 rotates the stopper 535 to separate the stopper 535 from the first moving bracket 143. The first moving bracket 143 is in an unlocked state.

The self-locking assembly 50 of the second embodiment of this embodiment is described above in detail. Several arrangement effects of the self-locking assembly 50 of the present embodiment will be described below in conjunction with the above respective drawings.

In the present embodiment, the direction of the urging force of the urging member 54 applied to the rotation member 533 is opposite to the direction of the urging force of the stopper 535 applied to the first moving bracket 143. At this time, the urging member 54 and the first moving bracket 143 are located on different sides of the rotating member 533. When the first moving bracket 143 moves in the X-axis direction, the first moving bracket 143 is not likely to interfere with the urging member 54. In addition, the magnetic field generated by the urging member 54 does not easily affect the movement of the first moving bracket 143 in the X-axis direction.

In other embodiments, the direction of the force applied to the rotating member 533 by the force applying member 54 is the same as the direction of the pressure applied to the first moving bracket 143 by the stopper 535.

In the present embodiment, the connection position of the stopper 535 and the rotating member 533 is the first position. The first position of the present embodiment is at the first end 5332 of the rotating member 533. The connection position of the urging member 54 and the rotating member 533 (i.e., the urging position of the urging member 54 against the rotating member 533) is the second position. The second position of the present embodiment is also located at the first end 5332 of the rotating member 533. The first position and the second position are both located on the same side of the rotational position of the rotational member 533. At this time, the self-locking assembly 50 is compact in structure. The urging member 54 urges the stopper 535 a short distance.

In other embodiments, the first and second positions may also be located on different sides of the rotating member 533. For example, the first position is at the first end 5332 of the rotating member 533. The second position is at the second end 5333 of the swivel 533.

In this embodiment, the elastic member 534 and the urging member 54 are located on the same side of the rotating member 533. At this time, when the first moving bracket 143 is moving, the elastic member 534 does not easily collide or interfere with the first moving bracket 143.

In addition, the elastic member 534 and the urging member 54 are located on both sides of the rotational position of the rotational member 533. At this time, when the urging member 54 urges the rotation member 533, the elastic member 534 does not easily interfere with the urging member 54.

In other embodiments, the elastic member 534 is located at a side of the rotating member 533 near the first moving bracket 143.

In other embodiments, the elastic member 534 may be located on the same side of the rotational position of the rotating member 533 as the urging member 54.

The structure of the camera module 100 is specifically described above. Hereinafter, a photographing method of the camera module 100 will be described in conjunction with the above structure of the camera module 100 (refer to fig. 21 to 28).

The photographing method of the photographing module 100 includes;

a photographing signal is received. It is understood that the photographing signal may be a signal generated by the screen 10 when the user presses the screen 10. In addition, the shooting signal may be a signal formed by the screen 10 generating a touch signal and transmitting the touch signal to the host circuit board 90 when the user presses the screen 10, and the chip on the host circuit board 90 processing the touch signal.

The force application member 54 is controlled to be energized, so that the force application member 54 applies force to the rotating member 533 to drive the rotating member 533 to overcome the elastic force of the elastic member 534, drive the stopper 535 to rotate and leave the first moving bracket 143. It will be appreciated that the present embodiment is described with respect to the use of the self-locking assembly 50 to lock the first movable bracket 143, and that in other embodiments, the self-locking assembly 50 may be used to lock the second movable bracket 144. In addition, when the number of the self-locking assemblies 50 is two, one set of the self-locking assemblies 50 is used for locking the first moving bracket 143, and the other set is used for locking the second moving bracket 144.

Specifically, the force application member 54 includes a magnetic member 541 and a coil 542 wound around the surface of the magnetic member 541. After the module circuit board 20 receives the photographing signal, the module circuit board 20 controls the coil 542 to be energized. At this time, the coil 542 generates a magnetic field. Since the rotating member 533 is made of a magnetic material, a magnetic attraction force is generated between the urging member 54 and the first end portion 5332 of the rotating member 533. At this time, the first end 5332 of the rotating member 533 receives a pulling force in the negative Z-axis direction. In addition, since the elastic member 534 is in a stretched state, the elastic member 534 applies a pulling force in the negative Z-axis direction to the second end portion 5333 of the rotating member 533. At this time, the first end 5332 of the rotating member 533 receives an elastic force in the positive Z-axis direction. It can be appreciated that when the magnetic attraction force between the urging member 54 and the first end portion 5332 of the rotating member 533 is greater than the elastic force of the elastic member 534, the rotating member 533 overcomes the elastic force of the elastic member 534, the second end portion 5333 of the rotating member 533 stretches the elastic member 534, and the middle portion 5331 of the rotating member 533 rotates as the collar 5322 rotates relative to the main shaft 5321. At this time, the first end 5332 of the rotating member 533 rotates to be in contact with the magnetic member 541. Thus, the rotation member 533 rotates the stopper 535 to separate the stopper 535 from the first moving bracket 143.

The first moving bracket 143 is controlled to drive the first lens 151 to move along the optical axis direction of the optical lens 10.

When the first moving bracket 143 moves to the target position, the force application member 54 is controlled to be powered off, and the rotating member 533 drives the stop block 535 to rotate under the elastic force of the elastic member 534, so that the stop block 535 presses the first moving bracket 143.

Specifically, when the first moving bracket 143 moves to the target position, the module circuit board 20 controls the coil 542 to be deenergized. At this time, the coil 542 is not energized. The coil 542 does not generate a magnetic field. Further, since the elastic member 534 is in a stretched state, the elastic member 534 applies an elastic force in the negative Z-axis direction to the second end portion 5333 of the rotating member 533. At this time, the stopper 535 contacts the first moving bracket 143 under the elastic force of the elastic member 534, and generates a static friction force with the first moving bracket 143. In this way, the stopper 535 can press against the first moving bracket 143.

The control photosensitive chip 30 converts the optical signal into an electrical signal and outputs it.

In other embodiments, a self-locking assembly 50 may also be provided at the second moving bracket 144. At this time, the self-locking assembly 50 can also perform the above-described steps with respect to the second moving bracket 144. The details are not described here.

When it is confirmed that the magnetic field strength is not equal to the preset magnetic field strength, the first moving bracket 143 is controlled to drive the first lens 151 to move to the target position along the optical axis direction of the optical lens.

It can be appreciated that the accuracy of focusing of the camera module 100 can be improved through the hall sensor 171 and the detecting magnet 172, so that the effect of the image shot by the camera module 100 is better.

Two arrangements of the lens assembly 101 are specifically described above. The following will specifically describe another arrangement of the lens assembly 101 in connection with the accompanying drawings.

In the third embodiment, the technical content identical to that of the first embodiment and the second embodiment will not be repeated: referring to fig. 29, fig. 29 is a partially exploded view of still another embodiment of the lens assembly 101 shown in fig. 6. The lens assembly 101 includes a housing 12, a motor 14, a lens 15, a lens circuit board 16, a hall sensor 171, a detection magnet 172, and a self-locking assembly 50. The arrangement of the housing 12, the motor 14, the lens 15, the lens circuit board 16, the hall sensor 171, and the detection magnet 172 can be referred to as the arrangement of the housing 12, the motor 14, the lens 15, the lens circuit board 16, the hall sensor 171, and the detection magnet 172 of the first embodiment. And will not be described in detail here.

Referring to fig. 30, fig. 30 is a schematic diagram illustrating a state of the structure of the camera module 100 shown in fig. 4 in the third embodiment. The self-locking assembly 50 is disposed adjacent to the second moving bracket 144. The self-locking assembly 50 is used to lock the second moving bracket 144 when energized. The energization of the self-locking assembly 50 may be determined based on whether the second moving bracket 144 is relatively moving. For example, when the second moving bracket 144 is not relatively moving, the self-locking assembly 50 is not energized. When the second moving bracket 144 moves relative to each other, the self-locking assembly 50 is energized. In addition, when the second moving bracket 144 is not relatively moved, the second moving bracket 144 is in a fixed position. The fixed position is a position of the second moving bracket 144 when the camera module 100 is not activated for shooting.

In this embodiment, the self-locking assembly 50 is used to lock the fourth portion 1442 of the second moving bracket 144 when energized. It will be appreciated that the self-locking assembly 50 of the present embodiment locks the second movable bracket 144 in a fixed position as compared to the self-locking assemblies 50 of the first and second embodiments. The position can be flexibly set according to the requirement.

In other embodiments, the self-locking assembly 50 may also be used to lock the third portion 1441 of the second moving bracket 144 when energized.

In other embodiments, a portion of the self-locking assembly 50 may also be disposed proximate the first moving bracket 143. The self-locking assembly 50 may be used to lock the first moving bracket 143 when energized.

Referring to fig. 31, fig. 31 is a partially exploded view of the self-locking assembly 50 shown in fig. 30. The self-locking assembly 50 includes a first circuit board 51, a first latch 52 and a second latch 53.

The arrangement of the first circuit board 51 may refer to the arrangement of the first circuit board 51 of the second embodiment. And will not be described in detail here. The first circuit board 51 includes a first pin 511 and a second pin 512.

The first fastening member 52 has a plate-like structure. The first fastening member 52 is provided with a first through hole 521. The first through hole 521 penetrates two opposite surfaces of the first fastening piece 52. As shown in fig. 30, a part of the first fastening members 52 is fixed to the fourth portion 1442 of the second moving bracket 144, and a part of the first fastening members 52 extends in the direction of the substrate 13. In the present embodiment, the first fastening member 52 may be fixed to the fourth portion 1442 of the second moving bracket 144 by glue or tape. In other embodiments, the first latch 52 may be integrally formed with the fourth portion 1442 of the second movable bracket 144.

Referring to fig. 32, fig. 32 is a partially exploded view of the second fastening device 53 shown in fig. 30. The second locking device 53 includes a base 531, a force applying member 532, an elastic member 533, a sliding block 534, and a stopper 535. It is understood that the elastic member 533 may be a spring or a leaf spring. The elastic member 533 of the present embodiment is exemplified by a spring.

The base 531 includes a fixing portion 5311, a connecting portion 5312, a first limiting portion 5313, and a second limiting portion 5314. The connection portion 5312 is located at one side of the fixing portion 5311 and is connected to a periphery of the fixing portion 5311. The first limiting portion 5313 and the second limiting portion 5314 are connected to the connecting portion 5312. The first limiting portion 5313 and the second limiting portion 5314 are located on the same side of the connecting portion 5312 as the fixing portion 5311. The first limiting portion 5313 is disposed opposite to the second limiting portion 5314. In the present embodiment, the fixing portion 5311, the connecting portion 5312, the first limiting portion 5313, and the second limiting portion 5314 are integrally formed. Fig. 32 schematically distinguishes the fixing portion 5311, the connecting portion 5312, the first stopper portion 5313, and the second stopper portion 5314 by broken lines. In other embodiments, the fixing portion 5311, the connecting portion 5312, the first limiting portion 5313, and the second limiting portion 5314 may be bonded by an adhesive tape or glue.

As shown in fig. 30, the connection portion 5312 is fixed to the bottom plate 122. At this time, the base 531 is fixed to the bottom plate 122. In other embodiments, a portion of the connection portion 5312 is fixed to the first circuit board 51, and a portion of the connection portion 5312 is fixed to the bottom plate 122.

Referring to fig. 32 again, the fixing portion 5311 is provided with a second through hole 5315. The second through holes 5315 penetrate through opposite surfaces of the fixing portion 5311.

The manner of disposing the urging member 532 can be referred to as the manner of disposing the urging member 54 of the second embodiment. The force applying member 532 includes a magnetic member 5321 and a coil 5322 wound around the surface of the magnetic member 5321.

Referring to fig. 33, fig. 33 is a schematic view of a portion of the second fastening member 53 shown in fig. 31. One end of the magnetic member 5321 passes through the second through hole 5315 (see fig. 32) of the fixing portion 5311 and is fixedly connected to a wall of the second through hole 5315. The coil 5322 is located at one side of the fixing portion 5311 near the first limiting portion 5313 and the second limiting portion 5314. As shown in fig. 31, the input end of the coil 5322 is electrically connected to the first pin 511 of the first circuit board 51. The output end of the coil 5322 is electrically connected to the second pin 512 of the first circuit board 51. At this time, the first circuit board 51 forms a current path with the coil 5322.

Referring to fig. 34, and referring to fig. 33, fig. 34 is a schematic view of a portion of the second fastening member 53 shown in fig. 31. The elastic member 533 encloses the force member 532, i.e., the force member 532 is located inside the elastic member 533. At this time, the urging member 532 can effectively use the inner space of the elastic member 533, and the space utilization of the self-locking assembly 50 can be improved. In addition, one end of the elastic member 533 is fixed to the fixing portion 5311 of the base 531. At this time, the elastic member 533 is located at a side of the first locking member 52 away from the second moving bracket 144 (see fig. 30). In other embodiments, the elastic member 533 does not fit over the force member 532, and the elastic member 533 is spaced apart from the force member 532.

In addition, the slider 534 is fixed to an end of the elastic member 533 away from the fixing portion 5311. At this time, one end of the magnetic member 5321 faces the slider 534. In addition, the sliding block 534 is slidably connected between the first limiting portion 5313 and the second limiting portion 5314. The slider 534 is made of a magnetic material. For example, the slider 534 is a magnet or a magnetic steel.

In addition, the stopper 535 is connected to a side of the sliding block 534 away from the elastic member 533. At this time, the stopper 535 is located between the elastic member 533 and the first moving bracket 143 (see fig. 30). The material of the stopper 535 may be different from or the same as the material of the slider 534. For example, when the material of the stopper 535 is different from the material of the sliding block 534, the material of the stopper 535 may refer to the material of the stopper 535 in the first embodiment.

In the present embodiment, the stopper 535 is fixed to a side of the sliding block 534 away from the elastic member 533 by glue or tape. In other embodiments, the sliding block 534 and the stopper 535 may be integrally formed.

It will be appreciated that the stop 535 is used to lock the second moving bracket 144 when the coil 5322 is energized. The energization of the coil 5322 may be determined according to whether the second moving bracket 144 moves relatively. For example, when the second moving bracket 144 is not relatively moving, the coil 5322 is not energized. When the second moving bracket 144 moves relatively, the coil 5322 is energized. In addition, when the second moving bracket 144 is not relatively moved, the second moving bracket 144 is at the target position.

Locking state: referring to fig. 35, fig. 35 is an enlarged schematic view of a portion of the camera module 100 shown in fig. 30 at D. When the second moving bracket 144 moves to the fixed position, the module circuit board 20 does not transmit an electrical signal to the first circuit board 51. At this time, the coil 5322 is not energized (see fig. 33). Coil 5322 does not generate a magnetic field. In addition, since the elastic member 533 is in a compressed state, the elastic member 533 applies an elastic force in the Y-axis negative direction to the slider 534. At this time, the slider 534 is pressed between the elastic member 533 and the top of the first stopper 5313 and the top of the second stopper 5314. Thus, the stopper 535 is positioned in the first through hole 521 of the first fastener 52 by the supporting force of the sliding block 534. Since the hole wall of the first through hole 521 can limit the movement of the stopper 535, the second moving bracket 144 is in a locked state.

It can be appreciated that by pressing the stopper 535 in the first through hole 521 of the first fastening member 52, the stability of the stopper 535 is better, i.e. the stopper 535 is not easily moved out of the first through hole 521 of the first fastening member 52.

In one embodiment, the locked state of the self-locking assembly 50 may be applied in a scenario where the camera module 100 is in an unused state.

In other embodiments, the elastic member 533 may be in a natural state. At this time, the partial stopper 535 may also be located in the first through hole 521 of the first fastening component 52.

Unlocking state: referring to fig. 36, fig. 36 is a schematic view of another state of the structure of the camera module 100 shown in fig. 4 in the third embodiment. When the second moving bracket 144 needs to move from the fixed position along the X-axis direction, the module circuit board 20 transmits an electrical signal to the first circuit board 51, the coil 5322 (see fig. 33) is energized, and the coil 5322 generates a magnetic field. At this time, since the material of the slider 534 is a magnetic material, a magnetic attraction force is generated between the urging member 532 and the slider 534. At this time, the slider 534 receives a force applied by the urging member 532, which is a magnetic attraction force between the urging member 532 and the slider 534. In addition, since the elastic member 533 is in a compressed state, the elastic member 533 applies an elastic force in the Y-axis negative direction to the slider 534. When the magnetic attraction force of the sliding block 534 is greater than the elastic force of the sliding block 534 in the negative Y-axis direction, the sliding block 534 slides in the positive Y-axis direction relative to the first and second limiting

portions

5313 and 5314 under the action of the tensile force. At this time, the stopper 535 moves out of the first through hole 521 of the first fastening member 52 against the elastic force of the elastic member 533 under the tensile force of the sliding block 534. The second moving bracket 144 is in an unlocked state.

In one scenario, the unlocked state of the self-locking assembly 50 may be used in a scenario where the camera module 100 is in use.

In other embodiments, the second locking member 53 of the present embodiment may be configured by the connector 52, the self-locking member 53, and the urging member 54 of the first embodiment.

In other embodiments, the second locking member 53 of the present embodiment may be configured by the self-locking member 53 and the urging member 54 of the second embodiment.

In other embodiments, the structure of the connector 52, the self-locking member 53, and the urging member 54 according to the first embodiment may be the structure of the second locking member 53 according to the present embodiment.

In other embodiments, the structure of the self-locking member 53 and the biasing member 54 of the second embodiment may be the structure of the second locking member 53 of the present embodiment.

The structure of the camera module 100 is specifically described above. Hereinafter, another photographing method of the photographing module 100 will be described in conjunction with the above structure of the photographing module 100 (refer to fig. 1 to 12 and fig. 29 to 36).

Referring to fig. 37, fig. 37 is a flowchart illustrating a shooting method of the camera module 100 shown in fig. 1 according to a third embodiment. The photographing method of the photographing module 100 includes:

S200 controls the energizing member 532 to apply a force to the stopper 535 by the energizing member 532, so as to drive the stopper 535 to move out of the first through hole 521 against the elastic force of the elastic member 533.

In the present embodiment, the force applying member 532 includes a magnetic member 5321 and a coil 5322 wound around the surface of the magnetic member 5321. After the module circuit board 20 receives the photographing signal, the module circuit board 20 controls the coil 5322 to be energized. Coil 5322 generates a magnetic field. In addition, since the slider 534 is made of a magnetic material, a magnetic attraction force is generated between the urging member 532 and the slider 534. At this time, the slider 534 receives a pulling force in the positive Y-axis direction. In addition, since the elastic member 533 is in a compressed state, the elastic member 533 applies an elastic force in the Y-axis negative direction to the slider 534. When the tensile force of the sliding block 534 in the positive direction of the Y axis is greater than the elastic force of the sliding block 534 in the negative direction of the Y axis, the sliding block 534 slides in the positive direction of the Y axis relative to the first limiting portion 5313 and the second limiting portion 5314 under the action of the tensile force. The stopper 535 moves out of the first through hole 521 of the first fastening member 52 against the elastic force of the elastic member 533 under the tensile force of the sliding block 534.

S300 controls the second moving bracket 144 to drive the first lens 151 to move from the fixed position to the target position along the optical axis direction of the optical lens 10.

Specifically, the module circuit board 20 transmits a current signal to the second coil 148 through the lens circuit board 16. The second coil 148 is energized and the second magnet 147 may generate an ampere force in the negative X-axis direction. At this time, the second magnet 147 pushes the second moving bracket 144 to move in the X-axis negative direction under an ampere force. Thus, the first lens 151 fixed to the second moving bracket 144 can also move in the X-axis negative direction.

It is understood that the fixed position refers to a position of the second movable bracket 144 within the range of movement travel. The position can be flexibly set according to the requirement. The target position refers to an arbitrary position of the second moving bracket 144 within the moving stroke range.

S400 controls the light sensing chip 30 to convert the optical signal into an electrical signal and output.

S500 controls the second moving support 144 to drive the first lens 151 to move from the target position to the fixed position along the optical axis direction of the optical lens 10.

Specifically, the module circuit board 20 transmits a current signal to the second coil 148 through the lens circuit board 16. The second coil 148 is energized and the second magnet 147 can generate an ampere force in the positive X-axis direction. At this time, the second magnet 147 pushes the second moving bracket 144 to move in the positive X-axis direction under an ampere force. Thus, the first lens 151 fixed to the second moving bracket 144 can also move in the positive X-axis direction.

It will be appreciated that by changing the direction of the current signal on the second coil 148, or by locating the S-pole or N-pole of the second magnet 147, the second magnet 147 can generate an ampere force in the positive X-axis direction when the second coil 148 is energized. At this time, the second magnet 147 can push the second moving bracket 144 to move in the positive X-axis direction under an ampere force.

S600 controls the force application member 532 to be de-energized, and the partial stopper 535 stretches into the first through hole 521 under the elastic force of the elastic member 533.

Specifically, after the first moving bracket 143 moves to the fixed position, the module circuit board 20 controls the coil 5322 to be powered off. At this time, the coil 5322 is not energized. Coil 5322 does not generate a magnetic field. Since the elastic member 533 is in a compressed state, the elastic member 533 applies an elastic force in the Y-axis negative direction to the slide block 534. At this time, the slider 534 is pressed between the elastic member 533 and the top of the first stopper 5313 and the top of the second stopper 5314. Thus, the stopper 535 extends into the first through hole 521 of the first fastener 52 under the supporting force of the sliding block 534. Thus, the wall of the first through hole 521 can restrict the stopper 535 from moving.

In one embodiment, in the "control the second moving support 144 to drive the first lens 151 to move from the fixed position to the target position along the optical axis direction of the optical lens 10", the method further includes:

It can be appreciated that the accuracy of the shooting of the camera module 100 can be improved through the hall sensor 171 and the detecting magnet 172, so that the effect of the image shot by the camera module 100 is better.

The following will specifically describe another arrangement of the lens assembly 101 in connection with the accompanying drawings.

The fourth embodiment, the technical content of which is the same as that of the first to third embodiments, is not repeated: referring to fig. 38, fig. 38 is a partially exploded view of still another embodiment of the lens assembly 101 shown in fig. 6. The lens assembly 101 includes a housing 12, a motor 14, a lens 15, a lens circuit board 16, a hall sensor 171, a detection magnet 172, and a self-locking assembly 50. The arrangement of the housing 12, the motor 14, the lens 15, the lens circuit board 16, the hall sensor 171, and the detection magnet 172 can be referred to as the arrangement of the housing 12, the motor 14, the lens 15, the lens circuit board 16, the hall sensor 171, and the detection magnet 172 of the first embodiment. And will not be described in detail here.

Referring to fig. 39, fig. 39 is a schematic diagram showing a state of the structure of the image capturing module 100 shown in fig. 4 in the fourth embodiment. The self-locking assembly 50 is disposed adjacent to the first moving bracket 143. The self-locking assembly 50 is used to lock the first moving bracket 143 when energized. The energization of the self-locking assembly 50 may be determined according to whether the first moving bracket 143 is relatively moved. For example, when the first moving bracket 143 is not relatively moved, the self-locking assembly 50 is not energized. When the first moving bracket 143 moves relatively, the self-locking assembly 50 is energized. In addition, when the first moving bracket 143 is not relatively moved, the first moving bracket 143 is in a fixed position. The fixed position is a position of the first movable bracket 143 when the camera module 100 is not started to take a photograph.

The self-locking assembly 50 is used for locking the first moving bracket 143 when the first moving bracket 143 moves to a fixed position relative to the guide rail 141. It will be appreciated that, as with the third embodiment, the self-locking assembly 50 of the present embodiment locks the first movable bracket 143 in a fixed position. The fixed position refers to a position of the first moving bracket 143 within the moving stroke range. The position can be flexibly set according to the requirement.

In other embodiments, a portion of the self-locking assembly 50 may also be disposed proximate to the second movable support 144. The self-locking assembly 50 may be used to lock the second moving bracket 144 when the second moving bracket 144 is moved to the fixed position.

In other embodiments, the self-locking assembly 50 is two sets. A set of moving brackets 143 is provided adjacent to the first moving brackets 143 for locking the first moving brackets 143 when the first moving brackets 143 move to a fixed position relative to the rail 141. The other set is disposed adjacent to the second moving bracket 144 for locking the second moving bracket 144 when the second moving bracket 144 is moved to the fixed position.

Referring to fig. 40, fig. 40 is a partially exploded view of the self-locking assembly 50 of fig. 39. The self-locking assembly 50 includes a first circuit board 51, a first latch 52 and a second latch 53.

The arrangement of the first circuit board 51 may refer to the arrangement of the first circuit board 51 of the first embodiment. And will not be described in detail here. The first circuit board 51 includes a first pin 511 and a second pin 512.

The first fastening member 52 has a plate-like structure. The first fastening member 52 is provided with a first through hole 521. The first through hole 521 penetrates two opposite surfaces of the first fastening piece 52. As shown in fig. 39, a part of the first fastening members 52 are fixed to the first movable bracket 143.

Referring to fig. 41, fig. 41 is a partially exploded view of the second fastening member 53 shown in fig. 40. The second locking member 53 includes an elastic member 531, a force applying member 532, and a stopper 533. The elastic member 531 of the present embodiment is described by taking a spring plate as an example.

The elastic member 531 includes a first fixing portion 5311, a connecting portion 5312, and a second fixing portion 5313. The connection portion 5312 is connected between the first fixing portion 5311 and the second fixing portion 5313. The second fixing portion 5313 is disposed opposite to the first fixing portion 5311. At this time, the elastic member 531 is substantially "C" shaped. In this embodiment, the connection portion 5312 is arcuate. The elasticity of the elastic member 531 is better. In other embodiments, the connection 5312 may also be bar-shaped or otherwise shaped.

In this embodiment, the connecting portion 5312 and the second fixing portion 5313 are made of conductive materials.

Referring to fig. 41 again, the first fixing portion 5311 includes a first conductive segment 5314, an insulating segment 5315 and a second conductive segment 5316. One end of the insulating section 5315 is connected to the first conductive section 5314 and the other end is connected to the second conductive section 5316. The second conductive segment 5316 is connected to the connection portion 5312. In this embodiment, the insulating segment 5315 is located on the same side of the first conductive segment 5314 as the second conductive segment 5316. In other embodiments, the insulating segment 5315 may also be located between the first and second

conductive segments

5314, 5316.

Referring to fig. 42, fig. 42 is a schematic view of a portion of the self-locking assembly 50 shown in fig. 39. The first fixing portion 5311 of the elastic member 531 is fixed to the first circuit board 51. The elastic member 531 is located at a side of the first locking member 52 (see fig. 39) away from the first moving bracket 143 (see fig. 39).

In addition, the stopper 533 is fixed to a side of the second fixing portion 5313 away from the first fixing portion 5311. At this time, the stopper 533 is located between the first moving bracket 143 and the second fixing portion 5313 of the elastic member 531. The material of the stopper 533 may be the same as or different from that of the second fixing portion 5313. When the material of the stopper 533 is different from the material of the second fixing portion 5313, the material of the stopper 533 may be the material of the stopper 535 of the first embodiment.

In the present embodiment, the stopper 533 is fixed to a side of the second fixing portion 5313 remote from the first fixing portion 5311 by glue or tape. In other embodiments, the stopper 533 and the second fixing portion 5313 may be integrally formed.

In addition, the first conductive segment 5314 is electrically connected to the first pin 511 of the first circuit board 51. The second conductive segment 5316 is electrically connected to the second pin 512 of the first circuit board 51.

In addition, the force application member 532 is SMA. One end of the force applying member 532 is connected to the first conductive segment 5314, and the other end is connected to the second fixing portion 5313. Thus, the first circuit board 51, the first conductive segment 5314, the urging member 532, the second fixing portion 5313, the connection portion 5312, and the second conductive segment 5316 form a current path.

It will be appreciated that the stopper 533 is configured to lock the first moving bracket 143 when the urging member 532 is energized. The energization of the biasing member 532 may be determined according to whether the first moving bracket 143 moves relatively. For example, when the first moving bracket 143 is not relatively moved, the urging member 532 is not energized. When the first moving bracket 143 moves relatively, the urging member 532 is energized. In addition, when the first moving bracket 143 is not relatively moved, the first moving bracket 143 is in a fixed position.

Specifically, when a current signal is applied to the force application member 532, the force application member 532 contracts. At this time, the urging member 532 generates a contraction force. In this way, the biasing member 532 in the contracted state can apply a tensile force to the second fixing portion 5313. When the second fixing portion 5313 receives a tensile force greater than the elastic force of the connecting portion 5312, the connecting portion 5312 is bent. Thus, the second fixing portion 5313 drives the stopper 533 to move.

Locking state: referring to fig. 43, fig. 43 is an enlarged schematic view of a portion of the camera module 100 shown in fig. 39 at E. When the first moving bracket 143 moves to the fixed position, the module circuit board 20 does not transmit the current signal to the first circuit board 51, and the force application member 532 is not energized. The force application member 532 is not contracted. The urging member 532 does not apply a tensile force to the second fixing portion 5313. At this time, the partial stopper 533 is located in the first through hole 521 of the first fastening member 52. The hole wall of the first through hole 521 may restrict the movement of the stopper 533. At this time, the first moving bracket 143 is in a locked state.

Unlocking state: referring to fig. 44, fig. 44 is a schematic diagram illustrating another state of the structure of the camera module 100 shown in fig. 4 in the fourth embodiment. When the first moving bracket 143 needs to move from the fixed position in the X-axis direction, the module circuit board 20 transmits a current signal to the first circuit board 51, and the urging member 532 is energized. The force application member 532 contracts. At this time, the urging member 532 generates a contraction force. In this way, the biasing member 532 in the contracted state can apply a tensile force to the second fixing portion 5313. When the second fixing portion 5313 receives a tensile force greater than the elastic force of the connecting portion 5312, the connecting portion 5312 is bent. Thus, the second fixing portion 5313 drives the stopper 533 to move. At this time, the stopper 533 is moved out of the first through hole 521 of the first fastening member 52. Thus, the first moving bracket 143 is in the unlocked state.

The structure of the camera module 100 is specifically described above. Hereinafter, another photographing method of the photographing module 100 will be described in conjunction with the above structure of the photographing module 100 (refer to fig. 38 to 44).

The photographing method of the photographing module 100 includes:

The energizing of the force applying member 532 is controlled so that the force applying member 532 applies a force to the stopper 535 to drive the stopper 535 to move out of the first through hole 521 against the elastic force of the elastic member 533.

In this embodiment, the force application member 532 is SMA. After the module circuit board 20 receives the photographing signal, the module circuit board 20 controls the energizing member 532 to be energized. At this time, the urging member 532 contracts. The force application member 532 generates a contractive force. In this way, the biasing member 532 in the contracted state can apply a tensile force to the second fixing portion 5313. When the second fixing portion 5313 receives a tensile force greater than the elastic force of the connecting portion 5312, the connecting portion 5312 is bent. Thus, the second fixing portion 5313 drives the stopper 533 to move. At this time, the stopper 533 is moved out of the first through hole 521 of the first fastening member 52.

The first moving bracket 143 is controlled to drive the first lens 151 to move from the fixed position to the target position along the optical axis direction of the optical lens 10.

It is understood that the fixed position refers to a position of the first moving bracket 143 within a moving stroke range. The position can be flexibly set according to the requirement. The target position refers to an arbitrary position of the first moving bracket 143 within the moving stroke range.

Specifically, the module circuit board 20 transmits a current signal to the first coil 146 through the lens circuit board 16. The first coil 146 is energized, and the first magnet 145 can generate a force along the negative X-axis direction to push the first moving support 143 to move along the negative X-axis direction under the action of the first coil 146. Thus, the first lens 151 fixed to the first moving bracket 143 can also move in the X-axis negative direction.

The second moving bracket 144 is controlled to drive the first lens 151 to move from the target position to the fixed position along the optical axis direction of the optical lens 10.

Specifically, the module circuit board 20 transmits a current signal to the first coil 146 through the lens circuit board 16. The first coil 146 is energized, and the first magnet 145 can generate an ampere force in the positive X-axis direction under the action of the first coil 146. At this time, the first magnet 145 pushes the first moving bracket 143 to move in the positive X-axis direction under an ampere force. In this way, the first lens 151 fixed to the first moving bracket 143 can also move in the X-axis positive direction.

It will be appreciated that by changing the direction of the current signal on the first coil 146, or by locating the S-pole or N-pole of the first magnet 145, the first magnet 145 can generate an ampere force in the positive X-axis direction when the first coil 146 is energized. At this time, the first magnet 145 can push the first moving bracket 143 to move in the positive X-axis direction under an ampere force.

The force application member 532 is controlled to be powered off, and the partial limiting block 535 stretches into the first through hole 521 under the elasticity of the elastic member 533.

Specifically, after the first moving bracket 143 moves to the fixed position, the module circuit board 20 controls the force application member 532 to be powered off. At this time, the urging member 532 is not energized, and the current signal does not act on the urging member 532. The force application member 532 is not contracted. At this time, the stopper 533 extends into the first through hole 521 of the first fastening member 52 under the elastic force of the connecting portion 5312. The hole wall of the first through hole 521 may restrict the movement of the stopper 533.

In one embodiment, in the "control the first moving bracket 143 to drive the first lens 151 to move from the fixed position to the target position along the optical axis direction of the optical lens 10", the method further includes:

It will be appreciated that the four camera modules 100 are specifically described above in connection with the accompanying drawings. Each camera module 100 is provided with a self-locking assembly 50. It can be understood that when the first lens 151 of the camera module 100 moves to the target position, the self-locking assembly 50 locks the motor, so that the stability of the first lens 151 on the motor 14 is better, that is, the first lens 151 on the motor 14 is not easy to move due to external shake or vibration, so that when a user is taking a photograph, the photographed image is not easy to deform or blur. Particularly, when the user takes a picture during the movement, the effect of the image taken by the camera module 100 is also better. Therefore, the image capturing module 100 of the present application also has better image capturing effect.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
