A camera module 10 according to an embodiment of the present invention is described below with reference to fig. 1.

As shown in fig. 1, a camera module 10 according to an embodiment of the present invention includes a housing 1, a lens assembly 2, a photosensitive assembly 3, and a rolling assembly 4.

Specifically, the housing 1 includes a bottom plate 11 and a housing bracket 12, the bottom plate 11 and the housing bracket 12 define a containing cavity 13, and the lens assembly 2, the photosensitive assembly 3 and the rolling assembly 4 are all disposed in the containing cavity 13.

For example, as shown in the figures, the housing bracket 12 has an opening, the lens assembly 2 is fixed at the opening, the lens assembly 2 includes a driving module 21 and a lens 22 inside the driving module 21, the driving module 21 is sleeved outside the lens 22 to drive the lens 22 to focus along the optical axis direction of the lens 22, here, for convenience of description, the up-down direction in fig. 1 is taken as a direction perpendicular to the plane of the bottom plate 11, and thus, the driving module 21 can drive the lens 22 to move along the up-down direction to perform a focusing action.

In some examples, the lens 22 may include a carrier and a lens group, the lens group is fixed on the carrier, and the driving module 21 may drive the carrier to move the lens group in the up-down direction to perform a focusing action.

However, in the process of the application of the actual camera module 10, when the camera module 10 is shaken, the shot picture is easily blurred, so the camera module 10 needs to be anti-shake, thereby ensuring the quality of the shot image. In the related art, the lens 22 is usually moved to achieve the anti-shake function, but the moving space of the lens 22 is limited by the assembly thereof, so that the moving space is limited, and the anti-shake function cannot achieve an ideal effect. In contrast, in the present application, the lens assembly 2 is fixed, and the anti-shake operation is performed by moving the photosensitive chip 31.

Specifically, the photosensitive assembly 3 includes a circuit board and a photosensitive chip 31 disposed on the circuit board, the photosensitive assembly 3 is movably disposed between the lens assembly 2 and the bottom plate 11, and the driving module 21 is further configured to drive the photosensitive assembly 3, so that the photosensitive assembly 3 moves relative to the lens assembly 2, for example, the driving module 21 may drive the photosensitive assembly 3 to move in a direction parallel to a plane of the bottom plate 11, where the direction parallel to the plane of the bottom plate 11 may refer to a length direction of the bottom plate 11, and may also refer to a width direction of the bottom plate 11, which is not limited herein. Therefore, according to the above description, the driving module 21 of the present application has two driving forms, that is, the driving module 21 can drive the lens 22 in the driving module 21, so that the lens 22 can perform a focusing operation in the up-down direction as shown in fig. 1, and can also drive the photosensitive assembly 3 to move in the left-right direction as shown in fig. 1, so that when the camera module 10 shakes, the photosensitive assembly 3 can better receive light, thereby improving the quality of a shot image and avoiding the blur of the shot picture. In addition, the camera module 10 of this application, move camera module 2 in the correlation technique relatively, this application is through moving photosensitive assembly 3, can utilize photosensitive assembly 3 to compare in the great space between casing 1 better, can make photosensitive assembly 3 move in great moving range, thereby guarantee photosensitive assembly 3's removal space, and then make camera module 10 when carrying out the anti-shake action, even the degree that camera module 10 trembles is great, camera module 10 also can realize better anti-shake effect. It should be noted that, the upper, lower, left and right directions used for indicating the orientation in the present application are schematic descriptions for convenience of description, and are not limitations of the present application.

Further, when the photosensitive assembly 3 is moved, due to the adjustment of the driven member, it is easy to cause some problems in moving and assembling the photosensitive assembly 3, for example, when moving, because a gap must be formed between the movable photosensitive assembly 3 and the lens assembly 2 and the bottom plate 11, so that the photosensitive assembly 3 can be moved well, and how to ensure the stability of the moving direction, and how to avoid the inclination of the photosensitive assembly 3, thereby affecting the light receiving of the photosensitive chip 31, and because a fixed distance needs to be maintained between the lens assembly 2 and the photosensitive assembly 3 to satisfy the imaging effect, how to reduce the assembling difficulty of the lens assembly 2 and the photosensitive assembly 3, etc., all bring great technical obstacles to the improvement of the camera module 10.

Based on this, in the present application, the rolling assembly 4 is provided, and the rolling assembly 4 includes a rolling member, the rolling member is located between the photosensitive assembly 3 and the lens assembly 2, and when the driving module drives the photosensitive assembly 3 to move relative to the lens assembly 2, the rolling member is used for enabling the photosensitive assembly 3 to move along a direction perpendicular to the optical axis of the lens 22. Therefore, by arranging the rolling piece and enabling the rolling piece to be positioned between the photosensitive component 3 and the lens component 2 to limit the distance between the lens component 2 and the photosensitive component 3, and further enabling the rolling piece to move relative to the moving part and the fixed part, in the assembling process, by arranging the rolling piece between the photosensitive component 3 and the lens component 2, the distance between the lens component 2 and the photosensitive component 3 can be well ensured when the photosensitive component 3 and the lens component 2 are assembled, so that the assembling difficulty of the lens component 2 and the photosensitive component 3 can be well reduced, meanwhile, in the moving process of the photosensitive component 3, the rolling piece can also move relative to the photosensitive component 3 and the lens component 2, in this way, the rolling piece can always limit the position of the photosensitive component 3, and the photosensitive component 3 can be prevented from inclining in the moving process, so that the photosensitive assembly 3 has better stability.

Here, the rolling member may be a ball 41, a roller, or another structure that can be supported between the photosensitive assembly and the lens assembly and can move relative to the photosensitive assembly and the lens assembly at the same time, and the application is not limited thereto.

Therefore, according to the camera module 10 of the embodiment of the present invention, in a manner of moving the photosensitive element 3 by fixing the lens assembly 2, light can be better projected onto the photosensitive chip 31 during the shaking process of the lens 22, so as to obtain a better imaging effect, and a larger moving space is provided between the photosensitive element 3 and the housing 1, so that the photosensitive element 3 can move within a larger moving range, and even if the degree of shaking of the camera module 10 is larger, the camera module 10 can also achieve a better anti-shaking effect. Further, still through setting up the rolling piece of the two relative distance of restriction at photosensitive assembly 3 and camera lens subassembly 2, the rolling piece can restrict photosensitive assembly 3's position all the time, can avoid photosensitive assembly 3 to take place the slope at the removal in-process, make photosensitive assembly 3 have better stability, in addition, when assembly photosensitive assembly 3 and camera lens subassembly 2, can guarantee the distance between camera lens subassembly 2 and the photosensitive assembly 3 betterly, thereby can reduce camera lens subassembly 2 and photosensitive assembly 3's the assembly degree of difficulty betterly.

That is to say, in the present application, the distance between the photosensitive component 3 and the lens component 2 is limited by the balls 41, and it should be further noted that, because in the actual imaging process, only the distance between the photosensitive chip 31 and the lens component 2 needs to be ensured, in the present application, the plurality of balls 41 are all disposed close to the photosensitive chip 31, and the distance between the photosensitive chip 31 and the lens component 2 can be better ensured in a manner of surrounding the photosensitive chip 31, here, for at least partially surrounding the photosensitive chip 31, it should be noted that, for example, the projection of the photosensitive chip 31 in the direction perpendicular to the bottom plate 11 is taken as an example, the projection of the photosensitive chip 31 is rectangular, the partially surrounding may be symmetrically disposed only in a square shape adjacent to two opposite sides of the photosensitive chip 31, that is, the partially surrounding means that the balls 41 are disposed only on two sides of the photosensitive chip 31 in a symmetrical manner, and does not completely surround the photosensitive chip 31, it is understood that the plurality of balls 41 may also completely surround the photosensitive chip 31, and is not limited thereto.

It should be noted that, by arranging the ball 41 between the lens assembly 2 and the photosensitive assembly 3, the friction between the lens assembly 2 and the photosensitive assembly 3 can be reduced, and meanwhile, the ball 41 can also better utilize the assembly gap between the lens assembly 2 and the photosensitive assembly 3, so that the height of the module can be reduced to a certain extent, and the thickness of the electronic device such as a mobile phone can be reduced.

It should be noted that, as shown in fig. 1, which is a cross-sectional view of the camera module 10, in fig. 1, the plurality of balls 41 are all located on the photosensitive chip 31, only the plurality of balls 41 are located on the photosensitive chip 31 in a visual angle, and in actual assembly, the balls 41 are arranged in a staggered manner on a projection perpendicular to the bottom plate 11 of the photosensitive chip 31, specifically, reference may be made to a relative position between the balls 41 and the photosensitive chip 31 in fig. 2. The relative position of the balls 41 and the photosensitive chip 31 in fig. 2 is only a schematic reference, and is not a specific limitation to the present application, and for example, the balls 41 may be provided only on two opposite sides of the photosensitive chip 31.

Further, the photosensitive element 31 corresponds to only about one third of the entire photosensitive assembly 3 in the left-right direction as shown in fig. 1, and thus, disposing the plurality of balls 41 adjacent to the photosensitive element 31 can allow the photosensitive assembly 3 to be disposed at a position other than the photosensitive element 31 without having to have high processing accuracy and assembling accuracy, which can reduce production cost and assembling cost.

Further, can set up the ball groove on at least one in camera lens subassembly 2 and the photosensitive assembly 3, also can set up the ball groove on camera lens subassembly 2, also can set up the ball groove on photosensitive assembly 3, can also set up the ball groove simultaneously on camera lens subassembly 2 and photosensitive assembly 3, and the ball groove can be better carry on spacingly to ball 41. Here, in one example, the ball groove may position the ball 41, that is, when the photosensitive assembly 3 moves, the ball 41 only rotates in the ball groove; in another example, the balls 41 may roll along the ball grooves, that is, the balls 41 roll along the ball grooves when the photosensitive assembly 3 moves.

Furthermore, the installation groove plate 42 may also be separately provided, that is, the ball groove for accommodating the ball 41 is provided on the installation groove plate 42, so that the lens assembly 2 or the photosensitive assembly 3 does not need to be further processed, and the processing difficulty of the lens assembly 2 and the photosensitive assembly 3 can be reduced. Here, the mounting groove plate 42 may be mounted on the lens assembly 2, the photosensitive assembly 3, or the lens assembly 2 and the photosensitive assembly 3, respectively, without limitation.

In some embodiments of the present invention, the driving module 21 includes a driving bracket 211, a first magnet 212 and a first coil 213, the first magnet 212 is disposed on the driving bracket 211, the first coil 213 is disposed on the photosensitive assembly 3, and the first coil 213 generates a magnetic field by being energized and interacts with the first magnet 212 to drive the photosensitive assembly 3 to move along a direction perpendicular to the optical axis of the lens 22, wherein the first magnet 212 and the first coil 213 are both provided in plurality, and on a projection plane perpendicular to the bottom plate 11, the plurality of first magnets 212 or the plurality of first coils 213 are both disposed on a side of the ball 41 away from the photosensitive chip 31.

That is to say, by integrally disposing the first magnet 212 and the second magnet on the same driving bracket 211, the degree of integration of the lens assembly 2 can be improved, and compared with disposing two driving devices to respectively drive the lens 22 and the photosensitive assembly 3, the difficulty in assembling the camera module 10 can be reduced, and the structure of the camera module 10 can be simplified.

Alternatively, the length of the suspension wire 51 may be greater than the length of the lens assembly 2 in the up-down direction as shown in fig. 1, wherein the lens assembly 2 may at least partially protrude out of the accommodating cavity, so that the suspension wire 51 is longer, and when the photosensitive assembly 3 is driven to move, the photosensitive assembly 3 may move in a smaller range, thereby enabling the photosensitive assembly 3 to have higher sensitivity.

In a specific embodiment, when the mobile phone shakes in a small range, the suspension wire 51 may allow the photosensitive component 3 to shake in a small range, thereby, when the photosensitive component 3 performs an anti-shake action in a small range, the mobile phone may have a high imaging effect and high sensitivity, so as to meet a high photographing requirement of a user. Wherein, the smaller range here means that the range of the shaking of the mobile phone can slightly influence the imaging quality. Further, when the mobile phone shakes in a larger range, the longer suspension wires 51 can allow the photosensitive assembly 3 to move in a larger range, and meanwhile, the photosensitive assembly 3 is not prone to tilting, so that the imaging quality is guaranteed.

Thus, the suspension wire 51 can be directly connected to the circuit board, and the structure of the photosensitive assembly 3 can be simplified. The suspension wire 51 and the lens assembly 2 are reserved with a sufficient swing distance, so that the suspension wire 51 cannot interfere with the lens assembly 2 in the swing process.

Furthermore, the suspension wires 51 can extend in the direction perpendicular to the bottom plate 11, so that after the photosensitive assembly 3 is lifted by the suspension wires 51, the suspension wires 51 can be guaranteed to have the same length, the suspension wires 51 can be guaranteed to have the same acting force, the photosensitive assembly 3 can be made to have good stability during assembly, and the difficulty in assembling the suspension wires 51 and the photosensitive assembly 3 can be reduced.
