[0002] With the development of science and technology, electronic devices are applied more and more widely. Generally, a camera module is installed on an electronic device to capture images, videos and the like. In the process of capturing by the electronic device, the electronic device may shake due to hand shaking of a user, and thus the captured images or videos are affected. Therefore, the camera module needs to be designed for anti-shaking. In the related art, the camera module is generally moved for anti-shaking, that is, in the process of shaking of the electronic device, the camera module is moved to offset the shaking of the camera module caused by the shaking of the electronic device, so as to improve the capturing effect of the camera module. However, in the related art, the quality and size of the camera module are large, which is not conducive to the installation of the camera module on the electronic device. SUMMARY

[0006] In the case that the driving assembly drives the movable assembly to move, the movable assembly drives the photosensitive chip to move, so that the position of the photosensitive chip changes relative to the lens module, and the camera module is compensated for shaking.

[0007] In a second aspect, embodiments of the application provide an electronic device, which comprises a device main body and the camera module in the first aspect.

Therefore, once the light is irradiated on the lens module, the light can pass through the lens module and irradiate on the photosensitive chip, so that the photosensitive chip converts the light into an image, so that the camera module realizes the shooting function. Since the driving assembly is connected with the movable assembly, once the driving assembly operates, the driving assembly can drive the movable assembly to move relative to the shell, so that the movable assembly drives the photosensitive chip to move, and the position of the photosensitive chip relative to the lens module changes, so that the shake compensation of the camera module is realized. That is, in the embodiment of the present application, by arranging the driving assembly in the shell, and fixing the photosensitive chip on the movable assembly, and connecting the movable assembly with the driving assembly, the driving assembly can drive the movable assembly to move, so that the position of the photosensitive chip relative to the shell changes, that is, the position of the photosensitive chip relative to the lens module changes, the shake compensation of the camera module is realized, and the driving assembly is equivalent to driving the photosensitive chip to move through the movable assembly.

[0019] like Figures 1 to 4 As shown, the camera module includes: housing 10, lens module 20, driving component 30, moving component 40, and photosensitive chip 50.

[0020] The lens module 20 is mounted on the housing 10, the drive component 30 is disposed in the housing 10, the photosensitive chip 50 is fixed to the movable component 40, the movable component 40 is connected to the housing 10, and the movable component 40 can move relative to the housing 10. The photosensitive chip 50 faces the lens module 20 so that light passing through the lens module 20 can illuminate the photosensitive chip 50. The drive component 30 is connected to the movable component 40 and is used to drive the movable component 40 to move. When the drive component 30 drives the movable component 40 to move, the movable component 40 drives the photosensitive chip 50 to move, so that the position of the photosensitive chip 50 relative to the lens module 20 changes, so as to compensate for the shake of the camera module.

[0021] In the embodiment of the present application, since the lens module 20 is mounted on the shell 10, the driving assembly 30 is arranged in the shell 10, the photosensitive chip 50 is fixed on the movable assembly 40, the movable assembly 40 is connected with the shell 10, and the photosensitive chip 50 faces the lens module 20. Therefore, once the light is irradiated on the lens module 20, the light can pass through the lens module 20 and irradiate on the photosensitive chip 50, so that the photosensitive chip 50 converts the light into an image, so that the camera module realizes the shooting function. Since the driving assembly 30 is connected with the movable assembly 40, once the driving assembly 30 operates, the driving assembly 30 can drive the movable assembly 40 to move relative to the shell 10, so that the movable assembly 40 drives the photosensitive chip 50 to move, and the position of the photosensitive chip 50 relative to the lens module 20 changes, so that the shake compensation of the camera module is realized. That is, in the embodiment of the present application, by arranging the driving assembly 30 in the shell 10, and fixing the photosensitive chip 50 on the movable assembly 40, and connecting the movable assembly 40 with the driving assembly 30, the driving assembly 30 can drive the movable assembly 40 to move, so that the position of the photosensitive chip 50 relative to the shell 10 changes, that is, the position of the photosensitive chip 50 relative to the lens module 20 changes, the shake compensation of the camera module is realized, and the driving assembly 30 is equivalent to driving the photosensitive chip 50 to move through the movable assembly 40. The weight of the photosensitive chip 50 is small, so that the size of the driving assembly 30 can be reduced, and the mass of the driving assembly 30 can be reduced, that is, in the embodiment of the present application, the size and mass of the driving assembly 30 can be reduced, so that the size and mass of the camera module are reduced, which is beneficial to the installation of the camera module on the electronic device.

[0022] In the process of shooting by the electronic device, if the electronic device shakes, the relative position of the lens module 20 and the photosensitive chip 50 in the camera module changes. In the related art, when the camera module is anti-shake, the lens module 20 of the camera module usually needs to move, so as to adjust the relative position of the lens module 20 and the photosensitive chip 50, and realize the effect of anti-shake. However, the size of the lens module 20 is usually large, and the mass is large, so the size of the driving assembly 30 for moving the lens module 20 is large, and the mass of the driving assembly 30 is large, which finally leads to the large size and mass of the camera module. In the embodiment of the present application, by arranging the driving assembly 30 in the shell 10, and fixing the photosensitive chip 50 on the movable assembly 40, and connecting the movable assembly 40 with the driving assembly 30, the driving assembly 30 can drive the movable assembly 40 to move, so that the position of the photosensitive chip 50 relative to the shell 10 changes, that is, the position of the photosensitive chip 50 relative to the lens module 20 changes, and the shake compensation of the camera module is realized. The weight of the photosensitive chip 50 is small, so that the size of the driving assembly 30 can be reduced, and the mass of the driving assembly 30 can be reduced, so that the size and mass of the camera module are reduced.

[0023] It should be noted that in the embodiments of the present application, the lens module 20 can include a lens barrel and a plurality of lenses arranged in the lens barrel.

[0024] In addition, in some embodiments, the driving assembly 30 can include a driving member 31 and a cooperating member 32; the driving member 31 is fixed to the inner wall of the shell 10, the cooperating member 32 is arranged in the shell 10, and the cooperating member 32 is movable relative to the shell 10; the cooperating member 32 is connected with the movable assembly 40, and the driving member 31 is used to drive the cooperating member 32 to move, so that the cooperating member 32 drives the movable assembly 40 to move.

[0025] Since the driving member 31 is fixed to the inner wall of the shell 10, and the cooperating member 32 is arranged in the shell 10 and movable relative to the shell 10, once the driving member 31 operates, the driving member 31 can drive the cooperating member 32 to move, that is, the cooperating member 32 moves relative to the shell 10 and the lens module 20. Since the cooperating member 32 is connected with the movable assembly 40, once the cooperating member 32 moves, the cooperating member 32 can drive the movable assembly 40 to move, so that the movable assembly 40 drives the photosensitive chip 50 to move, so that the position of the photosensitive chip 50 relative to the shell 10 and the lens module 20 changes, and the anti-shake compensation of the camera module is realized. That is, by arranging the driving member 31 and the cooperating member 32, the movable assembly 40 can be conveniently moved, and then the photosensitive chip 50 is moved.

[0026] In addition, in some embodiments, the driving assembly 30 can include a driving member 31 and a cooperating member 32; the driving member 31 is fixed to the inner wall of the shell 10, the cooperating member 32 is arranged in the shell 10, and the cooperating member 32 is movable relative to the shell 10; the cooperating member 32 is connected with the movable assembly 40, and the driving member 31 is used to drive the cooperating member 32 to move, so that the cooperating member 32 drives the movable assembly 40 to move.

[0027] Since the matching part 32 is fixed to the inner wall of the shell 10, the driving part 31 is arranged in the shell 10, and the driving part 31 is movable relative to the shell 10, therefore, once the driving part 31 operates, the driving part 31 can generate an acting force with the matching part 32, under the action of the acting force, the driving part 31 can move, that is, the driving part 31 moves relative to the shell 10 and the lens module 20. Since the driving part 31 is connected with the movable assembly 40, therefore, once the driving part 31 moves, the driving part 31 can drive the movable assembly 40 to move, so that the movable assembly 40 drives the photosensitive chip 50 to move, so that the position of the photosensitive chip 50 relative to the shell 10 and the lens module 20 changes, and the anti-shake compensation of the camera module is realized. That is, by arranging the driving part 31 and the matching part 32, the movable assembly 40 can be more conveniently moved, and then the photosensitive chip 50 is moved.

[0028] It should be noted that in the embodiment of the present application, the driving part 31 can be a conductive coil, and the matching part 32 can be a magnetic part, so that the conductive coil is energized, and the magnetic force can be generated between the conductive coil and the magnetic part, so that the conductive coil and the magnetic part repel each other or attract each other. If the driving part 31 is fixed to the inner wall of the shell 10, which is equivalent to that the conductive coil is fixed to the inner wall of the shell 10, at this time, the magnetic part can be movable relative to the shell 10, so that once the conductive coil is energized, the conductive coil and the magnetic part attract each other or repel each other, so that the magnetic part can move relative to the shell 10, so that the magnetic part drives the movable assembly 40 to move, so that the movable assembly 40 drives the photosensitive chip 50 to move; if the matching part 32 is fixed to the inner wall of the shell 10, which is equivalent to that the magnetic part is fixed to the inner wall of the shell 10, at this time, the conductive coil can be movable relative to the shell 10, so that once the conductive coil is energized, the conductive coil and the magnetic part attract each other or repel each other, so that the conductive coil can move relative to the shell 10, so that the conductive coil drives the movable assembly 40 to move, so that the movable assembly 40 drives the photosensitive chip 50 to move.

[0029] Of course, in the embodiment of the present application, the types of the driving part 31 and the matching part 32 can also be other types, for example, the driving part 31 can also be an electromagnet, and the matching part 32 is also an electromagnet, at this time, power can be supplied to the driving part 31 and the matching part 32 at the same time, so that the acting force is generated between the driving part 31 and the matching part 32, so that the driving part 31 and the matching part 32 move away from each other or move close to each other. The specific types of the driving part 31 and the matching part 32 are not limited in the embodiment of the present application.

[0030] In addition, in some embodiments, the camera module can also include a guide rod 60; both ends of the guide rod 60 are fixed in the shell 10, and the guide rod 60 extends along the axial direction of the shell 10, the matching part 32 is sleeved on the guide rod 60, and the matching part 32 is slidable along the extension direction of the guide rod 60.

[0031] Since the two ends of the guide rod 60 are fixed in the shell 10, and the matching piece 32 is sleeved on the guide rod 60, it is equivalent that the matching piece 32 can slide along the extension direction of the guide rod 60, so that once the driving piece 31 operates, the driving piece 31 can drive the matching piece 32 to move, so that the matching piece 32 can slide along the guide rod 60, so that the matching piece 32 drives the movable assembly 40 to move, and then the movable assembly 40 drives the photosensitive chip 50 to move. And by arranging the guide rod 60, the guide rod 60 can also play a guiding and limiting role for the matching piece 32 during the movement of the matching piece 32, so as to ensure that the matching piece 32 is relatively stable during the movement. That is, by arranging the guide rod 60, the stability of the matching piece 32 during the movement can be effectively improved, and the problem that the movement of the movable assembly 40 is affected due to the shaking of the matching piece 32 during the movement can be avoided.

[0032] It should be noted that in the embodiment of the present application, when the matching piece 32 is fixed to the inner wall of the shell 10, at this time, the driving piece 31 can be sleeved on the guide rod 60, and the driving piece 31 is connected with the movable assembly 40, and the driving piece 31 is slidable along the extension direction of the guide rod 60.

[0033] In addition, when the driving piece 31 is a conductive coil and the matching piece 32 is a magnetic piece, at this time, if the matching piece 32 is sleeved on the guide rod 60, it is equivalent to sleeving the magnetic piece on the guide rod 60; if the driving piece 31 is sleeved on the guide rod 60, it is equivalent to sleeving the conductive coil on the guide rod 60.

[0034] In addition, in some embodiments, the camera module can further include a sensor assembly; the sensor assembly is arranged in the driving piece 31, and the sensor assembly is used to detect the relative position of the driving piece 31 and the matching piece 32. Through such a setting, once the driving piece 31 drives the matching piece 32 to move, the sensor assembly can detect the relative position of the driving piece 31 and the matching piece 32, and then it is convenient to determine whether the movable assembly 40 has reached the position that needs to be anti-shake, that is, to determine whether the movement amount of the photosensitive chip 50 can effectively compensate for the shaking of the camera module. That is, by arranging the sensor assembly, it is convenient to determine whether the movement amount of the photosensitive chip 50 can compensate for the shaking of the camera module.

[0035] It should be noted that if it is determined that the movement amount of the photosensitive chip 50 can compensate for the jitter of the camera module, that is, the movement of the photosensitive chip 50 can compensate for the displacement amount of the lens module 20 relative to the photosensitive chip 50, the driving member 31 can stop driving the matching member 32 to move, so that the photosensitive chip 50 stops moving. If it is determined that the movement amount of the photosensitive chip 50 has not compensated for the jitter of the camera module, that is, the movement of the photosensitive chip 50 can compensate for the displacement amount of the lens module 20 relative to the photosensitive chip 50, the driving member 31 needs to drive the matching member 32 to move until the movement amount of the photosensitive chip 50 can compensate for the jitter of the camera module, that is, the movement of the photosensitive chip 50 can compensate for the displacement amount of the lens module 20 relative to the photosensitive chip 50.

[0036] In addition, when the matching member 32 is fixed to the inner wall of the shell 10, and the driving member 31 is movable relative to the shell 10, at this time, by arranging the sensor assembly, the relative position of the driving member 31 and the matching member 32 can also be determined, and then it can be determined whether the movement amount of the photosensitive chip 50 has effectively compensated for the jitter of the camera module.

[0037] It should be further noted that when the driving member 31 is a conductive coil and the matching member 32 is a magnetic member, at this time, the sensor assembly can include at least one of a Hall sensor and a magnetoresistance effect sensor.

[0038] In addition, in the embodiment of the present application, when the driving member 31 is a conductive coil and the matching member 32 is a magnetic member, if the matching member 32 is sleeved on the guide rod 60, a sleeving component can be arranged, and the magnetic member is attached to the sleeving component, so that once the sleeving component is sleeved on the guide rod 60, it is equivalent to that the magnetic member is sleeved on the guide rod 60. Of course, the magnetic member can also be directly sleeved on the guide rod 60. For this, the embodiment of the present application is not limited here.

[0039] In addition, in some embodiments, the camera module can further include a traction line 80 and a pulley assembly 90; the pulley assembly 90 is fixed in the shell 10, and the traction line 80 is wound around the pulley assembly 90, one end of the traction line 80 is connected with the matching member 32, and the other end of the traction line 80 is connected with the movable assembly 40.

[0040] Through such a setting, once the driving member 31 drives the matching member 32 to move along the guide rod 60, the matching member 32 can drive the movable assembly 40 to connect through the traction line 80, so that the movable assembly 40 drives the photosensitive chip 50 to move, and the anti-shake compensation of the camera module is realized. And by arranging the pulley assembly 90, the traction line 80 is wound around the pulley assembly 90, so as to change the direction of the traction line 80 through the pulley assembly 90, avoiding the matching member 32 and the movable assembly 40 in the same plane, which causes the problem of the large size of the shell 10.

[0041] In addition, in some embodiments, the pulley assembly 90 can include a fixed rod 91 and a pulley 92, one end of the fixed rod 91 is fixed to the inner wall of the shell 10, and the pulley 92 is rotatably connected to the other end of the fixed rod 91, and the traction line 80 is wound around the pulley.

[0042] Through such an arrangement, it can be ensured that the pulley is fixed in the shell 10, so that the pulley 92 cannot move with the traction line 80 during the movement of the cooperating piece 32, and the traction line 80 can effectively drive the movable assembly 40 to move. That is, by arranging the fixed rod 91 and the pulley 92, the pulley 92 can be fixed, and the traction line 80 can effectively drive the movable assembly 40 to move.

[0043] In addition, in some embodiments, the number of driving pieces 31 and the number of cooperating pieces 32 can be multiple; the shell 10 is fixed with driving pieces 31 on the inner wall opposite in the first direction, and in the first direction, one driving piece 31 corresponds to one cooperating piece 32; the shell 10 is fixed with driving pieces 31 on the inner wall opposite in the second direction, and in the second direction, one driving piece 31 corresponds to one cooperating piece 32; wherein the first direction and the second direction intersect, and the first direction and the second direction are both parallel to the light-sensing surface of the light-sensing chip 50.

[0044] Through such an arrangement, when it is necessary to compensate for the camera module in the first direction, the driving piece 31 in the first direction can drive the cooperating piece 32 to move, so that the movable assembly 40 moves, and the light-sensing chip 50 moves relative to the shell 10; when it is necessary to compensate for the camera module in the second direction, the driving piece 31 in the second direction can drive the cooperating piece 32 to move, so that the movable assembly 40 moves, and the light-sensing chip 50 moves relative to the shell 10. That is, through such an arrangement, the camera module can be compensated for in multiple directions, so that the shooting effect of the camera module can be improved.

[0045] For example, as shown in FIG. 8, when it is necessary to compensate for the camera module in the first direction, the driving piece 31 on the left in FIG. 8 can drive the cooperating piece 32 to move upward, and the driving piece 31 on the right in FIG. 8 can drive the cooperating piece 32 to move downward, so that the movable assembly 40 moves to the left. Figure 1 Figure 1 For example, as shown in FIG. 8, when it is necessary to compensate for the camera module in the first direction, the driving piece 31 on the left in FIG. 8 can drive the cooperating piece 32 to move upward, and the driving piece 31 on the right in FIG. 8 can drive the cooperating piece 32 to move downward, so that the movable assembly 40 moves to the left. Figure 1 Figure 1 For example, as shown in FIG. 8, when it is necessary to compensate for the camera module in the first direction, the driving piece 31 on the left in FIG. 8 can drive the cooperating piece 32 to move upward, and the driving piece 31 on the right in FIG. 8 can drive the cooperating piece 32 to move downward, so that the movable assembly 40 moves to the left.

[0046] ​​It should be noted that when the number of driving members 31 and the number of matching members 32 are both multiple, the number of pulley assemblies 90 is also multiple, and one pulley assembly 90 corresponds to one matching member 32, and the traction line 80 on one pulley assembly 90 can be connected to one matching member 32.

[0047] In addition, in some embodiments, the movable assembly 40 can include a circuit board 42; the circuit board 42 includes a first connecting portion 421, an elastic portion 422, and a second connecting portion 423, which are sequentially connected, the elastic portion 422 is deformable, the photosensitive chip 50 is fixed to the surface of the first connecting portion 421 away from the lens module 20, the surface of the second connecting portion 423 facing the lens is fixedly connected with the shell 10, the first connecting portion is connected with the driving assembly 30, and the driving assembly 30 is used to drive the first connecting portion 421 to move; under the condition that the driving assembly 30 drives the first connecting portion 421 to move, the first connecting portion 421 drives the elastic portion 422 to deform, so that the position of the first connecting portion 421 relative to the lens module 20 changes, and the position of the photosensitive chip 50 relative to the lens module 20 changes.

[0048] Since the first connecting portion 421, the elastic portion 422, and the second connecting portion 423 are sequentially connected, and the elastic portion 422 is deformable, once the first connecting portion 421 is stressed, the first connecting portion 421 can drive the elastic portion 422 to deform, so that the position of the first connecting portion 421 relative to the lens module 20 changes. Since the photosensitive chip 50 is fixed to the surface of the first connecting portion 421 away from the lens module 20, the surface of the second connecting portion 423 facing the lens is fixedly connected with the shell 10, and the first connecting portion is connected with the driving assembly 30, once the driving assembly 30 operates, the driving assembly 30 can apply force to the first connecting portion 421, the first connecting portion 421 can apply force to the elastic portion 422, so that the elastic portion 422 deforms, thereby changing the position of the first connecting portion 421, i.e., changing the position of the first connecting portion 421 relative to the lens module 20, and further changing the position of the photosensitive chip 50 relative to the lens module 20. That is, by arranging the first connecting portion 421, the elastic portion 422, and the second connecting portion 423, the movement of the photosensitive chip 50 can be facilitated.

[0049] In addition, in the embodiments of the present application, the circuit board 42 can also include a connector connected with the second connecting portion 423.

[0050] In addition, in some embodiments, the elastic portion 422 surrounds the first connecting portion 421, and the second connecting portion 423 surrounds the elastic portion 422, and the elastic portion 422 is connected with the first connecting portion 421 and the second connecting portion 423 respectively.

[0051] Through the arrangement, once the first connecting part 421 is subjected to force, the first connecting part 421 can apply force to the elastic part 422, and the elastic part 422 surrounds the first connecting part 421, so that no matter in which direction the first connecting part 421 is subjected to force, the first connecting part 421 can apply force to the elastic part 422, and thus the first connecting part 421 can move in any direction, so that the photosensitive chip 50 can move relative to the lens module 20 in any direction, and the anti-shake effect of the camera module is improved.

[0052] In addition, in some embodiments, the camera module can further include a filter seat 41; the filter seat 41 is fixed to the surface of the first connecting part 421 facing the lens module 20, and the filter seat 41 is connected with the driving assembly 30, and the driving assembly 30 is used to drive the filter seat 41 to move, so as to drive the first connecting part 421 to move; under the action of the driving assembly 30, the filter seat 41 drives the first connecting part 421 to move, so that the first connecting part 421 drives the elastic part 422 to deform.

[0053] Since the filter seat 41 is fixed to the surface of the first connecting part 421 facing the lens module 20, and the filter seat 41 is connected with the driving assembly 30, it is equivalent that the driving assembly 30 is connected with the first connecting part 421 through the filter seat 41, so that the driving assembly 30 and the first connecting part 421 can be connected without using other connecting devices, and the components inside the camera module can be reused, that is, the filter seat 41 is reused, so that the cost of the camera module is reduced, and once the driving assembly 30 operates, the driving assembly 30 can apply force to the filter seat 41, so that the filter seat 41 applies force to the first connecting part 421, and the first connecting part 421 can apply force to the elastic part 422, so that the elastic part 422 deforms, and thus the position of the first connecting part 421 changes, so as to realize the effect of changing the position of the photosensitive chip 50 relative to the lens module 20. That is, by arranging the filter seat 41, the driving assembly 30 can drive the first connecting part 421 to change the position.

[0054] It should be noted that in the embodiments of the present application, a filter can be arranged on the filter seat 41, and the filter is located between the photosensitive chip 50 and the lens module 20. The filter can be an infrared filter.

[0055] In addition, in the embodiments of the present application, when the driving assembly 30 includes the driving part 31 and the cooperating part 32, if the driving part 31 is fixed to the inner wall of the shell 10, the cooperating part 32 is connected with the filter seat 41 through the traction line 80; if the cooperating part 32 is fixed to the inner wall of the shell 10, the driving part 31 is connected with the filter seat 41 through the traction line 80.

[0056] Additionally, in some embodiments, such as Figure 3 As shown, both the elastic portion 422 and the second connecting portion 423 are hollow structures. The first connecting portion 421 is located inside the elastic portion 422, and the elastic portion 422 is located inside the second connecting portion 423. The elastic portion 422 is connected to both the first connecting portion 421 and the second connecting portion 423; or, as shown... Figure 4 As shown, the second connecting part 423 is a hollow structure, and there are multiple elastic parts 422. The multiple elastic parts 422 are distributed at intervals along the circumferential direction of the first connecting part 421, and the multiple elastic parts 422 and the first connecting part 421 are all located inside the second connecting part 423. The elastic parts 422 are connected to the first connecting part 421 and the second connecting part 422 respectively.

[0057] When both the elastic portion 422 and the second connecting portion 423 are hollow structures, the first connecting portion 421 can be disposed inside the elastic portion 422, effectively surrounding the first connecting portion 421. The elastic portion 422 is also disposed inside the second connecting portion 423. The elastic portion 422 is connected to both the first and second connecting portions 421. Therefore, once the first connecting portion 421 is subjected to force, it can apply force to the elastic portion 422, causing the elastic portion 422 to deform and thus changing the position of the first connecting portion 421. Regardless of the direction of the force applied to the first connecting portion 421, it can be ensured that the first connecting portion 421 applies force to the elastic portion 422, causing the position of the first connecting portion 421 to change.

[0058] When the second connecting portion 423 is a hollow structure and there are multiple elastic portions 422, the multiple elastic portions 422 can be distributed at intervals along the circumferential direction of the first connecting portion 421, which is equivalent to the elastic portions 422 surrounding the first connecting portion 421. Both the elastic portions 422 and the first connecting portion 421 are disposed inside the second connecting portion 423. The elastic portions 422 are connected to both the first connecting portion 421 and the second connecting portion 422. Therefore, once the first connecting portion 421 is subjected to force, it can apply force to the elastic portions 422, causing the elastic portions 422 to deform and thus changing the position of the first connecting portion 421. Regardless of the direction of the force applied to the first connecting portion 421, it can be ensured that the first connecting portion 421 applies force to the elastic portions 422, causing the position of the first connecting portion 421 to change.

[0059] In the embodiment of the present application, since the lens module 20 is mounted on the shell 10, the driving assembly 30 is arranged in the shell 10, the photosensitive chip 50 is fixed on the movable assembly 40, the movable assembly 40 is connected with the shell 10, and the photosensitive chip 50 faces the lens module 20, therefore, once the light is irradiated on the lens module 20, the light can pass through the lens module 20 and irradiate on the photosensitive chip 50, so that the photosensitive chip 50 converts the light into an image, so that the camera module realizes the shooting function. Since the driving assembly 30 is connected with the movable assembly 40, therefore, once the driving assembly 30 operates, the driving assembly 30 can drive the movable assembly 40 to move relative to the shell 10, so that the movable assembly 40 drives the photosensitive chip 50 to move, and the position of the photosensitive chip 50 relative to the lens module 20 changes, so that the shake compensation of the camera module is realized. That is, in the embodiment of the present application, by arranging the driving assembly 30 in the shell 10, and fixing the photosensitive chip 50 on the movable assembly 40, and connecting the movable assembly 40 with the driving assembly 30, so that the driving assembly 30 can drive the movable assembly 40 to move, so that the position of the photosensitive chip 50 relative to the shell 10 changes, that is, the position of the photosensitive chip 50 relative to the lens module 20 changes, the shake compensation of the camera module is realized, and the driving assembly 30 is equivalent to drive the photosensitive chip 50 to move through the movable assembly 40, the weight of the photosensitive chip 50 is small, so that the size of the driving assembly 30 can be reduced, and the mass of the driving assembly 30 can be reduced, that is, in the embodiment of the present application, the size and the mass of the driving assembly 30 can be reduced, so that the size and the mass of the camera module are reduced, which is beneficial to the installation of the camera module on the electronic device.
