Description

Technical Field

[0001] The present application belongs to the field of cameras, and specifically relates to a camera module and an electronic device. Background Art

[0002] With the development of science and technology, the application of electronic devices is becoming more and more extensive. Usually, a camera module is installed on an electronic device, and images, videos, etc. are captured by the camera module. In the process of shooting through an electronic device, the electronic device may shake due to the shaking of the user's hands, causing the captured image or video to be affected. Therefore, it is necessary to design an anti-shake for the camera module. In the related art, the camera module is usually anti-shake by driving the lens of the camera module to move, that is, in the process of shaking of the electronic device, by moving the lens, the amount of lens shaking, for example, the shaking of the electronic device causes the lens to move to the left, then the lens is moved to the right, thereby offsetting the amount of camera module shaking caused by the shaking of the electronic device, and improving the shooting effect of the camera module. However, in the related art, the mass and size of the camera module are relatively large, which is not conducive to the installation of the camera module on the electronic device. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a camera module and an electronic device, which at least solves the problem that the camera module has a large mass and size, which is not conducive to the installation of the camera module on the electronic device.

[0004] In a first aspect, an embodiment of the present application provides a camera module, the camera module comprising: a housing, a lens module, a driving component, a movable component and a photosensitive chip;

[0005] The lens module is mounted on the housing, the driving assembly is disposed in the housing, the photosensitive chip is fixed to the movable assembly, the movable assembly is connected to the housing, the movable assembly can move relative to the housing, the photosensitive chip faces the lens module, so that the light passing through the lens module can irradiate the photosensitive chip, the driving assembly is connected to the movable assembly, and the driving assembly is used to drive the movable assembly to move;

[0006] When the driving component drives the movable component to move, the movable component drives the photosensitive chip to move, so that the position of the photosensitive chip relative to the lens module changes, so as to perform jitter compensation for the camera module.

[0007] In a second aspect, an embodiment of the present application provides an electronic device, the electronic device comprising a device body and the camera module described in the first aspect above;

[0008] The camera module is installed on the device body.

[0009] In the embodiment of the present application, since the lens module is mounted on the housing, the driving component is disposed in the housing, the photosensitive chip is fixed to the movable component, the movable component is connected to the housing, and the photosensitive chip faces the lens module, therefore, once 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 component is connected to the movable component, once the driving component is running, the driving component can drive the movable component to move relative to the housing, so that the movable component drives the photosensitive chip to move, and the position of the photosensitive chip relative to the lens module will change, thereby realizing the jitter compensation of the camera module. That is, in the embodiment of the present application, a driving component is provided in the shell, and the photosensitive chip is fixed to the movable component, and the movable component is connected to the driving component, so that the driving component can drive the movable component 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, and the camera module is compensated for jitter, and the driving component is equivalent to driving the photosensitive chip to move through the movable component. The weight of the photosensitive chip is small, so that the size of the driving component can be reduced, and the mass of the driving component can be reduced. That is, in the embodiment of the present application, the size and mass of the driving component can be reduced, thereby reducing the size and mass of the camera module, which is beneficial to the installation of the camera module on the electronic device.

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

[0020] The lens module 20 is installed on the shell 10, the driving component 30 is arranged in the shell 10, the photosensitive chip 50 is fixed to the movable component 40, the movable component 40 is connected to the shell 10, the movable component 40 can move relative to the shell 10, the photosensitive chip 50 faces the lens module 20, so that the light passing through the lens module 20 can be irradiated on the photosensitive chip 50, the driving component 30 is connected to the movable component 40, and the driving component 30 is used to drive the movable component 40 to move; when the driving 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 jitter of the camera module.

[0021] In the embodiment of the present application, since the lens module 20 is mounted on the housing 10, the driving assembly 30 is disposed in the housing 10, the photosensitive chip 50 is fixed to the movable assembly 40, the movable assembly 40 is connected to the housing 10, and the photosensitive chip 50 faces the lens module 20, therefore, once 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 to the movable assembly 40, once the driving assembly 30 is running, the driving assembly 30 can drive the movable assembly 40 to move relative to the housing 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 will change, thereby realizing the jitter compensation of the camera module. That is, in the embodiment of the present application, by setting the driving component 30 in the shell 10, fixing the photosensitive chip 50 on the movable component 40, and connecting the movable component 40 with the driving component 30, the driving component 30 can drive the movable component 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 camera module is compensated for jitter, and the driving component 30 is equivalent to driving the photosensitive chip 50 to move through the movable component 40. The weight of the photosensitive chip 50 is relatively small, so that the size of the driving component 30 can be reduced, and the mass of the driving component 30 can be reduced. That is, in the embodiment of the present application, the size and mass of the driving component 30 can be reduced, thereby reducing the size and mass of the camera module, which is beneficial to the installation of the camera module on the electronic device.

[0022] In the process of shooting through an electronic device, if the electronic device shakes, the relative position of the lens module 20 and the photosensitive chip 50 in the camera module will change. In the related art, when the camera module is anti-shake, the lens module 20 of the camera module is usually required to move, so as to adjust the relative position of the lens module 20 and the photosensitive chip 50 to achieve the anti-shake effect, but the lens module 20 is usually large in size and mass, so the size of the driving component 30 that needs to move the lens module 20 will be large, and then the mass of the driving component 30 will be large, which ultimately leads to the size and mass of the camera module. In the embodiment of the present application, by setting the driving component 30 in the housing 10, and fixing the photosensitive chip 50 to the movable component 40, and connecting the movable component 40 with the driving component 30, the driving component 30 can drive the movable component 40 to move, so that the position of the photosensitive chip 50 relative to the housing 10 changes, that is, the position of the photosensitive chip 50 relative to the lens module 20 changes, and the camera module is shake compensated. The light-sensitive chip 50 is relatively light in weight, so that the size of the driving component 30 can be reduced, and the mass of the driving component 30 can be reduced, thereby reducing the size and mass of the camera module.

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

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

[0025] Since the driving member 31 is fixed to the inner wall of the housing 10, the matching member 32 is arranged in the housing 10, and the matching member 32 is movable relative to the housing 10, once the driving member 31 is running, the driving member 31 can drive the matching member 32 to move, that is, the matching member 32 moves relative to the housing 10 and the lens module 20. Since the matching member 32 is connected to the movable component 40, once the matching member 32 moves, the matching member 32 can drive the movable component 40 to move, so that the movable component 40 drives the photosensitive chip 50 to move, so that the position of the photosensitive chip 50 relative to the housing 10 and the lens module 20 changes, and the anti-shake compensation of the camera module is realized. That is, by setting the driving member 31 and the matching member 32, it is relatively convenient to make the movable component 40 move, and then make the photosensitive chip 50 move.

[0026] In addition, in some embodiments, the driving component 30 may include a driving member 31 and a matching member 32; the matching member 32 is fixed to the inner wall of the shell 10, the driving member 31 is arranged in the shell 10, and the driving member 31 is movable relative to the shell 10, a force can be generated between the driving member 31 and the matching member 32, and the driving member 31 is connected to the movable component 40; when a force is generated between the driving member 31 and the matching member 32, the driving member 31 moves relative to the shell 10 to drive the movable component 40 to move, and the movable component 40 drives the photosensitive chip 50 to move.

[0027] Since the matching piece 32 is fixed to the inner wall of the housing 10, the driving piece 31 is arranged in the housing 10, and the driving piece 31 is movable relative to the housing 10, once the driving piece 31 is in operation, a force can be generated between the driving piece 31 and the matching piece 32, and the driving piece 31 can move under the action of the force, that is, the driving piece 31 moves relative to the housing 10 and the lens module 20. Since the driving piece 31 is connected to the movable component 40, once the driving piece 31 moves, the driving piece 31 can drive the movable component 40 to move, so that the movable component 40 drives the photosensitive chip 50 to move, so that the position of the photosensitive chip 50 relative to the housing 10 and the lens module 20 changes, and the anti-shake compensation of the camera module is realized. That is, by setting the driving piece 31 and the matching piece 32, it is relatively convenient to make the movable component 40 move, and then make the photosensitive chip 50 move.

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

[0029] Of course, in the embodiment of the present application, the types of the driving member 31 and the matching member 32 can also be other types. For example, the driving member 31 can also be an electromagnet, and the matching member 32 can also be an electromagnet. In this case, power can be supplied to the driving member 31 and the matching member 32 at the same time, so that a force is generated between the driving member 31 and the matching member 32, so that the driving member 31 and the matching member 32 move away from or approach each other. The embodiment of the present application does not limit the specific types of the driving member 31 and the matching member 32.

[0030] In addition, in some embodiments, the camera module may further 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 piece 32 is sleeved on the guide rod 60, and the matching piece 32 can slide along the extension direction of the guide rod 60.

[0031] Since both ends of the guide rod 60 are fixed in the housing 10, and the matching piece 32 is sleeved on the guide rod 60, it is equivalent to that the matching piece 32 can slide along the extension direction of the guide rod 60, so that once the driving member 31 is running, the driving member 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 component 40 to move, and then the movable component 40 drives the photosensitive chip 50 to move. In addition, by setting the guide rod 60, during the movement of the matching piece 32, the guide rod 60 can also play a guiding and limiting role for the matching piece 32, ensuring that the matching piece 32 is relatively stable during the movement. That is, by setting the guide rod 60, the stability of the matching piece 32 during the movement can be effectively improved, and the matching piece 32 can be prevented from shaking during the movement, which causes the activity of the movable component 40 to be affected.

[0032] It should be noted that in the embodiment of the present application, when the fitting 32 is fixed to the inner wall of the shell 10 , the driving member 31 can be sleeved on the guide rod 60 , and the driving member 31 is connected to the movable component 40 , and the driving member 31 can slide along the extension direction of the guide rod 60 .

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

[0034] In addition, in some embodiments, the camera module may further include a sensor component; the sensor component is disposed in the driving member 31, and the sensor component is used to detect the relative position of the driving member 31 and the matching member 32. Through such a configuration, once the driving member 31 drives the matching member 32 to move, the sensor component can detect the relative position of the driving member 31 and the matching member 32, and then it is convenient to determine whether the movable component 40 has reached the position where anti-shake is required according to the relative position of the driving member 31 and the matching member 32, that is, to determine whether the movement of the photosensitive chip 50 can effectively compensate for the jitter of the camera module. That is, by setting the sensor component, it is convenient to determine whether the movement of the photosensitive chip 50 can compensate for the jitter of the camera module.

[0035] It should be noted that if it is determined that the movement of the photosensitive chip 50 can compensate for the shaking of the camera module, that is, the movement of the photosensitive chip 50 can compensate for the displacement 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 of the photosensitive chip 50 has not yet compensated for the shaking of the camera module, that is, the movement of the photosensitive chip 50 can compensate for the displacement of the lens module 20 relative to the photosensitive chip 50, it is necessary to drive the matching member 32 to move until the movement of the photosensitive chip 50 can compensate for the shaking of the camera module, that is, the movement of the photosensitive chip 50 can compensate for the displacement of the lens module 20 relative to the photosensitive chip 50.

[0036] In addition, when the matching piece 32 is fixed to the inner wall of the shell 10 and the driving piece 31 is movable relative to the shell 10, at this time, by setting up a sensor component, the relative position of the driving piece 31 and the matching piece 32 can also be determined, and then it can be determined whether the movement amount of the photosensitive chip 50 is sufficient to effectively compensate for the jitter of the camera module.

[0037] It should also be noted that when the driving member 31 is a conductive coil and the matching member 32 is a magnetic member, the sensor component may include at least one of a Hall sensor and a magnetoresistive 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 sleeve component can be provided to attach the magnetic member to the sleeve component, so that once the sleeve component is sleeved on the guide rod 60, it is equivalent to the magnetic member being sleeved on the guide rod 60. Of course, the magnetic member can also be directly sleeved on the guide rod 60. In this regard, the embodiment of the present application is not limited here.

[0039] In addition, in some embodiments, the camera module may also include a traction line 80 and a pulley assembly 90; the pulley assembly 90 is fixed in the housing 10, and the traction line 80 is wound around the pulley assembly 90, one end of the traction line 80 is connected to the mating piece 32, and the other end of the traction line 80 is connected to the movable assembly 40.

[0040] Through such a configuration, 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, thereby realizing the anti-shake compensation of the camera module. And by setting the pulley assembly 90, the traction line 80 is wound around the pulley assembly 90, which is equivalent to changing the direction of the traction line 80 through the pulley assembly 90, avoiding the matching member 32 and the movable assembly 40 being in the same plane, resulting in the problem of a larger size of the housing 10.

[0041] In addition, in some embodiments, the pulley assembly 90 may 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, 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] By such a configuration, it is ensured that the pulley is fixed in the housing 10, so that the pulley 92 does not move with the pulley 80 when the traction line 80 moves with the fitting 32, and the traction line 80 can effectively pull the movable assembly 40 to move. That is, by providing the fixing rod 91 and the pulley 92, it is convenient to fix the pulley 92, and it is ensured that the traction line 80 can effectively pull the movable assembly 40 to move.

[0043] In addition, in some embodiments, the number of driving members 31 and the number of matching members 32 can both be multiple; the driving members 31 are fixed on the inner walls of the shell 10 opposite to each other in the first direction, and in the first direction, one driving member 31 corresponds to one matching member 32; the driving members 31 are fixed on the inner walls of the shell 10 opposite to each other in the second direction, and in the second direction, one driving member 31 corresponds to one matching member 32; wherein the first direction intersects with the second direction, and both the first direction and the second direction are parallel to the photosensitive surface of the photosensitive chip 50.

[0044] Through such a setting, when the camera module needs to be anti-shake compensated in the first direction, the driving member 31 in the first direction can drive the matching member 32 to move, so that the movable component 40 moves, and the photosensitive chip 50 moves relative to the housing 10; when the camera module needs to be anti-shake compensated in the second direction, the driving member 31 in the second direction can drive the matching member 32 to move, so that the movable component 40 moves, and the photosensitive chip 50 moves relative to the housing 10. That is, through such a setting, the camera module can be anti-shake compensated in multiple directions, so as to improve the shooting effect of the camera module.

[0045] For example, Figure 1 As shown, when the camera module needs to be anti-shake compensated in the first direction, it can make Figure 1 The driving member 31 on the left drives the matching member 32 to move upward, and makes Figure 1 The driving member 31 on the right side drives the matching member 32 to move downward, so that the movable component 40 moves to the left. Figure 1 The up, down, left, and right directions are merely exemplary and do not represent the actual directions of the camera module provided in the embodiments of the present application.

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

[0047] In addition, in some embodiments, the movable component 40 may 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, the first connecting portion 421, the elastic portion 422 and the second connecting portion 423 are connected in sequence, the elastic portion 422 can be deformed, the photosensitive chip 50 is fixed to the surface of the first connecting portion 421 away from the lens module 20, the second connecting portion 423 is fixedly connected to the surface of the housing 10 facing the lens, the first connecting portion is connected to the driving component 30, and the driving component 30 is used to drive the first connecting portion 421 to move; when the driving component 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 connection part 421, the elastic part 422 and the second connection part 423 are connected in sequence, the elastic part 422 can be deformed. Therefore, once the first connection part 421 is subjected to force, the first connection part 421 can drive the elastic part 422 to deform, thereby changing the position of the first connection part 421 relative to the lens module 20. Since the photosensitive chip 50 is fixed to the surface of the first connection part 421 away from the lens module 20, the surface of the second connection part 423 facing the lens is fixedly connected to the housing 10, and the first connection part is connected to the driving assembly 30, once the driving assembly 30 is running, the driving assembly 30 can apply force to the first connection part 421, and the first connection part 421 will apply force to the elastic part 422, so that the elastic part 422 is deformed, thereby changing the position of the first connection part 421, that is, changing the position of the first connection part 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 providing the first connecting portion 421 , the elastic portion 422 and the second connecting portion 423 , the photosensitive chip 50 can be easily moved.

[0049] In addition, in the embodiment of the present application, the circuit board 42 may further include a connector, and the connector is connected to the second connecting portion 423 .

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

[0051] Through such a configuration, 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, which can ensure that no matter what direction the force on the first connecting part 421 is subjected to, the first connecting part 421 can apply force to the elastic part 422, so that the first connecting part 421 can move in any direction, thereby ensuring that the photosensitive chip 50 can move in any direction relative to the lens module 20, thereby improving the anti-shake effect on the camera module.

[0052] In addition, in some embodiments, the camera module may further include a filter base 41; the filter base 41 is fixed to the surface of the first connecting part 421 facing the lens module 20, and the filter base 41 is connected to the driving assembly 30, and the driving assembly 30 is used to drive the filter base 41 to move, so as to drive the first connecting part 421 to move; when the driving assembly 30 drives the filter base 41 to move, the filter base 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 base 41 is fixed to the surface of the first connection part 421 facing the lens module 20, the filter base 41 is connected to the driving assembly 30, and therefore, it is equivalent to connecting the driving assembly 30 with the first connection part 421 through the filter base 41, so that it is possible to avoid using other additional connection devices to connect the driving assembly 30 with the first connection part 421, so that the components inside the camera module can be reused, that is, it is equivalent to reusing the filter base 41, which can reduce the cost of the camera module, and once the driving assembly 30 is running, the driving assembly 30 can apply force to the filter base 41, so that the filter base 41 applies force to the first connection part 421, and the first connection part 421 can apply force to the elastic part 422, so that the elastic part 422 is deformed, so that the position of the first connection part 421 will change, and the effect of changing the position of the photosensitive chip 50 relative to the lens module 20 is achieved. That is, by providing the filter base 41, it is convenient for the driving assembly 30 to drive the position change of the first connection part 421.

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

[0055] In addition, in the embodiment of the present application, when the driving component 30 includes a driving member 31 and a matching member 32, at this time, if the driving member 31 is fixed to the inner wall of the shell 10, the matching member 32 is connected to the filter base 41 through the traction line 80; if the matching member 32 is fixed to the inner wall of the shell 10, the driving member 31 is connected to the filter base 41 through the traction line 80.

[0056] In addition, in some embodiments, Figure 3 As shown, the elastic part 422 and the second connecting part 423 are both hollow structures, the first connecting part 421 is located inside the elastic part 422, the elastic part 422 is located inside the second connecting part 423, and the elastic part 422 is connected to the first connecting part 421 and the second connecting part 422 respectively; or Figure 4 As shown, the second connection 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 connection part 421, and the multiple elastic parts 422 and the first connection part 421 are all located inside the second connection part 423, and the elastic parts 422 are respectively connected to the first connection part 421 and the second connection part 422.

[0057] When both the elastic part 422 and the second connecting part 423 are hollow structures, the first connecting part 421 can be arranged inside the elastic part 422, which is equivalent to the elastic part 422 surrounding the first connecting part 421, and the elastic part 422 is arranged inside the second connecting part 423, and the elastic part 422 is connected to the first connecting part 421 and the second connecting part 422 respectively, so that once the first connecting part 421 is subjected to force, the first connecting part 421 can apply force to the elastic part 422, so that the elastic part 422 is deformed, and the position of the first connecting part 421 changes. And no matter what direction the first connecting part 421 is subjected to force, it can be ensured that the first connecting part 421 applies force to the elastic part 422, so that the position of the first connecting part 421 changes.

[0058] When the second connection part 423 is a hollow structure and the number of the elastic parts 422 is multiple, the multiple elastic parts 422 can be distributed at intervals along the circumferential direction of the first connection part 421, which is equivalent to the elastic parts 422 surrounding the first connection part 421, and the elastic parts 422 and the first connection part 421 are both arranged inside the second connection part 423, and the elastic parts 422 are respectively connected to the first connection part 421 and the second connection part 422, so that once the first connection part 421 is subjected to force, the first connection part 421 can apply force to the elastic part 422, so that the elastic part 422 is deformed, and the position of the first connection part 421 changes. And no matter what direction the first connection part 421 is subjected to force, it can be ensured that the first connection part 421 applies force to the elastic part 422, so that the position of the first connection part 421 changes.

[0059] In the embodiment of the present application, since the lens module 20 is mounted on the housing 10, the driving assembly 30 is disposed in the housing 10, the photosensitive chip 50 is fixed to the movable assembly 40, the movable assembly 40 is connected to the housing 10, and the photosensitive chip 50 faces the lens module 20, therefore, once 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 to the movable assembly 40, once the driving assembly 30 is running, the driving assembly 30 can drive the movable assembly 40 to move relative to the housing 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 will change, thereby realizing the jitter compensation of the camera module. That is, in the embodiment of the present application, by setting the driving component 30 in the shell 10, fixing the photosensitive chip 50 on the movable component 40, and connecting the movable component 40 with the driving component 30, the driving component 30 can drive the movable component 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 camera module is compensated for jitter, and the driving component 30 is equivalent to driving the photosensitive chip 50 to move through the movable component 40. The weight of the photosensitive chip 50 is relatively small, so that the size of the driving component 30 can be reduced, and the mass of the driving component 30 can be reduced. That is, in the embodiment of the present application, the size and mass of the driving component 30 can be reduced, thereby reducing the size and mass of the camera module, which is beneficial to the installation of the camera module on the electronic device.
