The camera module 20 may include a lens mount 21, a lens 22, a carrier assembly 23, and a lens driving mechanism (not shown). The bearing assembly 23 is disposed on the lens base 21, and the lens 22 is disposed on the bearing assembly 23 and supported by the bearing assembly 23. Wherein, the lens mount 21 is provided with an installation space 211, the bearing assembly 23 and a lens driving mechanism are arranged in the installation space 211 of the lens mount 21, and the lens driving mechanism is used for driving the bearing assembly 23 to move along the direction parallel to the optical axis of the lens so as to realize focusing of the lens.

For example, the lens driving mechanism may employ an electromagnetic motor, for example, the lens driving mechanism may include a magnetic member and an electrically conductive member, one of which is disposed on the carrier member 23, and the other of which is disposed on the lens mount 21, and the electrically conductive member is capable of cooperating with the magnetic member in an energized state to enable the carrier member 23 to move in a direction parallel to the optical axis of the lens 22, so as to drive the carrier member 23 and the lens 22 to move together in a direction parallel to the optical axis of the lens 22.

Illustratively, the magnetic member and the conductive member are disposed opposite to each other in a direction parallel to the optical axis of the lens 22, such as the magnetic member is disposed on the bearing assembly 23, and the conductive member is disposed on the lens mount 21, wherein the lens mount 21 may be provided with a conductive mounting groove for mounting the conductive member, the conductive member is mounted on the conductive mounting groove, and the conductive member is capable of being engaged with the magnetic member in an energized state to enable the bearing assembly 23 to move in a direction parallel to the optical axis of the lens 22. It will be appreciated that the magnetic member and the conductive member are disposed opposite to each other in a direction parallel to the optical axis of the lens 22 (or Z direction), and based on the fleming's left hand rule, a magnetic field can be generated after the conductive member is energized, and the magnetic field generated by the conductive member can interact with the magnetic field of the magnetic member to generate a first acting force (or magnetic acting force) parallel to the optical axis of the lens 22, where the first acting force acts on the carrier 23 to drive the carrier 23 to move along the optical axis parallel to the lens 22, so as to drive the carrier 23 and the lens 22 to move together along the optical axis parallel to the lens 22.

Of course, in some embodiments, the magnetic element may be disposed on the lens holder 21, and the conductive element may be disposed on the carrier assembly 23, which is not limited herein.

It will be appreciated that other driving motors may be used for the lens driving mechanism for driving the lens 22, and the application is not limited thereto.

Specifically, the lens 22 may be made of glass or plastic. The lens 22 is mainly used to change the propagation path of light and focus the light. Lens 22 may include multiple sets of lenses that correct the filtered light for each other; when light passes through the lens 22, the multiple lens groups filter stray light (such as infrared light) layer by layer, so as to increase the imaging effect of the camera module 20.

The camera module is used as a module for capturing images, and further includes a photosensitive assembly 24, please refer to fig. 3 and fig. 4 in combination with fig. 2, fig. 3 is a first exploded view of the camera module provided in the embodiment of the present application, and fig. 4 is a second exploded view of the camera module provided in the embodiment of the present application. It can be appreciated that, in the optical axis direction of the lens 22 of the camera module 20, the photosensitive assembly 24 is disposed opposite to the lens 22, and the photosensitive assembly 24 can convert the acquired optical signal into an electrical signal.

It should be noted that, in order to meet the photographing requirement of people, some mobile terminals, such as mobile phone manufacturers, use an optical anti-shake (Optical Image Stabilization, OIS) motor built in the mobile phone to drive the camera module built in the mobile phone to move, so as to realize the anti-shake function of the built-in camera of the mobile phone. In the related art, some mobile terminals use OIS to drive a lens to move, so as to implement anti-shake of the lens. However, as the lens is heavier and heavier, the driving force required for moving the lens is larger and larger, the power consumption is greatly increased, and the better anti-shake effect cannot be achieved by driving the lens.

Based on this, the camera module 20 provided in the embodiment of the present application adopts a manner of driving the photosensitive assembly 24 to move for anti-shake, and it can be understood that referring to fig. 3, the camera module 20 further includes a driving mechanism 25, and the driving mechanism 25 is used for driving the photosensitive assembly 24 to move along a direction perpendicular to the optical axis of the lens 22, so as to implement anti-shake of the photosensitive assembly 24. It will be appreciated that the photosensitive assembly 24 is smaller in size and weight than the lens 22, and therefore, the power consumption required to move by driving the photosensitive assembly 24 is smaller than that required to move the lens 22, with higher reliability and better anti-shake effect.

It may be further appreciated that, based on the optical anti-shake technology, the sensor such as the gyroscope or the accelerometer of the electronic device 100 (or the camera module 20) may detect shake of the lens 22 to generate a shake signal, and transmit the shake signal to the electronic device 100 and/or the processing chip of the camera module 20, and the electronic device 100 and/or the processing chip of the camera module 20 may calculate the displacement amount of the driving mechanism 25 to be compensated, so that the driving mechanism 25 may compensate the photosensitive assembly 24 according to the shake direction of the photosensitive assembly 24 and the displacement amount thereof, thereby improving the imaging effect of the camera module 20 caused by shake generated in the use process of the user.

Referring to fig. 5 in combination with fig. 2 to fig. 4, fig. 5 is a cross-sectional view of a camera module according to an embodiment of the application. The camera module 20 further includes a housing 27, the housing 27 may be fixed below the lens base 21, the housing 27 is provided with a mounting cavity 271 and a light-passing hole 272 communicated with the mounting cavity 271, the photosensitive assembly 24 is movably disposed in the mounting cavity 272, and it can be understood that the photosensitive assembly 24 is disposed opposite to the light-passing hole 272, so that light can be incident on the photosensitive assembly 24 through the light-passing hole 272. The housing 27 serves to protect the photosensitive assembly 24 and to be connected to the lens mount 21.

It is understood that the photosensitive assembly 24 may include a photosensitive element 241 and a circuit board 242, where the photosensitive element 241 is electrically connected to the circuit board 242, and the photosensitive element 241 can convert the acquired optical signal into an electrical signal.

The photosensitive element 241 may be an image sensor such as a charge coupled device (Charge Coupled Device, abbreviated as CCD) or an image sensor such as a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, abbreviated as CMOS). Other types of image sensors than CMOS or CCD are also possible, such as CID sensors (ChargeInjection Device, charge injection devices). It will be appreciated that for CMOS, digital signal processing (Digital Signal Processing, DSP for short) may be integrated within the CMOS. CMOS has advantages of high integration level, low power consumption, low cost, etc., and is suitable for mobile devices such as mobile phones with limited installation space 211. The photosensitive element 241 may be disposed opposite to the lens 22 in the optical axis direction of the camera module 20 (i.e. the optical axis direction of the lens 22), and is mainly used for receiving light collected by the lens 22 and converting an optical signal into an electrical signal, so as to facilitate the imaging requirement of the camera module 20. The driving mechanism 25 is mainly used for improving the imaging effect of the camera module 20 due to the shake generated during the use process of the user, so that the imaging effect of the photosensitive assembly 24 can meet the use requirement of the user.

It is understood that the first frame 243 may serve to protect the photosensitive element 241.

In this embodiment, the camera module 20 may be used to implement functions of photographing, video recording, face recognition unlocking, code scanning payment, etc. of the electronic device 100. Note that, the camera module 20 may be a rear camera or a front camera, which is not limited in this embodiment.

The camera module 20 may further include a Filter 203, such as an infrared Filter (IR Filter), for filtering infrared light. It can be understood that the side of the circuit board 242 facing the lens 22 is connected with a first frame 243, the optical filter 203 is connected to the first frame 243, the optical filter 203 is located between the lens 22 and the photosensitive element 241, and the optical filter 203, the lens 22 and the photosensitive element 241 are coaxially arranged, so that the light can be filtered by the optical filter 203 and then irradiated to the photosensitive element 241 after passing through the lens 22. It can be understood that the lens 22, the optical filter 203 and the photosensitive element 241 are all coaxially disposed.

In order to facilitate the installation of the optical filter 203, as shown in fig. 5, the first frame 243 is provided with an installation groove 2432, the shape of the installation groove 2432 is adapted to the shape of the optical filter 203, and the optical filter 203 is installed in the installation groove 2432.

Please refer to fig. 6, fig. 6 is a cross-sectional view of a camera module of the prior art. In the related art, the camera module includes a housing 27a and a photosensitive assembly 24a, the housing 27a is covered on the photosensitive assembly 24a, the photosensitive assembly 24a includes a photosensitive element 241a and a circuit board 242a, and the photosensitive element 241a is disposed on the circuit board 242a. When the camera module drives the photosensitive assembly 24a to move through the driving mechanism to perform anti-shake, in order to ensure the normal movement of the photosensitive assembly 24a, a gap for the photosensitive assembly 24a to move is required between the circuit board 242a and the housing 27a in the Z-axis direction, but the gap easily causes the photosensitive assembly 24a to move unstably, so the ball 29a is disposed in the gap in the related art to fill the gap between the circuit board 242a and the housing 27 a. However, due to the influence of material tolerance, assembly tolerance and other factors, it is difficult to ensure that the balls 29a are in good contact with the circuit board 242a and the housing 27a in the anti-shake process, so that noise is easily generated due to collision between the balls 29a and the housing 27a or between the balls and the circuit board 242a, the risk of generating chips due to collision is greatly increased, the generated chips easily fall in an imaging area, and bad points are finally formed, so that bad experience is brought to users.

The elastic sheet 291 may be an integrally formed structure, and may be formed by plate blanking, stamping or etching, but is not limited to this forming method, and the elastic sheet 291 may be formed by other methods.
