[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] The embodiments of the present application provide a camera module and an electronic device, which can solve the problem that the filter is easy to break. This will be described below with reference to the accompanying drawings.

[0031] It is understood that the "electronic device" (or simply "terminal") used herein includes but is not limited to a device configured to receive / send communication signals via a wired connection and / or via a wireless communication network such as a cellular network, a wireless local area network, etc. Examples of mobile terminals include but are not limited to cellular phones and conventional laptop and / or palmtop receivers or other electronic devices including a radio telephone transceiver. A mobile phone is an electronic device configured with a cellular communication module.

[0032] Among them, see Figure 1 , Figure 1 The electronic device 100 provided in the embodiment of the present application can be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The following description will be made using a mobile phone as an example. Figure 1 As shown, the electronic device 100 may include a housing 10, a camera module 20 and a display screen 30. The display screen 30 is disposed on the housing 10 and can be used to display images. The camera module 20 can be disposed on the housing 10 and can receive light from the external environment to achieve image capture.

[0033] See also Figure 2 , Figure 2 An exploded view of a camera module provided in an embodiment of the present application. The camera module 20 may include a lens mount 21, a lens 22, a bearing assembly 23, and a lens driving mechanism (not shown). The bearing assembly 23 is disposed on the lens mount 21, and the lens 22 is disposed on the bearing assembly 23 and supported by the bearing assembly 23. Among them, the lens mount 21 is provided with an installation space 211, and the bearing assembly 23 and the lens driving mechanism are disposed in the installation space 211 of the lens mount 21, and the lens driving mechanism is used to drive the bearing assembly 23 to move in a direction parallel to the optical axis of the lens to achieve the focusing of the lens.

[0034] Exemplarily, the lens drive mechanism can adopt an electromagnetic motor, such as a voice coil motor. Exemplarily, the lens drive mechanism can include a magnetic part and a conductive part, one of which is arranged on the supporting component 23, and the other is arranged on the lens mount 21. When powered on, the conductive part can cooperate with the magnetic part to enable the supporting component 23 to move along a direction parallel to the optical axis of the lens 22, so as to drive the supporting component 23 and the lens 22 to move together along a direction parallel to the optical axis of the lens 22.

[0035] Exemplarily, the magnetic component and the conductive component are relatively arranged in a direction parallel to the optical axis of the lens 22, such as, the magnetic component is arranged on the bearing assembly 23, and the conductive component is arranged on the lens mount 21, wherein the lens mount 21 may be provided with a conductive mounting groove for mounting the conductive component, the conductive component is mounted in the conductive mounting groove, and the conductive component can cooperate with the magnetic component in the power-on state so that the bearing assembly 23 can move in a direction parallel to the optical axis of the lens 22. It can be understood that the magnetic component and the conductive component are relatively arranged in a direction parallel to the optical axis of the lens 22 (or the Z direction), and based on Fleming's left-hand rule, the conductive component can generate a magnetic field after being powered on, and the magnetic field generated by the conductive component can interact with the magnetic field of the magnetic component to generate a first force (or magnetic force) parallel to the optical axis of the lens 22, and the first force acts on the bearing assembly 23 to drive the bearing assembly 23 to move in a direction parallel to the optical axis of the lens 22, so as to drive the bearing assembly 23 and the lens 22 to move together in a direction parallel to the optical axis of the lens 22.

[0036] It can be understood that the direction of the first force can be changed by controlling the direction of the current in the conductive member.

[0037] Exemplarily, the conductive member may be a coil, which is electrically connected to a circuit board, and the control chip on the circuit board controls the on and off of the coil current to control whether the carrying component 23 moves.

[0038] Of course, in some embodiments, the magnetic component may be disposed on the lens holder 21 , and the conductive component may be disposed on the bearing assembly 23 , and the present application does not make any limitation thereto.

[0039] It is understandable that the lens driving mechanism for driving the lens 22 to move may also use motors with other driving modes, and the present application does not limit this.

[0040] Specifically, the material of the lens 22 can be glass or plastic. The lens 22 is mainly used to change the propagation path of light and focus the light. The lens 22 can include multiple sets of lenses, and the multiple sets of lenses will correct and filter the light mutually; when the light passes through the lens 22, the multiple sets of lenses filter stray light (such as infrared light) layer by layer, so as to increase the imaging effect of the camera module 20.

[0041] The camera module is used as a module for capturing images, and it also includes a photosensitive element 241. Figure 3 , Figure 3 This is a first cross-sectional view of the camera module provided in the embodiment of the present application. It can be understood that in the optical axis direction of the lens 22 of the camera module 20, the photosensitive element 241 is arranged opposite to the lens 22, and the photosensitive element 241 can convert the acquired light signal into an electrical signal.

[0042] It can be understood that the camera module also includes a circuit board 242, which is arranged on one side of the lens holder 21 in the optical axis direction of the lens 22, and 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 circuit board 242 can be, for example, a printed circuit board (PCB).

[0043] The photosensitive element 241 can specifically be an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). It can also be an image sensor of other types other than CMOS or CCD, such as a CID sensor (Charge Injection Device). It is understandable that for CMOS, digital signal processing (DSP) can be integrated into CMOS. CMOS has the advantages of high integration, low power consumption, and low cost, and is more suitable for mobile devices such as mobile phones with limited installation space. The photosensitive element 241 can be arranged opposite to the lens 22 in the optical axis direction of the camera module 20 (that is, the optical axis direction of the lens 22), and is mainly used to receive light collected from the lens 22 and convert the optical signal into an electrical signal, so as to realize the imaging requirements of the camera module 20.

[0044] To protect the photosensitive element 241, please refer to Figure 2 and Figure 3 The camera module further includes a first frame 25, which is disposed between the circuit board 242 and the lens holder 21. The first frame 25 is connected to the circuit board 242 and defines a receiving space 251 with the circuit board 242. The photosensitive element 241 is located in the receiving space 251. It can be understood that the first frame 25 can protect the photosensitive element 241.

[0045] It is also understandable that the first frame 25 is provided with an avoidance hole 252 , and the photosensitive element 241 is arranged opposite to the avoidance hole 252 , so that the light incident from the lens 22 can be incident on the photosensitive element 241 through the avoidance hole 252 .

[0046] In this embodiment, the camera module 20 can be used to realize functions such as taking pictures, recording, face recognition unlocking, and scanning code payment of the electronic device 100. In addition, it should be noted that the camera module 20 can be a rear camera or a front camera, which is not limited in this embodiment.

[0047] In order to filter infrared light, the camera module 20 may further include a filter 26, such as an infrared filter (IR Filter). Exemplarily, the filter 26 may be blue glass. It is understood that the filter 26 is located between the lens 22 and the photosensitive element 241, and the filter 26, the lens 22, and the photosensitive element 241 are coaxially arranged so that light can pass through the lens 22, be filtered by the filter 26, and then irradiate the photosensitive element 241. It is understood that the lens 22, the filter 26, and the photosensitive element 241 are always coaxially arranged.

[0048] In the related art, in order to install the filter, a mounting support is usually provided, and the filter is fixed on the mounting support by gluing. When the camera module falls, it will be subjected to a large impact force, and the impact force will act on the components in the camera module. For example, when the camera module falls, the mounting support in the camera module will be subjected to a large impact force. Since the filter is fixed on the support by gluing, when the mounting support is subjected to a large impact, the filter is easily debonded or broken.

[0049] Based on this, see Figure 3 and Figure 4 , Figure 4The connection structure diagram of the optical filter, the first frame and the suspension member provided in the embodiment of the present application. The optical filter 26 of the camera module 20 provided in the embodiment of the present application is arranged in the avoidance hole 252 of the first frame 25. It can be understood that the optical filter 26 does not contact the avoidance hole 252. The camera module 20 provided in the embodiment of the present application also includes an elastic suspension member 27, which is connected to the optical filter 26 and is used to make the optical filter 26 in a suspended state relative to the first frame 25.

[0050] In the embodiment of the present application, the filter 26 is suspended relative to the first frame 25 by connecting the suspension member 27 to the filter 26, that is, the suspension member 27 suspends the filter 26 so that the filter 26 can be spaced apart from the first frame 25. In this way, when the camera module 20 is impacted, the energy generated by the impact can be transferred to the suspension member 27, and the elastic suspension member 27 can be elastically deformed to play a buffering role, thereby absorbing the impact force, and the filter 26 is spaced apart from the first frame 25 or the filter 26 is kept suspended, thereby effectively avoiding the problem of deformation or breakage of the filter 26 due to the impact force. In addition, the filter 26 is suspended, which can also prevent the filter 26 from colliding with the first frame 25.

[0051] Among them, the stiffness of the suspension member 27 in the direction parallel to the optical axis of the lens 22 is greater than the stiffness of the suspension member 27 in the direction perpendicular to the optical axis of the lens 22. In this way, the filter 26 can be supported in the direction parallel to the optical axis of the lens 22, or the suspension member 27 can be suspended.

[0052] The material of the suspension member 27 can be copper alloy such as C1990 or BF158, which has the characteristics of good elasticity and high yield strength. It can not only ensure the suspension of the filter 26, but also ensure that the camera module 20 can undergo elastic deformation to play a buffering role when a collision occurs, thereby absorbing the impact force and keeping the filter 26 spaced from the first frame 25 or keeping the filter 26 suspended, thereby effectively avoiding the problem of deformation or breakage of the filter 26 due to impact force.

[0053] In order to more clearly illustrate the specific structure of the suspension member 27 and its related structures, this will be described below with reference to the accompanying drawings.

[0054] See also Figure 4The suspension member 27 includes a first connection portion 271, a second connection portion 272 and an elastic portion 273. The first connection portion 271 is connected to the first frame 25. The second connection portion 272 is connected to the filter 26. The elastic portion 273 is connected between the first connection portion 271 and the second connection portion 272. In this way, under the cooperation of the first connection portion 271, the second connection portion 272 and the elastic portion 273, the filter 26 can be suspended, that is, the filter 26 can be suspended so that the filter 26 can be spaced apart from the first frame 25. When the camera module 20 is impacted, the energy generated by the impact can be transferred to the elastic portion 273 of the suspension member 27. The elastic elastic portion 273 can be elastically deformed to play a buffering role, thereby absorbing the impact force, and the filter 26 is spaced apart from the first frame 25 or the filter 26 is kept suspended, so that the problem of deformation or rupture of the filter 26 due to the impact force can be effectively avoided. The filter 26 is suspended in the air, which can prevent the filter 26 from colliding with the first frame 25. Figure 3 , Figure 5 and Figure 6 , Figure 5 This is a second cross-sectional view of the camera module provided in an embodiment of the present application. Figure 6 This is a third cross-sectional view of the camera module provided in the embodiment of the present application. It can be understood that Figure 3 , Figure 5 and Figure 6 It is a structural schematic diagram of the filter 26 being in different states at different time periods when the camera module 20 is impacted.

[0055] It can be understood that the size of the avoidance hole 252 of the first frame 25 is larger than the size of the filter 26 , so that even if the camera module 20 is impacted, the filter 26 can maintain a distance from the first frame 25 under the suspension of the suspension member 27 .

[0056] It can be understood that the first connecting portion 271 of the hanging member 27 mainly serves to fix the hanging member 27. In some embodiments, please refer to Figure 7 , Figure 7 This is a fourth cross-sectional view of the camera module provided in the embodiment of the present application. The first connecting portion 271 can also be connected to the circuit board 242 .

[0057] Among them, the suspension member 27 can be an integrally formed structure, that is, the first connecting part 271, the elastic part 273 and the second connecting part 272 are integrally formed, and can be formed by plate punching, stamping or etching, but is not limited to this forming method. The suspension member 27 can also be formed by other methods.

[0058] In order to make the suspension member 27 have a better buffering and suspension effect, please refer to Figure 8 , Figure 8 A schematic diagram of a first partial structure of a suspension member provided in an embodiment of the present application. The elastic portion 273 of the suspension member 27 may include a first arm 2731 and a second arm 2732 that are bent and connected, the first arm 2731 being connected to the first connecting portion 271, and the second arm 2732 being connected to the second connecting portion 272. The first arm 2731 and the second arm 2732 are both elastic structures, and when the camera module 20 collides, the bending connection between the first arm 2731 and the second arm 2732 may be deformed, and the bending connection between the first arm 2731 and the second arm 2732 may restore the deformation, which may drive the filter 26 to quickly reset. The first arm 2731 and the second arm 2732 are arranged in a bent connection, which may increase the elasticity of the elastic portion 273, which may provide better buffering on the one hand, and have a better reset function on the other hand.

[0059] Among them, Figure 3 As shown, the bending direction of the first arm 2731 and the second arm 2732 can be perpendicular to the optical axis direction of the lens 22. Of course, in some embodiments, not shown, the bending direction of the first arm 2731 and the second arm 2732 can also be parallel to the optical axis direction of the lens 22.

[0060] It can be understood that the first arm 2731 and the second arm 2732 can be straight arms or bent arms. Fig. 9 , Fig. 9 A schematic diagram of a second partial structure of a suspension member provided in an embodiment of the present application. The first arm 2731 may include a first arm 27311 and a second arm 27312 that are connected in a bent manner, and the second arm 2732 may include a third arm 27321 and a fourth arm 27322 that are connected in a bent manner. Among them, the end of the first arm 27311 away from the second arm 27312 is connected to the first connecting portion 271, the second arm 27312 is connected to the third arm 27321 in a bent manner, and the fourth arm 27322 is connected to the second connecting portion 272. That is, the elastic portion 273 can be bent multiple times to form multiple bent portions.

[0061] Of course, one of the first arm 2731 and the second arm 2732 may be a straight arm and the other may be a bent arm. For example, the first arm 2731 is a straight arm, the second arm 2732 is a bent arm, and the second arm 2732 may include a third arm 27321 and a fourth arm 27322 connected in a bent manner. Alternatively, the first arm 2731 is a bent arm, the first arm 2731 may include a first arm 27311 and a second arm 27312 connected in a bent manner, and the second arm 2732 is a straight arm.

[0062] See also Fig.10 Combined with Figure 4 , Fig.10A schematic diagram of the structure of the first frame provided in an embodiment of the present application. In order to better fix the suspension member 27, when the first connection portion 271 is connected to the first frame 25, the first frame 25 includes a first mounting plane 253 arranged opposite to the first connection portion 271, and the first connection portion 271 is attached to the first mounting plane 253. In this way, by attaching the entire first connection portion 271 to the first mounting plane 253 of the first frame 25, the connection area between the first connection portion 271 and the first mounting plane 253 can be increased as much as possible, so as to effectively increase the connection stability between the first connection portion 271 and the first frame 25, so that the suspension member 27 can be better fixed.

[0063] The first connection portion 271 may be fixedly connected to the first installation plane 253 of the first frame 25 by welding or gluing.

[0064] Of course, in some embodiments, the first connection part 271 can also be fixedly connected to the first frame 25 by means of fastening. Exemplarily, the first connection part 271 is provided with a first connection hole, the first frame 25 is provided with a second connection hole, and the first fastener is passed through the first connection hole and the second connection hole to lock the first connection part 271 to the first mounting plane 253 of the first frame 25. For example, the first fastener can be a screw, and the first connection hole and the second connection hole can be threaded holes. By means of threaded connection between the screw and the threaded hole, the first connection part 271 is locked to the first mounting plane 253 of the first frame 25.

[0065] Alternatively, in some embodiments, see Figure 7 When the first connection part 271 is connected to the circuit board 242, the circuit board 242 includes a second mounting plane 2421 arranged opposite to the first connection part 271, and the first connection part 271 is attached to the second mounting plane 2421. In this way, by attaching the entire first connection part 271 to the second mounting plane 2421 of the circuit board 242, the connection area between the first connection part 271 and the second mounting plane 2421 can be increased as much as possible, so as to effectively increase the connection stability between the first connection part 271 and the circuit board 242, so that the suspension member 27 can be better fixed.

[0066] The first connection portion 271 may be fixedly connected to the second mounting plane 2421 of the circuit board 242 by welding or gluing.

[0067] Of course, in some embodiments, the first connection part 271 can also be fixedly connected to the circuit board 242 by means of fastener locking. Exemplarily, the first connection part 271 is provided with a third connection hole, the circuit board 242 is provided with a fourth connection hole, and the second fastener is passed through the third connection hole and the fourth connection hole to lock the first connection part 271 to the second mounting plane 2421 of the circuit board 242. For example, the second fastener can be a screw, and the third connection hole and the fourth connection hole can be threaded holes. By means of threaded connection between the screw and the threaded hole, the first connection part 271 is locked to the second mounting plane 2421 of the circuit board 242.

[0068] In order to better connect the suspension member 27 with the filter 26, please refer to Fig.11 Combined with Figure 4 , Fig.11 A schematic diagram of the structure of the optical filter provided in an embodiment of the present application. The optical filter 26 includes a third mounting plane 261 arranged opposite to the second connecting portion 272, and the second connecting portion 272 is attached to the third mounting plane 261. In this way, by attaching the entire second connecting portion 272 to the third mounting plane 261 of the optical filter 26, the connection area between the second connecting portion 272 and the third mounting plane 261 can be increased as much as possible, so as to effectively increase the connection stability between the second connecting portion 272 and the optical filter 26, so that the suspension member 27 can be better connected to the optical filter 26.

[0069] The second connection portion 272 can be attached to the third mounting plane 261 by means of an adhesive layer. In this way, by means of gluing, it is not necessary to perform extra processing on the filter 26, thereby ensuring the integrity of the filter 26 and preventing damage to the filter 26 caused by excessive processing operations.

[0070] See also Fig.12 Combined with Fig.11 , Fig.12 A schematic diagram of the structure of the suspension member provided in the embodiment of the present application. The filter 26 may be a rectangular parallelepiped structure. In order to enable the suspension member 27 to better suspend the filter 26, the suspension member 27 may be designed to match the shape of the filter 26. Exemplarily, the second connecting portion 272 may include a first side 2721, a second side 2722, a third side 2723 and a fourth side 2724, the first side 2721 and the second side 2722 are arranged opposite to each other, and the third side 2723 and the fourth side 2724 are arranged opposite to each other.

[0071] The first side 2721 is connected between the third side 2723 and the fourth side 2724 , so that the connection between the first side 2721 and the third side 2723 forms a first corner portion 2725 , and the connection between the first side 2721 and the fourth side 2724 forms a second corner portion 2726 .

[0072] The second side 2722 is connected between the third side 2723 and the fourth side 2724, so that the connection between the second side 2722 and the third side 2723 forms a third corner portion 2727, and the connection between the second side 2722 and the fourth side 2724 forms a fourth corner portion 2728. In this way, by setting the second connecting portion 272 to have a structure with the first side 2721, the second side 2722, the third side 2723 and the fourth side 2724, the shape of the filter 26 can be better matched, so that the second connecting portion 272 can be better connected to the filter 26, and the connection stability is better.

[0073] Among them, in order to enable the suspension member 27 to better suspend the filter 26, the elastic part 273 may include a first elastic sub-part 273a, a second elastic sub-part 273b, a third elastic sub-part 273c and a fourth elastic sub-part 273d, and the first connecting part 271 includes a first connecting sub-part 271a, a second connecting sub-part 271b, a third connecting sub-part 271c and a fourth connecting sub-part 271d.
