[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] It should be understood that in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0049] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0050] A Hall device is a solid-state electronic device that utilizes the Hall effect. It uses a magnetic field as a working medium and converts the motion parameters of an object into a digital voltage output, giving it sensing and switching functions.

[0051] Focal length is also called focal length. It is a measure of the convergence or divergence of light in an optical system. It refers to the distance from the center of the lens to the focus of light. Focusing is also called focusing. The process of changing the distance and position of the object through the camera focusing mechanism to make the image of the object clear is focusing.

[0052] In the camera modules of electronic devices such as mobile phones, in order to make the image of the object being photographed clear, it is necessary to adjust the distance between the lens and the photosensitive element. However, the camera module cannot be adjusted manually like a digital camera, and can only be automatically adjusted through structures such as voice coil motors. In order to achieve a closed loop for the diagonal of the camera module, a Hall device is usually used to measure the change in the magnetic induction intensity of the moving parts to detect the change in the position of the camera module lens, thereby completing the closed-loop focusing function.

[0053] However, since Hall magnets need to be arranged at corresponding positions when the Hall device is working, this will lead to an increase in the number of magnets in the camera module. In multi-camera scenarios, the magnetic interference problem of adjacent camera modules needs to be considered. The existence of Hall magnets is not conducive to solving the magnetic interference problem, and limits the design freedom of electronic equipment in multi-camera scenarios.

[0054] Therefore, the present application provides a camera module that reduces the number of magnets in the camera module, so that non-magnetic areas are formed on both sides of the camera module, which is conducive to enriching the arrangement and combination methods of adjacent camera modules in multi-camera scenarios and improving the design freedom of electronic devices in multi-camera scenarios.

[0055] The electronic device in the embodiment of the present application may be a mobile phone, a tablet computer, a laptop computer, a smart bracelet, a smart watch, a smart helmet, smart glasses, etc. The electronic device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, an electronic device in a 5G network, or an electronic device in a future Public Land Mobile Network (PLMN), etc., and the embodiment of the present application does not limit this.

[0056] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0057] Combination Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a camera module. In some embodiments, the camera module includes: an actuator 1, an optical lens 2 and a photosensitive component 3.

[0058] The actuator 1 includes a mover portion 11 , a stator portion 12 and a detection assembly 13 .

[0059] The optical lens 2 is connected to the movable part 11, the photosensitive component 3 is connected to the stator part 12, and the movable part 11 and the stator part 12 are movably connected along the light path of the optical lens 2; the movable part 11 includes two driving coils 111, and the two driving coils 111 are arranged along the first direction B; the stator part 12 includes two magnet assemblies 121, and the two magnet assemblies 121 are arranged along the first direction B, and each magnet assembly 121 corresponds to the position of a driving coil 111.

[0060] The detection component 13 includes at least one moving pole piece 131 and at least one fixed pole piece 132, at least one moving pole piece 131 is located on the side of the moving part 11 along the second direction C, at least one fixed pole piece 132 is located on the side of the stator part 12 along the second direction C, and the position of at least one moving pole piece 131 and the position of at least one fixed pole piece 132 are spaced relative to each other.

[0061] The first direction B and the second direction C are perpendicular to each other, and the first direction B and the second direction C are perpendicular to the light path respectively.

[0062] The camera module of this embodiment includes an actuator 1, an optical lens 2 and a photosensitive component 3. The optical lens 2 is connected to the movable part 11 of the actuator 1 and can move along the light path with the movable part 11 to achieve zooming of the camera module; the photosensitive component 3 is connected to the stator part 12 to receive the light entering through the optical lens 2 to perform an imaging task; the detection component 13 includes a moving pole piece 131 and a fixed pole piece 132 arranged relatively at intervals, and the moving pole piece 131 can move with the movable part 11 and the optical lens 2, thereby changing the relative position between the moving pole piece 131 and the fixed pole piece 132. The change in the relative position will cause the change in the facing area between the moving pole piece 131 and the fixed pole piece 132. The change in the facing area will cause the capacitance value between the moving pole piece 131 and the fixed pole piece 132 to change. By measuring the capacitance value between the moving pole piece 131 and the fixed pole piece 132, the position of the moving pole piece 131, the movable part and the optical lens 2 can be determined, thereby achieving closed-loop focusing of the camera module.

[0063] The detection component 13 has a simple structure and does not require magnetic parts, which reduces the number of magnets in the camera module and forms non-magnetic areas on both sides of the camera module. This is conducive to enriching the arrangement and combination of adjacent camera modules in multi-camera scenarios and improving the design freedom of electronic equipment in multi-camera scenarios.

[0064] Compared with the Hall device in the related art, the detection component 13 of this embodiment does not need to be arranged with a Hall magnet, which can reduce the number of magnets in the camera module and reduce the magnetic interference in the camera module in a multi-camera scenario.

[0065] In a multi-camera scenario, electronic devices need to place the camera modules on the non-magnetic side of the adjacent camera modules to avoid magnetic interference from adjacent camera modules. However, camera modules using Hall devices usually have only one non-magnetic side, which reduces the number of possible permutations of adjacent camera modules.

[0066] The camera module of this embodiment has drive coils 111 or magnet assemblies 121 arranged on both sides along the first direction B, and no magnets or coils on both sides along the second direction C, so that the camera module has two non-magnetic sides. In a multi-camera scenario, the camera module can utilize adjacent camera modules arranged on both sides along the second direction C, thereby enriching the number of permutations and combinations of adjacent camera modules and improving the design freedom of electronic equipment in multi-camera scenarios.

[0067] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the axis of the driving coil 111 is arranged along the first direction B, so that the driving coil 111 can generate a coil magnetic field extending along the first direction B, and the coil magnetic field interacts with the magnet magnetic field generated by the magnet assembly 121 also arranged in the first direction B, thereby generating a force that drives the movable part 11 to move along the light path.

[0068] Combination Figure 4 and Figure 5 As shown, in some embodiments, the magnet assembly 121 includes at least two magnet bodies 1211, and at least two magnet bodies 1211 are arranged along the direction of the light path; the magnetic poles of the magnet bodies 1211 are arranged along the first direction B, and the magnetic poles of at least one magnet body 1211 are opposite to the magnetic poles of other magnet bodies 1211.

[0069] Through the above arrangement, the magnet assembly 121 can form at least two magnetic fields in opposite directions on the light path. When the coil magnetic field generated by the driving coil 111 interacts with at least two magnetic fields, it can generate a mutually repulsive force with the same-sex magnetic field and a mutually attractive force with the opposite-sex magnetic field. By changing the current direction or current value in the driving coil 111, the interaction force between the driving coil 111 and different magnet assemblies 121 can be adjusted, thereby achieving the relative position adjustment of the mover part 11 and the stator part 12.

[0070] Combination Figure 4 and Figure 5 As shown, in some embodiments, the mover part 11 further includes a carrier member 112 , and the two driving coils 111 are located on two outer side surfaces of the carrier member 112 along the first direction B.

[0071] The stator part 12 further includes a housing member 122 . The carrier member 112 is located inside the housing member 122 . The two magnet assemblies 121 are respectively located on two inner side surfaces of the housing member 122 along the first direction B, and each magnet assembly 121 corresponds to a driving coil 111 .

[0072] The movable part 11 of the present embodiment includes a carrier part 112 and a driving coil 111, wherein the optical lens 2 is installed in the mounting hole 1121 of the carrier part 112, and the driving coil 111 is wound around the circumferential outer side of the carrier part 112. After the driving coil 111 is energized, it can generate a magnetic force with the magnetic structure of the stator part 12, thereby pushing the carrier part 112 to move along the light input path A. The carrier part 112 drives the optical lens 2 to move closer to or away from the photosensitive component 3 along the direction of the light input path A, thereby realizing the focal length adjustment of the camera module.

[0073] In some possible implementations, a mounting hole 1121 for connecting the optical lens 2 is provided in the middle of the carrier member 112, and an avoidance hole 1221 for avoiding the optical lens 2 is provided in the middle of the shell member 122, the axis of the mounting hole 1121 coincides with the light input path A, the mounting hole 1121 of the carrier member 112 coincides with the axis of the avoidance hole 1221 of the shell member 122, and the top of the optical lens 2 extends to the outside of the stator part 12 through the avoidance hole 1221.

[0074] In some possible implementations, a winding portion 1122 is provided on the outer side of the carrier member 112 along the first direction B, and the driving coil 111 is wound around the winding portion 1122 , thereby achieving a reliable connection between the driving coil 111 and the carrier member 112 .

[0075] Combination Figure 4 and Figure 5 As shown, in some embodiments, at least one moving pole piece 131 is located on the outer side surface of the carrier member 112 along the second direction C, and at least one fixed pole piece 132 is located on the inner side surface of the shell member 122 along the second direction C, and the position of at least one moving pole piece 131 and the position of at least one fixed pole piece 132 are spaced relative to each other.

[0076] The moving pole piece 131 of this embodiment is located on the outer side of the carrier 112, opposite to the fixed pole piece 132 of the stator part 12, and the moving pole piece 131 moves with the carrier 112, changing the facing area between the moving pole piece 131 and the fixed pole piece 132. There is a linear relationship between the facing area and the capacitance value, so that the relative position of the stator part 12 and the moving part 11 in the direction of the light path can be determined, thereby realizing the closed-loop focus of the camera module.

[0077] Combination Figure 4 , 5 As shown, in some possible implementations, there are two fixed pole pieces 132 , which are spaced apart on the inner side surface of the shell 122 along the direction of the light path A, and there is only one moving pole piece 131 .

[0078] Through the above arrangement, the two fixed pole pieces 132 are arranged at intervals on the inner side surface of the shell 122 along the direction of the light input path A. When the moving pole piece 131 moves along the direction of the light input path A, different parts of the moving pole piece 131 can respectively form two capacitor structures with the two fixed pole pieces 132. The detection unit 133 respectively detects the capacitance values ​​of the two capacitor structures, and can more accurately determine the relative position of the moving pole piece 131 and the fixed pole piece 132, thereby improving the position accuracy of the optical lens 2 and improving the focusing accuracy of the camera module.

[0079] Combination Figure 6As shown, in some embodiments, the detection component 13 also includes a detection unit 133, which is electrically connected to at least one moving pole piece 131 and at least one fixed pole piece 132 respectively; the detection unit 133 is used to detect the change in capacitance between at least one moving pole piece 131 and at least one fixed pole piece 132, and determine the relative position of the mover part 11 and the stator part 12 according to the change in capacitance.

[0080] According to the determining formula of the capacitor device: C=εS / 4πkd (C is the capacitance value, ε is a constant, S is the facing area of ​​the capacitor plates, d is the distance between the capacitor plates, and k is the electrostatic force constant), when the distance d between the capacitor plates is a constant, the capacitance value of the capacitor is only proportional to the facing area S. Therefore, the position change of the movable part 11 can be detected by the change in the capacitance value of the capacitor caused by the change in the facing area.

[0081] In this embodiment, the moving pole piece 131 only moves along the light path with the moving part 11, and the distance between the moving pole piece 131 and the fixed pole piece 132 is a constant value, but the facing area of ​​the moving pole piece 131 and the fixed pole piece 132 will change with the activity degree of the moving part 11, and according to the determination formula of the capacitor device, it can be known that the facing area and the capacitance value are in a linear relationship. The detection unit 133 is electrically connected to the moving pole piece 131 and the fixed pole piece 132 respectively. After detecting the capacitance value between the moving pole piece 131 and the fixed pole piece 132, the facing area between the moving pole piece 131 and the fixed pole piece 132 can be determined according to the capacitance value. Because the areas of the moving pole piece 131 and the fixed pole piece 132 are regular shapes (for example, squares, rectangles, etc.), the relative positions of the moving pole piece 131 and the fixed pole piece 132 in the direction of the light path can be easily calculated, so that the relative positions of the stator part 12 and the moving part 11 in the direction of the light path can be determined, thereby realizing the closed-loop focus of the camera module.

[0082] In some possible implementations, the detection unit 133 is integrated into an integrated circuit, which is electrically connected to the moving pole piece 131 and the fixed pole piece 132 respectively, applies a voltage between the moving pole piece 131 and the fixed pole piece 132, and determines the capacitance value between the moving pole piece 131 and the fixed pole piece 132 according to the change of the voltage.

[0083] Combination Figure 4 and Figure 5 As shown, in some embodiments, the actuator 1 further includes at least one elastic member 14 , the at least one elastic member 14 is located at one end of the mover portion 11 along the light path, and the at least one elastic member 14 is connected between the mover portion 11 and the stator portion 12 .

[0084] Optionally, the elastic member 14 includes an upper elastic sheet 141 and a lower elastic sheet 142 , the upper elastic sheet 141 is connected between the upper end of the carrier member 112 and the upper end of the shell member 122 , and the lower elastic sheet 142 is connected between the lower end of the carrier member 112 and the lower end of the shell member 122 .

[0085] Through the above arrangement, the mover part 11 is elastically and movably connected to the stator part 12 through the upper spring plate 141 and the lower spring plate 142. When the driving coil 111 is energized, the driving coil 111 will generate a coil magnetic field, and the coil magnetic field and the magnetic magnetic field generated by the magnet assembly 121 interact with each other. The driving coil 111 will move along the light input path A, and the optical lens 2 installed on the carrier 112 will move together. When the driving coil 111 is de-energized, the mover part 11 returns under the elastic force of the upper spring plate 141 and the lower spring plate 142, thereby realizing the autofocus function of the camera module.

[0086] Combination Figure 2 As shown, in some embodiments, the photosensitive component 3 includes a circuit board 31 and a photosensitive element 32 , the photosensitive element 32 is electrically connected to the circuit board 31 , and the optical lens 2 is located on the photosensitive path of the photosensitive element 32 .

[0087] The camera module of this embodiment is used to capture images or videos.

[0088] In some possible implementations, the photosensitive element 32 is also called an image sensor, which may be a complementary metal oxide semiconductor (CMOS) or a charge coupled device (CCD). It may also be other types of image sensors other than CMOS or CCD, such as a charge injection device (CID).

[0089] It is understandable that for CMOS, a digital signal processor (DSP) can be integrated into CMOS. CMOS has the advantages of high integration, low power consumption, and low cost, and is more suitable for electronic devices with limited installation space, such as mobile phones.

[0090] In some possible implementations, a printed circuit is provided on the surface of the circuit board 31, and the circuit board 31 includes a printed circuit board 31 (Printed Circuit Board, PCB), a flexible printed circuit board (Flexible Printed Circuit Board, FPC), a soft-rigid combination board, etc.

[0091] In some possible implementations, the camera module may further include a flash. The flash may be a single-color temperature flash or a dual-color temperature flash. The dual-color temperature flash refers to a combination of a warm light flash and a cold light flash, which may be used for light compensation at different color temperatures.

[0092] In some embodiments, the camera module includes a front camera and a rear camera. Typically, the front camera is disposed on the front panel of the electronic device, and the rear camera is disposed on the back of the electronic device. Exemplarily, there are at least two rear cameras, which are any one of a main camera, a depth of field camera, a wide-angle camera, and a telephoto camera, so as to realize the fusion of the main camera and the depth of field camera to realize the background blur function, the fusion of the main camera and the wide-angle camera to realize the panoramic shooting and the virtual reality (VR) shooting function or other fusion shooting functions.

[0093] Combination Figure 2 As shown, in some embodiments, the actuator 1 further includes a base portion 15, which is connected to the stator portion 12. The base portion 15 is connected to the lower end of the housing member 122 of the stator portion 12, wrapping the mover portion 11 therein, thereby achieving the integration of the actuator 1.

[0094] The two sides of the camera module of this embodiment along the second direction are formed as two non-magnetic sides. When other camera modules are arranged on the two non-magnetic sides, magnetic interference will not occur between the two camera modules. Figure 7 As shown, the camera module of this embodiment can utilize two non-magnetic sides to make any combination with the magnetic side or non-magnetic side of other camera modules, with richer arrangement and combination methods, which can improve the design freedom of electronic devices in multi-camera scenarios.

[0095] On the other hand, this embodiment provides an electronic device, which includes at least one camera module of the present application.

[0096] The electronic device of this embodiment adopts the camera module of the present application and has all the beneficial technical effects of all the embodiments in this document.

[0097] In some possible implementations, the electronic device includes a mainboard.

[0098] In the camera module provided in this embodiment, during the shooting process, the imaging light of the object enters the optical lens and then reaches the photosensitive element 32. The photons in the imaging light hit the image sensor to generate movable charges. This is the internal photoelectric effect. The movable charges gather to form an electrical signal.

[0099] The electrical signal is transmitted to the main board through a flexible circuit board or the like. The main board is provided with an analog-to-digital converter (A / D converter) and a digital signal processor (DSP). The A / D converter converts the electrical signal into a digital signal, which is processed by the DSP and finally transmitted to the screen of the electronic device to display the image, thus realizing the shooting of the object.
