Description

Technical Field

[0001] This application belongs to the field of camera equipment technology, and in particular relates to a camera module. Background Technology

[0002] Autofocus (AF) photography, while maintaining a constant focal length, uses a drive motor to change the image distance, thus achieving a sharp image of the subject. The lens's autofocus function relies on a drive motor, which consists of a coil and a magnetic component. The principle of lens autofocus is based on Faraday's law: when an energized coil interacts with a magnetic component, changing the magnitude of the current in the coil alters the magnitude of the generated electromagnetic force, thereby causing the motor to move the lens.

[0003] In related technologies, the lens assembly support component includes at least a retaining spring, a T-Holder (intermediate shell), and an outer shell. The lens assembly is housed within the retaining spring, and then the lens assembly and retaining spring are integrally mounted inside the intermediate shell and fixedly connected to the intermediate shell by adhesive application. The outer shell is fitted over the outside of the intermediate shell. Furthermore, the flexible circuit board (FPC) is zig-bent to release the rebound stress of the FPC. Correspondingly, the volume of the outer shell needs to be increased to accommodate the bent FPC, further increasing the size of the entire support component and camera module. It is evident that the camera module of the related technology, due to the above structure, has a relatively large overall size, failing to meet the requirements for simplified structure and reduced overall size of camera equipment.

[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] Autofocus photography, while maintaining a constant focal length, uses a drive motor to change the image distance, thus achieving a sharp image of the object. The autofocus function of a lens relies on a drive motor, which consists of a coil and a magnetic component. The principle of lens autofocus is based on Faraday's law: when an energized coil interacts with a magnetic component, changing the magnitude of the current in the coil alters the magnitude of the electromagnetic force generated, thereby driving the lens movement.

[0033] Figure 1 This is a schematic 3D diagram of a camera module provided by related technologies; Figure 2 This is a schematic exploded view of a camera module provided by related technologies; Figure 3 This is a schematic exploded view of the support components of the camera module provided by related technologies.

[0034] like Figures 1-3 As shown, the camera module of the related technology mainly consists of a support component a and a lens component b. The support component a includes a top-case a1, a retaining spring a2, a T-Holder a3, an outer shell a4, and a bottom-case a5.

[0035] Figures 1-3The shown gripping spring a2 includes four claws. One pair of opposing claws of the gripping spring a2 inserts into the limiting groove a31 of the intermediate shell a3, and another pair of opposing claws inserts into the limiting groove a41 of the outer shell a4. This allows the intermediate shell a3 to be suspended using the gripping spring a2. Then, the lens assembly b is attached using adhesive (such as...). Figure 1 c) is fixedly connected to the intermediate shell a3, thus suspending the lens assembly b. Each of the four claws of the grasping spring a2 is equipped with a ball bearing, which serves as a rotation point. The movement of the lens assembly b within the outer shell a4 is achieved by the rolling of the ball bearing within the limiting grooves a31 and a41.

[0036] like Figure 1 and Figure 2 As shown, in related technologies, the camera module releases the rebound stress of the FPC by bending it in a Z-shape. Correspondingly, the volume of the housing a4 needs to be increased to accommodate the bent FPC, which further increases the size of the entire support assembly and the camera module.

[0037] Due to the aforementioned structure, the camera modules of related technologies are relatively large in size, which cannot meet the requirements of simplifying the structure and reducing the size of camera equipment.

[0038] In view of the above problems, this application provides a camera module that can reduce the size of the support component, thereby reducing the size of the camera module, and meeting the need for simplified structure and reduced overall size of camera equipment.

Figure 5 A schematic exploded view of the supporting components provided for the implementation of this application. Figure 6 A schematic perspective view of the installation of the first support frame and lens assembly provided for the implementation of this application. Figure 7 A schematic diagram showing the positional relationship between the magnetic component and the coil assembly provided for the implementation of this application.

[0040] like Figure 6 As shown, the camera module includes a support assembly 10, a lens assembly 300, and a first rigid-flex board 600. The support assembly 10 is disposed on the lens assembly 300 to support the lens assembly 300. The lens assembly 300 is disposed on the first rigid-flex board 600. The first rigid-flex board 600 includes a first rigid board, a first flexible circuit board, and a second rigid board that are sequentially connected and electrically conductive. The first rigid board is disposed at the bottom of the lens assembly 300. The two ends of the first flexible circuit board are respectively connected to the first rigid board and the second rigid board. The first flexible circuit board is elastic. The second rigid board is electrically connected to an external motherboard through a first connector (not shown in the figure). Figure 6 and Figure 12As shown, the first flexible circuit board in this embodiment of the application is shaped like a long, suspended wire. It can be understood that the first flexible circuit board includes a plurality of long, suspended wires, which do not interfere with each other. Figure 12 This is a longitudinal cross-sectional view of the first flexible circuit board provided for implementation of this application. In this embodiment, based on the longitudinal cross-section of the first flexible circuit board, the first flexible circuit board includes a first insulating layer, a first metal layer, a second insulating layer, and a second metal layer stacked sequentially. The second metal layer is configured to support the first insulating layer, the second insulating layer, and the first metal layer. The first metal layer is a circuit layer and is conductive. In this embodiment, the second metal layer 806 can be a titanium-copper suspension wire, serving as a supporting metal layer. The first metal layer 804 can be copper circuitry, serving as a circuit layer. The materials of the first insulating layer 803 and the second insulating layer 805 can be insulating materials, such as PI (photosensitive polyimide), or epoxy resin, BT resin, etc. The first insulating layer 803 can isolate the first metal layer 804 from external conductors, and the second insulating layer 805 can insulate and block the first metal layer 804 and the second metal layer 806.

[0041] In this embodiment, the first flexible circuit board is shaped like a long, suspended wire instead of a Z-shaped FPC. This eliminates the need for the second support frame 200 to provide additional space to accommodate the Z-shaped FPC, thereby reducing the size of the second support frame 200 and the overall size of the support assembly and camera module. Furthermore, in related technologies, Z-shaped bending of the FPC results in significant reaction forces when the lens assembly moves, and the consistency after bending is difficult to guarantee. Consequently, the lens assembly is prone to tilting during movement, which in turn affects the production yield of the camera module.

[0042] In some implementations, such as Figures 4-7 As shown, the support assembly 10 in this embodiment includes a first support frame 100 and a second support frame 200. The first support frame 100 has an elastic support portion 101 and a fixing portion 102. The fixing portion 102 is used to fix the lens assembly 300, and the elastic support portion 101 is used to realize the movement of the lens assembly 300 within the first support frame 100. Figure 4 The fixing part 102 shown is connected to the first support frame 100. That is to say, in Figure 4 In the example, the fixing part 102 is a structure provided on the first support frame 100.

[0043] It should be noted that the first support frame 100 also includes a support frame body 103, with elastic support parts 101 and fixing parts 102 connected to the support frame body 103. The first support frame 100 may include two elastic support parts 101 and two fixing parts 102, or it may include three elastic support parts 101 and three fixing parts 102. The number of elastic support parts 101 and fixing parts 102 is not limited in this application. The support frame body 103 may be a spring.

[0044] like Figure 7 As shown, the lens assembly 300 is provided with a magnetic component 301.

[0045] The second support frame 200 is sleeved on the outside of the first support frame 100, and the first support frame 100 is connected to the second support frame 200 through the elastic support part 101.

[0046] Specifically, the fixing part 102 of the first support frame 100 is connected to the lens assembly 300. The fixing part 102 can be an integral structure with the first support frame 100, and then the fixing part 102 is connected to the lens assembly 300 by dispensing glue or welding. Figure 6 The welding point d shown.

[0047] Then the elastic support portion 101 of the first support frame 100 is connected to the second support frame 200. Specifically, a first receiving groove 202 can be provided on the inner side wall of the second support frame (the first receiving groove 202 is provided at each of the four corners), and the four elastic support portions 101 are respectively inserted into the four first receiving grooves 202.

[0048] This allows for the suspension of the first support frame 100. Since the connection between the first support frame 100 and the lens assembly 300 is established through the fixing part 102, the lens assembly 300 can also be suspended. A ball bearing 1023 is provided on the elastic support part 101, serving as a rotation point. The movement of the lens assembly 300 within the second support frame 200 is achieved by the rolling of the ball bearing 1023 within the first receiving groove 202.

[0049] A coil assembly 201 is mounted on the second support frame 200, positioned opposite to the magnetic component 301. Here, "opposite" refers to the relative positions of the magnetic component 301 and the coil assembly 201. This could mean the center of the magnetic component 301 is positioned opposite the center of the coil assembly 201. When energized, the coil assembly 201 generates a magnetic field, which interacts with the magnetic component 301, causing the lens assembly 300 to move.

[0050] The magnetic component 301 can specifically be a magnet. The coil assembly 201 can be an FPC-Coil (Flexible Printed Circuit Coil) to further save space and reduce size.

[0051] Since the first support frame 100 has both an elastic support portion 101 and a fixing portion 102, and the fixing portion 102 can fix the lens assembly 300, an intermediate shell is not needed to fix the lens assembly 300. Furthermore, the magnetic component 301 is directly disposed on the lens assembly 300. Therefore, the size of the support assembly 10 can be significantly reduced, thereby reducing the overall size of the camera module, thus meeting the requirement of simplified structure and reduced overall size of the camera device. In this embodiment, the overall size of the support assembly can be reduced by at least 0.5 mm on one side.

[0052] In some implementations, such as Figure 5 As shown, the first support frame 100 may have four elastic support portions 101 arranged in an array around the central axis of the first support frame 100, and the first support frame 100 may have four fixing portions 102 arranged in an array around the central axis of the first support frame 100. The elastic support portions 101 and the fixing portions 102 are staggered on the support frame body 103 of the first support frame 100.

[0053] The four elastic support parts 101 provide sufficient elasticity for the lens assembly 300 in the front-to-back, left-to-right, and up-down directions. The four fixing parts 102 can firmly fix the lens assembly 300. Furthermore, the four elastic support parts 101 and the four fixing parts 102 are staggered on the support frame body 103, thus better realizing the functions of fixing and elastic movement of the lens assembly 300.

[0054] like Figure 6 As shown, the four fixing parts 102 are fixedly connected to the lens assembly 300 by welding. Specifically, the four fixing parts 102 are fixedly connected to the housing of the lens assembly 300 by welding. The welding points of the four fixing parts 102 to the housing of the lens assembly 300 are as follows: Figure 6 As shown in d.

[0055] Figure 8 A schematic top view of the camera module provided in an embodiment of this application. Figure 9 for Figure 8 B-B sectional view. Figure 10 This is a schematic exploded view of another support component for the camera module provided in the embodiments of this application.

[0056] like Figure 8-10As shown, the fixing part 102 is connected to the lens assembly 300. The fixing part 102 includes two welded parts 1021 and two limiting parts 1022. The two welded parts 1021 can be welded to the outer shell of the lens assembly 300 first, specifically welded to the diagonal position of the outer shell of the lens assembly 300. Then, the two opposing elastic support parts 101 of the first support frame 100 are respectively inserted into the two welded parts 1021, and the elastic support parts 101 are limited by the two limiting parts 1022.

[0057] The second support frame 200 is sleeved on the outside of the first support frame 100. A first receiving groove 202 can be provided on the inner side wall of the second support frame, wherein two elastic support parts 101 are inserted into the first receiving groove 202, and the other two elastic support parts 101 are inserted into the welded part 1021.

[0058] This allows for the suspension of the ground support frame 100. Since the connection between the first support frame 100 and the lens assembly 300 is established through the fixing part 102, the lens assembly 300 can be suspended. A ball bearing 1023 is provided on the elastic support part 101, serving as a rotation point. The movement of the lens assembly 300 within the second support frame 200 is achieved by the rolling of the ball bearing 1023 (located in the elastic support part 101 within the first receiving groove 202) within the first receiving groove 202 and the rolling of the ball bearing 1023 (located in the welded part 1021 within the welded part 1021) within the welded part 1021.

[0059] In addition, such as Figure 10 As shown, the two elastic support portions 101 inserted into the first receiving groove 202 can be fixed in the first receiving groove 202 by means of the assembly 1024. Specifically, the assembly 1024 can adopt a snap-fit ​​structure. First, the elastic support portion 101 is assembled with the assembly 1024, and then the assembled structure is slid into the first receiving groove 202. After the snap-fit ​​structure is unfolded, the assembly 1024 is restricted in the first receiving groove 202. Since the assembly 1024 can restrict the elastic support portion 101 from sliding out of the first receiving groove 202, the elastic support portion 101 is finally restricted in the first receiving groove 202, preventing the elastic support portion 101 from sliding out of the first receiving groove 202.

[0060] In some implementations, such as Figure 5 As shown, a second receiving groove 203 is provided on the outer side wall of the second support frame 200, and the second receiving groove 203 is used to install the coil assembly 201. This can further reduce the size of the image stabilization assembly.

[0061] In some implementations, such as Figure 7As shown, a third receiving groove 302 is provided on the side wall of the lens assembly 300, and the third receiving groove 302 is used to install the magnetic component 301. Specifically, on the outer shell of the lens assembly 300, at a position corresponding to the coil assembly 201, the third receiving groove 302 is provided, and the third receiving groove 302 is used to install the magnetic component 301. The size of the third receiving groove 302 is adapted to the size of the magnetic component 301. In this way, the magnetic component 301 is directly set on the outer shell of the lens assembly 300, without needing to be set on the intermediate shell (related technologies set it on the intermediate shell), thereby further reducing the size of the image stabilization component.

[0062] In the embodiments of this application, such as Figure 7 As shown, after the magnetic component 301 is installed in the third receiving groove 302, the third receiving groove 302 can be sealed with a dustproof component 303 to prevent dust from affecting the magnetism of the magnetic component 301 and to prevent the magnetic component 301 from falling off. The dustproof component 303 can be made of MYLAR sheet. Mylar sheet PET polyester film is a film formed by heating dimethyl terephthalate and ethylene glycol under the assistance of a relevant catalyst, undergoing transesterification and vacuum polycondensation, and biaxial stretching, which can achieve good dustproof effect.

[0063] In some implementations, such as Figure 5 As shown, the support assembly also includes a top shell 400 and a bottom shell 500. The top shell 400 is disposed on the top of the second support frame 200, and the bottom shell 500 is disposed on the bottom of the second support frame 200. Both the top shell 400 and the bottom shell 500 can be sheet metal parts. The top of the top shell 400 has a hollow structure, and the bottom shell 500 covers the entire bottom of the second support frame 200, providing protection for the internal components of the second support frame 200.

[0064] In some embodiments, the top of the first support frame 100 is provided with a first through hole 104, through which the lens of the lens assembly 300 can pass. In this way, when the lens assembly 300 moves along the optical axis, it can pass through the first through hole 104, providing the lens assembly 300 with more focal length options.

[0065] In some embodiments, the camera module of this application also includes a second rigid-flex board 700, on which a sensor 801, a processor 800, and a coil assembly 201 are disposed. The second rigid-flex board 700 is electrically connected to an external motherboard through a second connector 802.

[0066] In this embodiment of the application, the processor 800 may be an OISIC (Optical Image Stabilization) chip.

[0067] In this embodiment, sensor 801 can be a gyroscope (also known as an angular velocity sensor) or a Hall sensor. The gyroscope can sense jitter and measure the tilt angle caused by the jitter. The processor 800 then predicts the image offset caused by the tilt based on this angle. When the coil assembly 201 is energized, it generates a magnetic field that interacts with the magnetic component 301, pushing the lens assembly 300 to move. The Hall sensor senses electromagnetic fields and feeds back the lens's position information to the processor 800. The processor 800 adjusts the current in the coil assembly 201 based on the position feedback information, thereby adjusting the generated magnetic field and the force between the coil assembly 201 and the magnetic component 301, allowing the lens assembly 300 to move accurately to the desired position.
