[0044] An embodiment of the present application provides a camera module, and the camera module of the present application is described in detail below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 8 The camera module includes: a shell 1; a first coil 2, which is arranged in the shell 1; a variable aperture 3, which is rotatably arranged outside the shell 1; a driving component 4, which is arranged in the shell 1 and at least partially extends outside the shell 1 to be connected with the variable aperture 3; and a first magnetic component 5, which is arranged in the shell 1 and connected to the driving component 4. The first magnetic component 5 is arranged opposite to the first coil 2 and has a gap between the first magnetic component 5 and the first coil 2; wherein, when the first coil 2 is energized, the first magnetic component 5 drives the driving component 4 to translate along the length direction of the shell 1 to change the aperture diameter of the variable aperture 3.

[0046] Specifically, the shell 1 is a rigid structure with a containing cavity inside. The first coil 2 and the driving component 4 are located inside the shell 1, and the shell 1 can protect them.

[0047] The variable aperture 3 is arranged in the camera module, so that the camera module can take photos with high definition and good effect. The variable aperture 3 is rotatably arranged outside the housing 1. By rotating the variable aperture 3, the aperture size of the aperture hole of the variable aperture 3 can be adjusted to control the amount of light entering the camera module, thereby improving the clarity of the photo.

[0048] The first coil 2 is disposed in the shell 1, and the first coil 2 can be fixedly connected to the inner wall of the shell 1, and the fixing method can be dispensing, welding, riveting, etc., and the embodiment of the present application does not make specific restrictions on this.

[0049] The driving component 4 is a rigid structural component. The driving component 4 is arranged inside the housing 1. A part of the driving component 4 extends out from the housing 1 and is connected to the variable aperture 3 outside the housing 1. The part inside the housing 1 is fixedly connected to the first magnetic component 5. The first magnetic component 5 and the first coil 2 are arranged opposite to each other with a certain gap between them. When the first coil 2 is energized, it will become an electromagnet and generate a magnetic field. This magnetic field will exert a force on the surrounding first magnetic component 5. Under the action of this force, the first magnetic component 5 drives the driving component 4 to translate along the length direction of the housing 1. The translation of the driving component 4 drives the variable aperture 3 to rotate, thereby realizing the position change of the variable aperture 3.

[0050] The first magnetic member 5 may be a driving magnet, and further, the driving magnet may be a bar magnet.

[0051] In the embodiment of the present application, since the first magnetic component 5 is directly connected to the driving component 4, the driving component 4 is directly driven to translate through the action of the first magnetic component 5, and then the variable aperture 3 is driven to rotate, and there is no need to set a flexible circuit board to connect the variable aperture 3, so that the connection between the driving component 7 and the variable aperture 3 is more reliable, the reliability of the variable aperture 3 is improved, and the cost of the camera module is reduced. Moreover, since the first coil 2 and the first magnetic component 5 are relatively small in size, the first coil 2 and the first magnetic component 5 are integrated inside the shell 1, which can reduce the size of the camera module.

[0052] Optionally, a portion of the driving assembly 4 extending outside the housing 1 is provided with a protrusion 40 , an arc-shaped hole 30 is provided on the variable aperture 3 , and the protrusion 40 is embedded in the arc-shaped hole 30 and is movable in the arc-shaped hole 30 .

[0053] Specifically, the protrusion 40 can be a columnar structure, and the variable aperture 3 is provided with an arc hole 30. The arc hole 30 extends on the variable aperture 3 along the direction of rotation of the variable aperture 3 and has a certain curvature, so that when the protrusion 40 moves in the arc hole 30, the variable aperture 3 rotates at a certain angle as the protrusion 40 moves in the arc hole 30, so that the translation of the driving component 4 can be converted into the rotation of the variable aperture 3. In this embodiment, the driving component 4 can directly drive the variable aperture 3 to rotate through the movement of the protrusion 40 in the arc hole 30. This direct transmission method reduces the intermediate links, improves the response speed and control accuracy, and enables the variable aperture 3 to adjust its position more quickly and accurately. And only through the cooperation of the protrusion 40 and the arc hole 30, the conversion of the parallel movement of the driving component 4 and the rotation of the variable aperture 3 is realized, and the rotation of the variable aperture 3 is more simply realized, making the structure of the camera module simpler.

[0054] Optionally, a guide groove 10 is provided on the housing 1 , and the guide groove 10 extends along the translation direction of the driving assembly 4 . The driving assembly 4 is connected to the variable aperture 3 through the guide groove 10 , and the guide groove 10 is used to guide the translation of the driving assembly 4 .

[0055] Specifically, the housing 1 includes a horizontal surface and a vertical surface arranged vertically, and a guide groove 10 is provided on the horizontal wall. The guide groove 10 extends along the direction of translation of the driving assembly 4. The guide groove 10 can be any shape such as a rectangle or an ellipse. A part of the driving assembly 4 passes through the guide groove 10 and is connected to the variable aperture 3, and the other part is connected to the first magnetic member 5. In practical applications, when the first magnetic member 5 drives the driving assembly 4 to translate, the driving assembly 4 can translate in the guide groove 10, and the guide groove 10 plays a guiding role in the translation of the driving assembly 4, thereby making the translation process of the driving assembly 4 smoother and more stable.

[0056] Optionally, the variable aperture 3 includes at least two aperture blades 31, at least two of the aperture blades 31 are stacked, and the arc hole 30 is provided on one side of each of the aperture blades 31 close to the raised portion 40, and the raised portion 40 is embedded in the arc hole 30 of each of the aperture blades 31, and a light-through hole 32 is provided on each of the aperture blades 31, and the raised portion 40 moves in the arc hole 30, and each of the light-through holes 32 forms an aperture hole with a variable aperture.

[0057] Specifically, the aperture blade 31 is provided with a light hole 32. When the number of the aperture blade 31 is one, the area range of the light hole 32 of one aperture blade 31 is small, that is, the total amount of light received by the camera module has a small range of variation, and the camera cannot meet the shooting requirements in more scenes. Therefore, the variable aperture 3 includes at least two aperture blades 31, at least two aperture blades 31 are stacked, that is, at least two aperture blades 31 are combined together, and each aperture blade 31 is provided with a light hole 32; when the driving component 4 drives at least two aperture blades 31 to rotate, each light hole 32 forms an aperture hole with a variable aperture.

[0058] The embodiment of the present application does not limit the specific shapes of the aperture blades 31 and the light-through hole 32. Optionally, the aperture blades 31 may be circular or polygonal, and the light-through hole 32 may be rectangular, pentagonal, or other shaped holes.

[0059] Specifically, refer to Figure 1 The variable aperture 3 is rotatably arranged on the outer side of the housing 1, and each aperture blade 31 is provided with an arc hole 30, and the protrusion 40 is embedded in the arc hole 30 of each aperture blade 31. The driving component 4 drives the protrusion 40 to move in the arc hole 30, and then drives each aperture blade 31 to rotate relatively, so that each light-passing hole 32 forms an aperture hole with a variable aperture, that is, in the process of the driving component 4 driving at least two aperture blades 31 to rotate, the area of ​​the aperture hole can be continuously changed, and then the total amount of light received by the camera module changes continuously, so that the camera module can receive more light with different total amounts. Therefore, the camera module can be more suitable for shooting in a variety of scenes, and then the quality of the photos taken by the camera module is further improved.

[0060] Optionally, the driving assembly 4 includes: a mounting member 41 and a moving member 42; the mounting member 41 is fixedly connected to the outside of the shell 1; the variable aperture 3 is rotatably connected to the mounting member 41; the moving member 42 is arranged in the shell 1, and the portion at least partially extending to the outside of the shell 1 is provided with the protrusion 40, the first magnetic member 5 is fixedly connected to the moving member 42, and the first magnetic member 5 drives the moving member 42 to translate on the mounting member 41.

[0061] Specifically, the mounting member 41 is fixedly connected to the outer side of the housing 1, and the variable aperture 3 is rotatably connected to the mounting member, so that the variable aperture 3 can be rotatably arranged on the outer side of the housing. Further, the mounting member can be fixed to the outer side of the housing 1 by glue.

[0062] Furthermore, positioning holes 33 are provided on opposite sides of the plurality of aperture blades 31, and positioning posts 413 are provided at positions corresponding to the positioning holes 33 on the mounting member 41, and the aperture blades 31 can be rotatably connected to the mounting member 41 by passing the positioning posts 413 through the positioning holes 33. The positioning posts 413 are used to provide a rotation axis for the rotation of the aperture blades 31, and the design of the positioning posts 413 and the positioning holes 33 makes the aperture blades 31 more stable during rotation, reducing the risk of failure due to looseness or misalignment. The number of positioning holes 33 can be 2, 3, etc., and can be specifically selected according to the size of the variable aperture.

[0063] Specifically, the movable part 42 can be an integrated structure. The movable part 42 of the integrated structure has one end that is movably located inside the shell and is fixedly mounted on the first magnetic part 5. The other part is provided with a protrusion 40, which is connected to the variable aperture 3 through the protrusion 40. When the movable part 42 is an integrated structure, the cost of the camera module can be saved. However, when installing the movable part 42 of the integrated structure, it is necessary to first connect the movable part 42 to the variable aperture 3, and then connect the movable part 42 to the shell 1, and then install the shell 1 on other components, which makes the assembly process of the camera module more complicated. In order to make the assembly process of the camera module simpler, the movable part 42 can be set as a split structure, one of the split structures is connected to the shell 1 and extends out of the shell 1, and the other is set outside the shell 1 and is provided with a protrusion 40 connected to the variable aperture 3. After the split structures are assembled separately, the split structures are directly connected to each other, which makes the assembly process of the camera module simpler.

[0064] Optionally, the moving member 42 includes a first moving member 421 and a second moving member 422, the first magnetic member 5 is fixedly connected to the first moving member 421, and the first moving member 421 at least partially extends outside the shell 1; the second moving member 422 is connected to the portion of the first moving member 421 extending outside the shell 1, and the protrusion 40 is provided on the second moving member 422.

[0065] Specifically, the first moving member 421 is a flat plate structure, and the lower end of the flat plate-shaped first moving member 421 is fixedly connected with the strip-shaped first magnetic member 5, and the shape of the lower end of the first moving member 421 is adapted to the shape of the strip-shaped first magnetic member 5. Further, the first magnetic member 5 can be attached to the lower end of the first moving member 421;

[0066] The second mobile member 422 is also a plate-like structure, and the second mobile member 422 can have a horizontal plate and a vertical plate connected to the horizontal plate, and the horizontal plate extends to the aperture blades and is provided with a boss 40 on the arc hole 30 position, and the vertical plate extends perpendicular to the translation direction and is connected with the first connecting plate. It should be noted that the horizontal plate and the vertical plate are only for distinguishing the different structures of the second mobile member, and the specific shape of the second mobile member is not limited. In practical applications, the second mobile member 422 can be set to any shape, and can be specifically selected according to practical applications.

[0067] In this embodiment, the moving part 42 is configured as a first moving part 421 and a second moving part 422 of a split structure, one is arranged in the shell 1 and extends out of the shell 1, and the other is arranged outside the shell 1 and has a protrusion 40 connected to the variable aperture 3, so that the first moving part 421 and the second moving part 422 can be connected after they are assembled separately, making the camera module assembly process simpler.

[0068] Optionally, a flange 4210 is formed on the portion of the first movable member 421 extending outside the shell 1, and a slot 4221 is formed on the second movable member 422 at a position corresponding to the flange, and the flange 4210 is snapped into the slot 4221 to fix the second movable member 422 to the first movable member 421.

[0069] Specifically, the upper end of the flat plate-shaped first moving member 421 along the thickness direction of the housing 1 is formed with a flange 4210, and the flange 4210 extends perpendicularly to the translation direction. The second moving member 422 has a horizontal plate and a vertical plate connected to the horizontal plate, and the horizontal plate is provided with a protrusion 40 at the position extending to the arc hole 30 along the translation direction, and the vertical plate extends perpendicularly to the translation direction. A slot 4221 is formed on the vertical plate corresponding to the flange 4210, and the size of the flange 4210 is adapted to the structure of the slot 4221. In practical applications, the second moving member 422 can be connected to the first moving member 421 more stably by snapping the flange 4210 into the slot 4221, thereby improving the reliability of the connection between the second moving member 422 and the first moving member 421, and since snapping is a relatively simple and convenient installation method, the convenience of assembling the second moving member 422 and the first moving member 421 can be improved.

In practical applications, the light inlet 12, the light through hole 32 and the mounting hole 412 are arranged opposite to each other and are all located in the optical axis direction of the lens 6. Light can enter the lens 6, so that the lens 6 can take photos with high definition and good effect. The lens 6 is the main component of the camera module for shooting. By arranging the lens 6 in the housing 1, the lens 6 can be protected by the housing 1.

[0072] Specifically, the driving member 7 includes an electrical connector 72, a mounting frame 70, and an electromagnetic driver 71. The housing 1 is fixedly connected to the mounting frame 70. The electrical connector 72 is fixedly mounted on the mounting frame 70, and can be connected by dispensing, welding, etc. The electromagnetic driver 71 is arranged in the mounting frame 70 and is connected to the lens 6. The lens 6 is the main component of the camera module for shooting. During the shooting process, the lens 6 is more likely to shake, so the anti-shake function of the lens 6 can be achieved through the electromagnetic driver 71. The electromagnetic driver 71 drives the lens 6 to perform optical anti-shake movement, thereby achieving the anti-shake function of the lens 6. The driving component can also drive the lens 6 to perform auto-focus movement, thereby achieving the auto-focus function of the lens 6. The electromagnetic driver 71 can include multiple groups of second magnetic parts and second coils, and the anti-shake function and focusing function of the lens 6 are respectively achieved through multiple groups of second magnetic parts and second coils. Exemplarily, the second magnetic member and the second coil may be three groups, one group is arranged in the length X direction of the shell, one group is arranged in the width Y direction of the shell, and the other group is arranged in the height Z direction of the shell.
