[0023] Combine the following Figures 1 to 8 Describe a camera module and an electronic device according to an embodiment of the present application.

[0024] like Figures 1 to 4 As shown, a camera module according to some embodiments of the present application includes an image sensor 820, a first lens 100, a lens assembly 200 and a flexible member 300; the lens assembly 200 and the image sensor 820 are respectively arranged on both sides of the first lens 100, and the external light passes through the lens assembly 200 and the first lens 100 and is received by the image sensor 820; the flexible member 300 is arranged between the first lens 100 and the lens assembly 200, and the opposite sides of the flexible member 300 are respectively in contact with the first lens 100 and the lens assembly 200, and the lens assembly 200 can be relative to the first lens 100. 00 moves and squeezes the flexible part 300 to deform, and the flexible part 300 includes a light-transmitting portion 310 and a light-shielding portion 320; when the electronic device is in a first shooting mode, the distance between the lens assembly 200 and the first lens 100 is a first distance, and the projection area of ​​the light-transmitting portion 310 on the first lens 100 is a first area; when the electronic device is in a second shooting mode, the distance between the lens assembly 200 and the first lens 100 is a second distance, and the projection area of ​​the light-transmitting portion 310 on the first lens 100 is a second area; wherein the first distance is smaller than the second distance, and the first area is larger than the second area.

[0025] According to the camera module of the embodiment of the present application, it includes a first lens 100, a lens assembly 200 and a flexible member 300, the flexible member 300 is arranged between the first lens 100 and the lens assembly 200, the flexible member 300 includes a light-transmitting portion 310 and a light-shielding portion 320, and the light-shielding portion 320 is arranged around the light-transmitting portion 310, so that the flexible member 300 can be used as an aperture of the camera module. The aperture of the light-shielding portion 320 in the radial direction of the lens assembly 200 can increase or decrease with the movement of the lens assembly 200. When the electronic device is in the first shooting mode, the distance between the lens assembly 200 and the first lens 100 is the first distance, and the projection area of ​​the light-transmitting portion 310 on the first lens 100 is the first area; when the electronic device is in the second shooting mode, the distance between the lens assembly 200 and the first lens 100 is the second distance, and the projection area of ​​the light-transmitting portion 310 on the first lens 100 is the second area; wherein the first distance is less than the second distance, and the first area is greater than the second area, so as to adjust the aperture diameter D. By using the flexible member 300 as the aperture of the camera module, the structure of the aperture is simplified, and then the assembly process of the aperture is simplified, the difficulty of assembling the aperture is reduced, and it is more convenient for operators to assemble the aperture. In addition, while simplifying the aperture structure, the cost of the aperture can also be reduced, and then the cost of the camera module can be reduced. By using the flexible member 300 as the aperture of the camera module, the assembly process of the aperture can be simplified, and then the assembly process of the camera module is also simplified, thereby improving the assembly efficiency of the camera module.

[0026] Specifically, the first shooting mode may be a shooting mode that requires a short focal length for shooting, such as a close-up mode. In this mode, to ensure shooting brightness and clarity, the camera is in a large aperture state to obtain higher quality imaging; the second shooting mode may be a shooting mode that requires a long focal length for shooting, such as a long-range shooting mode. In this mode, to avoid overexposure or blur, the camera is in a small aperture state to obtain higher quality imaging.

[0027] The camera module of the embodiment of the present application can be used in electronic devices.

[0028] According to some embodiments of the present application, Figure 5 and Figure 6 As shown, the light-transmitting portion 310 includes a first light-transmitting portion 330 and a second light-transmitting portion 340; the first light-transmitting portion 330 is connected to the first lens 100 and to the first side of the light-shielding portion 320; the second light-transmitting portion 340 is connected to the lens assembly 200 and to the second side of the light-shielding portion 320.

[0029] In this embodiment, the light-transmitting portion 310 includes a first light-transmitting portion 330 and a second light-transmitting portion 340, so that light from outside the camera module can penetrate the flexible member 300 and be received by the image sensor 820 to achieve imaging. The first light-transmitting portion 330 is connected to the first lens 100, so that the side of the flexible member 300 close to the first lens 100 is fixed by the first lens 100. The second light-transmitting portion 340 is connected to the lens assembly 200, so that the side of the flexible member 300 close to the lens assembly 200 can move with the movement of the lens, and then the flexible member 300 can be stretched or compressed by the lens assembly 200 to adjust the aperture size.

[0030] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, the light-transmitting portion 310 includes a fitting portion 312 and a deformable portion 314 ; the fitting portion 312 is fitted to the first lens 100 ; the deformable portion 314 is annular and is arranged around the fitting portion 312 , the inner edge of the deformable portion 314 is connected to the fitting portion 312 , and the outer edge of the deformable portion 314 is connected to the light-shielding portion 320 .

[0031] In this embodiment, the light-transmitting portion 310 includes a fitting portion 312 and a deformable portion 314. The fitting portion 312 is fitted to the first lens 100 to support and fix the light-transmitting portion 310. The deformable portion 314 has an arc-shaped cross section, the inner circle of the deformable portion 314 is connected to the fitting portion 312, and the outer circle of the deformable portion 314 is connected to the light-shielding portion 320. Figure 1 and Figure 2 As shown, when the deformation portion 314 and the bonding portion 312 are both bonded to the first lens 100 and / or the lens assembly 200, the outer diameter of the deformation portion 314 is at its maximum state, at which time the diameter of the aperture is the largest and the field of view (FOV) is the largest. Figure 3 and Figure 4 As shown, when the outer circle of the deformation portion 314 is away from the first lens 100, the inner circle of the deformation portion 314 is connected to the fitting portion 312 and fixed on the first lens 100 and / or the lens assembly 200, and the outer circle of the deformation portion 314 is away from the first lens 100 and converges toward the optical axis, so that the diameter of the deformation portion 314 is reduced and the field of view angle e is reduced, thereby achieving adjustment of the aperture size.

[0032] Furthermore, the aperture size can be adjusted by driving the flexible member 300 to deform through the movement of the lens assembly 200, thereby increasing the adjustment range and amplitude of the aperture and improving the shooting effect of the camera module.

[0033] Furthermore, if Figure 7 and Figure 8As shown, the first light-transmitting portion 330 includes a first fitting portion 332 and a first deformable portion 334; the first fitting portion 332 is fitted to the first lens 100; the first deformable portion 334 is annular and is arranged around the first fitting portion 332, the inner edge of the first deformable portion 334 is connected to the first fitting portion 332, and the outer edge of the first deformable portion 334 is connected to the shading portion 320.

[0034] The second light-transmitting portion 340 also includes a second fitting portion 342 and a second deforming portion 344, the second fitting portion 342 is fitted to the lens assembly 200; the second deforming portion 344 is annular and is arranged around the second fitting portion 342, the inner edge of the second deforming portion 344 is connected to the second fitting portion 342, and the outer edge of the second deforming portion 344 is connected to the shading portion 320.

[0035] Furthermore, the flexible member 300 can be deformed, but will not stretch or will stretch only slightly when deformed. The flexible member 300 may also have a certain flexibility, but no elasticity or less elasticity, thereby improving the accuracy of the aperture size control.

[0036] Specifically, the bonding portion 312 is bonded to the first lens 100 and / or the lens assembly 200 by optical adhesive (OCA).

[0037] According to some embodiments of the present application, Figures 5 to 8 As shown, there are at least two layers of flexible members 300 , and the bonding portion 312 of one layer of the at least two layers of flexible members 300 is bonded to the first lens 100 , and the bonding portion 312 of the other layer of the flexible member 300 is bonded to the lens assembly 200 .

[0038] In this embodiment, the bonding portion 312 of one layer of the at least two layers of flexible parts 300 is bonded to the first lens 100, and the bonding portion 312 of the other layer of the flexible part 300 is bonded to the lens assembly 200. During the movement of the lens assembly 200, the flexible part 300 can be driven to move, thereby adjusting the aperture size while focusing, so that the aperture size can match the focal length, thereby improving the imaging effect of the camera module.

[0039] The lens assembly 200 is used to drive the elastic membrane to move to adjust the aperture structure, and there is no need to set up a separate driving structure to drive the aperture, which further simplifies the structure of the camera module, reduces the size of the camera module, and reduces the space occupied by the camera module, thereby facilitating the lightweight design of electronic equipment.

[0041] like Figure 5 and Figure 6 As shown, in the process of the lens assembly 200 approaching the first lens 100, the fitting portion 312 of the second light-transmitting portion 340 approaches the fitting portion 312 of the first light-transmitting portion 330, and the outer circle of the deformation portion 314 of the first light-transmitting portion 330 approaches the first lens 100 and expands in the direction away from the optical axis of the camera module. When the outer circle of the deformation portion 314 of the second light-transmitting portion 340 approaches the lens assembly 200, it expands in the direction away from the optical axis of the camera module, and the diameter of the aperture expands.

[0042] like Figure 7 and Figure 8 As shown, in the process of the lens assembly 200 moving away from the first lens 100, the fitting portion 312 of the second light-transmitting portion 340 moves away from the fitting portion 312 of the first light-transmitting portion 330, and the outer circle of the deformation portion 314 of the first light-transmitting portion 330 moves away from the first lens 100 while tightening in the direction close to the optical axis of the camera module, and the outer circle of the deformation portion 314 of the second light-transmitting portion 340 moves away from the lens assembly 200 while tightening in the direction close to the optical axis of the camera module, and the diameter of the aperture is reduced.

[0043] According to some embodiments of the present application, Figure 2 As shown, a first ink layer 910 is disposed on the surface of the light shielding portion 320 .

[0044] In this embodiment, the light shielding portion 320 is coated with a first ink layer 910, which can effectively reduce the light transmittance of the light shielding portion 320, thereby forming an aperture on the flexible member 300. In addition, the coating process of the first ink layer 910 is simple, which facilitates the control of the coating area, and then facilitates the control of the shape of the aperture, so that the aperture and the lens are adapted to improve the imaging effect of the camera module.

[0046] In this embodiment, the shell 710 is cylindrical, and the first lens 100 and the lens assembly 200 are arranged in the shell 710 to support and protect the first lens 100 and the lens assembly 200. The protective cover 720 is covered on the first end of the shell 710 to prevent dust and other impurities from entering the shell 710, thereby improving the cleanliness of the interior of the shell 710 and preventing dust and other impurities from affecting the imaging effect of the camera module.

[0047] A slide rail 730 is provided on the housing 710 along the optical axis direction of the camera module, and a slider capable of cooperating with the slide rail 730 is provided on the lens assembly 200. When the lens assembly 200 moves along the optical axis direction, the slide rail 730 and the slider cooperate to guide the lens assembly 200, so that the lens assembly 200 can stably move along the optical axis direction, thereby improving the stability of the movement of the lens assembly 200 during the focusing process.

[0054] There are multiple first gears 420 , and the multiple first gears 420 can adjust the rotation speed, further improving the stability of the motor 410 driving the lens assembly 200 to move.

[0057] In this embodiment, the transmission component 600 includes a gear or a rack, which is fixedly connected to the lens assembly 200. When the screw 500 rotates, it can drive the gear or rack to move along the axial direction of the screw 500, thereby driving the lens assembly 200.

[0058] Specifically, the transmission component 600 is a rack, which is connected to the lens bracket of the lens assembly 200, thereby driving the lens assembly 200.

Since the flexible part 300 of the camera module can adjust the aperture size under the drive of the lens assembly 200, thereby making the adjustment range and adjustment amplitude of the aperture larger, the camera module can simultaneously have the functions of a main camera, a portrait camera and an ultra-wide-angle camera, and then replace the original multiple cameras with a large-bottom camera with a variable aperture, thereby reducing the space required for the camera module, reducing the space occupied by the camera module on the electronic device, and facilitating the miniaturization and lightweight design of the electronic device.

[0069] Specifically, the viewing angle = H x WD / f.

[0070] Wherein, H is the imaging height, WD is the object distance, and f is the focal length.

[0071] When the object to be photographed is determined, the object distance and focal length are constant, while the photo size remains unchanged and the image height is also a constant.

[0072] Since the photo size remains unchanged, that is, the imaging height remains unchanged, if the field of view angle increases, the image around the subject will be cropped, causing the subject to be magnified; therefore, a smaller field of view angle is suitable for taking distant views, while a larger field of view angle is suitable for taking close views. This application adjusts the field of view angle by adjusting the size of the aperture diameter, so that the camera module has the ability to take both distant and close views.

[0073] According to some embodiments of the present application, the electronic device includes a mobile phone, a tablet computer, a laptop computer or an e-book.
