[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] With the development of science and technology, electronic devices generally have the function of obtaining image information. However, in the related art, the fixing effect of the camera module used to obtain image information in the electronic device is not good. Based on the above problems, the embodiments of the present application provide a lens barrel, a camera module, an electronic device and a processing method of the lens barrel, aiming to solve the above problems.

[0039] In a first aspect, an embodiment of the present application provides a lens barrel 100. Figure 1 as well as Figure 2 The lens barrel 100 includes a first structure portion 110 and a second structure portion 120. The first structure portion 110 is provided with a first receiving cavity 111 that penetrates therethrough. The second structure portion 120 is connected to the first structure portion 110, and the second structure portion 120 is provided with a second receiving cavity 121 that penetrates therethrough and communicates with the first receiving cavity 111. The outer diameter of one end of the second structure portion 120 connected to the first structure portion 110 is greater than the outer diameter of one end of the first structure portion 110 connected to the second structure portion 120, and the outer diameter of the first structure portion 110 gradually decreases in a direction from one end of the second structure portion 120 adjacent to the first structure portion 110 to one end away from the first structure portion 110.

[0040] In the embodiment of the present application, the lens barrel 100 is designed to include a first structure portion 110 and a second structure portion 120, and the first structure portion 110 and the second structure portion 120 form a structure with large ends and a small middle. In this way, when the lens barrel 100 is installed in the electronic device 1, the lens barrel 100 can be connected to a certain device installed in the electronic device 1 by plugging. When the lens barrel 100 is plugged with the device installed therein, the larger ends of the first structure portion 110 and the second structure portion 120 can restrict the lens barrel 100 to the device installed therein, thereby preventing the lens barrel 100 from being separated from the device installed therein, and making the installation of the lens barrel 100 in the electronic device 1 more stable.

[0041] See also Figures 1 to 3 , the second structure portion 120 may be located on the image side of the first structure portion 110. Figure 4 , the first structure portion 110 may be located on the image side of the second structure portion 120 .

[0042] The lens barrel 100 is generally used to install the lens group 200 (see Figure 5 ), photosensitive chip 300 (see Figure 5) and other components. The lens group 200, the photosensitive chip 300 and other components can all be installed in the first receiving cavity 111 of the first structural part 110, or can all be installed in the second receiving cavity 121 of the second structural part 120. Of course, in order to improve the space utilization rate inside the lens barrel 100 and realize the miniaturization of the camera module 10, components can be installed in both the first receiving cavity 111 and the second receiving cavity 121. Since the photosensitive chip 300 needs to be located on the image side of the lens group 200, when the second structural part 120 is located on the image side of the first structural part 110 and components are installed in both the second receiving cavity 121 and the first receiving cavity 111, the second receiving cavity 121 can be used for the photosensitive chip 300, and the first receiving cavity 111 can be used for installing the lens group 200. When the lens group 200 includes multiple lenses, the first receiving cavity 111 can be used to install all the lenses of the lens group 200; of course, the first receiving cavity 111 can also be used to install part of the lenses of the lens group 200, so that the second receiving cavity 121 can be used to install the remaining lenses of the lens group 200 and the photosensitive chip 300.

[0043] Similarly, since the photosensitive chip 300 needs to be located on the image side of the lens group 200, when the first structural part 110 is located on the image side of the second structural part 120 and components are installed in both the second receiving cavity 121 and the first receiving cavity 111, the second receiving cavity 121 can be used to install the lens group 200, and the first receiving cavity 111 can be used to install the photosensitive chip 300. When the lens group 200 includes multiple lenses, the second receiving cavity 121 can be used to install all the lenses of the lens group 200; of course, the second receiving cavity 121 can also be used to install some of the lenses of the lens group 200, so that the first receiving cavity 111 can be used to install the remaining lenses of the lens group 200 and the photosensitive chip 300.

[0044] The photosensitive chip 300 generally has a regular three-dimensional geometric structure. For example, the photosensitive chip 300 is generally in the shape of a rectangular parallelepiped. From the end of the photosensitive chip 300 adjacent to the lens group 200 to the end away from the lens group 200, the outer diameter of the photosensitive chip 300 generally remains unchanged. Based on this, in order to make the structure of the lens barrel 100 compact, the photosensitive chip 300 can be installed in the second receiving cavity 121 instead of the first receiving cavity 111 of the first structural part 110 whose outer diameter gradually changes. Figure 5 When the photosensitive chip 300 is installed in the second receiving cavity 121, the lens group 200 can be installed in the first receiving cavity 111. Since the photosensitive chip 300 needs to be located on the image side of the lens group 200, the second structure part 120 is located on the image side of the first structure part 110. In order to further reduce the structure of the lens barrel 100, the second receiving cavity 121 of the second structure part 120 can be set to match the photosensitive chip 300. In order to make the structure of the second structure part 120 stable, the wall thickness of the second structure part 120 can be equal everywhere.

[0045] From the end of the second structure part 120 adjacent to the first structure part 110 to the direction away from the end of the first structure part 110, the outer diameter of the first structure part 110 gradually decreases, and the outer peripheral surface of the first structure part 110 can be a prism, a truncated cone, a combination of prisms with gradually increasing outer diameters, a combination of truncated cones with gradually increasing outer diameters, etc. Of course, in order to make the outer surface of the lens barrel 100 relatively smooth, the outer diameter of the first structure part 110 can be reduced in sequence from the end of the second structure part 120 adjacent to the first structure part 110 to the direction away from the end of the first structure part 110. The sequential reduction here can be: the outer boundary line of the cross section of the first structure part 110 through the first plane includes a first side line and a second side line, the first side line is a straight line or a smooth curve, and the second side line is a straight line or a smooth curve. The first plane can be the plane where the optical axis of the lens barrel 100 is located. The first side line and the second side line can be the boundary lines in the cross section corresponding to the outer peripheral surface of the first structure part 110.

[0046] To make the outer surface of the lens barrel 100 smooth, see Figure 1 When the lens assembly 200 is installed in the first receiving cavity 111 of the first structural part 110, since the outer circumference of the lens assembly 200 is generally a cylindrical surface or a truncated cone surface, the first receiving cavity 111 for installing the lens assembly 200 can be configured to match the lens assembly 200. In this way, when the outer circumference of the first structural part 110 is also a truncated cone surface, the wall thickness of the first structural part 110 can be designed to be substantially equal (see Figure 3 ) to stabilize the structure of the first structural portion 110.

[0047] When the lens barrel 100 is connected to a certain device of the electronic device 1 by plugging, since the first structural part 110 and the second structural part 120 form a structure with large ends and small middle, the assembly and disassembly between the lens barrel 100 and the device installed in the lens barrel 100 needs to apply a certain force to complete. In order to ensure that the connection between the lens barrel 100 and the device is relatively stable and the assembly and disassembly between the lens barrel 100 and the device can be carried out smoothly, when the outer peripheral surface of the first structural part 110 is a truncated table surface, the angle between the generatrix of the outer peripheral surface of the first structural part 110 and the optical axis M of the lens barrel 100 can be less than or equal to 3°. Specifically, the angle between the generatrix of the outer peripheral surface of the first structural part 110 and the optical axis M of the lens barrel 100 can be 1°, 1.5°, 2°, 2.5°, 3°, etc.

[0048] In a second aspect, the present application embodiment provides a camera module 10. Figure 5The camera module 10 may include any of the above-mentioned lens barrels 100, lens groups 200, and photosensitive chips 300. The lens group 200 is disposed in the first receiving cavity 111 of the first structural part 110, and the photosensitive chip 300 is disposed in the second receiving cavity 121 of the second structural part 120. The lens group 200 includes at least one lens.

[0049] In the embodiment of the present application, the lens barrel 100 is designed to include a first structure portion 110 and a second structure portion 120, and the first structure portion 110 and the second structure portion 120 form a structure with large ends and a small middle. In this way, when the lens barrel 100 is installed in the electronic device 1, the lens barrel 100 can be connected to a certain device installed in the electronic device 1 by plugging. When the lens barrel 100 is plugged with the device installed therein, the larger ends of the first structure portion 110 and the second structure portion 120 can restrict the lens barrel 100 to the device installed therein, thereby preventing the lens barrel 100 from being separated from the device installed therein, and making the installation of the lens barrel 100 in the electronic device 1 more stable.

[0050] The camera module 10 can be installed and fixed in the electronic device 1 by installing and fixing the lens barrel 100 in the electronic device 1. To achieve the installation and fixation of the lens barrel 100 in the electronic device 1, the lens barrel 100 can be connected to any device of the electronic device 1 by plugging, and it is only necessary to ensure that the various functions of the electronic device 1 can be implemented normally.

[0051] Of course, since the space inside the electronic device 1 is relatively small, if the lens barrel 100 is plugged into the device of the electronic device 1, the disassembly and assembly operation of the lens barrel 100 is relatively inconvenient. Figure 6 The camera module 10 may further include a bracket 400 for mounting the lens barrel 100, so that the lens barrel 100 can be plugged into the bracket 400. The size of the bracket 400 may be set larger than the size of the lens barrel 100, so that the bracket 400 can be installed in the electronic device 1 more conveniently and stably. Specifically, the bracket 400 may include a first portion 410 arranged around the periphery of the first structural portion 110, and the first portion 410 is formed of a material that is deformable under the action of an external force, so that the first structural portion 110 can be arranged on the first portion 410, and the outer peripheral surface of the first structural portion 110 is in contact with the inner peripheral surface of the first portion 410. The preparation material of the first portion 410 may be any material that is deformable under the action of an external force. For example, the preparation material of the first portion 410 may be silicone, rubber, etc.

[0052] In order to prevent the second structure part 120 of the lens barrel 100 from being exposed to the outside and being easily scratched, see Figure 7The bracket 400 may further include a second portion 420 arranged around the periphery of the second structural portion 120, and the second structural portion 120 may be arranged on the second portion 420. The outer peripheral surface of the second structural portion 120 may contact the outer peripheral surface of the second portion 420, or there may be a gap between the outer peripheral surface of the second portion 420. When the outer peripheral surface of the second structural portion 120 contacts the outer peripheral surface of the second portion 420, that is, when the lens barrel 100 is connected to the bracket 400, the first structural portion 110 contacts the first portion 410 and the second structural portion 120 contacts the second portion 420, the stability of the connection between the lens barrel 100 and the bracket 400 can be ensured. When there is a gap between the outer peripheral surface of the second structural portion 120 and the outer peripheral surface of the second portion 420, the structural design requirements for the outer peripheral surface of the second structural portion 120 and the outer peripheral surface of the second portion 420 are relatively low, which is convenient for the production and manufacturing of the lens barrel 100 and the bracket 400.

[0053] The second part 420 can be made of a material that is deformable under external force, and the material of the second part 420 is the same as that of the first part 410, so that the processing and molding of the bracket 400 is more convenient. Of course, in order to ensure the structural strength of the second part 420, the second part 420 can also be made of a material that is not deformable under external force.

[0054] To ensure the connection strength between the first structure portion 110 and the first portion 410, see Figure 8 The bracket 400 may further include a third portion 430 disposed around the periphery of the first portion 410, and the third portion 430 may be formed of a material that is not deformable under external force. In order to ensure that the lens barrel 100 is installed stably in the bracket 400, the outer diameter of one end of the first portion 410 adjacent to the second structural portion 120 may be smaller than the outer diameter of one end of the second structural portion 120 connected to the first structural portion 110, so that after the lens barrel 100 is installed with the bracket 400, the second structural portion 120 is still in contact with the third portion 430.

[0055] To prevent the lens barrel 100 from being easily scratched when exposed to the outside of the bracket 400, the length of the first portion 410 can be equal to the length of the first structure portion 110 along the direction parallel to the optical axis M of the lens barrel 100, and the length of the second portion 420 can be equal to the length of the second structure portion 120. Of course, to facilitate the disassembly and assembly between the lens barrel 100 and the bracket 400, see Fig. 9 , along a direction parallel to the optical axis M of the lens barrel 100 , the length of the first portion 410 may be smaller than the length of the first structural portion 110 ; and / or, along a direction parallel to the optical axis M of the lens barrel 100 , the length of the second portion 420 may be smaller than the length of the second structural portion 120 .

[0056] In a third aspect, an embodiment of the present application provides an electronic device 1. Fig.10The electronic device 1 includes any of the above-mentioned camera modules 10 and a housing. The camera module 10 is disposed in the housing. The electronic device 1 can be any device having a function of acquiring image information. For example, the electronic device 1 can be a smart phone, a wearable device, a computer device, a television, a vehicle, a camera, a monitoring device, etc.

[0057] In the embodiment of the present application, the lens barrel 100 is designed to include a first structure portion 110 and a second structure portion 120, and the first structure portion 110 and the second structure portion 120 form a structure with large ends and a small middle. In this way, when the lens barrel 100 is installed in the electronic device 1, the lens barrel 100 can be connected to a certain device installed in the electronic device 1 by plugging. When the lens barrel 100 is plugged with the device installed therein, the larger ends of the first structure portion 110 and the second structure portion 120 can restrict the lens barrel 100 to the device installed therein, thereby preventing the lens barrel 100 from being separated from the device installed therein, and making the installation of the lens barrel 100 in the electronic device 1 more stable.

[0058] In a fourth aspect, the present application embodiment provides a method for processing the lens barrel 100, see Fig.11 , processing methods include:

[0061] A portion of the outer circumferential surface of the first structure portion 110 is removed so that the outer diameter of the first structure portion 110 gradually decreases in a direction from an end of the second structure portion 120 adjacent to the first structure portion 110 to an end away from the first structure portion 110, and the outer diameter of the end of the second structure portion 120 connected to the first structure portion 110 is greater than the outer diameter of the end of the first structure portion 110 connected to the second structure portion 120.

[0062] In the embodiment of the present application, the lens barrel 100 is designed to include a first structure portion 110 and a second structure portion 120, and the first structure portion 110 and the second structure portion 120 form a structure with large ends and a small middle. In this way, when the lens barrel 100 is installed in the electronic device 1, the lens barrel 100 can be connected to a certain device installed in the electronic device 1 by plugging, and when the lens barrel 100 is plugged with the device installed therein, the larger ends of the first structure portion 110 and the second structure portion 120 can restrict the lens barrel 100 to the device installed therein, thereby preventing the lens barrel 100 from being separated from the device installed therein, and making the installation of the lens barrel 100 in the electronic device 1 more stable. The embodiment of the present application forms the lens barrel 100 by numerical control processing, with high processing efficiency and high processing precision, and can realize networked and intelligent production.
