[0001] The present application relates to the technical field of electronic products, and in particular to a camera module and an assembly method, and an electronic device. Background Art

[0002] Electronic devices are usually equipped with camera modules. In order to improve the quality of images or videos taken by the camera module, current camera modules usually include an optical image stabilization module. The optical image stabilization module drives some components in the camera module to move to correct the "optical axis offset" to obtain images or videos of relatively high quality. Summary of the invention

[0003] The embodiment of the present application provides a camera module with high usage intensity and relatively high image quality. Based on the camera module, an assembly method and electronic equipment of the camera module are also provided.

[0004] On the one hand, the embodiment of the present application provides a camera module of an electronic device, including a base, a lens, an anti-shake moving component and a shell, wherein the base is at least partially located in the inner cavity of the shell, the anti-shake moving component is movably installed between the base and the shell, and the anti-shake moving component moves through its position to compensate for the vibration optical path. Compared with designing a mounting groove for the anti-shake moving component on the base, the anti-shake moving component in the present application is installed between the base and the shell, and the anti-shake moving component is located in the external space of the base, so there is no need to design a mounting groove inside the base, which is beneficial to improving the use strength of the base on the basis of reducing the base processing technology, and the moving space of the anti-shake moving component is not limited by the base, which also improves the flexibility of the movement of the anti-shake moving component and improves the efficiency of compensating for the vibration optical path.

[0005] Based on one aspect, the embodiment of the present application also provides a first implementation method of one aspect:

[0006] The shell includes a circumferential side wall and a bottom wall. The first end of the circumferential side wall is connected to the bottom wall, and the second end forms an open structure. The base can be installed from the open structure to the inner cavity of the shell. The second end is connected and fixed to the base. The lens is installed on the base and the light inlet of the lens is located on the side of the open structure. The anti-shake moving component is located between the bottom wall and the base. One side of the shell in the camera module in this embodiment is an open structure. The outer end surface of the base mounted lens can be directly exposed to the outer wall of the shell, and there is no need to process a through hole on the shell for exposing the lens, which simplifies the processing technology of the shell. In addition, the base and the shell are assembled quickly, which improves the assembly efficiency.

[0007] Based on one aspect or the first implementation of one aspect, the present application embodiment further provides a second implementation of one aspect:

[0008] It also includes a cable, the first end of which is electrically connected to the anti-shake moving component, and the second end is located outside the shell to connect to the mainboard; the base has a mounting body located in the inner cavity of the shell, the mounting body and the shell form a cable mounting space in the circumferential direction, a portion of the cable is located in the cable mounting space, and there is a gap between the mounting body and the shell and the cable located between the mounting body and the shell. In this way, the gap between the cable mounting space formed by the mounting body and the shell is greater than the thickness of the cable, so that the cable can be relatively close to or away from the mounting body inside the cable mounting space to adapt to the change in the position of the anti-shake moving component and improve the flexibility of the movement of the anti-shake moving component.

[0009] Based on the second implementation of the first aspect, the present application embodiment further provides a third implementation of the first aspect:

[0010] The circumferential side wall of the shell has a notch connected to the open structure, and the base can be installed into the inner cavity of the shell through the notch. The cable installation space is formed between the circumferential side wall of the shell and the installation body. The second end of the cable passes through the cable installation space and then extends to the outside of the shell through the notch. The base can not only be installed into the inner cavity of the shell from one side of the open structure along the optical axis direction, but also can be installed into the shell from the notch opened in the circumferential direction, that is, the shell of this structure can realize the assembly of the shell and the base in different directions, which improves the flexibility of installing the base into the inner cavity of the shell.

[0011] Based on the third implementation of the first aspect, the present application embodiment further provides a fourth implementation of the first aspect:

[0012] The side wall section on the installation body opposite to the notch abuts against the side wall of the housing near the notch, and the side wall section has a partial notch for the cable to pass from the cable installation space to the notch, thereby preventing impurities such as air or particles in the external environment from entering the inner cavity of the housing.

[0013] Based on the fourth implementation of the first aspect, the present application embodiment also provides a fifth implementation of the first aspect:

[0014] The side wall section of the installation body opposite to the notch is also provided with a positioning groove, and the cable also has a section positioned in the positioning groove.

[0016] The cable is fixedly connected to the positioning groove by adhesive or tape. The adhesive fixation can be fixed by glue point fixation at multiple positions, or of course, the entire bottom of the positioning groove can be glued. This is conducive to reliable positioning of the second end of the cable.

[0017] Based on the first to sixth implementations of one aspect, the present application embodiment also provides a seventh implementation of one aspect:

[0018] The open structure of the housing is buckled and installed on the installation body from one end of the anti-shake moving component, so that the installation of the two is simple and reliable.

[0019] Based on one aspect, any one of the first to seventh implementation modes, the present application embodiment also provides an eighth implementation mode of one aspect:

[0020] The anti-shake moving part includes a photosensitive element, which is used to convert the light signal passing through the lens into an electrical signal; the photosensitive element is driven to move to realize the anti-shake function. The structure is relatively simple and easy to implement.

[0021] Alternatively or additionally, the housing is a stamping part or an injection molded part. When the same use strength is met, the thickness of the stamping part is relatively small, which can reduce the overall height of the module. Of course, the housing can also be an injection molded part, which is relatively light in weight and has relatively high insulation performance.

[0023] The base also includes a convex body located outside the inner cavity of the shell, and a step surface facing the shell is formed between the convex body and the installation body, and the shell abuts against the step surface. In this way, when the shell is assembled on the shell, the step surface can play a role in locating the installation position of the shell, so as to achieve rapid installation of the shell and improve the assembly efficiency of both the shell and the base.

[0046] Fig.14 The schematic diagram of the decomposition after the section view of adding the anti-shake structure to the camera module of the prior art. DETAILED DESCRIPTION

[0047] Please refer to Fig.14 , Fig.14 The schematic diagram of the decomposition after the section view of adding the anti-shake structure to the camera module of the prior art. The camera module usually includes main components such as a base 1', an anti-shake moving component 4', a lens 3', a cable 5' and a shell 2', wherein the anti-shake moving component 4' and the lens are mounted on the base 1', and the shell is snapped on the base 1' to protect the various components. And the shell is provided with a through hole for the lens to pass through. The anti-shake moving component 4' can be connected to the mainboard of the electronic device through the cable 5' to realize signal transmission. A groove needs to be designed on the base 1' for installing the anti-shake moving component 4'. In order to meet the requirements of optical image stabilization, the anti-shake moving component 4' can move inside the groove to compensate for the vibrating optical path.

[0048] Adding an anti-shake structure to the existing module structure will cause the overall volume of the module to be too large and the base structure to be complicated. At the same time, the opening of the groove on the base reduces the use strength of the base 1' to a certain extent.

[0049] Based on the above research findings, this paper proposes a technical solution to the above technical problems.

[0050] In the following, the terms "first", "second", etc. are used only for descriptive purposes and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0051] The electronic device provided in the embodiments of the present application may be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA) and other mobile terminals, or may also be a digital camera, a SLR camera / micro-single camera, a sports camera, a gimbal camera, a drone and other professional shooting equipment. The embodiments of the present application do not limit the specific type of the electronic device. For ease of understanding, the electronic device is taken as an example for explanation below. Those skilled in the art should understand that as long as the electronic device has a camera, it can adopt the camera module provided in the present application.

[0052] Please refer to Figure 1 , Figure 1 The electronic device includes a structure 100 and a camera module 200, wherein the camera module 200 is installed on the structure 100. Figure 1 The electronic device is shown as a mobile phone, and the camera module 200 is used as the rear camera of the mobile phone. Of course, the camera module 200 is not limited to Figure 1 It should be noted that the "front" in this article can be understood as the side facing the user when the user uses the electronic device, and correspondingly, the "back" of the electronic device is the side facing away from the user when the user uses the electronic device.

[0053] For a mobile phone, the camera module can be fixed to the middle frame of the mobile phone. The middle frame can be made of metal or plastic, and this application does not impose any restrictions on this.

[0054] The camera module 200 is used to capture static images or videos. The camera module mainly includes a base 1, a lens 3 and an anti-shake moving component. The anti-shake moving component can move relative to the base 1 to compensate for the vibration optical path, thereby improving the quality of the camera module capturing images or videos. The anti-shake moving component 4 can be a photosensitive element, and the object generates an optical image through the lens 3 and projects it onto the photosensitive element. The photosensitive element may include a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then transmits the electrical signal to an image signal processor (ISP) to convert it into a digital image signal. The image signal processor outputs the digital image signal to a digital signal processor (DSP) for processing. The digital signal processor converts the digital image signal into an image signal in a standard RGB, YUV or other format.

[0055] Of course, the anti-shake moving component 4 may also be other components that can compensate for the vibration of the optical path.

[0056] In some embodiments, the electronic device may include 1 or N camera modules 200 , where N is a positive integer greater than 1.

[0057] The light inlet of the lens 3 faces one side of the structure 100, and is used to shoot scenes outside the electronic device. As mentioned above, the installation position of the camera module 200 can be determined according to the specific product. The camera module 200 can be installed at any position of the electronic device. When the camera module 200 is used as a rear camera, it is mainly used to shoot scenes on the back of the electronic device.

[0058] Please refer to Figure 2 and Figure 3 , Figure 2 A three-dimensional schematic diagram of a camera module in an example provided in an embodiment of the present application;

[0059] Figure 3 for Figure 2 An exploded schematic diagram of the camera module is shown.

[0060] The lens 3 in the camera module 200 provided in the present application is mounted on the base 1. Usually, a mounting hole 13 is processed on the base 1. The lens 3 is mounted in the mounting hole 13. The light inlet at the front end of the lens 3 can extend out of the mounting hole 13. The specific shape of the mounting hole 13 can be determined according to the shape of the lens 3 frame. This article provides a specific example of the mounting hole 13 being a cylindrical hole. Of course, the mounting hole 13 can also be a hole of other shapes. Generally, the lens 3 is connected to the mounting hole 13 through a spring sheet or a ball. As long as the installation of the lens 3 can be achieved, it will be fine.

[0061] The camera module 200 in this embodiment also includes a housing 2, which is mainly used to be mounted on the outside of the base 1 to form a closed space, providing a relatively closed working space for each working component in the camera module 200 to improve the working performance of each component. In order to facilitate the assembly of each component on the base 1 and the housing 2, the housing 2 and the base 1 are usually two independent components, which are connected and fixed by mechanical connection or other methods, such as gluing or welding.

[0062] In this embodiment, the base 1 is at least partially located in the inner cavity 21 of the shell 2, and the anti-shake moving component 4 is movably installed between the base 1 and the shell 2, that is, the anti-shake moving component 4 is arranged between the inner end surface 12 of the base 1 and the bottom wall 23 of the shell 2. Please refer to Figure 4 Understand. The inner end surface 12 of the base 1 is located in the inner cavity 21 of the shell 2. The anti-shake moving component 4 can move in a plane perpendicular to the optical axis. Of course, it can also be deflected around a certain axis at a certain angle, as long as the vibration optical path can be compensated. The current anti-shake moving component 4 usually compensates for the vibration optical path through the first two translational movement methods. It should be noted that the "optical axis" described in this article is the direction in which the optical system transmits light, referring to the main light of the central field of view, which generally coincides with the center line of the optical system. For the direction of the optical axis, please refer to Figure 4 The direction a is indicated in the figure. Figure 4 for Figure 2 Schematic diagram of the decomposition after partial sectioning along the BB direction.

[0063] The anti-shake movable component 4 can be movably supported on the base 1 or on the housing 2. Of course, the anti-shake movable component 4 can also be movably supported on both the base 1 and the housing 2. During shooting, the position of the anti-shake movable component 4 is adjusted to compensate for the vibration optical path to improve the quality of the captured image.

[0064] Compared with designing a mounting groove for the anti-shake movable component 4 on the base 1, in the present application, the anti-shake movable component 4 is installed between the base 1 and the shell 2, and the anti-shake movable component 4 is located in the external space of the base 1. In this way, there is no need to design a mounting groove inside the base 1, which makes the module compact. At the same time, it is beneficial to improve the use strength of the base 1 on the basis of reducing the processing technology of the base 1, and the moving space of the anti-shake movable component 4 is not limited by the base 1, which also improves the flexibility of the movement of the anti-shake movable component 4 and improves the reliability of the vibration optical path compensation.

[0065] In this embodiment, see Figure 3 and Figure 8 The housing 2 includes a circumferential side wall, a first end of the circumferential side wall is connected to the bottom wall, a second end forms an open structure, and the second end is connected and fixed to the base 1. The lens 3 is mounted on the base 1, and the light inlet of the lens 3 is located on one side of the open structure, and the anti-shake moving component 4 is located between the bottom wall of the housing 2 and the base 1. In this way, the side of the base 1 away from the light inlet of the lens 3 can be installed into the inner cavity 21 of the housing 2 from the side of the open structure of the housing 2, or the open structure of the housing 2 is inserted and fixed on the base 1 from the side of the base 1 away from the light inlet of the lens 3.

[0066] One side of the shell 2 in the camera module 200 in this embodiment is an open structure, and the outer end surface 11 of the base 1 for mounting the lens 3 can be directly exposed on the outer wall of the shell 2, without processing a through hole on the shell 2 for exposing the lens 3, thereby simplifying the processing technology of the shell 2.

[0067] In this embodiment, the camera module 200 further has a flat cable 5, a first end 51 of the flat cable 5 is electrically connected to the anti-shake moving component 4, and a second end 52 of the flat cable 5 is located outside the housing 2 to connect to the mainboard of the electronic device, that is, the flat cable 5 is a communication cable between the anti-shake moving component 4 and the mainboard of the electronic device. The flat cable can be a flexible circuit board or other flexible wires that can perform electrical connection.

[0068] Please refer to Figures 4 to 5, wherein the base 1 has a mounting body 1-1 located in the inner cavity 21 of the shell 2, the mounting body 1-1 and the shell 2 form a cable installation space 20 in the circumferential direction, and a portion of the cable is located in the cable installation space 20, so that the cable can be arranged around the mounting body 1-1, and the mounting body 1-1 plays a guiding role for the cable 5 to a certain extent. The angle of the cable installation space 20 surrounding the mounting body 1-1 can be the entire circumference of the mounting body 1-1, that is, 360° circumferentially, and of course it can also be less than 360° circumferentially. This article shows an embodiment in which the angle of the cable surrounding the mounting body 1-1 is greater than 270 degrees and less than 360°. In another example, the angle of the cable installation space 20 surrounding the mounting body 1-1 can also be any value from 0° to 360°. It should be noted that when the angle is 0°, the cable 5 is not wound around the mounting body 1-1, and directly extends from the position close to the first end 51 to the outside of the shell 2. Usually, the angle of the cable installation space 20 surrounding the mounting body 1-1 is between 90° and 360°.

[0069] Furthermore, there is a gap between the installation body 1-1 and the housing 2 and the wiring therebetween; Figure 5 In a specific state, the flat cable 5 and the housing 2 have a gap t1, and the flat cable 5 and the installation body 1-1 have a gap t2. That is, the gap between the flat cable installation space 20 formed by the installation body 1-1 and the housing 2 is greater than the thickness of the flat cable, so that the flat cable can be relatively close to or away from the installation body 1-1 inside the flat cable installation space 20 to adapt to the change of the position of the anti-shake moving component 4 and improve the flexibility of the movement of the anti-shake moving component 4.

[0070] The anti-shake moving component 4 in this embodiment is located between the mounting body 1 - 1 and the housing 2 .

[0071] Please refer again Figure 8 In this embodiment, the circumferential side wall of the housing 2 has a notch 2a, which is connected to the open structure, and the base 1 can also be installed into the inner cavity 21 of the housing 2 from the notch 2a. In this way, the base 1 can not only be installed into the inner cavity 21 of the housing 2 from one side of the open structure along the optical axis direction, but also can be installed into the housing 2 from the notch 2a opened in the circumferential direction, that is, the housing 2 of this structure can realize the assembly of the housing 2 and the base 1 in different directions, which improves the flexibility of the base 1 being installed into the inner cavity 21 of the housing 2.

[0072] In this embodiment, the cable installation space 20 is formed between the circumferential side wall of the housing 2 and the wall section 15 of the installation body 1-1. Figure 82 shows an example of a rectangular box body, wherein the rectangular box body has only three circumferential side walls, and a notch 2a is formed on one side of the two opposite side walls. Of course, the shape of the circumferential side wall of the shell 2 is not limited to the description herein, and can be any form. The second end of the cable passes through the cable installation space 20 and then extends to the outside of the shell 2 from the notch 2a.

[0073] In this embodiment, in order to prevent impurities such as air or particles in the external environment from entering the inner cavity 21 of the shell 2, the installation body 1-1 can also be configured as follows.

[0074] Please refer to Figure 6 and Figure 7 In one example, the side wall section 14 on the installation body 1-1 opposite to the notch 2a abuts against the side wall of the shell 2 near the notch 2a, that is, the side wall section 14 plays a role in isolating the external space from the inner cavity 21 of the shell 2 where the installation body 1-1 is located. For the above-mentioned shell 2 which is a rectangular box body with a notch 2a on one side, the bottom wall 14a of the side wall section 14 abuts against the bottom wall 23 of the shell body, and the two ends of the side wall section 14 on the installation body 1-1 opposite to the notch 2a abut against the first circumferential side wall 24 and the second circumferential side wall 22 of the rectangular box body, respectively. Figure 6 The first boss portion 141 of the middle side wall section 14 abuts against the second circumferential side wall section 22, and the second boss portion 142 and the third boss portion 143 of the side wall section 14 abut against the first circumferential side wall 24 at the same time. A notch 14b is partially provided between the side wall section 14 and the first circumferential side wall section 24 for the cable 5 to pass from the cable installation space 20 to the notch 2a. The notch 14b is formed between the second boss portion 142 and the third boss portion 143.

[0075] In one example, the side wall section 14 on the installation body 1-1 opposite to the notch 2a is further provided with a positioning groove 1a, and the cable 5 also has a section positioned in the positioning groove 1a. That is, after the cable 5 passes through the cable installation space 20, it is further positioned and installed inside the positioning groove 1a, and then the second end 52 of the cable 5 passes through the notch 2a. In this embodiment, the cable 5 is further positioned inside the positioning groove 1a, which is conducive to the reliability of the cable installation.

[0076] In this embodiment, the cable 5 can be fixedly connected to the positioning groove 1a by adhesive. The adhesive fixation can be fixed by glue point fixation at multiple positions, and of course, the entire bottom of the positioning groove 1a can also be glued. The connection method is simple and easy to operate. Of course, the cable can also be fixedly connected to the inside of the positioning groove 1a by other methods, such as the cable is fixedly connected to the positioning groove 1a by tape.

[0077] In this embodiment, the open structure 2b of the housing 2 is snap-fitted and installed on the installation body 1-1 from one end of the anti-shake moving component 4. The housing 2 and the installation body 1-1 can be circumferentially fitted and fixed, that is, the installation body 1-1 is also provided with a fitting surface 16 in the circumference, which is used to fit with the circumferential side wall section of the housing 2, such as gluing. This greatly increases the convenience of assembling the housing 2 and the base 1.

[0078] In this embodiment, the housing 2 in the camera module of the electronic device can be a stamping part. When the same use strength is met, the thickness of the stamping part is relatively small, which can reduce the overall height of the module. Of course, the housing 2 can also be an injection molded part, which is relatively light in weight and has relatively high insulation performance.

[0079] In this embodiment, the base 1 of the camera module of the electronic device further includes a convex body 1-2 located outside the housing 2, and a stepped surface facing the housing 2 is formed between the convex body 1-2 and the mounting body 1-1, and the housing 2 abuts against the stepped surface. In this way, when the housing 2 is assembled on the housing 2, the stepped surface can play a role in positioning the installation position of the housing 2, so as to achieve rapid installation of the housing 2 and improve the assembly efficiency of the housing 2 and the base 1.

[0080] On the basis of the above-mentioned camera module, the electronic device in the present application has the above-mentioned camera module, so the electronic device also has the above-mentioned technical effects of the camera module.
