[0044] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a camera module provided in an embodiment of the present application, Figure 2 yes Figure 1 The camera module 000 may include: a first lens group 100 , a second lens group 200 , a first sliding stopper 300 and a second sliding stopper 400 .

[0047] The first lens group 100 and the second lens group 200 in the camera module 000 can be arranged along the first direction f1, and the first lens group 100 and the second lens group 200 can be slidably connected, and the optical axes of the first lens group 100 and the second lens group 200 can be parallel to the first direction f1.

[0048] The first sliding stopper 300 in the camera module 000 may be connected to the first lens group 100 .

[0049] The second sliding stopper 400 in the camera module 000 may be connected to the second lens group 200 .

[0050] The second sliding stopper 400 may be configured to slide in cooperation with the first sliding stopper 300 to limit the sliding stroke of the second mirror group 200 relative to the first mirror group 100 along the first direction f1.

[0051] In the embodiment of the present application, the first lens group 100 and the second lens group 200 in the camera module 000 are arranged along the first direction f1, and the first lens group 100 and the second lens group 200 are slidably connected, so that the second lens group 200 can slide relative to the first lens group 100, so that the focal length of the camera module can be changed, and optical zoom and focus functions of different magnifications can be achieved. In this way, the user can select a suitable magnification for shooting according to different shooting scene requirements. However, for a camera module with zoom and focus functions, one lens group in the camera module may have a sliding stroke that is too large relative to another lens group, resulting in an undesirable phenomenon of imaging failure.

[0052] Here, by providing the first sliding stopper 300 on the first lens group 100 and providing the second sliding stopper 400 cooperating with the first sliding stopper 300 on the second lens group 200, the second sliding stopper 400 and the first sliding stopper 300 cooperate with each other to limit the travel of the second lens group 200 when sliding relative to the first lens group 100, thereby effectively avoiding the undesirable phenomenon of shooting failure caused by the second lens group 200 sliding with an excessive travel relative to the first lens group 100. At the same time, it can also avoid the undesirable phenomenon of the two lens groups being separated after the electronic device integrated with the camera module falls.

[0053] It should be noted that the first lens group 100 may include a first lens frame and at least one lens (not shown in the figure) fixed in the first lens frame; the second lens group 200 may include a second lens frame and at least one lens (not shown in the figure) fixed in the second lens frame. When the second lens group 200 moves relative to the first lens group 100 along the first direction f1, the lens in the second lens group 200 can move relative to the lens in the first lens group 100 to achieve a zoom function or a focus function.

[0054] In summary, the embodiment of the present application provides a camera module, which may include: a first lens group, a second lens group, a first sliding stopper and a second sliding stopper. By arranging the first lens group and the second lens group in the camera module along the first direction, and after the first lens group and the second lens group are slidably connected, the second lens group can slide relative to the first lens group, so that the focal length of the camera module can be changed, and optical zoom and focus functions of different magnifications can be achieved. In this way, the user can select a suitable magnification for shooting according to different shooting scene requirements. In addition, by setting the first sliding stopper on the first lens group and setting the second sliding stopper on the second lens group to cooperate with the first sliding stopper, the second sliding stopper and the first sliding stopper can be used to limit the travel of the second lens group when sliding relative to the first lens group, thereby effectively avoiding the undesirable phenomenon of the second lens group sliding with an excessive travel relative to the first lens group and causing shooting failure. At the same time, it can also avoid the undesirable phenomenon of the two lens groups being separated after the electronic device integrated with the camera module falls.

[0059] In the embodiments of the present application, Figure 3 and Figure 4As shown, the first sliding stopper 300 in the camera module 000 may include: at least one of a first sub-stopper 301 fixed on the support portion 102 in the first lens group 100 and a second sub-stopper 302 fixed on the first lens group body 101. The second sliding stopper 400 in the camera module 000 may include: at least one of a third sub-stopper 401 fixed on the second lens group body 201 and a fourth sub-stopper 402 fixed on the sliding connection portion 202. Wherein, in the case where the first sliding stopper 300 includes the first sub-stopper 301, the second sliding stopper 400 may include the third sub-stopper 401, and the first sub-stopper 301 and the third sub-stopper 401 may be connected in a matching manner. In the case where the first sliding stopper 300 includes the second sub-stopper 302, the second sliding stopper 400 may include the fourth sub-stopper 402, and the second sub-stopper 302 and the fourth sub-stopper 402 may be connected in a matching manner.

[0060] In this case, when the first sliding limit member 300 includes both the first sub-limit member 301 and the second sub-limit member 302, and the second sliding limit member 400 includes both the third sub-limit member 401 and the fourth sub-limit member 402, the cooperation between the first sub-limit member 301 and the third sub-limit member 401, and the cooperation between the second sub-limit member 302 and the fourth sub-limit member 402 can ensure the stability of the second mirror group body 201 when it slides relative to the first mirror group body 101, and can prevent the undesirable phenomenon of deflection of the second mirror group body 201 when it slides relative to the first mirror group body 101.

[0061] Optional, please refer to Figure 5 , Figure 5 1 is an exploded schematic diagram of another camera module provided by an embodiment of the present application. The support portion 102 in the first mirror group 100 may include: a first support plate 102a and a second support plate 102b connected to each other. The first support plate 102a and the second mirror group body 201 may be arranged along the second direction f2, the first mirror group body 101 and the sliding connection portion 202 in the second mirror group 200 may be arranged along the second direction f2, and the second support plate 102b and the second mirror group body 201 may be arranged along the third direction f3. Wherein, the second direction f2 may intersect with the third direction f3, and both the second direction f2 and the third direction f3 may intersect with the first direction f1. For example, the second direction f2 may be perpendicular to the third direction f3, and both the second direction f2 and the third direction f3 may be perpendicular to the first direction f1.

[0062] In the embodiments of the present application, Figure 5As shown, in the case where the first sliding stopper 300 includes the first sub-stopper 301 and the second sliding stopper 400 includes the third sub-stopper 401, the first sub-stopper 301 can be fixed on the side of the first support plate 102a facing the second mirror group body 201, and the third sub-stopper 401 can be fixed on the side of the second mirror group body 201 facing the first support plate 102a. In this case, by fixing the first sub-stopper 301 in the first sliding stopper 300 on the side of the first support plate 102a facing the second mirror group body 201, the third sub-stopper 401 in the second sliding stopper 400 is fixed on the side of the second mirror group body 201 facing the first support plate 102a. In this way, during the assembly of the second mirror group 200 and the first mirror group 100, the first sub-limiting member 301 and the third sub-limiting member 401 cooperate with each other as installation positioning members between the second mirror group body 201 and the support portion 102, so that the second mirror group body 201 can be quickly assembled to the support portion 102 along the second direction f2, and finally the assembly of the second mirror group 200 and the first mirror group 100 is completed.

[0063] In this application, if Figure 4 As shown, when the first sliding limit member 300 includes a second sub-limit member 302 and the second sliding limit member 400 includes a fourth sub-limit member 402, the second sub-limit member 302 can be fixed on the side of the first mirror group body 101 facing the sliding connection part 202, and the fourth sub-limit member 402 can be fixed on the side of the sliding connection part 202 facing the first mirror group body 101.

[0064] In the examples of this application, please refer to Figure 6 , Figure 6 It is an exploded schematic diagram of another camera module provided in an embodiment of the present application. One of the first sub-limiting member 301 and the third sub-limiting member 401 can be a first slide groove A1, and the other of the first sub-limiting member 301 and the third sub-limiting member 401 can be a first limit column A2 that cooperates with the first slide groove A1. Among them, the extension direction of the first slide groove A1 can be parallel to the first direction f1, and at least a portion of the first limit column A2 can be located in the first slide groove A1. And / or, one of the second sub-limiting member 302 and the fourth sub-limiting member 402 can be a second slide groove B1, and the other of the second sub-limiting member 302 and the fourth sub-limiting member 402 can be a second limit column B2 that cooperates with the second slide groove B1. Among them, the extension direction of the second slide groove B1 can be parallel to the first direction f1, and at least a portion of the second limit column B2 can be located in the second slide groove B1.

[0065] For example, one of the first sub-limiting member 301 and the third sub-limiting member 401 may be a first slide groove A1, and the other of the first sub-limiting member 301 and the third sub-limiting member 401 may be a first limit post A2. For example, the first sub-limiting member 301 may be a first slide groove A1, and the third sub-limiting member 401 may be a first limit post A2; or, the first sub-limiting member 301 may be a first limit post A2, and the third sub-limiting member 401 may be a first slide groove A1. In this way, through the cooperation and sliding of the first sub-limiting post A2 and the first slide groove A1, the second mirror group 200 is prevented from having an excessive sliding stroke relative to the first mirror group 100 along the first direction f1. For example, one of the second sub-limiting member 302 and the fourth sub-limiting member 402 may be a second slide groove B1, and the other of the second sub-limiting member 302 and the fourth sub-limiting member 402 may be a second limit post B2. For example, the second sub-limiting member 302 may be a second sliding groove B1, and the fourth sub-limiting member 402 may be a second limiting column B2; or the second sub-limiting member 302 may be a second limiting column B2, and the fourth sub-limiting member 402 may be a second sliding groove B1. In this way, through the cooperation and sliding of the second sliding groove B1 and the second limiting column B2, it is also possible to prevent the second mirror group 200 from having an excessive sliding stroke relative to the first mirror group 100 along the first direction f1.

[0066] Optional, such as Figure 5 and Figure 6 As shown, in the case where a first slide groove A1 is provided on the first mirror group body 101 and a second slide groove B1 is provided on the second mirror group body 201, the length of the first slide groove A1 and the length of the second slide groove B1 can be equal, and both can be less than the maximum distance that the second mirror group body 201 slides relative to the first mirror group body 101. Here, by setting the length of the first slide groove A1 on the first mirror group body 101 and the length of the second slide groove B1 on the second mirror group body 201 to be equal, and both to be less than the maximum distance that the second mirror group body 201 slides relative to the first mirror group body 101, after the second mirror group body 201 moves to the maximum distance relative to the first mirror group body 101, the ends of the two slide grooves can respectively cooperate with the two limiting columns to limit the second mirror group body. It should be noted that the maximum distance that the second mirror group body 201 slides relative to the first mirror group body 101 needs to be less than the length of the support portion 102 in the first mirror group 100 along the first direction f1. That is, even after the second mirror group body 201 slides to the maximum distance relative to the first mirror group body 101 , the second mirror group body 201 is still located on the support portion 102 , ensuring that the second mirror group body 201 and the support portion 102 will not be separated.

[0067] In the examples of this application, please refer to Figure 7 , Figure 7000 is an exploded schematic diagram of a camera module provided by another embodiment of the present application. The camera module 000 may also include: a photosensitive chip 500 and a reflective element 600. The photosensitive chip 500 may be located on the side of the second lens group 200 away from the first lens group 100. The reflective element 600 may be located on the side of the first lens group 100 away from the second lens group 200, and the reflective surface m1 of the reflective element 600 may face the first lens group 100. Among them, the optical axis of the first lens group 100 and the optical axis of the second lens group 200 may both coincide with the central axis of the photosensitive chip 500. For example, the reflective element 600 may be a prism or a reflector, and the reflective surface of the prism or the reflective surface of the reflector may be coated with a metal film layer, which may avoid color deviation and halo phenomenon during imaging, so that the lens can improve color deviation and effectively concentrate the point light source to obtain good imaging quality.

[0068] In this application, if Figure 7 As shown, the camera module 000 may also include: a circuit board 800, a photosensitive chip 500 may be fixed on the circuit board 800 and electrically connected to the circuit board 800, and a photosensitive surface of the photosensitive chip 500 may face the second lens group 200. For example, the camera module 000 in the implementation of the present application may be installed in an electronic device when the electronic device takes a photo. First, the light reflected from the surface of an external object can be transmitted to the photosensitive chip in the camera module 000 through the multiple lens groups in the camera module 000. The photosensitive chip 500 can sense and collect the light reflected from the surface of an external object, and generate corresponding image information. Afterwards, the circuit board in the camera module can transmit the image information generated by the photosensitive chip to an electronic device having this camera module, so that the corresponding image can be presented on this electronic device.

[0069] Optional, such as Figure 7 As shown, the camera module 000 may further include: a third lens group 700 located between the reflective element 600 and the first lens group 100, and the first lens group 100 can drive the second lens group 200 to move synchronously relative to the third lens group 700. Here, when the first lens group 100 in the camera module drives the second lens group 200 to move synchronously, the zoom function of the camera module can be realized, and the second lens group 200 can slide relative to the first lens group 100, so that the camera module can realize the focusing function.
