By the cooperation of the limiting protrusion 174 and the limiting groove 125, the movement of the connecting member 17 along the axial direction of the through hole 121 to the second decorative ring 16 is restricted, and since the connecting member 17 is fixedly connected with the second decorative ring 16, it is also avoided. The second bezel 16 is further away from the housing 12. Referring to FIGS. 3 and 6, in the embodiment of the present invention, the limiting slot 125 is in communication with the through hole 121, and the connecting wall 173 passes through the through hole 121. One end of the connecting wall 173 is connected to the body 172, and the other end is connected to the limiting protrusion 174. The shape of the body 174 may be in the shape of a racetrack. The connecting wall 173 is respectively connected to the upper edge, the lower edge, the left edge and the right edge of the body 174. Correspondingly, the limiting protrusion 174 is located on the upper side, the lower side and the left side of the body 174. And the right side, so that when the limiting protrusion 174 is engaged with the limiting groove 125, the connecting member 17 is relatively evenly stressed.

In some embodiments, the number of the through holes 121, the first through holes 141, the second through holes 161, and the third through holes 171 are all single.

Correspondingly, the number of lenses in the camera module 300 is single, and a single lens passes through the through holes 121, the third through holes 171, the first through holes 141, and then penetrates into the second through holes 161.

Referring to FIG. 2 and FIG. 6 , in some embodiments, the number of the through holes 121 is single, and the number of the first through holes 141 , the second through holes 161 , and the third through holes 171 is two.

The size and shape of the two first through holes 141 may be equal. For example, the two first through holes 141 are all circular, square, triangular, etc., so that the molds for manufacturing the two first through holes 141 may be the same. , saving manufacturing costs. Of course, according to actual needs, the size and shape of the two first through holes 141 may not be completely equal. For example, when the sizes of the camera modules 300 corresponding to the two first through holes 141 are inconsistent, in order to adapt to the camera. The size of the module 300 may be different, and the sizes of the two first through holes 141 may also be different. Similarly, the size and shape of the two second through holes 161 and the two second through holes 171 are similar to the two first through holes 141, and details are not described herein.

Correspondingly, the number of camera modules 300 may be two, and each camera module 300 is installed corresponding to one first through hole 141. Specifically, the optical axis of each camera module 300 coincides with the axis of the corresponding one of the first through holes 141. The two camera modules 300 can be controlled by the processor of the mobile terminal 1000 to provide a better user experience.

Specifically, in one example, two camera modules 300 can be simultaneously imaged to optimize imaging quality. For example, two camera modules 300 simultaneously image a multi-frame first image and a multi-frame second image. The processor of the mobile terminal 1000 can analyze and filter the multi-frame first image and the multi-frame second image to select a frame image with the best image quality as the final image. Alternatively, the processor combines or stitches the first image and the second image to achieve enhancement of color or sharpness of the final image.

In another example, one camera module 300 can be used to assist in imaging another camera module 300 to optimize image quality. For example, one camera module 300 first detects the brightness of the current scene, and the processor analyzes the detected brightness values to control the exposure time of the photosensitive elements corresponding to each pixel in the other camera module 300 to obtain an image of suitable brightness. In this way, it is ensured that the finally obtained image does not have the problem of overexposure or low brightness, and the quality of the image acquired by the camera module 300 is improved.

In yet another example, the two camera modules 300 can be turned on sequentially for imaging to optimize image quality. For example, one camera module 300 employs a wide-angle lens and the other camera module 300 employs a telephoto lens. When imaging is required, the camera module 300 using the wide-angle lens is first turned on for imaging. If the mobile terminal 1000 detects that the user performs the zoom-in operation of the preview image, and the magnification ratio exceeds the preset value, the camera module with the telephoto lens is immediately turned on. Group 300 is imaged. In this way, since the wide-angle lens has a large field of view and a short focal length, the telephoto lens has a small field of view and a large focal length. When the user performs a preview image enlargement operation, the user wants to take a distant scene, and the telephoto is used at this time. The lens is capable of capturing a clear perspective, and therefore, switching to the camera module 300 using the telephoto lens for imaging to enhance the sharpness of the acquired image.
