Background technique

With the improvement of user requirements, the terminal device is usually equipped with a front camera and a rear camera, and the front camera and the rear camera can respectively shoot towards the front and rear sides of the terminal device. The front camera can realize the user's selfie; the rear camera can realize the user's long-distance shooting, and usually, the number of rear cameras is at least two, so as to meet the user's shooting needs at different distances.

The screen-to-body ratio of current terminal devices is increasing. In order to increase the screen-to-body ratio of terminal devices, more and more terminal devices design their front cameras as elevating front cameras. When the user is shooting, the user can control the front camera to move outside the housing of the terminal device; after the user finishes shooting, the user can control the front camera to move into the housing of the terminal device, thereby realizing the hide.

In order to improve the space occupied by each camera after assembly, the current front camera and rear camera are distributed one by one in the moving direction of the front camera. This setting method will occupy a large space in the moving direction of the front camera. As the thickness of the terminal device becomes smaller and smaller, the front camera and the rear camera will form a convex hull 102 higher than the battery cover 101 . The arrangement of the above-mentioned front camera and rear camera makes the length D of the convex hull 102 larger, as shown in FIG. 1 . A longer convex hull 102 results in poorer appearance performance of the terminal device.
