Rotating Pop-Up Camera Mechanism for Full-Screen Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals, such as smartphones, face a low screen-to-body ratio due to camera placement, limiting display coverage and preventing automatic panoramic shooting since the camera can only shoot in a fixed direction.
Innovation Solution
A mobile terminal design featuring a shell with a mounting seat and camera assembly, driven by a transmission mechanism that allows the camera to extend and rotate, enabling exposure and concealment within an accommodation groove, allowing for both front and rear shooting modes and panoramic capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is placed on the side of the display screen to occupy space, then the camera can be integrated into the mobile terminal, but the coverage rate of the display screen on the front face decreases, resulting in a low screen-to-body ratio
Solution Approach 1:
The camera mounting seat is designed to be movable between an extended position (where the camera exposes from the shell for shooting) and a retracted position (where the camera is hidden in the accommodation groove). This dynamic positioning allows the display screen to cover the entire front face when the camera is retracted, while still enabling camera functionality when extended, thus resolving the contradiction between camera integration and display screen coverage area.
2Device complexity
If the camera is fixed in a certain direction, then the camera structure is simple, but the camera can only shoot in a fixed direction and cannot implement automatic panoramic shooting
Solution Approach 1:
The camera mounting seat enables the camera to rotate around a rotating shaft that is parallel to the first direction (the direction along which the accommodation groove extends). This rotational capability allows the camera to shoot in multiple directions and implement automatic panoramic shooting, while the rotation mechanism is integrated into the existing mounting structure, avoiding excessive complexity.
3Ease of operation
If the camera is always exposed from the shell, then the camera is always accessible for shooting, but the screen-to-body ratio is reduced and the display coverage is limited
Solution Approach 1:
The camera mounting seat is designed to move between extended and retracted positions along the first direction. When the camera needs to be used, the mounting seat extends to expose the camera from the shell, making it accessible for shooting. When the camera is not in use, the mounting seat retracts to hide the camera within the accommodation groove, allowing the display screen to cover the entire front face. This dynamic positioning resolves the contradiction between camera accessibility and display screen coverage area.

AI summary
The present disclosure relates to a transmission mechanism, a driving mechanism assembly, and a mobile terminal. The mobile terminal includes: a shell including a first mounting face and second mounting face opposite the first mounting, and a side face, the first mounting face defining an accommodation groove extending to the side face along a first direction; a camera mounting assembly, including a mounting seat and a camera, wherein the mounting seat is arranged in the accommodation groove; and a driving mechanism assembly, including a driver coupled to the shell and a transmission mechanism, the driver is movable to drive, by the transmission mechanism, the mounting seat to extend from the accommodation groove and capable of driving the mounting seat to rotate around a rotating shaft and the rotating shaft being parallel to the first direction.
