AI Technical Summary

Technical Problem

The damping mechanism in the prior art cannot take into account the lightweight design of electronic equipment and provide sufficient damping force, which affects the user's user experience.

Method used

A rotating shaft mechanism is adopted, the mechanism includes a first damping mechanism. The first damping mechanism simultaneously squeezes both ends of the first elastic body through a cam, increasing damping force, and reducing the space occupied by the damping mechanism by optimizing the design of the cam and the structure of the mating end surface.

Benefits of technology

While maintaining the lightweight design, the provision of damping force is increased, the user experience is improved, and the stability and reliability of the shaft mechanism are ensured.

Abstract

A rotating shaft mechanism (23), a folding assembly (20), and a foldable electronic device (100). The rotating shaft mechanism (23) comprises a first damping mechanism (234), the first damping mechanism (234) comprising a first rotating shaft (233), a first cam (2341), a first elastic body (2343), a first sliding block (2342) and a second sliding block (2344). The first cam (2341) has a first mating end surface (2341a) and a second mating end surface (2341b) which are disposed opposite to each other. The first elastic body (2343) is sleeved on the first rotating shaft (233). The first sliding block (2342) is slidably connected to the first rotating shaft (233), the first sliding block (2342) abuts against the end of the first elastic body (2343) facing away from the first cam (2341), and the first sliding block (2342) further comprises a third mating end surface (2342a) mated with the first mating end surface (2341a). The second sliding block (2344) is slidably connected to the first rotating shaft (233), the second sliding block (2344) is arranged between the first cam (2341) and the first elastic body (2343), and the second sliding block (2344) further comprises a fourth mating end surface (2344a) mated with the second mating end surface (2341b).
