Title:
ROTARY SHAFT MECHANISM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/115462
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronic devices. Provided are a rotary shaft mechanism and an electronic device. The rotary shaft mechanism comprises a main shaft assembly and two folding assemblies, which are symmetrically arranged relative to the main shaft assembly; and the two folding assemblies can rotate in a direction facing each other or in a direction away from each other relative to the main shaft assembly. When the folding assemblies are specifically configured, each of the folding assemblies comprises a rotary assembly, a supporting plate and a shell-fixing frame, wherein the rotary assembly is rotationally connected to the main shaft assembly, and the supporting plate is rotationally connected to the shell-fixing frame and is slidably connected to the rotary assembly. By using the rotary shaft mechanism, in the relative rotation process of two shell-fixing frames, two supporting plates rotate in the same direction relative to the shell-fixing frames on corresponding sides, so that the two supporting plates and the main shaft assembly can form a screen-accommodating space similar to a triangle shape, and when the electronic device is in a closed state, the screen-accommodating space can be used for accommodating a bent portion of a flexible screen, such that the flexible screen can be prevented from being damaged by means of pressing, and the service life of the flexible screen can be prolonged.
