Rotating shaft mechanism and electronic device

Abstract

A rotating shaft mechanism, comprising: a fixed assembly 310, a rotating assembly 320, and a supporting assembly 330. The rotating assembly 320 comprises: rotary members 321 and rotating members 322 rotatably connected to the fixed assembly 310, and fixing supports 323 respectively slidably connected to the rotary members 321 and the rotating members 322; the rotating shaft direction of the rotary members 321 is parallel to the rotating shaft direction of the rotating members 322, and the sliding directions of the fixing supports 323 on the rotary members 321 and the rotating members 322 are not parallel; the supporting assembly 330 comprises: side plates 332 respectively rollingly connected to the rotary members 321 and the rotating members 322, the rotary members 321 and the rotating members 322 are located on the same side of the side plates 332, the fixing supports 323 are rotatably connected to the side plates 332, and the rotating shaft direction of the side plates 332 is parallel to the rotating shaft direction of the rotary members 321; the rotary members 321, the rotating members 322, the fixing supports 323 and the side plates 332 are linked. The rotating shaft mechanism limits slide strokes of the rotating members and the fixing supports by means of the rolling connection between the rotary members and the side plates, so as to improve the motion stability of the rotating shaft mechanism.
