AI Technical Summary

Technical Problem

Current hinge mechanisms in foldable electronic devices are large in size, making it difficult to meet the design requirements of miniaturization and thinness, and they pose a risk of pulling or squeezing the flexible display screen during unfolding and closing.

Method used

A hinge mechanism with a main shaft and rotating assemblies, including first and second rotating components, that utilize gear meshing and pull rods to synchronize the movement of shell fixing frames, reducing the size of the hinge mechanism and minimizing the risk of screen deformation.

Benefits of technology

The mechanism reduces the size of the hinge mechanism, enhances the reliability of the flexible display screen by minimizing the risk of pulling or arching, and simplifies the structural composition while maintaining synchronization during unfolding and closing.

Abstract

The invention discloses a rotating shaft mechanism and electronic equipment, and aims to reduce the size of the rotating shaft mechanism and improve the reliability of a flexible display screen of the electronic equipment. The rotating shaft mechanism comprises a main shaft, a first rotating assembly, a second rotating assembly, a first shell fixing frame and a second shell fixing frame, the first rotating assembly comprises a first gear shaft, a first gear connecting rod, a first rotating piece and a first pull rod, the first gear shaft comprises a first rotating shaft and a first gear, and the first rotating shaft is rotationally arranged on the main shaft; the first gear connecting rod comprises a first connecting rod and a second gear, the first connecting rod is slidably connected with the first shell fixing frame, and the second gear is meshed with the first gear; the first rotating piece is fixedly connected with the first rotating shaft; the first pull rod is rotationally connected with the first rotating piece and the first shell fixing frame. In the unfolding or closing process of the electronic equipment, the first rotating piece rotates along with the first rotating shaft and drives the first pull rod to move towards the side close to or away from the second shell fixing frame.
