AI Technical Summary

Technical Problem

Existing hinge mechanisms occupy a large space in foldable screen devices, hindering the miniaturization of these devices.

Method used

The device employs a rotating shaft assembly, including a positioning seat, a rotating component, and a support component. The rotating component and the driven component are directly connected to the positioning seat, and the rotating component and the driven component are slidably connected. The side support component is movably connected to the positioning seat, thereby enabling folding or unfolding.

Benefits of technology

The overall width of the rotating shaft assembly is reduced, saving internal space, facilitating the layout of other components, lowering manufacturing costs, and improving the compactness and reliability of the connection.

Abstract

The application provides a rotating shaft device, which comprises a positioning seat, a rotating assembly and a supporting assembly. The positioning seat comprises a connecting part arranged at the end thereof. The rotating assembly comprises a first rotating mechanism and a second rotating mechanism. The first rotating mechanism and the second rotating mechanism each comprise a rotating piece and a driven piece. The rotating pieces of the two rotating mechanisms are rotatably connected with the connecting part respectively. The driven pieces of the two rotating mechanisms are rotatably connected with the positioning seat respectively. The driven piece and the rotating piece of the first rotating mechanism are slidably connected. The driven piece and the rotating piece of the second rotating mechanism are slidably connected. The supporting assembly comprises two side supporting pieces. The two side supporting pieces are rotatably connected with the rotating piece of the first rotating mechanism and the rotating piece of the second rotating mechanism respectively. The two side supporting pieces are movably connected with the positioning seat respectively. The application also relates to a folding shell provided with the rotating shaft device and an electronic device.
