A rotating shaft mechanism and electronic device

Abstract

The application provides a rotating shaft mechanism and an electronic device. The rotating shaft mechanism comprises a base and a main shaft module. The main shaft module comprises two rotating assemblies. Each rotating assembly comprises a support arm, a swing arm and a housing fixing frame. The two support arms are arranged on the two sides of the base and are rotationally connected with the base. The two swing arms are arranged on the two sides of the base and are rotationally connected with the base. The rotation axes of the support arm and the swing arm on the same side of the base are parallel and do not coincide. The two housing fixing frames are arranged on the two sides of the base. Each housing fixing frame is provided with two sliding grooves. For the support arm, the swing arm and the housing fixing frame on the same side of the base, the support arm and the swing arm can slide in a sliding groove respectively. In a reference plane perpendicular to the rotation axes of the support arm and the swing arm, the projections of the sliding directions of the support arm and the swing arm are not parallel. By using the rotating shaft mechanism, the reliability of the structure of the electronic device can be ensured, and a screen accommodating space meeting the bending requirements of the flexible display screen can be formed, so as to reduce the risk of damage of the flexible display screen.
