Damping mechanism, foldable hinge and electronic device

Abstract

The invention relates to the field of foldable display devices, and discloses a damping mechanism, a foldable hinge and an electronic device. The damping mechanism comprises bases with limiting grooves, damping shafts arranged in the limiting grooves in a penetrating mode, synchronous connecting plates fixed at one ends of the damping shafts and used for providing rotating force for the damping shafts, sliding blocks capable of moving in the axis directions of the damping shafts and rotationally arranged on the damping shafts in a sleeving mode along with the damping shafts, and elastic parts;the sliding blocks abut against the inner walls of the limiting grooves, and damping teeth are arranged on the contact faces of the sliding blocks and the inner walls of the limiting grooves correspondingly; when the damping shafts rotate, tooth peaks of the inner walls of the limiting grooves make contact with tooth peaks of the sliding blocks, or tooth valleys of the inner walls of the limitinggrooves make contact with tooth peaks of the sliding blocks; and the elastic parts are arranged in the limiting grooves and abut against the ends, deviating from the inner walls of sliding grooves, of the sliding blocks, and the elastic parts are in a compressed energy storage state so that the sliding blocks can abut against the inner walls, with the damping teeth, of the limiting grooves. According to the damping mechanism, the effect that the synchronous connecting plates hover at any position can be achieved through the friction force.

Description

technical field [0001] The invention relates to the technical field of foldable display devices, in particular to a damping mechanism, a folding hinge and an electronic device. Background technique [0002] With the development of smart electronic devices and the change of users' functional requirements for electronic devices, foldable electronic devices have become high-end smart products deployed by major electronic device manufacturers. Folding electronic devices can provide users with larger screens, more novel operating experience, more portability, and a better sense of technology. [0003] At present, the existing folding electronic devices on the market have basically solved the basic folding function of the folding electronic devices. The characteristic of the folding electronic devices on the market is to use the folding shaft to realize the inward folding and outward folding of the screen, so as to realize the expansion of the screen. However, the current folding...
