Abstract

The invention discloses a damping hinge, a folding mechanism and electronic equipment. The damping hinge comprises an outer shaft which is hollow; an inner shaft provided with an inner cavity, wherein the inner shaft is rotatably arranged in the outer shaft, an outer cavity is formed between the inner shaft and the outer shaft, liquid is arranged in the outer cavity and the inner cavity, and a through hole suitable for communicating the outer cavity with the inner cavity is formed in the inner shaft; and a piston movably arranged in the inner cavity, wherein the piston is used for blocking or opening the through hole so as to adjust the damping of relative rotation of the outer shaft and the inner shaft.

Description

technical field [0001] The application belongs to the technical field of electronic equipment, and in particular relates to a damping hinge, a folding mechanism and electronic equipment. Background technique [0002] Folding screen mobile phones can expand the display area of ​​the screen and have been widely used. The important part of the folding screen mobile phone is the hinge. The function of the hinge is to assist in the folding of the folding screen, and to take into account the stability and durability of the folding screen when it is bent. It is regarded as the core technology of the folding screen mobile phone. However, in the process of folding and unfolding, the strength of the hinge is difficult to control, or it is too loose, so that the folding screen is easy to automatically switch from the unfolded state to the folded state under the force of gravity, or automatically switch from the folded state to the unfolded state, and the folded Between the state and ...
