Damping hinge mechanism and folding type electronic device

Abstract

The invention provides a damping hinge mechanism comprising a connecting shaft, a torsion spring and a housing; the position of the housing is fixed; the torsion spring is spiral and is accommodated in the housing; the connecting shaft is inserted into the housing and passes through the torsion spring; the connecting shaft is fixed at the first end of the torsion spring, and the housing is fixed at the second end of the torsion spring; damping grease is arranged in the internal space of the housing; the connecting shaft can rotate relative to the housing. The damping hinge mechanism can be guaranteed to be automatically bounced off, can be used for controlling the bouncing-off speed, and is relatively simple in structure and relatively small in floor space, so that equipment can be slowly effectively opened in case of limited space, and relatively good user experience is realized. The invention further provides a folding type electronic device adopting the damping hinge mechanism.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a damping hinge mechanism and foldable electronic equipment using the damping hinge mechanism. Background technique [0002] With the rapid development of wireless communication technology and information processing technology, a variety of electronic devices have emerged as the times require. Products that are easy to carry and have a good user experience are popular, which requires that the products can be used in working conditions Folding technology is one of the more common implementation methods for perfectly realizing the function and being able to freely change the shape to reflect its portability, and the user experience of the product is also receiving more and more attention. [0003] The current automatic pop-up hinge is mainly realized by the elastic rotating shaft or torsion spring. The elastic rotating shaft is mainly realized by the cooperation of the...

Problems solved by technology

[0003] The current automatic pop-up hinge is mainly realized by the elastic rotating shaft or torsion spring, and the elastic rotating shaft is mainly realized by the cooperation of the spring and the concave-convex wheel, which has low conversion efficiency, poor stability and reliability; a single torsion spring can also realize automatic opening. Pop-up function, but there are certain requirements for assembly space

The above two methods can realize automatic pop-up, but the spring force is released instantly, the opening speed is very fast, and the user experience is poor

In order to solve the problem of speed, a damper can be added to reduce the speed on the basis of the elastic mechanism, but the structure is more complicated, and since the elastic mechanism and the damper are two separate parts, a large space is required to accommodate all the parts, and the space occupied is relatively large.
