Hinge mechanism for folding screen and mobile terminal

Abstract

The invention relates to a hinge mechanism for a folding screen and a mobile terminal. The hinge mechanism comprises a hinge mounting seat, a plurality of hinge devices are mounted on the hinge mounting seat in the extension direction of the hinge mounting seat, each hinge device comprises a mounting base, and a left overturning assembly and a right overturning assembly which are rotationally arranged on the mounting base and form synchronous overturning through an even number of gear sets, and sliding compensation and damping rotation are integrally designed on the left overturning assemblies and the right overturning assemblies. The structure is simple, the function integration is high, and the installation space can be effectively saved; and meanwhile, a better supporting effect can be provided when a flexible screen is in an unfolded state, a containing space can be provided for the overturning part of the flexible screen after the flexible screen is folded, and the damage to the flexible screen is reduced.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a hinge mechanism for a folding screen and a mobile terminal. Background technique [0002] With the continuous advancement and expansion of technology in the field of mobile terminals, coupled with the advent of the 5G network era, people are increasingly dependent on mobile terminals. Nowadays, with the continuous upgrading of various chat and video software, people feel that conventional touch-screen mobile phones or tablet computers are not enough. The main reason is that the size of the screen is limited by the size of the mobile terminal. [0003] In order to solve this problem, people invented the flexible screen and applied it to the mobile terminal. Through the folding design, the mobile terminal can not only meet people's requirements for carrying, but also expand the screen of the mobile terminal when needed. . In order to realize the above requirements, the key l...

AI Technical Summary

Problems solved by technology

At present, the hinge mechanism of mobile terminals using folding screens can have complex mechanical structures. In order to achieve synchronous flipping and damping feel in a limited space, it is often necessary to design different mechanical components to meet the requirements. At the same time, these mechanical components occupy a lot of installation space. The folding thickness of the mobile terminal using the folding screen is increased, and the thickness of the frame is large, etc.

At the same time, the existing mobile terminal with a folding screen will squeeze and stretch the flexible screen during the folding process. With long-term use, damage is likely to occur, especially at the folded part of the flexible screen.
