Folding mechanism, folding display device and communication equipment

Abstract

A folding mechanism, comprising a rotating mechanism, at least a pair of fixed seats respectively located on the lateral sides of the rotating mechanism, and a transmission mechanism connecting the rotating mechanism and the fixed seats, the rotating mechanism is supported by at least two transmission mechanisms On the fixed seat, the rotating mechanism is in a suspended state. The rotating mechanism includes a pair of main shafts and a pair of gears respectively sleeved on the pair of main shafts and engaged with each other. There is a fixed shaft, and the transmission mechanism includes a fixed end fixed to the main shaft, a sliding end, and a connecting portion connecting the fixed end and the sliding end, and the sliding end is provided with an arc track that moves around the fixed shaft, When the fixed seat is pulled to move relatively, it drives the transmission mechanism, and then drives the pair of main shafts to rotate in reverse, and the pair of gears effectively controls the balance of the rotation of the pair of main shafts; the application also includes a folding Display device and communication equipment.

Description

technical field [0001] The present application relates to the field of communication electronics, in particular to a folding mechanism, a folding display device and communication equipment. Background technique [0002] With the development of folding screen technology, folding screen mobile phones have become a hot technology. Although the folding screen can be bent, it still cannot be bent 180 degrees, and the bent part still needs to maintain a certain R angle, otherwise the screen will be damaged. The existing folding methods are divided into inner folding and outer folding, that is, the screen is folded inside or outside, such as the Mate X released by Huawei, which is outer folding, but the problem of outer folding is that the screen is exposed and easily scratched by hard objects Injury, and the folding screen is relatively fragile. [0003] Regardless of outward or inward folding, the problem to be solved is how to ensure that when the folding screen is bent, how d...
