Synchronizing mechanism, folding display device and communication equipment

Abstract

A synchronizing mechanism comprises first and second folding plates, a back cover, gear racks fixe to the back cover, fixing seats fixed to the first and second folding plates, sliding blocks limitedbetween the fixing seats and the folding plates, and gear sets limited on the gear racks; the first and second folding plates are each provided with a pair of fixing seats fixedly, and the sliding blocks are limited between the fixing seats; each fixing seat comprises a base fixed to the first folding plate or the second folding plate, a limiting part arranged on one side face of the base, and a limiting slot located on the side face of the base and below the limiting part; each sliding block comprises a sliding block main body, a limiting block extending toward the transverse outer side fromthe bottom surface of the sliding block main body and limited in the corresponding limiting slot, and damping blocks arranged on the two transverse side faces of the sliding block main body; and the side face of each limiting part is provided with at least two grooves. The application further provides a folding display device and communication equipment.

Description

technical field [0001] This application relates to the field of communication electronics, especially to a synchronous 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 does th...
