Balance control mechanism, folding display device and communication equipment

Abstract

A balance control mechanism, comprising a pair of fixed seats respectively located on the outermost side, a pair of rotating seats respectively located inside the pair of fixed seats, first and second clamping seats and clamping seats located between the pair of rotating seats The transmission assembly held between the first and second clamping seats, the rotating seat includes a seat body, an arc-shaped groove opened on the seat body, and a lateral direction from the bottom of the arc-shaped groove of the seat body Extended tooth structure; the present application also provides a foldable display device and a communication device.

Description

technical field [0001] This application relates to the field of communication electronics, especially to a balance control 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] Moreover, the current folding mechanism used to connect two folding screens for folding is very complicated in structure, and a ...

AI Technical Summary

Problems solved by 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] Moreover, the current folding mechanism used to connect two folding screens for folding is very complicated in structure, and a small folding mechanism even reaches hundreds of components assembled together. It will inevitably lead to an increase in the instability of the organization, which is also one of the main reasons why the current folding screen mobile phone cannot be launched in large quantities.
