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

A folding mechanism comprises a rotating mechanism, at least one pair of fixing bases located on the two transverse sides of the rotating mechanism respectively, and transmission mechanisms connectedwith the rotating mechanism and the fixing bases. The rotating mechanism is supported on the fixing bases through at least two transmission mechanisms; the rotating mechanism is in a suspended state;the rotating mechanism comprises a pair of main shafts and a pair of gears which are arranged on the pair of main shafts in a sleeving mode respectively and meshed with each other; a fixed shaft is arranged on each fixing base; each transmission mechanism comprises a fixed end fixed to the main shaft, a sliding end and a connecting part for connecting the fixed end with the sliding end; the sliding end is provided with an arc-shaped rail moving around the fixed shaft; when the fixing bases are pulled to move relatively, the transmission mechanisms are driven to further drive the pair of main shafts to rotate reversely, and the pair of gears effectively control the balance of rotation of the pair of main shafts. The invention further comprises 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...
