Folding screen handsets are those that employ a flexible, flexible screen because they resemble a scroll, also known as a scroll handset. Compared with the traditional screen, the folding screen has obvious advantages, is lighter in size and lighter in power consumption, is lower than the original device, is favorable for improving the endurance capacity of equipment, and is also higher than the traditional screen greatly in durability based on the characteristics of being bendable and good in flexibility, so that the probability of accidental damage of the equipment is reduced.
In order to realize the folding function of the folding screen, besides the screen, the design of a connecting shaft of a folding connecting assembly, namely a bending part, is also the biggest technical problem. Considering the specificity of folding screen, traditional pivot has not had to satisfy its functional requirement, needs special folding screen pivot to assist the realization, and folding screen is bent and is divided into two kinds of demands of bending of outer book and outer book according to the application demand, and the mechanism of bending of inner book its requirement is higher. Especially considering to use with flexible screen combination, flexible screen has its specificity, and the industrialization processing of pivot itself also has certain degree of difficulty, and the precision requirement of its accessory is high, how to simplify the processing degree of difficulty just can realize industrialization when satisfying flexible screen application.
In the bending and rotating process of the flexible screen, how to ensure auxiliary synchronization and meet the precision requirement, especially abnormal sound cannot exist, and the service life stability is required to be met.
