Passive drop-shaped two-side synchronous rotating mechanism

The invention is a divisional application of an invention patent with the application number of 201910595711.0, and the original patent name is: the application date of the passive drop-shaped synchronous rotating mechanism on two sides is as follows: 7.3.2019.

Technical Field

The invention relates to the technical field of rotating shaft design, in particular to an inward-folding connecting shaft, and particularly relates to a passive drop-shaped two-side synchronous rotating mechanism.

Background

Folding screen refers to flexible OLED. The production of the folding screen is not only greatly beneficial to the manufacture of new generation high-end smart phones, but also has profound effects on the application of wearable equipment due to the low power consumption and the flexible characteristic of the folding screen, and the folding screen is widely applied along with the continuous penetration of personal intelligent terminals in the future. 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.
