A synchronous rotating mechanism based on concentric shaft outward folding

Abstract

The invention discloses a synchronous rotating mechanism based on concentric shaft outward folding. Structural main body consists of a shell, a packaging body, and a double-side rotating shaft connected with the shell; the rotating shaft consists of a concentric shaft and a compensation mechanism. The concentric shaft is composed of a first section shaft, an intermediate movable frame and a secondsection shaft which are coaxially connected in a center,; the middle movable frame is connected with the first section shaft and the second section shaft, the first section shaft and the second section shaft are reversely and symmetrically distributed and are of the same structure, the concentric shaft takes the shaft core as a central point; the first section shaft, the middle movable frame andthe second section shaft rotate around the central point, and the arc length and the chord length of a rotating track are kept unchanged in the rotating process; The first section shaft and the secondsection shaft are composed of a gear shaft, a gear, a round body and a plurality of sets of movable components, which are connected in a combined manner., the two sides of the middle movable frame are connected with clamping point blocks for achieving 180-degree flattening clamping point positioning; the gear shaft and the rack coaxially rotate, the semicircular pipe position meets the bending requirement of outward bending, bending is achieved through integrated packaging and rotating, the design is reasonable, and the modeling design is simple and convenient.

Description

technical field [0001] The present invention relates to the technical field of folding screen applications, in particular to a connecting shaft for folding screen applications, in particular to a synchronous rotating mechanism based on outward folding of concentric shafts. Background technique [0002] Folding screen refers to flexible OLED. The successful mass production of folding screens is not only beneficial to the manufacture of a new generation of high-end smartphones, but also has a profound impact on the application of wearable devices due to its low power consumption and bendability. In the future, folding screens will follow the trend of personal smart phones. Terminal penetration and wide application. Folding screen mobile phone refers to a mobile phone with a bendable and flexible screen. Because it looks like a mans roll, it is also called a mans roll phone. Compared with traditional screens, folding screens have obvious advantages. Not only are they thinner ...

AI Technical Summary

Problems solved by technology

Considering the particularity of folding screens, traditional hinges cannot meet its functional requirements, and special hinges for folding screens are needed to assist in the realization. According to application requirements, folding screens can be divided into two types: outer folding and outer folding. The bending mechanism has higher requirements
