Synchronous rotating mechanism for inward and outward folding of flexible screen

Abstract

The invention discloses a synchronous rotating mechanism for inward and outward folding of a flexible screen. The mechanism comprises three rotationally connected cases and rotary mechanisms for connecting the cases, wherein the rotary mechanisms include an outward-folding rotary mechanism and an inward-folding rotary mechanism; the inward-folding rotary mechanism comprises an inward-folding package body and an inward-folding rotary shaft; the inward-folding rotary shaft comprises an inward-folding moving frame, a sliding moving frame and a compensation moving frame, and the sliding moving frame and the compensation moving frame are bilaterally symmetrically arranged, combined and connected; the sliding moving frame comprises a first sliding moving frame body and a second sliding moving frame body; two slots are formed in the inward-folding moving frame; a sliding groove, a sliding block and a sliding post are arranged on each of the first sliding moving frame body and the second sliding moving frame body; each sliding post can slide in the corresponding slot, the corresponding sliding groove and the corresponding sliding block; the sliding posts can rotate in the corresponding slots to be flattened, upward and downward movement is realized, and accordingly, the condition that the mechanism jacks the screen is avoided; clamping point grooves are combined with corresponding positioning pins, so that a clamping point self-locking function is available in both 0-degree and 180-degree states; each sliding groove and the corresponding sliding post are in sliding connection and achieve semi-arc locking synchronization, and a compensation function is achieved in a screen unfolding state.

Description

technical field [0001] The invention relates to the technical field of double-folding design of flexible screens, in particular to a double-folding connecting shaft, in particular to a synchronous rotation mechanism of inside and outside double-folding of flexible screens. Background technique [0002] Folding screen, refers to flexible OLED. The successful mass production of folding screens is not only a major benefit 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 bendable characteristics. The continuous penetration of the terminal is widely used. A folding screen mobile phone refers to a mobile phone with a bendable and flexible screen. Because it looks like a mango roll, it is also called a roll mango phone. Compared with the traditional screen, the folding screen has obvious advantages. It is not only lighter and thinner in size, but also has lowe...

Problems solved by technology

Considering the particularity of folding screens, traditional hinges cannot meet their functional requirements, and special hinges for folding screens are needed to assist in realization. According to application requirements, folding screens can be divided into two types of bending requirements: outward folding and outward folding. To further realize the large-size application of flexible screens, two or more sets of rotating mechanisms can be used at the same time to achieve multi-folding requirements, that is, the double-folding functions of internal folding and external folding can be used at the same time
