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: outer folding and outer folding. The bending mechanism has higher requirements

Abstract

The invention discloses a circle-center-variable drop-shaped infolding gear rotating mechanism. The mechanism comprises a rotating shaft cover and rotating shafts arranged at the two ends of the rotating shaft cover, each rotating shaft comprises two sets of main movable blocks, and the main movable blocks are connected with a concave wheel connecting plate, center movable blocks, two sets of gearshafts, two sets of side edge movable blocks and two sets of cams, and a longitudinal sliding block is arranged at the lower bottom of each center movable block; the cams are provided with positioning grooves, a longitudinal sliding groove is formed in the lower bottom of the concave wheel connecting plate, flat position sliding grooves drive flat positions to rotate and synchronously slide, third connecting columns slide in transverse sliding grooves, second connecting columns rotate in side edge connecting holes, and first connecting columns slide in long track curve grooves to achieve compensation of the screen unfolding state; and a longitudinal sliding block and the longitudinal sliding groove are connected in a sliding manner to achieve positioning and auxiliary synchronization of the screen unfolding initial state, positioning grooves and positioning blocks are fixed to drive the cams to rotate, the cams and the concave wheel connecting plate are matched in a concave-convex manner to achieve clamping point self-locking in the 0-degree state and the 180-degree state, and torsion is generated to achieve rotation without abnormal sounds.

Description

technical field [0001] The invention relates to the technical field of rotating shaft design, in particular to an inward-folding connecting shaft, in particular to a drop-shaped inward-folding gear rotation mechanism with a variable center. 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 and thinner in size, but they als...
