Multi-mode opening and closing drop-shaped inwardly-folding rotating mechanism

Abstract

The invention discloses a multi-mode opening and closing drop-shaped inwardly-folding rotating mechanism. According to the rotating mechanism, rotary shafts are arranged at the two ends of a rotary shaft cover, the rotary shafts are single-popup or double-lock opening and closing rotary shafts, and a strip-like groove and a connecting column which are in sliding connection with each rotary shaft are arranged at each of the two ends of the rotary shaft cover; each first movable block is provided with an outer side connecting column, a semicircle groove, an outer sliding groove and an inner sliding groove, and each second movable block is provided with an outer side connecting column, a semicircle groove, an outer sliding groove and an inner sliding groove; each first gear shaft is providedwith a concave wheel and a gear connecting rod, and each second gear shaft is provided with a concave wheel and a gear connecting rod; each middle movable block is provided with a column connecting rod and a middle sliding groove, the outer side connecting columns are in sliding connection with the strip-like grooves, the semicircle grooves are in sliding connection with the gear connecting rods,and the inner sliding grooves are in sliding connection with the column connecting rods; and the concave wheels and cams realize 0-degree and 180-degree clamping and self-locking through tooth form meshing, elastic force generated by springs and torsion, and automatically pop up to a 180-degree flattened state after being opened at 0 degree, functional adjustment of single-popup or double-lock opening and closing of the rotary shafts is realized by changing the tooth form meshing angles of the concave wheels and the cams, and either popup or closing is selected during double-lock opening and closing.

Description

technical field [0001] The invention relates to the technical field of rotating shaft design, in particular to an inwardly folded connecting shaft, in particular to a teardrop-shaped inwardly folded rotating mechanism with multi-mode opening and closing. 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 lower power consumption...

AI Technical Summary

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
