Abstract

The invention discloses an arc infolding rotating mechanism with an invariable tangent point. The arc infolding rotating mechanism comprises a rotating shaft; the rotating shaft comprises a rotating mechanism; the rotating mechanism comprises two rotating frames which are transversely distributed; an arc groove movable block and two arc sliding blocks which are longitudinally distributed and rotationally connected are arranged between the rotating frames; arc sliding grooves glidingly connected with the arc sliding blocks are formed in the two sides of the arc groove movable block; the arc sliding blocks slide in the arc sliding grooves in a reciprocating mode to achieve U-shaped inward-bending rotation with the tangent point of a 0-180-degree motion trail unchanged; the rotating frames and the arc groove movable block rotate through sliding fit of a sliding column and a curved groove; rotating holes are formed in the rotating frames; rotating columns are arranged on the arc sliding blocks; and the rotating frames and the arc sliding blocks are rotationally connected through running fit of the rotating columns and the rotating holes.

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 circular-arc inward-folding rotation mechanism with a constant tangent point. Background technique [0002] At present, whether it is a tablet, a mobile phone or other electronic products with a display screen, they are all developing in the direction of a flexible screen. In the development process of this technical field, transitional products with functions similar to the flexible screen are also indispensable. The so-called transition The product is to achieve double-screen folding, and achieve the effect of full-screen folding through double-screen folding. In the process of bending, there is no obvious flaw, and the overall effect of full-screen folding is given to people. This method is used to test or give feedback. Consumer attitudes towards screen folding usage. [0003] To achieve the above technical...
