Arc infolding rotating mechanism with invariable tangent point

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...

Problems solved by technology

[0003] To achieve the above technical effects, the biggest technical problem is directly transferred from the design of the screen to the design technology of the rotating shaft. How to realize the inward folding requires a special rotating mechanism, not only considering the possibility of rotating and folding, but also the effective bilateral connection. In particular, it is necessary to meet the problem of bending synchronization. The traditional inward-folding flexible screen shaft is inconvenient and industrialized due to the large number of parts and components.
