U-shaped inward-folding rotating mechanism straight sliding groove bending

Abstract

The invention discloses a U-shaped inward-folding rotating mechanism for straight sliding groove bending. The mechanism comprises a structure body; the structure body comprises two sets of rotating shafts; each rotating shaft comprises a rotating mechanism body; each rotating mechanism body comprises a first fixed frame and a second fixed frame; the first fixed frames and the second fixed frames are longitudinally distributed side by side; first rotating frames and second rotating frames which are transversely and symmetrically distributed are arranged between the first fixed frames and the second fixed frames; arc-shaped sliding grooves which are rotationally connected and two sets of symmetrically distributed fixed frame sliding columns are arranged on the opposite inner side edges of the first fixed frames and the second fixed frames respectively; straight sliding grooves and rotating frames sliding columns which are rotationally connected are respectively arranged at the rotationaljoints between the first rotating frames as well as the second rotating frames and the first fixed frames as well as the second fixed frames; the fixed frame sliding columns are in sliding fit with the interiors of the straight sliding grooves; and meanwhile the rotating frame sliding columns are in sliding fit with the interiors of the arc-shaped sliding grooves, that is, the straight sliding grooves limit the motion trail of the first rotating frames and the motion trail of the second rotating frames to achieve 0-180-degree bending rotation.

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 U-shaped inward-folding rotating mechanism with straight chute bending. 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 effec...

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.
