AI Technical Summary

Technical Problem

Traditional flexible screen display devices are prone to screen dent problems after long-term use, and the elastic driving parts cannot effectively provide support along the thickness direction of the flexible screen in the flattened state, resulting in the screen being easily depressed.

Method used

A support flattening mechanism including a rotating structural member, a screen support member and a plurality of opening and closing tension driving components is adopted. The mechanism switches the support flattening mechanism from the winding state through the rigid driving effect of the opening and closing tension driving component. To the flattened state, the flexible screen can be automatically expanded and the stability is maintained in the flattened state.

Benefits of technology

It effectively avoids the collapse of the display device screen, improves the stability and controllability of the flexible screen after flattening, and ensures the high controllability and stability of the structure.

Abstract

The embodiment of the invention provides a supporting and flattening mechanism of a flexible screen, a hinge and display equipment. The supporting and flattening mechanism is applied to the flexible electronic equipment, and the supporting and flattening mechanism has a winding state and a flattening state which can be mutually converted. The supporting and flattening mechanism comprises a rotating structural part, a screen supporting part and a plurality of opening and closing tensioning driving assemblies. The rotating structural part comprises a plurality of first rotating connecting parts and second rotating connecting parts which are alternately connected; the multiple opening and closing tensioning driving assemblies are correspondingly arranged on the multiple second rotating connecting pieces, and the opening and closing tensioning driving assemblies are rigidly connected with the first rotating connecting pieces in an abutting mode so as to change the included angles between the first rotating connecting pieces and the second rotating connecting pieces; the screen supporting piece is connected with the rotating structural piece, and the side, opposite to the rotating structural piece, of the screen supporting piece is configured to be covered with a flexible screen. Therefore, the supporting and flattening mechanism provided by the embodiment of the invention has the advantages of high controllability and high structural stability.
