Folding mechanism for flexible screen

Abstract

The invention discloses a folding mechanism for a flexible screen. The folding mechanism comprises an elastic thin plate and a bending joint assembly matched with the elastic thin plate, and more thanone group of synchronous sliding hinge mechanisms. The bending joint assembly comprises a plurality of joint units, each joint unit comprises a supporting framework, a lower side plate and an upper side plate, the tangent lines of the upper side plate and the lower side plate present a certain included angle, and when the lower side plates of the joint units are horizontally placed side by side,every two adjacent upper side plates are partially overlapped. Triangular limit blocks are installed on the two end faces of the joint units correspondingly, and each synchronous sliding hinge mechanism comprises a plurality of synchronous sliding hinge units which are hinged to each other. According to the folding mechanism for the flexible screen, by making design of the bending joint assembly similar to 'lobster joints', outer elastic thin sheets are attached to the outer side faces of the 'lobster joints', the fact that the joint units rotate around contact points is ensured, in the bending process, the inner and outer sides are bent synchronously and coaxially.

Description

technical field [0001] The invention relates to a folding mechanism, in particular to a folding mechanism for a flexible screen, and belongs to the technical field of folding mechanisms. Background technique [0002] A screen is a device used to display images and colors in electronic equipment. With the continuous development of science and technology, flexible screens are gradually used in current electronic devices. In order to meet people's growing requirements for small size and large screens of electronic devices, using flexible screens for foldable displays has become a research and development hotspot for current researchers. [0003] During the research and development process, the inventors of the present application found that when the foldable display is opened, it is often difficult to fully flatten the flexible screen at the folded position. The screen causes a certain degree of damage, which further affects the display quality of the foldable display, making...

Problems solved by technology

[0008] However, in these folding mechanisms, there is a certain gap between the outer surface and the inner surface during the opening and closing process; or the distance between the outer surface and the inner surface changes, and the inner and outer synchronization cannot be maintained.
