Folding hinge assembly and mobile terminal

Abstract

The invention relates to the technical field of flexible screens, and discloses a folding hinge assembly and a mobile terminal. A left shell, a right shell, a flexible screen and a middle shell are included; two synchronous motion mechanisms are arranged on the middle shell; the left shell, the right shell and the synchronous motion mechanisms are hinged at two sides of the middle shell through across coupler, so that the left shell and the right shell can synchronously rotate along the middle shell; an inner shell is fixedly installed over the left shell and the right shell respectively; andthe flexible screen is arranged over the two shells. By utilization of the synchronous motion mechanisms, the left shell and the right shell can be synchronously opened, so that the mobile terminal in the invention is conveniently opened and closed; by utilization of a screen avoidance mechanism, a space can be made for the flexible screen when closing, so that damage of the screen is avoided; byutilization of a movable cam mechanism, the use experience of a user can be improved; by utilization of the cross coupler, the friction force in a rotation process can be reduced; and the jamming phenomenon can be avoided.

Description

technical field [0001] The invention relates to the technical field of flexible screens, in particular to a folding hinge assembly and a mobile terminal. Background technique [0002] Flexible screens can be mounted on flexible materials such as plastic or metal foil. Using plastic instead of glass will make the display more durable and lighter. The flexible OLED panel is concave from top to bottom, with a bending radius of up to 700mm. [0003] When the existing flexible screen is bent, due to the large capacity occupied by the internal circuit board and other electronic devices, when the flexible screen is completely closed, due to the difference in the bending center point of the screen, the screen will be different from the internal electronic products. Extrusion occurs, causing wrinkles at the bends of the flexible screen, which can easily damage the screen over time.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a folding hinge assembly and a mobile terminal, which has the advantages of allowing the bending space for the screen when bending the screen, and solves the problem of the difference in the bending center point of the screen. It causes the screen and internal electronic products to be squeezed, resulting in wrinkles at the bends of the flexible screen, which is easy to damage the screen after a long time
