Title:
FOLDABLE SCREEN DEVICE AND HINGE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/051040
Kind Code:
A1
Abstract:
A foldable screen device. An elastic assembly (33) is provided on a support member (321); a first end of the elastic assembly (33) abuts against a main shaft mechanism (31) when a rotating mechanism (32) is rotated to a flattened state; a second end of the elastic assembly (33) is connected to the support member (321); and the elastic assembly (33) is in a compressed state when the rotating mechanism (32) is rotated to the flattened state, such that the elastic assembly (33) generates an elastic force, and when a user releases or reduces a force on a structure member (20) on one side of the support member (321) in a flattening direction, the second end of the elastic assembly (33) can drive the support member (321) to move away from the main shaft mechanism (31), and a flexible screen (10) is driven by the support member (321) and the structure member (20) to be flattened away from the main shaft mechanism (31), so as to avoid the situation that when a hinge assembly (30) is in the flattened state, the flexible screen (10) is arched at the connection position of the rotating mechanism (32) and the main shaft mechanism (31), ensure the flatness of the flexible screen (10) of the foldable screen device in the flattened state, improve the display performance of the foldable screen device, and also improve the service life of the flexible screen (10). In addition, a hinge assembly is further involved.
