Document Type and Number:
WIPO Patent Application WO/2023/274233
Kind Code:
A1
Abstract:
A rotation shaft mechanism, which relates to the technical field of electronic devices having foldable screens. The rotation shaft mechanism comprises a main body (14), a first leaf (12), a second leaf (13), a middle leaf (11), a first swing arm (151) and a second swing arm (152), wherein the first swing arm (151), the main body (14) and the first leaf (12) can constitute a slider-crank mechanism, and the second swing arm (152), the main body (14) and the second leaf (13) also constitute a slider-crank mechanism; in addition, the middle leaf (11) can move relative to the main body under the driving of at least one structure of the first leaf (12), the second leaf (13), the first swing arm (151) and the second swing arm (152), such that the length of the rotation shaft mechanism can change with the folding of a flexible screen, thereby improving the reliability of the flexible screen.
