Title:
ROTATING SHAFT MECHANISM AND FOLDABLE TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/184654
Kind Code:
A1
Abstract:
A rotating shaft mechanism (10), comprising a main support (1) and at least one rotating assembly (2); each rotating assembly can rotate relative to the main support so as to switch between an unfolded state and a folded state; in a matching structure of the main support and any rotating assembly, the main support has a first center of rotation (O1) and a second center of rotation (O2); the rotating assemblies each comprises a rotating part (21), a middle frame (22) and a sliding part (23), and the middle frame has a third center of rotation (O3); the rotating part can be connected to the main support so as to rotate about the first center of rotation, and the other end of the rotating part can be connected to the middle frame so as to rotate about the third center of rotation; one end of the sliding part is hinged to the main support, and the sliding part can rotate relative to the main support about the second center of rotation; and the other end of the sliding part slidingly matches the middle frame so that the middle frame is away from or close to the second center of rotation along the extending direction of the sliding part. The rotating shaft mechanism can have a good supporting effect for a flexible display screen during the unfolding and folding of a foldable terminal device, and the risk of failure of the flexible display screen is low. The present invention also relates to a foldable terminal device (100) comprising the described rotating shaft mechanism.
