Title:
FLIP DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/136735
Kind Code:
A1
Abstract:
Provided is a flip device, comprising a base body (1) and a cover body (2), wherein the base body (1) is provided with a notch matching the cover body (2), the notch comprises a bottom portion, and the cover body (2) is movably connected to the bottom portion of the notch; and the cover body (2) comprises a cover plate (21) and a torsion spring (22), and the cover plate (21) comprises a bottom end. The pre-set angle of the torsion spring (22) is, when the cover body (2) cooperates with the base body (1), between an opening angle of the torsion spring (22) when the cover is opened to the maximum extent and the opening angle of the torsion spring (22) is closed. By means of setting the pre-set angle of the torsion spring (22), when the cover plate (21) is opened, the cover body (2) is driven by a restoring force generated by the deformation of the torsion spring (22) itself to rapidly rotate and open. When the cover plate (21) is driven by the torsion spring (22) to return to the pre-set angle of the torsion spring (22), the torsion spring (22) is driven by the inertia and the weight of the cover plate (21) to continue to deform, such that energy is absorbed by means of the deformation of the torsion spring (22), thereby reducing the speed of the cover plate (21) to avoid producing a large mass impact and noise after the cover plate (21) is flipped up into position.
