HINGE
First Claim
1. A hinge applicable to a foldable electronic device, comprising:
- a hinge assembly adapted for producing and releasing an elastic force by rotating; and
a damper assembly connected coaxially with the hinge assembly, the damper assembly including;
a stationary housing defining a cavity with an opened end and a wall opposite the opened end,a damper body rotatablely installed in the cavity of the stationary housing, the damper body having a head, a cylindrical guiding portion axially protruding from the head and a pushing portion radially protruding from a portion of an outer periphery of the guiding portion, the pushing portion having two side ends apart from each other, at least one of the two side ends having a step-shaped profile to make the width of the pushing portion between the two side ends nonuniform, anda plurality of rotatable sheets and a plurality of stationary sheets respectively received in the cavity of the stationary housing and alternately disposed on the guiding portion and the pushing portion, the stationary sheets being fixed to the stationary housing, each of the rotatable sheets protruding inwardly to form a retaining portion, the two side ends of the pushing portion alternately contacting the retaining portions and contacting the retaining portions at intervals when the elastic force of the hinge assembly being released to drive the damper body to rotate to open or close the foldable electronic device, damper resin being filled between the adjacent stationary sheets and rotatable sheets for restraining the pushing portion rotating.

Abstract
A hinge includes a hinge assembly and a damper assembly. The damper assembly includes a stationary housing defining a cavity. A damper body rotatablely installed in the cavity has a head protruding to form a cylindrical guiding portion and a pushing portion defining two side ends apart from each other. At least one of the side ends has a step-shaped profile to make the width of the pushing portion between the side ends nonuniform, and rotatable sheets and stationary sheets are received in the cavity and alternately disposed on the guiding portion and the pushing portion. The stationary sheets are fixed to the stationary housing. Each of the rotatable sheets protrudes inwardly to form a retaining portion. The side ends of the pushing portion alternately contact the retaining portions and contact the retaining portions at intervals when the elastic force of the hinge assembly is released to drive the damper body rotating. Damper resin is filled between the adjacent stationary sheets and rotatable sheets.
