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.
