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. The side ends are unparallel and at least one of the side ends is inclined relative to the axis direction of the damper body to make the width of the pushing portion between the side ends be changed gradually, 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 respectively fixed to the stationary housing. Each rotatable sheet protrudes inwardly to form a retaining portion. The side ends of the pushing portion alternately contact the retaining portions and contact the retaining portions one by one when the elastic force of the hinge assembly is released to drive the damper body rotating.

The damping cover is fixed in the damping shell and has a center hole defined, an inner wall of the center hole defines a plurality of loop-shaped groove perpendicular to the center hole and parallel each other. The damping body has a column portion received in the center hole, the column portion protrudes outward to form a plurality of rotating plates perpendicular to the column portion and parallel each other. The rotating plates engage the corresponding loop-shaped grooves. A bottom of the column portion connects a connecting portion located beneath the damping cover. The outer gasket is arranged around the connecting portion and against an inner side of the damping shell. Damping oil is filled between the outer gasket, the damping shell and the damping body.

Abstract: A hinge apparatus includes a hinge and a damper and defines an axis direction. The damper includes a fixing housing defining an accepting hole therethrough along the axis direction, a rotating nut accepted in the accepting hole and defining an axis hole therethrough, a damping body accepted in the accepting hole and passing through the axis hole, two gaskets located over and under the rotating nut respectively, and a pushing body capable of pushing the damping body to rotate. Two rotating grooves are opened in a sidewall of the axis hole and extending helically along axis direction. Two sliding blocks are arranged on an outer surface of the damping body and extending helically along the axis direction, the sliding block engaging with the rotating groove. Damping oil is filled between the gaskets, the fixing housing and the damping body.

Abstract: A hinge apparatus includes a hinge and a damper. The damper includes a damping shell, a damping body, an outer gasket and a pushing body, damping oil is filled in the damper. The damping shell has a cylinder-shaped shell body, a cover is formed in the top of the shell body, a sleeve is formed in the shell body, and an annual groove is defined between the shell body and the sleeve. The damping body has a bottom base, an annular sidewall, and a recess defined between the bottom base and the annular sidewall. The annular sidewall is received in the annual groove. The sleeve is received in the recess. Inner grooves are opened in the inside of the annular sidewall, outer grooves are opened in the outside of the annular sidewall. The outer gasket around the annular sidewall and below the outer grooves, the outer gasket is against the inside of the shell body. The pushing body is capable of pushing the damping body to rotate under the elastic force of the hinge.

Abstract: A damper apparatus 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 and rotatable sheets and stationary sheets are respectively 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 two side ends of the pushing portion alternately engage the retaining portions and at least two of the retaining portions are different in width so as to make the side end of the pushing portion asynchronously contact the retaining portions. Damper resin is filled between the adjacent stationary sheets and rotatable sheets.

Abstract: A hinge includes a housing. A sliding cam slideably received in the housing defines concave portions and an axial hole. A rotatable cam mating with the sliding cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines an accommodating hole. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fixed at an end of the housing. A shaft received in the housing runs through the axial hole and the spring. An end of the shaft is received in the accommodating hole, and the other end of the shaft passes through the end of the housing. A first stop has a bottom surface whose part extends downward to form a blocking portion, and the rest part of the bottom surface is defined as a revolving platform. A second stop engaging with the rotatable cam has a top surface protruding upward to form a pushing block rotatablely disposed on the revolving platform.

Abstract: A hinge includes a housing. A stopper plugging up one end of the housing defines a through-hole. A sliding cam slideably received in the housing defines concave portions on a top surface thereof and an axial hole. A rotatable cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines a receiving hole. A top surface of the base portion protrudes upward and defines a stepped portion. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fastened around the stopper.

An end of the shaft is fixed with the stopper, and an opposite end of the shaft is received in the receiving hole. A damper has a top wall extending downward to form an enclosure. A top surface of the top wall protrudes upward to form a preventing block.

Abstract: A hinge with a position function includes a shaft housing and a pivot. The shaft housing has a pivotal portion and a fixed portion extending from one end of the pivotal portion. An opening is defined at the other end of the pivotal portion. At least two recesses extending along an axis of the pivotal portion are defined in the inner surface of the pivotal portion. The pivot has a swiveling member at one end thereof and a peripheral portion at the other end thereof. The swiveling member with at least a couple of locating portions is rotatably inserted into the opening of the pivotal portion, the locating portion is jammed into the recesses for a first location, and can slide out of the recesses and then slide against the inner surface of the pivot for being jammed into the recesses again to achieve a second location by the locating portions shrinking inward.
