摘要： A hinge is mounted between a cover and a base of an electronic device. A lid covers the hinge and is attached securely to the base. The hinge has an arced surface and a rotating shaft. When the cover is pivoted to a certain angle, the rotating shaft abuts the arced surface to lift up the cover so the cover is selectively distant away from the lid. Therefore, the shape of the electronic device does not need to be disfigured and the cover still does not bump against the lid.

摘要： A hinge is mounted between a cover and a base of an electronic device. A lid covers the hinge and is attached securely to the base. The hinge has two tilting brackets, two tilting shafts, two linking assemblies and two actuating washers. Each tilting bracket has a mounting wing with an elongated hole and a mounting hole and a connecting wing with an abutting surface. The tilting shafts are mounted movably through the elongated holes. Each linking assembly has an actuating seat mounted around the tilting shaft, a holding seat formed on the actuating seat and protruding into the mounting hole and a resilient element mounted in the mounting hole and pressing against the holding seat. The actuating washers are mounted securely around the tilting shafts and selectively abut the abutting surfaces of the connecting wings to lift up the cover.

摘要： A hinge is mounted between a cover and a base of an electronic device. A lid covers the hinge and is attached securely to the base. The hinge has a cam wing, a sleeve, a rotating shaft and a pin. The rotating shaft is mounted slidably in the sleeve. The pin is mounted slidably and transversely through the sleeve, is attached securely to the rotating shaft and slides along the outer edge of the cam wing. When the cover is pivoted to a certain angle, the pin slide at part of the cam wing having larger diameter to gradually lift up the cover so the cover is selectively distant away from the lid. Therefore, the shape of the electronic device does not need to be disfigured and the cover still does not bump against the lid.

摘要： A hinge is mounted between a cover and a base of an electronic device. A lid covers the hinge and is attached securely to the base. The hinge has two cam wings, two tilting shafts and two actuating disks. The tilting shafts are mounted movably through the cam wings. The actuating disks are mounted respectively around the tilting shafts. Each actuating disk has an actuating protrusion sliding along the outer edge of the cam wing. When the cover is pivoted to a certain angle, the actuating protrusions slide at part of the cam wing having larger diameter to gradually lift up the cover so the cover is selectively distant away from the lid. Therefore, the shape of the electronic device does not need to be disfigured and the cover still does not bump against the lid.

摘要： A hinge assembly has a pintle, a stationary leaf, a rotating leaf, a rotating pressing disk, a stationary pressing disk, a biasing assembly and a fastener. The rotating pressing disk is mounted rotatably around the pintle, is attached non-rotatably to the rotating leaf and has a track face, an inner track and an outer track. The stationary pressing disk is mounted securely around the pintle and has a protrusion face, an inner protrusion and an outer protrusion. The inner and outer protrusions respectively contact slidably with the inner and outer track on the rotating pressing disk. With the arrangement of the inner and outer tracks on the rotating pressing disk and the inner and outer protrusions on the stationary pressing disk, the resistance provided by the hinge assembly is variable.

摘要： A rotary hinge for an electronic device with a cover and a body is mounted between a bottom of the cover and a top of the body and has a receiving assembly, a connecting assembly and a retaining assembly. The receiving assembly is connected to the cover. The connecting assembly is connected to the body and is attached pivotally to the receiving assembly. The retaining assembly is connected respectively to the receiving and connecting assemblies to selectively hold the cover at closed and open positions. With only one pivot between the rotary hinge and the cover, part of the body is exposed to allow the input unit being used when the cover is pivoted to open. Regardless of opening or closing the cover, the rotary hinge is hidden to prevent from damaging and foreign matters.
