Abstract: The invention relates to an electrical hinge assembly and an electric device using the same. The electric device includes the electrical hinge assembly, a first slab and a second slab. The electrical hinge assembly includes a first holder and a second holder. The first holder comprises a shaft body. The shaft body includes a central shaft and a conductive layer. The conductive layer covers the central shaft. The second holder comprises a tube body. The tube body surrounds the shaft body capable of being rotated. The first slab is fastened with the first holder and comprises a first electrical component. The first electrical component is electrically connected to an end of the conductive layer. The second slab is fastened with the second holder and comprises a second electrical component. The second electrical component is electrically connected to another end of the conductive layer.

Abstract: A sliding hinge has two sliding assemblies mounted on a cover of an electronic device, two pivoting assemblies mounted on a base of the electronic device and two retractable connecting assemblies. An end of one retractable connecting assembly is connected to the end of the other retractable connecting assembly. Another end of each retractable connecting assembly is pivotally connected to a corresponding sliding assembly and a corresponding pivoting assembly. The two retractable connecting assemblies of the sliding hinge provide sufficient resilient force to push and hold the cover of the electronic device, especially a large-sized electronic device, at the closed or open position.

Abstract: A hinge is mounted between a cover and a base of an electronic device and has a first actuating unit, a pivoting limit and a second actuating unit. The first actuating unit has two tops. The pivoting limit is mounted pivotally between the stops. The second actuating unit selectively abuts a first side and a second side of the pivoting limit. When the second actuating unit abuts one of the sides of the pivoting limit to pivot the pivoting limit, one of the sides of the pivoting limit abuts one of the stops to limit the rotating angle. With the pivot of the pivoting limit, the rotating angle is increased. Therefore, the cover of the electronic device is fully rotatable by 180 degrees in either direction, and the hinge still provides limiting function to protect inner wires.

Abstract: A hinge assembly is used in a notebook computer and has a rotating bracket, cover panel, stationary bracket, limiting assembly and indicator ring. The notebook computer has a display and a base. The display is rotatably mounted pivotally upon the base. The rotating bracket is attached to the display and has a keyed shaft. The cover panel is mounted around the rotating bracket, is attached to a top surface of the base and has a gap. The stationary bracket is mounted rotatably around the keyed shaft and is mounted securely on the base. The limiting assembly is mounted on the stationary bracket and allows the keyed shaft to rotate 360°. The indicator ring is mounted on the limiting assembly and has two indicators. The indicators show up in the gap when the display is rotated to a rotational limitation to indicate direction of allowed rotation.

Abstract: A hinge has a main frame, a pivoting bracket and a limiting assembly The main frame is attached to a base of an electronic device. The pivoting bracket is attached to a cover of the electronic device and has a rotating rod being mounted through the main frame. The limiting assembly has a first actuator, a second actuator and a guiding pin. The first and second actuators are rotated relative to each other. The guiding pin is mounted between the first and second actuators and is moved relative to the actuators to allow the cover to be rotated clockwise and anticlockwise by 180 degrees, relative to the base. Therefore, a screen on the cover can be adjusted at wishes.

Abstract: A hinge assembly is used in a notebook computer and has a combination bracket, a keyed shaft, a stationary bracket, a limiting assembly and a pressing assembly. The notebook computer has a monitor panel and a base. The monitor panel is mounted horizontally pivotally upon the base. The combination bracket is attached to the monitor panel. The keyed shaft is attached securely to the combination bracket. The stationary bracket is mounted rotatably around the keyed shaft and is mounted securely on the base. The limiting assembly is mounted rotatably on the stationary bracket, is connected to the keyed shaft and allows the keyed shaft to rotate 360°. The pressing assembly is mounted around the keyed shaft below the stationary bracket to provide friction. Consequently, the hinge assembly allows the monitor to rotate 360° relative the base.

Abstract: A hinge for a notebook extension pad is mounted in an expansion pad of a notebook and has a pivoting assembly, a positioning disk, a limiting stationary leaf, a limiting disk, a pressing assembly and a locking assembly. The expansion pad has a mounting segment and a pad. The pivoting assembly is mounted securely on the pad and has a shaft. The positioning disk is mounted around the shaft. The limiting stationary leaf is adjacent to the positioning disk, is mounted rotatably around the shaft and connects with the mounting segment. The limiting disk limits movement of the pad relative to the mounting segment. The pressing assembly provides friction against movement to the hinge. The locking assembly is mounted around the shaft and selectively holds the pad at an angle allowing the pad to be used to display the notebook for presentations or achieving a comfortable typing angle.
