A variable resistance hinge is mounted in a notebook computer having cover and a base and the hinge has a stationary leaf, a pivoting leaf and a pressing assembly. The stationary leaf is attached to the base and has a keyed shaft. The pivoting leaf is mounted pivotally on the shaft and is attached to the cover. The pressing assembly is mounted around the shaft, presses the pivoting leaf against the stationary leaf and has a pivoting ring and a stationary ring. The pivoting ring rotates around the shaft, is attached to the pivoting leaf and has at least one stepped detent. The stationary ring engages the shaft, abuts the pivoting ring and has at least one friction protrusion. Each friction protrusion corresponds a stepped detent and provides variable friction when opening the cover to enhance lifespan of the hinge and facilitate opening of the notebook.

Variable resistance hinge

The present invention relates to a cover latch for an electronic device and includes a body, a latch bar, an actuator and a driver. The driver is connected to the cover body, the actuator and the latch bar. Only one hand is required to unlatch the cover latch by rotating the actuator and the driver that moves the latch bar.

Cover latch

A hinge assembly is mounted in an electronic appliance such as a notebook and has a stationary leaf, a pintle and a pivoting leaf. The notebook has a base and a cover. The stationary leaf is mounted securely on the base and has a pivoting sleeve having an outer edge, a limiting tab and at least one braking detent. The limiting tab and braking detent adjacently protrude longitudinally from the outer edge of the pivoting sleeve. The pintle is mounted rotatably in the stationary leaf and has an outer end and a limiting rod. The limiting rod is mounted securely in the pintle and selectively limits rotation of the hinge in both directions to leave a small gap when the cover folds toward the base to facilitate opening. The pivoting leaf is mounted securely on the outer end of the pintle and connects to the cover securely.

Hinge assembly

An antenna mounting bracket has a stationary leaf, a housing, a sliding plug and a spring. The stationary leaf has a connecting rod formed coaxially on and protruding from the stationary leaf. The housing is connected pivotally on the stationary leaf and has a proximal end, a distal end, a cavity formed coaxially in the proximal end and has a connecting leaf formed coaxially on and protruding from the distal end and attaching to an antenna. The sliding plug is mounted slidably in the cavity and presses against the connecting rod. The spring is mounted in the cavity between the housing and the sliding plug to press the sliding plug against the connecting rod. The antenna mounting bracket connects an antenna to a notebook computer and allows the antenna to fold against the notebook computer when not being used. Consequently, the antenna is stable when folded or extended.

Antenna mounting bracket

An antenna is mounted on a notebook and has a bracket, a pivot and a spring. The bracket has a sleeve and an arm. The sleeve has a cavity and a rail slot. The radially slot is defined radially through the sleeve and communicates with the cavity. The arm is formed on and extends outward from the sleeve to hold an antenna. The pivot has a chamber. The spring is mounted between the bracket and the pivot and has two ends respectively mounted in the cavity and the chamber. With the antenna hinge, the antenna pointing is adjusted easily and conveniently.
