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.

Dependent claims

A hinge comprising:

a seat;
a central bracket connected to the seat and having
a body;
a pivoting shaft formed on and protruding out from a bottom of the body and mounted rotatably through the seat;
and
two tilting assemblies attached respectively to and protruding transversely out from two sides of the body;
a limiting assembly mounted between the seat and the central bracket and comprising
a first actuating unit comprising a first stop and a second stop;
a pivoting limit mounted pivotally between the first and second stops and having a first side and a second side;
and
a second actuating unit selectively abutting the first and second sides of the pivoting limit, wherein 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 of the pivoting shaft;
wherein the first side of the pivoting limit is adjacent to and selectively abuts the first stop when the second actuating unit abuts the second side of the pivoting limit;
wherein the second side is adjacent to and selectively abuts the second stop when the second actuating unit abuts the first side of the pivoting limit;
wherein the hinge further comprises a washer assembly having a limiting washer mounted securely around the pivoting shaft and located between the seat and the central bracket;
wherein the stops of the first actuating unit are formed on a bottom surface of the limiting washer;
wherein the pivoting limit is an elongated bar and is mounted pivotally on the bottom surface of the limiting washer;
and
wherein the second actuating unit is triangular and is formed on a top surface of the seat.
