Abstract

A suspension hinge that connects a liquid crystal display (LCD) to a roof of a vehicle has a central bracket, a first shaft assembly, a second shaft assembly and a third shaft assembly. The central bracket has a connecting wing, a first wing and a second wing. The first and second wings are oppositely formed perpendicularly on the connecting wing. The first and second shaft assemblies are respectively mounted pivotally on the first and second wings to allow the LCD to be opened and closed in relative to the roof. The third shaft assembly is mounted pivotally on the connecting wing to allow the LCD to rotate in relative to the roof. Then the viewing angle of the LCD can be adjusted easily.
