Abstract:
1. A long stroke tilting hinge module for a portable terminal, comprising: a main body which is formed with an upwardly and downwardly elongated hole-shaped moving hole; a cover which is slid and tilted on an upper surface of the main body; a main lever of which one end is hinged to the main body and the other end is rotatably hinged to the cover; a sub-lever of which one end is hinged to the main body so as to be rotatable and movable up and down and the other end is rotatably hinged to the cover; a moving shaft which is inserted into the moving hole so that one end of the sub-lever is hinged to the main body; a cam which is coupled to a longitudinal center portion of the moving shaft; a support member which is fixed to the main body and disposed at the lower side of the cam and of which an outer surface is contacted with the cam; and a spring which is contacted with the moving shaft and which downwardly presses the moving shaft toward the support member, wherein the cam comprises a first cam surface which is formed into a curved shape and a second cam surface which is extended from the first cam surface and formed into a curved shape having a smaller diameter than the first cam surface, and the first cam surface is contacted with the outer surface of the support member when the cover is disposed at the upper side of the main body, and when the cover is slid to the rear side of the main body, each one end of the main lever and the sub-lever and the cam are rotated in one direction, the second cam surface is contacted with the outer surface of the su ort member and the moving shaft is moved down along the moving hole together with one end of the sub-lever by elastic force of the spring, thus a jumping space of the cover is reduced.
