ABSTRACT:
A hinge mechanism includes a shaft (1), a cam follower (12), a cam (2), an antifriction member (3), a washer (4) and an elastic member (5). The cam follower is fixed relative to the shaft and has a cam follower surface. The cam has a cam surface (24) and a cam hole defined therein. The cam is rotatable relative to the cam follower. The shaft runs through the cam, the washer and the elastic member, in turn. The antifriction member has one end touching the cam and an opposite end touching the washer. The cam surface abuts against the cam follower surface due to the elastic force of the elastic member. As the friction coefficient between the antifriction member and washer is smaller than that between the cam and the washer, the hinge mechanism generates a smaller friction therebetween, so the waste of energy is very small.
