Abstract:
1. A hinge mechanism, for pivotally connecting a flip onto a housing, comprising: a bush having a sidewall, a protrusion, and a receiving space defined by the sidewall, the protrusion being protruded from the sidewall; a camshaft having a first end, a second end, and a shaped notch, the shaped notch having a first concave portion and a second concave portion, the protrusion slidably received within the shaped notch, the first end of the camshaft slidably coupled to the bush, and the second end of the camshaft restrictedly coupled to the housing, so that the camshaft is only slidable relative to the housing substantially along a pivoting axis of the hinge mechanism; and an elastic means disposed within the receiving space and pressed by the camshaft and the bush; wherein when the flip is pivoted on the housing, the bush simultaneously rotates around the pivoting axis of the hinge mechanism so that the protrusion slides within the shaped notch from the first concave portion to the second concave portion.
