Hinge mechanism and portable electronic device using the same
A hinge mechanism comprises a follower, a cam and a first spring. The first spring is spiral, one end of the first spring is mounted to the follower, another end of the first spring is mounted to the cam. The cam rotates relative to the follower about a rotating axis, the first spring is compressed to accumulate elastic force, until the line connecting two ends of the first spring is parallel to the rotating axis where the first spring is mostly compressed to accumulate maximum of the elastic force and the hinge mechanism is in an intermediate state. Once the cam is rotated over the intermediate state, the first spring is expanded under previously accumulated elastic force, which drive the cam continuously rotated relative to the follower.
