Abstract:
A hinge assembly includes a cam (13), a follower (14), a first spring (12), a control member (17) and a second spring (16). The cam has a first cam surface (135) and a second cam surface (136). The follower has a third cam surface (141) engaging with the first cam surface. The first spring provides an elastic force causing the cam surface of the cam and the third cam surface of the follower to resist each other. The control member has a fourth cam surface engaging with the second cam surface of the cam. The second spring is positioned between the control member and the follower. The control member is movable to push the cam to rotate to realize the first cam surface of the cam to rotate relative to the third cam surface of the follower.
