Abstract: A hinge assembly includes a rotatable shaft, a rotatable stand, a fixed stand, a cam and a cam follower. The rotatable stand and the cam follower are non-rotatably connected to the rotatable shaft. The fixed stand and the cam are rotatably connected to the rotatable shaft. The cam is fixed to the fixed stand and contacted with the cam follower. The cam forms a limiting step, the cam follower forms a limiting surface on a periphery to abut against the limiting step. One of the cam and cam follower forms a positioning protrusion, the other one of the cam and cam follower defines a positioning groove to engage with the positioning protrusion.
