Abstract
An exemplary hinge assembly includes a shaft, a cam, a cam follower, a first elastic member, a second elastic member, a first sleeve, a second sleeve. The cam and the cam follower are sleeved on the shaft. The first elastic member is sleeved on the shaft, and configured for producing an elastic force along the shaft. The first sleeve is sleeved on the shaft, and non-rotatably connected to the cam follower. The second sleeve is sleeved on the shaft, and non-rotatably connected to the cam. The second elastic member is sleeved on the shaft, and configured for producing an elastic force for driving the first sleeve to rotate relative to the second sleeve. The controlling member resists one of the cam and cam follower, and capable of driving the cam away from the cam follower.
