Abstract
A hinge assembly includes a first rotating module and a second rotating module. The first rotating module includes a frame and a pivot mechanism positioned on the frame. The second rotating module includes a supporting body, a shaft, a rotating washer, a stationary washer, a resilient ring, and a nut. A first end of the shaft is fixed on the frame, and the supporting body, the rotating washer, the stationary washer, the resilient ring, and the nut are orderly sleeved on a second end, opposite to that of the first end, of the shaft. The nut fixes the supporting body, the rotating washer, the stationary washer, and the resilient rings to the shaft. The rotating washer and the stationary washer forms at least one protrusion and at least depression for receiving the at least one protrusion respectively. The pivotal shaft is configured to drive the stationary washer to rotate.
