Abstract
An exemplary hinge assembly includes a frame, a first rotating module, and a second rotating module. The first rotating module includes a first pivotal shaft non-rotatably connected to the frame. The second rotating module includes a second pivotal shaft substantially perpendicular to the first pivotal shaft, a plurality of resilient washers, a supporting member, a rotating member engaging with the supporting member, and a limiting member. A first end of the second pivotal shaft is fixed on the frame. The resilient washers, the rotating member, the supporting member, and the limiting member are orderly sleeved on a second end, opposite to that of the first end, of the second pivotal shaft. A position of the limiting member relative to the second pivotal shaft is adjustable. The second pivotal shaft is capable of driving the rotating member to rotate.
