Patent ID: 8205301

Claim:
A hinge assembly, comprising: a first bracket defining one of a damping protrusion and a depression; a second bracket being rotatable relative to the first bracket; a damping member defining the other one of the damping protrusion and the depression, the damping protrusion engaging with the depression; and a torsion resilient member connected to the first bracket and the second bracket to urge the first bracket to rotate relative to the second bracket and the damping member; wherein the engagement of the damping protrusion and the depression prevents the first bracket from rotating relative to the damping member, and the first bracket together with the damping member are rotatable relative to the second bracket to any desired angle; wherein the hinge assembly further comprises a shaft, a limiting unit, an elastic unit, a first fastening member, and a second fastening member; the first bracket, the second bracket, the limiting unit, the torsion resilient member, and the elastic unit are sleeved on the shaft, with the first and second fastening members positioned at opposite ends of the shaft; the limiting unit comprises a steady member and a rotatable member rotatably engaged with the steady member, the steady member comprises a limiting protrusion and the rotatable member comprises a limiting flange engaging with the limiting protrusion to restrict a rotation angle between the rotatable member and the steady member; the shaft comprises a flange, a first shaft portion, a joining portion, and a second shaft portion, with the first shaft portion, the flange, the joining portion, the second shaft portion arranged in that order; the flange has a diameter larger than other portions of the shaft; the damping member and the rotatable member are non-rotatably sleeved on the shaft; the first bracket, the second bracket and the steady member are rotatably sleeved on the shaft.
