ABSTRACT:
A hinge assembly includes a pivot shaft, a rotatable leaf rotatably sleeved on the pivot shaft, a fixing leaf non-rotatably sleeved on the pivot shaft, a first magnet fixed to the rotatable leaf, a second magnet fixed to the fixing leaf, and a fixing member. A polarity of the second magnet faces an opposite polarity of the first magnet in a predetermined position such that the first and second magnets experience attraction. The attraction is changeable when the rotatable leaf is rotated relative to the fixing leaf. The fixing member is fixed at an end of pivot shaft to prevent the rotatable leaf and the fixing leaf from detaching from the pivot shaft.
