1. A hinge assembly, comprising:
- 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, wherein 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 creating attraction, and the attracting force is changeable when the rotatable leaf is rotated relative to the fixing leaf; and
a fixing member fixed at an end of pivot shaft to prevent the rotatable leaf and the fixing leaf from detaching from the pivot shaft.

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.

15. A hinge assembly, comprising:
-
a pivot shaft; a rotatable leaf comprising a mounting portion and a supporting portion extending substantially perpendicularly from a side thereof, the supporting portion defining a pivot hole such that the rotatable leaf is rotatably sleeved on the pivot shaft via the pivot hole; a fixing leaf comprising a mounting portion and a connecting plate extending substantially perpendicularly from a side thereof, the connecting plate defining a deformed hole such that the fixing leaf the pivot hole is non-rotatably sleeved on the pivot shaft; a pair of first magnets fixed to the supporting portion adjacent opposite sides of the pivot hole of the rotatable leaf; and a second magnet fixed to the fixing leaf, wherein a polarity of the second magnet faces an opposite polarity of one of the first magnets in a first position, the polarity of the second magnet faces an opposite polarity of the other one of the first magnets in a second position, and attraction between the first and second magnets is changeable when the rotatable leaf is rotated relative to the fixing leaf. - View Dependent Claims (16, 17, 18, 19, 20)
