Abstract
A hinge assembly includes a pivot shaft, a first supporting member, a second supporting member, and a positioning member. The first supporting member is rotatably sleeved on the pivot shaft. A positioning protrusion is formed on the first supporting member. The second supporting member is non-rotatably sleeved on the pivot shaft. The positioning member has an elastic portion and is non-rotatably sleeved on the pivot shaft. A positioning groove receiving the positioning protrusion is defined in a periphery of the positioning member and adjacent to the elastic portion. An LCD device is further provided in the present disclose.
Claims7
A hinge assembly, comprising:
- a pivot shaft;
- a first supporting member rotatably sleeved on the pivot shaft, wherein a positioning protrusion formed on the first supporting member;
- a second supporting member non-rotatably sleeved on the pivot shaft;
- and
- a positioning member non-rotatably sleeved on the pivot shaft, wherein a positioning groove and a sliding groove are defined in a periphery of the positioning member;
- the positioning member further defines an elongated curved cavity between the positioning groove and the sliding groove, and adjacent to the periphery of the positioning member, thus forming an elastic portion between the positioning groove and the sliding groove;
- when the first supporting member is positioned relative to the second supporting member, the positioning protrusion is received in the positioning groove;
- when the first supporting member rotates relative to the second supporting member to make the positioning protrusion disengage from the positioning groove of the positioning member, the elastic portion of the positioning member deforms and displaces into the cavity.
