Abstract
A hinge assembly includes a first pivot unit including a shaft, a bracket, an engaging member, a locking member, and an elastic member. The shaft has a non-circular sleeve portion. The bracket is rotatably sleeved on the shaft. The engaging member has a sleeving hole with a shape substantially corresponding to a cross-section of the sleeve portion of the shaft. The locking member has a sleeving hole with a shape substantially corresponding to a cross-section of the sleeve portion of the shaft. The locking member is non-rotatably latched to the engaging member. The elastic member is sleeved on the shaft to resist the components on the shaft.
Claims18
A hinge assembly, comprising a first pivot unit, the first pivot unit comprising:
- a shaft comprising a non-circular sleeve portion;
- a bracket rotatably sleeved on the shaft;
- an engaging member comprising a sleeving hole with a shape substantially corresponding to a cross-section of the sleeve portion of the shaft;
- a locking member comprising a sleeving hole with a shape substantially corresponding to a cross-section of the sleeve portion of the shaft, and the locking member non-rotatably latched to the engaging member;
- and
- an elastic member sleeved on the shaft to resist the locking member, the engaging member, and the bracket on the shaft, wherein the locking member and the engaging member are laminated together and resist each other in a vertical direction, a first side wall of the sleeving hole of the locking member and a first side wall of the sleeving hole of the engaging member each resist opposite sides of the sleeve portion of the shaft, a second side wall of the sleeving hole of the locking member opposite to the first side wall thereof and a second side wall of the sleeving hole of the engaging member opposite to the first side wall thereof are each spaced from opposite sides of the sleeve portion of the shaft.
A hinge assembly, comprising a first pivot unit comprising:
- a shaft comprising a sleeve portion;
- a bracket rotatably sleeved on the shaft;
- an engaging member non-rotatably sleeved on the sleeve portion of the shaft, the engaging member forming at least one latching portion;
- and
- a locking member non-rotatably sleeved on the sleeve portion of the shaft, and the locking member defining at least one latching slot fixed to the at least one latching portion by interference fit, such that the locking member non-rotatably latched latches to the engaging member, wherein the first pivot unit further comprises a base fixed to the shaft, a limiting member non-rotatably sleeved on the shaft, a fastening member fixed on the shaft, and an elastic member sleeved on the shaft;
- the limiting member forms a limiting flange;
- the bracket forms a limiting protrusion engaging with the limiting flange to restrict a rotation angle between the bracket and the shaft;
- the fastening member is mounted at an end of the shaft to prevent the elastic member, the limitation member, the locking member, the engaging member and the bracket on the shaft from disengaging.
A hinge assembly, comprising a first pivot unit, the first pivot unit comprising:
- a shaft comprising a non-circular sleeve portion;
- a bracket rotatably sleeved on the shaft;
- an engaging member comprising a sleeving hole with a shape substantially corresponding to a cross-section of the sleeve portion of the shaft;
- a locking member comprising a sleeving hole with a shape substantially corresponding to a cross-section of the sleeve portion of the shaft, and the locking member non-rotatably latched to the engaging member;
- and
- an elastic member sleeved on the shaft to resist the locking member, the engaging member, and the bracket on the shaft, wherein the bracket comprises a base portion and a first pivot portion defining a pivot hole;
- the shaft passes through the base portion, the hinge assembly further comprises a second pivot unit comprising an engaging member, a locking member, and a first connecting member;
- the first connecting member passes through the engaging member, the locking member, and the pivot hole of the first pivot portion of the bracket;
- an axis of the first connecting member is substantially perpendicular to an axis of the shaft.
