Abstract
A hinge mechanism includes a pivot shaft, a resilient member coiling around the pivot shaft, a first cam, a second cam, and a rolling assembly. The pivot shaft defines a through hole in a radial direction thereof. The first cam and the second cam are sleeved on the pivot shaft, the first cam defines two pairs of recesses at one end surface thereof, and the second cam defines a groove at one end surface thereof facing the first cam. The rolling assembly positioned between the first cam and the second cam includes a pin and two rolling bearings sleeved on opposite ends of the pin.
Claims18
A hinge mechanism, comprising:
- a pivot shaft defining a through hole in a radial direction of the pivot shaft;
- a resilient member coiling around the pivot shaft;
- a first cam rotatably sleeved on the pivot shaft and defining at least one recess at one end of the first cam;
- a second cam sleeved on the pivot shaft and defining a groove at one end of the second cam facing the first cam;
- and
- a rolling assembly comprising a pin and at least one rolling bearing sleeved on the pin, wherein the pin penetrates the through hole of the pivot shaft and is received in the groove of the second cam, and the at least one rolling bearing is partially received in the groove of the second cam.
A hinge mechanism, comprising:
- a pivot shaft defining a through hole in a radial direction of the pivot shaft;
- a resilient member coiling around the pivot shaft;
- a first cam rotatably sleeved on the pivot shaft and defining at least one recess at one end of the first cam;
- a second cam non-rotatably sleeved on the pivot shaft and defining a groove at one end of the second cam facing the first cam;
- and
- a rolling assembly comprising a pin and at least one rolling bearing sleeved on the pin, wherein the pin penetrates the through hole of the pivot shaft and the at least one rolling bearing is held between the first cam and the second cam to engage with the at least one recess and the groove.
