20110120742 | HINGE ASSEMBLY AND ELECTRONIC DEVICE USING THE SAME - A hinge assembly includes a first bracket, a second bracket and a shaft assembly rotatably connecting with the first bracket and the second bracket. The shaft assembly includes a shaft and an elastic member sleeved on the shaft. The shaft extends through the first bracket and the second bracket. The first bracket has a connecting end with a protrusion, the second bracket has a connecting portion defining a curved latching slot and a passing slot communicating with the curved latching slot. The width of the curved latching slot decreases along the curved extending direction, and the width of the protrusion is substantially the same as the width of one end of the curved latching slot, and wider than the other end of the curved latching slot. | 05-26-2011 |
20110157780 | HINGE ASSEMBLY AND ELECTRONIC DEVICE USING THE SAME - A hinge assembly includes a first pivot shaft, a second pivot shaft, a third pivot shaft, a first bracket, a second bracket, a first meshing wheel, a second meshing wheel, a third meshing wheel, and a transmission belt member sleeved on both the first meshing wheel and the third meshing wheel. The first pivot shaft, the second pivot shaft, and the third pivot shaft are substantially parallel. The first and second brackets are non-rotatably sleeved on the first and second pivot shafts, respectively. The third meshing wheel is disposed between the first meshing wheel and the second meshing wheel, and meshes with the second meshing wheel and the transmission belt member. An electronic device using the hinge assembly is also provided. | 06-30-2011 |
20110254419 | HINGE ASSEMBLY AND ELECTRONIC DEVICE USING THE SAME - An embodiment of a hinge assembly includes a main body defining a shaft hole, a connecting shaft including an inserting end rotatably received in the shaft hole, and an expansion member forming a tapered portion and axially positioned in the shaft hole. An end surface of the inserting end toward the expansion member defines a tapered hole corresponding to the tapered portion, and the tapered portion is pressed into the tapered hole to expand the inserting end to resist the inner surface of the shaft hole, thus rotatably connecting the connecting shaft to the main body. | 10-20-2011 |
20110289726 | HINGE MECHANISM - A hinge mechanism includes a first rotation assembly, a second rotation assembly substantially parallel to the first rotation assembly, a first connection member, and a second connection member. The first and second rotation assemblies include a first and second pivoting shafts and a first and second brackets sleeved on the first and second pivoting shafts, respectively, and both the first and second brackets includes an engaging portion eccentrically formed on one end respectively thereof. The first connection member includes two pivotal portions. The pivotal portions are rotatably connected to the engaging portions of the first bracket and the second bracket, respectively. The second connection member is sleeved on the first pivoting shaft and the second pivoting shaft. | 12-01-2011 |
