Patent ID: 7887019

Claim:
A support mechanism, adapted to an upper body of an electronic device, said upper body being capable of being turned pivotally relative to a lower body of said electronic device, said support mechanism comprising: a base, fixable on the lower body; a plate, fixable on the upper body; a transmission shaft, passed through and installed on said base and used for coupling said base to said plate to allow said plate to be turned pivotally relatively to said base, the transmission shaft having a groove formed thereon; and a torsional force generating device wound around said transmission shaft and said groove, one end thereof being extended outward and fixed on said plate, the other end thereof being unfixed and movable around the transmission shaft, the torsional force generating device having a width, along an axis of the transmission shaft, that is larger than a width of the groove, so as to reserve stress when a portion of the torsional force generating device is bound up in the groove; wherein, after said plate is turned pivotally upward, the weight of the upper body allows an inner side of said torsional force generating device to bind up said transmission shaft to generate a torsional force so as to support the upper body of the electronic device.
