Abstract: A foldable supporting mechanism includes at least one hinge secured to a device, a bracket rotatably fixed to the device by the at least one hinge, and an elastic assembly secured to the at least one hinge. The supporting mechanism provides an elastic force to retain the bracket at an angle with the device when the bracket is unfolded. When the bracket is folded, the elastic assembly restores to continue urging the bracket to be fully retracted against the device. The at least one buffering assembly impedes the free rotation of the bracket relative to the device when the bracket is being unfolded and when it is being folded. An electronic device having the supporting mechanism is also provided.
