ABSTRACT:
A flip phone having a hinge mechanism with an auto-lock function includes a main body, a flipper, a sleeve shaft, a torsion spring, a first bush and a second bush, a torsion spring, and a first chute and a second chute. The torsion spring having a first spring end and a second spring end is disposed between the first bush and the second bush. The first spring end connected to the first bush synchronously rotates with the first bush and the second spring end connected to the second bush synchronously rotates with the second bush. The first bush is rotatably coupled to the first chute, and the second bush is rotatably coupled to the torsion spring chamber so that the flipper is rotatable around the hinge mechanism longitudinal axis to be in an opened position or a closed position. When the rotating object remains in the closed position, the torsion spring stores energy for unfolding the rotating object.
