Abstract:
1. A handheld electronic device, comprising: a first body; a second body; a sliding module, coupled to the second body, wherein the second body is configured to slide between a first position and a second position via the sliding module; and at least one rotating module, coupled between the first body and the sliding module, the second body being configured to rotate relative to the first body via the at least one rotating module along an axis, wherein the second body is configured to receive a external force to rotate from the second position to a critical position, the at least one rotating module is configured to receive the force in order to store a potential energy, and the at least one rotating module is configured to release the potential energy to drive the second body to rotate from the critical position to a third position and form an included angle between the first body and the second body when the second body passes the critical position, and each rotating module comprises: a first axle rod, configured on the first body, wherein an extending direction of the first axle rod is parallel to the axis; a first positioning cam, disposed on the first axle rod, wherein the first positioning cam has a first positioning portion; a first rotating cam, disposed on the first axle rod, wherein the first rotating cam has a first mating surface facing the first positioning portion and a second positioning portion on the first mating surface, and the second positioning portion is configured to be coordinated with the first positioning portion; a first elastic member, coupled to the first positioning cam; and a first link rod, coupled between the first rotating cam and the sliding module, wherein when the second body rotates from the second position to the critical position, the first link rod drives the first rotating cam to rotate along the first axle rod, so that the second positioning portion and the first positioning portion are dislocated with each other to push the first positioning cam away from the first rotating cam, so that the first elastic member stores a first elastic potential energy, and when the second body passes the critical position, the first elastic member releases the first elastic potential energy to reposition the first positioning cam and drive the first positioning portion and the second positioning portion to a coordinated state, so that the first rotating cam continues rotating along the first axle rod to drive the second body to rotate from the critical position to the third position via the first link rod.
