Abstract:
1. A motor assisted rotating wheel mechanism, comprising: a frame body; a rotating wheel rotationally connected to the frame body; two cranks, each of the two cranks having a force-receiving member; a rotating axle disposed in the frame body with two ends connected with the two cranks, the force-receiving members receiving forces and providing a rotating power that drives the rotating wheel to rotate via the rotating axle; an auxiliary motor having a casing and being disposed between the two cranks, the auxiliary motor providing an electromagnetic field that is parallel to an axle core of the rotating axle, wherein output power of the auxiliary motor combines with the rotating power provided by the rotating axle to synchronically drive the rotating wheel to rotate, and wherein the auxiliary motor is equipped with a rotor and a stator, and the rotor is located in a central region inside the auxiliary motor while the stator is located on an outer region inside the auxiliary motor, so as to form one or more active surfaces of magnetic flux, wherein the rotor has a permanent magnet and a rotor seat for carrying the permanent magnet; a bearing, the rotor seat being coupled to the casing of the auxiliary motor through the bearing; one of a profile shaft, a key connection and buckles; a first driving device; and a driving device seat, wherein the rotating axle provides the rotating power for driving the rotating wheel to rotate through the first driving device and the driving device seat, and the rotor seat is coupled to the driving device seat through the one of the profile shaft, the key connection and the buckles.
