Electric generator and electric bicycle using same

The invention provides an electric generator and an electric bicycle using same; wherein the electric generator comprises a shell fixed on a bicycle frame, an outer rotor arranged inside the shell, anThe invention provides an electric generator and an electric bicycle using same; wherein the electric generator comprises a shell fixed on a bicycle frame, an outer rotor arranged inside the shell, and an inner rotor arranged inside the outer rotor; the shell has two drive gears that are rotatablely connected with a crank transmission shaft of the bicycle inside, wherein the outer rotor drive geard an inner rotor arranged inside the outer rotor; the shell has two drive gears that are rotatablely connected with a crank transmission shaft of the bicycle inside, wherein the outer rotor drive gear drives the rotation of the outer rotor through an outer rotor actuating mechanism, and the inner rotor drive gear drives the rotation of the inner rotor in a relatively opposite direction of the outedrives the rotation of the outer rotor through an outer rotor actuating mechanism, and the inner rotor drive gear drives the rotation of the inner rotor in a relatively opposite direction of the outer rotor rotation direction through an inner rotor actuating mechanism, thus leading the outer rotor and the inner rotor to rotate in relatively opposite direction; and electricity generated by the eler rotor rotation direction through an inner rotor actuating mechanism, thus leading the outer rotor and the inner rotor to rotate in relatively opposite direction; and electricity generated by the electric generator is transmitted to an electric motor through a circuit, and the electric motor drives the bicycle to advance. Under the magnetic flux-invariable situation, the drive moment and the drivctric generator is transmitted to an electric motor through a circuit, and the electric motor drives the bicycle to advance. Under the magnetic flux-invariable situation, the drive moment and the drive speed of the electric generator are correspondingly lowered, thus leading riders to consume less physical strength and avoiding the usage of storage batteries.e speed of the electric generator are correspondingly lowered, thus leading riders to consume less physical strength and avoiding the usage of storage batteries.
