<p>Disclosed is an apparatus using natural force to control bicycle power generation replenishing electrical energy of a storage battery. The particulars involve providing a gravitational engaging and disengaging apparatus and a drive apparatus, wherein the gravitational engaging and disengaging apparatus uses gravitational force to automatically control whether electricity charges a storage battery according to the state of travel of a bicycle. A drive apparatus (2) uses motive power of a bicycle rear wheel (72) to generate electricity, and emitted electricity charges a storage battery (3). The benefit is that in the case of no power source, the bicycle can be used to charge the storage battery. Using a self-locking mechanism (12) in the gravitational engaging and disengaging apparatus to control charging of the storage battery lightens the manpower load. Thus, when a bicycle is going downhill, the drive apparatus automatically couples with the bicycle and charges the storage battery. When the bicycle is going uphill or travelling along a flat, the drive apparatus automatically separates from the bicycle to lighten the manpower load.</p> |
