2. Descriptions of the Related Art
Automobiles are common vehicles of modern people in their daily lives. Furthermore, the electric vehicle as environment-friendly transportation characteristic of neither air pollution nor environment noise is the main topic of current and future automobile development among issues such as oil depletion, energy efficiency, carbon reduction, and green application. In this regard, how to transform a running vehicle's kinetic energy to electric power is a popular topic.
Among current technologies, Taiwan Patent No. M390361 discloses a power generation apparatus converting kinetic energy generated by compression of wheels to electric power. The power generation apparatus comprises movable press plates on roads or rails run over by wheels, holders beneath the movable press plates, and a plurality of magnetic elements with same but repulsive polarity between the movable press plates and holders. Each of the movable press plates which are situated above roads or rails slightly comprises a gear rack laterally and first, second and third wheel gears for transmission of kinetic energy beside the gear rack: the first wheel gear is coupled with the gear rack and the second wheel gear; the second wheel gear (the third wheel gear) is centrally provided with a drive shaft; the second wheel gear spins in a unidirectional way due to a one-way bearing installed between the second wheel gear and the drive shaft; the second wheel gear and the third wheel gear are interposed by a volute spring; the third wheel gear is coupled with an alternator's gear wheel; the movable press plates run over by wheels generate kinetic energy which is used in driving the gear rack, spinning the first wheel gear and the second wheel gear, and screwing the volute spring; the volute spring releases kinetic energy to drive the third wheel gear and further the alternator's gear wheel for power generation.
The power generation apparatus based on the movable press plates on roads or railways run over by car wheels for electricity generation theoretically is a bulky, difficultly realized and unideal design increasing risks.
The patent application Ser. No. 095107881 discloses a device for recovering renewable energy with alternator, aerodynamic, and electronic valve powers which comprises: a tire which has a groove, a rim, and a stator silicon steel sheet with copper wires and magnetic sheets at a lateral edge; a rotary core fixed on the rim; a rotor disc installed on the rotary core; a magnetic sheet installed on the rotor disc and corresponding to the magnetic sheet on the stator silicon steel sheet; a pinion installed on the rotary core and coupled with the rotor disc's gear wheel; an eccentric shaft installed on the rotor disc; an air compressor cylinder situated at the stator silicon steel sheet and comprising a spring, a piston, vanes linking the eccentric shaft, and a splitter plate internally; a rotor lever centrally fixed in the rotor disc; two push rods opposite to each other and joining the rotor lever's two ends; a charger and batteries connected to the copper wires. As such, the device for recovering renewable energy with alternator, aerodynamic, and electronic valve powers promotes a vehicle's power, generating electricity, and inflating tires for less consumption of fuels.
The above technology for power generation is based on a rotary tire which drives a rotor lever and a rotor disc to spin and develop relative rotation between a rotor disc and a stator silicon steel sheet. However, the complicated apparatus for power generation is difficultly practiced and deserves to be rectified.
Despite feasible techniques of converting dynamic energy to electric power (e.g., alternator) theoretically, how to catch kinetic energy generated by a running car and apply the techniques by referring to a vehicle model are still kept pending. Accordingly, the main topics confronted by the person skilled in the art are to use kinetic energy of a running vehicle and rectify a conventional generating device of vehicle.
