Document Type and Number:
WIPO Patent Application WO/2011/062307
Kind Code:
A1
Abstract:
The present invention relates to a generator apparatus for a vehicle, which uses the pressure exerted on the wheels of a vehicle while the vehicle travels to generate electricity to provide a source of driving power for a vehicle that is driven by electricity, such as an electric vehicle or a hybrid vehicle. A generator apparatus for a vehicle according to the present invention is installed on a rotating wheel of a vehicle and comprises: a generator module including a plurality of piezoelectric devices that generate electricity by means of pressure transferred from the ground through the wheel when the wheel rotates; a condenser for storing electricity generated by the generator module; and a connecting unit electrically connecting the generator module to the condenser. The generator module may include a supporting member installed on the wheel flange and covered by a tire, and the piezoelectric devices installed on the supporting member. The connecting unit may include: a rotating disk installed on an axle supporting the wheel, and having contacting terminals extending in a circumferential direction on one side of the rotating disk; a power connection member, one side of which is electrically connected to the generator module and the other side of which is connected to the rotating disk; and a contact connector supported on the axle or on the frame of the vehicle, and having a brush contacting the two contacting terminals.
