ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/070681
Kind Code:
A1
Abstract:
The present invention enables a steady supply of power generated through vibratory power generation to a battery. An electric vehicle (1) according to the present invention comprises: a battery (6); first and second drive shafts (10, 11); an electric motor (2) that rotates the first drive shaft (10) through power from the battery; a clutch (3) that switches between a state in which the first and second drive shafts are connected to each other and a state in which the first and second drive shafts are not connected to each other; driving wheels (5); a reduction gear (4) that transmits rotation of the second drive shaft (11) to the driving wheels at a prescribed reduction ratio; and a vibration power generator (8) that is arranged so as to contact an outer circumferential surface of the first drive shaft. A cross section of at least a part of a portion of the first drive shaft in contact with the vibration power generator, the cross section being in the direction orthogonal to the rotation axis of the first drive shaft, is configured by a shape in which the distance from the rotation axis to the outer circumferential surface in not uniform. The battery is charged by power generated by the vibration power generator.
