Abstract
The utility model relates to a novel piezoelectric bicycle seat for supplying power for a bicycle taillight, which belongs to bicycle accessories and is mainly composed of a seat casing, a drum type piezoelectric ceramic metal composite element, a support spring, a fixed rod, a bumper, a rectification circuit and a light-emitting diode (LED) bicycle light. The upper surface and the lower surface of a piezoelectric ceramic metal composite structure are connected with the rectification circuit. When the bicycle seat moves vertically along movement of a user, and certain radial extrusion force is exerted on piezoelectric ceramics through a force exertion component of the seat casing, so that continuous high voltage and low current are generated at the two ends of the piezoelectric ceramics which are rectified through the rectification circuit to be connected with the LED bicycle taillight to form a return circuit. The novel piezoelectric bicycle seat has the advantages of being simple in structure, low in manufacture cost and environment-friendly, and consuming no disposable energy sources.
