Abstract

The invention provides a bicycle pedal power generation and lighting device. The bicycle pedal power generation and lighting device comprises a power generation device and a lighting circuit, wherein the power generation device is assembled on a bicycle pedal and is used for converting part of kinetic energy generated when the pedal is treaded into electric energy based on the piezoelectric effect of piezoelectric ceramics, and the lighting circuit is used for directly using the electric energy for lighting or directly storing the electric energy. All components of the device are embedded into the pedal and a cross beam of a bicycle, and the appearance of the bicycle is not changed. The bicycle pedal power generation and lighting device saves energy, is environmentally friendly and can achieve power supply for a long period.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to a bicycle pedal power generation lighting device which utilizes lead-free piezoelectric ceramics as the core component of energy conversion and generates electric energy through the piezoelectric effect. Background technique [0002] At present, bicycles are rarely equipped with lighting sources, and people have poor vision and low safety factor when riding at night. A small number of bicycles are equipped with lights, and most of them are powered by plug-in rechargeable batteries or disposable alkaline batteries. Battery charging and installation operations are extremely cumbersome, and waste alkaline batteries or lead-acid rechargeable batteries are harmful to the environment. [0003] Piezoelectric ceramics can convert mechanical energy into electrical energy through the direct piezoelectric effect, and convert electrical energy into mechanical energy through the inverse piez...
