Bicycle power-generating hub based on piezoelectric material

Abstract

The invention relates to the technical field of bicycle power generation, in particular to a bicycle power-generating hub based on a piezoelectric material. The bicycle power-generating hub is characterized by comprising a bicycle hub structure, a piezoelectric material group piece module, an energy recovery and conversion circuit and an electric energy transmission slide ring. The bicycle weightis transmitted to wheels through the hub, acts on the road surface and forms balance with a counter-acting force. When the bicycle is ridden, the wheels rotate. The piezoelectric material group piecemodule is circularly stressed and then releases the stress, a piezoelectric material group piece produces voltage charge which is constantly transmitted to the energy recovery and conversion circuit and converted into electric energy which can be continuously used or stored, and the electric energy is transmitted to an electronic device or an electric energy storage unit for the bicycle through the electric energy transmission slide ring. Mechanical energy, heat energy and the like making the hub stressed and deform in the bicycle riding process are collected and converted into electric energy, the electric energy is provided for the bicycle and can be used by the electronic device or stored by a battery unit, and the riding kinetic energy consumption of the bicycle is not increased.

Description

technical field [0001] The invention relates to the technical field of bicycle power generation, in particular to a bicycle power generation hub based on piezoelectric materials. Background technique [0002] With the development of society, the progress of industry, and the increase of people's wealth and income, cars have entered ordinary people's homes. Cars bring convenience and comfort to human beings, but also bring congestion and pollution. Therefore, in recent years, under the policy of promoting low-carbon travel, bicycles have ushered in a new life. From new electric bicycles, assist bicycles, ordinary bicycles to shared bicycles. It provides convenience for our life and contributes to environmental protection. [0003] On electric bicycles, electric mopeds, shared bicycles and other bicycles that require electric energy, they are faced with the dilemma of battery life. Especially for shared bicycles, in the case of a huge number of possessions, the power suppl...

Problems solved by technology

Especially for shared bicycles, in the case of a huge number of possessions, the power supply and maintenance work of electronic locks, positioning devices and other electronic equipment is very difficult

[0004] At present, the existing bicycle power generation device uses the principle of electromagnetic power generation to consume riding energy

Or use solar power to generate electricity, which is not efficient and is seriously affected by the weather
