Multifunctional friction power generating tire, sensor based on the same, and power supply equipment

Abstract

The invention discloses a multifunctional friction power generating tire, a sensor based on the same, and power supply equipment, and belongs to a friction power generator technology field. The power generating tire comprises a tire body and a conductive layer element. The tire body is integrated with the conductive layer into one body in a combined manner, or the conductive layer is attached to the surface of the tire, and an electrode is led out, and then a single-electrode or double-electrode integrated friction power generating tire is formed. The surface of the tire body is used as a first friction layer, and a surface of an insulation material and a surface of a non-insulation material in tire working environment are used as a second friction layer, according to an electrification by friction and electrostatic induction principle, the two friction layers are contacted with each other, and are separated from each other, and a potential difference between the two friction layers or between a friction layer and other area is generated by the rolling, the slipping, and the impacting of the tire, and the conductive layer element is used to output electric signals to an external circuit, and can be used as an independent sensor. A structure is simple, less materials are consumed, costs are low, preparation is easy, and the electric signals can be output, and the application range and the service lifetime of the tire are not limited.

Description

technical field [0001] The invention belongs to the technical field of friction generators, and in particular relates to a multifunctional friction generator tire, power supply equipment and an independent sensor. Background technique [0002] At present, mechanical energy is ubiquitous in life, and its magnitude also covers a wide range, but it is widely ignored by people. The present invention utilizes the basic idea of ​​converting mechanical energy into electric energy based on the principle of friction electrification and electrostatic induction, and provides a multifunctional friction power generation tire. The friction power generation tire is installed on the vehicle and machinery, and the mechanical energy generated by the tire rolling, bumping, deformation and other processes is converted into electric energy to provide electrical signals for the external circuit, forming a green and environmentally friendly power generation method. It can also be used as a sensor...
