Abstract

The invention discloses a DC friction electric generator, which comprises a stator, a rotor, a casing, a conductive part, a V-shaped bracket, and front and rear end covers; The rotor friction parts on the outer wall are in close contact. By rotating the rotor, the rotating friction between the stator friction parts and the rotor friction parts generates current. The invention keeps the two friction parts in constant contact and friction through uniform circular motion, generates induced charges, electrons flow through the external circuit, and use the conductive parts as a current commutator to realize constant DC output; the invention has simple structure and low cost. It can directly and continuously supply power to electronic components without additional rectification equipment, and has good social and economic benefits.

Description

technical field [0001] The invention relates to a power generation device, in particular to a direct current friction power generation device. Background technique [0002] Conventional generators in the world rely on electromagnetic induction to generate electricity, using a large amount of ferromagnetic materials and conductive materials such as copper, which are heavy and costly, and even small motors are not easy to carry. Energy harvesting and conversion devices using nanotechnology are likely to play a key role in fabricating and driving self-powered nanodevices and system devices in the future. In 2012, the research group of Professor Wang Zhonglin from the Georgia Institute of Technology in the United States used the triboelectric effect and electrostatic induction principle to convert mechanical energy into electrical energy for the first time. At present, the output power of triboelectric nanomotors is sufficient to drive commercial light-emitting diodes (LEDs), i...
