Abstract

The invention provides a friction generator, relates to the technical field of generators, and solves a technical problem of relatively low power generation efficiency of a friction nano-generator inthe prior art. The friction generator comprises a seat body, a ratchet wheel assembly and a movable assembly, wherein the ratchet wheel assembly is rotationally connected with the seat body, the movable assembly is located in the seat body, the movable assembly is distributed in the circumferential direction of the ratchet wheel assembly and can make contact with the ratchet wheel assembly, and afriction power generation unit is arranged between the movable assembly and the seat body. When the ratchet wheel assembly rotates, the movable assembly can do linear reciprocating motion to achieve friction power generation of the friction power generation unit. The friction generator is advantaged in that external wind energy or water flow energy and the like drive fan blades to rotate, electricenergy output is generated, and environmental energy capture is achieved.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a friction / electromagnetic composite generator based on a ratchet gear-increasing motion mode conversion type. Background technique [0002] With the rapid growth of world energy consumption, and the reduction of the amount of non-renewable fossil fuels, renewable and sustainable energy technologies have become an increasingly important research field. In life, the abundant and ubiquitous environmental mechanical energy can greatly meet the energy demand, so harvesting mechanical energy from the surrounding environment has become one of the most effective alternatives to solve the energy crisis. [0003] Friction electrification and electrostatic induction are common physical phenomena in nature. By rubbing different objects against each other, one side is negatively charged and the other is positively charged. When the two objects are separated by an external force for a cert...
