Problems solved by technology

[0002] Triboelectric nanogenerators can use the coupling effect of triboelectric effect and electrostatic induction effect to convert tiny non-electrical energy into electrical energy, and are widely used in various industries. However, in the working process, triboelectric generators need the stator and rotor Close contact during work can easily cause severe wear of the friction layer film and shorten the service life of the generator

Abstract

A friction generator according to embodiments of the invention comprises a stator, an electrode layer, a rotating shaft, a rotor and a polymer film, the surface of the stator is covered with the electrode layer, the rotating shaft penetrates through the stator, the stator cannot rotate along with the rotating shaft, the rotating shaft is sleeved with the rotor, the rotor and the stator are oppositely arranged at intervals in the axial direction of the rotating shaft, the rotating shaft can drive the rotor to rotate so as to enable the rotor and the stator to relatively slide, the polymer film is connected with the surface, facing the stator, of the rotor, the polymer film is in an arch shape, the polymer film is in an arc shape, and the top of the polymer film is in contact with the electrode layer. The friction generator has the advantages of being safe, reliable, high in adaptability and long in service life.

Description

technical field [0001] The invention relates to the technical field of energy conversion, in particular to a friction generator. Background technique [0002] Triboelectric nanogenerators can use the coupling effect of triboelectric effect and electrostatic induction effect to convert tiny non-electrical energy into electrical energy, and are widely used in various industries. However, in the working process, triboelectric generators need the stator and rotor Close contact during work can easily cause severe wear of the friction layer film and shorten the service life of the generator. Contents of the invention [0003] The present invention is based on the inventor's discovery and recognition of the following facts and problems: [0004] In actual use, in order to ensure the working effect of the generator, the stator and rotor are in close contact together. Long-term friction work will cause great wear on the friction surface, affect the size and quality of the output p...
