Abstract

The invention relates to the technical field of generators, and discloses a friction nano-generator. A support frame in the friction nano-generator is fixed on a base; the top end of a central shaft is in bearing connection with a first friction disc and the bottom is in threaded fit with the support frame; the first friction disc is movably installed on a cover body and can be exposed out of an opening at the top of the cover body. A first friction layer is formed on the surface, facing the base, of the first friction disc; a second friction disc and the central shaft are mounted on the central shaft in a circumferential limiting manner; a second friction layer is formed on the surface, facing the first friction disc, of the second friction disc; a third friction layer is formed on the surface, deviating from the first friction disc, of the second friction disc; a third friction disc is fixed to the support frame and provided with a through hole for the central shaft to pass; and a fourth friction layer is formed on the surface, facing the second friction disc, of the third friction disc. A reset assembly is arranged among the first friction disc, the second friction disc and thethird friction disc. The friction nano-generator is simple in input mode, large in effective power generation area and capable of effectively increasing a power generation amount.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a friction nanometer generator. Background technique [0002] With the rapid development of modern science and technology, smart factories and smart roads are becoming more and more popular, and these smart structures require a large number of micro sensors, and their power supply methods generally use external circuits and batteries, which will make the system The power supply line is complicated, which increases the cost and difficulty of system maintenance; while the battery power supply has problems such as large battery size, short service life, and frequent replacement, which makes it difficult to meet the continuous working requirements of the sensor; at the same time, the battery contains heavy metals, and waste batteries are not properly disposed of. It will cause serious environmental pollution. [0003] Triboelectricity is one of the most common phenomena in nature...
