Abstract

The invention discloses a rope reciprocating driving type multilayer electret rotary generator, and belongs to the field of micro-energy systems. The rope reciprocating driving type multilayer electret rotary generator comprises: a shell, and a driving assembly, a first power generation set and a second power generation set which are arranged in the shell, wherein the driving assembly is arranged in the middle in the shell and comprises a volute spiral spring, a large gear disc, a rope and a driving shaft, the whole device is driven by pulling the rope through external force, the first power generation set and the second power generation set are arranged on the two sides of the driving assembly respectively, power transmission is achieved through gear meshing, the driven shaft of a power generation resistor drives an electret plate to rotate and generate relative displacement with a conductive electrode plate, and changing charges are generated on the conductive electrode plate according to the electrostatic induction principle so as to generate current. According to the invention, rapid collection of mechanical energy and efficient conversion from the mechanical energy to the electric energy are achieved, and through combination of a mechanical structure and an electret power generation technology, loss of return motion energy during conversion of the mechanical energy to the electric energy in reciprocating motion is avoided so as to achieve gapless collection of the mechanical energy.

Description

technical field [0001] The invention belongs to the field of micro-energy systems, and in particular relates to a rope reciprocating-driven multi-layer electret rotary generator, which can convert reciprocating mechanical energy into electrical energy and can charge electronic equipment. Background technique [0002] In recent years, with the rapid development of mobile electronic devices, all aspects of work, study, life, and entertainment have been closely integrated with electronic devices. In a way, today's society cannot live without electronic devices. However, the limited battery capacity of electronic devices greatly limits the applicable environment of mobile power sources. How to invent a portable, environmentally friendly and sustainable emergency charging method is still an urgent problem to be solved. Although there are many mobile charging power sources on the market, they still rely heavily on direct power sources because they still belong to indirect power s...

Problems solved by technology

However, the power generation principle it adopts is electromagnetic, and the overall volume is relatively large. In order to ensure a certain energy density, it cannot be miniaturized.

And because the range of its up and down motion depends on the height of the whole structure, it cannot achieve a large range of motion

At the same time, when it reciprocates at a faster frequency, part of the rotational kinetic energy will be consumed due to reverse operation, and the energy is not fully utilized.
