The invention also discloses a friction power generation unit. The rotating friction generator and the friction power generating unit of the present invention, through the charge induction effect between the contact friction surface on the rotating roller and the electrode plate on the inner wall of the support frame, make one friction of the contact friction surface produce multiple power generation effects, and improve the power generation efficiency , to ensure the power generation.

Description

technical field [0001] The invention relates to a generating device, in particular to a rotating friction generator and a friction generating unit. Background technique [0002] As we all know, when objects rub against each other, one side will be negatively charged and the other side will be positively charged. This kind of electricity generated by friction between objects is called triboelectricity. Triboelectricity is one of the most common phenomena in nature, and the conditions for generating triboelectricity are very broad. Therefore, if triboelectricity can be applied to the field of power generation, it will definitely bring more convenience to people's lives. [0003] However, at present, most of the energy of the friction generator produced according to the principle of friction power generation is used to overcome the friction force and convert it into internal energy, which becomes useless work, and only a small part of the energy is used to overcome the electros...

Problems solved by technology

[0003] However, at present, most of the energy of the friction generator produced according to the principle of friction power generation is used to overcome the friction force and convert it into internal energy, which becomes useless work, and only a small part of the energy is used to overcome the electrostatic gravitational force and convert it into electrical energy. Therefore, In the prior art, there is a lack of a friction generator that improves the power generation efficiency by changing the contact friction mode of the friction generator, reducing the instantaneous contact friction area and friction resistance.
