Abstract

The invention discloses a pivoting friction generator. The pivoting friction generator comprises a first friction generating unit (100) and a second friction generating unit (200) which are arranged in an opposite manner, the first friction generating unit (100) and the second friction generating unit (200) comprise rotatable friction bodies (110, 210) and electrode bodies (120, 220) which sleeve the outer sides of the friction bodies, the friction bodies (110, 210) in the first friction generating unit (100) and the second friction generating unit (200) are in contact friction; and the electrode bodies (120, 220) of the first friction generating unit (100) and the second friction generating unit (200) are output electrodes of the pivoting friction generator. The invention also discloses the friction generating units. In the pivoting friction generator and the friction generating units, through the charge induction effect of the contact friction surface of a rotary roller and the electrode plate on the inner wall of a bracing frame, one-step friction of the contact friction surface can generate a multi-time generating effect, the generating efficiency is improved, and the generating capacity is guaranteed.

Description

Technical field [0001] The invention relates to a power generation device, in particular to a rotary friction generator and a friction power generation 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 wide. Therefore, if triboelectricity can be applied to the field of power generation, it will inevitably bring more convenience to people's lives. [0003] However, at present, most of the energy in the work of friction generators made according to the principle of friction power generation is used to overcome frictional force and converted into internal energy, which becomes useless work, while only a small part of the energy is used to overcome elect...

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.
