Problems solved by technology

However, the efficiency of the coil cutting the magnetic induction line of the traditional electromagnetic induction power generation device is not high, and a lot of energy is lost in the friction inside the device, so the power output is limited

Abstract

The invention provides a magnet array planar rotation type energy harvester, which mainly depends on interaction during rotation of two circular permanent magnets which are closely adhered to the side wall of an annular permanent magnet. External vibration makes one circular permanent magnet to produce certain acceleration, when the circular permanent magnet with certain acceleration approaches a magnetic field range of the other circular permanent magnet, the other circular permanent magnet produces acceleration under the action of repulsive forces of magnetic fields between the two circular permanent magnets, and the two circular permanent magnets move in a reciprocated manner continuously and change positions rapidly till the two circular permanent magnets restore a magnetic field balancing state under the action of friction and electromagnetic damping between the circular permanent magnets and the side wall of the annular permanent magnet, thereby completing a process of inducting external vibration. The magnet array planar rotation type energy harvester can convert external vibration energy into electric energy maximally, is high in energy harvesting and conversion efficiency, and has broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of energy materials and devices, in particular to a device structure design of a magnet array planar rotation energy harvester. Background technique [0002] Outdoor sports are generally away from the city and close to nature. Necessary equipment such as communication, lighting, orientation, and first aid all require power supply, and long-term outdoor sports are even more important for the continuous supply of power. This type of equipment mainly relies on batteries for power supply, and the battery power supply time is limited. Although carrying multiple batteries can prolong the use time, it is cumbersome and heavy to carry. All kinds of shaking, acceleration, jumping and other actions in outdoor sports have action components on a certain plane. If the energy generated by these actions can be converted into electrical energy and stored for later use, or replenished at any time, then, This kind of electr...
