A wheel self-powered broadband energy harvester

Abstract

The invention provides a wheel self-powered broadband energy harvester, which includes a rotating bracket assembly and a fixed bracket assembly; the rotating bracket assembly includes a rotating bracket half-ring, two rotating bracket half-rings are provided, and the two rotating bracket half-rings are clamped and fixed It is arranged on the rotating shaft of the wheel to form a circle; a plurality of inner magnets are arranged at the center of the two rotating bracket half-rings, and a plurality of outer magnets are arranged at the edge positions of the two rotating bracket half-rings. The fixed support assembly includes a piezoelectric beam fixed frame, which is fixedly connected with the vehicle frame; multiple piezoelectric beam assemblies are equidistantly arranged on the piezoelectric beam fixed frame. The invention provides a self-powered broadband energy harvester for wheels. Through innovative structural design, the volume of the collector can be effectively reduced, and the energy collection efficiency of the collector can be improved.

Description

technical field [0001] The invention belongs to the field of energy harvesters, and in particular relates to a wheel self-powered broadband energy harvester. Background technique [0002] With the emergence of various new radio components, how to power low-power radio products has become the focus of attention. For example, the interior of shared bicycles needs to supply power to warning lights, lighting, and positioning systems. The common power supply method is solar power. When riding at night or in a rainy environment for a long time, it also needs to be powered by other means. The commonly used chemical batteries need to be replaced regularly and will cause pollution to the environment. Therefore, how to convert the energy in the surrounding environment into electricity and provide low power consumption? New energy harvesters that consume power from wireless products have become a research hotspot. Under the existing technical conditions, the piezoelectric vibration en...

[0002] With the emergence of various new radio components, how to supply power for low-power radio products has become the focus of attention. For example, the interior of shared bicycles needs to supply power to warning lights, lighting and positioning systems. The commonly used power supply method is solar power, and when When riding at night or in a rainy environment for a long time, other methods of power supply are also required. The commonly used chemical batteries need to be replaced regularly and will pollute the environment. Therefore, how to convert the energy in the surrounding environment into electrical energy and provide low power New Energy Harvesters Powered by Wireless Products Become a Research Hotspot

Under the existing technical conditions, the piezoelectric vibration energy harvester uses the positive piezoelectric effect to convert the vibration energy in the environment into electrical energy, does not need an external power supply, and has no pollution to the environment, but it has a large volume and needs further improvement in energy harvesting efficiency. raised questions
