Human body wearable energy collector

Abstract

The invention discloses a human body wearable energy collector, and relates to the technical field of power generation devices. The energy collector comprises a thigh rod, a shank rod, a gear transmission speed increasing mechanism, a pressing plate, a connecting assembly, a first connecting shaft, and two energy collecting mechanisms which are symmetrically arranged on two sides of the thigh rod; the lower end of the thigh rod is rotationally connected with the upper end of the shank rod through a first connecting shaft, the gear transmission speed increasing mechanism is arranged on the shank rod and located between the thigh rod and the shank rod; the gear transmission speed increasing mechanism comprises a power output shaft, and the energy collecting mechanism comprises a coil box, a magnet box, a coil array, a magnet array and a one-way transmission assembly. The power output shaft can drive the magnet box and the magnet array to rotate unidirectionally relative to the coil array and the coil box through the one-way transmission assembly. The human body wearable energy collector provided by the invention is small in size, can be worn on the inner side of a knee joint to collect kinetic energy during movement of a person, is high in output performance, and can be used for supplying power to wearable electronic equipment.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a human body-worn energy harvester. Background technique [0002] In recent years, with the rapid development of wearable electronic devices such as smart bracelets, locators, and health monitors, as well as their wide application in medical, military, and Internet of Things fields, low-power wearable devices have increasingly become a part of people's daily life. an integral part of. With the rapid development of such wearable electronic devices, it also puts forward higher requirements for portable energy, such as longer service life and less pollution to the environment. In this regard, conventional electrochemical batteries are not suitable for powering wearable devices for a long time due to their limited lifetime and severe environmental pollution. Therefore, researchers at home and abroad have begun to turn their attention to sustainable green energy, su...
