A heel embedded energy harvester

Abstract

The invention discloses a heel-embedded energy collector, which comprises a bottom plate, a pedal, a coil and a magnet box housing. The bottom plate is fixedly connected, and the coil is embedded on the top surface of the bottom plate. N pole magnets, S pole magnets and cantilever beams are fixed in the magnet box shell. One end of the cantilever beam extending out of the magnet box shell is fixedly connected with the bottom plate. The body is located above the coil; a bump is fixed on one side of the magnet box shell, and the bump and the end of the cantilever beam extending out of the magnet box shell are located on the same side of the magnet box shell and the bump is far away from the cantilever beam. The bottom end of the pedal is fixed There is a pressing block directly above the protruding block, the bottom surface of the pressing block is an inclined plane, and one end of the bottom surface of the pressing block close to the magnet case shell is higher than the other end of the bottom surface of the pressing block. The heel-embedded energy harvester of the present invention has a simple structure and a small volume, and can meet the power consumption demand of wearable electronic devices.

Description

A heel-embedded energy harvester technical field [0001] The present invention relates to the technical field of wearable power generation devices, in particular to a heel-embedded energy collector. Background technique In recent years, wearable electronic devices have developed rapidly, and their applications in the fields of medical, military and Internet of Things have become more and more widely. However, most of these devices are powered by electrochemical cells, which have little self-charging capability, and electrochemical cells Disadvantages such as limited lifespan greatly limit the length of time these devices can be used. Therefore, there is an urgent need to provide a real-time Wearable device powered devices to extend the life of wearable electronic devices. The available energy in the current environment includes light energy, thermal energy, mechanical energy and chemical energy, etc. The conversion of energy into electrical energy for utilization ...
