Intelligent sneaker adopting magnet and coil for vibration energy acquisition

Abstract

The invention discloses an intelligent sneaker adopting a magnet and a coil for vibration energy acquisition. The intelligent sneaker comprises an energy acquisition device, a reverting type vibration absorption driver, a liquid spring, an elastic line, and an intelligent sneaker body. A permanent magnet group having a high-energy high-density magnetic array and an induction coil are disposed in the energy acquisition device in a built-in way, and then the intelligent sneaker body is capable of acquiring the vibration energy during walking of a user. During the walking of the user, the reverting type vibration absorption driver is extruded externally, and the liquid therein is extruded into a pipeline, and then the liquid extruded in the pipeline is used to push the permanent magnet group to carry out reciprocating motion. Under an action of a magnetic field, the induction coil wound on an induction coil winding rack is used to generate alternating current, and a rectification circuit is used to convert the alternating current into direct current, which is used to directly supply a wireless sensor and other milliwatt level devices with power, or is stored in an energy storage circuit, and therefore an object of acquiring the energy according to human paces is realized. The intelligent sneaker is advantageous in that the structure is simple, and by fully using unilateral magnetic energy effect, the efficiency of the energy acquisition is effectively improved.

Description

technical field [0001] The patent of the present invention relates to a smart sports shoe, in particular to a smart sports shoe that uses magnets and coils to collect vibration energy. Background technique [0002] Simple and low-power sensor systems continue to lead the development of wearable systems. People hope to be able to detect the amount of daily exercise, as well as the speed and acceleration of people walking, etc. through the sports shoes they wear. However, the energy supply of the detection device is an urgent problem to be solved. With the advancement of technology, energy harvesting technology provides a way for its energy supply without external energy sources. At present, researchers have proposed a variety of energy-harvesting methods by studying human gait. For example, an energy-harvesting device designed to take advantage of the sway of a sneaker and the impact of the heel on the ground when a person walks. However, with the continuous development of...
