Heat-generating and heat-preserving shoes

Abstract

The invention relates to a pair of heat-generating and heat-preserving shoes, a piezoelectric power generator is mounted on each sole, an upper heat-preserving layer is arranged in each upper, a heat-generating layer made of carbon fiber material is attached in each upper heat-preserving layer, and power cords are led out of two ends of each piezoelectric power generator and directly connected with two electrodes in carbon fiber in the heat-generating layer respectively. The piezoelectric effect of the piezoelectric power generators is utilized for converting pressure energy of vamps to the bottom parts of the shoes during alternate motion of double feet of a person in the vertical direction to electrical energy, thereby replacing the functions of a mechanical rotation structure and an ordinary electromagnetic power generator thereof, not only greatly reducing the thickness and the volume, but also eliminating the need of using a mechanical reset spring, and further thoroughly solving difficulty in walking and other adverse effects due to the presence of the reset spring. In addition, the carbon fiber which is similar to cloth material is used as an electro-thermal conversion material for replacing electric heating wires, thereby ensuring that any parts in the heat-preserving shoes which need heat can be electrically heated, and not affecting the comfort of the shoes.

Description

technical field [0001] The invention relates to heat-insulation shoes, in particular to heat-generating heat-insulation shoes by converting motion energy into electric energy and electric heating. Background technique [0002] For special workers in severe cold areas (such as the People's Liberation Army standing guard), a pair of thermal insulation shoes with ideal functions is very necessary. And present heat-insulating shoes major part mainly adopted the heat-insulating material with good performance to reach the purpose of heat-preservation by avoiding the method that the heat in shoes loses as little as possible as far as possible, and obtained certain success. In addition, with the development of science and technology, some people also convert the vertical movement of the body weight through the instep (mainly the heel) into rotation through the mechanical structure according to the characteristics of the wearer's continuous movement of the feet in the cold environmen...

AI Technical Summary

Problems solved by technology

The existence of the return spring makes walking more difficult, because the feet need to be lifted relatively higher to lift the shoelaces off the ground, etc., so that its application is greatly limited
