Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] refer to Figure 1 to Figure 7 , a deformable shoe energy harvesting device, through the periodic movement of the foot on the ground and off the ground in the process of walking, through the electromagnetic device, the slight mechanical energy of the human body is converted into electrical energy, which is installed in the sole of the shoe. Powering the wireless sensor nodes. The specific structure is described below:

[0037] The device has a square base 1, see figure 1 , figure 2 , image 3 , Figure 6 , made of non-magnetic plastic, non-magnetic, requires good toughness and wear resistance.

[0038] Further, two identical "I" shaped lower yokes 2 are installed on the inner bottom of the base, see figure 1 , figure 2 , image 3 , Figure 5 , the lower yoke is fixed on the lower bottom and the side wall of the base by bonding, and each of the lower ...

Abstract

A shape change type footwear energy harvesting device is disclosed. Two identical lower magnet yokes are mounted on a bottom part of an inner side of a pedestal, the lower magnet yokes are fixed on alower bottom and a side wall of the pedestal, each of the lower magnet yokes is provided with two cylindrical installation shafts, an enameled copper wire coil is mounted on each installation shaft ofeach lower magnet yoke, a pair of wire coils are used as lead-out ends for electric energy collection, two lead-out ends are connected with an energy collection circuit, two ends of permanent magnetsare provided with round holes, installation shafts of the lower magnet yokes are mounted in round holes of the two permanent magnets, the permanent magnets are positioned above the wire coils, a nonmagnetic shape change rubber mat is embedded into a groove jointly formed by two lower magnet yokes and the pedestal, an upper part of the shape change rubber mat is provided with a rectangular blind hole, a bottom part of the rectangular blind hole is provided with a protruding stripe, an upper magnet yoke is mounted in a rectangular blind hole in the upper part of the shape change rubber mat, andthe upper magnet yoke is in contact with the protruding stripe of the bottom part of the rectangular blind hole of the shape change rubber mat. The shape change type footwear energy harvesting deviceis high in energy conversion efficiency, compact and reliable in structure, and simple and convenient in installation.

Description

technical field [0001] The invention belongs to shoes, and relates to the field of electromagnetic energy harvesting devices in smart wear, in particular to a device that is placed in the sole of a shoe and collects energy through the extrusion of the sole by human walking. Background technique [0002] People are walking every day, and the human body uses its own biological energy to do its own exercise. The "walking volume" of healthy people is at least 4,000 steps per day. This activity volume is the basic amount of exercise for people. To promote health and prevent various chronic diseases, the standard should be raised to 7,000 steps. [0003] When a person walks, when the shoe hits the ground, the ground and the foot press against the sole; when the shoe leaves the ground, the squeeze disappears. Therefore, it has become a focus of research and invention to take certain measures to collect the mechanical energy of this periodic extrusion process and convert it into el...
