Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] refer to Figure 1 to Figure 9 , a magnetic conduction shoe energy harvesting device, through the periodic movement of the foot on the ground and off the ground during 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. Power consumption of wireless sensor nodes. The specific structure is described below:

[0034] The device has a rectangular base 1, see figure 1 , figure 2 and image 3 , made of non-magnetic plastic, non-magnetic, requires good toughness and wear resistance. The base is provided with a permanent magnet yoke limit card 1-1, a coil yoke limit card 1-2, a swing yoke front limit card 1-3 and two swing yoke side limit cards 1-4. The above-mentioned limit cards, especially the last three limit cards have higher wear resistan...

Abstract

The invention relates to a magnetic conductance type shoe energy collection device. A base is provided with a permanent magnet magnetic yoke limiting clamp, a coil magnetic yoke limiting clamp and pendulum magnetic yoke limiting clamps; a permanent magnet magnetic yoke is located in the permanent magnet magnetic yoke limiting clamp; a permanent magnet is cylindrical; one end of the permanent magnet is arranged in the permanent magnet magnetic yoke, and the other end of the permanent magnet is connected with an upper magnetic yoke; a hole matched with the permanent magnet is formed in one end of the upper magnetic yoke; a mounting hole is formed in the other end of the upper magnetic yoke; an enameled copper coil is arranged below the mounting hole of the upper magnetic yoke; a coil lead-out end is connected with an energy collection circuit; a coil magnetic yoke is located in the coil magnetic yoke limiting clamp; the coil magnetic yoke is provided with a mounting shaft; the coil is wound on the mounting shaft; the mounting shaft is inserted into the mounting hole of the upper magnetic yoke; and a pendulum magnetic yoke is located between the pendulum magnetic yoke side limiting clamps. The magnetic conductance type shoe energy collection device of the invention has the advantages of high energy conversion efficiency, structural reliability, and simplicity and convenience 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...
