Description

Energy collecting device for shoes

Technical Field

The utility model belongs to the energy harvesting field, in particular to an energy harvesting device for shoes.

Background

Nowadays, with the development of science and technology and the continuous progress of society, the green technology is increasingly paid attention to by people. The green technology is a technical system capable of reducing pollution, reducing consumption and improving ecology. Energy harvesting techniques are becoming increasingly important as new simple, easy and efficient methods are sought and researched to conserve and reuse energy. The energy collection technology is a technology for converting peripheral micro energy (external energy such as light energy, vibration energy, wind energy, heat energy, water energy and the like) into electric energy. The energy sources converted by the energy harvesting technology are very rich, and it is necessary to convert the external energy which actually occurs and is not utilized for effective reuse. Meanwhile, the converted electric energy can be used for supplying power to other electronic equipment, and the electric energy power supply system is wide in application range and can meet the power supply requirements of various industries. In addition, the converted electric energy does not depend on a battery or a power socket, and can directly provide electric energy for corresponding electronic equipment, such as charging portable electronic equipment and the like; in addition, the method can be effectively applied to occasions where electric power cannot be transmitted and reached, such as underground mines, deserts, remote areas and the like.

With the development of energy collection technology, there is a need to combine energy collection technology into shoes to supply power to the electricity utilization structure on the shoes by energy collection technology during walking. For example, the Chinese patent 'power generation shoe' with publication number CN102475371A uses the displacement of human body when stepping to push the pressure transmission device, and converts the displacement into the rotation of the gear, and then drives the power generation device to work to generate electric energy; when the foot is lifted, the elastic element on the gear can reset the device so as to realize reciprocating motion power generation. However, in the working process, the gear and the transmission device are always in a friction state, the effective torque of the tooth grooves is large, the gear and other devices are easy to damage, and the comfort of the sports shoes is influenced. Secondly, when the human body walks, the vertical displacement of the foot is small, and the pedaling energy of the human body cannot be fully utilized due to the gear rotation brought by the transmission device. Chinese patent publication No. CN102334772A, "multifunctional magnetic shoes", proposes an electromagnetic generator for foot, which is formed by pressing a human body while walking to move a permanent magnet up and down, so that a magnetic pole of a soft magnet in a coil nearby is changed continuously to cut a magnetic induction line, thereby forming a magnetic generator. However, the device has a small vertical displacement of the foot, and the effect of changing the magnetic poles of the soft magnet is not obvious.
