Schoolbag based on human movement self-generating electricity

Abstract

The invention provides a schoolbag based on human movement self-generating electricity. According to the schoolbag, the human body kinetic energy is used, electricity generating with light burden at any time, carrying along with body and effectively is achieved through an electricity module matrix and a circuit and by using electricity generated by magnetic principle, the problem of uninterruptible power supply of outdoor long distance travelers is well solved, great convenience is provided for life of people, and communication and safety of long distance travelling are guaranteed. According to the schoolbag based on human movement self-generating electricity, the longitudinal displacement kinetic energy generated in various activities such as walking, running, climbing and down-going canaffect a magnetic block in an electricity generating unit to move up and down in a reciprocating mode, thus a magnetic field in a copper coil of the electricity generating unit is cut, current is generated, and then the current is input into a storage battery for storage after boosting through DC-DC.

Description

technical field [0001] The invention relates to a schoolbag for generating electricity, in particular to a schoolbag for generating electricity automatically based on human body movement. Background technique [0002] With the advent of the information age, people's lives are increasingly inseparable from various electronic devices, such as mobile phones, computers, GPS navigators, etc. The use of these facilities is inseparable from electric energy. At the moment when people like hiking and traveling, the outdoor charging of facilities has become a problem that needs to be solved urgently. [0003] At present, there are mainly the following types of portable self-generating equipment at home and abroad: 1) Products that use the kinetic energy of the human body to directly generate electricity. This is the earliest human-powered power generation equipment, such as hand-operated power generation, which relies purely on the movement of a single part of the human body. A seri...

AI Technical Summary

Problems solved by technology

There are mainly piezoelectric shoes and piezoelectric insoles on the market, which can power small accessories such as mobile phones through walking, but the height of the shoes needs to be increased, the sole material is uncomfortable and heavy, and the USB needs to be connected to the shoes when charging. The devices on it are also easily damaged; 3) Portable power generation products that use natural energy

Such products collect solar energy, wind energy and other natural energy through body wearable devices to generate electricity. Due to the influence of natural conditions, such devices cannot provide reliable sources of electric energy and can only be used as backup power sources. They are large in size and low in efficiency.

As far as the current products are concerned, although they can all be used to supply power to portable gadgets, they are not very convenient due to the limitations of weather, materials, structural weight, convenience, etc., and the power generation is not large and the efficiency is low.

[0004] In addition, most portable self-generating equipment at home and abroad, such as "a self-generating schoolbag based on human body vibration energy collection- 201810335682.X", etc., use a single power generation unit to generate power. The power generation sensitivity of the scheme is not high
