Self-generating schoolbag based on human body vibration energy collection

Abstract

The invention relates to a self-generating schoolbag based on human body vibration energy collection. The self-generating schoolbag based on human body vibration energy collection comprises a backpack, a fixed back frame, a movable back frame, two springs, a gear-rack group, a speed reducer generator group, a rectifier, a group of storage batteries, and a charging and protection circuit. The self-generating schoolbag based on human body vibration energy collection is characterized in that (1) the fixed back frame, the movable back frame, the springs and the backpack form a vibration energy collection unit, so that vibration energy is produced, amplified and collected; (2) the gear-rack group and the speed reducer generator group form a mechanical energy-electric energy conversion unit; (3)the rectifier and the storage batteries form an electric energy rectifying and storing unit, so that the produced electric energy is filtered, collected and stored; and (4) the charging and protection circuit forms a functional peripheral and interface unit, so that a user can conveniently and quickly use the stored electric energy. The self-generating schoolbag based on human body vibration energy collection provided by the invention is light and compact in structure, high in comfort, low in cost, and high in generating capacity, and is a sustainable green energy device.

Description

technical field [0001] The invention relates to a self-generating schoolbag based on human body vibration energy collection, which is used for collecting vibration energy of human body activities and generating power for small electrical appliances such as mobile phones. 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, and 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 ...

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.
