Power generation strap link buckle

Abstract

The invention discloses a connecting button of a power generation brace. The connecting button comprises a connecting button border, a giant magnetostrictive material power generation structure and an induction coil, wherein the connecting button border is used for connecting the connecting button of the power generation brace to external equipment, and the induction coil is sleeved on the giant magnetostrictive material power generation structure in a winding way and is connected with an interface circuit. The giant magnetostrictive material power generation structure is formed in a way of sequentially connecting a first magnet, a giant magnetostrictive material rod, a second magnet and a corrugated plate-shaped spring structure to form a closed magnetic circuit. The giant magnetostrictive material rod is made from a giant magnetostrictive material. The corrugated plate-shaped spring structure is made from a soft magnetic material and is in a corrugated-plate shaped structure. According to the connecting button of the power generation brace, part of mechanical energy generated by walking of people can be converted into electrical energy according to the converse magnetostriction principle, so that electricity can be supplied for various electric appliances or stored in electrical storage devices. The connecting button of the power generation brace is suitable for various types of knapsacks, is convenient to use and is widely applied.

Description

technical field [0001] The invention relates to the technical fields of mechanics and electricity, in particular to a connecting buckle for a power generation strap. Background technique [0002] With the continuous development of society, human beings are facing serious problems such as energy shortage and global warming. Finding and utilizing clean energy is one of the major issues that all countries are focusing on solving. In recent years, some researchers have begun to try to use human energy as an energy source. Human body energy harvesting technology mainly includes human body mechanical energy harvesting technology, human body thermal energy harvesting technology and human biological energy harvesting technology. [0003] People will produce shock and vibration when they are in motion. Harvesting these mechanical energy can conveniently provide energy for the electronic equipment they carry with them. Research on human vibration energy harvesting is the most promin...

Problems solved by technology

For a portable generator with an electromagnetic structure, the speed at which the coil cuts the magnetic induction coil depends on the speed of human body movement, usually the cutting speed is slow, so the power generation efficiency is low, so most of the power generation is increased by increasing the volume and weight of the power generation device For a portable generator with a piezoelectric structure, the electromechanical coupling coefficient and the mechanical quality factor determine its power generation. It is usually difficult for piezoelectric materials to have a high electromechanical coupling coefficient and a high mechanical quality factor at the same time, so the energy The conversion efficiency is not high

[0005] In recent years, a giant magnetostrictive material has emerged, which can also convert electrical energy into mechanical energy or convert mechanical energy into electrical energy. It has large strain, high energy density, large electromechanical coupling coefficient, fast response speed and large output force. advantages, and has begun to be initially applied in sensors and ultrasonic transducers, etc., but it has been applied to the energy harvesting of the human body is still seldom carried out
