Power generation backpack based on piezoelectric effect

Abstract

The invention relates to a power generation backpack, in particular to a power generation backpack based on the piezoelectric effect. The power generation backpack based on the piezoelectric effect comprises an energy conversion module installed in the backpack, a power conversion module connected with the energy conversion module and an energy storage module connected with the output end of the power conversion module; the energy conversion module is used for converting mechanical energy generated in the human motion process into vibration energy of weights in the backpack and then converting the vibration energy of the weights into power energy, the power conversion module is used for converting and regulating the power energy collected by the energy conversion module, and the energy storage module is used for storing the converted and regulated power energy; the output end of the power conversion module is also connected with electric equipment which is connected with the energy storage module in parallel. According to the power generation backpack based on the piezoelectric effect, the mechanical energy generated in the human motion process can be converted into the power energy, and the power supply problem when an electric network is far away outdoors is solved, so that people can do outdoor sports more conveniently; meanwhile, the walking step number of people in the outdoor sports can be also calculated, and the sport interestingness can be increased.

Description

technical field [0001] The invention relates to a power generation backpack, in particular to a power generation backpack based on piezoelectric effect. Background technique [0002] With the development of the times, people's living standards have been significantly improved, and leisure and entertainment methods have gradually become diverse. Outdoor activities such as hiking in the wild and mountaineering in the wild have become an important part of people's holiday life. However, people can no longer conveniently charge electrical appliances such as electronic products and emergency lights outdoors. This has become an important issue restricting people's outdoor activities. Therefore, we urgently need to find a more convenient power generation method. [0003] The human body contains huge energy that has not been exploited and utilized by human beings. It contains chemical energy, electrostatic energy, thermal energy and mechanical energy.
