Energy storage type active energy harvesting device

Abstract

The invention provides an energy storage type active energy harvesting device. The energy storage type active energy harvesting device comprises a cavity, an energy storage module, a transmission module and an energy conversion module. The energy storage module is fixed inside the cavity, one end of the energy storage module is connected with the input end, and the other end of the energy storagemodule is connected with one end of the transmission module. The other end of the transmission module is connected with one end of the energy conversion module, and the other end of the energy conversion module is an electric energy output end. When the input end inputs mechanical energy, the energy storage module stores the part of mechanical energy, the stored mechanical energy is then transmitted to the energy conversion module through the transmission module, and the energy conversion module converts the part of mechanical energy into electrical energy for output. The energy storage type active energy harvesting device can convert the short-time and high-power mechanical energy input into long-time, continuous and asynchronous output electric energy.

Description

technical field [0001] The present invention relates to energy harvesting devices, and more particularly to active energy harvesting devices. Background technique [0002] At present, some portable electronic products and electronic devices such as sensors rely on traditional batteries to provide energy. Due to the shortcomings of traditional batteries that need to be replaced, charged, and maintained, the application of electronic devices is subject to many restrictions. Therefore, the researchers proposed to obtain energy from the surrounding environment to generate electric energy, but solar energy, wind energy, thermal energy and other energy are greatly affected by some natural factors such as day and night, climate, temperature, etc., and the input is unstable, thus making these electronic devices useless. Subject to certain restrictions. In addition, the mechanical energy that can be collected from nature is very small, so the output power of passively collecting mec...
