Abstract

The invention provides a shoe with a curve L-shaped mass block piezoelectric power generation device used, and belongs to the technical field of vibration energy recovery power generation. According to the shoe, the curve L-shaped mass block piezoelectric power generation device is installed in the shoe, the structure of a curve L-shaped mass block homogenizes strain distribution on a cantilever beam to some extent, and the energy density of a piezoelectric energy recovery device is improved, so that the recovery efficiency of vibration energy is improved; meanwhile, a rectifying circuit and a capacitor or a battery are arranged in the mass block, therefore, the whole device is compact in structure, the reliability is improved, and stored electric energy can be used for charging electronic equipment through conversion.

Description

technical field [0001] The invention relates to a novel piezoelectric energy collection device, in particular to an optimized curved L-shaped mass block piezoelectric power generation device. Background technique [0002] With the improvement of performance and the increase of screen size of mobile devices such as mobile phones and tablet computers, the power consumption of mobile devices is increasing day by day. How to replenish power for these devices has become an urgent problem. At present, the main solution is to use a mobile power supply, which is limited by the capacity of the mobile power supply, and also consumes power from the grid, which is not conducive to energy conservation and environmental protection. In addition, some power generation shoes often use mechanical means to drive small generators to generate power, which has many problems such as low comfort, too large size, which is not conducive to the transplantation of power generation modules, and is not e...
