A pedal-type piezoelectric power generation device and method

Abstract

The invention belongs to the technical field of power generation, and particularly relates to a pedal type piezoelectric power generation apparatus and method. The apparatus is characterized by at least comprising a pedal, a cover plate, a circular arc-shaped framework and a circular arc-shaped cavity body, wherein a rectangular groove is formed in the pedal; two supporting blocks are fixed at the left and right ends of the rectangular groove of the pedal; the two supporting blocks are used for supporting the cover plate; the sum of the supporting blocks and the height of the cover plate is equal to the depth of the rectangular groove; the supporting blocks and the cover plate are fixedly connected through screws; the shape of the inner circular arc-shaped surface of the circular arc-shaped framework is the same as that of the bottom circular arc-shaped surface of the circular arc-shaped cavity body; the circular arc-shaped inner surface of the circular arc-shaped framework and the bottom circular arc-shaped surface of the circular arc-shaped cavity body are fitted; and the circular arc-shaped framework, the circular arc-shaped cavity body and the pedal are connected through bolts, nuts and springs. The pedal type piezoelectric power generation apparatus is simple in structure, low in use cost and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a foot-operated piezoelectric power generation device and method, which are suitable for low-power electronic equipment that captures energy from human body movement and supplements energy. technical background [0002] In recent years, electronic information technology has developed rapidly, and many portable electronic devices have appeared, such as mobile communication tools, personal digital assistants, and medical electronic devices. These devices have relatively small power requirements, typically in the milliwatt range. At present, most of these mobile electronic devices are powered by batteries, but the battery power is limited, and when the battery power is exhausted, these devices cannot continue to work. In addition, waste batteries have caused significant pollution to the environment, and many arable lands have been polluted by heavy metals and c...

The application number is 201410711978.9, and the patent publication number is CN 104333262 A. It is also a pedal-type piezoelectric power generation device, but the energy collection method is relatively simple. It only considers the pressure of the human body on the heel, ignoring the human body walking or Energy collection of vibration and swing during motion, so the energy collection efficiency is not high
