A seat with power generation function based on piezoelectric ceramics

Abstract

The present invention is a seat with power generation function based on piezoelectric ceramics, belonging to the field of daily necessities and industrial products; it includes a seat body, a seat support, a roller, an electrical equipment installation box and a slider guide mechanism; The front end is hinged with the seat bracket; the two rollers are symmetrically arranged at the rear end of the bottom surface of the seat body; two chutes are symmetrically arranged above the seat bracket, and the positions of the two chutes are opposite to the positions of the two rollers; The slider and guide rod mechanisms are respectively installed in two chutes, including sliders, guide rods and return springs; the seat body is rotated downward under pressure, driving the rollers to convert vertical displacements into horizontal displacements, and The pressure is converted into electrical energy by using the piezoelectric ceramics installed on it; a power management device is installed in the electrical equipment installation box to rectify, filter and store the electricity generated by the piezoelectric ceramics. The seat can make full use of station and airport space, and generate electricity for emergency lighting equipment charging.

Description

technical field [0001] The invention belongs to the field of daily necessities and industrial products, and in particular relates to a seat with power generation function based on piezoelectric ceramics. Background technique [0002] With the development of society, each city has built large and small stations. Most of these station waiting rooms and airport waiting halls have a relatively large flow of people, and they will be equipped with seats. On the one hand, most of these seats are only for The function of people sitting takes up a lot of valuable space resources but has a single function; on the other hand, people will inevitably sit up and sit up when waiting for a bus or a plane, repeatedly putting pressure on the seat, and the change of the body's center of gravity will generate gravitational potential energy. When the passenger flow is large, this energy is considerable; in addition, when the car is driving on the road, there will inevitably be bumps, and the bod...

Problems solved by technology

The present invention adopts the arc surface to install the piezoelectric ceramic, and the structure is relatively simple, but because the arc surface needs to roll to apply pressure to the piezoelectric ceramic, it cannot be applied to some occasions that have certain requirements for stability, such as a driving car It is necessary for the seat to provide effective support for passengers to ensure safety. In addition, because the seat body is not fixed, it is difficult to promote it in a large area in public places
