Abstract

The invention discloses an automobile ventilated seat cover with energy recovery function, which comprises a seat cover body, a piezoelectric vibration energy conversion device, a fan, and an air duct. When the car is running or stationary, the seat is subjected to human gravity and the seat is excited by external excitation to generate vibration, and the vibration will cause deformation of the spring of the piezoelectric vibration energy conversion device installed on the seat cushion and backrest of the seat cover , the spring deforms and acts on the piezoelectric ceramic sheet, which in turn causes elastic deformation of the piezoelectric ceramic sheet. When the piezoelectric ceramic sheet deforms, a voltage is generated and stored in the energy storage device. When the fan switch is turned on, it is used for Powers the fan on the seat cover.

Description

technical field [0001] The invention relates to a seat cover, in particular to an automobile ventilated seat cover with energy recovery function. Background technique [0002] The NVH characteristic is an important characteristic of a car that cannot be ignored. Vibration exists on a moving car all the time. A car is a high-speed moving object, and it will be excited by different frequencies of the road surface during the movement, and the whole car will have different degrees of bumps. and vibration. Since the passenger sits on the seat, when the whole vehicle vibrates, the mass of the passenger and the external excitation will cause the seat to deform. Piezoelectric energy harvesting utilizes the characteristic that piezoelectric materials can convert between mechanical energy and electrical energy, so as to effectively harvest vibration energy. With the development of piezoelectric materials, piezoelectric energy harvesters have been paid more and more attention. Theref...
