Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] Such as figure 1 As shown, a piezoelectric power generation sitting posture detection seat includes a seat body 1, an energy collection mechanism 2, a post-processing circuit, a battery and a controller. There are two energy harvesting mechanisms 2 in total. The seat cushion and the backrest of the seat main body 1 are all wrapped with sponge pads. The two energy collection mechanisms 2 are respectively arranged inside the seat cushion and the backrest of the seat body 1 . A vibrator is installed inside the cushion of the seat main body 1 .

[0030] Such as figure 2 with 3 As shown, the energy harvesting mechanism 2 includes a base 4 and an oscillating power generating unit. The base 4 is fixed in the seat main body 1 by bolts, and is used for carrying other components. The outer surface of the base 4 is provided with m placement slots, m=24, and the 24 place...

Abstract

The invention discloses a sitting posture detection seat based on piezoelectric power generation and power generation and detection methods thereof. At present, power generation seats in the market generally use photovoltaic power generation or electromagnetic power generation methods, but the methods have certain limitations. The sitting posture detecting seat based on the piezoelectric power generation comprises a seat main body and an energy collecting mechanism. The energy collecting mechanism comprises a base and oscillating power generation units. The base is fixed in the seat main body.M placement grooves are formed in the outer side surface of the base, wherein m is less than or equal to 100. One oscillating power generation unit is arranged in each placement groove. Each oscillating power generation unit comprises a force receiving plate, a first spring, a vibrator mass block, a second spring and a piezoelectric assembly. Each piezoelectric assembly comprises a piezoelectricsheet, a top arch-shaped stretching plate, a bottom arch-shaped stretching plate and a flexible sheet. By means of a spring system, instantaneous acting force on the seat when a human body sits down or leans back is converted into elastic potential energy of the springs, so that the energy storage function is achieved and continuous power generation is realized.

Description

technical field [0001] The invention belongs to the technical field of energy recovery and utilization, and in particular relates to a piezoelectric power generation sitting posture detection seat and a power generation and detection method thereof. Background technique [0002] Nowadays, people's demand for energy is increasing, and many researches are focused on the field of energy harvesting. The main purpose of these studies is to recover and convert wasted energy into useful energy. The human body is a huge source of energy, and the energy generated by the human body movement is huge every day, so collecting the energy generated by the human body movement is of great significance. At present, furniture has become a necessity of life in our country. With the continuous improvement of people's material life, the pursuit of furniture is not only based on its practicability. The human body frequently sits on the seat or sofa every day, so it is of great significance to in...
