Embodiment 1

[0055] The main body 1 of the electronic scale body is fixedly connected with the piezoelectric generator 2 .

[0056] see Figure 12 .

Embodiment 2

[0058] The body 1 of the electronic scale body is externally connected to the piezoelectric generator 2 through wires.

[0059] refer to Figure 11 , is composed of a scale body 1 and an independent external piezoelectric generating device 2, the piezoelectric generating device adopts 1 to 50 stacked piezoelectric generating units or array piezoelectric generating units, the piezoelectric generating device connects the scale with the wire Body connection to realize power transmission and supply to the human body scale to work.

[0060] Its working principle is: before the human body scale works, relying on the body's own weight or adopting one or more times of stepping, pressing, shaking and other force application methods, the external force acts on the piezoelectric power generation device that is externally placed on the scale body and can work independently, so that the piezoelectric power generation device The device generates electricity. The basic structure of the pie...

Embodiment 3

[0061] Embodiment 3 adopts a piezoelectric power generation device in which a laminated circular piezoelectric vibrator is fixedly supported around the periphery of the present invention.

[0062] The body 1 of the electronic scale body is fixedly connected to the piezoelectric generator 2, and the piezoelectric generator 2 adopts 1 to 50 stacked piezoelectric generator units, and the laminated piezoelectric generator unit adopts a laminated circular piezoelectric vibrator that is fixed around the periphery. Branch arrangement 201 is packaged by 1-50 layers of piezoelectric vibrator 20101, force transmission body 20102, isolator 20103 and shell 20104 arranged in parallel to the direction perpendicular to the surface of the vibrator; Structural form: The piezoelectric vibrator is circular, and is made of piezoelectric ceramic film 201011 and metal substrate 201012 by bonding and compounding, including single-chip and double-chip structures.

[0063] refer to Figure 1a , Figu...

Abstract

The invention relate to an electronic human scale with a self-powered function, which belongs to novel electronic human scales with self-powered functions. A main body of an electronic scale body is fixedly connected with a piezoelectric power generating device, or the main body of the electronic scale body is externally connected with the piezoelectric power generating device via a conductive wire, and the piezoelectric power generating device is fixedly connected with the upper portion, the inner portion or the lower portion of the main body of the electronic scale body. The electronic human scale needs no assistance of external energy sources and can effectively realize conversion from mechanical energy to electric energy to supply a power source for the work of the human scale only bypressing or treading of a human body and through a self-powered device combined with the human scale. The use of the electronic human scale is unlimited by time and space, and the electronic human scale has long service life, green and environment-protection property and wide application prospect.

Description

technical field [0001] The invention relates to a novel electronic human body scale with self-power supply function, which uses human body to step on or apply pressure and realize the conversion from mechanical energy to electric energy through a self-power supply device, so as to provide power for the operation of the human body scale. Background technique [0002] With the development of electronic weighing technology and people's continuous concern for their own health, human body scales, especially small household human body scales, have begun to enter thousands of households, and human body scales have become one of the important tools for people to measure their own health. Its power supply mode of the existing electronic human body scale in the market mainly contains two kinds: the one, battery power supply; The 2nd, solar power supply. Battery power supply is the most common way, but the battery has a certain service life, and the temperature and humidity of the envi...
