Embodiment Construction

[0031] according to figure 1 , Piezoelectric ceramics are used as power generating devices to provide electrical energy for the entire device. The circuit principle of power supply and consumption of the device is simplified as follows:

[0032] Under the action of external force, piezoelectric ceramics will generate stress F inside, resulting in deformation of piezoelectric ceramics. The piezoelectric deformation of this device can be regarded as the bending of a cantilever beam. Under the action of lateral external force, the bending is mostly in the direction of the X-axis When taking a small micro-element segment to do integration, the average stress F, the electric storage capacity of the piezoelectric itself and its own thickness F P , the surface area A is related to the inherent stress and the stable dielectric constant ε in the X direction, then:

[0033] (1)

[0034] (2)

[0035] in:

[0036] F—average internal stress of piezoelectricity, Ψ—volume of monol...

Abstract

The invention discloses a multi-functional exercise and fitness piezoelectric generating article. The external shape of the article is similar to a dragonfly, and comprises a piezoelectric ceramics power generation system, an electricity storage system, an illumination system, a blowing system and a housing. The piezoelectric ceramics power generation system comprises piezoelectric ceramics, a pressure block, a pressure rod, a spring, a baffle plate, and a piezoelectric lead, and is capable of supplying electric energy for the whole device. The electricity storage system comprises movable storage batteries and fixed storage batteries, and charging and discharging in sequence can be achieved by means of feedback adjusting. The illumination system comprises two LED night lamps. The blowing system comprises a telescopic fan. All devices are mutually connected through leads, forming closed loops, which are disposed in the housing structure. The blowing system and the illumination system are controlled by switches. The invention is advantageous in that vibration generated by exercises and fitness is well converted into charge brought by piezoelectric effect, and the charge is converted,stored and utilized; the multi-functional exercise and fitness piezoelectric generating article is portable and small with various functions, and the added value of exercises and fitness is greatly increased.

Description

technical field [0001] The invention relates to the field of daily life and energy electronics technology, especially refers to making piezoelectric power generation and utilization through exercise and fitness. Background technique [0002] People are paying more and more attention to physical health. Physical exercise has become the mainstream of life. Long-term single exercise will produce a sense of boredom and our exercise is only limited to physical health. For fitness alone, physical exercise is indeed It is understandable, but its limitations are inevitable, and fitness exercises have been recognized by most people, and the trend is increasing year by year, accounting for 67.5% of the total population. However, today's fitness methods do not have the resources to carry out Reasonable use. In this regard, whether physical exercise can be combined with the maximization of resource utilization and the convenience of life, and how to increase the added value of exercise...
