Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-generating device having both a piezoelectric effect and an electromagnetic induction effect,

The present invention relates to a self-generating device having both a piezoelectric effect and an electromagnetic induction effect, and more particularly, it relates to a self-generating device having both a piezoelectric effect and an electromagnetic induction effect, To a self-generating device having both a piezoelectric effect and an electromagnetic induction effect.

Most of the goods or devices that can be seen in the living environment or in the industrial field are powered by electricity. Demand continues to increase as society becomes more sophisticated. Most of the electricity generated from fossil energy such as coal and oil is generated by nuclear power generation.

However, since the conventional electric production method requires large-scale investment and causes pollution of the environment, investment and development are being actively carried out in various alternative power generation facilities such as solar power generation, wind power generation, and tidal power generation.

Electricity generated from a power generation facility is supplied to domestic and industrial devices or products requiring a relatively large use of electric power through a power cable, and is used as an energy source. However, electric power such as street lamps, small household appliances, And most of the products requiring activity are equipped with a secondary battery such as a primary battery or a lithium ion battery and are used as a power source.

However, the battery must be recharged when the power is discharged due to the limited usage time, and can not be used during discharging because it can not be charged while in motion or outdoors. In order to solve these problems, various self-generating devices have recently been developed so that power sources necessary for an emergency can be used.

For example, Korean Patent Registration No. 10-0890917 discloses a vibrating micro power plant having a base, a plurality of piezoelectric elements protruding from the base, electrodes formed on both surfaces of the piezoelectric element, and a connecting diaphragm connecting the piezoelectric elements to each other Lt; / RTI >

Korean Patent Registration No. 10-0622830 discloses a piezoelectric element comprising a laminated portion formed by laminating a plate-shaped piezoelectric element, a case portion surrounding the laminated portion to protect the laminated portion, and an external force transmitting portion for transmitting a force to the piezoelectric element, A compact high-efficiency generator in which a plurality of plate-shaped piezoelectric elements are arranged in series and in parallel is disclosed.

However, the above-described power generation apparatus disclosed in Korean Patent Registration No. 10-0890917 is an apparatus for generating electricity using a piezoelectric element, and can be applied to an article or an apparatus which is relatively small in volume and is subject to spatial limitation. However, The amount of electricity generated is so small that it can not be used as an energy source or a rechargeable power source in consideration of power consumption of electronic devices and small devices requiring electricity.

In order to solve such a problem, as shown in Korean Patent No. 10-0622830, it is possible to increase electric power generation by arranging a plurality of plate-shaped piezoelectric elements in series and in parallel. However, There is a limit.

In addition, since the piezoelectric element is very expensive, the manufacturing cost is too high when a large number of piezoelectric elements are used to construct the self-power generating device, so that the practical application is impossible.

According to the present invention, it is possible to reduce the resource cost required for the production of the existing energy because the self-power generation device can be installed in the stairway or the road block, .

In addition, electromagnetic induction power generation and piezoelectric power generation are performed by a single pushing downward force to increase the energy conversion efficiency, and the energy conversion efficiency is further increased as the re-power generation is performed in the reverse direction through the restoration means such as a spring.

In addition, by converting the forward force into rotational motion, it greatly increases the electromagnetic induction current production through linear motion and strikes the piezoelectric element through the impact element of the permanent magnet portion, thereby increasing the amount of the piezoelectric element, .
