Description

Speed bump using piezoelectric element {A speedbump using piezoelectricity}

The present invention relates to a speed bump using a piezoelectric element, and more particularly, to a speed bump using a piezoelectric element capable of generating electricity by using kinetic energy of an automobile and installing optical fibers to improve visibility and reliability of the speed bump. It is about.

In general, the speed bumps form jaws that protrude to a predetermined height from the surface of the road by using urethane or asphalt in places where there is a danger of speeding or a risk of an accident, a sharp curve road, or a road around a school. It is installed to prevent human accidents caused by the vehicle by slowing down the speeding vehicle by applying paint containing reflective material on the upper surface.

However, in order to make it easier for the driver to identify the speed bumps, the surface of the speed bumps is painted with reflective material. However, due to environmental changes, such as flooding, heat, and friction with automobile wheels, the life of the reflective material is increased. As it is not long, it is not easy to identify at night, so the driver stops suddenly without recognizing the speed bumps.

In order to solve the above problems, Korean Patent Publication No. 10-2009-0000306 discloses a speed bump using POF. The speed bump using POF is composed of a speed bump body and a plastic optical fiber cable inserted into the body at a predetermined depth.

However, the speed bump using POF has a problem that the power required for driving the light source must be continuously made from the outside in order to transmit the light to the optical fiber, thereby increasing the use of the driving power of the public equipment. On the other hand, even if there is a case to supply power using sunlight or solar heat as having to install a large number of solar cells, there is a very difficult to secure space, it is difficult to generate power at night or cloudy weather, there is a problem of low productivity.

The present invention is to solve the above problems, it is possible for the driver to easily recognize the presence of the speed bumps to decelerate the traveling speed in advance, it is self-developed without a separate external power supply required for the light emission of the lamp The purpose is to provide a speed bump that can be powered.

The speed bump according to the present invention for achieving the above object is installed to protrude from the ground to decelerate the speeding vehicle, and is pressed by the tire of the vehicle installed inside the body and passes through the main body It includes a power generation unit having a piezoelectric element for generating a, and a light emitting unit that is installed in the main body so that the driver can recognize the speed bump, and emits light to the outside using electricity generated from the power generation unit.
