Description

Speed bump generator {A Speed Bump Generator}

The present invention relates to a speed bump generator, and more particularly, is installed on the upper surface of a road where vehicles pass, but is not limited to the width of the road and corresponds to roads of various widths, and the existing speed bump function is performed, As a device that generates power by pressurization of a vehicle, it relates to a speed bump generator that generates energy without additional energy consumption.

Although the quality of life of people is improved due to the development of technology today, many problems such as environmental pollution, climate change and energy depletion are occurring due to the use of a lot of fossil fuels and energy due to the development of various technologies.

In addition, international oil prices are rising due to many recent international issues.

Due to these problems, the need to reduce carbon emissions is considered very important worldwide. In 2015, many countries joined the Paris Climate Change Agreement to prevent abnormal climate and global warming, and Korea is also a member It was decided to reduce or reduce carbon emissions by 37% compared to 2017 by 2030.

Currently, various new and renewable energy, eco-friendly energy and non-polluting energy are being researched and developed for this purpose, and the amount of use is also rapidly increasing.

These renewable, eco-friendly, and non-polluting energies use large-scale power plants and equipment such as solar heat, wind power, and hydroelectric power to store a lot of energy. The method of storing energy as a method is also a trend that is constantly being researched and developed.

Among them, research and development are being conducted on a device that generates and stores energy by adding a power generation device to an acceleration bump that is located on a road where a vehicle travels and prevents acceleration of the vehicle.

Speed bumps are not only installed on road sections where vehicle acceleration is prevented, such as residential areas and child protection areas, but are also installed in many places with various functions such as reducing traffic volume, securing pedestrian space, improving road scenery, and suppressing on-street parking.

Weight and friction are imposed on the speed bump by the vehicle, and a power generation device is additionally provided to generate and store power by using this motion principle.

However, the conventional speed bump generating device has a problem in that the height of the device cannot be maintained by the pressurization of the vehicle and the durability of the device is lowered due to repeated collisions with the vehicle.

In addition, the time the vehicle stays on the speed bump is very short, so it is not easy to operate the electronic parts, and it is difficult to apply it to places where the vehicle does not move frequently.

Accordingly, there is a need for a device having excellent durability and high energy generation efficiency.
