ELECTRIC KICK BOARD APPLICATION PIEZOELECTRIC ELEMENT < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kickboard, and more particularly, to an electric kickboard in which a piezoelectric element is mounted on a kickboard to store electric power generated by external pressure in a battery to drive the kickboard.

[0002] Driving boards, which are generally referred to as "kickboard" or "scooter ", are generally composed of board frame members supported by front and rear wheels and handles and other members for adjusting the driving direction, . Such a traveling board is a mechanism that allows one to enjoy a sense of passion and sense of speed by driving a front and rear wheels while holding a pair of feet on the board frame member while adjusting the steering wheel and holding the other foot on the ground.

The configuration of the board for driving as described above is disclosed in Korean Registered Utility Model Registration No. 20-0189611 (name: running board, Application No. 20-2000-006155) and Registered Utility Model Registration No. 20-0192306 Registration No. 20-0196549 (name: Kickboard, application number: 20-2000-011367) registered in the domestic registered utility model registration book No. 20-0204403 (name: Kickboard capable of being folded, application number: 20-2000-015700), and therefore, a detailed description thereof will be omitted.

In recent years, a board for driving equipped with a power unit such as a motor or an engine has been introduced. Particularly, an electric driving board driven by a motor is started by a battery or a battery power source as in the case of starting a car. Battery) power is supplied to the motor so that electric running is possible.

In the case of the electric kickboard as described above, there is an advantage that the power can be automatically obtained, but the structure is complicated and the volume is large, so there is a problem in handling and the cost is high.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems of the prior art.

Specifically, an object of the present invention is to mount a piezoelectric element module on a kickboard and to mount electric power generated by an external pressure on the battery to drive the electric kickboard.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an electric kickboard having a piezoelectric element according to the present invention, comprising: a foot plate for supporting front and rear wheels; A steering wheel connected to a front wheel fixed to the footrest and axially rotated to be steerable; A driving motor connected to the rear wheel fixed to the footrest and transmitting power to the rear wheel; A battery mounted on a lower portion of the foot plate to supply electric power to the driving motor; A front lamp mounted on the center of the steering wheel to illuminate the front surface, A rear lamp mounted on an upper rear surface of the rear wheel of the footrest and emitting light when a current is applied to illuminate the rear surface; And a lamp switch connected to the front lamp and the rear lamp to turn on / off the operation of each lamp,

The rear wheel has a rear wheel groove formed at its center so as to pass through the rear wheel shaft. A piezoelectric element is attached to the inner surface of the rear wheel groove, and a piezoelectric element covering ring covering the piezoelectric element is coupled to the rear wheel shaft.

As described above, the present invention provides a kickboard in which electric power generated by an external pressure is stored in a battery so that the driving force of a wheel for the progress of a kickboard can be easily obtained. Thus, an electric kickboard or a foot It is advantageous in that it is more practical and convenient than a manual type kickboard having inconvenience to continue to use, and since it is easy to handle and easy to operate, it can be easily used by anyone. Therefore, public preference And satisfaction can be increased.
