Description

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 described in Korean Registered Utility Model Registration No. 20-0189611 (name: board for driving, 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; And a battery mounted on a lower portion of the foot plate to supply electric power to the driving motor. The foot plate has a feature in which a user carries out self-power generation by using a pressure at the time of loading by mounting a piezoelectric element module on the foot plate.

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.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall configuration view of a motorized kickboard to which a piezoelectric device according to an embodiment of the present invention is applied; FIG.
2 is an overall configuration view of a motorized kickboard to which a piezoelectric device according to another embodiment of the present invention is applied;
3 is an overall configuration view of a motorized kickboard to which a piezoelectric device according to another embodiment of the present invention is applied;

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited by the scope of the present invention.

FIG. 1 shows an overall configuration of a motorized kickboard to which a piezoelectric device according to an embodiment of the present invention is applied. FIG. 2 shows an overall configuration of a motorized kickboard to which a piezoelectric device according to another embodiment of the present invention is applied And FIG. 3 shows an overall configuration of an electric kickboard to which a piezoelectric device according to another embodiment of the present invention is applied.

1, a motorized kickboard to which a piezoelectric element according to the present invention is applied includes a foot plate 10 for mounting front and rear wheels 11 and 12 on front and rear ends thereof, A steering motor 30 connected to the rear wheel 12 and fixed to the foot plate 10 and transmitting power to the rear wheel 12; And a battery 50 mounted on a lower portion of the foot plate 10 to supply power to the driving motor 40,

As shown in FIGS. 2 and 3, the pedestal 10 is equipped with a piezoelectric element module 20 at an upper portion thereof, and is self-powered by a user using pressure at the time of boarding.

In addition, it is preferable that the piezoelectric element module 20 stores power generated during traveling in the battery 50, continuously supplies power, and self-generates power.

The piezoelectric element module 20 includes a piezoelectric element 21 attached to an upper portion of the footplate 10 and a piezoelectric plate 22 covering the footplate 10 on which the piezoelectric element 21 is mounted, And a piezoelectric spring 23 interposed between the pedestal 22 and the foot plate 10 to apply an elastic force to the piezoelectric plate 22 so as to be able to generate electric power by external pressure The piezoelectric plate 22 is connected to one side of the foot plate 10 by a hinge structure and the piezoelectric spring 23 is interposed only on the opposite side.

Therefore, the electric kickboard to which the piezoelectric element according to the present invention is applied can provide a kickboard in which the electric power generated by the external pressure can be stored in the battery and the driving force of the wheel for the progress of the kickboard can be easily obtained. It is advantageous in that it is more practical and convenient than a hand-operated kickboard having a large electric kickboard or one foot and inconvenient to continue rolling. Also, since it is easy to handle and easy to operate, anyone can easily use the kickboard It is possible to enhance the public's preference and satisfaction with the use of the Internet.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
