Description

Motorized running board

The present invention relates to an electric traveling board capable of moving a passenger by driving a wheel by the rotational force of a motor.

In general, the driving board is called a kick board, and the children enjoy playing while riding, and are composed of a board supported by the front and rear wheels and a steering wheel for adjusting the driving direction. Such a driving board is a mechanism that allows you to enjoy a sense of speed by driving one of the front and rear wheels while hitting the ground while the other foot is placed on the board while adjusting the steering wheel.

In order to maintain driving, the driving board must continuously move the user's foot, and when the driving board is used for a long time, the enjoyment of driving may be halved, thereby increasing fatigue.

Meanwhile, recently, a traveling board equipped with a power device such as a motor has been introduced. In particular, the motor is driven by using a motor that is rotated by receiving power from a battery, thereby enabling electric driving.

As an example of such a traveling board according to the prior art, Korean Patent Publication No. 10-1529135 (hereinafter referred to as a patent document) discloses a folding electric traveling board.

However, the patent document is not provided with a suspension device mounted on a conventional moving means, so that the shock is transmitted to the user as it passes through the bottom uneven surface, which is not satisfactory in terms of riding comfort.

In addition, it is not possible to adjust the ground height of the running board there is a problem in that the stability during high-speed driving falls.
