For some drivers or children with poor balance force, it is hard to drive the balance car. This device is through increasing two supplementary wheel carriers to become the tricycle with the single wheel, a plane can be confirmed to three points, consequently, just so that the foot steps on the platform comparatively stably. Thus, the auxiliary wheel can provide enough support when the balance car is in forward tilting or backward tilting braking, so that people can more easily keep stable balance.

The device is provided with the cushion 23 with adjustable height, so that drivers with different heights can sit on the balance bike conveniently. And in order to match this sitting posture, the present device is provided with a foot pedal 13. And forward and brake control is achieved using the foot pedal 13.

The pedals 13 on the two sides of the device are respectively connected with two connecting shafts, wherein the front part is in a sliding connection mode, and the rear part is in a rotating connection mode. The arrangement is such that when the foot pedal 13 is depressed, the slider is driven to move against the spring.

When the device is placed statically, the distance measuring sensors arranged in the travelling groove 11 and the braking groove 12 are positioned on the same horizontal plane. The front end of the pedal 13 is slightly higher than the rear end, and forms an included angle of about 5 degrees with the horizontal plane.

When forward travel is desired, the foot depresses the foot pedal 13 and then brings the toe below the heel. The distance variations detected by the two distance measuring sensors 111 are different at this time, and the variation value detected in the travel groove 11 is larger than that detected in the brake groove 12. Therefore, the system considers that the driver needs to advance, and the wheels are driven to do corresponding actions.

When braking is required, the pedal 13 is stepped on to make the height of the heel lower than the toe, and the change value detected in the traveling groove 11 is smaller than that detected in the braking groove 12. Therefore, the system considers that the driver needs to stop the vehicle and drives the wheels to do corresponding action

The device is ergonomically based.

When people run, the toes of the feet are naturally used to land on the ground without any training. In the long past, there has been a subconscious burn-in of obvious marks. Therefore, the device is set, the tiptoe is lower than the heel, and the balance car moves forwards.

When a human body encounters an emergency, the human body naturally leans backwards and intends to escape, and the heel of the foot is stressed greatly. Therefore, the present device is set such that the spring constant of the spring in the brake groove 12 is larger than that of the spring in the travel groove 11. When the driver brakes, the driver needs to step on the heel for a large distance, and the received resistance feedback is more obvious.

In addition, in the event of a sudden emergency, a human instinctively stomps his foot in preparation for his escape. In this device = the bottom of the slider 3 in the braking groove 12 is therefore provided with the conducting strip 32 and the two stops 15 are provided at the bottom of the braking groove 12. Two blocks 15 are made of conductive material and connected with the emergency brake system. When a foot is stomped, the conductive pad 32 is forced against the stop 15, which completes the circuit between the two stops 15 and triggers the emergency brake system.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
