The number of wheels 2 is two, and the wheel 2 includes a first wheel 21 and a second wheel 22. The pedal mechanism 3 includes a pedal 30 which is located outside the wheel 2 and has two pedals 30, including a left pedal 31 and a right pedal 32. In this embodiment, the left pedal 31 and the right pedal 32 are in the form of a sheet, and the outer side has a non-slip flap. The connecting mechanism 4 is located between adjacent wheels 2, and the end of the connecting mechanism 4 is connected to the pedal mechanism 3, the length of the connecting mechanism being smaller than the spacing of the adjacent wheels. The control system is located between adjacent wheels 2, the control system comprises a plurality of controllers 5, the controller 5 acquires the sensing signals detected by the sensors, controls the corresponding hub motor to drive the corresponding wheel 2 rotation; the power source 6 is located in the adjacent wheel between.

The pedal mechanism 3 further includes a pedal cover 33. The pedal cover 33 is fixedly coupled to the wheel 2, and the connection mechanism 4 is coupled to the pedal cover 33. The pedal cover 33 includes a first pedal cover 331 and a second pedal cover 332, the first pedal cover 331 is coupled to the left pedal 31, and the second pedal cover 332 is coupled to the right pedal 32.

The working principle is that the balance car 1 is a left-right symmetric structure, and the first and

second controllers

51 and 52 independently control the rotation of the two wheels. The first controller 51 acquires the tilt angle of the left pedal 31 collected by the sensor, and controls the first wheel 21 to increase or decrease speed. Similarly, the second controller 52 acquires the tilt angle of the right pedal 32 collected by the sensor, and controls the second wheel 22 to increase or decrease speed. When the two pedals are tilted in the same direction and at the same angle, the two wheels are at the same speed, and the car will go straight in the direction of the pedal rotation; when the two wheels have a difference in rotational speed, the turning function can be realized.

Also, a bridge device is provided around the wheel. The working principle is as follows: when the pedal rotates, the wheel will rotate in the same direction as the pedal. When the two pedals are inclined in the same direction and at the same angle, the car will go straight in the direction of the pedal rotation, when the angle of the pedals on both sides is not The same will result in a difference in the speed of the wheels on both sides to achieve the turning function.

Wherein, the middle portion of the connecting shaft 40 penetrates the center pedal 12, and the end portion of the connecting shaft 40 is connected to the side left pedal 311 and the side right pedal 321; specifically, the end of the connecting shaft 40 is inserted into the side left pedal 311, The side wall of the right side pedal 321 does not penetrate the side left pedal 311 and the side right pedal 321; thereby fixing the center pedal 12, the side left pedal 311, and the side right pedal 321 to the connection mechanism.
