Adopting the above-mentioned technical solution, the pedal 310 is mainly arranged on the outside of the driving wheel assembly 200, and the vehicle body 100 is arranged between the two driving wheel assemblies 200. Compared with the prior art, the space occupied by the two control boards 320 is reduced. Small, and the pedals 310 are located on the outside of the two driving wheel assemblies 200. After the pedals 310 are stressed, the signal of the movement trend generated can be driven by the pedals 310 to tilt the vehicle body 100 to generate a rotation signal and transmit it to the control board 320, or it can be transmitted to the control board 320 by The pedal 310 generates an inclination and directly transmits the rotation signal to the control board 320. In a specific application, at least one side of the movement trend signal is generated by the pedal 310 and directly transmits the rotation signal to the control board 320, and each pedal on both sides 310 can only accommodate one foot to stand immediately, the stepping area of the pedal 310 is small, and its own gravity and required cost are reduced; in this way, for the car body 100, the plane coverage size of the balance car can be reduced, so that the car body 100 The processing is simpler and the cost is lower; the pedals 310 are arranged on both sides of the driving wheel assembly 200, and it is easier to control the balance of the self-balancing vehicle.

In some embodiments, the vehicle body 100 is an arc-shaped structure, and the end of the vehicle body 100 is slightly inclined at an angle. At this time, when the driving wheel assembly 200 is installed on the vehicle body 100, the plane where the driving wheel assembly 200 is located is in line with the The ground is at an angle, which improves the stability of the rider to a certain extent while riding.

Specifically, please refer to Fig. 1-2, the vehicle body 100 includes the connected first plate body 110, the second plate body 120 and the third plate body 130, the above-mentioned first plate body 110, the second plate body 120 and the third plate body The body 130 is a flat plate structure, and the above-mentioned first plate body 110, second plate body 120 and third plate body 130 are connected as one body along the length direction. An angle is formed between the bodies 120, so that when the driving wheel assembly 200 is installed on the first plate body 110 or the third plate body 130, an angle will be formed between the driving wheel assembly 200 and the ground, specifically shown as being in The driving wheel assemblies 200 at both ends of the vehicle body 100 are inclined towards each other, so as to improve the stability of the self-balancing vehicle during operation.
