The height of rear wheel 22 hubs and the ratio of diameter are 2: 1, make the front and rear center of gravity of scooter keep balance.

The working principle of this foot-controlled electric scooter:

Direction control device: when driving straight, the driver's feet are placed on the foot contour placement device 23 . When the driver needs to turn to the left, the heel of the left foot steps on the friction stripes of the foot profile placement device 23, and the toe moves to the left direction pedal 1 with the heel as the center of circle. When stepping on the left direction pedal 1, the force is transmitted to the left rack 6, the left rack 6 slides downward, and the return spring 20 on the left is compressed. The left rack 6 meshes with the left gear 7, the left gear 7 meshes with the middle gear 9 to rotate, the middle gear 9 meshes with the right gear 11 to rotate, the right rack 13 meshes with the right gear 11 and slides upward, and the return spring 20 on the right is stretched . The steering gear 14 drives the steering rack 15 to slide horizontally to the left, and the steering control rod 16 drives the rotating sleeve 18 to rotate counterclockwise around the positioning sleeve 29 through the rotating sleeve connecting rod 17, so that the two front wheels 19 rotate to the left, and the scooter Make a left turn. In the process of turning to the left, the amount of compression of the return spring 20 on the left side is the same as the stretching amount of the return spring 20 on the right side. The left direction pedal 1 and the right direction pedal 2 return to their original positions under the action of the corresponding back-moving spring 20, and the scooter continues to travel straight ahead. In the same way, when the driver needs to turn right, the heel of the right foot steps on the friction stripes of the foot contour placement device 23, and the toes move to the right direction pedal 2 with the heel as the center of circle. When stepping on the right direction pedal 2, the power is transmitted to the right rack 13, and the return spring 20 on the right side is compressed. The right rack 13 meshes with the right gear 11, the right gear 11 meshes with the middle gear 9 to rotate, the middle gear 9 meshes with the left gear 7 to rotate, the left rack 6 meshes with the left gear 7 and slides upward, and the return spring 20 on the left is stretched . The steering gear 14 drives the steering rack 15 to slide horizontally to the right, and the steering control rod 16 drives the rotating sleeve 18 to rotate clockwise around the positioning sleeve 29 through the rotating sleeve connecting rod 17, so that the two front wheels 19 rotate to the right, and the scooter Make a right turn. During the right steering process, the compression amount of the return spring 20 on the right side is the same as the stretching amount of the return spring 20 on the left side. The left direction pedal 1 and the right direction pedal 2 return to their original positions under the action of the corresponding back-moving spring 20, and the scooter continues to travel straight ahead.

Power acceleration device: during normal driving, the driver's both feet are placed on the foot contour placement device 23 . When the scooter accelerated, the driver's right heel stepped on the friction stripes of the foot profile placement device 23, and the toe moved to the speed change pedal 3 with the heel as the center of circle. When the speed change pedal 3 is stepped on, the push rod 31 slides downward along the push rod sleeve 28, the return spring 27 is compressed, and the contact switch 30 is activated; when the push rod 31 slides downward along the push rod sleeve 28 to the maximum stroke During the process, the resistance value of the sliding rheostat changes from large to small, the current in the control circuit changes from small to large, and the speed of the hub motor becomes faster, realizing the acceleration process. When the scooter finishes accelerating, the driver lifts the right foot and moves back on the foot profile placement device 23, and the restoring force of the return spring 27 promotes the pedal support block 26 and the speed change pedal 3 to return to the initial height automatically. The driver can control the degree of acceleration of the scooter according to the strength of the right foot stepping on the speed change pedal 3 .

Deceleration and braking device: during normal driving, the driver's both feet are placed on the foot contour placement device 23 . When the scooter decelerates or brakes, the driver's left heel steps on the friction stripes of the foot contour placement device 23, and the toe moves to the speed change pedal 3 with the heel as the center of circle. When the shift pedal 3 is depressed, the return spring 27 is compressed, and the contact switch 30 is activated. When the push rod 31 slides down to the maximum stroke along the push rod sleeve 28, the displacement sensor detects that the push rod 31 slides downward. According to the position information of the speed change pedal 3, the control circuit outputs a PWM signal, and according to the change of the rotor Hall position signal of the in-wheel motor, the conduction sequence of "three-phase six-step" is selected, and the conduction phase The corresponding IGBT power tube outputs a reverse current. The longer the IGBT power tube is turned on, the greater the value of the reverse current, and the slower the rotation speed of the hub motor, realizing the deceleration process. The driver can output a PWM signal to control the size of the reverse current according to the strength of stepping on the speed change pedal 3 with the left foot. When the driver needs to slowly decelerate the scooter, he only needs to step on one-third of the speed change pedal 3, the IGBT power tube conduction time is shorter, and the reverse current output by the control circuit is smaller; When the scooter decelerates rapidly, two-thirds of the speed change pedal 3 can be stepped on, the IGBT power tube conduction time is relatively long, and the control circuit outputs a large reverse current to achieve rapid deceleration; when the driver needs to make the scooter When braking immediately, you can step on the variable speed pedal 3 to the maximum stroke, and the IGBT power tube will be turned on until the scooter stops, and the control circuit will output the rated maximum reverse current to realize immediate braking.
