A pusher 32 is slidably mounted inside the adjustment box 25 and below the adjustment support 33. The pusher 32 is used to push the adjustment support 33 to adjust the extension and retraction of the spring 31.

[0032] The pedal mechanism includes a motor 23 and a lead screw 24 located at the front end of the base 1 and on both sides of the pedal mounting seat 8. The motor 23 drives the lead screw 24. The lead screw 24 and the pedal mounting seat 8 form a helical pair. Limiting grooves 26 are provided on both sides of the pedal mounting seat 8 to limit the pedal 9. A brake cylinder 28 is provided at the bottom of the pedal mounting seat 8. A push wheel 27 is provided on the extension rod of the brake cylinder 28.

The cleaning section 21 is used to remove impurities adhering to the induction magnet 901. A magnetic detector 18 is used to detect the magnetism of the induction magnet 901.

[0034] The principle of this invention is as follows: When folding, one pin 5 can be removed to flip the handle 7 and complete the folding. Removing both pins 5 completes the disassembly. Power output is achieved through foot pedal action. Specifically, by pressing the pedal 9, the pedal 9 deflects. The Hall sensor 22 detects the position of the sensing magnet 901 and thus detects the deflection of the pedal 9 to control the power output. Furthermore, the tightness of the pedal 9 can be adjusted. Different users have different driving habits, so the tightness of the pedal 9 can be adjusted. Specifically, by adjusting the operation of the motor 29, the adjusting rod 30 rotates, which moves the push seat 32. The push seat 32 pushes the adjusting support seat 33, thereby adjusting the compression of the spring 31 to complete the adjustment.

[0035] When pedal 9 is pressed, the limiting shaft 903 on the side of pedal 9 moves in the limiting groove 26, which limits the deflection stroke; the return spring 904 is compressed, providing elastic force for reset; further, when the connecting shaft 902 follows the deflection of pedal 9, the linkage slide 35 slides under the connection of the connecting rod 34, and the spring 31 is compressed, thereby realizing linkage, that is, adjusting the compression of spring 31 can realize the adjustment of the pressure of pedal 9; when the vehicle system detects that the speed is too fast and performs emergency braking, the brake cylinder 28 controls the push wheel 27 to support the pedal 9 and rebound, interrupting the power output. Emergency braking is existing technology and will not be described in detail here.

[0036] During maintenance, the induction magnet 901 can be inspected and cleaned. Specifically, by operating motor 23, the lead screw 24 rotates, causing the pedal mounting base 8 to move. Motor 13 controls the deflection of the baffle 11, so that the maintenance box 10 is open. The pedal mounting base 8 drives the pedal 9 to move, extending the pedal 9 into the maintenance box 10. The cleaning unit 21 and the magnetic detector 18 are located below the induction magnet 901. By operating motor 12, the lead screw 15 rotates, causing the slide 16 to move, i.e., the mounting platform 19 moves. By operating cleaning motor 20, the cleaning unit 21 rotates, and the control cylinder 17 controls the height of the mounting platform 19. The cleaning unit 21 removes impurities adhering to the surface of the induction magnet 901, ensuring normal sensing with the Hall sensor 22. Furthermore, the magnetic properties of the induction magnet 901 can be detected by the magnetic detector 18 for timely replacement and maintenance.
