[0019] Example 1

[0020] See Figure 1, an electric scooter pedal, comprising a scooter body 1 and a pedal box 2, pedal boxes 2 are provided on both sides of the scooter body 1, the scooter body 1 and the pedal box 2 are connected by a screw transmission mechanism 20, the scooter body 1 and the pedal box 2 are connected by a positioning sliding mechanism 30, the screw transmission mechanism 20 comprises two screws 3, the screws 3 are rotatably mounted on both sides of the scooter body 1, a moving nut 4 is threadedly mounted on the screw 3, the moving nut 4 is fixedly connected to the pedal box 2, a resistance structure 8 is provided on the positioning sliding mechanism 30, and the resistance increases when the pedal box 2 moves to the set position; The positioning sliding mechanism 30 includes a sliding bearing 5 and a sliding rod 6. The sliding rod 6 is installed on the scooter body 1. Sliding bearings 5 are slidably installed on both sides of the sliding rod 6. The sliding bearings 5 are connected to the pedal box 2. The resistance structure 8 is set at the end of the sliding rod 6. When the sliding bearing 5 moves to the position of the resistance structure 8, the resistance it encounters increases; the resistance structure 8 is a retaining spring; an accelerator pedal 10 is installed on one of the pedal boxes 2, and a Hall element 11 is provided on the accelerator pedal 10. A permanent magnet 12 matching the Hall element 11 is provided on the accelerator pedal box 2, and the Hall element 11 is connected to the electronic control unit.

[0021] The two screws 3 of this embodiment are driven by independent drive motors, which need to be calibrated through a program during use so that the left and right pedals are synchronized during the next operation; the drive motor is driven by a battery, and the forward and reverse rotation of the motor is controlled by a switch, which corresponds to the extension and retraction of the pedals.

[0022] Example 2

[0023] See Figures 2 to 5 The number of the screw rod 3 is one, and the spiral directions of the left and right ends of the screw rod 3 are opposite, forming a bidirectional screw. The bidirectional screw is driven to rotate by the drive motor 9. A rotating gear is provided on the bidirectional screw, and the rotating gear is engaged with the drive gear at the output end of the drive motor 9. The rest is the same as Example 1.

[0024] Example 3

[0025] The resistance structure 8 is provided at the end of the screw rod 3 , and the resistance encountered by the movable nut 4 increases when the movable nut 4 moves to the position of the resistance structure 8 . Other aspects are the same as those of the first embodiment.

[0026] There are three ways to set up the resistance structure: adding a retaining spring; thickening the part to form a thickened section; and increasing the friction force of the part to form a rough section.

[0027] During operation, the pedal box reaches the preset position and is resisted by the resistance structure, making it unable to continue to move forward. The resistance from the left and right ends causes the motor's screw to be blocked at this position, driving the motor to rotate. The current increases accordingly. When the current is greater than the set value, a signal is obtained that the pedal has reached the left or right end, and the motor stops rotating, achieving automatic stop of the pedal when it reaches the left or right end.

[0028] The acceleration / deceleration electronic brake function is realized by the accelerator pedal. When the position of the accelerator pedal changes, the relative position of the permanent magnet and the Hall element changes.

[0029] When the pedal is not depressed, the Hall element is in an initial magnetic field environment; as the pedal is depressed, the magnetic field strength changes; according to the Hall effect, the Hall element generates a Hall voltage proportional to the change in magnetic field strength when the magnetic field changes; the electronic control unit ECU receives this signal and calculates the corresponding acceleration requirement; then, the ECU controls the motor power so that the vehicle speed can rise or fall at a corresponding uniform speed; as the pedal depression depth gradually increases, the Hall voltage also gradually increases. After processing, the ECU will allow the power system to increase the output smoothly, so that the vehicle speed increases at a uniform speed; as the pedal depth gradually decreases, the vehicle speed will also decrease at a corresponding uniform speed.

[0030] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
