In each of the scissors-shaped structures, an arm is connected to the rotating shaft 7, a lower end portion of the arm rotates about the rotating shaft 7, an upper end portion of the arm rotates about the corresponding rotating pin, and the support base 2 is lifted up, and at the same time, the footrest 3 is lifted up; for the other arm of each scissors-like structure, the lower end of the arm is turned around the corresponding turning pin, and the upper end is slid rightward along the guide groove 12 and lifts up the support stand 2, and at the same time, the footboard 3 is raised. In the process, the heights of the two upper end parts of each scissors-shaped structure are always kept consistent, and the heights of the two lower end parts are always kept consistent, so that the stability and the comfort of the support platform 2 and the pedal plate 3 are ensured.

When the pedal 3 needs to descend, the first motor driving component 4 is started, the rotating shaft of the first motor driving component 4 drives the third gear 10 to rotate clockwise, the first gear 8 is further driven to rotate anticlockwise, the first gear 8 drives the rotating shaft 7 to rotate anticlockwise, the second gears 9 at two ends of the rotating shaft 7 rotate anticlockwise, and at the moment, the two second gears 9 move leftwards along the corresponding first rack sliding rails 11 (the direction close to the main driving position is the left side, and the direction far away from the main driving position is the right side). In each scissors-shaped structure, an arm is connected with the rotating shaft 7, the lower end part of the arm rotates around the rotating shaft 7, the upper end part of the arm rotates around the corresponding rotating pin and drives the supporting platform 2 to move downwards, and meanwhile, the pedal 3 descends; for the other arm of each scissors-like structure, the lower end of the arm rotates around the corresponding pivot pin, and the upper end slides leftward along the guide groove 12 and brings the support base 2 to move downward, while the foot board 3 descends. In the process, the heights of the two upper end parts of each scissors-shaped structure are always kept consistent, and the heights of the two lower end parts are always kept consistent, so that the stability and the comfort of the support table 2 are ensured.

When the pedal 3 needs to move forward, the second motor driving assembly 14 is activated, and the rotating shaft of the second motor driving assembly 14 drives the fourth gear 15 to rotate counterclockwise along the second rack sliding rail 16. At this time, since the second motor driving assembly 14 is fixedly connected to the pedal 3, the second motor driving assembly 14 drives the pedal 3 to move forward (the direction of the front of the vehicle is forward, and the direction of the rear of the vehicle is backward). Meanwhile, the two guide blocks 172 of the bottom surface of the footboard 3 slide along the corresponding second guide ribs 171, respectively.

When the pedal 3 needs to move backward, the second motor driving assembly 14 is started, and the rotating shaft of the second motor driving assembly 14 drives the fourth gear 15 to rotate clockwise along the second rack sliding rail 16. At this time, since the second motor driving assembly 14 is fixedly connected to the pedal plate 3, the second motor driving assembly 14 drives the pedal plate 3 to move backward (the direction of the front of the vehicle is forward, and the direction of the rear of the vehicle is backward). Meanwhile, the two guide blocks 172 of the bottom surface of the footboard 3 slide along the corresponding second guide ribs 171, respectively.

It is understood that the lifting and the back-and-forth movement of the foot board 3 can be controlled separately, that is, when the foot board 3 is not required to be lifted and only needs to be moved back and forth, the user can activate only the second motor driving unit 14 and the foot board 3 can be moved back and forth. When the pedal 3 does not need to move back and forth and only needs to be lifted, a user can only start the first motor driving component 4, and the pedal 3 can be lifted. When the pedal 3 needs to be lifted and moved back and forth, the user can start the first motor driving component 4 and the second motor driving component 14 at the same time, and the pedal 3 can be lifted and moved back and forth.
