The movable mounting post is located the lower surface of second footboard, and simultaneously, the spring encircles the movable mounting post setting at second movable mounting hole, and second movable mounting hole is the non-perforating hole, and the one end of spring offsets with the diapire of second movable mounting hole. In other embodiments, the second movable mounting hole may be a through hole, and a protruding edge abutting against the spring is disposed at the bottom of the second movable mounting hole, so that the spring can extend and retract between the protruding edge and the second pedal 6, and the through hole in the second movable mounting hole may have other functions, such as facilitating maintenance of components in the second upper case or allowing contacts of other photoelectric switches to pass through.

In another embodiment, as shown in fig. 1 and 2, the second pedal 7 is disposed on the middle shell 50, the second photoelectric switch 601 is disposed on the second control board 5, the second control board 5 is located below the middle shell 50, the second contact 72 is disposed on the contact post 602 on the lower surface of the second pedal 7, as shown in fig. 9 and 10, the middle shell 50 is provided with a second contact through hole 502, the second contact 72 corresponds to the second photoelectric switch 601, and the second contact 72 passes through the second contact through hole 502 to trigger the second photoelectric switch 601. In order to enable the second pedal 7 to move up and down relative to the second upper shell 30 and the middle shell 50, a convex edge is arranged at the bottom of the second contact through hole 502, a spring is arranged above the convex edge, the spring is arranged in the second contact through hole 502, one end of the spring is abutted against the convex edge, and the other end of the spring is connected with a contact column 602 on the pedal and used for resetting the second pedal 7.

In another embodiment, as shown in fig. 5 and fig. 6, the second pedal 7 is disposed on the middle shell 50, the second photoelectric switch 601 is independently disposed on the middle shell 50 and located below the second pedal 7, the second photoelectric switch 601 is electrically connected to the second control board 5 through a connecting member and transmits an electrical signal, the second control board 5 is located below the middle shell 50, the second contact 72 is disposed on the lower surface of the second pedal 7, when the second pedal 7 is stood on or is stressed, the second photoelectric switch 601 is triggered by pressing the second pedal 7, and the signal is transmitted to the second control board 5 below the middle shell 50 to control the balance car to start working. More specifically, to fix the second photoelectric switch 601, the middle case 50 is provided with a mounting groove 603 for mounting the second photoelectric switch 601, and the second photoelectric switch 601 is placed in the mounting groove 603. Preferably, the depth of the mounting groove 603 is greater than or equal to the height of the second photoelectric switch 601, so as to avoid the second pedal 7 from being pressed and damaging the second photoelectric switch 601 when moving relative to the second upper shell 30; a third wire through hole 6033 is formed in the mounting groove 603 or on the side edge of the mounting groove 603, and the connecting piece penetrates through the third wire through hole 6033 to be connected with the second control plate 5. Meanwhile, in order to facilitate the second pedal 7 to reset after being pressed down, a movable mounting column for mounting a spring is arranged on the second pedal 7, as shown in fig. 16 and 17, a second movable mounting hole 503 is arranged on the middle shell 50, a through hole 302 for the second pedal 7 to pass through is arranged on the second upper shell 30, the movable mounting column is matched with the second movable mounting hole 503, one end of the spring is connected or abutted to the movable mounting column, the other end of the spring is connected or abutted to the second movable mounting hole 503, so as to realize the rebounding of the second pedal 7, the movable mounting column passes through the contact point hole 303, moves up and down in the second movable mounting hole 503, and drives the second pedal 7 to reset under the action of the spring. The movable mounting post is located on the lower surface of the second pedal 7, and the spring is disposed in the second movable mounting hole 503 around the movable mounting post. The movable mounting hole is a non-through hole, and one end of the spring is abutted to the bottom wall of the movable mounting hole. In other embodiments, the second movable mounting hole 503 may be a through hole, a protruding edge abutting against the spring is disposed at the bottom of the second movable mounting hole 503, so that the spring can extend and contract between the protruding edge and the second pedal 7, and the through hole in the second movable mounting hole 503 may have other functions, such as facilitating the maintenance of components in the middle shell 50 or allowing other contacts of the optoelectronic switch to pass through.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
