[0052] The following is a clear and complete description of the technical solution of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the present application provides a foldable scooter 100, which includes: a front leg unit 1, a rear leg unit 2, a central shaft 3, a seat unit 4, a backrest unit 5 and a folding unit 6. The foldable scooter 100 is relatively stable when folded.

[0054] The front foot unit 1 includes: a front body 11, a front wheel 12, a footrest 13 and a front rollover stopper 14. The front wheel 12 is located at the bottom end of the front body 11. Optionally, the front wheel 12 is a universal wheel or an omnidirectional wheel. The footrest 13 is arranged on the front body 11. For example, there are two front bodies 11, and the two front bodies 11 are symmetrically arranged. One end of the footrest 13 is connected to the first front body, and the other end of the footrest 13 is connected to the second front body. The front rollover stopper 14 is arranged at the bottom end of the footrest 13. Optionally, the front rollover stopper 14 is connected to the footrest 13 by welding, and the front rollover stopper 14 is a pipe fitting formed by bending a metal pipe.

[0055] like Figure 5As shown, the rear foot unit 2 includes: a rear body 21, a rear wheel 22 and an anti-rear rollover wheel 23. The rear wheel 22 is arranged at the bottom end of the rear body 21. Optionally, the rear foot unit 2 also includes a motor, which is used to drive the rear wheel 22 to rotate. The anti-rear rollover wheel 23 is arranged on the rear body 21. For example, the number of the rear body 21 is two, and the two rear body 21 are symmetrically arranged, and the anti-rear rollover wheel 23 is arranged between the two rear body 21 through a support frame.

[0056] The central shaft 3 is connected to the front body 11 and the rear body 12 respectively. For example, the top of the front body 11 and the top of the rear body 12 are connected to the central shaft 3 respectively, so that the front body 11 and the rear body 12 are pivotally connected.

[0057] The seat unit 4 is deployed for the user to sit on. The seat unit 4 is pivotally connected to the front vehicle body 11 and / or the rear vehicle body 21. For example, the seat unit 4 is pivotally connected to the top end of the front vehicle body 11, or the seat unit 4 is pivotally connected to the top end of the rear vehicle body 21, or the seat unit 4 is pivotally connected to the front vehicle body 11 and the rear vehicle body 21.

[0058] The backrest unit 5 is unfolded for the user to lean on. The backrest unit 5 includes a backrest 51, which is pivotally connected to the seat unit 4 so that the backrest 51 can be folded or unfolded. For example, when folded, the top end of the backrest 51 rotates toward the direction close to the seat unit 4, and when unfolded, the top end of the backrest 51 rotates away from the seat unit 4.

[0059] The folding unit 6 is disposed on the rear vehicle body 21, and the folding unit 6 is pivotally connected to the seat unit 4 and / or the backrest unit 5.
