Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a portable folding vehicle, including a folding mechanism 1, a support mechanism 2 and a driving mechanism 3. The folding mechanism 1 includes a seat 4 and a rotating mechanism 5. The support mechanism 2 includes a fixed seat 6 and a foot pad 26. The driving mechanism includes an electric motor 7, two rear wheels 8 and a front wheel 9. The rotating mechanism 5 includes a first rotating gear 10, a second rotating gear 11 and a driven wheel 12 that cooperates with the first rotating gear 10. The seat 4 is connected to the first rotating gear 10 through a fixed rod 13. The second rotating gear 11 is connected to the electric motor 7. The fixed seat 6 is fixedly connected to both sides of the rotating mechanism 5. The foot pad 26 is connected to the driven wheel 12 through a first telescopic lever 14. The two rear wheels 8 are connected to the second rotating gear 11 through a second telescopic lever 15. A direction control lever 16 is provided on the front wheel 9. The direction control lever 16 includes an operating platform 17, a third telescopic lever 18 and a rotating shaft 19. A traction motor 20 is also provided on the front wheel 9.

[0024] Specifically, the driven wheel 12 is set as a semi-circular gear. The first rotating gear 10 and the driven wheel 12 are meshed and connected. By setting the semi-circular driven wheel 12, it can better cooperate and connect with the first rotating gear 10, so as to ensure that the seat 4 is more stable and smooth during the folding and unfolding process. To further improve the portability of the folding vehicle.

[0025] Specifically, a cushion 21 is fixedly connected to the seat 4. By providing the cushion 21, the user will feel more comfortable when using it, ensuring that they will not feel tired even during long rides.

[0026] Specifically, the drive mechanism 3 further includes a drive battery 22, which is arranged below the fixed seat 6. By providing the drive battery 22 and installing it below the fixed seat 6, the center of gravity of the folding bike is lowered, thereby improving the overall stability of the vehicle. The drive battery 22 can use a high-capacity lithium battery to ensure that the folding bike has a longer battery life.

[0027] Specifically, a lifting handle 23 is provided at the bottom of the seat 4. By providing the lifting handle 23 at the bottom of the seat 4, when the seat 4 is folded, the lifting handle 23 can be pulled out to drag the entire folding bike like a suitcase, greatly improving the mobility of the folding bike. In addition, the design of the lifting handle 23 also makes it easier for users to carry the folding bike and avoids discomfort caused by long-term carrying.

[0028] Specifically, a protective plate 24 is provided on the footrest 26. By providing the protective plate 24, users will not get their shoes or clothes soiled by the mud and gravel splashed by the front wheel 9 during riding, thereby improving the comfort and cleanliness of riding.

[0029] Specifically, a pulley 25 is provided at the bottom of the fixed seat 6, and the pulley 25 is connected to the rear wheel 8 through a lever. By providing the pulley 25, when the folding bike is folded and dragged like a suitcase, it can slide through the pulley 25.

[0030] Specifically, the traction motor 20 is directly or connected to the front wheel 9 through a belt or gear drive. With the above settings, the traction motor 20 can operate independently of the electric motor 7 to provide additional power for the front wheel 9. In this way, when going uphill or encountering a difficult-to-drive road surface, the traction motor 20 can provide additional thrust to ensure that the folding bike travels more smoothly and stably.

[0031] A specific application example of this embodiment is:

[0032] When this folding bike needs to be folded, it is driven by an electric motor 7, which drives the first rotating gear 10 and the second rotating gear 11. The seat 4 is turned and folded, the rear wheel 8 is telescopically folded through the second telescopic lever 15, the front wheel 9 and the steering lever 16 are both telescopically folded through the third telescopic lever 18. Then, the footrest 26 is telescopically folded through the first telescopic lever 14. After folding, it presents a structure of a suitcase. The rear wheel 8 is folded to both sides of the fixed seat 6, and the front wheel 9 is folded to the middle of the fixed seat 6. The lifting handle 23 can be pulled out, and the folded bike can be dragged through the pulley 25. When it is necessary to ride, it is also driven by the electric motor 7. The seat 4 turns back to its original position, the rear wheel 8 extends through the second telescopic lever 15, the front wheel 9 and the steering lever 16 both extend through the third telescopic lever 18. At the same time, the footrest 26 extends through the first telescopic lever 14, and then it can be ridden. The riding work is carried out through the drive mechanism and the drive battery 22.
