[0044] This utility model provides a foldable electric mobility scooter, including a body assembly 1, a handlebar assembly 2, a seat assembly 3, a front wheel assembly 4, a rear wheel assembly 5, and a locking adjustment component 6. The lower front end of the body assembly 1 is connected to the front wheel assembly 4, and the lower rear end of the body assembly 1 is connected to the rear wheel assembly 5. The connecting end of the front wheel assembly 4 passes through the body assembly 1 and is connected to the handlebar assembly 2 via the locking adjustment component 6. The locking adjustment component 6 can change the orientation of the handlebar assembly 2. The seat assembly 3 is rotatably connected to the body assembly 1 and includes a folded state and an upright state. This utility model provides a foldable electric mobility scooter. By adjusting the locking adjustment piece 6, the handlebar assembly 2 can rotate relative to the body assembly 1, and the seat assembly 3 can also be folded. The process from the use state to the folded state is as follows: first, rotate the seat assembly 3 towards the handlebar assembly 2 until the seat assembly 3 is parallel to the body assembly 1. Then, loosen the locking adjustment piece 6, causing the handlebar assembly 2 to rotate towards the seat assembly 3 until the handlebar assembly 2 is parallel to the body assembly 1 and the handlebar assembly 2 presses against the seat assembly 3. Finally, tighten the locking adjustment piece 6 to fix the handlebar assembly 2, which in turn restricts the seat assembly 3. This reduces the overall height of the foldable electric mobility scooter, making it easier to store and reducing the storage space required. This solves the technical problem of existing mobility scooters that cannot be folded and stored, and that take up a lot of space when placed.

[0045] As an optional implementation, the handlebar assembly 2 is a one-piece carbon fiber handlebar. The handlebar assembly 2 includes an operating handlebar 21, a retaining sleeve 22, and a display unit 23. The lower end of the display unit 23 is fixedly connected to the retaining sleeve 22, the middle part of the operating handlebar 21 is connected to the display unit 23, and the other end of the retaining sleeve 22 is connected to the locking adjustment member 6. That is, the retaining sleeve 22 is fitted onto the second extension shaft 621, and the retaining sleeve 22 and the second extension shaft 621 are connected by bolts. The display unit 23 is equipped with a display panel, an NFC element, and a brake lever. The display panel is an LCD screen. According to the user's habits, the orientation of the handlebar assembly 2 can be adjusted via the locking adjustment member 6, thus changing the angle between the handlebar assembly 2 and the vehicle body assembly 1.

[0046] As an optional implementation, the front wheel assembly 4 includes a front wheel structure 41, a connecting frame 42, a first transmission structure 43, a connecting plate 44, a rotating sleeve 45, and a support frame 46.

There are two front wheel structures 41, two connecting frames 42, and two first transmission structures 43. The connecting frame 42 can be a U-shaped structure. The two connecting frames 42 are rotatably connected to both ends of the support frame 46. The front wheel structure 41 is connected to the middle area of ​​the corresponding connecting frame 42. The rotating sleeve 45 passes through the hollow sleeve on the support frame 46. The upper end of the rotating sleeve 45 is connected to the locking adjustment member 6, and the lower end of the rotating sleeve 45 is connected to the front end of the connecting plate 44. The rear end of the connecting plate 44 is connected to the connecting frame 42 through the first transmission structure 43. When the foldable electric mobility scooter makes a turn, the user turns the handlebar assembly 2 left or right, which causes the rotating sleeve 45 to rotate relative to the hollow sleeve, thereby driving the connecting plate 44 to rotate, which in turn drives the first transmission structure 43 to move, and then causes the two front wheel structures 41 to rotate in the same direction.

[0047] As an optional implementation, the locking adjustment member 6 includes a first toothed disc 61, a second toothed disc 62, an elastic member, and a knob 63.

[0049] The first gear 61 has multiple first mating teeth on its end face, and the second gear 62 has multiple second mating teeth on its end face. The first mating teeth can mesh with the second mating teeth. When the knob 63 is tightened, the distance between the first gear 61 and the second gear 62 is close, causing the first and second mating teeth to mesh. At the same time, the elastic element is compressed, and the first gear 61 and the second gear 62 cannot rotate relative to each other, thus restricting the rotation of the handlebar assembly 2. When the knob 63 is loosened, the first gear 61 and the second gear 62 will separate under the compressive force of the elastic element, that is, the first and second mating teeth will separate. At this time, the first gear 61 and the second gear 62 can rotate relative to each other, and thus the handlebar assembly 2 can rotate.
