[0043] Specifically, the multifunctional electric scooter described in this embodiment has two riding states, namely, a standing mode and a sitting mode, by rotating the middle pole 12 and the front pole 11; when in the sitting mode, the user sits on top of the middle pole 12, and when in the standing mode, the middle pole 12 is located directly in front of the user; in addition, the middle pole 12 and the rear pole 13 can be rotated so that the middle pole 12 and the rear pole 13 can be folded for easy storage; thus, the electric scooter of this embodiment has multiple functions.

[0044] In addition, by providing the electronic brake switch 341, the front brake assembly and the rear brake assembly, the electric scooter has a variety of braking methods; secondly, by providing the buffer assembly, a buffering effect can be achieved.

[0045] In addition, when in use, the connecting wire of the electronic brake switch 341 of the handlebar seat 111 and the rear brake wire 345 enter the front cavity 113 and are wired downward along the outer wall of the steering sleeve 14 until they reach the position of the wire hole 143, enter the steering cavity 141 through the wire hole 143, and enter the middle cavity 121 from the wire hole 151 of the rotating shaft 15; the connecting wire of the hub motor 313 and the front brake wire 344 enter the front cavity 113 and are wired upward along the outer wall of the steering sleeve 14 until they reach the position of the wire hole 143, enter the steering cavity 141 through the wire hole 143, and enter the middle cavity 121 from the wire hole 151 of the rotating shaft 15.

[0046] In this embodiment, by providing a steering sleeve 14, various wires can be routed along the outer wall of the steering sleeve 14, reducing the contact area between the various wires and the steering rod 142, preventing the steering rod 142 from constantly rubbing against the various wires during rotation, thereby damaging the connecting wires; in addition, various wires enter the steering cavity 141 through the wire hole 143 of the rotating shaft 15, so that the various wires can be arranged, and at the same time, the various wires will not be entangled when switching between the sitting state and the standing state, thereby increasing the stability of the overall structure.

[0047] In a multifunctional electric scooter of this embodiment, the two ends of the threading hole 151 are respectively connected to the steering cavity 141 and the middle cavity 121; the steering sleeve 14 is provided with a tilting rod 16; the other end of the rotating shaft 15 is rotatably arranged on the tilting rod 16; the tilting rod 16 is arranged on one side of the steering sleeve 14; the threading hole 143 is arranged on the other side of the steering sleeve 14.

[0048] Specifically, in this embodiment, by providing the tilting rod 16 , the middle rod 12 forms a dual-use state of a sitting state and a standing state during the process of rotating along the tilting rod 16 .

[0049] In the multifunctional electric scooter of this embodiment, a wire groove 123 is provided in the middle cavity 121 along the length direction. The above arrangement can be used to organize the connecting wires.

[0050] In the multifunctional electric scooter of this embodiment, a first thrust bearing 152 is provided between the other end of the rotating shaft 15 and the tilting rod 16. Through the above arrangement, the rotating shaft 15 can stably rotate in the tilting rod 16.

[0051] In the multifunctional electric scooter of this embodiment, the other end of the rotating shaft 15 is threadedly connected with a locking nut 153; the locking nut 153 is used to tighten the first thrust bearing 152 in the tilt rod 16.

[0052] In the multifunctional electric scooter of this embodiment, a retaining spring 154 is provided at the other end of the rotating shaft 15; the locking nut 153 is provided between the retaining spring 154 and the first thrust bearing 152. Through the above arrangement, the stability of the connection between the locking nut 153 and the rotating shaft 15 can be enhanced, and the locking nut 153 and the first thrust bearing 152 can be prevented from being separated during the rotation of the rotating shaft 15.

[0053] In the multifunctional electric scooter of this embodiment, a conversion seat 17 is provided at one end of the middle pole 12; one end of the rotating shaft 15 is fixedly provided at the conversion seat 17; the rotating shaft 15 is provided through the conversion seat 17; and the conversion seat 17 is detachably connected to the tilting rod 16.
