[0021] See also Figure 1-4 As shown, the utility model provides a technical solution:

[0022] A foldable electric scooter includes a pedal frame 1, a rear wheel 2 is installed at the tail of the pedal frame 1, the front end of the pedal frame 1 is rotatably connected to the wheel frame 3, the lower part of the wheel frame 3 is provided with a front wheel 4, the upper end of the wheel frame 3 is rotatably connected to the folding tube 5 through a hinge 9, the front side of the lower end of the folding tube 5 is fixedly provided with a connecting ear 51, the upper end of the folding tube 5 is fixedly provided with a handle 8, the top of the pedal frame 1 on the front side of the wheel frame 3 is fixedly connected to an arc-shaped support plate 6, the inner diameter of the arc-shaped support plate 6 is the same as the outer diameter of the folding tube 5, the arc-shaped support plate 6 is provided with a through slot 61, and the front side of the arc-shaped support plate 6 above the through slot 61 is fixedly connected to a lock box 7 When the bolt 71 is in the unlock position, the latch 7 is locked and the latch is in the unlocked position, and the locking nut 77 is locked. When the bolt 71 is unlocked, the latch 7 is locked and the locking nut 77 is locked. The bolt 77 is in the unlocked position, and the locking nut 77 is locked. When the bolt 71 is unlocked, the latch 7 is locked and the locking nut 77 is locked. By folding the hinge 9 and clamping the folding tube 5 in the elastic arc clamp 101, the folding tube 5 can be quickly limited and fixed, making the electric scooter more stable when being carried and moved, and there is no need to use a strap to tie the folding tube 5 to the pedal frame 1, which makes the operation more convenient. When the folding tube 5 needs to be folded, one hand can pull the pull ring 73 upward to drive the lock tongue 71 to move upward to compress the spring 74, so that the lower end of the lock tongue 71 moves out of the connecting ear 51. At this time, the other hand can be used to rotate the folding tube 5 downward around the hinge 9 and use a certain force to clamp the folding tube 5 in the elastic arc clamp 1 01, the folding and fixing of the folding tube 5 can be completed. When the folding tube 5 needs to be unfolded, the folding tube 5 is first taken out from the elastic arc card 101, and then the pull ring 73 is manually pulled upward to compress the spring 74. Then, the folding tube 5 is manually rotated upward around the hinge 9 to make the connecting ear 51 pass through the through groove 61 and make the folding tube 5 stick to the inner wall of the arc support plate 6. Finally, the pull ring 73 is released. At this time, under the elastic force of the spring 74, the lock tongue 71 can be driven to move downward, so that the lower end of the lock tongue 71 passes through the connecting ear 51, the folding tube 5 is locked, and the rapid unfolding of the folding tube 5 can be completed.

[0023] The fixed support 10 is fixedly connected to the pedal frame 1 by a bolt 13. A mounting groove 11 is provided on the pedal frame 1 at the rear side of the wheel frame 3. The lower part of the fixed support 10 is installed in the mounting groove 11. Connecting slides 12 are symmetrically provided on both sides of the mounting groove 11. Connecting sliders 102 are symmetrically provided on both sides of the lower part of the fixed support 10. The connecting sliders 102 are connected with the connecting slides 12. A rectangular through hole is provided in the middle of the fixed support 10. The lower end of the bolt 13 passes through the bottom of the fixed support 10 and is screwed into the threaded hole provided at the bottom of the mounting groove 11. By unscrewing the bolt 13, the fixed support 10 can be removed from the pedal frame 1, and the damaged fixed support 10 can be replaced, which has a better use effect. After a period of use, when the elastic arc clip 101 on the fixed support 10 is damaged, the bolt 13 can be unscrewed from the pedal frame 1, and the fixed support 10 can be slid backward out of the mounting groove 11, and then the new fixed support 10 is aligned and slid into the mounting groove 11, and finally the bolt 13 is passed through the fixed support 10 and screwed into the pedal frame 1 to complete the quick replacement of the fixed support 10.

[0024] Working principle: When in use, when the folding tube 5 needs to be folded, the pull ring 73 can be pulled up by one hand to drive the lock tongue 71 to move upward to compress the spring 74, so that the lower end of the lock tongue 71 is removed from the connecting ear 51. At this time, the folding tube 5 can be rotated downward around the hinge 9 with the other hand, and the folding tube 5 can be clamped in the elastic arc clamp 101 with a certain force to complete the folding and fixing of the folding tube 5. When the folding tube 5 needs to be unfolded, the folding tube 5 is first taken out of the elastic arc clamp 101, and then the pull ring 73 is manually pulled up to compress the spring 74, and then the folding tube 5 is manually rotated upward around the hinge 9 to make the connecting ear 51 pass through the through slot 61 and the folding tube 5 is unfolded. The stacked tube 5 is attached to the inner wall of the arc-shaped support plate 6, and finally the pull ring 73 is loosened. At this time, under the elastic force of the spring 74, the locking tongue 71 can be driven to move downward, so that the lower end of the locking tongue 71 passes through the connecting ear 51, locking the folding tube 5, and completing the rapid deployment of the folding tube 5. After a period of use, when the elastic arc card 101 on the fixed support 10 is damaged, the bolt 13 can be unscrewed from the pedal frame 1, and the fixed support 10 can be slid backward out of the mounting groove 11, and then the new fixed support 10 is aligned and slid into the mounting groove 11, and finally the bolt 13 passes through the fixed support 10 and is screwed into the pedal frame 1, and the rapid replacement of the fixed support 10 can be completed.
