[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0029] Figures 1-5As shown, the folding structure of the electric scooter's upright includes an upright 1 and a connecting seat 4 located at the front end of the scooter's footboard. A rotating seat 3 is provided at the bottom end of the upright 1, and the rotating seat 3 is rotatably connected to the connecting seat 4. A fixing block 5 is provided between the rotating seat 3 and the connecting seat 4. The two ends of the fixing block 5 can be connected to the connecting seat 4 and the rotating seat 3 respectively. The two ends of the fixing block 5 are bent to provide insertion parts 6. The connecting seat 4 and the rotating seat 3 are respectively provided with a first slot 16 and a second slot 7. The insertion parts 6 are inserted into the first slot 16 and the second slot 7. When the connecting seat 4 and the rotating seat 3 are in contact with each other, the two insertion parts 6 are simultaneously inserted into the first slot 16 and the second slot 7 respectively.

[0030] Figures 2-5 As shown, when the electric scooter is unfolded from its folded state, the upright tube 1 is rotated. At this time, the upright tube 1 drives the rotating seat 3 to rotate around the connecting seat 4 until the connecting seat 4 and the rotating seat 3 are in contact with each other. Then, the insertion part 6 is inserted into the first slot 16 and the second slot 7 respectively. At this time, the fixing block 5 and the insertion part 6 can fix the connecting seat 4 and the rotating seat 3 together, thereby preventing the rotating seat 3 from rotating during the use of the electric scooter and affecting its use.

[0031] Figures 2-7 As shown, a knob 2 is provided on the fixing block 5. After passing through the fixing block 5, the knob 2 is threadedly connected to the connecting seat 4 or the rotating seat 3. A locking block 10 is provided inside the connecting seat 4 or the rotating seat 3. After passing through the fixing block 5 and the connecting seat 4 / rotating seat 3, the knob 2 is threadedly connected to the locking block 10. The fixing block 5 is tightened by the knob 2 to fix the connecting seat 4 and the rotating seat 3.

[0032] Figures 2-7 As shown, after the insertion part 6 is inserted into the first slot 16 and the second slot 7 respectively, the knob 2 is rotated so that the knob 2 passes through the fixing block 5 and the connecting seat 4 / rotating seat 3 and is threadedly connected to the locking block 10, thereby fixing the fixing block 5 and preventing it from sliding during the use of the electric scooter. This design serves to fix the fixing block 5.

[0033] Figures 2-9 As shown, the connecting seat 4 is also provided with a spring pin 8. The connecting seat 4 has a threaded hole 13, and a sleeve 14 is screwed into the threaded hole 13. A spring 11 is provided between the spring pin 8 and the sleeve 14. The spring pin 8 passes through the sleeve 14, and the spring 11 always provides the spring pin 8 with a force to push out the sleeve 14. The rotating seat 3 has an insertion hole 15. After the spring pin 8 passes through the connecting seat 4, it can be inserted into the insertion hole 15.

[0034] Figures 2-9As shown, when the connecting seat 4 and the rotating seat 3 are in contact with each other, the deformed spring 11 can push the spring pin 8 to slide inside the sleeve 14 and insert it into the socket 15, further reinforcing the connecting seat 4 and the rotating seat 3, thereby preventing the rotating seat 3 from sliding during the use of the electric scooter. This design effectively improves the fixing effect, making the electric scooter safer and more stable during use.

[0035] Figures 2-9 As shown, when disassembly is required, the spring pin 8 is pulled outward. At this time, the spring 11 deforms due to the force and separates from the insertion hole 15 as the spring pin 8 slides, thereby canceling the fixation.

[0036] Figures 2-9 As shown, a step 12 is provided on the inner wall of the sleeve 14. The spring 11 is sleeved on the spring pin 8 and its two ends are respectively abutted on the second end of the spring pin 8 and the step 12. This design serves to limit the position of the spring 11 and prevent the spring 11 from sliding inside the sleeve 14.

[0037] Figures 2-9 As shown, an adjusting knob 9 is provided on the first end of the spring pin 8. The adjusting knob 9 rests against the sleeve 14. Pulling the adjusting knob 9 can cause the spring pin 8 to retract into the sleeve 14. Therefore, during the sliding process of the spring pin 8, the adjusting knob 9 restricts the sliding range of the spring pin 8, preventing the spring pin 8 from entering the sleeve 14. In addition, the adjusting knob 9 can easily drive the spring pin 8 to slide, improving the ease of operation. The spring pin 8 and the adjusting knob 9 are threadedly connected. This design facilitates the installation of the spring pin 8 and allows the insertion depth of the spring pin 8 to be controlled by rotating the adjusting knob 9.

[0038] Figures 2-9 As shown, the second end of the spring pin 8 is provided with a guide arc surface, which facilitates the insertion of the spring pin 8 into the socket 15.

[0039] The folding structure of the electric scooter upright provided by this utility model has been described above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
