[0039] Specifically, the upper end of the positioning baffle 7 is symmetrically protruded to form a positioning head 701 for fixing the elastic member 8, and the lower end is protruded to form a positioning block 702, which is used to be clamped at the bottom of the slide groove 504 of the connecting piece 502 or in the second positioning notch group 405. In the above design, the positioning head 701 works together with the limiting connector 903 to improve the connection and working stability of the elastic member 8. The design of the positioning block 702 can improve the stability of the positioning baffle 7 when it is unfolded and folded, especially in the folded state, it plays a locking role between the positioning baffle 7 and the ball head 4, prevents the folded state from being damaged by unexpected external forces, and improves the stability and safety of the folding bicycle.

[0040] Specifically, the lock assembly includes an upper clamp 22 and an upper lock handle 23, the upper clamp 22 is clamped on the outer side of the upper end of the vertical pipe 3, and the upper lock handle 23 is connected to the upper clamp 22 by riveting nuts and screws, and the handlebar T-bar assembly includes a vertical bar 24 and a handlebar 25, one end of the vertical bar 24 is inserted into the vertical pipe 3 and connected and fixed by the lock assembly, and the other end is fixed to the handlebar 25, and the two ends of the handlebar 25 are provided with handle sleeves 26. With the above design, the lock assembly has a simple structure and is easy to operate, and can quickly complete the assembly and disassembly between the vertical pipe 3 and the vertical bar 24, and adjust the height of the handlebar T-bar assembly.

[0041] Specifically, an upper fixing sleeve 27 and a lower fixing sleeve 28 are also sleeved on the vertical rod 24, the upper end of the upper fixing sleeve 27 is clamped at the upper end of the vertical tube 3, and the lower fixing sleeve 28 is connected to the vertical rod 24 through an anchor. In the above design, the upper and lower fixing sleeves can be plastic sleeves, the upper fixing sleeve 27 can avoid scratches during telescopic adjustment (the contact wear between the handlebar T-bar assembly and the inner wall of the vertical tube 3 during telescopic adjustment), and the lower fixing sleeve 28 can strengthen the rigidity of the vertical rod 24, reduce shaking, and thus improve the stability of the scooter.

[0042] Specifically, a groove is provided on one side of the vertical rod 24, a marble 29 is elastically designed in the groove, and adjustment holes 301 for the marble 29 to pass through are provided at intervals on the vertical pipe 3. A countersunk screw is connected to the upper beam clamp 22, and the countersunk screw passes through the upper beam clamp 22, the vertical pipe 3 and the upper fixing sleeve 27 in sequence, and the end of the countersunk screw contacts or stays away from the groove, and the anchor is connected to the groove of the vertical rod 24. The above design facilitates the disassembly and adjustment between the accessories.

[0043] Specifically, the front and rear of the chassis can be provided with decorative covers 30, whose edges are round and go around a circle; the front suspension 11 is a variation of a circular structure, that is, it is large in the middle and gradually becomes smaller at both ends. The above design can make the overall appearance of the scooter more concise and beautiful.

[0044] Specifically, the rear wheel assembly includes a rear wheel 31, a brake assembly and other conventional structures on existing scooters.

[0045] The scooter of the present invention has a simple structure. Through the design of the ball head folding component, it is only necessary to operate the pull sleeve 6 to drive the pull sleeve 6 to move the positioning baffle 7 upward until the positioning baffle 7 is disengaged from the slot 403 on the fixed head 401. At this time, the folding piece 5 can be rotated along the ball head 4 to fold the accessories such as the riser 3 toward the base frame 1. When the positioning baffle 7 is folded to face the second positioning notch group 405, due to the action of the elastic member 8, the positioning baffle 7 will be stuck in the second positioning notch group 405 for folding and fixing. Conversely, when it needs to be unfolded, it is only necessary to pull the pull sleeve 6. The operation is convenient, and the accessories for cooperating with the work are also relatively streamlined, which can improve the stability of the operation, thereby improving the convenience of operation and the stability of folding and storage of the scooter.

[0046] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
