[0012] The present design is described in detail below using the examples and drawings.

[0013] As from Fig. 1 to Fig.As can be seen in Figure 3, the convenient folding mechanism according to the invention for electric scooters consists of a folding assembly 2 between the handlebar 1 and the front fork 3, wherein the folding assembly 2 has a joint A6 and a joint B7, wherein the joint A6 is connected to an upper end of the joint B7 via a pivot pin 8 and can rotate about the pivot pin 8 as its axis center relative to the joint B7, wherein a locking groove (A13, B14) is formed on the front side of both the joint A6 and the joint B7, wherein the front side of the joint A6 is connected to a locking buckle 4 that is pivotable about the joint B7, which comprises a worm gear 10, the front end of which is coupled to a C-shaped clamp 5 that is rotatable about the worm gear 10 as its axis center, wherein the C-shaped clamp 5 can pivot about the joint B7 so that the joint A6 can be separated from the joint B7 disconnects or couples to it.

[0014] It can preferably be provided that the upper end on the front side of the joint B7 is formed with a stop-round groove 11, the rear end of which is formed with a threaded hole 16, wherein the diameter of the threaded hole 16 is smaller than the diameter of the stop-round groove 11.

[0015] It can preferably be provided that the worm 10 is provided with a locking nut 12, at the front end of which a projection ring 15 is attached, wherein the projection ring 15 limits the connection position of the C-shaped clamp 5 to the locking buckle 4 in order to prevent possible detachment of the C-shaped clamp 5 from the locking buckle 4, wherein the diameter of the projection ring 15 is larger than the locking nut 12 and the locking nut 12 can connect to the threaded hole 16 in the joint B7 and pivot within the threaded hole 16, while the projection ring 15 can simultaneously engage or disengage from the stop groove 11 with the pivoting of the locking nut 12 within the threaded hole 16.

[0016] It can preferably be provided that a plug-in insert 9 is attached behind each of the upper and lower ends of the C-shaped clamp 5, which can be inserted into the locking grooves A13 and B14 by pivoting the locking buckle 4 about the hinge B7 and then engages with the locking grooves A13 and B14. The plug-in insert 9 separates from the locking grooves A13 and B14 when the locking buckle 4 pivots about the hinge B7.

[0017] It can preferably be provided that the joint A6 is connected to the handlebar 1 with its upper end, and the joint B7 is connected to the front fork 3 with its lower end.

[0018] It is therefore understandable that the convenient folding mechanism according to the invention consists of a folding assembly 2 between the handlebar 1 and the front fork 3, wherein the folding assembly 2 has a pivot joint A6 and a pivot joint B7, wherein the pivot joint A6 is connected to an upper end of the pivot joint B7 via a pivot pin 8 and can rotate about the pivot pin 8 as its axis center relative to the pivot joint B7, wherein a locking groove (A13, B14) is formed on the front side of both the pivot joint A6 and the joint B7, wherein the front side of the joint A6 is connected to a locking buckle 4 that is pivotable about the joint B7 and which comprises a worm gear 10, the front end of which is coupled to a C-shaped clamp 5 that is rotatable about the worm gear 10 as its axis center. A plug insert 9 is attached behind each of the upper and lower ends of the C-shaped clamp 5. For practical use, the locking buckle 4 can be turned to lock the front sides of the joints A6, B7 or the folding set 2.The insert 9 of the C-shaped clamp 5 will, with the movement of the locking buckle 4, engage in the locking grooves A13 and B14 and then align with them. Conversely, if the locking buckle 4 is rotated in the opposite direction, it will move the C-shaped clamp 5 along with it, causing the insert 9 of the C-shaped clamp 5 to detach from the locking grooves A13 and B14. This separates the front faces of joint A6 and joint B7, allowing joint A6 to rotate around joint B7 and thus achieving the desired folding action.
