[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] like Figures 1 to 6 As shown, this embodiment provides a scooter folding device locking structure, which includes: a stand pipe 1, an upper folding seat 2, a lower folding seat 3, a locking tongue 5, a hook 6, a first fixed shaft 7, a cam 8 and a wrench 9. The upper folding seat 2 is connected to the bottom end of the stand pipe 1, and the outer side wall of the lower folding seat 3 is convexly provided with a first mounting ear and a second mounting ear 4. The first mounting ear and the second mounting ear 4 are opposite and spaced apart. The upper folding seat 2 is rotatably connected to the second mounting ear 4 through a rotating shaft 16, the locking tongue 5 is connected to the upper folding seat 2, and the hook 6 is rotatably connected to the first mounting ear. A protrusion is provided on the top of the hook 6, and the locking tongue 5 is provided with a card slot. The protrusion is engaged with the card slot. The bottom of the hook 6 is concavely provided with an abutting arc surface 61. The cam 8 is fixedly sleeved on the first fixed shaft 7, and the first fixed shaft 7 is rotatably connected to the first mounting ear. The cam 8 can apply a force to the abutting arc surface 61 to make the protrusion move upward and disengage from the card slot. The wrench 9 is fixedly connected to the first fixed shaft 7, and the hook 6 is placed inside the wrench 9. Furthermore, the connection point between the first fixed shaft 7 and the first mounting ear is arranged below the connection point between the hook 6 and the first mounting ear. With this arrangement, when folding is required, the first fixed shaft 7 can be driven to rotate outward by pulling the wrench 9. Under the limit of the hook 6, the cam 8 exerts a force on the abutting arc surface 61 to push the protrusion upward and disengage from the slot to achieve unlocking. The wrench 9 is further pulled and rotated outward to a set angle. The wrench 9 interferes with the abutting arc surface 61, and the hook 6 is pushed away from the lock tongue 5 to achieve full opening. This ensures the convenience of unlocking and folding the upper folding seat 2 and the lower folding seat 3. At the same time, the interference friction between the cam 8 and the abutting arc surface 61 is large, and the stability is good, so that the hook 6 is not easily deflected during the unlocking and opening process.

[0043] Optionally, in order to improve the connection stability of the hook 6, the scooter folder locking structure further comprises a first elastic member 10 and a second fixed shaft 11, the second fixed shaft 11 is fixedly connected to the hook 6, and the second fixed shaft 11 is rotatably connected to the first mounting lug, the first elastic member 10 is configured to drive the second fixed shaft 11 to always have a tendency to rotate towards the direction close to the lower folding seat 3. Specifically, the first elastic member 10 is a torsion spring.

[0044] Further, the first mounting lug comprises two opposite and spaced side lugs 12, the two ends of the second fixed shaft 11 are rotatably connected to the two side lugs 12 respectively, and the two ends of the first fixed shaft 7 are rotatably connected to the two side lugs 12 respectively. In this way, the connection points of the first fixed shaft 7 and the second fixed shaft 11 are added, and the reliability of the rotatable connection is improved.

[0045] Optionally, the scooter folder locking structure further comprises a sliding member 13 and a locking block 14, the locking block 14 is connected to the upper folding seat 2, the inside of the wrench 9 is provided with a sliding groove extending in the vertical direction, the sliding member 13 is in sliding fit with the sliding groove, and the locking block 14 can abut against the sliding member 13 to limit the movement of the sliding member 13 away from the upper folding seat 2. In this way, the wrench 9 can be locked to ensure the stability of the position of the wrench 9 and improve the safety.

[0046] Optionally, the sliding member 13 comprises an inner sliding block 131, an outer sliding block 132 and a second elastic member 15, the inner sliding block 131 is closer to the upper folding seat 2 than the outer sliding block 132, the outer sliding block 132 comprises a connecting part and a first gripping part connected in sequence, the connecting part is connected to the inner sliding block 131, the first gripping part protrudes from the wrench 9, the locking block 14 abuts against the inner sliding block 131, and the second elastic member 15 is configured to give the inner sliding block 131 an acting force to limit the inner sliding block 131 from disengaging from the locking block 14. Further, the second elastic member 15 is a compression spring, and the two ends of the second elastic member 15 abut against the upper end face of the inner sliding block 131 and the inner wall of the wrench 9 respectively. In this way, the first gripping part can be manually pulled upward to drive the inner sliding block 131 to slide upward against the acting force of the second elastic member 15, so that the inner sliding block 131 disengages from the locking block 14, thereby realizing the unlocking of the wrench 9.

[0047] Specifically, the following scheme is exemplarily given in the embodiment: the bottom end of the inner sliding block 131 protrudes a first protruding part, the top end of the locking block 14 protrudes a second protruding part, the first protruding part is located between the second protruding part and the upper folding seat 2, and the second protruding part can abut against the first protruding part to limit the first protruding part from rotating away from the upper folding seat 2.

[0048] Optionally, in order to improve the connection stability and reliability of the first fixed shaft 7, the bottom end of the wrench 9 is provided with a first connecting lug and a second connecting lug, the first connecting lug and the second connecting lug are oppositely and spacedly arranged, and the first connecting lug and the second connecting lug are both fixedly sleeved on the first fixed shaft 7.

[0049] Optionally, in order to facilitate manual turning of the wrench 9, the top end of the wrench 9 is provided with a second gripping portion, and the second gripping portion is obliquely upward arranged away from the upper folding seat 2.
