DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figs. 1-7 In the embodiments of the utility model, a scooter lap joint structure comprises a front frame assembly 1 and a rear frame assembly 2, the rear frame assembly is provided with rear connecting plates 21 on both sides of the front end, the rear connecting plates 21 are provided with rear hooks 22 on the front end, the rear connecting plates 21 are provided with rear hanging pins 23 on the side surface, the front frame assembly 1 is provided with mounting plates 11 on both sides of the rear end, the mounting plates 11 are provided with front connecting plates 12 on the rear end, the front connecting plates 12 are provided with front hooks 13 on the rear end, the front hooks 13 are hanged and matched with the rear hanging pins 23, the front connecting plates 12 are provided with front hanging pins 14 on the side surface, the front hanging pins 14 are hanged and matched with the rear hooks 22, the rear end of the mounting plate 11 is further provided with an anti-off assembly 15, and the anti-off assembly 15 is used for limiting the rear hanging pin 23 to prevent the rear hanging pin 23 from being separated from the front hook 13.

[0023] Before the lap, make sure the anti-off component 15 is in the open state, then lift the rear half of the front frame assembly 1, hook the two front hanging pins 14 on both sides of the rear end of the front frame assembly 1 on the two rear hooks 22 on both sides of the front end of the rear frame assembly 2, and hook the two rear hanging pins 23 on both sides of the front end of the rear frame assembly 2 on the two front hooks 13 on both sides of the rear end of the front frame assembly 1, and finally make the anti-off component 15 in the locking state, limit the rear hanging pin 23 to prevent the rear hanging pin 23 from being separated from the front hook 13, that is, the lap of the scooter is completed. When the front frame assembly 1 and the rear frame assembly are to be separated, the anti-off component 15 releases the limitation of the rear hanging pin 23, and then the rear half of the front frame assembly 1 is lifted to make the front hook 13 separate from the rear hanging pin 23 and the rear hook 22 separate from the rear hanging pin 23. The front frame assembly 1 and the rear frame assembly can be separated. In this way, without the help of tools, the lap and disassembly can be completed quickly and conveniently, and has the characteristics of stable and reliable lap and simple operation.

[0024] The anti-off component 15 includes a lock frame 151, a first rotating shaft 152, a torsional spring 153, and an anti-off lock piece 154. The lock frame 151 is composed of a top plate and two side plates. The anti-off lock piece 154 is rotatably installed between the two side plates of the lock frame 151 through the first rotating shaft 152. The bottom of each of the two side plates of the lock frame 151 is provided with a first clamping hole 155. The rear end of the anti-off lock piece 154 is provided with a second clamping hole 156. The torsional spring 153 is sleeved on the first rotating shaft 152. Under the action of the torsional spring 153, the rear end of the anti-off lock piece 154 has a tendency to move away from the first clamping hole 155. It can be understood that under the action of the torsional spring 153, the rear end of the anti-off lock piece 154 moves away from the first clamping hole 155, which facilitates the hooking of the rear hanging pin 23 on the front hook 13. After lifting the rear half of the front frame assembly 1 to hook the rear hanging pin 23 on the front hook 13, the rear half of the front frame assembly 1 is lowered, the rear hanging pin 23 is clamped in the first clamping hole 155, and the anti-off lock piece 154 is pushed to the locking position. At this time, the first clamping hole 155 cooperates with the second clamping hole 156 to clamp the rear hanging pin 23.

[0025] The anti-off component 15 further includes a lock tooth 157 and a second rotating shaft 158. The lock tooth 157 is rotatably installed between the two side plates through the second rotating shaft 158. The rear end of the lock tooth 157 is provided with an abutting portion 159. The front end of the anti-off lock piece 154 is provided with an abutting groove 1510. The torsional spring 153 has two spring bodies. One of the spring bodies of the torsional spring 153 is sleeved on the first rotating shaft 152, and the other spring body of the torsional spring 153 is sleeved on the second rotating shaft 158. Under the action of the torsional spring 153, the rear end of the lock tooth 157 has a tendency to move close to the abutting groove 1510. After the first clamping hole 155 cooperates with the second clamping hole 156 to clamp the rear hanging pin 23, under the action of the torsional spring 153, the rear end of the lock tooth 157 rotates upward, so that the abutting portion 159 abuts against the inner wall of the abutting groove 1510, thereby preventing the anti-off lock piece 154 from rotating again.

[0026] The anti-falling assembly 15 further comprises a handle support frame 1511, a handle 1512, a reset spring 1513, a pull cable 1519, a mounting rod 1514 and a lifting plate 1515. The top of the front frame assembly 1 is provided with a seat frame 16. The handle support frame 1511 is mounted on the seat frame 16. The mounting rod 1514 is arranged through the handle support frame 1511. The lifting plate 1515 is arranged at the upper end of the mounting rod 1514. The handle 1512 is arranged at the lower end of the mounting rod 1514. The reset spring 1513 is sleeved on the mounting rod 1514. One end of the reset spring 1513 is connected with the lifting plate 1515. The other end of the reset spring 1513 is connected with the handle support frame 1511. Under the action of the spring, the lifting plate 1515 has a downward moving tendency. The initial end of the pull cable 1519 is connected with the lifting plate 1515. The terminal end of the pull cable 1519 is connected with the front end of the lock tooth 157. When it is needed to separate the front frame assembly 1 from the rear frame assembly 2, the rear half of the front frame assembly 1 is lifted by pulling the seat frame 16. When the seat frame 16 is pulled, the handle 1512 is pressed at the same time, so that the lifting plate 1515 moves upward. The rear end of the lock tooth 157 is pulled by the pull cable 1519 to rotate downward, so that the abutting portion 159 is separated from the abutting groove 1510, the limiting effect on the anti-falling lock piece 154 is lost, the tail of the front frame assembly 1 is continuously lifted, until the rear hanging pin 23 is separated from the anti-falling lock piece 154 and the front hook 13, and the front hanging pin 14 is separated from the rear hook 22, so that the front frame assembly 1 can be separated from the rear frame assembly 2.

[0027] In order to better protect the pull cable 1519 and prolong the service life, the top plate of the lock frame 151 is provided with a connecting frame 1516. The connecting frame 1516 is connected with the handle support frame 1511 and is connected with a cable sleeve 1517. The handle support frame 1511 is rotatably mounted with a roller 1518 on both sides of the mounting rod 1514. The terminal end of the pull cable 1519 passes through the roller 1518 and the cable sleeve 1517 and is connected with the front end of the lock tooth 157.

[0028] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
