It is very convenient to use and can meet people's daily transportation needs for most short-distance travel. It is deeply loved by people.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: due to volume limitations, the rear wheel shock-absorbing structure of most scooters is single, and it is difficult to replace the spring to adjust the shock-absorbing damping. If the spring is deformed under stress for a long time, the shock-absorbing performance will decrease, and the road will be very bumpy when passing through potholes, especially when two sets of rear wheels use the same drive shaft, which will greatly reduce the comfort of the personnel. Utility Model Content

[0004] In order to improve the problem that due to volume limitation, most scooters have a single rear wheel shock-absorbing structure, and it is difficult to replace the spring to adjust the shock damping. If the spring is deformed under force for a long time, the shock absorption performance will be reduced, and it will be very bumpy when passing through potholes. In particular, two sets of rear wheels using the same drive shaft will greatly reduce the comfort of the personnel. The present application provides a scooter rear wheel shock-absorbing structure.

[0006] It is further provided that the top ends of the four groups of connecting rings are all fixedly connected to a first telescopic rod, and the first telescopic rod is semicircular and is provided in four groups.

[0007] It is further configured that the bottom ends of the two groups of the first telescopic columns are both provided with telescopic sleeves, and the outer walls of the top ends of the four groups of the first telescopic rods are respectively threadedly connected to the inner walls of the bottom ends of the two groups of telescopic sleeves.

[0008] It is further configured that two groups of springs are respectively sleeved on the two groups of the first telescopic columns and the four groups of the first telescopic rods, and spring shock absorbers are provided on the tops of the two groups of the first telescopic columns.

[0009] It is further arranged that the top ends of the two groups of the first telescopic columns are rotatably connected to a rotating seat via a rotating shaft, and the two groups of the rotating seats are rotatably connected to the rear ends of the second telescopic rods.

[0010] It is further provided that a sliding groove is opened at the rear end of the limiting column, a threaded rod is arranged in the sliding groove, the left end of the threaded rod is fixedly connected to the adjustment handle, and the right end of the threaded rod is connected to the sliding groove through a bearing.
