Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a rear shock absorption structure for scooters with replaceable springs and adjustable damping. Background Technology

[0002] Scooters are easy to carry due to their lightweight and compact size, making them a popular mode of transportation for sports and leisure. However, when a scooter encounters uneven surfaces, the pedals can become unstable due to the up-and-down movement of the front and rear wheels, and the user's foot may slip off the pedals due to excessive bouncing of the rear wheel.

[0003] Therefore, some scooters have attempted to incorporate shock absorption devices between the pedals and the rear wheel to prevent excessive rear wheel bounce and improve handling. However, different road conditions and usage scenarios require different rear wheel shock absorption structures with varying spring tensions. Existing rear wheel shock absorption structures do not address these issues and do not facilitate adjusting the spring tension or replacing the spring. Utility Model Content

[0040] As described above, the above-mentioned settings reduce the frictional resistance between the pull rod and the limiting through hole.
