[0002] With the diversification of urban travel modes, electric scooters have gradually become the preferred tool for short-distance travel for urban residents due to their portability, flexibility and environmental friendliness. In the design of electric scooters, the rear wheel bracket is an important component that carries the rear wheel and connects the main body of the scooter. Its structural design and performance directly affect the stability, safety and comfort of the entire vehicle.

[0003] As shown in the disclosure / announcement number CN209535337U, the rear wheels of most scooters currently are directly connected to the tail of the pedal, which does not have a good shock-absorbing effect. When a shock-absorbing mechanism needs to be installed, it is necessary to match a single set of rear wheel brackets to achieve this, such as shown in the disclosure / announcement number CN215155345U. The above-mentioned shock-absorbing mechanism is a horizontal type, and the rear end of this shock-absorbing mechanism is sleeved on the shaft of the rear wheel bracket. When in use, the lack of a limit may cause movement, which may pose a hidden danger to the structural safety of the scooter. For a longitudinally arranged shock-absorbing mechanism, in order to adapt to this shock-absorbing mechanism, it is often necessary to design and produce a new set of rear wheel brackets, which undoubtedly increases the manufacturing cost and complexity.
