Description

Technical Field

[0001] The utility model relates to a chassis of a mobility scooter, in particular to a double-layer shock-absorbing chassis of an electric mobility scooter. Background Art

[0002] With the diversification of urban travel modes, electric scooters have gradually become an important choice for people's daily travel due to their convenience and environmental protection. However, with the rapid development of the market, the shock absorption performance problems of electric scooters have gradually been exposed, becoming a bottleneck restricting their further development.

[0003] Most of the popular electric scooters on the market use traditional shock-absorbing designs, which have poor shock-absorbing effects. During driving, the vibration caused by uneven road surfaces will be directly transmitted to the passengers, greatly reducing the riding experience. Long-term riding on such electric scooters will not only make people feel tired and uncomfortable, but may also cause potential damage to the spine and joints.

[0004] In addition to the impact on passengers, poor shock absorption of electric scooters can also have a negative impact on driving stability. During driving, the shaking caused by vibration will not only reduce riding comfort, but may also affect the driver's control stability and increase the risk of traffic accidents. Especially when driving at high speeds or emergency braking, electric scooters with poor shock absorption performance are more likely to shake, further increasing safety hazards.

[0011] A connecting hole is provided in the center of the guide seat, and the top of the connecting hole is connected to the upper end of the shock absorber, so that the first layer of shock absorption is achieved through the shock absorber;

[0012] A spring is sleeved on the guide groove, and the other end of the spring is placed at the bottom of the spring seat, so that the spring plays a second layer of shock absorption effect.

[0013] As a preferred technical solution, the limiting structure includes a limiting groove and a limiting column arranged on the side of the guide groove;

[0014] The limiting column is inserted into the side of the panel and placed in the limiting groove of the chassis body, thereby limiting the activity of the panel; the limiting column and the panel are positioned by a positioning structure to facilitate the installation and removal of the limiting column.

[0015] As a preferred technical solution, the positioning structure includes a spring groove and a positioning ball which are arranged on the limiting column;
