[0002] With the diversification of modern transportation and the growing demand for convenient and environmentally friendly travel, scooters, as a light and flexible means of transportation, have received widespread attention and popularity. Although traditional two-wheeled scooters have certain advantages in portability and speed, they are less stable and pose certain safety risks for beginners and children. In order to improve the stability and safety of scooters while maintaining their lightness and flexibility, three-wheeled scooters came into being. By adding a wheel at the front or rear, three-wheeled scooters effectively improve the stability of the body, making it easier for riders to maintain balance and reducing the risk of falling. However, existing three-wheeled scooters still have certain defects in design. Existing three-wheeled scooters have poor shock absorption effects, lack flexibility in adjusting the front wheel angle, cannot adapt to the needs of different riders and riding environments, and are dangerous for beginners and children.
