[0002] In the field of modern transportation, a single vehicle in a single environment cannot meet the needs of complex scenarios. Traditional aircraft, such as fixed-wing aircraft and helicopters, can achieve efficient air travel, but they require strict landing sites and have little access to land and water environments. Once they leave the airport and other dedicated facilities, they cannot move flexibly. Land vehicles, such as cars and off-road vehicles, can adapt to most landforms, but they are limited by water and air obstacles and cannot cross natural barriers such as rivers and lakes. They also cannot achieve rapid air transfer. Water vehicles, such as ships and speedboats, can only operate in water and lose all access to land. They also need to rely on other transportation tools for assistance during water transfer, which is inefficient.

[0003] Although some amphibious vehicles have appeared in some fields, such as amphibious vehicles, their functions still have significant limitations. Most amphibious vehicles can only switch between land and water and lack air travel capabilities. Their speed, stability on land, and maneuverability on water are far inferior to those of professional single-vehicle vehicles.

[0004] With the increasing demand for multi-environment transportation tools in emergency rescue, field exploration, and cross-domain logistics, the development of a vehicle that can seamlessly switch between air, land, and water and maintain good performance in each scenario has become a focus in the industry. The functional fragmentation and scenario limitations of traditional vehicles have driven the development of new vehicles with multi-scenario adaptability.

[0023] Further, the wing 4 has a retractable structure.
