The telescopic wing is an important part of the flying car, so as to realize the air-land amphibious conversion of the flying car. For the increasingly serious traffic congestion problem, flying cars have become an important solution to solve such problems in the future, and flying cars that can solve such problems must ensure that the wings can be retracted, and the wings can be as stealthy as possible when the car is driving. It can run in parallel with traditional cars when it hinders the traveling of the same vehicle; on the other hand, it can realize the extension of the wings in the state of the car, and realize the flight mode after a certain period of time.

In order to pursue sufficient low-altitude flight power, most of the existing flying car test samples adopt the self-rotor or multi-rotor type. However, most of these designs face the following disadvantages:

(1) The wing is difficult to fold. In order to provide sufficient power, the rotor is often required to be larger in size; most of the existing designs directly fix the rotor on the roof, and the rotor blades cannot be retracted into the car, similar to the structure of a helicopter.

(2) The entire vehicle occupies too much space. Most flying cars use the fuselage of the aircraft as the frame to cater for the folding wings, resulting in the fuselage being too large, making it impossible to run parallel to the vehicle; how to design a car The body, especially the telescopic wing based on the car body, becomes a problem.
