Description

Aerocar wing and rotor wing hybrid type retraction system and aerocar The application discloses a split application of China patent application of a wing and rotor hybrid type retraction system of an aerocar and an aerocar, which is filed by China patent office at 22 months of 2022 and has the application number 202210874278.6. Technical Field The invention relates to the technical field of aircraft and automobile design, in particular to a wing and rotor wing hybrid retraction system of an aerocar and the aerocar. Background At present, urban congestion has become a worldwide problem. On one hand, ground automobiles are continuously increased, urban traffic pressure is increasingly increased, traffic jams frequently occur, and on the other hand, ground space is limited, people, automobiles and the ground are difficult to balance, so that the demands of people on the air traffic are more and more strong. The concept of flying car and the technology of patent published by the prior publication are mainly focused on the following three aspects. Firstly, the flying car based on the multi-rotor layout and capable of taking off and landing vertically has the advantages of small occupied area, capability of taking off and landing at any time and short endurance time and mileage. Secondly, the aerocar based on the fixed wing layout has the advantages of long endurance and large load, and has the defect of taking off and landing after running on a runway. Thirdly, the aerocar based on the tilting rotor or tilting wing technology has the advantages of integrating the advantages of the multi-rotor and fixed wing layout and the disadvantages of larger wing volume. In order to solve the above-mentioned problems, for example, patent application No. 201820928031.7 discloses a six-rotor arrangement structure of a tandem wing aerocar and the aerocar, which comprises two front rotors, two rear rotors, a tail rotor and a head rotor, wherein the two front rotors and the two rear rotors are symmetrically arranged at the left side and the right side of the car sequentially through the corresponding front rotors and the rear rotors, the tail rotor is arranged at the rear part of the car through a lower tail rod, the head rotor is arranged at the front part of the car through a head connecting rod, the six rotors are cooperatively matched to provide upward flying power for the aerocar, and the power generated by the rotors maintains the vertical direction of the flying, and the power generated by the rotors is offset with the gravity of the car, so that the car can maintain balance in the air. The patent application with the application number 201820928120.1 discloses a single-wing four-rotor structure on an aerocar and the aerocar, which comprises two side rotors, a tail rotor and a head rotor, wherein the left side and the right side of a main body of the aerocar are symmetrically provided with wings which extend horizontally outwards, the side rotors are arranged below the middle part of the wings, the tail of the main body of the aerocar is provided with a lower tail rod which extends horizontally backwards, the tail rotor is arranged below the lower tail rod, the head of the main body of the aerocar is provided with a head connecting rod which extends horizontally forwards, the head rotor is arranged below the head connecting rod, and the head rotor is arranged on the periphery of the main body of the aerocar through the arrangement of the four rotors, so that the aerocar can take off. The patent application with the application number of 201820928117.X discloses a tandem double-wing folding and unfolding system of an aerocar and the aerocar, which comprises two front wings and two rear wings which are symmetrically arranged on two sides of a main body of the aerocar, wherein a front rotor wing is arranged at the position, close to the tail end, of each front wing, and a rear rotor wing is arranged at the position, close to the tail end, of each rear wing. The front wing and the rear wing are opened when the flying automobile flies, the front rotor wing and the rear rotor wing provide the flying lift force, and the front wing and the rear wing are rotated to be retracted into the automobile body when the land surface runs, so that the automobile is attractive. The high number of wings in these three patents results in a relatively complex structure; the number of the rotor wings is small, the requirement of stable lifting cannot be met, the requirement of occupying a small space and being in a fixed state can be met when the wing wings of the rotor wings are in an automobile state structure, the technical scheme is not involved, and in a word, the three patent technical schemes are not simple in structure, and the lifting performance cannot be easily controlled stably. Therefore, how to provide a space-saving, simple and stable take-off and landing, and stable flying car is a problem that needs to be solved by those skilled
