Description

Aerocar with shared wheel-wing power Technical Field The invention relates to the technical field of aero-automobiles and electric driving, in particular to an aero-automobile with shared wheel-wing power, and especially relates to an aero-automobile structure scheme for realizing the power sharing of an aero-rotor system and a ground tire system by utilizing an axial double-rotor motor and realizing the switching of two working conditions of land and air by folding a horn and fusing a vehicle body. Background With the development of low-altitude economy, a flying car with both ground traveling capability and air flying capability gradually becomes an important development direction in the field of intelligent transportation. The vehicles generally need to realize the switching between the land mode and the flight mode under different working conditions so as to respectively meet the requirements of road traffic efficiency and air maneuvering performance. However, due to the significant differences in the power output form, the load characteristics, the structural layout and the like of the two working modes, the aerocar faces higher technical challenges in the aspects of power system integration, structural design and the like. In structural design, the existing aerocar mostly adopts independent power systems respectively used for ground running and air flying so as to respectively drive wheels and rotors to work. The scheme is direct in function realization, but a plurality of sets of motors and matched transmission mechanisms thereof are generally required to be configured, so that the whole vehicle is complex in structure and low in system integration level, the weight and the volume of the whole vehicle are obviously increased, and the lightweight design and the energy efficiency improvement of the aerocar in a flight mode are not facilitated. Meanwhile, the coordination control difficulty among the multiple power systems is high, and the reliability and the maintenance convenience of the whole vehicle are limited to a certain extent. When the aerocar is in the land mode, the energy consumption level, the running resistance and the overall dimension of the aerocar have important influences on the economy and the practicability of the whole car. However, in the prior art, the rotor wing and the horn thereof are mostly arranged in an externally hung or simple folding mode under the ground running state, so that the rotor wing system is difficult to realize compact fusion with the vehicle body structure, not only occupies a large external space, but also easily increases running wind resistance, and affects the aerodynamic performance and the overall shape consistency of the vehicle. In urban roads, narrow spaces or complex environments, the externally hung or exposed structures also have a certain collision risk, and the safety and the adaptability of the vehicle are affected. Therefore, the existing aerocar still has obvious defects in the aspects of power system integration mode, horn structure design and integrated fusion of the horn and the car body, and needs to be further improved.

In addition, the axial double-rotor motor is utilized to realize the power sharing of the rotor system and the wheel running system, so that the number of power systems is reduced, and the structural complexity and weight of the whole vehicle are reduced.
