Background technique

With the popularization of electric vehicles, the problem of inconvenient charging of electric vehicles has become increasingly prominent; currently, users who buy electric vehicles are generally limited to commuting in the city, and users who need to go out for a long time still prefer to use fuel vehicles. Even for short-distance driving in the city, users need to pay attention to the remaining power of the electric vehicle, otherwise it is easy to break down without electricity halfway. The scheme of setting up charging equipment on the roadside similar to two-wheeled battery vehicles is not very suitable for electric vehicles. On the one hand, the footprint of electric vehicles is much larger than that of two-wheeled battery vehicles, and fixed-point parking and charging may cause traffic congestion. On the other hand, electric vehicles consume much more power than two-wheeled battery vehicles. In the absence of significant breakthroughs in battery charging technology, it takes a long time to stop and charge halfway.

Compared with the prior art, the beneficial effects of the present invention are: the present invention uses the guide rail car running on the power transmission guide rail and maintaining the same driving speed as the electric vehicle, and cooperates with the electric vehicle to be electrically connected to the guide rail car through the electrical connection of the aircraft and the guide rail car. Charging the electric vehicle in motion realizes the function of charging the electric vehicle without stopping, and the aircraft can be separated from the guide rail car at any time when the electric vehicle is fully charged or under other circumstances, which will not restrict the free driving of the electric vehicle .

When the aircraft is not working, the aircraft is sucked tightly on the upper end of the box cover of the top winding assembly of the electric vehicle through the second electromagnet (the iron core). The oriented magnetic field decouples the aircraft from the electric vehicle.

When the electric vehicle needs to be charged, the control system of the electric vehicle sends a signal to the server of the charging system, and the server controls the nearby guide rail car to keep running at the same speed as the electric vehicle, and then the control system of the electric vehicle sends a signal to the aircraft to make the aircraft fly to the corresponding The guide rail car and stop at the lower end of the guide rail car, so that the electric vehicle and the power transmission guide rail form an electrical connection; during the flight of the aircraft, the control system simultaneously controls the rotation of the winding motor of the winding assembly to release the wire from the winding reel; the electric vehicle charging After the completion, the aircraft flies back to the top of the electric vehicle, and at the same time the winding motor rotates in reverse to make the wire wind back on the winding reel.

The aircraft provides driving force through the upper driving fan in the fan installation part, and part of the airflow generated by the upper driving fan is blown downward from the air outlet slits of each air outlet ring, and the air outlet speed of each air outlet ring is adjusted in combination with the adjustment assembly. In this way, the horizontal flight or turning of the aircraft can be realized. Since the air outlet rings located on the outer periphery of the aircraft only play the role of adjusting the attitude of the aircraft, without fans providing power, it is not easy to cause the aircraft to lose control or Harmful to people or animals, good safety. The appearance of the aircraft is similar to that of a four-axis aircraft, and the four air outlet rings only function to adjust the attitude, so the present invention should be a single-axis aircraft in essence.

Further, according to the Coanda principle, the airflow ejected from the air outlet slit of the air outlet ring will flow along the deflector wall to form a conical wind film, and the conical wind film will drive the The air flows downward together, so that when the part of the air outlet slit is blocked during the flight of the aircraft, the overall airflow formed by the air outlet slit has little influence, which is beneficial to the stability of the flight attitude of the aircraft.

Further, the axial direction of the wind ring is perpendicular to the radial direction of the fan installation part, and an angle of 5-20 degrees is formed between the axial direction of the air outlet ring and the horizontal direction, and the air outlet slot of the air outlet ring blows out The horizontal wind force generated by the wind is opposite to the direction of rotation of the fan blades driving the fan. Through such a design, the wind blown out of the air outlet slit of the air outlet ring can counteract the reaction force generated when the upper drive fan, or the upper drive fan and the lower drive fan rotate; The wind speed can realize the overall forward or reverse rotation of the aircraft. By adjusting one or two adjustment components to make the air outlet speed of one or two air outlet rings, the entire aircraft can be in a tilted state, so that the aircraft can be driven to fly in a horizontal direction.

The landing gear is retracted or unfolded correspondingly with the take-off and landing of the aircraft. When the aircraft is in the flight state, the wind pressure in the air outlet ring moves the piston and the sliding tube to one end of the sealing cap, so that the sliding tube drives the connecting rod One end moves toward the sealing cap, so that the lower end of the support rod also rotates toward one end of the sealing cap, so that the landing gear is in the retracted state. When the aircraft lands, the wind pressure in the air outlet ring decreases, and the spring drives the sliding tube together with the piston to move toward the hinged seat, so that the sliding tube drives one end of the connecting rod to move toward the hinged seat, so that the lower end of the support rod moves toward the hinged seat Rotate to the limit position, so that the landing gear is in the unfolded state.

Speed, so as to realize the horizontal flight or turning of the aircraft. Since the air outlet rings located on the outer periphery of the aircraft only play the role of adjusting the attitude of the aircraft, without fans providing power, it is not easy to cause the aircraft to be damaged when the air outlet rings touch foreign objects. It is safe to lose control or cause harm to people or animals. The appearance of the aircraft is similar to a quadcopter, so it is named after the quadcopter. The four air outlet rings, the so-called "quadaxis", only play the function of adjusting the attitude, so the aircraft should be a single-axis aircraft in essence.

Further, according to the Coanda principle, the airflow ejected from the air outlet slit of the air outlet ring will flow along the deflector wall to form a conical wind film, and the conical wind film will drive the The air flows downward together, so that when the part of the air outlet slit is blocked during the flight of the aircraft, the overall airflow formed by the air outlet slit has little influence, which is beneficial to the stability of the flight attitude of the aircraft.
