The upper bracket 902 is connected to the fan installation part above the air outlet pipe, and the upper driving fan 951 is installed on the upper bracket; the lower bracket 903 is connected to the fan installation part below the air outlet pipe, and the lower bracket A lower drive fan 952 is installed on the top; the direction of the upper drive fan is opposite to that of the lower drive fan, and the inner diameter of the upper drive fan part installed in the fan installation part is larger than the inner diameter of the lower drive fan part installed in the fan installation part, and the fan installation The wind pressure inside the upper drive fan and the lower drive fan is higher than the atmospheric pressure, so that the wind pressure is formed in the air outlet ring.

The inner periphery of the air outlet ring is formed with an air outlet slit 912 with the opening facing downwards. The inner periphery of the air outlet ring is located below the air outlet slit and is a diversion wall 913 with a narrow top and a wide bottom. The cone angle of the surface is 10-20 degrees; the upper end of the diversion wall is connected with an inwardly curved wall 914 with a wide top and a narrow bottom, and the cone angle of the conical surface where the inwardly curved wall is located is 15-25 degrees.

The axial direction of the air outlet ring is perpendicular to the radial direction of the fan installation part, and an included angle of 5-20 degrees is formed between the axial direction of the air outlet ring and the horizontal direction, and the air blown from the air outlet slit of the air outlet ring The generated horizontal force is opposite to the direction of rotation of the blades of the upper driving fan.

The upper driving fan, the lower driving fan and each motor are respectively electrically connected to the control circuit board.

In the present invention, the driving force is provided by 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 gap of each air outlet ring, and the distance of each air outlet ring relative to the main body is adjusted by combining each motor. 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 quadcopter, so it is named after the quadrocopter. The four air outlet rings are the so-called "quadrocopters" that only function to adjust the attitude, so the present invention is essentially a single-copter.

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 offset the reaction force generated when the upper drive fan, or the upper drive fan and the lower drive fan rotate; and, by simultaneously controlling the forward and reverse rotation of each motor to change the output The distance between the wind ring and the main body (adjusting the size of the moment arm) can realize the overall forward or reverse rotation of the aircraft. By adjusting the distance between one or two adjacent wind outlet rings relative to the main body, the aircraft can be tilted as a whole, so that the aircraft can be driven to fly in a horizontal direction.

The air outlet ring part is lighter in weight than the main body, and when the distance between a certain air outlet ring and the main body increases, the height of the location of the air outlet ring rises.

The lower periphery of the fan mounting part is a battery mounting part, and the battery mounting part is connected with a storage battery 92 electrically connected to the control circuit board; the fan mounting part is located above the battery mounting part and is a circuit board mounting cavity 904, so The control circuit board is installed in the circuit board installation cavity; the upper end surface of the circuit board installation cavity is uniformly formed with an air inlet hole 905 communicating with the fan installation part, and the outer wall of the circuit board installation cavity is uniformly formed with an exhaust hole 906.

A small amount of air flow from the fan installation part enters through the air inlet hole and is discharged through the air outlet hole, so as to dissipate heat on the control circuit board.

The upper end of the main body is connected with an air inlet cover 94 in the shape of a semi-ellipsoid, and strip-shaped air inlets are evenly formed on the air inlet cover.

The outer wall of the air outlet pipe is formed with more than one guide slide bar arranged along the length direction, and the inner wall of the socket pipe is formed with a guide chute slidingly connected with the guide slide bar.

Example 3

With reference to Figure 13 and Figure 14, this embodiment also makes the following improvements on the basis of Embodiment 2: a landing gear joint 915 is formed at the lower part of the inner circumference of each of the air outlet rings away from the air outlet pipe, and each of the landing gear joints Each is connected with a landing gear 93; the landing gear includes an air outlet pipe body 931 that is fixedly connected with the landing gear joint and communicates with the inside of the air outlet ring through the landing gear joint, and the sliding pipe that is slidably installed in the air outlet pipe body 932, the support rod 935 that is rotatably connected to the end of the air outlet pipe body near the landing gear joint, the roller 936 that is connected to the magnetic material on the support rod away from the end of the landing gear joint, and the rotatable connection with the middle part of the sliding tube and the middle part of the support rod respectively. Connecting rod 934.

A hinge seat 9311 is formed on the side wall of the air outlet pipe close to the landing gear joint, and one end of the support rod is rotatably connected to the hinge seat; a piston 9321 is connected to the end of the sliding tube close to the landing gear joint, and the middle part of the outer wall of the sliding tube The position is connected with a hinged joint 9322, one end of the connecting rod is rotationally connected with the hinged joint, and the side wall of the end of the air outlet pipe body away from the landing gear joint is formed with a bar-shaped opening 9312 for the hinged joint to pass through; the air outlet pipe One end of the body away from the landing gear joint is fixedly connected with a sealing cap 933, and the inner end of the sealing cap is integrally connected with a spring positioning rod 9331, and a spring 937 is sleeved on the spring positioning rod, and the two ends of the spring are respectively against the piston and the sealing cap. Between the inner ends of the cap; the support rod is formed with a connecting rod accommodation groove 9351 for accommodating the connecting rod when the support rod is in a retracted state.

When the spring is in the extended state, the support rod is in the unfolded state, and after the upper driving fan is in the working state, the air pressure driving piston in the air outlet ring moves together with the sliding tube to make the support rod in the retracted state.

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.

The strip-shaped mouth plays a role in restricting the hinge joint on the sliding tube. The position of the end of the strip-shaped mouth is just such that after the spring is elongated, the support rod rotates to be perpendicular to the horizontal direction and then continues to rotate 3-10 degrees, so that after the aircraft lands , each support rod is in a stable state.

After the landing gear is unfolded, each roller just sucks tightly to locate the position of the magnetic ring on the parking platform, which is beneficial to the positioning of the aircraft and the connection between the suspension component and the battery unit.
