The transmission gear a is in meshing transmission connection with the driving gear, and the transmission gear b is in meshing transmission connection with the rack.

A tension spring 933 for pulling the rack to close the two door bodies is connected between one end of the rack, which is far away from the door bodies, and the inner wall of one end of the box body, which is far away from the door bodies.

The whole driven gear is in a fan shape with a central angle of 80-100 degrees, and when one end of the driven gear is abutted against the inner wall of the box body, the door body is just in a closed state; and when the door body is in a closed state, the tension of the tension spring is greater than zero.

When the aircraft assembly is in a flight state, the two first air outlet rings are positioned on the same horizontal plane; and the two second air outlet rings incline towards the same first air outlet ring direction to generate horizontal thrust.

The control mode of the control circuit board of the unmanned aerial vehicle is similar to that of a conventional four-axis aircraft, the control of the lifting of the aircraft is realized by controlling the rotating speeds of the upper driving fan and the lower driving fan, the rotation of the aircraft is realized by controlling the rotating speeds of the upper driving fan and the lower driving fan to be different, and the control of the inclination angle of the second air outlet ring can also be realized. When the invention is in a flying state, the invention can be kept horizontal by adjusting the relative positions of the four air outlet rings and the main body part through linear ultrasonic waves, and the flying speed of the invention can be adjusted by adjusting the inclination angle of the annular ultrasonic motor and the rotating speed of the upper and lower driving fans. The key to the present invention lies in the modification of the structure and the execution components, and the specific control circuit and the program part are not substantially improved and are not the main point of the present invention, so that the description thereof is not repeated herein.

In addition, the lower end of the main body part is at least provided with a camera at one side corresponding to the door body, and the camera is used for manually or automatically monitoring the parking state of the aircraft assembly and the unloading state of the cargo carrying bin assembly.

The unmanned aerial vehicle disclosed by the invention generates high-speed airflow by driving the fan up and down in the fan seat, and the airflow is sprayed downwards through the four air outlet rings to form power. Because each air outlet ring is internally provided with no fan for providing power, the air outlet ring is not easy to cause the aircraft to be out of control or harm people or animals when being touched by foreign objects, and the safety is good.

Furthermore, the air current of air-out gap spun of air-out ring can flow along the water conservancy diversion wall according to the principle of coanda, forms a conical wind membrane, and conical wind membrane can drive the air of air-out ring internal week and flow downwards in the lump, and when the part of air-out gap received blockking in-process air-out gap of aircraft flight like this, the whole air current that the air-out gap formed influences for a short time, is favorable to the stability of aircraft flight gesture.

The existing four-axis aircraft mostly flies in an inclined attitude so as to enable horizontal component force generated by a fan to realize horizontal flight. In order to enable the cargo compartment assembly to be kept in a horizontal state as far as possible so as to avoid accidental damage to the loaded cargo, the aircraft assembly is wholly in a horizontal state in the flight process, namely the two first air outlet rings enable the aircraft assembly to be kept horizontally in the front and back direction by adjusting the distance between the two first air outlet rings and the main body part, the two second air outlet rings enable the aircraft assembly to be kept horizontally in the left and right direction by adjusting the distance between the two second air outlet rings and the main body part, meanwhile, the two second air outlet rings rotate towards the rear lower part of the flight direction of the aircraft assembly, and the aircraft assembly is driven to horizontally fly through a horizontal component formed by the air blown out by the two second air outlet rings.

Furthermore, control circuit board and lithium cell are installed in the mount pad drive fan and the first position of going out between the tuber pipe, cool off through the air current that the drive fan produced, effectively avoid control circuit board and lithium cell during operation high temperature.

The opening of the lower air inlet guide cover faces upwards, so that the lower driving fan sucks air from the upper part of the aircraft component, and a negative pressure area is formed above the lower air inlet guide cover, so that the aircraft component can generate lift force.

The cabinet door of the cargo compartment assembly is in a normally closed state under the action of the tension spring, and only when the aircraft assembly is in a stop state, the ratchet mechanism is driven by the reverse rotation of the lower motor to drive the cabinet door to be opened by the matching of the gear and the rack, so that the cargo can be loaded and unloaded conveniently. Lower motor not only cooperates the motor to reach the pivoted function of control aircraft subassembly, and lower motor still is used for opening of cabinet door, reaches the effect of two functions of a part, and structural design is ingenious.

In addition, when unloading, make aircraft subassembly and carry the goods storehouse subassembly to form the tilt state through undercarriage cooperation annular ultrasonic motor, for the taking out or the automatic roll-off of goods provide convenience, and do not additionally increase drive unit, structural design is ingenious.

Example 3

With reference to fig. 13, the present embodiment is modified from embodiment 2 as follows: two landing gears 88 which are integrally U-shaped are fixedly mounted at the lower ends of the second air outlet rings, when unloading is carried out, the aircraft assembly is in a parking state through the landing gears as a support, and the two annular ultrasonic motors rotate to enable one sides of the openings of the box bodies of the cargo bin assemblies to incline downwards so that the cargoes slide out of the box bodies.
