Description

Drone docking structure

The present invention relates to a docking structure of a drone, and more specifically, to a docking structure of a drone that stably accesses and docks luggage to be moved, and can be firmly fixed and coupled so that luggage does not fall when moving. .

Unmanned aerial vehicles such as drones are remotely controlled from the ground without humans getting on the aircraft, and are structured to generate thrust by generating thrust as the propeller rotates by receiving the rotational force of the driving motor.

These unmanned aerial vehicles generally have a plurality of propellers on both sides of the front and rear of the body, and the user controls the operation of the propeller so that the aircraft is flying in the air.

In this way, the flying principle of a drone using a plurality of propellers is that the propeller rotates in different directions by two pairs facing each other in a diagonal direction, so that the fuselage rises, and in this state, only the rotation speed of each propeller is separately controlled to free the flight direction. It will be changed to material.

In other words, when a plurality of propellers rotate at high speed, they rise in place, and when they rotate at low speed, they fall, and when the rotation speed of the rear propeller in the desired direction is increased, the aircraft tilts forward and moves in the inclined direction. .

As described above, the flight method using a plurality of propellers is very simple and can be easily understood and operated by the user. However, if the rotational speed of any one of the plurality of propellers is lower than the speed set by the user or stops at all, the fuselage is balanced. Without catching it, it is thrown to one side and falls directly to the ground in the air.
