Drone with extending drone arms

Abstract

The invention discloses a drone with extending drone arms. The drone with the extending drone arms comprises a drone frame, a main drone arm, an auxiliary drone arm, a screw and a screw driving unit,wherein one end of the main drone arm is fixed to the drone arm and provided in a nested mode with the auxiliary drone arm and the screw, the screw driving unit is fixed onto the drone frame, one endof the screw if connected with the screw driving unit, the other end of the screw is threadedly connected with the auxiliary drone arm, the inner wall of the main drone arm is provided with a guide unit, and the screw driving unit is used for driving the screw to rotate to drive the auxiliary drone arm to extend and retract along the guide unit; the auxiliary drone arm bears rotors of the drone. The drone with the extending drone arms also comprises a landing frame, a connecting rod and a steering engine, wherein the steering engine is fixed at the bottom of the drone frame, one end of the connecting rod is connected with the rotating shaft of the steering engine, the connecting rod is fixedly provided with the landing frame, and the steering engine drives the connecting rod to rotate around the rotating shaft and further drives the landing frame to fold and unfold. The drone with the extending drone arms has the technical advantages of being simple in structure, flexible in flight, adjustable in attitude and table in flight.

Description

technical field [0001] The invention belongs to the field of aircraft, in particular to an unmanned aerial vehicle with retractable arms. Background technique [0002] With the development of society, aircraft are used in national ecological environment protection, aerial photography, surveying and mapping, agricultural operations and other fields. Four-axis aircrafts have stable flight, strong maneuverability and high flexibility, so they have a wide range of application fields. [0003] The power of the four-axis aircraft is generated by four rotor devices, and the four rotor devices generate lift. By adjusting the rotational speed of the motor in the rotor device, different motion forms of the four-axis aircraft are realized. The main motion forms of the quadcopter include: lifting motion, pitching motion, yaw motion, etc. [0004] Most of the existing quadcopters have a complex structure, the arms and the frame are fixed, it is difficult to change the distance relative ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing quadcopters have a complex structure, the arms and the frame are fixed, it is difficult to change the distance relative to the motor during flight, and the space occupies a large volume, which is not easy to carry. When the quadcopter is flying, the feet The rack cannot be retracted automatically
