Combined type rotor unmanned aerial vehicle

Abstract

The invention discloses a combined type rotor unmanned aerial vehicle comprising a fuselage, an undercarriage and vehicle arm assemblies. The vehicle arm assemblies are provided with vehicle arms andpropellers, wherein the propellers are located at the tail ends of the vehicle arms; a vehicle seat is arranged on the fuselage and provided with extending connecting pipes; the connecting pipes are provided with first through holes perpendicular to the center lines of the connecting pipes; extending connecting columns and annular grooves matched with the connecting pipes are formed in the ends, away from the propellers, of the vehicle arms; the vehicle arms are provided with second through holes perpendicular to the center lines of the connecting columns; and during assembly, the connecting pipes of the vehicle seat extend into the annular grooves of the vehicle arms, meanwhile the connecting columns of the vehicle arms extend into the connecting pipes of the vehicle seat, and inserting of quick-detaching positioning pins can be guaranteed through the positions of the first through holes in the connecting pipes and the positions of the second through holes in the vehicle arms. According to the combined type rotor unmanned aerial vehicle adopting the structure, the vehicle arm assemblies can be detached and carried conveniently, the damaged vehicle arm assemblies can be replaced conveniently, transport is facilitated, damaged pieces can be replaced rapidly, the maintenance cost for the damaged unmanned aerial vehicle falling abnormally is reduced, and the using cost of a user is reduced.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a combined rotor unmanned aerial vehicle. Background technique [0002] The rotor UAV includes a fuselage, a landing gear and an arm assembly. The arm assembly has an arm and a propeller. The propeller is located at the end of the arm. The fuselage and the arm are usually made of carbon fiber, and the arm is not detachable. During the process, due to the vibration of the aircraft or touching some objects, it is easy to cause damage to the fuselage arm. Because the arm is not detachable, it is very inconvenient to repair the drone. When taking the aircraft to the place where it needs to be used During the process, due to the large size of the drone, it is easy to damage the drone. Foldable drones have appeared now, basically using carbon fiber fuselage, and the folded parts are made of aviation aluminum. After folding, the volume is small and convenient for transportation, but they are mo...
