Unmanned aerial vehicle rotor wing, rotor wing assembling method and rotor wing type unmanned aerial vehicle

Abstract

The invention relates to an unmanned aerial vehicle rotor wing and a rotor wing type unmanned aerial vehicle. An unmanned aerial vehicle body is provided with an installing groove. The upper portion of the installing groove is fixedly connected with a groove cover. Paddles are arranged above the groove cover. An inner tooth ring, an outer tooth disc and a motor are arranged in the installing groove. The inner tooth ring is fixed to the inner bottom wall of the installing groove. The inner surface of the inner tooth ring is engaged with the outer tooth disc. The motor is fixed to the upper surface of the outer tooth disc. An output shaft of the motor is upwards connected with a rotation shaft. A center hole is formed in the center position of the groove cover. The paddles are provided witha downward connecting shaft. The lower end of the connecting shaft penetrates through the center hole. A connecting groove is formed in the lower end of the connecting shaft. The rotation shaft is inserted in the connecting groove. Inner threaded grooves the same in size are formed in the upper portion of the connecting shaft and in the rotation shaft. A high-strength bolt penetrates through the connecting shaft and the rotation shaft from top to bottom, and the upper end is locked through a nut. The unmanned aerial vehicle rotor wing and the rotor wing type unmanned aerial vehicle well solvethe problem about connection between the unmanned aerial vehicle body and the rotor wing, connection is firm, flexibility is high, unmanned aerial vehicle rapid disassembling and assembling, componentreplacement and other requirements can be well met.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle rotor, a method for assembling the rotor and a rotor-type unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, it is widely used in aerial photography, agriculture, plant protection, micro-selfie, express transportation, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, e...

AI Technical Summary

Problems solved by technology

[0004] When the rotor mechanism of the existing rotor UAV is installed, the motor and the blades are usually installed together by welding, and the motor is directly welded to the fuselage of the UAV, which may cause maintenance problems during the maintenance process. Inconvenient, unable to quickly disassemble or replace parts for maintenance

Due to the lack of flexibility, welding disassembly is easy to damage the drone or rotor mechanism

In addition to the fixed welded structure, there are also a few rotary-wing UAVs that are connected in a detachable way, but the firmness of the connection is often not satisfactory

The firmness and flexibility of the rotor connection cannot be achieved at the same time, which has brought constraints to the development of rotor UAVs
