Bidirectionally-transformable unmanned aerial vehicle of H-shaped structure

Abstract

The invention discloses a bidirectionally-transformable unmanned aerial vehicle of an H-shaped structure. The bidirectionally-transformable unmanned aerial vehicle of the H-shaped structure comprises a fuselage and arms which are arranged on the two sides of the fuselage and are parallel to each other. A lifting structure is arranged in the middle of the fuselage. The lifting structure is connected with oblique T-shaped parts through transverse stress pipes, and the oblique T-shaped parts are fixed to the middle portions of the arms correspondingly. Rotor wing assemblies are arranged at the two ends of each arm correspondingly. According to the bidirectionally-transformable unmanned aerial vehicle of the H-shaped structure, the lifting structure is additionally arranged on the fuselage so that the arms of the unmanned aerial vehicle can rise and fall, the center of the unmanned aerial vehicle can be better adjusted, the unmanned aerial vehicle can adapt to various complex high-altitude environment, and the stability of the unmanned aerial vehicle is improved; the unmanned aerial vehicle can be protected against disturbance from the arms when executing shooting work, and the shooting effect of the unmanned aerial vehicle is improved; and folding of the fuselage and the arms of the unmanned aerial vehicle is achieved, the arms and the fuselage of the unmanned aerial vehicle can be folded together in the unmanned aerial vehicle transporting process, the size of the unmanned aerial vehicle is reduced, the assembled and debugged unmanned aerial vehicle can be directly used conveniently when needed, and the practicability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an H-shaped structural bidirectionally deformable unmanned aerial vehicle frame. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parawing aircraft, etc. UAVs can carry a variety of loads to complete various complex tasks, and are widely used in many fields such as photography, pesticide spraying, fire prevention and disaster relief, communication, and anti-drug.

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing UAV is relatively simple, and the arm and the body are both fixed structures. During the flight, the UAV is easily affected by the external environment and loses stability. Some UAVs that perform camera tasks need to install a camera , due to the inability to maintain a relatively stable flight, it is easy to shoot the arm, which greatly affects the shooting effect, greatly prolongs the operation time of the drone, and increases the mission cost of the drone

At the same time, due to the fixing of the body and the arm, the volume of the drone is very large. Every time it is used, it needs a large transportation tool for transportation, or the drone is disassembled. The parts are delivered to the designated place and then assembled. After the assembly is completed, debugging is required before normal use, which is very inconvenient. This greatly restricts the use of drones and affects the development of drones.
