Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a wing disassembly and assembly structure of a vertical unmanned aerial vehicle. Background Art

[0002] Unmanned aircraft, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. There is no cockpit on the aircraft, but it is equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the remote control station of the mother aircraft use radar and other equipment to track, locate, remotely control, telemeter and digitally transmit it. It can take off like an ordinary aircraft or be launched into the air with a booster rocket under radio remote control, or it can be taken into the air by the mother aircraft for flight. When recovered, it can land automatically in the same way as an ordinary aircraft landing process, or it can be recovered by remote control with a parachute or a blocking net. It can be used repeatedly many times. It is widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic interference, etc.

[0003] After installation, the fuselage and wings of the existing vertical take-off UAV are fixed. After installation, there will be wires on the inside of the wing. After installation, this integrated vertical take-off UAV wing is not convenient to disassemble or replace, and it takes up additional space during mobile transportation. At the same time, it is not convenient to disassemble and assemble during maintenance. Utility Model Content
