Description

technical field

[0001] This application relates to the design of unmanned aerial vehicles, and is a connection structure and connection method for realizing the rapid assembly and disassembly of the horizontal tail on the vertical tail on the unmanned aerial vehicle. Background technique

[0002] At present, the connection form of the horizontal tail and the vertical tail of the high-level tail unmanned aircraft is usually: a single ear joint is arranged on the horizontal tail beam, and a double ear joint is arranged on the vertical tail. In order to ensure the reliability of the connection, the connection between the joint and the beam Bolt connection is used. During assembly, in order to ensure the disassembly of the horizontal tail, the single ear joint of the horizontal tail and the double ear joint of the vertical tail are connected by bolts. However, this connection method has a large number of parts, heavy weight, complex assembly process, low assembly efficiency, lon...
