Description

Technical Field The invention relates to the technical field of unmanned aerial vehicles, in particular to a plug-in assembly structure and an unmanned aerial vehicle with composite wing. Background Unmanned Aerial Vehicle is an unmanned aircraft controlled by radio remote control equipment and its own program control device. The UAVs in the prior art are mainly comprising fixed wing UAVs, multi rotor UAVs and composite wing UAVs. In practical use, fixed wing UAVs and multi rotor UAVs have their own advantages. The fixed wing UAVs have the characteristics of long endurance and high altitude flight, and are widely used in surveying and mapping, geology, petroleum, agriculture and forestry industries. The multi rotor UAVs can take off and land vertically and hover in fixed space, which are mainly applicable to low altitude, low speed, vertical takeoff and landing, and hover operations. With the rapid development of UAV technology, the function of UAV has improved a lot, which has been deeply integrated into the operation of various industries. However, the complexity of UAV's application also poses a higher challenge to the structure and performance of UAV. At present, the UAV with composite wing has the advantages of both vertical takeoff and landing capability and long endurance flight, so the UAV with composite wing has gradually become the focus of the UAV field. Although the UAV with composite wing has the advantages of fixed wing UAV and multi rotor UAV, it also has structural redundancy, thus resulting in many problems. The UAV with composite wing is usually large in size, and the existing technology adopts the design of multi segment structure, that is, the UAV with composite wing is designed into a multi segment structure including wings, fuselage and tail. Multi segment structures need to be assembled before in use, especially the assembly of the electrical system. The assembly process is complex, and the cables of the electrical system are severely damaged by body vibration, which is not convenient for the repeated disassembly and use of the UAV with composite wing. US 2020/ 353 959 A1 relates to an electrical train coupling having two coupling halves. KR 2005/ 0 029 871 A relates to pole for a tent.
