Connecting device for wing and fuselage of UAV

Abstract

The present invention discloses a unmanned aerial vehicle wing and body connection apparatus, which comprises a main insert wing, an assistant insert wing, a first body frame plate, a second body frame plate, a main sleeve box and an assistant sleeve box, wherein the main insert wing and the assistant insert wing are fixed on the wing, the first body frame plate and the second body frame plate are fixed on the body, the main sleeve box is fixed on the first body frame plate, and the assistant sleeve box is fixed on the second body frame plate. The main sleeve box is provided with first grooves for main insert wing passing through, and the assistant sleeve box is provided with second grooves for assistant insert wing passing through. The main insert wing is inserted in the main sleeve box along the first grooves, and is fixed by using screws. The assistant insert wing is inserted in the assistant sleeve box along the second grooves, and is fixed by using screws. The connection apparatus of the present invention has characteristics of simple and reliable structure, light weight, easy assembly and disassembly, and easy processing.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a connecting device between the wing and the fuselage of an unmanned aerial vehicle. Background technique [0002] Wing structure layout forms can be divided into beam wing, monolithic wing and multi-web wing, etc., which are suitable for different purposes and different types of aircraft. According to the layout of the wing structure, the connection methods of the wing and the fuselage can be basically divided into the following two types. One is that the wing connecting lugs and the fuselage frame connecting lugs are butted by bolts, and the butt joint is the design separation surface; Another type is that the left and right wings and the central wing run through the fuselage, and the central wing is connected with the fuselage frame. [0003] For small and medium-sized low-speed UAVs, in the structural design, the first type of connection method is usually adopted, and the wings ...

AI Technical Summary

Problems solved by technology

[0004] (1) The connection hole requires high precision, difficult processing and heavy structural weight;

[0005] (2) During the deployment and withdrawal of the UAV, the disassembly and assembly of the wings is very inconvenient, time-consuming, and requires high requirements for operators;

[0006] (3) The connecting bolts are the main load-bearing parts. When the thickness of the lugs is limited, in order to meet the extrusion strength, the connecting bolts are designed to be very thick, which directly leads to an increase in the structural weight of the UAV.
