Cargo unmanned aerial vehicle has characteristics such as fast, efficient and flexible, and can quickly complete cargo transportation across geographical natural barrier. Most unmanned aerial vehicles on the market have small load quantity, and the number of goods distributed each time is limited, so multiple round trips are needed to pick up goods, which greatly increases distribution cost. When carrying out large load, medium and long distance branch line transportation, light weight, large capacity and low cost are important design factors that need to be considered in cargo unmanned aerial vehicle design.
[0003] In order to reduce weight and cost, the structure form, material selection and processing mode of the body wallboard with large proportion must be considered for large-tonnage cargo unmanned aerial vehicle. In order to reduce cost and improve maintainability, the wallboard generally adopts metal structure, and the structure form of skin plus longeron is mostly used. The number of longerons is large. When the longeron passes through the partition frame, a through hole needs to be opened on the partition frame, and the strength and stiffness of the partition frame are greatly weakened due to the low height of the unmanned aerial vehicle partition frame. Therefore, it is hoped to design a cargo compartment with light weight, simple structure, low cost, maximum cargo volume rate and the like. SUMMARY

The upper wallboard, the right side wallboard, the lower wallboard and the left side wallboard form a rectangular cargo compartment wallboard. The upper wallboard, the right side wallboard, the lower wallboard and the left side wallboard are all provided with a plurality of reinforcing bars. A plurality of longerons are arranged on the rectangular cargo compartment wallboard. The rectangular cargo compartment wallboard is covered with a skin.
[0007] Further improvement of the utility model lies in that the reinforcing bars of the upper wallboard, the right side wallboard and the left side wallboard are outwardly directed.
[0008] Further improvement of the utility model lies in that the reinforcing bars of the lower wallboard are inwardly directed.
[0009] The further improvement of the utility model lies in that the skin is an aluminum alloy skin with equal thickness.
[0010] The further improvement of the utility model lies in that the longeron is used for connecting the upper wall plate, the right side wall plate, the lower wall plate and the left side wall plate into a rectangular cargo hold wall plate.
[0011] The further improvement of the utility model lies in that a partition frame is arranged on the rectangular cargo hold wall plate.
[0012] The second aspect, the utility model provides a kind of unmanned aerial vehicle using cargo hold wall plate structure, including unmanned aerial vehicle fuselage structure, rectangular cargo hold wall plate is placed in unmanned aerial vehicle fuselage structure.
[0013] The further improvement of the utility model lies in that one end of unmanned aerial vehicle fuselage structure is provided with a nose cover, and the other end is provided with a tail cover.
[0014] Compared with prior art, the utility model has the beneficial effects that:
[0015] The utility model can improve the strength and rigidity of the skin by pre-pressing several reinforcing stems on the upper wall plate, the right side wall plate, the lower wall plate and the left side wall plate, and can reduce the use of longeron during installation, which not only ensures the overall structural performance, but also reduces the height of the partition frame and improves the volume rate of the cargo hold due to the reduction of longeron. Compared with the existing structure, the utility model reduces the number of parts, lightens the weight of the machine structure and reduces the assembly cost.
[0016] Further, the skin of the utility model is an aluminum alloy skin with equal thickness, which reduces the additional processing cost caused by the thickness of the skin. BRIEF DESCRIPTION OF DRAWINGS
