[0020] (2) The one-piece convex plate and concave plate plug-in structure can ensure good sealing performance and prevent external dust, moisture and other impurities from invading the interior of the drone. This is of great significance for protecting the key components and equipment inside the drone and extending its service life.

[0021] (3) The structural design of the outer edge extension plate, inner lining plate and outer lining plate of the tail cone door, as well as the coordination of the convex and concave plates, make the fuselage surface simple and complete without excessive door frame lines, which can reduce the resistance and turbulence during air flow, thereby improving flight speed and stability.

[0022] (4) The design of the tail hatch door locking screw can not only effectively prevent the hatch from accidentally opening or loosening, thus reducing the risk of accidents, but also allow the hatch to be quickly closed and opened, thus saving maintenance time and improving efficiency, making the maintenance and overhaul of the UAV more convenient.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figures 1 to 6 The present application is further described in detail with specific implementation methods.

[0034] A tail hatch of an unmanned aerial vehicle, comprising:

[0035] Tail hatch door 1: fixedly connected to the fuselage cabin 2, serving as the main structure of the entire cabin door.

[0036] The first convex plate 3 is formed integrally with the fuselage cabin 2 through a special process, which increases the strength of the structure and reduces the weight. It includes an outer edge extension plate 31, an inner lining plate 32 and an outer lining plate 33, which are formed into a whole through advanced connection technology. Among them, a plurality of first locking holes 5 are provided on the outer edge extension plate 31, and these holes are used to fix the locking screws 7.

[0037] The first concave plate 4 is formed integrally with the tail hatch 1 by a special process, and includes a slot 41, an inner plate 42 and an outer plate 43. There is a gap between the inner plate 42 and the outer plate 43, forming the structure of the slot 41. The inner plate 42 and the outer plate 43 are both provided with a plurality of second locking holes 6, which correspond to the first locking holes 5 on the first convex plate 3.

[0038] Locking screw 7: It is a special structure screw, including an adjusting nut 71, an expansion leg 72, an adjusting spring 73 and a boss 74. The adjusting nut 71 is fixedly connected to one end of the adjusting spring 73, and the other end of the adjusting spring 73 is fixedly connected to the expansion leg 72. When the adjusting nut 71 is stretched, the adjusting spring 73 drives the expansion leg 72 to close. The boss 74 is designed to prevent the expansion leg 72 from accidentally falling out during operation.

[0039] Installation and disassembly process: First, insert the outer edge extension plate 31 into the slot 41. The spacing of the slot 41 is the same as the thickness of the outer edge extension plate 31 to ensure a tight fit. The outer lining plate 33 and the outer layer plate 43 have the same thickness, which ensures the streamlined shape of the drone fuselage cabin 2 after being connected to the tail vertebrae cabin door 1, which can reduce the resistance and turbulence during air flow and improve the flight speed and stability. Then, align the first locking hole 5 with the second locking hole 6, and insert the locking screw 7 in turn, and the tail vertebrae cabin door 1 will be firmly closed. If you want to open the tail vertebrae cabin door 1, you only need to stretch the adjusting nut 71 to tighten the adjusting spring 73, drive the expansion leg 72 to retract, and the locking screw 7 will then disengage from the locking hole, and the tail vertebrae cabin door 1 can be easily opened. This design realizes the rapid disassembly and assembly of the tail vertebrae cabin door 1.
