Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a vertical / horizontal tail docking structure with limiting and an UAV. Background Technology

[0002] Currently, most aircraft vertical and horizontal stabilizer connections use fasteners, requiring tools for assembly and disassembly, which is time-consuming and labor-intensive, making it difficult to meet the requirements for quick disassembly and reassembly. The existing method of installing the horizontal stabilizer lacks direction control, making it difficult to align the horizontal stabilizer docking joint with the vertical stabilizer docking joint, thus increasing assembly time and costs.

[0003] Because the existing technology uses a fastener-connected docking structure for the vertical stabilizer, the H-shaped integral tail fin can only be transported as a whole, which requires a large space and results in high transportation costs. Furthermore, the fastener-connected docking structure makes it time-consuming and labor-intensive to assemble and disassemble the horizontal stabilizer.

[0004] Therefore, there is a need to provide a vertical / horizontal tail docking structure with limiting and an unmanned aerial vehicle (UAV) to solve the above problems. Utility Model Content

[0005] This utility model provides a vertical and horizontal tail docking structure with limiting, which can disassemble the H-shaped tail fin into the vertical tail and horizontal tail without the use of tools during transportation, and keep the horizontal tail in a proper position during assembly to prevent collision and reduce wear, thus solving the problems of high transportation cost and time-consuming and labor-intensive disassembly and assembly of traditional vertical and horizontal tail connection methods.

[0006] The present invention provides a vertical horizontal tail docking structure with limiting, which adopts the following technical solution, including:

[0007] A flat-tail butt joint is provided on both ends of the flat tail, and mating lugs are provided on it;

[0012] Preferably, the vertical tail butt joint includes: a vertical tail connecting seat, on which a second connecting lug perpendicular to the end face of the vertical tail is provided, and two parallel second reinforcing ribs are provided on one side of the second connecting lug, and a second groove is formed between the two second reinforcing ribs and the second connecting lug; wherein the second connecting lug is connected to the first connecting lug by a bolt assembly.

[0013] Preferably, the bolt assembly includes: a bolt with a guide boss in the middle, one end of which passes through the connecting hole of the first connecting lug and is fixed by a nut, and the other end of which passes through the connecting hole of the second connecting lug.

[0014] Preferably, a bushing with a shoulder is provided in the connecting hole of the second connecting lug, wherein the bolt and the bushing with the shoulder are connected together.

[0015] Preferably, the limiting component includes a limiting pin, which is vertically connected between two second reinforcing ribs, and the distance between the limiting pin and the second connecting lug is the thickness of the first connecting lug.

[0016] Preferably, the limiting pin is a quick-release pin.

[0017] Preferably, the second reinforcing rib is arranged in the same direction as the first reinforcing rib.

[0018] Preferably, the vertical tail connector is connected to the vertical tail via a high-strength bolt, and the horizontal tail connector is connected to the horizontal tail via a high-strength bolt.

[0019] An H-shaped tail-wing unmanned aerial vehicle (UAV) includes: the vertical and horizontal tail docking structure with limiting according to the present invention.

[0020] The beneficial effects of this utility model are:

[0021] By employing the vertical and horizontal tail docking structure provided by this utility model, during the transportation of the H-type tail fin, it is only necessary to unlock the horizontal tail docking joint and the vertical tail docking joint of the vertical and horizontal tail docking structure through the limiting locking structure. This allows the H-type tail fin to be disassembled into the horizontal tail and the vertical tail, enabling independent packaging during transportation, reducing transportation space, saving transportation costs, and facilitating handling and maintenance.
