[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model provides a tail support structure of a UAV, such as Figure 1-6 As shown, the UAV tail support structure includes: a UAV tail support body 1; a protective plate 2 arranged on the UAV tail support body 1, and the protective plate 2 is used to protect the UAV tail support body 1; a buffer frame 3 mounted on the UAV tail support body 1; a damping pad 4 fixedly installed in the buffer frame 3; a spring 5 arranged in the buffer frame 3; a connecting frame 6 slidably arranged on the buffer frame 3, and the connecting frame 6 is connected to the protective plate 2; and a mounting mechanism mounted on the UAV tail support body 1, and the mounting mechanism is used to mount the UAV tail support body 1.

[0025] It should be noted that some existing UAV tail support structures lack corresponding protection functions during actual use. When the UAV is in extreme weather conditions, the tail support will be subjected to additional stress and impact, thereby increasing the possibility of failure of the UAV tail support and reducing the overall safety of use;

[0026] In this embodiment, when the UAV tail support body 1 is used, the UAV tail support body 1 and the corresponding UAV are first connected and installed through the installation mechanism. The UAV tail support body 1 can well improve the stability of the UAV during flight. When in more extreme weather, such as heavy rain, the UAV tail support body 1 can be well protected by the protective plate 2, reducing the stress and impact force of the UAV tail support body 1 during flight, thereby playing a good protective role for the UAV tail support body 1, and then reducing the failure rate of the UAV tail support body 1. At the same time, when the protective plate 2 is subjected to external impact force, the protective plate 2 will drive the connecting frame 6 to apply force to the spring 5, and the spring 5 deforms to release energy. The damping pad 4 absorbs the energy released when the spring 5 is deformed, thereby preventing the spring 5 from being compressed and deformed too quickly, thereby playing a good buffering role for the protective plate 2, and then making the protective plate 2 have a certain buffering effect, thereby reducing the impact force on the protective plate 2, and the setting of the protective plate 2 can be set on the top or side of the UAV tail support body 1 according to the actual situation. At the same time, the installation and use of the protective plate 2 can be installed and used according to the actual weather conditions.

[0027] In a further preferred embodiment of the utility model, the mounting mechanism includes: a connecting piece 7 fixedly mounted on the top of the UAV tail support body 1, the connecting piece 7 being used to connect and mount the UAV tail support body 1 and the corresponding UAV; a bolt hole 8 provided on the connecting piece 7; a connecting bolt 9 assembled in the bolt hole 8, a connecting nut 10 being threadedly mounted on the connecting bolt 9.

[0032] In this embodiment, when using the fixing mechanism, after the buffer frame 3 is placed in the positioning frame 11, the screw rod 12 is rotated to drive the positioning block 13 to move and connect with the positioning groove 14 on the buffer frame 3, thereby fixing the buffer frame 3 in the positioning frame 11. Similarly, the screw rod 12 is rotated in the opposite direction to drive the positioning block 13 to move and disconnect the positioning groove 14, so that the buffer frame 3 and the positioning frame 11 can be disassembled, thereby facilitating the installation and disassembly of the buffer frame 3.

[0034] In this embodiment, the connection block 15 and the connection groove 16 are provided to improve the stability of the connection between the positioning frame 11 and the buffer frame 3 , and to facilitate more accurate connection of the positioning groove 14 with the positioning block 13 .

A disassembly mechanism is provided on the inspection door 19 and the UAV tail support body 1, and the disassembly mechanism is used to disassemble the inspection door 19.

[0038] In this embodiment, the inspection door 19 facilitates the inspection of the interior of the UAV tail support body 1, and the disassembly mechanism facilitates the disassembly of the inspection door 19.

[0039] In a further preferred embodiment of the utility model, the disassembly mechanism includes: a slot 20 provided on the UAV tail support body 1; a block 21 fixedly mounted on the inspection door 19, the block 21 and the slot 20 being compatible; a positioning bolt 22 threadedly mounted on the block 21 and the UAV tail support body 1, the block 21 being connected and fixed to the UAV tail support body 1 via the positioning bolt 22.

With the mutual cooperation of the buffer frame 3, the damping pad 4, the spring 5 and the connecting frame 6, the protective plate 2 can play a good buffering role, and thus the protective plate 2 has a certain buffering effect, thereby reducing the impact force on the protective plate 2.
