[0018] This utility model embodiment provides a quick-release mechanism for the powered arm of a compound-wing unmanned aerial vehicle, such as... Figure 1-7As shown, it includes a power arm 1, a wing 2, a guide 3, a snap-fit ​​4, and a connector 5; one end of the guide 3 is connected to the wing 2, and the other end of the guide 3 is slidably snapped into the snap-fit ​​4; the end of the snap-fit ​​4 away from the wing 2 is sleeved on the power arm 1, and the snap-fit ​​4 can be fixedly connected to the power arm 1; the guide 3 is fixedly connected to the snap-fit ​​4 through the connector 5.

[0019] For example, this application achieves a reliable connection between the wing 2 and the power arm 1 by inserting the snap-fit ​​4 into the guide 3 from one side and connecting it with the connector 5. This does not require the use of tools. The quick-release mechanism of this application has a simple structure and reliable function, enabling tool-free operation of the assembly and disassembly of the power arm 1 of the compound wing UAV, reducing the difficulty of operation and having a wide range of applications.

[0020] In the embodiments of this application, such as Figure 1-7 As shown, it also includes a wing support 6; the guide 3 is connected to the wing 2 via the wing support 6.

[0021] For example, the wing support 6 is connected to the front and rear beam webs of the wing 2 by bolts respectively; the quick-release mechanism of this application is provided in two sets, one set is connected to the front beam webs of the power arm 1 and the wing 2 respectively, and the other set is connected to the rear beam webs of the power arm 1 and the wing 2 respectively.

[0022] In the embodiments of this application, such as Figure 1-7 As shown, the guide member 3 has a guide groove 31 in the length direction of the power arm 1; the guide member 3 has a limit structure 32 at the end of the guide groove 31.

[0023] In the embodiments of this application, such as Figure 1-7 As shown, the guide groove 31 is configured as a wedge-shaped groove.

[0024] In the embodiments of this application, such as Figure 1-7 As shown, the snap-fit ​​component 4 includes a connecting part 41, a snap-fit ​​part 42, and a boss 43; the connecting part 41 is sleeved on the outside of the power arm 1 and can be fixedly connected to the power arm 1; the connecting part 41 is radially connected to the snap-fit ​​part 42, and the snap-fit ​​part 42 can be slidably snapped into the guide 3; the two sides of the snap-fit ​​part 42 are symmetrically connected to the boss 43, and the boss 43 can be slidably connected in the guide groove 31.

[0025] In the embodiments of this application, such as Figure 1-7 As shown, the connector 5 includes a quick-release pin 51 and a limiting post 52; the quick-release pin 51 is symmetrically connected to the limiting post 52 on its outer side; the guide 3 has a connecting hole and the snap-fit ​​4 has a limiting hole; the quick-release pin 51 passes through the connecting hole and the limiting hole in sequence and connects the guide 3 and the snap-fit ​​4, and is snapped on one side of the guide 3 by the limiting post 52.

[0026] In the embodiments of this application, such as Figure 1-7 As shown, the limiting post 52 can extend and retract along the radial direction of the quick-release pin 51.

[0027] For example, the connection method between the limiting post 52 and the quick-release pin 51 is similar to the connection method of the ball head plunger.

[0028] For example, firstly, the wing support 6 is bolted to the front spars web and the rear spars web of the wing 2. During assembly, the positional accuracy of the wing support 6 must be ensured. The guide 3 is mounted on the side of the wing support 6 away from the wing 2, and the positional accuracy of the guide groove 31 must be ensured during assembly. Two snap-fit ​​pieces 4 are installed at intervals on the power arm 1. They are connected by adhesive and then screwed on to secure the snap-fit ​​pieces 4 to the power arm 1. The snap-fit ​​pieces 4, after being installed with the power arm 1, are aligned with the guide 3 and pushed into the corresponding guide groove 31 from front to back. The connector 5 then limits the movement, thus achieving tool-less assembly of the power arm 1. When disassembling the power arm 1, only the connector 5 needs to be pulled out to separate the snap-fit ​​pieces 4 from the corresponding guide 3, thus achieving tool-less disassembly of the power arm 1.

[0029] For example, this application enables tool-free quick assembly and disassembly of the power arm 1 through simple operation, making it more convenient for users. The quick-disassembly mechanism of this application has the advantages of reliable structure and quick and convenient assembly. The inventors have used mechanical principles and other related knowledge to reasonably design the load-bearing structure, thereby reducing the difficulty of user operation and ensuring functional reliability.
