Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles, and particularly relates to a detachable wing skeleton of an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle, abbreviated as "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self-contained program control device. In fact, UAVs are a general term for unmanned aerial vehicles. From a technical perspective, they can be classified into several categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned parafoil aircraft.

[0003] However, the wings of current UAVs cannot be retracted, which is inconvenient for storage. In addition, the wing skeletons are not detachable, and the entire UAV may be forced to be discarded due to damage to the wing skeletons, which is a waste of resources. Therefore, in view of this technical problem, the present application proposes a detachable wing skeleton for an unmanned aerial vehicle. Summary of the Utility Model

[0026] Refer to Figures 1-7, An embodiment provided by the present utility model: A detachable wing skeleton for a drone, including a drone body 1. Grooves are provided at the four corners of the drone body 1. A main robotic arm 2 is fixedly connected inside the grooves. A secondary robotic arm 3 is connected inside the main robotic arm 2 through a telescopic component. The secondary robotic arm 3 is connected to a wing 4 through a buckle component. A rotating shaft 6 is fixedly connected to the end of the wing 4, and a propeller 5 is fixedly connected to the top of the rotating shaft 6. The telescopic component includes a first telescopic rod 9 fixedly connected to the rear end inside the secondary robotic arm 3. A first spring 10 is sleeved on the outer wall of the first telescopic rod 9. The front end of the first telescopic rod 9 is fixedly connected to a first buckle post 8. A lever 7 is fixedly connected to the left side of the first buckle post 8. One end of the first spring 10 is connected to the inner rear side of the secondary robotic arm 3, and the other end of the first spring 10 is connected to the rear side of the first buckle post 8. First circular holes are provided at the left and right ends of the front side of the main robotic arm 2, and the first buckle post 8 is in interference fit in the first circular holes;

[0027] Specifically, by pressing the lever 7, the first buckle post 8 is disengaged from the first circular hole, so that the secondary robotic arm 3 can slide inside the main robotic arm 2, so that the secondary robotic arm 3 contracts into the main robotic arm 2. Then, the lever 7 is released, and the first spring 10 drives the first telescopic rod 9 to push the first buckle post 8 into the first circular hole, thereby completing the function of fixing the position of the secondary robotic arm 3 inside the main robotic arm 2, so that the drone can reduce the space by the contraction of the main and secondary robotic arms, which is convenient for storage.

[0028] The buckle component includes four buckle pieces 11 located at the front side inside the secondary robotic arm 3 and fixing columns 14 located on the upper and lower sides of the wing 4. The buckle pieces 11 are slidably connected to the front side inside the secondary robotic arm 3. The fixing columns 14 are fixedly connected to the upper and lower sides of the wing 4. Second telescopic rods 15 are fixedly connected to the front and rear sides of the fixing columns 14. A second buckle post 16 is fixedly connected to the end of the second telescopic rod 15. A second spring 13 is sleeved on the outer wall of the second telescopic rod 15. One end of the second spring 13 is connected to one side of the fixing column 14, and the other end of the second spring 13 is connected to one side of the second buckle post 16. A dial 12 is fixedly connected to the top of the second buckle post 16. Second circular holes are provided at the left ends of the buckle pieces 11, and the second buckle post 16 is in interference fit in the second circular holes. Strip-shaped grooves are provided at the upper and lower sides of the left end of the secondary robotic arm 3, and the upper and lower sides of the right end of the wing 4 are in interference fit in the strip-shaped grooves;

[0029] Specifically, by pressing the paddle 12, the second snap post 16 is disengaged from the second round hole, so that the snap piece 11 can be retracted into the secondary robotic arm 3, and thus the wing 4 can be detached from the secondary robotic arm 3. When installing the wing 4 onto the secondary robotic arm 3, insert the right end of the wing 4 into the strip groove post at the left end of the secondary robotic arm 3, then move the snap piece 11 to the maximum distance, and then press the paddle 12 to align the second snap post 16 with the position of the second round hole, and then release the paddle 12 to make the second snap post 16 enter the second round hole, thereby completing the installation and disassembly of the wing 4 and the secondary robotic arm 3, enabling the wing 4 to be detachable, preventing the entire drone from being unusable due to wing damage, and thus saving some resources.

[0030] Working principle: By pressing the paddle 12, the second snap post 16 is disengaged from the second round hole, so that the snap piece 11 can be retracted into the secondary robotic arm 3, and thus the wing 4 can be detached from the secondary robotic arm 3. When installing the wing 4 onto the secondary robotic arm 3, insert the right end of the wing 4 into the strip groove post at the left end of the secondary robotic arm 3, then move the snap piece 11 to the maximum distance, and then press the paddle 12 to align the second snap post 16 with the position of the second round hole, and then release the paddle 12 to make the second snap post 16 enter the second round hole, thereby completing the installation and disassembly of the wing 4 and the secondary robotic arm 3. When storage is needed, by pressing the lever 7, the first snap post 8 is disengaged from the first round hole, so that the secondary robotic arm 3 can slide inside the primary robotic arm 2, and thus the secondary robotic arm 3 is retracted into the interior of the primary robotic arm 2, and then release the lever 7, so that the first spring 10 drives the first telescopic rod 9 to push the first snap post 8 into the first round hole, thereby completing the function of fixing the position of the secondary robotic arm 3 inside the primary robotic arm 2, enabling the drone to reduce space through the contraction of the primary and secondary robotic arms and facilitating storage.
