[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. Compared to manned aircraft, UAVs are often more suitable for missions that are too dangerous. UAVs can be divided into military and civilian applications, including aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romance, among other applications.
[0003] In existing technologies, after a drone is used, it needs to be recycled and stored for easy carrying and use. During recycling, the drone's arms need to be folded to reduce its size. However, the drone arms are easily damaged during use, and the existing arm disassembly is cumbersome and makes it inconvenient to replace the arm folding mechanism. Therefore, improvements are needed. Utility Model Content

[0027] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a drone arm folding mechanism.
[0028] A folding arm mechanism for a drone includes a body 1, a support block 2, and a support column 3, with the support block 2 fixedly connected to the body 1. It also includes: a support groove 4 formed on the support block 2; multiple support legs 5 symmetrically arranged on the body 1 and fixedly connected to it; a support plate 6 mounted on the support column 3 and rotatably connected to it; a drive block 7 slidably connected to the support plate 6; a support shaft 8 mounted on the drive block 7 and fixedly connected to it; multiple support blades 9 evenly arranged on the support shaft 8 and rotatably connected to it; a fixing mechanism mounted on the support column 3 for fixing it; a fixing groove 10 formed on the support column 3; a fixing column 11 mounted within the fixing groove 10 and slidably connected to it; a fixing plate 12 mounted on the fixing column 11 and fixedly connected to it; a rotating component mounted on the support block 2; and a telescopic mechanism mounted within the support plate 6 for telescopically extending the drive block 7.
[0029] Reference Figure 5 In a preferred embodiment, the rotating component includes: a rotating shaft 13, which is disposed on the support block 2 and rotatably connected to the support block 2; a rotating block 14, which is disposed on the rotating shaft 13 and fixedly connected to the rotating shaft 13; and a sliding component, which is disposed on the support block 2.
[0030] This configuration allows the rotating shaft 13, which is fixedly connected to the rotating block 14, to rotate on the support block 2, thereby driving the sliding component to operate.
[0031] Reference Figure 3 and Figure 5 In a preferred embodiment, the sliding component includes: a sliding groove 15, which is formed on the support block 2; and two sliding blocks 16, which are symmetrically arranged in the sliding groove 15, slidably connected to the sliding groove 15, and threadedly connected to the rotating shaft 13.
[0032] Reference Figure 5 In a preferred embodiment, the sliding block 16 is fixedly connected to the fixed plate 12.
[0033] This configuration causes the sliding block 16, which is threadedly connected to the rotating shaft 13, to rotate, allowing the sliding block 16 to slide within the sliding groove 15. This causes the sliding blocks 16 to move away from each other, moving the fixing plate 12, which is fixedly connected to the sliding block 16, and causing the fixing column 11, which is fixedly connected to the fixing plate 12, to slide away from the support column 3 until the fixing column 11 is completely disengaged from the fixing groove 10, thereby enabling the disassembly of the support column 3.
[0034] Reference Figure 4 In a preferred embodiment, the telescopic mechanism includes: a telescopic shaft 17, which is disposed on the support plate 6 and fixedly connected to the support plate 6; a telescopic block 18, which is fixedly connected to the telescopic shaft 17; and a transmission component disposed within the support plate 6.
[0035] This configuration allows the rotating telescopic block 18 to drive the telescopic shaft 17, which is fixedly connected to the telescopic block 18, to rotate on the support plate 6, thereby driving the transmission components to operate.
[0036] Reference Figure 3 and Figure 4 In a preferred embodiment, the transmission component includes: a transmission groove 19, which is formed on the support plate 6; two transmission blocks 20, which are symmetrically arranged in the transmission groove 19, slidably connected to the transmission groove 19, and threadedly connected to the telescopic shaft 17; and a connecting component, which is disposed on the transmission blocks 20.
[0037] This configuration allows the transmission block 20, which is threadedly connected to the telescopic shaft 17, to slide within the transmission groove 19, causing the transmission blocks 20 to move closer to each other and thus driving the connecting components to operate.
[0038] Reference Figure 4 In a preferred embodiment, the connecting component includes: a first connecting shaft 21, which is disposed on the transmission block 20 and fixedly connected to the transmission block 20; a connecting plate 22, which is rotatably connected to the first connecting shaft 21; a second connecting shaft 23, which is rotatably connected to the connecting plate 22; and a connecting frame 24, which is disposed on the second connecting shaft 23, fixedly connected to the second connecting shaft 23, and fixedly connected to the drive block 7.
[0039] This configuration causes the connecting plate 22, which is rotatably connected to the first connecting shaft 21, to rotate, and causes the connecting frame 24, which is fixedly connected to the second connecting shaft 23, to move, thereby driving the drive block 7, which is fixedly connected to the connecting frame 24, to slide within the support plate 6, thus enabling the extension and retraction of the machine arm.
[0040] Working principle: When in use, use a disassembly tool to rotate the rotating block 14, so that the rotating shaft 13 fixedly connected to the rotating block 14 rotates on the support block 2, thereby driving the sliding block 16 threadedly connected to the rotating shaft 13 to rotate, so that the sliding block 16 slides in the sliding groove 15, causing the sliding blocks 16 to move away from each other, causing the fixing plate 12 fixedly connected to the sliding block 16 to move, and causing the fixing column 11 fixedly connected to the fixing plate 12 to slide away from the support column 3 until the fixing column 11 is completely disengaged from the fixing groove 10, thereby realizing the disassembly of the support column 3;
[0041] Then, rotating the telescopic block 18 causes the telescopic shaft 17, which is fixedly connected to the telescopic block 18, to rotate on the support plate 6. This causes the transmission block 20, which is threadedly connected to the telescopic shaft 17, to slide in the transmission groove 19, causing the transmission blocks 20 to move closer to each other. This causes the connecting plate 22, which is rotatably connected to the first connecting shaft 21, to rotate, causing the connecting frame 24, which is fixedly connected to the second connecting shaft 23, to move. This causes the drive block 7, which is fixedly connected to the connecting frame 24, to slide in the support plate 6, thereby realizing the extension and retraction of the arm.
[0042] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
