[0028] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a multi-rotor unmanned aerial vehicle (UAV) arm-fuselage connection component.

[0029] A multi-rotor unmanned aerial vehicle (UAV) arm-fuselage connection assembly includes a body 1 and a support block 2, the support block 2 being fixedly connected to the body 1; it also includes: two support sleeves 3, symmetrically arranged on the support block 2 and fixedly connected to it; a support column 4, disposed within the support sleeves 3 and rotatably connected to them; a support plate 5, disposed on the support column 4 and rotatably connected to it; a support shaft 6, slidably connected to the support plate 5; and multiple support blades 7, evenly arranged on the support shaft 6 and rotatably connected to it. The system includes: a connecting plate 8 (two plates 8 symmetrically arranged on the body 1 and fixedly connected to the body 1); a clamping mechanism on the support column 4 for clamping the support column 4; a clamping groove 9 on the support column 4; two clamping rings 10 symmetrically arranged in the clamping groove 9 and slidably connected to the clamping groove 9; a clamping column 11 on the clamping ring 10 and fixedly connected to the clamping ring 10; a driving component on the support block 2; and a fixing mechanism on the support plate 5 for fixing the support shaft 6.

[0030] Reference Figure 5 In a preferred embodiment, the driving component includes: a driving shaft 12, which is disposed on the support block 2 and fixedly connected to the support block 2; a driving block 13, which is disposed on the driving shaft 12 and fixedly connected to the driving shaft 12; and a sliding component disposed within the support block 2.

[0031] This configuration allows the rotating drive block 13 to rotate the drive shaft 12, which is fixedly connected to the drive block 13, on the support block 2, thereby driving the sliding component to run.

[0032] Reference Figure 3 and Figure 5 In a preferred embodiment, the sliding component includes: a sliding groove 14, which is formed in the support block 2; and two sliding plates 15, which are symmetrically arranged in the sliding groove 14, slidably connected to the sliding groove 14, and threadedly connected to the drive shaft 12.

[0033] Reference Figure 5 In a preferred embodiment, the sliding plate 15 is fixedly connected to the clamping column 11.

[0034] This configuration causes the sliding plate 15, which is threadedly connected to the drive shaft 12, to rotate, thereby causing the sliding plate 15 to slide within the sliding groove 14. This causes the sliding plates 15 to move away from each other, which in turn causes the clamping column 11, which is fixedly connected to the sliding plate 15, to move. This causes the clamping ring 10, which is fixedly connected to the clamping column 11, to slide within the clamping groove 9, thereby causing the clamping rings 10 to move away from each other until the clamping rings 10 are completely disengaged from the clamping groove 9, thus enabling the disassembly of the support column 4.

[0035] Reference Figure 4 In a preferred embodiment, the fixing mechanism includes: a fixing column 16, which is disposed on the support plate 5 and fixedly connected to the support plate 5; a fixing plate 17, which is fixedly connected to the fixing column 16; a fixing ring 18, which is disposed on the fixing column 16 and rotatably connected to the fixing column 16; and a rotating component, which is disposed on the fixing column 16.

[0036] This configuration allows the rotating fixed ring 18 to rotate on the fixed column 16, thereby driving the rotating component to operate.

[0037] Reference Figure 4 In a preferred embodiment, the rotating component includes: a rotating ring 19, which is disposed on the fixed column 16 and fixedly connected to the fixed column 16; a rotating groove 20, which is formed on the rotating ring 19; a rotating column 21, which is disposed in the rotating groove 20, slidably connected to the rotating groove 20, and fixedly connected to the fixed ring 18; and a transmission component, which is disposed in the support plate 5.

[0038] This configuration allows the rotating column 21, which is fixedly connected to the fixed ring 18, to slide within the rotating groove 20 of the rotating ring 19, thereby driving the transmission components to operate.

[0039] Reference Figure 4In a preferred embodiment, the transmission component includes: a transmission groove 22, which is formed in the support plate 5; a transmission block 23, which is disposed in the transmission groove 22, slidably connected to the transmission groove 22, and fixedly connected to the rotating column 21; a transmission plate 24, which is fixedly connected to the transmission block 23; and a fixing groove 25, which is formed on the support shaft 6.

[0040] Reference Figure 4 In a preferred embodiment, the transmission plate 24 is slidably connected to the fixed groove 25.

[0041] This configuration allows the transmission block 23, which is fixedly connected to the rotating column 21, to slide within the transmission groove 22, causing the transmission blocks 23 to move away from each other and drive the transmission plate 24, which is fixedly connected to the transmission block 23, to move until the transmission plate 24 is completely disengaged from the fixed groove 25, thereby enabling the disassembly of the support shaft 6.

[0042] Working principle: When the support column 4 is damaged by a collision during flight, the disassembly tool is used to rotate the drive block 13, which drives the drive shaft 12 fixedly connected to the drive block 13 to rotate on the support block 2. This causes the sliding plate 15 threadedly connected to the drive shaft 12 to rotate, which in turn causes the sliding plate 15 to slide in the sliding groove 14, making the sliding plates 15 move away from each other. This causes the clamping column 11 fixedly connected to the sliding plate 15 to move, which in turn causes the clamping ring 10 fixedly connected to the clamping column 11 to slide in the clamping groove 9, making the clamping rings 10 move away from each other until the clamping rings 10 are completely disengaged from the clamping groove 9, thereby disassembling the support column 4.

[0043] Next, rotate the fixed ring 18, causing it to rotate on the fixed column 16. This causes the rotating column 21, which is fixedly connected to the fixed ring 18, to slide in the rotating groove 20 of the rotating ring 19. This causes the transmission block 23, which is fixedly connected to the rotating column 21, to slide in the transmission groove 22. This causes the transmission blocks 23 to move away from each other, and causes the transmission plate 24, which is fixedly connected to the transmission block 23, to move until the transmission plate 24 is completely disengaged from the fixed groove 25, thereby disassembling the support shaft 6.

[0044] 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.
