Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A telescopic arm for drones.

[0023] The device includes an outer arm tube 110, one end of which is slidably connected to a first inner arm tube 120, and one end of the first inner arm tube 120 is slidably connected to a second inner arm tube 130. A telescopic component for adjusting the length of the arm is installed inside the outer arm tube 110, and a drive component for driving the telescopic component is installed inside the outer arm tube 110. The telescopic component, the first inner arm tube 120, and the second inner arm tube 130 can adjust the length of the UAV arm in multiple stages.

[0024] The telescopic assembly is responsible for adjusting the length of the boom, while the drive assembly provides power to the telescopic assembly. This design not only improves the drone's flexibility and adaptability but also reduces human intervention through automated operation, thus increasing ease of operation and efficiency.

[0025] The telescopic assembly includes a first threaded rod 210. One end of the outer arm tube 110 is provided with a first groove 220 that is slidably connected to the first inner arm tube 120. The first threaded rod 210 is rotatably connected in the first groove 220. The first threaded rod 210 and the first inner arm tube 120 are threadedly connected.

[0026] The telescopic assembly, through the design of the first threaded rod 210 and the first sliding groove 220, enables the telescopic movement of the first inner arm tube 120 within the outer arm tube 110. The rotation of the first threaded rod 210, via a threaded connection, drives the first inner arm tube 120 to slide along the first sliding groove 220, thereby adjusting the arm length. This design not only improves the accuracy of telescopic movement but also ensures stability after telescopic movement through the self-locking property of the threaded connection.

[0027] The telescopic assembly also includes a second threaded rod 230. One end of the first inner arm tube 120 is provided with a second sliding groove 240 that is slidably connected to the second inner arm tube 130. The second threaded rod 230 is rotatably connected in the second sliding groove 240, and the second threaded rod 230 and the second inner arm tube 130 are threadedly connected.

[0028] The telescopic assembly, through the design of the second threaded rod 230 and the second slide groove 240, enables the telescopic movement of the second inner arm tube 130 within the first inner arm tube 120. The rotation of the second threaded rod 230, via a threaded connection, causes the second inner arm tube 130 to slide along the second slide groove 240, further extending or shortening the arm's length. This multi-stage telescopic design not only improves the arm's flexibility but also achieves a wider range of length adjustment through multi-stage adjustment.

[0029] A limiting block 250 is fixedly installed on the inner wall of the second slide groove 240. The limiting block 250 has a threaded hole 251 that is threadedly connected to the first threaded rod 210. A rotating block 260 is rotatably connected to the limiting block 250. The rotating block 260 is fixedly installed at one end of the second threaded rod 230.

[0030] The design of the limiting block 250 and the threaded hole 251 ensures a stable connection between the first threaded rod 210 and the second threaded rod 230. The limiting block 250 is fixed to the inner wall of the second slide groove 240, and the threaded hole 251 is threadedly connected to the first threaded rod 210, ensuring that the rotation of the first threaded rod 210 can drive the second threaded rod 230 to rotate. The rotating block 260 then fixes the second threaded rod 230 to the limiting block 250, ensuring its stability during rotation.

[0031] The second threaded rod 230 has a limiting hole 231 that is slidably connected to the first threaded rod 210. A first limiting plate 232 is installed on the side wall of the limiting hole 231. A first limiting groove 211 that is slidably connected to the first limiting plate 232 is provided on the side wall of the first threaded rod 210.

[0032] The design of the limiting hole 231 and the first limiting plate 232 ensures the stability of the relative position of the first threaded rod 210 and the second threaded rod 230. The first limiting plate 232 installed in the limiting hole 231 is slidably connected to the first limiting groove 211 on the first threaded rod 210, which restricts the radial movement of the second threaded rod 230 on the first threaded rod 210, ensuring the smoothness and accuracy of the extension and retraction process.

[0033] A second limiting plate 221 is installed on the side wall of the first sliding groove 220, and a second limiting groove 121 is slidably connected to the second limiting plate 221 on the outer wall of the first inner arm tube 120.

[0034] A third limiting plate 241 is installed on the side wall of the second slide groove 240, and a third limiting groove 131 is slidably connected to the third limiting plate 241 on the outer wall of the second inner arm tube 130.

[0035] The design of the second limiting plate 221 and the third limiting plate 241 ensures the stability of the first inner arm tube 120 and the second inner arm tube 130 during the sliding process. The second limiting plate 221 is slidably connected to the second limiting groove 121 on the first inner arm tube 120, and the third limiting plate 241 is slidably connected to the third limiting groove 131 on the second inner arm tube 130, restricting the radial movement of the inner arm tube within the groove and ensuring the smoothness and accuracy of the extension and retraction process.

[0036] The drive assembly includes a drive slot 310, which is formed inside the outer arm tube 110. A motor 320 is installed inside the drive slot 310, and the output end of the motor 320 is connected to the first threaded rod 210.

[0037] The drive assembly, through the design of motor 320 and drive slot 310, provides power to the telescopic assembly. Motor 320 is installed inside drive slot 310, and its output end drives the first threaded rod 210 to rotate via a transmission connection, thereby realizing the telescopic movement of the first inner arm tube 120. This design not only improves the automation level of the telescopic operation, but also ensures the smoothness and accuracy of the telescopic process through precise motor control.

[0038] Specifically, the internal electrical connection structure of the motor 320 is well known to those skilled in the art and will not be described in detail here. All electrical components appearing in this application are connected to an external power source during use.

[0039] The circuits, electrical components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this utility model does not involve any improvement to the software.

[0040] The control method described in this application is automatic control via a controller. The controller's control circuit can be easily implemented by those skilled in the art through simple programming, and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
