[0025] Reference Figure 1 , Figure 2 The first aspect of this application provides a wire guide mechanism, including a guide rod 100, a mounting assembly 200, and a wire guide 300. The mounting assembly 200 is slidably connected to the guide rod 100 and is provided with a first wire guide hole 210. The wire guide 300 is rotatably connected to the mounting assembly 200 and is provided with a second wire guide hole 310 and a wire guide wheel 320. A cable passes through the first wire guide hole 210 and the second wire guide hole 310 and is connected to the wire guide wheel 320. The wire guide wheel 320 is used to reduce cable wear. The wire guide 300 can rotate around its central axis to adjust the cable exit direction.

[0026] Specifically, the mounting component 200 is slidably connected to the guide rod 100, allowing the mounting component 200 to drive the cable guide 300 to move axially along the guide rod 100, thereby adjusting the cable exit position. Simultaneously, the cable guide 300 is rotatably connected to the mounting component 200, allowing it to rotate around its central axis. In conjunction with the second cable guide hole 310 and cable guide wheel 320 on the cable guide 300, the cable exit direction can be adjusted. The mounting component 200 and guide rod 100 of this application are slidably connected, and the cable guide 300 rotates around its own central axis, enabling the cable guide mechanism to adapt to dynamic changes in cable pulling direction. This allows for real-time adjustment of the cable guide 300's attitude and exit direction, reducing unintended contact and friction between the cable and adjacent components, lessening wear on the cable surface, extending cable lifespan, and improving the operational reliability and safety of the UAV tethering system.

[0027] Reference Figure 2 In some embodiments, the guide rod 100 is arranged along the X-axis direction, and the mounting component 200 is sleeved on the outside of the guide rod 100. During the process of the drone pulling the cable, the mounting component 200 can adaptively slide along the X-axis direction with the cable pulling force, thereby driving the connected wire component 300 to adjust its position synchronously, realizing the dynamic adjustment of the cable outlet position along the X-axis direction, and reducing the phenomenon of excessive pulling or slack when the drone pulls the cable.

[0028] Reference Figure 2 , Figure 3 In some embodiments, the mounting assembly 200 includes a first mounting member 220 and a second mounting member 230. The first mounting member 220 is slidably connected to the guide rod 100 and is sleeved on the outside of the second mounting member 230. The second mounting member 230 is connected to the wire member 300 and can rotate about its central axis to drive the wire member 300 to rotate. A first wire hole 210 is provided in the second mounting member 230. The first mounting component 220 is slidably connected to the guide rod 100. The first mounting component 220 can change position as the drone pulls the cable, causing the entire mounting assembly 200 and the guide wire 300 to adaptively adjust their positions along the guide rod 100. This ensures the cable exit position can adapt to the drone's displacement requirements in the axial direction of the guide rod 100, preventing excessive pulling or slack in the cable due to a fixed exit position. Simultaneously, the first mounting component 220 is sleeved on the outside of the second mounting component 230, and the second mounting component 230 can rotate around its own central axis. This allows the second mounting component 230 to drive the guide wire 300 to rotate synchronously, thereby adjusting the cable exit direction through the rotation of the guide wire 300, adapting to the dynamic guidance requirements when the drone pulls the cable from different directions. Furthermore, the first guide wire hole 210 is located in the second mounting component 230, allowing the cable to adjust its guiding angle synchronously with the rotation of the second mounting component 230 when passing through the first guide wire hole 210, reducing frictional loss between the cable and adjacent components and improving the cable's service life.

[0029] Reference Figures 2 to 4 In some embodiments, the second mounting member 230 includes a first element 231 and a second element 232. The first element 231 is sleeved on the outside of the second element 232, and the second element 232 is rotatably connected to the first element 231. The first mounting member 220 is connected to the first element 231, and the wire member 300 is connected to the second element 232. The first element 231 is sleeved on the outside of the second element 232, and the two form a rotatable engagement, allowing the second element 232 to rotate relative to the first element 231, which facilitates the rotation of the wire member 300. At the same time, the first mounting member 220 is connected to the first element 231, and the sliding of the first mounting member 220 along the guide rod 100 drives the first element 231, the second element 232, and the wire member 300 to synchronously adjust their positions, ensuring that the position adjustment of the wire member 300 in the axial direction of the guide rod 100 is consistent with the overall movement of the mounting assembly 200. In addition, the wire guide 300 is connected to the second element 232, so that the rotational motion of the second element 232 relative to the first element 231 is transmitted to the wire guide 300, causing the wire guide 300 to adjust the outgoing direction of the cable, adapting to the dynamic pulling direction change when the drone pulls the cable.

[0030] Reference Figures 4 to 6In some embodiments, a first ball bearing (not shown in the figure) is provided between the first element 231 and the second element 232, which can convert the sliding friction between the first element 231 and the second element 232 into rolling friction, reduce the frictional resistance during their relative rotation, make the rotation of the second element 232 relative to the first element 231 smoother, reduce the rotational jamming or adjustment lag caused by excessive frictional resistance, ensure that the second element 232 can respond to the change in cable pulling direction and drive the conductor 300 to adjust the cable output direction in time, and improve the adaptive adjustment efficiency of the conductor mechanism for the dynamic pulling direction of the cable.

[0031] Reference Figures 3 to 7 In some embodiments, the conductor 300 includes a head 330 with a mounting cavity 331 communicating with a second conductor hole 310. At least a portion of the second element 232 is disposed within the mounting cavity 331, thereby assembling the conductor 300 with the second mounting element 230. Simultaneously, the communication between the mounting cavity 331 and the second conductor hole 310 reduces bending or jamming of the cable during its path, reduces frictional contact between the cable and the inner wall of the conductor 300, and ensures smooth cable transmission.

[0032] Reference Figures 3 to 7 In some embodiments, the head 330 is provided with a first connecting hole 332, and the second element 232 is provided with a second connecting hole 2321. The first connector 400 passes through the first connecting hole 332 and engages with the second connecting hole 2321, thereby connecting the head 330 and the second element 232. This allows the rotational motion of the second element 232 to be synchronously transmitted to the head 330 and the entire conductor 300, avoiding power transmission lag or deviation caused by loose connection, ensuring the accuracy of the lead wire 300's cable exit direction adjustment, and thus adapting to the dynamic changes in cable pulling direction during cable take-up. Furthermore, the first connector 400 can be a headless screw to prevent it from being exposed inside the second conductor hole 310, preventing friction between the cable and the first connector 400 during take-up, release, or guidance, further reducing the risk of cable surface wear and ensuring the smoothness of the cable transmission path. Of course, in actual design, the structure of the first connector 400 can be designed according to actual needs.

[0033] Reference Figures 3 to 7In some embodiments, the cable guide 300 further includes a tail section 340 connected to the head section 330. A cable guide wheel 320 is rotatably connected to the tail section 340. This converts the sliding friction between the cable and the cable guide 300 into rolling friction on the cable guide wheel 320, reducing frictional resistance during cable deployment and retraction, minimizing wear on the cable surface caused by friction, preventing premature damage to the cable insulation or internal core wires, and extending the cable's lifespan. Furthermore, the cable guide wheel 320 rotates synchronously with the cable, ensuring the consistency and smoothness of the cable deployment path and reducing the risk of signal interruption or unstable power transmission in the UAV tethered system due to abnormal cable transmission.

[0034] Reference Figure 6 , Figure 7 In some embodiments, the tail portion 340 includes two conductor blocks 341 symmetrically arranged along the central axis of the conductor member 300 to form a second conductor hole 310. At least two conductor wheels 320 are disposed in the second conductor hole 310, spaced apart, so that the cable exits between the two conductor wheels 320. Specifically, by setting two conductor blocks 341 symmetrically arranged along the central axis of the conductor member 300 to form the second conductor hole 310, the tail portion 340 can ensure that the cable remains near the central axis of the conductor member 300 when passing through the second conductor hole 310. At the same time, the symmetrical design makes the diameter of the second conductor hole 310 more compatible with the cable, reducing the risk of jamming during cable passage and ensuring the stability of the cable transmission path. In addition, the two conductor wheels 320 are spaced apart in the second conductor hole 310, and the cable exits between the two conductor wheels 320, so that the cable can simultaneously form rolling contact with the conductor wheels 320 when passing through the second conductor hole 310, thereby reducing cable wear.

[0035] Reference Figures 3 to 5In some embodiments, the first mounting member 220 includes a base 221 and an extension 222 connected to the base 221. The base 221 is sleeved on the outside of the second mounting member 230, and the extension 222 is slidably connected to the guide rod 100. Specifically, the base 221 sleeved on the outside of the second mounting member 230 can form a wrapping limit on the second mounting member 230, ensuring that the second mounting member 230 always maintains axial alignment during rotation, avoiding offset or shaking, ensuring the accuracy of the rotation adjustment of the guide member 300 driven by the second mounting member 230, and enhancing the compactness of the connection between the first mounting member 220 and the second mounting member 230, reducing the space occupied by the overall structure, and avoiding adjustment jamming caused by loose component connections. In addition, the extension 222 is connected to the base 221 and slidably connected to the guide rod 100, so that the extension 222 can drive the base 221, the second mounting member 230 and the wire member 300 to move along the guide rod 100, ensuring that the mounting assembly 200 can adaptively adjust its axial position as the position changes when the UAV pulls the cable, adapting to the cable's winding and unwinding requirements in the axial direction of the guide rod 100, and avoiding excessive pulling or slack of the cable due to the fixed exit position.

[0036] Reference Figures 3 to 5 In some embodiments, two extensions 222 and two guide rods 100 are provided. The two extensions 222 are symmetrically arranged along the central axis of the first mounting member 220. Each extension 222 is slidably connected to the corresponding guide rod 100. This reduces the offset and shaking of the first mounting member 220 due to unilateral force or unilateral guidance during the axial sliding of the first mounting member 220 along the guide rod 100, ensuring that the first mounting member 220 always slides in a preset direction. This, in turn, drives the mounting assembly 200 and the wire member 300 to adjust their positions, ensuring the accuracy of the cable outlet position adjustment and adapting to the dynamic position changes when the drone pulls the cable. At the same time, the symmetrical cooperation between the two extensions 222 and the two guide rods 100 can evenly distribute the weight of the first mounting member 220 and its connected components, the cable tension, and other forces to the two guide rods 100. This avoids increased wear or structural deformation of a single guide rod 100 due to concentrated force, extends the service life of the guide rod 100 and the extension 222, and improves the structural load-bearing capacity and long-term operational reliability of the wire mechanism.

[0037] Reference Figure 3In some embodiments, a guide sleeve 223 is provided between the extension 222 and the guide rod 100. The guide sleeve 223 is sleeved on the outside of the guide rod 100. The guide sleeve 223 is provided with a plurality of mounting holes, and a second ball bearing 224 is rotatably installed in each of the plurality of mounting holes. This can convert the original sliding friction between the extension 222 and the guide rod 100 into the rolling friction of the second ball bearing 224, reduce the frictional resistance during the relative sliding process between the extension 222 and the guide rod 100, make the sliding action of the extension 222 along the guide rod 100 smoother, reduce the sliding jamming or adjustment lag caused by excessive frictional resistance, and ensure that the mounting component 200 can respond to the positional changes when the UAV pulls the cable and adjust the axial position in a timely manner to adapt to the cable exit requirements.

[0038] Reference Figure 3 In some embodiments, the extension 222 is provided with a mounting groove 2221, and the guide sleeve 223 is disposed in the mounting groove 2221 to ensure that the guide sleeve 223 always maintains the preset installation position during the sliding of the extension 222 along the guide rod 100, so as to avoid the guide sleeve 223 from shifting or falling off due to vibration, friction and other factors, and to ensure the stability of the coordinated action of the guide sleeve 223 and the second ball 224, thereby maintaining the smoothness of the sliding action of the extension 222.

[0039] Reference Figure 3 In some embodiments, the first mounting member 220 further includes a cover plate 225, which covers the mounting groove 2221 and is detachably connected to the extension 222. The cover plate 225 can protect the guide sleeve 223 and the second ball 224 in the mounting groove 2221, preventing external dust, moisture, impurities, etc. from entering the interior of the mounting groove 2221, avoiding contaminants adhering to the surface of the guide sleeve 223 or the second ball 224 and affecting the rolling performance, reducing component wear, and extending the service life of the guide sleeve 223 and the second ball 224.

[0040] Reference Figure 3 In some embodiments, the cover plate 225 is provided with a third connecting hole 2251, and the extension 222 is provided with a fourth connecting hole 2222. The second connector 500 passes through the third connecting hole 2251 and engages with the fourth connecting hole 2222 to connect the cover plate 225 and the extension 222, thereby installing the guide sleeve 223 in the mounting groove 2221. This provides axial limiting for the guide sleeve 223, preventing it from slipping out of the mounting groove 2221 when the extension 222 slides along the guide rod 100 or is affected by external vibrations, ensuring that the guide sleeve 223 is always in the preset working position. Furthermore, the second connector 500 is a screw. Of course, the cover plate 225 and the extension 222 can also be designed to be plugged in or snapped together. In actual design, the detachable connection method between the cover plate 225 and the extension 222 can be designed according to actual needs.

[0041] A second aspect of this application provides a drone, including the cable guide mechanism of the first aspect of this application. By providing the cable guide mechanism, it is possible to ensure that the ground-end cable can adaptively guide and extend / retract according to the dynamic changes in the drone's position and attitude during takeoff, landing, and aerial tethering operations. Furthermore, the sliding and rotational degrees of freedom of the cable guide mechanism allow the cable's outgoing direction to match the changes in pull direction caused by the drone's movement in real time, reducing unexpected contact and friction between the cable and adjacent components, and extending the cable's service life.

[0042] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
