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 scope of protection of this utility model.

[0057] The terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0060] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0061] The following is combined Figures 1 to 9 This invention describes a tethered drone cable reeling and deployment device and a tethered drone.

[0062] like Figures 1 to 7 As shown, a specific embodiment of the first aspect of this utility model provides a tethered drone cable deployment and retrieval device. The tethered drone cable deployment and retrieval device includes a cable deployment and retrieval component 100, a drive component 200, and a first locking component 300; the drive component 200 is connected to the cable deployment and retrieval component 100 and is used to drive the cable deployment and retrieval component 100 to move, thereby deploying and retrieving the cable; the first locking component 300 has a first position and a second position; in the first position, the first locking component 300 locks the cable; in the second position, the first locking component 300 releases the cable.

[0063] In this embodiment, the cable reeling and deployment movement is directly controlled by the drive component 200, enabling precise adjustment of the cable length to adapt to the needs of the drone at different altitudes or positions, and improving operational response speed. After cable reeling and deployment are completed, the first locking component 300 can switch from the second position to the first position to lock the cable, preventing accidental slippage and avoiding loosening during transport. This solves the problem of cable loosening frequently occurring during transport in existing tethered drone cable reeling and deployment devices. When the cable is needed, the first locking component 300 can switch from the first position to the second position to release the cable, ensuring smooth cable reeling and deployment operations.

[0064] like Figure 1 and Figure 2 As shown, the tethered UAV cable retraction and deployment device further includes a housing 400; the housing 400 has a mounting cavity; the cable retraction and deployment component 100, the drive component 200, and the first locking component 300 are all located in the mounting cavity. By providing the housing 400, the cable retraction and deployment component 100, the drive component 200, and the first locking component 300 are integrated within the housing 400, facilitating transportation. The design of the housing 400 also protects the cable retraction and deployment component 100, the drive component 200, and the first locking component 300.

[0065] like Figure 2 As shown, optionally, one side of the housing 400 has an operating port; a switch door 410 is installed at the operating port. By opening or closing the switch door 410, the first locking component 300 can be manually operated to switch between a first position and a second position.

[0066] like Figure 2 As shown, optionally, heat dissipation holes are provided on the housing 400.

[0067] like Figure 2 As shown, optionally, the side of the housing 400 also has an electrical interface 420. One side of the electrical interface 420 is used to connect to an external power source; the other side of the electrical interface 420 can also be electrically connected to one end of a cable. The cable located inside the housing 400 is wound by the cable reeling component 100, and the other end of the cable passes through the operating port and is electrically connected to the drone body located outside the housing 400, realizing power supply and communication for the drone body.

[0068] Specifically, the upper side of the housing 400 has an operating port.

[0069] like Figure 2 As shown, optionally, the left and right sides of the housing 400 are provided with handling handles 430; the handling handles 430 facilitate the handling of the whole machine.

[0070] like Figure 2 and Figure 3As shown, in some embodiments, the cable winding and unwinding component 100 includes a winch 110 and a cable routing assembly 120; along the axial direction of the cable, the cable routing assembly 120 has a cable passage hole, and a cable is disposed in the cable passage hole; the first end of the driving component 200 is connected to the winch 110 and is used to drive the winch 110 to rotate around its own axis; the second end of the driving component 200 is connected to the cable routing assembly 120 and is used to drive the cable routing assembly 120 to reciprocate along the axial direction of the winch 110, in coordination with the winch 110 to wind up and unwind the cable.

[0071] In this embodiment, the drive component 200 directly drives the winch 110 to rotate, enabling rapid cable winding and unwinding, ensuring the cable is tightly wound on the winch 110 and preventing loosening. The reciprocating motion of the cable guide assembly 120 (along the axis of the winch 110) ensures the cable is evenly distributed on the surface of the winch 110, avoiding local accumulation or cross-entanglement, and reducing damage to the cable caused by friction and compression. The cable through-hole constrains the cable's entry and exit path, ensuring the cable always moves along a predetermined path. The drive component 200 simultaneously controls the rotation of the winch 110 (winding and unwinding action) and the movement of the cable guide assembly 120 (guiding action), and their speeds can be dynamically matched (e.g., the rotation speed of the winch 110 is proportional to the cable movement speed), achieving synchronous winding and unwinding and preventing cable jamming or loosening. When the UAV is rapidly ascending, descending, or moving, the linkage between the winch 110 and the cable guide assembly 120 can quickly respond to changes in cable tension, keeping the cable taut and neatly arranged.

[0072] Specifically, the winch 110 and the cable assembly 120 are both located within the mounting cavity of the housing 400; the winch 110 is fitted to the housing 400, and the cable assembly 120 can reciprocate relative to the housing 400 along the axis of the winch 110. The first end of the drive component 200 drives the winch 110 to rotate relative to the housing 400, and the second end of the drive component 200 drives the cable assembly 120 to reciprocate relative to the housing 400 along the axis of the winch 110. This design allows the cable to be wound around the winch 110 and arranged reciprocally along the axis of the winch 110.

[0073] like Figure 2 and Figure 3As shown, the take-up and release component 100 further includes a first transmission assembly 130; one end of the first transmission assembly 130 is connected to the second end of the drive component 200, and the other end of the first transmission assembly 130 is connected to the cable laying assembly 120; the second end of the drive component 200 drives one end of the first transmission assembly 130 to rotate, and the other end of the first transmission assembly 130 drives the cable laying assembly 120 to reciprocate along the axis of the winch 110. The drive component 200 distributes power to the cable laying assembly 120 through the first transmission assembly 130, ensuring coordinated and synchronized movement of the winch 110 (take-up and release) and the cable laying (guiding), avoiding cable accumulation or misalignment due to insufficient power or delay. The first transmission assembly 130 can convert the rotational motion of the drive component 200 into the linear reciprocating motion of the cable laying assembly 120, improving cable laying accuracy and adapting to different winch 110 widths and cable specifications.

[0074] like Figure 3 As shown, optionally, the first transmission assembly 130 is a lead screw and nut structure. The first transmission assembly 130 includes a lead screw 131, a limiting rod 132, and a fixing block 133; one end of the lead screw 131 is connected to the second end of the drive component 200, and the other end extends along the axis of the winch 110 and is rotatably assembled with the housing 400; the axis of the limiting rod 132 is parallel to the axis of the winch 110, and both ends of the limiting rod 132 are connected to the two sides of the housing 400; the fixing block 133 is threadedly assembled with the lead screw 131 and slidably engaged with the limiting rod 132 along the axis of the winch 110; the fixing block 133 is also connected to the cable laying assembly 120. When the second end of the drive component 200 drives the lead screw to rotate in the forward direction, the fixing block 133 carries the cable laying assembly 120 to move to the left along the axis of the winch 110; when the second end of the drive component 200 drives the lead screw to rotate in the reverse direction, the fixing block 133 carries the cable laying assembly 120 to move to the right along the axis of the winch 110. By adjusting the rotation direction of the lead screw 131, the cable assembly 120 can reciprocate along the axis of the winch 110.

[0075] like Figure 5 As shown, the winch 110 further includes two mounting plates 111, two support plates 112, a connecting sleeve 113, and multiple connecting rods 114. The two mounting plates 111 are spaced apart along their own axes. The two support plates 112 are located between the two mounting plates 111 and are coaxially arranged with the mounting plates 111, with the two support plates 112 spaced apart. The multiple connecting rods 114 are spaced apart around the circumference of the support plates 112 and are connected to the sides of the support plates 112. The two ends of the connecting rods 114 are respectively connected to the two mounting plates 111. The two ends of the connecting sleeve 113 are respectively fitted onto the two support plates 112 and are coaxially arranged with the two support plates 112. The connecting sleeve 113 has a cable passage hole for the cable to pass through.

[0076] Optionally, the mounting plate 111 can be at least one of a circle, an ellipse, or a polygon. In this embodiment, the shape of the mounting plate 111 is not limited. Preferably, the mounting plate 111 is circular, which makes the whole machine more aesthetically pleasing.

[0077] Optionally, the support plate 112 can be at least one of a circle, an ellipse, or a polygon. In this embodiment, the shape of the support plate 112 is not limited. Preferably, the support plate 112 is circular, which makes the whole machine more aesthetically pleasing.

[0078] Optionally, the diameter of the mounting plate 111 is larger than the diameter of the support plate 112. The support plate 112 supports the connecting rod 114, while the mounting plate 111 secures the multiple connecting rods 114. Additionally, the mounting plate 111 also secures the winch 110 to the housing 400.

[0079] Optionally, the mounting plate 111 has multiple positioning holes 101; the multiple positioning holes 101 are arranged at intervals around the axis of the mounting plate 111. When one end of the second locking component is inserted into a positioning hole 101, it locks the winch 110; when the other end of the second locking component is pulled out of the positioning hole 101, it unlocks the winch 110.

[0080] like Figure 6 As shown, the cable assembly 120 further includes a cable mounting component 121 and a guide structure 122. The cable mounting component 121 has a cable passage hole. The cable mounting component 121 is connected to the second end of the drive component 200. The guide structure 122 includes two guide pulleys. Along the radial direction of the cable, the two guide pulleys are located on both sides of the cable and are in contact with the cable. The two guide pulleys contact the cable from both sides and cooperate with the cable passage hole to form a stable positioning, ensuring that the cable always moves along the predetermined path and avoiding lateral deviation or swinging during the winding and unwinding process. The cable passage hole limits the cable, allowing the cable to move along the predetermined route. The guide structure 122 further guides the cable, ensuring smooth cable movement. If the cable is slightly deflected due to external forces (such as wind), the pulleys can automatically adjust their position through rolling friction to prevent the cable from hard friction with the edge of the cable passage hole, thus extending the cable's lifespan.

[0081] Specifically, the cable mounting component 121 is mounted on the fixing block 133 of the first transmission assembly 130; along the axial direction of the winch 110, the fixing block 133 has a threaded hole and a limiting hole; a limiting rod 132 is slidably mounted in the limiting hole, and the threaded hole is threadedly assembled with the lead screw 131. The first locking component 300 is mounted on the cable mounting component 121.

[0082] Optionally, the cable assembly 120 is positioned near the operating port of the housing 400. In other words, the first locking component 300 is preferably positioned near the operating port of the housing 400 to lock the cable exiting the housing and prevent the cable from becoming loose during handling.

[0083] Specifically, an operation port is provided on the upper side of the housing 400, and the first transmission assembly 130 and the cable assembly 120 are located above the winch 110 along the radial direction of the winch 110.

[0084] Optionally, the number of guide structures 122 is at least two; the two guide structures 122 are arranged at intervals along the axial direction of the cable, and the two locking members 311 of the first locking member 300 can be located between the two guide structures 122. Multiple guide structures 122 can further guide the cable, ensuring that the cable can move along a predetermined route.

[0085] like Figure 6 As shown, the cable mounting component 121 further includes a mounting plate 1211 and a guide limiting rod 1212; the guide limiting rod 1212 is arranged at intervals with the mounting plate 1211; one end of the guide limiting rod 1212 is connected to one end of the side of the mounting plate 1211, and the other end is connected to the other end of the side of the mounting plate 1211, so that a cable passage hole is formed between the guide limiting rod 1212 and the side of the mounting plate 1211.

[0086] like Figure 4 As shown, the drive component 200 further includes a first drive assembly 210, a rotating shaft, a second transmission assembly 220, a third transmission assembly 230, and a connecting shaft 240. A wire passage is formed within the rotating shaft, which communicates with a wire hole on the connecting sleeve 113. The rotating shaft is fixedly installed within the connecting sleeve 113 of the winch 110, and one end of the rotating shaft is connected to the first drive assembly 210 via a bearing; one end of the second transmission assembly 220 is fixedly installed on the rotating shaft and rotates synchronously with it; the other end of the rotating shaft also rotates in cooperation with a photoelectric slip ring. A cable is provided within the photoelectric slip ring, one end of which is used to connect to an external power source, and the other end passes through the photoelectric slip ring, the wire passage of the rotating shaft, and the wire hole of the connecting sleeve 113 before being wound around the connecting rod 114 of the winch 110.

[0087] One end of the second transmission assembly 220 is mounted on a bearing, and the other end is mounted on one end of the connecting shaft 240. One end of the third transmission assembly 230 is mounted on the other end of the connecting shaft 240, and the other end is connected to one end of the lead screw 131. The first drive assembly 210 drives the rotating shaft to rotate, which in turn drives the winch 110 to rotate. The rotating shaft also drives the lead screw 131 of the first transmission assembly 130 to rotate through the second transmission assembly 220 and the third transmission assembly 230, thereby causing the cable laying assembly 120 to move along the axis of the winch 110. The first drive assembly 210 can adjust the rotation direction to change the rotation direction of the winch 110 and the movement direction of the cable laying assembly 120, so that the cable is wound around the connecting rod 114 of the winch 110 along the axis of the winch 110.

[0088] In this embodiment, a single first drive component 210 can synchronously drive the winch 110 to rotate and the cable laying assembly 120 to move linearly via a rotating shaft and second / third transmission components 230, reducing the complexity and energy consumption of multi-motor control. The winding and unwinding speeds of the winch 110 and the moving speed of the cable laying assembly 120 are coupled through the transmission components, avoiding cable accumulation or pulling caused by electronic control delays. The photoelectric slip ring allows the cable to remain powered / communicating while the shaft rotates, while preventing the cable from tangling. The rotating shaft serves as both the power transmission core and the cable channel, eliminating the need for an additional cable guiding structure 122 and reducing space occupation.

[0089] Optionally, the first drive assembly 210 includes, but is not limited to, a joint motor. The joint motor is connected to one end of the rotating shaft via a bushing and is used to drive the rotating shaft to rotate. The rotating shaft is fixedly mounted on the connecting sleeve 113, so the rotating shaft can drive the connecting sleeve 113 to rotate synchronously; at the same time, it can also drive the photoelectric slip ring to rotate synchronously.

[0090] like Figure 4As shown, optionally, the second transmission assembly 220 includes a pulley transmission structure; the pulley transmission structure includes a second driving pulley, a second transmission belt, and a second driven pulley; the second driving pulley is mounted on a rotating shaft, the other end of which is connected to an optoelectronic slip ring; the second driven pulley is mounted on one end of a connecting shaft 240; the other end of the connecting shaft 240 extends along the axis of the winch 110 and is connected to one end of the third transmission assembly 230. The second transmission belt is sleeved on the second driving pulley and the second driven pulley. The rotating shaft drives the second driving pulley to rotate, and the second driving pulley drives the second driven pulley and the connecting shaft 240 to rotate synchronously via the second transmission belt; when the connecting shaft 240 rotates, it also drives one end of the third transmission assembly 230 to rotate synchronously. When the second driving pulley rotates, it also drives the optoelectronic slip ring to rotate. One end of the cable is connected to an external power source, and the other end passes through the optoelectronic slip ring, the cable passage on the rotating shaft, and the cable hole on the connecting sleeve 113, and then winds around the connecting rod 114 of the winch 110. Finally, after passing through the cable assembly 120, it connects to the external UAV body through the operating port. Cables can be wound up and unwound by rotating the winch 110 in both directions.

[0091] like Figure 4 As shown, optionally, the third transmission assembly 230 can have the same structure as the second transmission assembly 220. Specifically, the third transmission assembly 230 includes a third driving wheel 231, a third transmission belt 232, and a third driven wheel 233. The third driving wheel 231 is mounted on the connecting shaft 240; the third driven wheel 233 is mounted on one end of the lead screw 131; the third transmission belt 232 is sleeved on the third driving wheel 231 and the third driven wheel 233. The connecting shaft 240 drives the third driving wheel 231 to rotate synchronously, the third driving wheel 231 drives the third driven wheel 233 to rotate through the third transmission belt 232, the third driven wheel 233 drives the lead screw 131 to rotate, and the lead screw 131 drives the cable assembly 120 to move along the axial direction of the winch 110.

[0092] like Figure 3 and Figure 4 As shown, the tethered drone cable deployment and retrieval device further includes a drive handle 500; the other end of the connecting shaft 240 extends to the outside of the housing 400; the drive handle 500 is connected to the other end of the connecting shaft 240. When the first drive assembly 210 is not working, for example, when the first drive assembly 210 is without power, the operator can drive the third transmission assembly 230 to rotate via the drive handle 500, and the third transmission assembly 230 can drive the cable assembly 120 to move via the lead screw 131; at the same time, the drive handle 500 can also drive the second transmission assembly 220 to rotate via the connecting shaft 240, thereby driving the winch 110 to rotate synchronously.

[0093] Optionally, the drive handle 500 can be detachably connected to the other end of the connecting shaft 240.

[0094] like Figure 6 and Figure 7 As shown, in some embodiments, the first locking component 300 includes a cable locking assembly 310 and a cable driving assembly 320; the cable locking assembly 310 is mounted on the ribbon cable assembly 120; the cable locking assembly 310 has a first position and a second position; the cable driving assembly 320 is connected to the cable locking assembly 310 and is used to drive the cable locking assembly 310 to switch between the first position and the second position. Specifically, both the cable locking assembly 310 and the cable driving assembly 320 are mounted on the mounting plate 1211 of the ribbon cable assembly 120.

[0095] In this embodiment, the cable locking component 310 is installed on the cable assembly 120, which makes full use of the installation space on the cable assembly 120 and facilitates the locking of the cable, thus solving the problem of the cable on the winch 110 becoming loose during transportation.

[0096] Furthermore, the first locking component 300 also includes a limiting component; the cable drive component 320 is limited and engaged with the cable assembly 120 through the limiting component. The limiting component can lock the cable drive component 320 in the first position, preventing the cable locking component 310 from automatically switching from the first position to the second position during transportation.

[0097] Optionally, the limiting component includes a spring pin; the cable assembly 120 has a limiting groove; in the first position, the spring pin springs into the limiting groove to lock the cable locking assembly 310 in the first position. Under the action of external force, such as manual operation of the cable drive assembly 320, the spring pin slides out of the limiting groove. At this time, the cable locking assembly 310 switches from the first position to the second position, releasing the locking of the cable.

[0098] like Figure 6 and Figure 7 As shown, the cable locking assembly 310 further includes two locking members 311; both locking members 311 are rotatably mounted on the cable assembly 120; along the radial direction of the cable, the two locking members 311 are located on both sides of the cable; in a first position, the two locking members 311 clamp the cable; in a second position, the two locking members 311 release the cable; the driving end of the cable driving assembly 320 is hinged to the two locking members 311 through a first rotating shaft, for driving the two locking members 311 to rotate in opposite directions to clamp the cable.

[0099] In this embodiment, two locking members 311 are positioned on either side of the cable and clamp together by rotating in opposite directions, which can evenly distribute the clamping force and avoid cable skewing or localized squeezing damage caused by pressure on one side. The hinged design allows the locking members 311 to automatically adjust their angle under the action of the drive assembly to adapt to cables of different diameters, ensuring that the clamping surface is fully in contact with the cable surface and improving locking stability.

[0100] Optionally, the cable drive assembly 320 includes an operating lever; the lower end of the operating lever is hinged to two locking members 311 via a first pivot; when the operating lever moves downward along its own axis, the operating lever drives the two locking members 311 to rotate in opposite directions to clamp the cable. Simultaneously, a spring pin on the operating lever slides into a limiting groove to limit the operating lever to a first position. When the operating lever is pulled upward, the spring pin slides out of the limiting groove, and the operating lever drives the two locking members 311 to rotate in opposite directions to release the cable.

[0101] Optionally, the locking component 311 includes a locking linkage and a locking block; the locking block is mounted on the locking linkage and is located between the two ends of the locking linkage; one end of the locking linkage is rotatably mounted on the mounting plate 1211 of the cable assembly 120, and the other end is rotatably engaged with the lower end of the operating lever via a first rotating shaft; the upper end of the operating lever faces the operating port of the housing 400. In use, the operator presses the operating lever down from the operating port, the operating lever drives the two locking linkages to rotate, and the two locking linkages drive the two locking blocks to move towards each other to clamp the cable.

[0102] Optionally, the locking link is rotatably mounted on the mounting plate 1211 via a damping shaft. The damping shaft can fix the cable locking assembly 310 in a first position or a second position.

[0103] like Figure 8 and Figure 9 As shown, in some embodiments, the tethered drone cable reeling and deployment device further includes a second locking component 600, a locking detection component 700, and a control component; the second locking component 600 has a third position and a fourth position; in the third position, the second locking component 600 locks the cable reeling and deployment component 100; in the fourth position, the second locking component 600 releases the cable reeling and deployment component 100; the locking detection component 700 is used to detect that the cable reeling and deployment component 100 is in a locked state; the control module is electrically connected to the locking detection component 700 and the drive component 200; in the third position, the control module outputs a first control command to control the drive component 200 to maintain a stopped state; in the fourth position, the control module outputs a second control command to control the drive component 200 to start. In this embodiment, by setting the second locking component 600, the take-up and unwinding component 100 can be mechanically locked; by setting the locking detection component 700 and the control component, it can be ensured that the drive component 200 will only start when the take-up and unwinding component 100 is unlocked, thus avoiding the drive component 200 from starting when the take-up and unwinding component 100 is locked, thereby achieving soft protection for the take-up and unwinding component 100 and reducing the risk of damage to the entire box.

[0104] Furthermore, the second locking component 600 includes a locking assembly 610; the locking assembly 610 is rotatably mounted on the housing 400; one end of the locking assembly 610 extends into the housing 400 and is connected to or separated from the take-up / delivery component 100. Specifically, one end of the locking assembly 610 is inserted into the positioning hole 101 of the mounting plate 111 to lock the take-up / delivery component 100; the other end of the locking assembly 610 is separated from the positioning hole 101 of the mounting plate 111 to unlock the take-up / delivery component 100. The other end of the locking assembly 610 is located on the outside of the housing 400 for easy operation by the operator.

[0105] Optionally, the second locking component 600 further includes a mounting bracket 620; the mounting bracket 620 has an installation space; the mounting bracket 620 is installed in the mounting cavity of the housing 400; the locking assembly 610 is threaded onto the mounting bracket 620; and the locking detection component 700 is located within the installation space. The mounting bracket 620 serves to protect the locking detection component 700 and also provides a mounting base for the locking detection component 700.

[0106] Optionally, the locking assembly 610 includes, but is not limited to, a self-locking elastic pin; the self-locking elastic pin is threaded onto the mounting bracket 620, and one end of the self-locking elastic pin passes through a side wall of the mounting bracket 620 and connects or separates from the positioning hole 101 of the mounting plate 111; the other end of the self-locking elastic pin passes through the housing 400 and extends to the outside of the housing 400, which is convenient for the operator to operate. The operator can lock and unlock the take-up and undo component 100 by rotating the self-locking elastic pin.

[0107] like Figure 8 and Figure 9 As shown, the locking detection component 700 further includes a light source, a photoelectric element 710, and a grating 720. The light source emits a light beam; the photoelectric element 710 is arranged at a distance from the light source to receive the light beam; the photoelectric element 710 is electrically connected to the control module; the grating 720 is connected to the second locking component. In a third position, the second locking component drives the grating 720 to block the light beam; in a fourth position, the second locking component drives the grating 720 away from the light beam. When the grating 720 blocks the light beam, the photoelectric element 710 cannot receive the light beam, and the control module outputs a first control command. When the grating 720 moves away from the light beam, the photoelectric element 710 can receive the light beam, and the control module outputs a second control command. The grating 720 determines the locking state by blocking / transmitting the light beam, without mechanical friction or physical contact, avoiding signal drift or failure caused by wear. The photoelectric element 710 is extremely sensitive to changes in the light signal and can provide real-time feedback on the locking state, improving the sensitivity of the control. Photoelectric detection is immune to motor noise and electromagnetic interference from mooring cables, avoiding false triggering.

[0108] In some embodiments, the tethered drone cable deployment and retrieval device further includes a backup power supply 800. The input terminal of the backup power supply 800 is electrically connected to an external power source, and the output terminal of the backup power supply 800 is electrically connected to the drive component 200 to output DC power to the drive component 200. Specifically, the backup power supply 800 is installed inside the housing 400. By providing the backup power supply 800, the drive component 200 can be continuously powered after an external power outage, ensuring the safe landing of the drone.

[0109] Optionally, the backup power supply 800 includes, but is not limited to, a battery. The battery can output DC power.

[0110] A second aspect of this invention provides a tethered unmanned aerial vehicle (UAV). This tethered UAV includes the tethered UAV reel-in / reel-out device of any of the above embodiments. Therefore, the tethered UAV of this embodiment has at least the advantages described above.

[0111] Furthermore, the tethered drone also includes the drone body. An electrical interface 420 is installed on the outside of the housing 400 of the tethered drone cable reeling device. The electrical interface 420 can be connected to an external power source (such as 220 volt AC). One end of the cable inside the tethered drone cable reeling device is connected to the electrical interface 420, and the other end passes through the cable hole on the conductive slip ring, the rotating shaft, and the connecting sleeve 113 and is wound around the connecting rod 114 of the winch 110. Subsequently, guided by the cable assembly 120, the cable extends out of the housing 400 from the operating port of the housing 400 and is electrically connected to the drone body.
