Description

Technical Field

[0001] This utility model relates to the field of tethered unmanned aerial vehicle (UAV) technology, and in particular to a waterproof ground station for tethered UAVs. Background Technology

[0002] Tethered unmanned aerial vehicle (UAV) systems are continuously powered by ground stations, enabling ultra-long-duration operations and offering irreplaceable advantages in military and civilian fields such as communication relay, border patrol, disaster monitoring, and film and television production. However, the ground station, as the core power supply and control unit of the system, operates in complex outdoor environments for extended periods, facing particularly harsh conditions such as rain and humidity.

[0003] Traditional tethered UAV ground stations have significant shortcomings in their waterproof design. On the one hand, during the extension, retraction, and securing of the power cable, rainwater adhering to its surface can easily seep into the device through the cable passage, causing short circuits and component corrosion, severely impacting the device's reliability and lifespan. On the other hand, traditional ground stations have relatively simple drainage designs, often relying solely on simple internal drainage holes, which are insufficient to cope with heavy rain or continuous rain. Accumulated water can easily seep into critical electronic compartments, and rainwater entering the compartments can easily remain, adversely affecting the operation and lifespan of electronic equipment. Summary of the Invention

[0004] Based on the above, a waterproof ground station for tethered drones is provided, which can effectively prevent rainwater from entering the interior of the ground station through the power cord when used in rainy weather.

[0033] In one embodiment, such as Figure 7 As shown, a cable fixing groove 412 is also provided between the water collection tank 416 and the first drainage tank 418. The cable fixing groove 412 is used to connect the water collection tank 416 and the first drainage tank 418, and to clamp the power cable 800, so that the power cable 800 is fixed on the first housing 400.

[0034] In one embodiment, such as Figure 1 Figure 2As shown, the take-up device includes a second housing 100, a drive motor 320, a reel 200, an electric slip ring 310, and an electromagnetic locking pin 330.

The first wire stop plate 210 and / or the second wire stop plate 220 are provided with a plurality of locking holes or locking teeth along the circumferential direction. Alternatively, the outer surface of the first wire stop plate 210 and / or the second wire stop plate 220 is provided with a locking disc 221, which is provided with a plurality of locking holes or locking teeth along the circumferential direction. The electromagnetic latch 330 is fixedly connected to the second housing 100, or slidably connected to the second housing 100 along the axial direction of the reel 200, and elastically connected to the second housing 100 by a spring. The electromagnetic latch 330 drives the pin 331 to engage or disengage from the locking holes or locking teeth, thereby realizing the locking and unlocking action of the reel 200. The second housing 100 is also provided with a second wire passage hole 130 for the power cord 800 to pass through.

[0035] In one embodiment, such as Figure 1-3 As shown, a second drain outlet 421 is provided at the bottom of the first housing 400, and a first drain outlet 111 is provided at the bottom of the second housing 100. A baffle plate 422 is provided around the second drain outlet 421, forming a dam to prevent water from flowing outward. The baffle plate 422 is sealed and fixedly connected to the first housing 400 or integrally formed, and is sealed and connected to the second housing 100. The first drain outlet 111, the dam, and the second drain outlet 421 are sequentially connected to form an internal drainage channel. A sealing cylinder 413 is also included. The sealing cylinder 413 is disposed between the second wire passage hole 130 and the first wire passage hole 411, connecting the second wire passage hole 130 and the first wire passage hole 411. The sealing cylinder 413 is sealed and fixedly connected to the first housing 400 or integrally formed, and is sealed and connected to the second housing 100. The sealing cylinder 413 is used to isolate the power cord 800 in the space between the first wire hole 411 and the second housing 100, to prevent rainwater carried on the power cord 800 from affecting the electronic components inside the drone ground station, and at the same time facilitates the cleaning and maintenance of the drone ground station.

[0039] In one embodiment, such as Figure 1-3 As shown, the locking disc 221 is cylindrical, and its axis coincides with the axis of the reel 200. The cylindrical opening edge of the locking disc 221 has several locking teeth arranged circumferentially. A first through hole 122 is provided on the side wall of the toothed disc mounting groove 121, and the length of the first through hole 122 in the axial direction of the reel 200 is greater than or equal to the distance between the locking disc 221 and the bottom of the toothed disc mounting groove 121, or greater than or equal to the sum of the width of the pin 331 in the axial direction of the reel 200 and the minimum distance at which the pin 331 disengages from the locking teeth. The electromagnetic latch 330 is slidably connected to the second housing 100 in the axial direction of the reel 200 and elastically connected to the second housing 100 via a spring. When the spool 200 obtains a large torque to a set value while locked by the pin 331 and the locking teeth, the locking teeth can spring open the pin 331, allowing the spool 200 to temporarily obtain rotational capacity. This reduces the damage to the locking components caused by the large torque obtained by the spool 200 when locked by the pin 331 and the locking teeth, while still achieving the locking function.

[0059] In one embodiment, such as Figure 5 As shown, the upper housing 410 is also vertically provided with a second fixing post 417, and the lower housing 420 is also vertically provided with a third fixing post 425. It also includes a fixing connecting post 430, which is disposed between the second fixing post 417 and the third fixing post 425. One end of the fixing connecting post 430 is frictionally connected to the second fixing post 417 for positioning and fixing, and the other end is fixedly connected to the third fixing post 425 by screws. This arrangement facilitates the separate mold manufacturing of the upper housing 410 and the lower housing 420, reducing mold manufacturing costs.

[0060] The aforementioned tethered drone waterproof ground station, by setting a retaining ring 530 and a drainage channel on the outer shell, effectively prevents rainwater from entering the interior of the ground station through the power cord 800 during rainy weather, thus avoiding impact on the operation and lifespan of the electronic circuits.

[0061] Based on the above, this application also provides a wire take-up device.

[0062] A take-up device, such as Figure 1 As shown, the system includes a second housing 100, a drive motor 320, a reel 200, an electric slip ring 310, and an electromagnetic locking pin 330. One end of the reel 200 is coaxially and fixedly connected to the rotor of the drive motor 320 or connected via a reducer, while the other end is rotatably connected to the second housing 100, allowing the drive motor 320 to drive the reel 200, causing it to rotate relative to the second housing 100. One end of the electric slip ring 310 is coaxially and fixedly connected to the reel 200, while the other end is fixedly or rotatably connected to the second housing 100. This allows the reel 200 to provide power input to the power line 800 wound on it while simultaneously rotatably connected to the second housing 100. The stator of the drive motor 320 is fixedly connected to the second housing 100. A first wire-blocking plate 210 is provided at one end of the reel 200, and a second wire-blocking plate 220 is provided at the other end. The reel 200 is used to wind the power cord 800. The first wire-blocking plate 210 and the second wire-blocking plate 220 are used to limit the winding range of the power cord 800 on the reel 200 and to prevent the power cord 800 from contacting or rubbing against the inner wall of the second housing 100. The first wire-blocking plate 210 and / or the second wire-blocking plate 220 are provided with a plurality of locking holes or locking teeth along the circumferential direction. Alternatively, the outer surface of the first wire-blocking plate 210 and / or the second wire-blocking plate 220 is provided with a locking disc 221, which is provided with a plurality of locking holes or locking teeth along the circumferential direction. The electromagnetic latch 330 is fixedly connected to the second housing 100, or slidably connected to the second housing 100 along the axial direction of the reel 200, and elastically connected to the second housing 100 by a spring. The electromagnetic latch 330 drives the pin 331 to engage or disengage from the lock hole or locking teeth, thereby locking and unlocking the wire reel 200. The second housing 100 also has a second wire hole 130 for the power cable 800 to pass through.

[0063] In one embodiment, such as Figure 2 Figure 3 Figure 4As shown, the second wire passage hole 130 is eccentrically set relative to the axis of the spool 200. That is, on the vertical projection plane, the second wire passage hole 130 is located on one side of the axis of the spool 200, or more than half of its area is located on one side of the axis of the spool 200, so that the edge of the second wire passage hole 130 is always far away from the vertical tangent on one side of the spool 200, thereby applying a lateral downward or lateral upward pressure to the power line 800 passing through it, so that the power line 800 generates a tension force opposite to its direction of movement. Alternatively, a pressure bar 140 may be provided within the second housing 100. The pressure bar 140 is parallel to the axis of the reel 200 and is fixedly or detachably fixedly connected to the second housing 100 to facilitate adjustment of the position of the pressure bar 140 relative to the reel 200. The power cord 800 passes sequentially through the reel 200, the pressure bar 140, and the second wire hole 130. The pressure bar 140 applies lateral downward or lateral upward pressure to the power cord 800, causing the power cord 800 to generate a tension force opposite to its direction of movement. This arrangement allows the power cord 800 to be tightened more firmly and wound more evenly when the reel 200 rotates to take in the cord.

[0064] In one embodiment, such as Figure 4 As shown, the second wire guide hole 130 is an elongated hole, and its length direction is spatially perpendicular to the axis of the spool 200.

[0065] In one embodiment, a sleeve or several slip rings (not shown) are also included, which are fitted onto the wire pressing rod 140 and slidably connected to the wire pressing rod 140 to reduce the friction between the power cord 800 and the wire pressing rod 140.

[0066] In one embodiment, such as Figure 1 Figure 2 Figure 3 As shown, a gear plate mounting groove 121 is provided on the inner side of the second housing 100 near the first baffle plate 210 and / or the second baffle plate. A locking disc 221 is disposed within the gear plate mounting groove 121 and is clearance-fitted with the inner wall of the gear plate mounting groove 121. A first through hole 122 is provided on the side wall or bottom of the gear plate mounting groove 121 for a pin 331 to pass through, facilitating engagement or disengagement of the pin 331 with the locking disc 221.

[0067] In one embodiment, such as Figure 1 Figure 2 Figure 3As shown, the locking disc 221 is cylindrical, and its axis coincides with the axis of the reel 200. The cylindrical opening edge of the locking disc 221 has several locking teeth arranged along its circumference. A first through hole 122 is provided on the side wall of the toothed disc mounting groove 121, and the length of the first through hole 122 in the axial direction of the reel 200 is greater than or equal to the distance between the locking disc 221 and the bottom of the toothed disc mounting groove 121, or greater than or equal to the sum of the width of the pin 331 in the axial direction of the reel 200 and the minimum distance at which the pin 331 disengages from the locking teeth. The electromagnetic latch 330 is slidably connected to the second housing 100 along the axial direction of the reel 200, and is elastically connected to the second housing 100 via a spring. This allows the reel 200 to obtain a large torque when the latch 331 is locked with the locking teeth, reaching a set value. At this point, the locking teeth can spring open the latch 331, allowing the reel 200 to temporarily gain rotational capacity. This reduces the damage to the locking components caused by the large torque obtained by the reel 200 when the latch 331 is locked with the locking teeth, while still achieving the locking function.

[0068] In one embodiment, such as Figure 1 Figure 2 As shown, the second housing 100 is also provided with a sliding mounting base 123, and the electromagnetic locking pin 330 is slidably connected to the sliding mounting base 123 in the axial direction of the roller 200. One end of the sliding mounting base 123 is provided with a stop plate 125, and the electromagnetic locking pin 330 is connected to the stop plate 125 by a spring. The sliding mounting base 123 has a second through hole 124 for the insertion pin 331 to pass through, preventing the insertion pin 331 from contacting the sliding mounting base 123.

[0069] In one embodiment, such as Figure 1 Figure 2 As shown, the second wire guide plate 220 is detachably connected to the hub of the reel 200, and the power output terminal of the slip ring 310 is located between the second wire guide plate 220 and the hub of the reel 200. This arrangement facilitates the electrical connection between the power cable 800 wound on the hub of the reel 200 and the slip ring 310, and also allows for a higher degree of integration between the reel 200 and the slip ring 310, resulting in more efficient power transmission and power transfer.

[0070] In one embodiment, such as Figure 1 Figure 2 Figure 3 As shown, it also includes a cylindrical shaft 222. The cylindrical shaft 222 is coaxially arranged with the reel 200 and is fixedly connected to the reel 200 or integrally formed with it. The reel 200 is rotatably connected to the second housing 100 through the cylindrical shaft 222. The cylindrical shaft 222 is also used to pass through the power transmission line, so that the slip ring 310 can be connected to the external power supply.

[0071] In one embodiment, such as Figure 1-4As shown, a bearing seat is provided on the second housing 100, and the bearing seat connects the inner and outer sides of the second housing 100. The cylindrical shaft 222 is connected to the bearing seat through a bearing, realizing the rotational connection relationship between the cylindrical shaft 222 and the second housing 100.

[0072] In one embodiment, such as Figure 1 Figure 2 Figure 3 As shown, the bottom of the second housing 100 is also provided with a first drain outlet 111, which allows water inside the second housing 100 to drain naturally by gravity. In one embodiment, the bottom of the second housing 100 is inclined, and the first drain outlet 111 is located at the bottom of the slope and / or on the slope surface, so that water inside the second housing 100 can collect at the first drain outlet 111 for easy discharge.

[0073] In one embodiment, such as Figure 1 Figure 2 Figure 3 As shown, the second housing 100 includes a left housing 110 and a right housing 120 that are fixedly connected. The stator of the drive motor 320 is mounted on the left housing 110, and the gear plate mounting groove 121 and the electromagnetic locking pin 330 are disposed on the right housing 120.

[0074] In one embodiment, such as Figure 1 Figure 2 Figure 3 As shown, a first drain outlet 111 is provided at the bottom of the left housing 110.

[0075] In one embodiment, such as Figure 1 Figure 2 As shown, the left housing 110 is also provided with a motor mounting base 112 for fixing the stator of the drive motor 320, and a circuit board 340 for controlling and driving the drive motor 320 to rotate is provided on the back of the motor mounting base 112.

[0076] In one embodiment, the drive motor 320 adopts brushless FOC control, which makes it compact, has high torque, and makes the winding and unwinding process smoother.

[0077] The above-mentioned take-up device integrates the spool 200 and the electric slip ring 310, and sets a locking disc 221 and an electromagnetic locking pin 330 at the end of the spool 200 to effectively prevent the spool 200 from reversing and loosening the line during transportation, thus avoiding the problem of the line getting stuck at the source.

[0078] Based on the above, this application also provides a ground station for unmanned aerial vehicles (UAVs).

[0079] A ground station for unmanned aerial vehicles (UAVs) includes a retractor for any of the above-mentioned features.

[0080] In one embodiment, such as Figure 1 As shown, the UAV ground station includes a first housing 400, which surrounds and is fixedly connected to a second housing 100. The first housing 400 has a first cable pass-through hole 411 for a power cable 800 to pass through. The first cable pass-through hole 411 communicates with a second cable pass-through hole 130. The second housing 100 and the first housing 400 enclose a space for installing the UAV ground station's electronic devices.

[0081] In one embodiment, such as Figure 1 As shown, a wire-fixing groove 412 is provided on the first housing 400. The wire-fixing groove 412 is used to clamp the power cord 800, so that the power cord 800 is detachably connected to the first housing 400.

[0082] In one embodiment, such as Figure 1 As shown, it also includes a retaining member 520, which is embedded in the cable fixing groove 412 and fixedly connected to the first housing 400. The retaining member 520 is used to clamp the power cord 800 and is detachably fixedly connected to the power cord 800, thereby achieving the purpose of detachably fixing the power cord 800 to the first housing 400 and facilitating disassembly and assembly. In this embodiment, since the power cord 800 needs to be frequently connected and disconnected from the first housing 400, it is easy to cause wear or damage to the connection part. The present invention adds a retaining member 520 at the connection between the power cord 800 and the first housing 400, which can effectively solve this problem. When the retaining member 520 is worn or damaged and cannot properly fix the power cord 800, this small part of the retaining member 520 can be directly replaced without scrapping the entire first housing 400, which can greatly reduce the use and maintenance costs.

[0083] In one embodiment, such as Figure 1 As shown, a retaining ring 530 is provided inside the first wire passage hole 411. The retaining ring 530 is fixedly connected to the first wire passage hole 411 in the direction of movement of the power cord 800, so that it will not move as the power cord 800 is pulled out or retracted. It can be fixedly connected, slidably connected, or have a clearance fit in the circumferential direction. The retaining ring 530 is mainly used to block water on the power cord 800, preventing water from flowing into the first wire passage hole 411.

[0084] In one embodiment, the retaining ring 530 is made of rubber.

[0085] In one embodiment, such as Figure 5As shown, it also includes a sealing cylinder 413, which is disposed between the second wire passage hole 130 and the first wire passage hole 411. The second wire passage hole 130, the sealing cylinder 413, and the first wire passage hole 411 are sequentially connected for the passage of the power cable 800. The sealing cylinder 413 is sealed to the second housing 100. The sealing cylinder 413 is sealed and fixedly connected to the first housing 400 or integrally formed. The sealing cylinder 413 is used to isolate the power cable 800 in the space between the first wire passage hole 411 and the second housing 100, preventing rainwater carried on the power cable 800 from affecting the electronic components inside the drone ground station, while also facilitating the cleaning and maintenance of the drone ground station.

[0086] In one embodiment, the sealing cylinder 413 is a cylindrical or prismatic cylinder.

[0087] In one embodiment, such as Figure 1-3 As shown, the bottom of the second housing 100 is provided with a first drain outlet 111, and the bottom of the first housing 400 is provided with a second drain outlet 421.

The first drain outlet 111, the dam, and the second drain outlet 421 are connected in sequence to form the drainage channel of the UAV ground station, allowing water inside the second housing 100 to be naturally discharged by gravity.

[0088] In one embodiment, the bottom of the first housing 400 is inclined within the dam, and the second drain outlet 421 is located at the bottom of the slope, so that water can be collected and discharged at the second outlet.

[0098] In one embodiment, such as Figure 1 As shown, it also includes a power cord 800. One end of the power cord 800 is fixedly connected to the reel 200 and electrically connected to the slip ring 310. The other end is provided with a power connector 810, which is used to connect to the tethered drone and supply power to the tethered drone. In addition, after the cord is retracted, it is snapped into the cable tray 412 or the retainer 520 for easy storage.

[0099] In one embodiment, such as Figure 1 Figure 5 Figure 6 As shown, the first housing 400 includes an upper housing 410 and a lower housing 420 that are fixedly connected vertically. A first wire passage hole 411, a wire fixing groove 412, a sealing cylinder 413, a first mounting hole 414, and a first fixing post 415 are provided on the upper housing 410. A second drain outlet 421, a baffle plate 422, a third wire passage hole 423, a power supply mounting base 424, and a heat dissipation hole 426 are provided on the lower housing 420.
