Description

Technical Field

[0001] This utility model mainly relates to the field of intelligent equipment integration technology for unmanned aerial vehicles (UAVs), specifically to a rapid take-off device for UAVs based on a vehicle-mounted platform. Background Technology

[0002] With the rapid development of drone technology, its applications in emergency rescue, power line inspection, geographic surveying, and security monitoring are becoming increasingly widespread. In various emergency operation scenarios, fire rescue, which directly relates to the safety of people's lives and property, places even more stringent demands on equipment response speed and operational efficiency. Tethered firefighting drones, with their advantages of long endurance, high payload capacity, and ability to carry fire extinguishing agents or reconnaissance equipment, have gradually become key rescue equipment for complex fire situations such as high-rise building firefighting, forest fire monitoring, and hazardous chemical spill response.

[0003] In actual firefighting operations, tethered firefighting drones need to rely on mobile carriers for rapid deployment across regions. Fire trucks, as the core mobile platform for fire rescue, possess powerful engines, stable load-bearing capacity, and comprehensive emergency support, making them an ideal integrated carrier for tethered firefighting drones. By integrating the tethered firefighting drone system into a fire truck, the drone can be transported seamlessly from storage to operational status, effectively shortening equipment delivery time.

[0004] Furthermore, the high sensitivity of fire and rescue operations to the "golden rescue time" necessitates that tethered firefighting drones possess a rapid response capability of "stop and take off immediately" upon arrival at the scene. This capability is crucial for quickly completing critical tasks such as fire reconnaissance, fire source location, and initial fire suppression, thus gaining valuable time for subsequent rescue operations. Therefore, achieving efficient integration of tethered firefighting drones with fire truck platforms and constructing a safe and reliable automated rapid takeoff mechanism has become a significant technological breakthrough for improving fire and rescue emergency response capabilities and safeguarding people's lives and property.

[0005] Firefighting operations are characterized by significant complexity and variability in their environments. After a fire breaks out, the scene is often accompanied by extreme conditions such as dense smoke, scorching heat, confined spaces, or dense obstacles. The deployment of traditional drones requires manual handling, on-site assembly, and debugging before takeoff, which is not only time-consuming (usually 10-15 minutes) but also exposes operators to hazardous environments and poses high safety risks.

[0006] Meanwhile, firefighting scenarios place extremely stringent technical requirements on drone take-off and landing platforms. For medium to large-sized drones with vertical take-off and landing capabilities, even with real-time differential positioning or visual positioning assistance, the horizontal deviation of their landing accuracy still needs to be controlled within approximately 0.2 meters. This accuracy requirement directly determines the size design of the take-off and landing platform: the platform's side length or diameter must exceed the drone's maximum external dimensions by 30% to 50%, and a buffer zone of at least 0.5-1 meter must be reserved at the platform's edge to prevent airflow disturbances during take-off from causing the fuselage to deviate and collide with the edge, thus ensuring take-off and landing safety.

[0007] In relevant existing patent applications, such as patent application CN205891274U "A Rescue Drone Vehicle-Mounted Platform and Rescue Vehicle," the proposed technical solution includes a storage structure, a limiting structure, support and adjustable feet, and a level measuring device. The storage structure uses a storage frame or storage box to store and remove the drone landing pad. The limiting structure ensures the accuracy of the drone's position during storage. The support and adjustable feet provide platform support and level adjustment. A bubble level is installed on the drone landing pad to monitor its levelness. This solution achieves the advantages of a small space occupation and convenient use for the vehicle-mounted platform. The drone landing pad can be used directly while in vehicle mode, and it can be pulled out of the vehicle for take-off and landing operations. It can also be leveled on uneven ground to prevent dust from being stirred up. Patent application CN210235345U, "A vehicle-mounted take-off and landing device for unmanned aerial vehicles with dust and rain protection," designs a technical solution that includes a vehicle-mounted base, a shell, a take-off and landing platform, a drive mechanism, and a sealing mechanism. The take-off and landing platform is moved and sealed through the coordinated action of a drive motor, gears, and toothed plates. Combined with a deflector plate, rainwater is diverted, thereby realizing the automated take-off and landing of the unmanned aerial vehicle and providing rain and dust protection, which improves the efficiency of equipment use to a certain extent.

[0008] However, the aforementioned existing patented technologies are not sufficiently applicable to the rapid takeoff scenario of medium and large-sized firefighting drones mounted on vehicles. Specifically, if a lifting device is designed to accommodate medium and large-sized drones, it can easily lead to an increase in the vertical dimension, causing the entire platform vehicle to exceed the road height limit. At the same time, the operating procedure adopted in patent application CN205891274U is relatively cumbersome, relying on manual completion of key adjustment steps, which is time-consuming and cannot meet the rapid response requirements of "stop and take off immediately" for drones in fire emergency scenarios. Utility Model Content

[0009] In view of the technical problems existing in the prior art, this utility model provides a vehicle-mounted platform-based rapid take-off device for unmanned aerial vehicles that effectively improves the response efficiency of emergency operations.

[0010] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: A rapid take-off device for unmanned aerial vehicles (UAVs) based on a vehicle-mounted platform includes a fire truck, a cable winch, a UAV, a water hose assembly, an electric cylinder assembly, and a locking device.

The cable winch is located at the front end of the platform, the water hose device is installed on the tailgate, the UAV is located in the middle of the platform, and the locking device is located on the platform for locking or releasing the UAV's landing gear.

[0011] As a further improvement to the above technical solution: The left carriage door consists of a left side panel and a left top panel. The lower end of the left side panel is hinged to a fixed cover, and one end of the left top panel is hinged to the upper end of the left side panel. The right carriage door consists of a right side panel and a right top panel. The lower end of the right side panel is hinged to a fixed cover, and one end of the right top panel is hinged to the upper end of the right side panel. The left top plate has a downward protruding ridge at one end, and the right top plate has a groove at one end; the protruding ridge at the end of the left top plate and the groove at the end of the right top plate form a nested structure; or the left top plate has a groove at one end, and the right top plate has a downward protruding ridge at one end, and the groove at the end of the left top plate and the protruding ridge at the end of the right top plate form a nested structure.

[0012] The electric cylinder assembly includes a first electric cylinder, a second electric cylinder, and a third electric cylinder; the fixed end of the first electric cylinder is hinged to a fixed cover, and the movable end is hinged to the outer surface of the left or right side panel; the fixed end of the second electric cylinder is hinged to the inner surface of the left or right side panel, and the movable end is hinged to the inner surface of the left or right top panel; the fixed end of the third electric cylinder is hinged to the fixed cover, and the movable end is hinged to the outer surface of the tailgate.

[0013] The left side panel and the left top panel are divided into multiple segments along the length of the vehicle body; the right side panel and the right top panel are divided into multiple segments along the length of the vehicle body; each segment of the left side panel or the right side panel is equipped with a first electric cylinder; each segment of the left top panel and the right top panel is equipped with a second electric cylinder.

[0014] After the left and right top plates are fully opened, the left top plate and the left side plate are arranged at a certain angle, as are the right top plate and the right side plate, so that the left and right top plates can provide edge protection for the drone to prevent it from slipping when it takes off or lands.

[0015] The locking device includes a guide rail, a first linear motor, two locking beams, a second linear motor, a lead screw, and a rotary motor; the platform is provided with mounting holes, the guide rail is fixedly installed in the mounting holes, the bases of the first linear motor and the second linear motor are slidably installed on the guide rail, and the bases of the first linear motor and the second linear motor are provided with a through threaded hole parallel to the arrangement direction of the guide rail, and the rotation direction of the threaded holes in the bases of the two motors is opposite. The rotary motor is fixedly mounted on the end of the guide rail, and the output end of the rotary motor is connected to a lead screw, which passes through the threaded holes on the bases of the first linear motor and the second linear motor. The two locking beams are located at the top of the output shafts of the first linear motor and the second linear motor, respectively.

[0016] Both locking beams have arc grooves on their inner sides, and the diameter of the arc grooves is the same as the outer diameter of the landing gear.

[0017] The locking devices are in multiple sets and are installed directly below the landing gear of the drone.

[0018] The fire hose device includes a cabin and a fire hose, the fire hose being located inside the cabin, and the cabin being equipped with a rotating door.

[0019] The cable winch includes a drum and a cable, the cable being wound on the drum.

[0020] Compared with the prior art, the advantages of this utility model are: This invention utilizes an electric cylinder to automatically unfold a folding cargo box (including side panels, top panel, and tail door) in a very short time, forming an extended take-off and landing platform. The entire process, from vehicle coming to a complete stop to providing a take-off platform for the drone, requires no manual intervention, significantly shortening deployment time and greatly improving deployment efficiency. It achieves "stop and fly immediately," meeting the "golden response time" requirements of scenarios such as firefighting and emergency rescue, effectively improving emergency response efficiency, and saving valuable time for critical stages such as fire reconnaissance and personnel search and rescue, indirectly reducing the risk of loss of life and property. The locking device employs multiple adjustable clamping mechanisms with multi-directional adjustable locking ranges. Through the coordinated control of linear motors and lead screws, it achieves multi-directional precise locking and rapid release of the drone's landing gear, reducing reliance on landing accuracy. Simultaneously, reliable locking of the drone reduces vibration damage during transportation, comprehensively enhancing safety performance, extending equipment lifespan, and reducing subsequent maintenance costs.

[0021] This invention integrates the drone, cable winch, and water hose device into a single vehicle, providing a stable guarantee for the continuous power and water supply of the tethered drone, ensuring a continuous supply of energy and resources during operation. Simultaneously, the cable winch and water hose device are positioned at the front and rear of the vehicle, further reducing the vehicle's height and improving its maneuverability.

This invention features a simple structure, a reasonable and compact spatial layout, and convenient and efficient operation, enabling rapid take-off of drones. It also boasts advantages such as a high degree of automation and reliable safety performance, making it suitable for vehicle-mounted deployment scenarios for medium to large-sized drones.

[0022] This utility model's drone vehicle-mounted platform employs a fully automated control process for rapid deployment and folding, reducing reliance on professional operators and avoiding exposure to hazardous environments such as high temperatures, dense smoke, and confined spaces. This reduces operational safety hazards at the source and effectively saves labor costs. Transporting drones via a platform vehicle overcomes the stringent environmental limitations of traditional devices, further expanding the practical application scenarios of drones and enhancing operational flexibility and environmental adaptability.

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1 As shown, the vehicle-mounted platform-based rapid take-off device provided in this embodiment of the present invention includes a fire truck 100, a cable winch 200, a drone 300, a water hose device 400, an electric cylinder assembly 500, and a locking device 600. Fire truck 100 is a platform vehicle with a driver's cab. Cable winch 200 is located at the front of the fire truck 100's body. UAV 300 is located in the middle of the fire truck 100's body. Hose assembly 400 is installed at the rear of the fire truck 100's body. Electric cylinder assembly 500 is located on the fire truck 100's door. Locking device 600 is located on the landing platform (on the subsequent platform 105) directly below the UAV 300's landing gear. Specifically, the fire truck 100's body includes a front door 101, a left side door 102, a right side door 103, a rear door 104, a platform 105, and a fixed cover 106, etc.; the front door 101 is located directly behind the driver's cab and is a fixed side, such as... Figure 2 As shown, the left carriage door 102 consists of a left side panel 1021 and a left top panel 1022. The lower end of the left side panel 1021 is hinged to the fixed cover 106, and one end of the left top panel 1022 is hinged to the upper end of the left side panel 1021. The right carriage door 103 consists of a right side panel 1031 and a right top panel 1032, and their connection method is the same as that of the left carriage door 102. The left top panel 1022 has a downward-facing protruding ridge at its end, and the right top panel 1032 has a groove at its end. Thus, the ends of the left top panel 1022 and the right top panel 1032 form a nested structure, ensuring the stability of the left and right carriage doors in the folded state. Of course, in this embodiment, the protruding ridge can also be located on the right top panel 1032, and the groove can be located on the left top panel 1022.

[0040] The tailgate 104 is located at the rear of the entire fire truck 100 body and is hinged to the fixed cover 106. The platform 105 is located in the plane surrounded by all the compartments and serves as the take-off and landing area for the UAV 300.

[0041] Due to the long body length, to ensure structural reliability, the left carriage door 102 and the right carriage door 103 can be configured as two or more identical sections.

[0042] Specifically, the cable 201 in the cable winch 200 is wound on the drum, and its end is connected to the cable interface on the UAV base 302 to continuously power the propeller motor of the UAV 302. The landing gear 301 of the UAV 300 rests on the platform 105. In addition to the cable interface, the base 302 is also equipped with a hose interface, which can be connected to one end of the fire hose 401 of the fire hose device 400. The other end of the fire hose 401 is connected to a fire hydrant or other water source to continuously supply water for fire fighting. The fire hose 401 is stored inside the cabin, and its cabin door 402 can be rotated open for easy maintenance.

[0043] Specifically, the electric cylinder assembly 500 includes a first electric cylinder 501, a second electric cylinder 502, and a third electric cylinder 503 for driving the tailgate 104 to rotate. One electric cylinder is installed on each independently rotatable section of the carriage body. Figure 2 and Figure 13As shown. The fixed end of the first electric cylinder 501 is hinged to the fixed cover 106, and the moving end is hinged to the outer surface of the left side plate 1021 or the right side plate 1031, for driving the left side plate 1021 or the right side plate 1031 to rotate; the fixed end of the second electric cylinder 502 is hinged to the inner surface of the left side plate 1021 or the right side plate 1031, and the moving end is hinged to the inner surface of the left top plate 1022 or the right top plate 1032; the fixed end of the third electric cylinder 503 is hinged to the fixed cover 106, and the moving end is hinged to the outer surface of the tailgate 104.

[0044] Specifically, there are multiple sets (e.g., four sets) of locking devices 600, installed directly below the landing gear 301 of the UAV 300, to securely lock the landing gear of the UAV 300, effectively ensuring the storage safety and structural reliability of the UAV in non-flight mode. Of course, in other embodiments, the number of locking devices 600 can also be two, six, or more sets, depending on the actual situation.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the locking device 600 consists of a guide rail 601, a first linear motor 602, a locking beam 603, a second linear motor 604, a lead screw 605, and a rotary motor 606; wherein the locking device 600 is installed as a whole in the mounting hole of the platform 105. The guide rail 601 has two rows of mounting holes for fixed connection with the platform 105. The bases of the first linear motor 602 and the second linear motor 604 are sliders that match the guide rail 601 and can move freely back and forth in a linear motion within the guide rail 601. The bases of the first linear motor 602 and the second linear motor 604 are provided with a through threaded hole parallel to the direction of the guide rail 601. The threads of the two motor bases are rotated in opposite directions. The rotary motor 606 is fixedly installed at the end of the guide rail 601. The output end of the rotary motor 606 is connected to the lead screw 605, which passes through the threaded hole on the base of the first linear motor 602 and the second linear motor 604. Locking beams 603 are fixedly connected to the top of the output shafts of the first linear motor 602 and the second linear motor 604, respectively. The locking beam 603 has a section of arc groove structure, the diameter of which is the same as the outer diameter of the landing gear 301.

[0046] like Figure 3 As shown, in the initial state, the output shafts of the first linear motor 602 and the second linear motor 604 are in a retracted state, the upper surface of the locking beam 603 is flush with the upper surface of the platform 105, and the first linear motor 602 and the second linear motor 604 are in a distanced state. Figure 4As shown, the rotary motor 606 is not working, while the first linear motor 602 and the second linear motor 604 work simultaneously. The locking beam 603 begins to rise, and after reaching the set height, the two linear motors stop working. Figure 5 As shown, the rotary motor 606 starts working. Due to the side effects of the threads, the two motor bases have opposite rotation directions of the internal threaded holes. When the lead screw 605 rotates, the first linear motor 602 and the second linear motor 604 move towards each other along the guide rail 601 until they move to the left and right locking beams 603 to form a ring to clamp the landing gear 301. Then the rotary motor 606 stops working.

[0047] like Figure 14 As shown, in the non-operating state, all the carriages are folded down to form a sealed space, and the drone 300 is placed inside the carriage. Figure 11 As shown, the four landing gears 301 of the drone 300 are firmly locked by the locking beams 603 of the locking device 600, facilitating road transport. Upon arrival at the work site, after parking, the drone 300 needs to take off from the platform 105 within a short time, therefore the truck body needs to be quickly deployed to provide sufficient platform conditions for the drone to take off.

[0048] To shorten the opening time, the tailgate 104 can be opened simultaneously with the left and right cargo doors 102 and 103. The opening process of the left and right cargo doors 102 is as follows: Figure 6 As shown, to open the left carriage door 102 and the right carriage door 103, the second electric cylinder 502 first extends, pushing the left top plate 1022 to flip outward. At this time, the protruding ridge at the end of the left top plate 1022 disengages from the groove at the end of the right top plate 1032. Figure 7 As shown, at this point, the left carriage door 102 and the right carriage door 103 no longer form a nested structure; then, the first electric cylinders 501 on both sides retract, causing the left side panel 1021 and the right side panel 1031 to flip outwards until the left / right side panels are fully opened, as shown in the open state. Figure 8 As shown. Next, the second electric cylinders 502 on both sides extend, causing the left top plate 1022 and the right top plate 1032 to continue to rotate outwards until the left / right top plates are fully open, as shown in the open state. Figure 9 As shown, there is a certain angle α (90-150 degrees) between the left top plate 1022 and the left side plate 1021, and between the right top plate 1032 and the right side plate 1031. At this time, the left top plate 1022 and the right top plate 1032 are equivalent to protecting the edge of the UAV 300 to prevent the UAV from slipping when it takes off and lands.

[0049] At this point, the tailgate 104 had already been opened to its proper position by the action of the third electric cylinder 503, and the cargo box was fully extended (as shown). Figure 10As shown), the extended platform, consisting of platform 105, left side panel 1021, right side panel 1031, and tailgate 104, provides ample space for the takeoff of the UAV 300. After all compartments are fully extended, the locking device 600 begins operation. The rotary motor 606 rotates in the opposite direction, the first linear motor 602 and the second linear motor 604 move in opposite directions, and the two locking beams 603 begin to move away, no longer locking the landing gear 301. Then, the rotary motor 606 stops operating, the output shafts of the first linear motor 602 and the second linear motor 604 retract, and the two locking beams 603 sink downwards to be flush with the upper surface of platform 105. Figure 12 As shown. At this time, the drone 300 is in an unrestrained state. After opening the hatch 402 and connecting the cables 201 and fire hose 401 to the corresponding water and electricity interfaces on the base 302, the drone 300 meets the takeoff conditions and can take off vertically from the platform, as shown. Figure 13 As shown.

[0050] Similarly, when the UAV 300 lands on the platform after completing its mission, in addition to the UAV's own GPS positioning function, the locking device 600 can be adjusted within a certain range in the width direction of the fire truck 100 (the first linear motor 602 and the second linear motor 604 have a certain displacement along the guide rail 601), and the locking beam 603 itself has a certain length, which can maintain an effective contact length with the landing gear 301. Therefore, when the UAV 300 lands on the platform 105, its position generally does not need to be manually adjusted. After the UAV 300 lands, the locking device 600 starts to work. The output shafts of the first linear motor 602 and the second linear motor 604 extend, and then the rotary motor 606 rotates. The first linear motor 602 and the second linear motor 604 move towards each other, and the two locking beams 603 begin to clamp and lock the landing gear 301. After the UAV 300 is locked, the cable 201 and the water and electricity interface on the base 302 are disconnected. The cable 201 and the fire hose 401 are retrieved to their initial state, and the hatch is closed.

[0051] The closing and resetting of all the carriage bodies is the reverse process of the unfolding phase. To shorten the time, the tailgate 104 can close simultaneously with the closing of the left carriage door 102 and the right carriage door 103. Specifically, the closing process of the left carriage door 102 and the right carriage door 103 is as follows: the first electric cylinders 501 on both sides extend, pushing the left side panel 1021 and the right side panel 1031 to flip inwards until the left / right side panels are completely closed. The second electric cylinder 502 on the right retracts, causing the right top panel 1032 to flip inwards until the right top panel 1032 is completely closed. At this time, the second electric cylinder 502 on the left retracts, causing the left top panel 1022 to flip inwards until the protrusion of the left top panel 1022 is pressed into the groove of the right top panel 1032. At this point, the left carriage door 102 and the right carriage door 103 form a nested structure, ensuring the structural stability of the entire carriage body under the holding force of the electric cylinder assembly 500. At the same time, the tailgate 104 had already closed in place due to the extension of the third electric cylinder 503, and the entire vehicle was restored to its original position. Figure 14 The state.

[0052] This invention utilizes an electric cylinder to automatically unfold a folding cargo box (including side panels, top panel, and tail door) in a very short time, forming an extended take-off and landing platform. The entire process, from vehicle coming to a complete stop to providing a take-off platform for the drone, requires no manual intervention, significantly shortening deployment time and greatly improving deployment efficiency. It achieves "stop and fly immediately," meeting the "golden response time" requirements of scenarios such as firefighting and emergency rescue, effectively improving emergency response efficiency, and saving valuable time for critical stages such as fire reconnaissance and personnel search and rescue, indirectly reducing the risk of loss of life and property. The locking device 600 employs multiple adjustable clamping mechanisms with multi-directional adjustable locking ranges. Through the coordinated control of a linear motor and lead screw, it achieves multi-directional precise locking and rapid release of the drone 300's landing gear 301, reducing reliance on landing accuracy. Simultaneously, the reliable locking of the drone 300 reduces vibration damage during transportation, comprehensively enhancing safety performance, extending equipment lifespan, and reducing subsequent maintenance costs.

[0053] This invention integrates the drone 300, cable winch 200, and water hose device 400 into the same vehicle, providing a stable guarantee for the continuous power and water supply of the tethered drone, ensuring a continuous supply of energy and resources during operation. Simultaneously, the cable winch 200 and water hose device 400 are positioned at the front and rear of the vehicle, further reducing the vehicle's height and improving its maneuverability. The overall structure of this invention is compact; when folded, it complies with road traffic restrictions, and when unfolded, it provides safe take-off and landing space, adapting to narrow and high-risk environments. This invention features a simple structure, a reasonable and compact spatial layout, and convenient and efficient operation, enabling rapid take-off of drones. It also boasts advantages such as a high degree of automation and reliable safety performance, making it suitable for vehicle-mounted deployment scenarios of medium to large-sized drones.

[0054] This utility model's drone vehicle-mounted platform employs a fully automated control process for rapid deployment and folding, reducing reliance on professional operators and avoiding exposure to hazardous environments such as high temperatures, dense smoke, and confined spaces. This reduces operational safety hazards at the source and effectively saves labor costs. Transporting drones via a platform vehicle overcomes the stringent environmental limitations of traditional devices, further expanding the practical application scenarios of drones and enhancing operational flexibility and environmental adaptability.
