Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and in particular to an integrated charging, decommissioning and storage compartment for unmanned aerial vehicles on the roof of a fire truck. Background Technology

[0002] Currently, there are two types of firefighting equipment equipped with drones in the fire and rescue field: one is a dedicated drone-fire truck, which has a large compartment specifically reserved for storing and accommodating drones and related flight control equipment, enabling drones to be transported and stored on-board. However, the manufacturing cost of the entire vehicle is high, and the technical architecture of the integrated control system is complex, making it difficult for most grassroots fire departments to equip them in large quantities due to budget and maintenance limitations. The other low-cost solution is to add a dedicated drone loading compartment to a conventional fire truck, utilizing the existing fire truck for on-board drone deployment. This requires no modification to the vehicle chassis or main body, making it more economical and the mainstream approach for grassroots fire brigades.

[0003] The existing solution of mounting readily available small firefighting drones on conventional fire trucks has two major drawbacks in actual rescue scenarios, which restrict the timeliness of drone rescue: First, there's the challenge of adapting drones to automated charging. Currently, most grassroots fire and rescue teams still rely on the original factory-supplied storage and transport containers for small firefighting drones, which are placed in the driver's cab. This method of handling is cumbersome. Moreover, placing the drone inside the fire truck's cab makes it susceptible to damage from bumps and knocks during travel. If it's fixed on the roof, access is inconvenient. Furthermore, the onboard batteries of these drones only last about half an hour, requiring frequent recharging during both on-site operations and standby. Existing drone charging interfaces generally have protective covers, preventing automatic charging in conventional fixed cabins. Each use requires manual opening of the cover and unplugging of the charging cable, making the standby recharging process cumbersome and delaying emergency response.

[0004] Second, the timeliness of drone takeoff and operation is insufficient. Fire response requires extremely high response speed for drones to take off for reconnaissance and exploration. The current process for activating ready-made firefighting drones relies on manual operation throughout the entire process: the whole machine must first be taken out of the original storage box and assembled, and then manually turned on by pressing a combination of short and long buttons. The whole operation takes a long time, and the drone cannot be immediately launched and deployed to the rescue after the fire truck arrives at the fire scene, thus missing the golden window for initial fire reconnaissance and personnel search and rescue.

[0005] In summary, the loader compartments of existing conventional fire trucks that carry finished drones can only achieve basic storage functions and cannot simultaneously solve the industry pain points of automatic charging and rapid take-off of drones. Summary of the Invention

[0006] Given the existing technical problems of adapting to automated charging for drones and the insufficient timeliness of rapid take-off operations for drones, an integrated charging, discharging, and storage cabin for drones on the roof of a fire truck is proposed.

[0007] Its purpose is to: avoid drone failure by starting the drone in advance, and to prevent the drone from colliding with the cabin when taking off in advance by fixing the drone; and to realize the drone's automatic charging and automatic on / off functions through auxiliary components.

[0008] The technical solution of the present invention is an integrated charging, discharging and storage compartment for drones on the roof of a fire truck, including a cabin, which is fixedly installed on one side of the fire truck. The interior of the cabin is used to place the drone. The inner side of the cabin is provided with a pair of openable and closable cover doors, and also includes a fixing component for fixing the drone. The fixing assembly includes a placement plate fixed to the inner wall of the cabin, a sorting plate slidably disposed on the surface of the placement plate, a guide rod disposed on the side of the sorting plate, a pull rod disposed on the side of the cover door, a transmission plate disposed at one end of the pull rod, a sliding member disposed on the side of the transmission plate, and a clamping member disposed at the bottom of the transmission plate. The pull rod changes the sliding state of the transmission plate by the opening and closing action of the cover door. The sliding member forces the sorting plate to slide on both sides of the UAV through the guide rod. The clamping member clamps and releases the UAV legs by changing the sliding position of the sliding member.

[0009] Furthermore, there are two cover doors, and each cover door has an electric push rod on its side for controlling opening and closing.

[0010] Furthermore, the middle part of the placement plate is provided with a groove that fits the drone's feet, the sorting plate is slidably disposed on the inner wall of the groove, and the side of the sorting plate is provided with an elastic element for resetting.

[0011] Furthermore, the sliding member includes a track disposed on the surface of the placement plate, and a pair of guide wheels rotatably disposed at the bottom of the transmission plate. One end of the guide wheel is connected to the bottom of the transmission plate via a rotating shaft, and the other end is slidably disposed on the inner wall of the track. The guide wheel is rolled on the side of the guide rod.

[0012] Furthermore, the clamping member includes an elongated hole on the surface of the placement plate, a clamping rod rotatably disposed at the bottom of the transmission plate, a roller rotatably disposed on the side of the clamping rod, and a protrusion disposed on the surface of the placement plate. The protrusion is located on the sliding path of the roller, and the end of the clamping rod near the drone is higher than the upper surface of the bottom of the drone's feet under the gravity of the roller.

[0013] Furthermore, one of the sorting plates has an auxiliary component on its surface, the auxiliary component including a lifting push rod, the movable end of the lifting push rod having a telescopic push rod, the movable end of the telescopic push rod having a connecting frame, the side of the connecting frame having a charging mechanism and a switching mechanism, the connecting frame being directly opposite the charging part and the switching part of the drone.

[0014] Furthermore, the charging mechanism includes a paddle fixedly mounted on the end of the connecting frame. The thickness of the paddle is smaller than the notch in the protective cover of the drone switch. A square hole is provided on one side of the connecting frame. A clip for fixing the drone charging interface is provided on the inner wall of the square hole. One side of the clip is fixedly mounted on the drive push rod.

[0015] Furthermore, the switching mechanism includes a side frame fixedly disposed on the side of the connecting frame, a pressure rod slidably disposed on the inner wall of the side frame, and an elastic element II disposed at the end of the pressure rod.

[0016] Furthermore, a camera can be installed inside the cabin 1 to facilitate observation by the operator, and a cooling fan can also be installed on the side of the cabin 1 to dissipate heat from the interior of the cabin.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves stable storage and rapid response of drones while the fire truck is in motion through integrated cabin design and coordinated use of fixed and auxiliary components. When the drone lands, the grooved slope and guide rod structure can automatically correct its deviation and clamp the legs to ensure the drone is centered. When the cover door is opened, the clamping linkage is released, and the drone can take off directly to avoid delays. At the same time, the auxiliary components can automatically complete the plugging and unplugging of the charging interface, opening and closing of the protective cover and pressing of the switch button, realizing fully unmanned charging and power-on / off operation, improving the dispatch efficiency and automation level of fire-fighting drones.

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1, referring to Figures 1-3 This invention provides a first embodiment of an integrated charging, discharging, and storage compartment for a fire truck roof-mounted drone, comprising a cabin 1 and a cover door 2. Optionally, the cabin 1 is fixed to the roof of the fire truck by welding or bolts. One end of the cover door 2 is rotatably mounted on the inner wall of the cabin 1 via a pivot. To ensure the airtightness of the cabin 1, a pair of cover doors 2 are provided, symmetrically arranged on both sides of the interior of the cabin 1. Optionally, the cover doors 2 can be made of metal or fire-resistant plastic. Furthermore, to ensure normal opening and closing, each cover door 2 is positioned close to... An electric push rod 21 is provided on one side inside the cabin 1. Optionally, the electric push rod 21 can be one or a pair. The fixed end of each electric push rod 21 is rotatably mounted on the inner wall of the cabin 1, and the movable end is rotatably mounted on the side of the cover door 2. Preferably, the electric push rod 21 can be a BML-DJ series product to meet the opening and closing requirements of the cover door 2. Preferably, in order to reduce opening and closing failures, the cover door 2 is preferably made of a plate with multiple bending sections. At the same time, the shape of the cabin 1 should also match the cross-sectional shape of the cover door 2 to ensure the airtightness of the cabin 1.

[0022] Specifically, when the movable end of the electric push rod 21 extends, the cover door 2 opens; conversely, when the movable end of the electric push rod 21 retracts, the cover door 2 closes until the outer surface of the cover door 2 coincides with the top of the cabin 1, at which point it is fully closed.

[0023] Example 2, refer to Figures 4-7 This is the second embodiment of the present invention, which differs from the first embodiment in that: to solve the problem of insufficient timeliness for rapid take-off operations of drones, the drone can be pre-started in the cabin 1. Then, upon arrival at the destination, after the cover door 2 of cabin 1 is opened, the drone can take off directly, thus avoiding delays. To achieve this goal, it is necessary to prevent collisions during take-off of the drone in cabin 1; therefore, the drone in cabin 1 needs to be secured.

[0024] The structure for securing the drone is a fixing component. A placement plate 3 is fixed to the inner wall of the cabin 1 by means of threads or welding. The edge of the placement plate 3 fits against the inner wall of the cabin 1. At the same time, two grooves 31 are provided on the surface of the placement plate 3. The bottom width of the grooves 31 matches the width of the drone's legs, and the two grooves 31 are arranged in parallel with the spacing set according to the spacing of the drone's legs. The inner walls of the grooves 31 are cut on both sides, and the cross-section of each groove 31 is an inverted open trapezoid. Optionally, the placement plate 3 is made of aluminum alloy.

[0025] Specifically, when the drone returns after completing its operation, the operator outside the cabin 1 can control the drone to land inside the cabin 1 and keep the outriggers and the two grooves 31 parallel. After the drone's outriggers contact the grooves 31, under the support of the inclined surface of the grooves 31, even if the drone's outriggers deviate slightly, they can still slide stably into the interior of the grooves 31 under the action of gravity.

[0026] Two adjusting plates 41 are also provided on the inner wall of the groove 31 of the placement plate 3. Each adjusting block has a protrusion on its side. The inner wall of the groove 31 is provided with a sliding elongated hole 471 to limit the protrusion, ensuring that the adjusting block can slide stably on the inner wall of the groove 31. The two adjusting blocks are set on both sides of the UAV feet and are symmetrical about the central axis of the cabin 1. Each adjusting block has a guide rod 42 on both sides. Figure 5 As shown, the bending trend of the two guide rods 42 in the same direction is from narrow to wide from the edge of the placement plate 3 to the center, and they remain parallel at a certain distance at the widest point. Finally, they are connected to the side of the adjustment block. Optionally, the guide rods 42 and the adjustment block can be connected by welding. An elastic element 43 is also provided on the side of each adjustment block away from the drone. The elastic element can help the adjustment block to return to its original position after moving. Preferably, the elastic element can be a metal spring, one end of which is set on the side of the adjustment block by a hook, and the other end is set on the surface of the placement plate 3 by a hook.

[0027] A pull rod 45 is rotatably mounted on the side of each cover door 2 via a pivot. A transmission plate 44 is rotatably mounted on the other end of the pull rod 45 via a pivot. A sliding member 46 and a clamping member 47 are respectively mounted on the bottom of the transmission plate 44.

[0028] Furthermore, the sliding member 46 includes guide wheels 462 disposed at the bottom of both ends of each transmission plate 44, and a track 461 disposed on the surface of the placement block. The side of the guide wheel 462 is rolled on the side of the guide rod 42. Optionally, the contact surface of the guide rod 42 and the guide wheel 462 can be provided with a pattern to increase friction. Preferably, the guide wheel 462 can be made of rubber. The guide wheel 462 is rotatably disposed at the bottom of the transmission plate 44 via a rotating shaft. At the same time, the rotating shaft is also limited to slide on the inner wall of the track 461 to ensure that the guide wheel 462 and the transmission plate 44 do not move up and down during movement. Preferably, the track 461 can be a long strip-shaped through hole penetrating the placement plate 3, and a disc is fixed at the end of the rotating shaft of the guide wheel 462, so that the track 461 is within the space formed by the guide wheel 462 and the disc, thereby ensuring that the transmission plate 44 and the guide wheel 462 cannot move up and down.

[0029] Furthermore, the clamping member 47 includes a clamping rod 472 rotatably mounted on the bottom of each transmission plate 44 via a rotating shaft, and an elongated hole 471 opened on the surface of the placement plate 3. Preferably, the clamping plate and the elongated hole 471 are both located on the center line of the placement plate 3 and perpendicular to the drone's feet. Each clamping rod 472 has two rollers 473 rotatably mounted on its end away from the drone via a cylindrical bracket. Preferably, the two rollers 473 are coaxially mounted and placed perpendicular to the elongated hole 471. A protrusion 474 is provided on the rolling path of each roller 473. Preferably, the protrusion 474 is fixedly mounted on the surface of the placement plate 3 by bolts. It is worth noting that before the roller 473 contacts the protrusion 474, the clamping rod 472, under the gravity of the roller 473, slightly tilts upward at the end near the drone foot and remains above the upper surface of the bottom of the drone foot. When the clamping rod 472 clamps the drone foot, its end near the drone must be a certain distance beyond the drone foot, which can ensure that when the cover door 2 is fully opened, the clamping rod 472 just leaves the drone foot.

[0030] Specifically, after completing its work, the drone flies back to cabin 1 under the control of the operator. The operator uses a camera to park the drone in the middle of cabin 1, and the drone's legs can fall into the range of the groove 31. Under the action of the drone's gravity, the drone's legs slide along the side of the groove 31 into the bottom of the groove 31, and then the cover door 2 closes.

[0031] During the closing process of the cover door 2, the pull rod 45 is subjected to the pressure of the cover door 2, which in turn drives the transmission plate 44 to slide. The transmission plate 44 drives the guide wheel 462 to slide along the side of the guide rod 42 and presses the guide rods 42 on both sides of the elongated hole 471 towards the middle. This causes the adjustment block to overcome the elasticity of the elastic element 43 and move closer to the drone's feet. When the guide wheel 462 slides to the parallel part of the guide rod 42 on the same side, the adjustment block will clamp the drone's feet from both sides of the drone. This step will adjust the drone's attitude and adjust the drone to the center of the cabin 1. On the one hand, it can prevent the drone from tilting during takeoff, and on the other hand, it can facilitate clamping the drone's feet.

[0032] While the adjusting block clamps the drone's feet, the clamping rod 472 also moves to directly above the lower part of the drone's feet. At this time, the roller 473 rolls above the protrusion 474. As the transmission plate 44 moves, the clamping rod 472 clamps the drone's feet downwards under the action of the roller 473. This step ensures that the drone is completely in contact with the bottom of the groove 31, allowing for further position adjustment of the drone and ensuring that the drone is in the center of the placement plate 3. It also serves to fix the drone in place.

[0033] In actual use, when the fire truck approaches the fire scene, the drone operator can pre-launch the drone. If the drone is initially unable to open due to restraints, upon arrival at the fire scene, the operator remotely controls the cover door 2 to open. During the opening of the cover door 2, the adjusting block moves away from the drone's feet, and the clamping rod 472 also moves away from above the drone's feet. When the cover door 2 is fully open, both clamping rods 472 simultaneously leave the drone's feet, allowing the drone to take off directly and quickly engage in rescue work, avoiding the problem of insufficient time for rapid drone takeoff operations. The remaining structure is the same as in Embodiment 1.

[0034] Example 3, referring to Figures 5-10 This is the third embodiment of the present invention, which differs from the second embodiment in that: in order to solve the problem of automatic charging adaptation of drones in the cabin 1, an auxiliary component 48 is provided on the side of one of the organizing plates 41. The auxiliary component 48 includes a lifting push rod 481 fixed to the surface of the organizing plate 41 by bolts. The movable end of the lifting push rod 481 is fixed to a telescopic push rod 482 by a plastic bracket and bolts. Further, the telescopic rod faces the side of the drone where the charging port and switch button are provided. The movable end of the telescopic push rod 482 is fixed to a connecting frame 483 by a plastic bracket and bolts. The side of the connecting frame 483 is provided with a charging mechanism and a switching mechanism. The connecting frame 483 is directly opposite the charging part and the switching part of the drone.

[0035] The charging mechanism includes a lever 484 fixedly mounted on the end of the connecting frame 483. The lever 484 has good elasticity and can return to its original position after deformation. Optionally, the lever 484 is connected to the end of the connecting frame 483 by bolts or welding. Further, the thickness of the lever 484 is smaller than the notch of the protective cover plate at the drone switch. A square hole is provided on one side of the connecting frame 483, located above the lever 484. The inner wall of the square hole is provided with a clamp 485 for fixing the drone charging interface. Preferably, the clamp 485 is made of a metal material with good elasticity, such as iron or aluminum sheet, so that the clamp 485 can directly generate a clamping force on the drone charging connector through deformation. At the same time, the outermost end of the charging connector in the clamp 485 does not exceed the outermost end of the lever 484. One side of the clamp 485 is fixedly mounted on a drive push rod 486. Preferably, the drive push rod 486 is an electric push rod 21, and the Limtec mini electric push rod 21LAM series can be selected.

[0036] The switching mechanism includes a side frame 487 fixedly mounted on the side of the connecting frame 483, and a pressure rod 488 slidably mounted on the inner wall of the side frame 487. Further, compared to the charging connector and the lever 484, the end of the pressure rod 488 is closer to the drone. A second elastic element 489 is disposed at the end of the pressure rod 488. Preferably, the second elastic element 489 can be a spring, with one end fixedly mounted on the end of the pressure rod 488 and the other end fixed to the side of the side frame 487. Further, the lever 484, the clip 485, and the pressure rod 488 are at different heights.

[0037] Specifically, the height of the telescopic push rod 482 can be changed by the lifting push rod 481, and the distance between the connecting frame 483 and the drone can be changed by the telescopic push rod 482. When charging is required, the telescopic push rod 482 controls the connecting frame 483 to move closer to the drone, and causes the paddle 484 to press against the surface of the drone. Then, the lifting push rod 481 controls the connecting frame 483 to move down. As the connecting frame 483 moves down, the paddle 484 slides into the notch of the charging port protective cover. During the downward movement of the lifting push rod 481, the paddle 484 uses its own arc surface to press the protective cover out of the charging port. Then, the lifting push rod 481 continues to move down and stops when the clamp 485 reaches the position of the charging port. The driving push rod 486 then controls the clamp 485 to slide out of the square hole, and causes the charging connector to be inserted into the charging port of the drone. After charging is completed, the driving push rod 486 can pull out the charging connector and reset it. The lifting push rod 481 resets with the paddle 484, and the paddle 484 pushes the protective cover up, finally closing the protective cover.

[0038] Meanwhile, during charging, the pressure rod 488 directly presses against the surface of the drone. Because it slides against the side frame 487 and can be reset by the elastic element 489, it does not affect the operation of the charging mechanism. When the drone needs to be turned on or off, the lifting push rod 481 sends the pressure rod 488 to the switch button. Then, the telescopic push rod 482 controls the pressure rod 488 to approach the switch button. The pressure rod 488, under pressure, presses the drone button. The telescopic push rod 482 can be programmed to control the pressure rod 488 to indirectly press the switch button, thus satisfying the drone's power-on method of short-press and long-press combination buttons. The remaining structure is the same as in Embodiment 2.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
