Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a target object release device and target object for a UAV. Background Technology
[0002] With the rapid development of drone technology, drones are increasingly being used in civilian, commercial, and military fields. Drones are frequently used in various scenarios such as aerial photography, agricultural plant protection, power line inspection, logistics delivery, and firefighting.
[0003] In the field of firefighting, drones primarily perform tasks such as carrying payloads and pinpoint fire suppression. Since the drone and the target object operate independently, after securing the drone to the target, it's necessary to manually connect the target's circuitry to the drone's circuitry. The circuitry is then disconnected just before the target object explodes, initiating its detonation countdown and ultimately extinguishing the fire. However, the current method of manually connecting the target's circuitry to the drone's circuitry is quite cumbersome. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a target object release device and a target object for a drone, so as to realize the automatic circuit connection between the target object and the drone after automatic attachment and the automatic disconnection of the fuse optical axis of the target object. The specific technical solution is as follows:

[0016] The outer wall of the fixed seat sleeve near one end of the shelf has a first flange extending radially. The fixed seat sleeve passes through the through hole, and the first flange abuts against the side of the mounting platform facing the shelf.
[0017] The inner wall of the fixing seat sleeve located at the opening has a second flange extending radially, and the magnet fixing seat abuts against the second flange.
[0018] In some embodiments of this application, the magnetic attraction component further includes:
[0019] A buffer spring, which passes through the through hole on the mounting platform and is fixedly connected at one end to the magnet mounting base;
[0020] A spring cover is fixedly installed on the side of the mounting platform facing the shelf and covers the buffer spring.
[0021] In some embodiments of this application, the lifting assembly includes a mounting platform, which is fixedly connected to the telescopic end;
[0022] The hook assembly includes:
[0023] The hook body is rotatably connected to the mounting platform via a rotating shaft. The hook body includes a limiting part, a connecting part, and a hook part that are connected in sequence. One end of the limiting part and the hook part are both located on the first side of the rotating shaft. The hook part is used to hook the fuse optical shaft of the target object.
[0024] A hook limiting member is fixed to the bottom of the shelf, located above the limiting part, and able to abut against the portion of the limiting part located on the first side of the rotation axis.
[0025] In some embodiments of this application, one end of the hook portion is connected to the connecting portion;
[0026] In the first state, the connecting part hangs vertically, and the other end of the hook part is tilted toward the shelf;
[0027] In the second state, the connecting part is tilted away from the shelf.
[0028] In some embodiments of this application, the lifting assembly further includes: a push rod fixing seat, which is fixed to the shelf; and an electric push rod, one end of which is connected to the push rod fixing seat and the other end away from the shelf is connected to the magnetic suction assembly.

[0033] This application also provides a target object, the target object including a second magnet capable of being magnetically connected to a first magnet in the target object release device of the UAV as described in any of the above embodiments, the second magnet being electrically connected to the target object.
[0034] Beneficial effects:
[0035] This utility model provides a target object release device and target object for a drone. A carrying rack is provided at the bottom of the drone, and a lifting assembly is fixed to the bottom of the carrying rack. When the target object is loaded onto the carrying assembly, the lifting assembly drives the magnetic suction assembly to rise and fall. When the magnetic suction assembly descends a sufficient distance to approach the target object, the first magnet of the magnetic suction assembly can magnetically connect with the second magnet on the target object. Since the first magnet is connected to the drone's circuitry and the second magnet is connected to the target object's circuitry, the circuitry of the drone and the target object can be connected through the magnetic connection of the first and second magnets. Furthermore, the lifting assembly controls the hook assembly to rise and fall vertically. When the telescopic end of the lifting assembly is at the target position, the telescopic end is in the extended state. At this time, the hook assembly descends to its lowest position and can hook onto the fuse shaft of the target object. Then, the lifting assembly controls the hook assembly to rise vertically, allowing the hook assembly to break the fuse shaft of the target object.
[0036] Specifically, when the drone lands at the designated location on the drone landing platform, it uses its cargo-carrying component to grab the target object, automatically attaching the drone to the target. At this point, the lifting component controls the magnetic attraction component to descend vertically until the first magnet magnetically connects with the second magnet on the target object, automatically connecting the drone's circuitry to the target object's circuitry. Simultaneously, the hook component engages the fuse optical shaft on the target object. Under the control of the lifting component, the hook component and the magnetic attraction component work together, with the hook component 5 breaking the fuse optical shaft, causing it to detach from the target object's fixing block. The first and second magnets then separate under gravity. When the fuse optical shaft and circuit connection are simultaneously broken, the target object enters a countdown to detonation. When the drone drops the bomb, the target object falls freely from the drone. Under gravity, the first and second magnets separate, disconnecting the drone's circuitry from the target object's circuitry, causing the target object to enter a countdown to detonation.
[0037] Compared to existing technologies where the drone and target object are fixed together but still require manual connection of their circuits, the drone provided in this application utilizes a lifting assembly to control the lifting of a first magnet, thereby achieving automatic circuit connection between the target object and the drone after automatic mounting. Furthermore, this application uses only a single power source to complete multiple complex movements, including opening and closing the circuits between the drone and the target object, and breaking the circuit of the target object's fuse optical axis, achieving a flexible connection between the target object and the drone, significantly reducing the drone's weight and cost.
[0038] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art based on this application are within the protection scope of the present utility model.
[0057] This application provides a target object release device for a drone, such as... Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the connection between the target object release device and the target object provided in this application; Figure 2A schematic diagram of the structure connecting the target object release device provided in this application to the target object (the drone return platform is not shown). The target object release device of the drone includes: a carrier frame 1, located at the bottom of the drone body; a carrier assembly 2, fixed to the bottom of the carrier frame 1, used for loading or releasing the target object 7; a lifting assembly 3, located below the carrier frame 1, with its fixed end fixed to the bottom of the carrier frame 1 and its telescopic end capable of extending and retracting in the vertical direction; a magnetic suction assembly 4, connected to the telescopic end of the lifting assembly 3, including a first magnet 41 connected to the circuit of the drone, the first magnet 41 being able to magnetically connect with a second magnet 71 on the target object 7 that is connected to the circuit of the target object 7; and a hook assembly 5, connected to the telescopic end of the lifting assembly 3, capable of hooking the fuse optical shaft 72 of the target object 7 when the telescopic end is in the target position.
[0058] In this embodiment, a carrying rack 1 is provided at the bottom of the drone, and the lifting assembly 3 is fixed to the bottom of the carrying rack 1. When the drone's carrying assembly 2 loads the target object 7, the lifting assembly 3 drives the magnetic suction assembly 4 to rise and fall. When the magnetic suction assembly descends a sufficient distance to approach the target object 7, the first magnet 41 of the magnetic suction assembly 4 can magnetically connect with the second magnet 71 on the target object 7. Since the first magnet 41 is connected to the drone's circuitry and the second magnet 71 is connected to the target object 7's circuitry, the circuitry of the drone and the target object 7 can achieve a circuit through the magnetic connection of the first magnet 41 and the second magnet 71. Furthermore, the lifting assembly 3 controls the hook assembly 5 to rise and fall vertically. When the telescopic end of the lifting assembly is at the target position, the telescopic end is in the extended state. At this time, the hook assembly 5 descends to its lowest position and can hook with the fuse optical shaft 72 of the target object 7. At this time, the lifting assembly 3 controls the hook assembly 5 to rise vertically, so that the hook assembly 5 can break the fuse optical shaft 72 of the target object 7.
[0059] For details, see Figures 1 to 3 , Figure 3 for Figure 1The diagram shows the structure of the target object release device. When the drone lands at the designated position on the drone return platform 8, the drone uses the carrying component 2 to grab the target object 7, automatically attaching the drone to the target object 7. At this time, the lifting component 3 controls the magnetic suction component 4 to descend vertically until the first magnet 41 magnetically connects with the second magnet 71 of the target object 7, achieving automatic connection between the drone's circuitry and the target object 7's circuitry. Simultaneously, the hook component 5 hooks the fuse optical shaft 72 of the target object 7. Under the control of the lifting component 3, the hook component 5 and the magnetic suction component 4 work together to pull the fuse optical shaft 72 off, causing it to detach from the fixing block of the target object 7. The first magnet 41 and the second magnet 71 separate under gravity. When the fuse optical shaft 72 is simultaneously disconnected from the circuit, the target object 7 can enter the explosion countdown. When the drone drops the bomb, the target object 7 falls freely from the drone. Under the influence of gravity, the first magnet 41 separates from the second magnet 71, disconnecting the drone circuit from the target object 7 circuit, causing the target object 7 to enter a countdown in preparation for explosion.
[0060] Compared to existing technologies where the drone and target object 7 are fixed together but still require manual connection of their circuits, the drone provided in this application utilizes a lifting assembly 3 to control the lifting of the first magnet 41, thereby achieving automatic circuit connection between the target object 7 and the drone after automatic mounting. Furthermore, this application uses only a single power source to complete multiple complex movements, including the opening and closing of the drone's circuit and the target object 7's circuit, as well as the breaking of the fuse optical axis 72 of the target object 7, achieving a flexible connection between the target object 7 and the drone, significantly reducing the drone's weight and cost.
[0061] In some exemplary embodiments, the target object 7 can be a fire extinguishing bomb.
[0062] In some exemplary embodiments, one of the first magnet 41 and the second magnet 71 has a ring-shaped layout, that is, it has four copper rings nested sequentially from the center to the edge, and the other has four pins (micro connectors). When the first magnet 41 and the second magnet 71 are magnetically connected, the four pins can communicate with the four copper rings one by one. Furthermore, both the first magnet 41 and the second magnet 71 have pins on their back sides, which can be connected to their respective circuits.
[0063] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the lifting assembly 3 includes: a push rod fixing seat 32, which is fixed to the shelf 1; and an electric push rod 33, one end of which is connected to the push rod fixing seat 32, and the other end away from the shelf 1 is connected to the magnetic suction assembly 4.
[0064] In this embodiment, the electric push rod 33 is installed on the shelf 1 using the push rod fixing seat 32, so that the magnetic suction assembly 4 can move up and down in the vertical direction under the drive of the electric push rod 33.
[0065] In some implementations of this application, such as Figures 2 to 4 As shown, Figure 4 This is a cross-sectional view of the magnetic suction assembly of the target object release device provided in this application. The lifting assembly 3 includes a mounting platform 31, which is fixedly connected to the telescopic end; the magnetic suction assembly 4 further includes: a fixed seat sleeve 42, which is located on the side of the mounting platform 31 away from the shelf 1, and one end of the fixed seat sleeve 42 away from the shelf 1 has an opening; and a magnet fixing seat 43, which is located inside the fixed seat sleeve 42, and one end of which is away from the shelf 1 is connected to the first magnet 41 through the opening.
[0066] In this embodiment, the telescopic end of the lifting assembly 3 can drive the mounting platform 31 to rise and fall vertically. A fixed base sleeve 42 is mounted on the mounting platform 31, and a magnetic fixing seat 43 is located within the fixed base sleeve 42. The magnetic fixing seat 43 can be a male connector, and the first magnet 41 can be a female connector. They are fixedly connected by magnetic attraction, and the magnetic force between them is greater than the magnetic force between the first magnet 41 and the second magnet 71. Thus, when the target object 7 falls freely, the first magnet 41 and the second magnet 71 will separate under gravity, but the first magnet 41 will not separate from the magnetic fixing seat 43. This embodiment uses the magnetic fixing seat 43 to fix the first magnet 41 to the mounting platform 31, allowing the first magnet 41 to rise and fall vertically under the drive of the lifting assembly 3. Furthermore, the magnetic fixing seat 43 can move vertically within the fixed base sleeve 42, allowing the first magnet 41 to move vertically when magnetically connected to the second magnet 71, thus providing a buffer for the connection between the two.
[0067] In some implementations of this application, such as Figure 4 As shown, the mounting platform 31 has a through hole extending along the thickness direction; the outer wall of the fixing sleeve 42 near one end of the shelf 1 has a first flange 421 extending radially, the fixing sleeve 42 passes through the through hole, and the first flange 421 abuts against the side of the mounting platform 31 facing the shelf 1; the inner wall of the fixing sleeve 42 located at the opening has a second flange 422 extending radially, and the magnet fixing seat 43 abuts against the second flange 422.
[0068] In this embodiment, the fixing sleeve 42 abuts against the mounting platform 31 via a first flange 421 on its outer side wall, allowing it to be mounted on the mounting platform 31 and thus able to move vertically under the drive of the lifting assembly 3. The magnet fixing seat 43 also has a flange on its periphery, with the side of the flange facing the opening of the fixing sleeve 42 abutting against a second flange 422 on the inner side wall of the fixing sleeve 42. This restricts the vertical range of motion of the magnet fixing seat 43, ensuring that it will not detach from the fixing sleeve 42.
[0069] In some exemplary embodiments, the magnet holder 43 may also be cylindrical, with a diameter that is the same as the inner diameter of the portion of the holder sleeve 42 excluding the second flange 422, so that the edge of the magnet holder 43 facing the opening can directly abut against the second flange 422.
[0070] In some implementations of this application, such as Figure 4 As shown, the magnetic suction assembly 4 also includes: a buffer spring 44, which passes through a through hole in the mounting platform 31 and is fixedly connected at one end to the magnet fixing seat 43; and a spring cover 45, which is fixedly installed on the side of the mounting platform 31 facing the shelf 1 and covers the buffer spring 44.
[0071] In this embodiment, the buffer spring 44 passes through the through hole on the mounting platform 31 and extends into the interior of the fixing sleeve 42, where it is fixedly connected to the magnet fixing seat 43. Furthermore, a spring cover 45 is provided on the side of the mounting platform 31 facing the shelf 1, and the other end of the buffer spring 44 abuts against the top of the spring cover 45. When the first magnet 41 and the second magnet 71 are engaged, the first magnet 41 moves towards the shelf 1, causing the magnet fixing seat 43 to compress the buffer spring 44, accumulating elastic force for the buffer spring 44. When the first magnet 41 and the second magnet 71 are stably connected, the buffer spring 44 releases its elastic force, pushing the magnet fixing seat 43 to move the first magnet 41 away from the shelf 1, thus resetting the first magnet 41. In other words, in this embodiment, the first magnet 41 is adjusted by the buffer spring 44, allowing it to float vertically, thus achieving a buffering effect on the first magnet 41.
[0072] In some implementations of this application, such as Figure 3As shown, the lifting assembly 3 includes a mounting platform 31, which is fixedly connected to the telescopic end; the hook assembly 5 includes a hook body 51, which is rotatably connected to the mounting platform 31 via a rotating shaft 6; the hook body 51 includes a limiting part 511, a connecting part 512, and a hook part 513 connected in sequence; one end of the limiting part 511 and the hook part 513 are both located on the first side of the rotating shaft 6, and the hook part 513 is used to hook the fuse optical shaft 72 of the target object 7; the hook limiting member 52 is fixed to the bottom of the carrier 1, located above the limiting part 511, and can abut against the portion of the limiting part 511 located on the first side of the rotating shaft 6.
[0073] In this embodiment, the hook portion 513 of the hook body 51 can hook the fuse shaft 72 of the target object 7. When the hook body 51 breaks the fuse shaft 72 under the drive of the lifting assembly 3, the fuse shaft 72 falls off the target object 7 and may remain on the hook portion 513. At this time, the lifting assembly 3 drives the hook assembly 5 to continue rising until the hook limiting member 52 of the hook assembly 5 abuts against the limiting portion 511 of the hook body 51 to prevent the limiting portion 511 from rising further. Under the pressure of the hook limiting member 52, the hook body 51 rotates around the rotation axis 6, causing the fuse shaft 72 to automatically fall off the hook body 51, thereby preventing the fuse shaft 72 remaining on the hook body 51 from affecting the hook body 51's hooking of the fuse shaft 72 during the next loading process.
[0074] In some implementations of this application, such as Figure 3 As shown, one end of the hook portion 513 is connected to the connecting portion 512; in the first state, the connecting portion 512 hangs down in the vertical direction, and the other end of the hook portion 513 is tilted toward the shelf 1; in the second state, the connecting portion 512 is tilted away from the shelf 1.
[0075] In this embodiment, when the hook body 51 is in the first state, the limiting part 511 of the hook body 51 does not abut against the hook limiting member 52, and the connecting part 512 hangs naturally in the vertical direction under the action of gravity. At this time, the hook part 513 of the hook body 51 is tilted towards the shelf 1. The lifting component 3 controls the hook assembly 5 to descend, so that the bottom of the hook part 513 abuts against the fuse optical axis 72. At this time, the hook body 51 is in the second state. In the second state, as the hook assembly 5 continues to descend, the fuse optical axis 72 blocks the descent of the hook part 513, causing the hook body 51 to rotate around the rotation axis 6. The end of the connecting part 512 connected to the hook part 513 moves away from the fuse optical axis 72. At this time, the connecting part 512 gradually tilts away from the shelf 1, and the angle between the bottom side of the hook part 513 and the horizontal direction gradually decreases. Finally, the bottom of the hook portion 513 separates from the fuse optical axis 72, the lifting assembly 3 continues to descend, the entire hook portion 513 is located below the fuse optical axis 72, the hook body 51 resets under the action of gravity, so that the hook portion 513 can hook the fuse optical axis 72.
[0076] Specifically, when the drone lands, the lifting assembly 3 is in the zero position, that is, at the highest position. The limiting part 511 of the hook body 51 abuts against the hook limiting member 52. The hook body 51 is not connected to the fuse optical axis 72, and the first magnet 41 is not magnetically connected to the second magnet 71.
[0077] Once the target object 7 is in place, the drone's cargo-carrying component 2 loads the target object 7 onto the drone. At this point, see... Figure 5 , Figure 5 This is a schematic diagram of the hook assembly of the target object release device provided in this application in the first position. The lifting assembly 3 controls the magnetic suction assembly 4 and the hook body 51 to descend to the limit position, i.e., the lowest position. At this time, the first magnet 41 and the second magnet 71 are magnetically connected, so that the UAV circuit and the target object 7 circuit are connected. At the same time, during the descent, the hook body 51 gradually returns to the upright position from the tilted state under the action of gravity. When the bottom of the hook part 513 abuts against the fuse optical shaft 72, the hook body 51 gradually tilts until the hook body 51 hooks the fuse optical shaft 72.
[0078] After the drone takes off, the lifting assembly 3 changes from the extreme position to the intermediate position, that is, it is located between the zero position and the extreme position. See [link / reference needed]. Figure 6 , Figure 6This is a schematic diagram of the hook assembly of the target object release device provided in this application located in the second position. During this process, the lifting assembly 3 drives the mounting platform 31 to rise vertically. The second magnet 71, driven by the first magnet 41, detaches from the fixing block on the target object 7 and is only connected to the circuit of the target object 7 via a cable. Simultaneously, the hook body 51 breaks the fuse optical axis 72. Since the circuit of the drone and the circuit of the target object 7 remain connected, the target object 7 does not enter the countdown to explosion. When the bomb is released, the target object 7 falls freely from the drone. Under the action of gravity, the second magnet 71 separates from the first magnet 41. At this time, the fuse optical axis 72 of the target object 7 is broken, and its circuit is also disconnected from the drone circuit. The target object 7 then enters the countdown to detonate.
[0079] After the bomb is dropped, the lifting assembly 3 changes from the middle position to the zero position. See below. Figure 7 , Figure 7 This is a schematic diagram of the hook assembly of the target object release device provided in this application located in the third position. After the bomb is dropped, the lifting assembly 3 drives the installation platform 31 to continue rising and return to the zero position. During this process, the hook limiting member 52 abuts against the limiting part 511 of the hook body 51, causing the hook body 51 to rotate around the rotation axis 6, thereby causing any residual fuse optical shaft 72 on the hook body 51 to fall off, so as to avoid the residual fuse optical shaft 72 affecting the loading of the next target object 7.
[0080] In some implementations of this application, such as Figure 2 and Figure 3 As shown, the loading assembly 2 includes: a hook fixing seat 21, which is fixed to the bottom of the loading frame 1; and a hook 22, which is installed at the end of the hook fixing seat 21 away from the loading frame 1 and is a fixing device 73 capable of grabbing the target object 7.
[0081] In this embodiment, the grab hook 22 is fixed to the bottom of the carrier frame 1 by the grab hook fixing seat 21. When the drone lands, the grab hook 22 can grab the fixing device 73 of the target object 7, thereby loading the target object 7 onto the drone. The fixing device 73 can be a hanging lug on the target object 7.
[0082] In some implementations of this application, such as Figure 2 and Figure 3 As shown, the loading assembly 2 also includes an anti-sway device 23, which is fixedly connected to the grab hook 22 and is a fixing device 73 capable of clamping the target object 7.
[0083] In this embodiment, after the grab hook 22 grabs the target object 7, the anti-sway device 23 on the grab hook 22 is attached to the fixing device 73 of the target object 7, increasing the contact area between the load assembly 2 and the fixing device 73 of the target object 7. This effectively reduces the swaying of the target object 7 caused by the vibration of the drone, thereby improving the control accuracy of the drone and reducing the risk of drone crash. The anti-sway device 23 can be an anti-sway strip.
[0084] This application also provides a target object, such as Figure 1 and Figure 2 As shown, the target object 7 includes a second magnet 71 that can be magnetically connected to the first magnet 41 in the target object release device of any of the above embodiments of the UAV, and the second magnet 71 is electrically connected to the target object 7.
[0085] In this embodiment, the circuit of the target object 7 can be automatically connected to the circuit of the drone through the magnetic attraction between the second magnet 71 and the first magnet 41.
[0086] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
