Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, specifically a rapid loading and unloading device for UAV emergency rescue. Background Technology

[0002] With the development, application and gradual promotion of drone technology, drones are being used more and more widely in the field of emergency rescue. Compared with ground transportation that relies on manpower and vehicles, drone logistics has the advantages of convenience and speed, especially in transporting urgently needed items in congested cities and remote and rugged mountainous areas. Compared with land transportation, it can greatly save manpower and time costs.

[0003] However, when loading and unloading goods by drones, the low height of the drones often requires operators to squat or even lie down to load the goods into the drone's pod or onto the hook below the drone, which is time-consuming, labor-intensive, and inconvenient.

[0004] Therefore, this application provides a rapid loading and unloading device for drone emergency rescue to solve the above problems. Utility Model Content

[0005] This application provides a drone emergency rescue mounting and rapid loading and unloading device, which aims to solve the problems mentioned in the background art, such as the fact that when manually loading and unloading goods with existing drones, the operators often need to adopt a semi-squatting or even semi-lying posture to load the goods into the drone pod or hang them on the hook under the drone, which is time-consuming, labor-intensive and inconvenient.

[0006] To achieve the above objectives, this application provides the following technical solution: a rapid loading and unloading device for emergency rescue payloads on a drone, applied to the drone body and fixedly installed at the bottom of the drone body for supporting the landing gear; To facilitate rapid loading and unloading of goods: a loading assembly for loading materials is set at the bottom of the fuselage, and a placement assembly is fixedly set inside the landing gear for supporting the loading assembly; the placement assembly includes a placement strip set on the side of the loading assembly for mounting the loading assembly, a connecting rod fixedly connected to one side of the placement strip for connecting with the landing gear, and a limiting member inserted through one end of the placement strip for restricting the movement of the loading assembly. When emergency rescue supplies need to be placed, the lever is pulled away from the connecting rod, causing the lever to move the limiting block out of the slot via the baffle. Then, the locking frame is pulled to move the loading box out of the landing gear, facilitating the loading and unloading of supplies. After the supplies are loaded and unloaded, the loading box is pushed towards the landing gear, causing the loading box to move synchronously with the locking frame. When the locking frame no longer presses against the limiting block, the limiting block, under the action of the spring's restoring force, pushes itself through the first through hole, thereby restricting the movement of the locking frame. This ensures that the loading assembly will not fall off during the flight of the aircraft, enabling rapid loading and unloading of supplies. When the aircraft cannot land, the push rod output end can be extended. The push rod output end drives the connecting block, causing the bottom plate at the bottom of the loading box to move, thereby opening the bottom of the loading box for airdropping supplies.

[0007] Preferably, to facilitate the installation of the loading assembly: the bottom end of the body is fixedly connected to the top end of the landing gear; a slot for the loading assembly to pass through is provided on the side of the placement strip away from the connecting rod; the outer wall of the placement strip is fixedly connected to the side of the connecting rod facing the placement strip; and the end of the connecting rod is fixedly connected to the outer wall of the landing gear. By inserting the snap-fit ​​frame into the slot, the loading assembly and the landing gear can be quickly installed, thereby facilitating the rapid loading and unloading of materials.

[0008] Preferably, to prevent the loading component from falling off: one end of the placement strip and connecting rod has a cavity for installing the limiting member, and the two ends of the inner wall of the cavity have a first through hole and a second through hole, respectively. The limiting member includes a limiting block inserted inside the first through hole to limit the movement of the loading component, a baffle fixedly connected to one end of the limiting block to limit the movement of the limiting block, a spring disposed on the side of the baffle away from the limiting block to push the baffle, and a pull rod inserted inside the second through hole to drive the baffle to move. The limiting block can prevent the locking frame from moving out of the slot, so that the loading component will not slip out of the slot when the aircraft takes off.

[0009] Preferably, the horizontal cross-section of the limiting block is a right-angled triangle.

[0010] Preferably, to facilitate loading of materials: the loading assembly includes a loading box disposed at the bottom of the machine body for loading items, a base plate disposed at the bottom of the loading box for opening and closing the bottom of the loading box, and a snap-fit ​​frame fixedly connected to the top of the loading box for inserting into the slot. By loading materials into the loading box, the materials are placed in combination with the loading box and the base plate.

[0011] Preferably, for guiding the movement of the base plate: the outer wall of the loading box is provided with a driving component for driving the movement of the base plate, and limiting plates for restricting the movement of the base plate are fixedly connected to both sides of the outer wall of the loading box. The limiting plates restrict the movement of the base plate, ensuring that the base plate can only move in a straight line.

[0012] Preferably, to drive the base plate to move: the driving component includes a connecting block fixedly connected to one end of the base plate for driving the base plate to move, a push rod disposed at one end of the connecting block for driving the connecting block to move, and a mounting bracket fixedly connected to the top of the push rod for mounting the push rod. One side of the mounting bracket is fixedly connected to the outer wall of the loading box. By extending or retracting the output end of the push rod, the connecting block is driven to move synchronously, thereby driving the base plate to move, opening the bottom of the loading box, and allowing the materials inside the loading box to be airdropped.

[0013] This application, through the design of loading components, placement components, driving components, and limiting trays, allows for easy loading and unloading of materials. By pulling the lever away from the connecting rod, the limiting block is moved out of the slot, and then the locking frame is pulled, causing the loading box to move out of the landing gear. After loading and unloading, the loading box is pushed towards the landing gear, causing the loading box to move synchronously with the locking frame. When the locking frame no longer presses against the limiting block, a spring pushes the limiting block to insert into the first through hole, limiting the movement of the locking frame and enabling rapid loading and unloading of materials. When the machine cannot land, the output end of the control push rod extends, driving the connecting block to move the bottom plate at the bottom of the loading box, thereby opening the bottom of the loading box for airdropping materials.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] This embodiment provides a rapid loading and unloading device for drone emergency rescue payloads, such as... Figure 1-6 As shown, the loading and unloading device is applied to the fuselage 1 and fixedly installed at the bottom of the fuselage 1 to support the landing gear 2 of the fuselage 1; To facilitate quick loading and unloading of goods: a loading assembly 3 is set at the bottom of the body 1 for loading materials, and a placement assembly 4 is fixedly set inside the landing gear 2 for supporting the loading assembly 3; the placement assembly 4 includes a placement strip 41 set on the side of the loading assembly 3 for mounting the loading assembly 3, a connecting rod 42 fixedly connected to one side of the placement strip 41 for connecting with the landing gear 2, and a limiting member inserted through one end of the placement strip 41 for restricting the movement of the loading assembly 3. When it is necessary to place emergency rescue items, pull the lever 46 away from the connecting rod 42. The lever 46 moves the limiting block 43 out of the slot through the baffle 44. Then pull the locking frame 33 to move the loading box 31 out of the landing gear 2, which facilitates the loading and unloading of materials. After the materials are loaded and unloaded, push the loading box 31 towards the landing gear 2. The loading box 31 moves the locking frame 33 synchronously. When the locking frame 33 no longer squeezes the limiting block 43, the limiting block 43 is pushed into the first through hole by the restoring force of the spring 45, thereby restricting the movement of the locking frame 33. This ensures that the loading component 3 will not fall off when the aircraft 1 is in flight, and realizes the rapid loading and unloading of materials. When the aircraft 1 cannot land, the output end of the push rod 52 can be extended by controlling the push rod 52. The output end of the push rod 52 drives the connecting block 51 to move the bottom plate 32 at the bottom of the loading box 31, thereby opening the bottom of the loading box 31 for airdrop of materials.

[0018] Furthermore, the fuselage 1 and landing gear 2 constitute the existing unmanned aerial vehicle, which belongs to the existing technology in the existing field. Two landing gears 2 are symmetrically arranged, located on both sides of the bottom end of the fuselage 1 respectively. The landing gear 2 is supported by metal rods.

[0019] Specifically, to facilitate the installation of the loading assembly 3: the bottom end of the fuselage 1 is fixedly connected to the top end of the landing gear 2. A slot for the loading assembly 3 to pass through is provided on the side of the placement strip 41 away from the connecting rod 42. The outer wall of the placement strip 41 is fixedly connected to the side of the connecting rod 42 facing the placement strip 41, and the end of the connecting rod 42 is fixedly connected to the outer wall of the landing gear 2. By inserting the snap-fit ​​frame 33 into the slot, the loading assembly 3 and the landing gear 2 can be quickly installed, facilitating rapid loading and unloading of materials. The height of the slot matches the height of the snap-fit ​​frame 33, the number of placement assemblies 4 corresponds to the number of landing gear 2 units, the connecting rod 42 is positioned between the two metal rods of the landing gear 2, both ends of the connecting rod 42 are welded and fixed to the outer wall of the metal rod of the landing gear 2, and the connecting rod 42 is welded and fixed to the placement strip 41. The length of the placement strip 41 is less than the straight-line distance between the two vertical metal rods of the landing gear 2. Two placement assemblies 4 are symmetrically positioned on both sides of the snap-fit ​​frame 33, providing support for the snap-fit ​​frame 33.

[0020] More specifically, to prevent the loading assembly 3 from falling off: one end of the placement strip 41 and the connecting rod 42 is provided with a cavity for installing the limiting component. The inner walls of the cavity are respectively provided with a first through hole and a second through hole at both ends. The limiting component includes a limiting block 43 inserted inside the first through hole to restrict the movement of the loading assembly 3, a baffle 44 fixedly connected to one end of the limiting block 43 to restrict its movement, a spring 45 located on the side of the baffle 44 away from the limiting block 43 to push the baffle 44, and a pull rod 46 inserted inside the second through hole to move the baffle 44. The horizontal cross-section of the limiting block 43 is a right-angled triangle. The limiting block 43 prevents the locking frame 33 from moving out of the slot, thus preventing the loading assembly 3 from slipping out of the slot when the aircraft 1 takes off. The first through hole is adapted to the size of the limiting block 43, and the second through hole is adapted to the size of the pull rod 46. The first through hole is located on the inner wall of the slot. The baffle 44 is welded and fixed to the limiting block 43. The size of the baffle 44 is 1.2 times the size of the first through hole. The baffle 44 and the spring 45 are both set in the cavity. The spring 45 is always in a compressed state in the cavity. The spring 45 is sleeved on the outside of the pull rod 46. The contact part between the pull rod 46 and the baffle 44 is welded and fixed. Thus, by pulling the pull rod 46, the limiting block 43 is moved into the first through hole, and the snap-fit ​​frame 33 can be moved out of the slot, so that the loading assembly 3 can be moved out of the slot. Remove the landing gear 2 for quick loading and unloading of cargo. The inclined surface of the limiting block 43 faces away from the landing gear 2. When the loading assembly 3 is installed, the snap-fit ​​frame 33 is inserted into the slot. The outer wall of the snap-fit ​​frame 33 will press against the inclined surface of the limiting block 43 until the snap-fit ​​frame 33 separates from the limiting block 43. The restoring force of the spring 45 will push the baffle 44 to make the limiting block 43 extend into the slot. The right-angled edge of the limiting block 43 contacts the outer wall of the snap-fit ​​frame 33, thereby restricting the movement of the snap-fit ​​frame 33. This allows the loading assembly 3 to be quickly installed inside the landing gear 2.

[0021] Specifically, to facilitate the loading of materials: the loading assembly 3 includes a loading box 31 located at the bottom of the body 1 for loading items, a base plate 32 located at the bottom of the loading box 31 for opening and closing the bottom of the loading box 31, and a snap-fit ​​frame 33 fixedly connected to the top of the loading box 31 for insertion into the slot. By loading materials into the loading box 31, the materials are placed in combination with the base plate 32. The top of the loading box 31 is welded and fixed to the bottom of the snap-fit ​​frame 33. The snap-fit ​​frame 33 is a rectangular frame. The loading box 31 is surrounded by four vertical plates, and the horizontal cross-section of the loading box 31 is rectangular. The size of the loading box 31 is smaller than the size of the snap-fit ​​frame 33.

[0022] More specifically, for guiding the movement of the base plate 32: the outer wall of the loading box 31 is provided with a driving component 5 for driving the movement of the base plate 32, and two limiting plates 6 for restricting the movement of the base plate 32 are fixedly connected to both sides of the outer wall of the loading box 31. The movement of the base plate 32 is restricted by the limiting plates 6, ensuring that the base plate 32 can only move in a straight line. Two limiting plates 6 are symmetrically arranged, the vertical cross-section of the limiting plates 6 is L-shaped, the vertical outer wall of the limiting plates 6 is welded and fixed to the outer wall of the loading box 31, the distance between the horizontal top of the limiting plates 6 and the bottom of the loading box 31 corresponds to the thickness of the base plate 32, two base plates 32 are symmetrically arranged, the total size of the two base plates 32 corresponds to the outer perimeter size of the bottom of the loading box 31, and the total width of the loading box 31 and the driving component 5 is less than the distance between the two vertical metal rods of the landing gear 2.

[0023] Furthermore, to drive the base plate 32 to move: the driving component 5 includes a connecting block 51 fixedly connected to one end of the base plate 32 for driving the base plate 32 to move, a push rod 52 disposed at one end of the connecting block 51 for driving the connecting block 51 to move, and a mounting bracket 53 fixedly connected to the top of the push rod 52 for mounting the push rod 52. One side of the mounting bracket 53 is fixedly connected to the outer wall of the loading box 31. By extending and retracting the output end of the push rod 52, the connecting block 51 is driven to move synchronously, thereby driving the base plate 32 to move, opening the bottom end of the loading box 31, and allowing the materials inside the loading box 31 to be airdropped. Two sets of drive components 5 are located at both ends on one side of the loading box 31, thereby driving the two base plates 32 to move and open the bottom end of the loading box 31. The mounting bracket 53 is welded and fixed to the outer wall of the loading box 31. The mounting bracket 53 is bolted to the push rod 52. The push rod 52 is an existing electrically controlled multi-stage telescopic rod. The output end of the push rod 52 is bolted to one end of the connecting block 51. The other end of the connecting block 51 is bolted to one end of the base plate 32.

[0024] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
