[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV for small-item logistics transportation with an electromagnetically locked cargo compartment. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. With the development of UAV technology, UAVs can also carry other heavy objects, and there is a great demand for the transportation of relief supplies in extreme weather such as earthquakes, mudslides, and blizzards.

[0003] The existing patent publication number CN222005346U, entitled "Automatic Opening and Closing Device for Cargo Dropping by Unmanned Aerial Vehicles," proposes a device that is simple to control. When the electromagnetic lock is energized, the latch extends to lock the hatch, and when the latch retracts into the electromagnetic lock, the hatch is opened to drop cargo. When not energized, the hatch can be opened directly by pulling the tail lever of the electromagnetic lock without damaging the servo motor, making it convenient to use.

[0004] However, the drone disclosed in the aforementioned patent needs to deliver goods into the cargo compartment through the bottom of the cargo compartment before closing the door. This process requires manual support of the goods to prevent them from falling out of the cargo compartment, making it inconvenient to put the goods into the cargo compartment. Therefore, it is necessary to propose a drone for small-item logistics transportation with an electromagnetically locked cargo compartment to solve the above problems. Utility Model Content

In the early stage of this process, the goods need to be supported by a person to prevent them from falling out of the bottom of the cargo compartment, which makes it inconvenient to put the goods into the cargo compartment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drone for small-item logistics transportation with an electromagnetically locked cargo compartment, comprising a drone body, a frame fixedly installed at the bottom of the drone body, a cargo compartment installed on the inner wall of the top of the frame via an installation component, a lifting frame slidably installed inside the cargo compartment via a lifting component, doors rotatably installed at the left and right ends of the bottom of the lifting frame via a rotating component, an electromagnetic lock fixedly installed at the middle of the front and rear ends of the lifting frame via an installation plate, a locking tongue slidably installed inside the electromagnetic lock, and a slot opened inside the cargo compartment, with the locking tongue engaging inside the slot;

[0007] The lifting assembly includes four sleeve rods, which are fixedly installed at the four corners inside the cargo compartment. A telescopic rod is slidably installed inside the sleeve rod via a power assembly, and the telescopic rod is fixedly installed on the inner wall of the lifting frame.

[0008] Preferably, the rotating assembly includes four support plates, which are fixedly disposed at the four corners of the lifting frame. A fixed shaft is fixedly disposed between two support plates on the same side. Two symmetrically distributed rotating blocks are rotatably disposed on the outer ring of the fixed shaft. A first spring is fixedly connected between the rotating blocks and the corresponding support plates. The first spring is movably sleeved on the outer ring of the fixed shaft. The hatch and the rotating blocks are fixedly connected.

[0009] Preferably, a fixing block is fixedly provided in the middle of the fixing shaft, the fixing block is fixedly connected to the lifting frame, and a second spring is fixedly connected between the two sides of the fixing block and the two rotating blocks respectively, and the second spring is movably sleeved on the outer ring of the fixing shaft.

[0010] Preferably, a limiting frame is fixedly provided on the outer side of the lifting frame, and the upper surface of the limiting frame is in contact with the lower surface of the cargo hold.

[0011] Preferably, the power assembly includes a motor, which is fixedly mounted in the middle of the top of the cargo hold. A power cavity is formed inside the structural layer of the top of the cargo hold. The output end of the motor extends movably into the power cavity and is fixedly connected to a first gear. A second gear is rotatably mounted at each of the four corners of the power cavity. The first gear and the second gear mesh with each other. A screw is fixedly connected to the bottom of the second gear. A threaded hole is provided inside the telescopic rod, and the screw and the threaded hole are threadedly connected.

[0012] Preferably, in the initial state, the hatch is in a horizontal position, and the latch is engaged inside two interconnected slots.

[0013] Preferably, the mounting assembly includes two symmetrically distributed steel plates, which are fixedly mounted on the top of the cargo hold and are fixedly connected to the inner wall of the top of the frame by bolts.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the process of using this utility model, the materials are placed inside the lifting frame, the motor is started, the first gear and the second gear are driven to rotate, which in turn drives the screw to rotate, thereby causing the telescopic rod and the lifting frame to move upward until the upper surface of the limit frame and the lower surface of the cargo compartment are in contact, thus making it easier to put the materials into the cargo compartment. This solves the problem that in the process of using existing drones for small-item logistics transportation, materials need to be sent into the cargo compartment through the bottom of the cargo compartment and then the door is closed. In the early stage of this process, the materials need to be supported by people to prevent them from falling out of the bottom of the cargo compartment, which makes it inconvenient to put the materials into the cargo compartment.

[0016] 2. When the goods arrive at the designated location, the electromagnetic lock is energized, the latch retracts, and the restriction on the slot is lifted. Under the weight of the goods, the two hatches rotate around the central axis of the two fixed shafts, opening the bottom of the lifting frame and allowing the goods to be dropped smoothly. At this time, the second spring and the first spring are twisted and deformed. After the goods are dropped, the second spring and the first spring return to their original deformation, causing the two hatches to rotate and reset. After the electromagnetic lock is de-energized, the latch extends and engages with the slot, locking the two hatches and improving the practicality of the lifting device.

[0017] 3. The installation of two steel plates facilitates the disassembly and installation of the cargo hold, thereby making it easier to maintain and repair the cargo hold and improving the practicality of the equipment. Attached Figure Description

[0024] 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 without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-5 The drone shown is a small-item logistics transport drone with an electromagnetically locked cargo compartment. It includes a drone body 1, a frame 2 fixedly mounted on the bottom of the drone body 1, a cargo compartment 4 mounted on the inner wall of the top of the frame 2 via an installation component, a lifting frame 5 slidably mounted inside the cargo compartment 4 via a lifting component, a limit frame 12 fixedly mounted on the outer side of the lifting frame 5, a door 15 rotatably mounted on both the left and right ends of the bottom of the lifting frame 5 via a rotating component, an electromagnetic lock 21 fixedly mounted on the middle of the front and rear ends of the lifting frame 5 via an installation plate, a locking tongue 20 slidably mounted inside the electromagnetic lock 21, and a slot 16 opened inside the door 15, with the locking tongue 20 engaging inside the slot 16.

[0026] The lifting assembly includes four sleeve rods 6, which are fixedly installed at the four corners inside the cargo compartment 4. A telescopic rod 7 is slidably installed inside the sleeve rod 6 via a power assembly, and the telescopic rod 7 is fixedly installed on the inner wall of the lifting frame 5.

[0027] The power assembly includes a motor 8, which is fixedly installed in the middle of the top of the cargo compartment 4. A power cavity is opened inside the structural layer of the top of the cargo compartment 4. The output end of the motor 8 extends into the power cavity and is fixedly connected to a first gear 9. A second gear 10 is rotatably installed at each of the four corners of the power cavity. The first gear 9 and the second gear 10 mesh with each other. A screw 11 is fixedly connected to the bottom of the second gear 10. A threaded hole is provided inside the telescopic rod 7. The screw 11 and the threaded hole are threadedly connected.

[0028] Specifically, in the initial state of use, the door 15 is in a horizontal position, and the locking tongue 20 is engaged with the two interconnected slots 16, thereby closing the bottom of the lifting frame 5. The materials are placed inside the lifting frame 5, and the motor 8 is started, driving the first gear 9 and the second gear 10 to rotate, which in turn drives the screw 11 to rotate, thereby causing the telescopic rod 7 and the lifting frame 5 to move upward until the upper surface of the limiting frame 12 and the lower surface of the cargo compartment 4 are in contact, thus facilitating the placement of materials into the cargo compartment 4. This solves the problem that in the use of existing drones for small-item logistics transportation, materials need to be sent into the cargo compartment 4 through the bottom of the cargo compartment 4 before the door 15 is closed. In the early stages of this process, the materials need to be manually supported to prevent them from falling out of the bottom of the cargo compartment 4, which makes it inconvenient to place the materials into the cargo compartment 4.

[0029] Furthermore, the rotating assembly includes support plates 13, and four support plates 13 are provided. The four support plates 13 are respectively fixedly installed at the four corners of the lifting frame 5. A fixed shaft 14 is fixedly installed between two support plates 13 on the same side. Two symmetrically distributed rotating blocks 17 are rotatably installed on the outer ring of the fixed shaft 14. A first spring 19 is fixedly connected between the rotating block 17 and the corresponding support plate 13. The first spring 19 is movably sleeved on the outer ring of the fixed shaft 14. The hatch 15 and the rotating block 17 are fixedly connected.

[0030] Furthermore, a fixing block 18 is fixedly installed in the middle of the fixing shaft 14. The fixing block 18 is fixedly connected to the lifting frame 5. A second spring is fixedly connected between the two sides of the fixing block 18 and the two rotating blocks 17 respectively. The second spring is movably sleeved on the outer ring of the fixing shaft 14.

[0031] Once the goods have been transported to the designated location, the electromagnetic lock 21 is energized, the locking tongue 20 retracts, and the restriction on the slot 16 is lifted. Under the weight of the goods, the two hatches 15 rotate around the central axis of the two fixed shafts 14, opening the bottom of the lifting frame 5 and allowing the goods to be loaded smoothly. At this time, the second spring and the first spring 19 undergo twisting deformation. After the goods are loaded, the second spring and the first spring 19 return to their original deformation, causing the two hatches 15 to rotate and reset. After the electromagnetic lock 21 is de-energized, the locking tongue 20 extends and engages with the inside of the slot 16, locking the two hatches 15 and improving the practicality of the lifting device.

[0032] Furthermore, the installation assembly includes two symmetrically distributed steel plates 3, which are fixedly installed on the top of the cargo hold 4. The steel plates 3 are fixedly connected to the inner wall of the top of the frame 2 by bolts. The arrangement of the two steel plates 3 facilitates the disassembly and installation of the cargo hold 4, thereby facilitating the maintenance and repair of the cargo hold 4 and improving the practicality of the device.

[0033] Working principle: In the initial state of use, the hatch 15 is in a horizontal position, and the locking tongue 20 is engaged with the two interconnected slots 16, thereby closing the bottom of the lifting frame 5. Materials are placed inside the lifting frame 5, and the motor 8 is started, driving the first gear 9 and the second gear 10 to rotate, which in turn drives the screw 11 to rotate. This causes the telescopic rod 7 and the lifting frame 5 to move upwards until the upper surface of the limiting frame 12 is in contact with the lower surface of the cargo hold 4, facilitating the placement of materials into the cargo hold 4. After transportation to the designated location... When the electromagnetic lock 21 is energized, the locking tongue 20 retracts, releasing the restriction on the slot 16. Under the weight of the materials, the two hatches 15 are pushed to rotate around the central axis of the two fixed shafts 14, opening the bottom of the lifting frame 5 and thus smoothly dropping the materials. At this time, the second spring and the first spring 19 undergo twisting deformation. After the materials are dropped, the second spring and the first spring 19 return to their deformation, causing the two hatches 15 to rotate and reset. After the electromagnetic lock 21 is de-energized, the locking tongue 20 extends and engages with the inside of the slot 16, locking the two hatches 15.

[0034] The wiring diagrams of the motor 8 and electromagnetic lock 21 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 8 and electromagnetic lock 21 will not be explained in detail.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
