Description

Technical Field

[0001] This utility model relates to the field of drone application technology, and more specifically, it relates to an auxiliary device for rapid loading and unloading of drone payloads. Background Technology

[0002] A drone is an unmanned aerial vehicle controlled by radio remote control equipment or its own program control device. With the booming development of the low-altitude economy, drones are increasingly used in logistics delivery, emergency rescue, and agricultural plant protection. Drones carrying logistics boxes are used for logistics delivery. The typical transportation mode is as follows: at the initial loading point, the goods to be carried are placed in a logistics box mounted on the drone. Then, the drone is operated to fly along a pre-set route to the receiving point, where it lands on the ground, and the goods are unloaded from the logistics box by designated personnel. Currently, the traditional connection methods for drone payloads are mainly bolted connections and frame-type fixation. Bolted connections typically use shackles and connecting bolts to connect to the suspended object. Although the structure is simple and the connection is stable, it cannot achieve quick deployment or retrieval of the suspended object, making it inconvenient to quickly remove the load. Frame-type fixation uses a frame structure with a guiding function. Although it improves installation accuracy to some extent, it still suffers from cumbersome operation and long processing time, making it inconvenient to quickly remove the load, requiring the entire payload to be disassembled for loading and unloading.

[0003] Therefore, to address the aforementioned issues, it is necessary to design an auxiliary device for the rapid loading and unloading of drone payloads. This device aims to eliminate the need for complex disassembly and assembly steps during loading and unloading, facilitate the retrieval and placement of delivery items, shorten the loading and unloading time of payloads and the placement and retrieval time of items, reduce the workload and operating time of operators, and improve the efficiency of logistics and distribution. Utility Model Content

The shell includes a receiving chamber that facilitates the movement of the push-pull box. A locking element corresponding to the opening of the receiving chamber is installed on the shell. A fixing head that cooperates with the locking element is installed at one end of the push-pull box. The locking element includes a movable locking rod movably connected to the shell, a fixed locking rod fixed to the shell, and a spring connecting the fixed locking rod and the movable locking rod. The fixed locking rod and the movable locking rod are V-shaped. The fixing head is movably connected to the push-pull box and cooperates with the movable locking rod.

[0006] Further configured, one end of the movable locking rod is rotatably connected to the housing via a bearing, the other end of the movable locking rod is fixed with an insert rod, one end of the fixed head has a positioning hole for inserting the insert rod, the other end of the fixed head is fixed with a slider arranged in a T-shape with the fixed head, the push-pull box has a sliding groove for sliding connection with the slider, and the slider is engaged with the sliding groove.

Detailed Implementation

[0019] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0020] An auxiliary device for rapid loading and unloading of payloads for unmanned aerial vehicles (UAVs) includes a chassis 100 mounted on the UAV fuselage. A payload box 200 for logistics and distribution is detachably connected to the chassis 100. The payload box 200 is drawer-type and includes a shell 1 and a push-pull box 2. The shell 1 includes a receiving chamber 3 for easy movement of the push-pull box 2. A locking member 4 corresponding to the opening of the receiving chamber 3 is installed on the shell 1. A fixing head 5 cooperating with the locking member 4 is installed at one end of the push-pull box 2. The locking member 4 includes a movable locking rod 41 movably connected to the shell 1, a fixed locking rod 42 fixed to the shell 1, and a spring 43 connecting the fixed locking rod 42 and the movable locking rod 41. The two ends of the spring 43 are fixedly connected to the fixed locking rod 42 and the movable locking rod 41, respectively. The fixed locking rod 42 and the movable locking rod 41 are arranged in a V-shape. The fixing head 5 is movably connected to the push-pull box 2. One end of the movable locking rod 41 is rotatably connected to the housing 1 via a bearing. The other end of the movable locking rod 41 is fixed with a plug rod 411. One end of the fixed head 5 has a positioning hole 51 for inserting into the plug rod 411. The other end of the fixed head 5 is fixed with a slider 52 arranged in a T-shape with the fixed head 5. The push-pull box 2 has a sliding groove 6 that is slidably connected to the slider 52, and the slider 52 is engaged with the sliding groove 6. The fixed locking rod 42 is provided with a mushroom-shaped positioning block 7. The plug rod 411 is fixed with a fixing rope 8 that cooperates with the positioning block 7. Both ends of the fixing rope 8 are fixed to the plug rod 411. The fixing rope 8 is sleeved on the positioning block 7 and is in a taut state. The fixed locking rod 42 has a guide groove 9 that is slidably connected to the positioning block 7 and a screw hole 10 that communicates with the guide groove 9. The fixed locking rod 42 is provided with a positioning screw 11 that is threadedly connected to the screw hole 10. The output end of the positioning screw 11 is rotatably connected to the positioning block 7 via a bearing.

[0021] Working principle: When loading and unloading logistics delivery items, the operator holds the handle 14 on the push-pull box 2 and pulls it outward. Since the push-pull box 2 moves within the receiving chamber 3 of the box shell 1, it can be smoothly pulled out of the box shell 1, making it convenient for the operator to take or place delivery items. After placing the items, push the push-pull box 2 back into the receiving chamber 3. Move the movable locking rod 41 so that its insert 411 aligns with the fixed head 5. At this time, the spring 43 is compressed, pushing the fixed head 5 to slide in the slide groove 6, so that the positioning hole 51 on the fixed head 5 aligns with the insert 411 on the movable locking rod 41. Release the movable locking rod 41 so that it abuts against the fixed head 5 under the action of the spring 43. At the same time, the insert 411 on the movable locking rod 41 inserts into the positioning hole 51 of the fixed head 5, thereby locking the load box 200. The operation is simple and convenient.

[0022] In the locked state, the insert 411 of the movable locking rod 41 is inserted into the positioning hole 51 of the fixed head 5. At this time, the fixing rope 8 is passed out from the positioning hole 51 under the action of the insert 411, and the fixing rope 8 is fitted onto the mushroom-shaped positioning block 7. The positioning screw 11 is rotated to push the positioning block 7 to move in the guide groove 9, so that the fixing rope 8 is in a taut state. This structure further fixes the position of the movable locking rod 41, thereby strengthening the connection between the push-pull box 2 and the box shell 1, and further locking the load box 200.

[0023] When unlocking is required, the operator reverses the positioning screw 11 to loosen the fixing rope 8, making it easier to remove the fixing rope 8 from the positioning block 7. Simultaneously, the operator moves the movable locking rod 41 to pull the insertion rod 411 out of the positioning hole 51. At this point, the fixing head 5 slides to the bottom of the slide groove 6, and the movable locking rod 41 returns to its initial position under the elastic action of the spring 43. The load box 200 is unlocked, and the push-pull box 2 can be pulled out to retrieve items. The operator does not need to spend a long time disassembling and reassembling the entire load box 200, making the loading and unloading process of delivered items simpler and faster, reducing the operator's workload and operating time. Ultimately, this achieves the ability to load and unload the load box 200 without complicated disassembly and assembly steps, facilitating the retrieval and placement of delivered items, shortening the loading and unloading time of the load box and the placement and retrieval time of the items, and improving the efficiency of logistics and distribution.

[0024] A magnet 12 is installed at the other end of the push-pull box 2, and a metal sheet 13 that is magnetically connected to the magnet 12 is installed on the inner wall of the receiving chamber 3.

[0025] Once the push-pull box 2 is pushed into the receiving chamber 3, the magnetic attraction between the magnet 12 and the metal plate 13 can serve as an auxiliary positioning and fixing method, helping the push-pull box 2 to be pushed into place more accurately, reducing problems such as insecure locking caused by positional deviation, and improving the reliability and stability of the entire device. At the same time, the magnetic connection between the magnet 12 and the metal plate 13 can further enhance the stability of the push-pull box 2 in the housing 1 during the flight of the drone, reducing the shaking of the push-pull box 2 caused by vibration or airflow.

[0026] A handle 14 is installed at one end of the push-pull box 2. The handle 14 provides a convenient gripping point for the operator, making it easier for the operator to pull out and push in the push-pull box 2, reducing the force required during operation, improving the convenience and comfort of operation, and reducing the labor intensity of the operator.

[0027] The payload box 200 is made of engineering plastics. Engineering plastics (such as nylon PA + carbon fiber filler) are lightweight. Using this material to make the payload box 200 can effectively reduce the weight of the drone, thereby improving the drone's payload capacity and endurance. This allows the drone to carry more logistics delivery items or complete delivery tasks over longer distances. In addition, engineering plastics have high strength and good corrosion resistance, enabling long-term use under different environmental conditions without easy damage, thus reducing the maintenance cost and replacement frequency of the payload box 200.

[0028] The housing 1 includes a first mounting hole 15, and the chassis 100 includes a second mounting hole 16 that mates with the first mounting hole 15. The first mounting hole 15 and the second mounting hole 16 are connected by bolts 17 to facilitate the mounting and fixing of the payload box 200 to the fuselage of the drone via the chassis 100. At the same time, it is convenient for the drone to remove the payload box 200 when it is not performing logistics delivery tasks.
