DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0022] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0023] The utility model provides a device for automatically mounting and unloading cargo from a drone, such as Figures 1 to 3 As shown, it includes a sky hook assembly 1 and a positioning assembly 2. The positioning assembly 2 includes a guide frame 21. A hook 22 is provided on the guide frame 21. The sky hook assembly 1 includes a suspension rope 11, a mounting member 12, and a lifting member 13. The suspension rope 11 is fixedly connected to the mounting member 12. The lifting member 13 is rotatably matched with the mounting member 12. A power mechanism 14 for driving the mounting frame to rotate is provided in the mounting member 12. The power mechanism 14 is electrically connected to a remote controller. The lifting member 13 includes a mounting portion 131 and a lifting portion 132. The mounting portion 131 and the lifting portion 132 are perpendicular to each other.

[0024] By adopting the above technical solution, the drone can accurately mount or unload the cargo to the designated location, greatly reducing the safety risks during the operation and improving the accuracy of mounting and unloading, which can effectively improve the transportation efficiency. There is no need for staff to manually pick up and place the cargo, which is simple to operate, reduces labor costs, is safer and more practical.

[0025] In this embodiment, the power mechanism 14 is remotely controlled, and the operator can control the power mechanism 14 to drive the lifting and lowering member 13 to rotate at a safe distance to avoid direct exposure to potential dangers or risks. In other embodiments, a control signal can be sent to a receiver on the drone via a wireless remote controller to control the operation of the power mechanism 14, or a dedicated application can be developed to remotely control the power mechanism 14 via Bluetooth, Wi-Fi or a mobile data network, or a dedicated console can be set up at a fixed location to remotely control the power mechanism 14 via a wired or radio connection.

[0026] In this embodiment, a lifting ring 123 is provided on the mounting member 12, and the lifting rope 11 is entangled and knotted with the lifting ring 123, so as to fix the lifting rope 11 on the mounting member 12 and ensure the flexibility of the structure.

[0027] In this embodiment, the materials are towed with a rope loop, the positioning component 2 is installed on the ground, and the rope loop for mounting the materials is hung on the hook 22. The UAV determines the flight position through the positioning component 2, rotates the lifting and releasing component 13 so that the lifting and releasing component 13 is hooked to the rope loop and then rises to pull up the materials, completing the process of unmanned loading of materials. After the UAV flies to the unloading point, it descends in altitude, drives the power mechanism 14 again, and rotates the lifting and releasing component 13 in the opposite direction to make the rope loop fall off, completing the process of unloading materials by the UAV.

[0028] In this embodiment, the lifting and placing portion 132 is configured as a conical structure, and the diameter of the lifting and placing portion 132 decreases along the side away from the mounting portion 131. The guiding property of the conical structure can make it easier for the lifting and placing component 13 to hook onto the rope loop. The diameter of the lifting and placing portion 132 on the side close to the mounting portion 131 increases, which can provide a larger support area for the lifting and placing portion 132, thereby enhancing the stability of the mounting of the lifting and placing component 13, and can effectively prevent the goods from falling off or shaking during transportation.

[0029] In this embodiment, the power mechanism 14 includes a driving motor 141, a first bevel gear 142, and a second bevel gear 143. The first bevel gear 142 is linked to the driving end of the driving motor 141, and the first bevel gear 142 is meshed and linked with the second bevel gear 143. The second bevel gear 143 is fixedly connected with a transmission rod 144, and the transmission rod 144 is linked to the lifting and lowering member 13 to realize the rotational drive of the lifting and lowering member 13. In this embodiment, the remote control driving motor 141 is started, and its driving end drives the first bevel gear 142 to rotate. Since the first bevel gear 142 is meshed with the second bevel gear 143, the second bevel gear 143 will also start to rotate. Since the second bevel gear 143 is fixedly connected to the transmission rod 144, the transmission rod 144 will rotate following the rotation of the second bevel gear 143. The movement of the transmission rod 144 is transmitted to the lifting and lowering member 13 through the linkage connection, thereby driving the lifting and lowering member 13 to rotate with the transmission rod 144 as the center.

[0030] In this embodiment, the transmission rod 144 passes through the mounting member 12 , and a bearing 121 is provided on the inner wall of the mounting member 12 . The transmission rod 144 is fixedly connected to the mounting member 12 via the bearing 121 , which can make the transmission rod 144 more stable.

[0031] In this embodiment, a limiting member 1311 is provided on the side of the mounting portion 131 facing the mounting member 12, and a limiting groove 122 matching the limiting member 1311 is provided on the side wall of the mounting member 12. The limiting member 1311 and the limiting groove 122 are both arranged in an annular structure. The limiting member 1311 and the limiting groove 122 of the annular structure can ensure that the lifting and releasing member 13 will not deviate from a predetermined trajectory during the rotation process, thereby maintaining stable rotation, ensuring the stability and accuracy of the lifting and releasing member 13 during the rotation process, and can prevent the lifting and releasing member 13 from accidentally falling off during the rotation process, thereby ensuring the safety and reliability of the entire system.

[0032] In this embodiment, the central axes of the limit member 1311 and the transmission rod 144 coincide with each other, and the limit member 1311 and the lifting and releasing portion 132 are respectively located on the adjacent side end surfaces of the mounting portion 131, to ensure that the lifting and releasing portion 13 can remain stable during the rotation process and rotate within a predetermined angle range. The rotation angle range of the lifting and releasing portion 13 is 0-90°. During the material loading process, the lifting and releasing portion 13 needs to rotate from the initial position (0°) to the position hooked with the rope loop (usually 90° or close to 90°) in order to pull up the materials. During the material unloading process, the lifting and releasing portion 13 needs to rotate in the opposite direction, from the position hooked with the rope loop back to the initial position to release the materials.

[0033] In this embodiment, the guide frame 21 includes a guide rod 211, and the guide frame 21 includes two groups. The axes of the guide rods 211 on the two groups of guide frames 21 intersect, and the hooks 22 on the two groups of guide frames 21 are arranged opposite to each other. The axes of the two groups of guide rods 211 intersect to form an intersection, which is convenient for the drone to determine the position of the hook 22. The rope loop used to mount materials is hung on the hook 22, which is convenient for the lifting and releasing component 13 to hook up the rope loop.
