Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), specifically a convenient loading and unloading rack for cargo UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer.

The cargo frame is fixed to the drone's placement frame by bolts and limit blocks, so that the drone can transport the cargo frame. However, the installation and disassembly of the cargo frame and the drone placement frame are cumbersome. Based on this, in order to further improve work efficiency and facilitate the quick separation and connection of the cargo frame and the drone, this utility model proposes a convenient loading and unloading frame for cargo drones.

[0030] 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.

[0031] Please see Figures 1-4 In this embodiment of the present invention, a convenient loading and unloading rack for a cargo drone includes a drone body 1, a landing gear 2 fixed to the bottom of the drone body 1, a cargo frame 3 provided at the bottom of the landing gear 2, and a limiting mechanism 4 provided on the cargo frame 3.

[0032] The limiting mechanism 4 includes a limiting unit and a transmission unit;

[0033] The limiting unit is used to provide a limit for the connection between the landing gear 2 and the cargo frame 3;

[0034] The transmission unit is used to provide power for the movement of the limit unit;

[0035] The limiting unit includes a first fixed seat 401, a rotating rod 402, a second fixed seat 403, a limiting block 408, and a U-shaped block 409;

[0036] The first fixed seat 401 and the second fixed seat 403 are symmetrically fixed at the top of the cargo frame 3. The first fixed seat 401 is used to provide support for the rotation of the rotating rod 402, and the second fixed seat 403 is used to provide support for the axial movement of the limiting block 408.

[0037] The rotating rod 402 is rotatably connected to the top of the first fixed seat 401. The rotating rod 402 is used to limit the landing gear 2 that enters between the first fixed seat 401 and the second fixed seat 403.

[0038] The loop block 409 is fixed to the bottom of the rotating rod 402, and the limiting block 408 is used to cooperate with the loop block 409 to limit the rotation of the rotating rod 402;

[0039] The limiting block 408 is axially slidably installed inside the second fixed seat 403 and extends into the inner hole groove of the return block 409. The limiting block 408 is used to limit the rotation of the return block 409.

[0040] The transmission unit includes a pressing block 404, a spring 405, an L-shaped linkage rod 406, and a guide rod 407;

[0041] The pressing block 404 is vertically slidably installed inside the top of the cargo frame 3 and extends to the outside of the top of the cargo frame 3. The pressing block 404 is located in the middle area between the first fixed seat 401 and the second fixed seat 403. The pressing block 404 is used to synchronously drive the L-shaped linkage rod 406 to move.

[0042] The two ends of the spring 405 are respectively engaged with the bottom of the pressing block 404 and the inner wall of the cargo frame 3. The spring 405 is used to always provide the pressing block 404 with an upward squeezing force.

[0043] The L-shaped linkage rod 406 is fixed to the outer wall of the pressing block 404 and extends into the interior of the cargo frame 3. The L-shaped linkage rod 406 is used to synchronously drive the guide rod 407 to move vertically.

[0044] The guide rod 407 is fixed to the outer wall of the L-shaped linkage rod 406 and passes through the limiting block 408 to the other side of the limiting block 408. The guide rod 407 is used to give the limiting block 408 axial movement extrusion force.

[0045] In this embodiment: when the cargo frame 3 needs to be transported, the landing gear 2 is inserted between the first fixed seat 401 and the second fixed seat 403. At this time, the rotating rod 402 is in the open state. Then, the second fixed seat 403 is rotated so that the U-shaped block 409 at the end of the second fixed seat 403 moves to the inside of the end of the rotating rod 402. At this time, the pressing block 404 is always in contact with the bottom of the landing gear 2, so that the pressing block 404 is inside the cargo frame 3. When the end of the rotating rod 402 is aligned with the top of the second fixed seat 403, when the UAV body 1 is started to fly and ascend, the landing gear 2 moves with the upward movement of the UAV body 1. After the landing gear 2 moves, it no longer abuts against the top of the pressing block 404. As the spring 405 returns to its original position, the movement of the pressing block 404 synchronously drives the L-shaped linkage rod 406 to move upward. This causes the L-shaped linkage rod 406 to synchronously drive the guide rod 407 to move along the guide groove inside the limiting block 408, giving the limiting block 408 an axial moving thrust. This causes the end of the limiting block 408 to move towards the slot of the return block 409 until the limiting block 408 and the return block 409 are connected. Then, the return block 409 will be limited by the limiting block 408 and will no longer rotate. The upward-moving landing gear 2 will contact the bottom of the rotating rod 402 and drive the entire cargo frame 3 to move upward, completing the transport movement of the cargo frame 3. This achieves the purpose of quickly connecting the cargo frame 3 and the landing gear 2, further improving work efficiency.

[0046] Please refer to this carefully. Figures 1-4 The inner side of the limiting block 408 is formed with an inclined guide groove that matches the outer wall of the guide rod 407. The limiting block 408 is slidably sleeved with the guide rod 407 through the guide groove. The interior of the second fixed seat 403 is formed with a sliding groove for the axial movement of the limiting block 408. The outer wall of the limiting block 408 is generally L-shaped. The inner wall of the U-shaped block 409 is formed with a hole for the end of the limiting block 408 to be inserted. The outer wall of the pressing block 404 is generally T-shaped. The inner wall of the cargo frame 3 is formed with a sliding groove for the vertical movement of the pressing block 404 and the L-shaped linkage rod 406. The outer walls of the first fixed seat 401, the rotating rod 402, and the second fixed seat 403 are generally N-shaped. The bottom of the rotating rod 402 is provided with a groove that matches the outer wall of the landing gear 2. A rubber pad to increase friction is provided inside the groove.

[0047] In this embodiment: With this structure, after the UAV body 1 moves the cargo frame 3 to the required position, the landing gear 2 falls down and contacts the top of the pressing block 404, giving the pressing block 404 a downward squeezing force. This causes the pressing block 404 to exert a downward pulling force on the L-shaped linkage rod 406 and the guide rod 407. The downward-moving guide rod 407 exerts a downward pulling force on the inner guide groove of the limiting block 408, causing the limiting block 408 to move away from the groove of the U-shaped block 409. At this time, the rotating rod 402 can be rotated so that the rotating rod 402 no longer contacts the top of the second fixed seat 403, exposing the space for the landing gear 2 to move upward, thus achieving the purpose of quickly separating the cargo frame 3 and the landing gear 2.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
