[0002] With the rapid development of drone technology, its application in logistics, emergency rescue, and agricultural and forestry plant protection is becoming increasingly widespread. When performing missions, drones typically need to carry different cargo holds or mission modules to achieve functions such as cargo delivery and equipment mounting. Therefore, the connection and fixing method between the drone and the cargo hold directly affects the efficiency, safety, and convenience of the overall operation.

[0003] Currently, traditional methods of connecting drones to cargo warehouses mostly involve bolt fastening, buckle locking, or strap fixing. These methods are generally cumbersome to operate, often requiring tools to connect or disconnect the cargo warehouse, which consumes a lot of time and seriously affects the rapid response capability of the mission.

[0004] Therefore, in order to improve the convenience and reliability of the connection and locking between the drone and the cargo warehouse, we propose a drone-borne cargo warehouse locking device. Utility Model Content

The locking beads are movably inserted into the bead holes. A sleeve is also sleeved on the outer side of the connecting tube, and the sleeve stops on the outer side of the plurality of locking beads.

[0012] The outer side of the docking post has an inner retractable annular groove that engages with the locking bead.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 As one embodiment of the present utility model, a drone cargo hold locking device is disclosed. The device is installed between the drone 1 and the cargo hold 2. Specifically, the locking device includes a locking mechanism 3 and an alignment mechanism 4.

[0027] The locking mechanism 3 includes a docking column 31 fixedly installed on the platform of the UAV 1, and a docking pipe 32 fixedly installed at the bottom of the cargo compartment 2;

[0028] The docking post 31 and the docking tube 32 are inserted into each other, and a limiting part 33 that stops the upper end of the docking tube 32 is also provided on the outside of the docking post 31.

[0029] A locking assembly 34 for locking the docking post 31 is also provided on the outside of the docking tube 32.

[0030] It should be noted that, in this embodiment, there are two locking mechanisms 3 to improve the connection stability between the cargo hold 2 and the drone 1.

[0031] In some embodiments, the locking assembly 34 of the present invention includes a plurality of locking beads 341, and a plurality of bead holes 321 are provided on the outer side of the connecting tube 32. The locking beads 341 are movably inserted into the bead holes 321. Of course, the inner diameter of the bead hole 321 should be smaller than the outer diameter of the locking beads 341, so as to prevent the locking beads 341 from falling out of the bead hole 321. A sleeve 342 is also sleeved on the outer side of the connecting tube 32, and the sleeve 342 stops on the outer side of the plurality of locking beads 341.

[0032] The outer side of the docking post 31 has an inner retractable annular groove 311 that engages with the locking bead 341.

[0033] Specifically, in this embodiment, a locking bead 341 is used to engage the inner retractable groove 311 on the outside of the docking post 31, thereby achieving the connection locking between the docking tube 32 and the docking post 31.

[0034] During connection, when the docking post 31 is inserted into the inside of the docking tube 32, the limiting part 33 stops the insertion position of the docking post 31. At this time, the sleeve 342 can be pushed upward. When the sleeve 342 moves upward, its inner side will abut against several locking beads 341 and move inward until it is locked into the inside of the inner shrinking ring groove 311. In this way, the connection and locking between the docking post 31 and the docking tube 32 can be completed.

[0035] Based on the above embodiments, in this embodiment, the outer end of the sleeve 342 is provided with an inner narrowing opening 343, and the locking bead 341 has an outward displacement space at the inner narrowing opening 343;

[0036] An installation groove 344 is also formed on the inner side of the sleeve 342, and a spring 345 is placed between the installation groove 344 and the outer wall of the connecting tube 32.

[0037] The design of the inward-recessed opening 343 is to provide a radially outward space for the locking beads 341. That is, when it is necessary to disassemble the cargo compartment 2 and the drone 1, the aforementioned sleeve 342 can be slid downward. When the inward-recessed opening 343 of the sleeve 342 is opposite to several locking beads 341, since the locking beads 341 have a radially outward space, the cargo compartment 2 can be lifted upward, and the docking column 31 can be separated from the inside of the docking tube 32. The operation is simple and convenient.

[0038] Furthermore, in this embodiment, a locking groove 346 is provided on the outer side of the sleeve 342, and a locking pin 347 is fixedly installed on the outer side of the connecting pipe 32, and the locking pin 347 is slidably connected in the locking groove 346.

[0039] Specifically, in this embodiment, the locking groove 346 has a U-shaped structure, and the locking pin 347 and the connecting tube 32 are threaded together.

[0040] That is, during the locking and unlocking process, the position of the sleeve 342 can be controlled by rotating the position of the sleeve 342 to lock the bent part of the locking pin 347 and the locking groove 346.

[0041] For example, during the initial connection process, the sleeve 342 can be slid down. At this time, the locking pin 347 slides to the upper side of the locking groove 346. Rotate the sleeve 342 so that the bent part on its upper side engages with the locking pin 347. At this time, the position of the sleeve 342 can be fixed. Since the locking ball 341 has radially movable space at this time, the docking post 31 can be freely inserted into the docking tube 32 when connecting the cargo compartment 2.

[0042] Conversely, after the connection is completed, the locking pin 347 and the lower side of the locking groove 346 engage, which can fix the locking position of the sleeve 342 to avoid shaking during transportation.

[0043] In some embodiments, the alignment mechanism 4 of the present invention includes an alignment tube 41 fixedly installed on the platform of the UAV 1 and an alignment column 42 fixedly installed at the bottom of the cargo compartment 2, wherein the alignment column 42 and the alignment tube 41 are connected together.

[0044] Specifically, in this embodiment, there are four alignment tubes 41 and four alignment posts 42 in a matrix distribution to improve the stability of the docking connection.

[0045] In summary, this utility model achieves rapid connection and locking between the cargo compartment 2 and the drone 1 through the design of the locking mechanism 3 and the alignment mechanism 4. The locking mechanism 3 consists of the docking column 31 on the drone 1 platform and the docking pipe 32 at the bottom of the cargo compartment 2. During operation, the cargo compartment 2 can be automatically aligned and locked by simply loading it onto the drone 1 from above. This design greatly simplifies the loading process and significantly improves the loading and unloading efficiency of the cargo compartment 2 as well as the convenience and reliability of locking it with the drone 1.

[0046] 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.
