[0016] 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.

[0017] Please see Figure 1-6 One embodiment provided by this utility model: An expandable cargo hold drone includes a drone body 1, a cargo box 2 fixedly connected to the bottom of the drone body 1, two sets of limiting grooves 21 and two sets of storage slots 22 on the bottom of the cargo box 2, slots 23 at the front and rear ends of the bottom of the cargo box 2, a base plate 3 slidably connected to the bottom of the cargo box 2, two sets of connecting rods 31 fixedly connected to the top of the base plate 3, limiting blocks 32 fixedly connected to the top of the connecting rods 31, two sets of mounting blocks 33 symmetrically fixedly connected to the front and rear ends of the top of the base plate 3, slots 34 on the surface of the mounting blocks 33, two sets of fixing cylinders 35 fixedly connected to the top of the base plate 3, two sets of winding grooves 51 fixedly connected to the top of the base plate 3, and engaging structures 4 inside the front and rear ends of the cargo box 2. 4 includes a slide groove 41, inside which a slider 42 is slidably connected. Inside the slider 42, two sets of fixing rods 43 are fixedly connected. One end of the fixing rod 43 is fixedly connected to a locking block 44, and the other end of the fixing rod 43 is fixedly connected to a pull rod 46. A spring 45 is sleeved on the outside of the fixing rod 43. The inside of the fixing cylinder 35 is provided with a winding structure 5, which includes a winding groove 51. Inside the winding groove 51, a rotating rod 52 is rotatably connected. The top and bottom of the rotating rod 52 are fixedly connected to limit blocks 53. Two sets of coil springs 54 are symmetrically fixedly connected to the surface of the rotating rod 52. A rope net 55 is wound on the surface of the rotating rod 52. One end of the rope net 55 is fixedly connected to a hook 56. The surface of the fixing cylinder 35 is fixedly connected to a hanging ear 57. The top and bottom of the trough 51 are provided with sliding grooves 58, and the top and bottom of the two sets of sliding grooves 58 are respectively provided with limiting grooves 59. A base plate 3 and a retracting structure 5 are provided. When it is necessary to expand the cargo box 2, the base plate 3 is lowered and the limiting block 32 moves to the bottom of the limiting groove 21. By pulling the hook 56 at the end of the rope net 55 and hanging it on the hanging ear 57, the rope net 55 can be quickly unfolded to form lateral protection, preventing the goods from falling from the top of the base plate 3, significantly increasing the cargo space. The operation is extremely simple. The rope net 55 is lightweight and occupies very little space when stored in the fixed cylinder 35. The coil spring 54 mechanism allows the rope net 55 to automatically and smoothly retract into the fixed cylinder 35 after unloading the hanging ear 57. The process is smooth and easy to reuse, while avoiding the tangling caused by the loose rope net 55. To mitigate risks, the storage space of cargo box 2 can be expanded, improving the drone's cargo adaptability and transportation flexibility. An installation block 33 and a locking structure 4 are incorporated. Initial guiding and positioning are achieved through the sliding of limit block 32 within limit groove 21. The locking structure 4, through the automated engagement of locking block 44 and locking groove 34, the automatic sliding of the inclined surface of installation block 33 into the inclined surface of locking block 44, and the linkage with spring 45, enables quick and reliable locking and unlocking of the base plate 3 and the bottom of cargo box 2. Pulling the lever 46 significantly improves the convenience of assembly and disassembly and the strength of the connection. Limit groove 21, connecting rod 31, storage groove 22, and fixing cylinder 35 are respectively positioned diagonally at the bottom of cargo box 2. This diagonal layout effectively distributes the load on the base plate 3.After the rope net is deployed to 55mm, it provides good support and balance for the entire bottom structure, improving the structural rigidity of the system and the flight stability of the UAV in the expanded state.

[0018] Furthermore, two sets of limiting grooves 21 are respectively set at one diagonal position at the bottom of the cargo box 2, and two sets of connecting rods 31 are respectively set at the corresponding diagonal position at the top of the base plate 3. Two sets of limiting blocks 32 are respectively slidably connected in the two sets of limiting grooves 21. The radius of the limiting block 32 is larger than the radius of the connecting rod 31. The limiting block 32 and the limiting groove 21 cooperate to limit the movement of the base plate 3 at the bottom of the cargo box 2, making the movement of the base plate 3 more stable.

[0019] Furthermore, two sets of storage slots 22 are respectively set at the other diagonal position at the bottom of the cargo box 2, and two sets of fixing cylinders 35 are respectively slidably connected in the two sets of storage slots 22. The limiting slot 21, connecting rod 31, storage slot 22, and fixing cylinder 35 are respectively set at the diagonal position at the bottom of the cargo box 2. This diagonal layout effectively disperses the load on the bottom plate 3 and provides good support and balance for the entire bottom structure after the rope net 55 is unfolded, improving the structural rigidity of the system and the flight stability of the UAV in the expanded state.

[0020] Furthermore, the two ends of the fixing rod 43 pass through the inner wall of one side of the slider 42 and the slide groove 41 respectively and are fixedly connected to the locking block 44 and the pull rod 46. The two ends of the spring 45 are fixedly connected to the inner wall of the slide groove 41 and the surface of the slider 42 respectively. The slot 23 is connected to the slide groove 41. The locking block 44 is slidably connected in the slot 23 and the slide groove 41. Pulling the pull rod 46 can drive the slider 42 to slide inside the slide groove 41 through the fixing rod 43, thereby adjusting the position of the locking block 44 in the slot 23 and the slide groove 41.

[0021] Furthermore, the mounting block 33 is slidably connected in the slot 23, the top of the mounting block 33 is provided with an angle, the cross section of the locking block 44 is triangular, the angle of the locking block 44 is set downward, the locking block 44 is slidably connected in the slot 34, the angle of the mounting block 33 and the angle of the locking block 44 cooperate, and when the mounting block 33 moves into the slot 23, it can push the locking block 44 to move in the slot 23 and the slide groove 41.

[0022] Furthermore, the second limiting block 53 is rotatably connected within the second limiting groove 59. The radius of the second limiting block 53 is larger than the radius of the rotating rod 52. The winding groove 51, the second sliding groove 58, and the second limiting groove 59 are interconnected. The two ends of the coil spring 54 are fixedly connected to the surface of the rotating rod 52 and the inner wall of the second sliding groove 58, respectively. The second limiting block 53 cooperates with the second limiting groove 59 to ensure that the rotating rod 52 can only rotate inside the fixed cylinder 35. When the rotating rod 52 rotates, the coil spring 54 will deform, causing the rotating rod 52 to tend to return to its original shape.

[0023] Furthermore, one end of the rope net 55 is fixedly connected to the surface of the rotating rod 52, and the other end of the rope net 55 is fixedly connected to the hook 56. The hook 56 is J-shaped and cooperates with the hanging ear 57. By pulling the hook 56 at the end of the rope net 55 and hanging it on the hanging ear 57, the rope net 55 can be quickly unfolded to form lateral protection and prevent the goods from falling from the top of the bottom plate 3.

[0024] Working principle: First, pull the pull rods 46 at both ends of the cargo box 2 outward to overcome the elastic force of the spring 45, so that the locking block 44 exits the slot 34 of the mounting block 33 on the bottom plate 3, and the bottom plate 3 is unlocked. At this time, the bottom plate 3 can be slid down, and the hooks 56 at the ends of the rope net 55 can be pulled out from the two sets of fixed cylinders 35 respectively. The hooks 56 are hooked on the hanging ears 57 on the outside of the fixed cylinder 35. The rope net 55 is pulled out and unfolded, forming a protective space on the top side of the bottom plate 3. At this time, the lowered bottom plate 3, the unfolded rope net 55 and the cargo box 2 can be used to form a larger cargo area. After unloading the goods, the hooks 56 are removed from the hanging ears 57. Under the restoring force of the coil spring 54, the rope net 55 automatically rolls back and wraps around the rotating rod 52 and is stored inside the fixed cylinder 35. The second limiting block 53 rotates in the second limiting groove 59 to ensure stability. Push the base plate 3 upwards. When the mounting block 33 contacts the inclined surface of the locking block 44, the locking block 44 will automatically slide into the locking groove 34 of the mounting block 33 under the action of the spring 45, thus completing the quick and automatic locking of the base plate 3 and restoring it to its initial state.

[0025] 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.
