[0047] As a preferred embodiment, the hook clamping device 7 includes a lifting motor 71 and a clamping connection block 72. The lifting motor 71 is connected to the top of the clamping connection box 4. The bottom of the lifting motor 71 is connected with a lifting telescopic rod 711, and one end of the lifting telescopic rod 711 passes through the telescopic through hole 44 and is connected to the center position of the top end of the clamping connection block 72.

Before clamping the storage compartment, the hook identification camera 722 identifies and confirms the position and direction of the top hook of the storage compartment.

[0048] As a preferred embodiment, a lock block motor 721 is connected to one side of the clamping connection block 72, and a telescopic lock rod 7211 is connected to one end of the lock block motor 721 close to the clamping connection block 72. A fixed lock hole 723 is provided on the side of the clamping connection block 72 away from the lock block motor 721, and the telescopic lock rod 7211 is fitted with the fixed lock hole 723. Further, when the clamping connection block 72 descends to a position flush with the hook of the storage compartment, the lock block motor 721 drives the telescopic lock rod 7211 to expand and contract. During the expansion and contraction of the telescopic lock rod 7211, the telescopic lock rod 7211 approaches or moves away from the fixed lock hole 723. When the telescopic lock rod 7211 is inserted into the fixed lock hole 723, the buckle fixation of the sling of the storage compartment is completed. When the telescopic lock rod 7211 moves away from the fixed lock hole 723, the sling of the storage compartment is released, thus completing the release and delivery work of the storage compartment.

[0049] The working process of this application is as follows: First, the UAV main body 1 moves by flying through multiple UAV wings 2. The UAV main body 1 monitors and identifies the area and items for dropping and picking up below through the recognition camera 11. The UAV main body 1 lands on the ground through the UAV support base 31 at the bottom of the UAV base 3. When the UAV main body clamps and picks up the storage compartment, when the UAV main body descends above the storage compartment, it is clamped and fixed by two storage compartment clamping claws 61 at the bottom of the clamping connection box 4, and the hook of the storage compartment can be hooked by the hook clamping device 7.

[0050] The lifting motor 71 drives the lifting telescopic rod 711 to expand and contract in the telescopic through hole 44, and the lifting telescopic rod 711 drives the clamping connection block 72 to lift and lower to align with the hook position of the storage compartment. Before clamping the storage compartment, the hook recognition camera 722 identifies and confirms the position and direction of the top hook of the storage compartment. When the clamping connection block 72 descends to a position flush with the hook of the storage compartment, the lock block motor 721 drives the telescopic lock rod 7211 to expand and contract towards the storage compartment. During the expansion and contraction of the telescopic lock rod 7211, the telescopic lock rod 7211 approaches the fixed lock hole 723. When the telescopic lock rod 7211 is inserted into the fixed lock hole 723, the buckle fixation of the sling of the storage compartment is completed.

[0051] The clamping motor 6 drives the clamping lead screw 621 to rotate through the steering output block 622. The clamping motor 6 drives the first bevel gear 622 to rotate, and the first bevel gear 622 drives the second bevel gear 623 to rotate. During the rotation of the second bevel gear 623, it drives the clamping lead screw 621 to rotate, thus completing the transmission action in the vertical direction. During the rotation of the clamping lead screw 621, the two driving lead screws 6211 with opposite threads rotate synchronously. During the rotation of the two driving lead screws 6211, they drive the transmission connection blocks 612 connected to them to move towards each other. During the movement of the transmission connection blocks 612, they drive the sliding connection rotating rods 63 connected to them and the four storage compartment clamping claws 61 connected to the sliding connection rotating rods 63 to perform clamping or loosening actions. When the two storage compartment clamping claws 61 approach each other, they complete the clamping and fixing of the storage compartment, and when the two storage compartment clamping claws 61 move away from each other, they complete the loosening and dropping of the storage compartment. During clamping, the fixed shovel plate 611 at the bottom of the storage compartment clamping claw 61 shovels up the bottom of the storage compartment, and during the clamping process, the fixed shovel plate 611 supports and fixes the bottom of the storage compartment;

[0052] During the loosening process, the sliding connection rotating rod 63 moves towards the direction close to the socket rotating cylinder 65. During the movement towards the socket rotating cylinder 65, the connecting runner 634 slides along the direction of the communication groove 652 through the sliding bumps 635 on both sides of it. When the connecting runner 634 moves into the steering annular groove 651 far from the sliding connection rotating rod 63, the sliding connection rotating rod 63 is limited and fixed by the steering annular groove 651. At this time, the rotating sleeve 632 translates on the sliding connection rotating rod 63 in the direction away from the sliding connection rotating rod 63. During the movement of the rotating sleeve 632, it moves in the rotating thread groove 631 of the sliding connection rotating rod 63 through the rotating guiding convex block 633, and the rotating guiding convex block 633 drives the sliding connection rotating rod 63 to rotate through the rotating thread groove 631. When the sliding connection rotating rod 63 rotates, it drives the transmission steering gear 641 to rotate. During the rotation of the transmission steering gear 641, it drives the steering connection gear 642 to rotate in the rotating connection block 64. During the rotation of the steering connection gear 642, it drives the storage compartment clamping claw 61 and the fixed shovel plate 611 connected to its bottom to rotate, so that the storage compartment clamping claw 61 can perform clamping or loosening actions on the storage compartment with a smaller displacement distance, thereby reducing the size of the clamping connection box 4, reducing the load of the drone. When the sliding connection rotating rod 63 moves away from the socket rotating cylinder 65, and when the connecting runner 634 reaches the steering annular groove 651 on the side close to the sliding connection rotating rod 63, it performs a reset action to complete the position reset of the storage compartment clamping claw 61.

[0053] When the storage compartment is being dropped, the clamping connection box 4 determines the dropping distance through the distance sensor 43, enabling the storage compartment to complete a safer and smoother dropping operation. The wire winding and unwinding motor 5 drives the wire winding drum 5 to wind and unwind the suspension wire 53. During the winding and unwinding process of the suspension wire 53, the suspension wire 53 is guided towards the direction of the suspension wire connection block 411 through the wire guide wheel 52, and drives the clamping connection box 4 and each connected clamping component to rise and fall through the suspension wire connection 411, thereby lifting or dropping the clamped storage compartment. When reaching the designated dropping position, the clamping motor 6 drives the two groups of storage compartment clamping claws 61 to release the storage compartment, and the clamping motor 6 can drive the telescopic locking rod 7211 to move away from the fixed locking hole 723. When the telescopic locking rod 7211 moves away from the fixed locking hole 723, the relaxation of the storage compartment sling is completed, thus completing the relaxation and dropping operation of the storage compartment. The above is the working principle of the intelligent logistics unmanned aerial vehicle with a quick-change storage compartment structure.
