Description

Technical Field

[0001] The present application relates to the field of drone intelligent logistics, and more specifically, to an intelligent logistics drone with a quick-change storage compartment structure. Background Art

[0002] Drone express delivery is the use of radio remote control equipment and self-contained program control devices to carry packages in unmanned low-altitude aircraft and automatically deliver them to the destination. Its advantages mainly lie in solving the distribution problem in remote areas, improving distribution efficiency, and reducing labor costs.

[0003] After searching, the existing patent (application number CN202110074277.9) discloses a logistics drone and a loading and unloading conveying platform, including a storage bin, a receiving platform and a connecting rod and other components. Through the tilting downward action of the drone, the push rod is pressed against the push block 1, first completing the separation of the positioning block and the positioning groove (i.e. unlocking), and then the delivery door and the inlet door are rotated in the opposite direction by 90 degrees, so that the delivery door can move the goods out to the transmission belt, and at the same time, another cargo can be moved to the inlet door along the climbing belt. The drone moves vertically upward, and the push block 2 is reset and rotated 90 degrees by the push rod, thereby completing the reset of the delivery door and the inlet door, and the positioning block is inserted into the positioning groove (i.e. locked), realizing the simultaneous completion of unloading and loading, which can speed up the delivery efficiency of the drone; further, the goods are moved out through the transmission belt, and the goods are moved in through the climbing belt, avoiding low manual efficiency and avoiding the electric drive mechanism in the prior art from opening the door, thereby increasing the endurance of the drone. In the process of realizing this application, the inventor found that the prior art has the following problems:

[0004] Existing logistics drones require manual assistance to connect the storage compartment or replace the storage compartment through the loading and unloading platform. In the case of delivery and transportation by drone, the drone needs to independently complete the placement of the storage compartment. When delivering the storage compartment, the storage compartment needs to be quickly and safely delivered to the designated location, and the goods need to be quickly and accurately clamped and fixed when picking up. Most of the existing logistics drones only fix the storage compartment by clamping. During the transportation process, the storage compartment may slip off from the direction of the vertical clamping device due to the swing of the drone;

[0049] The working process of the present application is as follows: first, the drone body 1 flies and moves through multiple sets of drone wings 2, and the drone body 1 monitors and identifies the area and items for dropping and picking up goods below through the identification camera 11, and the drone body 1 is placed on the ground through the drone support seat 31 at the bottom of the drone base 3, and when the drone body 1 clamps the storage compartment to pick up goods, when the drone body falls above the storage compartment, it is clamped and fixed by the two sets of 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;

The two groups of storage compartment clamping claws 61 complete the clamping and fixing of the storage compartment when they are close to each other, and complete the release and release of the storage compartment when the two groups of storage compartment clamping claws 61 move away from each other.

[0052] During the relaxation process, the sliding connection rotating rod 63 moves toward the direction approaching the sleeve rotating cylinder 65. During the process of approaching the sleeve rotating cylinder 65, the connecting rotating wheel 634 slides along the direction of the connecting groove 652 through the sliding protrusions 635 on both sides thereof. When the connecting rotating wheel 634 moves into the steering annular groove 651 away 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, the rotating sleeve 632 moves in the rotating thread groove 631 of the sliding connection rotating rod 63 through the rotating guide protrusion 633, and the sliding connection rotating rod 63 is driven to rotate through the rotating thread groove 631. When the sliding connection rotating rod 63 is loosened, the sliding connection rotating rod 63 moves in the rotating thread groove 631 of the sliding connection rotating rod 63 through the rotating guide protrusion 633. During the rotation of the connecting rod 63, the transmission steering gear 641 is driven to rotate, and during the rotation of the transmission steering gear 641, the steering connecting gear 642 is driven to rotate in the rotating connecting block 64, and during the rotation of the steering connecting gear 642, the storage compartment clamping claw 61 and the fixed shovel plate 611 connected to its bottom are driven to rotate, so that the storage compartment clamping claw 61 can clamp or release the storage compartment with a smaller displacement distance, thereby reducing the size of the clamping connection box 4, thereby reducing the weight of the drone, and when the sliding connecting rod 63 moves in the direction away from the sleeve rotating cylinder 65, and the connecting wheel 634 performs a reset action when it reaches the steering annular groove 651 close to the side of the sliding connecting rod 63, the position reset of the storage compartment clamping claw 61 is completed.

[0053] When the storage compartment is released, the clamping connection box 4 determines the release distance through the distance sensor 43, so that the storage compartment can complete a safer and smoother release work, and the retracting and discharging motor 5 drives the suspension wire reel 5 to retract and release the suspension wire 53, and the suspension wire 53 is guided to the direction of the suspension wire connection block 411 through the wire pulley 52 during the release and retraction process, and the clamping connection box 4 and the various clamping components connected thereto are driven to rise and fall through the suspension wire connection 411, so as to lift or release the clamped storage compartment, and when it reaches the designated release 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 in the direction away from the fixed locking hole 723, and when the telescopic locking rod 7211 is away from the fixed locking hole 723, the storage compartment lifting ring is released, thereby completing the release and release work of the storage compartment. The above is the working principle of the intelligent logistics drone with a quick-change storage compartment structure.
