The movable end of the control telescopic rod 511 contracts, and the movable end of the control telescopic rod 511 drives the rack 513 to move in the direction close to the control telescopic rod 511. The rack 513 drives the gear 512 to rotate in the opposite direction, and the gear 512 drives the rotating plate 222 to rotate, so that the windshield 2232 is always in the windward position.

[0046] When one of the two groups of third adjustment plates 525 is in the windward position, the wind drives one of the third adjustment plates 525 to rotate, and the third adjustment plate 525 squeezes the movable end of the third adjustment telescopic rod 526. The volume of the rod cavity of the third adjustment telescopic rod 526 increases, and the liquid in the two rodless cavities of the storage telescopic rods 43 flows through the pipeline to the rod cavity of the third adjustment telescopic rod 526. The volume of the rodless cavity of the storage telescopic rod 43 decreases, and the movable end of the storage telescopic rod 43 contracts, so that the support rod 42 is in a vertical state.

[0047] The implementation principle of the drone logistics intelligent transportation device in this embodiment of the application is as follows: During operation, the operator controls the controller 26 to extend the movable end of the telescopic rod 25, expanding the size of the storage cavity formed by the sliding box 22 and the transport box 2 to accommodate cargo of varying sizes. To load cargo, the operator slides the stopper rod 311 away from the door 21, disengaging it from the door 21. The operator then rotates the door 21 to open the transport box 2. During the rotation of the door 21, the door 21 disengages from the movable end of the push-on telescopic rod 321, causing the second spring 322 to return to its original position. The movable end of the push-on telescopic rod 321 extends, causing the liquid in the rodless cavity of the stopper telescopic rod 323 to flow through the pipe into the rodless cavity of the push-on telescopic rod 321. The movable end of the stopper telescopic rod 323 retracts, disengaging it from the sliding box 22, and causing the sliding door 24 to slide down under its own weight. The operator places fragile cargo into the sliding box 22 and hangs non-fragile cargo from the bottom of the drone using the hook 2231.

[0048] When the drone is flying, the windshield 2232 guides the airflow at the bottom of the drone to both sides, so that the airflow is not easy to directly impact the cargo hung by the hook 2231. When the flight direction of the drone changes, If the first adjustment plate 521 is in a windward position, the wind drives the first adjustment plate 521 to rotate, and the first adjustment plate 521 drives the movable end of the first adjustment telescopic rod 522 to retract. The liquid in the rodless cavity of the first adjustment telescopic rod 522 flows through the pipeline into the rodless cavity of the control telescopic rod 511, and the movable end of the control telescopic rod 511 extends. The movable end of the control telescopic rod 511 drives the rotating plate 222 to rotate through the rack 513 and the gear 512.

[0049] If the second adjustment plate 523 is in the windward position, the wind drives the second adjustment plate 523 to rotate, and the second adjustment plate 523 drives the movable end of the second adjustment telescopic rod 524 to retract, controlling the liquid in the rodless cavity of the telescopic rod 511 to flow into the rod cavity of the second adjustment telescopic rod 524 through the pipeline, controlling the movable end of the telescopic rod 511 to retract, and controlling the movable end of the telescopic rod 511 to drive the rotating plate 222 to rotate through the gear 512 and the rack 513, so that the windshield 2232 is always in the windward position.

[0050] If one of the two groups of third adjustment plates 525 is in a windward position, the wind drives one of the third adjustment plates 525 to rotate, and the third adjustment plate 525 drives the movable end of the third adjustment telescopic rod 526 to retract. The liquid in the rodless cavities of the two storage telescopic rods 43 flows through the pipeline into the rod cavity of the third adjustment telescopic rod 526, and the movable end of the storage telescopic rod 43 retracts, so that the support rod 42 is in a vertical state, reducing the wind resistance during the flight of the drone.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
