Description

Technical Field

[0001] This utility model relates to the field of heavy-duty drone transportation technology, and more specifically, it relates to a heavy-duty drone transportation device. Background Technology

[0002] Heavy-duty drones are unmanned aerial vehicles specifically designed for transporting goods, typically featuring large payload capacity, long range, and high stability. They can fly automatically or remotely, quickly delivering heavy items, making them particularly suitable for remote areas, emergency rescue operations, or scenarios with poor transportation access.

[0003] Patent document CN222728246U discloses a heavy-duty drone transportation device. This device includes a drone body with an installation mechanism. The installation mechanism includes a sliding mechanism, a connecting rod, an insertion rod, a fixing sleeve, an adjusting sleeve, a positioning rod, a compression spring, a pressure plate, and a release mechanism. The sliding mechanism is connected to both the drone body and the connecting rod. The connecting rod has an insertion rod mounted on it. The fixing sleeve is slidably connected to the insertion rod, and the adjusting sleeve is threaded into the fixing sleeve. The insertion rod has a positioning rod with a rounded head. The insertion of the insertion rod, the pressing action of the pressure plate, and the self-locking mechanism of the slider ensure the stability and safety of the goods during transportation. This design not only simplifies the operation process and improves operational efficiency but also enhances the reliability and adaptability of the transportation device.

[0004] However, during use, because the cargo is fixed between the two lateral frames, and these frames can slide on the connecting rod via guide sleeves, when the drone moves in flight, especially during acceleration, deceleration, or turning maneuvers, the lateral frames will slide along the connecting rod due to inertia. This sliding causes the fixed cargo to shift, thus changing the overall center of gravity distribution of the drone, easily affecting the drone's flight stability, increasing the burden on the control system, and in severe cases, even endangering flight safety. Secondly, while the device uses two lateral frames to clamp and fix the cargo, providing basic fixation, the lack of effective limiting components on the other two sides of the cargo means that during actual transportation, when the drone encounters airflow disturbances, sharp turns, or acceleration / deceleration, the cargo is prone to sliding between the lateral frames, posing a risk of the cargo falling off.

[0030] Please see Figures 1-5 A heavy-duty unmanned aerial vehicle (UAV) transport device includes a UAV body 1, a transport frame 2 fixedly mounted on the lower end of the UAV body 1, a drive chamber 3 inside the transport frame 2, a bidirectional lead screw 4 rotatably mounted inside the drive chamber 3, a throttle 5 fixedly mounted on one end of the bidirectional lead screw 4 passing through the transport frame 2, two drive seats 6 threaded on the bidirectional lead screw 4, the drive seats 6 being slidably connected to the drive chamber 3 via a track structure, two drive plates 7 being slidably connected inside the drive chamber 3 via the track structure, a groove 8 on one side of each drive plate 7, two push seats 9 movably mounted in the groove 8, push rods 10 being hingedly connected between the two push seats 9 and the two drive seats 6 respectively, the two push rods 10 being rotatably connected to each other, and two connecting arms 11 fixedly mounted on the lower end of each drive plate 7, the lower ends of the two connecting arms 11 extending into the transport frame 2 and fixedly mounted with clamping plates 12.

[0031] In this embodiment, when goods need to be transported, the packaged goods are placed in the transport frame 2, and the handle 5 is turned. The handle 5 drives the bidirectional lead screw 4 to rotate. Since the bidirectional lead screw 4 is provided with two threaded areas in opposite directions, the two drive seats 6 move away from each other along the sliding connection with the drive chamber 3. The drive seats 6 drive the push rod 10 to rotate. While the push rod 10 is rotating, it will drive the push seat 9 to move along the slide groove 8. At the same time, the push seat 9 pulls the drive plate 7 through the slide groove 8, so that the two drive plates 7 move in adjacent directions. The drive plate 7 drives the connecting arm 11 to move along the moving groove 14. The connecting arm 11 drives the clamping plate 12 to move, so that the two clamping plates 12 cooperate to clamp and fix the goods.

[0032] Please see Figures 1-5 As an implementation method for limiting and blocking the other two sides of the cargo: Limiting plates 13 are hinged to both sides of the transport frame 2. Four movable slots 14 that cooperate with the connecting arms 11 are provided on the transport frame 2. A connecting block 15 is fixedly provided at the lower end of the limiting plate 13. A fixed frame 16 is fixedly provided at the lower end of the transport frame 2. A screw 17 is rotatably provided inside the fixed frame 16. One end of the screw 17 passes through the fixed frame 16 and is fixedly provided with a handle 18. A fixed plate 19 is threadedly connected to the screw 17. Fixed rods 20 are fixedly provided at both ends of the fixed plate 19 that pass through the fixed frame 16. Each fixed rod 20 is inserted into the connecting block 15. A fixing hole 21 that cooperates with the fixed rod 20 is provided on the connecting block 15. Two landing gears 22 are fixedly provided at the lower end of the UAV body 1. Two support rods 23 are fixedly provided on the two landing gears 22. The two support rods 23 are fixedly connected to the lower end of the transport frame 2.

[0033] More specifically, when placing goods into the transport frame 2, the limiting plate 13 can be pulled to open one side of the transport frame 2. After the goods are placed, the limiting plate 13 is rotated back to its original position. The limiting plate 13 drives the connecting block 15 to move, so that the fixing hole 21 on the connecting block 15 is aligned with the fixing rod 20. Turn the handle 18, and the handle 18 drives the screw 17 to rotate. Since the screw 17 is threadedly connected to the fixing plate 19, the fixing plate 19 moves along the fixing frame 16. The fixing plate 19 drives the two fixing rods 20 to move, so that the fixing rods 20 are inserted into the fixing hole 21, thereby fixing the two connecting blocks 15 and fixing the two limiting plates 13. The limiting plate 13 can block the two sides of the goods to prevent them from moving and falling off. At the same time, the two support rods 23 can strengthen the support of the transport frame 2, increasing the load-bearing capacity and stability of the transport frame 2.

[0034] In summary, when the equipment is in use or running: when goods need to be transported, the packaged goods are placed in the transport frame 2, and the handle 5 is turned. The handle 5 drives the bidirectional lead screw 4 to rotate. Since the bidirectional lead screw 4 has two threaded areas in opposite directions, the two drive seats 6 move away from each other along the sliding connection with the drive chamber 3. The drive seats 6 drive the push rod 10 to rotate. While the push rod 10 is rotating, it will drive the push seat 9 to move along the slide groove 8. At the same time, the push seat 9 pulls the drive plate 7 through the slide groove 8, so that the two drive plates 7 move in adjacent directions. The drive plate 7 drives the connecting arm 11 to move along the moving groove 14. The connecting arm 11 drives the clamping plate 12 to move, so that the two clamping plates 12 cooperate to clamp and fix the goods.

[0035] When placing goods into the transport frame 2, the limiting plate 13 can be pulled to open one side of the transport frame 2. After the goods are placed, the limiting plate 13 is rotated back to its original position. The limiting plate 13 drives the connecting block 15 to move, so that the fixing hole 21 on the connecting block 15 is aligned with the fixing rod 20. Turn the handle 18, and the handle 18 drives the screw 17 to rotate. Since the screw 17 is threadedly connected to the fixing plate 19, the fixing plate 19 moves along the fixing frame 16. The fixing plate 19 drives the two fixing rods 20 to move, so that the fixing rods 20 are inserted into the fixing hole 21, thereby fixing the two connecting blocks 15 and fixing the two limiting plates 13. The limiting plate 13 can block the two sides of the goods to prevent them from moving and falling off. At the same time, the two support rods 23 can strengthen the support of the transport frame 2, increasing the load-bearing capacity and stability of the transport frame 2.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
