Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) logistics technology, specifically a logistics transportation UAV. Background Technology

[0002] With the explosive growth of e-commerce and on-demand delivery, traditional last-mile logistics relies on manual labor or vehicles for cargo handling, often hampered by terrain obstacles and traffic congestion, resulting in low efficiency and high costs. Logistics drones have emerged to address this challenge. Leveraging their vertical takeoff and landing capabilities and aerial maneuverability, they can overcome obstacles to deliver goods directly, making them particularly suitable for remote areas such as mountainous regions and islands, as well as peak-hour urban times. Integrating high-precision positioning, intelligent obstacle avoidance, and load balancing technologies, they can reliably and accurately handle small and medium-sized goods, significantly shortening delivery times. Currently deployed in emergency delivery and rural logistics, they have become a key tool for solving last-mile handling challenges and driving the upgrade of smart logistics towards higher efficiency.

[0003] Currently, most logistics transport drones are equipped with fixed racks at the bottom of the fuselage for placing goods. However, during flight, due to airflow disturbances, attitude adjustments, or take-off and landing impacts, the goods are prone to displacement and shaking. This can not only cause collision damage but also interfere with the drone's center of gravity balance, affecting flight stability and control precision, and reducing transportation reliability. Therefore, this invention provides a logistics transport drone. Summary of the Invention

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figures 1 to 5 As shown in the figure, a logistics transportation drone according to an embodiment of the present invention includes a drone body 1, a set of wings 2 on the drone body 1, and a pair of landing gears 3 fixedly connected to the bottom surface of the drone body 1; a placement block 4 is fixedly connected to the bottom surface of the drone body 1, and an opening is provided on one side of the placement block 4; a pair of symmetrically arranged round rods 5 are fixedly connected to the outer wall of the placement block 4, and the side of the round rods 5 near the placement block 4 is open; a sliding rod 6 is provided inside the round rod 5, and the sliding rod 6 passes through the side wall of the placement block 4 to reach its interior; a fixing plate 7 is fixedly connected to the end of the sliding rod 6 away from the round rod 5; and a moving component for driving the sliding rod 6 to move is provided on the placement block 4.

[0029] This application allows the goods to be transported to be placed in the placement block 4, and then the sliding rod 6 is controlled to move towards the side closer to the placement block 4 by means of the moving component. At this time, the sliding rod 6 will push the fixing plate 7, so that the fixing plate 7 clamps the goods, thereby improving the stability of the goods in the placement block 4 when the drone body 1 is in flight, and thus improving the stability of the drone body 1 in flight.

[0030] The moving component includes a groove 9 formed on the bottom surface of the inner wall of the placement block 4, a slider 11 slidably connected in the groove 9, a lead screw 10 threadedly connected in the slider 11, the lead screw 10 being rotatably connected to the inner wall of the groove 9, a motor for driving the lead screw 10 to rotate being provided on the outer wall of the placement block 4, and a push plate 14 fixedly connected to the top surface of the slider 11.

[0031] After the goods are transported to the designated location, the drone body 1 will land. At this time, the motor can start the lead screw 10 to rotate, so that the lead screw 10 drives the slider 11 to move away from the motor. The slider 11 will drive the push plate 14 to move, so that the push plate 14 pushes the goods in the placement block 4, thereby pushing the goods out of the placement block 4 without manual operation to remove the goods. Afterwards, the drone body 1 can quickly return to home. By controlling the lead screw 10 to reverse through the motor, the slider 11 can drive the push plate 14 to reset.

[0032] The moving assembly also includes a rectangular block 15 slidably connected to the side wall of the placement block 4. A connecting block 12 is slidably and sealed to the surface of the rectangular block 15. The side of the connecting block 12 closest to the slider 11 is fixedly connected to the placement block 4. The slide rod 6 is slidably and sealed to the inner wall of the round rod 5. A connecting pipe 27 communicates between the inside of the round rod 5 and the inside of the placement block 4. A first spring 8 is fixedly connected between the side of the slide rod 6 away from the fixed plate 7 and the inner wall of the round rod 5. A second spring 13 is fixedly connected between the rectangular block 15 and the inner wall of the placement block 4.

[0033] After loading the goods into the placement block 4, the motor drives the lead screw 10 to reverse. At this time, the slider 11 will slide towards the side closer to the motor, causing the push plate 14 to push the rectangular block 15. This allows the rectangular block 15 to push the gas in the connecting block 12 from the connecting pipe 27 into the round rod 5. The gas will then push the slide rod 6, causing the slide rod 6 to push the fixing plate 7, which in turn clamps the goods.

[0034] The bottom surface of the inner wall of the placement block 4 is provided with a pair of storage slots 16. A connecting plate 17 is provided in the storage slot 16. A set of rotating shafts 18 are rotatably connected to the top surface of the connecting plate 17. When the goods in this application enter the placement block 4, they will come into contact with the rotating shafts 18. At this time, the rotating shafts 18 can be used to assist the loading of the goods, so as to reduce friction and improve the convenience of the workers when loading.

[0035] The connecting plate 17 is slidably connected to the inner wall of the storage groove 16. A set of driving springs 20 is fixedly connected between the bottom surface of the connecting plate 17 and the inner wall of the storage groove 16. A magnetic block 19 is fixedly connected to the bottom surface of the connecting plate 17. A connecting groove communicating with the sliding groove 9 is opened in the placement block 4. A magnetic plate 21 that repels the magnetic block 19 is slidably connected in the connecting groove. One side of the magnetic plate 21 is fixedly connected to the slider 11.

[0036] When the drone body 1 is flying, the cargo comes into contact with the rotating shaft 18, and the friction will decrease, which will affect the stability of the cargo. Therefore, when loading the cargo in this application, the repulsion between the magnetic plate 21 and the magnetic block 19 can be used to push the connecting plate 17 so that the height of the rotating shaft 18 is higher than the bottom surface of the inner wall of the placement block 4, so that the cargo comes into contact with the rotating shaft 18. After loading is completed, the slider 11 will move towards the side closer to the motor. At this time, the slider 11 will drive the magnetic plate 21 to move. The length of the connecting groove is longer than the storage groove 16, so that the slider 11 will drive the magnetic block 19 away from the magnetic block 19. At this time, the drive spring 20 will pull the connecting plate 17 downward, so that the rotating shaft 18 no longer comes into contact with the cargo, thereby improving the stability of the cargo during transportation.

[0037] An elastic plate 24 is provided on the side of the fixing plate 7 away from the slide bar 6. The elastic plate 24 has a hollow structure inside. When the fixing plate 7 clamps the goods, the elastic plate 24 will come into contact with the goods. The elasticity of the elastic plate 24 can protect the goods and prevent the fixing plate 7 from damaging the goods.

[0038] The fixed plate 7 has a movable groove 22 on the side away from the slide rod 6. A movable plate 23 is slidably connected to the inner wall of the movable groove 22. The elastic plate 24 is fixedly connected to the side of the movable plate 23 away from the slide rod 6. A set of through holes 25 are opened in the movable plate 23. A set of connecting holes communicating with the through holes 25 are opened on the side of the elastic plate 24 near the movable plate 23. A set of third springs 26 are fixedly connected between the side of the movable plate 23 away from the elastic plate 24 and the inner wall of the movable groove 22. When the fixed plate 7 clamps the goods, the movable plate 23 is pushed by the goods. At this time, the movable plate 23 pushes the gas in the movable groove 22, so that the gas enters the elastic plate 24 after passing through the through holes 25 and the connecting holes. At this time, the elastic plate 24 will expand, so that the elastic plate 24 will further fit with the goods to improve the protection effect of the goods.

[0039] Example 2: Figures 6 to 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a circular shaft 38 is rotatably connected to the inner wall of the placement block 4 near the port, and a baffle 28 is fixedly connected to the surface of the circular shaft 38. A limiting component is provided on the placement block 4 to limit the baffle 28. After the goods are loaded, the limiting component can be used to limit the baffle 28 so that the baffle 28 blocks the port of the placement block 4 to prevent the goods from falling out of the placement block 4. When unloading is required, the limiting component on the baffle 28 is released. Then, when the goods are pushed by the push plate 14 for unloading, the goods will push the baffle 28 to rotate, so that the goods can be pushed out of the placement block 4 normally.

[0040] The limiting component includes a mounting plate 34 fixed to the outer wall of the placement block 4. A mounting block 31 is fixedly connected to the bottom surface of the mounting plate 34. The bottom end of the mounting block 31 is open. A locking plate 32 is provided inside the mounting block 31. A fixing block 29 is fixedly connected to the side of the baffle 28 near the mounting block 31. The top of the fixing block 29 has a locking groove 30 that engages with the locking plate 32. After the goods are loaded, the baffle 28 blocks the port of the placement block 4. Then, the locking plate 32 engages with the locking groove 30 to limit the baffle 28 so that the baffle 28 can block the goods. When unloading is required, the locking plate 32 is moved upward to disengage from the locking groove 30.

[0041] A fourth spring 33 is fixedly connected between the top surface of the clamping plate 32 and the inner wall of the mounting block 31. A conduit 35 connects the interior of the mounting block 31 and the interior of the connecting block 12. A first control valve 36 is fixedly connected to the conduit 35, and a second control valve 37 is fixedly connected to the connecting pipe 27. The clamping plate 32 and the inner wall of the mounting block 31 are in a sealed sliding connection. When the clamping block needs to engage with the slot 30, the first control valve 36 is opened, the second control valve 37 is closed, and then the rectangular block 15 is pushed by the push plate 14, allowing the gas in the connecting block 12 to... The gas enters the mounting block 31 through the conduit 35. At this time, the gas pushes the clamping plate 32 to engage with the clamping groove 30. Then, the first control valve 36 seals the mounting block 31, allowing the clamping block group to engage with the clamping groove 30. When it is necessary to release the limit on the baffle 28, the first control valve 36 is opened, and then the push plate 14 is moved away from the rectangular block 15. At this time, the second spring 13 pushes the rectangular block 15 to move away from the motor. At the same time, the fourth spring 33 pulls the clamping plate 32 to disengage from the clamping groove 30, thereby releasing the limit on the baffle 28.

[0042] Working principle: By placing the goods to be transported into the placement block 4, and then using the moving component to control the slide bar 6 to move towards the side closer to the placement block 4, the slide bar 6 will push the fixing plate 7, so that the fixing plate 7 clamps the goods, thereby improving the stability of the goods in the placement block 4 when the drone body 1 is in flight, and thus improving the stability of the drone body 1 during flight; After the goods are transported to the designated location, the drone body 1 will land. At this time, the motor can start the lead screw 10 to rotate, so that the lead screw 10 drives the slider 11 to move away from the motor. At this time, the slider 11 will drive the push plate 14 to move, so that the push plate 14 pushes the goods in the placement block 4, thereby pushing the goods out of the placement block 4 without manual operation to remove the goods. Afterwards, the drone body 1 can quickly return to home. By controlling the lead screw 10 to reverse, the slider 11 can drive the push plate 14 to reset.

[0043] After loading the goods into the placement block 4, the motor drives the lead screw 10 to reverse. At this time, the slider 11 will slide towards the side closer to the motor, so that the push plate 14 pushes the rectangular block 15, thereby allowing the rectangular block 15 to push the gas in the connecting block 12 from the connecting pipe 27 into the round rod 5. At this time, the gas will push the slide rod 6, so that the slide rod 6 pushes the fixing plate 7, allowing the fixing plate 7 to clamp the goods.

[0044] When the goods enter the placement block 4, they will come into contact with the rotating shaft 18. At this time, the rotating shaft 18 can be used to assist in loading the goods, thereby reducing friction and improving the convenience of loading for the staff. When the drone body 1 is flying, the goods will come into contact with the rotating shaft 18, and the friction will decrease, which will affect the stability of the goods. Therefore, when loading the goods in this application, the repulsion between the magnetic plate 21 and the magnetic block 19 can be used to push the connecting plate 17 so that the height of the rotating shaft 18 is higher than the bottom surface of the inner wall of the placement block 4, allowing the goods to come into contact with the rotating shaft 18. After loading is completed, the slider 11 will move towards the side closer to the motor. At this time, the slider 11 will drive the magnetic plate 21 to move. The length of the connecting groove is longer than the storage groove 16, so that the slider 11 can drive the magnetic block 19 away from the magnetic block 19. At this time, the drive spring 20 will pull the connecting plate 17 downward, so that the rotating shaft 18 no longer comes into contact with the goods, thereby improving the stability of the goods during transportation.

[0045] When the fixing plate 7 clamps the goods, the elastic plate 24 will come into contact with the goods. The elasticity of the elastic plate 24 can protect the goods and prevent the fixing plate 7 from damaging them. When the fixing plate 7 clamps the goods, the moving plate 23 will be pushed by the goods. At this time, the moving plate 23 will push the gas in the moving groove 22, so that the gas enters the elastic plate 24 after passing through the through hole 25 and the connecting hole. At this time, the elastic plate 24 will expand, so that the elastic plate 24 will fit more closely to the goods, thereby improving the protection of the goods.
