[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 The diagram illustrates an aerial cargo delivery device based on a drone, comprising a device housing 1, a drone body 2 detachably mounted on the top of the device housing 1, a cavity 3 with its opening facing downwards inside the device housing 1, a telescopic mechanism inside the cavity 3, a suction cup 27 on one side of the device housing 1 connected to the device housing 1 via an adjustment mechanism, a base plate 13 below the device housing 1, a support plate 16 slidably mounted on the top of the base plate 13, the support plate 16 connected to the base plate 13 via a movable structure, rotating rods 20 rotatably mounted on both sides above the support plate 16, the rotating rods 20 being horizontally positioned, the central axis of the rotating rods 20 being parallel to the central axis of the suction cup 27, a baffle 21 fixedly fitted on the outer surface of the rotating rods 20, a connecting rope 23 fixedly mounted on the top of the baffle 21, a rotatable drum 22 inside the cavity 3, and the end of the connecting rope 23 away from the baffle 21 wound around the outer surface of the drum 22.

[0030] The movable structure includes a movable trolley 19, which is fixedly installed below the support plate 16. The movable trolley 19 is in contact with the upper surface of the base plate 13. A groove 18 is provided below the support plate 16. Tracks 17 are fixedly installed above the base plate 13 and the baffle 21. The tracks 17 and the groove 18 are slidably connected.

[0031] Specifically, the main body 2 of the drone can be detachably installed on top of the outer shell 1 of the device. The main body 2 of the drone can be any of the existing drone models, making the device more widely applicable. The item is placed on top of the base plate 13, and the telescopic mechanism drives the base plate 13 to move up and down below the outer shell 1 of the device. When the base plate 13 and the lower part of the outer shell 1 of the device are in contact, the item is located inside the cavity 3. The outer shell 1 of the device can provide a certain degree of protection for the item, so that the item will not get wet when the drone delivers the item in rainy or snowy weather. As needed, the heat insulation film can be adhered to the inside of the outer shell 1 of the device to keep the item inside the cavity 3 warm, which helps to reduce the impact of high and low temperatures on the item.

[0032] Under the action of the adjustment mechanism, the adjustment structure drives the suction cup 27 to move, so that the suction cup 27 can be attached to the window glass, thereby limiting the device shell 1 and increasing the stability of the drone. At this time, the telescopic mechanism drives the object to move downward through the base plate 13. At the same time, the drum 22 rotates and unwinds the connecting rope 23. The baffle 21 and the base plate 13 are in a vertical state. When the base plate 13 stops moving, the connecting rope 23 continues to unwind, and the baffle 21 rotates around the rotating rod 20 to a horizontal state. The baffle 21 and the base plate 13 are on the same horizontal line. At this time, the moving trolley 19 can drive the support plate 16 to move. The movement causes the track 17 to slide inside the groove 18, and the support plate 16 moves the item. The item moves to the open window, making it easy for the user to stand by the window and pick it up. For windows without surrounding glass, the suction cup 27 does not need to adhere and can directly lower the base plate 13. The baffle 21 and the base plate 13 are on the same horizontal line. At this time, the drone body 2 adjusts the position of the device so that one of the baffles 21 can rest on the edge of the window. When the support plate 16 moves the item above the baffle 21, the item has little impact on the stability of the drone body 2. After the user takes the item away, the base plate 13 will not lose its balance due to gravity.

[0033] Furthermore, the main body of the drone 2 can hover directly in mid-air. At this time, the suction cup 27 does not need to adhere, and the base plate 13 can be raised and lowered directly in front of the user, so that the baffle 21 and the base plate 13 are parallel, and the user can directly pick up the items.

[0034] The telescopic mechanism includes a support plate 4, and there are at least two sets of support plates 4. The two sets of support plates 4 are arranged crosswise. A connecting shaft 8 is rotatably installed at the center of the two sets of support plates 4. Shafts 7 are rotatably installed at both ends of the support plate 4. A drive assembly is provided above the support plate 4. The support plate 4 is connected to the base plate 13 through a sliding structure.

[0035] The sliding structure includes a guide groove 14 and a guide block 15. The guide groove 14 is opened on both sides of the base plate 13, and the guide block 15 is slidably installed inside the guide groove 14. The guide block 15 is rotatably connected to the lower end of the support plate 4 through the shaft 7.

[0036] The drive assembly includes push plates 9, and there are two sets of push plates 9. The push plates 9 are connected to the housing 1 of the device through a translation structure. The push plates 9 are rotatably mounted on the support plate 4 through the shaft 7. A power structure is provided between the two sets of push plates 9.

[0037] The translation structure includes a slide 5 and a slider 6. The slide 5 is opened inside the upper part of the device housing 1, and the slider 6 is slidably installed inside the slide 5. The slider 6 and the push plate 9 are fixedly connected.

[0038] The power structure includes a rotating shaft 10, which is rotatably installed inside the device housing 1. The rotating shaft 10 is horizontally positioned, and its axis is perpendicular to the axis of the rotating rod 20. A threaded groove 11 is provided on the outer surface of the rotating shaft 10, and the threaded groove 11 is threadedly connected to the push plate 9. A motor 12 is fixedly installed on one side of the device housing 1. The output end of the motor 12 passes through the device housing 1 and extends into the interior of the device housing 1. The output end of the motor 12 is fixedly connected to one end of the rotating shaft 10.

[0039] Specifically, the motor 12 is connected to an external power source, and the motor 12 drives the rotating shaft 10 to rotate. Since the threaded groove 11 on the outer surface of the rotating shaft 10 is threadedly connected to the push plate 9, the rotating shaft 10 can drive the two sets of push plates 9 to move closer or further apart when rotating. The push plates 9 drive the upper end of the support plate 4 to move synchronously through the shaft 7. The two sets of support plates 4 rotate around the connecting shaft 8. At the same time, the support plate 4 can drive the guide block 15 to slide inside the guide groove 14 through the shaft 7. When the two sets of push plates 9 move away from each other, the bottom plate 13 moves upward. When the two sets of push plates 9 move closer to each other, the bottom plate 13 moves downward.

[0040] The drum 22 is fixedly sleeved on the outer surface of the rotating shaft 10. A fixing block 25 is provided between the drum 22 and the push plate 9. The fixing block 25 is fixedly connected to the outer shell 1 of the device. A spring 24 is movably sleeved on the outer surface of the rotating shaft 10. The spring 24 is located between the fixing block 25 and the push plate 9.

[0041] When the rotating shaft 10 rotates, it causes the two sets of push plates 9 to move closer to each other. At this time, the drum 22 unwinds the connecting rope 23. When the push plate 9 moves out of the range of the threaded groove 11, the spring 24 pushes the two sets of push plates 9 closer to each other. At this time, the push plate 9 and the rotating shaft 10 rotate and connect, so that the rotating shaft 10 can drive the drum 22 to continue unwinding the connecting rope 23. When the item is removed, the drum 22 winds up the connecting rope 23, so that the baffle 21 can rotate to be perpendicular to the bottom plate 13. The connecting rope 23 pulls the baffle 21 to move upward, so that the two sets of push plates 9 can move back into the range of the threaded groove 11. The threaded groove 11 can drive the two sets of push plates 9 to move away from each other.

[0042] The adjustment mechanism includes a piston cylinder 26, which is disposed between the device housing 1 and the suction cup 27. The piston cylinder 26 and the suction cup 27 are fixedly connected. A piston plate 28 is slidably installed inside the piston cylinder 26. The side of the piston plate 28 away from the suction cup 27 is fixedly connected to the device housing 1 through a fixing plate 29. An mounting plate 30 is rotatably installed at the center of the top of the piston cylinder 26. The end of the mounting plate 30 away from the piston cylinder 26 is rotatably connected to the push plate 9.

[0043] A water tank 31 is fixedly installed on the top of the device housing 1. A water inlet 32 ​​is opened on one side of the water tank 31. A water outlet pipe 33 is fixedly installed on the top of the piston cylinder 26. The water outlet pipe 33 is connected to the water tank 31 through a connecting pipe 34. A nozzle 35 is fixedly installed on the side of the water outlet pipe 33 near the suction cup 27.

[0044] Specifically, water is injected into the water tank 31 through the inlet 32. When the two sets of push plates 9 approach each other, they can drive the mounting plate 30 to rotate, thereby pushing the piston cylinder 26 to slide on the outer surface of the fixed plate 29. At this time, the piston cylinder 26 drives the suction cup 27 to move towards the glass. The connecting pipe 34 transports the water inside the water tank 31 to the inside of the outlet pipe 33 and sprays it onto the surface of the glass through the nozzle 35, making the glass and the suction cup 27 adhere more tightly. When the suction cup 27 contacts the glass, the mounting plate 30 can also push the device housing 1 to move away from the suction cup 27. At this time, the device housing 1 drives the piston plate 28 to move through the fixed plate 29. The piston plate 28 extracts the air between the suction cup 27 and the glass, further increasing the tightness of the connection between the suction cup 27 and the glass.

[0045] Working principle: The main body 2 of the drone can be detachably installed on the top of the outer shell 1 of the device. The main body 2 of the drone can be different models of existing drones, making the application range of the device wider. When the item is placed on the bottom plate 13, the item is located inside the cavity 3 when the bottom plate 13 is in contact with the bottom of the outer shell 1 of the device. The outer shell 1 of the device can provide a certain degree of protection for the item, so that the item will not get wet when the drone delivers the item in rainy or snowy weather. As needed, the heat insulation film can be adhered to the inside of the outer shell 1 of the device to keep the item inside the cavity 3 warm, which helps to reduce the impact of high and low temperatures on the item.

[0046] Connect motor 12 to an external power source. Motor 12 drives shaft 10 to rotate. Since the threaded groove 11 on the outer surface of shaft 10 is threadedly connected to push plate 9, shaft 10 can drive two sets of push plates 9 to move closer or further apart when rotating. Push plate 9 drives the upper end of support plate 4 to move synchronously through shaft 7. Two sets of support plates 4 rotate around connecting shaft 8. At the same time, support plate 4 can drive guide block 15 to slide inside guide groove 14 through shaft 7. When two sets of push plates 9 move away from each other, bottom plate 13 moves upward. When two sets of push plates 9 move closer to each other, bottom plate 13 moves downward.

[0047] When the rotating shaft 10 rotates, it causes the two sets of push plates 9 to move closer together. At this time, the drum 22 unwinds the connecting rope 23. When the push plates 9 move out of the range of the threaded groove 11, the spring 24 pushes the two sets of push plates 9 closer together. At this time, the push plates 9 and the rotating shaft 10 are rotated and connected. The base plate 13 stops moving, so that the rotating shaft 10 can drive the drum 22 to continue unwinding the connecting rope 23. The baffle 21 rotates around the rotating rod 20 to a horizontal state. The baffle 21 and the base plate 13 are on the same horizontal line. At this time, the moving trolley 19 can drive the support plate 16 to move, so that the track 17 slides inside the groove 18. The support plate 16 moves the item. The item moves to the open window, making it convenient for the user to stand by the window and take the item. After the item is taken away... The drum 22 winds up the connecting rope 23, allowing the baffle 21 to rotate to be perpendicular to the base plate 13. The connecting rope 23 pulls the baffle 21 upward, allowing the two sets of push plates 9 to move back into the range of the threaded groove 11. The threaded groove 11 can drive the two sets of push plates 9 away from each other. For windows without surrounding glass, the suction cup 27 does not need to adhere and directly lowers the base plate 13. The baffle 21 and the base plate 13 are on the same horizontal line. At this time, the drone body 2 adjusts the position of the device so that one set of baffles 21 can rest on the edge of the windowsill. When the support plate 16 moves the item above the baffle 21, the item has little impact on the stability of the drone body 2. After the user removes the item, the base plate 13 will not lose its balance due to gravity.

[0048] Furthermore, the main body of the drone 2 can hover directly in mid-air. At this time, the suction cup 27 does not need to adhere, and the base plate 13 can be raised and lowered directly in front of the user, so that the baffle 21 and the base plate 13 are parallel, and the user can directly pick up the items.

[0049] Meanwhile, water is injected into the water tank 31 through the inlet 32. When the two sets of push plates 9 approach each other, they can drive the mounting plate 30 to rotate, thereby pushing the piston cylinder 26 to slide on the outer surface of the fixed plate 29. At this time, the piston cylinder 26 drives the suction cup 27 to move towards the glass. The connecting pipe 34 transports the water inside the water tank 31 to the inside of the outlet pipe 33 and sprays it onto the surface of the glass through the nozzle 35, making the glass and the suction cup 27 adhere more tightly. When the suction cup 27 contacts the glass, the mounting plate 30 can also push the device housing 1 to move away from the suction cup 27. At this time, the device housing 1 drives the piston plate 28 to move through the fixed plate 29. The piston plate 28 extracts the air between the suction cup 27 and the glass, further increasing the tightness of the connection between the suction cup 27 and the glass.
