[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-8 The figure shows an aerial load-carrying and object-delivering device based on a drone, comprising a device shell 1, a drone body 2 being detachably mounted on the top of the device shell 1, a cavity 3 being opened inside the device shell 1, the cavity 3 opening downward, a telescopic mechanism being arranged inside the cavity 3, a suction cup 27 being arranged on one side of the device shell 1, the suction cup 27 being connected to the device shell 1 through an adjusting mechanism, a bottom plate 13 being arranged below the device shell 1, a supporting plate 16 being slidably mounted above the bottom plate 13, the supporting plate 16 being connected to the bottom plate 13 through a movable structure, rotating rods 20 being rotatably mounted on both sides above the supporting plate 16, the rotating rod 20 being arranged horizontally, the central axis of the rotating rod 20 being parallel to the central axis of the suction cup 27, a baffle 21 being fixedly sleeved on the outer surface of the rotating rod 20, a connecting rope 23 being fixedly mounted above the baffle 21, a rotatable reel 22 being arranged inside the cavity 3, and the end of the connecting rope 23 away from the baffle 21 being wound around the outer surface of the reel 22.

[0022] The mobile structure includes a mobile trolley 19, which is fixedly installed below the supporting plate 16. The mobile trolley 19 contacts the upper end surface of the base plate 13. A groove 18 is provided below the supporting plate 16. A track 17 is fixedly installed above the base plate 13 and the baffle 21. The track 17 and the groove 18 are slidably connected.

[0023] Specifically, the drone body 2 can be detachably mounted on top of the device casing 1. The drone body 2 can adopt existing drones of different models, making the device more widely applicable. The items are placed on top of the bottom plate 13, and the telescopic mechanism drives the bottom plate 13 to move up and down under the device casing 1. When the bottom plate 13 contacts the bottom of the device casing 1, the items are located inside the cavity 3. The device casing 1 can provide a certain degree of protection for the items, so that in rainy and snowy weather, when the drone delivers items, the items will not be wetted by rain and snow. The thermal insulation film is adhered to the inside of the device casing 1 as needed, which can keep the items inside the cavity 3 warm, which is beneficial to reduce the impact of high and low temperatures on the items.

[0024] Under the action of the adjusting mechanism, the adjusting structure drives the suction cup 27 to move, so that the suction cup 27 can be adsorbed on the window glass, thereby limiting the device housing 1, which is beneficial to increasing the stability of the drone. At this time, the telescopic mechanism drives the object to move downward through the bottom plate 13. At the same time, the reel 22 rotates, and the reel 22 unwinds the connecting rope 23. The baffle 21 and the bottom plate 13 are in a vertical state. When the bottom 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 bottom plate 13 are on the same horizontal line. At this time, the moving trolley 19 can drive the supporting plate 16 to move The support plate 16 drives the items to move to the open window, which is convenient for the user to pick up the items while standing by the window. For windows without glass around them, the suction cup 27 does not need to be adsorbed, and the bottom plate 13 is directly lowered. The baffle 21 and the bottom plate 13 are on the same horizontal line. At this time, the drone body 2 adjusts the position of the device so that one group of baffles 21 can be placed on the edge of the windowsill. When the support plate 16 drives the items to move above the baffle 21, the items have little effect on the stability of the drone body 2. After the user takes the items away, the bottom plate 13 will not be unbalanced by gravity.

[0025] Furthermore, the drone body 2 can directly stop in mid-air. At this time, the suction cup 27 does not need to be adsorbed, and the bottom plate 13 is directly raised and lowered in front of the user so that the baffle 21 and the bottom plate 13 are parallel, and the user can directly pick up the items.

[0026] The telescopic mechanism includes a support plate 4, and the number of the support plates 4 is at least two groups. The two groups of support plates 4 are cross-arranged, and a connecting shaft 8 is installed at the center of the two groups of support plates 4 for common rotation. Both ends of the support plate 4 are rotatably installed with a shaft 7. A driving assembly is provided above the support plate 4, and the support plate 4 is connected to the base plate 13 through a sliding structure.

[0027] The sliding structure includes a guide groove 14 and a guide block 15 . The guide groove 14 is provided on both sides of the bottom plate 13 . 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 .

[0028] The driving assembly includes two groups of push plates 9 , which are connected to the device housing 1 through a translation structure. The push plates 9 are rotatably installed above the support plate 4 through the shaft 7 , and a power structure is provided between the two groups of push plates 9 .

[0029] The translation structure includes a slide groove 5 and a slider 6. The slide groove 5 is opened on the upper part of the inner portion of the device housing 1. The slider 6 is slidably installed inside the slide groove 5. The slider 6 and the push plate 9 are fixedly connected.

[0030] The power structure includes a rotating shaft 10, which is rotatably installed inside the device housing 1. The rotating shaft 10 is horizontally arranged, and the axis of the rotating shaft 10 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, and the output end of the motor 12 passes through the device housing 1 and extends to 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.

[0031] Specifically, the motor 12 is connected to an external power supply, 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 groups of push plates 9 to move closer to or away from each other when it rotates. The push plate 9 drives the upper end of the support plate 4 to move synchronously through the shaft 7, and the two groups 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 groups of push plates 9 move away from each other, the bottom plate 13 moves upward, and when the two groups of push plates 9 approach each other, the bottom plate 13 moves downward.

[0032] The reel 22 is fixedly sleeved on the outer surface of the rotating shaft 10, and a fixed block 25 is provided between the reel 22 and the push plate 9. The fixed block 25 is fixedly connected to the device housing 1, and a spring 24 is movably sleeved on the outer surface of the rotating shaft 10. The spring 24 is located between the fixed block 25 and the push plate 9.

[0033] When the rotating shaft 10 rotates, it drives the two groups of push plates 9 closer to each other. At this time, the reel 22 unwinds the connecting rope 23. When the push plate 9 moves out of the range of the thread groove 11, the spring 24 pushes the two groups of push plates 9 closer to each other. At this time, the push plate 9 and the rotating shaft 10 are rotated and connected, so that the rotating shaft 10 can drive the reel 22 to continue to unwind the connecting rope 23. When the item is taken away, the reel 22 reels the connecting rope 23, so that the baffle 21 can be rotated to be perpendicular to the bottom plate 13, and the connecting rope 23 pulls the baffle 21 to move upward, so that the two groups of push plates 9 can move into the range of the thread groove 11 again, and the thread groove 11 can drive the two groups of push plates 9 away from each other.

[0034] The adjusting mechanism includes a piston cylinder 26, which is arranged 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 fixed plate 29. A mounting plate 30 is rotatably installed at the upper center 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.

[0035] A water tank 31 is fixedly installed above the device housing 1, and a water inlet 32 ​​is opened on one side of the water tank 31. A water outlet pipe 33 is fixedly installed above 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 close to the suction cup 27.

[0036] Specifically, water is injected into the water tank 31 through the water 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 toward the glass, and the connecting pipe 34 transports the water inside the water tank 31 to the inside of the water outlet pipe 33 and sprays it onto the surface of the glass through the nozzle 35, so that the glass and the suction cup 27 are adsorbed more closely. 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.

[0037] Working principle: The drone body 2 can be detachably mounted on top of the device casing 1. The drone body 2 can adopt existing drones of different models, making the device more widely applicable. The items are placed on top of the bottom plate 13. When the bottom plate 13 contacts the bottom of the device casing 1, the items are located inside the cavity 3. The device casing 1 can provide a certain degree of protection for the items, so that in rainy and snowy weather, when the drone delivers items, the items will not be wetted by rain and snow. The thermal insulation film is adhered to the inside of the device casing 1 as needed, which can keep the items inside the cavity 3 warm, which is beneficial to reduce the impact of high and low temperatures on the items.

[0038] 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 groups of push plates 9 to move closer to or away from each other when it rotates. The push plate 9 drives the upper end of the support plate 4 to move synchronously through the shaft 7. The two groups 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 groups of push plates 9 move away from each other, the bottom plate 13 moves upward, and when the two groups of push plates 9 approach each other, the bottom plate 13 moves downward.

[0039] When the shaft 10 rotates, it drives the two sets of push plates 9 to approach each other. At this time, the reel 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 to approach each other. At this time, the push plate 9 and the shaft 10 are rotated and connected, and the bottom plate 13 stops moving, so that the shaft 10 can drive the reel 22 to continue to unwind the connecting rope 23. The baffle 21 rotates around the rotating rod 20 to a horizontal state. The baffle 21 and the bottom plate 13 are on the same horizontal line. At this time, the mobile trolley 19 can drive the supporting plate 16 to move, so that the track 17 slides inside the groove 18. The supporting plate 16 drives the items to move, and the items move to the open window, which is convenient for the user to stand by the window to take the items. After the items are taken away The drum 22 reels the connecting rope 23 so that the baffle 21 can be rotated to be perpendicular to the bottom plate 13. The connecting rope 23 pulls the baffle 21 upward so that the two sets of push plates 9 can move again within the range of the thread groove 11. The thread groove 11 can drive the two sets of push plates 9 to move away from each other. For windows without glass around, the suction cup 27 does not need to be adsorbed and the bottom plate 13 is directly lowered. The baffle 21 and the bottom 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 be placed on the edge of the windowsill. When the supporting plate 16 drives the items to move above the baffle 21, the items have little effect on the stability of the drone body 2. After the user takes the items away, the bottom plate 13 will not be unbalanced by gravity.

[0040] Furthermore, the drone body 2 can directly stop in mid-air. At this time, the suction cup 27 does not need to be adsorbed, and the bottom plate 13 is directly raised and lowered in front of the user so that the baffle 21 and the bottom plate 13 are parallel, and the user can directly pick up the items.

[0041] At the same time, water is injected into the water tank 31 through the water 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 toward the glass, and the connecting pipe 34 transports the water inside the water tank 31 to the inside of the water outlet pipe 33 and sprays it onto the surface of the glass through the nozzle 35, so that the glass and the suction cup 27 are adsorbed more closely. 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.
