Detailed Description of the Embodiment

[0024] The following further describes the utility model in detail with reference to the embodiments:

[0025] Embodiment 1

[0026] As Figures 1-5As shown in the figure, the utility model provides a low-altitude transportation unmanned aerial vehicle, which includes an unmanned aerial vehicle body 1. A shock absorption mechanism 2 is arranged on the bottom surface of the unmanned aerial vehicle body 1. A clamping mechanism 3 is arranged on the bottom surface of the unmanned aerial vehicle body 1. A loading mechanism 4 is arranged on the bottom surface of the clamping mechanism 3. The clamping mechanism 3 includes a top plate 31. A connecting rod 32 is fixedly connected to the bottom surface of the top plate 31. One end of the connecting rod 32 is fixedly connected to a bottom plate 33. A telescopic machine 34 is fixedly connected to the top surface of the bottom plate 33. The output end of the telescopic machine 34 is clamped with a fixed cylinder 35. A pull rod 36 is fixedly connected to the side surface of the fixed cylinder 35. The number of the pull rods 36 is three. One end of the pull rod 36 is rotatably connected to a connecting rod 37. A rotating buckle 38 is fixedly connected to the side surface of the bottom plate 33. The number of the rotating buckles 38 is three and they are evenly distributed on the side surface of the bottom plate 33. A clamping plate 39 is rotatably connected to the inside of the rotating buckle 38. One end of the connecting rod 37 is rotatably connected to the clamping plate 39.

[0027] In this embodiment, when in use, the telescopic machine 34 is started. The output shaft of the telescopic machine 34 contracts and drives the pull rod 36 to move downward through the fixed cylinder 35. The movement of the pull rod 36 drives the connecting rod 37 to rotate and move downward. The movement of the connecting rod 37 drives the clamping plate 39 to rotate in the rotating buckle 38. The rotation of the clamping plate 39 fixes the loading device, which is convenient for transporting items. After use, the telescopic machine 34 can be started to drive the pull rod 36 to move upward through the fixed cylinder 35. The pull rod 36 drives the clamping plate 39 to rotate through the connecting rod 37. The rotation of the clamping plate 39 releases the loading device.

[0028] Embodiment 2

[0029] As Figures 1-5 shown, on the basis of Embodiment 1, the utility model provides a technical solution: Preferably, the shock absorption mechanism 2 includes a support cylinder 21. A spring 22 is fixedly connected to the inside of the support cylinder 21. One end of the spring 22 is fixedly connected to a connecting plate 23. A telescopic column 24 is fixedly connected to the bottom surface of the connecting plate 23. One end of the telescopic column 24 penetrates through the bottom surface of the support cylinder 21. One end of the telescopic column 24 is inserted with a connecting ring 25. A bottom rod 26 is fixedly connected to the bottom surface of the connecting ring 25. The connecting rings 25 are in groups of two. One bottom rod 26 is fixedly connected to two connecting rings 25. The two connecting rings 25 are evenly distributed at both ends of the top surface of the bottom rod 26.

[0030] In this embodiment, the unmanned aerial vehicle body 1 is supported by the bottom rod 26. When the unmanned aerial vehicle body 1 lands, it drives the support cylinder 21 to move downward. The support cylinder 21 drives the spring 22 to contract downward. The length of the telescopic column 24 entering the support cylinder 21 increases. The force when the unmanned aerial vehicle body 1 falls is weakened by the spring 22, preventing damage to the unmanned aerial vehicle body 1 due to excessive force when falling. When the unmanned aerial vehicle body 1 takes off, it drives the bottom rod 26 to leave the ground. The spring 22 expands and drives the distance of the telescopic column 24 in the support cylinder 21 to decrease.

[0031] Embodiment 3

[0032] As Figures 1-5 Figures 1-5 shows, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the loading mechanism 4 includes a fixing plate 41. The bottom surface of the fixing plate 41 is fixedly connected with a loading box 42. The side surface of the loading box 42 is fixedly connected with a hinge 43. One end of the hinge 43 is fixedly connected with a closing plate 44. The side surface of the closing plate 44 is fixedly connected with a handle 45. The inside of the loading box 42 is fixedly connected with a slide rail 46. The side surface of the slide rail 46 is slidably connected with a slide plate 47. The top surface of the slide plate 47 is provided with a fixing groove 471. The side surface of the fixing groove 471 is fixedly connected with a return spring 472. The inside of the fixing groove 471 is slidably connected with a moving plate 473. The number of the moving plates 473 is two. One end of the return spring 472 is fixedly connected with the moving plate 473. One moving plate 473 is fixedly connected with two return springs 472.

[0033] In this embodiment, the loading box 42 is fixed below the unmanned aerial vehicle body 1 by the cooperation of the fixing plate 41 and the clamping plate 39. During transportation, the handle 45 is pulled to drive the closing plate 44 to rotate. The closing plate 44 rotates to open one side of the loading box 42. The slide plate 47 is pulled to make the slide plate 47 slide out of the loading box 42. The moving plate 473 is pulled to drive the return spring 472 to contract. The item to be transported is placed on the slide plate 47. The moving plate 473 is released. The return spring 472 expands to drive the moving plate 473 to clamp the transported item, preventing the item from shaking during transportation and causing damage to the unmanned aerial vehicle body 1 due to the imbalance of the unmanned aerial vehicle body 1.

[0034] Next, the working principle of the low-altitude transportation unmanned aerial vehicle will be specifically described.

[0035] As Figures 1-5As shown in the figure, the drone body 1 is supported by the bottom rod 26. When the drone body 1 lands, it drives the support cylinder 21 to move downward. The support cylinder 21 drives the spring 22 to contract downward. The length of the telescopic column 24 entering the support cylinder 21 increases. The spring 22 reduces the force on the drone body 1 when it falls, preventing the drone body 1 from being damaged due to excessive force when it falls. Start the telescopic machine 34. The output shaft of the telescopic machine 34 contracts and drives the pull rod 36 to move downward through the fixed cylinder 35. The movement of the pull rod 36 drives the connecting rod 37 to rotate and move downward. The movement of the connecting rod 37 drives the clamping plate 39 to rotate in the rotary buckle 38. The rotation of the clamping plate 39 fixes the fixing plate 41. Pull the handle 45 to drive the closing plate 44 to rotate. The rotation of the closing plate 44 opens one side of the loading box 42. Pull the sliding plate 47 to make the sliding plate 47 slide out of the loading box 42. Pull the moving plate 473 to drive the return spring 472 to contract. Place the item to be transported on the sliding plate 47. Release the moving plate 473. The relaxation of the return spring 472 drives the moving plate 473 to clamp the transported item. Push the sliding plate 47 into the loading box 42. Pull the handle 45 to drive the closing plate 44 to rotate to close the loading box 42. Start the drone body 1, which can drive the loading box 42 to fly to transport the item.

[0036] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
