[0002] With the rapid development of e-commerce at home and abroad, the demand for logistics and express delivery is showing explosive growth. Traditional logistics transportation methods have limitations such as low transportation efficiency, high labor costs, and poor adaptability to complex terrain. In this context, unmanned aerial vehicle logistics transportation, with its flexibility, speed, and low labor costs, has gradually become the focus of the logistics industry. Unmanned aerial vehicles not only can quickly shuttle in narrow streets in cities and rural areas, but also can easily cross complex terrains such as mountains and rivers, providing an efficient, flexible, and economical solution for logistics transportation. Currently, unmanned aerial vehicles still have the disadvantage of insufficient automation in the express delivery industry. In the process of loading and unloading express cargo by unmanned aerial vehicles, human intervention is still required to a large extent, which greatly affects the efficiency of unmanned aerial vehicle logistics transportation.

DETAILED DESCRIPTION

[0027] The application will be further described in detail below with reference to the drawings.

[0028] As Figures 1 to 10 shown, the structure and function of a device for unmanned aerial vehicle transportation and automatic delivery of a cargo box will be described in detail below;

[0029] A device for unmanned aerial vehicle transportation and automatic delivery of a cargo box, comprising a delivery frame 11, both sides of the delivery frame 11 are fixedly connected with mounting brackets 21, two cargo box flaps 23 are rotatably connected on each mounting bracket 21, and four cargo box flaps 23 are located at the bottom of the delivery frame 11.

[0030] In use, as Figure 1 shown, the goods to be transported are placed in the delivery frame 11, and the four cargo box flaps 23 support the bottom of the goods, the mounting bracket 21 is provided with a rotary rudder 22 for driving the cargo box flap 23 to rotate, when the goods need to be delivered, the rotary rudder 22 is started, the output shaft of the rotary rudder 22 drives the cargo box flap 23 to rotate, so that the cargo box flap 23 no longer supports the bottom of the goods, and then the goods fall out of the delivery frame 11, completing the delivery of the goods.

[0031] Further, the mounting bracket 21 is fixedly connected with a connecting bracket 31, the delivery frame 11 is installed at the bottom of the unmanned aerial vehicle through the connecting bracket 31, thereby completing the connection of the unmanned aerial vehicle and the delivery frame 11, and the goods are transported by the unmanned aerial vehicle.

[0032] Further, in order to ensure the stability of the goods during transportation and delivery;

[0033] The delivery frame 11 is fixedly connected with four mounting seats 41, each mounting seat 41 is fixedly connected with a limiting column 42, and each limiting column 42 is provided with a threaded groove 43.

[0034] The limiting column 42 is gap-fitted with a rotating sleeve 44, a torsional spring is fixedly connected between the rotating sleeve 44 and the mounting seat 41, the inner side of the rotating sleeve 44 is fixedly connected with a moving ball 441, and the moving ball 441 is slidingly connected in the threaded groove 43.

[0035] The rotating sleeve 44 is fixedly connected with a swing arm 45, and the lifting plate 46 is slidingly connected between the two swing arms 45 on the same side.

[0036] The inner side of the delivery frame 11 is fixedly connected with two sliding rails 12, the lifting plate 46 is fixedly connected with a sliding column 53, the sliding column 53 is slidably connected with a sliding cylinder 52, the sliding cylinder 52 is fixedly connected with a sliding seat 51, and the sliding seat 51 is slidably connected on the sliding rail 12;

[0037] The lifting plate 46 is threadedly connected with two threaded rods 47, and the ends of the two threaded rods 47 are rotatably connected to the bottom plate 48;

[0038] The bottom plate 48 is slidably connected with a clamping plate 49, and the clamping plate 49 and the bottom plate 48 are fixedly connected with a compression spring;

[0039] When in use, the goods to be transported are placed between the two clamping plates 49, and the clamping surface of the clamping plate 49 is obliquely arranged, so as to guide the goods and facilitate the placement of the goods between the two clamping plates 49. When the goods are placed between the two clamping plates 49, the two clamping plates 49 move outward under the pushing of the goods, so that the clamping plate 49 extrudes the compression spring, and the two clamping plates 49 extrude and fix the goods under the reaction force of the compression spring, so as to ensure the stability of the goods during transportation;

[0040] When the four box stop pieces 23 no longer support the bottom of the goods, the goods move downward under the action of gravity, the clamping plate 49 moves downward under the action of the goods, the bottom plate 48 moves downward under the action of the clamping plate 49, and the lifting plate 46 moves downward under the action of the bottom plate 48. The lifting plate 46 can only move up and down under the limiting of the sliding seat 51, the sliding cylinder 52 and the sliding column 53, so that the inner end of the two swing arms 45 moves downward, i.e. the inner end of the two swing arms 45 swings downward, the swing arm 45 drives the rotating sleeve 44 to rotate, so that the rotating sleeve 44 moves on the limiting column 42, the moving ball 441 slides in the threaded groove 43, the threaded groove 43 guides the moving ball 441, and the swing arm 45 moves away from the goods while the rotating sleeve 44 rotates, so that the clamping plate 49 moves away from the goods, and the clamping plate 49 gradually releases the clamping of the goods during the downward movement of the goods. During the falling process of the goods, the torsional spring is extruded, the reaction force generated by the torsional spring enables the goods to fall stably on the ground. At the same time, the clamping plate 49 releases the clamping of the goods, the clamping plate 49 and the goods are separated due to the take-off of the unmanned aerial vehicle, the torsional spring returns to the original position after the gravity of the goods disappears, the swing arm 45 returns to the original position, the clamping plate 49 returns to the original position under the action of the swing arm 45, the box stop piece 23 returns to the original position under the action of the rotary rudder 22, and the next movement is facilitated;

[0041] It should be noted that, here when the cargo box baffle 23 no longer support the goods, the gravity of the goods is changed into two clamping plate 49 clamping, swing arm 45 slows down the falling speed of the goods, the goods fall to the ground, the unmanned aerial vehicle takes off, alone by clamping plate 49 is unable to clamp goods, clamping plate 49 and the goods between a certain slip, further make the clamping plate 49 can reset and goods separate, after taking off the unmanned aerial vehicle, the clamping plate 49 reset;

[0042] Further, in order to adjust the clamping force of the clamping plate 49 on the goods, and also to adapt to the clamping of different size goods, rotate the threaded rod 47, the threaded rod 47 rotates through the thread to drive the bottom plate 48 to move, thereby adjusting the relative distance between the bottom plate 48 and the lifting plate 46, adjusting the clamping force of the clamping plate 49 on the goods, and adapting to the clamping of different size goods.
