Description

Technical Field

[0001] This utility model relates to the technical field of logistics and transportation, and in particular to a low-altitude cargo-carrying unmanned aerial vehicle (UAV). Background Technology

[0002] With the rapid development of the low-altitude economy, drones are increasingly being used in logistics delivery, emergency supplies delivery, and medical sample transportation. Especially in short-distance urban delivery and the transport of goods to remote areas, low-altitude cargo drones are gradually becoming an important supplement to traditional transportation methods due to their flexibility, efficiency, and low cost.

[0003] However, in practical applications, drones are inevitably affected by factors such as airflow disturbances, takeoff and landing impacts, and attitude adjustments during flight, resulting in varying degrees of turbulence, shaking, and even instantaneous acceleration changes. For ordinary goods, such vibrations are acceptable; but for valuable, delicate, or fragile items (such as electronic components, medical reagents, optical instruments, and works of art), even minor collisions or vibrations can cause irreversible damage, seriously affecting transportation safety and reliability.

[0004] Previously, to address the aforementioned issues, the industry commonly employed customized, fully enclosed clamps to secure and cushion items. These clamps typically mimic the design of packaging for household appliances (such as foam molds specifically for televisions and monitors), featuring internal grooves that perfectly match the item's shape and filled with cushioning materials like high-density sponge, EVA foam, or memory foam to achieve comprehensive wrapping and shock absorption. While this method effectively protects items in specific scenarios, it has significant drawbacks: poor versatility. Since each item has different dimensions, custom clamps must be designed separately, leading to long development cycles, high manufacturing costs, and difficulty in adapting to multiple product categories. Therefore, a drone suitable for transporting various valuable items is needed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a low-altitude cargo drone that can protect and fix items of different shapes, is easy to use, highly versatile, and highly practical.

[0006] This utility model discloses a low-altitude cargo-carrying unmanned aerial vehicle (UAV), including a UAV; it also includes a housing A, a housing B, two sets of protective fixing mechanisms, and a connecting mechanism. Both housing A and housing B have chambers. Housing A has an opening at its upper end, and housing B has an opening at its lower end. One set of protective fixing mechanisms is fixedly installed in the chamber of housing A, and the other set of protective fixing mechanisms is symmetrically fixedly installed in the chamber of housing B in the vertical direction. The protective fixing mechanisms have the function of changing shape. A latch is provided between housing A and housing B, and housing A and housing B are connected by the latch. Housing B is connected by the connecting mechanism. It is fixedly installed at the bottom of the drone; when transporting valuables, the items are placed in box A, and then box B is fastened to the top of box A, so that the protective fixing mechanism on box A and box B secures the items. At the same time, box A and box B are fixedly connected by a latch. Then, box B is fixed to the bottom of the drone through the connecting mechanism, and then the drone can be used to transport the items. Because the protective fixing mechanism has the function of changing shape, it can adjust its shape according to the shape of the items to be fixed, and can protect and fix items of different shapes. It is convenient to use, highly versatile, and highly practical.

[0007] Preferably, the connecting mechanism includes a fixed plate, a connecting shaft, and a three-jaw chuck. The fixed plate is fixedly installed on the upper end of the housing B, the connecting shaft is fixedly installed on the upper end of the fixed plate, the upper end of the three-jaw chuck is provided with a mounting plate, the three-jaw chuck is fixedly installed on the lower end of the drone, and the upper part of the connecting shaft is clamped and fixed by the three-jaw chuck. When the item is fixed in housing A and housing B, and housing A and housing B are fastened together, the upper part of the connecting shaft is clamped and fixed by the three-jaw chuck. Then, the drone is made to fly, and the three-jaw chuck drives the connecting shaft, the fixed plate, and housing B to move, which facilitates the connection and fixation between housing B and the drone.

[0008] Preferably, the protective fixing mechanism includes an electromagnet and multiple elastic mechanisms, all of which are mounted on the electromagnet and are elastic. Two electromagnets are respectively fixedly installed in the cavities of box A and box B. When an item is placed, the item comes into contact with the multiple elastic mechanisms on the two electromagnets, thereby causing the elastic mechanisms to change shape and fixing the item through the multiple elastic mechanisms.

[0009] Preferably, the elastic mechanism includes a sliding column, a limiting block, a spring, a base plate, and a silicone pad. The electromagnet has multiple vertically connected grooves. The sliding column is slidably installed in the grooves of the electromagnet. The limiting block is fixedly installed on the sliding column. Both ends of the spring are respectively fixedly installed on the limiting block and the base plate. The limiting block is in close contact with the end of the electromagnet closest to the base plate. The spring is in a compressed state. The silicone pad is fixedly installed on the sliding column, which is made of iron. Multiple base plates on the two sets of protective fixing mechanisms are respectively fixedly installed at the lower end of chamber A and the upper end of chamber B. In chamber A, the upper end of the limiting block is in close contact with the lower end of the electromagnet. In chamber B, the lower end of the limiting block is in close contact with the upper end of the electromagnet. Control buttons on the two electromagnets are located on chamber A and chamber B, respectively. When securing an item, first place the item on top of multiple silicone pads in box A. Then, place box B on top of box A, so that the lower part of the item contacts the silicone pads in box A, and the upper part contacts the silicone pads in box B. Because multiple sliding posts are mounted on electromagnets, the height of the sliding posts in boxes A and B will change according to the shape of the item, ensuring that the upper and lower parts of the item contact the silicone pads respectively. Then, activate the two electromagnets to attract and fix the sliding posts, thus fixing their positions and consequently the positions of the silicone pads, securing the item. Since the height of the silicone pads can be adjusted according to the shape of the item, it can secure items of different shapes, making it highly versatile and practical.

[0010] Preferably, the box B is provided with two handles; this arrangement facilitates the movement of the box B.

[0011] Preferably, the drone is equipped with a lidar; this feature facilitates the drone's avoidance of nearby obstacles.

[0012] Preferably, the drone is equipped with a marker light, which is fixedly installed on the upper part of the drone; this feature improves the drone's visibility, allowing people to quickly locate the drone in dark environments.

[0013] Compared with the prior art, the advantages of this utility model are: it can protect and fix items of different shapes, is convenient to use, highly versatile, and highly practical. Attached Figure Description

Housing B3 is connected by the connecting mechanism. It is fixedly installed at the lower end of the drone 1. When transporting valuables, the items are placed in the box A2, and then the box B3 is fastened to the upper end of the box A2. The protective fixing mechanism on the box A2 and the box B3 secures the items. At the same time, the box A2 and the box B3 are fixedly connected by a buckle. Then, the box B3 is fixed to the lower end of the drone 1 through the connecting mechanism. Then, the drone 1 can transport the items. Since the protective fixing mechanism has the function of changing shape, it can adjust its shape according to the shape of the items to be fixed. It can protect and fix items of different shapes. It is convenient to use, highly versatile, and highly practical.

[0025] like Figure 1 , Figure 4 and Figure 6 The connecting mechanism includes a fixed plate 4, a connecting shaft 5, and a three-jaw chuck 6. The fixed plate 4 is fixedly installed on the upper end of the housing B3, the connecting shaft 5 is fixedly installed on the upper end of the fixed plate 4, and the upper end of the three-jaw chuck 6 is provided with a mounting plate. The three-jaw chuck 6 is fixedly installed on the lower end of the drone 1, and the upper part of the connecting shaft 5 is clamped and fixed by the three-jaw chuck 6. When the item is fixed in the housing A2 and housing B3, and the housing A2 and housing B3 are fastened together, the upper part of the connecting shaft 5 is clamped and fixed by the three-jaw chuck 6. Then, the drone 1 is made to fly, and the three-jaw chuck 6 drives the connecting shaft 5, the fixed plate 4, and the housing B3 to move, which facilitates the connection and fixation between the housing B3 and the drone.

[0026] like Figure 1 , Figure 3 , Figure 5 and Figure 6 The protective fixing mechanism includes an electromagnet 7 and multiple elastic mechanisms. The multiple elastic mechanisms are all installed on the electromagnet 7 and are elastic. The two electromagnets 7 are respectively fixedly installed in the cavities of the box A2 and the box B3. When an item is placed, the item comes into contact with the multiple elastic mechanisms on the two electromagnets 7, thereby causing the elastic mechanisms to change shape and fixing the item through the multiple elastic mechanisms.

[0027] like Figure 3 , Figure 5 , Figure 6 and Figure 7The elastic mechanism includes a sliding column 8, a limiting block 9, a spring 10, a base plate 11, and a silicone pad 12. The electromagnet 7 has multiple vertically connected grooves. The sliding column 8 is slidably installed in the grooves of the electromagnet 7.

The control buttons on the two electromagnets 7 are located in chambers A2 and B3, respectively. On box B3; when securing an item, first place the item on top of the multiple silicone pads 12 in box A2, then cover box A2 with box B3, so that the lower part of the item contacts the multiple silicone pads 12 in box A2, and the upper part of the item contacts the multiple silicone pads 12 in box B3. Since multiple sliding posts 8 are mounted on electromagnets 7, the height of the sliding posts 8 in box A2 and box B3 will change according to the shape of the item, so that the upper and lower parts of the item contact the multiple silicone pads 12 respectively. Then, turn on the two electromagnets 7, so that the two electromagnets 7 attract and fix the multiple sliding posts 8, fix the position of the multiple sliding posts 8, and thus fix the position of the multiple silicone pads 12, thereby fixing the item with the multiple silicone pads 12. Since the height of the multiple silicone pads 12 can be adjusted according to the shape of the item, it can fix items of different shapes, making it highly versatile and practical.
