[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0030] like Figures 1 to 5 As shown, a low-altitude transport drone according to one embodiment of this utility model includes a loading box 1, a cargo box 2 installed inside the loading box 1, a hinge post 21 integrally formed on the cargo box 2, and a hinge hole 11 matching the hinge post 21 on the loading box 1. The cargo box 2 is hinged to the loading box 1 through the hinge post 21, and a lubricating layer is provided on the upper surface of the cargo box 2. A lifting assembly is installed on the cargo box 2, and the lifting assembly is installed at the end of the cargo box 2 away from the hinge post 21.
[0031] Specifically, when transporting goods, the goods are placed inside the cargo box 2. After the low-altitude transport drone transports the goods to the destination, the lifting component lifts them upwards, and the cargo box 2 rotates around the hinge column 21. The goods inside the cargo box 2 then slide out and fall to the outside of the loading container 1, eliminating the need for workers to wait for unloading. The goods placed inside the cargo box 2 are protected without incurring additional labor and time costs.
[0032] In addition, one end of the loading box 1 is arc-shaped, which reduces wind resistance, saves power, and increases the range of the low-altitude transport drone when it flies.
[0033] Preferably, the lubricating layer on the upper surface of the storage box 2 is a Teflon layer. Teflon is a polymer material with a very low coefficient of friction, which ensures that the items inside the storage box 2 can slide down smoothly.
[0034] like Figures 4 to 7 As shown, the lifting assembly includes a second leg 3, on which a base 31 is integrally formed. A first rotating column 311 is rotatably connected to the base 31, and a second rotating column 312 is rotatably connected to the first rotating column 311. A guide rail 22 is welded to the lower plate of the cargo box 2. The guide rail 22 has a guide groove 221 that matches the second rotating column 312. The second rotating column 312 is rotatably connected within the guide groove 221. The end of the second leg 3 away from the cargo box 2 passes through the lower panel of the loading box 1, and the second leg 3 is slidably connected to the loading box 1.
[0035] Specifically, after the low-altitude transport drone transports the goods to the destination, it begins to descend. When the second leg 3 touches the ground, the weight of the drone and the goods causes the second leg 3 to slide into the loading box 1. As the second leg 3 slides into the loading box 1, the first rotating column 311 rotates on the base 31, and the second rotating column 312 moves within the guide groove 221. This allows the cargo box 2 to be lifted by the lifting assembly, causing the cargo box 2 to rotate around the hinge column 21. The cargo box 2 tilts, and the goods on the cargo box 2 slide out of the cargo box 2 and eventually fall outside the loading box 1.
[0036] It is worth noting that due to outdoor transportation, the items inside cargo box 2 may get wet in rainy weather.
[0037] Furthermore, such as Figure 1 , Figure 2 and Figure 8 As shown, the loading box 1 is provided with a door 12, which is slidably connected to the loading box 1. The door 12 penetrates the upper panel of the loading box 1. A first bracket 13 is integrally formed on the door 12, which penetrates the loading box 1 and is slidably connected to the loading box 1.
[0038] Specifically, during the flight of the low-altitude transport drone, due to gravity, the door 12 seals the opening of the loading container 1, protecting the items inside. When the low-altitude transport drone lands, the first support 13 contacts the opposite side. Due to the gravity of the low-altitude transport drone and the items, the first support 13 slides into the loading container 1, and the door 12 also slides upward inside the loading container 1, allowing the loading container 1 to be opened.
[0039] It is worth noting that when the first support 13 and the second leg 3 touch the ground, the cargo box 2 will rotate. If the rotating cargo box 2 were to press against the door 12, it would cause the first support 13 and the second leg 3 to jam, preventing the unloading operation from being completed. Furthermore, there is a gap between the cargo box 2 and the door 12. When the first support 13 and the second leg 3 touch the ground, the cargo box 2 begins to rotate. Because of the gap between the cargo box 2 and the door 12, the wall of the cargo box 2 will not directly press against the door 12. When the cargo box 2 rotates to the position of the door 12, the height to which the door 12 rises avoids the wall of the cargo box 2, preventing jamming and ensuring the smooth completion of the unloading operation.
[0040] Preferably, there is also a gap between the wall of the container 2 and the inner wall of the loading box 1 to prevent friction between the container 2 and the loading box 1.
[0041] Furthermore, such as Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, a guide block 14 that matches the inner diameter of the cargo box 2 is integrally formed on the lower plate of the loading box 1. The guide block 14 has a second inclined surface 141 and a third inclined surface 142.
[0042] Specifically, as the storage box 2 gradually rotates, the left side wall of the storage box 2 and the third inclined surface 142 will fit together. At this time, the upper panel of the storage box 2 and the second inclined surface 141 opened on the guide block 14 are parallel, which ensures that the items slide from the storage box 2 onto the second inclined surface 141 and then fall to the ground under the guidance of the second inclined surface 141.
[0043] Furthermore, the door 12 has a first inclined surface 122 that matches the second inclined surface 141, and a pair of blocks 121 are integrally formed on the door 12. Specifically, during the flight of the low-altitude transport drone, the first inclined surface 122 adheres to the second inclined surface 141. Because the second inclined surface 141 is inclined upward from the opening of the loading box 1, rainwater will not flow upward even in heavy rain, ensuring the transport capability of the low-altitude transport drone in adverse weather conditions. The pair of blocks 121 also seal the gap between the guide block 14 and the loading box 1.
[0044] like Figure 1 , Figure 2 and Figure 5 As shown, a first foot 131 is integrally formed on the first support 13, and a second foot 32 is integrally formed on the second support leg 3. A first limiting plate 132 is integrally formed on the first support 13, and a second limiting plate 33 is integrally formed on the second support leg 3. The distance between the first limiting plate 132 and the lower end face of the loading box 1 is greater than the distance between the second limiting plate 33 and the lower end face of the loading box 1.
[0045] Specifically, after the low-altitude transport drone lands, the first support 13 and the second leg 3 slide upwards respectively. When the second limiting plate 33 contacts the lower panel of the loading box 1, the second leg 3 stops sliding upwards. At this time, the first support 13 continues to slide upwards until the first limiting plate 132 contacts the lower end surface of the loading box 1. At this point, the low-altitude transport drone tilts as a whole, which increases the tilt angle of the cargo box 2, making it easier for items on the cargo box 2 to slide off, and further ensuring the automatic unloading function of the low-altitude transport drone.
[0046] In addition, both the first foot 131 and the second foot 32 are circular. After contacting the ground, the second foot 32 can rotate around the ground to ensure the pressure of the first foot 131 on the ground, so that the first support 13 can slide upward.
[0047] When using, such as Figures 1 to 5 As shown, first, place the items into the cargo box 2. Before placing the items, operate the low-altitude transport drone to make the lower end of the loading box 1 land on the shelf, and then lift the first support 13 to open the loading box 1, so that the items can be placed into the cargo box 2.
[0048] When the low-altitude transport drone takes off, the first support 13 and the door 12 slide downwards due to gravity, and the door 12 lands on the guide block 14, sealing the loading box 1. After the low-altitude transport drone flies to its destination and descends, the first foot 131 and the second foot 32 contact the ground, the first support 13 and the second support leg 3 slide upwards, and the door 12 opens the loading box 1. At the same time, the cargo box 2 rotates around the hinge column 21, and the items on the cargo box 2 slide out, completing the unloading action.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
