[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0018] Please see Figures 1 to 5 The present invention provides a loading and unloading device for a logistics drone, comprising a fuselage 1, a landing gear 2, a lifting wing assembly 3, a fixing component 4, and an auxiliary component 5. Multiple landing gears 2 are symmetrically arranged below the fuselage 1, and multiple elevator wing assemblies 3 are respectively installed on both sides of the fuselage 1. Each elevator wing assembly 3 has two elevator wings, and the two elevator wings are spaced apart along the length of the fuselage 1. The elevator wings on the left and right sides are symmetrically arranged. The fixing component 4 is installed at the bottom of the fuselage 1.
[0019] Two of the landing gear components serve a supporting function, providing a stable support point for the drone's landing. At the same time, the fuselage 1 supplies power to multiple elevator wing assemblies 3, enabling the elevator wing assemblies 3 to drive the fuselage 1 to take off and land; Furthermore, when the drone needs to carry cargo, the cargo box needs to be placed manually on the fixing component 4, and then fixed by the fixing component 4 according to the size of the cargo box. After the fixing is completed, the power in the fixing component 4 is turned on to attach the cargo box to the bottom of the drone body 1. Then, the low wind resistance mode of the auxiliary component 5 is canceled manually (that is, the auxiliary component 5 is removed from the bottom of the drone body 1), and adjusted according to the size of the cargo box. After adjusting to the appropriate size, the auxiliary fixing of the cargo box is completed. At this time, the drone can take off. Furthermore, once the drone reaches the designated location, the auxiliary component 5 is manually adjusted and its distance is readjusted so that it can be re-fixed under the fuselage 1 (i.e., the low-drag mode is restored). Then, the fixing component 4 is powered off, so that the cargo is completely disconnected from the fuselage 1, thereby achieving the purpose of retrieving the cargo, and the drone can then return to base.
[0020] In this embodiment, the built-in power supply 41 is installed at the bottom of the body 1. Multiple springs 42 are evenly distributed along the bottom of the body 1, with one end of each spring 42 connected to the bottom of the body 1 and the other end connected to the top of the connecting plate 43. Multiple central circuit boards 44 are evenly distributed along the bottom of the connecting plate 43. Multiple electromagnets 45 correspond one-to-one with the multiple central circuit boards 44, and are installed at the bottom of the central circuit boards 44 and electrically connected to the built-in power supply 41. Multiple pulse valves 46 correspond one-to-one with the central circuit boards 44, and are inserted through the central circuit boards 44 and electrically connected to the built-in power supply 41. Multiple fixing parts 47 are provided, and the multiple fixing parts 47 are connected to the electromagnets 42. 5. A one-to-one correspondence is established, and the fixing part 47 is installed at the bottom end of the electromagnet 45. Each magnet group 471 has two magnets, and the two magnets correspond one-to-one with two oppositely arranged electromagnets 45. The magnets are installed at the bottom end of the electromagnet 45. A plurality of belts 472 correspond one-to-one with a plurality of magnet groups 471. The belts 472 are installed at the bottom end of the magnet groups 471. A plurality of adjusting buckles 473 correspond one-to-one with a plurality of belts 472, and the adjusting buckles 473 are slidably disposed on the belts 472. A plurality of mounting rods 474 correspond one-to-one with a plurality of adjusting buckles 473, and the mounting rods 474 are installed on the adjusting buckles 473. A plurality of pulse air valves 46 correspond one-to-one with the magnets in the plurality of magnet groups 471, and the output end of the pulse air valve 46 faces the magnet.
[0021] The belt 472 is provided with an adjustment buckle 473 at one end, which is the adjustment end, and the belt 472 is not provided with the adjustment buckle 473 at the other end. The adjustment buckle 473 is provided with an installation rod 474. The belt 472 is wrapped around the installation rod 474 to achieve fixation. The adjustment buckle 473 is provided with three openings. The opening without the installation rod 474 is the first opening. The opening separated by the installation rod 474 and adjacent to the first opening is the second opening. The opening adjacent to the second opening is the third buckle. Meanwhile, according to the size of the cargo box, adjust the distance the belt 472 is pulled out in the adjusting buckle 473. First, one of the belts 472 is used manually to fix the length of the cargo box. At this time, the adjusting end and the end of the belt 472 start from the top of the cargo box and wrap along the length of the cargo box, and meet at the bottom of the cargo box. Then, the end is inserted into the first opening, and the amount of insertion is adjusted according to the length of the cargo box. It is then extended from the bottom of the second opening and finally inserted into the third opening. At this time, the end is fastened at the adjusting buckle 473 to form a fixing buckle, thereby achieving the purpose of fixing. The fixing of the belt 472 in the width direction is the same as the above principle. Conversely, when the cargo box reaches the designated position and the goods need to be unloaded, the belt 472 is pulled out in the reverse order of insertion into the opening. Furthermore, after the cargo box is fixed by the fixing part 47, the built-in power supply 41 is powered on and starts to work. The built-in power supply 41 sends power to the internal parts of multiple central circuit boards 44, and then the central circuit boards 44 supply power to multiple electromagnets 45. At this time, the electromagnets 45 can attract the magnet on the belt 472, so that the cargo box is connected to the bottom of the body 1, thereby achieving the purpose of the drone carrying the cargo box. When the drone arrives at the delivery position, the central circuit board 44 stops supplying power to the electromagnets 45, and instead supplies power to the pulse air valve 46, so that the pulse air valve 46 sprays airflow towards the magnet, thereby quickly separating the electromagnets 45 from the magnet. Then the belt 472 on the cargo box can be removed to complete the unloading work.
[0022] In this embodiment, the auxiliary mounting bracket 51 is installed at the bottom end of the elevator wing, the rotating bracket 52 is rotatably mounted on the auxiliary mounting bracket 51, the electric push rod 53 is installed at the bottom end of the rotating bracket 52, the threaded adjusting rod 54 is rotatably mounted at the output end of the electric push rod 53, the auxiliary support part 55 is rotatably mounted at the output end of the threaded adjusting rod 54, and multiple storage racks 56 are installed at the bottom end of the fuselage 1, respectively located at the four corners of the bottom end of the fuselage 1. The auxiliary plate 551... Installed at the output end of the threaded adjusting rod 54, the rotating bearing 552 is rotatably disposed at one end of the auxiliary plate 551, the rotating plate 553 is installed at one end of the rotating bearing 552, the adjusting gear 554 is rotatably disposed on the rotating plate 553, a plurality of adjusting chains 555 mesh with the adjusting gear 554, a plurality of clamping arms 556 correspond one-to-one with the plurality of adjusting chains 555, and the clamping arms 556 are installed on the adjusting chains 555, and the clamping arms 556 are made of rubber.
[0023] Among them, the electric push rod 53 has a built-in power supply; Meanwhile, after the cargo box is connected to the bottom of the machine body 1 via the fixing part 47, the rotating frame 52 needs to be manually adjusted to separate the auxiliary support part 55 from the storage rack 56. Then, the rotating frame 52 is placed in a vertical position, and the electric push rod 53 is extended by the external controller according to the size of the cargo box. When the electric push rod 53 pushes the threaded adjustment rod 54 to the expected position, the threaded adjustment rod 54 is manually rotated to bring the auxiliary support part 55 closer to the cargo box. At this time, the rotating plate 553 is manually adjusted. The rotating plate 553 rotates on the auxiliary plate 551 through the rotating bearing 552. Then, the clamping arm 556 is made parallel to the outer wall of the cargo box. Then, the adjusting gear 554 is manually rotated to make the adjusting chain 555 meshing with the adjusting gear 554 move relative to each other. The clamping arm 556 on the adjusting chain 555 also moves accordingly. When the clamping arm 556 is completely in contact with the cargo box, the adjusting gear 554 is stopped, thereby achieving the purpose of auxiliary fixation. Furthermore, after the cargo box reaches the designated position and the unloading is completed, the adjusting gear 554 is manually rotated in the opposite direction to cause the adjusting chain 555 to drive the clamping arm 556 to move in opposite directions, thereby canceling the auxiliary clamping work on the cargo box. Subsequently, the threaded adjusting rod 54 is manually rotated in the opposite direction to restore the auxiliary support part 55 to its initial position. Then, the rotating frame 52 is manually adjusted to rotate towards the storage rack 56. When the rotating frame 52 drives the auxiliary support part 55 to the position of the storage rack 56, the adjusting gear 554 is manually rotated again. The working principle is the same as the above-mentioned cargo box clamping principle, so that the clamping arms 556 on the two chains are in contact with the storage rack 56, thereby preventing the auxiliary support part 55 from slipping off by itself. This reduces the wind resistance and power consumption of the drone during the return trip.
[0024] In summary, this loading and unloading device for a logistics drone includes a fuselage 1, multiple landing gears 2, multiple elevator wing assemblies 3, a fixing component 4 for securing cargo, and an auxiliary component 5 for assisting in securing cargo according to its size. This invention avoids the problem of insufficient space in traditional cargo boxes by using the adjusting belt 472 and adjusting buckle 473 in the fixing component 4, thereby increasing the drone's transport capacity. The electromagnet 45 and magnet assembly 471 in the fixing component 4 avoid the drawback of traditional drone hook-lock structures easily damaging the surface of the cargo box, thus improving the integrity of transported goods. Furthermore, the pulse air valve 46 allows for faster unloading, reducing manual labor intensity. The adjusting gear 554, adjusting chain 555, and clamping arm 556 in the auxiliary support 55 can accommodate larger cargo boxes, while avoiding the risk of slippage associated with a single fixing structure. Finally, the storage rack 56 keeps the auxiliary support 55 in a retracted state when not in use, thereby reducing wind resistance during drone flight.
