[0002] Hotan region in Xinjiang is famous for its jade. The region is located at an altitude of about 0.5 kilometers and is characterized by high mountains, dangerous roads, and inconvenient transportation. Jade miners have to carry their luggage and food up the mountain each time. The weight they carry is small, and the jade they collect also has to be carried down the mountain. Because of the small amount of items they carry, they can only survive in the mining area for 3-5 days, which seriously affects the efficiency of jade mining. At the same time, the risk of people carrying heavy loads up the mountain is extremely high, and it is very easy to cause injury or death.

[0033] The following describes in further detail the features and performance of the flexible-wing UAV with folding function and the UAV airdrop system of this application, with reference to embodiments.
[0034] Example 1
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this application provides a drone airdrop system, which includes a flexible-wing drone with folding function and a payload pack 300 mounted on the flexible-wing drone with folding function. The flexible-wing drone with folding function includes a bottom frame 100, three rollers 110 rotatably connected to the bottom frame 100, a propeller 120 rotatably connected to the tail end of the bottom frame 100, an engine 130 for driving the propeller 120 to rotate, a fuel tank 140 connected to the engine 130, and a top frame 200 hinged to the top of the bottom frame 100. The payload 300 is fixed to the tail end of the bottom frame 100 via an engine mount. The tail end of the bottom frame 100 is also connected to the powered parachute 150 and a flight system for adjusting the attitude of the powered parachute 150. The top of the payload 300 is detachably connected to the top frame 200, which is configured to rotate toward or away from the bottom frame 100 to fold or unfold. The flight system includes a servo motor 280 and two control cables 290. One end of the two control cables 290 is connected to the powered parachute 150, and the other end of the two control cables 290 is connected to the servo motor 280.
[0036] The top frame 200 includes a front frame 210 with one end hinged to the front end of the bottom frame 100, a rear frame 220 with one end hinged to the rear end of the bottom frame 100, and a middle frame 230. The two ends of the middle frame 230 are respectively hinged to the ends of the front frame 210 and the rear frame 220 away from the bottom frame 100. The front frame 210 and the rear frame 220 can rotate simultaneously in a direction away from or towards each other, so that the middle frame 230 moves onto the bottom frame 100. Alternatively, the rear frame 220, middle frame 230, and front frame 210 may be stacked sequentially from bottom to top on the bottom frame 100; each side of the bottom frame 100 is connected to a first quick-release pin 240 that can move axially; when the rear frame 220 is rotated so that the middle frame 230 moves above the bottom frame 100, the two first quick-release pins 240 move axially to insert or remove from the rear frame 220 to lock or unlock the rear frame 220 and the bottom frame 100.
[0037] A rotatable roller 110 is connected to the front end of the bottom frame 100. A wheel axle 160 is inserted into each side of the rear end of the bottom frame 100, and each wheel axle 160 is connected to a rotatable roller 110. The bottom frame 100 is connected to two second quick-release pins 250, each corresponding to a wheel axle 160. The second quick-release pins 250 can move axially to insert into or release from the corresponding wheel axle 160 to lock or unlock the wheel axle 160 and the bottom frame 100. The bottom of the bottom frame 100 has four limiting posts 170 located outside the payload 300 to define its position. The bottom frame 100 is connected to an arc-shaped propeller guard frame 180 located on the outer side of the top of the propeller 120.
[0038] The middle frame 230 is provided with a hook 260 that can be opened and closed to release or hang the load bag 300. The hook 260 includes a hook seat 231 connected to the middle frame 230, an arc-shaped fixed buckle 232 connected to the hook seat 231, and an arc-shaped movable buckle 233 rotatably connected to the hook seat 231. When the movable buckle 233 rotates, it cooperates with the fixed buckle 232 to close to form a ring or open the ring.
[0039] The UAV airdrop system provided in this embodiment involves placing a foldable flexible-wing UAV, consisting of a bottom frame 100 and a top frame 200, on a flat surface. The powered parachute 150 is then placed on the bottom surface of the rear end of the bottom frame 100 and unfolded. After aligning the central axis of the powered parachute 150 with the engine shaft of the engine 130, the powered parachute 150 is unfolded as flat as possible to both sides of the bottom frame 100. The parachute lines on both sides of the powered parachute 150 are then attached and secured to the open hooks on both sides of the arc-shaped propeller guard frame 180 located on the outer side of the top of the propeller 120, which is connected to the bottom frame 100. In weather conditions with wind speeds of level 3 or below, the system should be placed facing the wind, i.e., the powered parachute 150 should be placed downwind. Note that the parachute lines on both sides of the powered parachute 150 should be layered and not tangled. The front frame 210 and the rear frame... The frame 220 rotates simultaneously in directions away from each other, so that the rear frame 220, the middle frame 230 and the front frame 210 are stacked sequentially from bottom to top on the bottom frame 100. The rear frame 220 and the front frame 210 are rotated until they are vertically arranged and the middle frame 230 is moved to be parallel above the bottom frame 100. At this time, the two first quick-release pins 240 are moved axially and inserted into both sides of the rear frame 220 to lock the positions of the rear frame 220 and the bottom frame 100. At this time, the load pack 300 can be placed under the middle frame 230 and the top of the load pack 300 is hung on the hook 260. That is, the movable buckle 233 is rotated to open the ring buckle in the direction away from the fixed buckle 232. After the top opening of the load pack 300 is put on the fixed buckle 232, the movable buckle 233 is rotated to close the ring buckle in the direction closer to the fixed buckle 232.
[0040] When activating the drone airdrop system, the remote controller starts the engine 130, which rotates the propeller 120. The propeller 120 slowly accelerates until the powered paraglider 150 rises directly above the bottom frame 100 and top frame 200. Then, the throttle of the engine 130 is rapidly increased to propel the drone airdrop system into flight. The remote controller controls the servo motor 280 to rotate in both directions, which in turn pulls the two control cables 290 to adjust the left and right sides of the powered paraglider 150, thus adjusting its flight direction.
[0041] Once the drone airdrop system reaches its designated destination and lands on the ground, the movable buckle 233 can be rotated away from the fixed buckle 232 to open the buckle. The payload pack 300 can then be removed, supplies taken out, and the materials to be transported can be put back into the payload pack 300 and hung on the hook 260. The drone airdrop system can then be used to transport the payload pack 300 back.
[0042] After the drone airdrop system provided in this application embodiment is used up, the two rollers 110 at the tail end of the bottom frame 100 can be quickly disassembled. During disassembly, the two second quick-release pins 250 are moved axially to disengage from the corresponding axles 160, thereby unlocking the axles 160 and the bottom frame 100. Then, the two axles 160 are pulled out from both sides of the bottom frame 100 to complete the disassembly of the two rollers 110 at the tail end of the bottom frame 100.
[0043] The bottom frame 100 has four limiting posts 170 located on the outside of the payload pack 300 to limit its position. When the top of the payload pack 300 is hung on the hook 260, the four buckles at the bottom of the payload pack 300 can be respectively fitted onto the four limiting posts 170 on the bottom frame 100 for fixed positioning. The bottom frame 100 is connected to an arc-shaped propeller protection frame 180 located on the outside of the top of the propeller 120. The propeller protection frame 180 can be used to cover and protect the propeller 120, preventing the powered paraglider 150 and parachute lines from being wound into the rotating propeller 120 and affecting flight.
[0044] In other alternative embodiments, the number of rollers 110 connected to the bottom frame 100 may be four or more.
[0045] Example 2
[0046] like Figure 7 As shown, this application provides a drone airdrop system, which has a structure that is roughly the same as the drone airdrop system provided in embodiment 1. The difference is that in this embodiment, the top frame 200 is provided with a drive mechanism for driving the hook 260 to open and close. The drive mechanism is a drive motor 270. The output shaft of the drive motor 270 is connected to the movable buckle 233 to drive the movable buckle 233 to rotate and cooperate with the fixed buckle 232 to open and close the ring buckle.
[0047] The drone airdrop system provided in this application embodiment uses a drive motor 270 to drive the movable buckle 233 to rotate and cooperate with the fixed buckle 232 to open and close the ring buckle, which can realize automatic airdrop operation. When the drone airdrop system flies to the set destination and needs to be airdropped, the drive motor 270 can be controlled to drive the movable buckle 233 to rotate, so that the movable buckle 233 rotates away from the fixed buckle 232 to open the ring buckle, so that the payload pack 300 falls due to gravity and lands at the destination.

The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
