[0066] Please refer to Figure 3 In this embodiment, the airdrop system 010 includes a transmission system 300; the transmission system 300 includes a side guide rail 310 and a roller platform 320.

[0067] Specifically, the two side guide rails 310 are symmetrically arranged along the first side baffle 210 and the second side baffle 220 respectively; four roller platforms 320 arranged in parallel are arranged between the two side guide rails 310; the four roller platforms 320 cooperate with the two side guide rails 310 to transport goods.

[0068] Among them, a plurality of bearing rollers 330 are arranged on the roller platform 320, and the goods are carried by the roller platform 320, which has a strong carrying capacity and a small movement resistance.

[0069] Among them, a fixed limit lock 350 is arranged at the end of the transmission system 300 to prevent the goods from derailing; and a third cargo limit lock 340 is arranged between multiple cargo positions.

[0070] It is worth mentioning that the second cargo limit lock 250, the first cargo limit lock 240 and the third cargo limit lock 340 in this embodiment can be transverse limit locks. The transverse limit lock adopts a linkage mechanism position lock and includes a motor, a stopper, a support arm, a base and a position sensor; when the transverse limit lock is working, the motor pushes the support arm to raise and lower the stopper, thereby realizing the limit or no limit of the cargo.

[0071] The transport system 300 is equipped with cargo sensors corresponding to a plurality of cargo positions, and the cargo sensors are used to detect whether there are cargoes on the cargo positions of the transport system 300 .

[0072] Please refer to Figure 4 In this embodiment, the airdrop system 010 includes a drive system 400 , and the drive system 400 includes a slide rail 410 , a drive structure 430 and a drive arm 420 .

[0073] Specifically, multiple driving arms 420 are slidably connected to the slide rail 410, the slide rail 410 is set on the top of the delivery compartment, and the driving structure 430 is installed on the driving arm 420 and is used to drive the goods to move between multiple cargo positions and to drive the goods to move between the cargo positions and the delivery position 013.

[0075] Among them, the driving arm 420 is a plate-like structure, the first end of the driving arm 420 is slidably connected to the slide rail 410, and is also connected to the driving structure 430 at the first end; the second end of the driving arm 420 acts on the lower part of the center of gravity of the cargo when driving the cargo, facilitating the movement of the cargo.

[0076] Among them, the driving structure 430 includes a second motor 432 and a gear 431 that is transmission-connected to the output end of the second motor 432; one end of the driving device is installed on the first end of the driving arm 420, and the other end is transmission-connected to the transmission rack 440 on the slide rail 410 through the gear 431.

[0077] Understandably, please refer to Figure 5 , the second motor 432 of the driving structure 430 drives the driving arm 420 to move on the two slide rails 410 by driving the gear 431, so that the driving arm 420 drives the goods. And when the goods are driven, the driving arms 420 in front and behind the goods can guide the goods and prevent the goods from tipping over; when the goods are at the placement position 013, the goods at the placement position 013 can be limited by the front and rear guide arms and the first side baffle 210 and the second side baffle 220, which guides the goods at the placement position 013, guides the goods when placing them, and ensures the placement posture of the goods.

[0078] Please refer to Figure 1-Figure 3 In this embodiment, the airdrop system 010 includes a loading platform 500 .

Depending on the usage, the loading platform 500 can be used for unloading or loading cargo.

[0080] The loading platform 500 is a ball platform, and a plurality of loading balls 510 are arranged on the platform, which can reduce the movement resistance during the loading and delivery of goods.

[0081] In this embodiment, the airdrop system 010 also includes a plurality of parachute opening ropes.

[0082] Specifically, one end of the plurality of parachute opening ropes is respectively connected to the driving structure 430 of the driving system 400 or is slidably connected to the slide rail 410 of the driving system 400, and the other end is used to connect to the parachute opener on the cargo.

[0083] It is understandable that during the delivery of the cargo, the tethered parachute pull rope will trigger the cargo's parachute opener, so that after the cargo arrives at the specified time, the delivery parachute in the parachute opener will open, and the cargo can land with the parachute.

[0084] Please refer to Figure 6 In this embodiment, the airdrop system 010 is loaded with three goods as an example. Therefore, two cargo positions are correspondingly set on the transmission system 300; the cargo positions on the transmission system 300 are the first cargo position 011 and the second cargo position 012, and the cargo position on the loading platform 500 is the third cargo position 014. The first cargo position 011 is adjacent to the second cargo position 012; one end of the delivery position 013 is connected to the second cargo position 012, and the other end is connected to the third cargo position 014.

[0085] For details, please refer to Figure 3 , a fixed limit lock 350 is set at one end of the first cargo position 011; a third cargo limit lock 340 is set between the first cargo position 011 and the second cargo position 012. A second cargo limit lock 250 is set between the second cargo position 012 and the delivery position 013; a first cargo limit lock 240 is set between the delivery position 013 and the third cargo position 014.
