[0024] The guide assembly 13 is used to guide the movement of the first mounting plate 6; Specifically, the guide assembly 13 includes two sleeves 14, which are symmetrically distributed about the center position of the fixing plate 8 and are respectively located at two ends of the fixing plate 8; Further, the sleeve 14 extends along the second direction, and the sleeve 14 has a first guide section, a second guide section and a third guide section which are sleeved in sequence, the first guide section has a second mounting end, and the end of the third guide section away from the fixing plate 8 is a fourth mounting end, the second mounting end is connected to the fixing plate 8, and the fourth mounting end is connected to the second mounting plate 7; Further, optionally, the diameter of the first guide segment is larger than the diameter of the second guide segment, which is larger than the diameter of the third guide segment; the second guide segment and the third guide segment are movably sleeved together, and the first guide segment and the second guide segment are movably sleeved together; Further, the sleeve 14 has a retracted state and an extended state; When the unlocking assembly 4 is in the first state, the fixing plate 8 and the first mounting plate 6 are close to each other, and the sleeve 14 is in a contracted state; when the unlocking assembly 4 is in the second state, the sleeve 14 is in an extended state.

[0025] The hook assembly includes a movable hook 15 and a fixed hook 16, which are used to lift the cargo 3; Specifically, a through hole is provided on the second mounting plate 7, and the fixing hook 16 is fixedly provided on the second mounting plate 7, and one end thereof away from the transport system passes through the through hole and extends to the side of the second mounting plate 7 away from the transport system; Furthermore, the movable hook 15 is movably arranged in the installation space, and one end thereof away from the transportation system passes through the through opening and extends to the side of the second installation plate 7 away from the transportation system; Optionally, there are two movable hooks 15 and two fixed hooks 16 respectively, which are arranged in pairs, and there are two lifting ears 23 on the cargo 3, which are matched with the two movable hooks 15 respectively; Furthermore, the hook assembly also includes a limit plate 17, which extends along the second direction and is movably arranged in the installation space. The two ends of the side wall of the limit plate 17 away from the fixed plate 8 are respectively connected to the two movable hooks 15, and a slider 18 is also arranged on the side wall of the limit plate 17 away from the fixed plate 8.

[0026] The second elastic component includes a second elastic member 19, and the second elastic member 19 is arranged in the installation space; Further, the second elastic member 19 has a fifth mounting end and a second free end, the fifth mounting end is connected to the second mounting plate, and one end of the second elastic member 19 close to the slider 18 is the second free end; optionally, the second elastic member 19 is a nitrogen spring, the second elastic member 19 is fixed in the mounting space, and extends along the first direction; Further, the second elastic component has a second compressed state and a second natural state; When the second elastic component is in the second compression state, the second elastic member 19 is compressed, the movable hook 15 and the fixed hook 16 are close to each other, and the ear 23 is hung on the movable hook 15; when the second elastic component is in the second natural state, the second elastic member 19 is extended, the movable hook 15 and the fixed hook 16 are separated, and the ear 23 is separated from the movable hook 15.

[0027] The limiting assembly includes a steel wire rope 20, and the fixing plate 8 has a third mounting portion 24 at the middle of the side wall away from the transportation system, and one end of the steel wire rope 20 is fixedly connected to the third mounting portion 24; Furthermore, the limiting assembly further includes a limiting pin 21, and one end of the steel wire rope 20 away from the fixing plate 8 is connected to the limiting pin 21; Furthermore, a limiting portion 22 adapted to the limiting pin 21 is provided on the side wall of the limiting plate 17 close to the transport system, and a through hole adapted to the limiting pin 21 is provided through the first mounting plate 6; When the second elastic component is in the second compression state, the second elastic member 19 is compressed, the movable hook 15 and the fixed hook 16 are close to each other, and the limit pin 21 extends through the through hole to the limit part 22 to limit the limit plate 17; when the second elastic component is in the second natural state, the limit pin 21 is separated from the limit part 22, and the second elastic member 19 is extended, pushing the slider 18 to move along the first direction, so that the limit plate 17 drives the movable hook 15 away from the fixed hook, and the ear 23 is separated from the movable hook 15, and the cargo 3 is dropped.

[0028] It should be noted that the length of the steel wire rope 20 is smaller than the length of the sleeve 14 in the extended state, so as to facilitate the stop pin 21 to be separated from the stop portion 22; It should be noted that, since the through hole is adapted to the limit pin 21, when the limit pin 21 and the limit plate 17 are limited, the limit pin 21 is not completely embedded in the limit portion 22, so the limit pin 21 can prevent the first mounting plate 6 and the limit plate 17 from moving relative to each other, thereby limiting the limit plate 17; It should be noted that, in actual application, the length of the sleeve 14 is adjustable so that the cargo 3 can reach a predetermined falling height.

[0029] Working principle: when the transport system is in the initial flight state, the unlocking assembly 4 is in the first state, the first section 10 and the second section 11 are an integrated structure, at this time, the fixed plate 8 and the first mounting plate 6 are close to each other, the first elastic assembly 5 is in the first compression state, the first elastic member 12 is compressed, the first free end abuts against the first mounting plate 6, the sleeve 14 is in a contracted state, the limit pin 21 is located in the limit portion 22, and the limit plate 17 is limited, the movable hook 15 and the fixed hook 16 are close to each other, the second elastic member 19 is compressed, and the ear 23 is hung on the movable hook 15; When the transportation system moves to the task window and the goods 3 need to be delivered, the unlocking member 9 receives the signal and changes from the first state to the second state. The first section 10 and the second section 11 are separated. Under the action of the first elastic member 12, the first mounting plate 6 is pushed away from the fixed plate 8 in the second direction. The sleeve 14 guides the movement of the first mounting plate 6. During the movement of the first mounting plate 6, since the length of the wire rope 20 is less than the length of the sleeve 14 in the extended state, before the sleeve 14 extends to the maximum length, the wire rope 20 will be straightened and pull the limit pin 21 out of the limit part 22, thereby releasing the limit on the limit plate 17. The second elastic member 19 pushes the slider 18 to move the limit plate 17 in the first direction, driving the movable hook 15 to move. When the moving distance of the movable hook 15 is greater than the thickness of the lifting ear 23, the lifting ear 23 is separated from the movable hook 15. At this point, the goods 3 can be delivered by unlocking once.

[0030] The above description is only a preferred embodiment of the present invention and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present invention is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
