[0041] The first elastic assembly 5 includes two first elastic members 12.

[0045] The guiding component 13 is used to guide the movement of the first mounting plate 6;

[0046] Specifically, the guiding component 13 includes two sleeves 14, which are symmetrically distributed about the central position of the fixing plate 8 and are respectively located at both ends of the fixing plate 8;

[0047] Furthermore, the sleeve 14 extends along the second direction. The sleeve 14 has a first guiding section, a second guiding section, and a third guiding section that are sleeved in sequence.

The second guiding section and the third guiding section are movably sleeved, and the first guiding section and the second guiding section are movably sleeved;

[0049] Furthermore, the sleeve 14 has a contracted state and an extended state;

[0050] When the unlocking component 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 the contracted state; when the unlocking component 4 is in the second state, the sleeve 14 is in the extended state.

[0051] The hook component includes a movable hook 15 and a fixed hook 16, which are used to lift the goods 3;

[0052] Specifically, a through hole is provided through the second mounting plate 7. The fixed hook 16 is fixedly arranged on the second mounting plate 7, and one end thereof far from the transportation system penetrates through the through hole and extends to the side of the second mounting plate 7 far from the transportation system;

[0053] Furthermore, the movable hook 15 is movably arranged in the installation space, and one end thereof far from the transportation system penetrates through the through hole and extends to the side of the second mounting plate 7 far from the transportation system;

[0054] Optionally, there are two movable hooks 15 and two fixed hooks 16 respectively, and they are arranged in pairs. There are two lifting lugs 23 on the goods 3, which are respectively matched with the two movable hooks 15;

[0055] Furthermore, the hook component further includes a limiting plate 17. The limiting plate 17 extends along the second direction and is movably arranged in the installation space. Both ends of the side wall of the limiting plate 17 far from the fixing plate 8 are respectively connected to the two movable hooks 15, and a sliding block 18 is also arranged on the side wall of the limiting plate 17 far from the fixing plate 8.

[0056] The second elastic component includes a second elastic member 19, and the second elastic member 19 is arranged in the installation space;

[0057] 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 the 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, and the second elastic member 19 is fixed in the installation space and extends along the first direction;

[0058] Further, the second elastic component has a second compressed state and a second natural state;

[0059] When the second elastic component is in the second compressed state, the second elastic member 19 is compressed, the movable hook 15 and the fixed hook 16 approach each other, and the lug 23 is hung on the movable hook 15; when the second elastic component is in the second natural state, the second elastic member 19 extends, the movable hook 15 and the fixed hook 16 are separated, and the lug 23 disengages from the movable hook 15.

[0060] The limiting component includes a steel wire rope 20. The middle part of the side wall of the fixing plate 8 away from the transportation system has a third mounting portion 24, and one end of the steel wire rope 20 is fixedly connected to the third mounting portion 24;

[0061] Further, the limiting component further includes a limiting pin 21, and the end of the steel wire rope 20 away from the fixing plate 8 is connected to the limiting pin 21;

[0062] Further, a limiting portion 22 adapted to the limiting pin 21 is provided on the side wall of the limiting plate 17 close to the transportation system, and the first mounting plate 6 is provided with a through hole adapted to the limiting pin 21 corresponding to the penetration of the limiting pin 21;

[0063] When the second elastic component is in the second compressed state, the second elastic member 19 is compressed, the movable hook 15 and the fixed hook 16 approach each other, the limiting pin 21 penetrates through the through hole and extends into the limiting portion 22 to limit the limiting plate 17; when the second elastic component is in the second natural state, the limiting pin 21 disengages from the limiting portion 22, the second elastic member 19 extends, pushes the slider 18 to move along the first direction, so that the limiting plate 17 drives the movable hook 15 away from the fixed hook, and the lug 23 disengages from the movable hook 15, and the goods 3 are dropped.

[0064] It should be noted that the length of the steel wire rope 20 is less than the length of the sleeve 14 in the extended state, which is convenient for the limiting pin 21 to disengage from the limiting portion 22;

[0065] It should be noted that since the through hole is adapted to the limiting pin 21, when the limiting pin 21 is limited by the limiting plate 17, the limiting pin 21 is not completely embedded in the limiting portion 22. Therefore, the limiting pin 21 can prevent the relative movement between the first mounting plate 6 and the limiting plate 17, thereby limiting the limiting plate 17;

[0066] It should be noted that in practical applications, the length of the sleeve 14 is adjustable to enable the cargo 3 to reach a predetermined falling height.

[0067] Working principle: When the transportation system is in the initial flight state, the unlocking component 4 is in the first state, and the first section 10 and the second section 11 are of an integral structure. At this time, the fixing plate 8 and the first mounting plate 6 are close to each other, the first elastic component 5 is in the first compressed 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 within the limiting portion 22 to limit the limiting plate 17, the movable hook 15 and the fixed hook 16 are close to each other, the second elastic member 19 is compressed, and the lug 23 is hung on the movable hook 15.

[0068] When the transportation system moves to the mission window and the cargo 3 needs to be dropped, the unlocking member 9 receives a 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 to move away from the fixing plate 8 along 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 steel wire rope 20 is less than the length of the sleeve 14 in the extended state, before the sleeve 14 extends to its maximum length, the steel wire rope 20 will be straightened and pull the limit pin 21 out of the limiting portion 22, releasing the limit on the limiting plate 17. The second elastic member 19 pushes the slider 18, causing the limiting plate 17 to move along 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 lug 23, the lug 23 disengages from the movable hook 15, thus realizing the dropping of the cargo 3 through a single unlocking.

[0069] The above description is only the preferred embodiment of the present invention and an explanation of the applied technical principles. 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 the specific combination of the above technical features, and 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. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the present invention.
