Under normal circumstances, the lifting plate 242 is arranged in the lifting slot 24 along the vertical direction, and the rotating direction of the lifting plate 242 is from the lifting slot 24 to the mounting slot 22.

[0043] Specifically, the connecting seat 3 is located at the lower end of the mounting seat 2, and the connecting seat 3 is used to connect the mounting object 4 to mount the mounting object 4 on the mounting seat 2 through the connecting seat 3. The connecting seat 3 comprises a connecting plate 31, two alignment frames 32 symmetrically arranged on both sides of the connecting plate 31, a mounting mechanism 33 mounted between the two alignment frames 32, and a connecting piece 34. The mounting mechanism 33 is fixedly mounted at the middle part of the connecting plate 31. The two alignment frames 32 on both sides are matched with the abutting top cavity 213 of the abutting groove 21, wherein the top end of the alignment frame 32 is provided with a rotating rotating wheel to slide into the abutting top cavity 213 along the first abutting wall 211 or the second abutting wall 212 through the rotating wheel at the top end of the alignment frame 32. The mounting mechanism 33 comprises a fixed rod 331 arranged at the bottom end, which is fixedly mounted at the middle part of the connecting plate 31. The middle part of the fixed rod 331 is provided with a shaft 332, and the outer periphery of the shaft 332 is sleeved with a sleeve 333 fixedly connected with the fixed rod 331. The upper end of the sleeve 333 is sleeved with a sliding mounting block 334, and the sliding mounting block 334 is in sliding connection with the shaft 332. The upper end of the sliding mounting block 334 is provided with a magnet ring 334-1 fixedly connected with the sliding mounting block 334. Under normal circumstances, the sliding mounting block 334 abuts against the upper end of the sleeve 333. The upper end of the shaft 332 is fixedly provided with a fixed mounting block 335, and the lower end of the fixed mounting block 335 is provided with a limiting magnetic groove 335-1, wherein the limiting magnetic groove 335-1 and the magnet ring 334-1 are matched with each other, and when the magnet ring 334-1 abuts into the limiting magnetic groove 335-1, the sliding mounting block 334 and the fixed mounting block 335 are tightly abutted. Under normal circumstances, there is a gap between the fixed mounting block 335 and the sliding mounting block 334, which is the sliding distance of the sliding mounting block 334 on the shaft 332. It should be noted that the sliding mounting block 334 and the fixed mounting block 335 are in the shape of a circular truncated cone, and the two sliding mounting blocks 334 and the fixed mounting block 335 are oppositely arranged, and the long edges of the two mounting blocks are oppositely arranged. The inclination angle of the outer slope surface of the sliding mounting block 334 and the fixed mounting block 335 matches with the inclination angle of the inner slope surface of the abutting block 234. The connecting piece 34 is fixedly arranged at the lower end of the connecting plate 31, and a through hole is formed in the middle part of the connecting piece 34 to fix the mounting object 4 to the connecting piece 34 through a fixing bolt.

[0044] When the mounting object 4 needs to be mounted, the mounting object 4 is fixedly connected with the connecting piece 34 and moves towards the mounting seat 2 through the connecting seat 3 to move and position towards the positioning slot 21 through the positioning frame 32. After successful positioning, the mounting mechanism 33 is inserted into the mounting slot 22, and the outer periphery of the fixed mounting block 335 is pressed against the block 234 and moves along the inner side wall of the block 234, so that the block 234 is extruded. After being extruded, the fixed mounting block 335 forms a path between the two blocks 234 until the upper end of the block 234, the lower end of the fixed mounting block 335 is at the upper end of the block 234, and the block 234 is no longer extruded at this time to restore the original path and support the lower end of the fixed mounting block 335 to realize mounting of the mounting object 4 in the mounting slot 22. When the mounting object 4 needs to be released, the driving device 243 is driven to rotate the rotating shaft 241 to control the lifting plate 242 to move the sliding mounting block 334 towards the fixed mounting block 335. The sliding mounting block 334 moves towards the fixed mounting block 335, the outer periphery of the upper end of the sliding mounting block 334 again pushes away the block 234, and the magnet ring 334-1 moves towards the limiting magnetic groove 335-1 to realize mutual attraction between the magnet ring 334-1 and the limiting magnetic groove 335-1. At this time, the magnet ring 334-1 and the limiting magnetic groove 335-1 that are attracted to each other fix the sliding mounting block 334 and the fixed mounting block 335, the distance between the sliding mounting block 334 and the fixed mounting block 335 disappears, the path between the two blocks 234 matches the maximum outer diameter of the two mounting blocks, so that the two mutually pressed mounting blocks slide out of the mounting slot 22 along the path between the two blocks 234 to be released.

[0045] Working principle:

[0046] When mounting, the connecting seat 3 is rolled and guided along the positioning slot 21 of the mounting seat 2 through the positioning frames 32 on both sides, so that the mounting mechanism 33 is inserted into the mounting slot 22, the fixed mounting block 335 and the sliding mounting block 334 push away the blocks 234 of the pressing mechanism 23 and enter the mounting position, and are clamped by the blocks 234; when releasing, the driving device 243 drives the lifting plate 242 to rotate upwards, pushes the sliding mounting block 334 upwards, and makes the sliding mounting block 334 and the fixed mounting block 335 attract and merge through the magnet ring 334-1 and the limiting magnetic groove 335-1 of the fixed mounting block 335, so that the overall outer diameter is reduced, and the sliding mounting block 334 is released from the blocks 234, thereby realizing quick release.

[0047] Embodiment 2:

[0048] Please refer to Figures 18-19 An emergency mounting mechanism for an unmanned helicopter, which is different from embodiment 1 and further comprises a parking platform 5 for parking the body 1.

[0049] Specifically, the middle part of the parking platform 5 is provided with a parking part 51 for supporting the body 1 to land. One side of the parking part 51 is provided with an emergency storage box 52, the output port of the emergency storage box 52 is connected with a conveying mechanism 53, one end of the conveying mechanism 53 communicates with the emergency storage box 52, and the other end of the conveying mechanism 53 is located at the lower end of the parking part 51. Wherein, the conveying mechanism 53 is provided with a conveying belt which is along the emergency storage box 52 towards the lower part of the parking part 51, to convey the hanging load 4. The middle part of the parking part 51 is provided with a hanging lifting plate 54 with lifting function, and the hanging lifting plate 54 is lowered to the lowest end and is flush with the conveying belt of the conveying mechanism 53, to facilitate the hanging load 4 to be conveyed on the hanging lifting plate 54. When the hanging lifting plate 54 rises, the alignment and hanging of the connecting seat 3 and the hanging mounting seat 2 at the lower end of the body 1 are realized.

[0050] Working principle:

[0051] After the unmanned helicopter lands on the parking part 51 of the parking platform 5, the conveying mechanism 53 conveys the spare hanging load 4 in the emergency storage box 52 to the hanging lifting plate 54, the hanging lifting plate 54 rises, pushes the hanging load 4 and its connecting seat 3 to be connected with the hanging mounting seat 2 at the lower end of the body 1, and the automatic hanging and replenishment are completed.
