[0029] Refer to Figures 1 to 4 , Figure 1 is a perspective view of the delivery cloud platform of the first embodiment, Figure 2 is Figure 1 the cross-sectional view of the delivery cloud platform in Figure 3 is Figure 1 the perspective view of the interior of the delivery cloud platform in Figure 4 is Figure 1An oblique view of another angle inside the dropping cloud platform. The dropping cloud platform of this embodiment includes a cloud platform body 100, a wire winding device 200, a hook 300 and a wire cutting device 400. The wire winding device 200 includes a first driving device 210, a wire winding wheel 220, a cycloid shaft 230, a pulley assembly 240 and a lifting rope 250. One end of the lifting rope 250 is fixed on the wire winding wheel 220, and the other end of the lifting rope 250 is fixed to the hook 300. Driven by the first driving device 210, the wire winding wheel 220 rotates forward, and the lifting rope 250 is wound around the wire winding wheel 220, and the hook 300 continuously approaches the cloud platform body 100, so as to retract the item hung on the hook 300; or, driven by the first driving device 210, the wire winding wheel 220 rotates reversely, and the lifting rope 250 is released from the wire winding wheel 220, and the hook 300 continuously moves away from the cloud platform body 100, so as to lower the item hung on the hook 300, so as to remove the item from the hook 300. The wire cutting device 400 can cut the lifting rope 250, so that when the lifting rope 250 is hung on a tree branch or an electric wire, the unmanned aerial vehicle can be separated in time to avoid greater losses.

[0030] Specifically, the first driving device 210 includes a motor 211, a worm 212 and a worm gear 213. The rotating shaft of the motor 211 is matched with the worm 212 through a gear set, so that the worm 212 can rotate. The worm 212 and the worm gear 213 are engaged, and the worm gear 213 is fixedly connected to the wire winding wheel 220, so that the wire winding wheel 220 rotates forward or reversely. At the same time, the speed of the motor 211 is reduced to the wire winding wheel 220. To prevent the lifting rope 250 from detaching from the wire winding wheel 220 under the action of the gravity of the item hung on the hook 300, the worm 212 and the worm gear 213 can be self-locked, that is, the helix angle of the worm 212 is less than the friction angle of the contact between the worm 212 and the worm gear 213.

[0031] In another embodiment, the motor 211 can also directly drive the wire winding wheel 220 after deceleration by a gear set. At this time, the gear set needs to have a large reduction ratio and will occupy a relatively large space.

[0032] To enable the suspension rope 250 to be evenly wound around the winding wheel 220, a cycloidal shaft 230 is provided. The cycloidal shaft 230 is rotatably connected to the pan-tilt body 100 (achieved through a bearing). Moreover, one end of the cycloidal shaft 230 is connected to the winding wheel 220 through an additional gear set to achieve synchronous rotation (synchronous rotation means that when the winding wheel 220 rotates, the cycloidal shaft 230 rotates; when the winding wheel 220 stops rotating, the cycloidal shaft 230 also stops rotating). A spiral reciprocating groove is provided on the surface of the cycloidal shaft 230. The spiral reciprocating groove includes a first spiral groove 231 and a second spiral groove 232. The spiral direction of the first spiral groove 231 is opposite to that of the second spiral groove 232, and the lead of the first spiral groove 231 is equal to the lead of the second spiral groove 232. The end of the first spiral groove 231 is connected to the starting end of the second spiral groove 232, and the end of the second spiral groove 232 is connected to the starting end of the first spiral groove 231. After the suspension rope 250 is led out from the winding wheel 220, it passes through the spiral reciprocating groove and then is fixedly connected to the hook 300. When the winding wheel 220 rotates to take up the line, under the action of the spiral reciprocating groove, the suspension rope 250 moves axially back and forth cyclically along the cycloidal shaft 230, thereby enabling the suspension rope 250 to be evenly wound around the winding wheel 220.

[0033] To cooperate with the use of the cycloidal shaft 230, a pulley assembly 240 is provided. The pulley assembly 240 includes a pulley 241 and a mounting bracket 242. The mounting bracket 242 is rotatably connected to the pan-tilt body 100 (achieved through a bearing). The pulley 241 is rotatably arranged on the mounting bracket 242 (a rotating shaft is provided on the mounting bracket 242, and the pulley 241 is sleeved on the rotating shaft). A groove is provided on the outer circumferential surface of the pulley 241. After the suspension rope 250 is led out from the cycloidal shaft 230, it passes through the groove on the pulley 241 and then is fixedly connected to the hook 300.

[0034] Refer to Figure 8 and Figure 9 , Figure 8 is Figure 1 the oblique view of a partial wire-cutting device 400 of the pan-tilt in the figure, and Figure 9 is Figure 1Oblique view of the wire cutting device 400 of the middle-drop cloud platform. To enable the drone to detach in time when the suspension rope 250 is hung on a tree branch or wire, the wire cutting device 400 includes a second driving device 410, a second elastic element 420, a swing rod 430, a tool holder 440, and a cutter 450. In this embodiment, the second driving device 410 is a servo motor. One end of the swing rod 430 is fixed to the output end of the servo motor, and the other end of the swing rod 430 abuts against the tool holder 440. One end of the tool holder 440 is rotatably connected to the cloud platform body 100, and a cutter 450 is fixedly attached to the other end of the tool holder 440 by screws. A wire guiding hole 110 is provided on the cloud platform body 100. After the suspension rope 250 is led out from the pulley 241, it passes through the wire guiding hole 110 and then is fixedly connected to the hook 300. The cutting edge 441 of the cutter 450 faces the suspension rope 250. Thus, driven by the servo motor, the swing rod 430 can drive the tool holder 440 to swing, and the cutter 450 approaches the suspension rope 250, thereby cutting the suspension rope 250.

[0035] In another embodiment, the second driving device 410 is a linear motor. The tool holder 440 is fixed to the output end of the linear motor, and the cutting edge 441 faces the suspension rope 250. Through the linear motor, the cutting edge 441 can also cut the suspension rope 250.

[0036] To enable the cutter 450 to return to its original position and prevent the cutter 450 from operating by mistake and cutting the suspension rope 250, a second elastic element 420 is provided. In this embodiment, the second elastic element 420 is a second torsion spring. One end of the second torsion spring abuts against the cloud platform body 100, and the other end of the second torsion spring abuts against the tool holder 440. Under the action of the second torsion spring, the tool holder 440 drives the cutter 450 away from the suspension rope 250 and maintains a state of abutting against the cloud platform body 100.

[0037] In another embodiment, the second elastic element 420 can also be a compression spring, that is, one end of the compression spring abuts against the cloud platform body 100, and the other end abuts against the tool holder 440. The compression spring drives the tool holder 440 away from the suspension rope 250 and maintains a state of abutting against the cloud platform body 100.

[0038] Refer to Figures 5 to 7 , Figure 5 is Figure 1 the front view of the hook 300 of the middle-drop cloud platform, Figure 6 is Figure 1 the sectional view of the hook 300 of the middle-drop cloud platform, Figure 7 is Figure 1 the exploded view of the hook 300 of the middle-drop cloud platform. The hook 300 includes a moving arm 310, a fixed arm 320, a rotating shaft 330, a first elastic element 340, and an end cover 350. Among them, the lower end of the moving arm 310 is its first end (refer to Figure 5 ), and the upper end of the fixed arm 320 is its second end (refer to Figure 5), Similarly, the lower end of the fixed arm 320 is its first end (refer to Figure 5 ), and the upper end of the fixed arm 320 is its second end (refer to Figure 5 ). The second end of the movable arm 310 is rotatably connected to the second end of the fixed arm 320. The movable arm 310 can rotate relative to the fixed arm 320 about an axis in the front-rear direction, and moreover, the movable arm 310 can move relative to the fixed arm 320 in the up-down direction. The movable arm 310 is integrally in a "V" shape, and the fixed arm 320 is in a long strip shape. After the first end of the movable arm 310 is locked with the first end of the fixed arm 320, the movable arm 310 and the fixed arm 320 form a closed loop. The article is suspended on the movable arm 310 by a rope or a belt, and the hook 300 can stably carry the article. After the movable arm 310 rotates relative to the fixed arm 320 in the clockwise direction (refer to Figure 5 , that is, the second direction is the clockwise direction), the hook 300 opens, and the article can be put down.

[0039] To enable the first end of the movable arm 310 to be locked with the first end of the fixed arm 320, a lock hole 324 is provided at the first end of the fixed arm 320. The lower end surface of the lock hole 324 is an inclined surface (refer to Figure 6 ). A card slot is provided on this inclined surface. Among the bottom surfaces of the card slot, the surface tending to be horizontal is the first abutting surface 325. Correspondingly, a boss 311 is provided on the lower side of the first end of the movable arm 310 (refer to Figure 6 ), and a second abutting surface 318 is provided on the lower left side of the boss 311.

[0040] After the first end of the movable arm 310 extends into the lock hole 324, the boss 311 can be caught in the card slot. When the first abutting surface 325 and the second abutting surface 318 abut, the movable arm 310 cannot rotate relative to the fixed arm 320. When it is necessary to make the movable arm 310 rotate relative to the fixed arm 320 in the clockwise direction, the movable arm 310 needs to move upward. After the first abutting surface 325 and the second abutting surface 318 are disengaged from abutting, the first end of the movable arm 310 disengages from the lock hole 324, and the movable arm 310 rotates relative to the fixed arm 320 in the clockwise direction, and the hook 300 opens.

[0041] Thus, by hoisting the article on the movable arm 310, due to the action of the gravity of the article, the first abutting surface 325 and the second abutting surface 318 can maintain abutting, that is, the movable arm 310 moves relative to the fixed arm 320 in the first direction, which is the movement of the movable arm 310 relative to the fixed arm 320 in the downward direction. When the hook 300 needs to be unlocked, the movable arm 310 moves relative to the fixed arm 320 in the direction opposite to the first direction, which is the movement of the movable arm 310 relative to the fixed arm 320 in the upward direction.

[0042] To achieve the rotational connection between the second end of the boom 310 and the second end of the fixed arm 320, and at the same time enable the boom 310 to move relative to the fixed arm 320 in the up and down direction, a waist-shaped hole 322 is provided at the first end of the fixed arm 320. The length direction of the waist-shaped hole 322 is set in the up and down direction. Correspondingly, a rotating shaft 330 is fixed on the boom 310. After the rotating shaft 330 passes through the waist-shaped hole 322, the boom 310 can rotate relative to the fixed arm 320 about an axis in the front and back direction (refer to Figure 5 ), and can also move in the up and down direction (refer to Figure 5 ).

[0043] In this embodiment, the rotating shaft 330 is a screw, and a connecting groove 313 is provided at the second end of the boom 310. After the second end of the fixed arm 320 is placed in the connecting groove 313, the screw passes through the through hole 312 and the waist-shaped hole 322 in sequence, and then is threadedly connected and fixed to the boom 310.

[0044] In another embodiment, the waist-shaped hole 322 can also be replaced with an arc-shaped hole, and the arc-shaped hole can also achieve the rotational connection between the second end of the boom 310 and the second end of the fixed arm 320, and at the same time enable the boom 310 to move relative to the fixed arm 320 in the up and down direction.

[0045] To enable the boom 310 to automatically rotate clockwise relative to the fixed arm 320 when the item is separated from the working surface 317 of the boom 310 after the item lands (refer to Figure 5 ), a first elastic element 340 is provided. In this embodiment, the first elastic element 340 is a first torsion spring. The first torsion spring is sleeved on the rotating shaft 330. The first end of the first torsion spring abuts against the fixed arm 320, and the second end of the first torsion spring abuts against the boom 310. When the first end of the boom 310 extends into the locking hole 324, the first torsion spring is in a deformed state. When the item is separated from the working surface 317 of the boom 310, the first torsion spring drives the boom 310 to rotate clockwise relative to the fixed arm 320. At the same time, the convex platform 311 slides out of the clamping groove, and the boom 310 slides upward relative to the fixed arm 320. The second abutting surface 318 is separated from the first abutting surface 325, and finally the unlocking between the boom 310 and the fixed arm 320 is realized, and the closed ring formed by the boom 310 and the fixed arm 320 is opened.

[0046] To facilitate the installation of the first torsion spring, a receiving groove 323 is provided at the second end of the fixed arm 320. After the first torsion spring is placed in the receiving groove 323, first make the first end of the first torsion spring abut against the fixed arm 320 (by providing a blind hole on the fixed arm 320 and inserting the first end of the first torsion spring into the blind hole, the first end of the first torsion spring can be made to abut against the fixed arm 320). At the same time, a positioning hole 314 is provided at the second end of the moving arm 310. The front inner surface 315 of the positioning hole 314 has a regular hexagon as its orthographic projection. Correspondingly, the orthographic projection of the outer contour surface of the end cap 350 is also a regular hexagon. After the end cap 350 is embedded in the positioning hole 314, the second end of the first torsion spring abuts against the end cap 350 (by providing a blind hole on the end cap 350 to make the second end of the first torsion spring abut against the end cap 350), and the end cap 350 is finally locked with a screw (i.e., the rotating shaft 330).

[0047] Since the end cap 350 and the positioning hole 314 are regular hexagons that match each other, it is convenient to adjust the angle at which the end cap 350 is embedded in the positioning hole 314, facilitating the alignment and insertion of the blind hole on the end cap 350 with the second end of the first torsion spring. Through the detachable fixation of the end cap 350 and the moving arm 310, the installation and fixation of the first torsion spring can be facilitated.

[0048] In another embodiment, the orthographic projection of the front inner surface 315 of the positioning hole 314 and the orthographic projection of the outer contour surface of the end cap 350 can also be other regular polygons, such as equilateral triangles and squares.

[0049] In another embodiment, the end cap 350 can also be locked on the moving arm 310 with a screw to achieve the detachable fixation of the end cap 350.

[0050] In another embodiment, the first elastic element 340 can also be set as a compression spring, that is, an arc-shaped blind hole is provided at the second end of the moving arm 310, and the compression spring is placed in the arc-shaped blind hole. When the first end of the moving arm 310 extends into the locking hole 324, the compression spring is in a compressed state, and thus the moving arm 310 can also be made to automatically rotate clockwise relative to the fixed arm 320.

[0051] Refer to Figure 6 To prevent the first end of the moving arm 310 from protruding excessively from the locking hole 324, a first clamping point 316 is provided at the second end of the moving arm 310, and a second clamping point 326 is provided at the second end of the fixed arm 320. When the protrusion 110 is placed in the card slot, the first clamping point 316 abuts against the second clamping point 326.

[0052] To facilitate the hoisting of the hook 300, a lifting ring 321 is provided on the fixed arm 320, and the drone shell can be connected to the lifting ring 321 through a lifting rope, thereby realizing the installation of the hook 300.

[0053] The present invention also relates to a drone, which includes the above-mentioned automatically unlockable hook 300. A suspension rope is arranged on the drone and is connected to the suspension ring 321.

[0054] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
