The configuration of the locking assembly 500 may be selected as desired; referring to fig. 3 and 4, in the present embodiment, the locking assembly 500 includes a driving member 510, a latch 520 and a first elastic member 530, wherein the driving member 510 is assembled to the housing 300, and the driving member 510 is in transmission connection with the latch 520; the first elastic member 530 is disposed between the latch 520 and the housing 300; the first elastic member 530 is configured such that the latch 520 always has a tendency to block the rotational path of the hook 400, and the driving member 510 can drive the latch 520 to exit the rotational path of the hook 400 against the elastic force of the first elastic member 530. So arranged, when an article needs to be removed from the hook 400, the driving member 510 drives the latch 520 to exit the rotating path of the hook 400, so that the hook 400 can rotate to the unloading position to unload the article; when the articles do not need to be unloaded, the latch 520 is always blocked on the rotating path of the hook 400 under the action of the first elastic member 530, so as to ensure that the hook 400 is reliably locked at the mounting position by the latch 520, further ensure that the hook 400 can reliably mount the articles, and solve the problem that the articles are easy to accidentally drop from the hook 400.

It should be noted that, since only the driving member 510 is required to be energized to drive the latch 520 to exit the rotation path of the hook 400 when the article is loaded and unloaded, energy consumption can be effectively reduced.

It should be noted that, in some embodiments, when an article is hung on the hook 400, the driving member 510 may be used to drive the latch 520 to exit the rotation path of the hook 400, so that the hook 400 may swing flexibly, thereby facilitating the article to be hung on the hook 400, and after the article is hung, the latch 520 is reset to the rotation path blocking the hook 400 by using the elastic action of the first elastic member 530, so as to ensure that the hook 400 is reliably locked at the hanging position, and further ensure the stability of the hook 400 for hanging the article.

Further, the locking assembly 500 further comprises a transmission link 540, the driving member 510 is in transmission connection with the latch 520 through the transmission link 540, specifically, one end of the transmission link 540 is in transmission connection with the driving member 510, and the other end of the transmission link 540 is in rotational connection with the latch 520; the first elastic member 530 is connected between the housing 300 and the transmission link 540, and the first elastic member 530 is configured such that the transmission link 540 always has a tendency to drive the latch 520 to move to block the rotational path of the hanger 400. When the driving member 510 drives the transmission link 540 to swing, the transmission link 540 can drive the latch 520 to withdraw from the rotating path of the hook 400; and the transmission link 540 can drive the latch 520 to move to be blocked on the rotating path of the hook 400 under the elastic action of the first elastic member 530. By arranging the transmission connecting rod 540, the flexibility of the driving member 510 and the first elastic member 530 for driving the latch 520 to move is ensured, and the problem that the latch 520 is easy to be blocked is solved.

It should be appreciated that in other embodiments, the first elastic member 530 may also be connected between the driving member 510 and the transmission link 540, and the first elastic member 530 is configured such that the transmission link 540 always has a tendency to move the latch 520 to block the rotational path of the hanger 400.

Still further, the driving member 510 includes a steering engine, an axial extending direction of an output shaft of the steering engine and a moving direction of the latch 520 are disposed at an included angle, the included angle includes, but is not limited to, 90 °, 88 °, 93 ° and the like, and the output shaft of the steering engine is in transmission connection with a connection end of the transmission link 540, so as to drive a free end of the transmission link 540 to rotate around the connection end thereof, and through rotation of the transmission link 540, the latch 520 connected to the free end of the transmission link 540 is driven to move along a length extending direction thereof, so as to exit a rotating path of the hook 400.

Alternatively, the positioning post and the first torsion spring serving as the first elastic member 530 are both coaxially disposed with the output shaft of the driving member 510, and the first torsion arm and the second torsion arm of the first torsion spring respectively abut against the housing 300 and the transmission link 540. Of course, in other embodiments, at least one of the positioning post and the first torsion spring serving as the first elastic member 530 is not coaxially disposed with the output shaft of the driving member 510, and the connection manner of the first torsion arm of the first torsion spring and the housing 300, and the connection manner of the second torsion arm of the first torsion spring and the transmission link 540 may also be a socket connection or a clip connection, which is not limited herein.

In this way, when the driving member 510 drives the latch 520 to exit the rotation path of the hook 400, the hook 400 with the unlocked rotation trend can automatically rotate to the unloading position under the action of the second elastic member 401, so as to ensure labor-saving and easy operability of automatic unloading and unloading, that is, only the locking assembly 500 needs to be electrically controlled when the unloading is needed, and the hook 400 does not need to be controlled, so that the energy consumption is low.

Further, the hook 400 is rotatably connected with the housing 300 through the first rotating shaft 420, the second elastic member 401 is a second torsion spring, the second torsion spring is sleeved on the first rotating shaft 420, the first torsion arm of the second torsion spring is connected with the housing 300, and the second torsion arm of the second torsion spring is connected with the hook 400.

Optionally, the connection manner between the first torsion arm of the second torsion spring and the housing 300 and the connection manner between the second torsion arm of the second torsion spring and the hook 400 include, but are not limited to, abutting and clamping.

It should be appreciated that in other embodiments, to ensure stability of the hook 400 lifting an item, the second resilient member 401 may also be configured to cause the hook 400 to always have a tendency to rotate toward the mounting position.

In order to ensure that the hook 400 has a certain self-locking effect, the articles can be stably hoisted on the hook 400; referring to fig. 6, in the present embodiment, the hook 400 has a bending stress point 403 for hanging the article and an opening 402 for loading and unloading the article, the hook 400 can swing around a first axis 421 on two sides of a second axis 422, and the first axis 421 is perpendicular to the second axis 422; the bending stress points 403 and the openings 402 are distributed on both sides of the second axis 422. In this way, the stress points of the hanging hook 400 for hanging the articles are distributed on one side of the first rotating shaft 420, and the openings 402 of the hanging hook 400 are distributed on the other side of the first rotating shaft 420, so that when the articles are hung on the hanging hook 400, the gravity of the articles enables the hanging hook 400 to have a tendency of rotating towards the mounting position, a certain self-locking effect can be formed, and the stability of the hanging hook 400 for hanging the articles is improved. In addition, since the hanger 400 tends to rotate toward the mounting position when hanging the article, the latch 520, which is blocked on the path of the hanger 400 toward the unloading position, does not bear the weight of the article, and the locking assembly 500 serves only as a secondary safety for preventing the article from falling off, thereby improving the service life of the latch 520.

Optionally, the hook 400 includes a pivot portion 410, a first connecting rod 411, a second connecting rod 412, and a third connecting rod 413, where the first connecting rod 411, the second connecting rod 412, and the third connecting rod 413 are sequentially connected at an included angle, one end of the first connecting rod 411 away from the second connecting rod 412 is connected with the pivot portion 410, the pivot portion 410 is connected with the housing 300 through a first rotation shaft 420, a connection position between the second connecting rod 412 and the third connecting rod 413 is a bending stress point 403 for hanging off an article, and one ends of the pivot portion 410 and the third connecting rod 413 away from the second connecting rod 412 form an opening 402 of the hook 400. In this way, the article can be reliably suspended at the bending stress point 403 between the second link 412 and the third link 413.

To further ensure the stability of the article hanging from the hanger 400; referring to fig. 3, 4 and 5, the lifting mechanism 200 of the present embodiment further includes a baffle 600, where the baffle 600 is rotatably connected to the housing 300, and the baffle 600 is used to block the articles lifted from the hanger 400 from being separated from the hanger 400.

Further, the flap 600 is rotatable relative to the housing 300 between a closed position and an open position, and when the flap 600 is in the closed position, the flap 600 blocks the opening 402 of the hanger 400 to block an item suspended from the hanger 400 from exiting the hanger 400, and when the flap 600 is in the open position, the flap 600 opens the opening 402 of the hanger 400 to facilitate loading and unloading of the item from the opening 402 to the hanger 400. By the arrangement, on one hand, the problem that articles are blocked from being separated from the hooks 400 by the baffle 600 is solved, the stability of the hooks 400 for hanging articles is improved, and on the other hand, the arrangement of the baffle 600 is avoided from interfering with loading and unloading of the articles on the hooks 400.

The handling mechanism 200 further comprises a third elastic member 601, the third elastic member 601 being arranged between the flap 600 and the housing 300, the third elastic member 601 being configured such that the flap 600 always has a tendency to rotate to the closed position.

The configuration of the adjustment assembly 710 may be selected as desired; in this embodiment, the adjusting assembly 710 includes a cam 711 and a fourth elastic member 712, the cam 711 is rotatably disposed on the housing 300, a routing channel 713 is formed between the cam 711 and the housing 300, and the lifting rope 700 is movably disposed in the routing channel 713 in a penetrating manner; the cam 711 can rotate to an unlocking position and a locking position relative to the housing 300, when the cam 711 rotates to the unlocking position, the lifting rope 700 can slide in the wiring channel 713, and when the cam 711 rotates to the locking position, the cam 711 can press the lifting rope 700 in the wiring channel 713 against the housing 300; a fourth elastic member 712 is provided between the cam 711 and the housing 300 for making the cam 711 always have a tendency to rotate toward the locking position; wherein, when the lifting rope 700 slides in the first direction a in the routing channel 713, the lifting rope 700 can overcome the elastic action of the fourth elastic piece 712 to rotate the cam 711 towards the unlocking position, and when the lifting rope 700 slides in the second direction b in the routing channel 713, the lifting rope 700 can rotate to the locking position, and the first direction a is opposite to the second direction b. The arrangement of the fourth elastic member 712 and the cam 711 can ensure easy operability of the length adjustment of the suspension rope 700, and can stably maintain the adjusted hanging-off length of the suspension rope 700 to ensure stability; also, as the force pulling the suspension cord 700 to slide in the second direction b within the routing channel 713 is greater, the greater the force with which the cam 711 is pressed against the suspension cord 700, the more reliably the suspension cord 700 can be locked.

It should be appreciated that in other embodiments, the adjustment assembly 710 may not include the fourth resilient member 712, the cam 711 may be locked in the locked position by a fastener such as a bolt, or the cam 711 may be unlocked from the locked position by unscrewing a fastener such as a bolt and rotatable to the unlocked position; alternatively, in other embodiments, the adjustment assembly 710 may not include the fourth resilient member 712, but rather a motor in driving communication with the cam 711 for driving the cam 711 between the unlocked and locked positions.

Further, the fourth elastic member 712 is a fourth torsion spring, and the cam 711 is rotatably connected to the housing 300 through a third rotation shaft 716; the fourth torsion spring is sleeved on the third rotating shaft 716, a first torsion arm of the fourth torsion spring is connected with the shell 300, and a second torsion arm of the fourth torsion spring is connected with the cam 711; by this arrangement, the cam 711 always has a tendency to rotate to the locked position by the elastic action of the fourth torsion spring.

Optionally, the connection manner between the first torsion arm of the fourth torsion spring and the housing 300 and the connection manner between the second torsion arm of the fourth torsion spring and the hook 400 include, but are not limited to, abutting and clamping.

It should be appreciated that in other embodiments, the fourth elastic member 712 may also be a tension spring or the like, which is not specifically limited herein.

Alternatively, in order to improve stability of the cam 711 in locking the hanger rope 700, the surface of the cam 711 is provided with teeth, and in particular, the surface of the cam 711 contacting the hanger rope 700 is provided with teeth to increase friction between the cam 711 and the hanger rope 700 by the arrangement of the teeth, thereby improving locking reliability. Of course, in other embodiments, the locking reliability may also be improved by increasing the roughness of the contact surface of the cam 711 and the lifting rope 700, increasing the friction between the cam 711 and the lifting rope 700; alternatively, grooves may be provided on the surface of the cam 711 to increase friction between the cam 711 and the hanger rope 700, thereby improving locking reliability.

In order to make the lifting rope 700 have a certain self-locking performance, the casing 300 is provided with a first routing hole 714 and a second routing hole 715, the first routing hole 714 and the second routing hole 715 are connected with each other and are distributed in an included angle, the lifting rope 700 passing through the routing channel 713 can sequentially pass through the second routing hole 715 and the first routing hole 714, and the axial direction of the first routing hole 714 is set in an included angle with the direction of the rotating shaft of the hook 400, that is, the axial direction of the first routing hole 714 is set in an included angle with the first axis 421. By the arrangement, after the lifting rope 700 sequentially passes through the second wiring hole 715 and the first wiring hole 714, the lifting rope 700 is connected with the cross beam 120, and one end, connected with the cross beam 120, of the lifting rope 700 can straighten along the axial direction of the first wiring hole 714, so that the stability of hanging articles by the lifting mechanism 200 is ensured; moreover, when the lifting mechanism 200 lifts an article, the end of the lifting rope 700 extending from the first routing hole 714 and connected to the cross beam 120 is pulled, so that the lifting rope 700 in the routing channel 713 has a tendency to move along the second direction b, thereby enabling the cam 711 to be locked at the locking position more reliably, ensuring that the lifting rope 700 can be locked reliably under the action of the cam 711, further ensuring the stability of the hanging length of the lifting rope 700, and improving the problem of sliding down of the article hanging on the lifting mechanism 200 due to unstable locking of the lifting rope 700.

Alternatively, the axis extending direction of the first routing hole 714 is perpendicular to and intersects with the extending direction of the rotation axis (i.e. the first axis 421) of the hook 400, and the rotation axis of the cam 711 is coincident with or parallel to the axis extending direction of the first routing hole 714; so arranged, the direction of force of the end of the lifting rope 700 extending from the first routing hole 714 and connected with the cross beam 120 is the same as the direction of force of the hanging hook 400 for hanging the article, so that the lifting mechanism 200 can be used for stably lifting the article; and when the lifting mechanism 200 lifts an article, the lifting rope 700 in the routing channel 713 has a tendency to move in the second direction b, so that the lifting rope 700 can be reliably locked by the cam 711.

Further, the extending direction of the axis of the first wiring hole 714 and the extending direction of the rotation axis of the cam 711 are vertical; the first axis 421 is transverse. By this arrangement, the stability of hanging off the article by the lifting mechanism 200 can be ensured.

Alternatively, the first direction a and the second direction b are distributed parallel to the first axis 421. This arrangement facilitates ensuring that the lifting rope 700 has a tendency to move in the second direction b within the routing channel 713 when the lifting mechanism 200 lifts an item, thereby further ensuring that the lifting rope 700 is reliably locked under the action of the cam 711.

In one embodiment, an adjustment assembly for adjusting the length of the line may also be provided on the cross beam 120 of the landing gear 100 so that a user may make adjustments to the length of the line at both ends of the lifting line 700.

When the lifting mechanism 200 is collided, at least one of the first cavity 321 and the second cavity 331 on two sides of the stressed main body 310 is firstly collided, namely the stressed main body 310 positioned between the first cavity 321 and the second cavity 331 is not easy to contact with the outside, so that obstacles such as branches are not easy to hook in the lifting process of the unmanned aerial vehicle, the obstacles are not easy to collide, the stability of the hook 400 rotationally connected with the stressed main body 310 can be ensured, and the stability of the hook 400 for mounting articles is ensured.

Further, the force-receiving body 310 is provided with a slot 311, and a part of the hook 400 extends into the slot 311. So arranged, a portion of the hanger 400 is embedded within the force-receiving body 310 to further reduce the likelihood of the hanger 400 being impacted and to ensure stability of the hanger 400 for mounting items.

Still further, the baffle 600 is rotatably connected to the force-receiving body 310, that is, the baffle 600 is rotatably connected to the force-receiving body 310 through the second rotation shaft 610, and a portion of the baffle 600 extends into the slot 311; so arranged, a portion of the flap 600 is embedded within the interior of the force-receiving body 310 to reduce the likelihood of the flap 600 being impacted and to ensure that the flap 600 is able to reliably block items from falling off the hanger 400.

Alternatively, both ends of the slot 311 in the length extending direction penetrate the force-receiving body 310; this arrangement facilitates the rotation of the hook 400 and the flap 600 when needed to remove and mount articles from the hook 400 without interference.
