The term "inner and outer" refers to the inner and outer parts of the relevant component. Furthermore, terms such as "first," "second," and the like, are used herein to distinguish one element from another, and are not necessarily sequential or significant.

As shown in fig. 1-4, the present disclosure provides acontainer drop mechanism 100. Thecontainer dropping mechanism 100 comprises acontainer 10, a supportingmember 20 and a locking structure, wherein thecontainer 10 is provided with a containingcavity 30 for inserting one end (the upper end of thecontainer 200 shown in fig. 2) of thecontainer 200, the supportingmember 20 is provided with a first end and a second end which are opposite, the first end (the upper end of the supportingmember 20 shown in fig. 1) is provided with a supportinglimit bulge 21, for supporting thecontainer 200 to be exposed to the other end of the receiving cavity 30 (the lower end of thecontainer 200 shown in fig. 2), the second end (the upper end of the supportingmember 20 shown in fig. 1) is hinged to the receivingmember 10, so that the supportinglimit protrusion 21 can be located at a position for supporting thelimit container 200 or at a position for avoiding thecontainer 200 from entering and exiting theaccommodating cavity 30, the locking structure is used for locking the supportingmember 20 at the position for supporting thelimit container 200, and the supportingmember 20 is provided with aclamping part 26 for being matched with themanipulator 300.

Through the technical scheme, the supportingpiece 20 can rotate around the hinge axis of the supportingpiece 20 and theaccommodating piece 10, so that the supportingpiece 20 has a supporting position and an avoiding position, in the supporting position, the supporting limitingprotrusion 21 supports and limits thecontainer 200 to prevent thecontainer 200 from being separated from theaccommodating cavity 30, at the moment, the supportingpiece 20 and theaccommodating piece 10 fix the position of thecontainer 200 together, and thecontainer 200 can be reliably transported by using thecontainer throwing mechanism 100. In the retracted position, thesupport member 20 is rotated at an angle about its center of rotation relative to the receivingmember 10, as shown in fig. 3, and thesupport limit projection 21 is moved out of the path of thecargo container 200 to retract thecargo container 200 into and out of thereceiving cavity 30, thereby allowing loading or dropping of thecargo container 200.

By rotating the supportingmember 20, the supportingmember 20 can be switched between a position for supporting thespacing container 200 and a position for avoiding thecontainer 200, thereby realizing loading, transportation and release of thecontainer 200. Compared with the technical scheme that the steering engine is adopted to realize the loading and unloading of the container in the related art, thecontainer throwing mechanism 100 provided by the disclosure has at least the following three advantages: first, because the steering wheel loading and unloading structure has been saved, therefore can simplify the structure of packingbox input mechanism 100, lighten its weight, especially when packingbox input mechanism 100 uses in food delivery unmanned aerial vehicle field, can the very big degree lighten the weight at unmanned aerial vehicle end. Secondly, reduce the control degree of difficulty at the unmanned aerial vehicle end, avoid appearing producing electromagnetic interference between other equipment and the steering wheel loading and unloading structure on the unmanned aerial vehicle, can increase the reliability of unmanned aerial vehicle complete machine operation, increase the reliability of packingbox input mechanism 100 work. Third, the support-limitingprotrusions 21 support and limit the lower end of thecargo box 200, for example, at the edges of the two sides of the bottom of thecargo box 200, so as to support and lift thecargo box 200. The carton is generally used to packingbox 200 especially the serving box, and the arris department structural strength of carton is high, does the support in these two places, compares in the current mode that adopts steering wheel axle to support and block the packing box lateral wall, and thedifficult packing box 200 that makes of this disclosed support lifting mode warp to difficult emergence is because ofpacking box 200 warp the condition that leads to packingbox 200 drops.

Due to the locking structure, the supportingpiece 20 can be locked at the position for supporting thespacing container 200, and thecontainer 200 can be reliably fixed. Thus, during transportation, thesupport member 20 and the receivingmember 10 can be prevented from being accidentally rotated by an external force such as a thrust of thecargo box 200, and thecargo box 200 can be prevented from being accidentally dropped.

Due to theclamping portion 26, the matching of themanipulator 300 and thesupport 20 is facilitated, and when thecargo box 200 needs to be unlocked, themanipulator 300 can be rapidly matched with thesupport 20 to timely drive thesupport 20 to rotate to the avoiding position.

There are many ways in which thesupport member 20 can be driven to rotate relative to the receivingmember 10. For example, thesupport member 20 may be driven to rotate about the receivingmember 10 by arobot 300 located at the airport (see discussion below for details). Alternatively, thesupport member 20 may be manually rotated relative to the receivingmember 10 at the loading and unloading station of thecontainer 200.

The present disclosure is not limited to a particular configuration and shape of thepod 10, which may have any suitable configuration and shape. As shown in fig. 1, in one embodiment of the present disclosure, the receivingmember 10 is configured as a U-shaped member including atop plate 11 andside plates 12 oppositely disposed at both ends of thetop plate 11, and the number of the supportingmembers 20 is two, and each of the supportingmembers 20 is hinged with thecorresponding side plate 12. In the present embodiment, thetop panel 11 and theside panels 12 of the U-shaped member together define a receiving space, and as shown in fig. 2, when thecargo box 200 is mounted in place, the top side of thecargo box 200 may contact the inner wall of thetop panel 11, the upper portions of the two side walls of thecargo box 200 may contact the inner wall of theside panels 12, the lower portions of the two side walls of thecargo box 200 may contact the inner wall of the supportingmember 20, and the supporting restrictingprotrusions 21 may be supported on thebottom surface 201 of thecargo box 200. In this way, the receivingmembers 10 and the supportingmembers 20 together lock the position of thecargo box 200, allowing for reliable transport of thecargo box 200.

As shown in fig. 4, the receivingmember 10 is formed as a U-shaped member, which is advantageous in that the receivingmember 10 having a U-shape can be applied tocontainers 200 having different lengths (here, the left-right direction of the drawing of fig. 4 is the longitudinal direction of the container 200), and the versatility of the receivingmember 10 can be improved.

In other embodiments of the present disclosure, the receivingmember 10 may be a C-shaped member or the like, depending on the shape of thecargo box 200 and the like, which is not limited by the present disclosure.

In addition, it is understood that in other embodiments of the present disclosure, thecontainer 10 may be configured as a rectangular parallelepiped box with an open lower end, and the lower end of two opposite side walls of the rectangular parallelepiped is provided with thesupport 20, and thesupport 20 is hinged with the side walls of the rectangular parallelepiped box, so that the support and avoidance of thecargo box 200 can be realized.

Likewise, the present disclosure is not limited to the specific structure and shape of thesupport member 20. Alternatively, as shown in fig. 1, in one embodiment of the present disclosure, thesupporter 20 may include an L-shapedportion 22, the L-shapedportion 22 being configured by connecting afirst plate 231 and asecond plate 232, an end of thefirst plate 231 remote from the second plate 232 (i.e., an upper end of thefirst plate 231 as shown in fig. 1) being connected to the receivingmember 10, and thesecond plate 232 being configured to support thestopper protrusion 21. When thebrace 20 is in the bracing position, thebottom surface 201 of thecontainer 200 is braced against the upper surface of thesecond panel 232 and the underlying portion of the side wall of thecontainer 200 contacts the inner wall of thefirst panel 231, ensuring a secure bracing of thecontainer 200 so that thecontainer 200 can be securely held by thebrace 20 and thereceiver 10.

In the present embodiment, particularly, in the embodiment shown in fig. 1 and 2, the upper end of thefirst plate 231 may be hinged with the lower end of theside plate 12 of the receivingmember 10.

The present disclosure does not limit the specific structure of the locking structure as long as reliable locking of thesupport member 20 and the receivingmember 10 can be achieved.

As shown in fig. 2 to 4, in one embodiment of the present disclosure, the locking structure includes atorsion spring 50, the supportingmember 20 is hinged to the accommodatingmember 10 through ahinge shaft 40, and thetorsion spring 50 is sleeved on thehinge shaft 40 to provide a locking torsion force to lock the supportingmember 20 at a position supporting thecontainer 200. That is, thesupport limiting protrusion 21 of thesupport member 20 is maintained at a position to support thebottom surface 201 of the limitingcargo box 200 by the torsion force of thetorsion spring 50, thereby achieving reliable transportation of thecargo box 200. When it is desired to load or release thecontainer 200, thesupport member 20 is driven to rotate about thehinge shaft 40 against the torsion force of thetorsion spring 50 to avoid thecontainer 200 from entering or exiting theaccommodating cavity 30. The locking structure is simple in structure and reliable in locking.

As shown in fig. 4, in the present embodiment, agap 13 is disposed on a side wall of the accommodatingmember 10, two ends of thehinge shaft 40 are respectively connected to the side wall of thegap 13, asleeve structure 23 is disposed on the supportingmember 20, and the supportingmember 20 is rotatably sleeved on thehinge shaft 40 through thesleeve structure 23. Alternatively, as shown in fig. 4, thesleeve structure 23 may be formed at the upper end of thefirst plate 231 of the L-shapedportion 22.

Further, as shown in fig. 4, thetorsion spring 50 may be a double torsion spring, thetorsion spring 50 includes afirst spring body 51, asecond spring body 52, and an arched connectingrod 53 connected between thefirst spring body 51 and thesecond spring body 52, thefirst spring body 51 and thesecond spring body 52 are spaced and sleeved on thehinge shaft 40, thesleeve structure 23 is located between thefirst spring body 51 and thesecond spring body 52, the arched connectingrod 53 is pressed against the outer wall of the supporting member 20 (i.e., the side wall of the supportingmember 20 away from the cargo box 200) to provide a torsion force for keeping the supportingmember 20 in the supporting position, one end of thefirst spring body 51 away from thesecond spring body 52 is fixedly connected to the accommodatingmember 10, and one end of thesecond spring body 52 away from thefirst spring body 51 is fixedly connected to the accommodatingmember 10. The double torsion spring structure is advantageous in providing a larger torsion force, and is advantageous in ensuring the reliability of the locking of thesupport member 20 to thecargo box 200, and, as shown in fig. 4, since the arched connectingrods 53 are integrally pressed against thefirst plate 231 of thesupport member 20, the locking torsion force applied to thesupport member 20 by thetorsion spring 50 is more balanced in the width direction (left and right directions in the drawing direction of fig. 4) of thesupport member 20, and is advantageous in improving the uniformity of the pressure applied to thecargo box 200 by thesupport member 20, and thus thecargo box 200 can be effectively prevented from being locally pressed by thesupport member 20.

In summary, in the present embodiment, the design of thenotch 13 on the accommodatingmember 10 is matched with the arrangement of the double torsion springs, which is not only beneficial to improving the reliability of the locking structure for locking thecargo box 200, but also beneficial to forming the extrusion protection for thecargo box 200, and the structure is simple.

Alternatively, as shown in fig. 2 and 4, thehinge shaft 40 may be horizontally disposed in a width direction of the supporter 20 (a left-right direction of the drawing of fig. 4) to facilitate the rotation of thesupporter 20 about the receivingmember 10. In other embodiments of the present disclosure, thehinge shaft 40 may be slightly inclined.

It is understood that in other embodiments of the present disclosure, two torsion springs may be used instead of the double torsion spring structure. Instead of separately providing thehinge shaft 40 and thesleeve structure 23, two cylindrical sections, each rotatably connected to a side wall of the above-mentionedgap 13, may be provided at corresponding positions of the supportingmember 20 instead of thehinge shaft 40. In this way, thesupport element 20 can be rotated relative to the receivingelement 10 by means of the two cylindrical segments.

It should be noted that the present disclosure does not limit the specific shape and structure of the locking structure, and in other embodiments of the present disclosure, the locking structure may include a spring, one end of which is connected to the outer wall of the accommodatingmember 10, and the other end of which abuts against the outer wall of the supportingmember 20, so as to provide an elastic abutting force to lock the supportingmember 20 in a position for supporting thecontainer 200.

Specifically, when a spring is used as the locking structure, referring to fig. 1, an upper end of the spring may be connected to an outer side wall of theside plate 12 of the receivingmember 10, and a lower end of the spring may be connected in abutment with an upper side wall of a connecting plate 24 (the connectingplate 24 is described below) of the supportingmember 20. In this way, thesupport member 20 can be retained in position to restrain thecargo box 200 as needed by the elastic resisting force provided by the elasticity. When it is required to load or release thecontainer 200, the supportingmember 20 is driven to rotate about thehinge shaft 40 against the elastic urging force of the spring to avoid thecontainer 200 from entering or exiting theaccommodating chamber 30.

In addition, in other embodiments of the present disclosure, the locking structure may be an electronic lock disposed on an outer wall of the receivingmember 10, and when the supportingmember 20 is located at the supporting position, a locking rod of the electronic lock protrudes downward to be pressed against the outer wall of the supporting member 20 (e.g., against the first plate 231), so that the supportingmember 20 cannot rotate relative to the receivingmember 10, thereby achieving locking of the position of thecargo supporting member 20. When it is desired to load or release thecontainer 200, the locking bar of the electronic lock can be retracted upwardly to allow thesupport member 20 to rotate relative to the receivingmember 10 to clear thecontainer 200 from entering or exiting the receivingcavity 30.

Alternatively, the supportingmember 20 can form a damped rotation with the receivingmember 10, and both rely on a damping force to ensure that the supportingmember 20 is in the supporting position, and when thecargo box 200 needs to be loaded or dropped, the damping force can be overcome by an external force to realize the rotation of the supportingmember 20. It will be appreciated that when the damping force is sufficiently large, thesupport members 20 can be secured against thecargo box 200.

As shown in fig. 1 to 4, in an embodiment of the present disclosure, aconnection plate 24 is further disposed on an outer wall of the support member 20 (i.e., a side wall of thesupport member 20 away from the cargo box 200), and a clampingportion 26 is disposed at an end of theconnection plate 24 away from thesupport limiting protrusion 21. In operation, as shown in fig. 2 and 3, themanipulator 300 is clamped on the clampingportion 26 of the connectingplate 24, and when themanipulator 300 moves in the left-right direction, the supportingmember 20 can rotate around thehinge shaft 40, so that the supportinglimit protrusion 21 is far away from thecontainer 200, and the container is unlocked, thereby facilitating loading and releasing of thecontainer 200.

The present disclosure does not limit the specific structure of the clampingportion 26, and in one embodiment, as shown in fig. 1, the clampingportion 26 may be formed as a cylindrical structure, and the gripping end of themanipulator 300 may be a chuck structure (not shown), so that the cylindrical structure can be engaged with the chuck structure, and themanipulator 300 and thesupport member 20 can be reliably and conveniently connected.

In addition, as shown in fig. 4, thefastening portion 26 may be a convex pillar vertically disposed on the connectingplate 24, and in this case, a sleeve structure may be disposed on themanipulator 300 to engage with the convex pillar in an inserting manner, so as to facilitate connection between themanipulator 300 and the supportingmember 20.

As shown in fig. 1 to 3, the connectingplate 24 may extend from the outer wall of thefirst plate 231 toward a direction away from thesecond plate 232, and in order to increase the structural strength of thestay 20, a reinforcingrib 25 may be provided between thefirst plate 231 and the connectingplate 24, and alternatively, the reinforcingrib 25 may be a triangular rib.

In the present disclosure, when thecargo box 200 is loaded, since thesupport member 20 rotates to the supporting position by itself after themanipulator 300 releases thesupport member 20, there may be an impact between the inner wall of thesupport member 20 and the outer wall of thecargo box 200, and in order to solve this problem, an elastic pad may be disposed on the inner wall of the support member 20 (i.e., the side wall of thesupport member 20 facing the cargo box 200) to buffer the impact between thesupport member 20 and thecargo box 200, which is beneficial to avoiding damage to thecargo box 200.

According to another aspect of the present disclosure, there is provided a drone comprising a body to which a receivingmember 10 is mountable and the cargobox dropping mechanism 100 described above.

The present disclosure does not limit the mounting position and mounting manner of the receivingmember 10 on the machine body. In one embodiment, the receivingmember 10 may optionally be secured to the landing gear of the drone, for example by adhesive bonding.

When the cargo box is installed, the outer wall of thetop plate 11 of the accommodatingmember 10 may be connected to the machine body, so that the U-shaped member is arranged in the vertical direction, the opening of the U-shaped member faces downward, and the supportingmember 20 is located at the lower end of the accommodatingmember 10, so that thecargo box 200 is fixed to the cargobox dropping mechanism 100, which is beneficial to ensuring the reliability of fixing thecargo 200.

According to yet another aspect of the present disclosure, there is provided a container handling system comprising arobot 300 and a drone as described above. Therobot 300 is used for driving thesupport member 20 to rotate so as to realize the support limit or avoidance of thecontainer 200, and therobot 300 may be a robot arranged in an airport field.

Further, as shown in fig. 3, there may be tworobots 300, and the tworobots 300 correspond to the twosupports 20 one by one, that is, eachrobot 300 is responsible for driving the rotation of onesupport 20. Thus, when thecargo box 200 is unlocked, as shown in fig. 3, two manipulators may be used to simultaneously work so that thesupport limit protrusions 21 of the twosupporters 20 are far from thecargo box 200, which is efficient and facilitates the unlocking of thecargo box 200.

Wherein,packing box 200 can be for the food delivery case, like this, when using unmanned aerial vehicle to carry out unmanned food delivery, utilizes the packing box of setting on unmanned aerial vehicle to put in the mechanism, can reliably deliver to the food delivery case, can alleviate the weight of unmanned aerial vehicle end moreover, is favorable to promoting its transportation mileage. Meanwhile, the food delivery box is not easy to be damaged.
