[0032] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended for description and explanation of the present disclosure and are not intended to limit the present disclosure.

[0033] In the present disclosure, the orientation words such as "upper" and "lower" are generally defined based on the state of the unmanned aerial vehicle when it normally flies horizontally, unless otherwise stated. This is only for the convenience of describing the present disclosure and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, a particular orientation configuration and operation, and therefore cannot be understood as a limitation on the present disclosure.

In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0035] As a first aspect of the present disclosure, as shown in Figures 1 to 6 The present disclosure provides an unmanned aerial vehicle 100, comprising a fuselage 1 and a cargo cabin 2 connected to the fuselage 1, the cargo cabin 2 comprising a main body 21, a first door 22 and a second door 23, the main body 21, the first door 22 and the second door 23 collectively defining a receiving cavity 3 for accommodating goods 300, the main body 21 having an opening 213 through which the goods 300 can enter the receiving cavity 3, the first door 22 and the second door 23 being movably connected to the main body 21, and the first door 22 and the second door 23 being movable towards or away from each other to close or expose the opening 213.

[0036] In the process of taking the goods 300 from the load bearing structure 201 by the unmanned aerial vehicle 100 described above, the first door 22 and the second door 23 can first move away from each other to expose the opening 213 through which the goods 300 pass, so that the goods 300 enter the receiving cavity 3 through the opening 213. After the goods 300 enter the receiving cavity 3, the first door 22 and the second door 23 move towards each other, and the first door 22 and the second door 23 extend between the bottom of the goods 300 and the load bearing structure 201 while closing the opening 213, thereby separating the goods 300 from the load bearing structure 201, so that the goods 300 are supported by the side of the first door 22 and the second door 23 close to the receiving cavity 3, to completely transfer the goods 300 from the load bearing structure 201 to the receiving cavity 3. When the first door 22 and the second door 23 are in the position of completely closing the opening 213, the goods 300 are located in the receiving cavity 3 and are supported by the first door 22 and the second door 23.

[0037] In the process of placing the goods on the load bearing structure 201 by the unmanned aerial vehicle 100 described above, the first door 22 and the second door 23 move away from each other, and the goods 300 can pass through the opening 213 to be supported by the load bearing structure 201 under the action of gravity while the opening 213 is gradually exposed.

[0038] In the process of placing the goods on the load bearing structure 201 by the unmanned aerial vehicle 100 described above, the first door 22 and the second door 23 move away from each other, and the goods 300 can pass through the opening 213 to be supported by the load bearing structure 201 under the action of gravity while the opening 213 is gradually exposed.

[0039] By the technical solution, the first hatch 22 and the second hatch 23 of the unmanned aerial vehicle 100 can not only open and close the opening 213 of the accommodating cavity 3, but also shovel the goods 300 from the carrying structure 201 into the accommodating cavity 3 in the process of closing the opening 213. Thus, the goods transfer between the carrying structure 201 and the unmanned aerial vehicle 100 can be realized without setting a separate goods grabbing mechanism, so that the structure of the unmanned aerial vehicle 100 can be simplified, the production cost of the unmanned aerial vehicle 100 can be reduced, and the space utilization of the unmanned aerial vehicle 100 can be improved. Also, the self-weight of the unmanned aerial vehicle 100 can be reduced, and the endurance mileage of the unmanned aerial vehicle 100 can be improved.

[0040] In order to facilitate the first hatch 22 and the second hatch 23 to extend between the bottom of the goods 300 and the carrying structure 201 supporting the goods 300 to load the goods 300 into the accommodating cavity 3, optionally, as shown in Figure 5 The first hatch 22 includes a first hatch body 221 and a first thinning portion 222, the first thinning portion 222 is located at one end of the first hatch body 221 close to the second hatch 23, and the thickness of the first thinning portion 222 gradually decreases from one end of the first thinning portion 222 close to the first hatch body 221 to the other end of the first thinning portion 222 away from the first hatch body 221. The second hatch 23 includes a second hatch body 231 and a second thinning portion 232, the second thinning portion 232 is located at one end of the second hatch body 231 close to the first hatch 22, and the thickness of the second thinning portion 232 gradually decreases from one end of the second thinning portion 232 close to the second hatch body 231 to the other end of the second thinning portion 232 away from the second hatch body 231.

[0041] The first thinning portion 222 and the second thinning portion 232 with a decreasing thickness are arranged at opposite ends of the first hatch body 221 and the second hatch body 231 respectively, and in the process of moving the first hatch 22 and the second hatch 23 towards each other, the first thinning portion 222 and the second thinning portion 232 can first extend into the small gap between the goods 300 and the carrying structure 201, which is beneficial to improve the success rate of the first hatch 22 and the second hatch 23 to shovel the goods 300 into the accommodating cavity 3.

[0042] The specific structure of the first thinning portion 222 and the second thinning portion 232 is not limited in the present disclosure, for example, Figure 5As shown, in one embodiment provided in this disclosure, the surface of the first thinned portion 222 facing the receiving cavity 3 is inclined, such that the thickness of the first thinned portion 222 gradually decreases from the end of the first thinned portion 222 near the first door body 221 to the end of the first thinned portion 222 away from the first door body 221. Similarly, the surface of the second thinned portion 232 facing the receiving cavity 3 is inclined, such that the thickness of the second thinned portion 232 gradually decreases from the end of the second thinned portion 232 near the second door body 231 to the end of the first thinned portion 222 away from the second door body 231. The thinner end of the first thinning portion 222 and the second thinning portion 232 can first extend into the gap between the cargo 300 and the supporting structure 201 when the first hatch 22 and the second hatch 23 move towards each other. Since the surfaces of the first thinning portion 222 and the second thinning portion 232 facing the receiving cavity 3 are inclined, these inclined surfaces can also serve as guide surfaces during the movement of the first hatch 22 and the second hatch 23, so that the cargo 300 can move from the supporting structure 201 to the first hatch body 221 and the second hatch body 231.

[0043] In another embodiment provided in this disclosure, the surface of the first thinned portion 222 facing the receiving cavity 3 is inclined, and the surface of the first thinned portion 222 away from the receiving cavity 3 is also inclined, so that the thickness of the first thinned portion 222 gradually decreases from the end of the first thinned portion 222 near the first hatch body 221 to the end of the first thinned portion 222 away from the first hatch body 221. The surface of the second thinned portion 232 facing the receiving cavity 3 is inclined, and the surface of the second thinned portion 232 away from the receiving cavity 3 is also inclined, so that the thickness of the second thinned portion 232 gradually decreases from the end of the second thinned portion 232 near the second hatch body 231 to the end of the first thinned portion 222 away from the second hatch body 231.

[0044] This disclosure does not limit the specific structure of the first and second hatches. In one embodiment provided by this disclosure, the first hatch can be a first hatch panel and the second hatch can be a second hatch panel. The first and second hatch panels are disposed at the opening 213 and are movably connected to the main body to close or expose the opening 213.

[0045] In another embodiment provided in this disclosure, such as Figure 4 As shown, both the first hatch 22 and the second hatch 23 are formed as roller shutter structures. The UAV 100 also includes a first roller 4, a second roller 5, a first drive member, and a second drive member. The first hatch 22 is connected to the first roller 4 and can be wound around the first roller 4. The second hatch 23 is connected to the second roller 5 and can be wound around the second roller 5. The first drive member is connected to the first roller 4 and is used to drive the first roller 4 to rotate. The second drive member is connected to the second roller 5 and is used to drive the second roller 5 to rotate.

[0046] When it is needed to cover the opening 213, the first driving member can drive the first reel 4 to rotate in one direction, and the second driving member can drive the second reel 5 to rotate in one direction, so that the first reel 4 and the second reel 5 release the first hatch 22 and the second hatch 23, i.e., the first hatch 22 and the second hatch 23 are unfolded to cover the opening 213 of the main body 21 and at the same time shovel the cargo. When it is needed to expose the opening 213, the first driving member can drive the first reel 4 to rotate in another direction, and the second driving member can drive the second reel 5 to rotate in another direction, so that the first reel 4 and the second reel 5 wind the first hatch 22 and the second hatch 23, thereby exposing the opening 213.

[0047] The adoption of the roller shutter structure as the hatch can reduce the space occupied by the first hatch 22 and the second hatch 23, which is conducive to the miniaturization of the unmanned aerial vehicle 100. At the same time, the volume of the accommodating cavity 3 for accommodating the cargo 300 can be increased, and more cargo 300 can be loaded.

[0048] The specific type of the first driving member and the second driving member is not limited in the present disclosure, and in an embodiment provided by the present disclosure, the first driving member and the second driving member can be driving motors.

[0049] Optionally, as shown in Figure 4 The fuselage 1 is provided with a recessed cavity 11 communicating with the accommodating cavity 3, and the first reel 4, the second reel 5, the first driving member and the second driving member are all located in the recessed cavity 11. Since the recessed cavity 11 communicates with the accommodating cavity 3, the first reel 4 and the second reel 5 arranged in the recessed cavity 11 will not affect the winding or releasing of the first hatch 22 and the second hatch 23. In addition, arranging the first reel 4, the second reel 5, the first driving member and the second driving member in the recessed cavity 11 on the fuselage 1 can reduce the occupation of the volume of the accommodating cavity 3 by the first reel 4, the second reel 5, the first driving member and the second driving member, so that the accommodating cavity 3 can load more cargo 300.

[0050] Optionally, as shown in Figure 3 and Figure 6As shown, the main body 21 comprises a first plate body 211 and a second plate body 212 oppositely arranged along a first direction, the first hatch 22 and the second hatch 23 are oppositely arranged along a second direction perpendicular to the first direction, the first hatch 22 is located between the first plate body 211 and the second plate body 212 and is in sliding connection with the first plate body 211 and the second plate body 212, and the second hatch 23 is located between the first plate body 211 and the second plate body 212 and is in sliding connection with the first plate body 211 and the second plate body 212. The first plate body 211, the second plate body 212, the first hatch 22 and the second hatch 23 can jointly define the accommodating cavity 3, the gap between the bottom of the first plate body 211 and the bottom of the second plate body 212 is the opening 213, and the first hatch 22 and the second hatch 23 can cover and expose the opening 213 by sliding between the first plate body 211 and the second plate body 212, and can also support the goods 300 when the first hatch 22 and the second hatch 23 cover the opening 213.

[0051] It can be understood that part of the first hatch 22 and part of the second hatch 23 can be located between the side of the first plate body 211 and the side of the second plate body 212, so that the first hatch 22, the second hatch 23, the first plate body 211 and the second plate body 212 can enclose the accommodating cavity 3.

[0052] Optionally, as shown, Figure 6 The main body 21 further comprises a third plate body 214 and a fourth plate body 215 oppositely arranged along the second direction, and the first plate body 211, the second plate body 212, the third plate body 214 and the fourth plate body 215 enclose a box-shaped structure, and the inside of the box-shaped structure is the accommodating cavity 3. Part of the first hatch 22 is located on the inner side of the third plate body 214, and part of the second hatch 23 is located on the inner side of the fourth plate body 215, and the third plate body 214 and the fourth plate body 215 can shield and protect the first hatch 22 and the second hatch 23.

[0053] In order to make the first hatch 22 and the second hatch 23 move along the predetermined track, optionally, as shown, Figure 5 and Figure 6 The side and the bottom of the first plate body 211 are provided with a first sliding groove 2111 penetrating through, the side and the bottom of the second plate body 212 are provided with a second sliding groove 2121 penetrating through, the first hatch 22 is in sliding connection with the first sliding groove 2111 and the second sliding groove 2121 on the opposite sides along the first direction respectively, and the second hatch 23 is in sliding connection with the first sliding groove 2111 and the second sliding groove 2121 on the opposite sides along the first direction respectively.

[0054] For the embodiment that the first hatch 22 and the second hatch 23 are both the rolling shutter structure, one end of the first hatch 22 and the second hatch 23 extends into the recessed cavity 11 and is wound on the first roller shaft 4 and the second roller shaft 5, and since the side and the bottom of the first plate body 211 are provided with the first sliding groove 2111 and the side and the bottom of the second plate body 212 are provided with the second sliding groove 2121, the first hatch 22 and the second hatch 23 can be guided during the movement of the side and the bottom of the first plate body 211 and the second plate body 212.

[0055] In other embodiments, only the first sliding groove 2111 can be arranged on the bottom of the first plate body 211 and only the second sliding groove 2121 can be arranged on the bottom of the second plate body 212.

[0056] As a second aspect provided by the present disclosure, as shown in Figure 7 The present disclosure provides a cargo conveying system 200, which includes a bearing structure 201 and the unmanned aerial vehicle 100 described above, the bearing structure 201 is used for bearing a cargo 300, and the unmanned aerial vehicle 100 can perform handover of the cargo 300 with the bearing structure 201.

[0057] During the process that the unmanned aerial vehicle 100 takes the cargo 300 from the bearing structure 201, the first hatch 22 and the second hatch 23 move away from each other to expose the opening 213 through which the cargo 300 passes, and then the unmanned aerial vehicle 100 can move close to the bearing structure 201 so that the cargo 300 enters the containing cavity 3 through the opening 213. After the cargo 300 enters the containing cavity 3, the first hatch 22 and the second hatch 23 move towards each other, and at the same time of closing the opening 213, the first hatch 22 and the second hatch 23 extend between the bottom of the cargo 300 and the bearing structure 201, so as to separate the cargo 300 from the bearing structure 201, and the cargo 300 is supported by the side of the first hatch 22 and the second hatch 23 close to the containing cavity 3, so as to completely transfer the cargo 300 from the bearing structure 201 to the containing cavity 3.

[0058] During the process that the cargo is placed on the bearing structure 201 by the unmanned aerial vehicle 100 described above, the unmanned aerial vehicle 100 can move close to the bearing structure 201, and the bearing structure 201 is located below the unmanned aerial vehicle 100, the first hatch 22 and the second hatch 23 move away from each other, and at the same time of gradually exposing the opening 213, the cargo 300 can pass through the opening 213 and be received by the bearing structure 201 under the action of gravity.

[0059] The present disclosure does not limit the specific structure of the bearing structure 201, and in an embodiment provided by the present disclosure, as shown in Figure 7 and Figure 8As shown, the upper surface of the bearing structure 201 is provided with a plurality of protrusions 202, which are used to contact the bottom of the goods 300. The protrusions 202 can have a gap between the goods 300 and the upper surface of the bearing structure 201, so that one end of the first door 22 and the second door 23 is inserted into the gap to be located at the bottom of the goods 300, facilitating the first door 22 and the second door 23 to shovel the goods 300 into the accommodation cavity 3.

[0060] Optionally, the protrusions 202 can be elastic protrusions, which can elastically deform to avoid the first door 22 and the second door 23 when the first door 22 and the second door 23 move in the gap between the goods 300 and the elastic protrusions, reducing the resistance in the process of the first door 22 and the second door 23 extending into the bottom of the goods 300, so that the first door 22 and the second door 23 are more easily to transfer the goods 300 into the accommodation cavity 3.

[0061] In addition, the elastic protrusions can also act as a buffer structure to buffer the impact force of the goods 300 when the goods 300 leaves the accommodation cavity 3 through the opening 213 by its own gravity and falls onto the bearing structure 201, avoiding damage to the goods 300 and ensuring the integrity of the goods 300.

[0062] Optionally, the plurality of protrusions 202 can be arranged in a rectangular array or a circular array.

[0063] The present disclosure does not limit the specific shape of the protrusions 202, and the cross section of the protrusions 202 can be any one of a circle, a trapezoid, and a rectangle. In an embodiment provided by the present disclosure, as shown in Figure 8 The protrusions 202 can be hemispherical, which can reduce the contact area between the protrusions 202 and the goods 300, thereby increasing the gap between the goods 300 and the protrusions 202, facilitating the first door 22 and the second door 23 of the unmanned aerial vehicle 100 to extend into the gap.

[0064] Optionally, as shown in Figure 7As shown, the cargo conveying system 200 further comprises a parking structure 203 for supporting the unmanned aerial vehicle 100, the bottom of the parking structure 203 is provided with a first opening 2031, and the top of the parking structure 203 is provided with a second opening 2032, both the first opening 2031 and the second opening 2032 are configured to allow the cargo compartment 2 to pass through, and the carrying structure 201 is located below the first opening 2031.
