The receiving structure 11 has access to the basket 2 above it. For example, the upper side of the receiving structure 11 is open, so that the basket 2 can be taken out or put in from above the receiving structure 11. Alternatively, the accommodating structure 11 may have another structure such as an openable door above it. In the schematic of fig. 1A and 1B, the drone 1 comprises 8 cantilevers 12. A first end of the cantilever 12 is connected to the accommodating structure 11, and a second end of the cantilever, which is far away from the accommodating structure 11, is mounted with a motor (e.g., a dc brushless motor). The motor is provided with a propeller.

The drone 1 may also comprise at least two power batteries 201. In the schematic of fig. 1A and 1B, on the other side from the power cell 201 visible in the figures, there is also mounted another power cell 201. The at least two power batteries 201 are respectively mounted on one of the at least two corresponding power battery carrying structures 20. Wherein the at least two power cell carrying structures 20 may be seen in the description below with respect to fig. 7A and 7B. According to an embodiment of the present disclosure, the at least two power battery carrying structures 20 are symmetrically disposed at the periphery of the accommodating structure 11 with respect to a vertical line passing through the center of gravity of the body 10 (see fig. 1C). The at least two power cells 201 are fixed in the fuselage body 10 by the at least two power cell carrying structures 20, and such that the at least two power cells 201 are symmetrical with respect to a vertical line passing through the center of gravity of said fuselage body 10.

The drone 1 may also comprise positioning means 301. The positioning device 301 may be, for example, a GPS or an RTK (Real-Time Kinematic) related device. According to an embodiment of the present disclosure, the positioning device 301 is mounted in a positioning device mounting structure 30 (refer to the description of fig. 9 below). The positioning device mounting structure 30 may be disposed at an edge of the accommodating structure 11, so that the positioning device 301 is fixed at the edge of the accommodating structure 11. In the illustration of fig. 1A and 1B, the drone 1 comprises two positioning devices 301. The connecting line of the two positioning devices 301 is parallel to the connecting line of the head and the tail of the unmanned aerial vehicle 1. According to the embodiment of the present disclosure, two positioning devices 301 are disposed at the edge of the accommodating structure 11, and the positioning devices 301 can be prevented from being hit when loading and unloading the cargo basket 2 from above the unmanned aerial vehicle 1.

The drone 1 may also include an avionics system. The avionics system may be installed inside an avionics bay 40. The avionics pod 40 may be of an integrated sealed design. According to an embodiment of the present disclosure, the avionics bay 40 may be provided at the bottom of the housing structure 11 on a vertical line passing through the center of gravity of the fuselage body 10, so that the flight control may be mounted on the vertical line of the center of gravity of the fuselage body 10.

Fig. 1A and 1B show the structural form of the unmanned aerial vehicle 1, which avoids concentrating the control system and the fixed end of the cantilever 12 in the middle of the body of the unmanned aerial vehicle 1, so that there is a large space in the middle of the body of the unmanned aerial vehicle 1 for installing a cargo basket. Holding structure 11 includes the downwardly recessed accommodation space, and the basket is placed in holding structure 11, and basic and unmanned aerial vehicle 1's the focus position coincidence for unmanned aerial vehicle 1 can not have obvious change in the focus position when full-load and empty load. Specifically, when the unmanned aerial vehicle 1 is not loaded into a basket, the center of gravity of the unmanned aerial vehicle 1 is located below the geometric center of the unmanned aerial vehicle 1. When unmanned aerial vehicle 1 packed into the basket, unmanned aerial vehicle 1's focus was also in some positions of unmanned aerial vehicle 1's geometric centre under again, therefore unmanned aerial vehicle 1's focus position is unchangeable basically.

Fig. 1C schematically shows a perspective structure diagram of the unmanned aerial vehicle 1 according to an embodiment of the present disclosure, and fig. 1D schematically shows a top view of the unmanned aerial vehicle 1 according to an embodiment of the present disclosure.

As shown in fig. 1C and 1D, from a structural division perspective, the unmanned aerial vehicle 1 includes a housing structure 11 and at least one suspension arm 12 (8 suspension arms 12 in the specific example in the figure). Wherein the receiving structure 11 comprises a bottom supporting frame 111 and a circumferential supporting frame 112. The bottom support frame 111 is connected below the circumferential support frame 112. The bottom support frame 111 may on the one hand serve as a bottom of the receiving structure 11 for carrying a basket; on the other hand, the circumferential support frame 12 can be connected and stabilized, and the structural stability of the fuselage body 10 is enhanced. A first end of each cantilever 12 of the at least one cantilever 12 is connected to the receiving structure 11, and a second end opposite to the first end extends away from the receiving structure 11.

From another structural division perspective, the fuselage body 10 of the drone 1 may include at least three arms 14 (specifically, four arms 14 are illustrated in the figure). The four arms 14 are connected in a pairwise staggered manner, and two ends of each arm 14 of the four arms 14 extend out of a staggered area 15, wherein the staggered area 15 is an area formed by the four arms 14 in a pairwise staggered manner. Wherein the portions of the four arms 14 located within the staggered area 15 constitute the circumferential support frame 112. The portions of the four arms 14 outside the crossover region 15 constitute the at least one boom 12 (so 8 booms 12 are obtained). The bottom support frame 111 is located in the space of the staggered area 15 and connected to the lower side of the circumferential support frame 112. The connection and combination of the bottom support frame 111 and the circumferential support frame 112 forms the containment structure 11.

As shown in fig. 1C and 1D, the main body 10 of the drone 1 includes four arms 14 staggered two by two, forming a "groined" fuselage frame. The receiving structure 11 may be disposed in the middle of the frame of the fuselage shaped like a Chinese character jing.

According to an embodiment of the present disclosure, each horn 14 of the drone 1 may be folded, for which reference may be made to the illustrations of fig. 2A-2C.

Fig. 2A schematically illustrates a schematic view of the "groined" frame of the drone 1 with the horn 14 in a deployed state, according to an embodiment of the present disclosure; fig. 2B schematically shows a schematic view of the folding process of the horn 14 in the "groined" frame of the drone 1 according to an embodiment of the present disclosure. Fig. 2C schematically illustrates a schematic view of the folded boom 14 in the "cross-shaped" fuselage frame of the drone 1 according to an embodiment of the present disclosure.

As shown in fig. 2A to 2C, when the unmanned aerial vehicle 1 is stored, the two cantilevers 12 in each arm 14 may be folded toward the intersection area 15 to reduce the space of the unmanned aerial vehicle 1.

As particularly shown in fig. 2A, according to an embodiment of the present disclosure, each horn 14 may include a first body 141, two second bodies 142, and two connectors 143. The two connecting members 143 are respectively disposed at two ends of the first body 141. Wherein the first body 141 and each of the two second bodies 142 are foldably connected by one of the two connecting members 143. The first body 141 forms part of said each horn 14 belonging to said circumferential support frame 112, and the two second bodies 142 form part of said each horn 14 belonging to said at least one boom 12. For example, each second body 142 may form a cantilever 12 as shown in the figures.

Fig. 3A schematically illustrates a folded plan view of the horn 14 taken from perspective a in fig. 2C, in accordance with an embodiment of the present disclosure. Fig. 3B schematically shows a perspective view of the arm 14 of the drone 1 in fig. 3A in a deployed state.

As shown in fig. 3A and 3B, according to an embodiment of the present disclosure, a minimum distance of two second bodies 142 (i.e., two second bodies 142 respectively connected to both ends of the same first body 141) in the same horn 14 in a direction perpendicular to a plane of a fuselage formed by the at least three horns 14 being staggered two by two is greater than zero. In this way, when the four arms 14 are assembled to form the shaft-shaped body frame of the unmanned aerial vehicle 1, the two adjacent second bodies 142 can be at different heights, and the minimum distance between the two adjacent second bodies 142 (i.e., the two second bodies 142 folded toward each other) in the direction perpendicular to the plane of the body can be greater than zero by the installation and combination (as shown in fig. 3B). In this way, when two adjacent second bodies 142 are folded relatively, the two adjacent second bodies can be not interfered with each other, and the problem existing when the horn is folded transversely relatively in the prior art is avoided.

Fig. 3C schematically shows a perspective view of the connecting member 143 shown in part C of fig. 3B. Fig. 3D schematically shows a perspective view of the connecting member 143 shown in part D of fig. 3B.

As shown in fig. 3C and 3D, the connecting member 143 may include a first frame structure 1410, and a second frame structure 1420. The first frame structure 1410 includes a first gripping member 1411 and a first opening 1412. The second frame structure 1420 is connected to the first frame structure 1410. The second frame structure 1420 includes a second clamp member 1421 and a second opening 1422, the second opening 1422 being oriented differently than the first opening 1412. Wherein the first frame structure 1410 places an end of one first body 141 through the first opening 1412, and the second frame structure 1420 places an end of another first body 141 through the second opening 1422. Wherein the first opening 1412 and the second opening 1422 are oriented in the same direction (e.g., perpendicular) as the two arms 14 that are staggered with each other.

At least one of the first and

second clamp members

1411 and 1421 is rotatably coupled to at least one second body 142. For example, two horn members 14 are staggered with each other at staggered positions, one second body 142 is foldably connected to the first clamping part 1411, and the other second body 142 is foldably connected to the second clamping part 1421 (see a partially enlarged view of part c or part d in fig. 3B).

Fig. 3C and 3D are different in that the first clamping part 1411 and the first opening 1412 of the connecting member 143 in fig. 3C are adjacent to each other, and the second clamping part 1421 and the second opening 1422 are adjacent to each other. In fig. 3D, the first clamping part 1411 and the first opening 1412 of the connecting member 143 are opposite to each other, and the second clamping part 1421 and the second opening 1422 are opposite to each other.

As shown in fig. 3C in particular, according to one embodiment of the present disclosure, the first clamping member 1411 and the first opening 1412 are adjacent to each other, the second clamping member 1421 and the second opening 1422 are adjacent to each other, such that when the second body 142 (i.e., the cantilever 12) is unfolded, the second body 142 connected to the first clamping member 1411 is perpendicular to one first body 141 disposed in the first frame structure 1410 through the first opening 1412, and the second body 142 connected to the second clamping member 1421 is perpendicular to the other first body 141 disposed in the second frame structure 1420 through the second opening 1422. The first body 141 and the second body 142 of one horn 14 connected by the connecting member 143 in fig. 3C are at different heights (see part C in fig. 3B).

As shown in fig. 3D, according to another embodiment of the present disclosure, the first clamping member 1411 and the first opening 1412 are opposite to each other, and the second clamping member 1421 and the second opening 1422 are opposite to each other. Thus, such that when the second body 142 (i.e., boom 12) is unfolded, the second body 142 connected to the first clamping member 1411 and one of the first bodies 141 disposed in the first frame structure 1410 through the first opening 1412 are parallel to each other (e.g., in opposite directions), and the second body 142 connected to the second clamping member 1421 and the other of the first bodies 141 disposed in the second frame structure 1420 through the second opening 1422 are parallel to each other (e.g., in opposite directions). The first body 141 and the second body 142 of one horn 14 connected by the connecting member 143 in fig. 3D are at the same height (see part D in fig. 3B).

Fig. 4A schematically illustrates a folded view of the horn 14 from perspective a in fig. 2C, according to another embodiment of the present disclosure.

As shown in fig. 4A, according to another embodiment of the present disclosure, the connection member 143 may include a rotation axis at an acute angle with respect to a first plane perpendicular to a direction pointing from the connection member 143 to the first body 141, and each of the second bodies 142 may be rotatably folded about the rotation axis with respect to the first body 141. Therefore, when the directions of the rotation axes of the two connecting members 143 connected to the two adjacent second bodies 142 are parallel and the included angle with the first plane is properly selected, the two adjacent second bodies 142 can rotate in the planes which are parallel and separated from each other by a certain gap when folded relatively, and in this way, the interference problem when the two adjacent second bodies 142 are folded relatively can be avoided.

Fig. 4B schematically shows an enlarged view of the connecting member 143 of fig. 4A with the first body 141 and the second body 142 of the horn 14 in a folded state; fig. 4C schematically shows a perspective view of the connecting member 143 in fig. 4A and 4B.

As shown in fig. 4B and 4C, according to an embodiment of the present disclosure, the connection member 143 may include a fixed part 1431 and at least one movable part 1432. The fixed part 1431 is connected with the first body 141, and each movable part 1432 is connected with one of the at least one second body 142.

The bottom support frame 111 further comprises a limiting frame 1123 connected to at least the at least two first beams 1121; wherein the spacing frame 1123 is higher than the bottom of the bottom support frame (20). The limiting frame 23 is used for limiting and stabilizing goods (for example, a basket matched with the limiting frame 23) placed in the accommodating structure 111. The limiting frame 23 is connected to at least each of the at least two first beams 1121 through a connecting plate. The position relationship between the position limiting frame 1123 and the first beam 1121 and/or the second beam 1122 can be adjusted by connecting the connecting plates.

According to the disclosed embodiment, the accommodating structure 11 may be a rectangular frame, for example, the length of the accommodating structure 11 in the direction of the line connecting the head and the tail of the unmanned aerial vehicle 1 is greater than the length in the direction perpendicular to the line connecting the head and the tail of the unmanned aerial vehicle 1. Thus, the bottom support frame 111 may form a mechanism that is elongated in the fore-aft direction, thereby reducing drag.

It should be noted that, in the example of fig. 2A and 2B, the extending direction (i.e., the first direction) of the first beam 1121 is perpendicular to the second beam 1122 (i.e., the second direction) is merely an example. In practical applications, the first direction and the second direction may have other included angles. For example, the second beam 1122 may be a cross beam and connected to the first beam 1121.
