[0089] An embodiment of the present application provides an unmanned aerial vehicle, which may include but is not limited to any one of a manned drone, a logistics drone, an aerial photography drone, a performance drone, a combat drone, and an agricultural plant protection drone. The embodiment of the present application does not specifically limit the type of the unmanned aerial vehicle.

[0090] Referring to Figure 1, a structural schematic diagram of an unmanned aerial vehicle described in an embodiment of the present application is shown. Referring to Figure 2, a top structural schematic diagram of the unmanned aerial vehicle shown in Figure 1 is shown. Referring to Figure 3, one of the side structural schematic diagrams of the unmanned aerial vehicle shown in Figure 1 is shown. Referring to Figure 4, a second side structural schematic diagram of the unmanned aerial vehicle shown in Figure 1 is shown. Referring to Figure 5, a third side structural schematic diagram of the unmanned aerial vehicle shown in Figure 1 is shown. Referring to Figure 6, a top structural schematic diagram of the unmanned aerial vehicle shown in Figure 1 is shown.

[0091] Specifically, the unmanned aerial vehicle may include: a central body 10, a first mating portion 101 is provided on the top of the central body 10, and a second mating portion 102 is provided on the bottom of the central body 10, and the first mating portion 101 of the unmanned aerial vehicle can cooperate with the second mating portion 102 of another unmanned aerial vehicle to achieve vertical stacking of multiple unmanned aerial vehicles; a guide structure 11, the guide structure 11 is connected to the top of the central body 10, and a guide portion 111 is provided on the guide structure 11. During the landing of the unmanned aerial vehicle, the guide portion 111 of the unmanned aerial vehicle located below can limit the deviation of the unmanned aerial vehicle located above in the heading direction, so that when the two unmanned aerial vehicles are stacked up and down, the unmanned aerial vehicle located above is guided to the position where the first mating portion 101 of the unmanned aerial vehicle below and the second mating portion 102 of the unmanned aerial vehicle above cooperate with each other.

[0092] In the embodiment of the present application, since the top of the central body 10 of the UAV is provided with a first mating portion 101, and the bottom of the central body 10 is provided with a second mating portion 102, the first mating portion 101 of one UAV can cooperate with the second mating portion 102 of another UAV to achieve vertical stacking of multiple UAVs. This facilitates stacking of multiple UAVs in a smaller space, reducing the stacking space required for the UAVs. Furthermore, since the guide structure 11 is connected to the top of the central body 10 and is provided with a guide portion 111, during landing, the guide portion 111 of the UAV located below can limit the heading deviation of the UAV located above, guiding the UAV located above to a position where the first mating portion 101 and the second mating portion 102 of the UAV located below mate, thereby achieving precise landing of the UAV. This not only reduces the cost of collaborative operations of multiple UAVs, but also improves their efficiency.

[0093] Referring to FIG7 , a schematic diagram of the structure of the vertically stacked UAVs according to an embodiment of the present application is shown. As shown in FIG7 , during the landing of multiple UAVs, the second mating portion 102 at the bottom of the central body 10 of the upper UAV can cooperate with the first mating portion 101 at the top of the central body 10 of the lower UAV to reduce the stacking space of the multiple UAVs. Furthermore, the guide portion 111 of the lower UAV can limit the deviation of the upper UAV in the heading direction, thereby guiding the upper UAV to the position where the first mating portion 101 and the second mating portion 102 cooperate with each other, thereby achieving precise landing of the UAV.

[0094] In the embodiment of the present application, the guide structure 11 is connected to the first mating portion 101, so that the guide portion 111 on the guide structure 11 can be arranged close to the first mating portion 101. In this way, during the landing of the UAV, the guide portion 111 on the lower UAV can guide the second mating portion 102 of the upper UAV into the first mating portion 101 of the lower UAV, thereby achieving precise landing of the UAV.

[0095] For example, the guide structure 11 may be connected to the first matching portion 101 by welding, clamping, or other connection methods. The embodiment of the present application does not limit the specific connection method between the guide structure 11 and the first matching portion 101.

[0096] In some optional embodiments of the present application, as shown in Figure 3, the central body 10 may further include a positioning portion 112 arranged adjacent to the second mating portion 102. During the landing of the unmanned aerial vehicle, the guide portion 111 of the unmanned aerial vehicle located below can cooperate with the positioning portion 112 of the unmanned aerial vehicle located above to limit the deviation of the unmanned aerial vehicle located above in the heading direction.

[0097] In a specific application, the structure of the positioning portion 112 can be adapted to the structure of the guide portion 111, and the number of the positioning portions 112 can also be adapted to the number of the guide portions 111. In this way, during the landing process of the UAV, the guide portion 111 of the UAV located below can correspond one-to-one with the positioning portion 112 of the UAV located above, and cooperate with each other to limit the deviation of the UAV located above in the heading direction, thereby achieving a precise landing of the UAV located above.

[0098] Specifically, the structural adaptation of the positioning portion 112 and the structural adaptation of the guide portion 111 may specifically include: the positioning portion 112 has substantially the same shape and size as the guide portion 111, and can be fitted with each other. For example, the positioning portion 112 may be a protrusion protruding from the central body 10, and the guide portion 111 may be a recessed portion having substantially the same shape as the protrusion and can be fitted with the protrusion. The number of positioning portions 112 and the number of guide portions 111 may be adapted to be the same as the number of positioning portions 112 and the number of guide portions 111. For example, in the case where the number of guide portions 111 is 4, the number of positioning portions 112 may also be 4, and during the landing process of the unmanned aerial vehicle, the positioning portion 112 of the upper unmanned aerial vehicle may correspond one-to-one with the guide portion 111 of the lower unmanned aerial vehicle and cooperate with each other.

[0099] In the present application, the guide structure 11 includes multiple arms 113 and multiple propeller shields 114. One end of each arm 113 is connected to the first mating portion 101, while the other end of each arm 113 is connected to the propeller shields 114. In a specific application, the arms 113 can be used to connect and support the propellers 12, which can provide flight propulsion. The propeller shields 114 can protect the propellers 12 from impact by external objects and from injuring personnel.

[0100] In an embodiment of the present application, as shown in Figure 2, the arm 113 may specifically include a guide rib 1111, and the guide portion 111 may include two guide ribs 1111 and a groove 1112 formed by the two guide ribs 1111; the positioning portion 112 may include a protrusion adapted to the groove 1112. During the landing of the unmanned aerial vehicle, the guide rib 1111 of the unmanned aerial vehicle located below can guide the protrusion of the unmanned aerial vehicle located above into the groove 1112, so as to limit the deviation of the unmanned aerial vehicle located above in the heading direction, thereby achieving precise landing of the unmanned aerial vehicle located above.

[0101] In a specific application, during the landing process of the UAV, the UAV located above can move along the guide rib 1111 of the UAV located below until the raised portion of the UAV located above is guided into the groove 1112. Due to the limiting effect of the groove 1112 on the raised portion, the UAV will not deviate in the heading direction, thus achieving precise landing of the UAV.

[0102] Optionally, one end of the guide rib 1111 is connected to the first mating portion 101, and the other end of the guide rib 1111 at least partially extends in a direction away from the central body 10. In this way, during the landing of the unmanned aerial vehicle, even if the unmanned aerial vehicle located above initially lands at a position far away from the central body 10 of the unmanned aerial vehicle located below, since one end of the guide rib 1111 is connected to the first mating portion 101 and the other end extends in a direction away from the central body 10, under the guidance of the guide rib 1111, the unmanned aerial vehicle located above can move along the guide rib 1111 until the unmanned aerial vehicle located above is guided to the position where the first mating portion 101 and the second mating portion 102 cooperate with each other, and the raised portion of the unmanned aerial vehicle located above is guided into the groove 1112, thereby achieving precise landing of the unmanned aerial vehicle.

[0103] Optionally, the guide ribs 1111 are flexible, that is, they can be flexibly deformed. Thus, during the landing of the UAV, if the upper UAV contacts the guide ribs 1111 of the lower UAV, the guide ribs 1111 can flexibly deform to provide a cushion for the upper UAV, thereby preventing damage between the upper UAV and the lower UAV due to rigid contact, and improving the landing safety of the UAV.

[0104] Optionally, the material of the flexible part may include at least one of rubber, silicone and foam. The embodiment of the present application does not specifically limit the specific material of the flexible part.

[0105] In some optional embodiments of the present application, the first mating portion 101 may include a recessed structure that is concave toward the central body 10, and the second mating portion 102 may include a convex structure that is convex away from the central body 10. During the landing process of the UAV, the convex structure on the bottom of the upper UAV of two adjacent UAVs can be at least partially embedded in the recessed structure on the top of the lower UAV. In this way, auxiliary positioning and high-density storage of multiple UAVs can be achieved, thereby facilitating the coordinated operation of multiple UAVs.

[0106] Optionally, the groove 1112 is provided near the edge of the recessed structure, and the groove 1112 can serve as a portion of the edge of the recessed structure to increase the area of ​​the recessed structure. In this way, during the landing of the UAV, it is more convenient to guide the raised structure on the bottom of the UAV located above into the recessed structure on the top of the UAV located below, further improving the landing accuracy and efficiency of the UAV.

[0107] In some optional embodiments of the present application, the width of groove 1112 decreases gradually along the direction from the center body 10 to the propeller guard 114. That is, groove 1112 is wider on the side closest to the recessed structure, and wider at the junction of groove 1112 and the recessed structure. The effect of groove 1112 on increasing the area of ​​the recessed structure is more pronounced. This further improves the efficiency of embedding the raised structure on the bottom of the upper UAV into the recessed structure of the lower UAV during landing, further enhancing the landing accuracy and efficiency of the UAV.

[0108] In the embodiment of the present application, as shown in FIG4 , the raised portion may specifically include: a camera assembly 1121 and a barrier 1122 disposed around the camera assembly 1121, with the camera assembly 1121 at least partially embedded within the barrier 1122. In a specific application, the barrier 1122 may be used to protect the camera assembly 1121, thereby preventing the camera assembly 1121 from being impacted and improving the safety of the camera assembly 1121.

[0109] In practical applications, when the raised portion is formed by the camera assembly 1121 and the enclosure 1122 surrounding the camera assembly 1121, it is possible to avoid providing an additional raised structure on the central body 10 to form the raised portion, thereby simplifying the structure of the central body 10. Furthermore, because the camera assembly 1121 of the upper UAV can be conveniently embedded in the groove 1112 of the lower UAV, it is possible to avoid providing an additional structure on the central body 10 to avoid the camera assembly 1121, further simplifying the structure of the central body 10.

[0110] In some optional embodiments of the present application, when the protrusion is guided into the groove 1112, a gap can be formed between the camera assembly 1121 and the guide rib 1111 to avoid interference between the camera assembly 1121 and the guide rib 1111 and damage to the camera assembly 1121, thereby improving the safety of the camera assembly 1121.

[0111] In the embodiment of the present application, the unmanned aerial vehicle may further include: a propeller 12, the propeller 12 is connected to the guide structure 11, and the propeller 12 can be used to provide flight power.

[0112] Specifically, the propeller 12 can be located below the guide structure 11. By inverting the propeller 12 below the guide structure 11, the top of the arm 113 and the propeller protection cover 114 can form a concave structure, further enhancing the guidance of the UAV above, thereby further improving the landing accuracy of the UAV. Moreover, during the landing of the UAV, since the propeller 12 is located below the guide structure 11, the UAV above can be prevented from colliding with the propeller 12 of the UAV below, thereby improving the landing safety of the UAV.

[0113] Optionally, the propeller 12 can be located below the arm 113. By placing the propeller 12 upside down below the arm 11, the top of the arm 113 and the propeller shield 114 form a recessed structure, further enhancing the guidance of the UAV above, thereby further improving the landing accuracy of the UAV. Furthermore, during the landing of the UAV, since the propeller 12 is located below the arm 113, the UAV above can be prevented from colliding with the propeller 12 of the UAV below, thereby improving the landing safety of the UAV.

[0114] Optionally, the guide structure 11 may further include a plurality of propeller guards 114, which are connected to the end of the arm 113 away from the first mating portion 101. In a specific application, by incorporating the propeller guards 114 into a portion of the guide structure 11, the overall area of ​​the guide structure 11 can be increased, thereby improving the guidance range of the guide structure 11 and further enhancing the landing accuracy of the UAV.

[0115] In this embodiment of the present application, the UAV may further include an antenna assembly 13, which is located within a propeller shield 114. Because the propeller shield 114 is located away from the hub 10 and the area blocked by it is relatively small, the placement of the antenna assembly 13 within the propeller shield 114 reduces interference from other electronic components on the hub 10 and reduces the area blocked by the antenna assembly 13, thereby facilitating radiation from the antenna assembly 13. This improves the performance of the antenna assembly 13.
