[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] To improve the heat dissipation of the main control module of a drone, this utility model provides a novel heat dissipation structure. Specifically, the structure utilizes the body portion at the location where the main control module is installed for heat dissipation, and also sets up a corresponding heat-conducting layer to enhance the heat conduction effect and improve the heat exchange efficiency.

[0051] See Figure 1 The present invention illustrates the principle of the heat dissipation structure of the main control module of a drone. The drone 1 may include a body 11, the body 11 including a hollow and thermally conductive front crossbeam 111, and a first cooling air duct 1111 provided on the front crossbeam 111. The first cooling air duct 1111 has an air inlet 1112 that matches the windward direction of the body 11's movement, and correspondingly, air can enter the first cooling air duct 1111 through the air inlet 1112. Here, the first cooling air duct 1111 may be a hollow channel of the front crossbeam 111, or it may be another channel connected to the hollow channel.

[0052] The front crossbeam 111 is equipped with a main control module 12 having a heat-conducting base shell 121, and a heat-conducting layer 13 is also provided between the heat-conducting base shell 121 and the front crossbeam 111. The heat generated by the main control module 12 is conducted to the front crossbeam 111 through the heat-conducting layer 13, significantly increasing the heat dissipation area and improving the heat dissipation efficiency. Furthermore, the air entering the first cooling air duct 1111 through the air inlet 1112 can carry away some of the heat on the front crossbeam 111, thereby achieving further heat dissipation and cooling of the main control module 12, resulting in better heat dissipation effect.

[0053] It is understood that the front crossbeam 111 can be a metal tube or alloy tube with good thermal conductivity, and the thermal conductive layer 13 can be a thermally conductive pad such as a thermally conductive silicone pad.

[0054] See Figures 2 to 6 In the UAV 2 provided in this embodiment, the body 21 includes a hollow and thermally conductive front crossbeam 211. A first cooling air duct 2111 is provided on the front crossbeam 211. The first cooling air duct 2111 has a windward opening that matches the windward direction of the body 21's movement, that is... Figure 2 The first through hole 2112 is provided. In addition, the front crossbeam 211 is provided with a main control module 22 having a heat-conducting bottom shell 222, and a heat-conducting layer (not shown) is also provided between the heat-conducting bottom shell 222 and the front crossbeam 211.

[0055] like Figure 2 and Figure 3 As shown, a plurality of main control brackets 23 are provided on the front crossbeam 211. The main control bracket 23 includes a first connecting plate 231 disposed on the horizontal surface of the top side of the front crossbeam 211, and an extension plate 232 extending from the first connecting plate 231 in the horizontal direction out of the front crossbeam 211. The extension direction of the extension plate 232 is perpendicular to the extension direction of the tube of the front crossbeam 211, thereby providing sufficient support surface for the heat-conducting bottom shell 222 as much as possible, so as to ensure that the main control module 22 can be stably disposed on the front crossbeam 211.

[0056] Furthermore, the main control bracket 23 may also include a second connecting plate 233 disposed on the front surface of the front crossbeam 211, and / or a third connecting plate 234 disposed on the rear surface of the front crossbeam 211. The second connecting plate 233 is perpendicular to the first connecting plate 231, and the third connecting plate 234 is perpendicular to the first connecting plate 231. Therefore, the main control bracket 23 can form connections with three different surfaces of the front crossbeam 211, further ensuring that the main control module 22 can be stably disposed on the front crossbeam 211. In addition, two main control brackets 23 are provided on the front crossbeam 211, and the two main control brackets 23 together provide support for the main control module 22. In order to form a more stable fixed connection between the first connecting plate 231 and the second connecting plate 233, a reinforcing plate 235 is also provided between the vertical angles formed by the first connecting plate 231 and the second connecting plate 233. The reinforcing plate 235 is also connected to the extension plate 232.

[0057] Understandably, the main control bracket 23 also allows a gap to be formed between the heat-conducting base shell 222 and the front crossbeam 211, within which a heat-conducting layer can be installed, thus avoiding additional costs associated with modifying the structure of the heat-conducting base shell 222 or the front crossbeam 211. Preferably, the main control bracket 23 adopts an integrally molded structure to ensure that it provides sufficiently stable support for the main control module 22.

[0058] A mounting bracket 24 with a second cooling air duct 241 is also provided on the front crossbeam 211. The mounting bracket 24 is located between the two main control brackets 23. The first cooling air duct 2111 includes a first through hole 2112 (corresponding to the aforementioned air inlet) disposed on the front surface of the front crossbeam 211. The first through hole 2112 communicates with the hollow cavity of the front crossbeam 211, and the first cooling air duct 2111 communicates with the second cooling air duct 241. Therefore, air can flow into the first cooling air duct 2111 through the second cooling air duct 241 and carry away the heat on the front crossbeam 211 to the outside.

[0059] Furthermore, the mounting bracket 24 is located on the front surface of the front crossbeam 211. A third cooling air duct 242 is also provided on the mounting bracket 24. The height of the third cooling air duct 242 is higher than that of the second cooling air duct 241. A first air supply assembly (not shown) is provided on the first cooling air duct 2111 and / or the second cooling air duct 241, which can accelerate the air circulation speed, help improve the heat exchange speed, and improve the heat dissipation efficiency.

[0060] In addition, a second air supply assembly (not shown in the figure) may be provided on the third cooling air duct 242. The main control module 22 is located at the blowing port of the second air supply assembly. Therefore, air can also directly act on the main control module 22 to directly cool the main control module 22, thereby helping the main control module 22 to work normally within the allowable temperature range and thus ensuring flight stability.

[0061] In this embodiment, the mounting bracket 24 may further include a fourth connecting plate 243 and a fifth connecting plate 245. The fourth connecting plate 243 is connected to the front surface of the front crossbeam 211, and the fifth connecting plate 245 is connected to the bottom surface of the front crossbeam 211, so that the mounting bracket 24 and the front crossbeam 211 can be stably connected.

[0062] Furthermore, the fourth connecting plate 243 has a second through hole 244 corresponding to the position of the first through hole 2112. The first through hole 2112 and the second through hole 244 are connected, thereby enabling the first cooling air duct 2111 and the second cooling air duct 241 to be connected.

[0063] In one embodiment, the mounting bracket 24 further includes an assembly bracket 246 disposed on the fourth connecting plate 243 and the fifth connecting plate 245. The assembly bracket 246 forms an assembly groove 2461 communicating with the second through hole 244. A lidar device (not shown) can be assembled in the assembly groove 2461. Therefore, the interconnected first cooling air duct 2111 and second cooling air duct 241 can also provide air cooling for the lidar device.

[0064] like Figure 2 As shown, the main control module 22 may further include a main control body 221 and an upper cover 223 covering the main control body 221. The upper surface of the upper cover 223 may be provided with multiple wiring terminals 224. Preferably, the multiple wiring terminals 224 are arranged in a staggered manner on the upper cover 223 to optimize the use of the limited surface area of ​​the upper cover 223. Furthermore, multiple wire-holding grooves 225 are provided on the periphery of the heat-conducting base shell 222 to support the stabilization of each wiring harness.

[0065] like Figure 6 As shown, the body 21 also includes a hollow rear crossbeam 212 and a connecting beam 213. The two ends of the connecting beam 213 are respectively connected to the front crossbeam 211 and the rear crossbeam 212. The front crossbeam 211, the rear crossbeam 212 and the connecting beam 213 are connected, so that the air in the first cooling air duct 2111 can also carry away the air in other beams.

[0066] Furthermore, the UAV body 21 provided by this utility model also includes an arm connector 214. The arm connector 214 has a first socket (not shown), a second socket (not shown), and a third socket (not shown) for inserting and fixing the arm (not shown), the front crossbeam 211, and the connecting beam 213, respectively. The first socket, the second socket, and the third socket are connected, thereby enabling the arm to communicate with the connected beam. Therefore, the air in the first cooling duct 2111 can also flow out to the outside through the arm and dissipate heat from the electrical modules on the arm.

[0067] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this utility model.
