[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0033] Please refer to Figure 1-9 As shown, an embodiment of the present application provides a UAV mounting device, including a mounting component 1 and an adapter assembly for connecting a load device, the mounting component 1 is provided with a first connection portion 11 for connecting the UAV and a second connection portion 13 connected to the adapter assembly, the second connection portion 13 includes a plurality of first connection positions arranged at the bottom of the mounting component 1 along the heading direction, the adapter assembly is connected to one or more of the plurality of first connection positions; the adapter assembly is provided with a threading channel, a wiring harness channel 12 is provided in the mounting component 1, the wiring harness channel 12 passes through each first connection position of the second connection portion 13, so as to be connected to the threading channel of the adapter assembly on the first connection position.

[0034] Among them, the mounting component 1 is used to be installed on the drone, which can be installed on the bottom of the drone body or on the lower surface of the wing of the drone, and is specifically connected to the drone through the first connecting part 11. The adapter assembly is used to connect the load equipment, and the load equipment can be mounted by connecting it to the adapter assembly. The second connecting part 13 of the mounting component 1 is provided with a plurality of first connecting positions, each connection position or a plurality of connection positions cooperates to install an adapter assembly, and the load equipment is then connected through the adapter assembly, so that a single or multiple load equipment can be mounted according to demand, and the position of the installed load equipment can be adjusted in the heading direction through the plurality of first connecting positions, which is convenient and practical. The adapter assembly is provided with a threading channel, which can facilitate the transmission harness or control harness of the load equipment to pass through the threading channel and the harness channel 12 to connect with the drone system, which can facilitate data transmission and control, and can also achieve the hiding of the harness, which is more indirect and practical. At the same time, each first connection position is penetrated by the harness channel 12, which can facilitate the wiring of the harnesses of the load equipment connected at different positions to be hidden, which not only reduces wind resistance but also improves the overall aesthetics. Specifically, the first connecting part 11 can be a T-shaped connecting member 112, and the two ends of its upper end can be provided with wing mounting holes 111, and the mounting holes can be connected to the wings of the drone through fasteners.

[0035] Through the above-mentioned technical solution, a mounting component 1 having a plurality of second connection positions 31 is provided, which cooperates with an adapter assembly to realize mounting a plurality of load devices or adjusting the mounting position of the mounting device, which is more convenient and practical, and through the cooperation of the wiring harness channel 12 and the threading channel of the adapter assembly, the wiring harness can be hidden when the load device is mounted at different positions or multiple devices, and the wiring design is more reasonable and convenient.

[0036] In an embodiment of the present application, the adapter assembly may include an adapter 2, through which a load device is connected. Of course, multiple loads can also be connected after adapter in conjunction with a parallel component 3. The specific combination can be selected according to actual needs.

[0037] In one application scenario, in order to achieve the mounting and installation of a small amount of load equipment, an adapter 2 can be used to connect a first connection position or multiple first connection positions are respectively connected to an adapter 2. In this application scenario, an adapter assembly of a structure may include an adapter 2 of a cylindrical structure, and both ends of the adapter 2 are provided with a third connection part 22 for connecting to the first connection position and a fourth connection part 21 for connecting to the load equipment.

[0038] In this embodiment, the adapter 2 is used as an adapter assembly to connect the load device, that is, the mounting member 1 is connected to one load device through the adapter 2. Such a connection structure is used when only one load device needs to be installed. The adapter 2 is a cylindrical structure, and a channel can be formed inside it, which is used as a threading channel for wiring. The adapter 2 can be connected to the first connection position through the third connection part 22 at the top, and the fourth connection part 21 at the bottom is used to connect to the load device.

[0039] On this basis, in order to facilitate the installation of the adapter 2 on the mounting member 1, the first connection position includes a first installation position 133 provided at the bottom of the mounting member 1, and the third connection portion 22 includes an adapter plate 211 provided at the end of the adapter 2, and the adapter plate 211 is detachably connected to the first installation position 133. By using the bottom of the mounting member 1 as the first installation position 133, it is convenient to set the second installation position 134, and it is also convenient to install a single load device, which can reduce the resistance in the heading direction and make the center of gravity of the load device and the center of gravity of the hanging member in the same longitudinal direction, so that its structure and stability are better.

[0040] Specifically, the adapter plate 211 is provided with a plurality of first holes, and the bottom of the mounting component 1 is provided with a plurality of second holes. The first holes are connected to the second holes by fasteners, and the first holes and the second holes adopt a uniform hole structure, so as to facilitate detachable connection or replacement and installation with other accessories. A circumferential connecting edge is provided at the bottom end of the fourth connecting portion 21, and a uniform hole structure is provided on the circumferential connecting edge. A matching connecting structure is also provided on the load device, so as to facilitate the detachable installation of the load device. In addition, since the load devices may be different and their connection parts are also different, the fourth connecting portion 21 can be customized and adapted by changing the shape or diameter of the circumferential connecting edge.

[0041] In another application scenario, in order to achieve the mounting and installation of more load equipment, the adapter 2 can be used in conjunction with the parallel member 3 to connect a first connection position or multiple first connection positions are respectively connected to an adapter assembly. In this application scenario, a structural adapter assembly includes a parallel member 3 and a cylindrical structure adapter 2, the parallel member 3 is connected to the first connection position of the mounting member 1, the parallel member 3 is provided with multiple second connection positions 31, each second connection position 31 is respectively connected to an adapter 2 to connect multiple load equipment; the parallel member 3 is provided with a threading cavity, the threading cavity and the inner cavity of the adapter 2 constitute the wiring harness channel 12.

[0042] This embodiment is used to connect multiple load devices to a single first connection position. In addition to the adapter 2, it is also necessary to cooperate with the parallel component 3 for installation. The parallel component 3 used is provided with multiple second connection positions 31. Each second connection position 31 can be installed with an adapter 2, and a load device is connected through the adapter 2. In this way, the need to install multiple load devices in one first connection position can be met, making the installation more flexible and practical. The parallel component 3 is also provided with a threading cavity, which can facilitate the passage of the wire harness of the load device passing through the adapter 2, and then can facilitate the connection with the drone system through the wire harness channel 12 of the mounting component 1, realizing the hidden wiring of the wire harness.

[0043] On this basis, in order to facilitate stable and reliable installation of the parallel member 3, the first connection position includes a second installation gear position 134, and the second installation gear position 134 includes a group of connectors 131 or multiple groups of connectors 131 arranged along the heading direction, and each group of connectors 131 includes connectors 131 arranged in pairs on both sides of the mounting member 1. The pairs of connectors 131 arranged on both sides of the mounting member 1 can be used as a second installation gear position 134 for connecting the parallel member 3, so that it has connection points with a large spacing perpendicular to the heading direction, so that it can be more stable and reliable when carrying multiple load devices.

[0044] Preferably, the connector 131 is an L-shaped connector 131, one end of which is fixed to the side of the mounting member 1, and the other end is provided with a uniform gear connection hole 132, which can be connected to the adapter 2 or the parallel member 3 of the adapter assembly through a standard fastener, making installation more convenient. It should be noted that the first installation gear 133 and the second installation gear 134 may not be set at the same time, but are set at the same time in a preferred embodiment.

[0045] The detachable connection method can facilitate modularization and interchangeable parts. If the mission payload equipment has a new installation interface, only the adapter block needs to be adaptively changed without the need to newly develop the entire bracket.

[0046] Furthermore, the parallel member 3 extends along a first direction perpendicular to the heading, and the second connecting position 31 is arranged on the parallel member 3 along the first direction.

[0047] In this way, the extension direction of the parallel component 3 is perpendicular to the heading, which can facilitate the operation of the load-bearing equipment, and through such an arrangement, the load-bearing equipment can be better mounted in a balanced manner.

[0048] Furthermore, in order to meet the working requirements of some load equipment, such as the need to stay away from the large drone body to avoid flow interference during operation, at least one adapter 2 among the multiple adapters 2 connected to the second connection position 31 on the parallel member 3 is configured to have a height greater than the height of the remaining adapters 2. By designing the adapter 2 used to install the load equipment with the requirement of "needing to stay away from the large drone body to avoid flow interference during operation" to a larger height, the load equipment can be kept away from the main body of the drone, thereby avoiding flow interference from the drone body. At the same time, the mounting position of the load equipment in the height direction can be adjusted through the adapter 2 with a higher height, so that the load equipment can be adjusted in both the heading direction and the height direction.

[0049] In order to reduce the wind resistance effect of the mounting component 1 on the flight of the UAV, the mounting component 1 is provided with an airflow straightening structure 17 at the front and / or rear end in the heading direction. The airflow straightening structure 17 may be a V-shaped or U-shaped straightening structure, or other existing straightening structures.

[0050] Specifically, the airflow rectifying structure 17 disposed at the front end of the mounting component 1 is a V-shaped rectifying structure 171, and the airflow rectifying structure 17 disposed at the rear end of the mounting component 1 is a U-shaped rectifying structure 172, which can also be called an arc rectifying structure. Such a rectifying structure design can be more conducive to reducing the wind resistance caused by the mounting component 1 to the drone. In addition, the mounting component 1 as a whole also adopts a flat and long structure extending along the heading direction, and its width is very small, and such a structure can reduce wind resistance to a greater extent.

[0051] In the embodiment of the present application, a first electrical connector 15 is provided in the wiring harness channel 12 , a second electrical connector 23 is provided in the adapter 2 , and the first electrical connector 15 is connected to the second electrical connector via a wire harness 16 .

[0052] The first electrical connector 15 provided in the entrance of the harness channel 12 is used for the transfer of the harness, which can facilitate the connection of the harness. Similarly, the second electrical connector 23 provided in the inner cavity of the adapter 2 can be conveniently connected to the load equipment, which can effectively improve the installation efficiency of the load. The second electrical connector 23 integrated in the adapter 2 is connected to the first electrical connector 15 in the mounting component 1 through the harness inside the mounting component 1, which usually includes power supply lines, RS422, 485 and other communication harnesses. Harnesses and customized electrical connectors can be added according to the mission load requirements.

[0053] In the specific implementation process, the mounting component 1 is provided with a plurality of maintenance windows connected to the harness channel 12 along the route direction, and the maintenance windows are provided with maintenance cover 14. By providing the maintenance windows, it is convenient to thread and route the harness in the harness channel 12 and to inspect and repair it, which is more convenient for maintenance operations.

[0054] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
