[0001] This utility model relates to the field of aerospace technology, and in particular to a data link mounting bracket and a data link relay station. Background Technology

[0002] Unmanned aerial vehicles (UAVs) require stable data transmission during flight to enable functions such as remote control and image transmission. Data link brackets are used to mount the UAV's data link antenna and other equipment, ensuring the antenna maintains a good attitude during flight for stable data communication.

[0003] Commonly used data link devices for drones include antennas and RTK receivers, with sizes ranging from 3cm×5cm to 10cm×15cm. High-frequency vibrations and high-speed wind resistance during drone flight can cause incompatible brackets to loosen, or even cause data link devices to fall off.

[0004] The diverse specifications of existing data link products lead to different installation space requirements. Traditional brackets are mostly designed in a single form, making it difficult to reserve space for compatibility, resulting in poor compatibility. Utility Model Content

[0005] Based on the above analysis, the present invention aims to provide a data link mounting bracket and a data link relay station to solve the problem of poor compatibility of traditional data link mounting brackets used for UAVs.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] One aspect of this utility model is to provide a data link mounting bracket, including a support portion and a first device connection portion;

[0008] The support portion is disposed at the bottom of the mounting bracket; the first device connection portion is disposed on the first side of the support portion and is used to fix the data link device.

[0009] The first device connection part includes a bending structure at the top, the bending structure being provided with antenna fixing holes of various apertures and spacings, the antenna fixing holes being used to fix the omnidirectional antenna of the data link device.

[0010] Furthermore, the antenna mounting hole is used to mount an omnidirectional antenna of a data link device with an antenna interface less than 55mm.

[0011] Furthermore, the first device connection part also includes a first device connection part body; the first device connection part body is provided with connection holes of various apertures and spacings, the connection holes being used to connect data link devices of different dimensions.

[0012] Furthermore, the bending structure consists of two flanges with a notch between them.

[0013] Furthermore, it also includes a second device connection part, which is used to install a second device; the second device connection part is provided with a plurality of elongated through holes along its height direction; the elongated through hole in the middle of the second device connection part can be used to position the second device of different dimensions by bolts with different spacing, and the elongated through holes on both sides of the elongated through hole in the middle part are used to fix the second device.

[0014] Furthermore, the bracket has a U-shaped structure; the second device connection part is disposed on the second side of the support part, and the first side and the second side are disposed opposite to each other.

[0015] Furthermore, the first device connection part body is provided with a hollowed-out part, and the connection hole is provided in the area of ​​the first device connection part body other than the hollowed-out part.

[0016] Furthermore, the hollowed-out portion includes a first hollowed-out portion and a second hollowed-out portion, with the first hollowed-out portion located above the second hollowed-out portion, and both the first hollowed-out portion and the second hollowed-out portion having a square through-hole structure.

[0017] Furthermore, the support has a mounting hole at its center, which is used to connect to the fuselage of the drone or the tripod of the drone.

[0018] Another aspect of this utility model is to provide a data link relay station, including the aforementioned data link mounting bracket.

[0019] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0020] (1) The mounting bracket of this utility model is provided with a support part and a first device connection part. The support part is located at the bottom and is used to support the entire bracket. The top of the first device connection part has a bending structure, and the bending structure is provided with antenna fixing holes of different shapes and sizes. When installing data link equipment with antenna interface spacing of less than 55mm, since its own antenna interface does not meet the requirement of antenna spacing greater than 55mm, the radio frequency interface of the small data link equipment is usually fixed in the antenna fixing holes of the mounting bracket to obtain the optimal omnidirectional antenna spacing. A cable is led out from the antenna interface to connect the radio frequency interface and the omnidirectional antenna, thereby improving the compatibility of different data link equipment installations and ensuring that the antenna maintains a good attitude during flight to achieve stable data communication.

[0021] (2) The main body of the first device connection part is provided with connection holes of various diameters and spacings to adapt to data link devices of different dimensions, so as to ensure compatibility with different data link devices. Each type of connection hole is set at a different spacing in the corresponding position to match the spacing of the mounting holes of different data link devices.

[0022] (3) To facilitate the installation of the omnidirectional antenna, the bending structure is set with two flanges; a notch is provided between the flanges for the cable to pass through.

[0023] (4) The elongated through-hole of the second equipment connection part is set along the height direction of the second equipment connection part. While reducing weight, the elongated through-hole in the middle can be used to position the second equipment connection parts of different dimensions by bolts, and the elongated through-holes on both sides can be used to fix the second equipment connection parts by straps or screws.

[0024] (5) The mounting bracket has a U-shaped structure, which provides greater stability. The mounting bracket is hollowed out to meet the weight reduction requirements of the UAV and reduce wind resistance and weight during UAV flight.

[0025] (6) In order to reduce weight and to balance with the second equipment connection part on the second side, the main body of the first equipment connection part is provided with a first hollow part and a second hollow part, and the connection hole is provided in the area of ​​the main body of the first equipment connection part other than the hollow part.

[0026] (7) In this utility model, the support part and the second equipment connection part adopt a strip-shaped hollow structure, and the first equipment connection part is provided with a square through hole. The overall weight reduction of the mounting bracket reaches more than 30%.

[0027] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0037] Example 1

[0038] A specific embodiment of this utility model is as follows: Figure 1 As shown, a data link mounting bracket is disclosed for ground station data link installation, including a support part 1 and a first equipment connection part 2;

[0039] Support part 1 is located at the bottom; first device connection part 2 is located on the first side of support part 1;

[0040] The first device connection part 2 includes a bending structure 22 located at the top. The bending structure 22 is provided with antenna fixing holes 2211 and 2212 of various apertures and spacings. The antenna fixing holes 2211 and 2212 are used to fix the omnidirectional antenna 41 of the data link device 4.

[0041] The mounting bracket in this embodiment includes a support portion 1 and a first device connection portion 2. The support portion 1 is located at the bottom and supports the entire mounting bracket. The top of the first device connection portion 2 has a bending structure 22, which has antenna fixing holes 2211 and 2212 with various apertures and spacings. When the spacing of the antenna interfaces of the installed data link device 4 is less than 55mm, since its own antenna interface does not meet the requirement of an antenna spacing greater than 55mm, the radio frequency interface of the data link device 4 is fixed in the antenna fixing holes 2211 and 2212 of the mounting bracket to obtain the optimal spacing of the omnidirectional antenna 41. A cable is led out from the antenna interface to connect the radio frequency interface and the omnidirectional antenna 41, thereby improving the compatibility of different data link devices 4 and ensuring that the omnidirectional antenna 41 maintains a good attitude during flight to achieve stable data communication.

[0042] Specifically, to provide greater stability, the mounting bracket is designed with a U-shaped structure. For example, the mounting bracket can be welded or formed by one-piece bending. The mounting bracket is made of aluminum alloy. Furthermore, the U-shaped structure is hollowed out to accommodate the weight reduction requirements of the drone and reduce wind resistance and weight during flight, thereby improving the stability of the mounting bracket.

[0043] In this embodiment, the mounting bracket is made of aluminum alloy, and the support part 1, the first equipment connection part 2 and the second equipment connection part 3 adopt a strip-shaped hollow structure, which reduces the overall weight by more than 30% compared with ordinary brackets.

[0044] The support part 1 is used to directly connect with the drone fuselage. The support part 1 provides the mounting base for the entire mounting bracket and is located at the bottom of the U-shaped structure.

[0045] The bottom surface of the support part 1 is a flat or curved surface adapted to the curve of the drone fuselage or external connecting components. In this embodiment, the bottom surface of the support part 1 is a flat surface. Exemplarily, a mounting hole 11 is provided at the center of the support part 1 for connecting to the drone fuselage or the drone tripod.

[0046] The first device connection part 2 is disposed on the first side of the support part 1, and the second device connection part 3 is disposed on the second side of the support part 1, with the first side and the second side being disposed opposite to each other.

[0047] The first device connection portion 2 is used to install the data link device 4. Preferably, the first device connection portion 2 is perpendicular to the support portion 1, and the data link device 4 is installed on the outside of the first device connection portion 2. Exemplarily, to accommodate the square structure of the data link device 4, the main body 21 of the first device connection portion in this embodiment is set as a square base plate. Further, for weight reduction and to balance with the second device connection portion 3 on the second side, a hollow portion 211 is provided on the main body 21 of the first device connection portion. The hollow portion 211 includes a first hollow portion 2111 and a second hollow portion 2112, with the first hollow portion 2111 disposed above the second hollow portion 2112, and both the first hollow portion 2111 and the second hollow portion 2112 are square through-hole structures.

[0048] Furthermore, the main body 21 of the first device connection part, excluding the hollowed-out part 211, is provided with a variety of connection holes 212 with different diameters and spacings to adapt to data link devices 4 of different dimensions, thereby ensuring compatibility with different data link devices 4. Each type of connection hole 212 is set at a different spacing in a corresponding position to match the spacing of the mounting holes 11 of different data link devices 4.

[0049] Further, the first device connection part 2 is L-shaped, and its top has a bent structure 22 facing inward towards the mounting bracket. The bent structure 22 is configured as two flanges 221. Preferably, to improve the stability of the bracket and prevent the bracket from tilting outward, the flanges 221 extend inward. Antenna fixing holes of different sizes are provided on the flanges 221. Exemplarily, this embodiment shows a first antenna fixing hole 2211 and a second antenna fixing hole 2212, used to fix the omnidirectional antenna 41 of the data link device 4 with an antenna interface less than 55mm. Further, a notch 222 is provided between the two flanges 221. Figure 2 As shown, when installing data link device 4 with an antenna interface less than 55mm, since the spacing requirement for the omnidirectional antennas 41 is greater than 55mm, in order to obtain the optimal antenna spacing for data link device 4, the RF interface is fixed in the first antenna fixing hole 2211 or the second antenna fixing hole 2212 to fix the omnidirectional antennas 41. A cable is led out from the antenna interface of data link device 4, passes through the notch 222, and connects to the omnidirectional antennas 41. Figure 3 and Figure 4 As shown, other types of omnidirectional antennas 41 are directly fixed to the top of the data link device 4.

[0050] The second device connecting part 3 is used to install the second device connecting part 3. The second device connecting part 3 is perpendicular to the support part 1, and the second device connecting component is installed on the outside of the second device connecting part 3. The second device connecting part 3 is provided with a plurality of elongated through holes 31. Preferably, the elongated through holes 31 are arranged along the height direction of the second device connecting part 3. While reducing weight, the elongated through hole 31 in the middle can be used to position the second device connecting components of different sizes by bolts, and the elongated through holes 31 on both sides can be used to fix the second device connecting components by means of straps or screws.

[0051] The usage method of this embodiment is as follows:

[0052] Install the data link device 4 and the omnidirectional antenna 41. Align the mounting hole 11 of the data link device 4 with the corresponding connection hole 212 on the first device connection part 2, and screw in the screws to tighten and secure it. For data link devices 4 with an antenna interface spacing of less than 55mm, after fixing the data link device 4, fix the omnidirectional antenna 41 in the antenna fixing hole 2211 according to the optimal spacing through the RF connector and cable.

[0053] Install a directional antenna 42. For example... Figure 5 As shown, the omnidirectional antenna 41 is moved up and down along the second device connection part 3 until the omnidirectional antenna 41 is in the center position of the second device connection part 3, and then fixed by screws; the omnidirectional antenna 41 is fixed by wrapping it with straps through the elongated through holes 31 on both sides.

[0054] Install the mounting bracket onto the drone. Screw the bolt into the threaded hole at the bottom of the support section 1 and secure it to the drone using the tripod for fixing the mounting bracket. The tripod is adjustable to orient the mounting bracket in the desired direction, adapting to different signal reception directions and ensuring the antenna maintains a good attitude during flight.

[0055] Compared to traditional single-state data link mounting brackets, this embodiment features multiple antenna mounting holes 2211 to meet different antenna spacing requirements, satisfy the diverse needs of different data link devices 4, and improve the compatibility of data link device 4 installation. In this embodiment, the first device connection part 2 is provided with a variety of connection holes 212 of different shapes and sizes to adapt to data link devices 4 of different shapes and sizes, ensuring installation compatibility and preventing the incompatible bracket from loosening or even causing the data link device 4 to fall off. The bending structure 22 of the first device connection part 2 can support the fixation of the omnidirectional antenna 41 of the small data link device 4 to obtain the optimal antenna spacing. The elongated through hole 31 of the second device connection part 3 can adapt to the positioning of directional antennas 42 of different shapes and sizes. In this embodiment, the mounting bracket is made of aluminum alloy, and the support part 1 and the second device connection part 3 adopt a strip-shaped hollow structure. The first device connection part 2 has a first hollow part 2111 and a second hollow part 2112, and the overall weight reduction reaches more than 30%. Moreover, the overall mounting bracket is set as a U-shaped structure, which not only meets the weight reduction requirements of the UAV, but also reduces the wind resistance and weight of the UAV during flight, improves the stability of the mounting bracket, and ensures that the antenna maintains a good attitude during flight to achieve stable data communication.
