Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna device. Background Technology

[0002] A radome is a structural component that protects the antenna system from external environmental influences and is typically fixed to a base. To ensure effective heat dissipation from the antenna system, major heat sources, such as the antenna circuit board, are usually mounted on the base. Therefore, a support structure is needed on the base to support the antenna core above the antenna circuit board.

[0003] Therefore, the support structure must not only provide stable support for the antenna core but also secure the radome. How to appropriately reduce the cost of the support structure while ensuring these functions is a technical problem that urgently needs to be solved by those skilled in the art.

Detailed Implementation

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships, for example, A and / or B can represent: A alone, A and B at the same time, and B alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0052] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0053] like Figures 1 to 5 As shown, this application embodiment provides an antenna device, including a base 100, an radome 200, an antenna base plate 310, and multiple support structures 400; the base 100 and the radome 200 cooperate to form a closed space, and the antenna base plate 310 is located inside the closed space and fixed to the base 100 by the multiple support structures 400; the support structure 400 includes an antenna fixing hole 401, a base fixing hole 402, an radome fixing hole 403, an antenna fixing member 405, a base fixing member 404, and an radome 200 fixing member. Wherein:

[0054] Antenna mounting component 405 detachably connects support structure 400 and antenna base plate 310 by cooperating with antenna mounting hole 401; base mounting component 404 detachably connects support structure 400 and base 100 by cooperating with base mounting hole 402; antenna cover 200 mounting component detachably connects support structure 400 and antenna cover 200 by cooperating with antenna cover mounting hole 403.

[0055] In the antenna device provided in this application embodiment, the antenna base plate 310 is fixed to the base 100 by multiple support structures 400, ensuring the structural stability of the entire antenna device. Even under harsh weather conditions (such as strong winds or vibrations), this design can maintain the stability and reliability of the antenna. The base 100 and the radome 200 cooperate to form a closed space, which can effectively protect the antenna base plate 310 and its internal components from the influence of the external environment (such as dust, moisture, ultraviolet rays, etc.), thereby extending the service life of the antenna.

[0056] The support structure 400 is used not only to support and fix the antenna base plate 310, but also to fix the radome 200. Specifically, the support structure 400 includes an antenna fixing hole 401, a base fixing hole 402, a radome fixing hole 403, an antenna fixing component 405, a base fixing component 404, and a radome 200 fixing component. The antenna fixing component 405 and the antenna fixing hole 401 are used to connect and fix the support structure 400 to the antenna base plate 310; the base fixing hole 402 and the base fixing component 404 are used to connect and fix the support structure 400 to the base 100; the radome fixing hole 403 and the radome 200 fixing component are used to connect and fix the support structure 400 to the radome 200, further fixing the radome 200 and the base 100 relatively.

[0057] Furthermore, the antenna device provided in this application embodiment utilizes detachable connections such as the antenna fixing member 405 and the antenna fixing hole 401, the base fixing member 404 and the base fixing hole 402, and the antenna cover 200 fixing member and the antenna cover fixing hole 403. This allows for convenient assembly and disassembly, and the configuration of the antenna device can be adjusted according to different needs. For example, the stability of the antenna can be adjusted by increasing or decreasing the number of support structures 400, or different types of antenna base plates 310 can be replaced to adapt to different application scenarios. Because the components are detachably connected, it is not necessary to disassemble the entire device extensively when a component needs to be replaced or repaired. This not only improves maintenance efficiency but also reduces maintenance costs.

[0058] This application provides an antenna device in which the support structure 400 and the base 100 are detachably connected, allowing the support structure 400 and the base 100 to be manufactured separately. This not only reduces manufacturing difficulty but also facilitates later maintenance and upgrades, thereby reducing the manufacturing complexity and cost of the base 100, and also helps reduce material waste and production cycle, further reducing the overall manufacturing cost. Simultaneously, the support structure 400 connects to the antenna base plate 310, ensuring the structural stability of the antenna base plate 310 and the base 100; the support structure 400 also connects to and fixes the radome 200, ensuring the structural stability of the radome 200 and the base 100, which helps improve the working performance and reliability of the antenna device under various environmental conditions. Therefore, the antenna device provided in this application embodiment ensures the working performance and reliability of the antenna device while appropriately reducing costs.

[0059] In some embodiments, such as Figure 2 As shown, the antenna device also includes an antenna structure 300; the antenna structure 300 includes a first board 320 and an antenna core 330; the first board 320 is fixed to the base 100 and located between the base 100 and the antenna base plate 310; the antenna core 330 is fixed to the antenna base plate 310. The first board 320 serves as the main heat source of the antenna device. Due to the poor thermal conductivity of the radome 200, the first board 320 is fixed to the base 100 to facilitate heat dissipation to the outside of the antenna device. For heat dissipation, the base 100 is a metal base 100. The first board 320 can dissipate heat to the external environment through the metal base 100. The antenna core 330 is fixed to the antenna base plate 310 and supported on the base 100 by a support structure 400, with the first board 320 located between the antenna base plate 310 and the base 100. The support structure 400 between the base 100 and the antenna core 330 ensures that the two structures are fixed to prevent the first board 320 from being crushed or damaged.

[0060] In some embodiments, such as Figure 5 As shown, a heat dissipation fin 101 is provided on the side of the base 100 away from the enclosed space. The heat dissipation fin 101 is located on the side of the base 100 away from the first board 320 to facilitate heat dissipation into the environment. In a specific implementation, the heat dissipation fin 101 extends perpendicularly to the base 100, and multiple heat dissipation fins 101 form a flow channel that allows air circulation, so as to exchange heat with the outside air.

[0061] like Figure 5As shown, heat dissipation fins 101 are arranged on the side of the base 100 away from the enclosed space, increasing the contact area between the base 100 and the outside air, thereby improving heat transfer efficiency. This design helps to quickly dissipate the heat generated inside the base 100 to the external environment. The design of the heat dissipation fins 101 can significantly reduce the internal temperature of the base 100, avoiding performance degradation or damage to devices such as the first board 320 due to overheating. This is especially important for devices that need to operate for long periods or at high power. Through the layout of the heat dissipation fins 101, the temperature on the surface of the base 100 can be distributed more evenly, reducing the occurrence of localized overheating. This uniform heat distribution not only extends the service life of the device but also improves the overall performance stability.

[0062] It should be noted that the heat dissipation fins 101 can be designed in different shapes, sizes, and arrangements according to actual needs to meet the heat dissipation requirements under various complex working conditions. For example, in high humidity environments, heat dissipation fins 101 made of corrosion-resistant materials can be selected; in limited spaces, a compact design can be adopted, etc.

[0063] The specific structure of the support structure 400 can be selected in various ways. For example, in some embodiments of this application, such as... Figures 4-9 As shown, the support structure 400 includes a support column 410, and antenna fixing holes 401, base fixing holes 402 and radome fixing holes 403 are all provided on the support column 410.

[0064] like Figure 4 and Figure 5 As shown, the support column 410 integrates antenna mounting holes 401, base mounting holes 402, and radome mounting holes 403, reducing the number of independent components, simplifying the overall structure, and thus reducing assembly complexity and manufacturing costs. By setting multiple mounting holes on the support column 410, the space of the support column 410 is fully utilized, avoiding the space occupied by additional connectors, making the entire antenna device more compact. The mounting holes on the support column 410 are used to connect the antenna base plate 310, base 100, and radome 200, respectively, ensuring a firm connection between the various components, enhancing the structural stability of the entire antenna device, and improving its performance and reliability in harsh environments. Furthermore, the integration of three types of mounting holes in the support column 410—antenna mounting holes 401, base mounting holes 402, and radome mounting holes 403—simplifies the processing flow, reduces assembly steps, and improves production efficiency. At the same time, due to the reduction in the number of components, the number of failure points is also reduced, facilitating subsequent maintenance and repair.

[0065] Alternatively, in some other embodiments of this application, such as Figures 10-13As shown, the support structure 400 includes a support column 420 and a fixing block 430; the support column 420 is fixed to the base 100, and the antenna fixing hole 401 is provided in the support column 420; the base fixing hole 402 and the antenna cover fixing hole 403 are both provided in the fixing block 430.

[0066] like Figures 11-13 As shown, the support column 420 fixes the antenna base plate 310 to the base 100 through the antenna fixing hole 401. This design clearly defines the main function of the support column 420, ensuring the stability and reliability of the antenna base plate 310. The fixing block 430 connects the base 100 and the radome 200 through the base fixing hole 402 and the radome fixing hole 403. This division of labor makes the function of each component more singular, facilitating processing, assembly, and maintenance. The support column 420 is fixed to the base 100 and connected to the antenna base plate 310 through the antenna fixing hole 401, ensuring a firm connection between the antenna base plate 310 and the base 100. At the same time, the base fixing hole 402 and the radome fixing hole 403 on the fixing block 430 connect the base 100 and the radome 200 respectively, further enhancing the structural stability of the entire antenna device. By assigning different functions to the support column 420 and the fixing block 430, mutual interference between components is reduced, and the assembly process is simplified. The clear division of labor in this design makes the function of each component more singular, thereby reducing processing difficulty and cost. In one embodiment, the support column 420 is riveted to the base 100. The support column 420 can be a standard part, further reducing processing costs.

[0067] Alternatively, in some other embodiments of this application, such as Figures 14-16 As shown, the support structure 400 includes a first plate 440, a second plate 450, and a third plate 460, wherein the first plate 440 and the second plate 450 are opposite to each other, and the third plate 460 is connected between the first plate 440 and the second plate 450; an antenna fixing hole 401 is provided in the first plate 440; a base fixing hole 402 is provided in the second plate 450; and an antenna cover fixing hole 403 is provided in the third plate 460.

[0068] like Figure 15 and Figure 16As shown, the support structure 400 includes a first plate 440, a second plate 450, and a third plate 460. The first plate 440 and the second plate 450 are arranged opposite each other, while the third plate 460 connects the two. This three-plate structure forms a stable frame, providing good support for the antenna device and further reducing the weight of the base 100 and its processing cost. In specific implementations, the entire plate can be bent to form the support structure 400 with the first plate 440, the second plate 450, and the third plate 460; or the three plates, namely the first plate 440, the second plate 450, and the third plate 460, can be connected to form the support structure 400. The antenna fixing hole 401 on the first plate 440 is used to connect and fix the antenna base plate 310, ensuring the stability of the antenna base plate 310. The base fixing hole 402 on the second plate 450 is used to connect and fix the base 100, ensuring a firm connection between the support structure 400 and the base 100. The radome mounting holes 403 on the third plate 460 are used to connect and secure the radome 200, ensuring a stable connection between the radome 200 and the support structure 400. This functional partitioning makes the function of each component more singular, facilitating processing, assembly, and maintenance. The three-plate structure forms a stable triangular frame by assigning different functions to different plates. This design not only enhances the rigidity of the entire support structure 400 but also improves the overall stability of the antenna device.

[0069] When the support structure 400 only includes the support column 410, the form of the antenna mounting hole 401 can also be varied. For example, in some embodiments of this application, such as Figure 4 and Figure 5 As shown, the antenna mounting hole 401 is a through hole; the antenna fastener 405 passes through the base 100 and the antenna mounting hole 401 sequentially, and connects to the antenna base plate 310. The sequential passage of the antenna fastener 405 through the base 100 and the antenna mounting hole 401, and its connection to the antenna base plate 310, ensures a secure connection between the support structure 400, the base 100, and the antenna base plate 310. This design not only enhances the stability of the overall structure but also improves the performance and reliability of the antenna device. The through-hole design simplifies the assembly process, reducing assembly steps and time. Simultaneously, the clear and unambiguous connection method reduces potential failure points, facilitating subsequent maintenance and repair. Furthermore, the through-hole design allows for the use of different types of antenna fasteners 405, such as bolts and pins, increasing design flexibility and allowing for the selection of appropriate fastener types based on actual needs.

[0070] Alternatively, in other embodiments, such as Figures 7-9As shown, the antenna mounting hole 401 is a threaded hole; the antenna fastener 405 passes through the antenna base plate 310 and is threadedly connected to the antenna mounting hole 401. The threaded design of the antenna mounting hole 401 allows the antenna fastener 405 to pass through the antenna base plate 310 and be threadedly connected to the antenna mounting hole 401. This design provides a more robust connection, reducing the possibility of loosening due to vibration or external impact. The threaded connection makes the assembly process simpler and more efficient; installation is completed simply by screwing the antenna fastener 405 into the threaded hole. Simultaneously, this connection method facilitates disassembly and replacement, reducing maintenance difficulty and cost. In this embodiment, the antenna fastener 405 is a threaded connector, such as a screw. This embodiment reduces the length of the antenna fastener 405 (such as a screw) by changing its installation method, thereby reducing the overall weight of the base 100.

[0071] In addition to the antenna mounting hole 401, in some embodiments, such as Figures 4-5 as well as Figures 7-9 As shown, the base fixing hole 402 is a threaded hole, and the base fixing member 404 passes through the base 100 and is threadedly connected to the base fixing hole 402. Through the threaded connection, a tight fit is formed between the base fixing member 404 and the base fixing hole 402, ensuring a firm connection between the base 100 and the support structure 400. The threaded connection method makes the assembly process simpler and more efficient; installation can be completed simply by screwing the base fixing member 404 into the threaded hole. At the same time, this connection method facilitates disassembly and replacement, reducing maintenance difficulty and cost. In one embodiment, the base fixing member 404 is a screw, which passes through the base 100 and locks into the base fixing hole 402, thereby fixing the support column 410 to the base 100. In specific implementation, as shown... Figure 5 As shown, the base mounting hole 402 consists of two threaded holes. Alternatively, as... Figure 9 As shown, the base fixing hole 402 is a threaded hole, which can reduce the volume of the support column 410 accordingly.

[0072] In some embodiments, such as Figures 4-5 as well as Figures 7-9 As shown, the radome fixing hole 403 is a threaded hole, and the radome 200 fixing member passes through the radome 200 and is threadedly connected to the radome fixing hole 403. Through the threaded connection, a tight fit is formed between the radome 200 fixing member and the radome fixing hole 403, ensuring a firm connection between the radome 200 and the support structure 400, and reducing the possibility of loosening due to vibration or external impact.

[0073] In the case where the support structure 400 includes a support column 420 and a fixing block 430, such as Figure 10 and Figure 13As shown, antenna mounting hole 401 is a through hole; antenna fastener 405 passes through base 100 and antenna mounting hole 401 in sequence and is connected to antenna base plate 310. Base mounting hole 402 is a threaded hole, and base fastener 404 passes through base 100 and is threadedly connected to base mounting hole 402. Antenna cover mounting hole 403 is a threaded hole, and antenna cover 200 fastener passes through antenna cover 200 and is threadedly connected to antenna cover mounting hole 403.

[0074] In some embodiments, such as Figure 13 As shown, the support column 420 protrudes from the base 100 at a greater height than the fixing block 430. By adjusting the height ratio of the support column 420 and the fixing block 430, it is ensured that the support column 420 can better bear the main support function, while avoiding the impact of an excessively high fixing block 430 on the overall structural stability. The higher design of the support column 420 makes it more stable when bearing external loads, avoiding structural deformation or instability caused by insufficient height. The lower design of the fixing block 430 reduces the space occupied by other components, simplifying the overall structure.

[0075] In the case where the support structure 400 includes a first plate 440, a second plate 450, and a third plate 460, such as Figure 15 and Figure 16 As shown, antenna mounting hole 401 is a threaded hole; antenna fastener 405 penetrates antenna base plate 310 and is threadedly connected to antenna mounting hole 401. Base mounting hole 402 is a threaded hole, and base fastener 404 penetrates base 100 and is threadedly connected to base mounting hole 402. Antenna cover mounting hole 403 is a threaded hole, and antenna cover 200 fastener penetrates antenna cover 200 and is threadedly connected to antenna cover mounting hole 403.

[0076] In some embodiments, such as Figure 15 and Figure 16 As shown, the first plate 440 and the second plate 450 are symmetrically connected to both ends of the third plate 460, which is not only aesthetically pleasing, but also improves the overall structural balance and uniform stress distribution.

[0077] The symmetrical connection ensures more even stress distribution among the first plate 440, the second plate 450, and the third plate 460, avoiding structural deformation or damage caused by excessive stress on one side. Furthermore, symmetrical design typically implies consistent manufacturing processes, reducing manufacturing difficulty and cost. It also facilitates precise positioning and rapid installation during assembly.

[0078] In some embodiments, the first plate 440, the second plate 450, and the third plate 460 are an integral structure. For example, the support structure 400 is manufactured by stamping metal sheets.

[0079] By integrating the three panels into a single unit, assembly errors and loose connections that can occur with traditional separate connections are eliminated. Compared to separate connections, the integrated structure offers higher strength and rigidity, better withstanding external loads and impacts, and preventing structural failures due to weak connections. The integrated design reduces the number of parts, thereby lowering processing complexity and assembly difficulty. Furthermore, the elimination of additional connectors such as bolts further improves production efficiency and reduces manufacturing costs.

[0080] In some embodiments, such as Figure 17 and Figure 18 As shown, the base 100 is provided with a positioning groove 102 for cooperating with the support structure 400. In a specific implementation, the positioning groove 102 is formed by a recess in the base 100.

[0081] The positioning slot 102 design ensures precise alignment between the base 100 and the support structure 400 through mechanical engagement, reducing potential deviations during assembly. The fit between the positioning slot 102 and the support structure 400 makes the connection tighter and more stable, preventing structural instability caused by positional misalignment. This design not only enhances the overall structural rigidity but also improves the antenna device's performance and reliability. The positioning slot 102 design simplifies and simplifies the assembly process, reducing the time and difficulty of alignment adjustments. This design not only improves production efficiency but also reduces the possibility of assembly misalignment.

[0082] In one embodiment, such as Figure 17 As shown, and refer to Figure 6 The base 100 is provided with a positioning groove 102 for cooperating with the support column 410 and a mounting hole for the support column 410.

[0083] In another embodiment, such as Figure 18 As shown, and refer to Figure 14 As shown, the base 100 is provided with a positioning groove 102 for engaging with the third plate 460 of the support structure 400 and a mounting hole for the support structure 400.

[0084] In some embodiments, such as Figure 3 , Figure 6 as well as Figure 14 As shown, multiple support structures 400 are arranged at circumferential intervals along the edge of the base 100.

[0085] In one embodiment, such as Figure 18 As shown, and in combination Figure 14The base 100 is a circular plate, and six support structures 400 are installed on the base 100 through the positioning groove 102 and the mounting holes of the support structures 400. The six support structures 400 are evenly distributed along the circumference of the base 100. It should be noted that the base 100 can also be made of other shaped plates, such as square plates, oval plates, etc.

[0086] Multiple support structures 400 are arranged in a ring at intervals along the edge of the base 100. This layout ensures stable support for the base 100 in all directions by evenly distributing the support points. The ring-shaped intervals allow the support structures 400 to distribute the load more evenly, avoiding structural deformation or instability caused by excessive local stress. Because the support structures 400 are evenly distributed along the edge of the base 100, the center of gravity of the entire device is more stable, significantly improving its anti-overturning ability, especially advantageous when used on uneven ground or in dynamic environments such as on ships. The ring-shaped interval layout makes full use of the edge area of ​​the base 100, providing more installation space for other components such as circuit boards. This symmetrical and regular layout facilitates subsequent assembly and maintenance operations; for example, it makes it easier to achieve precise positioning and quick operation when installing or replacing the support structures 400.

[0087] In some embodiments, the antenna device further includes a cooling fan;

[0088] The cooling fan is located in an enclosed space and is situated on the side of the antenna structure 300 away from the base 100.

[0089] The antenna core 330 includes a second board, a radiating component, and a shielding component; the first board 320 of the antenna structure 300 is fixed to the base 100 and is located between the base 100 and the antenna base plate 310; the second board is disposed between the base 100 and the cooling fan.

[0090] Both the radiating and shielding components are fixed to the antenna base plate 310;

[0091] The shielding structure includes multiple shielding plates that surround the outside of the radiating component.

[0092] The cooling fan is used to promote airflow toward the base 100 so that the heat of the second board can be conducted to the base 100 through the air, and finally dissipated to the external environment by the base 100 and the heat dissipation fins 101 on the base 100.
