Description

Technical Field

[0001] The present invention belongs to the technical field of radar antennas, and in particular relates to a blind-matched interconnected radar antenna array and a mounting structure thereof. Background Art

[0002] With the rapid development of modern radar technology, antenna arrays are moving towards larger apertures and higher integration, resulting in a significant increase in the number of devices. This has led to tighter layout space, especially for high-frequency, high-density antenna arrays, where the spacing between elements is small and space resources are even more limited. Traditional antenna array interconnect structures typically use a discrete design, separating the electronic equipment from the mechanical structure, leading to the following problems:

[0003] Low space utilization: Traditional structures require a large amount of space for installation and wiring, which makes it difficult to meet the needs of compact layout of high-frequency arrays, limiting the lightweight and miniaturization development of antenna arrays.

[0004] Complex assembly and maintenance: The system uses screws or cables to connect point by point, which requires high installation precision. A large number of components need to be disassembled during maintenance, which is time-consuming and labor-intensive, affecting the combat readiness efficiency of the radar system.

[0005] Poor scalability and reconfigurability: The degree of modularity is insufficient, making it difficult to adapt to the needs of rapid expansion of the array or functional reconstruction, especially in application scenarios with high mobility requirements.

[0006] For low-frequency radar arrays, due to the larger spacing between units, space constraints are not yet prominent. However, for high-frequency, high-density arrays, existing technologies struggle to balance structural strength, heat dissipation performance, and the reliability of blind-mate interconnections. Although some modular design attempts have been made, they are often limited to a single function (such as mechanical support or circuit connection only), failing to achieve the integrated integration of structure, heat dissipation, and electrical signals. This results in insufficient utilization of space resources and hinders further improvement of radar performance. Summary of the Invention

[0007] In order to solve the technical problems existing in the background technology, the present invention proposes a radar antenna array and its installation structure, which adopts a modular blind-matching interconnection structure with integrated structure and function, significantly improves the overall space utilization, and solves the problem of tight space resources of high-frequency and high-density antenna arrays.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] A blind-mate interconnected radar antenna array surface mounting structure comprises: two first side panels, two second side panels and a plurality of plug-in boards, wherein the first side panels, the second side panels and the plug-in boards are all hollow rectangular shells, and a plurality of electronic equipment components constituting the antenna array surface are respectively installed inside. The two first side panels and the two second side panels are interconnected to form a rectangular frame, a blind-mate board is connected to one side of the rectangular frame, and the plurality of plug-in boards are inserted into the rectangular frame from the other side of the rectangular frame to be blind-mate interconnected with the blind-mate boards.

[0010] Furthermore, the two first side panels are arranged opposite to each other, and the two second side panels are respectively connected between the ends of the two first side panels. Both end walls of the second side panels are provided with mounting holes for connecting and fixing with the first side panels by screws.

[0011] Furthermore, multiple slide rails are arranged at equal distances on one side wall of the first side panel, and slide grooves corresponding to the slide rails are provided on both side end walls of the plug-in board. When the plug-in board is inserted into the rectangular frame, the slide grooves on both sides of the plug-in board are respectively adapted to connect with the corresponding slide rails on the two first side panels.

[0012] Furthermore, the distance between two adjacent slide rails on the first side plate is the same as the thickness of the inserting plate.

The positioning plates are provided with multiple positioning holes, and the bottom of the plug-in plate is provided with multiple positioning columns corresponding to the multiple positioning holes. When the plug-in plate and the blind matching plate are blind-matched and interconnected, the positioning columns at the bottom of the plug-in plate can be inserted into the positioning holes of any positioning plate and adapted to be connected to the corresponding positioning plate.

[0014] Furthermore, the width of the positioning plate is the same as the thickness of the inserting plate.

[0015] Furthermore, a liquid cooling distributor is connected to the bottom of the first side plate by screws, the top surface of the liquid cooling distributor is perpendicular to the side wall of the first side plate, and both ends of the blind matching plate are respectively connected to the top surfaces of the two liquid cooling distributors.

[0016] Furthermore, a plurality of positioning bosses are provided on the top surface of the liquid-cooled distributor, and the plurality of positioning bosses are respectively arranged corresponding to the plurality of slide rails on the first side panel. Positioning grooves corresponding to the positioning bosses are provided at both ends of the positioning plate, and the positioning grooves at both ends of the positioning plate are respectively adapted to be clamped on the positioning bosses on the top surfaces of the two liquid-cooled distributors.

[0017] Furthermore, a plurality of first blind water distribution joints are provided on the top surface of the liquid-cooled distributor, and the plurality of first blind water distribution joints are arranged one by one on one side of the plurality of positioning bosses. Through holes corresponding to the first blind water distribution joints are provided at both ends of the positioning plate, and two second blind water distribution joints are provided at the bottom of the plug-in plate. When the plug-in plate is adapted and connected to the positioning plate, the first blind water distribution joints on the top surfaces of the two liquid-cooled distributors respectively pass through the through holes at both ends of the corresponding positioning plates and adapt to the two second blind water distribution joints at the bottom of the plug-in plate.

[0018] Furthermore, a liquid cooling pipe is provided in the plugboard, and both ends of the liquid cooling pipe are respectively connected to the two second blind water distribution joints.

[0019] Beneficial effects of the present invention: The radar antenna array mounting structure provided in the present application is a main mounting frame composed of a first side panel and a second side panel.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figure 1-6 As shown, the present invention provides a blind-mate interconnected radar antenna array surface mounting structure, comprising: two first side panels 1, two second side panels 2 and a plurality of plug-in boards 3, wherein the first side panels 1, the second side panels 2 and the plug-in boards 3 are all hollow rectangular shells, and a variety of electronic equipment components constituting the antenna array surface are respectively installed inside. The two first side panels 1 and the two second side panels 2 are interconnected to form a rectangular frame, a blind-mate board 4 is connected to one side of the rectangular frame, and the plurality of plug-in boards 3 are inserted into the rectangular frame from the other side of the rectangular frame and blind-mate interconnected with the blind-mate board 4. The present application realizes a high degree of integration of structural bearing and electrical function by designing the first side panel 1 and the second side panel 2 of the rectangular frame as a hollow rectangular shell structure and integrating various electronic equipment components therein. This not only greatly reduces the additional installation space required for the traditional discrete structure, but also significantly improves the overall space utilization. At the same time, the electronic equipment is blindly connected to the blind mating board 4 in the form of a plug-in board 3, which completely changes the traditional cumbersome assembly process that requires docking cables and fasteners one by one, making the installation process simpler and faster, and effectively reducing installation errors caused by manual operation. The modular frame design also supports the plug-in and replacement of the plug-in board 3, which provides great convenience for the rapid functional reconstruction and capacity expansion of the antenna array, and is particularly suitable for the stringent requirements of modern radar systems for flexibility and scalability.

[0028] The two first side panels 1 are arranged opposite to each other, and the two second side panels 2 are respectively connected between the ends of the two first side panels 1. The two end walls of the second side panels 2 are provided with mounting holes 21, which are connected and fixed to the first side panels 1 by screws to form a rigid rectangular frame. This structural design significantly enhances the overall mechanical stability and can effectively resist the influence of external vibration and impact on internal electronic equipment. At the same time, the relative distance between the two first side panels 1 is determined structurally, which facilitates the installation of the plug-in board 3 and ensures that the plug-in board 3 meets the matching accuracy requirements before and after installation.

[0029] Multiple rails 11 are evenly spaced on one sidewall of the first side panel 1, and slots 31 corresponding to the rails 11 are provided on both sidewalls of the insert plate 3. When the insert plate 3 is inserted into the rectangular frame, the slots 31 on either side of the insert plate 3 mate with the corresponding rails 11 on the two first side panels 1. The cooperation between the rails 11 and the slots 31 provides precise linear guidance for the installation of the insert plate 3, ensuring that each insert plate 3 is smoothly and accurately inserted into place along the preset path. This completely avoids the offset and misalignment problems common in traditional installation methods, enabling quick and tool-free installation. This fundamentally changes the traditional assembly method that requires individual tightening, making the installation, replacement, and maintenance of the insert plate 3 extremely simple, significantly improving the system's maintainability and operational efficiency. This is particularly suitable for radar applications that require frequent maintenance and upgrades. The distance between two adjacent rails 11 on the first side panel 1 is the same as the thickness of the insert plate 3, achieving optimal arrangement of multiple insert plates 3 within a limited space, maximizing the utilization of the frame's internal space, and perfectly solving the key technical problem of limited space resources for high-frequency, high-density antenna arrays.

[0030] The blind-matching plate 4 is composed of a plurality of positioning plates 41, and the plurality of positioning plates 41 are respectively arranged in a one-to-one correspondence with the plurality of slide rails 11 on the first side plate 1. The positioning plates 41 are provided with a plurality of positioning holes 42, and the bottom of the plug-in plate 3 is provided with a plurality of positioning posts 32 corresponding to the plurality of positioning holes. When the plug-in plate 3 and the blind-matching plate 4 are blind-matched and interconnected, the positioning posts 32 at the bottom of the plug-in plate 3 can be inserted into the positioning holes 42 of any positioning plate 41 and adapted to be connected to the corresponding positioning plate 41. By adopting a high-precision positioning hole 42 and positioning post 32 matching method, the precise alignment between the plug-in plate 3 and the blind-matching plate 4 is ensured, which greatly improves the success rate and reliability of the blind-matching connection. At the same time, through the one-to-one correspondence between the positioning plate 41 and the slide rail 11, the flexible configuration and mixed combination of different functional modules are realized, so that the system has excellent functional scalability and adaptability, and can meet the needs of diverse tasks. Among them, the width of the positioning plate 41 is the same as the thickness of the plug-in plate 3, which completely eliminates the common assembly gap and space waste in traditional structures, and further improves the compactness of the blind-matching structure.

[0031] The bottom of the first side panel 1 is screwed to a liquid-cooling distributor 5. The top surface of the liquid-cooling distributor 5 is perpendicular to the sidewall of the first side panel 1. The two ends of the blind-mate board 4 are connected to the top surfaces of the two liquid-cooling distributors 5. By integrating the liquid-cooling distributor 5 with the structural frame, it serves as both a heat dissipation system and mechanical support. The vertical top surface of the liquid-cooling distributor 5 ensures the horizontal installation precision of the blind-mate board 4, providing a stable reference platform for the precise docking of the plug-in board 3. This multifunctional integrated design not only improves system reliability but also significantly reduces overall weight.

[0032] Specifically, the top surface of the liquid-cooling distributor 5 is provided with a plurality of positioning bosses 51, each corresponding to the plurality of slide rails 11 on the first side panel 1. Positioning grooves 43 corresponding to the positioning bosses 51 are provided at both ends of the positioning plate 41. The positioning grooves 43 at both ends of the positioning plate 41 are respectively adapted to be snapped onto the positioning bosses 51 on the top surfaces of the two liquid-cooling distributors 5. The precise snap-fit ​​structure between the positioning bosses 51 and the positioning grooves 43 enables rapid positioning and installation of the blind-matching plate 4. The top surface of the liquid-cooling distributor 5 is provided with a plurality of first blind water distribution joints 52, which are arranged one-to-one on one side of the plurality of positioning bosses 51. Through holes 44 corresponding to the first blind water distribution joints 52 are provided at both ends of the positioning plate 41. Two second blind water distribution joints 33 are provided at the bottom of the plug-in board 3. When the plug-in board 3 is adapted and connected to the positioning plate 41, the first blind water distribution joints 52 on the top surfaces of the two liquid-cooling distributors 5 respectively pass through the through holes 44 at both ends of the corresponding positioning plate 41 and adapt to the two second blind water distribution joints 33 at the bottom of the plug-in board 3. Among them, a liquid cooling pipe is provided inside the plug-in board 3 to achieve direct and precise cooling of high-power electronic devices. The two ends of the liquid cooling pipe are respectively connected to the two second blind water distribution joints 33, realizing the true plug-and-play function of the liquid cooling system. The precision-machined through-hole structure provides precise guidance for the docking of the water joints, ensuring the reliability of the cooling pipe connection.
