Description

Technical Field

[0001] This application relates to the field of radar system-specific components, and in particular to a real-time adjustable radar wave reflector bracket. Background Technology

[0002] As an all-weather, all-time environmental sensing technology, radar detection and identification systems have been widely used in remote sensing measurement, meteorological observation, and other scenarios. In the field of radar calibration technology, electromagnetic wave reflectors, through the design of regular shapes and structures (such as spheres, trihedral reflectors, etc.), form stable electromagnetic scattering characteristics, which can meet the requirements of wide-frequency and wide-angle observation, and are widely used in radar calibration devices, calibration instruments, and other equipment.

[0003] In recent years, the emergence of real-time tunable electromagnetic wave reflection characteristics material plates (hereinafter referred to as tunable material plates) has brought revolutionary breakthroughs to reflector technology. These material plates typically consist of a backing layer and a tunable reflectivity material layer. The tunable reflectivity material layer, based on a periodic array structure with loaded electronic devices, a mechanically adjustable reflective unit array, or tunable materials, dynamically adjusts the surface impedance characteristics through electronic control and mechanical regulation. This allows for dynamic control of parameters such as the amplitude, phase, and polarization of the reflected wave, enabling the reflector to possess real-time feature reconstruction capabilities and providing a technical means to realize advanced functions such as multi-scene dynamic simulation. However, current research mainly focuses on the performance optimization of the tunable material plate itself. A systematic solution for the engineering application of tunable material plates in reflectors has not yet been formed, particularly the lack of dedicated structural designs to support the tunable material plate, which hinders the practical application of this technology. Utility Model Content

[0004] In order to provide stable structural support for the adjustable material plate of the real-time adjustable radar wave reflector, this application provides a real-time adjustable radar wave reflector bracket.

[0005] The real-time adjustable radar wave reflector bracket provided in this application adopts the following technical solution:

[0006] A real-time adjustable radar wave reflector bracket includes a support frame, the support frame including two or three planar fixing frames, the multiple planar fixing frames being fixedly connected to form a dihedral or trihedral structure; the real-time adjustable radar wave reflector includes two or three adjustable material plates, the multiple adjustable material plates forming a dihedral or trihedral structure, each adjustable material plate having an edge sealing strip detachably connected to its edge, and each of the planar fixing frames having a receiving groove for accommodating the edge sealing strip.

[0007] During installation, edge banding strips are used to seal the four edges of the adjustable material plate to protect it. Then, the edge banding strips are snapped into the corresponding receiving slots to fix the adjustable material plate to the corresponding flat mounting frame. A stable connection is formed between the real-time adjustable radar wave reflector composed of multiple adjustable material plates and the support frame.

[0008] Furthermore, the adjustable material plate includes a conductive back plate, an adjustable material layer, and a spacer layer disposed between the two. The edge sealing strip is provided with a conductive back plate slot and an adjustable material layer slot, which are respectively used to accommodate the edge of the conductive back plate and the edge of the adjustable material layer.

[0009] The conductive back plate edge and the adjustable material layer plate edge of the adjustable material plate are respectively inserted into the conductive back plate slot and the adjustable material layer plate slot of the edge sealing strip, thereby completing the sealing of the four edges of the adjustable material plate by the edge sealing strip.

[0010] Furthermore, the planar fixing frame has a central hollow structure.

[0011] The openwork structure helps reduce the weight of the supporting frame.

[0012] Furthermore, a cross beam is fixedly installed in the central hollow area of ​​the planar fixing frame.

[0013] The cross beam helps improve the stability of the flat mounting bracket. At the same time, the cross beam can fit against the back of the adjustable material plate, thereby improving the stability of the adjustable material plate installation.

[0014] Furthermore, the surface of the cross beam protrudes from the inner bottom wall of the receiving groove.

[0015] Furthermore, the height by which the surface of the cross beam protrudes from the bottom wall of the receiving groove is equal to the thickness of the sealing strip on one side of the conductive backplate slot.

[0016] Furthermore, when the edge banding strip is inserted into the receiving groove, the surface of the cross beam contacts the back of the adjustable material plate.

[0017] In this way, a stable connection can be achieved between the adjustable material plate and the edge banding strip and the flat fixing frame.

[0018] Furthermore, the surface of the cross beam is bonded to the back of the adjustable material plate.

[0019] Furthermore, the bottom wall of the receiving groove is bonded to the sealing strip.

[0020] The bonding process further improves the stability of the connection between the adjustable material board and the edge banding strip and the flat fixing frame.

[0021] Furthermore, the two adjacent planar fixing frames are at a 90° angle to each other.

[0022] The 90° angle design ensures the electromagnetic wave reflection / retracing function of the dihedral or trihedral radar wave reflector, which is adjustable in real time.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This application proposes a real-time adjustable radar wave reflector support structure with practical engineering value. This structure ensures the relative positional accuracy of the adjustable material plates while providing reliable mechanical support. As the core load-bearing component of the radar wave reflector, this application helps solve the problem of stable deployment of radar wave reflectors and provides key technical support for the engineering realization of novel reflectors.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Reference Figure 1 The real-time adjustable radar wave reflector includes two or three adjustable material plates 4, and multiple adjustable material plates 4 form a dihedral or trihedral structure. To ensure the electromagnetic wave reflection / retrospection function of the real-time adjustable radar wave reflector, adjacent adjustable material plates 4 are at a 90° angle to each other. In this embodiment, the real-time adjustable radar wave reflector is a trihedral structure, and the adjustable material plates 4 are rectangular.

[0032] In the prior art, the adjustable material plate 4 includes a conductive back plate, an adjustable material layer plate, and a spacer layer disposed between the two; wherein, the conductive back plate is a carbon fiber back plate or other conductive material, the adjustable material layer plate is a radar wave reflection characteristic adjustable material layer, and the spacer layer is an air layer.

[0033] This application discloses a real-time adjustable radar wave reflector bracket for supporting a real-time adjustable radar wave reflector. (Refer to...) Figure 2 The real-time adjustable radar wave reflector bracket includes a support frame 1, which includes two or three planar fixing frames 2. The multiple planar fixing frames 2 are fixedly connected to form a dihedral or trihedral structure.

[0034] In this embodiment, the support frame 1 is a trihedral structure, and the planar fixing frame 2 is rectangular. Any two adjacent planar fixing frames 2 form a 90° angle. The support frame 1 is made of metal or plastic and can be manufactured using an integral molding method, or the planar fixing frames 2 can be fixedly connected by welding or bonding. The dimensions of the planar fixing frame 2 are determined according to the dimensions of the adjustable material plate 4. The reference thickness range of the planar fixing frame 2 is 3-50mm, and the reference side length is 50-5000mm.

[0035] Reference Figure 1 and Figure 3 Each adjustable material plate 4 has an edge sealing strip 3 detachably connected to its edge. The edge sealing strip 3 is provided with a conductive back plate slot 31 and an adjustable material layer slot 33, which are used to accommodate the edges of the conductive back plate and the adjustable material layer, respectively. There is a spacer layer area 32 between the conductive back plate slot 31 and the adjustable material layer slot 33. The edge sealing strip 3 is made of metal or plastic, and its size is determined according to the size of the adjustable material plate 4. The widths of the conductive back plate slot 31 and the adjustable material layer slot 33 are adapted to the thicknesses of the conductive back plate and the adjustable material layer, respectively.

[0036] During encapsulation, the conductive backplate edge and the adjustable material layer edge of the adjustable material plate 4 are respectively inserted into the conductive backplate slot 31 and the adjustable material layer slot 33 of the sealing strip 3, thereby completing the encapsulation of the adjustable material plate 4. The sealing strip 3 protects the adjustable material plate 4. The rectangular adjustable material plate 4 is encapsulated using at least two sealing strips 3. In this embodiment, four sealing strips 3 are used to encapsulate the four sides of the adjustable material plate 4.

[0037] Reference Figure 2 Each flat mounting bracket 2 has a receiving groove 21 for accommodating the edge banding strip 3. Specifically, each flat mounting bracket 2 has four receiving grooves 21, which are used to accommodate the edge banding strips 3 on the four sides of the adjustable material plate 4. The depth of the receiving groove 21 is determined according to the thickness of the flat mounting bracket 2, and the reference depth of the receiving groove 21 is 0.5-50mm.

[0038] After the adjustable material plate 4 is encapsulated, the edge sealing strip 3 is inserted into the corresponding receiving groove 21, thereby fixing the adjustable material plate 4 onto the corresponding planar fixing frame 2. A stable connection is formed between the real-time adjustable radar wave reflector composed of multiple adjustable material plates 4 and the support frame 1. To improve the stability of the connection, the edge sealing strip 3 can be glued to the inner bottom wall of the receiving groove 21.

[0039] To avoid mutual compression between adjacent adjustable material plates 4, refer to Figure 2 A gap d is provided between the edge of the receiving groove 21 and the adjacent planar fixing frame 2, with a reference range of 10-30mm. Due to this gap, when the adjustable material plate 4 is fixed to the support frame 1, the included angle of the two adjacent planar fixing frames 2 and the two adjacent adjustable material plates 4 together form a receiving space, and the feed wire of the adjustable material plate 4 can be connected within this receiving space.

[0040] To reduce the weight of support frame 1, refer to Figure 2 The planar fixing frame 2 has a central hollow structure. Furthermore, to improve the stability of the planar fixing frame 2, a cross beam 22 is fixedly installed in the central hollow area of ​​the planar fixing frame 2.

[0041] Reference Figure 3 and Figure 4 The surface of the cross beam 22 protrudes from the inner bottom wall of the receiving groove 21, and the height h of the cross beam 22 protruding from the inner bottom wall of the receiving groove 21 is equal to the thickness h of the sealing strip 3 on one side of the conductive back plate slot 31. The reference range of h is 1-5mm.

[0042] Thus, when the edge banding strip 3 is inserted into the receiving groove 21, the surface of the cross beam 22 contacts the back of the adjustable material plate 4 (i.e., the back of the conductive back plate). Furthermore, the surface of the cross beam 22 is bonded to the back of the adjustable material plate 4, thereby achieving a stable connection between the adjustable material plate 4, the edge banding strip 3, and the flat fixing frame 2.

[0043] The real-time adjustable radar wave reflector bracket provided in this application ensures the relative position accuracy of the adjustable material plate 4 while providing reliable mechanical support for the adjustable material plate 4.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
