Description

Technical Field

[0001] This utility model relates to the field of antenna reflector manufacturing technology, specifically to a foamed carbon fiber composite antenna reflector. Background Technology

[0002] Antenna reflectors are conductive curved or flat surfaces used to concentrate and reflect electromagnetic waves in a specific direction. They are widely used in wireless communication and satellite communication. In a surface antenna, an antenna reflector is a conductive curved or flat surface that concentrates and reflects electromagnetic waves emitted from the feed source in a specific direction as required. Its main function is to enhance the transmission or reception of signals. By focusing electromagnetic waves, the reflector increases the gain in a specific direction, thereby improving communication quality and signal strength.

[0003] However, existing antenna reflectors have a uniform thickness and few embedded parts, and the reflectors are low in precision, low in strength and heavy in weight, which affects the normal use of the antenna reflectors. Therefore, we propose a foamed carbon fiber composite material antenna reflector. Utility Model Content

[0004] In view of the problems existing in the reflective surface of the foamed carbon fiber composite antenna, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a foamed carbon fiber composite antenna reflector, which solves the problems that existing antenna reflectors have uniform thickness, few embedded parts, low precision, low strength, and heavy weight, which affect the normal use of the antenna reflector.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A foamed carbon fiber composite antenna reflector includes antenna surface segments, an equipment mounting surface, and metal embedded parts. Each antenna surface segment is a foamed foam core, and the foamed foam core is high-density epoxy resin foam. Each antenna surface segment has a carbon fiber prepreg on its surface, and each antenna surface segment has a mounting groove. Each mounting groove has a limiting groove inside, and each mounting groove has a metal embedded part inside. Each metal embedded part has limiting protrusions on both sides, and the limiting protrusions respectively engage with the limiting grooves.

[0007] Preferably, the outer surfaces of the plurality of antenna surface blocks are provided with equipment mounting surfaces.

[0008] Preferably, the edges of the outer surfaces of the plurality of antenna surface blocks are provided with recessed structures.

[0009] Preferably, the thickness of the multiple antenna surface segments is not uniform, and the thicknesses of the multiple antenna surface segments are 10mm, 5mm, 6mm, and 9mm, respectively.

[0010] Preferably, an antenna surface center disk is provided between the plurality of antenna surface blocks, and a mounting hole is provided through the surface of the antenna surface center disk.

[0011] Preferably, the density of the foam core of the multiple antenna surface segments is 80 kg / m³.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, by adopting a non-uniform thickness design for the antenna surface segments, breaks through the limitation of the uniform thickness of existing reflective surfaces. It can adapt to the structural support of specific areas according to the different intensity requirements of electromagnetic wave reflection. At the same time, the edges of the segments are provided with recessed structures, which can flexibly adapt to the edge constraints of the installation space and avoid the problem of poor scene adaptability caused by the single structure. Furthermore, the metal embedded parts are fixed in the mounting groove of the antenna surface segments through the snap-fit ​​structure of the limiting protrusions and limiting grooves. Compared with the existing embedded parts that are simply placed or have a few adhesives, this design can prevent the embedded parts from loosening or shifting during use, improve the structural stability, and can flexibly add embedded parts in the mounting grooves of multiple antenna surface segments according to the subsequent equipment installation requirements, solving the functional limitations of the limited number of embedded parts in existing reflective surfaces.

[0013] 2. This utility model features a high-density epoxy resin foam core with a density of only 80 kg / m³ as the core of the antenna surface segmentation, combined with a lightweight and high-strength carbon fiber prepreg surface layer. Compared with traditional metal or high-density composite material reflectors, the overall weight is significantly reduced, which can reduce the load on the antenna support structure. It is especially suitable for weight-sensitive wireless and satellite communication equipment. At the same time, the carbon fiber prepreg covering the surface of the foam core can significantly enhance the surface stiffness and deformation resistance of the reflector. The foam core itself has a certain degree of support, and the snap-fit ​​structure with the metal embedded parts forms an integrated force system of core, surface layer and embedded parts, avoiding the problem of insufficient strength caused by the loose structure of existing reflectors, and improving the reflector's anti-aging and anti-interference capabilities during long-term use.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a foamed carbon fiber composite antenna reflector.

[0019] This utility model provides, for example Figure 1-4 The illustrated foamed carbon fiber composite antenna reflector includes antenna surface segments 1, equipment mounting surface 2, and metal embedded parts 3. Each antenna surface segment 1 is a foamed core 4, and the foamed core 4 is a high-density epoxy resin foam. Each antenna surface segment 1 has a carbon fiber prepreg 5 on its surface, and each antenna surface segment 1 has a mounting groove 6. Each mounting groove 6 has a limiting groove 7 inside, and each mounting groove 6 has a metal embedded part 3 inside. Each metal embedded part 3 has limiting protrusions 8 on both sides, and the limiting protrusions 8 respectively engage with the limiting grooves 7. The mechanical properties of the carbon fiber prepreg 5 can compensate for the insufficient surface stiffness of the foamed core 4.

[0020] This utility model discloses a foamed carbon fiber composite material antenna reflector, wherein the outer surface of each of the multiple antenna surface blocks 1 is provided with an equipment mounting surface 2, providing a flat mounting plane for communication equipment.

[0021] This utility model discloses a foamed carbon fiber composite material antenna reflector, wherein the edges of the outer surfaces of the multiple antenna surface blocks 1 are provided with recessed structures 9, which can avoid obstacles in the installation space.

[0022] This utility model discloses a foamed carbon fiber composite material antenna reflector. The thickness of the multiple antenna surface blocks 1 is uneven, and the thicknesses of the multiple antenna surface blocks 1 are 10mm, 5mm, 6mm and 9mm respectively. The energy concentration area is improved by thicker blocks to enhance structural stability and reflection accuracy, while the energy weakness area is balanced by thinner blocks to balance weight and function.

[0023] This utility model discloses a foamed carbon fiber composite material antenna reflector. A central disk 10 is provided between multiple antenna surface blocks 1. The surface of the central disk 10 is provided with mounting holes 11 to fix the entire reflector to the external support frame and ensure the overall position stability of the reflector during use.

[0024] This utility model discloses a foamed carbon fiber composite antenna reflector. The density of the foam core 4 of the multiple antenna surface blocks 1 is 80 kg / m³. On the one hand, the low density of the foamed foam is used to achieve overall lightweighting and reduce the load on the supporting structure. On the other hand, the structural stability of the foam core 4 can serve as the basic support for the reflector and provide an installation carrier for the surface carbon fiber prepreg 5 and embedded parts.

[0025] In use, the antenna surface segment 1 uses a high-density epoxy resin foam core 4 as its core matrix. On one hand, the low-density characteristics of the foam achieve overall lightweighting, reducing the load on the supporting structure. On the other hand, the structural stability of the foam core 4 serves as the basic support for the reflector, providing an installation carrier for the surface carbon fiber prepreg 5 and embedded parts. The carbon fiber prepreg 5 laid on the surface of the antenna surface segment 1 forms a high-strength surface layer, whose mechanical properties compensate for the insufficient stiffness of the foam core 4 surface layer. Simultaneously, as the conductive surface layer of the reflector, it ensures effective reflection of electromagnetic waves, preventing surface deformation or damage from affecting the accuracy of electromagnetic wave reflection. Meanwhile, the metal embedded part 3, through its limiting protrusions 8 on both sides, forms a snap-fit ​​engagement with the limiting groove 7 in the mounting groove 6 of the antenna surface segment 1. This structure enables precise positioning of the embedded part, preventing displacement under conditions such as vibration and temperature changes. Furthermore, the metal embedded part 3 serves as a connection carrier for subsequent communication equipment, allowing external... The device is securely connected to the reflector, expanding the reflector's functional adaptability. Multiple antenna surface blocks 1 form an overall reflector structure through the antenna surface center plate 10. The mounting holes 11 of the center plate are used to fix the entire reflector to the external support frame, ensuring the overall positional stability of the reflector during use. The recessed structure 9 at the edge of the blocks can avoid obstacles in the installation space. The device mounting surface 2 on the outer surface provides a flat mounting plane for the communication equipment, ensuring the convenience and accuracy of subsequent equipment assembly. The design of the antenna surface blocks 1 with uneven thickness can form differentiated structural support and reflection characteristics in different areas according to the energy distribution requirements of electromagnetic wave reflection. The energy concentration area is improved by thicker blocks to enhance structural stability and reflection accuracy, while the energy weakness area is balanced by thinner blocks to balance weight and function. Finally, the entire reflector, through the conductive properties of the surface carbon fiber prepreg 5, concentrates and reflects the electromagnetic waves emitted by the feed source in a preset direction, thereby improving signal gain and enhancing communication quality and signal strength.
