Description

Technical Field

[0001] This utility model belongs to the field of panel material technology, and in particular relates to a lightweight composite panel with a sealed frame. Background Technology

[0002] In numerous fields such as architectural decoration, furniture manufacturing, and vehicle interiors, the requirements for panel materials are becoming increasingly stringent. Lightweight, high-strength, aesthetically pleasing, and easy-to-process materials have become the mainstream market demands. Traditional panel materials, such as solid wood, metal panels, and single-layer honeycomb panels, while possessing certain advantages in some aspects, often reveal their limitations in practical applications.

[0003] Solid wood panels are widely loved for their natural texture and color, adding warmth and elegance to decorative spaces. However, solid wood panels are relatively heavy, which not only increases the difficulty of transportation and installation, but also makes them prone to deformation due to changes in environmental humidity during use, affecting their appearance and usability.

[0004] Metal sheets are renowned for their high strength and durability, making them particularly suitable for applications requiring resistance to significant external forces or wear. However, metal sheets are difficult to process, requiring specialized equipment and techniques, resulting in high production costs. Furthermore, the textures and colors of metal sheets are relatively limited, making it difficult to meet diverse and personalized decorative needs.

[0005] Honeycomb panels, as a new type of lightweight material, possess advantages such as lightweight, high strength, and good sound and heat insulation properties due to their unique honeycomb structure, and are widely used in various fields. The emergence of honeycomb panels has brought new choices to the panel material market. However, single-layer honeycomb panels may not be able to meet the higher requirements for strength and stability in certain applications. Especially in situations where they need to withstand large external forces or maintain shape stability over a long period of time, the performance of single-layer honeycomb panels may be insufficient.

[0006] In summary, traditional panel materials have many limitations in terms of weight, strength, aesthetics, and processing performance, making it difficult to meet the increasingly diverse demands of the market. While honeycomb panels have many advantages, the performance of single-layer honeycomb panels still needs improvement in certain specific applications. Therefore, developing a panel material that is both lightweight and high-strength, aesthetically pleasing and easy to process has become an urgent problem to be solved in the current market. This patent is based on this background technology and proposes an improved honeycomb panel structure to meet the market demand for high-performance panel materials. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0026] Please refer to Figures 1 to 9A lightweight composite panel with a frame is disclosed, comprising a substrate 1, a decorative panel 2 laminated to the surface of the substrate, and a backing panel 3 laminated to the back of the substrate. The substrate is a double-layered, interlocked honeycomb panel, which significantly improves the panel's lightweight and strength. The honeycomb structure itself is lightweight and high-strength, and the double-layered interlocking arrangement further enhances these structural advantages. This design not only reduces the overall weight of the panel but also allows for more even distribution of pressure when subjected to external forces, improving the panel's resistance to compression and bending. Simultaneously, the double-layered honeycomb structure enhances the panel's sound and heat insulation performance, enabling it to maintain stable performance in various environments. A frame 4 is provided around the honeycomb panel, providing effective edge protection. During processing, transportation, and use, the edges of the honeycomb panel are the most vulnerable to damage. The frame not only strengthens the edges but also prevents bumps and scratches. Furthermore, the frame can conceal irregularities at the edges of the honeycomb panel, making the overall appearance of the panel more aesthetically pleasing. Meanwhile, the integrated design of the frame and substrate improves the overall structural stability of the panel, making it less prone to deformation or damage during long-term use. The upper surface of the frame is flush with the upper surface of the substrate, and the decorative panel is adhered to both the frame and the upper surface of the substrate. Furthermore, the outer edge of the frame is flush with the edge of the decorative panel, resulting in a more unified and aesthetically pleasing overall appearance. The flush edges not only enhance the visual appeal of the panel but also reduce gaps and protrusions at the edges, preventing the accumulation of dust and dirt. The flush design also facilitates panel installation and removal, improving construction convenience. In addition, the flush edges enhance the panel's durability, reducing wear or damage caused by improper edge treatment.

[0027] Preferably, the substrate is a double-layer staggered injection-molded honeycomb integrated panel, composed of several double-layer honeycomb units 1-1 spliced ​​together, with a non-woven fabric adhesive transition layer 1-2 laminated on the surface of the substrate. This design cleverly combines the advantages of injection molding and honeycomb structures. Injection molding ensures the precision and consistency of the substrate, while the double-layer honeycomb structure endows the substrate with lightweight and high-strength characteristics. The non-woven fabric adhesive transition layer 1-2 laminated on the surface of the substrate further enhances the overall performance of the panel.

[0028] The non-woven fabric bonding transition layer 1-2 not only improves the bonding strength between the substrate and the decorative panel or backing board, but also acts as a buffer and shock absorber, effectively preventing panel cracking or delamination caused by temperature changes or external impacts. Simultaneously, the non-woven fabric material has excellent breathability and moisture absorption, helping to regulate the humidity balance inside the panel and reducing deformation or expansion caused by humidity changes. Furthermore, the non-woven fabric bonding transition layer makes the panel surface smoother and more even, providing a good foundation for subsequent decorative processing and enhancing the overall aesthetics and durability of the panel. This combination of technical features makes this lightweight composite panel outstanding in terms of lightweight, strength, aesthetics, durability, and ease of processing.

[0029] Preferably, the sealing frame 4 includes a straight edge banding strip 4-1 and a corner edge banding strip 4-2, achieving seamless splicing and stable installation of the sealing frame. The straight edge banding strip includes an upper support plate 4-10 and a lower support plate 4-11, with a vertical plate 4-12 connecting the upper and lower support plates. An arc-shaped transition plate 4-13 is provided on the outer side of the vertical plate between the upper support plate and the vertical plate, forming a corner splicing groove 4-14 with the upper support plate and the vertical plate. The cross-sectional shape of the corner edge banding strip is consistent with that of the straight edge banding strip, allowing the corner edge banding strip to be easily and accurately inserted into the corner splicing groove of the straight edge banding strip, achieving quick and stable splicing. This design not only improves the installation efficiency of the sealing frame but also enhances its overall strength and stability, providing reliable protection for the panel's fixation and protection. Simultaneously, this seamless splicing design also enhances the overall aesthetics of the panel, making it more in line with modern aesthetic requirements. At both ends of the corner edge banding strip 4-2, there are splicing tenons 4-20 with the same shape as the corner splicing groove. This not only enhances the support of the edge banding frame, but also provides a precise docking interface for splicing the corner edge banding strip through the design of the arc transition plate 4-13 and the corner splicing groove 4-14.

[0030] A socket plate 4-15 is also provided on the vertical plate on the side of the lower support plate. A socket slot is provided on the side of the base plate, and the socket plate is inserted into the socket slot. This achieves a tight fit between the socket plate and the socket slot. This design enhances the connection stability and robustness of the structure, and improves the overall load-bearing capacity and deformation resistance. At the same time, the socket connection method is simple and easy to implement, facilitating installation and disassembly, improving construction efficiency, reducing maintenance costs, and demonstrating significant technical and economic benefits.

[0031] Preferably, the lining plate is one or a composite of two of the following: stainless steel plate, aluminum plate, metal alloy plate, wood plate, glass fiber reinforced plastic plate, carbon fiber reinforced plastic plate, polypropylene plate, polyethylene plate, polyvinyl chloride plate, and ABS plate. The composite lining plate combines the advantages of different materials, ensuring structural strength while achieving the dual goals of lightweighting and aesthetics. This diverse selection of lining plates meets the specific needs of different fields for lightweight composite panels, enhancing the product's market competitiveness and application value.

[0032] Preferably, the decorative panel is one or a combination of two of the following: metal panel, stone panel, glass panel, and wood panel. Metal panels, with their high gloss, strong texture, and wear resistance, are suitable for modern and minimalist styles. Stone panels, with their natural texture, unique feel, and good weather resistance, are suitable for occasions seeking a natural and high-end decorative effect. Glass panels, being transparent or semi-transparent, can create a light and airy visual effect, increasing the sense of depth in a space. Wood panels, with their warm and natural colors and textures, add a touch of warmth and comfort to the interior environment.

[0033] Composite decorative panels combine the advantages of different materials, satisfying diverse decorative needs while improving the overall performance and durability of the panels. This design gives lightweight composite panels broader application prospects and market competitiveness in fields such as architectural decoration and furniture manufacturing.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
