Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum composite panels, and in particular to an aluminum composite panel with a bending-resistant structure. Background Technology
[0002] To improve the sound insulation and heat preservation effect of aluminum composite panels, aluminum honeycomb panels can be used as the base material, and composite materials can be covered on one or both sides of the aluminum honeycomb panels to seal one or both ends of the honeycomb holes, ensuring the flatness of at least one side of the aluminum composite panel surface.
[0003] Aluminum honeycomb panels have a large number of honeycomb holes and are lightweight, but they have poor bending strength. Moreover, the honeycomb holes reduce the connection strength between the composite material and the substrate, making it easy for the composite material and the substrate to separate during bending, which further reduces the bending resistance of the composite. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide an aluminum composite panel with a bending-resistant structure, which improves the bending resistance and avoids the separation problem between the composite material and the substrate.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] An aluminum composite panel with a bending-resistant structure includes: a substrate, a plastic panel, and a bending-resistant core board. The substrate has multiple through holes. The bending-resistant core board is disposed on the top surface of the substrate to seal the top of the through holes. The bending-resistant core board has several injection holes arranged in an array, communicating with the through holes. The plastic panel is disposed on the top surface of the bending-resistant core board. The bottom surface of the plastic panel has plastic columns that are filled into the through holes below it through the injection holes, thus securing the bending-resistant core board to the top surface of the substrate to form a bending-resistant structure.
[0007] An aluminum panel is provided on the bottom surface of the substrate.
[0008] The bottom of the plastic column is in contact with the top surface of the aluminum panel.
[0009] The substrate is made of aluminum honeycomb panel.
[0010] The plastic panel and the plastic column adopt an integrated PVC structure.
[0011] The bending-resistant core plate is made of aluminum.
[0012] The number of through holes is greater than the number of injection holes.
[0013] The diameter of the injection hole is smaller than the diameter of the through hole.
[0014] The beneficial effects of this utility model are as follows: An aluminum composite panel with a bending-resistant structure strengthens the connection between the plastic panel and the substrate by filling some of the through holes with plastic columns, thereby achieving the clamping and fixing of the bending-resistant core board. This not only increases the bending resistance but also avoids the separation of the substrate, plastic panel and bending-resistant core board. Most of the through holes are retained, maintaining a certain sound insulation and heat preservation effect. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the structure of this utility model;
[0016] Figure 2 yes Figure 1 Top view of the medium-strength core board. Detailed Implementation
[0017] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.
[0018] like Figure 1 The aluminum composite panel with bending resistance structure shown includes: a substrate 3, a plastic panel 1, and a bending resistance core 2. The substrate 3 is provided with a plurality of through holes 31. In this embodiment, the substrate 3 is an aluminum honeycomb panel. The large number of through holes 31 forms a honeycomb structure, which is lightweight and helps to improve the sound insulation and heat preservation effect of the aluminum composite panel.
[0019] The bending-resistant core plate 2 is placed on the top surface of the substrate 3 to seal the top of the through hole 31. In this embodiment, the bending-resistant core plate 2 is made of aluminum plate. The bending resistance of the substrate 3 is improved by the composite of the bending-resistant core plate 2.
[0020] Several injection holes 21 communicating with through holes 31 are arranged in an array on the anti-bending core plate 2, such as... Figure 2 As shown, the number of through holes 31 is greater than the number of injection holes 21, such as... Figure 1 As shown, most of the through holes are retained to ensure a certain level of sound insulation and heat preservation.
[0021] The plastic panel 1 is placed on the top surface of the bending-resistant core board 2. The bottom surface of the plastic panel 1 has plastic columns 11 that are filled into the through-hole below it through injection holes 21. This allows the bending-resistant core board 2 to be riveted to the top surface of the substrate 3, forming a bending-resistant structure. The diameter of the injection hole 21 is smaller than the diameter of the through-hole 31, resulting in a stepped column structure for the plastic columns 11, which provides good riveting effect.
[0022] In this embodiment, the plastic panel 1 and the plastic column 11 adopt an integrated PVC structure. After the substrate 3 and the bending core board 2 are placed into the mold, the plastic panel 1 and the plastic column 11 are integrally molded. This results in high production efficiency, stable structure, avoidance of separation problems between the substrate 3, the bending core board 2 and the plastic panel 1, and good bending resistance.
[0023] To enable double-sided use, an aluminum panel 4 is provided on the bottom surface of the substrate 3, and the aluminum panel 4 further enhances the overall bending resistance. In this embodiment, the bottom of the plastic column 11 is in contact with the top surface of the aluminum panel 4, and the aluminum panel 4 is bonded together during the molding of the plastic column 11.
[0024] In addition, to improve structural stability, adhesive can be applied to the back of the aluminum panel 4 to achieve bonding between the back of the aluminum panel 4 and the bottom surface of the substrate 3.
[0025] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
