Description

Technical Field

[0001] The utility model relates to the technical field of aluminum honeycomb panels, in particular to an impact-resistant aluminum honeycomb panel. Background Technique

[0002] Aluminum honeycomb panels are applicable to civil buildings, vehicle and ship decoration, etc. They are the application of aerospace materials in the field of civil buildings. The entire processing process is completed in a modern factory, adopting the hot pressing forming technology. Due to the high heat conduction value between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized; there are small holes on the honeycomb aluminum skin, enabling the gas inside the panel to flow freely; the slidable installation buckle system will not cause structural deformation during thermal expansion and contraction.

[0003] Existing aluminum honeycomb panels are all composed of two layers of aluminum plates sandwiching a layer of honeycomb core, which is a single-layer design and is relatively thin. The overall strength is average, and the edges of the aluminum honeycomb panels are all in an open state, resulting in low strength at the edges and poor impact resistance. Therefore, in view of the above current situation, there is an urgent need to develop an impact-resistant aluminum honeycomb panel with a double-layer design, edge sealing for the edges, higher overall strength, and better impact resistance to overcome the deficiencies in current practical applications and meet the current needs. Content of the Utility Model

[0004] The purpose of the utility model is to provide an impact-resistant aluminum honeycomb panel to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An impact-resistant aluminum honeycomb panel, comprising an outer substrate layer, a sealing frame, an inner substrate layer and a honeycomb core. The number of the outer substrate layers is two, and the two outer substrate layers are respectively located on the upper and lower sides of the inner substrate layer. A honeycomb core is fixedly connected between the outer substrate layer and the inner substrate layer. A sealing frame is fixed on the outer sides of the outer substrate layer and the inner substrate layer. The sealing frame seals the four sides of the outer substrate layer and the inner substrate layer. A wear-resistant layer is arranged on the outer side of each outer substrate layer.

[0007] Preferably: The outer substrate layer, the sealing frame and the inner substrate layer are all made of aluminum alloy.

[0008] Preferably: The thicknesses of the outer substrate layer, the sealing frame and the inner substrate layer are all 3mm.

[0010] Preferably: Reinforcing ribs are fixed on the front and back sides of the inner substrate layer.

[0012] The beneficial effects of the present utility model are as follows: This impact-resistant aluminum honeycomb panel is composed of two inner base material layers, two honeycomb cores, and one outer base material layer, which increases the overall thickness and enhances the strength. The strength of the inner base material layer is increased by the reinforcing ribs, and the wear-resistant and impact-resistant performance of the outer surface of the outer base material layer is improved by the setting of the wear-resistant layer. The four sides of the outer base material layer and the inner base material layer are sealed by the sealing frame to enhance the strength at the edges, thereby making the overall strength higher and having better impact resistance. In summary, the present utility model adopts a double-layer design, seals the edges, has a higher overall strength, and better impact resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The following gives specific embodiments.

[0022] See Figures 1 to 5, in the embodiment of the present utility model, an impact-resistant aluminum honeycomb panel includes an outer substrate layer 1, a sealing frame 2, an inner substrate layer 3, and a honeycomb core 4. The number of the outer substrate layers 1 is two, and the two outer substrate layers 1 are respectively located on the upper and lower sides of the inner substrate layer 3. A honeycomb core 4 is fixedly connected between the outer substrate layer 1 and the inner substrate layer 3. A sealing frame 2 is fixed on the outer sides of the outer substrate layer 1 and the inner substrate layer 3. A sound insulation layer 201 is fixed inside the sealing frame 2. The sound insulation layer 201 absorbs the sound propagating at the edges. The sealing frame 2 seals the four sides of the outer substrate layer 1 and the inner substrate layer 3 to improve the strength at the edges. At the same time, the sound insulation performance is improved by reducing the sound propagation from the edges to the outside. The outer substrate layer 1, the sealing frame 2, and the inner substrate layer 3 are all made of aluminum alloy. Reinforcing ribs 301 are fixed on the front and rear sides of the inner substrate layer 3. The strength of the inner substrate layer 3 is increased by the reinforcing ribs 301, so that it has good strength itself to improve its impact resistance. The thicknesses of the outer substrate layer 1, the sealing frame 2, and the inner substrate layer 3 are all 3 mm. A wear-resistant layer 101 is provided on the outer side of each outer substrate layer 1. The wear-resistant layer 101 is sprayed with a polyurethane wear-resistant coating. The polyurethane wear-resistant coating has good wear and impact resistance, thereby improving the wear and impact resistance of the outer surface of the outer substrate layer 1.

[0023] Working principle: The impact-resistant aluminum honeycomb panel is composed of two inner substrate layers 3, two honeycomb cores 4, and one outer substrate layer 1 to increase the overall thickness and improve the strength. The strength of the inner substrate layer 3 is increased by the reinforcing ribs 301. The wear and impact resistance of the outer surface of the outer substrate layer 1 is improved by the setting of the wear-resistant layer 101. The four sides of the outer substrate layer 1 and the inner substrate layer 3 are sealed by the sealing frame 2 to improve the strength at the edges, so that the overall strength is higher and it has better impact resistance.
