[0002] An aluminum-aluminum honeycomb core door panel is composed of an aluminum-aluminum honeycomb core board and a decorative panel. The aluminum-aluminum honeycomb core board is formed by gluing aluminum alloy plates on both sides of the aluminum-aluminum honeycomb core board with an adhesive, and the decorative panel is simply attached to the surface. Among them, the aluminum-aluminum honeycomb core board has a regular hexagonal honeycomb structure. The regular hexagonal honeycomb structure is the most reasonable and scientific structure with the least amount of raw materials used under the same strength, the lightest weight and the highest strength.
[0003] The aluminum honeycomb core board is generally arranged inside the decorative panel. However, during the use process, the four corners of the indoor door panel, especially the lower part of the door panel, are often subject to collisions. If the door panel is still in the form of a simple combination of an aluminum honeycomb core board and a decorative panel, depressions will still occur. Therefore, this application proposes an indoor door panel of an all-aluminum alloy door. Content of the Utility Model

At the same time, a reinforcing frame and a fixing strip are installed between the four sides of the two outer plates at the front and back and the sound insulation filling layer. At the same time, a reinforcing rib assembly is arranged inside the reinforcing frame. Therefore, with a small increase in the amount of materials used, the local structural strength around the door panel can be greatly increased. The sound insulation filling layer adopts a combination form of an aluminum honeycomb core, a first sound insulation cotton and a second sound insulation cotton. Except for the first sound insulation cotton and the second sound insulation cotton, the door panel has an all-aluminum structure, and depressions are not likely to occur on the outside and around of the door panel during daily use.
