[0002] Honeycomb aluminum panels are a lightweight, high-strength composite material. Traditional honeycomb aluminum panels consist of two aluminum panels sandwiching an aluminum honeycomb core layer. Traditional honeycomb aluminum panels require on-site grooving during bending, which removes some aluminum material, leading to material loss and high manufacturing costs. Furthermore, grooving generates aluminum shavings, polluting the working environment, and adds time, resulting in low work efficiency.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0006] Each of the unit honeycomb panels includes two flat bottom plates, a honeycomb layer is disposed between the two flat bottom plates, and a second adhesive layer is disposed between the honeycomb layer and the two flat bottom plates;

[0007] The filling structure includes an inverted trapezoidal strip, which is movably attached to the inclined surfaces of two unit honeycomb panels. A third adhesive layer is provided on the lower wall of the inverted trapezoidal strip, and the third adhesive layer is movably attached to the bent bottom plate.

[0008] Preferably, the angle between one side of each of the two unit honeycomb panels and the opposite wall is 90 degrees.

[0009] Preferably, a fourth adhesive layer is movably bonded between the upper wall of the inverted trapezoidal strip and both of the unit honeycomb panels.

[0010] Preferably, a weight-reducing cavity is provided at the center of the inverted trapezoidal strip.

[0011] Preferably, the two flat base plates have the same thickness, and the honeycomb layer and the second adhesive layer disposed between the two flat base plates have the same thickness.

[0012] Preferably, the thickness of the first adhesive layer between the two unit honeycomb panels and the wall surface of the bent bottom plate is the same.

[0013] Beneficial effects

[0014] This utility model provides a foldable honeycomb aluminum panel, which has the following advantages compared with the prior art: In the production stage of the honeycomb panel, the whole modular honeycomb panel is cut into two unit honeycomb panels at a 45° bevel in one go, replacing the traditional process of bending and grooving the honeycomb panel on site, which improves work efficiency, saves materials, eliminates aluminum shavings pollution, and keeps the environment clean.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figure 1-3 Folded honeycomb aluminum panel, including a bent base plate 1, on which modular honeycomb panels are provided;

[0021] Specifically, the modular honeycomb panel includes two unit honeycomb panels. Both unit honeycomb panels are symmetrically attached to the upper wall of the bent base plate 1 through the first adhesive layer 2. One side of each unit honeycomb panel has an inclined surface opposite to the wall. A filling structure is provided between the inclined surface of one side of each unit honeycomb panel and the bent base plate 1.

[0022] It should be noted that the bent base plate 1 is made of aluminum plate. Two or more unit honeycomb panels are bonded to the bent base plate 1 through the first adhesive layer 2. When bonding the unit honeycomb panels, the beveled surfaces of adjacent unit honeycomb panels are bonded accordingly, such as... Figure 1-2As shown, the two inclined surfaces are set in a V-shape, and there is a certain distance between two adjacent honeycomb panels; the first adhesive layer 2 can be a modified epoxy structural adhesive film or a polyurethane hot melt adhesive film, which has the characteristics of strong and tough bonding and resistance to bending fatigue.

[0023] Specifically, each unit of the honeycomb panel includes two flat bottom plates 3, a honeycomb layer 4 is provided between the two flat bottom plates 3, and a second adhesive layer 5 is provided between the honeycomb layer 4 and the two flat bottom plates 3.

[0024] It should be noted that both flat base plates 3 and the honeycomb layer 4 are made of aluminum. When manufacturing the modular honeycomb panel, the honeycomb layer 4 is first bonded to the two flat base plates 3 using the second adhesive layer 5 to form a single modular honeycomb panel. Once the second adhesive layer 5 is completely dry, the cutting tool can be tilted at a 45-degree angle. Figure 3 As shown, the entire modular honeycomb panel is cut off at an angle. When manufacturing and cutting the modular honeycomb panel, its dimensions are designed to meet the target folded honeycomb aluminum panel dimensions after bending, so that the entire modular honeycomb panel forms two unit honeycomb panels. Then, one of the unit honeycomb panels is flipped over, making the angled surfaces of the two unit honeycomb panels V-shaped, as shown. Figure 1-2 As shown; the second adhesive layer 5 can be made of aerospace-grade epoxy film or phenolic-nitrile adhesive, which has the characteristics of high rigidity structural bonding and shear resistance;

[0025] The filling structure includes an inverted trapezoidal strip 6, which is movably attached to the inclined surface of two unit honeycomb panels. A third adhesive layer 7 is provided on the lower wall of the inverted trapezoidal strip 6, which is movably attached to the bent bottom plate 1.

[0026] It should be noted that the inverted trapezoidal strip 6 can be made of rubber. When there is no need to bend the honeycomb aluminum panel, the inverted trapezoidal strip 6 is placed between two unit honeycomb panels to support the two adjacent unit honeycomb panels. The third adhesive layer 7 is used to movably connect the inverted trapezoidal strip 6 and the bending base plate 1. When it is necessary to bend the honeycomb aluminum panel, simply tear off the inverted trapezoidal strip 6, and the inverted trapezoidal strip 6 will detach from the third adhesive layer 7. Then, the base plate 1 can be folded and bent. There is no need to cut grooves on site, which solves the problem of aluminum shavings flying during grooving and ensures the cleanliness of the work site. At the same time, compared with bending after grooving, cutting the whole modular honeycomb panel into two unit honeycomb panels saves materials and avoids the material waste caused by grooving. The third adhesive layer 7 can be made of silicone-based pressure-sensitive adhesive, which has the characteristic of leaving no trace after tearing.

[0027] Preferably, and further still, the angle between one side of the two unit honeycomb panels and the wall surface is 90 degrees;

[0028] As a preferred and further option, a fourth adhesive layer 8 is movably bonded between the upper wall of the inverted trapezoidal strip 6 and the two unit honeycomb panels. This is used for the movable connection between the inverted trapezoidal strip 6 and the two unit honeycomb panels, preventing the folded honeycomb aluminum panel from undergoing significant deformation when bending is not required, and preventing the bottom plate 1 from bending when bending is required. When bending is required, the fourth adhesive layer 8 can be peeled off to separate the inverted trapezoidal strip 6 from the two unit honeycomb panels. The fourth adhesive layer 8 can be made of silicone-based pressure-sensitive adhesive, which has the characteristic of leaving no residue after peeling.

[0029] As a preferred and further option, a weight-reducing cavity 9 is provided in the center of the inverted trapezoidal strip 6 to reduce the overall weight of the folded honeycomb aluminum panel.

[0030] Preferably, the two flat bottom plates 3 have the same thickness, and the honeycomb layer 4 and the second adhesive layer 5 disposed between the two flat bottom plates 3 have the same thickness.

[0031] Preferably, and further still, the first adhesive layer 2 disposed between the two unit honeycomb panels and the upper wall of the bent base plate 1 has the same thickness.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
