Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb composite panel technology, and in particular to aluminum honeycomb composite panels. Background Technology

[0002] Aluminum honeycomb composite panels are a type of high-performance, lightweight composite material. They consist of a top panel, a middle core layer, and a bottom panel, which are firmly bonded together under high temperature and pressure using structural adhesives.

[0003] The existing aluminum honeycomb composite panels have the honeycomb core directly exposed on the sides after cutting, resulting in poor edge impact resistance. During handling and installation, they are prone to bumps that can cause the core material to collapse or the panel to delaminate. At the same time, when hit by falling objects, the impact force is directly transmitted to the honeycomb core, which can easily cause panel dents, core material crushing, or even panel cracking, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an aluminum honeycomb composite panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An aluminum honeycomb composite panel includes an aluminum honeycomb composite panel body. Reinforcing side plates are bonded to all four sides of the outer wall of the aluminum honeycomb composite panel body. An upper reinforcing plate and a lower reinforcing plate are bonded to the top and bottom of the aluminum honeycomb composite panel body. A groove is opened on the side of the upper and lower reinforcing plates near the aluminum honeycomb composite panel body. A polyurethane elastomer is embedded in the groove of the upper reinforcing plate, and a reinforcing rib assembly is embedded in the groove of the lower reinforcing plate. Furthermore, in a preferred configuration, the reinforcing rib assembly includes multiple transverse reinforcing ribs and longitudinal reinforcing ribs, with the multiple transverse reinforcing ribs and longitudinal reinforcing ribs arranged alternately.

[0006] In addition, in a preferred configuration, the upper reinforcing plate, the lower reinforcing plate and the adjacent reinforcing side plate are all connected by multiple bolts, and multiple mounting holes are equally spaced around the upper and lower reinforcing plates.

[0007] In addition, a preferred structure is that the upper reinforcing plate has multiple extending protrusions installed at equal intervals on the side away from the aluminum honeycomb composite panel body.

[0008] Furthermore, in a preferred configuration, the top and bottom surfaces of the reinforcing side plate are flush with the top and bottom surfaces of the aluminum honeycomb composite panel body, respectively.

[0009] Furthermore, in a preferred configuration, after the lower reinforcing plate is bonded to the aluminum honeycomb composite panel body, one side of the reinforcing rib assembly is attached to the aluminum honeycomb composite panel body.

[0010] Furthermore, in a preferred configuration, after the upper reinforcing plate is bonded to the aluminum honeycomb composite panel body, one side of the polyurethane elastomer is attached to the aluminum honeycomb composite panel body.

[0011] The beneficial effects of this utility model are as follows: In this invention, the aluminum honeycomb composite panel body is wrapped by the four reinforcing side plates, the upper reinforcing plate and the lower reinforcing plate together, which enhances the structural strength of the aluminum honeycomb composite panel. At the same time, the reinforcing rib assembly embedded in the lower reinforcing plate improves the bending stiffness and local load resistance of the aluminum honeycomb composite panel. Furthermore, the polyurethane elastomer embedded in the upper reinforcing plate enhances the impact resistance of the aluminum honeycomb composite panel. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 The aluminum honeycomb composite panel includes an aluminum honeycomb composite panel body 4. Reinforcing side plates 1 are bonded to all four sides of the outer wall of the aluminum honeycomb composite panel body 4. An upper reinforcing plate 21 and a lower reinforcing plate 3 are bonded to the top and bottom of the aluminum honeycomb composite panel body 4. The upper reinforcing plate 21 and the lower reinforcing plate 3 are provided with grooves on the side of the aluminum honeycomb composite panel body 4. A polyurethane elastomer 23 is embedded in the groove of the upper reinforcing plate 21, and a reinforcing rib assembly 31 is embedded in the groove of the lower reinforcing plate 3. Meanwhile, the reinforcing rib assembly 31 includes multiple transverse reinforcing ribs and longitudinal reinforcing ribs, with the multiple transverse reinforcing ribs and longitudinal reinforcing ribs arranged alternately.

[0016] Furthermore, the upper reinforcing plate 21, the lower reinforcing plate 3 and the adjacent reinforcing side plate 1 are all connected by multiple bolts, and multiple mounting holes are equally spaced around the upper reinforcing plate 21 and the lower reinforcing plate 3.

[0017] Furthermore, multiple extended protrusions 22 are installed at equal intervals on the side of the upper reinforcing plate 21 away from the aluminum honeycomb composite panel body 4.

[0018] Furthermore, the top and bottom surfaces of the reinforced side plate 1 are flush with the top and bottom surfaces of the aluminum honeycomb composite panel body 4, respectively.

[0019] At the same time, after the reinforcing plate 3 is bonded to the aluminum honeycomb composite panel body 4, one side of the reinforcing rib assembly 31 is attached to the aluminum honeycomb composite panel body 4.

[0020] Furthermore, after the upper reinforcing plate 21 is bonded to the aluminum honeycomb composite panel body 4, one side of the polyurethane elastomer 23 is bonded to the aluminum honeycomb composite panel body 4.

[0021] In this embodiment, the reinforcing side plates 1 and the upper reinforcing plate 21 and the lower reinforcing plate 3 work together to wrap and protect the aluminum honeycomb composite panel body, thereby enhancing its structural strength. Furthermore, by bonding the reinforcing side plates 1 around the aluminum honeycomb composite panel body 4, delamination or cracking of the aluminum honeycomb composite panel sides is prevented, thus improving the structural strength of the aluminum honeycomb composite panel sides. At the same time, the combination of the upper reinforcing plate 21 and the lower reinforcing plate 3 increases the overall thickness and rigidity of the aluminum honeycomb composite panel, thereby improving its compressive strength.

[0022] Meanwhile, the reinforcing rib assembly 31 and the reinforcing side plate 1 can effectively disperse the impact load when the aluminum honeycomb composite panel is under pressure, reduce the phenomenon of local deformation of the aluminum honeycomb composite panel, and improve the aluminum honeycomb composite panel's ability to resist impact and local load.

[0023] The upper reinforcing plate 21 and the lower reinforcing plate 3 are not only bonded to the adjacent reinforcing side plates, but also mechanically connected by multiple bolts. The combination of adhesive and bolts ensures the stability of the reinforcing side plates 1, upper reinforcing plate 21, lower reinforcing plate 3 and the aluminum honeycomb composite panel body 4 after they are connected.

[0024] The upper reinforcing plate 21 is embedded with a polyurethane elastomer 23. Polyurethane has excellent elasticity, toughness and energy absorption characteristics. When the aluminum honeycomb composite panel is subjected to external impact, it can effectively absorb and disperse the external impact force.

[0025] Meanwhile, the local stiffness of the top of the upper reinforcing plate 21 can be enhanced by setting multiple extended protrusions 22.

[0026] In this utility model, the aluminum honeycomb composite panel body 4 is wrapped by the four reinforcing side plates 1, the upper reinforcing plate 21 and the lower reinforcing plate 3, which enhances the structural strength of the aluminum honeycomb composite panel. At the same time, the reinforcing rib assembly 31 embedded in the lower reinforcing plate 3 improves the bending stiffness and local load resistance of the aluminum honeycomb composite panel. Furthermore, the polyurethane elastomer 23 embedded in the upper reinforcing plate 21 enhances the impact resistance of the aluminum honeycomb composite panel.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
