Description

Technical Field

[0001] This utility model relates to the field of sheet metal structure technology, and more specifically, to an aramid honeycomb sheet metal structure. Background Technology

[0002] In today's diverse industrial and civil sectors, honeycomb panels, as a fundamental structural and functional material, directly impact the quality, safety, comfort, and economy of the entire project or product. This is driven by continuous technological advancements and increasingly stringent requirements for material performance across various industries.

[0003] For example, application publication number CN117922112A discloses a carbon fiber aramid honeycomb composite board, its preparation process and application. The carbon fiber aramid honeycomb composite board consists of at least one layer of aramid honeycomb core material containing polymer microspheres, carbon fiber plates located above and below the aramid honeycomb core material, and glass fiber cloth located between the two carbon fiber plates. The number of carbon fiber plates is twice the number of aramid honeycomb core material layers, and the glass fiber cloth has one less layer than the number of aramid honeycomb layers.

[0004] In the above-mentioned cases, when subjected to out-of-plane impact or localized concentrated loads, the load transmission path between the honeycomb cells is relatively simple, which can easily lead to excessive stress concentration in certain areas, resulting in insufficient impact resistance. This makes the honeycomb wall prone to buckling or collapse, and the panel and core material may debond, thus causing structural failure and insufficient impact resistance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aramid honeycomb panel structure with improved structural strength.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An aramid honeycomb panel structure includes a top panel and a bottom panel. A first support portion and a second support portion are provided between the top plate and the bottom plate. The first support portion has two parts, and the second support portion is placed between the two first support portions. The second support section and the first support section are interspersed. The first and second support parts are fixedly connected to the top and bottom panels on their respective sides. The first and second support parts have the same structure. Both the first and second support sections include a first column, a second column, a third column, and several connecting plates. The first and second columns are fixedly connected to each other, and the second and third columns are fixedly connected to the first and third columns, respectively, by connecting plates. A cavity is formed between the first column, the second column, the third column, and the connecting plate. The cavity is in the shape of an equilateral triangle. A positioning plate is provided inside the cavity. One end of the positioning plate is fixed to the first column, and the other end is fixed to the connecting plate between the second and third columns.

[0007] The present invention is further configured such that: a plurality of reinforcing ribs are provided on the outer wall of the positioning plate, and the reinforcing ribs are fixedly connected to the positioning plate.

[0008] The present invention is further configured such that: a plurality of evenly distributed clamping plates are provided in the top plate and the bottom plate respectively, the clamping plates are fixed to the top plate and the bottom plate respectively, and there are through holes between the top plate and the adjacent clamping plates and between the bottom plate and the adjacent clamping plates.

[0009] The present invention is further configured such that the positioning plate is placed at the center of the connecting plate between the second column and the third column.

[0010] The present invention is further configured such that: both ends of the first column, the second column and the third column are provided with locking discs, the locking discs are in the shape of circular plates, and the locking discs are fixed to the first column, the second column and the third column respectively.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. Improved overall resistance to deformation of the sheet material: By setting up a first support and a second support, and adopting an alternating layout, a spatial network structure with mutual support and a better force transmission path is formed. Its core consists of a first column, a second column, and a third column connected by connecting plates to form a stable triangular frame, and the resulting cavity is an equilateral triangle shape.

[0012] 2. Improved impact resistance: The positioning plate inside the triangular cavity and the reinforcing ribs on the outer wall of the positioning plate diffuse stress to the entire triangular frame, preventing core material collapse caused by stress concentration. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figures 1 to 3 As shown, the aramid honeycomb panel structure includes a top panel 1 and a bottom panel 2. Both the top panel 1 and the bottom panel 2 have multiple horizontally distributed clamping plates 8, which are fixed to the top panel 1 and the bottom panel 2 respectively. The clamping plates 8 increase the strength of the top panel 1 and the bottom panel 2.

[0018] There are through holes 9 between the top plate 1 and the adjacent clamping plate 8, and between the bottom plate 2 and the adjacent clamping plate 8. The through holes 9 can disperse external forces and further improve the overall structural stability.

[0019] Between the top panel 1 and the bottom panel 2, there are two sets of first supporting parts 3 and second supporting parts 4, which are distributed vertically. There are two first supporting parts 3, and the second supporting parts 4 are located between the two first supporting parts 3. The second support part 4 and the first support part 3 are staggered, which can more evenly distribute external forces and improve the overall stability of the board. The first support part 3 and the second support part 4 are fixedly connected to the top board surface 1 and the bottom board surface 2 on both sides, respectively, to ensure the firmness of the connection between the parts.

[0020] The first support part 3 and the second support part 4 have the same structure, both including a first column 301, a second column 302, a third column 303, and three connecting plates 304. The first column 301 and the second column 302 are fixedly connected to each other, and the second column 302 and the third column 303 are fixedly connected to the first column 301 and the third column 303, forming a stable frame structure.

[0021] The first column 301, the second column 302, and the third column 303 are each provided with a circular locking disc 10 at both ends. The locking disc 10 is fixed to the first column 301, the second column 302, and the third column 303 respectively. The locking disc 10 can prevent the first column 301, the second column 302, and the third column 303 from slipping when subjected to force, thereby further enhancing the structural stability of the support part.

[0022] A cavity 5 is formed between the first column 301, the second column 302, the third column 303 and the connecting plate 304. The cavity 5 is in the shape of an equilateral triangle. An equilateral triangle has extremely high stability and can withstand large external forces without deformation, thereby greatly improving the structural strength of the entire plate.

[0023] A positioning plate 6 is installed inside the cavity 5. One end of the positioning plate 6 is fixed to the first column 301, and the other end is fixed to the center of the connecting plate 304 between the second column 302 and the third column 303.

[0024] The positioning plate 6 further enhances the structural stability of the support part, effectively preventing it from twisting or deforming under stress. Because the positioning plate 6 and the connecting plate 304 are fixed at the center, the positioning plate 6 can more evenly distribute external forces, improving the structural stability of the support part.

[0025] Several reinforcing ribs 7 are installed on the outer wall of the positioning plate 6. The reinforcing ribs 7 are fixed to the positioning plate 6. The reinforcing ribs 7 can increase the strength and rigidity of the positioning plate 6, making it more stable when subjected to external forces, thereby further improving the structural strength of the entire support part.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
