Description

Technical Field

[0001] This utility model relates to the technical field of wooden decorative parts, specifically to a novel wooden ABA structure decorative part. Background Technology

[0002] The traditional ABA structure decorative component manufacturing process follows a relatively fixed procedure. First, the two sheets constituting layer A are cut to ensure their dimensions match the requirements of the final product. After cutting, to enhance the aesthetics and design of the decorative component, the visible surface of the sheets undergoes "front-edge shaping," using methods such as cutting and polishing to create specific lines, curves, and other shapes. Then, an aluminum sandwich decorative strip is used as layer B, connecting the two sheets of layer A to form a complete ABA structure decorative component.

[0003] Traditional ABA structure decorative components face difficulties in adjusting their thickness. Aluminum sandwich decorative strips are standardized prefabricated parts with fixed thicknesses. Adjusting the overall thickness of an ABA structure decorative component requires custom-making aluminum sandwich strips of the corresponding thickness, leading to extended production cycles, increased customization costs, and an inability to flexibly respond to diverse thickness requirements. Furthermore, due to the material differences between aluminum sandwich decorative strips and wood panels, inconsistent thermal expansion and contraction during production can cause deformation or cracking of the ABA structure decorative component, affecting its overall aesthetics and lifespan.

[0030] Please see Figures 1 to 4 This embodiment provides a novel wooden ABA structure decorative component, comprising: a top plate 1, a middle plate 3, and a bottom plate 2. The top plate 1, the middle plate 3, and the bottom plate 2 are all made of wood. The middle plate 3 is disposed between the top plate 1 and the bottom plate 2. The bottom of the top plate 1 is provided with a first receiving groove 11, and the top of the middle plate 3 is received in the first receiving groove 11. The top of the bottom plate 2 is provided with a second receiving groove 21, and the bottom of the middle plate 3 is received in the second receiving groove 21. The middle plate 3 is connected to the top plate 1 and the bottom plate 2 respectively.

[0031] The ABA structure is a composite structure formed by stacking three layers of materials in sequence, presenting a symmetrical shape of "outer layer-middle layer-outer layer". "A" represents the outer layer materials on both sides, and "B" represents the middle connecting layer material.

[0032] Top panel 1, middle panel 3, and bottom panel 2 are all made of wood, forming the three-layer main structure of the decorative component. Top panel 1 and bottom panel 2 are the outer layers of the decorative component, corresponding to the upper and lower A layers in a traditional ABA structure decorative component. Middle panel 3 is the middle layer connecting the two outer layers, corresponding to the B layer in a traditional ABA structure decorative component.

[0033] The materials for the top plate 1, middle plate 3 and bottom plate 2 can be solid wood, wood composite board, etc., and the top plate 1, bottom plate 2 and middle plate 3 are all flat structures, which are easy to process and convenient to support other items on the top plate 1.

[0034] The first receiving groove 11 is a groove structure machined on the bottom surface of the top plate 1 (i.e., the side that contacts the middle plate 3). The first receiving groove 11 is located near the edge area of ​​the top plate 1. The cross-sectional shape of the first receiving groove 11 can be designed as rectangular, trapezoidal, or dovetail, etc., according to the processing technology and assembly requirements. The length of the first receiving groove 11 is the same as the length of the top plate 1, the width is adapted to the width of the top of the middle plate 3, and the depth of the first receiving groove 11 is determined according to the thickness of the middle plate 3 and the required fitting strength to ensure that the top of the middle plate 3 can be smoothly inserted and form a stable fit.

[0035] In this embodiment, the depth of the first receiving groove 11 is 4mm, which can meet the thickness requirements of most users for decorative parts, so that the decorative parts can be mass-produced and production costs can be reduced.

[0036] The second receiving groove 21 is a groove structure machined on the top surface of the bottom plate 2 (i.e. the side that contacts the middle plate 3). The position, shape, length, width, depth and other parameters of the second receiving groove 21 are completely corresponding to and adapted to the first receiving groove 11 of the top plate 1, so as to ensure that the bottom of the middle plate 3 can be accurately embedded and realize the symmetrical assembly of the three-layer structure.

[0037] The number of first receiving slots 11 and second receiving slots 21 can be multiple. In this embodiment, the number of first receiving slots 11 and second receiving slots 21 are both two.

[0038] After the top of the middle plate 3 is embedded into the first receiving groove 11 of the top plate 1, a fixed connection is formed through a specific method (such as bonding, threaded connection, etc.); after the bottom of the middle plate 3 is embedded into the second receiving groove 21 of the bottom plate 2, a fixed connection is formed through the same method, so that the top plate 1, the middle plate 3 and the bottom plate 2 form a solid whole structure.

[0039] Specifically, the dimensions of the first receiving groove 11 and the second receiving groove 21 are matched with the upper and lower dimensions of the middle plate 3. When the middle plate 3 is embedded in the groove, the inner wall of the groove will form a circumferential constraint on the middle plate 3, restricting the displacement of the middle plate 3 in the horizontal direction (i.e., the direction perpendicular to the thickness of the decorative part), and avoiding interlayer misalignment caused by external force or vibration.

[0040] By connecting the middle plate 3 with the top plate 1 and the bottom plate 2 into a whole, the originally independent three-layer panels are transformed into a structural unit that shares the load. When the decorative component is subjected to external loads (such as compression or bending forces), the load is transferred to the entire structure through the interlayer connections, rather than being borne by a single panel, thereby improving the overall load-bearing capacity and deformation resistance of the decorative component.

[0041] Top plate 1, middle plate 3, and bottom plate 2 are all made of wood, and their physical properties (such as modulus of elasticity and coefficient of thermal expansion and contraction) are highly consistent. When environmental conditions change, the deformation trends of top plate 1, middle plate 3, and bottom plate 2 are basically consistent, which can significantly reduce the internal stress caused by material differences and fundamentally solve the cracking problem caused by inconsistent deformation between metal and wood in traditional ABA structures.

[0042] When it is necessary to change the thickness of the decorative parts, only the thickness of the middle plate 3 needs to be changed. Since the middle plate 3 is made of wood, wood processing is more convenient than processing and customizing a new aluminum sandwich layer. It can flexibly and quickly adjust the thickness of the decorative parts and reduce production costs.

[0043] Compared with the prior art, this embodiment accommodates the wooden middle board 3 in the first accommodating groove 11 and the second accommodating groove 21, so that the top plate 1, the middle board 3 and the bottom plate 2 form a whole, which improves the overall rigidity and bending resistance of the decorative part and ensures that the decorative part is not prone to interlayer separation or deformation due to external force. The overall thickness of the decorative part can be adjusted by replacing the middle board 3 of different thicknesses, without the need to customize special aluminum interlayer, which simplifies the production process of the decorative part and reduces the production cost.

[0044] In this embodiment, the top of the middle plate 3 is bonded to the top plate 1, and the bottom of the middle plate 3 is bonded to the bottom plate 2.

[0045] The middle board 3 is bonded to the inner walls of the first receiving groove 11 and the second receiving groove 21 by wood glue. The wood glue can be one or more of white glue, PUR wood glue and polyurethane glue.

[0046] By using wood glue to bond the middle board 3 to the top board 1 and the bottom board 2, the processing of decorative parts becomes simpler and production efficiency is improved.

[0047] In some embodiments, the middle plate 3 is connected to the top plate 1 and the bottom plate 2 by screw threads.

[0048] In some embodiments, the middle plate 3 is provided with a locking block, and the top plate 1 and the bottom plate 2 are provided with locking slots at corresponding positions. The locking block is embedded in the locking slot, thereby connecting the middle plate 3 to the top plate 1 and the bottom plate 2.

[0049] In this embodiment, the top plate 1 and the bottom plate 2 have the same dimensions, and the thickness of both the top plate 1 and the bottom plate 2 is 18mm.

[0050] The length and width of the top plate 1 and the bottom plate 2 are exactly the same, ensuring that the decorative parts are symmetrical and making the decorative parts more beautiful.

[0051] Setting the thickness of top plate 1 and bottom plate 2 to 18mm facilitates batch processing, reduces the complexity of processes such as cutting and grinding, and improves production efficiency. At the same time, the 18mm thickness of top plate 1 is sufficient to meet the load-bearing and impact resistance requirements of most interior decoration scenarios, avoiding deformation caused by excessive thinness. If top plate 1 and bottom plate 2 are too thick, it will increase production costs and make the decorative parts too heavy and unsightly.

[0052] Please see Figure 4 In this embodiment, the top and bottom surfaces of the middle plate 3 are provided with rough structures 31.

[0053] Rough structure 31 refers to the non-smooth surface (such as serrated texture 311, frosted surface, etc.) formed by processing the top and bottom surfaces of the middle plate 3, which is used to increase the contact area between the middle plate 3 and the top plate 1 and the bottom plate 2, and improve the bonding strength.

[0054] The rough surface allows the wood glue to penetrate into the tiny grooves on the board surface during the curing process, improving the bonding strength between the glue layer and the board. At the same time, after the wood glue is cured, it can form a mechanical interlock with the inner walls of the first receiving groove 11 and the second receiving groove 21, further restricting the relative sliding between the middle plate 3 and the top plate 1 and the bottom plate 2.

[0055] Please see Figure 4 In this embodiment, the rough structure 31 is a serrated texture 311.

[0056] Serrated 311 refers to the continuous convex and concave structure with a serrated shape processed on the top and bottom surfaces of the middle plate 3.

[0057] The grooves on the top and bottom surfaces of the middle board 3 can store more wood glue, increase the glue layer thickness, improve the bonding strength between the middle board 3 and the top board 1 and the bottom board 2, and ensure a stable connection between the three.

[0058] The serrated pattern 311 on the surface of the middle plate 3 can be mass-produced by a milling machine. The process is mature, simple, and low-cost.

[0059] In some embodiments, the rough structure 31 consists of a plurality of raised particles disposed on the surface of the middle plate 3.

[0060] Please see Figure 1 and Figure 3 In this embodiment, both the top plate 1 and the bottom plate 2 are provided with an arc-shaped surface 4 on one side.

[0061] The curved surface 4 refers to the smooth curved surface formed by grinding, milling and other processing methods on the same side (the side facing the user after the decorative part is installed) of the top plate 1 and the bottom plate 2. The radius of curvature of the curved surface 4 can be set according to the decorative style requirements.

[0062] The curved surface features soft and smooth lines that can coordinate with most interior design styles, enhancing the overall aesthetics and design sense of the decorative piece and avoiding the harshness of right-angled edges.

[0063] Compared with the prior art, this utility model accommodates the wooden middle board 3 in the first accommodating groove 11 and the second accommodating groove 21, so that the top plate 1, the middle board 3 and the bottom plate 2 form a whole, which improves the overall rigidity and bending resistance of the decorative part and ensures that the decorative part is not prone to interlayer separation or deformation due to external force. At the same time, it solves the problem that the traditional aluminum interlayer thickness adjustment is limited and the inconsistent thermal expansion and contraction of metal and wood materials leads to easy deformation and cracking of the decorative part.

[0064] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
