The plastic base layer is provided with grooves corresponding to the protrusions, and the protrusions are located in the grooves. The aluminum surface layer and the plastic base layer are fixedly bonded by adhesive."

[0003] Therefore, the above utility model patents have disclosed one technical solution for a multi-layer composite decorative panel structure. However, the technical solution disclosed in the above utility model patents focuses on fixing the connecting blocks by reinforcing aluminum strips to achieve a more stable structure, but does not further solve the problems of misaligned distribution of the unit gaps during stacking, thus failing to enhance the overall structural stability and impact resistance. Further improvements are needed. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a multi-layer composite decorative panel structure.

[0005] This utility model adopts the following technical solution: a multi-layer composite decorative panel structure, including a top sheet, a bottom sheet, and a decorative panel assembly, wherein:

[0006] The decorative panel assembly is located between the top panel and the bottom panel, and the decorative panel assembly includes at least two decorative panels;

[0007] Decorative panels are stacked and distributed, with adjacent decorative panels bonded together, decorative panels bonded to the top panel, and decorative panels bonded to the bottom panel.

[0008] The decorative panel includes a first panel, a second panel, a third panel, and a fourth panel that are arranged sequentially and adjacent to each other. The fourth panel has multiple adjacent and integrally formed fourth panel elements.

[0009] As a preferred technical solution of the above technical solutions, the fourth plate element has a protruding part, a base part and two vertical parts. One end of the vertical part of one element is integrally formed with the protruding part, and the other end of the vertical part is integrally formed with one end of the base part. The other vertical part of the other element is integrally formed with the other end of the base part, and the other end of the vertical part is integrally formed with the protruding part of the adjacent fourth plate element.

[0010] As a preferred technical solution to the above technical solutions, the hypotenuse length of the vertical part of the fourth plate element decreases sequentially.

[0011] As a preferred technical solution to the above technical solutions, the top plate is provided with a narrow top plate portion and a wide top plate portion fixedly connected to the narrow top plate portion.

[0012] As a preferred technical solution to the above technical solutions, the film has a narrow film portion and a wide film portion fixedly connected to the narrow film portion.

[0013] The multi-layer composite decorative panel structure disclosed in this utility model has the following advantages: each decorative panel has multiple integrally formed fourth panel elements in its fourth panel body. The gaps between these elements are staggered during stacking, effectively enhancing the stability and impact resistance of the overall structure and preventing deformation or cracking caused by stress concentration. Simultaneously, the concave and convex structures of the fourth panel elements (such as protruding parts, bases, and vertical parts) are formed by pressing fiberboard, simplifying the manufacturing process and reducing costs. Furthermore, the arithmetic progression design of the decreasing hypotenuse length of the vertical parts ensures that the fourth panel body's top view projection is an equilateral right-angled triangle, facilitating precise combination with other panels such as the third panel body, thus improving installation efficiency and decorative aesthetics.

Detailed Implementation

[0023] This utility model discloses a multi-layer composite decorative panel structure. The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0024] See attached diagram. Figures 1 to 8 , Figures 1 to 4 The multi-layered composite decorative panel structure is shown from different perspectives. Figure 5 and Figure 6 The decorative panel assembly is shown from different perspectives. Figure 7 and Figure 8 The decorative panels are shown from different perspectives.

[0025] Example 1.

[0026] Preferably, the multi-layer composite decorative panel structure includes a top sheet 100, a bottom sheet 200, and a decorative panel assembly 300, wherein:

[0027] The decorative panel assembly 300 is located between the top panel 100 and the bottom panel 200, and the decorative panel assembly 300 includes at least two decorative panels 400;

[0028] The decorative panels 400 are stacked and distributed, with adjacent decorative panels 400 bonded together. The top decorative panel 400 is bonded to the top piece 100, and the bottom decorative panel 400 is bonded to the bottom piece 200.

[0029] Decorative panel 400 includes a first panel 410, a second panel 420, a third panel 430, and a fourth panel 440 that are sequentially distributed and adjacent to each other. The fourth panel 440 is provided with a plurality of adjacent and integrally formed fourth panel elements 441 (see reference). Figure 8The red virtual dividing line indicates that the fourth plate 440 can be virtually divided into multiple adjacent and integrally formed fourth plate basic elements 441. The fourth plate basic elements 441 have basic element gaps 445. This means that when the decorative panels 400 are stacked, the basic element gaps 445 of the upper decorative panel 400 may not be directly opposite to the basic element gaps 445 of the lower decorative panel 400, which is equivalent to the basic element gaps 445 of two adjacent decorative panels 400 being misaligned.

[0030] Among them, reference Figure 8 The fourth plate element 441 is provided with an element protrusion 442, an element base 444, and two element vertical parts 443. One end of the element vertical part 443 is integrally formed with the element protrusion 442, and the other end of the element vertical part 443 is integrally formed with one end of the element base 444. The other end of the element vertical part 443 is integrally formed with the other end of the element base 444, and the other end of the element vertical part 443 is integrally formed with the element protrusion 442 of the adjacent fourth plate element 441. Thus, the fourth plate element 441 serves as the basic unit of the fourth plate 440, and the fourth plate 440 can be constructed into a concave-convex structure composed of multiple fourth plate elements 441.

[0031] Among them, reference Figure 7 The length of the hypotenuse of the vertical part 443 of the fourth plate element 441 decreases sequentially (preferably in an arithmetic progression); so that the top view of the fourth plate 440 is projected as an equilateral right triangle, which facilitates its combination and distribution with other plates such as the third plate 430 and to form a decorative plate 400.

[0032] Among them, reference Figure 4 The top plate 100 is provided with a narrow top plate portion 110 and a wide top plate portion 120 fixedly connected to the narrow top plate portion 110.

[0033] Among them, reference Figure 4 The film 200 has a narrow film portion 210 and a wide film portion 220 fixedly connected to the narrow film portion 210.

[0034] The fourth plate 440 is preferably formed by pressing fiberboard; this facilitates the pressing to form a concave-convex structure composed of multiple fourth plate basic units 441.

[0035] Similar to the concave-convex structure of the fourth plate 440, the third plate 430, the second plate 420, and the first plate 410 are each provided with multiple adjacent and integrally formed basic elements, which will not be described in detail here.

[0036] It is worth mentioning that the specific components and other technical features of the fiberboard involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement methods of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0037] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
