Description

Technical Field

[0001] This utility model relates to the field of panel technology, and more specifically to a lightweight, high-strength furniture panel. Background Technology

[0002] Existing lightweight high-strength furniture panels include honeycomb panels, which are typically made of two layers of high-strength panels (such as aluminum plates, wood veneers, or fiberboard) sandwiching a honeycomb core material (usually made of paper, aluminum foil, or plastic); they are commonly used in high-end furniture, cabinet doors, office furniture, etc. Existing honeycomb panels are shown in "application number: CN201520078404.2";

[0003] The honeycomb core material of the aforementioned honeycomb panel is generally manufactured by using multiple layers of paper or aluminum foil, which are first coated with adhesive at appropriate positions and then stacked together, and then stretched evenly using a stretching device to produce the material as shown in "Application No.: CN201410823697.2, A Method for Manufacturing Aluminum Honeycomb Core".

[0004] Alternatively, a honeycomb core can be fabricated one by one and then stacked, as described in "Application No.: CN202111597223.7, A honeycomb core and its manufacturing method". In order to improve the strength, a molding die is provided to provide cavities for reinforcing ribs on the layers, thus producing a high-strength honeycomb core.

[0005] The aforementioned "honeycomb core and its manufacturing method" can produce high-strength honeycomb cores, but the manufacturing process is relatively complicated and not economical. Utility Model Content

[0006] The purpose of this utility model is to provide a lightweight, high-strength furniture board to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model proposes a lightweight, high-strength furniture board, including a board shell and a core board inside it;

[0009] The core board is composed of multiple sets of first and second type layers that are stacked and fixed in sequence and alternately;

[0010] The first type of layer is composed of two sets of sheet layers bonded together, and the second type of layer is a set of sheet layers.

[0011] In a preferred embodiment of this utility model, the starting group and the ending group of the multiple sets of sequentially and alternately stacked first and second type layers are both first type layers.

[0012] As a preferred embodiment of this utility model, the core board is provided with multiple sets of through holes.

[0013] As a preferred embodiment of this utility model, the multiple sets of through holes are provided on the bonding end of the first type layer that is bonded to the second type layer, and the through holes penetrate the second type layer when the first type layer and the second type layer are bonded together.

[0014] As a preferred embodiment of this utility model, the method further includes a reinforcing component disposed within the shell to improve its connection and support strength.

[0015] As a preferred technical solution of this utility model, the reinforcing component includes a connecting rod that passes through the through hole to penetrate both sides of the core plate and a rod groove provided on the inner wall of the plate shell, with the rod end portion of the connecting rod extending into the rod groove for fitting and fixing.

[0016] As a preferred embodiment of the present invention, the shell includes two sets of opposing clamping plates and a surrounding plate fixedly attached to its edges, with the core plate centrally attached and fixed between the two sets of clamping plates.

[0017] The beneficial effects of this utility model are as follows:

[0018] By directly and completely bonding two sets of sheets together for the first layer, while retaining the original single set of sheets for the second layer, the core board can be manufactured using existing machinery. Only minor changes to the bonding structure are needed to greatly improve the front-to-back support strength of the core board and also enhance its strength in other directions. This method is simple to manufacture, economical, and results in a high-strength furniture board structure. Attached Figure Description

[0024] like Figures 1-4 As shown, this embodiment proposes a lightweight, high-strength furniture board, comprising a shell 1 and a core board 2 disposed therein;

[0025] The panel 1 includes two sets of opposing clamps 11 and a surrounding panel 12 that is attached and fixed along its edge. The core board 2 is centrally attached and fixed between the two sets of clamps 11. The two sets of clamps 11 are arranged front and back and the core board 2 is fixed between the two sets of clamps 11 by means of glue or the like. Four sets of surrounding panels 12 are used to attach and fix the edges around the clamps 11. This is how the furniture panel is made.

[0026] The core board 2 is composed of multiple sets of first type layers 21 and second type layers 22 that are stacked and fixed in sequence. The core board 2 (i.e., the honeycomb core) is manufactured using a traditional method similar to "CN201410823697.2" in the background art, which is more economical and the technology is mature.

[0027] The first type layer 21 is composed of two sets of sheet layers bonded together, and the second type layer 22 is a set of sheet layers. The sheet material is existing paper or aluminum foil. Now, by making the first type layer 21 by directly and completely bonding two sets of sheet materials together, while the second type layer 22 is still retained as a set of sheet layers, the original mechanical equipment can still be used when making the core board 2. Only a slight change is needed in the bonding structure, which can greatly improve the support strength of the core board 2 in the front and rear directions and the strength in other directions can also be improved. The manufacturing is simple and economical.

[0028] In this context, the starting and ending groups of multiple sets of sequentially and alternately stacked and fixed first-type layers 21 and second-type layers 22 are both first-type layers 21; for example... Figure 3 As shown, the first type layer 21 and the second type layer 22 are arranged alternately from left to right. When the first type layer 21 is at the beginning and the second end of the arrangement, the high strength of the first type layer 21 can balance the support strength at the left and right ends. Example 2:

[0029] like Figures 1-4 As shown, the difference between it and embodiment 1 is that: it also includes multiple sets of through holes 3 on the core plate 2. When the core plate 2 is used to bond the clamping plate 11, it needs to be hot-pressed to improve the connection strength. At this time, pressure will be generated in the core cavity of the core plate 2, and the through holes 3 can be used as pressure relief holes; and it can also save materials.

[0030] Among them, multiple sets of through holes 3 are provided on the bonding end of the first type layer 21 that is bonded to the second type layer 22. When the first type layer 21 and the second type layer 22 are bonded, the through holes 3 penetrate the second type layer 22. This is because when the first type layer 21 and the second type layer 22 are made into the core board 2, the first type layer 21 and the second type layer 22 have separate supports and support parts after bonding. That is, the strength of the support parts after bonding must be greater. Therefore, making holes at the bonding position is reasonable for preserving the structural strength. Example 3:

[0031] like Figures 1-4 As shown, the difference between this embodiment and embodiment 2 is that it also includes a reinforcing component 4 disposed inside the shell 1 to improve its connection and support strength, thereby improving the structural strength of the plate when in use.

[0032] The specific structure of the reinforcement component 4 is shown below:

[0033] The reinforcing component 4 includes a connecting rod 41 that passes through the through hole 3 to penetrate both sides of the core plate 2 and a rod groove 42 provided on the inner wall of the plate shell 1. The rod end portion of the connecting rod 41 extends into the rod groove 42 and is fixed in place.

[0034] like Figure 2 , 4 As shown, through the pre-set through holes 3 on the core plate 2, rod grooves 42 are pre-set inside the shell 1 (as shown in the figure, the surrounding plate 12 at the left and right positions). The connecting rod 41 passes through multiple through holes 3 simultaneously to pass through the core plate 2 to the left and right without occupying space. Both ends of the connecting rod 41 are placed into the rod grooves 42 and can be glued together to strengthen the connection strength of the shell 1 and the support strength at the left and right positions. In addition, the reinforcing components 4 are set in two sets, one above the other, which can further improve the structural strength.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
