A cellular support structure panel

Abstract

This invention proposes a honeycomb support structure panel, including a panel, a honeycomb sandwich layer, and a back panel, with the honeycomb sandwich layer fixedly connected to the bottom of the panel. The advantages of this invention are: epoxy resin filler is injected into the openings, through-holes, and pre-drilled holes through the panel openings. The pre-drilled holes are angled, allowing the filler to flow smoothly into these holes, forming mechanically interlocking anchor points, greatly enhancing the bonding force between the honeycomb sandwich layer and the panel and back panel. Precise four-corner positioning of the honeycomb sandwich layer using positioning angles ensures accurate alignment of the through-holes with the pre-drilled holes in the back panel and the openings in the panel. Under the action of the angled pre-drilled holes, the filler forms mechanically interlocking anchor points, significantly enhancing the bonding force between the honeycomb sandwich layer and the panel and back panel, making the entire panel structure more stable, able to withstand greater external forces, effectively preventing separation and loosening between layers, and improving the safety and reliability of the structure.

Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel technology, and in particular to a honeycomb support structure panel. Background Technology

[0002] As a lightweight and high-strength composite material, honeycomb supported structural panels are widely used in aerospace, transportation, architectural decoration, electronic equipment and other fields due to their excellent specific strength and specific stiffness. Traditional honeycomb panels are usually made of a top panel, a honeycomb core layer and a bottom back panel bonded together with adhesives, and their structural stability mainly depends on the bonding strength of the adhesive.

[0003] However, in practical applications, this single adhesive bonding method has significant limitations. If the board is exposed to high temperature and humidity for a long time, the adhesive layer is prone to aging, creep, or fatigue damage, leading to a decrease in the interfacial bonding force between the face panel, back panel, and honeycomb core layer, and even delamination and detachment, seriously affecting the safety and service life of the structure. Therefore, a honeycomb support structure panel is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a honeycomb support structure panel to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a honeycomb support structure panel, including a panel, a honeycomb sandwich layer, and a back panel. The honeycomb sandwich layer is fixedly connected to the bottom of the panel, the honeycomb sandwich layer has a plurality of honeycomb cells, and the back panel is fixedly connected to the bottom of the honeycomb sandwich layer.

[0007] The panel has several openings, the honeycomb sandwich layer has several points on its wall with through holes, and the top surface of the back panel has several reserved holes, which are angled.

[0008] The upper port of the through hole is aligned with the opening, and the lower port of the through hole is aligned with the top of the reserved hole;

[0009] Positioning corners are fixedly connected to the four corners of the top surface of the back panel, and the sides of the positioning corners abut against the four corners of the sides of the honeycomb sandwich layer.

[0010] The edges between the panel and the back panel are fixedly connected with edge sealing, and the openings, through holes and reserved holes are filled with a filling layer.

[0011] This honeycomb support structure panel mainly consists of three layers: a face panel, a honeycomb core layer, and a back panel. The positioning angles play a crucial role in the installation process, positioning the honeycomb core layer at its four corners to ensure accurate alignment between the through holes on the honeycomb core layer walls and the pre-drilled holes on the top surface of the back panel and the openings on the face panel.

[0012] During device assembly, a honeycomb sandwich layer is fixedly connected to the bottom of the panel, and a back plate is fixedly connected to the bottom of the honeycomb sandwich layer. Then, edge sealing is installed at the edges between the panel and the back plate. Because the panel has several openings, the honeycomb sandwich layer has several through holes at several points on its wall, and the back plate has several angled pre-drilled holes on its top surface, with the upper ends of the through holes aligned with the openings and the lower ends aligned with the tops of the pre-drilled holes, epoxy resin filler is injected into the openings, through holes, and pre-drilled holes through the openings in the panel after the honeycomb sandwich layer is bonded. The angled pre-drilled holes allow the filler to flow smoothly into these holes, forming mechanically interlocking anchor points. This greatly enhances the bonding force between the honeycomb sandwich layer and the panel and back plate, making the entire panel structure more robust and stable.

[0013] Preferably, the material of the panel and the back panel is PC, and the thickness of the panel is less than the thickness of the back panel.

[0014] The above technical solution is adopted: This device is a honeycomb support structure panel, which consists of three layers: a face panel, a honeycomb sandwich layer, and a back panel. After the panels are assembled, an edge seal is installed between the face panel and the back panel.

[0015] The positioning angles are used to position the honeycomb sandwich layer at its four corners during installation, aligning its through holes with the reserved holes in the back panel and the openings in the front panel.

[0016] Preferably, in any of the above embodiments, the panel and the honeycomb sandwich layer are bonded together with adhesive, and the back panel and the honeycomb sandwich layer are bonded together with adhesive.

[0017] Preferably, in any of the above embodiments, the honeycomb core layer is made of PE and is located inside the edge sealing. Precise four-corner positioning of the honeycomb core layer using positioning angles ensures accurate alignment of the through holes with the pre-drilled holes in the back panel and the openings in the front panel. After injecting epoxy resin filler, the filler forms mechanically interlocking anchor points under the action of the angled pre-drilled holes, significantly enhancing the bonding force between the honeycomb core layer and the front and back panels. This makes the entire panel structure more stable, capable of withstanding greater external forces, effectively preventing separation and loosening between layers, and improving the safety and reliability of the structure.

[0018] Preferably, the positioning angle is bonded to the back plate, as described in any of the above solutions.

[0019] Preferably, in any of the above solutions, the edge banding is bonded to both the panel and the back panel, the edge banding is made of PVC, and the filler layer is made of epoxy resin.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0021] During assembly, the honeycomb support structure panel has a honeycomb core layer fixedly connected to the bottom of the panel, and a back plate fixedly connected to the bottom of the honeycomb core layer. Edge sealing is then installed at the edges between the panel and the back plate. The panel has several openings, the honeycomb core layer has through holes at several points on its walls, and the back plate has several angled pre-drilled holes on its top surface. The upper ends of the through holes are aligned with the openings, and the lower ends are aligned with the tops of the pre-drilled holes. After the honeycomb core layer is bonded, epoxy resin filler is injected into the openings, through holes, and pre-drilled holes through the panel openings. The angled pre-drilled holes allow the filler to flow smoothly into these openings, forming mechanically interlocking anchor points. This greatly enhances the bonding force between the honeycomb core layer and the panel and back plate, making the entire panel structure more robust and stable. Precise four-corner positioning of the honeycomb core layer using positioning angles ensures accurate alignment of the through holes with the pre-drilled holes in the back plate and the openings in the panel. After the epoxy resin filler is injected, the filler forms mechanically interlocked anchor points under the action of the angled reserved holes, which significantly enhances the bonding force between the honeycomb sandwich layer and the panel and back panel, making the entire panel structure more stable and able to withstand greater external forces. This effectively avoids separation and loosening between the layers and improves the safety and reliability of the structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1-4 As shown, this honeycomb support structure panel includes a panel 1, a honeycomb sandwich layer 2, and a back panel 3. The honeycomb sandwich layer 2 is fixedly connected to the bottom of the panel 1. The honeycomb sandwich layer 2 has a number of honeycomb cells. The back panel 3 is fixedly connected to the bottom of the honeycomb sandwich layer 2. The honeycomb sandwich layer 2 is bonded to the panel 1 and the back panel 3 with adhesive. The top and bottom surfaces of the honeycomb sandwich layer 2 are coated with a layer of adhesive and then bonded to the panel 1 and the back panel 3.

[0032] The panel 1 has several openings 4, the honeycomb sandwich layer 2 has several points on the wall with through holes 5, and the back panel 3 has several reserved holes 6 on the top surface. The reserved holes 6 are obliquely opened.

[0033] The upper end of the through hole 5 is aligned with the opening 4, and the lower end of the through hole 5 is aligned with the top of the reserved hole 6;

[0034] Positioning corners 7 are fixedly connected to the four corners of the top surface of the back panel 3, and the sides of the positioning corners 7 abut against the four corners of the sides of the honeycomb sandwich layer 2.

[0035] An edge seal 8 is fixedly connected at the edge between panel 1 and back panel 3, and the opening 4, through hole 5, and reserved hole 6 are filled with a filler layer 9.

[0036] Example 1: The panel 1 and back panel 3 are made of PC, and the thickness of panel 1 is less than the thickness of back panel 3. Panel 1 and honeycomb sandwich layer 2 are bonded together with adhesive, and back panel 3 and honeycomb sandwich layer 2 are also bonded together with adhesive. The honeycomb sandwich layer 2 is made of PE and is located inside the edge sealing layer 8. The positioning corner 7 is bonded to back panel 3. The edge sealing layer 8 is bonded to both panel 1 and back panel 3, and is made of PVC. The filling layer 9 is made of epoxy resin.

[0037] Example 2: This device is a honeycomb support structure panel, which consists of three layers: panel 1, honeycomb core layer 2, and back panel 3. After the panels are assembled, an edge seal 8 is installed between panel 1 and back panel 3.

[0038] The positioning angle 7 serves to position the honeycomb sandwich layer 2 at its four corners during installation, ensuring that its through holes 5 are aligned with the reserved holes 6 on the back panel 3 and the openings 4 on the panel 1. This honeycomb support structure mainly consists of three layers: panel 1, honeycomb sandwich layer 2, and back panel 3. The positioning angle 7 plays a crucial role in the installation process, positioning the honeycomb sandwich layer 2 at its four corners to ensure accurate alignment of the through holes 5 on the wall of the honeycomb sandwich layer 2 with the reserved holes 6 on the top surface of the back panel 3 and the openings 4 on the panel 1.

[0039] During device assembly, a honeycomb sandwich layer 2 is fixedly connected to the bottom of panel 1, and a back plate 3 is fixedly connected to the bottom of honeycomb sandwich layer 2. Then, an edge seal 8 is installed at the edge between panel 1 and back plate 3. Since panel 1 has several openings 4, and honeycomb sandwich layer 2 has several through holes 5 at several points on its wall, and the top surface of back plate 3 has several obliquely opened reserved holes 6, with the upper end of the through hole 5 aligned with the opening 4 and the lower end aligned with the top of the reserved hole 6, after the honeycomb sandwich layer 2 is bonded, epoxy resin filler is injected into the openings 4, through holes 5, and reserved holes 6 through the openings 4 of panel 1. The reserved holes 6 are obliquely opened, allowing the filler to flow smoothly into these holes. After the filler cures, it forms a columnar connector that connects honeycomb sandwich layer 2, back plate 3, and panel 1, forming a mechanically interlocked anchor point. This greatly enhances the bonding force between honeycomb sandwich layer 2 and panel 1 and back plate 3, making the entire panel structure more robust and stable.

[0040] The working principle of this utility model is as follows:

[0041] Material Preparation: PC material is used to make the panel 1 and back panel 3, with panel 1 being thinner than back panel 3; PE material is used to make the honeycomb sandwich layer 2; PVC material is used for the edge banding 8; epoxy resin is used as the filler for the filler layer 9; adhesive and positioning corners 7 are prepared. Several openings 4 are made on panel 1 according to the design requirements. Through holes 5 are made at several points on the wall of the honeycomb sandwich layer 2. Several angled pre-drilled holes 6 are made on the top surface of back panel 3. Four positioning corners 7 are made, ensuring their dimensions accurately abut the four corners of the sides of the honeycomb sandwich layer 2. First, the positioning corners 7 are glued to the four corners of the top surface of back panel 3. Next, the honeycomb sandwich layer 2 is glued to back panel 3. The positioning corners 7 ensure the honeycomb sandwich layer 2 is accurately positioned, ensuring the lower end of the through hole 5 aligns with the top of the pre-drilled hole 6. Then, panel 1 is glued to the honeycomb sandwich layer 2, ensuring the upper end of the through hole 5 aligns with the opening 4.

[0042] Next, adhesive is used to bond the edge seal 8 at the edge between panel 1 and back panel 3, ensuring that the honeycomb core layer 2 is located inside the edge seal 8. Through the opening 4 of panel 1, epoxy resin filler is slowly injected into the opening 4, through hole 5, and reserved hole 6 using special equipment until the filler fills all the holes, forming stable mechanical interlocking anchor points. After the epoxy resin cures, the entire honeycomb support structure panel is assembled.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] During assembly, the honeycomb support structure panel has a honeycomb core layer 2 fixedly connected to the bottom of the panel 1, and a back plate 3 fixedly connected to the bottom of the honeycomb core layer 2. An edge seal 8 is then installed at the edge between the panel 1 and the back plate 3. The panel 1 has several openings 4, the honeycomb core layer 2 has several through holes 5 at several points on its wall, and the back plate 3 has several angled pre-drilled holes 6 on its top surface. The upper end of the through hole 5 is aligned with the opening 4, and the lower end is aligned with the top of the pre-drilled hole 6. After the honeycomb core layer 2 is bonded, epoxy resin filler is injected into the openings 4, through holes 5, and pre-drilled holes 6 through the openings 4 of the panel 1. The pre-drilled holes 6 are angled, allowing the filler to flow smoothly into these holes, forming mechanically interlocking anchor points. This greatly enhances the bonding force between the honeycomb core layer 2 and the panel 1 and back plate 3, making the entire panel structure more robust and stable. Precise four-corner positioning of the honeycomb sandwich layer 2 by positioning angle 7 ensures accurate alignment of the through hole 5 with the reserved hole 6 of the back panel 3 and the opening 4 of the panel 1. After injecting epoxy resin filler, the filler forms mechanically interlocked anchor points under the action of the angled reserved hole 6, significantly enhancing the bonding force between the honeycomb sandwich layer 2 and the panel 1 and back panel 3, making the entire board structure more stable, able to withstand greater external forces, effectively preventing separation and loosening between layers, and improving the safety and reliability of the structure.
