Composite honeycomb panel and storage cabinet

Abstract

This utility model relates to the field of honeycomb panel technology, and discloses a composite honeycomb panel and a storage cabinet. The composite honeycomb panel has a thickness direction and includes multiple layers and multiple honeycomb cores. Each layer includes two outer layers and multiple inner layers, with the outer and inner layers spaced apart in the thickness direction, and the inner layers located between the two outer layers. The honeycomb cores are respectively disposed between two adjacent layers. On one hand, the composite honeycomb panel has inner layers, allowing fasteners inserted into the panel to connect to at least the nearest inner layer, thereby improving the holding power of the composite honeycomb panel. On the other hand, the composite honeycomb panel uses multiple honeycomb cores instead of the original single honeycomb core, reducing the thickness of each individual core and correspondingly increasing its mechanical strength. This makes the honeycomb core less prone to deformation and friction during movement, thus reducing the risk of abnormal noise from the composite honeycomb panel.

Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel technology, specifically to composite honeycomb panels and storage cabinets. Background Technology

[0002] Storage cabinets installed in bathrooms require high waterproof and moisture-proof performance. Traditional composite boards contain wood, which can lead to localized mold growth if used in bathrooms for extended periods.

[0003] Therefore, metal composite panels are often used in related technologies to assemble bathroom storage cabinets. For example, metal composite panels can be made of honeycomb aluminum filled inside, which can make the storage cabinets lightweight while being waterproof and moisture-proof.

[0004] However, due to the inner structure being made of honeycomb aluminum, honeycomb panels generally suffer from insufficient nail-holding power, especially the door panels of storage cabinets. After repeated opening and closing, the fasteners (such as screws, rivets, and rivet nuts) connecting the hinges and the door panels are prone to loosening, causing the hinges to detach from the door panels. Furthermore, during the opening and closing process, the internal honeycomb aluminum is prone to deformation and mutual friction, producing abnormal noises and affecting the user experience. Utility Model Content

[0005] In view of this, the present invention provides a composite honeycomb panel and a storage cabinet to solve the problems of insufficient nail holding power and easy noise generation of honeycomb panels.

[0006] In a first aspect, the present invention provides a composite honeycomb panel having a thickness direction, the composite honeycomb panel comprising multiple layers and multiple honeycomb cores, each layer comprising two outer layers and multiple inner layers, the outer layers and the inner layers being arranged at intervals in the thickness direction, and the inner layers being located between two outer layers, and the honeycomb cores being respectively disposed between two adjacent layers.

[0007] Beneficial effects: On the one hand, the composite honeycomb panel has an inner layer, and the fasteners inserted into the composite honeycomb panel can be connected to at least the nearest inner layer, thereby improving the holding force of the composite honeycomb panel; on the other hand, by setting an inner layer, the composite honeycomb panel uses multiple honeycomb cores instead of the original whole honeycomb core, which reduces the thickness of a single honeycomb core and correspondingly improves the mechanical strength of the honeycomb core. This makes the honeycomb core less prone to deformation and friction when the composite honeycomb panel moves, thereby reducing the risk of abnormal noise from the composite honeycomb panel.

[0008] In one alternative embodiment, the thickness of the inner plate layer is between 0.1 mm and 0.4 mm.

[0009] Beneficial effects: By limiting the minimum thickness of the inner panel, the mechanical strength of the inner panel can be guaranteed to meet the requirements, making it less likely to deform or even break under the tension of fasteners, and providing sufficient holding force for fasteners; by limiting the maximum thickness of the inner panel, the mass of the inner panel can be avoided to prevent it from being too large, thereby ensuring the lightweight of the composite honeycomb panel.

[0010] In one alternative embodiment, the outer panel layer is thicker than the inner panel layer, and the thickness of the outer panel layer is between 0.4 mm and 1.2 mm.

[0011] Beneficial effects: Using a relatively thick outer layer can improve the outer layer's ability to resist external impacts and collisions, which helps to reduce the surface deformation of the composite honeycomb panel after being hit, maintain the aesthetics of the composite honeycomb panel, and improve the user experience.

[0012] In one optional embodiment, the honeycomb core comprises a first honeycomb core and a second honeycomb core, the first honeycomb core being disposed between the outer plate layer and the inner plate layer, the second honeycomb core being disposed between the two inner plate layers, and the thickness of the first honeycomb core being less than that of the second honeycomb core.

[0013] Beneficial effects: Using a relatively thinner first honeycomb core can shorten the distance between the outer and inner layers. On the one hand, this facilitates the use of shorter fasteners to connect the composite honeycomb panels and the external structure, reducing component costs. On the other hand, it can further improve the deformation resistance of the first honeycomb core, enhance screw holding force, and reduce the risk of abnormal noise.

[0014] In one alternative embodiment, the honeycomb core includes a honeycomb structure with a side length less than or equal to 3 mm.

[0015] Beneficial effects: By using a relatively smaller honeycomb structure, the density of the honeycomb core can be increased, enhancing the mechanical strength and deformation resistance of the honeycomb core, thereby further improving the nail-holding force of the composite honeycomb panel and reducing the risk of abnormal noise.

[0016] In one alternative embodiment, an adhesive layer is further included, which bonds the honeycomb core and the panel layer.

[0017] Beneficial effects: By setting an adhesive layer, the composite honeycomb panels are tightly bonded by applying adhesive and pressing, which can prevent loosening and displacement between the panels and the honeycomb core, improve the bonding reliability of the composite honeycomb panels, and reduce the risk of abnormal noise caused by loosening.

[0018] In one alternative embodiment, an edge sealing strip is also included, which covers the side surfaces of the board layer and the honeycomb core.

[0019] Beneficial effects: The edge banding covers the honeycomb core, which can prevent foreign objects from falling into the honeycomb core, reduce the risk of abnormal noise caused by foreign objects hitting the honeycomb core, and the edge banding also makes the side of the composite honeycomb panel more aesthetically pleasing.

[0020] In an alternative embodiment, a finishing layer is further included, the finishing layer being disposed on the side of the outer panel layer opposite to the inner panel layer.

[0021] Beneficial effects: The finishing layer has a decorative effect, making the outer surface of the composite honeycomb panel more beautiful and improving the user experience.

[0022] In one alternative embodiment, the material of the plate layer and the honeycomb core is aluminum.

[0023] Beneficial effects: Using aluminum as the material for the layers and the honeycomb core can reduce the weight of the composite honeycomb panel while ensuring mechanical strength, which is beneficial for the lightweight design of the composite honeycomb panel.

[0024] Secondly, this utility model also provides a storage cabinet, including a door panel, wherein the door panel includes the composite honeycomb material provided by this utility model.

[0025] The locker includes the composite honeycomb panel provided by this utility model, and therefore has the beneficial effects brought by the composite honeycomb panel, which will not be elaborated here. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0034] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this utility model, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0036] Bathroom storage cabinets are widely used in interior design. Storage cabinets placed in bathrooms require high levels of waterproofing and moisture resistance, therefore, cabinets with an outer panel are generally used. Early technologies typically used stainless steel / aluminum panels processed with bending techniques, with the interior filled with materials such as honeycomb aluminum, wood strips, or PVC. This process was prone to problems such as inner layer displacement, surface dents, and localized mold growth.

[0037] In some current related technologies, metal composite panels are often used to assemble bathroom storage cabinets. The interior of the metal composite panel is made of metal material (for example, the interior is filled with honeycomb core 102) to achieve waterproof and moisture-proof effects and meet the usage needs of bathroom space.

[0038] However, due to the honeycomb core 102 inner structure, the board generally has insufficient nail-holding power, especially the door panel of the storage cabinet. The door panel is connected to the cabinet body by hinges, and the hinges are fixed to the door panel by fasteners (such as screws, rivets, and rivet nuts). After repeated opening and closing of the door panel, the fasteners are easy to loosen, causing the hinge to detach from the door panel. In addition, holes need to be drilled at the connection point to install the hinge, which damages the structural integrity of the honeycomb core 102. During the opening and closing process, the remaining honeycomb core 102 is easy to deform and rub against each other, producing abnormal noise and affecting the user experience.

[0039] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0040] Reference Figure 1 , Figure 2According to an embodiment of the present invention, a composite honeycomb panel 1 is provided. The composite honeycomb panel 1 has a thickness direction and includes multiple layers and multiple honeycomb cores 102. Each layer includes two outer layers 1011 and multiple inner layers 1012. The outer layers 1011 and the inner layers 1012 are arranged at intervals in the thickness direction, and the inner layers 1012 are located between the two outer layers 1011. The honeycomb cores 102 are respectively disposed between two adjacent layers.

[0041] On the one hand, the composite honeycomb panel 1 has an inner layer 1012, and the fasteners inserted into the composite honeycomb panel 1 can be connected to at least the nearest inner layer 1012. The inner layer 1012 distributes the tensile force of the fastener to the honeycomb core 102, so that the honeycomb core 102 can provide support for the fastener, thereby improving the holding force of the composite honeycomb panel 1.

[0042] On the other hand, by setting the inner plate layer 1012, the composite honeycomb panel 1 uses multiple honeycomb cores 102 to replace the original whole honeycomb core 102, which reduces the thickness of a single honeycomb core 102 and correspondingly improves the mechanical strength of the honeycomb core 102. While improving the nail holding force, it also makes the honeycomb core 102 less prone to deformation and friction when the composite honeycomb panel 1 moves, thereby reducing the risk of abnormal noise in the composite honeycomb panel 1.

[0043] Furthermore, in practical applications, fasteners can be flexibly selected as needed to connect the fasteners to some or all of the inner layers 1012 of the composite honeycomb panel 1. For example, when a relatively greater holding force is required, a relatively long fastener can be used to connect multiple inner layers 1012 simultaneously; when the required holding force is relatively small, a relatively short fastener can be used to connect only one inner layer 1012, thereby reducing component costs.

[0044] Optionally, in some embodiments, the outer layer 1011 is thicker than the inner layer 1012. Using a relatively thicker outer layer 1011 can improve the outer layer 1011's ability to resist external impacts and collisions, which helps to reduce the surface deformation of the composite honeycomb panel 1 after being impacted, maintain the aesthetics of the composite honeycomb panel 1, and improve the user experience.

[0045] For example, in some embodiments, the thickness of the inner layer 1012 is between 0.1 mm and 0.4 mm. By limiting the minimum thickness of the inner layer 1012, the mechanical strength of the inner layer 1012 can be ensured to meet the requirements, making it less prone to deformation or even breakage under the tension of fasteners, and providing sufficient holding force for the fasteners; by limiting the maximum thickness of the inner layer 1012, excessive mass of the inner layer 1012 can be avoided, thereby ensuring the lightweight of the composite honeycomb panel 1. For example, in some embodiments, the thickness of the outer layer 1011 is between 0.4 mm and 1.2 mm.

[0046] Preferably, in some embodiments, the thickness of the inner plate layer 1012 is between 0.15 mm and 0.25 mm, and the thickness of the outer plate layer 1011 is between 0.55 mm and 0.65 mm.

[0047] Optionally, in some embodiments, the honeycomb core 102 includes a first honeycomb core 1021 and a second honeycomb core 1022. The first honeycomb core 1021 is disposed between the outer plate layer 1011 and the inner plate layer 1012, and the second honeycomb core 1022 is disposed between the two inner plate layers 1012. The thickness of the first honeycomb core 1021 is less than that of the second honeycomb core 1022.

[0048] Using a relatively thin first honeycomb core 1021 can shorten the distance between the outer layer 1011 and the inner layer 1012. On the one hand, this is beneficial to use shorter fasteners to complete the connection between the composite honeycomb panel 1 and the external structure, reducing the cost of parts. On the other hand, it can further improve the deformation resistance of the first honeycomb core 1021, enhance the screw holding force, and reduce the risk of abnormal noise.

[0049] It is understood that the number of inner layer 1012 can be two or more, and therefore the number of second honeycomb cores 1022 can be one or more. For example, an upper limit can be set for the thickness of a single second honeycomb core 1022, so that the total number of second honeycomb cores 1022 can be flexibly determined according to the overall thickness of the composite honeycomb panel 1. By limiting the upper limit of thickness, it is possible to avoid insufficient mechanical strength and deformation resistance of the second honeycomb core 1022 due to excessive thickness, which helps to reduce the risk of abnormal noise.

[0050] To ensure sufficient strength of the honeycomb core 102, in addition to limiting its thickness, other parameters of the honeycomb core 102 can be limited in some embodiments. For example, in some embodiments, the side length of the honeycomb structure of the honeycomb core 102 is equal to 3 mm. In other words, the honeycomb core 102 uses an A3*3 specification. By using a relatively smaller honeycomb structure, the arrangement density of the honeycomb core 102 can be increased, enhancing its mechanical strength and resistance to deformation, thereby further improving the nail-holding force of the composite honeycomb panel 1 and reducing the risk of abnormal noise.

[0051] Furthermore, the side length of the honeycomb structure can also be less than 3mm.

[0052] Alternatively, the wall thickness of the honeycomb structure can be limited, for example, the wall thickness can be limited to greater than or equal to 0.038 mm.

[0053] Optionally, in some embodiments, the composite honeycomb panel 1 further includes an adhesive layer, which bonds the honeycomb core 102 and the panel layers. It is understood that, in addition to noise caused by deformation of the honeycomb core 102, noise may also originate from structural loosening of the composite honeycomb panel 1, causing displacement and scraping between the honeycomb core 102 and the panel layers during opening and closing. By providing an adhesive layer, the composite honeycomb panel 1 is tightly bonded through adhesive application and pressing, preventing loosening and displacement between the panel layers and the honeycomb core 102, improving the bonding strength of the composite honeycomb panel 1, and reducing the risk of noise caused by loosening.

[0054] by Figure 2 Taking the composite honeycomb panel 1 with two inner layers 1012 as an example, the process involves first applying adhesive and stacking the panels, followed by pressing them together in a press. Specifically, adhesive is first applied to the surface of one outer layer 1011, and then the honeycomb core 102 is laid on the surface after adhesive application. Next, adhesive is applied to both sides of one inner layer 1012, and then it is placed on the surface of the honeycomb core 102, and the honeycomb core 102 is laid on the surface of the inner layer 1012 again. This process continues with applying adhesive to both sides of the other inner layer 1012, placing it on the surface of the honeycomb core 102, and laying the honeycomb core 102 on the surface of the inner layer 1012 again. Finally, adhesive is applied to the surface of the other outer layer 1011, and then it is placed on the surface of the honeycomb core 102, completing the stacking process.

[0055] The two-sided gluing can be completed using a roller glue machine. Polyurethane glue can be used, with a single-sided gluing amount of 250g to 400g per sheet, preferably 320g to 350g per sheet. The pressing pressure is 25 to 40 tons, preferably 35 tons; the holding time is 6 to 10 hours, preferably 8 hours.

[0056] Optionally, in some embodiments, the composite honeycomb panel 1 further includes an edge sealing strip 104, which covers the side surfaces of the panel layers and the honeycomb core 102. The edge sealing strip 104 covers the honeycomb core 102, which can prevent foreign objects from falling into the honeycomb core 102, reduce the risk of abnormal noise caused by foreign objects hitting the honeycomb core 102, and the edge sealing strip 104 also makes the side of the composite honeycomb panel 1 more aesthetically pleasing.

[0057] Optionally, in some embodiments, the composite honeycomb panel 1 further includes a decorative layer 103, which is disposed on the side of the outer panel layer 1011 opposite to the inner panel layer 1012. The decorative layer 103 serves a decorative purpose, making the outer surface of the composite honeycomb panel 1 more aesthetically pleasing and improving the user experience.

[0058] For example, the finishing layer 103 can be a PVC or PET film.

[0059] The decorative layer 103 can also be bonded to the outer panel layer 1011 by gluing. Specifically, after applying glue, the decorative layer 103 is placed on the outer panel layer 1011 and then pressed together in a press.

[0060] The adhesive used is polyurethane adhesive, with an application amount of 250g to 400g per sheet, preferably 300g to 320g per sheet; the pressing pressure is 25 to 40 tons, preferably 35 tons; the pressing temperature is 150℃ to 180℃, preferably 170℃; and the holding time is 6 to 10 hours, preferably 8 hours.

[0061] It is understandable that the materials of the panels and honeycomb core 102 can be metal materials or other non-wood materials that are not easy to absorb moisture and mold, so as to meet the moisture-proof requirements when the composite honeycomb panel 1 is used in the storage cabinet set in the bathroom space. For example, the materials of the panels and honeycomb core 102 can be aluminum. On the one hand, aluminum has the characteristics of lightweight and low cost, which can reduce the weight of the composite honeycomb panel 1 while ensuring mechanical strength. On the other hand, aluminum has outstanding moisture-proof and rust-proof capabilities, which can better meet the needs of the bathroom space.

[0062] Secondly, referring to Figure 3 The present invention also provides a storage cabinet, including a door panel, the door panel including the composite honeycomb material 1 provided by the present invention.

[0063] The locker includes the composite honeycomb panel 1 provided by this utility model, and therefore has the beneficial effects brought by the composite honeycomb panel 1, which will not be elaborated here.

[0064] In addition to the door panel, other panels in the storage cabinet can also be made of composite honeycomb panels, which makes the entire storage cabinet lightweight and waterproof and moisture-proof.

[0065] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
