Description

Technical Field

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

[0002] Modern cities are filled with high-rise buildings, and elevators are an indispensable tool in these structures. As a core piece of vertical transportation equipment, the safety, energy efficiency, and passenger comfort of elevators have become key concerns in the industry. The elevator car, as a space where passengers directly interact, has its decorative panels whose performance directly impacts user experience, equipment energy consumption, and maintenance costs. Currently, elevator car decorative panels primarily use metal sheets (such as stainless steel and aluminum alloy), and these panels present the following problems in practical applications:

[0003] While metal sheets offer high strength, their high density increases the overall weight of the elevator car, indirectly exacerbating energy consumption during elevator operation. Statistics show that a 10% reduction in car weight can reduce elevator energy consumption by approximately 5%-8%. Furthermore, heavier decorative panels place higher demands on the load-bearing capacity of the elevator traction system, increasing equipment manufacturing costs.

[0004] Furthermore, all-metal car trim panels have significant shortcomings in terms of sound insulation, vibration damping, and thermal resistance. For example, metal sheets easily transmit noise and vibration, resulting in a noisy environment inside the car. While wood has some sound absorption properties, its flammability makes it difficult to meet the fire protection standards for high-rise buildings, and it is also prone to deformation in humid environments. Although plastic substrates (such as PVC) are lightweight, they have drawbacks such as insufficient rigidity.

[0005] In addition, the car trim panels are inevitably damaged during long-term use. The outer surface of the car trim panels is the most vulnerable to damage. Since the current car trim panels are basically one piece, the entire panel needs to be replaced during repair and replacement, resulting in high maintenance costs. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a honeycomb structure car decorative panel to solve the technical problems of the obvious shortcomings in the performance of existing car decorative panels and the large amount of use and maintenance required.

[0007] To achieve the above objectives, this utility model provides a honeycomb structure car decorative panel, including a honeycomb plate as the innermost substrate, wherein the honeycomb plate is provided with a plurality of evenly arranged honeycomb holes, and the car decorative panel further includes:

[0008] A plastic substrate is fixedly connected to the outer surface of the honeycomb panel, and the plastic substrate is provided with several fixing bolts for fixing the car decoration panel;

[0009] A plastic elastic layer fixedly connected to the outer surface of a plastic substrate;

[0010] A metal panel is attached to the outer side of the plastic elastic layer, and the metal panel is fixedly connected to the plastic substrate by a snap-fit ​​assembly.

[0011] Furthermore, the honeycomb panel is made of aluminum-manganese alloy with a thickness of 10-12mm, and the honeycomb holes on the honeycomb panel are regular hexagons.

[0012] Furthermore, the plastic substrate is made of polyvinyl chloride, fluoropolymer, or silicone rubber with a thickness of 3-5 mm, and the plastic elastic layer is made of silicone rubber with a thickness of 5-10 mm.

[0013] Furthermore, the plastic elastic layer is provided with bolt grooves and snap-fit ​​grooves, the fixing bolts are located in the bolt grooves, and the snap-fit ​​components are located in the snap-fit ​​grooves.

[0014] Furthermore, the metal panel is made of stainless steel and has a thickness of 2-3mm.

[0015] Furthermore, the snap-fit ​​assembly includes a snap fastener slidably connected to the outer side of the plastic substrate and a connector fixedly connected to the corresponding position on the inner side of the metal panel, wherein the snap fastener and the connector can engage in a snap-fit ​​manner.

[0016] Furthermore, the buckle assembly is provided in four sets, located at the four corners of the plastic substrate and the metal panel respectively.

[0017] Furthermore, the sliding buckle consists of a cylinder and a circular plate. The inner end of the cylinder is horizontally slidably connected to the outer surface of the plastic substrate, and the circular plate is fixedly connected to the outer end of the cylinder. The connector is provided with a sliding buckle groove.

[0018] Furthermore, the plastic substrate is bonded to the outer surface of the honeycomb panel with epoxy resin adhesive, and the plastic elastic layer is also bonded to the plastic substrate with epoxy resin adhesive.

[0019] The beneficial effects of this utility model are as follows: 1. The car decoration panel is made of a composite board composed of a honeycomb panel, a plastic substrate, a plastic elastic layer, and a metal panel, resulting in superior performance. The honeycomb panel, as the main supporting material, is made of aluminum-manganese alloy and designed in a honeycomb shape to achieve lightweighting while meeting strength requirements. The plastic substrate, as the core connecting plate, connects the other three layers, ensuring the overall stability of the car decoration panel.

[0020] 2. Since the metal panel is the outermost layer and most susceptible to damage, it is designed as a detachable connection, while the other three layers are designed as fixed connections. When the metal panel is damaged, only the metal panel can be replaced, keeping the other three layers intact. This not only reduces usage and maintenance costs but also makes replacement simple and convenient. In addition, the connector between the metal panel and the plastic substrate is located on the inside of the metal panel, ensuring a smooth and flat outer surface of the metal panel.

[0021] 3. The honeycomb design of the honeycomb panel can absorb noise, and the addition of a plastic elastic layer can further absorb noise. At the same time, the plastic elastic layer can also improve the shock absorption and thermal resistance. Moreover, the elasticity of the plastic elastic layer can fill the gap between the metal panel and the plastic substrate, ensuring the overall sealing and stability. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0034] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, traditional elevator car panels have various drawbacks. For example, while metal sheets have high strength, their high density increases the overall weight of the car, and they also have poor heat and sound insulation. Wood, although possessing some sound absorption properties, is flammable and fails to meet the fire safety standards for high-rise buildings, and it is also prone to deformation in humid environments. While plastic substrates are lightweight, they lack rigidity. Therefore, this solution uses composite panels made from various materials as the elevator car panels.

[0035] Specifically, a honeycomb panel 101 is set as the innermost substrate, and a plastic substrate 102 is fixedly connected to the outer surface of the honeycomb panel 101. Several fixing bolts 107 are provided on the plastic substrate 102 for fixing the car trim panel. Then, a plastic elastic layer 103 is fixedly connected to the outer surface of the plastic substrate 102, and finally, a metal panel 104 is attached to the outer surface of the plastic elastic layer 103. To maintain the stability of the metal panel 104, the metal panel 104 and the plastic substrate 102 are fixedly connected by a snap-fit ​​assembly.

[0036] Preferably, the honeycomb plate 101 has a plurality of evenly arranged honeycomb holes, and the honeycomb holes on the honeycomb plate 101 are regular hexagons.

[0037] In addition, the honeycomb panel 101 is made of aluminum-manganese alloy with a thickness of 10-12mm, the plastic substrate 102 is made of polyvinyl chloride, fluoropolymer, or silicone with a thickness of 3-5mm, and the plastic elastic layer 103 is made of silicone rubber with a thickness of 5-10mm. The metal panel 104 is made of stainless steel with a thickness of 2-3mm.

[0038] Preferably, the plastic substrate 102 is bonded to the outer surface of the honeycomb panel 101 with epoxy resin adhesive, and the plastic elastic layer 103 is also bonded to the plastic substrate 102 with epoxy resin adhesive.

[0039] The car interior trim panel is made of a composite panel consisting of a honeycomb panel 101, a plastic substrate 102, a plastic elastic layer 103, and a metal panel 104, resulting in superior performance. The honeycomb panel 101, as the main supporting material, is made of aluminum-manganese alloy and designed in a honeycomb pattern to achieve weight reduction while meeting strength requirements. The plastic substrate 102 serves as the core connecting plate, linking the other three layers and ensuring the overall stability of the car interior trim panel.

[0040] In addition, the honeycomb panel 101 is designed in a honeycomb shape to absorb noise. The addition of a plastic elastic layer 103 can further absorb noise, and the plastic elastic layer 103 can also improve the shock absorption and thermal resistance. Moreover, the plastic elastic layer 103 is elastic and can fill the gap between the metal panel 104 and the plastic substrate 102, ensuring the overall sealing and stability.

[0041] The second aspect of this utility model is as follows: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, car trim panels are inevitably damaged during long-term use, with the outer surface being the most susceptible. Currently, car trim panels are mostly one-piece, requiring the entire panel to be replaced during repairs, resulting in high maintenance costs. Therefore, this embodiment designs the outermost metal panel 104 as a detachable connection. The metal panel 104 and the plastic substrate 102 are fixedly connected by a snap-fit ​​assembly, which can be separated to achieve detachment.

[0042] The snap-fit ​​assembly includes a snap fastener 108 slidably connected to the outer surface of the plastic substrate 102 and a connector 109 fixedly connected to a corresponding position on the inner surface of the metal panel 104. The snap fastener 108 and the connector 109 can engage in a snap-fit ​​manner. The snap fastener 108 consists of a cylinder and a circular plate. The inner end of the cylinder is horizontally slidably connected to the outer surface of the plastic substrate 102, while the circular plate is fixedly connected to the outer end of the cylinder. The connector 109 has a snap fastener slot 110. The snap fastener slot 110 includes a circular groove at the outer end and a locking groove integral with the cylindrical groove, as shown in the attached figure. Figure 7 As shown, the inner diameter of the circular groove is the same as the diameter of the circular plate, while the width of the slot is the same as the diameter of the cylinder.

[0043] Preferably, the snap-fit ​​assembly has four sets, which are located at the four corners of the plastic substrate 102 and the metal panel 104, respectively.

[0044] The sliding buckle 108 can be made of ferrous metal or magnetic material. Therefore, the connection and separation between the sliding buckle 108 and the sliding buckle slot 110 can be operated using an external magnet. In use, the external magnet attracts the sliding buckle 108 through the metal panel 104. Moving the external magnet drives the sliding buckle 108 to slide, thus positioning it within the sliding buckle slot 110 and securing it. Disassembly is similar; the external magnet drives the sliding buckle 108 to slide into the circular groove of the sliding buckle slot 110, allowing for disassembly.

[0045] It should be noted that whether connecting or disassembling, the metal panel 104 needs to be pressed tightly to reduce the gap between the metal panel 104 and the plastic substrate 102, thereby reducing the friction between the slider 108 and the slider slot 110.

[0046] Since the metal panel 104 is the outermost layer and most susceptible to damage, it is designed to be detachable, while the other three layers are designed to be fixedly connected. When the metal panel 104 is damaged, only the metal panel 104 can be replaced while retaining the other three layers, which not only reduces usage and maintenance costs but also simplifies replacement. In addition, the connector between the metal panel 104 and the plastic substrate 102 is located inside the metal panel 104, ensuring that the outer surface of the metal panel 104 is smooth and flat.

[0047] In summary, this utility model uses a composite panel composed of a honeycomb panel 101, a plastic substrate 102, a plastic elastic layer 103, and a metal panel 104 to manufacture the car decorative panel, resulting in superior performance. The honeycomb panel 101, as the main supporting material, is made of aluminum-manganese alloy and is designed in a honeycomb shape to achieve weight reduction as much as possible while meeting strength requirements. The plastic substrate 102, as the core connecting plate, connects the other three layers, ensuring the overall stability of the car decorative panel.

[0048] Since the metal panel 104 is the outermost layer and most susceptible to damage, it is designed as a detachable connection, while the other three layers are designed as fixed connections. When the metal panel 104 is damaged, only the metal panel 104 can be replaced, retaining the other three layers. This not only reduces maintenance costs but also simplifies replacement. Furthermore, the connector between the metal panel 104 and the plastic substrate 102 is located inside the metal panel 104, ensuring a smooth and flat outer surface. The honeycomb panel 101, designed in a honeycomb pattern, also absorbs noise. The addition of a plastic elastic layer 103 further enhances noise absorption. Moreover, the elastic plastic layer 103 is elastic and can fill the gaps between the metal panel 104 and the plastic substrate 102, ensuring overall sealing and stability.
