Description

Technical Field

[0001] This utility model relates to the field of interior technology, specifically to interior components and vehicles. Background Technology

[0002] Currently, heating in vehicles and other vehicles mainly relies on air conditioning systems. Gasoline vehicles utilize engine waste heat, while electric vehicles mostly use PTC electric heaters. However, both suffer from slow heating response. During cold starts, it takes a long time for the water or air temperature to rise, resulting in a poor heating experience.

[0003] To address the issue of slow heating response in air conditioning systems, some technologies have proposed integrating heating elements into interior trim components. However, these interior trim components generally suffer from drawbacks such as rapid surface temperature increases and a harsh feel, negatively impacting the driving and riding experience. Utility Model Content

[0004] In view of this, the present invention provides an interior trim component and a carrier to solve or improve the problems of sudden surface temperature rise and stiff touch that are common in interior trim components in related technologies.

[0005] In a first aspect, this utility model provides an interior trim component, comprising: Matrix; A heating layer is disposed on the surface of the substrate and can generate heat when energized; A buffer layer is disposed on the surface of the heating layer opposite to the substrate; A mesh covering layer is disposed on the surface of the buffer layer opposite to the heating layer; Epidermal layer, which is disposed on the surface of the mesh covering layer opposite to the buffer layer.

[0006] In one optional embodiment, the mesh covering layer is a three-dimensional mesh structure; And / or, the buffer layer is a sponge layer or a foam layer.

[0007] In one optional embodiment, the surface of the substrate is provided with a receiving groove, and the heating layer and the buffer layer are sequentially stacked in the receiving groove along the depth direction of the receiving groove, with at least a portion of the mesh covering layer located outside the receiving groove.

[0008] In one optional embodiment, the heating layer includes a first protective layer, a heating element, and a second protective layer stacked sequentially, wherein an electrode layer is provided on the surface of the heating element near the first protective layer.

[0009] In one alternative embodiment, both the first protective layer and the second protective layer extend beyond the outer peripheral edge of the heating element, and the portions of the first protective layer and the second protective layer that extend beyond the heating element are bonded to each other.

[0010] In one optional embodiment, both the first protective layer and the second protective layer are provided with clearance grooves extending beyond the heating element, and the clearance grooves are arranged opposite to each other, with the heating element provided on both sides of the clearance grooves.

[0011] In one optional embodiment, the number of heating elements is at least two, and the at least two heating elements are distributed at intervals along the extension direction of the first protective layer or the second protective layer, and the at least two heating elements are connected in series or in parallel.

[0012] In one alternative embodiment, the heating element includes a carbon nanotube network structure, wherein the carbon nanotube network structure is provided with graphene oxide; Alternatively, the heating element may comprise a graphene layer.

[0013] In one optional embodiment, the electrode layer has a silver paste layer on the surface opposite to the heating element; And / or, the first protective layer is bonded to both the electrode layer and the heating element; And / or, the second protective layer is bonded to the heating element.

[0016] In addition, the porous structure of the mesh covering helps to distribute heat over a larger contact area, which helps to distribute the heat transferred from the buffer layer more evenly to the surface layer, achieving heat uniformity and avoiding heat concentration at a certain point. This results in a gradual and uniform temperature rise in the surface layer, thereby improving the thermal comfort of the interior components.

[0017] In addition, the cushioning layer is elastic. When a user touches the surface layer and applies pressure, the cushioning layer undergoes elastic deformation, absorbing the impact and providing a soft, resilient support, thus solving the problem of the harsh feel of hard interior trim components. At the same time, the surface layer, which is in direct contact with the human body, is itself soft, further enhancing the soft tactile feel.

[0022] 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.

[0023] To address the issue of slow heating response in air conditioning systems, some technologies have proposed integrating heating elements into interior trim components. However, these interior trim components generally suffer from drawbacks such as rapid surface temperature increases and a harsh feel, negatively impacting the driving and riding experience.

[0024] In order to solve or improve the problems of sudden surface temperature rise and harsh touch of interior parts in related technologies, this utility model provides an interior part and a vehicle.

[0025] The following is combined Figures 1 to 4 This describes the interior trim provided in the embodiments of the present invention.

[0026] Specifically, the interior components include a base 1, a heating layer 2, a buffer layer 3, a mesh covering layer 4, and a skin layer 5.

[0027] Among them, the base 1 serves as the skeleton of the interior parts and can be injection molded.

[0028] The heating layer 2 is disposed on the surface of the substrate 1, and the heating layer 2 can generate heat when energized, that is, the heating layer 2 is used to convert electrical energy into heat energy.

[0029] The buffer layer 3 is disposed on the surface of the heating layer 2 away from the substrate 1. It can be understood that the buffer layer 3 is elastic, that is, the buffer layer 3 can undergo elastic deformation when compressed and recover its deformation after the pressure is removed.

[0030] A mesh covering layer 4 is disposed on the surface of the buffer layer 3 facing away from the heating layer 2. Optionally, the mesh covering layer 4 is made of a mesh or fabric material, such as synthetic fibers, natural fibers, or metal wires, with different pore structures and textures. For example, the mesh covering layer 4 is a mesh layer.

[0031] The outer skin layer 5 is disposed on the surface of the mesh covering layer 4 facing away from the buffer layer 3. Optionally, the outer skin layer 5 can be fabric, leather, or synthetic material. Optionally, the substrate 1, heating layer 2, buffer layer 3, mesh covering layer 4, and outer skin layer 5 are bonded together in sequence.

[0032] In this embodiment, the buffer layer 3 can form thermal resistance on the path of heat transfer from the heating layer 2 to the epidermal layer 5, slowing down the heat conduction speed and allowing heat to be released slowly to the epidermal layer 5, thereby avoiding a sudden temperature rise and achieving a gradual temperature increase.

[0033] In addition, the porous structure of the mesh covering layer 4 provides more heat conduction paths and a larger surface area, which helps to distribute heat to a larger contact area. This helps to distribute the heat transferred from the buffer layer 3 to the skin layer 5 more evenly, achieving heat uniformity and avoiding heat concentration at a certain point. This makes the temperature rise of the skin layer 5 gradual and uniform, thereby improving the thermal comfort of the interior parts.

[0034] Furthermore, the buffer layer 3 is elastic. When a user contacts the outer skin layer 5 and applies pressure, the buffer layer 3 undergoes elastic deformation, absorbing the impact and providing a soft, elastic support, thus solving the problem of the harsh feel of hard interior trim components. At the same time, the outer skin layer 5, which is in direct contact with the human body, is made of a soft material, which further enhances the soft tactile feel.

[0035] In some embodiments of this invention, the mesh covering layer 4 is a three-dimensional mesh structure, for example, a 3D mesh. Optionally, the three-dimensional mesh structure includes a surface layer and an intermediate layer, with two surface layers disposed on either side of the intermediate layer, or the intermediate layer sandwiched between the two surface layers. For example, the surface layer is a mesh fabric, and the intermediate layer is a fiber filling layer supported between the two surface layers.

[0036] In this embodiment, the three-dimensional mesh structure can also produce a large degree of elastic compression and rebound. Therefore, when a person presses it, the three-dimensional mesh structure can be compressed significantly, providing a soft touch.

[0037] In addition, the fibers of the three-dimensional mesh structure act like tiny springs, sandwiched between two surface layers. When the user presses the outer skin layer 5, the pressure is transmitted through the outer skin layer 5 to the three-dimensional mesh knot, compressing the middle fiber layer, and then acting on the buffer layer 3, thereby providing a progressively soft touch to enhance the tactile experience of the driver and passengers.

[0038] Furthermore, the three-dimensional pores and channels within the three-dimensional mesh structure can form air convection channels. For example, after heat is transferred from the buffer layer 3, it can flow and diffuse within the gaps of the three-dimensional mesh structure, and be more evenly transferred to the epidermal layer 5 through convection and radiation. This results in smaller temperature differences throughout the epidermal layer 5, a smoother and more linear heating process, and prevents sudden temperature spikes at any point or in any area of ​​the epidermal layer 5, thus avoiding the problem of rapid temperature increases and providing a comfortable feeling of warmth.

[0039] In some embodiments provided by this utility model, the buffer layer 3 is a sponge layer. For example, the material of the sponge layer may be, but is not limited to, polyurethane sponge or slow rebound memory foam.

[0040] In this embodiment, the sponge is filled with a large number of tiny air bubbles, which causes the pore walls to bend and the air inside the pores to be expelled when pressure is applied, thereby producing significant and controllable deformation and giving the interior trim a clear and linear pressing feedback.

[0041] In addition, the porous structure of the sponge can significantly slow down the rate at which the heat generated by the heating layer 2 is transferred to the epidermal layer 5, preventing the temperature of the epidermal layer 5 from rising suddenly, and achieving a heating effect with a gradual temperature rise and a gentle feeling.

[0042] In addition, the sponge can be easily and precisely processed into any shape and thickness as required through die-cutting or molding processes, thereby improving the fit between the buffer layer 3 and components such as the base 1, heating layer 2 and mesh covering layer 4, and thus ensuring the smoothness of the interior parts surface.

[0043] Of course, the buffer layer 3 is not limited to being a sponge layer. For example, in other embodiments provided by this utility model, the buffer layer 3 can also be a foam layer.

[0044] In this embodiment, by adjusting process parameters such as foaming ratio and pore size, the softness, elasticity, and thermal conductivity can be flexibly customized to suit the tactile and functional requirements of different parts of the interior. Simultaneously, the porous elastic structure of the foam layer provides a soft, cushioning effect under pressure, improving the problem of a harsh tactile feel. Furthermore, the large amount of air inside the foam layer insulates against heat and slows heat transfer, preventing a sudden temperature rise in the surface layer 5 and achieving stable heating.

[0045] refer to Figure 1 As shown, in some embodiments provided by this utility model, the surface of the substrate 1 is provided with a receiving groove 101. Along the depth direction of the receiving groove 101, the heating layer 2 and the buffer layer 3 are sequentially stacked in the receiving groove 101.

[0046] Furthermore, at least a portion of the mesh covering layer 4 is located outside the receiving groove 101. For example, a portion of the mesh covering layer 4 is disposed inside the receiving groove 101 and connected to the buffer layer 3, while another portion is disposed outside the receiving groove 101. Alternatively, the buffer layer 3 may be flush with the opening of the receiving groove 101, and the entire mesh covering layer 4 may be located outside the receiving groove 101.

[0047] In this embodiment, the receiving groove 101 provides a precise mounting position for the heating layer 2 and the buffer layer 3. For example, during the assembly process, there is no need to repeatedly calibrate the positions of the heating layer 2, the buffer layer 3, and the substrate 1. Precise positioning can be achieved by directly embedding them into the receiving groove 101, thereby reducing assembly difficulty and avoiding problems such as uneven product thickness, uneven edges, or offset heating areas caused by interlayer misalignment. This ensures the consistency and stability of product quality, making it particularly suitable for mass production scenarios.

[0048] In addition, the receiving groove 101 provides physical limiting space for the heating layer 2 and the buffer layer 3, preventing them from shifting due to vibration or pressing, and ensuring that the layers are always tightly attached. This ensures both uniform heat transfer and prevents tactile discontinuity caused by delamination.

[0049] Optionally, the depth of the receiving groove 101 is 2.5mm-3.5mm, for example, the depth of the receiving groove 101 is 2.5mm, 3mm, or 3.5mm.

[0050] Optionally, the thickness of the heating layer 2 is 0.5mm-0.7mm, for example, the thickness of the heating layer 2 is 0.5mm, 0.6mm or 0.7mm.

[0051] Optionally, the thickness of the buffer layer 3 is 1mm-2mm, for example, the thickness of the buffer layer 3 is 1mm, 1.5mm or 2mm.

[0052] Optionally, the thickness of the mesh cover layer 4 is 2mm-3mm, for example, the thickness of the mesh cover layer 4 is 2mm, 2.5mm or 3mm.

[0053] refer to Figure 3 and Figure 4 As shown, in some embodiments provided by this utility model, the heating layer 2 includes a first protective layer 201, a heating element 202, and a second protective layer 203 stacked sequentially.

[0054] The heating element 202 has an electrode layer 204 on its surface near the first protective layer 201. It is understood that the electrode layer 204 includes positive and negative electrodes arranged at intervals. The positive and negative electrodes are used to connect to the positive and negative terminals of a power source, respectively. When current flows through the heating element 202, the heating element 202 generates heat.

[0055] In this embodiment, the first protective layer 201 and the second protective layer 203 enclose the heating element 202, which can isolate the heating element 202 from direct contact with the external buffer layer 3 and the substrate 1, avoid the risk of leakage, and at the same time block external moisture and dust from entering, thereby preventing the heating element 202 from getting damp or oxidized, and eliminating the risk of short circuit.

[0056] In some embodiments provided by this utility model, the first protective layer 201 and the second protective layer 203 both extend beyond the outer peripheral edge of the heating body 202, and the portions of the first protective layer 201 and the second protective layer 203 that extend beyond the heating body 202 are bonded to each other.

[0057] In this embodiment, after the extended portions of the first protective layer 201 and the second protective layer 203 are bonded together, a sealed frame can be formed around the heating element 202 to prevent external moisture and dust from entering the heating element 202 and the electrode layer 204, thereby avoiding the risk of short circuit or leakage, and preventing the heating element 202 material from aging due to contact with moisture.

[0058] Meanwhile, edge bonding can firmly clamp the heating element 202 between the two protective layers, preventing the heating element 202 from shifting, wrinkling or partially detaching during long-term vibration and pressing, ensuring stable contact between the electrode layer 204 and the heating element 202, and guaranteeing uniform heating and service life.

[0059] refer to Figure 4 As shown, in some embodiments provided by this utility model, the portions of the first protective layer 201 and the second protective layer 203 that extend beyond the heating body 202 are both provided with relief grooves 205, and the relief grooves 205 of the first protective layer 201 and the second protective layer 203 are arranged opposite to each other.

[0060] Heating elements 202 are provided on both opposite sides of the clearance groove 205. Specifically, the clearance groove 205 is opposite to the opening on the substrate 1, and correspondingly, the buffer layer 3, the mesh covering layer 4, and the skin layer 5 are all provided with corresponding clearance grooves at positions opposite to the openings. For example, the opening on the substrate 1 can be used to arrange air outlets, operating buttons, handles, speakers, or ambient lights.

[0061] In this embodiment, the protective layer, buffer layer 3, mesh covering layer 4 and skin layer 5 are provided with clearance grooves 205 at the positions corresponding to the openings of the substrate 1. This can accurately avoid functional components such as air outlets, buttons, speakers or ambient lights, without affecting the normal installation and use of these components, and can extend the heating function to the periphery of the functional components, realizing the coexistence of the heating area and the functional area, and avoiding the lack of heating coverage due to the presence of functional components.

[0062] Optionally, the interior trim is an armrest on the inner side of the door panel. Correspondingly, the base 1 is configured as an armrest frame, which has a side surface and a support surface. The support surface is located on the top surface of the armrest frame, allowing the driver and passengers to lean against it. The side surface intersects with the support surface. The side surface of the armrest frame has an opening, and a clearance groove 205 is disposed opposite to the opening. A heating element on one side of the clearance groove 205 is disposed on the side surface, and at least a portion of the heating element on the other side of the clearance groove 205 is disposed on the support surface.

[0063] In this embodiment, the support surface of the armrest frame is the main area for the driver's arm to lean on, and the side is the auxiliary contact area. The two core contact surfaces are covered with heating elements, which can better cover the actual contact area of ​​the driver's arm, providing a surrounding warm experience, quickly providing full-area warmth to the arm, and avoiding a break in the sensation.

[0064] In addition, by arranging heating elements on both sides of the opening, the opening structure can be bypassed, and the heating elements on the support surface can supplement the heat around the opening, avoiding the formation of a low-temperature zone in the opening area without heating elements, ensuring uniform heating of the entire handrail, and improving the user experience in winter.

[0065] refer to Figure 4 As shown, in some embodiments provided by this utility model, the number of heating elements 202 is at least two, and the at least two heating elements 202 are distributed at intervals along the extension direction of the first protective layer 201 or the second protective layer 203, and the at least two heating elements 202 are connected in series or in parallel.

[0066] In this embodiment, multiple heating elements 202 are distributed to cover a wider area, avoiding temperature attenuation at the edges of a single large-area heating element 202 and achieving uniform temperature rise over a large area. Furthermore, for irregularly shaped areas such as handrails with openings, multiple heating elements 202 can be arranged in sections on both sides of the opening or on different curved surfaces, avoiding functional components while achieving full coverage and solving the problem that a single heating element 202 is difficult to adapt to complex shapes.

[0067] refer to Figure 4 As shown, optionally, at least two heating elements are arranged on both sides of the clearance groove 205, and the heating elements on the same side of the clearance groove 205 are arranged in series.

[0068] In some embodiments provided by this utility model, the heating element 202 includes a carbon nanotube network structure, and the carbon nanotube network structure is provided with graphene oxide. For example, the carbon nanotube network structure can be prepared by vapor deposition, and graphene oxide is doped into the carbon nanotube network structure.

[0069] In this embodiment, the carbon nanotube network structure is a continuous, mesh-like conductive pathway formed by countless interconnected nanoscale tubular fibers. The addition of graphene oxide can fill the gaps in the network, further enhancing the continuity and density of the pathway. The nanotube network itself has excellent electrical and thermal conductivity, and combined with the high carrier mobility of graphene oxide, it can achieve efficient conversion of electrical energy into thermal energy and rapid heating.

[0070] In addition, the three-dimensional network structure can make the current distribution uniform, that is, the current can flow evenly throughout the entire network, thereby eliminating local hot spots and achieving uniform surface heating, which in turn makes the temperature consistency of the epidermis layer 5 higher.

[0071] In addition, the carbon nanotube network structure has good flexibility and bendability, which can closely fit irregular curved surfaces such as armrests, and can better adapt to the complex three-dimensional structure of interior parts.

[0072] Of course, the heating element 202 is not limited to the above-mentioned carbon nanotube network structure. For example, in other embodiments provided by this utility model, the heating element 202 includes a graphene layer.

[0073] In this embodiment, graphene has good thermal conductivity and electrothermal conversion efficiency. After being energized, it can heat up quickly and the heat can be diffused evenly, thereby shortening the heating response time and reducing local overheating, thus improving the immediacy and comfort of heating in winter.

[0074] In addition, the graphene layer has excellent flexibility, can be bent and fit the curved surface of the interior parts, and has outstanding bending resistance, so it is not easy to break or degrade in performance after long-term use.

[0075] In some embodiments of this invention, a silver paste layer 206 is provided on the surface of the electrode layer 204 facing away from the heating element 202. Optionally, the electrode layer 204 is a copper foil.

[0076] In this embodiment, the silver paste, with its high conductivity, serves as an excellent contact layer when applied to the surface of the electrode layer 204. This reduces the contact resistance at the connection point between the wire and the electrode layer 204, ensuring less current loss from the wire to the electrode layer 204, thereby reducing unnecessary heat generation and improving system efficiency. Simultaneously, the low resistivity of the silver paste helps the current flow more evenly to all parts of the electrode layer 204, contributing to balanced electrode current density, preventing localized overcurrent heating, and improving heating uniformity.

[0077] In addition, the silver paste layer 206 can serve as a protective coating to prevent the electrode layer 204 from oxidizing or corroding, and can extend the service life of the heating layer 2, especially in humid and hot environments.

[0078] In some embodiments provided by this utility model, the first protective layer 201 is bonded to both the electrode layer 204 and the heating element 202. Specifically, the area of ​​the heating element 202 is larger than that of the electrode layer 204, so the electrode layer 204 only covers a small portion of the heating element 202. Therefore, the first protective layer 201 can be bonded to both the electrode layer 204 and the heating element 202.

[0079] In this embodiment, the first protective layer 201 adheres to both the electrode layer 204 and the non-electrode-covered area of ​​the heating element 202, forming a full-area bond. This significantly improves the overall anti-peeling ability of the heating layer 2 and prevents interlayer separation caused by long-term vibration and pressure. Furthermore, the electrode layer 204 is firmly bonded to the edges by the protective layer, preventing electrode misalignment, warping, or poor contact due to thermal expansion and contraction or external forces, thus ensuring the electrical reliability of the heating layer 2.

[0080] Optionally, the first protective layer 201 is made of non-woven fabric. For example, the first protective layer 201 can be bonded to the electrode layer 204 and the heating element 202 with PET adhesive. It is understood that the main component of PET adhesive is polyethylene terephthalate.

[0081] In this embodiment, the nonwoven fabric itself is an insulator and is very soft, which can well adapt to the surface contours of the heating element 202 and the electrode layer 204 without increasing the overall rigidity. At the same time, the porous structure of the nonwoven fabric allows adhesive to penetrate in, forming a strong mechanical interlock and improving the bonding strength of the first protective layer 201.

[0082] In addition, PET adhesive has good adhesion to various surfaces such as non-woven fabric, electrode layer 204 and heating element 202, and can withstand the normal operating temperature of heating element 202 without softening, melting or failing, ensuring long-term reliability.

[0083] In some embodiments provided by this utility model, the second protective layer 203 is bonded to the heating element 202.

[0084] In this embodiment, the direct bonding between the second protective layer 203 and the heating element 202 can completely clamp the heating element 202 between the two protective layers, forming a fixed structure that fits together. This not only prevents the heating element 202 from shifting or wrinkling between the layers, but also reduces the deformation of the heating element 202 caused by temperature changes or external pressure through the synergistic constraint of the two protective layers, thus ensuring uniform heating.

[0085] Optionally, the second protective layer 203 is made of non-woven fabric. For example, the second protective layer 203 can be bonded to the heating element 202 with PET adhesive.

[0086] In this embodiment, the nonwoven fabric itself is an insulator and is very soft, which can adapt well to the surface contour of the heating element 202 without increasing the overall rigidity. At the same time, the porous structure of the nonwoven fabric allows adhesive to penetrate in, forming a strong mechanical interlock and improving the bonding strength of the first protective layer 201.

[0087] In addition, PET adhesive has good adhesion to various surfaces such as non-woven fabric heating element 202, and can withstand the normal operating temperature of heating element 202 without softening, melting or failing, ensuring long-term reliability.

[0088] It is understood that the technical features in the above embodiments can be combined with each other.

[0089] The base 1 serves as the framework for the interior trim and can be injection molded. A receiving groove 101 is provided on the surface of the base 1. A heating layer 2 and a buffer layer 3 are sequentially stacked within the receiving groove 101 along its depth direction. At least a portion of the mesh covering layer 4 is located outside the receiving groove 101. The base 1 is configured as an armrest framework, which has sides and a support surface. The support surface is located on the top surface of the armrest framework for passengers to lean against. The sides intersect with the support surface, and the sides of the armrest framework have openings.

[0090] The heating layer 2 includes a first protective layer 201, a heating element 202, and a second protective layer 203 stacked sequentially. An electrode layer 204 is provided on the surface of the heating element 202 near the first protective layer 201.

[0091] Both the first protective layer 201 and the second protective layer 203 have clearance grooves 205 extending beyond the heating element 202. The clearance grooves 205 of the first protective layer 201 and the second protective layer 203 are arranged opposite to each other, and heating elements 202 are provided on both opposite sides of the clearance grooves 205. The clearance grooves 205 are arranged opposite to the opening. The heating element on one side of the clearance groove 205 is located on the side surface, and at least a portion of the heating element on the other side of the clearance groove 205 is located on the support surface.

[0092] The heating element 202 includes a carbon nanotube network structure, which is provided with graphene oxide. The electrode layer 204 has a silver paste layer 206 on its surface facing away from the heating element 202.

[0093] The first protective layer 201 is made of non-woven fabric. For example, the first protective layer 201 can be bonded to the electrode layer 204 and the heating element 202 with PET adhesive. The second protective layer 203 is made of non-woven fabric. For example, the second protective layer 203 can be bonded to the heating element 202 with PET adhesive.

[0094] The mesh covering layer 4 has a three-dimensional mesh structure. The skin layer 5 is disposed on the surface of the mesh covering layer 4 facing away from the buffer layer 3. Optionally, the skin layer 5 can be fabric, leather, or synthetic material.
