Detailed Implementation

[0036] The perforated cladding panels in the related technologies use an open-hole light-transmitting structure, which has problems such as significant changes in brightness with the viewing angle, easy accumulation of dust due to exposed holes, limited light-emitting area, narrow viewing angle, and small visible range.

[0037] To address the aforementioned issues, this utility model provides a translucent outer skin and a vehicle trim piece. By filling the translucent holes with a decorative layer, the translucent outer skin effectively improves brightness consistency, expands the viewing angle, and enhances dustproof performance and ease of cleaning, thereby significantly optimizing the overall lighting effect and appearance quality.

[0038] 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, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0042] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0043] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0044] The following detailed description of the overall structure, working principle, and technical effects of the translucent skin and vehicle trim provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0045] Please see Figures 1 to 6 This utility model provides a light-transmitting skin 10, which is applied to the vehicle trim 1. It can effectively improve the brightness consistency and expand the viewing angle by filling the light-transmitting hole 11 with a decorative layer 500, while also improving dustproof performance and cleaning convenience.

[0046] Specifically, the translucent outer skin 10 includes a base fabric layer 200, a perforated layer 400, and a finishing layer 500. The perforated layer 400 is disposed on the base fabric layer 200, and both the perforated layer 400 and the base fabric layer 200 have at least one light-transmitting hole 11, which continuously penetrates both the perforated layer 400 and the base fabric layer 200. Based on the above, the finishing layer 500 is disposed on the side of the perforated layer 400 away from the base fabric layer 200 and fills the light-transmitting hole 11. It should be noted that the finishing layer 500 is made of a translucent material and is used to provide color, pattern, texture, non-sticky feel, and / or improve light transmission.

[0047] Because the decorative layer 500 fills the light-transmitting hole 11, the light-transmitting hole 11 can maintain a stable light output under different viewing angles, avoiding brightness reduction or light obscuration caused by changes in viewing angle, and further improving brightness consistency. Furthermore, since the decorative layer 500 also covers the surface of the perforated layer 400, it can form a closed protective structure, effectively preventing dust from entering the interior of the light-transmitting hole 11, thereby ensuring the overall cleanliness and ease of cleaning of the light-transmitting skin 10.

[0048] During operation, light passes sequentially from below through the base fabric layer 200 and the perforated layer 400, and exits through the light-transmitting hole 11 filled with the decorative layer 500. Because the decorative layer 500 itself participates in light guiding, the visible light passing through the light-transmitting hole 11 is diffused and diffused by the decorative layer 500, thereby improving the uniformity of illumination, enhancing visual comfort, and expanding the viewing angle of a single light-transmitting hole 11. The aforementioned viewing angle can be... Figure 1 and Figure 2 The α angle shown is intuitively represented.

[0049] In the embodiments provided in this application, the perforated layer 400 includes at least one of a silicone layer, a polyvinyl chloride layer, a thermoplastic elastomer layer, and a polyurethane layer. It should be noted that all of the above-mentioned material layers have good processability and mechanical properties, meeting the process requirements of punching, and also have good adhesion and material compatibility with adjacent layers, which is beneficial to improving the stability and reliability of the overall structure.

[0050] Specifically, polyurethane (PU) is a polymer formed by the chemical reaction of organic polyisocyanates and hydroxyl-terminated compounds, containing repeating urethane segments in its structure. Polyurethane possesses high tensile strength, tear strength, and good impact resistance. It exhibits excellent resistance to many chemicals, remaining stable in harsh environments such as acids, alkalis, and solvents. It also demonstrates good oil resistance and biocompatibility. Furthermore, it can be processed through various techniques such as injection molding, extrusion, and calendering, easily molded into products of various complex shapes to meet diverse industrial needs.

[0051] Polyvinyl chloride (PVC) is a polymer formed by the polymerization of vinyl chloride monomers under the action of initiators such as peroxides and azo compounds or under the action of light and heat according to the free radical polymerization mechanism. It has good physical and chemical properties, such as strong resistance to acids and alkalis, good chemical stability and good electrical insulation.

[0052] Thermoplastic polyolefin elastomer (TPO) is a polymer material composed of two components: rubber and polyolefin. It combines the high elasticity of rubber with the processing characteristics of plastic. It exhibits high elasticity at room temperature and can be plasticized and molded at high temperature.

[0053] like Figure 1 As shown, the surface of the perforated layer 400 away from the base fabric layer 200 is the light-emitting surface. In addition, the translucent skin 10 also includes a light-shielding layer 300 disposed between the perforated layer 400 and the base fabric layer 200. This light-shielding layer 300 prevents light from escaping from the back of the light-emitting surface, thereby avoiding light leakage in unintended areas and improving illumination efficiency and visual clarity. Typically, the light-shielding layer 300 is dark, such as black, to effectively absorb or block light, ensuring that the light source 31 only emits light through the designated light-transmitting holes 11, thus creating a clear, bright, and high-contrast lighting effect.

[0054] Optionally, the light-shielding layer 300 is made of a light-shielding silicone material, which not only has good flexibility and weather resistance, but is also easy to process into devices, and is suitable for composite integration with the perforated layer 400 and the base fabric layer 200.

[0055] In this embodiment, the light-transmitting hole 11 sequentially penetrates the perforated layer 400, the light-shielding layer 300, and the base fabric layer 200, thereby effectively limiting and guiding the direction of light propagation. Furthermore, in some embodiments where the perforated layer 400 itself is not translucent, such as... Figure 2 As shown, no additional light-blocking layer 300 is required. This design also ensures that light only shines out from the light-transmitting holes 11, ensuring that light does not cross between the individual light-transmitting holes 11, thereby maintaining clear and uniform lighting effects.

[0056] It is understood that, based on the selective setting of the light-shielding layer 300, the perforated layer 400 can be set to any color, and this utility model does not impose any limitations. Also based on the above, regardless of whether the light-shielding layer 300 is set, the preset patterned lighting effect can be achieved by adjusting the shape, size, or arrangement of the light-transmitting holes 11.

[0057] Specifically, the shape of the light-transmitting aperture 11 can be designed as a circle, square, polygon, or other complex geometric shape to meet different visual needs. Variations in size can control the amount of light transmitted, thereby adjusting the intensity and uniformity of illumination. Furthermore, the arrangement of the light-transmitting apertures 11 can create unique light and shadow effects through orderly arrangement or random distribution, such as forming specific text, graphics, or textures.

[0058] like Figure 1 and Figure 2 As shown, there are multiple light-transmitting holes 11, each with a different aperture, which gradually increases or decreases along the arrangement direction, resulting in a gradient difference in the corresponding light transmission brightness. This creates a visual effect of gradual brightness variation on the light-transmitting surface 10. Based on this design, not only is the sense of layering and artistry of the lighting performance enhanced, but the overall visual appeal is also strengthened. This allows the product to present a more distinctive and sophisticated light and shadow effect when the light source 31 is turned on, making it suitable for application scenarios with high requirements for both decorative and lighting quality.

[0059] For example, such as Figure 5 Show, Figure 5 This embodiment provides a schematic diagram of the arrangement of light-transmitting holes 11 with different aperture sizes. Along the arrangement direction (from top to bottom), the aperture size of the light-transmitting holes 11 can be set to gradually decrease from 3mm to 1.5mm, and then further to 0.6mm, thereby forming a gradually changing size gradient. It can be understood that as the aperture size continuously decreases, the amount of light passing through each light-transmitting hole 11 also gradually decreases, thus presenting a gradient light and shadow effect from bright to dark on the surface of the light-transmitting skin 10, effectively enhancing the visual sense of layering and artistic expression.

[0060] To ensure that the translucent outer skin 10 also provides a soft feel, the translucent outer skin 10 also includes a soft touch layer 100, which is located on the side of the base fabric layer 200 away from the perforated layer 400. Furthermore, while improving the tactile quality, to ensure that the light source 31 can be smoothly transmitted to the light-transmitting hole 11 and achieve good optical performance and visual effects, the soft touch layer 100 is made of a semi-translucent material or has a semi-translucent structure, so that visible light can pass through the soft touch layer 100 and enter the light-transmitting hole 11.

[0061] In an optional embodiment, the soft touch layer 100 is specifically a 3D mesh fabric made of fibers. It should be noted that 3D mesh fabric is a pure woven material with excellent elasticity and support, possessing good resilience, moisture permeability, mechanical strength, and chemical stability. This material provides cushioning protection and a comfortable tactile experience for the product. Based on the aforementioned material, when light shines through the soft touch layer 100 onto the light-transmitting hole 11, the clarity of the pattern caused by refraction or scattering from the surface decorative layer can be reduced.

[0062] Furthermore, it should be noted that in one embodiment of this utility model, the base fabric layer 200 is also made of fiber, and the soft contact layer 100 is bonded to the base fabric layer 200 with adhesive. The adhesive used can be one of polyurethane organic solvent, neoprene rubber organic solvent, styrene organic solvent, or polyurethane water solvent. This choice of adhesive effectively solves the problems of bulging, loosening, and wrinkling that easily occur with existing translucent skin 10 on concave surfaces or large-area samples.

[0063] Please refer to it again. Figure 1 , Figure 2 as well as Figure 4 The decorative layer 500 includes a filling portion 510, which is located on the side of the perforated layer 400 away from the base fabric layer 200 and fills the light-transmitting holes 11 to provide color, pattern, texture and / or improve light transmission.

[0064] Corresponding to the above, the filling portion 510, which fills the light-transmitting hole 11 or covers the perforated layer 400, diffuses and reflects the light passing through, thereby improving the uniformity of illumination, visual comfort, and viewing angle. Based on this filling arrangement, the light-transmitting hole 11 can maintain a stable light output at different viewing angles, avoiding problems such as decreased brightness or loss of light visibility due to changes in viewing angle.

[0065] Furthermore, in practical scenarios, when the light source 31 is turned on, the filling portion 510 has a color compensation function, which can adjust the color performance of the light to make the final color more saturated and uniform. At the same time, the pattern in the non-transparent area of ​​the filling portion 510 can absorb or scatter excess light, effectively preventing the edges of the pattern in the light-transmitting hole 11 from becoming blurry, and improving the clarity and visual recognition of the pattern. When the light source 31 is turned off, the pattern in the light-transmitting hole 11 is not visible, and the translucent surface 10 only shows the color, pattern and / or texture of the filling portion 510, which blends harmoniously with the surrounding environment. At this time, the translucent surface 10 maintains the visual richness and decorative beauty of the overall surface through the design of patterns, wood grain, brushed textures, star dots, geometric textures, etc. on the filling portion 510.

[0066] Furthermore, the finishing layer 500 also includes a tactile portion 530, which is located on the side of the filling portion 510 away from the perforated layer 400, and is used to provide a non-sticky feel. That is to say, the tactile portion 530 enables the translucent skin 10 to have a cool, dry touch experience. Moreover, the tactile portion 530 also exhibits good dirt resistance, meeting the experimental requirements for the ease of cleaning and maintenance of the translucent skin 10 in an automotive environment.

[0067] Optionally, the filling portion 510 includes a transparent silicone material layer 511 and a transparent silicone filler 513. The transparent silicone filler 513 fills the light-transmitting hole 11, and the transparent silicone material layer 511 covers the upper surface of the perforated layer 400. In other words, the filling portion 510 is made of transparent silicone, possessing excellent light transmittance and light-guiding properties. It not only maintains the stability of light output from the light-transmitting hole 11 under different viewing angles but also effectively diffuses and diffuses light, thereby improving illumination uniformity and visual comfort.

[0068] Furthermore, transparent silicone materials possess excellent weather resistance, chemical stability, and flexibility, making them suitable for various processing techniques and facilitating a strong bond and structural stability between the filler layer 510 and the perforated layer 400. Alternatively, other transparent soft materials may be used in other embodiments.

[0069] Furthermore, the upper surface of the filling portion 510 is provided with a concave-convex structure, and the lower surface of the tactile portion 530 is provided with a mating structure that matches the concave-convex structure. Based on the above configuration, on the one hand, the concave-convex structure and the mating structure can present a three-dimensional pattern, texture, or embossed effect as a whole; on the other hand, the tight fit between the concave-convex structure and the mating structure also helps to enhance the connection stability between the tactile portion 530 and the filling portion 510, preventing misalignment or detachment during use. In other words, the above design improves both the functionality and aesthetics of the product.

[0070] Similarly, an uneven structure can be provided on the upper surface of the perforated layer 400, and a matching mating structure can be provided on the lower surface of the filling portion 510. These two structural designs do not conflict with each other; either one can be chosen, or both can be used simultaneously to further enhance the overall structural stability and visual appeal. Because the filling portion 510 has a certain degree of transparency, the uneven structures provided on the perforated layer 400 and / or the filling portion 510 can be observed with the naked eye.

[0071] Specifically, the raised and recessed structures take various forms, including tiny, repetitive textures such as stripes, wavy lines, and dot matrix. On the one hand, when the light source 31 is turned on, these textures guide the light to create a soft visual transition; on the other hand, when the light source 31 is turned off, they maintain the visual richness and decorative aesthetics of the overall surface. Furthermore, to suit applications with high aesthetic requirements, the raised and recessed structures can also be designed with specific patterns such as plant motifs, geometric shapes, or abstract graphics. To further enhance the product's identification function and personalized expression, the raised and recessed structures can also use customized patterns, such as brand logos, characters, or totems.

[0072] Additionally, the tactile part 530 includes a transparent silicone resin layer and / or a polyurethane material layer. It should be noted that the polyurethane material layer has already been explained above and will not be repeated here. The transparent silicone resin possesses excellent optical transparency and uniform light transmission properties, enabling the color, pattern, and / or texture of the filling part 510 or the perforated layer 400 surface to be clearly displayed when the light source 31 is turned off, thus enhancing the overall visual appeal. Simultaneously, when the light source 31 is turned on, similar to the transparent silicone material, the transparent silicone resin itself also possesses light-guiding properties. Visible light passing through the filling part 510 is further diffused and diffused through the tactile part 530, thereby further expanding the viewing angle of the individual light-transmitting hole 11.

[0073] It should also be noted that the transparent silicone resin surface has extremely low surface energy, exhibiting excellent anti-stick properties and not easily attracting dust and grease. This not only improves the dryness of the touch but also enhances the product's resistance to dirt and ease of cleaning.

[0074] In an optional embodiment, the decorative layer 500 is formed on the perforated layer 400 by a calendering process and fills the light-transmitting holes 11. It should be noted that the calendering process has advantages such as uniform material distribution and high production efficiency, and can form a structure with uniform thickness and smooth surface of the decorative layer 500 during processing, thereby improving the appearance quality and optical performance of the product.

[0075] Furthermore, this process is applicable to various flexible or semi-fluid dynamic materials such as silicone and polyurethane, and can adhere well to the surface of the perforated layer 400 and effectively fill complex structures. At the same time, by adjusting the temperature and pressure during calendering, the physical interlocking and interface bonding between the filling part 510 and the perforated layer 400 can be enhanced, further improving the reliability of the overall structure.

[0076] Please see Figure 6 The manufacturing process and technology of the translucent skin 10 provided in this embodiment of the present invention are as follows:

[0077] First, a light-shielding layer 300 is laminated onto the upper surface of the base fabric layer 200, and then a perforated layer 400 is laminated onto the upper surface of the light-shielding layer 300. At this time, the upper surface of the perforated layer 400 can have a preset texture or pattern. Subsequently, a punching process is performed to form light-transmitting holes 11 with various patterns. Next, a filling portion 510 is formed on the surface of the perforated layer 400 through a calendering process, simultaneously filling the light-transmitting holes 11. Similar to the perforated layer 400, the upper surface of the filling portion 510 can also be provided with a texture or pattern. Likewise, a tactile portion 530 is also formed on the filling portion 510 through a calendering process, thereby achieving continuity and stability of the overall structure.

[0078] Furthermore, the working principle and process of the translucent epidermis 10 provided in this embodiment of the present invention are as follows:

[0079] With the light source 31 on, light passes sequentially from bottom to top through the soft-touch layer 100 (if configured), the base fabric layer 200, the light-shielding layer 300 (if configured), and the perforated layer 400, and finally exits through the decorative layer 500 filling the light-transmitting hole 11. Because the decorative layer 500 has good light transmission properties, the light-transmitting hole 11 maintains a stable light output at different viewing angles, avoiding brightness reduction or light obscuration due to changes in viewing angle. Furthermore, because the decorative layer 500 has a certain light-guiding mechanism, it can diffuse and reflect light, expanding the viewing angle.

[0080] Specifically, the decorative layer 500 includes a filling portion 510 and a tactile portion 530. The filling portion 510 is disposed on the perforated layer 400 and fills the light-transmitting holes 11, and includes a transparent silicone material layer 511 and a transparent silicone filler 513. When the light source 31 is turned on, the filling portion 510 can enhance the clarity and color saturation of the light and shadow effect; while when the light source 31 is turned off, the texture or pattern on its own surface or the surface of the perforated layer 400 can maintain the overall aesthetic appearance of the surface, thereby achieving a unity of decoration and function.

[0081] The tactile part 530 is located on the side of the filling part 510 away from the perforated layer 400, and includes a transparent silicone resin layer and / or a polyurethane material layer. It has properties such as non-stickiness, dirt resistance, and easy cleaning, providing users with a dry and comfortable tactile experience and improving the product's usability and ease of maintenance. Furthermore, when the light source 31 is turned off, the transparent silicone resin can clearly display the color, pattern, and texture of the surface of the filling part 510 or the perforated layer 400, enhancing the overall visual appeal. When the light source 31 is turned on, its light-guiding properties further diffuse and reflect light, expanding the viewing angle of a single light-transmitting hole 11.

[0082] In summary, this utility model provides a translucent skin 10, comprising a base fabric layer 200, a perforated layer 400, and a decorative layer 500. The translucent holes 11 continuously penetrate the perforated layer 400 and the base fabric layer 200. The decorative layer 500 is located on the side of the perforated layer 400 away from the base fabric layer 200 and fills the translucent holes 11. It is made of a translucent material and provides color, pattern, texture, non-sticky feel, and / or improves light transmission. During operation, light passes sequentially from below through the base fabric layer 200 and the perforated layer 400, and exits through the translucent holes 11 filled with the decorative layer 500. Because the decorative layer 500 has translucency and a certain light-guiding ability, it diffuses and diffuses the light passing through the translucent holes 11, improving illumination uniformity, visual comfort, and viewing angle. Based on the above filling settings, the light-transmitting hole 11 can maintain a stable light output under different viewing angles, avoiding the problem of decreased brightness or invisible light due to changes in viewing angle. At the same time, it effectively prevents dust from entering the interior of the light-transmitting hole 11, improving the cleanliness and maintenance convenience of the overall structure.

[0083] Additionally, please see Figures 7 to 9 This utility model also provides a vehicle trim piece 1, which is applied to interior dashboards, door panels, center consoles, pillar pedals, and / or headliners. The vehicle trim piece 1 includes a light source assembly 30, a covering frame 50, and a light-transmitting skin 10 as described in any of the preceding embodiments. The covering frame 50 is made of a transparent or semi-transparent material. The light-transmitting skin 10, the covering frame 50, and the light source assembly 30 are arranged sequentially from top to bottom, so that visible light emitted from the light source assembly 30 can pass through the covering frame 50 to the light-transmitting skin 10.

[0084] It should be noted that, as shown above, since the vehicle trim 1 includes the light-transmitting skin 10 of the aforementioned embodiment, it also possesses the various technical effects brought about by the light-transmitting skin 10. Specifically, the vehicle trim 1 not only effectively improves the brightness consistency of light under different viewing angles and expands the viewing angle, but also enhances dustproof performance and ease of cleaning, thereby significantly optimizing the overall lighting effect and appearance quality.

[0085] In addition, it should be noted that the thickness of the tactile part 530, the thickness of the filling part 510, the thickness of the perforated layer 400, the thickness of the base fabric layer 200, the thickness of the soft touch layer 100, the thickness of the covering skeleton 50, as well as the transmittance, the distance between the centers of two adjacent light-transmitting holes 11, and the aperture size of the light-transmitting hole 11 (generally ≥0.2 mm) are all factors affecting the viewing angle α. In this embodiment, the viewing angle α is expanded by the diffuse reflection of the modification layer 500, so the specific details of these parameters will not be elaborated further.

[0086] like Figure 10 The covering skeleton 50 shown provides a stable support base for the light-transmitting skin 10, while also facilitating the guidance and uniform distribution of light. On this basis, the light-transmitting skin 10 (specifically, the soft contact layer 100 therein) is adhered to the outer surface of the covering skeleton 50 with adhesive, ensuring good adhesion and sealing between the two, thereby improving the stability of the overall structure and the uniformity of light illumination.

[0087] Furthermore, such as Figure 8 , Figure 9 as well as Figure 11 As shown, the vehicle trim 1 also includes a dome-shaped mounting bracket 70, which is fixedly connected to the covering frame 50 and together with the covering frame 50 defines an accommodating cavity for accommodating the light source assembly 30. Through the above structural design, the dome-shaped covering frame 50 and the mounting bracket 70 cooperate to form a closed or semi-closed accommodating space, providing a good installation positioning and protective environment for the light source assembly 30, while facilitating later maintenance and replacement.

[0088] It should be noted that the light source assembly 30 can be fixedly connected to the covering frame 50 or the mounting bracket 70 by any of the following methods: snap-fit, screw, or welding. Correspondingly, the covering frame 50 can also be assembled with the mounting bracket 70 by any of the above connection methods.

[0089] Additionally, it should be noted that the mounting bracket 70 is made of polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS), polypropylene (PP) plastic, or metal, possessing good structural strength and processing performance, and suitable for various assembly processes. The covering skeleton 50 is made of transparent materials such as polycarbonate (PC) or polypropylene (PP) to ensure the overall structural stability while allowing visible light emitted by the light source 31 system to pass through, effectively reducing light flux loss during transmission.

[0090] Please see Figure 12 and Figure 13The light source assembly 30 includes a light guide 33 and a light source 31. The light source 31 can be a light-emitting module; alternatively, it can be a flexible PCB (printed circuit board) with LEDs (light-emitting diodes) arranged on its surface. In some embodiments, to provide multi-color visible light, the light source 31 uses multiple RGB LED beads fixedly disposed on the side of the light guide 33 via a mounting bracket 70, and uses PWM (pulse width modulation) technology to control the color and brightness of the light.

[0091] In this embodiment, the light guide 33 is made of PMMA (polymethyl methacrylate) or PC (polycarbonate). These materials have good light transmittance and light guiding properties, which are beneficial to improving the uniformity of illumination and optical efficiency. Furthermore, it should be noted that the structure of the light guide 33 is not limited to a specific form; it can be a plate-like structure or a strip-like structure, and this invention does not limit it in this regard.

[0092] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
