Abstract
Description
Technical Field
[0001] This utility model relates to a light-transmitting carbon fiber component, particularly a light-transmitting carbon fiber component that can be used in conjunction with a light source to create a patterned luminous visual effect. Background Technology
[0002] As living standards improve, people's pursuit of visual experiences also increases. In the automotive industry, in order to make the appearance of cars more high-end and technological, manufacturers have developed a car component that, in conjunction with changes in lighting, can present a visual effect of illuminated patterns.
[0003] Traditionally, automotive components are formed by creating a pattern layer on one side of a light-transmitting substrate. The pattern layer has a light-shielding part and a light-transmitting part. The automotive component can form a pattern by combining the light-shielding part and the light-transmitting part of the pattern layer, and emit light with the help of a light source, so that the light can pass through only the light-transmitting part of the pattern layer and present the effect of the pattern emitting light on the light-transmitting substrate.
[0004] The aforementioned automotive parts are made of a light-transmitting substrate. However, due to the limitations of the material, the light-transmitting substrate may have insufficient strength in its application, which leads to a greater limitation in its application. Therefore, in order to provide sufficient strength and at the same time achieve the purpose of displaying luminous patterns, opaque materials are now used as substrates, and several holes are formed on the opaque substrate by CNC or punching, so that light can pass through the holes of the opaque substrate to form the effect of pattern luminescence.
[0005] However, depending on the application of automotive components, their requirements for strength and weight vary. Taking aerodynamic components that require high strength and extremely light weight as an example, these components are not suitable for using heavy substrates. Therefore, if high-strength and lightweight carbon fiber is used as the substrate, although it can overcome the problem of excessive weight of current substrates, the high hardness, wear resistance and heat resistance of carbon fiber cause great wear on the cutting tools during drilling, which greatly increases the production cost. In addition, the edges of the processed area are prone to forming burrs and rough edges, which not only fail to achieve the desired light transmission effect, but may also damage the structural strength.
[0006] Therefore, the goal of the applicant of this utility model is to find out how to make a car part that can transmit light using carbon fiber as the base material, so that the car part can have the characteristics of high strength and lightweight while also having a luminous visual effect. Utility Model Content
[0007] The technical problem to be solved by this invention is that current carbon fiber components are difficult to process and are prone to burrs, making it difficult to achieve light transmission.
[0008] The technical solution of this utility model is as follows: To achieve the aforementioned objective, the light-transmitting carbon fiber component of this utility model can be used with a light source, and the light-transmitting carbon fiber component comprises: A carbon fiber substrate has a display side and a mating side formed on opposite sides, and has a plurality of holes formed by laser processing. The mating side corresponds to the light source, and the holes are arranged at intervals along a first direction and a second direction, respectively. A protective layer is disposed on the display side of the carbon fiber substrate.
[0009] This invention relates to a translucent carbon fiber component that can be used in conjunction with a light source to create a patterned luminous visual effect. The translucent carbon fiber component utilizes laser-processed holes in the carbon fiber substrate to allow light emitted from the light source to enter the substrate, pass through the holes, and then penetrate the protective layer, thus creating the luminous effect. This allows the translucent carbon fiber component to possess both high strength and lightweight properties, while simultaneously presenting a personalized patterned luminous visual aesthetic.
[0010] In addition, using laser processing to melt or burn out several holes can significantly reduce the occurrence of burrs or residues after processing, and overcome the problem of easy wear of traditional processing tools, thereby reducing production and manufacturing costs.

[0016] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.
[0017] Please see Figure 1 and Figure 4This is a preferred embodiment of the light-transmitting carbon fiber component of the present invention, which can be used with a light source 40. The light-transmitting carbon fiber component includes a carbon fiber substrate 10 and a protective layer 20.
[0018] like Figure 2 and Figure 3 As shown, a display side 11 and a mating side 12 are formed on opposite sides of the carbon fiber substrate 10, and a plurality of holes 13 formed by laser processing are provided. The mating side 12 can correspond to the light source 40, and the holes 13 are arranged at intervals along a first direction X and a second direction Y.
[0019] like Figure 3 As shown, the protective layer 20 is disposed on the display side 11 of the carbon fiber substrate 10.
[0020] like Figure 4 As shown, the light-transmitting carbon fiber component includes a light-diffusing layer 30, which is disposed on the mating side 12 of the carbon fiber substrate 10 and corresponds to the light source 40.
[0021] like Figure 2 As shown, the diameter a of each of the holes 13 is between 0.02 mm and 0.4 mm; in addition, the spacing b and c of the holes 13 is greater than 0.3 mm.
[0022] like Figure 2 As shown, the carbon fiber substrate 10 has a fiber weft direction 14, and the first direction X can be tilted relative to the fiber weft direction 14 to form an angle θ between 2° and 88°, and the holes 13 arranged along the second direction Y are staggered.
[0023] like Figure 2 As shown, the spacing b of the holes 13 arranged along the first direction X and the spacing c of the holes 13 arranged along the second direction Y are not equal.
[0024] like Figure 4 As shown, in use, the light-transmitting carbon fiber component of this utility model allows light emitted from the light source 40 to enter the light-diffusing layer 30. Since the light-diffusing layer 30 is made of materials such as PMMA, PC, ABS, or PP that can uniformly distribute light, the light can be evenly distributed in the light-diffusing layer 30. Furthermore, due to the opaque nature of the carbon fiber substrate 10, the light can be blocked, allowing the light to pass through only the holes 13 and then through the protective layer 20, thus creating the visual effect of light emanating from the holes 13.
[0025] The holes 13 can be customized according to user needs and arranged into different styles such as text, symbols or totems. The light source 40 can be a direct light source such as a light module or sunlight, or an indirect light source such as reflected light. This allows the light source 40 to be set to different settings according to user needs. By combining the variability of the arrangement of the holes 13 with the versatility of the light source 40, a personalized and unique lighting effect can be created.
[0026] In addition, the protective layer 20 can protect the carbon fiber substrate 10 from direct contact with external substances such as sunlight, rain or dust, thereby improving the weather resistance of the light-transmitting carbon fiber component and further extending its service life.
[0027] like Figure 2 As shown in the preferred embodiment of the light-transmitting carbon fiber component of this utility model, the aperture a of the hole 13 is between 0.04mm and 0.1mm, and the spacing b and c of the hole 13 is greater than 0.3mm. Therefore, when the light source 40 disappears, the hole 13 can have a certain degree of concealment, so that the light-transmitting carbon fiber component can maintain the integrity and aesthetics of its appearance.
[0028] like Figure 5 As shown, the steps for manufacturing the light-transmitting carbon fiber component are to sequentially perform a pre-forming step S1, a laser drilling step S2, and a protective layer processing step S3; in addition, the method for manufacturing the light-transmitting carbon fiber component may further include a light-diffusing layer processing step S4.
[0029] In the preforming step S1, carbon fiber material is preformed into the carbon fiber substrate 10. The preforming method can be to first impregnate the carbon fiber material with resins such as epoxy resin, PC, PP, etc., then cut it and place it in a mold with a single or multi-layer structure, and finally cure it under high temperature and pressure. In this way, the carbon fiber substrate 10 of different shapes can be preformed according to the requirements.
[0030] In the laser drilling step S2, the carbon fiber substrate 10 is laser-processed to form the hole 13. The laser processing involves focusing a high-energy laser beam onto the surface of the carbon fiber substrate 10. The carbon fiber substrate 10 absorbs the laser energy and is rapidly heated to a melting or vaporizing state, thereby melting or burning out the hole 13. This improves the problem of burrs or rough edges easily forming on the edges of carbon fiber materials during processing, ensuring that the hole 13 has good light transmission and does not cause wear on processing tools, thus significantly reducing manufacturing costs.
[0031] In addition, such as Figure 2As shown, by controlling the parameters of laser processing, the aperture a of each hole 13 can be controlled to be between 0.02mm and 0.4mm, preferably between 0.04mm and 0.1mm, and the spacing b and c of the holes 13 can be greater than 0.3mm. This allows for precise control of the aperture a and spacing b and c of the holes 13, reducing the impact of heat accumulation and splash contamination, and preventing the holes 13 from becoming clogged and difficult to clean.
[0032] Furthermore, such as Figure 2 As shown, the first direction X can be further controlled to be tilted relative to the fiber weft direction 14 of the carbon fiber substrate 10, and the resulting included angle θ is between 2° and 88°. The laser drilling path is to first process a row of holes 13 in the first direction X, then move towards the second direction Y, then process a row of holes 13 in the opposite direction of the first direction X, and then move towards the second direction Y again, and repeat the path sequentially until all holes 13 are processed. This makes the holes 13 arranged along the second direction Y staggered. In addition, depending on different pattern changes, the spacing b of the holes 13 arranged along the first direction X and the spacing c of the holes 13 arranged along the second direction Y can be selectively controlled to be unequal, so that the holes 13 can be staggered from the fiber direction, thereby effectively preventing the holes 13 from cutting the fibers into small short fibers, and preventing burrs from falling out and clogging the holes 13.
[0033] In the protective layer processing step S3, the display side 11 of the carbon fiber substrate 10 is processed to form the protective layer 20. During the protective layer processing step S3, the protective layer 20 can be uniformly attached to the display side 11 of the carbon fiber substrate 10 through processing methods such as printing, spraying, film application, dip coating, or spray coating. For example, the protective layer 20 can cover the holes 13 and be translucent, allowing the holes 13 to pass through without obstruction. Alternatively, the protective layer 20 may not cover the holes; in this case, it is necessary to control air bubbles or impurities to prevent them from blocking the holes 13 and affecting their light transmission effect.
[0034] In the homogenization layer processing step S4, the mating side 12 of the carbon fiber substrate 10 is processed to form the homogenization layer 30. When performing the homogenization layer processing step S4, the homogenization layer 30 can be stably attached to the mating side 12 of the carbon fiber substrate 10 by means of processing methods such as applying glue, welding or hot pressing.
[0035] In summary, the translucent carbon fiber component of this invention, through the holes 13 formed by laser processing on the carbon fiber substrate 10, allows light emitted from the light source 40 to enter the carbon fiber substrate 10 and then pass through the holes 13, penetrating the protective layer 20, thereby creating a visual effect of light emanating from the holes 13. This enables the translucent carbon fiber component to possess both high strength and lightweight properties, while also presenting a visually appealing aesthetic of personalized patterned light emission.
[0036] In addition, using laser processing to melt or burn out several holes 13 can significantly reduce the occurrence of burrs or residues after processing, and overcome the problem of easy wear of traditional processing tools, thereby reducing the cost of production and manufacturing.
