Description

Technical Field

[0001] This utility model relates to the field of helmets, specifically to a foil-forged textured carbon cloth. Background Technology

[0002] As an essential piece of equipment in sports such as cycling and motorcycling, as well as in the field of safety protection, the core function of helmets is to provide effective protection for the user's head. With the advancement of technology and the improvement of people's safety awareness, the design and manufacturing of helmets are constantly evolving, striving to meet the diverse needs of lightweight, comfort, and aesthetics while ensuring safety.

[0003] Currently, in bicycles and motorcycles, helmet shells are generally made of carbon fiber through stamping and heat curing, resulting in helmet shells that combine high strength and lightweight. However, despite the excellent performance of carbon fiber helmets, existing carbon fiber helmets, made solely of carbon fiber, present the following technical challenges in practical use:

[0004] First, pure carbon fiber has relatively poor abrasion resistance. Long-term exposure to harsh environments (such as wind, sand, and rain) will cause wear on the helmet surface, thus affecting the helmet's lifespan and appearance. Second, because carbon fiber itself is black or dark gray, it is difficult to achieve rich color variations through traditional dyeing or coating processes. Therefore, pure carbon fiber products have relatively limited color options, which to some extent restricts the appearance design of helmets and fails to meet consumers' strong demand for personalized and fashionable designs.

[0005] In summary, it is necessary to develop a foil-forged textured carbon cloth to improve the wear resistance and aesthetics of carbon cloth. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a foil-forged textured carbon cloth, which can at least solve the technical problem of how to improve the wear resistance and aesthetics of carbon cloth.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a foil-forged textured carbon cloth, comprising:

[0010] Carbon fiber base layer, which is configured as the innermost layer of the helmet shell;

[0011] A foil color layer is fixed to the outside of the carbon fiber base layer, and the foil color layer is different in color from the carbon fiber base layer.

[0012] The transparent protective layer includes a transparent abrasion-resistant layer and a transparent heat-resistant layer. The transparent heat-resistant layer is fixed to the outside of the foil color layer, and the transparent abrasion-resistant layer is fixed to the outside of the transparent heat-resistant layer.

[0013] Further, the aforementioned foil color layer is any one of colored gold foil, aluminum foil, or alloy aluminum foil, and the thickness of the foil color layer is 0.01mm to 0.1mm.

[0014] Furthermore, the aforementioned foil-forged carbon cloth also includes a pattern layer, which is fixed between the transparent protective layer and the foil color layer. The pattern layer has several gaps for the foil color layer to show through.

[0015] Further configuration: the aforementioned pattern layer includes a forged texture layer and a transparent adhesive layer. The forged texture layer includes multiple bundles of short fibers, which are randomly arranged on the outside of the transparent adhesive layer to form a forged texture structure. Gaps of varying sizes are formed between the short fibers. The transparent adhesive layer is fixed on the outside of the foil color layer.

[0016] Further configuration: the aforementioned carbon fiber base layer includes a positive 45-degree carbon fiber layer and a negative 45-degree carbon fiber layer, which are bonded together.

[0017] Further, the aforementioned transparent wear-resistant layer is any one of a transparent polyamide resin layer, a transparent polyurethane layer, or a transparent PVC layer, and the thickness of the transparent wear-resistant layer is 0.05mm to 0.2mm.

[0018] Furthermore, the aforementioned transparent heat-resistant layer is a transparent epoxy resin layer.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the foil-forged textured carbon cloth provided by this utility model has the following beneficial effects:

[0021] 1. The foil forged carbon cloth provided by this utility model uses a carbon fiber base layer as the basic structural layer of the foil forged carbon cloth, which can ensure the structural strength of the imitation forged carbon cloth for helmets and is the main load-bearing layer for the helmet shell to withstand external impact. On this basis, the combination of foil color layer can not only enhance the strength and rigidity of the carbon cloth, but also enrich the appearance color of the helmet, making the helmet shell more aesthetically pleasing and meeting consumers' demand for personalized and fashionable appearance.

[0022] 2. The transparent protective layer of the forged carbon fiber foil consists of a transparent abrasion-resistant layer and a transparent heat-resistant layer. The transparent abrasion-resistant layer provides surface protection, effectively improving the abrasion resistance of the outer surface of the carbon fiber, making the helmet surface less prone to scratches. This protects the foil color layer and carbon fiber base layer from wear, preventing them from affecting the helmet's aesthetics and lifespan, resulting in a helmet shell with excellent appearance quality that meets consumer aesthetic demands. The transparent heat-resistant layer improves the heat resistance of the carbon fiber, preventing the foil color layer and transparent abrasion-resistant layer from delaminating due to heat. Both the transparent abrasion-resistant layer and the transparent heat-resistant layer are transparent and will not affect the presentation of the foil color layer. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] A foil-forged textured carbon cloth is used to address the problem of how to improve the wear resistance and aesthetics of carbon cloth.

[0032] See Figure 1 As shown, Figure 1 The image shown is a cross-sectional view of the foil-forged carbon cloth in the embodiment. The foil-forged carbon cloth includes a carbon fiber base layer 1, a foil color layer 2, and a transparent protective layer 3.

[0033] The carbon fiber base layer 1 is configured as the innermost layer of the helmet shell.

[0034] The foil color layer 2 is bonded and fixed to the outside of the carbon fiber base layer 1, and the foil color layer 2 is different in color from the carbon fiber base layer 1.

[0035] The transparent protective layer 3 includes a transparent wear-resistant layer 31 and a transparent heat-resistant layer 32. The transparent heat-resistant layer 32 is bonded and fixed to the outside of the foil color layer 2, and the transparent wear-resistant layer 31 is bonded and fixed to the outside of the transparent heat-resistant layer 32.

[0036] The above technical solution uses carbon fiber base layer 1 as the basic structural layer of the foil forged carbon cloth, which can ensure the structural strength of the imitation forged carbon cloth for the helmet and is the main load-bearing layer for the helmet shell to withstand external impact. On this basis, the combination of foil color layer 2 can not only enhance the strength and rigidity of the carbon cloth, but also enrich the appearance color of the helmet, making the helmet shell more aesthetically pleasing and meeting consumers' demand for personalized and fashionable appearance. Furthermore, the transparent protective layer 3 of the forged carbon fiber fabric consists of a transparent abrasion-resistant layer 31 and a transparent heat-resistant layer 32. The transparent abrasion-resistant layer 31 provides surface protection, effectively improving the abrasion resistance of the outer surface of the carbon fiber fabric, making the outer surface of the helmet made of the carbon fiber fabric less prone to scratches. This protects the foil color layer 2 and the carbon fiber base layer 1 from wear, so as not to affect the aesthetics and service life of the helmet, giving the helmet shell a good appearance quality and meeting consumers' aesthetic needs. The transparent heat-resistant layer 32 improves the heat resistance of the carbon fiber fabric, making it less likely for the foil color layer 2 and the transparent abrasion-resistant layer 31 to delaminate due to heat. Both the transparent abrasion-resistant layer 31 and the transparent heat-resistant layer 32 are transparent and will not affect the presentation of the foil color layer 2.

[0037] See Figure 1 As shown, in one embodiment of the foil color layer 2, the foil color layer 2 is any one of colored gold foil, aluminum foil, or alloy aluminum foil, and the thickness of the foil color layer 2 is 0.01mm to 0.1mm. The foil color layer 2 can be made of any color of gold foil, aluminum foil, or alloy aluminum foil, etc., as needed. Since gold foil, aluminum foil, and alloy aluminum foil are all reflective, the foil color layer 2 formed by using gold foil, aluminum foil, or alloy aluminum foil can not only enhance the strength and rigidity of the composite carbon cloth and enrich the appearance color of the helmet, but also make the helmet visible at night and improve the safety of the helmet. The thickness of 0.01mm to 0.1mm can balance the weight and strength of the carbon cloth.

[0038] See Figure 1 As shown, based on any of the above embodiments, the foil-forged carbon fabric further includes a pattern layer 4, which is bonded and fixed between the transparent protective layer 3 and the foil color layer 2. The pattern layer 4 has several gaps 5 for the foil color layer 2 to show through. Thus, the combination of the pattern layer 4 and the foil color layer 2 can further enhance the aesthetics of the helmet shell and meet consumers' demand for personalized and fashionable appearance.

[0039] See Figure 1 As shown, in one embodiment of the pattern layer 4, the pattern layer 4 includes a forged texture layer 41 and a transparent adhesive layer 42. The forged texture layer 41 includes multiple bundles of short fibers, which are randomly distributed on the outside of the transparent adhesive layer 42 to form a forged texture structure, with gaps 5 of varying sizes formed between the short fibers. The transparent adhesive layer 42 is bonded and fixed to the outside of the foil color layer 2. Thus, when manufacturing the forged texture layer 41, short fibers can be randomly laid on the transparent adhesive layer 42 to form an aesthetically pleasing forged texture layer 41 on the outside of the transparent adhesive layer 42. The forged texture layer 41 formed in this way not only increases the aesthetic value of the helmet and provides a rich visual effect, but also improves the impact resistance of the composite carbon cloth to a certain extent. The texture dispersion effect reduces the damage caused by direct impact from external forces. The transparent adhesive layer 42 can not only fix the shape of the forged texture layer 41 and bond the forged texture layer 41 between the transparent protective layer 3 and the foil color layer 2, but also allow the color of the foil color layer 2 to show through, complementing the forged texture and forming a personalized pattern, which increases the aesthetic value of the helmet and provides a rich visual effect.

[0040] See Figure 1 As shown, in one embodiment of the carbon fiber base layer 1, the carbon fiber base layer 1 includes a positive 45-degree carbon fiber layer 11 and a negative 45-degree carbon fiber layer 12, which are bonded together. Thus, the foil-forged textured carbon cloth, through the positive 45-degree carbon fiber layer 11 and the negative 45-degree carbon fiber layer 12, can improve its mechanical properties such as axial tensile strength and radial tensile strength, thereby ensuring the structural strength of the helmet-making carbon cloth with a forged texture, and enabling the helmet shell made of this carbon cloth to withstand greater external impact.

[0041] The aforementioned short fibers, positive 45-degree carbon fiber layer 11, and negative 45-degree carbon fiber layer 12 can all use existing carbon fiber bundles, but the lengths of the carbon fiber bundles in both positive 45-degree carbon fiber layer 11 and negative 45-degree carbon fiber layer 12 are much greater than the lengths of the short fibers.

[0042] See Figure 1 As shown, in one embodiment of the transparent abrasion-resistant layer 31, the transparent abrasion-resistant layer 31 is any one of a transparent polyamide resin layer, a transparent polyurethane layer, or a transparent PVC layer, and the thickness of the transparent abrasion-resistant layer 31 is 0.05mm to 0.2mm. Thus, the transparent polyamide resin layer, transparent polyurethane layer, and transparent PVC layer all possess high transparency and high abrasion resistance. The transparent abrasion-resistant layer 31 made in this way can enhance the abrasion resistance of the helmet shell, effectively resisting daily wear and tear, while maintaining the overall transparency and gloss of the composite carbon fabric, allowing the patterns or colors on the inner side to be clearly displayed without being affected by wear.

[0043] See Figure 1 As shown, in one embodiment of the transparent heat-resistant layer 32, the transparent heat-resistant layer 32 is a transparent epoxy resin layer. Thus, the transparent epoxy resin layer is heat-resistant and has strong adhesion. The transparent heat-resistant layer 32 thus formed can firmly fix the transparent wear-resistant layer 31 and the foil color layer 2, and improve the heat resistance of the foil forged carbon cloth, making it less likely for the foil color layer 2 and the transparent wear-resistant layer 31 to delaminate due to heat. Furthermore, the transparent epoxy resin layer also has high transparency, allowing the inner patterns or colors to be clearly displayed without being affected by wear.

[0044] All the aforementioned layers can be bonded and fixed using any of the adhesives selected from phenolic resin, epoxy resin, and unsaturated polyester resin. However, all adhesives (including the transparent adhesive layer 42) between the transparent protective layer 3 and the foil color layer 2 or pattern layer 4 must be transparent to avoid affecting the presentation of the foil color layer 2 and / or pattern layer 4. The transparent adhesive layer 42 can also be made of transparent epoxy resin, which can prevent the foil color layer 2 and pattern layer 4 from delaminating due to heat.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
