[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1 to Figure 2As shown, an embodiment of the present invention provides a helmet with a carbon fiber shell integrally formed, the helmet includes: a carbon fiber shell, an energy absorbing layer and an inner lining, a buffer layer, ear cotton and a head cover, wherein the structure from top to bottom is a carbon fiber shell, an efficient energy absorbing buffer layer and a soft and comfortable inner lining (including ear cotton and head cover), the shell is made of selected carbon fiber material, with its high specific strength, high specific modulus, high temperature resistance, corrosion resistance and low density, it provides a solid protective barrier for the head, and the buffer layer is made of EPS, EPP, P4U, P3O and EVA, one of the advanced foam materials, the material can effectively absorb and disperse external impact energy, further improving safety.

[0041] Among them, the specific steps of the helmet one-piece molding process are as follows:

[0042] S1: Design and mold preparation: Carefully design the helmet, including the carbon fiber shell and cooling structure; manufacture high-precision molds to accurately replicate every detail.

[0043] S2: Carbon fiber shell molding: Select carbon fiber cloth and resin, cut and stack, impregnate and solidify, and bake at high temperature to form a solid helmet shell;

[0046] S5: Detail processing and joint end seaming: The joint end is seamed in the groove to enhance stable heat dissipation. Comprehensively check the assembly details to ensure safety without omissions;

[0047] S6: Testing and quality control: Comprehensive and rigorous performance testing and meticulous quality inspection ensure that all indicators of the helmet meet the standards and are of excellent quality.

[0048] The design and mold preparation in S1 refers to the designers carefully conceiving the streamlined shape of the carbon fiber shell, cleverly arranging the holes to optimize the ventilation effect, and planning the distribution of grooves and protrusions to enhance the structural strength and wearing comfort. At the same time, the design of the heat dissipation slots is particularly critical, and their positions must be accurately calculated to ensure effective heat dissipation during high-speed riding or intense exercise. Subsequently, according to these design drawings, advanced manufacturing technology is used to create a high-precision helmet mold.

[0049] The specific steps of forming the carbon fiber shell in S2 are as follows:

[0050] Step 1: Material selection and preparation: Select high-quality carbon fiber cloth and resin materials to ensure excellent material performance and lay a solid foundation for subsequent processing;

[0051] Step 2: Precision cutting and layering: The carbon fiber cloth is carefully cut according to the precisely designed helmet mold shape to ensure that the size of each piece of cloth is accurate. Then, the cut carbon fiber cloth is stacked on the mold layer by layer, and the fiber direction is carefully adjusted to ensure that it meets the design requirements to enhance the strength and durability of the helmet shell;

[0052] Step 3: Resin impregnation and high-temperature curing: The selected resin is evenly applied to the carbon fiber cloth laminate to ensure that the resin can fully penetrate and tightly bond each layer of cloth. Subsequently, the entire structure is placed in an oven and cured at high temperature to allow the resin to tightly bond with the carbon fiber cloth to form a strong and lightweight carbon fiber helmet shell.

[0053] The carbon fiber shell is made with exquisite craftsmanship, selected high-quality materials, precise cutting and lamination to ensure the strength and durability of the helmet. Resin impregnation and high-temperature curing technology make the shell strong and light, perfectly combining high strength and lightweight characteristics. This process not only improves the safety performance of the helmet, but also demonstrates the exquisite craftsmanship level, providing the wearer with top-level safety protection and comfort experience.

[0054] Among them, the production of the S3 buffer layer and lining refers to the careful selection of EPS, EPP, P4U, P3O and EVA high-performance buffer materials, based on safety standards and protection needs, to ensure effective absorption of energy during impact. Subsequently, using advanced foaming molding technology, these materials are precisely molded into a buffer layer that fits the inside of the helmet, which protects the head while keeping it light. At the same time, it is also equipped with soft, skin-friendly lining materials and comfortable ear cotton or head covers, which comprehensively enhance the wearing comfort experience and make every wear a safe enjoyment.

[0055] The carefully crafted cushioning layer and lining are made of high-performance materials and are scientifically foamed to ensure effective energy absorption and head protection while remaining lightweight. The soft, skin-friendly lining and comfortable ear pads / headgear enhance the wearing comfort in all directions, making every wearing experience a double enjoyment of safety and comfort. This design not only meets safety standards, but also reflects meticulous care for the wearer.

[0056] The specific steps of assembling the outer shell and the buffer layer in S4 are as follows:

[0057] Step 1: Carbon fiber shell pretreatment

[0058] The carbon fiber shell is precisely pre-processed, including opening preset holes on the shell. These holes are used to fix the components inside the helmet and meet other design needs. At the same time, grooves and protrusions are processed in specific areas of the shell. These designs not only enhance the structural strength of the shell, but also provide a basis for the subsequent heat dissipation slot processing.

[0059] Step 2: Heat dissipation slot processing

[0060] Next, precision machining tools are used to open heat dissipation slots that penetrate the inner and outer walls of the shell in the grooves processed in step 1. These heat dissipation slots are designed to optimize the ventilation performance of the helmet, effectively discharge the heat and moisture generated by the wearer's head, and improve wearing comfort.

[0061] Step 3: Buffer layer preparation and bonding

[0062] After the heat dissipation slots are processed, the pre-prepared buffer layer (such as EPS, EPPP4U, P3O and EVA materials) is taken out to ensure that the buffer layer has been accurately cut according to the internal shape of the helmet and has good elasticity and buffering performance. Then, the buffer layer is tightly fitted to the inside of the carbon fiber shell. Special attention should be paid to ensure that the buffer layer completely covers all important areas, such as parts of the head that are prone to impact, to achieve the best protection effect.

[0063] Step 4: Check and fix

[0064] Finally, conduct a comprehensive inspection of the bonded buffer layer to ensure that it is tightly combined with the carbon fiber shell without looseness or misalignment. If necessary, use special adhesives or fixings to reinforce the buffer layer. After completing the above steps, the assembly of the helmet's buffer layer and shell is completed. Further testing and adjustments can be carried out to ensure the overall performance and wearing comfort of the helmet.

[0065] Precise assembly of the shell and buffer layer brings multiple advantages. Pre-treatment enhances the structure, and heat dissipation slots optimize ventilation to ensure comfortable wearing. The buffer layer is precisely cut and fitted to enhance the protective effect and protect the head. Comprehensive inspection and fixing ensure quality, and the details are the real thing. This series of meticulous steps not only improves the overall performance of the helmet, but also ensures the safety and comfort of the wearer, making every trip more worry-free.

[0066] Among them, the detail processing and connection end stitching in S5 refers to the in-depth processing of the grooves and protrusions during the fine processing stage of the helmet. Inside the grooves, the connection ends are cleverly stitched along the heat dissipation slots. This design not only enhances the overall structural stability of the helmet, but also effectively improves the ventilation efficiency of the heat dissipation slots, further ensuring the comfort of the wearer. Subsequently, we conducted a comprehensive overall inspection, from the outer shell to the buffer layer, to every detail component, to ensure that all components have been precisely assembled in place without any omissions or errors, aiming to provide the wearer with the highest standards of safety and comfort experience.

[0067] The detail processing and end seams significantly improve the quality of the helmet, strengthen the structural stability and optimize the heat dissipation performance, bringing a more comfortable and safe experience to the wearer. A comprehensive overall inspection ensures that every link is accurate, from the shell to the buffer layer, the details are true, showing the unremitting pursuit of quality. This series of careful design and strict inspection makes the helmet a trusted partner for the wearer, whether in daily riding or extreme sports, it can provide the highest standard of protection and enjoyment.

[0068] The details of the test and quality control in S6 are as follows:

[0069] Step 1: Comprehensive performance test

[0070] The helmets are subjected to comprehensive performance tests, including but not limited to strength tests (simulating collision impacts to verify their tolerance), stability tests (ensuring that the helmets are not easy to shake or fall off under various wearing conditions), high temperature tests (assessing their durability in high temperature environments), corrosion tests (checking their resistance to common chemicals), and comfort tests (assessing their fit to the head, breathability, and overall comfort through actual wearing experience). These tests are designed to ensure that all performance indicators of the helmets meet design requirements and relevant industry standards.

[0071] Step 2: Detailed quality inspection

[0072] After completing the performance test, the quality inspection phase begins. This phase focuses on a comprehensive review of the appearance, size, and details of the helmet. The appearance inspection includes confirming that the helmet surface is smooth and flawless, the color is uniform, and the logo is clear; the size inspection ensures that the helmet is ergonomically designed and suitable for wearers of different head shapes; the detail inspection covers sewing technology, material splicing, accessory installation, and other aspects, striving to achieve exquisite and perfect standards in every aspect.

[0073] Step 3: Comprehensive evaluation and improvement

[0074] Finally, the helmet is comprehensively evaluated based on the performance test results and quality inspection feedback. If any problems that do not meet the design requirements and standards are found, an improvement process will be immediately initiated, including but not limited to adjusting the production process, replacing high-quality materials, optimizing the structural design, etc., until the helmet meets the highest quality standards in all aspects.

[0075] Implementing testing and quality control processes can ensure that the helmets reach excellent levels in terms of strength, stability, high temperature resistance, corrosion resistance and comfort, and meet strict design requirements and industry standards. Through meticulous quality inspections, the perfection of product appearance and detail processing is improved, and market competitiveness is enhanced.
