Description

Technical Field

[0001] This application relates to the field of safety protection equipment technology, and in particular to a BMC molded lightweight safety shoe toe cap. Background Technology

[0002] The toe cap of safety shoes, often called the "steel toe" or "protective toe cap," is a crucial core protective component. It is generally made of high-strength, impact-resistant materials and has excellent protective performance. In complex and ever-changing work environments, such as construction sites where heavy objects may fall at any time, or in factory workshops where machines may squeeze or collide during operation, the toe cap of safety shoes can effectively resist these external forces, building a solid safety barrier for the toes, significantly reducing the possibility of toe injuries, and effectively ensuring the safety of workers' feet during work.

[0003] Existing protective headgear is generally made of a single metal material, which is not only heavy, increasing the burden of wearing it, but also expensive, increasing investment costs. Utility Model Content

[0004] The purpose of this application is to provide a BMC molded lightweight safety shoe protective toe cap, which has the advantages of being lightweight, reducing the burden of wearing, improving wearing comfort, being easy to mold, being able to be mass-produced, having high production efficiency, having outstanding mechanical properties, being resistant to aging and corrosion, and having a moderate cost, thus solving the problems mentioned in the background art.

[0005] The technical solution of the BMC molded lightweight safety shoe protective toe cap provided in this application is as follows: A BMC molded lightweight safety shoe protective toe cap includes a BMC toe cap, wherein the BMC toe cap is in the shape of an arc dome, and the shape of the BMC toe cap is adapted to the front contour of the human foot.

[0006] The BMC headgear includes a headgear body, the outer surface of which is provided with multiple reinforcing ribs, and the interior of which is provided with multiple heat dissipation holes.

[0007] By adopting the above technical solution and incorporating BMC material into the toe cap, it is possible to leverage the unique density characteristics of BMC material. Compared to traditional materials used for toe caps in safety shoes, this design effectively reduces the weight of the toe cap while maintaining sufficient strength and protective performance. BMC material also exhibits good flowability and moldability, allowing for one-time molding under high temperature and pressure, facilitating large-scale industrial production and significantly improving production efficiency to meet the substantial market demand for safety shoes. After molding, the BMC material has a uniform and dense internal structure with high strength, hardness, and toughness, effectively dispersing and withstanding external impact forces, providing reliable protection for the forefoot, and reducing the risk of injury. Furthermore, BMC material demonstrates excellent aging resistance. The BMC material boasts excellent chemical and corrosion resistance, extending the lifespan of the toe cap and safety shoes. Its relatively low raw material and production costs allow for effective cost control while meeting safety requirements, resulting in a high cost-performance ratio in the market. The BMC toe cap, designed with an arc-shaped dome that conforms to the contours of the foot, provides a close fit and enhances comfort. Reinforcing ribs further strengthen the toe cap's structure, ensuring it remains intact even under extreme impacts, providing a more reliable protective barrier for the feet. Ventilation holes promote airflow, reducing stuffiness and discomfort from prolonged wear and improving the overall wearing experience.

[0008] Preferably, the reinforcing ribs are arranged radially.

[0009] By adopting the above technical solution, this arrangement can evenly diffuse the impact force from the point of impact to the surrounding area, quickly dispersing the local impact force to the entire headgear structure, further enhancing the headgear's ability to withstand impacts in different directions, improving the overall stability of the headgear structure, and providing more comprehensive and reliable protection for the front of the feet.

[0010] Preferably, the reinforcing rib is adapted to the shape of the headpiece body.

[0011] By adopting the above technical solution, this adaptive design enables the reinforcing ribs and the headband body to work together better. When subjected to external impact, the reinforcing ribs can follow the outline of the headband body to more effectively transmit and disperse the impact force, avoiding stress concentration caused by shape mismatch, thereby enhancing the structural strength and impact resistance of the headband and better protecting the feet.

[0012] Preferably, the reinforcing rib is integrally formed with the head cover body.

[0013] By adopting the above technical solution, the one-piece molding process ensures that there are no gaps between the reinforcing ribs and the headband body, eliminating weak points caused by insecure connections. When subjected to impact, the two can work together as a whole to bear the force, avoiding protective failure caused by loosening or breakage of the connection. This greatly improves the structural integrity and reliability of the headband, providing more durable protection for the feet.

[0014] Preferably, the heat dissipation holes are arranged in two layers at equal intervals.

[0015] By adopting the above technical solution, the two layers of equidistant heat dissipation holes increase the airflow path and flow inside the headgear, further optimizing the heat dissipation effect and improving wearing comfort.

[0016] Preferably, the bottom of the headgear body is integrally formed with a horizontally arranged edge support plate.

[0017] By adopting the above technical solution, the horizontally set edge support plate greatly increases the support area of ​​the toe cap, making it more fully and stably in contact with the shoe body. When walking, running or being impacted by external forces, the larger support area can distribute the pressure more evenly, avoid local stress concentration, and improve the stability of the toe cap.

[0018] Preferably, the BMC head is formed by high temperature and high pressure in a single molding process.

[0019] By adopting the above technical solution, one-time molding avoids the structural defects and performance degradation that may be caused by multiple processing, ensuring that the toe cap has high strength, hardness and toughness, and can more effectively disperse and withstand external impact forces, providing reliable protection for the front of the foot. At the same time, the high temperature and high pressure one-time molding process is easy to automate, improving production efficiency and product quality stability.

[0020] Preferably, the outer surface of the BMC cap is coated with a polyurethane coating.

[0021] By adopting the above technical solution, the polyurethane coating has good wear resistance, corrosion resistance and scratch resistance. After being coated on the outer surface of the BMC cap, it can effectively protect the cap from external environmental erosion and friction, optimize the cap's aging resistance and corrosion resistance, and extend the cap's service life.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This lightweight BMC molded safety shoe toe cap utilizes BMC material. BMC has unique density characteristics, and compared to traditional materials used in safety shoe toe caps, it effectively reduces the weight of the toe cap while maintaining sufficient strength and protective performance. BMC material has good flowability and moldability, allowing for one-time molding under high temperature and pressure, facilitating large-scale industrial production and significantly improving production efficiency to meet the large market demand for safety shoes. After molding, the BMC material has a uniform and dense internal structure with high strength, hardness, and toughness, effectively dispersing and withstanding external impact forces, providing reliable protection for the forefoot and reducing the risk of injury. BMC material also exhibits excellent flowability and moldability. The BMC material's excellent aging and corrosion resistance extends the lifespan of the toe cap and safety shoes. Its relatively low raw material and production costs allow for effective cost control while meeting safety requirements, resulting in a high cost-performance ratio in the market. The BMC toe cap's curved dome shape conforms to the contours of the foot, ensuring a close fit and improved comfort. Reinforcing ribs further enhance the toe cap's structural strength, allowing it to withstand extreme impacts and providing a more reliable protective barrier. Ventilation holes promote airflow, reducing stuffiness and discomfort from prolonged wear and improving the overall wearing experience. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A BMC molded lightweight safety shoe toe cap, referring to... Figure 1 , Figure 2 and Figure 3 It includes BMC headgear 1, which is in the shape of an arc dome and its shape is adapted to the front contour of the human foot.

[0033] In terms of protective performance, the arched dome structure acts like a sturdy shield, evenly distributing external impact forces across the entire surface of the headgear, avoiding localized stress concentration, effectively enhancing the headgear's impact resistance, providing reliable protection for the front of the feet, and reducing the risk of injury.

[0034] In terms of comfort, the design that fits the contour of the front of the foot ensures that the toe box fits snugly against the foot, reducing friction and movement between the toe box and the foot during walking or exercise. This avoids the squeezing and discomfort caused by a poor fit, and makes it less tiring for users to wear for extended periods.

[0035] In addition, this fitted design enhances the overall aesthetics of the safety shoe, making the shoe look more streamlined and natural.

[0036] The bottom of the toe cap body 101 is integrally formed with a horizontally arranged edge support plate 104. The horizontally arranged edge support plate 104 greatly increases the support area of ​​the toe cap, making it more fully and stably in contact with the shoe body. When walking, running or being impacted by external forces, the larger support area can distribute the pressure more evenly, avoid local stress concentration, and improve the stability of the toe cap.

[0037] The outer surface of the BMC cap 1 is coated with a polyurethane coating. The polyurethane coating has good wear resistance, corrosion resistance and scratch resistance. After being coated on the outer surface of the BMC cap 1, it can effectively protect the cap from external environmental erosion and friction, optimize the cap's aging resistance and corrosion resistance, and extend the cap's service life.

[0038] Example 2: A BMC molded lightweight safety shoe toe cap, referring to... Figure 3 , Figure 4 and Figure 5 The BMC headgear 1 includes a headgear body 101, and the outer surface of the headgear body 101 is provided with a plurality of reinforcing ribs 102.

[0039] The reinforcing ribs 102 are arranged radially. This arrangement allows the impact force to be evenly diffused from the point of impact to the surrounding area, quickly dispersing the impact force received locally to the entire headgear structure. This further enhances the headgear's ability to withstand impacts in different directions, improves the overall stability of the headgear structure, and provides more comprehensive and reliable protection for the front of the feet.

[0040] The reinforcing rib 102 is adapted to the shape of the headgear body 101. This adaptation design enables the reinforcing rib 102 and the headgear body 101 to work together better. When subjected to external impact, the reinforcing rib 102 can follow the outline of the headgear body 101 to more effectively transmit and disperse the impact force, avoid stress concentration caused by shape mismatch, thereby enhancing the structural strength and impact resistance of the headgear and better protecting the safety of the feet.

[0041] The reinforcing rib 102 is integrally formed with the headband body 101. The integral forming process ensures that there are no connection gaps between the reinforcing rib 102 and the headband body 101, eliminating weak points caused by weak connections. When subjected to impact, the two can share the force as a whole, avoiding protective failure caused by loosening or breakage of the connection. This greatly improves the structural integrity and reliability of the headband, providing more durable protection for the feet.

[0042] The main body 101 of the head has multiple heat dissipation holes 103 inside.

[0043] The heat dissipation holes 103 are arranged in two layers at equal intervals. The two layers of equally spaced heat dissipation holes 103 increase the airflow path and flow inside the headgear, further optimize the heat dissipation effect, and improve the wearing comfort.

[0044] BMC headband 1 is formed by high temperature and high pressure in one molding process. One molding avoids the structural defects and performance degradation that may be caused by multiple processing, ensuring that the headband has high strength, hardness and toughness, and can more effectively disperse and withstand external impact forces, providing reliable protection for the front of the foot. At the same time, the high temperature and high pressure one molding process is easy to automate, improving production efficiency and product quality stability.

[0045] It should be noted that BMC, or Bulk Molding Compound, is mainly composed of special yarn, unsaturated resin, low-shrinkage additives, fillers, and various auxiliaries. The material cost is relatively low, and it can be molded in one step using high-temperature and high-pressure molding technology. The production process cost is also relatively low, the production efficiency is high, and it is easy to achieve large-scale industrial production.

[0046] The implementation principle of this application embodiment is as follows: BMC material has unique density characteristics. Compared with traditional materials used for safety shoe toe caps, it can effectively reduce the weight of the toe cap while ensuring sufficient strength and protective performance, making the safety shoe lighter overall, reducing the burden on the user's feet, and improving wearing comfort. BMC material has good fluidity and moldability, allowing it to be molded into an arc-shaped dome that conforms to the contour of the front of the human foot in one piece under high temperature and high pressure. This facilitates large-scale industrial production, greatly improves production efficiency, and meets the large market demand for safety shoes. The BMC toe cap 1 is set as an arc-shaped dome that conforms to the contour of the front of the human foot. The design allows for a close fit to the forefoot, further enhancing wearing comfort. After molding, the BMC material has a uniform and dense internal structure, possessing high strength, hardness, and toughness. It effectively disperses and withstands external impacts, providing reliable protection for the forefoot and reducing the risk of injury. BMC material also exhibits excellent aging and corrosion resistance, extending the lifespan of the toe cap and safety shoe. The raw material and production costs of BMC material are relatively low, effectively controlling production costs while meeting safety requirements, resulting in a high cost-performance ratio in the market. The toe cap body 101 features an integrated horizontal edge support plate 104 at the bottom. This significantly increases the contact area between the toe cap and the shoe body. During walking, running, or impact, the larger support area distributes pressure more evenly, preventing localized stress concentration and improving the stability of the toe cap within the shoe. The polyurethane coating on the outer surface of the BMC toe cap 1, with its excellent wear resistance, corrosion resistance, and scratch resistance, forms a robust protective film. This protective film effectively resists external environmental erosion and friction, reducing damage to the BMC material from external factors, optimizing the toe cap's aging and corrosion resistance, and thus extending its service life. The outer surface of the toe cap body 101 features radially arranged reinforcements that are adapted to the shape of the toe cap body 101. The reinforcing rib 102, when subjected to external impact, can evenly diffuse the impact force from the point of impact to the surrounding area along the outline of the toe cap body 101, quickly dispersing it throughout the entire toe cap structure. This greatly improves the structural integrity and reliability of the toe cap, providing more durable and comprehensive protection for the feet. The two layers of equidistantly arranged heat dissipation holes 103 inside the toe cap body 101 increase the airflow path and volume inside the toe cap. When the user wears the safety shoes, the heat and moisture generated by the feet can flow more smoothly between different layers through these heat dissipation holes 103, reducing the stuffiness and discomfort caused by prolonged wear and improving the overall wearing experience.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
