[0002] Safety shoes are a type of professional footwear with protective functions, designed to protect the wearer's feet from injury, especially in hazardous environments such as industry, construction, and manufacturing.

[0003] To achieve the above functions, a prior art Chinese patent (publication number: CN220024276U) discloses a safety shoe, relating to the field of safety shoe technology. The device body includes a shoe upper, sole, anti-impact component, insole, auxiliary component, and protective plate. The sole is fixedly mounted at the bottom of the shoe upper, and the insole is movably mounted inside the shoe upper. A protective plate is movably mounted at the bottom of the insole. The anti-impact component is located at the front of the shoe upper, and includes a toe cap, a support plate, a steel plate, a damper, a buffer spring, a retaining plate, and a groove. The toe cap is fixedly mounted at the front of the shoe upper, and the support plate is movably mounted on top of the toe cap. A steel plate is mounted on top of the support plate. This safety shoe, through the inclusion of the anti-impact component, further improves the safety performance of the safety shoe, thereby enhancing its practicality. Furthermore, when no safety protection is needed, the anti-impact component can be disassembled for everyday wear, making the safety shoe more convenient to use and applicable to a wider range of situations.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: the toe area of ​​safety shoes is generally made of rigid material, and this rigidity is used to prevent heavy objects from pressing down and injuring the toes. However, the rigid material of the existing toe area is prone to deformation when subjected to heavy objects, and this deformation can easily cause the toes to get stuck inside the shoe. Utility Model Content

[0005] The purpose of this invention is to provide a safety shoe made of carbon fiber composite material to solve the problem in the above-mentioned background technology that the rigid material of the shoe toe is prone to deformation when subjected to heavy objects, and that the deformation of the shoe toe can easily cause the toes to get stuck inside the shoe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber composite safety shoe, comprising an upper and a sole, wherein the upper is fixed to the top of the sole by hot-melt bonding, and a protective component is embedded in the interlayer of the upper;

[0007] The protective components include a front protective sheet and side protective sheets. The front protective sheet covers the front end of the shoe, and the side protective sheets are symmetrically arranged on both sides of the foot. Both the front and side protective sheets have a hollow structure.

[0008] Preferably, the bottom of the front protective plate and the side protective plate are fixedly connected with a fixing ring, and the fixing ring is located inside the sole.

[0009] Preferably, the outer front end of the shoe is fixedly connected to a toe, and the bottom of the toe is fixedly connected to the top front end of the sole.

[0010] Preferably, an annular eyelet is fixedly connected to the rear side of the shoe upper, and the two ends of the annular eyelet are located at the top center of the shoe upper.

[0011] Preferably, both ends of the annular eyelet are provided with equidistant shoelace holes, and shoelaces are threaded through the shoelace holes.

[0012] Preferably, the top of the sole is provided with an insole, and the bottom of the sole is provided with anti-slip texture. The insole is located inside the front protective plate and the side protective plate, and the insole is located at the bottom of the upper.

[0013] Preferably, the top of the sole is provided with hexagonal ventilation holes, and the sides of the sole are provided with equidistant reserved holes, and the connection points of the front protective plate and the side protective plate with the fixing ring are located inside the reserved holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This carbon fiber composite safety shoe features a perforated carbon fiber front and side protective plates. These plates form a three-dimensional protective net through fixing rings and pre-drilled holes in the sole. The protective components adapt to deformation when the shoelaces are tightened. Combined with the double-layer cushioning structure of the upper, the impact force is transmitted through three levels: the toe, the front protective plate, the side protective plates, and the anti-slip treads on the sole. This disperses the impact force and prevents deformation from penetrating into the shoe by supporting the toe with the front protective plate.

[0016] The ventilation hole matrix and insole form an air circulation system, effectively reducing the accumulation of moisture on the feet. The circular eyelet plate achieves dynamic pressure distribution in the arch area through equidistant shoelace holes, maintaining a good fit to the foot within the range of shoelace tension.

[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: a carbon fiber composite safety shoe, including an upper 1 and a sole 2. The upper 1 is fixed to the top of the sole 2 by hot-melt bonding. A protective component is embedded in the interlayer of the upper 1. The protective component includes a front protective plate 3 and side protective plates 4. The front protective plate 3 covers the front end area of ​​the shoe, and the side protective plates 4 are symmetrically arranged on both sides of the foot. Both the front protective plate 3 and the side protective plates 4 have a hollow structure. A fixing ring 5 is fixedly connected to the bottom of the front protective plate 3 and the side protective plate 4, and the fixing ring 5 is located inside the sole 2. A toe cap 6 is fixedly connected to the outer front end of the upper 1, and the bottom of the toe cap 6 is fixedly connected to the front of the sole 2. The upper 1 has a ring-shaped eyelet 7 fixedly connected to the back side, with both ends of the ring-shaped eyelet 7 located at the top center of the upper 1; both ends of the ring-shaped eyelet 7 are provided with equidistant shoelace holes 8, and shoelaces are threaded through the shoelace holes 8; the top of the sole 2 is provided with an insole 9, and the bottom of the sole 2 is provided with anti-slip texture 10. The insole 9 is located inside the front protective plate 3 and the side protective plate 4, and the insole 9 is located at the bottom of the upper 1; the top of the sole 2 is provided with hexagonal ventilation holes 11, and the sides of the sole 2 are provided with equidistant reserved holes 12, and the connection points of the front protective plate 3 and the side protective plate 4 with the fixing ring 5 are located inside the reserved holes 12.

[0026] During the production of safety shoes, the sole 2 is produced by a molding device. At this time, a groove will be formed on the top of the sole 2. The protective components consisting of the front protective plate 3, the side protective plate 4, and the fixing ring 5 are then bonded to the groove on the top of the sole 2. At this time, the ventilation hole 11 is installed inside the groove on the top of the sole 2. The top of the fixing ring 5 is fixed through the ventilation hole 11, and the ventilation hole 11 will form a reserved hole 12 on the top of the sole 2. At this time, the front protective plate 3 and the side protective plate 4 will be fixed to the top of the sole 2.

[0027] The upper 1 has a composite structure. First, the inner layer of the upper 1 is installed on the outside of the front protective plate 3 and the side protective plate 4, completely covering the front protective plate 3 and the side protective plate 4. After the inner layer of the upper 1 is fixed, the outer layer of the upper 1 is fixed on the outside of the front protective plate 3 and the side protective plate 4. At this time, the front protective plate 3 and the side protective plate 4 will be located in the interlayer of the upper 1. At this time, the front protective plate 3 and the side protective plate 4 will respectively reinforce the front end and the sides of the upper 1. After the upper 1 is fixed, the toe 6 is fixed on the outside of the front end of the upper 1. At this time, the toe 6 will cover the top of the front protective plate 3, and the front protective plate 3 will support the bottom of the toe 6.

[0028] The upper 1 employs a double-layer composite structure to form a flexible protective layer. The forefoot protective plate 3 and the side protective plates 4 are anchored to the pre-drilled holes 12 inside the sole 2 via fixing rings 5, forming a three-dimensional protective skeleton. The forefoot protective plate 3 is U-shaped and covers the toe area, while the side protective plates 4 are symmetrically distributed on both sides of the arch. Both are made of perforated carbon fiber sheets, ensuring structural strength while retaining space for elastic deformation. The annular eyelet 7 and the shoelace holes 8 form a dynamic tightening system, allowing for adjustment of the fit between the upper 1 and the foot through shoelace tension.

[0029] Primary protection involves the toe cap 6 absorbing direct impact, with its internal forefoot protective plate 3 absorbing kinetic energy through the elastic deformation of carbon fiber material. Secondary protection uses the hollow structure of the side protective plates 4 to disperse lateral impact force, and their rigid connection with the fixing ring 5 transmits the impact to the sole 2. Tertiary protection relies on the buffer cavity formed by the double-layer structure of the upper 1, combined with the flexible support of the insole 9 to disperse foot stress. When a forward impact occurs, the carbon fiber mesh structure of the forefoot protective plate 3 can deform at an angle, converting the point impact into a surface load, while the hexagonal ventilation hole array 11 of the sole 2 further absorbs residual energy through structural deformation.
