Description

Technical Field

[0001] This utility model relates to the field of safety footwear technology, and more specifically, to an impact energy dispersion structure between the sole and steel toe cap of a safety shoe. Background Technology

[0002] In the field of safety footwear technology, steel toe caps, as core protective components, play a crucial role in protecting toes from external impacts such as falling objects and collisions, and are directly related to the foot safety of workers. The impact resistance of safety shoes is an important indicator for ensuring the safety of personnel in outdoor work, industrial production and other scenarios, and its protective effect is closely related to the reasonable distribution of impact force and the cushioning design.

[0003] A search revealed that Chinese patent CN217885215U discloses "an impact-resistant safety shoe, comprising a sole and an upper. The sole has a steel wire layer on its inner side and an elastic cushioning pad on top. The upper is a double-layered fiber cloth with a rigid metal plate on its inner side. The surface of the rigid metal plate has evenly spaced ventilation holes. A breathable capsule is located between the bottom of the rigid metal plate and the inner side of the upper. Air outlets are evenly spaced on the surface of the breathable capsule. The bottom left side of the breathable capsule is connected to the inner side of the elastic cushioning pad. Air holes are evenly spaced on the bottom surface of the breathable capsule. The use of the rigid metal plate and the elastic cushioning pad allows the upper to bend and compress the elastic cushioning pad during walking, thus accelerating the exchange of air between the foot and the outside air and improving breathability." However, the following drawbacks still exist: (1) In actual use, the safety shoe only achieves basic impact resistance and breathability through hard metal plate and elastic cushioning pad. It does not have a special structure to disperse the impact force between the sole and the steel toe cap. The impact force is easily concentrated on the contact surface between the steel toe cap and the sole, resulting in excessive local stress, which affects the impact protection effect and structural stability. (2) In actual use, the safety shoe lacks a targeted cushioning and protection design inside the steel toe cap, and the external impact-resistant structure cannot completely absorb the residual impact force. The impact force is easily transmitted directly to the toes, which not only reduces wearing comfort but also makes it difficult to provide precise protection for the toes. To address this, an impact energy dispersion structure between the sole and the steel toe cap of the safety shoe is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing impact-resistant safety shoes, which only rely on rigid metal plates and elastic cushioning pads to achieve basic impact resistance and breathability. These shoes lack a dedicated structure to disperse impact forces between the sole and the steel toe cap, leading to concentrated impact forces at the contact surface between the toe cap and sole, resulting in excessive localized stress and affecting impact protection and structural stability. Furthermore, the lack of targeted cushioning design within the steel toe cap means the external impact-resistant structure cannot fully absorb residual impact forces, allowing them to be directly transmitted to the toes. This not only reduces wearing comfort but also fails to provide precise protection for the toes. The invention provides an impact energy dispersion structure between the sole and the steel toe cap of a safety shoe to solve these problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: an impact energy dispersion structure between the sole and the steel toe cap of a safety shoe, comprising a sole body, wherein a dispersion component for dispersing the impact force between the sole body and the steel toe cap is provided on the top of the sole body, and a buffer component for further buffering the impact force on the toes is provided on the dispersion component. The dispersion component includes an elastic pad fixedly installed on the top of the sole body, a steel toe cap body disposed on the top of the elastic pad corresponding to the toe area, an upper body disposed on the remaining area of ​​the top of the elastic pad, an annular cushioning pad fixedly installed on the periphery of the elastic pad, the top of the annular cushioning pad being fixedly connected to the periphery of the steel toe cap body and the periphery of the bottom of the upper body, the bottom of the annular cushioning pad being fixedly connected to the top of the sole body, a plurality of cushioning holes being formed on the periphery of the annular cushioning pad, the interior of the cushioning holes being filled with elastic cushioning particles, and a silicone sealing gasket fixedly installed on the periphery of the annular cushioning pad, the silicone sealing gasket covering the plurality of cushioning holes.

[0006] As a preferred technical solution of this utility model, the buffer assembly includes a flexible inner lining layer bonded to the inner wall of the steel head body, and a plurality of independent airbag units are arranged inside the flexible inner lining layer, and the interior of the plurality of independent airbag units is filled with elastic foam particles.

[0007] As a preferred technical solution of this utility model, the top of the elastic pad is provided with a shock-absorbing insole. The shock-absorbing insole adopts a layered composite structure, with the bottom layer being a PU foam sole and the top layer being a breathable mesh fabric, and the two are bonded together and fixed by an environmentally friendly polyurethane adhesive.

[0008] As a preferred technical solution of this utility model, the top of the shock-absorbing insole is provided with massage particles, which are distributed corresponding to the forefoot and arch areas of the human foot, and the heel part of the shock-absorbing insole is integrally provided with a heel pad.

[0009] As a preferred technical solution of this utility model, a wear-resistant layer is fixedly installed on the bottom of the shoe sole body, and the wear-resistant layer is made of a blended modified material of nitrile rubber and polyurethane.

[0010] As a preferred technical solution of this utility model, the forefoot portion of the sole body and the annular cushioning pad is provided with an edge-wrapping anti-collision layer, and the material of the edge-wrapping anti-collision layer is a high-elasticity polyolefin elastomer.

[0011] As a preferred technical solution of this utility model, the surface of the edge-sealing anti-collision layer is provided with a plurality of rubber strips, and the plurality of rubber strips and the edge-sealing anti-collision layer are integrally formed by hot vulcanization.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By using the set dispersion components, and with the synergistic effect of elastic pads, ring-shaped buffer pads, elastic buffer particles in the buffer holes and silicone sealing pads, the impact force between the sole body and the steel toe cap body is efficiently dispersed. This component can evenly transmit external impact force on the contact surface, avoid local force concentration, significantly improve the basic impact resistance performance of safety shoes, extend the service life of the sole body and the steel toe cap body, provide an outer protective barrier for the feet, ensure the structural stability of safety shoes under complex working conditions, and meet the core protection requirements of safety shoes; 2. By utilizing a multi-layered cushioning structure consisting of a flexible inner lining, independent airbag units, and elastic foam particles, the design of the cushioning component addresses the issues of the dispersion component only dispersing impact force from the outside and the insufficient cushioning protection for the toes from within the steel toe cap. This component further absorbs residual impact force from within the steel toe cap, reducing the direct impact on the toes through both deformation and compression energy absorption. This improves wearing comfort and protection accuracy, filling the gap in protection provided by a single external dispersion structure, and making the impact protection of the safety shoe more comprehensive and better suited to the needs of foot protection.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0016] Example: Figures 1-5 As shown, this embodiment proposes an impact energy dispersion structure between the sole and the steel toe cap of a safety shoe, including a sole body 1, a dispersion component 2 for dispersing the impact force between the sole body 1 and the steel toe cap body 202 is provided on the top of the sole body 1, and a buffer component 3 for further buffering the impact force on the toes is provided on the dispersion component 2. like Figure 3 and Figure 4 As shown, the dispersion component 2 includes an elastic pad 201 fixedly installed on the top of the sole body 1. A steel toe cap 202 is provided on the top of the elastic pad 201 corresponding to the toe area. The remaining area on the top of the elastic pad 201 is provided with an upper 203. An annular cushioning pad 204 is fixedly installed on the periphery of the elastic pad 201. The top of the annular cushioning pad 204 is fixedly connected to the periphery of the steel toe cap 202 and the bottom periphery of the upper 203. The bottom of the annular cushioning pad 204 is fixedly connected to the top of the sole body 1. Several cushioning holes 205 are opened on the periphery of the annular cushioning pad 204. The interior of the cushioning holes 205 is filled with elastic cushioning particles 206. A silicone sealing gasket 207 is fixedly installed on the periphery of the 4. The silicone sealing gasket 207 covers several buffer holes 205. When in use, when an impact force is applied to the steel toe cap body 202 and the upper 203, the impact force is first transmitted to the annular buffer pad 204. The elastic buffer particles 206 in the buffer holes 205 on the periphery of the annular buffer pad 204 will deform and absorb part of the impact energy. At the same time, the elasticity of the annular buffer pad 204 itself will also disperse the impact force. The elastic pad 201 will also further buffer through its own elasticity, so that the impact force is effectively dispersed among the sole body 1, the elastic pad 201, and the annular buffer pad 204, avoiding the impact force from being concentrated on a certain part.

[0017] like Figure 4 As shown, the cushioning component 3 includes a flexible inner lining layer 301 bonded to the inner wall of the steel toe cap 202. The flexible inner lining layer 301 contains several independent airbag units 302, each filled with elastic foam particles 303. During use, when the toes are impacted, the impact force is transmitted to the flexible inner lining layer 301 on the inner wall of the steel toe cap 202. The several independent airbag units 302 inside the flexible inner lining layer 301 deform due to compression, and the elastic foam particles 303 inside are also compressed, thereby absorbing and cushioning the impact force. Simultaneously, the flexibility of the flexible inner lining layer 301 itself also protects the toes, further reducing the damage to the toes from the impact force. This disperses and cushions the impact force from within the steel toe cap 202, working in conjunction with the dispersion component 2's external dispersion of the impact force between the sole body 1 and the steel toe cap 202. This comprehensively enhances the impact resistance of the safety shoe, effectively solving the problem of insufficient protection from a single dispersion structure.

[0018] like Figure 3 As shown, the top of the elastic pad 201 is equipped with a shock-absorbing insole 4. The shock-absorbing insole 4 adopts a layered composite structure. The bottom layer is a PU foam sole, and the top layer is a breathable mesh fabric. The two are bonded together with an environmentally friendly polyurethane adhesive. When in use, when walking or standing, the bottom layer of the shock-absorbing insole 4, the PU foam sole, can buffer the reaction force of the ground through its own foaming structure. The top layer of breathable mesh fabric ensures the breathability of the foot. The layered structure of the environmentally friendly polyurethane adhesive makes the shock-absorbing insole 4 provide shock absorption and comfort for the foot, and help to play an overall role in dispersing impact energy.

[0019] like Figure 3 As shown, the top of the shock-absorbing insole 4 is equipped with massage particles 5, which are distributed in the forefoot and arch areas of the human foot. The heel pad 6 is integrally set in the heel area of ​​the shock-absorbing insole 4. When in use, the massage particles 5 of the shock-absorbing insole 4 massage the forefoot and arch to promote circulation, and the heel pad 6 cushions the impact of the heel and disperses the pressure. This design improves wearing comfort while helping the overall structure protect the foot and assists in the dispersion of impact energy.

[0020] like Figure 5 As shown, a wear-resistant layer 7 is fixedly installed on the bottom of the sole body 1. The wear-resistant layer 7 is made of a blend of nitrile rubber and polyurethane modified material. When in use, the wear-resistant layer 7 on the bottom of the sole body 1 is made of a blend of nitrile rubber and polyurethane modified material. This material has excellent wear resistance. During the walking process of the safety shoe, the wear-resistant layer 7 can effectively resist the friction of the ground, extend the service life of the sole body 1, ensure the durability of the safety shoe under various working conditions, and provide a durable foundation for the overall impact energy dispersion structure.

[0021] like Figure 1As shown, the forefoot area of ​​the sole body 1 and the annular cushioning pad 204 is provided with an edge-protecting anti-collision layer 8. The edge-protecting anti-collision layer 8 is made of high-elasticity polyolefin elastomer. When the forefoot area is impacted during use, the edge-protecting anti-collision layer 8 of the sole body 1 and the annular cushioning pad 204, made of high-elasticity polyolefin elastomer material, will undergo elastic deformation to absorb the impact force generated by the collision, thereby playing an anti-collision protection role for the forefoot area and preventing the steel toe cap body 202, toes and other parts from being injured by the collision.

[0022] like Figure 1 As shown, the surface of the edge-protecting anti-collision layer 8 is provided with several rubber strips 9. The rubber strips 9 are integrally formed with the edge-protecting anti-collision layer 8 through hot vulcanization. In use, the rubber strips 9 on the surface of the edge-protecting anti-collision layer 8 are integrally formed with the edge-protecting anti-collision layer 8 through hot vulcanization. When the front part of the foot is subjected to friction or slight collision, the rubber strips 9 can increase the friction and impact resistance of the contact surface, further improving the protective performance and wear resistance of the edge-protecting anti-collision layer 8.

[0023] Working Principle: This utility model provides an impact energy dispersion structure between the sole and steel toe cap of a safety shoe. The specific usage steps are as follows: When an impact force acts on the steel toe cap body 202 and the upper 203, the impact force is first transmitted to the annular buffer pad 204. The elastic buffer particles 206 within the buffer holes 205 around the annular buffer pad 204 deform, absorbing some of the impact energy. Simultaneously, the elasticity of the annular buffer pad 204 itself disperses the impact force. The elastic pad 201 further buffers the impact through its own elasticity, effectively dispersing the impact force among the sole body 1, the elastic pad 201, and the annular buffer pad 204, preventing the impact force from concentrating on a single area (e.g., the toe cap). Figure 3 and Figure 4 As shown), when the toes are impacted, the impact force is transmitted to the flexible inner lining layer 301 on the inner wall of the steel toe cap 202. Several independent airbag units 302 inside the flexible inner lining layer 301 deform due to compression, and the internal elastic foam particles 303 are also compressed, thereby absorbing and buffering the impact force. Simultaneously, the flexibility of the flexible inner lining layer 301 itself also protects the toes, further reducing the damage to the toes from the impact force. This disperses and buffers the impact force from within the steel toe cap 202, working in conjunction with the dispersion component 2's external dispersion of the impact force between the sole body 1 and the steel toe cap 202. This comprehensively improves the impact resistance of the safety shoe, effectively solving the problem of insufficient protection from a single dispersion structure (e.g., Figure 4 (As shown).

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
