Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing, and in particular to a lightweight and breathable shoe sole. Background Technology

[0002] With the ever-expanding uses of footwear, the shock absorption performance of shoe soles is becoming increasingly important. However, traditional shoe soles have significant shortcomings in shock absorption, seriously affecting wearing experience and athletic health. On the one hand, the shock absorption structure of traditional shoe soles is simple. Common single-material soles rely solely on limited elasticity for passive cushioning when facing impacts, failing to intelligently adapt to the varying impact forces generated by different sports, resulting in poor shock absorption. On the other hand, traditional shoe soles lack targeted shock absorption for different points of impact. During walking or exercise, the main impact points such as the forefoot and heel bear a large amount of impact, and traditional shoe soles struggle to accurately distribute the pressure in these areas, easily causing localized fatigue and injury. Utility Model Content

[0003] The main purpose of this invention is to propose a lightweight and breathable shoe sole, which aims to solve the problems of traditional shoe soles having simple shock absorption structures, relying on limited elasticity for passive cushioning, being unable to adapt to varying impact forces, lacking targeted shock absorption for major stress points such as the forefoot and heel, and easily causing local fatigue and injury.

[0004] To address the aforementioned problems, this utility model proposes a lightweight and breathable shoe sole, comprising a rubber sole and a sole edging disposed on the outer side of the rubber sole edge. The rubber sole and the sole edging are integrally formed by molding, and the outer wall of the rubber sole and the sole edging edge are flush. A shock-absorbing device is provided at the top of the rubber sole, and a breathable support pad is provided at the top of the shock-absorbing device. Both the shock-absorbing device and the breathable support pad are located inside the sole edging.

[0005] In one embodiment, the motion shock absorption device includes a soft rubber top plate, a soft rubber bottom plate, and a soft rubber edge seal. The soft rubber top plate and the soft rubber bottom plate are arranged parallel to each other vertically. The soft rubber bottom plate is attached to the top outer wall of the rubber shoe sole. A soft rubber edge seal is connected between the edges of the soft rubber top plate and the soft rubber bottom plate. The soft rubber edge seal is fixedly connected to the soft rubber top plate and the soft rubber bottom plate by adhesive and sealant.

[0006] In one embodiment, the soft rubber seal is flush with the outer wall of the soft rubber top sheet and the soft rubber bottom sheet at their edges, the area between the soft rubber seal and the soft rubber top sheet and the soft rubber bottom sheet is in a sealed state, and the area between the soft rubber seal and the soft rubber top sheet and the soft rubber bottom sheet is filled with inert gas.

[0007] In one embodiment, the motion damping device further includes highly elastic support cylinders, and multiple highly elastic support cylinders are equidistantly connected between the outer wall of the bottom end of the soft rubber top sheet and the outer wall of the top end of the soft rubber bottom sheet, and the multiple highly elastic support cylinders are all made of highly elastic soft silicone.

[0008] In one embodiment, the elastic coefficient of the high-elasticity support cylinder is greater than that of the soft rubber top sheet and the soft rubber bottom sheet, the elastic coefficient of the soft rubber top sheet and the soft rubber bottom sheet is greater than that of the breathable support pad of the sole, and the elastic coefficient of the breathable support pad of the sole is greater than that of the rubber sole.

[0009] In one embodiment, the breathable support pad of the sole is densely covered with breathable holes, and the breathable holes are arranged vertically inside the breathable support pad of the sole, and the edge of the breathable support pad of the sole is attached to the inner wall of the sole edging.

[0010] In one embodiment, the outer wall of the bottom end of the rubber shoe sole is densely covered with wear-resistant and anti-slip sole plates, which are fixedly connected to the rubber shoe sole by neoprene rubber adhesive.

[0011] In one embodiment, the rubber sole has upwardly recessed shock-absorbing grooves on both the front and rear sides at the center of the bottom end, and multiple wear-resistant and anti-slip sole plates surround the outside of the shock-absorbing grooves. The two shock-absorbing grooves are respectively located on the lower center of the rubber sole at the heel position and the lower center of the sole at the forefoot position.

[0012] In one embodiment, a rear impact protection strip is attached to the outer wall of the rear end of the sole edging, and a front impact protection strip is attached to the outer wall of the front end of the sole edging, and the thickness of both the rear impact protection strip and the front impact protection strip is greater than the thickness of the sole edging.

[0013] In one embodiment, each edge of the rear impact protection strip and the front impact protection strip is beveled, both of the rear impact protection strip and the front impact protection strip are made of rubber, and the hardness of both the rear impact protection strip and the front impact protection strip is greater than the hardness of the shoe sole edge.

[0014] Beneficial Effects: The technical solution of this utility model adds a novel sports shock absorption device between the rubber sole and the breathable support pad of the sole. The sports shock absorption device adopts a sealed structure composed of a soft rubber top plate, a bottom plate, and an edge seal, and is filled with inert gas. It can effectively buffer the impact force generated during walking or exercise, provide stable support for the feet, and reduce the adverse effects of vibration on the feet. Multiple high-elasticity support cylinders are made of high-elasticity soft silicone, and the elasticity coefficient is greater than that of the soft rubber top plate and bottom plate, which can further enhance the shock absorption performance of the device and play a good cushioning role under different exercise intensities. In addition, the elasticity coefficients of each component are set in a gradient, which, together with the breathable support pad of the sole, can more accurately disperse and absorb pressure from different directions and degrees, optimizing the overall shock absorption experience. This not only improves the comfort of the wearer, but also reduces the risk of sports injuries, providing reliable shock absorption protection for users during walking and exercise.

[0028] This utility model provides, for example Figure 1-6 The lightweight and breathable shoe sole shown includes a rubber sole 2 and a sole edging 3 located on the outer edge of the rubber sole 2. The rubber sole 2 and the sole edging 3 are integrally molded. This manufacturing process not only ensures a tight connection between the two, reducing safety hazards caused by the separation of sole components, but also makes the overall structure of the sole more stable. Furthermore, the outer walls of the edges of the rubber sole 2 and the sole edging 3 are flush. This smooth transition design enhances the overall aesthetics of the sole and avoids problems such as wear or scratches on clothing that may be caused by uneven edges. A sports shock absorption device 4 is provided at the top of the rubber sole 2, and a breathable support pad 5 is provided at the top of the sports shock absorption device 4. Both the sports shock absorption device 4 and the breathable support pad 5 are located at... Inside the sole edging 3, the breathable support pad 5 is densely covered with ventilation holes 6, which are vertically arranged inside the breathable support pad 5. The edge of the breathable support pad 5 is attached to the inner wall of the sole edging 3. The vertically arranged ventilation holes 6 can form a smooth air circulation channel. When the foot comes into contact with the sole and pressure changes, air can freely enter and exit through the ventilation holes 6, effectively expelling moisture and heat generated by the foot from the shoe, while allowing fresh air to enter the shoe, keeping the feet dry and comfortable. In addition, the attachment of the edge of the breathable support pad 5 to the inner wall of the sole edging 3 ensures the stability of the breathable support pad in the sole structure and helps prevent external dust and debris from entering the sole through the ventilation holes 6 and affecting the breathability.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the outer wall of the bottom end of the rubber sole 2 is densely covered with wear-resistant and anti-slip sole plates 7. The wear-resistant and anti-slip sole plates 7 are fixedly connected to the rubber sole 2 by neoprene rubber adhesive. The material and distribution design of the wear-resistant and anti-slip sole plates 7 are designed to increase the friction between the sole and the ground, thereby enhancing the anti-slip performance of the sole, reducing the risk of slipping, and ensuring the safety of the wearer during walking or exercise. At the same time, the wear-resistant properties can effectively resist the friction wear between the sole and the ground, extend the service life of the sole, reduce the damage to the sole caused by frequent friction, reduce the frequency of replacing soles or shoes, and improve the economic efficiency of the product. The center of the bottom end of the rubber sole 2 is provided with upwardly recessed shock-absorbing grooves 9 on both the front and back sides, and multiple wear-resistant and anti-slip sole plates 7 surround the outer side of the shock-absorbing grooves 9. The two cushioning grooves 9 are located on the lower center of the heel and the lower center of the forefoot of the rubber sole 2, respectively. The heel and the center of the forefoot are the main stress points of the human body during walking and exercise, and are easily subjected to greater impact. The design of the cushioning grooves 9 can deform under pressure, and reduce the pressure on the foot by absorbing and dispersing the impact force, thereby providing better cushioning protection for the foot and reducing the risk of fatigue and injury caused by prolonged walking or exercise. Multiple wear-resistant and anti-slip outsole pieces 7 surround the outer side of the cushioning grooves 9, which not only further enhances the wear resistance of the sole edge, but also helps the cushioning grooves 9 to disperse pressure to a certain extent, making the cushioning effect of the entire sole more uniform and effective.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rear impact protection strip 1 is attached to the outer wall of the rear end of the sole edging 3, and a front impact protection strip 8 is attached to the outer wall of the front end of the sole edging 3. The thickness of both the rear impact protection strip 1 and the front impact protection strip 8 is greater than the thickness of the sole edging 3. Each edge of both the rear impact protection strip 1 and the front impact protection strip 8 is beveled. Both the rear impact protection strip 1 and the front impact protection strip 8 are made of rubber, and their hardness is greater than that of the sole edging 3. This design is primarily to account for the fact that in daily life, the front and rear ends of the sole are easily subjected to collisions and impacts. When the sole is subjected to impacts from the front or rear... Upon impact, the thicker and harder rear impact protection strip 1 and front impact protection strip 8 can withstand the impact force first. Through their own deformation and cushioning, they disperse and absorb the impact force, thereby reducing damage to the sole edging 3 and the entire sole structure, extending the service life of the sole, and providing additional safety protection for the wearer. In addition, each edge of the rear impact protection strip 1 and the front impact protection strip 8 is beveled. This beveled design can not only prevent sharp edges from scratching the human body or surrounding objects, but also guide the direction of the impact force to a certain extent, further enhancing the cushioning and protective effect of the protection strip.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, the motion shock absorption device 4 includes a soft rubber top plate 10, a soft rubber bottom plate 11, and a soft rubber edge band 12. The soft rubber top plate 10 and the soft rubber bottom plate 11 are arranged vertically parallel to each other. The soft rubber bottom plate 11 is attached to the top outer wall of the rubber sole 2. The soft rubber edge band 12 connects the edges of the soft rubber top plate 10 and the soft rubber bottom plate 11. The soft rubber edge band 12 is fixedly connected to the soft rubber top plate 10 and the soft rubber bottom plate 11 by adhesive and sealant. The vertical parallel arrangement of the soft rubber top plate 10 and the soft rubber bottom plate 11 provides a stable force-bearing platform, ensuring that the device can withstand pressure. At the same time, the various parts of the device can evenly distribute and transmit force. The soft rubber bottom plate 11 is attached to the top outer wall of the rubber shoe sole 2, providing a stable support base for the entire sports shock absorption device 4, so that it is tightly combined with the rubber shoe sole 2 and works together. The soft rubber top plate 10 and the soft rubber bottom plate 11 are connected at the edges by soft rubber sealing edge 12. The soft rubber sealing edge 12 is firmly fixed to the soft rubber top plate 10 and the soft rubber bottom plate 11 with adhesive and sealant. This connection method not only ensures the stability of the structure, but also effectively prevents external moisture, dust and other impurities from entering the device and affecting its performance.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, the outer walls of the soft rubber edge seal 12 are flush with the edges of the soft rubber top plate 10 and the soft rubber bottom plate 11. The area between the soft rubber edge seal 12 and the soft rubber top plate 10 and the soft rubber bottom plate 11 is sealed, and the area between the soft rubber edge seal 12 and the soft rubber top plate 10 and the soft rubber bottom plate 11 is filled with inert gas. The flush design not only makes the overall appearance of the sports shock absorption device 4 smoother, but also helps it fit better with other components when installed inside the shoe sole. The area between the soft rubber edge seal 12 and the soft rubber top sheet 10 and soft rubber bottom sheet 11 is sealed and filled with inert gas, specifically nitrogen. Nitrogen is stable and does not readily react chemically with the soft rubber material, ensuring the long-term stability of the internal environment of the device. When subjected to external impact, the inert gas in the sealed space acts as a buffer, like an elastic air cushion, absorbing and dispersing the impact force through gas compression and expansion, reducing the pressure directly on the soft rubber top sheet 10 and bottom sheet, thus providing a softer and more comfortable support experience for the feet.

[0033] like Figure 1 , Figure 5 and Figure 6As shown, the motion damping device 4 also includes highly elastic support cylinders 13. Multiple highly elastic support cylinders 13 are equidistantly connected between the bottom outer wall of the soft rubber top plate 10 and the top outer wall of the soft rubber bottom plate 11. The multiple highly elastic support cylinders 13 are all made of highly elastic soft silicone. The highly elastic soft silicone material gives the support cylinders good elasticity and flexibility, enabling them to undergo large deformation under pressure without being easily damaged. The multiple support cylinders are equidistantly distributed, which can evenly distribute the pressure from above and avoid excessive local pressure that could damage the soft rubber top plate 10 or the bottom plate. At the same time, the elastic coefficient of the highly elastic support cylinders 13 is greater than that of the soft rubber top plate 10 and the soft rubber bottom plate 11. This difference in elastic coefficient is designed to achieve a more precise damping effect. When subjected to a large impact force, the highly elastic support cylinders 13 first play the main buffering role, absorbing most of the energy through their own large elastic deformation, and then transferring the remaining force to the soft rubber top plate 10 and the bottom plate for further dispersion and buffering, forming a multi-layered damping system.

[0034] like Figure 1 , Figure 5 and Figure 6 As shown, the elastic coefficient of the high-elasticity support cylinder 13 is greater than that of the soft rubber top plate 10 and the soft rubber bottom plate 11. The elastic coefficients of the soft rubber top plate 10 and the soft rubber bottom plate 11 are greater than that of the breathable support pad 5 of the sole. The elastic coefficient of the breathable support pad 5 of the sole is greater than that of the rubber sole 2. There is a gradient of elastic coefficients between the entire shock-absorbing device 4 and other components of the sole. Specifically, the elastic coefficient of the high-elasticity support cylinder 13 is greater than that of the soft rubber top plate 10 and the soft rubber bottom plate 11, the soft rubber top plate 10 and the soft rubber bottom plate 11 are greater than that of the breathable support pad 5 of the sole, and the breathable support pad 5 of the sole is greater than that of the rubber sole 2. This gradient design of elastic coefficients is intended to achieve energy... Through the gradual attenuation and dispersion of energy, when the foot applies pressure to the sole, the energy is first transferred to the breathable support pad 5 of the sole. Due to its relatively small elastic coefficient, it will first buffer and disperse the energy to a certain extent. Then, the energy is transferred to the motion shock absorption device 4. The soft rubber top plate 10, the bottom plate, and the high elastic support cylinder 13 absorb and disperse the energy in turn according to their different elastic coefficients. Finally, the smaller force after being buffered layer by layer is transferred to the rubber sole 2. Through this gradient design of elastic coefficient, the impact force felt by the foot can be effectively reduced, providing a more comfortable and stable wearing experience. At the same time, it also reduces the damage to various parts of the sole caused by excessive impact force and extends the service life of the entire sole structure.
