Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe sole technology, and in particular to an elastic cushioning shoe sole. Background Technology
[0002] The sole is a crucial component of a shoe, located at the bottom and in direct contact with the ground. Like the foundation of a house, it plays a vital supporting role. Functionally, the primary function of the sole is to provide stable support, ensuring our feet maintain balance when standing, walking, or exercising. It evenly distributes body weight, preventing excessive localized pressure and ensuring comfort for our feet.
[0003] The sole of a shoe plays a crucial role in cushioning and shock absorption. During walking or running, the sole absorbs the impact force from the ground. When the foot lands, the sole converts the impact force into other forms of energy through its own elastic deformation or internal cushioning materials, reducing damage to the joints, bones, and muscles of the foot. Furthermore, the material and design of the sole determine the shoe's anti-slip performance. Special patterns and materials increase friction with the ground, making it less likely for us to slip when walking on wet or uneven surfaces.
[0004] However, some existing shoe soles lack sufficient elastic cushioning, causing not only noticeable soreness and discomfort in the feet within a short period, but also potential damage to the joints, bones, and muscles of the legs over time, thus affecting overall health and normal mobility. Furthermore, it also impacts the overall performance and lifespan of the shoe. Therefore, this paper proposes an elastic cushioning sole to address these shortcomings. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an elastic cushioning sole, which aims to improve the problem of poor elastic cushioning effect in some existing soles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An elastic cushioning sole includes a base layer, an isolation layer fixedly connected to the top of the base layer, a breathable and antibacterial component disposed on the top of the isolation layer, an elastic cushioning mechanism disposed at the bottom of the base layer, and an insole fixedly connected to the bottom of the elastic cushioning mechanism.
[0008] The elastic buffer mechanism includes a first reinforcing layer and multiple sliding rods. The top of the first reinforcing layer is fixedly connected to the bottom of the base layer. A buffer layer is fixedly connected to the bottom of the first reinforcing layer. A second reinforcing layer is fixedly connected to the bottom of the buffer layer. Multiple elastic arc-shaped plates are fixedly connected inside the buffer layer. A connecting plate is movably connected inside each of the multiple elastic arc-shaped plates. Springs are sleeved on the outside of each of the multiple sliding rods. Limiting plates are fixedly connected to the upper and lower sides of each of the multiple sliding rods.
[0009] As a further description of the above technical solution:
[0010] The breathable and antibacterial mechanism includes a breathable layer, the bottom of which is fixedly connected to the top of the isolation layer, an antibacterial layer fixedly connected to the top of the breathable layer, and a heel pad fixedly connected to the top left side of the isolation layer.
[0011] As a further description of the above technical solution:
[0012] The sliding rod is externally slidably connected to the inside of the connecting plate, and the top of the limiting plate is in contact with the bottom of the elastic arc plate;
[0013] As a further description of the above technical solution:
[0014] One end of the spring is fixedly connected to the bottom of the connecting plate near the side of the insulating layer, and the other end of the spring is fixedly connected to the top of the connecting plate near the side of the shoe sole.
[0015] As a further description of the above technical solution:

[0020] The bottom of the second reinforcement layer is fixedly connected to the top of the shoe sole, and the cushioning layer is made of high-elastic sponge material.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the multiple elastic arc-shaped plates inside the buffer layer are ingeniously designed. When subjected to force, they can generate elastic deformation, converting the vertical impact force into arc-shaped elastic potential energy, which is then slowly released, further enhancing the buffering effect. The spring is compressed or stretched as the sliding rod slides, thereby storing elastic potential energy. Under different force conditions, it can provide appropriate elasticity to effectively buffer the impact force. The EVA material of the base layer also has a certain degree of elasticity, which can help disperse foot pressure. In addition, the top isolation layer plays an isolation and auxiliary buffering role, achieving excellent elastic buffering of the sole. This allows the wearer to feel a comfortable walking experience under different walking postures and various ground conditions, effectively reducing foot fatigue and the risk of injury.
[0023] 2. In this invention, the breathable layer is made of bamboo fiber. Bamboo fiber itself has abundant micropores, allowing air to circulate freely. During daily wear, moisture and heat generated inside the shoe can be easily expelled through the breathable layer, keeping feet dry and comfortable. The antibacterial layer is made of nano-silver ion antibacterial material. Nano-silver ions can combine with proteins on the surface of bacteria, thereby destroying the bacterial cell membrane and cell wall, inhibiting bacterial growth and reproduction, and further enhancing the overall antibacterial function of the sole. Through the synergistic effect of the breathable and antibacterial layers, the sole can effectively prevent foot health problems caused by bacterial growth, improving wearing comfort and hygiene.

[0030] 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.
[0031] Reference Figures 1 to 3 This utility model provides an embodiment of an elastic cushioning sole, comprising a base layer 1 made of EVA material. The base layer 1 serves as the basic structural component of the sole, playing a crucial supporting role. The EVA material used possesses good flexibility, lightweight properties, and a certain degree of elasticity, enabling it to adapt to different walking postures and ground conditions, effectively dispersing foot pressure and providing a more comfortable walking experience for the wearer. An isolation layer 10 is fixedly connected to the top of the base layer 1. The isolation layer 10 serves to isolate and cushion, preventing direct friction between the base layer 1 and the upper breathable and antibacterial components, reducing wear between components, and also assisting in cushioning pressure from above to a certain extent, making the cushioning performance of the sole more uniform and stable. The top of the isolation layer 10 is provided with a breathable and antibacterial component, and the bottom of the base layer 1 is provided with an elastic cushioning mechanism. The bottom of the elastic cushioning mechanism is fixedly connected to the sole 14, which is made of polyurethane foam. The elastic cushioning mechanism includes a reinforcing layer 2 and multiple sliding rods 7. The top of the reinforcing layer 2 is fixedly connected to the bottom of the base layer 1. The function of the reinforcing layer 2 is to enhance the stability and strength of the sole structure, withstand the pressure from above, and evenly transfer it to the cushioning layer 3 below, preventing the sole from being excessively deformed or damaged during the stress process.
[0032] A cushioning layer 3 is fixedly connected to the bottom of reinforcement layer 2. The cushioning layer 3 is made of high-elastic sponge. When the sole is subjected to external force, the high-elastic sponge can quickly deform, absorbing and dispersing the impact force, effectively reducing the vibration experienced by the foot. The elastic properties of the high-elastic sponge allow it to quickly return to its original shape after being subjected to force, ready to receive the next impact, thus providing continuous cushioning protection for the wearer. A second reinforcement layer 4 is fixedly connected to the bottom of cushioning layer 3. The bottom of reinforcement layer 4 is fixedly connected to the top of sole 14. Multiple elastic arc-shaped plates 5 are fixedly connected inside cushioning layer 3. The elastic arc-shaped plates 5 can generate elastic deformation when subjected to force, converting the vertical impact force into arc-shaped elastic potential energy, and then slowly releasing it, thus achieving a more efficient cushioning effect. Connecting plates 6 are movably connected inside each of the multiple elastic arc-shaped plates 5. The external sliding rod 7 is slidably connected to the inside of the connecting plate 6. The connecting plate 6 serves as a connection and guide, allowing the sliding rod 7 to slide smoothly inside, thereby realizing the elastic deformation and cushioning function of the sole when subjected to force. Multiple sliding rods 7 are each fitted with a spring 8. One end of the spring 8 is fixedly connected to the bottom of the connecting plate 6 near the insulating layer 10, and the other end of the spring 8 is fixedly connected to the top of the connecting plate 6 near the sole 14. When the sole is subjected to force, causing the sliding rod 7 to slide, the spring 8 is compressed or stretched, thereby storing elastic potential energy to ensure that appropriate elasticity is provided under different force conditions, effectively cushioning the impact force on the foot and providing the wearer with a comfortable walking experience. Limiting discs 9 are fixedly connected to the upper and lower sides of the multiple sliding rods 7, and the top of the limiting discs 9 contacts the bottom of the elastic arc plate 5.
[0033] Reference Figures 2 to 4 The breathable and antibacterial mechanism includes a breathable layer 11 made of bamboo fiber. This bamboo fiber allows for free airflow, effectively expelling moisture and heat from the shoe, keeping feet dry and comfortable. Bamboo fiber also possesses antibacterial properties, inhibiting bacterial growth and creating a relatively clean environment for the feet, reducing odor and improving comfort and hygiene. The bottom of the breathable layer 11 is fixedly connected to the top of the insulating layer 10. An antibacterial layer 12, made of nano-silver ion antibacterial material, is fixedly connected to the top of the breathable layer 11. This further enhances the antibacterial function of the sole. Nano-silver ions can bind to proteins on the surface of bacteria, destroying the bacterial cell membrane and cell wall, thereby inhibiting bacterial growth and reproduction. A heel pad 13 is fixedly connected to the top left side of the isolation layer 10. The heel pad 13 is designed to provide additional cushioning and support for the heel during walking, thereby reducing the impact of the heel landing and relieving foot fatigue.
[0034] Working principle: When the wearer walks, the sole of the shoe contacts the ground and is subjected to external force. The base layer 1, made of EVA material, provides basic support, while the top isolation layer 10 prevents friction between components and assists in cushioning. In the elastic cushioning mechanism at the bottom, the reinforcing layer 2 enhances structural stability, the high-elasticity sponge material of the cushioning layer 3 quickly deforms to absorb and disperse the impact force, the internal elastic arc plate 5 converts the vertical impact force into arc-shaped elastic potential energy for efficient cushioning, the sliding rod 7 slides within the connecting plate 6, and the spring 8 fitted on it is compressed or stretched to store elastic potential energy to provide elastic cushioning, and the limiting plate 9 limits the stroke of the sliding rod 7 and protects related components. Meanwhile, in the breathable and antibacterial mechanism above the isolation layer 10, the bamboo fiber material of the breathable layer 11 expels moisture and heat and inhibits bacterial growth, the nano silver ion antibacterial material of the antibacterial layer 12 further inhibits bacteria, the heel pad 13 provides extra cushioning support for the heel area, and the polyurethane foam material of the sole 14 provides wear resistance, slip resistance and certain cushioning performance. The various structures work together to effectively reduce the vibration and impact on the feet, bringing the wearer a comfortable, healthy and safe walking experience, adapting to different walking postures and ground conditions, and maintaining stable and reliable sole cushioning performance.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
