Description

Technical Field

[0001] This utility model relates to the field of badminton shoe technology, specifically to a novel shoe sole structure. Background Technology

[0002] Badminton shoes are professional footwear specifically designed for badminton, aiming to provide excellent grip, stability, cushioning, and flexibility to meet the needs of athletes during high-intensity activities such as rapid starts, stops, changes of direction, and jumps. Badminton shoes typically use lightweight, breathable upper materials, such as mesh or synthetic leather, to reduce weight, enhance breathability, and keep feet dry. The outsoles use abrasion-resistant rubber or special composite materials with strong anti-slip properties to adapt to different court surfaces, including wooden and synthetic floors. The midsole usually uses EVA, TPU, or other highly elastic materials to provide cushioning and energy return to the foot, reducing impact on the knees and ankles.

[0003] Current badminton shoe midsoles mostly use EVA or PU materials. While these materials offer some cushioning and rebound performance, they struggle to balance lightweight design, stable support, and durability. EVA provides good cushioning but lacks sufficient rebound, while PU offers good rebound but is relatively heavy. A single material cannot provide optimal mechanical response across different athletic stages. Furthermore, traditional midsoles lack dynamic adaptability and cannot be optimized for different stress areas such as forefoot push-off, heel landing, and lateral gliding, thus affecting athletic performance. In addition, lightweight designs often sacrifice cushioning or support, and the materials are prone to deformation after long-term use, leading to a decrease in cushioning capacity and affecting lifespan. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a novel shoe sole structure to solve the technical problem that traditional midsoles lack dynamic adaptability and cannot optimize for different force-bearing areas such as forefoot push-off, heel landing, and lateral gliding, thus affecting athletic performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel shoe sole, comprising a support layer, wherein the support layer includes an impact absorption zone and an energy feedback zone, the impact absorption zone is located on the front side of the top of the support layer, the energy feedback zone is located on the rear side of the top of the support layer, a shock-absorbing layer is provided at the top of the support layer, and a contact layer is fixedly connected to the top of the shock-absorbing layer.

[0006] By adopting the above technical solution and employing a dual-layer, dual-core structure design, the insole achieves a balance of high cushioning, high rebound, and stable support without adding extra weight. The shock-absorbing columns in the shock-absorbing layer deform under stress, absorbing and evenly dispersing impact energy, effectively reducing the impact on the foot, improving cushioning, and reducing the impact burden on the foot and knee during exercise. Simultaneously, the cushioning plate further optimizes the force distribution, preventing excessive localized stress, helping to reduce foot fatigue, and improving the overall comfort and durability of the sole. The support layer contains impact absorption and energy feedback zones. The impact absorption zone effectively disperses the impact force upon landing, preventing excessive deformation of the sole and enhancing stability during exercise. The energy feedback zone stores some impact energy and releases it upon push-off, providing additional rebound force, improving the athlete's starting speed and jumping ability, and optimizing athletic performance. Furthermore, the interlocking design of the impact absorption zone, energy feedback zone, shock-absorbing columns, and cushioning plate effectively prevents misalignment between the insole and sole during vigorous exercise, improving the overall structural stability and durability.

[0007] Furthermore, the damping layer includes damping columns and buffer sheets. The damping columns are fixed to the rear side of the bottom end of the damping layer and are attached to the impact absorption zone.

[0008] By adopting the above technical solution, the shock-absorbing columns in the shock-absorbing layer deform under stress, which can absorb and evenly disperse impact energy, effectively reducing the impact on the feet.

[0009] Furthermore, the buffer sheet is fixed to the front side of the bottom end of the shock-absorbing layer, and the buffer sheet is attached to the energy feedback area.

[0010] By adopting the above technical solution, some impact energy can be stored in the energy feedback zone and released when pushing off the ground, providing additional rebound force and improving the athlete's starting speed and jumping ability.

[0011] Furthermore, the support layer is configured as a semi-enclosed type and is made of high-density EVA material.

[0012] By adopting the above technical solution, the semi-enclosed design achieves a more comfortable effect for the soles of the feet.

[0013] Furthermore, the contact layer and the damping layer are fixed together by an adhesive, and the damping layer is made of low-density EVA material.

[0014] By adopting the above technical solution, the combination of two layers and two shapes better balances comprehensive performance, achieving triple optimization of support, shock absorption, and balance.

[0015] Furthermore, the contact layer includes anti-slip textures, which are formed on the surface of the top side of the contact layer.

[0016] By adopting the above technical solution, the anti-slip texture of the contact layer can effectively enhance the friction between the foot and the insole, prevent the foot from slipping during exercise, improve the fit, and make wearing more stable and comfortable.

[0017] In summary, this utility model has the following beneficial effects: Through its double-layer, double-core structure design, the insole achieves a balance of high cushioning, high rebound, and stable support without adding extra weight. The shock-absorbing columns in the shock-absorbing layer deform under stress, absorbing and evenly dispersing impact energy, effectively reducing the impact on the foot, improving cushioning, and reducing the impact burden on the foot and knee during exercise. Simultaneously, the buffer sheet further optimizes the force distribution, preventing excessive localized stress, helping to reduce foot fatigue, and improving the overall comfort and durability of the sole. The support layer contains an impact absorption zone and an energy feedback zone. The impact absorption zone effectively disperses the impact force upon landing, preventing excessive deformation of the sole and enhancing stability during exercise. The energy feedback zone stores some impact energy, releasing it upon push-off to provide additional rebound force, improving the athlete's starting speed and jumping ability, and optimizing athletic performance. Furthermore, the interlocking design of the impact absorption zone, energy feedback zone, shock-absorbing columns, and buffer sheet effectively prevents misalignment between the insole and sole during vigorous exercise, improving the overall structural stability and durability.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] A novel type of shoe sole, such as Figure 1-3As shown, it includes a support layer 1, which includes an impact absorption area 101 and an energy feedback area 102. The impact absorption area 101 is located on the front side of the top of the support layer 1, and the energy feedback area 102 is located on the rear side of the top of the support layer 1. A shock-absorbing layer 3 is provided at the top of the support layer 1, and a contact layer 2 is fixedly connected to the top of the shock-absorbing layer 3. Specifically, during use, the foot first contacts the contact layer 2. The top of the contact layer 2 is provided with anti-slip texture 201, which can enhance the friction between the foot and the insole, prevent the foot from slipping during exercise, and improve the fit and comfort. At the same time, the pressure applied by the foot is evenly transmitted to the shock-absorbing layer 3 through the contact layer 2. The shock-absorbing column 301 deforms when subjected to force, absorbing and dispersing the impact energy, effectively reducing the impact on the foot and improving the cushioning effect. Meanwhile, the cushioning plate 302 further optimizes the force distribution, reducing foot fatigue during high-intensity exercise and improving the overall comfort and durability of the sole.

[0023] Please see Figure 1-3 The shock-absorbing layer 3 includes a shock-absorbing column 301 and a buffer plate 302. The shock-absorbing column 301 is fixed to the rear side of the bottom end of the shock-absorbing layer 3 and is attached to the impact absorption area 101. The buffer plate 302 is fixed to the front side of the bottom end of the shock-absorbing layer 3 and is attached to the energy feedback area 102. Specifically, when the impact force continues to be transmitted downward, the support layer 1 plays a role. The support layer 1 has an impact absorption area 101 and an energy feedback area 102 inside. The impact absorption area 101 can effectively disperse the impact force when landing, prevent excessive deformation of the sole, and enhance stability. The energy feedback area 102 stores some impact energy and releases it when pushing off the ground, providing additional rebound force and improving the athlete's starting speed and jumping ability. Furthermore, the engagement of the impact absorption zone 101 and energy feedback zone 102 with the shock absorption column 301 and buffer plate 302 further enhances the synergistic effect of each functional area, preventing misalignment between the insole and the sole during vigorous exercise, thereby enhancing overall stability and durability.

[0024] Please see Figure 1 and Figure 2 The support layer 1 is semi-enclosed and made of high-density EVA material. The contact layer 2 and the shock-absorbing layer 3 are fixed with adhesive, and the shock-absorbing layer 3 is made of low-density EVA material. The contact layer 2 includes anti-slip patterns 201, which are formed on the surface of the top side of the contact layer 2. Specifically, through the partitioned structure design, the sole can have high cushioning, high rebound and stable support performance without adding extra weight, meet the needs of high-intensity sports, improve wearing comfort and sports performance, and effectively extend the service life of the sole.

[0025] The working principle of this utility model is as follows: When in use, the foot first comes into contact with the contact layer 2. The top of the contact layer 2 is provided with anti-slip texture 201, which can enhance the friction between the foot and the insole, prevent the foot from slipping during exercise, and improve the fit and comfort. At the same time, the pressure applied by the foot is evenly transmitted to the shock-absorbing layer 3 through the contact layer 2. The shock-absorbing column 301 deforms when subjected to force, absorbs and disperses the impact energy, effectively reduces the impact on the foot, and improves the shock absorption effect. Meanwhile, the cushioning plate 302 further optimizes the force distribution, reducing foot fatigue during high-intensity exercise and improving the overall comfort and durability of the sole; As the impact force continues to be transmitted downwards, the support layer 1 comes into play. The support layer 1 has an impact absorption zone 101 and an energy feedback zone 102 inside. The impact absorption zone 101 can effectively disperse the impact force when landing, prevent excessive deformation of the sole, and enhance stability. The energy feedback zone 102 stores some impact energy and releases it when pushing off the ground, providing additional rebound force and improving the athlete's starting speed and jumping ability. Furthermore, the engagement of the impact absorption zone 101 and energy feedback zone 102 with the shock absorption column 301 and buffer plate 302 further enhances the synergistic effect of each functional area, preventing misalignment between the insole and the sole during vigorous exercise, thereby enhancing overall stability and durability. Through a partitioned structural design, the sole provides high cushioning, high rebound, and stable support without adding extra weight, meeting the needs of high-intensity sports, improving wearing comfort and athletic performance, and effectively extending the lifespan of the sole.
