Description

TECHNICAL FIELD

[0001] The utility model relates to rubber shoe sole technical field, concretely relates to a high compression resistance rubber shoe sole. BACKGROUND

[0002] With the development of society and economy, people's life rhythm is faster and faster, especially in some big cities basically everybody is busy all day, and people have to catch the bus after washing up in the morning. Sports shoes generally adopt EVA foaming material with light quality and good resilience, so that sports shoes are pursued by everyone due to their lightness, flexibility, comfort and other performances. Moreover, with the development of science and technology, more and more shoe manufacturers combine the latest human body structure with shoes, and set up a series of sports shoes integrating comfort and softness and strong durability, so as to further expand the market share of sports shoes.

[0003] Through retrieval, the patent with the patent application number CN202320187632.8 discloses a shoe sole with high elastic and anti-wrinkle functions, which comprises a midsole assembly and an outsole arranged on the outer side wall and the bottom of the midsole assembly. The midsole assembly comprises a low-density midsole core part and a high-density midsole outer edge part. Although the device can balance the support stability and the resilience performance to a certain extent by setting the midsole structure with different densities, such as the midsole outer edge part is conducive to realizing the support stability of the shoe sole, and the midsole core part can increase the compression deformation amplitude of the shoe sole material under pressure, helping the wearer to improve the sports performance, but the device still has some deficiencies when in use. The adaptability to complex motion scenes is poor, and only relying on the density difference of the midsole cannot cope with diversified stress conditions such as twisting during running and instantaneous impact force during jumping, so it cannot disperse and absorb forces in different directions in all directions. Moreover, the shoe sole is lacking in compression resistance durability, and the compression deformation recovery ability of the midsole material decreases after long-term frequent use, which affects the long-term play of the high elastic performance and the support effect. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies of the prior art, the utility model provides a high compression resistance rubber shoe sole, which solves the problems in the background art.

[0005] The utility model solves the technical problems in the above-mentioned scheme as follows:

[0006] A high compression resistance rubber shoe sole, comprising a shoe sole, an upper layer of fabric is arranged at the top end of the shoe sole,

[0007] A cavity is formed in the shoe sole, a heel shock absorption unit is installed in the cavity through a limiting seat, an arch support block is arranged in front of the heel shock absorption unit in the cavity, and a forefoot support unit is installed on the side of the arch support block away from the heel shock absorption unit in the cavity.

[0008] On the basis of the above technical solutions, the utility model further can make improvement as follows.

[0009] Further, the limiting seat is provided with a connecting rod, support fins are uniformly distributed on the connecting rod, and connecting seats are arranged at both ends of the connecting rod and symmetrically distributed at both ends of the heel damping unit.

[0010] The beneficial effects of the above further scheme are:

[0011] The connecting rod of the limiting seat and the symmetrically distributed connecting seats at both ends can stably connect the heel damping unit, prevent the heel damping unit from being randomly displaced in the shoe sole cavity, ensure the precise position of the damping unit, and always effectively play a role.

[0012] Further, the plurality of heel damping units are supported and separated by the connecting rod and the support fins.

[0013] The beneficial effects of the above further scheme are:

[0014] The plurality of heel damping units are supported and separated by the connecting rod and the support fins, forming an orderly arrangement structure.

[0015] Further, the heel damping unit is composed of a plurality of flexible wave rib plates, and adjacent two flexible wave rib plates are distributed in a staggered manner.

[0016] The beneficial effects of the above further scheme are:

[0017] The flexible corrugated ribs employ a standard sine wave pattern with specific wavelength and amplitude, and are arranged in a three-dimensional grid with staggered phase differences, greatly enhancing shock absorption performance. When the heel is subjected to force, the corrugated ribs at different positions undergo elastic deformation sequentially according to a specific phase difference, absorbing impact energy from multiple angles and at different times, thus dispersing the impact force. The staggered distribution of adjacent corrugated ribs further increases the force contact points and buffer paths, making the shock absorption process more refined and comprehensive, effectively reducing the impact on the feet and knees, and providing users with a more comfortable and stable sports experience.

[0018] Furthermore, the forefoot support unit is composed of multiple flexible honeycomb panels, and the forefoot support unit has a 15° forward tilt angle along the longitudinal axis of the foot arch, with the top of the forefoot support unit tilted towards the toes.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The 15° forward tilt angle of the forefoot support unit precisely matches the angle at which the foot exerts force when walking or exercising. When the foot pushes off the ground, the forefoot support unit can better adapt to the force exertion, efficiently absorbing and distributing forefoot pressure. The structure composed of multiple flexible honeycomb panels provides stable support while absorbing and storing the energy generated during push-off due to the elasticity of the honeycomb structure. This energy is released at the moment of foot lift, assisting in propelling the body forward, reducing forefoot muscle fatigue, improving walking or exercise efficiency, and providing comprehensive, scientifically sound support and assistance for the forefoot.

[0021] This invention provides a highly elastic, compression-resistant rubber shoe sole. It has the following beneficial effects:

[0022] The heel shock absorber consists of multiple flexible corrugated ribs arranged in a standard sine wave pattern, forming a three-dimensional grid through phase differences. This structural design effectively disperses the impact force on the heel, providing users with excellent shock absorption, reducing damage to the feet and knees during exercise or walking, and improving comfort. For example, during strenuous activities such as running, where the heel strikes the ground frequently, the heel shock absorber effectively cushions the impact.

[0023] Multiple heel cushioning units are supported and separated by connecting rods and support fins. Limiting seats and connecting seats are symmetrically distributed at both ends of the heel cushioning units, making the entire heel structure more stable. At the same time, the connecting rods and support fins can evenly distribute pressure, enhancing the support performance of the sole, helping to maintain the normal posture of the foot, and reducing fatigue and discomfort caused by insufficient sole support.

[0024] Located in front of the heel shock absorber is an arch support block. This block provides effective support for the arch, reducing pressure on it during exercise or walking and preventing arch collapse. It is suitable for people who stand or walk for long periods. For those with flat feet or high arches, the arch support block provides better fit and support, enhancing comfort.

[0025] The forefoot support unit consists of multiple flexible honeycomb plates with a forward tilt angle along the longitudinal axis of the arch, sloping towards the toes at the top. This design conforms to ergonomic principles, and the forward tilt angle better adapts to the forward movement of the foot, providing good support and cushioning for the forefoot during walking or running. This helps propel the body forward, reducing the burden on the forefoot, while the flexible honeycomb plate structure also increases the elasticity and comfort of the sole.

[0026] The top of the sole features an upper fabric that comes into direct contact with the foot, providing a comfortable feel. The layered design of the heel cushioning unit, arch support block, and forefoot support unit inside the sole provides targeted support and cushioning based on the stress characteristics and functional needs of different parts of the foot. The overall design conforms to the physiological structure of the foot, providing a comprehensive comfort experience. Attached Figure Description

[0034] 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.

[0035] Please see Figs. 1-3 As shown, the embodiments provided by this utility model are as follows:

[0036] Example 1: A high-elasticity, compression-resistant rubber sole includes a sole 4, with an upper fabric 6 at the top of the sole 4. A cavity 401 is formed inside the sole 4, and a heel shock-absorbing unit 1 is installed inside the cavity 401 via a limiting seat 2. The limiting seat 2 has a connecting rod 201, with supporting fins 202 evenly distributed on the connecting rod 201. Connecting seats 203 are provided at both ends of the connecting rod 201, and the connecting seats 203 are symmetrically distributed at both ends of the heel shock-absorbing unit 1. The connecting rod 201 of the limiting seat 2 and the symmetrically distributed connecting seats 203 at both ends can securely connect the heel shock-absorbing unit 1, preventing it from shifting randomly within the cavity 401 of the sole 4, ensuring that the shock-absorbing unit is accurately positioned and always functions effectively. The evenly distributed support fins 202 on the connecting rod 201 greatly increase the contact area with the internal space of the sole 4. While dispersing pressure, they enhance the overall structural stability, allowing the heel part of the sole 4 to share the force when subjected to external impact, avoiding damage caused by uneven local force distribution, and extending the service life of the sole 4. Multiple heel shock absorption units 1 are supported and separated by the connecting rod 201 and the support fins 202, forming an orderly arrangement structure. On the one hand, this structure allows each shock-absorbing unit to independently perform its buffering function while also working together. When a unit is subjected to a large impact, the connecting rod 201 and support fins 202 can disperse some of the force to other units, improving the overall shock absorption effect. On the other hand, the orderly arrangement of the units prevents them from squeezing or interfering with each other, maintaining their elastic deformation space and ensuring that the performance of each unit remains stable during long-term use, continuously providing good shock absorption protection for the feet. The heel shock-absorbing unit 1 consists of multiple flexible corrugated ribs, with adjacent ribs staggered. The flexible corrugated ribs adopt a standard sine wave pattern with a wavelength of 8mm and an amplitude of 2mm, and are arranged in a staggered manner with a phase difference of 30° to form a three-dimensional grid. The use of a standard sine wave pattern with a specific wavelength and amplitude, and the staggered arrangement with a phase difference to form a three-dimensional grid, greatly enhances the shock absorption performance. When the heel is subjected to force, the corrugated ribs at different positions undergo elastic deformation sequentially according to a specific phase difference, absorbing impact energy from multiple angles and at different times, thus dispersing the impact force. The staggered distribution of adjacent wave-shaped stiffeners further increases the force contact points and buffer paths, making the shock absorption process more delicate and comprehensive, effectively reducing the impact on the feet and knees, and bringing users a more comfortable and stable sports experience.

[0037] Example 2: To reduce forefoot muscle fatigue and improve walking or exercise efficiency, and to provide comprehensive and scientifically sound support and assistance to the forefoot, for example, such as... Figs. 1-3As shown, this utility model also includes: an arch support block 3 located in front of the heel shock absorber 1 within the cavity 401; a forefoot support unit 5 installed on the side of the arch support block 3 away from the heel shock absorber 1 within the cavity 401; the forefoot support unit 5 is composed of multiple flexible honeycomb panels, and the forefoot support unit 5 has a 15° forward tilt angle along the longitudinal axis of the arch, with the top of the forefoot support unit 5 tilting towards the toes. The 15° forward tilt angle design of the forefoot support unit 5 precisely matches the angle at which the foot exerts force forward during walking or exercise. When the foot pushes off the ground forward, the forefoot support unit 5 can better adapt to the force exertion trend, efficiently bearing and dispersing forefoot pressure. The structure composed of multiple flexible honeycomb panels provides stable support while absorbing and storing the energy generated during push-off due to the elasticity of the honeycomb structure, releasing it the moment the foot lifts, assisting in propelling the body forward, reducing forefoot muscle fatigue, improving walking or exercise efficiency, and providing comprehensive, scientific, and reasonable support and assistance for the forefoot.

[0038] Working principle:

[0039] When people begin walking or exercising, the heel is usually the first part to contact the ground. This is when the heel damping unit 1 begins to function. The heel damping unit 1 consists of multiple flexible corrugated ribs arranged in a standard sine wave pattern, forming a three-dimensional grid with phase differences. Its working principle is that when the heel is subjected to an upward impact force from the ground, the flexible corrugated ribs, through their elasticity and unique wave structure, disperse and buffer the impact force. These corrugated ribs undergo elastic deformation under stress, absorbing impact energy and thus reducing the impact on the feet and knees.

[0040] As the foot moves forward, the arch of the foot gradually bears the load. The arch support block 3, located in front of the heel damping unit 1, begins to function, providing stable support for the arch based on its physiological structure. The arch plays a vital role in cushioning and supporting the body during movement. By conforming to the shape of the arch, the arch support block 3 distributes the pressure on the arch, maintains its normal shape, prevents fatigue or collapse due to excessive stress, and ensures foot stability during exercise.

[0041] Next, the forefoot contacts the ground and bears the forward momentum of the body. The forefoot support unit 5 consists of multiple flexible honeycomb panels, which are tilted forward at a certain angle along the longitudinal axis of the arch, with the top inclined towards the toes. The working principle is that the forward tilt design allows the forefoot support unit 5 to better adapt to the forward movement of the foot. When the foot pushes off the ground, the flexible honeycomb panel structure provides good support and distributes the pressure on the forefoot; on the other hand, its elasticity deforms under force, absorbing and storing some energy, and then releasing energy when the foot is lifted, assisting in propelling the body forward, reducing the burden on the forefoot, and improving the efficiency of walking or exercise.

[0042] The rubber material throughout the sole 4 possesses high elasticity and compression resistance, a characteristic that is maintained throughout the entire shoe. Throughout the exercise, the rubber material ensures that all components of the sole 4 can quickly return to their original shape after repeated stress, maintaining good elasticity and cushioning performance, thus ensuring the lifespan of the sole 4. Meanwhile, the upper fabric 6 at the top of the sole 4 is in direct contact with the foot, providing a comfortable feel and working in conjunction with the internal support and shock-absorbing components of the sole 4 to provide the user with a comprehensive comfort experience.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
