TECHNICAL FIELD

[0001] The utility model relates to a shoe field especially relates to a shoe sole and contain the shoe of this shoe sole. BACKGROUND

[0002] With the development of modern sports science, athletes have higher and higher performance requirements for sports equipment. High-performance sports equipment not only protects athletes from injury, but also improves sports performance, especially in sports such as running and basketball that require rapid extension. The design and technology of the shoe sole are crucial to improving the performance of athletes. These designs aim to optimize energy feedback, so that each extension can be more efficiently converted into forward power.

[0003] Currently, although the midsole material of the shoe provides good shock absorption effect, its rebound performance is relatively weak, and most running shoes can only feedback 50%-60% of the energy. This means that during running, a considerable amount of energy is absorbed by the shoe and converted into heat energy, and the shoe integrates complex structures and technologies, such as carbon fiber plates, etc. However, the application of these technologies may increase the overall weight of the shoe, thereby affecting the running economy. In addition, even if some shoes use some new midsole materials, theoretically, they can achieve higher energy feedback rates, but in actual application, due to manufacturing process limitations or material aging, the actual efficiency may be lower than laboratory data. Therefore, the current shoe has the disadvantages of low extension efficiency and large energy loss. SUMMARY

[0004] The utility model aims at providing a shoe sole and a shoe containing the shoe sole, which concentrates the energy when the human foot lands to improve energy conversion efficiency. The specific technical solution is as follows:

[0005] A shoe sole includes a momentum transfer module, which includes a plurality of elastic feedback components arranged longitudinally. The mass of the plurality of feedback components increases from top to bottom. In the two adjacent feedback components, the lower feedback component can transmit the absorbed energy upward and release it quickly through the upper feedback component.

[0006] Further, the volume of the plurality of feedback components increases from top to bottom.

[0007] Further, the two adjacent feedback components are arranged to be separable.

[0008] Further, the line connecting the centers of mass of the plurality of feedback components is perpendicular to the shoe sole.

[0009] Further, the momentum transfer module comprises a first feedback component and a second feedback component located below the first feedback component, the elasticity of the first feedback component is greater than the elasticity of the second feedback component, and / or the structural strength and toughness of the second feedback component is greater than the structural strength and toughness of the first feedback component.

[0011] Further, the fluid material comprises a buffer bag and a filler, the filler comprises a gas, a liquid or a plurality of particles, and the filler is arranged in the buffer bag.

[0012] Further, the solid material is at least one of rubber, thermoplastic polyurethane elastomer, polyurethane foam material, polystyrene foam material and polyethylene foam material.

[0013] Further, the sole comprises a midsole, and the midsole comprises a receiving cavity, and the momentum transfer module is arranged in the receiving cavity of the midsole.

[0014] A shoe comprises the above-mentioned sole.

[0015] The sole has the following advantages.

[0016] 1. By arranging the momentum transfer module in the sole, the principle of Galileo's cannon is used to convert the gravity and potential energy in the extension stage into kinetic energy, and the potential energy when the human body lands is maximized to convert into kinetic energy in the extension stage, so as to improve the movement performance of the human body.

[0022] Figure 4 Figure 2 is a schematic view of a shoe sole according to a second comparative example of the present application. DETAILED DESCRIPTION

[0023] In order to better understand the purpose, structure and function of the present application, the shoe sole and shoe of the present application will be described in detail below with reference to the specific structure of the shoe sole and in conjunction with the accompanying drawings.

[0024] As shown in Figure 1 and Figure 2 , the side of the shoe sole body close to the human foot is defined as the upper side of the shoe sole body, and the side of the shoe sole body away from the human foot is defined as the lower side of the shoe sole body. The line connecting the upper side and the lower side is the longitudinal direction of the shoe sole body, and the corresponding shoe sole position of the longitudinal direction is in a vertical position relationship. The vertical relationship includes not only absolute vertical, but also vertical relationship with a small deviation angle. Therefore, the shoe sole includes a midsole and an outsole stacked from top to bottom.

[0025] In the first embodiment, as shown in Figure 1 , the midsole is a full-palm structure, which includes a forefoot region, a midfoot region and a heel region arranged in sequence. A receiving chamber is arranged on the forefoot region, and a momentum transfer module is arranged in the receiving chamber to achieve the best stretch effect. The momentum transfer module uses the principle of Galileo's cannon to convert the gravity and potential energy of the stretch stage into kinetic energy through the momentum transfer module, and maximizes the conversion of the potential energy of the human body landing into the kinetic energy of the stretch. That is, the energy of the human foot landing is concentrated and fed back to the stretch part of the forefoot to improve the performance of the human body. The core structure of the momentum transfer module is a double-layer structure stacked from top to bottom. The volume and mass of the lower layer are greater than those of the upper layer. At the same time, the direction of the center of mass connecting line, the force received and the reaction force in the momentum transfer module are located on the same straight line to improve the energy conversion efficiency.

[0026] Of course, the center of mass connecting line, the force received and the reaction force can be directed in different directions. In the present embodiment, the center of mass connecting line is perpendicular to the shoe sole of the region, so as to fully absorb the force applied by the human body from top to bottom in the stretch stage, and more efficiently and quickly release the energy upward, thereby on the one hand improving the stretch efficiency, increasing the jumping height and speed of the human body, and on the other hand concentrating the energy feedback through the linear position relationship of the center of mass, and reducing the energy loss in the movement process.

[0027] It can be understood that the accommodation chamber can also be arranged in the midfoot region and the heel region of the midsole, and can be arranged simultaneously in multiple regions, and then the momentum transfer module is arranged in the corresponding accommodation chamber, so as to improve the energy conversion efficiency of multiple stress positions of the whole palm.

[0028] It should be noted that the momentum transfer module can be provided with three or more feedback components, which are also arranged in a longitudinal stacking manner. The mass of the multiple feedback components increases from top to bottom, the volume of the multiple feedback components increases from top to bottom, in two adjacent feedback components, the lower feedback component can transmit the absorbed energy upward, and the energy is quickly concentrated and released through the upper feedback component. The direction of the center of mass line, the acting force and the reaction force of the multiple feedback components are located on the same straight line. Preferably, the center of mass line is perpendicular to the sole to ensure the linearity and efficiency of energy transmission. In this embodiment, the preferred momentum transfer module is a double-layer structure stacked from top to bottom. On the one hand, the structure is more stable and the energy transmission speed is fast. On the other hand, the structure is simple, and the material and assembly costs are reduced.

[0029] Specifically, the momentum transfer module includes a first feedback component 110 and a second feedback component 210 arranged in a stacking manner from top to bottom. The mass of the second feedback component 210 is greater than the mass of the first feedback component 110. When the human body is in the landing stage, the second feedback component 210 is used to absorb the impact energy generated in the direction of the sole when landing, and then releases the energy to the first feedback component 110 through the reaction force. The first feedback component 110 also absorbs the impact energy generated in the direction of the sole when landing in the landing stage. When the first feedback component 110 releases energy, it receives a reaction force from the second feedback component 210. The reaction forces of the two are superimposed, and the energy is quickly concentrated and fed back to the forefoot of the human foot. This reduces the energy loss during movement, thereby improving the extension efficiency and increasing the jumping height and speed of the human body.

[0030] Preferably, the accommodation chamber is arranged on the upper of the midsole, the first feedback component 110 and the second feedback component 210 are arranged in close contact, the momentum transfer module is arranged in the accommodation chamber, the accommodation chamber limits the momentum transfer module in the horizontal direction, and the momentum transfer module is arranged between the human foot and the outsole in the longitudinal direction. Therefore, the momentum transfer module is relatively fixed in the accommodation chamber, the first feedback component 110 and the second feedback component 210 are arranged in abutment with each other while maintaining a separable connection, so that when the energy is released in the longitudinal direction, the first feedback component 110 quickly separates from the second feedback component 210, the energy is concentrated and released quickly through the first feedback component 110, and the energy feedback efficiency is improved. Of course, for the feedback components arranged in three or more layers, any two adjacent feedback components are arranged in abutment with each other while maintaining a separable connection, so that the energy is transmitted efficiently.

[0031] Preferably, the elasticity of the first feedback component 110 is greater than the elasticity of the second feedback component 210, so that in the energy release stage, the first feedback component 110 quickly transmits energy to the human foot bottom, and the structural strength and toughness of the second feedback component 210 are greater than those of the first feedback component 110, which can provide a stable bottom structure for the momentum transfer module, while having sufficient elasticity to store and quickly release energy. It can be understood that in the embodiment, the elasticity of the first feedback component 110 is greater than that of the second feedback component 210, and the structural strength and toughness of the second feedback component 210 are greater than those of the first feedback component 110. Only one of the material properties can also be used, and the technical effects of efficient energy absorption and feedback can also be basically achieved.

[0032] Further, each feedback component can adopt different shapes and materials to adapt to different movement needs and improve the adaptability of the module. In the embodiment, the first feedback component 110 and the second feedback component 210 are preferably flat spherical structures with a longitudinal diameter smaller than a horizontal diameter. This shape has better support and energy concentration and rebound effects. Other spherical or ellipsoidal structures or other spherical structures can also be selected.

[0033] In the embodiment, the second feedback component 210 adopts a whole material, i.e., a solid material, such as at least one of common foaming materials or elastomers, i.e., rubber, thermoplastic polyurethane elastomer, polyurethane foaming material, polystyrene foaming material, and polyethylene foaming material. The whole material can improve the stability and durability of the feedback component structure.

[0034] The shapes and materials of the first feedback component 110 and the second feedback component 210 in the embodiment can enhance the rebound performance of the momentum transfer module, making the energy concentration and release effect better. When the human body is in the landing stage, the second feedback component 210 first absorbs impact energy and deforms, and then the first feedback component 110 quickly absorbs and feeds back these energy to the foot bottom of the human body, achieving rapid energy conversion and release.

[0035] It can be understood that those skilled in the art can customize the design of the material, shape, and size of the feedback component in the momentum transfer module according to the weight of different human bodies, movement types, and personal preferences, to achieve the best performance and comfort.

[0036] Embodiment two, as Figure 2As shown, the structure and position of the momentum transfer module in the embodiment are the same as those in embodiment one, and the difference is that the second feedback component 220 in the embodiment adopts a fluid material. Specifically, the second feedback component 220 includes a buffer bag and a plurality of particles, the particles are filled in the buffer bag, and the particles in the buffer bag can change the shape of the second feedback component 220, thereby providing better energy absorption effect and having the characteristics of concentrated and directional energy release. Of course, the second feedback component 220 can also adopt other fluid materials, such as filling gas, water or oil in the buffer bag, or selecting other suitable materials according to the actual application scene and requirements. The first feedback component 120 adopts a whole piece of material, i.e. a solid material, such as a common foaming material or an elastomer.

[0037] It should be noted that when the second feedback component 220 is made of a fluid material, the Worthington jet principle can be generated, i.e. when an object hits a liquid surface at a high speed, a liquid jet phenomenon is formed opposite the impact point. When the first feedback component 120 hits the fluid material of the second feedback component 220, the jet formed by the second feedback component 220 enhances the impact on the first feedback component 120, and further superimposes the energy released by the second feedback component 220, so that the first feedback component 120 collects more energy for concentrated release.

[0038] The utility model also provides a shoe, contain vamp and above described shoe sole.

[0039] In order to verify the performance of the shoes in the above embodiment one and embodiment two, comparative example one as shown in Figure 3 and comparative example two as shown in Figure 4 are selected as test sample shoes for comparison test. The momentum transfer module of the comparative test sample shoes is different from that in the shoes of the above embodiments, and other structures and materials remain the same. The specific difference is that the momentum transfer module of the comparative test sample shoes includes a upper feedback component and a lower feedback component arranged in layers. The upper feedback component adopts a material with large mass, high strength and high toughness, which is used to absorb the impact energy when landing. The lower feedback component has small volume and mass, which is used to feedback the energy absorbed by the lower layer to the upper feedback component. The material selection of the lower feedback component focuses on light weight and high elasticity, so that the energy is quickly transmitted upward.

[0040] As shown in Figure 3 , the upper feedback component 310 adopts a solid material, and the lower feedback component 410 also adopts a solid material, which is compared with the shoe shown in embodiment one in Figure 1 . As shown in Figure 4 , the upper feedback component 320 adopts a fluid material, and the lower feedback component 420 adopts a solid material, which is compared with the shoe shown in embodiment two in Figure 2 .

[0041] The impact resilience test comparison results of the examples and the comparative examples are as follows:

[0042] Metatarsal- Energy Return (%) Example One 86 Comparative Example One 72.6 Example Two 85 Comparative Example Two 69.8

[0043] In the above table, the energy regression represents resilience, and the larger the value is, the better the resilience performance is.

[0044] The shoe sole has the following advantages:

[0045] 1. By setting a momentum transfer module in the shoe sole, the principle of Galileo's cannon is used to convert the gravity and potential energy in the extension stage into kinetic energy, and the potential energy when the human body lands is maximized to convert into kinetic energy in the extension stage, so as to improve the human body's sports performance.

[0046] 2. The volume and mass of the lower layer of the momentum transfer module are greater than those of the upper layer, and the directions of the center of mass line, the acting force and the reaction force in the momentum transfer module are located on the same straight line, so that the energy is concentrated and fed back, and the energy loss in the movement process is reduced.

[0047] 3. The second feedback component uses a fluid material and uses the Worthington jet principle. When the first feedback component impacts the fluid material of the second feedback component, the jet formed by the second feedback component enhances the impact on the first feedback component, further superimposes the energy released by the second feedback component, and makes the first feedback component collect more energy for concentrated release, so as to improve the energy conversion efficiency.

[0048] The above-mentioned "above", "below" and "within" include the number; the "more than" and "outside" do not include the number.

[0049] The above further describes the utility model by means of specific embodiments, but it should be understood that the specific description herein should not be understood as limiting the essence and scope of the utility model, and various modifications of the above embodiments made by ordinary skilled persons in the art after reading the specification all belong to the scope protected by the utility model. In the above specific implementation, each specific technical feature described in the above specific implementation can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, various possible combination modes of the utility model embodiments are not described again.
