Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shoes, in particular to a support structure and a sole with enhanced hard plate lever effect and energy rebound function. BACKGROUND

[0002] Carbon plate running shoes are widely used in marathon athletes and ordinary long-distance runners, which are embedded with a carbon plate with a certain hardness in the midsole. During walking, the arc on the carbon plate is used as a fulcrum to form a "lever effect" in the sole, increasing the energy rebounding ability of the sole to the foot, reducing the weight of the sole while increasing the longitudinal axis bending stiffness of the forefoot, effectively improving the running efficiency. However, most of the carbon plates are only provided with an arc in the forefoot part, and the shape is closer to a "spade", and the carbon plate is directly arranged on the soft and elastic midsole foam. When the running speed is relatively fast, the forefoot is in a completely flattened state due to the relatively soft midsole, which greatly reduces the "lever effect", and the support and elasticity of the carbon plate cannot fully play a role. SUMMARY

[0003] Other features and advantages of the present application will be set forth in the following specification, and in part will become apparent to those skilled in the art upon examination of the specification or can be learned by practice of the application. The objects and other advantages of the application will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

[0004] The present application aims to overcome the above-mentioned shortcomings, and provides a support structure and a sole with enhanced hard plate lever effect and energy rebound function, which has the advantages of large compression stiffness and good elasticity, further enhances the lever effect of carbon plate or hard plate running shoes similar to carbon plate, improves the energy rebound efficiency, and effectively reduces the forward movement of the human body.

[0005] In a first aspect, the present application provides a support structure with enhanced hard plate lever effect and energy rebound function, which is arranged in the sole and includes a support plate and an elastic cylindrical body. The support plate is arched downward at the forefoot to form a first arc-shaped groove; the elastic cylindrical body is arranged below and / or behind the lowest point of the first arc-shaped groove in the transverse direction of the forefoot, and the elastic cylindrical body is used to enhance the lever effect of the support plate.

[0006] The support plate has a certain hardness and is arranged in the shoe sole to increase the longitudinal bending stiffness of the shoe sole. The first arc-shaped groove is arched downward, and the lowest point can be used as a fulcrum. An elastic cylindrical body with small compressibility is arranged below or behind the lowest point of the first arc-shaped groove, which can enhance the fulcrum effect of the first arc-shaped groove. When the ankle joint is neutral, the foot exerts a downward force on the support plate, causing the forefoot of the support plate to be pressed. The elastic cylindrical body as the fulcrum lifts the position of the forefoot, so that the lowest point of the forefoot of the support plate forms a convex shape, increasing the deformation potential energy of the support plate and the elastic cylindrical body. When the vertical line of the body center of gravity moves to the forefoot, the seesaw effect of the hard plate begins to work. While the forefoot continues to press the forefoot of the shoe, the hard plate exerts a force on the heel of the foot. As the body center of gravity moves forward further, the direction of the force on the heel of the foot gradually changes from upward to forward. That is, the support plate rotates around the elastic cylindrical body as the fulcrum, and the end close to the toe is pressed down to pry the other end close to the heel. At the same time, the compressed elastic cylindrical body and the support plate recover the deformation, and add a forward and upward force to the heel of the foot. Finally, under the combined action of the rebound of the elastic body, the rebound of the hard plate and the lever effect of the hard plate, the energy rebound efficiency is maximized, the forward running driving force is effectively increased, and the running time is greatly shortened.

[0007] In some embodiments, the elastic cylindrical body includes an outer shell and a core wrapped inside the outer shell. The entire elastic cylindrical body has a capsule structure, and different materials can be selected according to the target requirements, thereby increasing the selection range of materials.

[0008] In some embodiments, the core is polyborosiloxane particles, high-elasticity foaming beads, or a gas filled in the outer shell. The polyborosiloxane has good impact resistance and buffering and energy absorption effects, and the high-elasticity foaming beads increase the high elasticity and self-adaptation of the elastic cylindrical body, so that the elastic cylindrical body has large compression rigidity and good elasticity, further increasing the lever effect of the support plate and improving the energy rebound efficiency.

[0009] In some embodiments, the mass ratio of the polyborosiloxane particles to the high-elasticity foaming beads is 20-30:1. By selecting a suitable ratio of the polyborosiloxane particles to the high-elasticity foaming beads, an elastic cylindrical body with moderate compression rigidity and elasticity is obtained.

[0010] In some embodiments, the core is polyborosiloxane particles, high-elasticity foaming beads, and a gas filled in the outer shell. The injection of air makes the mixture of the core more uniform, the filling more full, and the energy rebound efficiency higher.

[0011] In some embodiments, the mass ratio of the polyborosiloxane particles to the high-elasticity foaming beads is 20-30:1, and the volume ratio of the gas to the core is ≤1:5. By selecting a suitable ratio of the polyborosiloxane particles, the high-elasticity foaming beads, and air, an elastic cylindrical body with moderate compression rigidity and elasticity is obtained.

[0012] In some embodiments, the radial length of the elastic cylinder is 0.8cm-3cm, the radial width is 0.8cm-2cm, and the axial length is 4cm-8cm. By selecting a suitable size for the elastic cylinder to fit the curved surface of the first arc-shaped groove, the enhanced leverage effect is maximized.

[0013] In some embodiments, the number of elastic cylinders is one. One elastic cylinder saves manufacturing steps and increases the stress deformation range of the elastic cylinder.

[0014] In some embodiments, the number of elastic cylinders is at least two, and every two elastic cylinders are arranged side by side, either front to back or side to side. When there are two elastic cylinders, they can be arranged side by side to form a row, and the position of the elastic cylinders can be set according to the different pressure points of the foot to enhance the effect more significantly. Alternatively, they can be arranged side by side to form two rows, in which the cylinders can strengthen the leverage effect. When there are four elastic cylinders, every two elastic cylinders arranged side by side are arranged side by side to form a grid pattern.

[0015] In some embodiments, the radial height difference between any two elastic cylinders arranged side-by-side is 0.5cm-1cm. The two parallel elastic cylinders have different base areas, creating a height difference. Each cylinder is tangent to the first arc-shaped groove. The cylinder with the smaller base area acts as a fulcrum directly below the lowest point of the support plate, while the cylinder with the larger base area is located directly below and behind it. This elasticity increases the rotational capacity of the support plate and enhances its leverage effect.

[0016] In some embodiments, the shell is made of PU material. PU material is lightweight, flexible, and not easily deformed or broken after compression.

[0017] In some embodiments, the support plate arches upward at the arch of the foot to form a second arc-shaped groove, and arches downward at the heel to form a third arc-shaped groove. The sufficient upward arch provides a better ergonomic fit, while the downward arch at the heel creates a reverse arch shape for the entire support plate. This allows both the forefoot and heel to compress and store power when standing, further increasing the force during push-off and reducing foot pressure.

[0018] In some embodiments, the support plate is a carbon fiber plate. Carbon composite fiber is lighter and has a certain degree of hardness and good toughness, making it not easy to break while providing support.

[0019] In a second aspect, the application provides a shoe sole, comprising a midsole and an outsole, and further comprising any one of the support structures having the enhanced lever effect and energy rebound function as described above, the support structure comprising a support plate and an elastic column body, the support plate being arranged in the midsole, and the elastic column body being arranged between the midsole and the outsole. The elastic column body is directly connected to the outsole instead of being arranged in the midsole, so that the rebound effect caused by the material of the midsole can be prevented from being not obvious.

[0020] In some embodiments, the side end of the elastic column body extends to the inner side wall of the outsole and is flush with the inner side wall of the outsole. The elastic member transversely penetrates through the entire forefoot, so as to be fixed, and is also more suitable for different walking postures.

[0021] In some embodiments, the side end of the elastic column body is spaced apart from the inner side wall of the outsole. The elastic column body can be designed to have a force point according to different force points of the left and right feet, so as to reduce the manufacturing cost.

[0022] By adopting the technical solutions described above, the application has the following beneficial effects:

[0023] 1. By arranging the elastic column body below the first arc-shaped groove, the elastic body has a greater compression stiffness than the surrounding midsole material. During walking, the support plate is deformed to be convex at the forefoot position, the elastic potential energy of the support plate is increased, the lever effect of the support plate is further increased, the lever effect is superimposed with the elastic potential energy of the support plate and the elastic column body, the energy rebound efficiency is maximized, the foot is pushed to move forward, and the running result is greatly improved.

[0024] 2. By adopting polysiloxane and high-elastic foaming beads as raw materials to prepare the capsule-shaped elastic column body, the compression stiffness of the elastic column body is large, the energy rebound is high, the elastic effect of the support plate is further increased, and the energy rebound efficiency of the overall structure is improved.

[0083] Experimental test

[0084] Test 1: Elastic cylindrical body impact test

[0085] Experimental content: The elastic cylindrical body in the embodiment 1 and the ordinary midsole are selected as the test objects for comparison experiment. A 8.5 kg weight is selected to perform free fall motion at a height of 5 cm from the test object. The compressed distance of the test object thickness, the corresponding force and the compression time are recorded. The compressed distance of the test object thickness is taken as the horizontal axis with unit of mm, and the corresponding force is taken as the vertical axis with unit of N. The points are plotted and the graph is drawn to obtain Figure 8 . Table 1 is further calculated.

[0086] Table 1: Test data table of elastic cylindrical body and ordinary midsole in embodiment 1

[0087] Maximum acceleration (g) Compression time (ms) Maximum compression rate (%) Rebound ability rate (%) Elastic column 19.12 8.33 48.26 74.53 Normal midsole 12.51 20.27 76.17 63.94

[0088] Conclusion: Referring to Figure 8 , Figure 8For the impact test graph, it can be obtained that 400N external force is needed in the compression interval of 7mm-15mm of the pendulum movement, however, 1850N external force is needed when the pendulum movement is 15mm-19mm, thus it can be seen that the compression rigidity of the elastic column body is large and it is not easy to be compressed; combined with the data in Table 1, it can be obtained that the maximum compression rate of the elastic column body prepared in the application is smaller than that of the ordinary midsole, and the compression time is shorter and the rebounding capacity is better. Thus it can be judged that the compression rigidity of the elastic column body in the application is large and the energy rebounding is high.

[0089] Test two: human biomechanics test

[0090] Experimental content: the shoes made of the shoe sole in Example 1 and the shoes made of ordinary shoe sole were selected for comparative experiment, the same user wore different shoes in turn at a running speed of about 6.33m / s and carried out running test in the instrument, the running time and the size of the vertical component of the reaction force corresponding to the time were recorded, and the time was taken as the horizontal axis, the size of the vertical component of the reaction force corresponding to the time was taken as the vertical axis, the positive and negative signs represented the direction of force, the upward direction perpendicular to the shoe sole was defined as the positive direction, and the dotting and plotting were carried out to obtain Figure 9 . In this way, under the condition that other conditions were the same, the running speed of the user was changed to about 4.7m / s, and Figure 10 was obtained.

[0091] Conclusion: referring to Figures 9-10 , Figure 9 is the vertical component of the ground reaction force in running with time Figure 1 ; Figure 10 is the front and back direction component of the ground reaction force in running with time Figure 2 ; it can be judged that when the running speed is close to 6.33m / s, the shoes with the shoe sole of Example 1 receive the reaction force of nearly 500N (near the maximum value) more than the shoes with ordinary shoe sole, and when the running speed is close to 4.7m / s, the shoes with the shoe sole of Example 1 receive the reaction force more than the shoes with ordinary shoe sole, and more than nearly 100N. Thus it can be judged that the shoe sole of Example 1 can effectively improve the rebounding capacity of the shoe sole, and the rebounding capacity is stronger with the increase of the running speed.

[0092] Test three:

[0093] Experimental content: the same volume and structure of the elastic cylindrical body in example 2 and example 3 were selected to prepare the same volume, structure of the elastic cylindrical body to impact test, the total weight of the impact weight was changed in turn as full weight (2000N), half weight (1200N) and zero weight (400N), the gravity gradient corresponded to high load, medium load and low load in turn, and the rebound ability rate corresponding to each load was recorded, as shown in table 2.

[0094] Table 2 energy rebound rate of elastic cylindrical body in impact test experiment under different loads.

[0095] Full weight (energy rebound rate) Half weight (energy rebound rate) Zero weight (energy rebound rate) Example 2 62.95％ 70.69％ 73.52％ Example 3 60.45％ 73.04％ 66.36％

[0096] Conclusion: according to table 2, it can be seen that example 2 without filling gas presents higher energy rebound under low load, and example 3 after filling gas presents higher energy rebound under medium load, so it can be judged that filling gas can change the size of energy rebound, and according to the size of load, the amount of filling gas can be adjusted to obtain the maximum energy rebound under the target load, and realize high energy rebound of the sole
