Description

Technical Field

[0001] This utility model relates to the field of shoe soles, and in particular to a shoe sole with balanced shock absorption. Background Technology

[0002] Sports shoes are shoes designed and manufactured based on the characteristics of people participating in sports or travel. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. They are generally soft and elastic, which can provide a certain cushioning effect. They can enhance elasticity during exercise, and some can even prevent ankle injuries. The sole structure of sports shoes is quite complex and can include all the materials that make up the bottom, such as the outsole, midsole, and heel. Existing athletic shoe soles incorporate carbon plates inside the midsole to enhance elasticity. However, these soles have the following drawbacks: the carbon plates are all flat structures, lying straight below the arch, which cannot perfectly conform to all arch shapes. Furthermore, when the carbon plate bends, it relies primarily on overall bending, failing to effectively concentrate and amplify the energy generated by the metatarsophalangeal joint, thus reducing the overall propulsion efficiency of the sole. Additionally, the stress generated during bending tends to concentrate at both ends of the flat carbon plate, increasing the risk of breakage. Utility Model Content

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a shoe sole with balanced shock absorption.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a shoe sole with balanced shock absorption, comprising a midsole composed of an upper midsole layer, a support plate, and a lower midsole layer, wherein the upper midsole layer is located above the lower midsole layer and the two are fixedly connected, and a groove is provided at the connection between the upper midsole layer and the lower midsole layer, wherein the support plate is installed at the groove.

[0005] Preferably, the support plate has a hollowed-out groove in the middle.

[0006] In a further preferred embodiment, a groove is provided at the contact end between the bottom surface of the upper layer of the midsole and the upper surface of the support plate.

[0007] In a further preferred embodiment, three grooves are provided, and they are arranged in an arc shape, with the three grooves installed adjacent to each other at intervals.

[0008] In a further preferred embodiment, a groove is provided at the contact end between the upper surface of the middle bottom layer and the lower surface of the support plate.

[0009] In a further preferred embodiment, three grooves are provided, and they are arranged in an arc shape, with the three grooves installed adjacent to each other at intervals.

[0010] In a further preferred embodiment, a positioning block is provided in the middle of the upper surface of the bottom layer, and the positioning block is engaged with the hollow groove in the middle of the support plate.

[0011] In a further preferred embodiment, the groove is provided with a plurality of vent holes. In a further preferred embodiment, the bottom of the lower layer is also connected to a larger sole.

[0012] The beneficial effects of this utility model are: This invention features a support plate with a wave-shaped side and an overall arch shape. The arched curvature of the wave-shaped support plate better conforms to the natural curve of the foot arch and the curvature of the forefoot metatarsal bones, resulting in better foot feel, fit, and support. Furthermore, the support plate has an X-shaped structure when viewed from above. The four corners of the X-shaped support plate are distributed at the four corners of the midsole, providing four-corner support to the midsole and improving the overall balance and shock absorption of the sole.

[0013] This invention provides stable support between the upper layer of the midsole, the support plate, and the lower layer of the midsole through groove one and groove two. This creates multiple stable wave-shaped hollow structures between the upper and lower layers of the midsole and the wave-shaped support plate. These multiple wave-shaped hollow structures allow the wave-shaped bends of the support plate to be suspended without constraint. When the athlete pushes off the ground, the shape of the support plate changes freely, storing more elastic potential energy, thereby improving the shock absorption effect of the sole.

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments. Example 1

[0017] Please see Figure 1-3This utility model provides a shoe sole with balanced shock absorption, including a midsole 1 composed of an upper midsole 11, a support plate 12 and a lower midsole 13. The upper midsole 11 is located above the lower midsole 13 and the two are fixedly connected. A groove is provided at the connection between the upper midsole 11 and the lower midsole 13, and the support plate 12 is installed in the groove.

[0018] The support plate 12 has a hollow groove 121 in the middle, and the hollow groove 121 has an elliptical structure.

[0019] A groove 111 is provided at the contact end between the bottom surface of the upper layer 11 and the upper surface of the support plate 12.

[0020] There are three grooves 111, which are in an arc shape and are installed adjacent to each other.

[0021] A groove 131 is provided at the contact end between the upper surface of the middle bottom layer 13 and the lower surface of the support plate 12.

[0022] There are three grooves 2 131, which are in an arc shape and are installed adjacent to each other at intervals.

[0023] In this embodiment, the upper midsole layer 11 and the lower midsole layer 13 are connected by hot melt or glue; The side of the support plate 12 has a wave-shaped structure and is bow-shaped overall. The bow-shaped curvature of the wave-shaped support plate 12 better conforms to the natural curve of the arch of the foot and the curvature of the forefoot metatarsal bones, bringing better foot feel and support. Groove 111 and Groove 231 provide stable support between the upper midsole layer 11, the support plate 12 and the lower midsole layer 13, so that the upper midsole layer 11 and the lower midsole layer 13 and the wave-shaped support plate 12 form multiple stable wave-shaped hollow structures. Through multiple wave-shaped hollow structures, the wave-shaped bending part of the support plate 12 is suspended and unrestrained. When the athlete pushes off the ground, the support plate 12 changes shape freely and stores more elastic potential energy, thereby improving the shock absorption effect of the sole. The support plate 12 is made of titanium alloy, which has high strength and density and can withstand high-intensity impacts. The support plate 12 can also be made of nickel alloy, which has super elasticity and shape memory effect, improving the shock absorption effect of the midsole 1. Example 2

[0024] Please see Figure 1 and Figure 3 This utility model provides a shoe sole with balanced shock absorption. A positioning block 132 is also provided in the middle of the upper surface of the lower midsole layer 13. The positioning block 132 is engaged with the hollow groove 121 in the middle of the support plate 12. Multiple ventilation holes are provided inside the groove 111; The bottom of the middle and lower layer 13 is also connected to the outer sole 2.

[0025] In this embodiment, the top view of the support plate 12 is an X-shaped structure. The four corners of the X-shaped support plate 12 are distributed in the four corners of the inside of the midsole 1, providing four-corner support force for the midsole 1, improving the overall balance and shock absorption effect of the sole. In addition, the hollow groove 121 design of the support plate 12 reduces the overall weight of the support plate 12, making the support plate 12 lighter. The engagement and fixation of the hollow groove 121 with the positioning block 132 improves the positioning stability of the support plate 12 after it is installed on the upper surface of the middle bottom layer 13; The groove 111 has multiple ventilation holes to allow the feet to breathe.
