Description

TECHNICAL FIELD

[0001] The utility model relates to a walking shoe technical field, concretely relates to a dynamic cushioning sole. BACKGROUND

[0002] Walking shoes are designed and manufactured according to people's daily activities and work requirements, and their sole structure is different from traditional leisure shoes and sports shoes. This type of shoes combines moderate cushioning performance, can provide effective cushioning effect when moving, and has excellent support to reduce the pressure and fatigue of lower limbs caused by long-time walking or standing. Walking shoes are suitable for diversified wearing scenes due to their multifunctionality and applicability, and meet the high requirements of convenience and practicality of shoes in modern life. They not only provide comfort for daily wear, but also ensure applicability in various working environments, and are an ideal choice for daily life and work.

[0003] However, the existing walking shoes adopt homogeneous sole structure to realize overall cushioning of the sole. In order to consider that the stress of each area of the sole of the wearer is different in the dynamic process of walking, the existing walking shoes cannot meet the differentiated needs of each anatomical area of the sole for cushioning and support function when standing or walking, and the user needs to rely on the lower limb muscles to maintain balance, which increases the fatigue of the lower limbs. Especially when walking, the defect in the design of the existing walking shoes seriously reduces the dynamic cushioning effect of the foot during walking. SUMMARY

[0004] In view of the above problems in the prior art, the utility model provides a dynamic cushioning sole, which solves the problem of poor dynamic cushioning caused by the homogeneous sole structure of the existing walking shoes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dynamic cushioning sole is provided, which comprises a sole body, a dynamic cushioning structure with different density from the sole body is embedded on the bottom surface of the sole body, the dynamic cushioning structure comprises a first cushioning sheet located on the forefoot area and the lateral area of the midfoot of the sole body, and a second cushioning sheet located on the heel area of the sole body.

[0007] In this scheme, the double-density structure of the sole body and the dynamic cushioning structure improves the support and cushioning effect of the sole, and the positions of the first cushioning sheet and the second cushioning sheet are concentrated in the concentrated area of the load of the adult foot. The main load-bearing area of the sole of the user when walking and standing is accurately supported, the support effect is guaranteed, and good dynamic cushioning is achieved at the same time, which effectively reduces the fatigue of the lower limbs caused by long-time standing or walking, and has the functions of support, cushioning and anti-fatigue.

[0008] Further, by collecting information of the load concentration area of adult human foot, it is found that the load of adult human is mainly concentrated in the hallux area, the metatarsophalangeal area, the lateral midfoot area and the heel area. Therefore, the first cushioning sheet comprises a hallux part for supporting the hallux area on the forefoot area, a metatarsophalangeal part for supporting the metatarsophalangeal area on the forefoot area and a lateral midfoot part for supporting the lateral midfoot area.

[0009] Further, the bottom surface of the metatarsophalangeal part is projected as an inclined "∞" shape. The inclined upper end of the metatarsophalangeal part is fixed with the hallux part which is projected as a circular shape, and the inclined lower end of the metatarsophalangeal part is fixed with the lateral midfoot part. The metatarsophalangeal part projected as an "∞" shape can more naturally cover the metatarsophalangeal area, provide better flexibility and adaptability, and at the same time maintain the necessary support force.

[0010] Further, the second cushioning sheet is projected as a cam shape in an inclined manner. The second cushioning sheet can optimize the pressure distribution of the heel area.

[0011] Further, the bottom surface of the shoe sole body coincides with the bottom surface of the dynamic cushioning structure and is wavy. The wavy shape is a sine wave, a triangular wave or a trapezoidal wave along the walking direction, which improves the adaptability of the shoe sole to the natural gait of the human body and improves the gait efficiency.

[0012] Further, the bottom surface of the first cushioning sheet and the second cushioning sheet is provided with anti-skid lines. The anti-skid lines can be concentric circles, concentric triangles or concentric rhombus structures, which improve the anti-skid effect.

[0013] Further, the hardness of the shoe sole body and the dynamic cushioning structure is between 35C and 48C. The hardness range of 35C-48C provides good cushioning and rebounding effect, and the different hardness of the shoe sole body and the dynamic cushioning structure can bring better buffering effect.

[0014] Further, an X-shaped anti-torsion balance sheet is arranged in the arch area of the shoe sole body. The arrangement of the X-shaped anti-torsion balance sheet in the arch area strengthens the stability of the arch area, protects the arch, reduces the pulling pressure caused by long-time standing or walking, and prevents ankle injuries caused by excessive torsion.

[0015] Further, the X-shaped anti-torsion balance sheet is a nylon iron core sheet with a hardness of 77-83HD.

[0016] Further, the material of the shoe sole body and the dynamic cushioning structure is Pebax, TPU, TPEE or EVA. Pebax (polyether block amide), TPU (thermoplastic polyurethane elastomer rubber), TPEE (thermoplastic polyester elastomer) and EVA (ethylene-vinyl acetate copolymer) materials all have excellent physical properties, including high wear resistance, good elasticity and light weight characteristics.

[0017] The utility model discloses a dynamic cushion sole, and has the beneficial effects that:

[0018] 1. The double-density structure of the sole body and the dynamic cushion structure improves the support and cushioning effect of the sole, and the positions of the first cushioning sheet and the second cushioning sheet are concentrated in the concentrated area of the load of the foot of an adult, so that the main load-bearing area of the sole of the user during walking and standing is accurately supported, the dynamic cushioning nature is good while the support effect is ensured, the lower limb fatigue caused by long-time standing or walking is effectively reduced, and the sole has the functions of support, buffering and fatigue resistance.

[0019] 2. The utility model adopts the wavy bottom surface to improve the adaptability of the shoe to the natural gait of the human body and improve the gait efficiency. The anti-torsion balance sheet is implanted in the arch part of the sole to prevent ankle injury caused by excessive torsion of the shoe, the combination of the double-density structure, the wavy bottom surface and the X-shaped anti-torsion balance sheet effectively reduces the lower limb fatigue caused by long-time standing or walking, and significantly improves the wearing experience.

[0032] Reference Figure 5 And Figure 6 An X-shaped anti-torsion balance sheet 3 is arranged in the arch area in the sole body 1. In the embodiment, the X-shaped anti-torsion balance sheet 3 is a nylon iron core sheet with a hardness of 77-83HD. The X-shaped anti-torsion balance sheet 3 arranged in the arch area strengthens the stability of the arch area, protects the arch, reduces the pulling pressure caused by long-time standing or walking, and prevents ankle injuries caused by excessive torsion.

[0033] Reference Figure 2 As a specific structure of the dynamic cushioning structure 2, the dynamic cushioning structure 2 can comprise a plurality of plates, preferably, the dynamic cushioning structure 2 of the embodiment comprises a first cushioning sheet 21 arranged on the forefoot area and the lateral area of the midfoot of the sole body 1 and a second cushioning sheet 22 arranged on the heel area of the sole body 1.

[0034] The inventor collects information of the load concentration area of adult human foot and finds that the load of adult human is mainly concentrated in the hallux area, the metatarsophalangeal area, the lateral midfoot area and the heel area. The metatarsophalangeal area includes the first to fifth metatarsophalangeal areas on the shoe sole body 1. Referring to Figure 7 The color ranges from blue to red, indicating that the load of the area ranges from small to large. Therefore, the first cushioning sheet 21 of the embodiment includes a hallux part 211 for supporting the hallux area on the forefoot area, a metatarsophalangeal part 212 for supporting the metatarsophalangeal area on the forefoot area, and a lateral midfoot part 213 for supporting the lateral midfoot area.
