Description

一种减少损伤的运动鞋底
技术领域
本发明涉及体育用品领域，具体涉及一种减少损伤的运动鞋底。
背景技术
在步行或慢跑的过程中，脚后跟往往首先落地，承受了最大的压力。脚后跟受到冲击时容易造成各种运动损伤。虽然现有各种运动鞋中，采用多层弹性的设置减少了对脚后跟的力学冲击，但是效果差，对冲击的缓冲效果不够好。
发明内容
为解决以上问题，本发明提供了一种减少损伤的运动鞋底，包括鞋大底、鞋中底弹性本体、填腹弹性本体；鞋中底弹性本体设置在鞋大底的顶面上，填腹弹性本体设置在鞋中底弹性本体上；鞋大底的顶面上设有凹坑。
更进一步地，鞋大底的底面设有防滑纹。
更进一步地，防滑纹的材料为橡胶。
更进一步地，鞋大底的材料为EVA材料。
更进一步地，鞋中底弹性本体的材料为EVA材料。
更进一步地，填腹弹性本体的材料为EVA材料。
更进一步地，鞋大底的硬度大于鞋中底弹性本体的硬度。
更进一步地，填腹弹性本体的硬度大于鞋中底弹性本体的硬度。
更进一步地，凹坑的形状为圆形或方形。
更进一步地，凹坑的顶部宽、底部窄。
本发明的有益效果：本发明提供了一种减少损伤的运动鞋底，包括鞋大底、鞋中底弹性本体、填腹弹性本体；鞋中底弹性本体设置在鞋大底的顶面上，填腹弹性本体设置在鞋中底弹性本体上；鞋大底的顶面上设有凹坑。当鞋底受到冲击时，鞋中底弹性本体压迫鞋大底，部分鞋中底弹性本体进入凹坑，本发明一方面利用鞋大底、鞋中底弹性本体、填腹弹性本体的弹性缓冲冲击；另一方面应用凹坑中的气体缓冲冲击。所以本发明更优地吸收运动过程中的有害冲击，减少运动过程中的运动损伤。
以下将结合附图对本发明做进一步详细说明。

图2是又一种减少损伤的运动鞋底的示意图。
图中：1、鞋大底；2、鞋中底弹性本体；3、填腹弹性本体；4、凹坑。
具体实施方式
为使本申请的目的、技术方案及优点更加清楚明白，以下参照附图并举实施例，对本申请作进一步详细说明。
实施例1
本发明提供了一种减少损伤的运动鞋底，包括鞋大底1、鞋中底弹性本体2、填腹弹性本体3。图1是本发明运动鞋底的结构示意图。鞋中底弹性本体2设置在鞋大底1的顶面上，填腹弹性本体3设置在鞋中底弹性本体2上。填腹弹性本体3为轻质弹性材料。鞋大底1的顶面上设有凹坑4。凹坑4的形状为圆形或方形。优选地，凹坑4的形状为圆形。鞋大底1的底面设有防滑纹。防滑纹的形状为两种以上，以便于防止不同方向的滑动。防滑纹的材料为耐磨橡胶或橡胶玻璃纤维。鞋大底1、鞋中底弹性本体2、填腹弹性本体3的材料均为EVA材料。
当鞋底受到冲击时，鞋中底弹性本体2压迫鞋大底1，部分鞋中底弹性本体2材料进入凹坑4，本发明一方面利用鞋大底1、鞋中底弹性本体2、填腹弹性本体3本身的弹性缓冲冲击；另一方面应用凹坑4中的气体缓冲冲击。所以本发明更优地吸收运动过程中的有害冲击，减少运动过程中的运动损伤。
EVA是乙烯和醋酸共聚而成的，中文化学名称为乙烯-醋酸乙烯共聚物。与聚乙烯相比，EVA由于在分子链中引入醋酸乙烯单体，从而降低了高结晶度，提高了韧性、抗冲击性、填料相容性、化学耐腐蚀性和热密封性。在本发明中引入EVA材料有助于大幅度提升鞋底的抗冲击能力。
鞋大底1的硬度大于鞋中底弹性本体2的硬度，填腹弹性本体3的硬度大于鞋中底弹性本体2的硬度。它们三个的硬度从高到低依次为：鞋大底1、填腹弹性本体3、鞋中底弹性本体2。鞋大底1的硬度在48度附近，填腹弹性本体3的硬度在38度附近，鞋中底弹性本体2的硬度在32度附近。这样一来，不仅能够对冲击具有较好的缓冲能力，而且脚不易感受到鞋底的瘫软。
另外，本发明不仅采用凹坑4中的空气进行缓冲冲击，凹坑4还减少了鞋底的质量，使得鞋底更轻便。
另外，当鞋中底弹性本体2受到压力时，鞋中底弹性本体2部分地进入凹坑4，也就是说，鞋中底弹性本体2的材料进入到凹坑4内，从而导致鞋中底弹性本体2与鞋大底1更紧密的结合，鞋中底弹性本体2不易相对于鞋大底1产生滑动。
实施例2
在实施例1的基础上，如图2所示，鞋中底弹性本体2的底面设有突出部，突出部位于凹坑4上方。突出部的尺寸大于或等于凹坑4顶部的尺寸。这样一来，当受到冲击或压力时，鞋中底弹性本体2更多地进入到凹坑4内，对凹坑4内的气体造成更好的封堵，一方面提升了鞋底的缓冲冲击能力，另一方面鞋中底弹性本体2相对于鞋大底1更不易产生移动。
实施例3
在实施例2的基础上，凹坑4的顶部宽、底部窄。具体地，凹坑4的形状为圆柱形，凹坑4顶部的尺寸大，凹坑4底部的尺寸小。这样一来，在鞋中底弹性本体2受到压力时，鞋中底弹性本体2更容易进入凹坑，并且对凹坑4内气体压力改变更多，从而实现更优的缓冲冲击效果。
实施例4
在实施例3的基础上，在脚后跟的中部，凹坑4密；在脚后跟的边缘，凹坑4疏。这样一来，当受到冲击时，脚后跟的中部形变更多，更多的鞋中底弹性本体2材料进入凹坑4，鞋底结构更稳定，对脚来说，也更平稳。
实施例5
在实施例4的基础上，相邻凹坑4之间设有通孔，相邻凹坑4的尺寸或深度不同。通孔贯穿相邻的凹坑4。也就是说，通孔连通相邻的凹坑4。当鞋底受到冲击时，由于相邻凹坑4内的气压不同，从而在相邻凹坑4之间的通孔中形成气流，该气流延缓了凹坑4内气体到达平衡状态的时间，也就是增加了鞋底承受冲击的时间，从而减小了冲击力，提高了鞋底的安全性，当运动员突然受到冲击时，不易受到运动损伤。
更进一步地，通孔倾斜设置，这样一来，受到冲击时，通孔两端、相邻凹坑4中更容易形成压强差，更容易在通孔中形成气流，延缓了凹坑4中的气压达到平衡的时间，更多地减小了冲击力，提高了鞋底的安全性。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
