Description

一种用于鞋底的支撑结构及其鞋底和运动鞋 技术领域
本实用新型涉及运动鞋技术领域，具体为一种鞋底支撑结构及其鞋底。
 背景技术
为了获得最佳的弹跳高度和移动速度，人体会充分募集运动单位来提高下肢做功能力。研究人员为避免触地时的高冲击负荷，将鞋中底更换为减震材料。减震材料虽然能提供良好的保护作用，但同时面临着支撑与能量回归不足的缺点。现有技术中，通常会在较小牺牲缓冲性能的前提下增加中底弯折刚度，以此提高运动过程中的支撑性与能量回归。
足部作为人体与地面接触的末端环节，在纵跳过程中发挥了重要作用。而作为足第二大关节的跖趾关节，在该过程中处于完全吸能的背屈状态。因此，将跖趾关节所吸收的能量转移到鞋结构中储存起来，并在蹬伸阶段转化为人体动能，成为提高纵跳表现的一种有效方式。目前行业内鞋产品无法同时满足跖趾关节能量转移、跖趾关节良好屈曲以及触地时能量吸收这三种功能。
 技术问题
本实用新型的目的在于提供鞋底支撑结构及其鞋底，以实现鞋底能量回归性能，提升运动效果。
 技术解决方案
为实现上述目的，本实用新型采用以下技术方案：
本实用新型公开了一种用于鞋底的支撑结构，包括具有弹性的支撑片，所述支撑片设置于鞋底的前脚掌或者足弓位置，且其沿鞋底宽度方向布设，所述支撑片沿鞋底宽度方向设置有若干凸起弧形段或/和下凹弧形段。
进一步的，所述支撑片的材料为碳纤维板或者TPU板，其硬度≤0.261Nm/deg。
其中，所述支撑片沿鞋底的宽度方向的两侧为凸起弧形段，中间为平面；或者内侧为凸起弧形段，中部及外侧为平面；或者整体为一个凸起弧形段，或者中部为凸起弧形段，两侧为平面。
其中，所述支撑片沿鞋底的宽度方向的中部为下凹弧形段，两侧为平面。
其中，所述支撑片包括两片，两片支撑片分布于足跖趾关节连线两侧。
优选的，还包括位于支撑片上表面或者下表面的支撑板，所述支撑板与支撑片连接。
另一实施方式中，还包括位于支撑片下方的支撑板，所述支撑板沿鞋底长度方向布设，所述支撑板与支撑片之间填充弹性材料。
优选的，所述支撑片的上表面向下的弯折度为a，下表面向上的弯折度为b，则a＞b。
本实用新型还公开了一种鞋底，包括上述支撑结构，其粘结或一体成型于鞋中底上表面，或者粘结或一体成型于鞋中底与鞋外底之间，或者内嵌于鞋中底内部。
优选的，所述支撑结构置于鞋中底上表面，所述鞋中底上设置有与凸起弧形段位置相对应的底凸，或者所述鞋中底上设置与下凹弧形段位置相对应的凹槽。
进一步的，所述底凸或者凹槽部位的材料为高回弹性EVA材料，其回弹率为55-70%。
本实用新型还公开了一种运动鞋，包括上述的鞋底。
 有益效果
由于采用了上述结构，本实用新型具有以下有益效果：
1、本实用新型能够将触地和缓冲阶段的人体动能转化为鞋底支撑结构的弹性势能，并在蹬伸阶段再次将弹性势能转化为人体动能，从而有利于弹跳，提升运动效果。
2、支撑片的材料选用碳纤维板或者TPU板，使得其具有较好的弹性弯折性能。
3、本实用新型的支撑片上表面向下弯折度大于下表面向上的弯折度，使得更易向下弯折，有利于吸收冲击力，加大减震与能量回馈的效果。

 本发明的最佳实施方式
为了使本领域的技术人员更好地理解本实用新型的技术方案，下面结合附图和具体实施例对本实用新型作进一步详细的描述。
实施例一
如图1所示，本实施例公开了一种用于鞋底的支撑结构，包括具有弹性的支撑片1，支撑片1设置于鞋底的前脚掌位置（图1中Q处）或者足弓位置（图1中Z处），或者同时设置于前脚掌和足弓位置处，且其沿鞋底宽度方向（图1中X方向）布设。
本实施例中支撑片1沿鞋底宽度方向设置有若干受力可发生弹性形变的凸起弧形段2。
凸起弧形段2的数量可设置一个或多个。如图2中，支撑片1沿鞋底的宽度方向的两侧为凸起弧形段2，中间为平面3。图3中，支撑片1沿鞋底的宽度方向内侧为凸起弧形段2，中部及外侧为平面3。当鞋为左脚鞋时，鞋底的宽度方向内侧为右侧，当鞋为右脚鞋时，鞋底的宽度方向内侧为左侧。图4中支撑片1沿鞋底的宽度方向的整体为一个凸起弧形段2。图5中支撑片1沿鞋底的宽度方向的中部为凸起弧形段2，两侧为平面3。
支撑片1可以包括一片或两片。如图6所示，两片支撑片1分布于足跖趾关节连线g的两侧，不会影响到跖趾关节处的弯折刚度。
支撑片1的材料为碳纤维板或者TPU板。碳纤维板的硬度有不同种类，为了使本申请的碳纤维板的弹性较好，采用碳纤维的硬度≤0.261Nm/deg。碳纤维板材料对力的感受更加敏感，同时对形变的响应速度更快。因此使用该材料可以有效解决现有材料、结构能量回归速率慢，以至于起跳动作已完成，但所吸收的能量并未充分释放的问题。
 本发明的实施方式
实施例二
本实施例公开了一种用于鞋底的支撑结构，包括具有弹性的支撑片1，支撑片1设置于鞋底的前脚掌位置，且其沿鞋底宽度方向布设，其沿鞋底宽度方向设置有若干受力可发生弹性形变的下凹弧形段4。
如图7、8所示，本实施例中支撑片1沿鞋底的宽度方向的中部为下凹弧形段4，两侧为平面3。
实施例三
如图9所示，本实施例公开了一种用于鞋底的支撑结构，包括若干具有弹性的支撑片1以及固定于支撑片1下表面或上表面的支撑板5。图10中支撑板5固定于支撑片1下表面。图11中支撑板5固定于支撑片1的上表面，支撑板5的设置使得在运动踩踏时稳定性更好。
实施例四
如图12所示，本实施例公开了一种用于鞋底的支撑结构，包括具有弹性的支撑片1以及位于支撑片1下方的支撑板5，支撑板5的硬度大于支撑片1的硬度。支撑板5沿鞋底长度方向布设，支撑板5与支撑片1之间填充鞋底材料（如EVA材料）。填充EVA材料，以保持结构在工作过程中的稳定状态，同时进行二次缓冲与能量回归。
实施例五
本实施例公开了一种鞋底，包括实施例一的支撑结构。鞋底支撑结构粘结或一体成于鞋中底6上表面。
如图13所示，支撑片1与鞋中底6间为镂空的空间。支撑片1为碳纤维板，碳纤维板的两面的弯折度不同，上表面向下的弯折度为a，下表面向上的弯折度为b，则a＞b。即将碳纤维板按正确的方向进行安装，使得碳纤维板更易向下弯折，有利于吸收冲击力，加大减震与能量回馈的效果。
如图13、14所示，在跖趾关节跖屈时，支撑片受力F发生弯折，能量储存于支撑片1上，此时具有较大的形变复原趋势(回弹力F')，利于将支撑片1中的能量释放。同时，跖趾关节做跖屈动作时收到阻力更小，良好的跖屈可以为踝关节提供稳定的工作环境，利于提高纵跳表现。
实施例六
本实施例公开了一种鞋底，包括实施例一的支撑结构。支撑片1沿向下弯折度大于向上的弯折度的方向粘结或一体成型于鞋中底上方，或者粘结或一体成于鞋中底与鞋外底之间，或者内嵌于鞋中底内部。
如图15所示，鞋中底6上设置有与支撑片1的凸起弧形段位置相对应的底凸7。支撑片1的凸起弧形段由底凸7贴合支撑。底凸7为EVA材料制成，其回弹率为55-70%，即底凸为一种高回弹性EVA材料，高回弹性的底凸可便于支撑片发生弹性形变。
实施例七
本实施例公开了一种鞋底，包括实施例二的支撑结构。支撑结构粘结或一体成于鞋中底上表面，或者粘结或一体成于鞋中底与鞋外底之间，或者内嵌于鞋中底内部。
如图7、8所示，鞋中底6上设置有与支撑片1的下凹弧形段位置相对应的凹槽8。凹槽部位的鞋中底选为高回弹性的EVA材料制成，其回弹率为55-70%。
实施例八
本实施例公开了一种鞋底，包括实施例三或实施例四的支撑结构。
如图16所示，支撑板5沿鞋底长度方向布设，支撑片1设置两片沿鞋底宽度方向布设，支撑片1位于支撑板5上，支撑板5与支撑片1之间为镂空（图10所示），或者支撑板5与支撑片1之间填充鞋底材料（图12所示），如高回弹性的EVA材料，其回弹率为55-70%。
实施例九
本实施例公开了一种运动鞋，包括实施例五至实施例八中任一种的鞋底。
 工业实用性
以上所述，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本实用新型的保护范围之内。
