Description
一种减震结构 技术领域 Shock absorbing structure
本发明涉及鞋用减震结构， 尤其是鞋底用的软发泡材料的减震结构。 The present invention relates to a shock absorbing structure for shoes, and more particularly to a shock absorbing structure of a soft foamed material for a sole.
背景技术 Background technique
鞋子在人们日常穿着使用过程中， 鞋底要隔离和消除路面不平整对脚掌造 成的不适感， 同时还要保护脚掌在行走过程中不会被地面坚硬物体的刺伤。 尤 其在奔跑、 跳跃等剧烈运动时， 人体的脚弓、 脚踝和膝盖等关节部位都会承受 瞬间巨大的冲击， 如果不能有效的緩解和消除这些冲击对人体的伤害， 人体的 这些关节部位就很容易在运动中受伤。 随着科技的进步和人类认识的提高， 很 多新材料和新结构被用在鞋底中来实现鞋子的减震功能， 以减少人体在运动中 对关节和脚掌的损害， 尽量提高鞋子穿着的舒适性。 In the daily wearing and use of shoes, the soles should isolate and eliminate the discomfort caused by the unevenness of the road surface, and at the same time protect the soles of the feet from being stabbed by hard objects on the ground during walking. Especially in the strenuous exercise such as running, jumping, etc., the joint parts of the human body's arch, ankle and knee will bear a huge impact. If it can't effectively alleviate and eliminate the damage of these impacts on the human body, these joint parts of the human body are very easy. Injured in sports. With the advancement of technology and the improvement of human understanding, many new materials and new structures are used in the sole to achieve the shock absorption function of the shoes, so as to reduce the damage to the joints and soles of the human body during exercise, and to maximize the comfort of wearing the shoes. .
目前实现鞋类减震功能的做法主要有两类。 There are two main types of practices for achieving shock absorption in footwear.
一种是利用鞋底材料本身的性能减震。 通行的做法是用具备一定性能特征 的材料预制成减震垫并加载在鞋底合适的位置来实现减震效果， 例如发泡橡胶 垫， 硅胶垫， 发泡聚氨酯垫， 发泡 EVA垫等等。 这些发泡后的树脂材料内部有 蜂窝状的结构， 蜂窝状的孔洞内充满了空气。 在受到外力冲击时， 外力会挤压 发泡材料的外壁来压缩孔洞内的空气的体积并将空气排到大气中去， 这个过程 延緩了冲击力释放的时间和位移， 所以能起到緩冲减震的效果。 在冲击消失后， 孔洞内的气压低于周围的大气压， 空气会迅速回流并充斥发泡材料的孔洞， 当 空洞内和空气中的气压形成平衡后， 蜂窝状结构恢复原形， 如图 1 所示。 这种 材料减震方式使用的大都是树脂材料， 本身质地柔软， 脚掌接触感觉较为舒适， 所以利用材料减震在目前使用的较多。 但是因为各种树脂材料的性质造成的这 种蜂窝结构特点， 导致在冲击消失后， 发泡材料完全恢复原状的时间会较慢， 而且在连续冲击后， 蜂窝状结构也容易被损坏而损害发泡材料的恢复能力。 所 以材料减震的特点是接触柔软但反应迟钝， 而且减震垫的寿命不长， 使用一定 时间后， 减震垫会出现软榻的缺陷而失去减震能力。 One is to use the performance of the sole material itself to absorb shock. The prevailing practice is to pre-form the cushion with a material with certain performance characteristics and load it in a suitable position on the sole to achieve shock absorption effects, such as foam rubber mat, silicone mat, foamed polyurethane mat, foamed EVA mat, etc. . These foamed resin materials have a honeycomb structure inside, and the honeycomb holes are filled with air. When subjected to an external force, the external force will squeeze the outer wall of the foamed material to compress the volume of the air in the hole and discharge the air to the atmosphere. This process delays the release time and displacement of the impact force, so it can buffer Shock absorption effect. After the impact disappears, the air pressure in the hole is lower than the surrounding atmospheric pressure, and the air will quickly reflow and fill the pores of the foamed material. When the air pressure in the cavity is balanced with the air, the honeycomb structure returns to its original shape, as shown in Figure 1. . Most of the material damping methods use resin materials, which are soft in texture and comfortable to touch on the soles of the feet. Therefore, the use of material damping is currently used more. However, due to the nature of the various resin materials, the honeycomb structure is characterized by a slower recovery of the foamed material after the impact disappears, and the honeycomb structure is easily damaged and damaged after continuous impact. The ability to recover foam materials. Therefore, the shock absorption of the material is characterized by soft contact but unresponsiveness, and the life of the cushion is not long. After a certain period of time, the cushion will have the defect of the soft couch and lose the shock absorption capability.
另一种通常被称为结构减震， 是用树脂材料形成一个封闭的容腔， 并在空 腔内充装压力超过一个大气压的气体。 此种结构， 在容腔的腔壁受到外来冲击
时， 因容腔内气体不能外泄， 外力会导致容腔壁变形并压缩容腔内气体体积以 分解、 延緩冲击力， 从而实现緩冲和减震的功能。 在冲击消失后， 被压缩的气 体会迅速膨胀并恢复腔壁的形状。 这种结构减震方式因为是在封闭的容腔内预 先设置了高于大气压的气体， 所以在外力消失后容腔的恢复过程会非常迅速， 但是因为内置气压较高， 在冲击力不大的情况下， 像一个充满气的皮球脚掌与 容腔的接触会感觉较硬， 其舒适感比前述材料减震的方式要差。 而且， 一旦树 脂形成的腔壁受损漏气以后， 这种结构形成的减震能力就会完全丧失。 The other type, commonly referred to as structural shock absorption, is to form a closed cavity with a resin material and to fill the cavity with a gas having a pressure of more than one atmosphere. This structure is subject to external impact on the cavity wall of the cavity When the gas in the cavity cannot be leaked, the external force will cause the cavity wall to deform and compress the gas volume in the cavity to decompose and delay the buffering force, thereby realizing the function of buffering and damping. After the impact disappears, the compressed gas expands rapidly and restores the shape of the cavity wall. This type of structural damping method is because the gas above atmospheric pressure is preset in the closed cavity, so the recovery process of the cavity will be very rapid after the external force disappears, but because the built-in air pressure is high, the impact force is not large. In this case, the contact between the foot of the ball and the cavity of a gas-filled ball will feel harder, and the comfort is less than that of the aforementioned material. Moreover, once the cavity wall formed by the resin is damaged and leaked, the shock absorbing ability of such a structure is completely lost.

采用上述结构， 软发泡体被一柔性气密包裹层封闭包裹， 当软发泡体受到 外力作用时， 被封闭在发泡体内空洞中的气体由于不能流出柔性气密包裹层内 的发泡体， 而只能被压缩， 从而达到緩冲减震的效果。 当外力解除时， 在柔性

具体实施方式 detailed description
下面结合附图对本发明作进一步详述： The present invention will be further described in detail below with reference to the accompanying drawings:
见图 2、 图 3所示， 为本发明的一种柔性气密材料封闭包裹软质发泡材料的 减震结构的示意图。包括软发泡体 1 ,在该软发泡体 1外有一柔性气密包裹层 2 , 所述软发泡体 1被所述柔性气密包裹层 1封闭包裹， 该柔性气密包裹层 1覆着 在所述软发泡体 1 的外壁上， 可以使用胶水把所述柔性气密包裹层 2与软发泡 体 1粘接在一起，也可以是采用一定工艺将所述柔性气密包裹层 1与软发泡体 1 一体成型。 该柔性气密包裹层 2 为柔软的气密材料制作， 如此使得所述软发泡 体 1与外界大气隔离。 当软发泡体 1受到外力作用时， 见图 3所示， 软发泡体 1 分解吸收了外力， 微孔中的气体被挤压。 而柔性气密包裹层 1 实际上是一个弹 性的封闭气嚢， 当柔性气密包裹层 2 受到外力作用时， 亦会分解吸收外力。 此 时软发泡体 1和柔性气密包裹层 2 同时起到分解吸收外力的作用， 在这种构造 中充分利用了软发泡体 1 的柔软的材质特点， 封闭容腔内是常压气压， 而不存 在现有技术结构减震中预设压力导致的较为坚硬的外壁接触感。 所以此种结构 会在保持接触柔软的同时还可以保证緩冲减震的快速响应迅速分解及吸收冲击 力。 更有意义的是， 此种结构在实现緩冲减震的功能时， 蜂窝状微孔结构内的 气体不是被排出去而是被压缩， 所以蜂窝状微孔结构的构造在频繁的冲击过程 中， 材料变形不会很大， 材料不会很快疲劳而丧失恢复变形的能力， 从而大大 地延长了封闭腔壁内发泡材料的使用寿命。 当软发泡体 1 微孔结构中的气体在 柔性气密包裹层 2的作用下受到挤压时， 软发泡体 1微孔结构中的气体被压缩，
此时使得柔性气密包裹层 2 内成为一个内压大于大气压的气嚢。 当继续施加外 力时， 该施加的外力不但会受到所述软发泡体 1 形体变形所产生的发泡体反作 用力； 而且会受到所述柔性气密包裹层 2所形成的封闭气嚢所产生的反作用力， 也就是说被挤压出软发泡体 1 的气体会面对一个被柔性气密包裹层 2 阻挡回来 的气体所形成的反作用力。 两种反作用力叠加在一起， 使得本发明的一种柔性 气密材料封闭包裹软质发泡材料的减震结构材料有了较强的抗外压能力。 当外 力解除时， 在柔性气密包裹层 2 内高气压的作用下， 所述柔性气密包裹层 2 内 气体会迅速回到软发泡体 1 的微孔中。 如此， 从而使得本发明的一种柔性气密 材料封闭包裹软质发泡材料的减震结构材料能够达到回弹速度快， 复原效果好。 由于有柔性气密包裹层 2将软发泡体 1封闭包裹， 使得软发泡体 1避免了受到 外界水分、 微生物等侵害， 从而也可以延长软发泡体 1的使用寿命。 本发明人采用本发明与图 1所示现有技术进行对比试验。 As shown in FIG. 2 and FIG. 3, it is a schematic diagram of a shock absorbing structure in which a flexible airtight material encloses a soft foamed material according to the present invention. The soft foam body 1 is provided, and a flexible airtight wrap 2 is disposed outside the soft foam body 1. The soft foam body 1 is enclosed and wrapped by the flexible airtight wrap layer 1, and the flexible airtight wrap layer 1 is covered. On the outer wall of the soft foam body 1, the flexible airtight wrap layer 2 may be bonded to the soft foam body 1 by using glue, or the flexible airtight wrap layer may be coated by a certain process. 1 is integrally molded with the soft foam 1. The flexible airtight wrap 2 is made of a soft airtight material such that the soft foam 1 is isolated from the outside atmosphere. When the soft foam 1 is subjected to an external force, as shown in Fig. 3, the soft foam 1 decomposes and absorbs an external force, and the gas in the micropores is pressed. The flexible airtight wrap 1 is actually an elastic closed air squeezing. When the flexible airtight wrap 2 is subjected to an external force, it also decomposes and absorbs external force. At this time, the soft foam body 1 and the flexible airtight wrap layer 2 simultaneously function to decompose and absorb external force, and in this structure, the soft material characteristics of the soft foam body 1 are fully utilized, and the closed cavity is a normal pressure air pressure. There is no relatively stiff outer wall contact feeling caused by the preset pressure in the prior art structure damping. Therefore, this structure can ensure the rapid response of the shock absorption and the rapid response of the shock absorption and shock absorption while maintaining the soft contact. What is more significant is that when the structure realizes the function of buffer damping, the gas in the honeycomb microporous structure is not discharged but compressed, so the structure of the honeycomb microporous structure is in the process of frequent impact. The material deformation is not very large, the material does not fatigue quickly and loses the ability to recover deformation, thereby greatly prolonging the service life of the foamed material in the closed cavity wall. When the gas in the microcellular structure of the soft foam 1 is pressed by the flexible airtight coating layer 2, the gas in the microporous structure of the soft foam 1 is compressed. At this time, the inside of the flexible airtight wrapping layer 2 is made into a gas cylinder having an internal pressure greater than atmospheric pressure. When the external force is continuously applied, the applied external force is not only caused by the foam reaction force generated by the deformation of the soft foam body 1 but also by the closed air enthalpy formed by the flexible airtight coating layer 2. The reaction force, that is, the gas that is squeezed out of the soft foam 1 faces a reaction force formed by a gas blocked by the flexible airtight wrap 2 . The two reaction forces are superimposed, so that the flexible gas-tight material of the present invention encloses the shock-absorbing structural material of the soft foamed material to have a strong external pressure resistance. When the external force is released, the gas in the flexible airtight encapsulation layer 2 quickly returns to the micropores of the soft foam body 1 under the action of the high air pressure in the flexible airtight encapsulation layer 2. In this way, a flexible airtight material of the present invention encloses the shock absorbing structural material of the soft foaming material to achieve a fast rebound speed and a good recovery effect. Since the flexible airtight wrap 2 encloses the soft foam 1 so that the soft foam 1 is protected from external moisture, microorganisms, etc., the service life of the soft foam 1 can be prolonged. The inventors conducted a comparative test using the present invention and the prior art shown in Fig. 1.
