Description

一种双向辨识的轮胎及轮胎模具 技术领域
本发明涉及一种双向辨识的轮胎及轮胎模具。
背景技术
随着轮胎行业的发展，生产工艺手段的不断进步，消费水平的不断提高，消费者对轮胎的要求也不仅仅停留在安全与舒适度上，对其外观的区别化或个性化的需求也有了更高的要求。因此现阶段在胎侧纹理设计上也越来越倾向于复杂化，多样化与高精度化，来满足消费者日益增长的需求。
但是，目前的轮胎外观上的区别一般采用纹理或凹凸图案形式的方式来区别，使得使用者知道轮胎的生产厂商、批号等信息，但是这种方式存在较大的缺陷。例如，比较容易仿制，会出现假冒轮胎，造成安全隐患，同时也会损害生产厂商的利益；而很多生产厂商为了避免假冒行为，不得不增加生产工序，加大外观区别性的相关生产步骤，又会增大轮胎质量控制的难度，增加生产成本。
同时，现有的轮胎外观单一，且只能展现出轮胎单一标识或字体，无法凸显轮胎的档次。
发明内容
本发明为了解决上述问题，提出了一种双向辨识的轮胎及轮胎模具，本发明可以在同一区域的不同视角，显示出不同图案、纹理或文字，能够有效防止 假冒轮胎的出现，同时对轮胎本身的性能不产生影响，不增加较多成本。
为了实现上述目的，本发明采用如下技术方案：
一种双向辨识的轮胎，轮胎胎侧处设置若干组具有多个并排设置的条状结构，其中，若干条状结构的第一侧壁具有第一反射变化部，所述第一反射变化部与条状结构的其他位置处反射角度不同，使得条状结构于第一视角可视第一图像；
同一组或/和其他组的若干条状结构的第二侧壁具有第二反射变化部，所述第二反射变化部与条状结构的其他位置处反射角度不同，使得条状结构于第二视角可视第二图像，实现双向辨识。
其中，第一反射变化部和第二反射变化部中的至少一个为对第一侧壁(或第二侧壁)进行加工而形成的倒角。
作为一种实施方式，可以是轮胎胎侧的同一处设置有多个条状结构，条状结构的两个侧壁的设置方式不同，因此在第一视角和第二视角呈现的图像不同(也可以相同)，实现双向辨识。
作为另一种实施方式，可以是在轮胎胎侧的不同位置设置至少两组条状结构，两组条状结构的图像不同(也可以相同)，视角不同，形成双向辨识。
进一步的，每个条状结构高度0.1～5mm之间，宽度0.1～5mm，相邻的条状结构之间的间距0.1～5mm。
进一步的，相邻的条状结构之间的间距相同。
当然，作为其他实施方案，条状结构之间的间距也可以不同，如形成间距渐变的形式，逐渐增大或逐渐减小，或者若干连续的条状结构之间间距相同，再连续若干条状结构之间间距相同，但两部分的相邻的条状结构之间间距彼此 不同等多种方式。
进一步的，每组的每个条状结构的长度相同。此处的长度是指条状结构较长的部分的长度。
当然，作为其他实施方案，条状结构的长度也可以不同，如形成渐变的形式，逐渐增大或逐渐减小，或者若干连续的条状结构的长度相同，再连续若干条状结构的长度也相同，但两组条状结构的长度彼此不同。
进一步的，每组的每个条状结构的宽度相同。
当然，作为其他实施方案，条状结构的宽度也可以不同，如形成渐变的形式，逐渐增大或逐渐减小，或者若干连续的条状结构的宽度相同，再连续若干条状结构的宽度也相同，但两部分的条状结构的宽度彼此不同。
进一步的，每个条状结构的宽度从第一端部到第二端部一致。即每个条状结构为等宽结构。
当然，作为其他实施方案，单个的条状结构的宽度也可以不同，如形成渐变的形式，逐渐增大或逐渐减小，如三角状或者梯形等。或者为梭型、菱形等形状。
进一步的，每个条状结构的形状相同。
当然，作为其他实施方案，条状结构的形状也可以不同，如条状结构呈三角状或者梯形，相邻的条状结构的朝向不同，交错着排列。或连续若干条状结构为一种形状，再连续若干的条状结构为另一种形状。
进一步的，相邻的条状结构之间具有一定的夹角。
作为一种优选的方式，若干组的条状结构呈扇形向心排列。
当然，在其他实施方式中，一组条状结构形成曲线型延伸。
进一步的，所述第一侧壁的第一反射变化部和第二侧壁的第二反射变化部的结构可以相同，也可以不同。
进一步的，所述第一侧壁的第一反射变化部和第二侧壁的第二反射变化部的结构可以为一个，也可为多个，且位于同一侧壁的反射变化部彼此之间的结构也可以不同。
进一步的，所述倒角的面为平面，平面和条状结构垂直方向的角度为10‐80度。优选为30‐60度。
作为另外一种实施方式，所述倒角的面为弧面，弧面为凸起的弧面或凹陷的弧面。弧面的覆盖的范围优选为条状结构宽度的1/2‐1/5。
作为一种实施方式，第一反射变化部和/或第二反射变化部的外表面整体的高度低于条状结构的上顶面。
作为一种实施方式，第一反射变化部和/或第二反射变化部采用激光雕刻而成。对于条状结构的加工效率高，且表面光洁度较好。激光加工后可以对加工后的表面进行表面处理，以增加表面光洁度，增加光线反射效果。
更为优选的方案，可以采用喷砂处理等去除表层的方式进行处理，以去除表面的激光高温氧化层。
更为优选的另一种方案，采用激光抛光的方式对条状结构的第一侧壁或第二侧壁进行处理，抛光效果好，而且雕刻完毕后，直接进行抛光，处理效率高。
进一步的，反射变化部的外表面上加工有任意形状，以增加光线的吸收效果或反射效果。
如，加工的形状可以为加工成波浪或尖锐的形状等。
进一步的，所述第一图像与第二图像内容不同。
一种轮胎模具，模具腔内与轮胎胎侧相对应的位置处的结构的形状与上述条状结构的形状互补。
即：具有多个并排设置的槽状结构，其中，若干槽状结构的第一侧壁具有第一反射变化部；
同一组或/和其他组的若干槽状结构的第二侧壁具有第二反射变化部；
使得生产的轮胎能够于第一视角可视第一图像，于第二视角可视第二图像，实现双向辨识。
较佳地，可在反射变化部上设置凸起部或条纹，以设定该反射变化部处对光的吸收率或反射率。其中，相邻的两个凸起部或条纹之间的间距可以在0.01～0.5mm的范围之内选择。
凸起部或条纹的平均宽度的范围可在0.04‐0.6mm之间，平均高度H至少为0.1mm。
凸起部或条纹的平均截面积可设置为7x10 ‐4‐0.2mm 2。
在具体为凸起部的情况中，每平方毫米的凸起部的数量至少为6个，平均高度至少为0.1mm。
与现有技术相比，本发明的有益效果为：
1)本发明丰富了对于轮胎胎侧纹理的设计方案，能更好的满足胎侧纹理的多样化以及个性化的需求，同时能够更好的杜绝假冒轮胎的出现；
2)两个视角方向看到的图案、文字或标识等不相同，利用简单的结构就能够实现双向辨识，增加了轮胎的辨识性；
3)本结构可以采用激光雕刻的加工工艺方法，加工效率高，表面成型质量高。尤其是类似倒角的结构，采用激光雕刻加工，加工效率更高。
4)反射变化部的外表面基本正对视线方向，能够起到非常好反射或漫反射效果，第一视角和第二视角方向的看到的视觉效果更加明显。

在本实施方式中，每个条状结构的宽度相同。
当然，作为其他实施方案，每个条状结构的宽度也可以不同，如形成渐变的形式，逐渐增大或逐渐减小，或者若干连续的条状结构的宽度相同，再连续若干条状结构的宽度也相同，但两组条状结构的宽度彼此不同。
在本实施例中，每个条状结构1的宽度从第一端部到第二端部一致。即每个条状结构为等宽的。
当然，作为其他实施方案，单个的条状结构的宽度也可以不同，如形成渐变的形式，逐渐增大或逐渐减小，如三角状或者梯形(如图10所示，为梯形， 且交错着排列)等。或者为梭型、菱形等形状。
每个条状结构高度0.1～5mm之间，每个条状结构宽度0.1～5mm，相邻的条状结构间距0.1～5mm。
相邻的条状结构之间具有一定的夹角。整组的条状结构还可以呈扇形向心排列(也就是说整组的条状结构的间距是从靠近圆心最近端到最远端是由小到大渐变的)。
当然，在其他实施方式中，整组条状结构形成曲线型延伸。
进一步的，如图3(a)‐图3(i)和图4(a)‐(i)所示，轮胎的第一侧壁的反射变化部和第二侧壁的反射变化部的结构可以相同，也可以不同。
也就是说，第一侧壁的反射变化部的结构可以选择如图3(a)‐图3(f)中的任一种，或为其他类型。而第二侧壁的反射变化部的结构可以如图4(a)‐图4(f)中的任一种，或为其他类型。
作为一种优选方式，反射变化部为缺口，缺口为倒角，倒角的面为平面，平面和条状结构垂直方向的角度为10‐80度。优选为30‐60度。
作为另外一种实施方式，倒角的面为弧面，弧面为凸起的弧面或凹陷的弧面。弧面的覆盖的范围优选为条状结构宽度的1/2‐1/5。
作为进一步的优选方式，为倒角的反射变化部呈平面，且在该平面上设有多个凸起部或条纹，如图3(d)、4(d)、5(d)、6(d)中所示的。这些凸起部或条纹可以进一步影响反射变化部处对光线的吸收率或反射率。可对反射变化部上凸起部或条纹的高度、平均截面积或宽度、以及相邻的凸起部或条纹之间的间隔进行选择，以获得所需要的吸收效果或反射效果。例如，对应于条状结构的尺寸，相邻的两个凸起部或条纹之间的间距L可以在0.01～0.5mm的范 围之内选择，其中该间距L在图11中显示为相邻的两个凸起部或条纹的顶端之间的距离。进一步地，该凸起部或条纹的平均宽度的范围为0.04～0.6mm之间，平均高度H至少为0.1mm。。
对应于条状结构的尺寸，凸起部或条纹的平均截面积可设置为7x10 ‐4～0.2mm 2。此外，对于具体为凸起部的情况来说，每平方毫米的凸起部的数量至少为6个，平均高度至少为0.1mm。
对于条纹来说，可以平行设置也可为非平行设置。当条纹为非平行设置时，条纹之间的间距为该条纹任意一处位置与其相邻的条纹的最近的位置之间的间距。
进一步的，如图3(a)‐图3(i)和图4(a)‐(i)所示，反射变化部的外表面上加工有任意形状，以增加光线的吸收效果或反射效果。
如图3(i)和图4(i)所示的，加工的形状可以为波浪或尖锐的形状等。即反射变化部为非平整的平面。
作为一种实施方式，反射变化部的外表面整体的高度低于所在条状结构凸起的上顶面。
作为一种实施方式，反射变化部采用激光雕刻而成。对于条状结构的加工效率高，且表面光洁度较好。激光加工后可以对加工后的表面进行表面处理，以增加表面光洁度，增加光线反射效果。
更为优选的方案，可以采用喷砂处理等去除表层的方式进行处理，以去除表面的激光高温氧化层。
更为优选的另一种方案，采用激光抛光的方式对条状结构的第一侧壁或第二侧壁进行处理，抛光效果好，而且雕刻完毕后，直接进行抛光，处理效率高。
如图7(a)和图7(b)所示，第一图像与第二图像内容不同。当然，第一图像与第二图像内容也可以相同。但视角不同。
如图7(a)和图7(b)所示，第一侧壁的反射变化部和第二侧壁的反射变化部的结构可以为一个，也可为多个，且位于同一侧壁的反射变化部彼此之间的结构也可以不同。
提供一种轮胎模具，以生产上述轮胎。
如图5(a)‐图5(f)和图6(a)‐图6(f)所示，分别为轮胎模具的第一视角示意图和第二视角示意图，其分别与如3(a)‐图3(e)和图4(a)‐图4(e)的轮胎实施例的示意图相对应，轮胎模具腔内，与轮胎壁面上的条状结构相对应的位置上，设置有与轮胎壁面双向辨识部位形状互补的结构。
即具有多个并排设置的槽状结构，其中，若干槽状结构的第一侧壁具有反射变化部；
同一组或/和其他组的若干槽状结构的第二侧壁具有反射变化部；
使得生产的轮胎能够于第一视角可视第一图像，于第二视角可视第二图像，实现双向辨识。
在其他实施方式中，如图8(a)‐图8(c)以及图9(a)‐图9(c)所示，反射变化部不是缺口，而是在原有的条状结构上多增加一些部分，且该部分上具有缺失，保证与其他条状结构或所在条状结构的其他部位的反射角度不一致。
进一步地，在以上各附图中所显示的条状结构的未设置反射变化部的一侧被显示为垂直的，不过，条状结构的未设置反射变化部的一侧也可略为倾斜，这同样在本申请的范围之内。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
上述虽然结合附图对本发明的具体实施方式进行了描述，但并非对本发明保护范围的限制，所属领域技术人员应该明白，在本发明的技术方案的基础上，本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本发明的保护范围以内。
