所述中心部102的高度范围为：0.1～1mm；所述延伸部103的长度为： 0.2～1mm；中心部102的中心距离延伸部103的端部的距离为：0.2～1.5mm；相邻两个所述图案单元101的中心之间的距离为：0.7～5mm，优选为1-3mm；作为优选方案，该距离指中心部的中心之间的距离。The height of the central portion 102 ranges from 0.1 to 1 mm; the length of the extending portion 103 is 0.2 to 1 mm; the distance between the center of the central portion 102 and the end of the extending portion 103 is 0.2 to 1.5 mm; adjacent The distance between the centers of the two pattern units 101 is: 0.7 to 5 mm, preferably 1-3 mm; and preferably, the distance refers to the distance between the centers of the center portions.

延伸部103或中心部102的侧壁延伸设有分支105，当分支105位于延伸部103侧壁上时，该分支105可以倾斜于该延伸部103的延伸方向。和/或，图案单元的空白区域设有柱型或分支。柱形或分支与垂直于胎体的平面之间形成的角度为5°至30°，优选在15°至25°的范围内。The side wall of the extension portion 103 or the central portion 102 is extended with a branch 105.

And/or, the blank area of the pattern unit is provided with a column or a branch. The angle formed between the cylinder or the branch and the plane perpendicular to the carcass is 5 to 30, preferably 15 to 25.
在轮胎侧部的花纹区域中，入射到形成在花纹区域内的各凸起的光打到相邻的侧壁面。由于光在各侧壁面之间来回反射，因此光衰减了。因此，几乎没有光被反射回花纹区域的外部，使得花纹区域看起来为黑色，而相比之下其它区域(文字区域和轮胎侧部的其余部分)看起来为白色。由此，这能够在花纹区域与其他区域之间形成对比。提高了花纹部分与花纹不覆盖区域的外观的对比度。In the pattern region of the side portion of the tire, light incident on each of the projections formed in the pattern region hits the adjacent side wall surface. Since light is reflected back and forth between the side wall faces, the light is attenuated. Therefore, almost no light is reflected back to the outside of the pattern area, so that the pattern area appears black, while the other areas (the text area and the rest of the tire side) appear white in comparison. Thereby, this enables a contrast to be made between the pattern area and the other areas. The contrast of the appearance of the pattern portion and the uncovered area of the pattern is improved.
图1-图12、图16-图18中，图案单元101具有圆形的中心部102以及连接在中心部102的9个延伸部103。In FIGS. 1 to 12 and 16 to 18, the pattern unit 101 has a circular center portion 102 and nine extending portions 103 connected to the center portion 102.
图1中的图案单元相邻两个图案单元的中心之间的距离L3为0.7-5mm。中 心部102的中心距离延伸部103的端部L1的距离为：0.2～1.5mm；相邻两个所述图案单元101的中心之间的距离L3为：0.7～5mm，优选为1-3mm；中心部的中心距离同一个图案单元的中心部最远一点的距离L2小于0.4mm。The distance L3 between the centers of adjacent pattern units of the pattern unit in Fig. 1 is 0.7-5 mm. The distance between the center of the central portion 102 and the end portion L1 of the extending portion 103 is 0.2 to 1.5 mm; the distance L3 between the centers of two adjacent pattern units 101 is 0.7 to 5 mm, preferably 1-3 mm; The distance L2 at the center of the center portion from the center of the same pattern unit is less than 0.4 mm.
图2中，每个图案单元周围有9个延伸部，每个图案单元周围有6个相同方向排布的图案单元围绕。围绕的6个图案单元和被围绕的图案单元之间呈一定的规律排布，保证图案单元之间的每一块空白区域面积尽可能的缩小。这种规律可以为每个图案单元的延伸部的端部，都会***相邻图案单元的两个延伸部之间的空白区域。例如，图2中所示的排布方式，图案单元既是围绕图案单元、也是被围绕图案单元；以第三图案单元3作为被围绕单元为例，其周围分别有6个被围绕图案单元；第三图案单元3的上部的延伸部延伸插设在第二图案单元2的两个延伸部的中间的空白区域中；与第二图案单元2相邻的第一图案单元1的一个延伸部延伸插设在第三图案单元3的两个延伸部的中间的空白区域中；其他的4个图案单元按照相同的排布方式围绕第三图案单元3排布设置。通过采用这种方式，能够保证相邻图案单元之间空白区域的面积尽可能小，从而使胎侧花纹的视觉效果更佳。同时，在对模具加工时，可以更高效的排布胎侧花纹的图案单元的图案，只需要将图案单元按照一定的规律进行复制重复即可。In Fig. 2, there are 9 extensions around each pattern unit, and each pattern unit is surrounded by 6 pattern units arranged in the same direction. The surrounding six pattern units and the surrounding pattern units are arranged regularly to ensure that the area of each blank area between the pattern units is reduced as much as possible. This rule can be such that the end of the extension of each pattern unit is inserted into a blank area between the two extensions of adjacent pattern elements. For example, in the arrangement shown in FIG. 2, the pattern unit is both around the pattern unit and also around the pattern unit; taking the third pattern unit 3 as the surrounded unit as an example, there are 6 surrounding pattern units respectively; An extension of an upper portion of the three pattern unit 3 extends in a blank area intermediate the two extensions of the second pattern unit 2; an extension of the first pattern unit 1 adjacent to the second pattern unit 2 is extended The blank area is provided in the middle of the two extensions of the third pattern unit 3; the other four pattern units are arranged around the third pattern unit 3 in the same arrangement. By adopting this method, it is possible to ensure that the area of the blank area between adjacent pattern units is as small as possible, thereby making the visual effect of the sidewall pattern better. At the same time, when processing the mold, the pattern of the pattern unit of the sidewall pattern can be arranged more efficiently, and only the pattern unit needs to be duplicated and repeated according to a certain rule.
