The invention provides a groove-crack-resistant and stone-clamping-resistant tire pattern design method and device and a tire. The method comprises the steps that it is determined that a tire pattern is of a variable-angle pattern groove structure; the pattern groove depth and the pattern groove width of the variable-angle pattern groove structure are determined; determining a side wall included angle based on the pattern groove depth and the pattern groove width; based on the included angle, a stone block discharging structure is determined and configured on one side wall of the pattern groove, the stone block discharging structure is used for discharging stone in the tire pattern, the height of the stone discharging structure is smaller than half of the depth of the pattern groove, the width of the stone discharging structure is smaller than the width of the pattern groove, and the surface of the stone discharging structure is an inclined plane. The stone discharging structure is arranged on one side wall of the variable-angle pattern groove structure, and the width and the high speed of the stone discharging structure are related to the size of the pattern groove, so that stones can be effectively discharged when encountering the stones, and the inclined surface of the stone discharging structure can also ensure the stone discharging efficiency.

    本发明提供一种抗沟裂防夹石的轮胎花纹设计方法、装置及轮胎,包括确定轮胎花纹为变角度花纹沟结构;确定变角度花纹沟结构的花纹沟深度和花纹沟宽度;基于花纹沟深度和花纹沟宽度,确定侧壁夹角;基于夹角,确定排石子块结构,并将排石子块结构配置于花纹沟的其中一个侧壁上,其中,排石子块结构用于排出轮胎花纹中的石子,排石子结构的高度小于花纹沟深度的一半,排石子结构的宽度小于花纹沟宽度,排石子结构的表面为倾斜面。由于变角度的花纹沟结构的一个侧壁上设置有排石子结构,并且排石子结构的宽度和高速与花纹沟的尺寸关系,使得遇到石子时,能够有效地将石子排出,排石子结构的倾斜表面,也能保证石子排出的效率。
