According to the side window glass guide rail structure, the automobile door and the automobile, a plurality of low-friction-resistance wear-resistant materials POM are added to a guide rail body, after the POM is added, the friction resistance can be reduced, the wear resistance can be improved, and the local size stability is better than that of PA6. The problems that a traditional guide rail is large in friction coefficient and short in service life are solved. The elastic bridge is added to reduce the tolerance requirement of the contact area with the opponent piece, widen the process window and reduce the production control difficulty. Meanwhile, a space which is enough for shrinkage is designed and reserved between the POM and the PA6 to accommodate shrinkage change, so that product bending caused by different shrinkage rates is prevented. In addition, a wave structure is arranged at the contact position of the guide rail body and the glass, the contact area of PU glue is increased, and the bonding effect is improved.
本发明公开了一种侧窗玻璃导轨结构、车门及汽车,该结构在导轨主体上增加多处低摩阻的耐磨材料POM,采用增加POM后,可以降低摩擦阻力,增加耐磨性,局部的尺寸稳定性优于PA6。解决了传统导轨摩擦系数大导轨使用寿命短的问题。增加弹桥可以降低与对手件接触区域的公差要求,加宽工艺窗口,降低生产控制难度。同时,在POM和PA6之间设计预留足够收缩的空间,来容纳收缩变化,防止发生由于收缩率不同造成产品弯曲。另外,在导轨主体与玻璃接触处设置波浪结构增加了PU胶的接触面积提高了粘结效果。
