The invention provides an automobile seat sliding rail mechanism. The sliding rail mechanism comprises a lower sliding rail and an upper sliding rail which is matched with the lower sliding rail and can slide relative to the lower sliding rail, wherein a locking assembly is arranged between the lower sliding rail and the upper sliding rail and used for locking the relative position between the lower sliding rail and the upper sliding rail, and an unlocking handle capable of unlocking the locking assembly is arranged on the upper sliding rail; the automobile seat sliding rail mechanism further comprises a memory sliding rail fixedly arranged on the lower sliding rail, a lower memory assembly slidably arranged in the memory sliding rail, an upper memory assembly fixedly arranged on the upper sliding rail and an external driving assembly in transmission connection with the locking assembly and a driving piece. According to the automobile seat sliding rail mechanism, the structure of the external driving assembly can be simplified, the fit clearance between the automobile seat sliding rail mechanism and the external driving assembly can be eliminated, a large degree of tolerance can be achieved, a problem of unlocking asynchronism can be avoided, use stability of the mechanism can be improved, meanwhile, occupation of the space outside the sliding rail can be reduced, and the overall light weight of the mechanism is facilitated.

    本发明提供了一种汽车座椅滑轨机构,其包括下滑轨,以及与下滑轨匹配设置并可相对下滑轨滑动的上滑轨,于下滑轨和上滑轨之间设有以锁定两者间相对位置的锁止组件,且于上滑轨上设有可解锁锁止组件的解锁手柄,汽车座椅滑轨机构还包括固定设于下滑轨上的记忆滑轨,可滑动的设于记忆滑轨中的下记忆组件,固定设于上滑轨上的上记忆组件,以及分别与锁止组件及驱动件传动相连的外部驱动组件。本发明的汽车座椅滑轨机构能够简化外部驱动组件的结构,可消除与外部驱动组件之间的配合间隙,能够有较大程度的容差量,可规避解锁不同步的问题,提高机构使用稳定性,同时也可减少对滑轨外空间的占用,并有利于机构整体的轻量化。
