The invention relates to an automobile seat sliding rail which comprises an outer sliding rail body, an inner sliding rail body and a locking mechanism. Tooth structures are arranged on the outer sliding rail at intervals in the longitudinal direction, lock holes are formed in the inner sliding rail at intervals in the longitudinal direction, and connecting teeth are arranged between every two adjacent lock holes. The locking mechanism comprises a locking clamp and a locking spring, the top of the locking clamp penetrates through a mounting hole formed in the top wall of the inner sliding rail, the bottom of the locking clamp is bent and is provided with locking teeth at intervals in the longitudinal direction, each locking tooth comprises a tooth root part and a tooth tip part, the locking teeth can penetrate through the locking holes to enable the tooth root parts to be located in the locking holes, and the locking spring can act on the locking clamp to enable the tooth tip parts to be matched with the tooth structures; and limiting grooves are correspondingly formed in the opposite sides of the tooth root portions of at least one set of two adjacent locking teeth, and the two side edges of the corresponding connecting teeth are located in the limiting grooves respectively and can move in the height direction. The overall structure of the automobile seat sliding rail can be simplified, the weight is reduced, the requirement for the machining precision of the lock clamp is lowered, and cost is reduced.

    本发明涉及一种汽车座椅滑轨,包括外滑轨、内滑轨和锁止机构;外滑轨沿纵向间隔设有齿结构,内滑轨沿纵向间隔设有锁孔,相邻两个锁孔之间设有连接齿;锁止机构包括锁卡和锁紧弹簧,锁卡的顶部穿过设于内滑轨顶壁的安装孔,锁卡的底部折弯并沿纵向间隔设有锁齿,锁齿包括齿根部和齿尖部,锁齿能够穿过锁孔使齿根部位于锁孔内,锁紧弹簧能够作用于锁卡使齿尖部与齿结构配合;至少一组相邻两个锁齿的齿根部相对的一侧对应设有限位槽,对应的连接齿的两侧边分别位于限位槽内并可沿高度方向移动。能够简化汽车座椅滑轨的整体结构并减轻重量,降低对锁卡的加工精度要求并降低成本。
