An electric sliding rail device of a vehicle seat comprises a pair of sliding rails which are symmetrically arranged and both provided with rail inner cavities, and open grooves are formed in the surfaces of the upward sides of the sliding rails, and is characterized in that a pair of rack plates and a sliding mechanism rotationally connected with the rack plates are arranged in the rail inner cavities and located on bottom panels of the sliding rails; an unlocking assembly and a driving mechanism are installed on the upper portions of the two sliding mechanisms, each sliding mechanism comprises a sliding seat and a gear sliding assembly, each gear sliding assembly comprises a pair of rotating gear pieces and a sliding seat driving block, each driving mechanism comprises a driving motor, a reduction gearbox, a driving spline shaft and two driving gear assemblies, and the reduction gearboxes are connected with the unlocking assemblies. The driving gear assembly is connected with the rotating gear pieces and can drive the rotating straight gears of the two rotating gear pieces to rotate on the corresponding rack plates so as to achieve front-back sliding of the sliding base. The stability of the vehicle seat in the front-and-back sliding process is guaranteed, pause is avoided in the starting process, locking is stable, and the service life is long.

    一种车辆座椅的电动滑轨装置,包括一对滑动轨道,对称设置且两者均具有轨道内腔,滑动轨道的朝向上一侧表面上设开口槽,特点:在轨道内腔内且在滑动轨道的底面板上有一对齿条板以及一与齿条板转动连接的滑动机构,两个滑动机构的上部安装有解锁组件和驱动机构,滑动机构包括滑动座、齿轮滑动组件,齿轮滑动组件包括一对转动齿轮件及滑动座驱动块,驱动机构包括驱动电机、减速箱、驱动花键轴及两个驱动齿轮组件,减速箱与解锁组件连接,驱动齿轮组件与转动齿轮件连接并能驱动两个转动齿轮件的转动直齿轮在各自所对应的齿条板上转动而实现滑动座的前后滑动。保证车辆座椅前后滑动过程中的稳定性、启动时不会出现顿挫感、锁止稳定且使用寿命长。
