The invention relates to an electric long sliding rail of an automobile seat and a transmission method of the electric long sliding rail. A right sliding rail body and a left sliding rail body each comprise an upper sliding rail body, a lower sliding rail body, a lead screw transmission mechanism and a gearbox, the lead screw transmission mechanism comprises a lead screw and two linked worm and gear transmission boxes; the lead screw is in transmission connection with the two worm and gear transmission cases, the lead screw is fixedly installed on the lower sliding rail, the gearbox and the two worm and gear transmission cases are all installed on the upper sliding rail, and the gearbox is in transmission connection with one of the worm and gear transmission cases; and the motor assembly is in transmission connection with the two gearboxes. The two linked worm and gear transmission boxes are both in transmission connection with the lead screw, on one hand, the strength is guaranteed, on the other hand, two transmission points are arranged, the lead screw is not prone to deflection deformation, and the worm and gear transmission boxes have the self-locking function; the gearbox is designed, on one hand, the time needed by the full stroke of the long sliding rail is shortened, on the other hand, the installation height of the double-shaft motor is increased through the gearbox, and installation of the motor is facilitated.

    本发明涉及一种汽车座椅电动长滑轨及其传动方法,右滑轨和左滑轨均包括相互滑动连接的上滑轨和下滑轨,以及丝杆传动机构和变速箱;丝杆传动机构包括一根丝杆和两个联动的蜗轮蜗杆传动箱;丝杆与两个蜗轮蜗杆传动箱传动连接,丝杆固定安装在下滑轨上,变速箱和两个蜗轮蜗杆传动箱均安装在上滑轨上,变速箱与其中一个蜗轮蜗杆传动箱传动连接;电机组件与两个变速箱传动连接。本申请中的两个联动的蜗轮蜗杆传动箱均与丝杆传动连接,一方面强度得到保证,另一方面有两个传动点,丝杆不轻易发生挠曲变形,且蜗轮蜗杆具有自锁功能;设计了变速箱,一方面减少了长滑轨满行程所需时间,另一方面变速箱抬高了双轴电机的安装高度,方便电机的安装。
