The invention relates to an electric long sliding rail which comprises lower sliding rails located on the left side and the right side respectively, transmission lead screws are rotationally installed in the two lower sliding rails respectively, and upper sliding rails capable of moving front and back along the lower sliding rails are installed on the transmission lead screws of the two lower sliding rails. A driving mechanism is fixedly installed between the two lower sliding rails, reduction gear boxes are arranged at the positions, corresponding to the driving mechanism, in the two lower sliding rails respectively, the driving mechanism is connected with the power input ends of the reduction gear boxes on the two sides through transmission flexible shafts, and the power output ends of the reduction gear boxes are connected with the driving end of the transmission lead screw. According to the automobile seat sliding rail, the defect that the height of a seat is relatively high due to the fact that more avoiding space is reserved for front-back displacement of an electric drive part in a traditional automobile seat sliding rail can be overcome, and the requirement for the low sitting posture state of the seat is met.
本申请涉及一种电动长滑轨,包括分别位于左右两侧的下滑轨,两下滑轨内分别转动安装有传动丝杆,两下滑轨于传动丝杆上安装有可沿下滑轨前后位移的上滑轨;两下滑轨之间固定安装有驱动机构,两下滑轨内与驱动机构相对应的位置分别设置有减速齿轮箱,驱动机构通过传动软轴与两侧的减速齿轮箱的动力输入端连接,减速齿轮箱的动力输出端与传动丝杆的驱动端连接。本申请可以改善传统汽车座椅滑轨中给电驱部分前后位移预留的较多避让空间,而导致座椅高度相对较高的缺陷,以实现座椅低坐姿状态的需求。
