The invention relates to a lead screw type electric long sliding rail which comprises a lower sliding rail assembly, and a running mechanism which is supported and installed on the lower sliding rail assembly in a sliding mode and comprises an upper sliding rail assembly and a driving mechanism assembly used for driving the upper sliding rail assembly, wherein the upper sliding rail assembly comprises an upper sliding rail welding assembly and a gear box assembly installed on the upper sliding rail welding assembly, the driving mechanism assembly comprises a single motor and a synchronous rod driven by the motor, and the synchronous rod is inserted into the gearbox assembly to be matched so as to drive the gearbox assembly through the motor; and a lead screw that is arranged in the lower sliding rail assembly and penetrates into the gear box assembly to be matched with the gear box assembly. According to the lead screw type electric long sliding rail, the driving function and the locking/unlocking function can be achieved at the same time through a single motor, it is guaranteed that the electric long sliding rail is in the locking state all the time in the running process. As a result, once a vehicle collides, the position of a passenger can be effectively kept, and the purpose of protecting the passenger is achieved.

    本发明涉及一种丝杆式电动长滑轨,其包括下滑轨总成;可滑动地支撑安装在下滑轨总成上的运行机构,运行机构包括上滑轨总成和用于驱动上滑轨总成的驱动机构总成,上滑轨总成包括上滑轨焊接总成和安装在上滑轨焊接总成上的齿轮箱总成,驱动机构总成包括单个电机和被电机驱动的同步杆,同步杆插入齿轮箱总成中配合以通过电机来驱动齿轮箱总成;以及丝杆,其布置在下滑轨总成中并穿入齿轮箱总成中配合。根据本发明的丝杆式电动长滑轨丝杆式电动长滑轨,通过单个电机即可同时实现驱动和锁止/解锁功能,保证电动长滑轨在运行过程也时刻处于锁止状态,一旦车辆发生碰撞能有效保持乘员位置起到保护乘员的目的。
