The invention discloses an automobile seat electric drive sliding device which comprises two sets of sliding rails arranged in parallel, the installation height of one set of sliding rails is larger than that of the other set of sliding rails, each set of sliding rails comprises a lower rail and an upper rail, a lead screw is arranged in each lower rail, a gear box is fixed in each upper rail, and a motor support is connected between the two sets of upper rails. A motor and a conversion gear box are installed on the motor support, a first flexible shaft and a second flexible shaft are coaxially arranged at the two axial ends of the motor, the first flexible shaft is in power connection with the gear box of the sliding rail on one side, and the second flexible shaft is connected to the input end of the conversion gear box. The output end of the conversion gear box is connected to the gear box of the sliding rail on the other side through a third flexible shaft. Through the arrangement of the conversion gearbox and the third flexible shaft, the device can adapt to the situation that the mounting heights of sliding rails on the two sides of seats of some special vehicle types are inconsistent, through the height design of the conversion gearbox, the device can be matched with different sliding rail height differences, and the device has the advantages of being high in adaptability, low in noise, stable in transmission and the like.
本发明公开了一种汽车座椅电驱动滑动装置,包括两组平行设置的滑轨,其中一组滑轨的安装高度高于另一组滑轨,两组滑轨均包括下轨和上轨,下轨内具有丝杆,上轨内固定有齿轮箱,两组上轨之间连接有电机支架,电机支架上安装有电机和转换齿轮箱,电机轴向两端具有同轴设置的第一软轴和第二软轴,其中第一软轴与其中一侧滑轨的齿轮箱动力连接,第二软轴连接至转换齿轮箱的输入端,转换齿轮箱的输出端通过第三软轴连接至另一侧滑轨的齿轮箱。本发明通过设置转换齿轮箱和第三软轴,能够适应部分特殊车型座椅两侧滑轨安装高度不一致的情况,通过转换齿轮箱的高度设计,可以匹配不同的滑轨高度差,具有适应性强,噪音小,传动平稳等优点。
