A clamping part is arranged on the side wall of a rail, the clamping part is clamped with a gear box arranged in the rail, and under the action of a threaded part in the gear box, the clamping part and the threaded part convert rotary motion into linear motion to drive the rail to move. The device is characterized in that the rail is composed of an upper rail and a lower rail which are mutually coupled, the clamping component comprises a transmission part, and the transmission part is separately fixed between the upper rail and the lower rail so that the threaded component can drive the rail through a non-metal transition connection structure and lock the rail through a metal connection structure. The non-metal transmission transition piece is additionally arranged on the sliding rail and the driving threaded piece to replace a metal sliding rail to be connected with a transmission mechanism, abnormal sound generated when metal threads are meshed with non-standard threads under the normal driving working condition is avoided, meanwhile, the characteristic that non-metal materials are destructive is utilized, locking of the sliding rail is achieved under the collision working condition, and the safety of passengers is guaranteed.
本发明公开了一种齿轮箱直驱滑轨,在轨道侧壁上设置有卡合部件,所述卡合部件与设置在轨道中的齿轮箱卡合,受所述齿轮箱内的螺纹部件作用,通过卡合部件与所述螺纹部件将旋转运动转化为直线运动驱动使所述轨道移动,其特征在于,所述轨道由相互耦合的上轨和下轨组成,所述卡合部件包括一传动件,所述传动件分离的固定于所述上轨与所述下轨之间使所述螺纹部件以非金属过渡连接结构驱动所述轨道,以金属连接结构锁止所述轨道。通过在滑轨和驱动螺纹件增设非金属传动过渡件替代金属滑轨与传动机构相接,避免正常驱动工况下金属螺纹与非标螺纹啮合时发生异响,同时利用非金属材质可破坏性的特点,在碰撞工况实现对滑轨的锁止,保证乘员安全。
