The present invention provides a rail-type telescopic electric column having a rail-type telescopic driving structure, moving the entire steering column assembly in the axial direction, and ensuring the amount of expansion and contraction of the steering column, thereby ensuring the space of a driver according to the development requirements of the unmanned driving technology and ensuring the structural rigidity at the same time. To this end, the present invention comprises: a rail base provided on a vehicle body; a steering column provided on the rail base so as to be slidable in the axial direction; a driving tool providing a driving force for sliding the steering column in an axial direction; wherein fixed rails extending in the axial direction are arranged on the two sides of the rail base respectively; rolling bearings are respectively arranged on two sides of the steering column, the rolling bearings are supported by the fixed rails, and when the steering column slides in the axial direction by the driving force of the driving tool, the rolling bearings rotate and move in the axial direction at the same time.

    本发明提供一种轨道可伸缩电动管柱,具有轨道方式的伸缩驱动结构,以轴方向移动整个转向柱组件,确保转向柱的伸缩量,由此根据无人驾驶技术的发展要求确保驾驶员的空间,与此同时可确保结构刚性。为此,本发明的轨道可伸缩电动管柱包括:轨道底座,设置在车身;转向柱,以轴方向可滑动地设置在所述轨道底座;驱动工具,提供以轴方向滑动所述转向柱的驱动力;其中,在所述轨道底座的两侧分别设置以轴方向延长的固定轨道;在所述转向柱的两侧分别设置滚动轴承,所述滚动轴承被所述固定轨道支撑,在所述转向柱通过所述驱动工具的驱动力以轴方向滑动时,所述滚动轴承进行旋转的同时以轴方向进行移动。
