The invention relates to the technical field of steering columns, in particular to a three-section telescopic electric adjusting steering column which comprises an outer pipe, a middle pipe, an inner pipe, a motor, a bevel gear, a lead screw thread sleeve, a lead screw, a lead screw nut, a rivet and an energy absorption belt. One motor is adopted to achieve simultaneous contraction and extension of three sections of column tubes, long-distance extension is achieved, meanwhile, the axial arrangement space of the column is saved, the structure of the column is compact, and the matching performance of the steering column and a whole vehicle is better; the energy absorption structure is additionally arranged, the structure is simple, the production cost is low, crumple energy absorption required by the whole vehicle is achieved, and the stress requirement of laws and regulations for a driver in the whole vehicle collision process is met.

    本发明涉及转向管柱技术领域,具体地说是一种三段式伸缩的电动调节转向管柱,包括外管、中间管、内管、电机、斜齿轮、丝杆螺套、丝杆、丝杆螺母、铆钉、吸能带,本发明同现有技术相比,设计了三段式伸缩的电动调节转向管柱,采用一个电机实现三段柱管同时收缩和伸长,实现长距离伸缩的同时,节省了管柱轴向布置空间,管柱结构紧凑,使转向管柱与整车的匹配性更好;增加了吸能结构,结构简单,生产成本低,实现了整车需求的溃缩吸能,满足了法规对于驾驶员在整车碰撞中的受力要求。
