The invention relates to the technical field of vehicle steering, and provides an electrically adjustable steering column and an electric power steering system. The steering column capable of being electrically adjusted comprises a telescopic component, a first driving component and a second driving component, wherein the telescopic component comprises a first steering shaft and a first protective tube sleeving the first steering shaft; the driving component comprises a driving support arranged on the outer wall of the first protection pipe, and a first energy absorption groove extending in the axial direction is formed in a body part of the driving support; the energy absorption component comprises a first bolt which penetrates through the first energy absorption groove and extends into the first protection pipe, and the first bolt is fixedly connected with the first protection pipe and is in sliding fit with the first energy absorption groove; in the using stage, the first bolt is kept at the head end of the first energy absorption groove, and the driving component can drive the telescopic component to stretch out and draw back through the driving support. In the collapsing energy absorption stage, the telescopic component collapses and at least drives the first bolt to slide in the first energy absorption groove. The maintenance function during telescopic adjustment and the energy absorption function during collision collapse are achieved mainly through the bolts, the structure is simplified, and the cost is reduced.
本发明涉及车辆转向技术领域,提供一种可电动调节的转向管柱和电动助力转向系统。可电动调节的转向管柱包括:可伸缩部件,包括第一转向轴和套设于第一转向轴外的第一护管;驱动部件,包括设置于第一护管的外壁的驱动支架,驱动支架的本体部设有沿轴向延伸的第一吸能槽;吸能部件,包括穿过第一吸能槽伸入第一护管的第一螺栓,第一螺栓与第一护管固定连接且与第一吸能槽可滑动配合;于使用阶段,第一螺栓保持于第一吸能槽的首端,驱动部件能通过驱动支架驱动可伸缩部件伸缩;于溃缩吸能阶段,可伸缩部件溃缩,并至少带动第一螺栓在第一吸能槽中滑动。本发明主要通过螺栓实现伸缩调节时的保持功能和碰撞溃缩时的吸能功能,简化结构,降低成本。
