Electrically adjustable steering column and electric power steering system

Abstract

The present disclosure relates to the technical field of vehicle steering, and provides an electrically adjustable steering column and an electric power steering system. The electrically adjustable steering column includes: a telescopic component including a first steering shaft and a first protective jacket sleeved on the first steering shaft; a drive component including a drive bracket disposed on an outer wall of the first protective jacket, wherein a main body of the drive bracket is provided with a first energy absorption slot extending in an axial direction; an energy absorption component including a first bolt passing through the first energy absorption slot and extending into the first protective jacket, wherein the first bolt is fixedly connected to the first protective jacket and in a sliding fit with the first energy absorption slot; when in a use stage, the first bolt is maintained at a head end of the first energy absorption slot, and the drive component is capable of driving the telescopic component to expand and contract through the drive bracket; when in a collapse and energy absorption stage, the telescopic component collapses and drives at least the first bolt to slide in the first energy absorption slot. The present disclosure realizes a maintaining function during telescopic adjustment and an energy absorbing function during collision and collapse mainly by the bolt, thereby simplifying the structure and reducing the cost.
