The invention discloses an electric steering pipe column mechanism used for an automobile. The electric steering pipe column mechanism comprises an inner spline, an outer spline and a spline sleeve, the inner spline is arranged on the inner wall of the bottom of an input shaft, the outer spline is arranged outside the top end of an output shaft, and the spline sleeve is used for connecting the inner spline and the outer spline and formed by multiple hollow cylinders arranged in the circumferential direction. A preset interval is formed between every two adjacent hollow cylinders, part of the hollow cylinders are provided with C-type grooves, and the other part of the hollow cylinders are provided with rolling pins. The teeth of the inner spline and the teeth of the outer spline are semicircular, and the hollow cylinders are matched with the semicircular teeth of the inner spline and the semicircular teeth of the outer spline. Through the combination of flexible and rigid designs, the problem of poor rigidity caused by abnormal sounds is effectively solved.
