The utility model relates to the field of automobile steering columns, and particularly discloses an automobile steering column collapsing structure with stable collapsing force. The automobile steering column collapsing structure comprises an upper column, a lower column and a mounting bracket, wherein the mounting bracket comprises a mounting plate and a clamping arm; a fixing bracket is arranged on the upper tubular column, and a limiting hole is formed in the fixing bracket; the limiting hole is a long-strip-shaped hole extending in the axial direction of the upper pipe column. A stop block corresponding to the upper end face of the clamping arm is arranged on the outer side face of the upper pipe column. According to the automobile steering column crumpling structure, the crumpling process is divided into a buffer section and a crumpling section, and the crumpling structure has the effects of stabilizing crumpling force and moving the peak value of the crumpling force backwards. 本实用新型涉及汽车转向管柱领域，具体公开了一种溃缩
