The invention relates to the field of automobile steering columns, and particularly discloses an automobile steering column crumple structure with stable crumple force. The automobile steering columncrumple structure comprises an upper column, a lower column and a mounting support, wherein the mounting support comprises a mounting plate and clamping arms; a fixed support is arranged on the uppercolumn, and a limiting hole is formed in the fixed support; the limiting hole is a long-strip-shaped hole extending in the axial direction of the upper column. Stop blocks corresponding to the upper end surfaces of the clamping arms are arranged on the outer side surface of the upper column. According to the automobile steering column crumple structure, the crumple process is divided into a buffering section and a crumpling section, and the effects of stabilizing crumpling force and moving the peak value of the crumpling force backwards are achieved.

    本发明涉及汽车转向管柱领域,具体公开了一种溃缩力稳定的汽车转向管柱溃缩结构。该汽车转向管柱溃缩结构包括上管柱、下管柱和安装支架,所述的安装支架包括安装板和夹持臂;所述的上管柱上设有固定支架,所述的固定支架上设有限位孔;所述的限位孔为沿上管柱的轴向延伸的长条形孔;所述上管柱的外侧面设有与夹持臂上端面对应的挡块。以上所述的汽车转向管柱溃缩结构将溃缩过程分为缓冲和溃缩两段,具有稳定溃缩力和将溃缩力峰值后移的作用。
