The collapsing system of the integrated steering column comprises a column pipe and a supporting sleeve, the column pipe is installed in the supporting sleeve, a C-shaped supporting block set is arranged on one side of the column pipe, an energy absorption piece is riveted to the C-shaped supporting block set, and a rack is installed on the outer side of the energy absorption piece; a handle is installed on one side of the supporting sleeve, a handle shaft is arranged on the handle, a cam block is sleeved on the handle shaft, the cross section of the handle shaft and a through hole of the cam block are the same in shape so as to guarantee tight matching, the cam block is arranged inside the toothed stone, two sides of the toothed stone are contacted with the supporting sleeve, and the bottom end of the toothed stone is contacted with the supporting sleeve through an elastic piece. And the tooth-shaped part at the upper end of the toothed stone is matched with the rack through extrusion of the elastic piece. The crumple structure is integrated on the column tube of the steering column, crumple force can be provided while the handle is opened and closed to adjust the length of the column tube, the structural arrangement is reasonable, and the space utilization rate is high.

    本发明提供一种集成式转向柱的溃缩系统,包括柱管和支撑套筒,柱管安装在支撑套筒内,柱管的一侧设置有C型支撑块组,C型支撑块组上铆接有吸能片,吸能片的外侧安装有齿条;支撑套筒的一侧安装有手柄,手柄上设置有手柄轴,手柄轴上套装有凸轮块,手柄轴的截面与凸轮块的通孔形状相同以保证其紧密配合,凸轮块设置在齿石内部,其中齿石的两侧与支撑套筒相接触,齿石的底端通过弹性件与支撑套筒相接触,齿石的上端齿形部通过弹性件的挤压与齿条相互配合。本发明将溃缩结构集成在转向柱的柱管上,在手柄开启关闭起到调整柱管长度的同时,也能提供溃缩力,结构布置合理,空间利用率高。
