The steering column crumple mechanism comprises an upper column pipe, a lower column pipe and a crumple assembly matched with the upper column pipe and the lower column pipe, the crumple assembly comprises a tearing steel belt and a guide part, the tearing steel belt is provided with a fixing steel belt, a bending steel belt and a tearing groove located between the fixing steel belt and the bending steel belt, the fixing steel belt and the upper column pipe are fixedly arranged, and the bending steel belt is arranged in the tearing groove. The bending steel belt and the lower column pipe are fixedly arranged, the guiding piece is installed on the upper column pipe and matched with the bending steel belt, and in the crumple stable stage, tearing of the tearing groove and deformation of the bending steel belt occur at the same time. In the crumple process, the tearing of the tearing groove and the deformation of the bending steel belt occur at the same time, stable crumple force is provided, the safety of the vehicle is improved, and the damage to a driver in the vehicle collision process is effectively avoided or reduced.
本申请提供一种转向管柱溃缩机构,包括:上柱管、下柱管及分别与上柱管、下柱管配合的溃缩组件,溃缩组件包括撕裂钢带及导向件,撕裂钢带设有固定钢带、绕曲钢带及位于固定钢带、绕曲钢带之间的撕裂槽,固定钢带与上柱管固定设置,绕曲钢带与下柱管固定设置,导向件安装在上柱管上并与绕曲钢带相配合,在溃缩稳定阶段,撕裂槽的撕裂与绕曲钢带的形变同时发生。在溃缩过程中,撕裂槽的撕裂及绕曲钢带的变形同时发生,提供了稳定的溃缩力,提高车辆安全性,有效避免或减少驾驶员在车辆碰撞中受到的伤害。
