The invention relates to a steering column crumple energy absorption structure and a steering system.The steering column crumple energy absorption structure comprises an upper column and a lower column, one end of the lower column is slidably arranged at one end of the upper column in a sleeving mode, and the side wall of the upper column is fixedly connected with a guide strip extending in the axial direction of the upper column; the side wall of the lower pipe column is provided with a connecting opening allowing the guide strip to stretch out, the lower pipe column is fixedly connected with a crumple positioning plate located at the connecting opening, the crumple positioning plate is provided with a crumple guide groove allowing the guide strip to stretch in, and the groove wall of the crumple guide groove is in interference fit with the guide strip. The technical problems that according to an existing steering column crumpling scheme, crumpling force is unstable, and after crumpling occurs, a driver may be secondarily hurt can be solved.
本发明涉及一种转向管柱溃缩吸能结构及转向系统,其中,一种转向管柱溃缩吸能结构,包括上管柱和一端滑动并套设于所述上管柱一端的下管柱,所述上管柱的侧壁固定连接有沿其轴向延伸的导向条,所述下管柱侧壁开设有供所述导向条伸出的连接口,所述下管柱固定连接有位于所述连接口处的溃缩定位板,所述溃缩定位板开设有供所述导向条伸入的溃缩导向槽,所述溃缩导向槽的槽壁和所述导向条过盈配合。本发明可改善现有的转向管柱的溃缩方案的溃缩力不稳定,在发生溃缩后可能会对驾驶员造成二次伤害的技术问题。
