The invention relates to the technical field of automobile parts, and discloses a steering column with a two-stage crumple structure and a vehicle, the steering column comprises an upper core shaft and a lower core shaft, the upper core shaft is in spline connection with the lower core shaft, the steering column further comprises an upper protection pipe, a middle protection pipe and a lower protection pipe, the upper core shaft is rotatably arranged in the upper protection pipe, and the lower core shaft is rotatably arranged in the middle protection pipe and the lower protection pipe; the upper protection pipe is in sliding connection with one end of the middle protection pipe, the lower protection pipe is in sliding connection with the other end of the middle protection pipe, pressing mechanisms are arranged at the sliding connection positions of the upper protection pipe and the middle protection pipe and the sliding connection positions of the lower protection pipe and the middle protection pipe, each pressing mechanism comprises a protruding structure arranged on the middle protection pipe, a threaded through hole is formed in each protruding structure, and a pressing screw plug is in threaded connection with the interior of each threaded through hole. A gasket is arranged at the end, close to the upper protection pipe, of the pressing screw plug, and an adjusting body is arranged at the end, away from the pressing screw plug, of the gasket and abuts against the upper protection pipe. The peak value of the crumple force can be further reduced, and therefore the impact force brought to a driver when the driver collides with the steering wheel is reduced.
本发明涉及汽车零部件技术领域,公开了一种带二级溃缩结构的转向柱及车辆,转向柱包括上芯轴和下芯轴,上芯轴与下芯轴花键连接,还包括上护管、中护管和下护管,上芯轴转动的设置于上护管内,下芯轴转动的设置于中护管和下护管内;上护管与中护管的一端滑动连接,下护管与中护管的另一端滑动连接,上护管和下护管与中护管的滑动连接处均设置有压紧机构,压紧机构包括设置在中护管上的凸起结构,凸起结构上开设有螺纹通孔,螺纹通孔内螺纹连接有压紧螺塞,压紧螺塞靠近上护管的一端设置有垫片,垫片远离压紧螺塞的一端设置有调整体,调整体与上护管相抵。本发明能够进一步降低溃缩力的峰值,从而减小因驾驶员撞击方向盘时对驾驶员带来的冲击力。
