The invention relates to a collapsible rack and a steering system, the collapsible rack comprises at least two racks, the at least two racks are coaxially arranged, and a collapsing structure is arranged between two adjacent racks in the at least two racks; the two adjacent racks comprise a first rack and a second rack; the crumple structure comprises a first crumple connecting part arranged in the axial direction of the first rack and a second crumple connecting part arranged in the axial direction of the second rack, and the second crumple connecting part is movably arranged in the first crumple connecting part; an elastic clamping structure is arranged on the second crumple connecting part, and the elastic clamping structure comprises an elastic piece and a clamping piece; the elastic piece is arranged in the radial direction of the second rack, connected with the clamping piece and used for providing elastic force close to the first crumple connecting part for the clamping piece. In the embodiment of the invention, the crumple structure enables the deformation of the rack to be along the length direction of the rack, the direction control function of the steering system is not influenced, and meanwhile, the elastic clamping structure is arranged, so that the sectional rack is prevented from falling off in daily use.
本申请涉及一种可溃缩齿条及转向系统,该可溃缩齿条包括至少两个齿条,至少两个齿条同轴设置,至少两个齿条中的两个相邻齿条之间均设置有溃缩结构;两个相邻齿条包括第一齿条和第二齿条;溃缩结构包括沿第一齿条轴向设置的第一溃缩连接部和沿第二齿条轴向设置的第二溃缩连接部,第二溃缩连接部活动设置在第一溃缩连接部中;第二溃缩连接部上设置有弹性卡定结构,弹性卡定结构包括弹性件和卡定件;弹性件沿第二齿条径向设置,并与卡定件相连接,用于为卡定件提供靠近第一溃缩连接部的弹力。本申请实施例中,溃缩结构使齿条的形变沿齿条长度方向,不会影响转向系统的方向控制功能,同时设置弹性卡定结构,防止分段式的齿条在日常使用时发生脱落。
