The crumple structure of the steering column comprises a C-shaped support, an energy absorption piece, a toothed stone assembly and a cam block, the C-shaped support and the energy absorption piece are arranged on one side of a column pipe, the C-shaped support is connected with the upper plane of the energy absorption piece through a rivet, the energy absorption piece is provided with a tooth-shaped structure with two-way insections, and the tooth-shaped structure is connected with the cam block. A supporting sleeve is arranged outside the column pipe provided with the C-shaped support and the energy absorption piece in a sleeved mode, a tooth stone assembly is arranged in a through hole in the side, opposite to the tooth-shaped structure, of the supporting sleeve, one end of the tooth stone assembly penetrates through the supporting sleeve to be meshed with bidirectional insections of the tooth-shaped structure, and the other end of the tooth stone assembly is in contact with a cam block. And the cam block is arranged on the handle shaft. According to the invention, the clamping stagnation phenomenon can be reduced, the collapse function failure is effectively prevented, and the user experience is improved.

    本发明公开了一种转向柱的溃缩结构,包括C型支撑、吸能片、齿石总成和凸轮块,柱管的一侧设有C型支撑和吸能片,所述C型支撑通过铆钉与吸能片的上平面相连,所述吸能片上带有双向齿纹的齿形结构,设有C型支撑和吸能片的柱管的外部套有支撑套筒,所述支撑套筒相对齿形结构的一侧通孔内设有齿石总成,所述齿石总成的一端穿过支撑套筒与齿形结构的双向齿纹啮合,所述齿石总成的另一端与凸轮块相接触,所述凸轮块设在手柄轴上。本发明可以降低卡滞现象,有效防止溃缩功能失效,并提高用户体验。
