The invention relates to a steering column length adjusting mechanism. Comprising a length limiting structure, a telescopic pin shaft, a sleeve and a cam, the length limiting structure is fixed to the outer wall of a column tube of the steering column, the sleeve is fixed to a supporting piece outside the column tube, the telescopic pin shaft is inserted into the sleeve and penetrates through the sleeve, the telescopic pin shaft right faces a length adjusting limiting mechanism, one end of the cam is fixedly connected with a handle bolt, and the other end of the cam is fixedly connected with the handle bolt. The other end of the cam is arranged on the outer side of the pin shaft, the cam presses the telescopic pin shaft inwards, and the inner side face of the lower end of the cam comprises a high plane and a low plane. According to the adjusting structure, the collapsing function and the length adjusting function of the steering column are separated, and the problems that in the prior art, when the steering column collapses, a limiting part can be cut off or damaged, meanwhile, large force is generated, the large force fluctuates on the overall collapsing force, the collapsing force is increased, and the collapsing function is affected are solved.
本发明涉及一种转向柱长度调节机构。包括长度限位结构、可伸缩销轴、套筒、凸轮,所述长度限位结构固定在转向柱柱管外壁上,所述套筒固定在柱管外面的支撑件上,可伸缩销轴插入套筒并穿过套筒,可伸缩销轴正对着长度调节限位机构,所述凸轮一端与手柄螺栓固定连接,凸轮另一端置于销轴外侧,凸轮向内压紧可伸缩销轴,所述凸轮下端内侧面包括高平面和低平面。本申请调节结构将转向柱的溃缩功能和长度调节功能分离,解决了现有技术中当转向柱发生溃缩时,限位零件会被剪断或损坏同时产生一个较大的力,这个较大的力对整体的溃缩力产生波动,增大溃缩力,影响溃缩功能的效果。
