The invention relates to a length adjustment guide structure of a long-stroke adjustment steering column. Comprising a supporting sleeve and an inner pipe column, the inner pipe column is arranged in the supporting sleeve, and an energy absorption structure, a length adjusting support, a guide strip and a baffle are sequentially arranged between the inner pipe column and the supporting sleeve from inside to outside; the energy absorption structure is fixed to the side wall of the inner tubular column, the length adjusting support is installed on the energy absorption structure, the length adjusting support is connected with the guide block through a bolt, the guide block slides in the guide strip, the guide strip is arranged in a long limiting groove formed in the side wall of the supporting sleeve, and a baffle is arranged outside the guide strip. And the baffle is in bolted connection with the supporting sleeve. The longitudinal long limiting groove is formed in the side wall of the supporting sleeve, then the lead screw of the motor is lengthened, and the second guide block is additionally arranged, so that the flatness and stability of the inner tubular column during length adjustment are improved while long-stroke adjustment is achieved.

    本发明涉及一种长行程调节转向管柱的长度调节导向结构。包括支撑套筒、内管柱,所述内管柱置于支撑套筒内,在内管柱与支撑套筒之间从内向外依次设有吸能结构、长度调节支架、导向条、挡板;所述吸能结构固定在内管柱侧壁上,长度调节支架安装在吸能结构上,所述长度调节支架上通过螺栓连接导向块,导向块在导向条内滑动,所述导向条置于支撑套筒侧壁开的长限位槽内,在导向条外面设有挡板,所述挡板与支撑套筒螺栓连接。本申请在支撑套筒侧壁上开有纵向长限位槽,再加长电机的丝杆,并且增设第二导向块,实现长行程调节的同时,提高长度调节时内管柱的平稳定。
