The crumple energy absorption structure comprises a C-shaped strip and sliding pieces, sliding guide grooves are formed in the opposite positions of the two side walls of the C-shaped strip, the sliding pieces are arranged in the sliding guide grooves in the two sides, and each sliding piece comprises a sliding end and a connecting end; a locking part extends from the sliding end in the direction towards the notch of the sliding guide groove, a hoop opening is formed in the locking part, and the sliding sheet is locked in the sliding guide groove through the mutual matching of the hoop opening and the locking bolt. According to the crumple energy absorption structure, energy absorption pieces and length adjusting supports in an existing crumple energy absorption structure are optimized, the newly-added sliding pieces slide in the sliding guide grooves, the groove edges of the sliding guide grooves are subjected to plastic deformation, energy absorption is completed, and therefore gaps do not need to be reserved between the structures; therefore, the loss of rigidity and strength caused by the steering column assembly in the crumple energy absorption process is greatly reduced, the occupied space is small, packaging is simple, and the phenomenon that the combination switch and the face recognition sensor shake or deflect is avoided.

    本发明公开了一种用于转向管柱的溃缩吸能结构,包括C型条和滑动片,所述C型条两侧壁的相对位置带有滑动导向槽,两侧所述滑动导向槽内设有滑动片,所述滑动片包括滑动端和连接端,所述滑动端朝向滑动导向槽槽口的方向延伸有锁紧部,所述锁紧部上带有箍口,所述滑动片通过箍口与锁紧螺栓的相互配合锁紧在滑动导向槽内。本发明优化掉了现有溃缩吸能结构中的吸能片及长度调节支架,通过新增的滑动片在滑动导向槽中滑动,使其槽边塑性形变完成能量的吸收,因此结构之间不用留有间隙,从而极大减小了转向管柱总成在溃缩吸能过程中对刚度及强度造成的损失,占用空间小,封装简单,避免了组合开关和面部识别传感器出现晃动或者偏转的现象。
