The invention discloses a crumple device of an electric adjusting tubular column, and relates to the field of electric adjusting tubular columns. A collapsing device of an electric adjusting tubular column comprises a lower tubular column and an upper tubular column, the upper tubular column is connected in the lower tubular column in a sliding mode, and the collapsing device further comprises rectangular shells which are symmetrically and fixedly connected to the two sides of the lower tubular column and integrally formed with the lower tubular column; the toothed plate is fixedly connected to one side of the upper tubular column and located in the rectangular shell; the bracket is fixedly connected to one side, close to the toothed plate, of the upper end of the lower tubular column; according to the strength of the impact force generated by the automobile, different crumple forces can be generated on the electric adjusting tubular column for energy absorption, so that no matter how large the impact force generated by the automobile is, the electric adjusting tubular column can generate the crumple force, the impact force is absorbed, and some impact force transmitted to a human body by a steering column due to impact is dispersed; therefore, the life safety of the driver can be better protected.
本发明公开了一种电动调节管柱的溃缩装置,涉及电动调节管柱领域。一种电动调节管柱的溃缩装置,包括下管柱和上管柱,所述上管柱滑动连接在下管柱内,还包括:矩形壳体,对称固定连接在所述下管柱的两侧,且与所述下管柱一体成型;齿板,固定连接在所述上管柱的一侧,且位于所述矩形壳体内;支架,固定连接在所述下管柱上端靠近齿板的一侧;本发明可以根据汽车发生撞击力的强度,来对电动调节管柱产生不同的溃缩力进行吸能,从而不管汽车产生多大的撞击力,都可以使电动调节管柱产生溃缩力,对撞击力进行吸能,分散一些因撞击由转向柱传递到人体的冲击力,以便更好的保护驾驶者的生命安全。
