The invention relates to an energy absorption device of a steering column. The invention relates to an energy-absorbing rack structure which is composed of a rack structure and an energy-absorbing structure, a main body of the rack structure is square, one side face facing a tubular column is arc-shaped, the other side face opposite to the arc-shaped side face is connected with an energy-absorbing piece, the rack structure is parallel to the tubular column, and one side face which is not connected with the energy-absorbing piece is provided with meshing teeth, and the energy-absorbing structure is divided into a rack connecting piece and the energy-absorbing piece. One end of the rack connecting piece is in bolted connection with the rack structure, the other end of the rack connecting piece is bent backwards to form an energy absorption piece, and the energy absorption piece, the rack connecting piece and the tubular column are parallel. Compared with an integrated structure in the prior art, the rack structure and the energy absorption structure of the energy absorption device are designed in a split mode, the rack structure and the energy absorption structure are selected according to the vehicle space, the meshing teeth can be selectively arranged on the specific side face of the rack structure according to actual needs, adaptability is high, the application range is wider, and the energy absorption device can adapt to different vehicles.
本发明涉及一种转向管柱的吸能装置。由齿条结构和吸能结构组成,所述齿条结构主体呈方形,朝向管柱一侧面为弧形,与弧形相对的另一侧面与吸能片连接,所述齿条结构与管柱平行且不连接吸能片的一个侧面上带有啮合齿,所述吸能结构分为齿条连接片和吸能片,所述齿条连接片的一端与齿条结构螺栓连接,所述齿条连接片另一端向后弯折成吸能片,所述吸能片、齿条连接片和管柱平行。本申请吸能装置的齿条结构和吸能结构分体设计,和现有技术中的一体结构相比,根据车辆空间而选择,啮合齿可以根据实际需要选择设置在齿条结构的具体哪个侧面上,适应性强,应用范围更广,可适应不同车辆。
