Description

Novel automobile steering energy-absorbing pipe column assembly

Technical Field

The utility model relates to the field of automotive technology, specifically a novel car steering energy-absorbing tubular column assembly.

Background

In order to protect the safety of automobile passengers, the steering wheel needs to be collapsed in time when the automobile collides, so that a driver is not injured, and part of impact energy is absorbed, so that a steering system needs to be designed with a structure which is impacted by a large force to generate collapse energy absorption. At present, a frequently-adopted collapse structure is that an upper pipe column part covering a lower pipe column is generally subjected to pressure riveting, and displacement between the upper pipe column and the lower pipe column is limited through plastic deformation generated by the upper pipe column and the lower pipe column. When the second stage of collision occurs, the pipe column is severely impacted, the upper limit value and the lower limit value which can be borne by the plastic deformation are exceeded, the upper pipe column and the lower pipe column move, collapse occurs, and energy absorption is achieved. However, when the conventional automobile steering energy-absorbing pipe column assembly is assembled, disassembled, maintained and carried, the steering pipe column assembly can be greatly impacted, and at the moment, the upper mounting bracket is not fixed, so that the crumple energy-absorbing mechanisms of the upper pipe column and the lower pipe column can crumple in advance, and the pipe column crumple structure is ineffective.
