The invention discloses an automobile steering pipe column assembly and a pull-off structure thereof. The pull-off structure comprises an installation plate installed on a pipe beam and a support plate installed on a pipe column. The installation plate and the support plate are fixedly connected through collapsing pieces. A first sliding guide piece is arranged on the installation plate, a second sliding guide piece matched with the first sliding guide piece in a sliding guide mode is arranged on the support plate, and the sliding guide direction of the first sliding guide piece and the second sliding guide piece is the gravity direction of the support plate. When a collision happens and the pipe column collapses, the installation plate is fixed to the pipe beam, the support plate moves downwards along the installation plate under the effect of the first sliding guide piece and the second sliding guide piece, and the sliding distance of the support plate is limited by the sliding guide distance of the two sliding guide pieces. By designing the sliding guide distance, it can be avoided that a steering wheel connected with the support plate falls and injuries the legs of a driver, and it is guaranteed that the buffer effect of an airbag is brought into full play.
