[0002] The steering column is a steering mechanism used by cars to connect the steering wheel and the steering gear. With the maturity of automobile technology, people pay more and more attention to the safety performance of cars. In order to better protect the driver in the event of a collision, a collapse structure is usually set on the steering column so that the steering column can produce axial collapse in the event of a collision, absorb part of the impact energy and provide more space to reduce damage to the driver's head and chest. Due to the differences in the collapse stroke and layout space of the steering columns of different models, there are many types of pull-off mechanism structures, some of which require a large layout space and some of which have complex processes. For example, a steering column collapse structure with announcement number CN212861606U, although its collapse block assembly structure is relatively compact, has a complex process, many parts, and is rarely platformized and universally used. Therefore, it is necessary to invent a new automobile steering column pull-off structure. Utility Model Content

[0022] like Figures 1 to 7The illustrated automobile steering column pull-out structure includes a column mounting bracket 1, which is a steering column mounting point and is fixed to an instrument cross beam by bolts and to an upper column tube by an adjustment mechanism. The column mounting bracket 1 is connected to a steering column housing by bolts. Pull-out grooves 11 are provided on both sides of the column mounting bracket 1, and a pull-out block assembly is movably connected to a position corresponding to the pull-out groove 11 on the column mounting bracket 1, and limiting sliding grooves 21 adapted to the wall thickness of the pull-out groove 11 are provided on both sides of the pull-out block assembly, one end of the pull-out block assembly is fixedly connected to one end of a pull-out spring 32, and the other end of the pull-out spring 32 is fixedly connected to the column mounting bracket 1.
[0023] Preferably, in combination with the above scheme, in order to facilitate parts processing and assembly, the pull-off block assembly includes a pull-off block 2 and a pull-off sheet 3, the pull-off block 2 is fixedly connected to the pull-off sheet 3, the limiting slide groove 21 is arranged on both sides of the pull-off block 2, the lower end of the pull-off sheet 3 is fixedly connected to the upper end of the pull-off spring 32, and the lower end of the pull-off spring 32 is fixedly connected to the column mounting bracket 1. The left and right groups of pull-off blocks 2 are both aluminum alloy die-castings with basically the same appearance. The two groups of pull-off sheets 3 are symmetrically arranged, and can be designed into one or a small number of series of universal automotive steering column pull-off structures according to different collapse distances, space arrangements, and vehicle assembly fixture requirements.
[0024] Preferably, in combination with the above solution, the pull-off spring 32 is a torsion spring formed by rolling the pull-off strip into a ring shape.
