The invention relates to a variable-crumple-force crumpling mechanism for a steering column. An outer sleeve of the steering column has an inner tube and an outer tube which are arranged coaxially andare non-rotatable relative to each other, and the outer tube at least partially encircles the inner tube on the outside. The crumpling mechanism comprises a solenoid valve with an extendable bolt, acrumple guide box fixed at the end part of the outer tube, a crumple stop block being fixed on the inner tube and being embedded into a crumple opening formed in the end part of the outer tube in an interference fit manner, a plurality of crumple pieces and spacers, wherein the plurality of crumple pieces and the spacers are sequentially and alternately arranged. The solenoid valve is fixed on thecrumple guide box; the plug pin is configured to be capable of being inserted into a plug pin hole; the crumple pieces and the spacers have the same shapes and are respectively provided with throughholes with the same shapes as the plug pin hole at the positions aligned with the plug pin hole in the crumple guide box, and the plug pin can be actuated by a magnetic force generated by the solenoidvalve and extends towards the through holes of the crumple pieces and the spacers.

    本发明涉及一种用于转向管柱的溃缩力可变的溃缩机构,转向管柱的外套管具有同轴地布置的不可相对转动的内管和外管,外管在外侧至少部分地包围内管,溃缩机构包括:带有可伸展的插销的电磁阀;固定在外管的端部上的溃缩导向盒;固定在内管上并且以过盈配合的方式嵌入到设置在外管端部上的溃缩开口中的溃缩挡块;以及依次交替地布置的多个溃缩片和隔片。其中,电磁阀固定在溃缩导向盒上,插销被配置成能够插入到插销孔中,溃缩片和隔片具有相同的形状并且在与溃缩导向盒上的插销孔对齐的位置处分别具有与插销孔形状相同的穿孔,插销能够由电磁阀产生的磁力致动并且朝向溃缩片和隔片的穿孔伸展。
