The embodiment of the invention provides a collapsible steering column and a vehicle. The collapsible steering column comprises an upper tubular column, a mandrel, a lower tubular column, an adjusting mechanism, a handle and a pin. The position of the collapsible steering column can be adjusted through the handle and the adjusting mechanism, and a toothed plate in the adjusting mechanism is fixed on the outer wall of the upper tubular column through the pin. When a driver collides with the steering wheel, impact force is transmitted to the toothed plate and a clamping hook of the adjusting mechanism through the upper tubular column, when the impact force reaches a threshold value, the pin is cut off, the upper tubular column can collapse towards the front of the vehicle, energy generated by collision is absorbed, and harm to the driver caused by collision is reduced.
本申请实施例提供了一种可溃缩转向管柱及车辆,该可溃缩转向管柱包括上管柱、芯轴、下管柱、调节机构、手柄和销钉,该可溃缩转向管柱可通过手柄和调节机构调节转向管柱的位置,调节机构中的齿板通过销钉固定在上管柱的外壁上,在驾驶员与方向盘发生碰撞时,冲击力通过上管柱传递至调节机构的齿板与卡钩处,在冲击力达到阈值时,销钉被剪断,上管柱能够向车辆前方溃缩,吸收撞击产生的能量,降低碰撞对驾驶员造成的伤害。
