The invention provides a steering column collapse energy-absorbing device and a vehicle, and relates to the field of steering column collapse technology.The steering column collapse energy-absorbing device comprises a first steering shaft, a column protection shell, a second steering shaft and an electromagnetic mechanism; the electromagnetic mechanism is arranged between the first steering shaft and the second steering shaft, and the electromagnetic mechanism is used for adjusting the crushing force between the first steering shaft and the second steering shaft according to the principle that like poles of a first electromagnet and a second electromagnet repel each other, so that the crushing force between the first steering shaft and the second steering shaft is adjustable. Therefore, different crushing forces required by different drivers and different steering wheel positions can be adapted. In this way, the problem that the predesigned fixed value crushing force of an existing steering column cannot meet the requirements of different posture characteristics of different drivers for the crushing force is solved.
本申请提供一种转向管柱溃缩吸能装置及车辆,涉及转向管柱压溃技术的领域,本申请提供的管柱溃缩吸能装置包括第一转向轴、管柱护壳、第二转向轴和电磁机构;电磁机构设置在第一转向轴与第二转向轴之间,电磁机构通过利用第一电磁铁和第二电磁铁同极相斥的原理,用于调节第一转向轴和第二转向轴之间的压溃力,使得第一转向轴与第二转向轴之间的压溃力为可调节的,以此适配不同驾驶员和不同方向盘位置所需的不同压溃力。这样,解决现有转向管柱预先设计的固定值压溃力无法满足不同驾驶员的不同体态特征对压溃力的需求的问题。
