The invention discloses a safety protection device of an automobile steering wheel, relates to the technical field of safety protection of automobile steering wheels, and aims to solve the problems that a supporting column of an existing steering wheel only uses a section of spring for buffering, the elastic coefficient of the supporting column is fixed, if the elastic coefficient of the supporting column is large, the supporting column is difficult to contract for energy storage, and the overhard spring still causes certain impact to a driver. In order to solve the problems that in the prior art, when a steering wheel is collided violently, if the elastic coefficient of a spring is small, energy capable of being absorbed and buffered by the spring is limited, and the buffering effect is insufficient when the steering wheel is collided violently, three layers of buffering protection mechanisms are arranged in a steering wheel supporting column in total, and the first layer of spring is small in elastic coefficient and can deform in time for buffering; the second layer enables the steering wheel to be bent and buffered in the direction in which a driver puts over, the contact area between the steering wheel and the driver is increased, hurt to arms of the driver is further reduced, the springs with the large elastic coefficient are arranged on the bottommost layer, and too large impact force can be conveniently absorbed and buffered.

    本发明公开了一种汽车方向盘的安全防护装置,涉及汽车方向盘安全防护技术领域,现有的方向盘的支撑柱仅使用一截弹簧进行缓冲,其弹性系数是固定的,如果其弹性系数较大,难以收缩储能,过硬的弹簧仍会对驾驶员造成一定的冲击,但如果弹簧弹性系数较小,其能够吸收并缓存的能量有限,在受到猛烈撞击时,其缓冲效果不足的问题,本发明在方向盘支撑柱中总共设置有三层缓冲防护机构,第一层弹簧弹性系数较小,能够及时产生形变进行缓冲,第二层使方向盘能够顺着驾驶员扑过来的方向进行弯折缓冲,增加方向盘与驾驶员之间的接触面积,进而减小对驾驶员手臂处的伤害,最底层设置有弹性系数较大的弹簧,便于能够对过大的冲击力进行吸收缓冲。
