The invention provides a steering column device, a steering system and a vehicle, the steering column device comprises a steering column, a mounting bracket and a cam locking mechanism, an adjusting handle is rotated to drive a first cam to rotate, so that relative rotation is generated between the first cam and a second cam; the protrusions and the grooves on the first cam and the second cam continuously abut against and are meshed with each other, acting force with a certain twisting direction is generated on the second cam and the connecting bolt, the cam locking mechanism and the steering column move along the first mounting plate along with the connecting bolt, and angle adjustment of the steering column is completed. The second cam is provided with a buffer piece, and one end of the buffer piece extends to form a mounting foot and is fixed to the first cam. When reacting force occurs between the first cam and the second cam, the rotation trend of the adjusting handle needs to overcome the friction force of the adjusting handle and the buffering force of the buffering piece to complete rotation, the rotation speed of the adjusting handle is controlled, and the situation that the adjusting handle rebounds and collides with the hands of a driver is avoided.

    本申请提供一种转向管柱装置、转向系统及车辆,其中转向管柱装置包括转向管柱、安装支架及凸轮锁定机构,通过转动调节手柄带动第一凸轮转动,使得第一凸轮和第二凸轮之间产生相对转动,第一凸轮和第二凸轮上的凸起和凹槽不断地进行抵接以及啮合,并对第二凸轮以及连接螺栓产生具有一定扭转方向的作用力,使得凸轮锁定机构和转向管柱随着连接螺栓沿着第一安装板进行移动,完成转向管柱的角度调节。第二凸轮上设有缓冲件,且其一端延伸形成安装脚并固定于第一凸轮。在第一凸轮与第二凸轮之间出现反作用力时,调节手柄的回转趋势需要克服其自身的摩擦力和缓冲件的缓冲力才能完成回转,控制了其回转速度,避免调节手柄反弹撞击到驾驶人员的手。
