Abstract
The invention discloses a steering column locking mechanism which comprises a rotary handle, a first cam connected to the end portion of the rotary handle, a second cam matched with the first cam and a third cam in linkage with the first cam and further comprises an elastic sheet connected with the second cam, tightly attached to the outer wall of the first cam and used for providing friction damping for the rotating first cam. The elastic sheet is additionally arranged and connected to an immobile piece, namely the second cam, and the elastic sheet is tightly attached to the outer wall of the first cam. Therefore, when rotating relative to the second cam, the first cam can bear the friction damping effect of the elastic sheet so that it can be guaranteed that the rotating force required by the rotary handle is even and is continuously increased, and the adjusting comfort feeling of the steering column locking mechanism is improved. In addition, when vibration is generated between the first cam and the second cam, the elastic sheet can absorb vibration, so that the stability of a steering system is guaranteed, and abnormal sounds are reduced.
