[0002] With the development of the automotive industry, drivers' demands for vehicle comfort and safety are increasing. The steering column, as a crucial component of a car, not only affects driving convenience but also directly impacts driving safety. Traditional steering column adjustment mechanisms typically rely on manual adjustment, which is both time-consuming and labor-intensive. Especially in the event of a collision, this manual adjustment method can lead to the steering column failing to lock in time, increasing the risk to the driver. Therefore, the research and application of automatic locking automotive steering column adjustment mechanisms have become particularly important.

[0003] Most existing steering column adjustment mechanisms rely on mechanical structures. While these can improve adjustment efficiency to some extent, they typically lack automatic locking capabilities, and are particularly inadequate for safety during collisions. In recent years, with the increasing popularity of electric and hybrid vehicles, the demands for intelligence and safety in vehicles have further increased, rendering traditional mechanical steering column adjustments insufficient for modern vehicle needs.
