Abstract
The present disclosure provides a knob device for vehicle which includes a knob unit and a locking unit. The knob unit includes a rotating cover, a rotary shaft and a motor configured to drive the rotating cover to vibrate. The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and locking teeth formed at a periphery of the main body. The locking tooth includes a first end, a second end and a surface connecting the first end and the second end. A distance between the first end and the central axis of the rotary wheel is greater than a distance between the second end and the central axis. The locking unit further includes a locking pole configured to abut the first end to limit rotation of the rotary wheel clockwise, and an actuator configured to drive the locking pole to move.
