Knob device and vehicle

The invention relates to the technical field of rotary knobs, in particular to a rotary knob device and a vehicle. The knob device comprises a fixing seat, a rotating assembly, a first bearing part, a second bearing part, a friction part, a first driving part and a second driving part. When the rotating assembly rotates in response to the external force, the second bearing piece can move in the direction close to the friction piece under the driving of the second driving piece and apply acting force to the friction piece, so that friction force for preventing the second bearing piece from moving in the circumferential direction of the fixing base can be generated between the second bearing piece and the friction piece. When the first bearing part rotates by a preset angle, the first driving part can apply continuous acting force to the rotating assembly for preset time, and the rotating assembly can move in the direction close to the fixing base under driving of the first driving part and compress the first e
