VEHICLE DISPLAY DEVICE AND VEHICLE

The present disclosure relates to a vehicle-mounted display screen device and a vehicle. The vehicle-mounted display screen device includes a display screen, a motor and a transmission system. The motor drives the display screen to rotate through the transmission system. The transmission system includes a first shaft, a second shaft, a first semi-clutch, a second semi-clutch and an elastic component, the first shaft and the second shaft are coaxially arranged, the first semi-clutch is slidably sleeved on the first shaft axially, the second semi-clutch is connected to the second shaft, a first tooth is formed on an end surface of the first semi-clutch facing the second semi-clutch, a second tooth is formed on an end surface of the second semi-clutch facing the first semi-clutch, and the elastic component applies axial elastic force to the first semi-clutch to enable the first tooth and the second tooth to be engaged. Through the mode, on the one hand, switching between a horizontal screen and a vertical screen can be realized, and on the other hand, power transmission can be interrupted in time when an overload condition of the system occurs so as to prevent the motor and the transmission system from being damaged.
