Fixing the display screen on the dashboard of the car is a more fixed method, but the display screen takes up a lot of space, which conflicts with more and more other automotive electronic components in terms of space occupation; moreover, the The display screen is fixed on the instrument panel so that it is perpendicular to the direction of human viewing angle, which is not conducive to viewing

In addition, the current display lifting device does not have anti-pinch and self-protection functions

If the driver does not notice that the occupant's hand or object is placed in the base assembly of the center display on the instrument panel, it is easy to be caught by the lowering display

In addition, the display screen has been exposed for a long time and lacks protection
