[0003] The car ceiling screen is an entertainment device installed on the top of the vehicle for playing multimedia information. It is widely used in medium and large vehicles such as multi-purpose vehicles and station wagons. Users generally use an infrared remote control to control the display screen to flip open or close, and can use the remote control to control the setting interface and adjust the display screen to a comfortable angle through buttons. When in use, the ceiling screen is opened and the display screen is roughly perpendicular to the roof for easy viewing by users. When closed, the ceiling screen rotates and closes, and the display screen roughly fits the roof.

[0004] The opening or closing of the display screen is achieved through an electric transmission mechanism, which usually includes a motor. One end of the display screen is a hinge point. When the motor is started, the other end of the display screen rotates around the hinge point. In order to provide a better viewing angle, the opening angle of the display screen is generally a right angle or an obtuse angle. If the opening angle is too large, it is easy to rotate to the back of the mounting frame. The installation position of the ceiling screen needs to be considered. Therefore, a ceiling screen with a composite motion trajectory is required. Utility Model Content
