[0002] With the continuous improvement of intelligence and passenger experience requirements, the widespread application of display screens has become a major trend. These displays are not only used to provide diversified information services such as navigation, entertainment, and vehicle status monitoring, but also significantly enhance the modernity and technological sense of the cockpit.

[0003] As a product of technological progress, the automatic ceiling screen realizes the automatic lifting of the display screen through the built-in motor and control system. Users can control the expansion and folding of the display screen by simply pressing buttons or voice commands, which greatly facilitates user operation. However, even so, the automatic ceiling screen still relies on the user's active operation to trigger the folding action, which means that in emergency situations such as unstable driving, the display screen may still be in the expanded state, thus failing to completely eliminate the risk of collision.

[0004] Therefore, the display screen still needs to be improved in terms of storage convenience and safety. Especially when the display screen is unfolded, its protruding position and unpredictable collision risk have become problems that need to be solved urgently.

[0005] Therefore, the present application studies a ceiling screen system that can reduce the risk of collision in emergency situations such as unstable driving. Utility Model Content
