Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted equipment, in particular to a roof rotating screen with a detachable damper. Background Art

[0002] The rotating mechanism of a ceiling-mounted screen is a crucial component in modern automotive design, allowing passengers to adjust their viewing angle by rotating the screen for a better viewing experience. However, most current ceiling-mounted screen rotating mechanisms utilize a motor-driven mechanism, with the motor and damper designed as an integral unit. While this design may meet the needs of certain models, it lacks versatility and is difficult to adapt to the needs of different models and usage scenarios.

[0003] Specifically, this integrated motor and damper design is often inflexible when it comes to the interior space layout, installation location, and rotation angle requirements of different vehicle models. For example, some models may require a larger rotation angle or more precise damping control, and existing integrated designs may not be able to provide such customized services. In addition, this design is not convenient for repair and replacement, as damage to the motor and damper may require replacement of the entire assembly, increasing repair costs and time.
