Abstract
The application discloses a low-noise electric rotating mechanism for a car screen, which comprises a seat body, a car screen, a multi-stage telescopic rod assembly, a screw transmission assembly, a spherical hinge pitching assembly, a rotating drive assembly, a gravity pendulum assembly, a support plate and a supporting plate. The mechanism can realize the front and back telescoping, pitching adjustment and horizontal rotation of the car screen, adapt to the visual angle requirements of different driving and riding scenes, effectively reduce the running noise through the matched mute structure, and guarantee the quietness in the car. The gravity pendulum assembly realizes the pure mechanical detection of the screen sagging based on the gravity principle, can accurately sense the posture deviation of the screen without an electronic sensor, and has simple structure and high reliability. When the screen sagging exceeds the set angle, the connected switch can be automatically triggered, the posture correction is completed through the linkage drive mechanism, the sagging problem of the screen after long-term use is solved through the self-locking structure, the stable posture of the screen is maintained, and the service life of the mechanism is prolonged.
