The invention relates to the field of vehicle-mounted display screens, in particular to a high-stability vehicle-mounted display screen. Comprising a mounting shell, a rotating column and a display screen, the rotating column is rotationally arranged on the mounting shell, the display screen is connected to the rotating column, a first rotating shaft and a second rotating shaft are rotationally arranged in the mounting shell, a driving mechanism is mounted on the mounting shell and used for driving the first rotating shaft to rotate, and a transmission mechanism is mounted between the first rotating shaft and the second rotating shaft; the transmission mechanism is used for transmission between the first rotating shaft and the second rotating shaft. Through the conical surface design of the rubber sleeve and the outer wall of the rotating column, when the contact surface of the rubber sleeve becomes small due to abrasion, the second spring can automatically push the rubber sleeve to move, so that the inner wall of the rubber sleeve clings to the outer wall of the rotating column again, and the service life of the rubber sleeve is prolonged; and it is ensured that the rubber sleeve can still be in close contact with the rotating column after being used for a long time, screen shaking caused by gear gaps is effectively reduced, and the stability of the display screen is improved.
本发明涉及车载显示屏领域,尤其涉及一种高稳定式车载显示屏。包括有安装壳、旋转柱和显示屏,安装壳上转动设置有旋转柱,旋转柱上连接有显示屏,安装壳内转动设置有第一转轴和第二转轴,安装壳上安装有驱动机构,驱动机构用于驱动第一转轴进行旋转,第一转轴与第二转轴之间安装有传动机构,传动机构用于第一转轴与第二转轴之间进行传动。本发明通过橡胶套与旋转柱外壁的锥面设计,当橡胶套因磨损导致接触面变小时,第二弹簧会自动推动橡胶套移动,使其内壁再次紧贴旋转柱外壁,从而延长了橡胶套的使用寿命,以及确保橡胶套在长时间使用后仍能保持与旋转柱的紧密接触,有效减少了因齿轮间隙引起的屏幕晃动,提高了显示屏的稳定性。
