The invention relates to a vehicle-mounted display turnover driving device which comprises a gear box and an output shaft arranged on the gear box, and an output shaft driving mechanism driven by a first motor and an output shaft holding mechanism driven by a second motor are arranged in the gear box. The output shaft driving mechanism comprises a first worm arranged on an output shaft of the first motor, a first gear meshed with the first worm, an anti-locking gear and a second gear arranged on the output shaft and meshed with the anti-locking gear, and a first intermediate transmission gear is arranged between the first gear and the anti-locking gear. The gear has the advantages that the gear can be prevented from being damaged; according to the invention, shaking of the display caused by a gear gap during vehicle driving can be eliminated, damage to the first motor when the display is turned over manually is avoided, slipping can be generated under a certain torque when the display is touched, and the safety of people is guaranteed.
本发明为一种车载显示器翻转驱动装置,包括齿轮箱和设置在齿轮箱上的输出轴,所述齿轮箱中设有由第一电机驱动的输出轴驱动机构和由第二电机驱动的输出轴抱紧机构,所述输出轴驱动机构包括设置在第一电机输出轴上的第一蜗杆、与第一蜗杆啮合的第一齿轮、防锁死齿轮和设置在所述输出轴上且与防锁死齿轮相啮合的第二齿轮,所述第一齿轮和防锁死齿轮之间设置有第一中间传动齿轮。本发明的优点是:能够避免齿轮受损;能够消除显示器在车辆行驶中齿轮间隙产生的抖动,避免人为翻转显示器时对第一电机的损坏,并在碰到显示器时能在一定力矩下产生打滑,保证人的安全。
