Turnover device of vehicular display

Abstract

The invention discloses a vehicle-carried display turning device, and relates to a control mechanism for fixing or mounting a display. The invention provides the vehicle display turning device which does not need to add a self-locking mechanism and a braking device, ensures that the whole friction mechanism has no clearance, has damping function on impact suffered by an output shaft, has a small structure and high mechanical efficiency, makes the output shaft bear larger impact and effectively removes free clearance, and has other characteristics of the output shaft. The device is provided with a motor, a double-wormgear worm, a permanent seat, a damping shaft, an upper friction sheet, a lower friction sheet, a damping block, a clutch shaft, a left mounting bracket, a right mounting bracket, a display screen mounting bracket, a mounting rack, a switch shaft, an angle block, and a switch plate. The double-wormgear worm is arranged inside the permanent seat; the double-wormgear worm is provided with a first wormgear worm and a second wormgear worm; a motor gear is engaged with a worm gear; a worm of the second wormgear worm is fixedly connected with a wormgear of the first wormgear worm; a wormgear of the second wormgear worm is connected with a first damping shaft; and an inner hole of the damping block is matched with the output shaft of the wormgear of the second wormgear worm.

Description

technical field [0001] The invention relates to a control mechanism for fixing or placing a display, in particular to an electric turning device for a vehicle-mounted display. Background technique [0002] The application of on-board displays has been gradually promoted, such as setting various displays in the car for entertainment and advertising. In order to ensure the use effect of the vehicle-mounted LCD TV, it is usually necessary to link the vehicle-mounted LCD TV with an electric flip mechanism to control the flip of the LCD TV display screen through the electric flip mechanism. The existing electric turning mechanism usually uses a planetary gear motor as the driving mechanism. Since the planetary gear motor cannot self-lock, it is necessary to add a self-locking mechanism, and the planetary gear motor can withstand the load in a small environment. The impact moment of the electric turning mechanism is small, and the brake device needs to be added, which makes the s...

Problems solved by technology

[0004] The purpose of the present invention is to provide a device that not only does not need to add a self-locking mechanism and a braking device, but also has no gaps in the entire friction mechanism in view of the shortcomings of the existing vehicle-mounted display electric turning mechanism, which has a relatively complex structure, a large volume, and gaps. At the same time, it is a vehicle-mounted display flip device with the characteristics of damping the impact on the output shaft, small structure, high mechanical efficiency, the output shaft can withstand large impacts, and effectively eliminate the free gap of the output shaft.
