Problems solved by technology

However, when the vehicle encounters bumps while driving, the display board and the flat frame will be subject to a sharp acceleration impact. Once this impact is superimposed on the gravity moment of the display board and the flat frame, exceeding the locking torque of the worm gear in the geared motor, it may damage to the worm gear

Embodiment 1

[0042]The application environment of the gravity balance mechanism of the display reversing device of the present invention is: the reversing device has a connecting frame (the connecting frame includes a flat frame 1) and a mounting frame. The tablet frame 1 is connected to the back of the display panel 9 . The installation frame is fixed on the car roof, and its left and right ends are respectively provided with downwardly protruding right lugs and left lugs. On the flat frame 1, a side close to the mounting frame is fixedly installed with a left rotating frame 61, a geared motor and a right rotating frame in sequence.

[0043] The left fixed shaft 62 is sheathed on the left rotating frame 61, and the left end of the left fixed shaft 62 is non-rotatably connected with the left lug of the mounting frame. The output shaft of the reduction motor is coaxially connected to the right fixed shaft that is sheathed on the right rotating frame through a shaft coupling. The right end...

Embodiment 2

[0057] Please check Figure 7 , it differs from Embodiment 1 in that: the right side of the guide block 75 is recessed with an assembly groove 754, and a guide bar 753 is fixed inside the assembly groove 754, and the guide bar 753 is provided with the above-mentioned guide bar. Slot 751.

[0058] Three, embodiment two

[0059] Please check Figure 7 , It differs from Embodiment 1 in that: the eccentric disk 71 is configured as a cam structure, and the cam has a support plane to at least one interval and an axis, and the support plane constitutes the above-mentioned eccentric portion 72'.

Abstract

The invention discloses a gravity balancing mechanism of a displayer turning device. The gravity balancing mechanism comprises a rotary frame part, a rotating part, a sliding part and an elastic mechanism; the rotating part can be rotatably connected to the rotary frame part with the rotating axis being an axis X, an eccentric part is fixedly connected to the rotating part and is eccentrically arranged relative to the axis X, the sliding part is slidably connected to the rotary frame part, and the elastic mechanism is connected with the sliding part and the rotary frame part and can generate elastic force applied to the sliding part, wherein the elastic force makes the sliding part abut against the eccentric part. The gravity balancing mechanism can offset gravitational torque generated bythe gravity of a display panel and a pallet in time to protect a gear motor.

Description

technical field [0001] The invention relates to a component of a vehicle-mounted flat panel display. Background technique [0002] Existing vehicle-mounted flat-panel displays are usually installed on the ceiling in the vehicle. In order to reduce the space in the vehicle, a liquid crystal screen (hereinafter referred to as the display panel) is installed on the flipping device. This overturning device has a mounting bracket fixed on the car roof, and a flat frame installed on the back side of the display panel. The flat shelf of the overturning device is turned up and collected at ordinary times, so that the display surface of the display panel is attached to the ceiling in the car. When in use, the flat frame of the turning device is turned down, so that the display panel is erected. [0003] In a typical overturning device, rotating frames are respectively arranged on the left and right sides of one edge of the flat frame. Each of the two rotating frames is pivotally co...
