Mounting structure of automobile instrument liquid crystal screen

Abstract

The invention provides a mounting structure of an automobile instrument liquid crystal screen. The mounting structure comprises a front shell, a rear shell and a connecting plate; the front shell andthe rear shell are connected through the connecting plate; glass is installed on the outer side of the front shell, and the liquid crystal screen is arranged between the front shell and the connectingplate; the front side of the liquid crystal screen is attached to the periphery of the glass through a shockproof gasket on the periphery; the rear side of the liquid crystal screen is attached to the connecting plate through a shockproof gasket, and screw holes are formed in the rear shell; a flexible arc-shaped plate is arranged on the periphery of nut posts opposite to the screw holes; the arc-shaped plate is connected with the connecting plate, and screws penetrate through the screw holes and are screwed into the nut posts, so that the rear shell and the connecting plate are connected. The flexible arc-shaped plate absorbs most vibration transmitted to the rear shell by an automobile, small part of vibration is transmitted to the connecting plate from the rear shell, and the shockproof gasket on the connecting plate has a good buffering effect, so that the vibration and impact force transmitted by the rear shell to the rear side of the screen are further buffered, and the situation that the liquid crystal screen is not uniform in the dark state due to mutual extrusion of the liquid crystal screen and the glass is greatly reduced.

Description

technical field [0001] The invention relates to a liquid crystal instrument panel of an automobile, in particular to an installation structure of an automobile instrument liquid crystal screen. Background technique [0002] The LCD instrument panel is a device that displays vehicle driving information to the driver. It replaces the traditional mechanical instrument panel with a whole LCD screen, cancels the traditional physical pointer, and displays all the driving information through the LCD screen. Due to the poor ability of the LCD screen to resist stress, it is easy to be scratched, so in order to protect the LCD screen, a piece of glass is provided on the surface of the LCD screen to protect the LCD screen, and the glass and the LCD screen are fully bonded by optical glue. Due to its hard texture, glass has a better ability to resist stress, which can prevent the front of the LCD screen from being scratched or scratched. [0003] However, the LCD screen is very sensiti...

Problems solved by technology

[0003] However, the LCD screen is very sensitive to pressure. When the LCD screen is slightly pressed, the phenomenon of "uneven dark state" will appear. The larger the screen size, the more obvious this phenomenon will be, which seriously affects the display effect of the screen.

The vibration generated by the driving of the car is transmitted to the LCD screen of the car instrument, causing the LCD screen to squeeze the glass irregularly with the vibration, and even if there is no external pressure, it is prone to "uneven dark state"; because the glass fixed to the shell structure of the instrument area The liquid crystal screen in the instrument area is easy to be shaken and relatively squeezed during the driving process of the car. In other words, the existing installation structure of the liquid crystal screen of the car instrument makes the liquid crystal screen equipped with glass more sensitive to pressure and more likely to appear " The phenomenon of unevenness in the dark state
