Description

Floated display screen and mounting structure thereof

Technical Field

The utility model relates to a accuse display screen field in the on-vehicle especially relates to a floated display screen and mounting structure thereof.

Background

At present, as a central control display screen which is most closely interacted with a user, screen enlargement and full touch screen display become design directions of the current, and the central control display screen is gradually enlarged. At present, the accuse display screen is mostly adopted 8 cun, 9 cun, 10.4 cun etc. relatively little liquid crystal display, because the liquid crystal display size is less, liquid crystal display weight is lighter, and the inside assembly structure of well accuse display screen all adopts touch-sensitive screen and liquid crystal display to laminate the back completely, installs through following two kinds of assembly methods:

assembly mode (1): the touch screen back glue is adhered to the plastic front shell, local points are selected between the liquid crystal display screen and the plastic front shell for glue dispensing and fixing, and then the liquid crystal display screen is directly installed on the instrument board of the center console in a suspension or embedded mode after other parts such as an upper panel bracket, a PCB (printed circuit board), a plastic rear shell and the like are assembled.

Assembly mode (2): the touch screen gum is adhered to the plastic front shell, a plurality of screw columns are riveted to the back face of the liquid crystal display screen and are fixed with the plastic front shell in a locking mode through screws, and the touch screen gum is directly installed on a center console instrument board in a suspension or embedded mode after other parts such as an upper panel support, a PCB (printed circuit board) and a plastic rear shell are assembled.

These two prior art arrangements are only suitable for relatively small sized, lightweight center control displays, and for those over 15 "oversized suspended center control displays, because the overall dimension of the liquid crystal display screen is larger and the weight is heavier, the weight of the whole central control display screen is heavier, if the internal structure of the central control display screen adopts the existing assembly mode (1), namely, after the touch screen and the liquid crystal display are completely laminated, the touch screen is adhered with the plastic front shell through the back glue of the touch screen, and local points are selected between the liquid crystal display and the plastic shell for glue dispensing and fixing, the adhesive force of the back glue of the touch screen and the adhesive force of the glue between the liquid crystal display screen and the plastic front shell can not bear the total weight of the liquid crystal display screen and the touch screen at all by 15.6 inches, therefore, the liquid crystal display screen and the touch screen are easily separated from the plastic front shell in a degumming way under a high-temperature or vibration environment.

If well accuse display screen inner structure adopts current assembly (2), touch-sensitive screen and the full laminating back of liquid crystal display promptly, paste through the touch-sensitive screen gum and the preceding shell of plastic, it is fixed that several screw posts of riveting pass through screw locking with the preceding shell of plastic on the liquid crystal display back, because the preceding shell overall dimension of plastic is great, whole deflection is also great, the deformation extrusion or the dragging of shell before will receiving the plastic of the liquid crystal display riveting screw post department of being connected fixedly before with the plastic, thereby the liquid crystal glass part that leads to liquid crystal display receives the external stress influence to change colors, the display effect of accuse display screen in the influence, the shell also can be dragged by liquid crystal display before the plastic simultaneously and tear. And the large and heavy central control display screen is directly arranged on the central control instrument board in a suspension mode, the whole weight of the central control display screen is concentrated on the central control instrument board, the central control instrument board is prone to being torn or collapsed, particularly, the central control display screen shakes seriously in the driving process of an automobile, normal use of a client is affected, and meanwhile, if the strength of the central control display screen mounting bracket is not enough, the central control display screen mounting bracket also deforms or tears.
