Description

A kind of good and reliable display module of heat dispersion

Technical field

This utility model is related to a kind of display module, the good and reliable display module of more particularly, to a kind of heat dispersion.

Background technology

Display module generally comprises the backboard being fixed together, center, lamp bar, backlight group, liquid-crystalline glasses, and center is mainly For fixing backlight group, also act as the effect carrying liquid-crystalline glasses, the effect therefore in module is extremely important simultaneously.As Fig. 1 Shown, traditional display module adopts plastic cement center, and it includes cubic framework a, up extends from described four directions framework four side One circle frame b, this frame forms the space for supporting liquid-crystalline glasses together with cubic framework, and this plastic cement center has following lacking Point: one, the heat conductivility of plastic cement is bad, localized hyperthermia can cause lamp bar glue to lose efficacy thus making under existing process conditions Become lamp bar to come off, cause product bad；2nd, poor reliability, because the chance ratio that display screen is used for rail transportation projects is larger, rail Product occurs vibration and impact in use for road traffic, and therefore the rigidity of product construction and stability are very important Product quality, and plastic material mechanical strength is not high, therefore easily plastic deformation and causes getting loose of product；3rd, not ring Protect, no matter being to produce or reclaim all environment can have been polluted；4th, production cost is high, because the characteristic of plastic cement, when demand is big During size center, in order to reach predetermined function it is necessary to increase the integral thickness of described frame, and produce complex-shaped thereon Buckle c, position of bone d, avoid hole e etc., and these buckles, the position of bone are difficult to complete using general processing technique it is necessary to by Special auxiliary mould molding, thus causing production cost high, and the avoidance hole site of each product is different, thus needing not Same mould, further increases production cost.

Utility model content

The purpose of this utility model is to provide a kind of heat dispersion good and reliable display module.

For achieving the above object, this utility model be the technical scheme is that

A kind of good and reliable display module of heat dispersion, including a sub- black aluminium alloy center, described Asia black aluminum Alloy center includes a quadro frame, is provided with multiple spaced avoidance holes, the left and right sides on front side of described quadro frame Side be provided with screw hole on left and right directions, and the every side in the described quadro frame left and right sides is all up prolonged from outside upper surface Stretch and be provided with positioning baffle, the described quadro frame left and right sides is provided with the hollow hole on above-below direction inside positioning baffle.

The every side in the described quadro frame left and right sides is up extended all from outside upper surface two spaced positioning Baffle plate.

The beneficial effects of the utility model are: because this utility model display module employs sub- black aluminium alloy center, Sub- black aluminium alloy center perfect heat-dissipating, high mechanical strength, so as to increase the service life of lamp bar, dependable performance；And Aluminium alloy center processing technique is simple, is independent of mould, and also removes the baroque position of bone, buckle etc., thus reducing Production cost.

Specific embodiment

As shown in Fig. 2,3,4,5, the good and reliable display module of this utility model heat dispersion includes a sub- black aluminum Alloy center 1, described Asia black aluminium alloy center 1 includes a quadro frame 11, is provided with multiple on front side of described quadro frame 11 Spaced avoidance hole 12, the side of the left and right sides is provided with the screw hole 13 on left and right directions, and described quadro frame The every side in 11 left and right sides all from outside upper surface up be extended have positioning baffle 14, described quadro frame 11 left and right sides in It is provided with the hollow hole 15 on above-below direction, described hollow hole 15 is conducive to overall stress equilibrium inside positioning baffle 14.

In the present embodiment, preferably, the every side in described quadro frame 11 left and right sides all up extends from outside upper surface It is provided with two spaced positioning baffles 14.

In assembling, the aluminium alloy center 1 of this utility model display module is connected to backboard by modes such as screws, and aluminum Alloy center 1 lower end is pressed in backlight group, and LCDs are placed in aluminium alloy center 1 upper end, and by the positioning of the left and right sides Baffle plate 14 is spacing, i other words, the institute that the sub- black aluminium alloy center 1 of this utility model display module has traditional center is active Energy.

In sum, because aluminium alloy than plastic cement perfect heat-dissipating, thus center of the present utility model can be quickly by lamp Produced by bar, heat sheds, and improves the service life of lamp holder；Additionally, aluminium alloy amount of plastic deformation very little and rigidity is big, I.e. mechanical performance is strong, thus can guarantee that the reliability of product；And aluminum alloy materials in process of production waste gas discharge seldom, with When the also more convenient processing in the secondary utilization of waste, thus environmental protection；Furthermore, metalwork is little to the dependency of mould, permissible The section bar (shape extrusion can carry out stretching extrusion molding) wanted is made in die sinking by mould, then carries out the later stage on section bar Processing, such as open screw hole 13 etc., the length of section bar can be accomplished the length wanted and without being spliced, and is used for section bar The mould of stretching extruding is also very cheap, along with aluminium alloy center does avoidance hole 12 and processes by being squeezed into after section bar, no Limited by mould, can accomplish that a mould is general, and the center of this utility model display module also removes complex-shaped bone Position, buckle part, thus reducing the cost of product, improve the competitiveness of product；Finally, because aluminium alloy is silvery white in color, Therefore optically can there is reflective situation, cause product the situation of surrounding white line to occur it is therefore desirable to carry out aluminium alloy Blackening process, blacks and is divided into Ya Hei and light black, and light is black or understands reflective, causes optics bad, therefore adopts sub- black technology, in inciting somebody to action Sub- black made by frame, can prevent reflective.

In the description of above-mentioned orientation, with the positioning all around in Fig. 2 all around.
