About addressing other technologies content, characteristics and effect before the present invention, in the following detailed description that cooperates with reference to graphic embodiment, can clearly present.The direction term of mentioning in following examples such as: upper and lower, left and right, front or rear etc., only is the direction with reference to annexed drawings.Therefore, the direction term of use is to illustrate not to be to limit the present invention.
Fig. 1 is the combined-type backing plate schematic diagram that is used for backlight module according to one embodiment of the invention.As shown in Figure 1, combined-type backing plate 10 comprises one first backboard block 12a, one second backboard block 14 and one the 3rd backboard block 12b, the first backboard block 12a and the 3rd backboard block 12b connect respectively the second backboard block 14 relative a first side P and a second side Q, and form an inside surface 11.In an embodiment, the light-emitting component (not illustrating) of backlight module can be arranged at the light-emitting component setting area A among Fig. 1.In the present embodiment, the first backboard block 12a and the 3rd backboard block 12b are consisted of by the aluminium extruded type material that can implement extrusion modling processing, for example model is aluminium or the aluminum alloy materials of AL1000, AL3000 or AL6000 series, and the second backboard block 14 is consisted of by steel, for example can use inferior plumbous galvanized steel plain sheet (SECC) material of electrolysis.The inferior plumbous galvanized steel plain sheet of electrolysis can be corrosion-resistant, mechanism's intensity strong and price is cheap than aluminum alloy materials, but shortcoming is that heat conductivility is relatively poor.Therefore, design by the present embodiment, be provided with the backboard block 12a of light-emitting component (thermal source), 12b makes aluminium or the aluminum alloy materials of the high thermal conduction characteristic of apparatus, and because the spread length of heat is limited, the material in centre position there is no impact to integral heat sink, so the second middle backboard block 14 can adopt the relatively poor but inferior plumbous galvanized steel plain sheet (SECC) of lower-cost electrolysis of heat conductivility, and can save manufacturing cost but can obviously not affect the radiating effect of backboard integral body, and can increase the structural strength of combined-type backing plate 10 and not yielding under high temperature.Therefore, the mode that the present embodiment utilizes different backboard blocks to engage is except can providing above-mentioned advantage, because of the size less of each backboard block, therefore in making or process comparatively simple and easy in the processing and not needing large-scale machining machine and tool.
Fig. 2 and Fig. 3 are schematic diagram, show the mode of splicing different backboard blocks according to one embodiment of the invention.As shown in Figure 2, in an embodiment, the first backboard block 12a of unlike material (the 3rd backboard block 12b) can rivet mutually with the second backboard block 14.The second backboard block 14 is in being formed with a kink 16 with the first backboard block 12a or the 3rd backboard block 12b junction, be riveted to the first backboard block 12a (the 3rd backboard block 12b) by the kink 16 with the second backboard block 14, can connect different backboard blocks and form combined-type backing plate 10.In addition, the second backboard block 14 also can have several support portions 15, and the second backboard block 14 is supported in support portion 15.Moreover as shown in Figure 3, an aluminum strip 18 can be riveted on the side that the first backboard block 12a, the second backboard block 14, the 3rd backboard block 12b link to each other to improve mechanism's intensity of splicing place.In an embodiment, as shown in Figure 4, aluminum strip 18 can form at least one notch 18a engaging a light guide plate (not shown), and the quantity of notch 18a and position can change arbitrarily on demand.
As shown in Figure 5, in an embodiment, subregion R vicinity or the superimposed light-emitting component 22 of the first backboard block 12a, and subregion R has a thickness thicker with respect to other zone of the first backboard block 12a, and the integral thickness of the first backboard block 12a court successively decreases away from the direction of light-emitting component 22, but so the first backboard block 12a Uniform Dispersion heat.In addition, formed a draw-in groove 26 clips one glue frame 28 because the thickness of subregion R is thicker, and because glue frame 28 clips are in draw-in groove 26, but not be covered in side outside the first backboard block 12a, therefore the outside of the first backboard block 12a can be directly and air carry out heat interchange, increased area of dissipation and can improve radiating efficiency.In addition, as shown in Figure 6, in an embodiment, the bottom side of the first backboard block 12a (the 3rd backboard block 12b) subregion R that thickness is thicker, roughly be positioned on the same level with the bottom side of the support portion 15 of the second backboard block 14, to improve support strength and inside surface 11 (such as Fig. 1) flatness of combined-type backing plate 10.
Certainly, the above-mentioned usefulness of utilizing three backboard blocks only to splice and combine as illustration does not limit fully, the visual actual demand of the quantity of backboard block, material and connected mode is changed, and for example also can only use the light path design of the first backboard block 12a and the second backboard block 14 and the single-sided illumination of arranging in pairs or groups.
The above, only for the present invention's preferred embodiment, when the scope that can not limit with this invention process, the simple equivalence of namely generally being done according to the present patent application claim and invention description content changes and modifies, and all still belongs in the scope that patent of the present invention contains.Arbitrary embodiment of the present invention or claim must not reached whole purposes or advantage or the characteristics that the present invention discloses in addition.
