The specific embodiment
General idea of the present utility model is: carry out architecture advances by metal frame in backlight module and glue frame, be specially in the outside of glue frame side and be provided with at least one projection, the opening that arranges on the main and metal frame of this projection fastens, so not only make on the glue frame projection effective engaging scope obtain increasing, solved the not firm problem of assembling that causes because of glue frame or metal frame scale error; And assembling intensity and the assembly yield of whole backlight module have been improved.For making technical solutions of the utility model and advantage clearer, by reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment.
Metal frame in the present embodiment and glue frame can be for containing the structure of three any numbers of sides more than the side, but in order to make explanation clearer and easy, in the present embodiment, adopt quadrangle metal frame and quadrangle glue frame that the application's technical scheme is described, please refer to Fig. 3, Fig. 4 and Fig. 5, respectively be provided with three projections 411 at glue frame 41 a pair of on than long side, respectively be provided with two projections 411 on the short opposite side, and the projection on each limit 411 is evenly distributed along the length direction of its place side.The shape of projection 411 then can be any shape, as long as establish the opening 421 that is complementary with it at metal frame 42 correspondence positions.More excellent, the upper surface of projection is horizontal surface; Lower surface and its place side form the angle towards upper surface, and described angle is acute angle, and is more excellent, and the scope of this angle between 60 degree time, can reach good engaging effect at 30 degree; It is parallel with its place side with the front surface of lower surface to connect upper surface; Two sides are vertical with its place side.Such setting not only can make glue frame 41 and the assembling of metal frame 42 have adjustable build-up tolerance scope, and the inclined design of lower surface, can make glue frame 41 more firm with engaging of metal frame 42, also easier assembling, increase the stability of assembling, also increased the structural strength of glue frame 41 simultaneously.In the present embodiment, the projection 411 on the glue frame 41 in being snapped into metal frame opening 421 after, also certain activity space should be arranged, so that glue frame 41 all has certain scale error space on all directions.In the present embodiment, it is a kind of more excellent set-up mode that projection 411 all is set on each limit of glue frame 41, and it can also only arrange in a pair of non-conterminous side outside, such as a pair of long limit or pair of short edges.And the hop count of projection 411 also is not limited in two sections or three sections, and the projection 411 of hop count can both realize making among the application backlight module to assemble firmly purpose arbitrarily.
Please refer to Fig. 6-Fig. 9, in the present embodiment, on the glue frame 41 sides outside gulde edge 412 spacing with metal frame 42 interior flanging 422 backstops can also be set, more excellent, this gulde edge 412 can be arranged between two adjacent projections 411, and coupled.This gulde edge 412 can be various shape, as long as it can engage with interior flanging 422.More excellent, gulde edge 412 can be the strip limit, its upper surface is horizontal end face, in order to gulde edge Maximum Contact area is engaged with interior flanging 422.Same, in order to keep certain scale error space, should stay between this gulde edge 412 and the interior flanging 422 and establish certain gap.Gulde edge 412 in the present embodiment is except can auxiliary projection 411 engaging, because it is one-body molded with glue frame 41, projection 411, it can also increase the structural strength of glue frame 41, thus the bulk strength of increase backlight module.
In the present embodiment, except can between two projections 411 on glue frame 41 each side, continuous gulde edge 412 being set, reaching best retention effect and strengthen outside the adhesive frame structure; Through test, can also projection 411 and continuous gulde edge 412 be set an a pair of opposite side (being non-conterminous side) at glue frame 41, get final product and only need to arrange equally distributed protruding 411 on an other opposite side, such setting also can reach preferably structural strength and retention effect.
In the present embodiment, also provide a kind of liquid crystal indicator, it comprises: the backlight module in display panels, control circuit and above-described embodiment.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
