Abstract

The utility model relates to a back frame structure of a backlight module. A rectangular frame body is integrally molded by a metal plate by adopting the stamping technology, the back frame structure is provided with a base plate, wherein the four sides of the base plate are integrally and upwardly connected with a side wall, at least one step-shaped flange part respectively extends outwards and upwards from the each of the four side walls, at least one groove is formed at the flange part on the top surface of one side wall of the four side walls, and at least one section of reverse folding part is respectively, outwardly and downwardly arranged at each flange part on the top surface of each side wall. The back frame structure can be used for replacing the lower iron frame and the plastic frame of the original backlight module and also has the advantages of lower cost and simplified assembly steps.

Description

The back of the body mount structure of backlight module

Technical field

The utility model is relevant a kind of back of the body mount structure, refers to a kind of back of the body mount structure of backlight module especially, and this back of the body mount structure has and reduces cost, and the advantage of simplification number of assembling steps.

Background technology

By LCD is the image display that generally adopts in present electronics or the information industry, and the indispensable important component of LCD is a backlight module, this module comprises LGP, blooming piece, liquid crystal panel, and the light fixture or the light source that are generally fluorescent tube, with as luminous demonstration.

As shown in Figure 1; it is the three-dimensional exploded view of known backlight module; this backlight module 100 comprises chase 101; in addition a glue frame 102 is assembled in this time chase 101 on; then with optical element; for example reflector plate 103, light source group 104, LGP 105, a plurality of blooming piece 106, shading rubber belt 107 and liquid crystal panel 108 are installed in this glue frame 102 fixingly, at last chase 109 on are combined with following chase 101, in order to protect aforesaid optical element.

Therefore, with regard to the backlight module speech of traditional structure, this time chase 101 provides the function of backlight module carrying and structural strength, and glue frame 102 then is in order to put and fixing optical element.Therefore, this time chase 101 is the indispensable critical elements of backlight module with glue frame 102.

So see it with regard to the overall structure of backlight module, optical element is indispensable, therefore if will reduce cost, then this time chase must be designed to possess the storing of original glue frame and the structure and the function of fixing optical element.Therefore, how following chase and the glue frame with backlight module replaces with integrated back of the body mount structure, is the difficult problem that relevant dealer demands urgently overcoming.

The utility model content

The utility model main purpose is to provide a kind of back of the body mount structure of backlight module, and it is the stamp technology of sharp sheet metal and one-body molded, replacing the combination of chase and glue frame down, and has the glue of saving frame mould expense, and the advantage of simplifying number of assembling steps.

For reaching aforesaid purpose, the technological means that the utility model is taked provides a kind of back of the body mount structure of backlight module, its be with sheet metal with the stamp technology, and one-body molded be a rectangle framework, this back of the body mount structure comprises:

One base plate, its four limits one upwards connects a sidewall, this four sidewall respectively outwards and protrude upward the flange part of at least one step shape, wherein the flange part of the end face of a sidewall is vertically offered at least one groove, and each flange part of the end face of this four sidewall is then separately outwards and to having at least one section invayination.

Wherein at least one locating hole is offered in the appropriate location of this base plate.

Wherein four corners of this base plate are offered a locating hole respectively.

Wherein this invayination outer surface is dashed forward and is established at least one button point.

The beneficial effects of the utility model are: have and reduce cost, and the advantage of simplifying number of assembling steps.

Description of drawings

Be further to disclose concrete technology contents of the present utility model, below in conjunction with drawings and Examples describe in detail as after, wherein:

Fig. 1 is the three-dimensional exploded view of known backlight module;

Fig. 2 is the stereogram of the utility model back of the body mount structure;

Fig. 3 is the top view of the utility model back of the body mount structure;

The profile that Fig. 4 and Fig. 5 are intercepted along line A-A and line B-B for Fig. 3.

The specific embodiment

To shown in Figure 5, basically, the utility model back of the body mount structure 200 is for possessing original carrying and structural strength as Fig. 2, is to be to utilize punching press and bending technology and one-body molded with sheet metal with, this back of the body mount structure 200.

Wherein, this back of the body mount structure 200 is a rectangle framework, and its bottom surface has a base plate 201, in order to carry known optical element.And for this back of the body mount structure 200 must be located in diel, be that for example four corners are offered a locating hole 202 respectively with, the appropriate location of this base plate 201, for the insertion of the alignment pin of diel inside, in order to the carrying out of stamp operation.

These base plate 201 4 limit one upwards connect a sidewall 203, and are the storing for optical element, and this four sidewall 203 respectively outwards and protrude upward the flange part 204 of at least one step shape.See also the profile that Fig. 4 and Fig. 5 are intercepted along line A-A and the line B-B of Fig. 3, find out by knowing among the figure, to base plate 201, has multilayer class by the top flange part 204, the accommodation space of three layers of step shape for example is so that from bottom to top bridging and locating for known optical elements such as LGP, blooming piece and liquid crystal panel in regular turn.Please consult Fig. 2 again, wherein the flange part 204 of the end face of a sidewall 203 is vertically offered at least one groove 205, and it is stretching out for flexible printed wiring board (FPC) of the liquid crystal panel of optical element and light source group.

204 of each flange parts of the end face of this four sidewall 203 are separately outwards and to having at least one section invayination 206; the purpose that described invayination 206 is provided with is to replace the thickness of glue frame originally; so that socket-connect, with protection optical element between the two with known last chase.Wherein, each invayination 206 outer surface is dashed forward and is established at least one button point 207, so that the utility model back of the body mount structure 200 and last chase (known do not give graphic) when engaging, the button point 207 of each invayination 205 can be snapped in the button hole that chase is preset, and makes both combinations more firm.

So, via enforcement of the present utility model, the effect that it gained is, back of the body mount structure of the present utility model is one-body molded via the stamp technology by sheet metal, except that possessing carrying originally and structural strength, then can be in the formed a plurality of step shape flange parts in four sidewalls top for the storing and the location of optical element, to replace original glue frame design.This measure, back of the body mount structure of the present utility model can be simplified except that the die cost that can save the glue frame simultaneously, especially descend the operation of the number of assembling steps of chase and glue frame, can be rated as a ware big good structure not seen before.

That the utility model disclosed is a kind of of preferred embodiment, the change of every part or modification and come from technological thought of the present utility model and be have the knack of this technology the people was easy to know by inference, all do not take off claim category of the present utility model.
