Compared with the prior art, the backlight module has the advantage that space of COF (chip on film) is guaranteed through a structure of a protruding portion of the back plate, the recessed clamping hook of the front frame and the first folded edge and the second folded edge of the clamping hook.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of backlight module.
Background technology
Along with the fast development of semiconductor technology especially lcd technology, the liquid crystal display that volume is little, lightweight, viewing area is large is more and more subject to user's favor, meanwhile, also more strict for the reliability requirement of backlight module in liquid crystal display.In existing backlight module, mainly comprise a front frame, a backboard and be positioned at the plastic cement frame of this back plate edges.At present; in NB (Notebook) or PAD class light inlet side structure, by the double-fold of panel beating, abdicate the bending space of COF (Chip On Film, membrane of flip chip); at the side of backboard, by the thick space of avoiding COF of meat of glue frame, note attached adhesive tape sheet in outside is protected.But existing method is not enough to the protection of COF, the commonality of mould is not strong simultaneously.
Therefore, be necessary prior art to do further improvement

As preferred embodiment of the utility model, described snap fit is that the thickness of described snap fit equals the twice of described front frame thickness to portion's depression in described front frame.
As preferred embodiment of the utility model, the size of described the first flanging equals the size of described the second flanging.
As preferred embodiment of the utility model, described the first flanging, the second flanging and connecting portion are formed in one.
As preferred embodiment of the utility model, described connecting portion is semi-cylindrical.
As preferred embodiment of the utility model, the radius of described half-terete connecting portion equals the thickness of described the first flanging or the second flanging.
As preferred embodiment of the utility model, the quantity of described snap fit is at least two, and it is positioned on a side of described front frame.
As preferred embodiment of the utility model, the quantity of described snap fit is two, and it lays respectively at the two ends of a side of described front frame.
As preferred embodiment of the utility model, a side of described front frame and described snap fit adjacent offer perforate.
As preferred embodiment of the utility model, on described backboard, be provided with jut, described jut fastens by described perforate and described snap fit.
The beneficial effects of the utility model: compared with prior art, the utility model guarantees the space of COF by the jut of backboard and the first flanging of the depression snap fit of front frame and snap fit and the structure of the second flanging.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.Wherein:
Fig. 1 is the coupler construction schematic diagram of the front frame of the utility model backlight module;
Fig. 2 is the structural representation of looking up of Fig. 1;
Fig. 3 is the structural representation of snap fit in Fig. 1.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Alleged " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model herein.Different local in this manual " in one embodiment " that occur not all refer to same embodiment, neither be independent or the embodiment mutually exclusive with other embodiment optionally.
Refer to Fig. 1 to Fig. 3, Fig. 1 is the coupler construction schematic diagram of the front frame of the utility model backlight module; Fig. 2 is the structural representation of looking up of Fig. 1; Fig. 3 is the structural representation of snap fit in Fig. 1.A kind of backlight module of the utility model, it comprises a backboard (not shown) and the front frame 1 fastening with described backboard.
One side of described front frame 1 is provided with snap fit 11.In order to guarantee the space of COF, described snap fit 11 is to 1 li of portion's depression of described front frame.The thickness of described snap fit 11 equals the twice of described front frame thickness.In the utility model, described snap fit 11 degree of depth that 1 li of portion of frame caves in forward is not limited, can determine according to actual conditions.Described snap fit 1 has the connecting portion 113 that has the first flanging 111, the second flanging 112 and be positioned at described the first flanging 111 and the second flanging 112 ends.Wherein, described the second flanging 112 is positioned at the inner side of described front frame.The size of described the first flanging 111 equals the size of described the second flanging 112.Described connecting portion 113 is semi-cylindrical, and the radius of described half-terete connecting portion 113 equals the thickness of described the first flanging 111 or the second flanging 112.In this embodiment, described the first flanging 111, described the second flanging 112 are formed in one with connecting portion 113.In other embodiments, the molding mode of described the first flanging 111, the second flanging 112 and connecting portion 113 is not limit, can be determined as the case may be.
