Specific embodiment
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model carry out into
One step detailed description.
Embodiment one
Refering to fig. 1 and it is small-sized to be mainly used as Vehicular display device, tablet computer etc. for Fig. 2, a kind of small-sized side entrance back module
Show equipment.Backlight module includes iron-clad 1, lamp bar 2, diaphragm structure 3 and glue frame 4, and the side in iron-clad 1 is arranged in the lamp bar 2
On face, lamp bar 2 generally uses the side entering type lamp bar of FPC and LED welding production, and the installation of lamp bar 2 can pass through bond plies
Bonding, thereby may be ensured that the heat dissipation of LED.The glue frame 4 is mounted on iron-clad 1, preferably by buckle structure and double-sided adhesive 15
It is fixedly connected jointly, buckle structure plays integrally fixed effect, and double-sided adhesive 15 both can avoid position with adhesion glue frame 4 and iron-clad 1
Glue frame 4 in outside is turned up, and dustproof effect can also be played, and general double-sided adhesive is bonded in the straight line position of the two connection.In addition,
In order to enhance the dust reduction capability of backlight module, the corner location between the glue frame 4 and iron-clad 1 is bonded with dustproof adhesive tape 16, prevents
Dirt adhesive tape 16 can adopt one side glue, as long as the gap between glue frame 4 and iron-clad 1 can be blocked.
Refering to fig. 1 with 2, the iron-clad 1 is provided with the buckle 11 of inflection in installation 2 side of lamp bar, can be in 1 punching press of iron-clad
It is made together when molding, by the setting of buckle 11 in iron-clad 1 in installation 2 side of lamp bar, so that the heat dissipation of lamp bar 2 is more preferable.The film
Chip architecture 3 includes guide-lighting film 31, light-diffusing film 32, bright enhancement film 33 and reflectance coating 34, wherein the leaded light film 31 is caught in buckle
In 11, and pass through the inside that locating piece 12 is stuck in iron-clad 1, locating piece 12 is at least arranged both sides adjacent in iron-clad 1, can also set
It sets on three sides in addition to installing 2 side of lamp bar, it is thus achieved that the fixation of guide-lighting film 31, and be supported on side without setting and enter
Support construction in formula lamp bar.In addition, buckle 11 is also as the bonding platform for being bonded light-diffusing film 32 and bright enhancement film 33, the astigmatism
Film 32 and/or bright enhancement film 33 are bonded on buckle 11, as needed, only light-diffusing film 32 can be pasted on buckle 11, will be increased
Light film 33 is bonded on light-diffusing film 32, if there is multiple bright enhancement films 33 then stack gradually bonding；Bright enhancement film 33 can also be bonded
Pulled on 11 in button, light-diffusing film 32 be bonded on bright enhancement film 33 or guide-lighting film 31 on；It can also be by light-diffusing film 32 and bright enhancement film 33
It is successively bonded on buckle 11.Reflectance coating 34 is arranged below guide-lighting film 31, can be bonded in iron-clad 1.From there through one
A button, which pulls structure i.e., realizes the fixation of guide-lighting film 31, and the fixation of light-diffusing film 32 and bright enhancement film 33 may be implemented, relative to existing
Support leg is arranged on guide-lighting film and is supported in lamp bar some, and the structures such as step are arranged to fix light-diffusing film, bright enhancement film
Structure, modular structure is simpler, and assembling is more convenient, the reliability of installation it is also ensured that, or even installation is more reliable.
It is provided with anti-frictioning, the burr of 11 side of buckle is avoided to scratch with Fig. 2, the interior outside of the buckle 11 refering to fig. 1
The guide-lighting film 31 of downside and the light-diffusing film 32 of upside and bright enhancement film 33, the anti-frictioning are U-shaped, to encase 11 liang of buckle simultaneously
Side needs two sides to paste respectively when avoiding pasting anti-frictioning, time-consuming and laborious；And U-shaped glue also could be adhered to the end face of buckle 11,
Preferably protection diaphragm structure.The one side glue that anti-frictioning can use thickness relatively thick, encases buckle for the one side glue of bar shaped
It pastes in place 11 two sides.
It, can be with referring to Fig.2,11 two sides of buckle and 1 side plate of iron-clad are separated into two independent structures by gap 13
Gap 13 is first set before punch forming, by gap 13, that is, facilitates the punch forming of buckle 11, is also prevented from processing material extrusion shape
Become, that is, avoids influencing another when an appearance skew is abnormal in 1 side plate of buckle 11 and iron-clad.
Refering to fig. 1 and Fig. 2, it is provided with positioning tab 35 on the light-diffusing film 32 and bright enhancement film 33, the iron-clad 1 is provided with
Locating aperture 14, the positioning tab 35 are stuck in locating aperture 14, by locating aperture 14 and positioning tab 35, facilitate astigmatism
The positioning and fixation of film 32 and bright enhancement film 33 further promote the fixed reliability of diaphragm structure.
Refering to fig. 1, respectively with buckle 11 by T shape glue sticking, the glue surface of T shape glue is big for the light-diffusing film 32 and bright enhancement film 33
Side paste irony buckle 11 not easy to stick, the small side bonds of glue surface are easy the light-diffusing film 32 or bright enhancement film 33 of bonding.It is viscous
First be adhesively fixed light-diffusing film 32 when connecing, then the bright enhancement film 33 that is adhesively fixed.Multiple can be set in bright enhancement film 33, such as Fig. 1 settings
Upper and lower two bright enhancement films, and one above uses DBEF, Lai Jiaqiang light enhancing effect.
Refering to fig. 1 and Fig. 2 in order to further fix diaphragm is additionally provided with fixed station 17 on 1 side plate of iron-clad, described
Be provided on light-diffusing film 32 and bright enhancement film 33 with the matched attaching clamp 36 of fixed station 17, fixed station 17 and attaching clamp 36 are best
The other side of relative positioning opening 14 and positioning tab 35 is set, so that there is fixation at least three sides of diaphragm, is fixed more
Securely.Attaching clamp 36 on light-diffusing film 32 and bright enhancement film 33 preferably shifts to install, so that the diaphragm on upper layer may pass through lower layer
Diaphragm is contacted with fixed station 17, is bonded to facilitate with double-sided adhesive.Fixed station 17 be usually in 1 side plate upper opening of iron-clad,
It is more flat to be bonded when diaphragm is fixed, to guarantee the visual effect of mould group.Because being provided with light-diffusing film and bright enhancement film, fixed station 17
It is preferably provided as two-stage step, lower step is used to be bonded the light-diffusing film in lower layer, and higher step is used to be bonded closely
The bright enhancement film of light-diffusing film, it is more smooth so as to paste light-diffusing film and bright enhancement film.
Refering to fig. 1, soft rubber cushion 41 is provided in the glue frame 4 to facilitate subsequent installation liquid crystal display, guide-lighting film 31 removes lamp
Three sides outside side are equipped with bound edge 311, utilize again so that the light for projecting guide-lighting film is reflected back inside guide-lighting film.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in
Within the protection scope of the utility model claims.
