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 Fig. 2, a kind of side-edge type backlight mould group of polymorphic structure, including lower frame 1, center 2, diaphragm unit 3
With lamp bar 4, lower frame 1 and center 2 are support and fixed structure, for supporting and fixing diaphragm unit 3 and lamp bar 4, so that backlight
Mould group has certain mechanical strength, and to guarantee that the normal mounting of mould group uses, the lamp bar 4 provides side light source, the fixation
Diaphragm unit 3 plays the role of astigmatism and changes the direction of propagation of light.The lower frame 1, center 2 and diaphragm unit 3 are shape one
The polymorphic structure of cause, such as be the mould group of the symmetrical structure of a similar wooden club shape, lower frame 1, center 2 and diaphragm in the present embodiment
Component 3 is the symmetrical structure of consistent similar wooden club shape.The diaphragm unit 3 is mounted in lower frame 1, through lower frame 1 in
Frame 2 fixes.The center 2 is mounted on lower frame 1, is generally clamped by buckle structure.The setting of lamp bar 4 exists
In lower frame 1 and light-emitting surface is towards the side of diaphragm unit 3, is generally bonded by bond plies.
Refering to fig. 1 and Fig. 2, the diaphragm unit 3 include successively folding scattering sheet 33, lower brightening piece 34 and the upper brightening piece set
35, lower 34 side of the brightening piece setting jagged 341, upper 35 side of brightening piece is provided with lug 351, the scattering sheet
It is be bonded by same sizing material between 33 and lower brightening piece 34 and upper brightening piece 35, for example, in Fig. 1 in scattering sheet 33, notch 341
Lower section be arranged double-sided adhesive 7, the length of double-sided adhesive 7 is longer than the length of notch 341, so that double-sided adhesive 7 is pasted onto scattering sheet on one side
On 33, another side part is Nian Jie with lower brightening piece 34, another part from notch 341 expose and it is Nian Jie with upper brightening piece 35, thus
It realizes and diaphragm is opened by the adhesion three simultaneously of same double-sided adhesive, bonding is more convenient, saves working hour, also saves Material Cost.It is logical
After crossing the bonding that the above method is completed between three diaphragms, three matrixs are connected into the boss on lower frame 1 by lug 351
Overall structure and lower frame 1 position adhesion, can be bonded by one side glue 9.It is thus achieved that between three matrixs and lower frame 1
It is fixed, it is easy to assembly in this way, expenditure of time is few, saves raw material.
Refering to fig. 1, in order to further enhance reliability be bonded between lower brightening piece 34 and upper brightening piece 35, the lower increasing
It is mutually bonded between mating plate 34 and upper brightening piece 35, lower brightening piece 34 is generally bonded in by double-sided adhesive 8 and is connect with upper brightening piece 35
The outside of contacting surface.For stronger Nian Jie with lower frame 1 of diaphragm unit, the lug 351 be arranged on upper brightening piece 35 with
The corresponding position of notch 341, thus bonding stress between diaphragm with the bonding stress of upper brightening piece in same position, bonding is more
Add securely.The quantity of bonded structure between above-mentioned diaphragm between bonded structure and diaphragm and lower frame can be set as needed
It sets, can be respectively provided in mould group surrounding when mould group is larger, one group can be arranged on one side when mould group is smaller.
Refering to fig. 1, the diaphragm unit 3 further includes reflecting piece 31 and light guide plate 32, and the reflecting piece 31 is fixed on lower frame 1
Interior, the light guide plate 32 is fixed in reflecting piece 31, and double-sided adhesive can be used and be adhesively fixed.The scattering sheet 33 is arranged in leaded light
On plate 32.
Refering to fig. 1, positioning column 321, the scattering sheet 33, lower brightening piece 34 and upper brightening piece are set on the light guide plate 32
Positioning port 36 is respectively provided on 35, the positioning port 36 is adapted with positioning column 321, i.e. scattering sheet 33, lower brightening piece 34 and upper increasing
It is positioned when mating plate 35 is placed on light guide plate 32 by positioning column 321 and the cooperation of positioning port 36, thus facilitate installation,
So that modular structure, which is used for a long time, has better stability.The light guide plate 32 is provided with support column close to the side of lamp bar 4
322, so that light guide plate 32 maintains a certain distance when installing with lamp bar 4, i.e., avoidable lamp bar 4 is collided damage, can also protect
Demonstrate,prove the vision light efficiency of backlight module.
Refering to fig. 1, lamp bar 4 described in the present embodiment be centre be vertical bar shape, two sides are forniciform structure, the lamp bar
The light direction of lamp on 4 everywhere is consistent, can be using LED light is arranged on FPCB using lamp bar 4, can shining LED light
Face is disposed as same direction, so that the uniformity that mould group two sides special-shaped part shines is more preferable, the uniformity of mould group Integral luminous
More preferably.The light-emitting surface of corresponding lamp is corresponding parallel everywhere with lamp bar 4 for light incident sides on the light guide plate 32, i.e., in light guide plate 32
The lateral location on both sides is set as the step parallel with lamp face in lamp bar 4, can guarantee the light incident sides on light guide plate 32
The light-emitting surface of corresponding lamp is corresponding parallel everywhere with lamp bar 4, and in this way, lamp bar 4 to light guide plate 32 enters light reflection less,
Light efficiency is high, so as to improve the brightness of mould group.
Refering to fig. 1, lamp bar 4 described in the present embodiment is side-emitting item, so as to which lamp bar to be attached in lower frame 1
On bottom surface, bigger position can be set to attach lamp bar 4, so that the two contact area is bigger, the heat dissipation of lamp bar 4 is easier.
Refering to fig. 1, the assembling of subsequent liquid crystal display for convenience, is provided with cushion rubber bumper 5 to place on the center 2
Liquid crystal display.It is provided with protective film 6 on the cushion rubber bumper 5, protects entire mould group by protective film 6 before placing liquid crystal display,
Avoid the dirty pollution diaphragm such as dust, when assembling liquid crystal display tears protective film 6.In order to facilitate dyestripping, protective film 6
On be additionally provided with dyestripping handle.
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.
