One step detailed description.
Embodiment one
Refering to fig. 1 ~ 4, a kind of backlight module easy to assembly, including lower casing 1, lamp bar 2, reflector plate 3, light guide plate 4, upper ledge
5 and diaphragm unit 6, lower casing 1 and upper ledge 5 as the fixed other structures of structural member and support entire mould group, and lower casing 1 is generally metal
Material, upper ledge 5 can use plastic parts.Lamp bar 2 provides multiple point light sources by the multiple light sources being arranged thereon, reflector plate 3,
Point light source is converted to area source by light guide plate 4 and diaphragm unit 6.The lamp bar 2 is fixed at 1 inside of lower casing, and top can be used
The luminous side entering type lamp bar in face, and lamp bar is bonded in by bond plies the medial surface of lower casing 1, usually at mould group one
Lamp bar is arranged in side, can also be arranged as needed in multiple sides.
Refering to fig. 1 ~ 4, the reflector plate 3 and light guide plate 4, which are successively folded, is located in lower casing 1, and reflector plate 3 can pass through double-sided adhesive
It is bonded in the bottom in lower casing 1,4 four side of light guide plate is connected on 1 inner wall of lower casing.Light guide plate 4 can be set to one
Structure in the block of quadrangle, four sides are directly abutted with 1 inner wall of lower casing, can also be arranged on four sides and be abutted column and 1 inner wall of lower casing
It abuts.The upper ledge 5 is arranged above light guide plate 4 and fixes on lower casing 1, and the diaphragm unit 6 is fixed on upper ledge 5.It will
Light guide plate 4 is set as the form that can be abutted with 1 inner wall of lower casing, and light guide plate 4 is directly placed into lower casing 1 when installation, then will be upper
Light guide plate 4 can be fixed in lower casing by frame and lower casing clamping, be fixed without other fixed structures such as silica gel block, double-sided adhesive
Light guide plate, it is easy to assembly；Diaphragm unit 6 is fixed on above upper ledge 5, and upper ledge 5 has been fixed with lower casing, thus diaphragm unit 6
Fixed stability and better reliability are installed.
Refering to fig. 1 and Fig. 2, it is preferred that, 4 middle effective area of light guide plate described in the present embodiment is set as entire
Plate structure, surrounding, which is provided with, abuts column 41, and the light guide plate 4 is connected on 1 inner wall of lower casing by the abutting column 41 on four sides,
So as to reduce the materials'use of light guide plate 4, cost is saved, and mitigate light guide plate weight, it can mitigate mould group weight.
This light guide plate 4 can use one-time injection molding.
Refering to Fig. 3, in order to further fix light guide plate, 5 back side of upper ledge is provided with mutually fits with 4 surrounding structure of light guide plate
Downwardly projecting structure is arranged at 5 back side of upper ledge in the location structure 51 matched, which can avoid each abutting column 41, and
And be caught in the space that 4 periphery of light guide plate is formed with lower casing 1, upper ledge 5 can will further be led after fixing with lower casing from surrounding
Tabula rasa 4 is fixed, and the installation of light guide plate is just more stable.Location structure 51 can be arranged by the way of hollow out, that is, can reduce
5 weight of frame is also beneficial to 5 injection molding of upper ledge.
Refering to fig. 1, the specific embodiment fixed as a upper ledge 5 and lower casing, 1 inner wall of lower casing are provided with card slot
11,5 outer wall of upper ledge is provided with fixture block 53, is fixed between the lower casing 1 and upper ledge 5 by card slot 11 and fixture block 53, installation
When directly from top to bottom will upper ledge 5 be pressed into lower casing 1 in fixing can be completed, it is easy to assembly.Upper ledge 5 can also be adopted with lower casing fixing
With other it is common fix mode, such as upper ledge 5 is fixed on the outside of lower casing can also be with.
Refering to fig. 1, the diaphragm unit 6 includes successively folding the scattering sheet 61 set and brightening piece 62, in order to improve mould group
Brightness, brightening piece 62 can be set two layers.The scattering sheet 61 and brightening piece 62 are adhesively fixed on upper ledge 5, can be passed through
The outside of diaphragm is Nian Jie with upper ledge 5, and special bonded structure also can be set, such as: 62 side of the scattering sheet 61 and brightening piece
Face is provided with lug 63, and the upper ledge 5 is provided with groove 52 corresponding with lug 63, and the lug 63 is fixed on groove 52
It is interior, the lug of scattering sheet 61 and brightening piece 62 can be shifted to install, thus be adhesively fixed respectively scattering sheet 61 and brightening piece 62,
Lug can be set with position, each diaphragm can be fixed by an one side glue above.As shown in figure 1, the present embodiment uses one
The lug of kind more preferably mode, scattering sheet 61 and brightening piece 62 is arranged with position, but slightly misplaces, same so as to pass through
Multiple diaphragms are bonded by a realization of double-sided adhesive 64, and can be Nian Jie with upper ledge, i.e., the lug 63 of described scattering sheet 61 and brightening piece 62
Between be bonded by double-sided adhesive 64, and be bonded in groove 52 by double-sided adhesive 64.In order to enable diaphragm is bonded stronger, institute
Lug 63 is stated to be bonded on upper ledge 5 by one side glue 65.
It refering to fig. 1, can be in the side if lower casing 1 and the surface of upper ledge 5 do not connect and fix because structure needs
Face passes through encapsulated 7 bonding in side.For example, upper ledge 5 has portion sometimes for backlight module is improved to the bearing capacity of terminal glass mould group
Point side back side, which is directly pressed, to be attached on 1 wall of lower casing, and due to not connecting and fixing, upper ledge 5 loosens on lower casing 1 in order to prevent,
The side of itself and lower casing attaches side encapsulated 7 and the two is fixed together.Certainly the side fixed can also be further bonded
Side encapsulated 7 is reinforced.In order to protect mould group, protective film 8 is also set up, the protective film 8 is arranged above brightening piece 62, and glues
It connects on upper ledge 5, so as to dust-proof and diaphragm is avoided to be scratched.
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.
