Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
It please refers to Fig.1 and Fig. 2, the present invention provides a kind of backlight module, including：Glue frame 1 and iron frame 2, the glue frame 1 are embedded in
2 inside of the iron frame coordinates mounting structures of the frame as backlight module using the glue frame 1 and the iron frame 2, can improve mould
The reliability and intensity of group, moreover it is possible to preferably meet the requirement to narrow frame.
Fig. 3 to Fig. 5 is please referred to, the glue frame 1 includes：Glue frame bottom plate 11 is respectively arranged on 11 four side of glue frame bottom plate
On several steps 12, be respectively arranged on 11 four side of glue frame bottom plate it is several first opening 13.The step 12 and institute
The setting of the first opening 13 interval is stated, step 12 described in this segmentation structure is a section short distance step, in injection molding
When be easier, avoid long range narrow side step injection molding when difficult forming the problem of.The step 12 is rectangle, the step
12 short side is vertical with 11 side of glue frame bottom plate, the part of the step 12 be located at 11 surface of glue frame bottom plate its
Remaining part point is located at 11 outer side surface of glue frame bottom plate, and the step 12 can play the role of fixed liquid crystal display, while can be with
Play the role of protection.
Fig. 6 to Fig. 8 is please referred to, the iron frame 2 includes：Iron frame bottom plate 21 is respectively arranged on 21 four side of iron frame bottom plate
On several second openings 22, several bending gears 23 for being respectively arranged on 21 four side of iron frame bottom plate.The bending shelves
Position 23 is arranged with described second 22 intervals that are open, and the bending gear 23 is upwardly extended and is bent to form for the iron frame bottom plate 21,
The bending gear 23 can play the role of fixed protection liquid crystal display.The bending gear 23 is with the iron frame bottom plate 21 at one
Determine angle, the certain angle is 87 ° -90 °.The bending gear 23 is inwardly slightly tilted certain angle, can be by backlight glue frame
That blocks is more secured, is not easily disconnected from, and specifically, the bending gear 23 is 89 ° with 21 angulation of iron frame bottom plate, this timeliness
Fruit is more excellent, can play the role of fixed with glue frame.
Further, the glue frame 1 further includes the raised line 14 being set in each first opening 13, correspondingly, institute
It further includes on each bending gear 23 and a through-hole 24 corresponding with the raised line 14 to state iron frame 2, the raised line
14 are embedded in the through-hole 24, are sticked in the through-hole 24 by raised line 14 and glue frame 1 is fixed on iron frame 2, make institute
State that glue frame 1 and the iron frame 2 combine more securely.Preferably, the raised line 14 is set to described first and is open on 13 end face.
Alternative, 23 top of bending gear is recessed a recess portion 25, recess portion 25 described in the present embodiment
Above the through-hole 24.The recess portion 25 concaves towards 23 inside of the bending gear, referring to Fig. 2, the recess portion 25 coordinates institute
Raised line 14 is stated, the raised line 14 is made to be not easy, keeps the combination of the glue frame 1 and the iron frame 2 more firm.
