Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
A kind of backlight module of liquid crystal indicator, described backlight module comprises: glue frame 100 and backboard 200.
Buckle 110 is stuck in the through hole 211.
Adopt this kind structure can avoid using screw stationary backplate and glue frame, the glue frame that has caused when having avoided playing screw is out of shape, thereby avoids the details in a play not acted out on stage, but told through dialogues light leak of liquid crystal indicator, has improved yield rate, has saved cost
An embodiment of the present utility model such as Fig. 2 are to shown in Figure 4.
Bridging 210 is the bridge-type structure towards the bending of glue frame 100 1 sides projection.
The buckle 110 of glue frame 100 has certain retractility, and buckle 110 is away from the size of the end 112 of the body of glue frame 100 size less than through hole 211.After this end 112 of buckle 110 enters through hole 211, press gradually buckle 110 downwards, because the size of buckle 110 becomes large gradually, when the size of buckle 110 during greater than the size of through hole 211, buckle 110 shrinks, after moving down certain distance again, the draw-in groove 111A of the lateral ridge 111 of buckle 110 is stuck in through hole 211 edges.Glue frame 100 is fixed on the backboard 200 at this moment.
Adopt this kind mode fixing glue frame 100 and backboard 200, can reduce the deflection of glue frame 100, and glue frame 100 is firmly cooperated with backboard 200, guaranteed the flatness in glue frame 100 fronts, make it when being assembled into complete machine, greatly alleviate the details in a play not acted out on stage, but told through dialogues light leak.
Preferably, two minor faces and a long limit towards the one side of backboard 200 of glue frame 100 have buckle 110., be furnished with buckle 110 on three limits, the back side of glue frame 100 herein, be used for backboard 200 fixing.Particularly, the both sides minor face respectively is furnished with the long limit of 3 buckle 110, one sides and is furnished with 4 buckles 110.
Further, also have buckle at the side of glue frame 100, cooperate with backboard 200, be used for strengthening fixation.
A kind of manufacture method of backlight module of liquid crystal indicator as shown in Figure 5, described backlight module comprises: glue frame and backboard.Described manufacture method comprises the steps.
Step S100 arranges buckle at the glue frame towards the one side of backboard.
Step S200 arranges the bridging of bending at backboard, the position corresponding with buckle arranges through hole putting up a bridge.
Step S300 is stuck in buckle in the through hole.
Adopt the method can avoid using screw stationary backplate and glue frame, the glue frame that has caused when having avoided playing screw is out of shape, thereby avoids the details in a play not acted out on stage, but told through dialogues light leak of liquid crystal indicator, has improved yield rate, has saved cost;
Preferably, described buckle is set to away from the size of the end of the body of the described glue frame size less than described through hole; The size of the end of the body of close described glue frame is greater than the size of described through hole.
Preferably, at described buckle lateral ridge is set; Near the end of the body of described glue frame draw-in groove is set at described lateral ridge; Described draw-in groove is stuck in the edge of described through hole.
Preferably, on one side with described lateral ridge from buckle away from the end of the body of described glue frame on one side the body direction to described glue frame stretch out.
The buckle of glue frame has certain retractility, and buckle is away from the size of the end of the body of the glue frame size less than through hole.After this end of buckle enters through hole, press gradually buckle downwards, because the size of buckle becomes greatly gradually, when the size of buckle during greater than the size of through hole, buckle contraction, after moving down certain distance again, the draw-in groove of the lateral ridge of buckle is stuck in the through hole edge.This moment, the glue frame was fixed on the backboard.
Adopt this kind mode fixing glue frame and backboard, can reduce the deflection of glue frame, and the glue frame is firmly cooperated with backboard, guaranteed the flatness in glue frame front, make it when being assembled into complete machine, greatly alleviate the details in a play not acted out on stage, but told through dialogues light leak.
Preferably, on two minor faces and a long limit towards the one side of backboard of glue frame buckle is set.
, be furnished with buckle on three limits, the back side of glue frame herein, be used for fixing with backboard.Particularly, the both sides minor face respectively is furnished with 3 buckles, and the long limit of a side is furnished with 4 buckles.
Further, also have buckle at the side of glue frame, cooperate with backboard, be used for strengthening fixation.
The above is preferred embodiment of the present utility model only, is not be used to limiting protection domain of the present utility model.All any modifications of within spirit of the present utility model and principle, doing, be equal to replacement, improvement etc., all be included in the protection domain of the present utility model.
