Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of backlight module, and referring to figs. 1 through Fig. 3, in one embodiment, this backlight module comprises backboard 4, be fixed on the installing frame 1 on described backboard 4 sidewall and be positioned at the blooming piece 2 above and inside installing frame 1 of described backboard 4.Described blooming piece 2 comprises lamellar body 21 (be rectangle in the present embodiment, and all do not illustrate) and is located at the hangers 22 of described lamellar body 21 periphery, and described hangers 22 is provided with through hole 221.Described backlight module also comprises and to connect with described installing frame 1 and the Elastic buckle 3 that arranges of corresponding described hangers 22, and in the through hole 221 that described Elastic buckle 3 is set in described hangers 22, and elasticity is conflicted, the edge of described through hole 221 moves in the plane at described lamellar body 21 place to limit described blooming piece 2.
Above-mentioned backlight module, the through hole 211 passing hangers 22 by the Elastic buckle 3 be fixed on installing frame 1 limits the movement of blooming piece 2 in the plane at lamellar body 21 place.On the one hand, manually blooming piece accurately installed relative to the needs in existing backlight module and be positioned to above backboard 4, to be limited the movement of blooming piece 2 in the plane at lamellar body 21 place by backboard 4; Blooming piece 2 can be automatically mounted on described backboard 4 by automation equipment in this case, and then installing frame 1 is mounted on backboard 4, and Elastic buckle 3 is set in the through hole 221 of described blooming piece 2, be accurately positioned on backboard 4 to make blooming piece 2.Therefore the assembly work that the backlight module in this case needs is shorter, and efficiency is higher.On the other hand, the backboard 4 of the backlight module in this case does not need to arrange the structure for accurate positioning optical diaphragm 2, and therefore the structure of backboard 4 can be simpler, and difficulty of processing is lower and volume production stability is higher.Again on the one hand, at blooming piece 2 by cold events, expanded by heating or when shaking, the deformation of blooming piece 2 or displacement will conduct on Elastic buckle 3, and the edge of the through hole 221 of blooming piece 2 is flexibly contacted at due to Elastic buckle 3, thus Elastic buckle 3 can elastic deformation with the deformation of adaptive optics diaphragm 2 or displacement, thus can avoid blooming piece 2 occur scratch or fold bad.
Particularly, described Elastic buckle 3 comprises separating part 31 and elastic portion.Described separating part 31 is convexly equipped in the inner surface 11 of described installing frame 1 and is positioned at the light emission side of described blooming piece 2; Described elastic portion is convexly equipped in the side towards described blooming piece 2 of described separating part 31, and wears elasticity to described through hole 221 and to conflict the edge of described through hole 221.Thus reach the effect of restriction blooming piece 2 movement in the plane at described lamellar body 21 place.
In the present embodiment, elastic portion comprises the location division 32 connecting described separating part 31 and the shrapnel part 33 angularly arranged with described location division 32, the elastic portion V-shaped (as shown in Figure 3) that described location division 32 forms with shrapnel part 33, and one end V-shaped in described elastic portion is set in the through hole 221 of described blooming piece 2.When assembling, because V-shaped elastic portion be tip towards one end of described blooming piece 2, this tip is significantly less than the through hole 221 of blooming piece 2.So when assembling, V-shaped elastic portion will be convenient to insert in described through hole 221, thus reach and be convenient to be mounted to the effect on blooming piece 2.
In the present embodiment, described shrapnel part 33 is connected with described location division 32 and inner surface towards described installing frame 1 extends, thus makes described shrapnel part 33 V-shaped with described location division 32.The one side of described shrapnel part 33 described location division 32 dorsad contacts at the edge of described through hole 221.Particularly, blooming piece 2, will towards its central reduction when catching a cold; When being heated, will expand to its surrounding.Incorporated by reference to referring to Fig. 4, described blooming piece 2 is making described shrapnel part 33 produce towards the elastic deformation of described location division 32 by extruding described shrapnel part 33 during cold events, and namely shrapnel part 33 can become the state as shown in 33b.Described blooming piece 2 described shrapnel part 33 when expanded by heating is recovered elastic force and is evened up to surrounding by described blooming piece 2, and namely shrapnel part 33 becomes state 33a from state 33b.Wherein, the 33a of Fig. 4 is the state of shrapnel part 33 when not being subject to the pulling force of blooming piece 2, state when namely shrapnel part 33 is not set in the through hole 221 of blooming piece 2.Namely after mounting, shrapnel part 33 is applied with the elastic force of being evened up to surrounding by described blooming piece 2 all the time to described blooming piece 2.
Please again referring to Fig. 2 and Fig. 4, in the present embodiment, on described location division 32, the position of corresponding described shrapnel part 33 offers resigning hole 34, for at low temperatures, described shrapnel part 33 produces the position of elastic deformation to state 33b when being subject to the pulling force inwardly shunk from blooming piece 2, and is contained in described resigning hole 34.
Certainly, except the elastic portion of this programme is V-shaped, in other embodiments, elastic portion also can be other shapes.Such as elastic portion is W shape or arrow shaped, the location division 32 comprising two shrapnel part 33 and be connected between two shrapnel part 33, and location division 32 is connected with separating part 31; Or one shrapnel part 33 between another shrapnel part 33 and location division 32.Certain elastic portion also only can comprise the shrapnel part 33 be connected with described separating part 31, and whole elastic portion is L-shaped.In other embodiments, the separating part of described Elastic buckle 3 also can be located at the incident side of described blooming piece 2, and elastic portion extends to the light emission side of described blooming piece 2.
Particularly, the quantity of described hangers 22 is multiple (not shown), is located at the periphery of described blooming piece 2 evenly and at intervals.Correspondingly, described Elastic buckle 3 is also multiple, and the setting of corresponding described hangers 22.
Further, described installing frame 1 comprises the first glue frame and the second glue frame, and described first glue frame surrounds the periphery of described blooming piece 2 and fixes with described backboard 4; Described second glue frame is connected with described first glue frame and extends inside installing frame along the direction being parallel to described blooming piece; Described Elastic buckle 3 is connected with described second glue frame.In the present embodiment, the first glue frame is connected with the second glue frame one, and Elastic buckle 3 is also integrated with the second glue frame and is connected.In other embodiments, also can be that Elastic buckle 3 is integrated with the second glue frame and is connected, described second glue frame is bonding with the first glue frame, weld, clamping or be spirally connected.One set of die is passed through integrally manufactured by Elastic buckle 3 and the second glue frame, then by Elastic buckle 3 and the second glue frame integral installation to the first glue frame.
The utility model also provides a kind of display, and this display comprises above-mentioned backlight module disclosed in the utility model, and the structure of this backlight module can refer to above-described embodiment, does not repeat them here.Naturally, the display due to the present embodiment have employed the technical scheme of above-mentioned backlight module, and therefore this display has all beneficial effects of above-mentioned backlight module.
