Embodiment
The utility model provides a kind of liquid crystal module and center and backboard assembly structure, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, below the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The center of a kind of liquid crystal module provided by the utility model and the preferred embodiment of backboard assembly structure, the center that it comprises a backboard and is fixed on described backboard surrounding, improvements of the present utility model are, be provided with convex closure at described backboard side, described center comprises a stair-stepping center body, described center body comprises first side and the Second Edge adjacent with first side, the height of the aspect ratio Second Edge of described first side is high, on described Second Edge, be provided with the fluting suitable with described convex closure, and be horizontally arranged with some outer muscle on the described first side position corresponding with fluting, and extend to the outside of Second Edge, be used for compressing backboard side, thereby prevent that center from turning up, the fluting of this center and outer muscle have formed a retaining structure, this retaining structure can block the convex closure on backboard side, thereby backboard is fixed.Below in conjunction with accompanying drawing, structure of the present utility model is specifically described.
As shown in Figure 2, backboard 100 sides at the utility model embodiment are provided with convex closure 110, it is bulge-structure, this convex closure 110 is for ensureing the screens of assembly structure and spacing, this convex closure 110 can directly be used mould (punch) impact briquetting, in general, the material that backboard adopts is generally high-strength aluminum alloy, its material is thick generally in 1.0mm left and right, this class material has good plasticity, so less demanding to punch in the time carrying out punching press, directly form convex closure 110 in backboard 100 side punching presses, after punching press, below this convex closure 110, leave corresponding hollow-out parts 120, the stressing conditions that the size of convex closure 110 can coordinate with center according to the size of whole module and backboard is determined, and need consider fit-up gap, can make convex closure can snap onto in center.
As shown in Figure 3, it comprises a stair-stepping center body 210 center 200 of the utility model embodiment, this center body 210 is made up of first side 211 and adjacent Second Edge 212, and first side 211 and Second Edge 212 are preferably one-body molded setting, the height of the aspect ratio Second Edge 212 of this first side 211 is high, thereby formed the staircase structure of length direction, be provided with the fluting 230 suitable with convex closure 110 on this Second Edge 212, this fluting 230 can block convex closure.Preferably, this fluting 230 extends laterally to the edge of Second Edge 212 from the inner side of Second Edge 212, be whole fluting 230 its there are three sides and support, another side (outside of Second Edge 212) arranges for open, form a drawer-type structure, so just conveniently the backboard 100 with convex closure 110 is inserted in center 200.In addition, on described first side 211 position corresponding with fluting 230, be horizontally arranged with some outer muscle 220, this outer muscle 220 is horizontally installed on center body 210 tops, there is enough gaps in outer muscle 220 parts and the Second Edge 212 of Second Edge 212 tops like this, be used for compressing backboard 100 sides.This structural change the structure of traditional inner side muscle, be about to be arranged on outside in the muscle of center inner side, directly match with backboard side, moulding process is obviously simplified, also rationally utilized fit-up gap simultaneously, center integral thickness reduces, for super narrow frame design provides more spaces.
As shown in Figure 4 and Figure 5, in the time of assembling, outer muscle 220 on center 200 is applied to acting force upwards, make the gap enlargement between outer muscle 220 and Second Edge 212, the one side then backboard 100 to convex closure 110 is inserted into fluting 230 positions of center 200, so just realize distortion screens, and whole retaining structure is compacter, as shown in Figure 6, in the middle of the convex closure 110 of backboard 100 sides is stuck in by the fluting 230 of inner side on center 200 and the outer muscle 220 in outside, from another one angle, as shown in Figure 7, outer muscle 220 on center 200 is pushed down backboard 100, from loading angle analysis, its reliability is obviously better than traditional Back Word type buckle structure, and outer muscle 220 is global formation settings, and there is no cut-out, so in the time of assembling, can bear larger moment of torsion, its assembling capacity obviously improves, and for convenience detach, reliability is also improved.
Further, be evenly distributed with multiple convex closures 110 in the surrounding of described backboard 100, to improve the stability of assembling.Corresponding, adaptive multiple flutings 230 and the corresponding multiple outer muscle 220 of being provided with on described center body 210.Illustrate, for the liquid crystal module of 55 cun, day, the each average mark in both sides be furnished with 8 convex closures, the each average mark of arranged on left and right sides is furnished with 7 convex closures, to realize the assembly reliability of center and backboard.
Preferably, described convex closure 110 be shaped as rectangular parallelepiped.For example, it is long is 7mm, and wide is 4.5mm, and height is 0.2mm, and radius of corner is 0.7mm.
Accordingly, in order to ensure to assemble rationality, the fluting 230 arranging on center 200, its size is general suitable with convex closure 110 sizes, and keeps an overgauge, be that space is relatively large, for example, for the convex closure of above-mentioned size, fluting 230 can be designed as: long is 7.4mm, and wide is 4.9mm, height is 0.3mm, and radius of corner is 0.8mm.And the distribution of fluting 230 is consistent with the distribution of convex closure 110, the outer muscle 220 arranging on center 200 is also consistent with the distribution of convex closure 110, and its size is slightly less than convex closure 110, generally remain on the minus deviation (monolateral) of 0.6mm to 0.9mm, to compress backboard 100.
Certainly, convex closure 110 should adjust accordingly according to the size of module with size and the quantity of fluting 230, above are only for example, and those skilled in the art can carry out accommodation to its size and quantity.
Based on said structure, the utility model also provides a kind of liquid crystal module, and it comprises center as above and backboard assembly structure.
In sum, the utility model by arranging convex closure structure on backboard side, and fluting is set on center, and anti-rolling muscle on center is arranged on to outside simultaneously and has formed outer muscle, in the time of assembling, convex closure is combined with the direct screens of fluting, and utilize outer muscle to compress backboard, thereby prevent that center from outwards tumbling, not only improved assembling capacity and reliability, also make the integral thickness of module reduce, machine-shaping is simpler, has reduced production cost.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
