Embodiment

Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Please in the lump referring to Fig. 1 to Fig. 6, Fig. 1 is the partial exploded view of liquid crystal panel preferred embodiment of the present utility model; Fig. 2 is the partial sectional view of the liquid crystal panel among Fig. 1; Fig. 3 is fore shell among Fig. 1 and the partial exploded view of heat radiator; Fig. 4 is fore shell among Fig. 1 and the subssembly drawing of heat radiator; Fig. 5 is the A portion enlarged drawing of the heat radiator among Fig. 3; Fig. 6 is the side view of heat radiator among Fig. 3.Extremely shown in Figure 6 as Fig. 1, described LCD comprises fore shell 100, is positioned at the liquid crystal panel 200 of fore shell 100 1 sides and the glue frame 400 of support liquid crystal panel 200, liquid crystal panel 200 ends have COF(and cover brilliant film) 210, have some Source IC(source driving chips on the COF 210) 211, this Source IC 211 generates heat when working and causes whole C OF210 heating.If the COF210 temperature above the plastic cement fusing point, just may cause fore shell 100 to burn and cause bad order.Therefore also between fore shell 100 and COF210, be provided with the heat radiator 300 of the some metal materials with excellent heat conductivity performance, in time the heat on the COF210 is dissipated, heat radiator 300 can be fixed in fore shell 100 by screw or buckle structure, present embodiment preference card buckle structure.This buckle structure as shown in Figure 3 and Figure 4, comprise two Elastic buckles 310 that are convexly set in heat radiator 300 two ends, and be convexly set on the fore shell 100 with a plurality of heat radiator 300 on Elastic buckle 310 a plurality of spacing gussets 110 one to one, if heat radiator 300 is long, Elastic buckle 310 also can arrange a plurality of, to increase fastness.Elastic buckle 310 comprises first holding section 311 and second holding section 312, first holding section 311 is convexly set in heat radiator 300 toward extending away from these heat radiator 300 directions, preferably perpendicular with heat radiator 300 bottom surfaces, it is terminal toward the extension of heat radiator 300 directions that second holding section 312 is connected in first holding section 311, has a space between first holding section 311 and second holding section 312, spacing gusset 110 just is sticked between first holding section 311 and second holding section 312 after clamp-oning this space by force, thereby heat radiator 300 just is fastened on the fore shell 100.Heat radiator 300 and Elastic buckle 310 thereof can the integrated punching moulding, the processing simple and fast.

Further, second holding section 312 is terminal toward bending away from first holding section, 311 directions, to enlarge the opening in the space between first holding section 311 and second holding section 312, to be formed with the introducing port that is beneficial to spacing gusset 110 insertion spaces, more convenient during assembling.

Further, as shown in Figure 5 and Figure 6, have a through hole 3111 on first holding section 311, these through hole 3111 sidewalls protrude out an elasticity muscle sheet 3112 obliquely toward second holding section, 312 directions, this elasticity muscle sheet 3112 can form by going out through hole 3111 back bendings, and processing is simple.Extruding elasticity muscle sheet 3112 behind the space that spacing gusset 110 inserts between first holding section 311 and second holding section 312, make elasticity muscle sheet 3112 toward the 311 direction generation elastic deformations of first holding section, elasticity muscle sheet 3112 reacts on spacing gusset 110, and spacing gusset 110 is sticked in the space securely.

Further, second holding section 312 has one toward the outstanding teat 3121 of first holding section, 311 directions, as shown in Figure 6, second holding section 312 is S-shaped substantially, the distance of two ends and first holding section 311 is far away and greater than the thickness of spacing gusset 110 up and down, the close together of middle teat 3121 and first holding section 311 and less than the thickness of spacing gusset 110, and the elasticity muscle sheet 3112 on this teat 3121 and first holding section 311 is oppositely arranged, under the common squeezing action of this teat 3121 and elasticity muscle sheet 3112, spacing gusset 110 is stuck more firmly.During assembling, produce friction between 110 need of spacing gusset and teat 3121 and the elasticity muscle sheet 3112, friction area is less, laborsaving saving time.

Further, at the back side of heat radiator 300 also namely this heat radiator 300 and fore shell 100 one side of fitting attach double faced adhesive tape, and fore shell 100 correspondences arrange a convex closure 120, heat radiator 300 is attached at by double faced adhesive tape on the convex closure 120 of fore shell 100, with heat radiator 300 more firm be fixed in fore shell 100.

During assembling, attach double faced adhesive tape earlier at heat radiator 300 back sides, then the Elastic buckle 310 of heat radiator 300 is aimed at corresponding spacing gusset 110 on the fore shell 100, because first holding section 311 of Elastic buckle 310 and the space between second holding section 312 have introducing port, can easily spacing gusset 110 be imported, press heat radiator 300 toward fore shell 100 directions immediately, spacing gusset 110 is clamp-oned the gap between the elasticity muscle sheet 3112 of the teat 3121 of second holding section 312 and first holding section 311 under pressure by force, force teat 3121 past away from the 311 direction deformation of first holding section, elasticity muscle sheet 3112 is past away from the 312 direction deformation of second holding section, in the space that enters fully by this gap between first holding section 311 and second holding section 312, spacing gusset 110 just is highlighted

portion

3121 and 3112 firm being fixed of elasticity muscle sheet, and heat radiator 300 also is adhered fixed on the convex closure 120 of fore shell 100 by double faced adhesive tape simultaneously.

Assembled after all heat radiator 300, just liquid crystal panel 200 has been assemblied in fore shell 100 1 sides, glue frame 400 has been installed again, supported this liquid crystal panel 200.COF210 on the liquid crystal panel 200 is corresponding with heat radiator 300, and the Source IC211 on the COF210 closely contacts with heat radiator 300, heat on the Source IC211 just is directly passed to heat radiator 300, in time heat is distributed by heat radiator 300, avoid accumulation of heat to cause the too high fore shell 100 of burning of temperature in COF210, influence outward appearance.

To sum up, the LCD of present embodiment by between COF210 and fore shell 100 heat radiator 300 being set, in time the heat on the COF210 is dissipated, prevents accumulation of heat on the COF210 and the fore shell 100 of burning, and causes bad order.And heat radiator 300 conveniently is assemblied on the fore shell 100 by simple and reliable buckle structure, and production cost is lower.

Should be understood that; it below only is preferred embodiment of the present utility model; can not therefore limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
