Embodiment
The present invention provides a kind of module backlight; See also Fig. 3-Fig. 4 C; Shown in Figure 3 is decomposing schematic representation according to module backlight of the present invention; Fig. 4 A is depicted as the partial structurtes enlarged diagram according to first framework of the present invention, and Fig. 4 B is depicted as the partial structurtes enlarged diagram according to second framework of the present invention, and Fig. 4 C is depicted as the enlarged diagram according to the 3rd fixture of the present invention.Module 10 backlight comprises first framework 11, second framework 12 and at least one the 3rd fixture 13.First framework 11 has at least one first fixture 14; First fixture 14 is from the outwards turnover formation of the first side 16 of first framework 11; First fixture 14 comprises and linking to each other and L-shaped first plate body 41 and second plate body, 42, the second plate bodys 42 and the first side 16 formation first gap A.Wherein, first framework 11 for example is a backboard.And first fixture 14 and first framework 11 one-body molded.
The 3rd fixture 13 have body 31, first support arm 32 that extends in the same way from body 31 relative two ends and second support arm 33 and respectively from first support arm 32 and second support arm 33 extend in opposite directions first protruding 34 and second protruding 35; First protruding 34, first support arm 32 and body 31 form first groove, 36, the second protruding 35, second support arms 33 and body 31 forms second groove 37.Wherein the 3rd fixture 13 for example can adopt plastic cement material to process, but also not as limit.
See also Fig. 5 A, Fig. 5 B, Fig. 6 A and Fig. 6 B; Fig. 5 A and Fig. 5 B are depicted as the assembling synoptic diagram according to module backlight of the present invention; Fig. 6 A is depicted as along the diagrammatic cross-section of first embodiment of the module backlight of the AA ' line among Fig. 5 B, and Fig. 6 B is depicted as along the diagrammatic cross-section of the BB ' line among Fig. 5 B.Second framework 12 is positioned on first framework 11, and first side 16 connects with second side 17, and the 4th end face 56 is against first plate body 41.Then combine the 3rd fixture 13 and second fixture 15; Being about to first protruding 34 of the 3rd fixture 13 is arranged in first chute 57; And make second end face 54 at least partly be arranged in second groove 37, thereby the 3rd fixture 13 can be slided along first chute 57.When the 3rd fixture 13 when first 51 slides into second portion 52; First protruding 34 still is arranged in first chute 57; At this moment, second plate body 42 is arranged in second groove 37, corresponding; Second protruding 35 are arranged in the first gap A, and promptly first fixture 14 and second fixture 15 are fixing through the 3rd fixture 13.When needs are dismantled, also only need the 3rd fixture 13 be slid into first 51 from second portion 52, can make first fixture 14 and second fixture 15 break away from the fixing of the 3rd fixture 13, thereby first framework 11 and second framework 12 are disassembled.
And; Preferably; On the direction of edge first end face, 53 to second end faces 54; The closed at both ends of first chute 57 slides into second portion 52 or when second portion 52 slides into first 51, skids off the two ends of first chute 57 from first 51 along first chute 57 to prevent the 3rd fixture, certainly also not as limit.Wherein, In this embodiment; On a pair of relative first side 16 of first framework 11, be respectively arranged with one first keeper 14, be respectively arranged with one second keeper 15 in a pair of relative second side 17 of second framework 12, but in fact; The quantity and the relative position of first fixture 14, second fixture 15 and the 3rd fixture 13 do not limit, and only need to cooperatively interact to realize that the fixing of first framework 11 and second framework 12 gets final product.
And; In this embodiment, when second framework 12 is positioned over 11 last times of first framework, the first side 16 of the first 51 and first framework 11 forms the second gap M; When the 3rd fixture 13 is positioned at first 51; First protruding 34 is arranged in first chute 57, the second protruding 35 is arranged in the second gap M, thereby makes first protruding 34 and second protruding 35 of the 3rd fixture 13 slide along first chute 57 and the second gap M respectively; When the 3rd fixture 13 when first 51 slides to second portion 52, second protruding 35 is arranged in the first gap A.
See also Fig. 6 C, Fig. 6 C is depicted as along the diagrammatic cross-section of second embodiment of the module backlight of the AA ' line among Fig. 5 B.Module backlight in this embodiment and the module backlight in first embodiment; Difference is that second end face 54 ' of the second portion of second framework 12 has second chute 58; When the 3rd fixture 13 is positioned at first 51 '; First protruding 34 is arranged in first chute 57 ', the second protruding 35 is arranged in second chute 58.Thereby make first protruding 34 and second protruding 35 of the 3rd fixture 13 slide along first chute 57 ' and second chute 58 respectively, when the 3rd fixture 13 when first 51 ' slides to second portion 52, second protruding 35 is arranged in the first gap A.Thereby through the 3rd fixture 13 fixing first fixture 14 and second fixtures 15.Likewise, also only need the 3rd fixture 13 be slid into first 51 ' from second portion 52, can make first fixture 14 and second fixture 15 break away from the fixing of the 3rd fixture 13, thereby first framework 11 and second framework 12 are disassembled.
In addition, the present invention also provides a kind of display device 70, sees also Fig. 7, and shown in Figure 7 is synoptic diagram according to display device of the present invention.Display device 70 comprises display panel and aforesaid module backlight 10, and module 10 backlight provides light source for display panel.Display device 70 also comprises the 3rd framework 72, the three frameworks 72 assembling module 10 backlight and display panels, and wherein the 3rd framework 72 for example is last chase or preceding frame.
The 3rd framework 72 has at least one opening 73, and opening 73 is positioned at the 3rd side 74 of the 3rd framework 72, and wherein the second side 17 of the first side 16 of the 3rd side 74 and first framework 11 and second framework 12 is corresponding; And when the 3rd fixture 13 when first 51 slides into second portion 52 and be positioned at apart from farthest position of first 51, opening 73 combines fixing with the 3rd fixture 13, promptly the 3rd fixture 13 is fastened in the opening 73.That is; Before 72 assemblings of the 3rd framework; The end that must the 3rd fixture 13 be pushed into first chute 57 fully locatees first framework 11 and second framework 12 promptly like the low order end among Fig. 5 B, otherwise; Can not produce interference owing to the 3rd fixture 13 can't engage with opening 73 relatively, make the 3rd framework 72 to assemble.After the 3rd framework 72 snapped in, the 3rd fixture 13 engages with opening 73 made that the 3rd fixture 13 is fixed firmly, thus fixing further first framework 11 and second framework 12.When disassembling, then need earlier the 3rd framework 72 to be pulled down, make the 3rd fixture 13 and opening 73 break away from, carry out disassembling of the 3rd fixture 13 again.
In sum; Its glue frame of display device of the present invention and module backlight thereof and backboard adopt the location fit structure of slidingtype, and not only locating effect is firm, and installing/dismounting is all very convenient; And can not block plastic emitting frame bits, thereby guarantee the assembling quality and the packaging efficiency of this module backlight.
By the detailed description of above preferred embodiment, be to hope to know more to describe characteristic of the present invention and spirit, and be not to come protection scope of the present invention is limited with the above-mentioned preferred embodiment that is disclosed.Therefore, the protection domain of the claim that the present invention applied for should be done the broadest explanation according to above-mentioned explanation, contains the arrangement of all possible change and tool equality to cause it.
