See also Fig. 1, a kind of framework of existing module backlight comprises a metal back frame 10 ' and a glue frame 20 '.Described metal back frame 10 ' has a base plate 11 ' and is vertically connected at the side plate 12 ' of base plate 11 ', wherein offers holes 13 ' respectively on two opposing sideplates 12 '.Described glue frame 20 ' utilizes the Inset ejection molding mode to be molded on the metal back frame 10 ' and makes the plastic cement of fusion inject holes 13 ' when moulding, thereby metal back frame 10 ' and glue frame 20 ' are formed as one, and make metal back frame 10 ' and glue frame 20 ' strong bonded.
Yet, the glue frame 20 ' of module backlight is when injection mo(u)lding, the flow direction of the plastic cement of fusion plastic cement when injecting holes 13 ' need produce unexpected transformation, thereby wants the pressurize long period that plastics are injected fully, therefore causes production efficiency low, of poor quality easily.
The utility model content
The purpose of this utility model is the defective that exists at prior art and not enoughly provides a kind of framework that the glue frame is molded over the module backlight of efficient on the metal back frame and quality that helps improving.
For achieving the above object, the framework of module backlight provided by the utility model comprises metal back frame and glue frame, metal back frame has a base plate, the periphery of described base plate upwards vertically is extended with a plurality of side plates, at least one side plate is formed with the clamping structure that extends to side plate one edge, the glue frame has the frame wall of the side plate inboard that is molded over metal back frame and is molded over holding division on the respective block wall, and this holding division and described clamping structure are entrenched togather.
As mentioned above, the framework of the utility model module backlight has replaced the holes in the background technology by the clamping structure that extends to side plate one edge that the side plate of metal back frame forms, when injection moulding glue frame, can be from the respective edges injection plastic cement of side plate, it is smooth and easy that thereby plastic cement flows, can shorten the dwell time of injection plastic cement, and then be beneficial to and improve the glue frame and be molded over efficient and quality on the metal back frame.

Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 2 and Fig. 3, it is first embodiment of the framework 1 of the utility model module backlight, comprises a metal back frame 10 and a glue frame 20.Metal back frame 10 has the base plate 11 of a rectangular plate shape, four peripheries of described base plate 11 upwards vertically are extended with side plate 12 respectively, described four side plates 12 are not connected each other, thereby between adjacent biside plate 12, keep at a certain distance away, wherein be respectively equipped with a clamping structure on two opposing sideplates 12, in the present embodiment, the groove 13 that extend laterally to side plate 12 both sides of the edge of this clamping structure for forming in the inboard of side plate 12 by the bending of the level and smooth arc in the middle part of side plate 12.See also Fig. 3 and Fig. 4,20 injection mo(u)ldings of glue frame on described metal back frame 10, its have be molded over the frame wall 21 that joining end to end of side plate 12 inboards connect and be molded on the respective block wall 21 with the corresponding holding division of clamping structure.This holding division be molded in the groove 13 and with the protuberance 22 of groove 13 tablings.The spatial accommodation that glue frame 20 and metal back frame 10 surround is in order to hold the optical element (not shown).Groove 13 is bent to form and extends laterally to side plate 12 both sides of the edge by the level and smooth arc in the middle part of described side plate 12, can make above side plate 12 and two side injection plastic cement, plastic cement all can flow more smooth and easy, thereby can shorten the dwell time of injecting plastic cement, and then be beneficial to efficient and quality that raising glue frame 20 is molded on the metal back frame 10.
See also Fig. 5, it is second embodiment of the framework 1 of the utility model module backlight.In the present embodiment, framework 1 structure of module backlight is basic identical among the framework 1 of module backlight and first embodiment, its difference is: in the present embodiment, the inwardly protruded lug boss 14 that extend laterally to side plate 12 both sides of the edge of described clamping structure for being formed in the inboard of side plate 12 by the level and smooth arc bending in the middle part of described side plate 12, described holding division are that the also recessed groove 23 of chimeric lug boss 14 is gone up on a moulding lug boss 14 surfaces.Lug boss 14 is bent to form and extends laterally to side plate 12 both sides of the edge by the level and smooth arc in the middle part of described side plate 12, can make above side plate 12 and two side injection plastic cement, plastic cement all can flow more smooth and easy, thereby can shorten the dwell time of injecting plastic cement, and then be beneficial to efficient and quality that raising glue frame 20 is molded on the metal back frame 10.
The clamping structure of the metal back frame 10 of the framework 1 of the utility model module backlight can also for bend repeatedly by side plate 12 convex-concave that forms in the inboard of side plate 12 alternate and extend laterally to side plate 12 both sides of the edge structure, 20 injection mo(u)ldings of glue frame and are molding on the frame wall 21 and the corresponding chimeric holding division of clamping structure on the side plate 12 on described metal back frame 10.
The bulge-structure or the sunk structure that only extend to side plate 12 1 edges that the utility model clamping structure also can form for impact briquetting.
In sum, the framework 1 of the utility model module backlight has replaced the holes 13 ' in the background technology by the clamping structure that extends to side plate 12 1 edges that the side plate 12 of metal back frame 10 forms, when injection moulding glue frame 20, can be from the respective edges injection plastic cement of side plate 12, it is smooth and easy that thereby plastic cement flows, therefore can shorten the dwell time of injection plastic cement, can improve glue frame 20 and be molded over efficient and quality on the metal back frame 10.
