Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
It should be noted that, when element is called as " being fixed on " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.Term as used herein " vertical ", " level ", "left", "right" and similar statement just for illustrative purposes, do not represent it is unique embodiment.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in description of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Referring to Fig. 1, is the decomposing schematic representation of the backlight module 10 in an embodiment.This backlight module 10 comprises frame structure 100, the light guide plate 200 be cascading, diffusion sheet 300, lower brightening piece 400, upper brightening piece 500, anti-dazzling screen 600 and reflecting piece 700.Reflecting piece 700 is attached at the bottom surface of frame structure 100, for reflection ray.
Seeing also Fig. 2 and Fig. 3, is the schematic diagram of the frame structure 100 in an embodiment.Frame structure 100 comprises metal frame 110 and glue frame 120.Frame structure 100 is mainly used in carrying light guide plate 200, diffusion sheet 300, lower brightening piece 400, upper brightening piece 500 and anti-dazzling screen 600.Particularly, can by offering embedded groove (not shown) on the madial wall of glue frame 120, the edge of light guide plate 200, diffusion sheet 300, lower brightening piece 400, upper brightening piece 500 and anti-dazzling screen 600 embeds in this embedded groove (not shown), to be carried on frame structure 100 respectively.
The roughly rectangular structure of metal frame 110, metal frame 110 can be chase.Certainly, metal frame 110 can also be made for the metal that other intensity is higher.Metal frame 110 has and the first edge 111, edge 111, first offers the first accepting groove 1111, first accepting groove 1111 and be mainly backlight and reserve installation position.Particularly, the projection of backlight on metal frame 110 is positioned at the first accepting groove 1111.Other edge of metal frame 110 all offers through hole 112.Through hole 112 can be circular port particularly, and the quantity of circular port is multiple, and circular port is distributed in the edge of metal frame 110 equably.The diameter of circular port can be 0.4mm.Through hole 112 is circular port, can reduce the shock surface of chase, and the surface area of chase is increased, and when glue frame 120 injecting glue impacts, chase is not easy distortion.Meanwhile, because the surface area of chase increases, the contraction ratio of glue frame 120 reduces, thus reduces the plane warping degree of glue frame 120 to a certain extent.
The roughly rectangular structure of glue frame 120, glue frame 120 passes through injection mo(u)lding.Glue frame 120 has and the second edge 121, edge 121, second offers the second accepting groove (figure does not mark), and the second accepting groove (figure does not mark) is corresponding with the first accepting groove 1111.Second accepting groove is mainly backlight and reserves installation position, and particularly, the projection of backlight on glue frame 120 is positioned at the second accepting groove.Distance D1 between the bottom of the second accepting groove of glue frame 120 and the madial wall of glue frame 120 is not more than 0.4mm.
Specific in present embodiment, first chase is adopted punching process forming, then the chase of forming is utilized mould secondary injection mo(u)lding on injection machine.Because chase offers through hole 112, so when injection mo(u)lding glue frame 120, injecting glue can flow in through hole 112, thus form to the one side of metal frame 110 the protruding (not shown) embedded in through hole at other edge surface of glue frame 120, thus ensure that other edge of glue frame 120 and other edges close of metal frame 110 are fitted.
The bottom of the first accepting groove 1111 of metal frame 110 offers at least one group of groove 113, and often group has two spaced grooves 113, and metal frame 110 part between two grooves 113 bends towards glue frame 120 direction and embeds in glue frame 120.Particularly, angle metal frame 110 part between two grooves 113 bent towards glue frame 120 direction can be an acute angle or right angle.The degree of depth of groove 113 is less than the thickness of glue frame 120, the degree of depth of groove 113 determines that metal frame 110 embeds the degree of depth in glue frame 120, so the degree of depth of groove 113 is arranged to the thickness being less than glue frame 120, the part avoiding metal frame 110 to embed groove 113 runs through the thickness of glue frame 120.
Specific in present embodiment, the bottom of the first accepting groove 1111 of metal frame 110 offers 2 ~ 6 groups of grooves 113, often organizes interval between two grooves 113 in groove 113 and arranges.Spacing between two adjacent groups groove 113 is greater than the spacing between interior two grooves 113 of group, needs the length of bending metal frame 110 part little, more easily bends.Many group grooves 113 are set, are conducive to increasing metal frame 110 and embed surface area in glue frame 120, make the tightr of glue frame 120 and corrupt split.
Certainly, refer to Fig. 4 and Fig. 5, for the schematic diagram of frame structure 100 in other embodiment, in this embodiment, one group of groove 113 is only offered in the bottom of the first accepting groove 1111 of metal frame 110, and two grooves 113 in group lay respectively at the edge bottom the first accepting groove 1111, thus makes the length of the part that metal frame 110 is bending larger, to increase the surface area that metal frame 110 embeds glue frame 120, make the tightr of glue frame 120 and corrupt split.
Above-mentioned backlight module 10 and frame structure 100 thereof at least have the following advantages:
The first accepting groove 1111 is offered at first edge 111 of metal frame 110, second accepting groove corresponding with the first accepting groove 1111 is offered at the second edge 121 of glue frame 120, thus reserves installation position to backlight; At other edge through hole 112 of metal frame 110, form the protruding (not shown) that can embed in through hole 112 at other edge of glue frame 120, other edge of metal frame 110 and other edge of glue frame 120 can be made to fit more closely more stable; Offer at least 1 group groove 113 in the bottom of the first accepting groove 1111 of metal frame 110 simultaneously, often group has two spaced grooves 113, metal frame 110 part between two grooves 113 bends towards glue frame 120 direction and embeds in glue frame 120, when the inwall distance of the bottom of the first accepting groove 1111 and glue frame 120 is less, also metal frame 110 and glue frame 120 can be made to fit tightly, thus reduce the plane warping degree of glue frame 120.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
