Specific implementation mode
The utility model is described in detail with reference to embodiment, embodiment is only the preferred reality of the utility model
Mode is applied, is not the restriction to the utility model.
It please refers to Fig.1 to Fig.3, the utility model provides a kind of display module comprising middle iron frame 1 and glue frame 2, it is described
Middle iron frame 1 is equipped with multiple fabrication holes, and the middle iron frame 1 includes orthogonal side wall 11 and bottom plate 12 two-by-two, the bottom plate
12 are equipped with fixed hole 121, and the diameter of 121 upper surface of the fixed hole is less than the diameter of lower surface；The glue frame 2 and institute
It states 1 integrated injection molding of middle iron frame and is set to 12 upper surface of the bottom plate.When glue frame 2 and middle 1 integrated injection molding of iron frame, liquid
The glue frame 2 of state can penetrate into inside fixed hole 121, to form the grasp of parallel direction, so that glue frame 2 exists with middle iron frame 1
It is fixed in parallel direction；Again since 121 upper surface of fixed hole is less than the diameter of its lower surface, glue frame 2 after molding and middle iron
Frame 1 forms the grasp on vertical direction, so that glue frame 2 is fixed in the vertical direction with middle iron frame 1.It can be to avoid glue frame
2 fall off the danger detached with middle iron frame 1, prevent light leak situation, improve product yield.
It should be noted that above-mentioned crystallized ability, but the quantity of fixed hole 121 can be realized in a fixed hole 121
More, crystallized ability is better, and the present embodiment is preferably 4, is evenly distributed near cornerwise endpoint of middle iron frame 1,
So that 2 uniform force of glue frame.And fixed hole 121 be set to bottom plate 12 it is intermediate when, rectangular, circular fixed hole can be used
121, design difficulty is low, good fixing effect, when fixed hole 121 is set to bottom plate 12 with 11 junction of side wall, then can adopt
With semicircular fixed hole 121, round and semicircle fixed hole 121 is not likely to produce burr, moreover it is possible to avoid increasing deburring
Technique.
Further, the cross-sectional shape of the fixed hole 121 is ladder-like, and stair-stepping fixed hole 121 can make
It forms the function as buckle, good fixing effect.
Fig. 4 and Fig. 5 are please referred to, further, the cross-sectional shape of the fixed hole 121 is ramped shaped, ramped shaped
Buckle function not only may be implemented in fixed hole 121, while can also be easy to disassemble, and replaceability is strong.
Usual glue frame 2 and the length of middle iron frame 1 are long, since middle iron frame 1 is different from the material of glue frame 2, irony
The 1 general coefficient of expansion of middle iron frame it is smaller, the coefficient of expansion can be neglected for glue frame 2, and the coefficient of expansion of glue frame 2
Generally between 0.5%-0.7%, the inconsistent coefficient of expansion will be with expanding with heat and contract with cold, and cause glue frame 2 that middle iron frame 1 is pullled change
Shape, 2 shape of glue frame is restored therewith after cooling, and the middle iron frame 1 for being pullled deformation can not then restore, and eventually lead to deformation of products.
Further, the glue frame 2 be equipped with stress relief grooves 21, when the size of glue frame 2 with expand with heat and contract with cold change when, stress
Release groove 21 can make the deflection of glue frame 2 in the location resolution of stress relief grooves 21, will not accumulate, also make the deformation of glue frame 2 not
The deformation of middle iron frame 1 can be pullled.
Preferably, the stress relief grooves 21 can be notch, can also be to allow glue frame 2 fragment position is thinning wherein,
Through-hole is either drawn in glue frame 2, principle is to make glue frame 2 in temperature change, and deflection is in setting stress relief grooves
21 location resolution, shall fall within the scope of the present invention.
More preferably, the utility model is typically used in glue frame 2 of the length more than 100mm, in some larger-size glue
In frame 2, the distance of adjacent each stress relief grooves 21 is 100mm, so that the stress in glue frame 2 is fully decomposed, is prevented
Only middle iron frame 1 deforms.
Further, wire drawing process is passed through in the upper surface of the bottom plate 12.It can also be coarse in 12 upper surface of bottom plate
Change is handled, and when glue frame 2 is with middle 1 integrated injection molding of iron frame, the glue frame 2 of liquid can penetrate into these wire-drawing surfaces can rough surface
On, to strengthen the grasp after integrated injection molding, glue frame 2 is further prevented to be detached with middle iron frame 1.
Referring to Fig. 6, further, the bottom plate 12 further includes bending part 122, the bending part 122 is embedded in the glue
Inside frame 2, using the structure, the outside of the therefrom folding edge of iron frame 1 of glue frame 2 is set to be wrapped up, the combination of glue frame 2 and iron frame
Area is big, and connection is compact, is not easily disconnected from.
Further, the glue frame 2 is equipped with step 22, which can be used for placing LCD modules 100, prevent LCD moulds
Group 100 is in direct contact with middle iron frame 1, and LCD modules 100 is avoided to burst apart.
Further, the step 22 is equipped with gasket 23.It is preferably foam, and foam can not only play LCD modules
Dustproof effect between 100 and glue frame 2, it can also be ensured that play cushioning effect in 100 assembling process of LCD modules.At other
Sandwich rubber can also be used in embodiment, can not only be functioned as described above, it can also be by backlight module 200 and LCD modules
100 stronger stickups are got up, and glue frame 2 is further prevented to be detached with LCD modules 100.
Referring to Fig. 7, it should be noted that when being not provided with step in glue frame 2, gasket 23 can also be set, it can
Gasket 23 is set on middle iron frame 1.Dust-proof shock-absorbing function can equally be played.
Above example only expresses the embodiment of the utility model, the description thereof is more specific and detailed, but can not
