Abstract
The utility model discloses a kind of iron frame structure of backlight module, comprise chase, the side of this chase is coated by glue frame, the side of chase is provided with the rectangle via hole of band chamfering, the corner location of chase arranges circular vias, the side of chase is provided with bending screens, and this bending screens has an exterior angle towards chase outside and an interior angle towards chase inside, and this exterior angle and interior angle are all set to rounding.The utility model Stability Analysis of Structures is reliable, and glue frame and chase are not easily separated, effectively improve the flatness of product.
Description
Technical field
The present invention relates to a kind of backlight module, specifically a kind of iron frame structure of backlight module.
Background technology
LED-backlit module is the important spare part of liquid crystal display, and its structure affects the aesthetic appearance of liquid crystal display terminal product dramatically.Pursue today of super large, ultrathin at products application, LED-backlit module also thins down, in order to better be adapted to the requirement of ultra-thin liquid crystal glass, then the flatness requirement of backlight module is also more and more higher.
Backlight module generally all comprises the parts such as chase, glue frame, light guide plate and reflectance coating, wherein chase needs to carry out die-cut in the process manufactured, chase can produce stress when carrying out die-cut operation and being shaping, if this stress controls bad, the flatness of chase then can be made to can not get ensureing, and the flatness of chase can not be guaranteed, whole backlight module can be caused to there is the problem of flatness.And, chase and glue frame to be integrated and to form glue chase by part, and glue chase exists segregative problem in shaping process, if glue chase is separated and comes off (be generally glue frame come off separation) when shaping, then cause the increase of production cost, also reduce production efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of effective flatness improving product, improves the iron frame structure of the backlight module of the reliability of structure.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
An iron frame structure for backlight module, comprises chase, and the side of described chase is coated by glue frame, and the side of described chase is provided with bending screens, and this bending screens has an exterior angle towards chase outside and an interior angle towards chase inside.
Exterior angle and the interior angle of described bending screens are all set to rounding.
Described bending screens is located at the corner areas of chase.
Described glue frame is installed in the bending screens of chase.
The side of chase is provided with side via hole, and the corner location of chase arranges corner via hole.
Described side via hole is the rectangle via hole of band chamfering, and corner via hole is circular vias.
Described glue frame is formed in the injection mo(u)lding of chase side by sizing material, in chase side is wrapped in by this glue frame.
The utility model is by arranging the bending screens of two rounding structure by chase, ensure the Stability Analysis of Structures reliability of chase and glue frame, not easily separated in the production run making glue frame be molded on chase, and use glue frame parcel at the side of chase, add the tension force of strong rubber chase, also by the setting of via hole, the stress that chase produces when punching molding can be eliminated, solve the flatness problem of chase, thus effectively improve the flatness of product.
Accompanying drawing explanation
Accompanying drawing 1 is perspective view of the present invention;
Accompanying drawing 2 is A place structure for amplifying schematic diagram in accompanying drawing 1.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention is further described.
As shown in figure 1 and 2, present invention is disclosed a kind of iron frame structure of backlight module, comprise chase 1, the side of chase 1 is coated by glue frame 3, the side of described chase 1 is provided with bending screens 4, and this bending screens 4 has an exterior angle 41 towards chase 1 outside and an interior angle 42 towards chase 1 inside.This bending screens 4 is preferably arranged on the corner areas of chase.In chase 1 is enclosed in by glue frame 3, chase and glue frame become glue chase integrative-structure.Chase has four sides usually, also has four corner locations, and these four corner locations are all provided with bending screens, and this bending screens is curved inwardly by chase side and formed.Exterior angle 41 and the interior angle 42 of bending screens 4 are all set to rounding, thus make the screens of this change folding have two rounding.Glue frame is also arranged and bends screens accordingly, by the bending screens of this pair of rounding structure of chase can be reliable and stable fasten with glue frame and install, ensure glue frame and chase not easily separated in process of production.Glue frame is formed in the injection mo(u)lding of chase side by sizing material, in chase side is wrapped in by this glue frame, is wrapped up thus shaping glue frame by chase by mould-injection, forms glue chase integrative-structure.
In addition, the side of chase 1 is provided with side via hole 2, and the corner location of chase 1 arranges corner via hole 5.Side via hole is the rectangle via hole of band chamfering, and corner via hole is circular vias.This rectangle via hole can arrange multiple, and for corner via hole, a general edge just only arranges a corner via hole.
The present invention is by arranging the bending retaining structure of the two rounding of band, not easily separated in the process that glue frame can be prevented shaping on chase, improves the reliability of iron frame structure.And by wrapping glue frame at chase side, the tension force of strong rubber chase can be added, strutting chase during use plastic rubber shaping and strengthening its rigidity, to solve the flatness problem of glue iron integration backlight module when shaping, effectively improve the flatness of product.And by arranging rectangle via hole and circular vias on chase, make chase also can be eliminated by the adjustment of crossing hole site when punching molding its shaping time the stress that produces, to solve the flatness problem of chase.
It should be noted that, the above is not the restriction to technical scheme of the present invention, and under the prerequisite not departing from creation design of the present invention, any apparent replacement is all within protection scope of the present invention.
