Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to backlight module and framework and its embodiment of retaining element, structure, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
Please refer to Fig. 1 and Fig. 2.Fig. 1 and Fig. 2 are respectively the exploded perspective view and the stereographic map of backlight module 100 according to an embodiment of the invention.One framework 110 and a retaining element 150 are arranged in the backlight module 100, be used for optical sheet 180 is stably fixed, avoid tilting, being inverted or bump makes optical sheet 180 displacements because of backlight module 100.Below with regard to each element, describe its structure and function one by one in detail.
One microscope carrier 120 and two stopper slots 140 are arranged in the framework 110.Microscope carrier 120 picks up the ears 182 in order to one of bearing optical sheet 180.Two stopper slots 140 lay respectively at the both sides of microscope carrier 120, and next-door neighbour's microscope carrier 120.
Retaining element 150 can be subdivided into one and cover portion 160 and two fixed parts 170.Wherein, two fixed parts 170 are connected to the both sides of the portion of covering 160, in order to be fastened among the stopper slot 140.
When optical sheet 180 pick up the ears 182 when being placed on the microscope carrier 120, cover portion 160 can repeatedly put pick up the ears 182 and microscope carrier 120 on.Simultaneously, fixed part 170 engages with stopper slot 140, and then fixed optics sheet 180 moving in vertical direction.
Fixed part 170 is used for being fastened in the stopper slot 140.For instance, the width of fixed part 170 slightly can be equaled the width of stopper slot 140, make fixed part 170 to be stuck in just among the stopper slot 140.Perhaps, fixed part 170 also can have an elastic construction, for example spring or shell fragment, make fixed part 170 can with stopper slot 140 interlocks.In the present embodiment, fixed part 170 has a shell fragment 172, is installed in the bottom of fixed part 170, on the medial surface that is connected to stopper slot 140.There is tolerance unavoidably in the size of retaining element 150.If the height of retaining element 150 is bigger than normal, then with backlight module and liquid crystal panel assembling the time, can interfere with liquid crystal panel, serious meeting causes fragmentation.Being provided with of shell fragment 172 can address this problem.Shell fragment 172 is installed in the bottom of fixed part 170, when making fixed part 170 and stopper slot 140 interlocks, goes back the interference that may exist between available buffer retaining element and the liquid crystal panel.
Each stopper slot 140 all comprises a vertical component effect 142 and a horizontal part 144.Vertical component effect 142 is perpendicular to the bottom surface 122 of microscope carrier 120, and the top 146 of vertical component effect 142 connects the bottom surface 122 of microscope carrier 120.Horizontal part 144 is parallel with the bottom surface 122 of microscope carrier 120, and an end of horizontal part 144 connects the bottom 148 of vertical component effect 142.In other words, the shape of stopper slot 140 presents L shaped.The fixed part 170 of retaining element 150 also cooperates the shape of stopper slot 140, is bent into L shaped.
Also has a fixture on the microscope carrier 120, in order to fixedly to pick up the ears 182 position.Specifically, fixture can be a projection 130, and picks up the ears 182 to have a hole 184, and hole 184 can be passed for projection 130.Thus, when optical sheet 180 was seated in the framework 110, the projection 130 on the microscope carrier 120 passed the hole 184 of picking up the ears on 182, and then the moving horizontally of restriction optical sheet 180.
Wherein, the shape of projection 130 can be shapes such as circle, ellipse, square or triangle.In the present embodiment, projection 130 be shaped as circle because circular edge does not have knuckle, can avoid clashing into and pick up the ears 182 hole 184 to make optical sheet 180 break.
In addition, when when assembling, the hole 184 of picking up the ears on 182 can be socketed on the projection 130, so the shape in hole 184 also cooperates the shape of projection 130.In the present embodiment, hole 184 be shaped as long hole shape, make that hole 184 is socketed on the projection 130 after, the space that still has a little front and back to move avoids that optical sheet 180 is locked.
In addition, cover on the position of corresponding fixture in the portion 160 and be formed with a fastener, fastener can engage with fixture.In the present embodiment, fastener is a recess 162, and its position, shape and size all cooperate projection 130.So when the portion of covering 160 be seated in pick up the ears 182 and microscope carrier 120 on the time, recess 162 can pass for projection 130.
By the foregoing description as can be known, the fixed part 170 of retaining element 150 is fastened in the stopper slot 140, make cover portion 160 with optical sheet 180 pick up the ears 182 be fixed on the microscope carrier 120 the moving of restriction optical sheet 180 vertical direction.Simultaneously, see through projection 130 pass optical sheet 180 pick up the ears on 182 hole 184 and cover recess 162 in the portion 160, and then with the stationkeeping of optical sheet 180 horizontal directions.Make optical sheet 180 firmly be housed among the framework 110, can not be inverted, be sidelong or be clashed into and displacement because of backlight module 100.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
