具体实施方式
请参阅图1，本发明实施方式提供一种背光模组的背板10，包括：第一承载板11、与第一承载板11相对设置的第二承载板12、连接第一承载板11与第二承载板12的多个支撑部13。第一承载板11位于第二承载板12的一侧，并与第二承载板12形成间隔区域17。支撑部13设于间隔区域17内。第一承载板11与第二承载板12朝向间隔区域17的一侧设有连接基体(图未示)。支撑部13包括第一支撑架131及与第一支撑架131交叉旋转连接的第二支撑架 132。第一支撑架131的两端分别与第一承载板11及第二承载板12的连接基体可拆卸连接。第二支撑架132的两侧分别与第一承载板11及第二承载板12的连接基体可拆卸连接。第一支撑架131与第二支撑架132相对旋转以调节所述第一承载板11与第二承载板12之间的间隔区域17的宽度。
本发明通过简单的支撑部13连接第一承载板11与第二承载板12来设计具有中空的背板10结构，从而减少材料成本的投入。此外，利用第一支撑架131及第二支撑架132的相对旋转来调节第一承载板11与第二承载板12之间的间隔区域17的宽度，从而支撑不同宽度的条形液晶面板50。所述背板10结构既能够有效地使无缺陷的条形液晶面板加以二次使用，减少材料的损失，又能够实现对不同宽度的条形液晶面板50的支撑。
如图2和图3所示，每两个相邻的支撑部13之间连接有一个固定架15。本实施例中，固定架15的两端通过螺钉可拆卸地固定于支撑部13上。这样有助于当固定架15破损或不能被使用时可简便地进行拆卸并替换。在其他实施例里，固定架15也可以通过卡持件、螺丝或者电焊连接于支撑部13上，具体根据实际情况灵活设计。背板10通过固定架15将多个支撑部13相互连接，使得第一支撑架131与第二支撑架132分别与第一承载板11和第二承载板12实现三点固定，从而有效地提高了背板10结构的稳定性。
本实施例中，第一支撑架131和第二支撑架132通过轴承转动连接，固定架15的两端分别固定于每两个支撑部13的轴承上。所述轴承可以使得第一支撑架131相对第二支撑架132发生任意角度的旋转。通过旋转不同的角度并将第一支撑架131和第二支撑架132固定于第一承载板11及第二承载板12上，这可以实现不同宽度的间隔区域17，从而用于承载不同宽度的条形液晶面板50。在其他实施例中，第一支撑架131和第二支撑架132也可通过其他转动组件连接，可以根据实际情况设计。
本发明的第一种实施例，第一承载板11及第二承载板12的连接基体为一排等间距的固定孔14。第一承载板11朝着第二承载板12方向的一侧设有固定孔14。第二承载板12朝着第一承载板11方向的一侧也设有固定孔14。固定孔14由冲压形成，固定孔14的直径均一。固定孔14的制作工艺简单方便，有利于工作人员操作。
如图3所示，连接部13的数量为3个。在其他实施例中，所述连接部13的数量根据实际情况设计。第一支撑架131及第二支撑架132的两侧的末端分别设有一个螺孔16，螺孔16与固定孔14对准连接。具体的，螺孔16的直径和第一承载板11及第二承载板12的固定孔14直径一致。第一个支撑部13的第一支撑架131和第二支撑架132的一端的螺孔16分别与第一承载板11的第一端的第一个固定孔14及第三个固定孔14对齐，并通过螺丝锁紧。第一个连接部13的第一支撑架131和第二支撑架132的另一端的螺孔16分别与第二承载板12相对第一承载板11同一端的第一个固定孔14及第三个固定孔14对齐，并通过螺丝锁紧。依此类推，将第二个支撑部13和第三个支撑部13依次与第一承载板11和第二承载板12上的固定孔14锁紧连接。在其他实施中，当第一支撑架131与第一承载板11锁付的螺孔16和第二支撑架132与第一承载板11锁付的固定孔14之间的距离减小，即第一支撑架131与第二支撑架132张开的角度减小，第一承载板11和第二承载板12之间的宽度就增大，即间隔区域17的宽度越大。此外，所述第一支撑架131和第二支撑架132的螺孔16也可以通过销钉或螺钉等分别与所述第一承载板11及第二承载板12的固定孔14可拆卸连接。通过在第一支撑架131与第二支撑架132的两端设置螺孔16，再利用螺钉、螺丝或者销钉与第一承载板11和第二承载板12连接，所述背板结构稳定性强。此外，当连接部13的数量为3个时，第一支撑架131与第二支撑架132的螺孔16的数量为12个，这显著地减少了第一承载板11与第二承载板12的连接材料，从而节约了材料成本的投入。
本发明的第二种实施例，连接组件为一排等间距的磁铁。第一承载板11朝向第二承载板12方向的一侧固接上磁铁。第二承载板12朝向第一承载板11方向的一侧也固接上磁铁。所述的磁铁的大小均一。磁铁的大小及形状根据实际情况设计。第一支撑架131和第二支撑架132通过转轴相互交叉连接。此外，第一支撑架131和第二支撑架132的两侧的末端分别固接上所述磁铁。本实施例中，为了减小背板材料的投入成本，磁铁的大小和形状与第一承载板11和第二承载板12上的磁铁的大小形状一致。且所述支撑部13的数量为3个。第一个支撑部13的第一支撑架131和第二支撑架132的一端的磁铁分别与第一承载板11的一端的第一个磁铁及第三个磁铁对齐，并相互吸附贴紧。 第一支撑架131和第二支撑架132的另一端的磁铁分别与第二承载板12相对第一承载板11同一端的第一个磁铁和第三个磁铁对齐，并相互吸附贴紧。依此类推，第二个支撑部13和第三个支撑部13依次与第一承载板11和第二承载板12吸附贴紧。显然，在其他实施例中，当减小第一支撑架131与第一承载板11磁铁吸附的位置和第二支撑架132与第一承载板11磁铁吸附的位置之间的距离，即减小第一支撑架131与第二支撑架132张开的角度，第一承载板11和第二承载板12之间的宽度就相对增大，即间隔区域17的宽度越大。
如图4所示为一种背光模组，包括背板10、反射片20、导光板30和光学膜片40。反射片20、导光板30与光学膜片40依次叠加设置并收容于背板10中。具体的，根据反射片20、导光板30与光学膜片40的宽度调节第一支撑架131与第二支撑架132的旋转角度。将调整好旋转角度的第一支撑架131与第二支撑架固定于第一承载板11与第二承载板12之间。反射片20、导光板30与光学膜片40的宽度比第一承载板11和第二承载板12之间的间隔区域17的宽度大。因此，将反射片20、导光板30与光学膜片40层叠放置于第一承载板11与第二承载板12形成的间隔区域17内，并利用第一承载板11和第二承载板12支撑住反射片20、导光板30与光学膜片40的边缘区域。通过背板10可以实现支撑不同宽度的反射片20、导光板30与光学膜片40。
如图5所示为一种条形显示器，包括条形液晶面板50及背光模组，条形液晶面板50设于背光模组出光的一侧。条形液晶面板50通过背光模组实现显示。条形液晶面板50包括依次层叠于所述背光模组的下偏光片、薄膜晶体管阵列基板、彩膜基板、及上偏光片。将条形液晶面板50层叠于已收容于背板的第一承载板11与第二承载板12之间的背光模组。第一承载板11与第二承载板12之间的宽度及承载部13的数量，可以根据背光模组与条形液晶面板50的宽度及强度决定。本实施例中，承载部13的数量为3个。根据条形液晶面板50的宽度设置第一支撑架131与第二支撑架132的旋转角度，并固定于第一承载板11和第二承载板12。这样，第一承载板11朝向第二承载板12的端面与所述第二承载板12朝向所述第一承载板11的端面之间的距离小于所述条形液晶面板50的宽度。反射片20、导光板30、光学膜片40及条形液晶面板50的大部分区域放置于第一承载板11与第二承载板12连接的间隔区域17 内，并利用第一承载板11和第二承载板12支撑住反射片20、导光板30与光学膜片40及条形液晶面板50的边缘区域。通过背板10结构可以支撑或承载不同宽度的条形液晶面板50。
本发明实施例中，通过在第一承载板11和第二承载板12之间设置支撑部13，支撑部13包括第一支撑架131和与第一支撑架131交叉旋转连接的第二支撑架132，从而构建具有高稳定性的背板10。利用第一支撑架131和第二支撑架132的一端的螺孔16分别与第一承载板11的不同位置的固定孔14对齐并锁紧以及第一支撑架131和第二支撑架132的另一端的螺孔16分别与第二承载板12的一个固定孔14对齐并锁紧，可控地锁紧不同的固定孔14位置的距离来达到不同的支撑高度，从而实现承载不同宽度的条形液晶面板50。背板10结构简单，稳定性强，可减小材料成本的投入。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
