【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明一实施例背板组件的第一支架和第二支架的部分结构示意图；
图2是图1所示背板组件的第一支架和第二支架安装后的正面结构示意图；
图3是图1所示背板组件的第一支架和第二支架安装后的背面结构示意图；
图4是本发明一实施例背光模组的背板组件的立体结构示意图；以及
图5是图4所示背板组件组装完成后的结构示意图。
【具体实施方式】
请参阅图1，图1是本发明一实施例背板组件的第一支架和第二支架的部分结构示意图。
在本实施例中，背板组件包括但不限于一个或多个第一支架1和第二支架2。
具体而言，第一支架1上设置有卡扣11、定位槽12以及形变部13等。卡扣11包括连接第一支架1的底板的连接部111以及连接该连接部111的压合部112。优选地，连接部111可以垂直于第一支架1的底板10设置，而压合部112则可以平行于第一支架1的底板10设置，当然，连接部111和压合部112与底板10之间也可以呈一预定的角度设置，在此不作限定。定位槽12设置于形变部13上，形变部13包括弹片131和通孔132，弹片131一端固定在底板10上，另一端靠近通孔132且可以沿垂直底板10方向上下移动。图1只是给出了第一支架1的第一端的结构示意图，而第二端（图未示）的结构与第一端基本相同，在此不作赘述。
对应地，第二支架2上设置有卡合端21以及设于卡合端21上的底面20，卡合端21上还设置有卡孔211和凸起部212。卡孔211进一步包括相互连通且开口大小不同的第一卡孔2111和第二卡孔2112，如图1所示，第一卡孔2111的开口大小略大于压合部112的大小，优选地，第一卡孔2111的开口大小与压合部112的大小相匹配以允许压合部112自由贯穿第一卡孔2111，而第二卡孔2112的开口大小与连接部111的厚度相匹配以允许连接部111在第一卡孔2111和第二卡孔2112之间自由滑动，换而言之，在安装时，压合部112首先贯穿第一卡孔2111并突出于第二支架2的底面20，接着，连接部111经由第一卡孔2111滑入第二卡孔2112，使压合部112压合于卡合端21的底面20以实现卡合连接。图1中卡扣11为四个，卡孔211也为四个，但在实际中只需保证卡扣11与卡孔211为一一对应配合，卡扣11与卡孔211的具体数目可以根据背板组件结构的稳定性需求而定，在此不作限定。
对第一支架1和第二支架2进行安装的具体操作过程中，压合部112从第二支架2的底面20的底部贯穿第一卡孔2111，使连接部111的侧面正对着第二卡孔2112。在此过程中，凸起部212挤压弹片131，具体可以挤压弹片131位于定位槽12和通孔132之间的部分上以使弹片131靠近通孔132一端往底板10背面弯曲变形。然后推动第二支架2往第一支架1的方向运动，使连接部111进入第二卡孔2112，直至连接部111部分或全部容纳于第二卡孔2112里。此时，压合部112的底部压住第二支架2的底面20，凸起部212则从弹片131上完全进入定位槽12之中。当然，凸起部212初始接触第一支架1的位置也可以在通孔132上，此时凸起部212部分接触弹片131，弹片131靠近通孔132一端受力而沿底板10弯曲变形，再推动第二支架2使凸起部212完全进入定位槽12之中。优选地，凸起部212与定位槽12之间的配合为过盈配合，以进一步将凸起部212紧密地固定在定位槽12中，从而有效地防止了第一支架1和第二支架2之间的相对滑动。此外，本实施例也可以设置第一卡孔2111和第二卡孔2112按不同的方向进行排列，使压合部112从第二支架2的底面20的底部穿过第一卡孔2111后，可以推动第二支架2向其他方向运动，使连接部111进入第二卡孔2112即可，在此不作赘述。
请结合图1参阅图2和图3，图2是图1所示背板组件的第一支架和第二支架安装后的正面结构示意图，图3是图1所示背板组件的第一支架和第二支架安装后的背面结构示意图。
当需要拆卸背板组件时，可用工具穿过通孔132，用工具抵住弹片131抵接第二支架2的一面，朝背离第二支架2的方向拉动弹片131，这样，凸起部212可以从定位槽12中脱离出来，此时，只需再往背离第一支架1的方向拉动第二支架2直至连接部111抵住第一卡孔2111，再垂直向上提动第二支架2，就可以把第一支架1和第二支架2拆卸开来。
本发明实施例通过在背板组件的第一支架1上设置卡扣11、定位槽12以及形变部13，在第二支架2上设置卡孔211和凸起部212。通过卡扣11和卡孔211、凸起部212和定位槽12的配合，实现了拼接式背板组件的安装。本发明实施例不需要用到螺丝对背板组件进行安装固定，也不需要用到人工来进行螺丝的装配，有效地降低了生产成本，有利于自动化生产。
请参阅图4和图5，图4是本发明一实施例背光模组的背板组件的立体结构示意图，图5是图4所示背板组件组装完成后的结构示意图。
在本实施例中，该背光模组包括但不限于光学部材和上述的背板组件等。
如前所述，背板组件包括第一支架41、第二支架42和第三支架43。
其中，第一支架41和第二支架42的具体结构请参阅前面实施例的相关描述，在本技术领域人员容易结合理解的范围内，在此不再赘述。
进一步而言，本实施例的第一支架41上包括第一底板410和第一侧壁411，而第一侧壁411远离第一底板410的一端设有第一挡墙4111。
而第二支架42为两个且均包括第二底板420和第二侧壁421，第二侧壁421远离第二底板420的一端设有第二挡墙4211，第一支架41与第二支架42采用前面实施例描述的配合方式进行连接。
第三支架43也可以设置第三底板、第三侧壁和第三挡墙等，其可以通过卡接等方式连接到两个第二支架42上，在此不作限定。
本实施例背光模组的具体配合方式如下：第一支架41的第一底板410和第一支架42的第二底板420用于支撑光学部材，第一侧壁411和第二侧壁绕421绕光学部材的侧边设置。通过这种方式将光学部材稳定地安置在背板组件上。本发明实施例的背光模组的背板组件组装完成后，其整体结构如图5所示。
请继续参阅图4和图5，本发明实施例还提供一种配备上述背光模组的液晶显示装置，其中，通过第一挡墙4111、两个第二挡墙4211以及第三支架43的第三挡墙的配合以固定光学部材和承载液晶面板，在本技术领域人员容易理解的范围内，不作赘述。
本发明实施例通过在背板组件的第一支架41上设置卡扣、定位槽以及形变部，在第二支架42上设置卡孔和凸起部，通过卡扣和卡孔、凸起部和定位槽的配合，实现了拼接式背板组件的安装，而不需要用到螺丝对背板组件进行安装固定，也不需要用到人工来进行螺丝的装配，能够有效地降低生产成本，有利于自动化生产。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
