【具体实施方式】
下面结合附图和实施例，对本发明作进一步的详细描述。特别指出的是，以下实施例仅用于说明本发明，但不对本发明的范围进行限定。同样的，以下实施例仅为本发明的部分实施例而非全部实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
实施例一，请参阅图1和图2，本实施例提供一种用于背光模组的背板组件，该背光模组包括光学部材和背板组件，而背板组件又包括第一拼接件1和第二拼接件2。很容易理解，光学部材和背板组件是本实施例中背光模组的主要组成部分，而不是所有组成部分，在其它实施例中，背光模组的组成部分也可以根据需要进行调整，本发明对此不作限定。下面介绍背板组件的具体结构。
具体而言，第一拼接件1设有第一容置槽3，第二拼接件2设有第二容置槽4，第一容置槽3和第二容置槽4分别用于容置光学部材相邻的两侧边。由于光学部材一般为板状结构，因此第一容置槽3和第二容置槽4可以相应设置成U型，以配合容置光学部材。由于光学部材等采用本领域技术人员所熟知的现有技术，因此这里不作赘述。
这里需要重点说明的是第一拼接件1和第二拼接件2的连接方式。在本实施例中，两者是“枢接”的关系，即：第一拼接件1的一端和第二拼接件2的一端通过枢接的方式连接在一起，两者之间可以绕枢接的端进行旋转。这样，通过旋转便可将第一拼接件1旋转至第二容置槽4内，或者将第二拼接件2旋转至第二容置槽3内。于是，在组装前运输的过程中，便可将第一拼接件1和第二拼接件2通过折叠的方式“结合”在一起，以减小每个背板组件所占用的运输空间，从而减少其运输体积，以提高每次运输的数量和重量，从而降低运输成本。
本发明第一实施例通过枢接的方式连接第一拼接件1和第二拼接件2，可以在运输时将两者折叠起来以减小运输体积，从而提高运输效率并进一步降低运输成本。
实施例二，请参阅图3和图4，在本实施例中，背光模组包括但不限于光学部材和背板组件。其中，光学部材可以采用现有技术的光学部材，在此不作赘述，下面详细介绍背板组件的具体结构。
在本实施例中，背板组件包括两个第一拼接件10和两个第二拼接件20，四个拼接件通过首尾相接的方式组成完整的背板组件。很容易理解，在其它实施例中，也可以采用其它数量的拼接件通过首尾相接的方式来组成背板组件，例如6个第一拼接件10和4个第二拼接件20，只要使得组合之后背板组件的形状和大小均与光学部材相匹配即可，本发明不对拼接件的数量作任何限定。本实施例中仅以“两个第一拼接件10和两个第二拼接件20”这种情况为例进行说明。
首先介绍一下第一拼接件10和第二拼接件20的具体结构。请参阅图5，第一拼接件10包括第一底板101、第一挡墙102、第一侧壁103以及第一枢接部104。其中，第一底板101与光学部材的下表面相抵接以支撑该光学部材，第一挡墙102抵靠光学部材的上表面以压盖该光学部材。第一侧壁103用于连接第一底板101和第一挡墙102，具体来说，第一侧壁103的底端与第一底板101相连接，第一侧壁103的顶端与第一挡墙102相连接。第一枢接部104为分别设于第一底板101和第一挡墙102上的第一通孔（未标示）。
可以看出，第一底板101、第一挡墙102和第一侧壁103共同形成第一容置槽11，该容置槽用于容置光学部材的第一侧边。本领域的技术人员很容易理解，第一容置槽11具有容置并定位光学部材的作用。
第二拼接件20的基本结构与第一拼接件10类似。具体来说，第二拼接件20包括第二底板201、第二挡墙202、第二侧壁203以及第二枢接部204。其中，第二底板201用于支撑光学部材的下表面，第二挡墙202用于抵靠光学部材的上表面。第二侧壁203用于连接第二底板201和第二挡墙202，第二枢接部204为分别设于第二底板201和第二挡墙202上的第二通孔（未标示）。
其中，第二底板201、第二挡墙202和第二侧壁203共同形成第二容置槽21，该容置槽用于容置光学部材的第二侧边（即光学部材中与前述第一侧边相邻的侧边）。显然，第二容置槽21也具有容置和定位光学部材的作用，且第二容置槽21与第一容置槽11相配合，分别容置并固定光学部材的相邻侧边。为了配合光学部材并起到固定和保护的作用，第一容置槽11和第二容置槽21均可以设置成U型，由于属于本领域技术人员所熟知的内容，这里不作赘述。
值得一提的是，无论是第一底板101、第一挡墙102和第一侧壁103，还是第二底板201、第二挡墙202和第二侧壁203，其具体的结构均可以灵活设置。以第一侧壁103为例，在本实施例中，第一侧壁103为一块一体成型的侧板，显然，在其它实施例中，第一侧壁103也可以是多个间隔设置的立柱，且每一个立柱的两端分别与第一底板101和第一挡墙102相连接。再以第二挡墙202为例，其作用是抵靠光学部材的上表面，不难理解的是，其具体形状可以是长方形、三角形，也可以是圆弧形，还可以是多个间隔设置的条状面板。因此，在不影响其功能的前提下，本发明不对任何一底板、挡墙或侧壁的大小、形状等特征进行限定，相关技术人员完全可以根据需要进行灵活设置。
在介绍了第一拼接件10和第二拼接件20的结构之后，接下来则说明一下两者的连接方式。第一拼接件10和第二拼接件20通过枢接的方式相连接，即第一拼接件10的一端和第二拼接件20的一端通过第一枢接部104和第二枢接部204的配合实现枢接。在本实施例中，通过铆钉或螺钉贯穿第一通孔和第二通孔，以实现两者之间的枢接，由于“使用铆钉或螺钉贯穿通孔”进行枢接是本领域技术人员很容易理解的内容，故这里不作赘述。
值得一提的是，第一通孔和第二通孔的形状、大小等特征均可以根据具体情况进行灵活的设置，而连接方式也不限于铆钉或螺钉。例如，将第一通孔和第二通孔的形状均设置为方形，然后再以过盈配合的方式插入一个相应设置的方形定位住，只要保证第一拼接件10和第二拼接件20能够折叠在一起、以及形成90度夹角这两种状态即可。同样的，在制作的时候，还可以在挡墙和底板上设置多个通孔，以便工作人员在具体操作的时候可以选择最合适的通孔进行枢接，本发明对此不作限定。
请参阅图6，在第一侧壁103或/和第二侧壁203邻近枢接端的位置设有导槽205，以允许或方便第一拼接件10和第二拼接件20之间相对旋转。该导槽205为拼接件的侧壁上预设的中空区域，能够允许另一拼接件的枢接部按一定的轨迹自由旋转。需要指出的是，导槽205的具体结构可以灵活设置，本发明对导槽205的结构等特征不进行限定。
特别需要注意的是，第一枢接部104和第二枢接部204并不限于上述的设置方式，本领域技术人员很容易在不付出创造性劳动的情况下想出其他方式：譬如将第一枢接部104设置成分别位于第一底板101和第一挡墙102上的通孔，将第二枢接部204设置成分别位于第二底板201和第二挡墙202上的凸块，从而使第一拼接件10和第二拼接件20通过该通孔和凸块的配合进行枢接；也可以将第一枢接部104设置成分别位于第一底板101和第一挡墙102上的凸块，将第二枢接部204设置成分位于于第二底板201和第二挡墙202上的通孔，从而使第一拼接件10和第二拼接件20通过该凸块和通孔的配合进行枢接；还可以将第一枢接部104设置成位于第一底板101（或第一挡墙102）上的定位柱，而将第二枢接部204设置成位于第二底板201（或第二挡墙202）上的容置槽，通过该定位柱和容置槽的配合来实现枢接。在可以实现枢接功能的情况下，本发明不对第一枢接部104和第二枢接部204的具体设置方式作限定。
如图4所示，组装前运输的时候，可以将第二拼接件20旋转至第一容置槽11内，此时，第二底板201和第二挡墙202夹设于第一底板101和第一挡墙102之间。很容易理解，也可以采取其他“折叠”方式，例如将第一拼接件10旋转至第二容置槽21内，此时，第一底板101和第一挡墙102夹设于第二底板201和第二挡墙202之间；或者以“交错”的方式折叠，例如第一底板101和第二挡墙202夹设于第二底板201和第一挡墙102之间。以上几种方式均可以通过枢接以实现折叠的功能，本领域技术人员在不付出创造性劳动的情况下，还可以想到其他折叠方式，故本发明不对其枢接和折叠的具体方式进行限定。
在本发明第二实施例中，通过枢接的方式连接第一拼接件10和第二拼接件20，使得背板组件在组装前可以采用折叠的方式进行运输，从而达到减小运输体积的目的，并进一步提高了运输效率、减少运输成本。
在本发明的第三实施例中，提供了一种背光模组，该背光模组包括光学部材和前文所述的背板组件。其中，光学部材包括层叠设置的导光板和光学膜片。由于背板组件的具体结构等内容已在前面实施例中进行了详细的介绍，故在此不作赘述。
在本发明的第四实施例中，提供了一种液晶显示装置，该液晶显示装置包括液晶面板和如前所述的背光模组。由于前文中已经对背光模组和背板组件进行了详细的说明，这里不作赘述。
不难理解，无论是背光模组还是液晶显示装置，由于其采用了本发明第一实施例或第二实施例中的背板组件，因此，在其组装之前，均可以通过折叠背板组件的方式来减小运输体积，并进一步降低成本。
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。
