【附图说明】

图2是多个图１所示拼接部件之间的连接方式示意图；
图3是图２所示任意两个拼接部件之间的连接方式示意图；以及
图4是本发明实施例多个背板组件的组合方式示意图。
【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。基于本发明中的实施例，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他实施例，都属于本发明保护的范围。
请一并参阅图1和图3，在本发明第一实施例中，背板组件包括至少两个拼接部件40且均设于光学部材的同一侧边。由于背板组件的多个拼接部件40均具有相同的结构，故这里只选用其中一个进行说明。
一个拼接部件40用于与另一个拼接部件40相连接的拼接单元。在本实施例中，可以通过调整拼接部件40的数量来改变背板组件的长度，使得该背板组件的长度与光学部材的侧边的长度相匹配。举例来说，假如光学部材的侧边的长度为20厘米，而一个拼接部件40长度为5厘米，则可以通过4个拼接部件40组装成一个背板组件以配合光学部材的对应侧边即可。
下面具体说明拼接部件40的结构以及两个拼接部件40的连接方式。
拼接部件40包括与光学部材的侧边对应设置的侧墙30以及用于抵接光学部材的固定板31，侧墙30和固定板31相连接。值得一提的是，在本实施例中，固定板31为支撑液晶面板的挡墙，在其它实施例中，固定板31也可以为支撑光学部材的底板，也就是说，固定板31可以用于支撑光学部材或用于支撑液晶面板，本发明对此不作限定，这里仅以固定板31为支撑液晶面板的挡墙为例进行说明。具体地说，当固定板31为用于支撑光学部材的底板时，其基本结构与此相似，只是“上下相反”而已，由于这点属于本领域普通技术人员很容易理解的内容，故在此不做赘述。
拼接部件40进一步包括设于拼接部件40一端的第一卡合部和第一定位部，以及设于拼接部件40另一端的第二卡合部和第二定位部。拼接部件40的第一卡合部与另一个拼接部件40的第二卡合部卡合连接，且拼接部件40的第一定位部与另一个拼接部件40的第二定位部相配合，以防止拼接部件40和另一个拼接部件40之间脱离连接。或者是拼接部件40的第二卡合部与另一个拼接部件40的第一卡合部卡合连接，且拼接部件40的第二定位部与另一个拼接部件40的第一定位部相配合，以防止拼接部件40和另一个拼接部件40之间脱离连接。
具体来说，第一卡合部为设于侧墙30的凸块10，第一定位部为设于固定板31的凸起11，第二卡合部为设于侧墙30的卡孔20，第二定位部为设于固定板31的定位槽21。其连接方式为：凸块10贯穿卡孔20，凸起11收容于定位槽21（显然，这里的连接方式为两个拼接部件40之间的连接，而不是指同一拼接部件40中的凸块10与卡孔20、或凸起11与定位槽21）。
在本实施例中，凸块10与卡孔20可以采用过盈配合的方式进行连接，凸起11与定位槽21也可以采用过盈配合的方式进行连接。在其它实施例中，凸块10与卡孔20、以及凸起11与定位槽21均可以采用其它方式卡合连接，譬如通过螺钉或铆钉等固定连接，本发明对此不作限定。
值得一提的是，第一卡合部、第一定位部、第二卡合部和第二定位部均可以灵活设置，只要能够相互配合以固定连接两个拼接部件40即可。例如，在其它实施例中，第一卡合部可以为设于侧墙30的卡孔20，第一定位部可以为设于固定板31的凸起11，第二卡合部可以为设于侧墙30的凸块10，第二定位部可以为设于固定板31的定位槽21，而其具体连接方式也是凸块10贯穿卡孔20、且凸起11收容于定位槽21。很容易理解，关键是通过第一卡合部、第一定位部、第二卡合部和第二定位部的配合来连接两个拼接部件40，而其具体位置和顺序等特征均可以灵活设置，本发明对此不作限定。
正如前面所说的，固定板31还可以是用于支撑光学部材的底板，这里简单的说明一下：很容易理解，当固定板31是用于支撑光学部材的底板时，凸起11设置在底板的一端，而定位槽21则设置在底板的另一端，其结构和功能等特征并没有改变，因此这里不作赘述。
为了更好的实现连接的效果，拼接部件40还包括第一定位孔12和第二定位孔22。其中，第一定位孔12位于拼接部件40的一端，且与凸块10间隔设置；第二定位孔22于拼接部件40的另一端，且与卡孔20间隔设置。一个拼接部件40的第一定位孔12与另一个拼接部件40的第二定位孔22之间采用螺钉或铆钉贯穿以进一步固定连接。换句话说，当两个拼接部件40相连接时，第一定位孔12与第二定位孔22是“对齐”的，故可以通过插入螺钉或铆钉进行固定。
值得一提的是，第一定位孔12和第二定位孔22的形状、大小等具体特征均可以根据实际需要进行灵活设置，本发明对此不作限定。另外，本领域技术人员也很容易想到，除了螺钉或铆钉外，还可以通过其它定位柱来进行连接。例如，第一定位孔12和第二定位孔22均可以设置成方形或三角形，然后插入相应的定位柱（可以是过盈配合）进行定位。
另外，在其它实施例中，可以将第一定位孔12（或第二定位孔22）设置成与拼接部件40一体成型的定位柱，从而直接与另一拼接部件40的第二定位孔22（或第一定位孔12）进行卡合连接，以进一步固定两个拼接部件40。因此，对于第一定位孔12和第二定位孔22的特征而言，本领域技术人员在不付出创造性的前提下所想到的其它设置方式均属于本发明的保护范围。
请进一步参阅图4，在本实施例中，背板组件为多个，且多个背板组件首尾依次相连接，以形成一整体的背板组件。其中，背板组件还包括支撑单元50，该支撑单元50设于多个背板组件之间并用于支撑光学部材。
值得注意的是，支撑单元50并非本发明的必要技术特征，故支撑单元50的任何结构、数量等特征均不构成对本发明的限定。例如，支撑单元50可以为间隔设置的条状长坂，也可以采取其他设置方式，如一体成型的底板、间隔设置的支撑住等；其排列方式可以灵活设置，除了间隔设置外，还可以是“十”字型或“井”字型等。总而言之，本领域技术人员在不付出创造性的情况下所想到的其它设置方式均属于本发明的保护范围。
在本发明第一实施例中，背板组件是由至少两个拼接部件组成的，通过这种可拆卸的组装方式，背板组件可以拆开运输以减小运输体积，并降低运输成本。另外，通过调整拼接部件的数量可以形成特定的背板组件，且多个拼接部件40均可以采用同一模具制得，故本发明实施例可以达到共用模具的效果，从而降低模具成本。
本发明的第二实施例还提供一种拼接部件的制作模具，该制作模具用于制作前一实施例中的拼接部件，且多个拼接部件用于拼接成前一实施例中的背板组件。由于拼接部件和背板组件的具体结构等特征均在前文中进行了详细的说明，故在此不作赘述。
采用本发明第二实施例中的制作模具，可以用统一的模具制作出前一实施例中背板组件的多个拼接部件，接着通过改变拼接部件的数量来调整背板组件的长度。通过共用模具的方式，本发明第二实施例的制作模具能够有效的降低模具成本。
本发明的第三实施例还提供一种背光模组，该背光模组配备有第一实施例中的背板组件，由于背板组件的具体结构等特征均在前文中进行了详细的说明，故在此不作赘述。
本发明的第四实施例还提供一种显示装置，该显示装置配备有第一实施例中的背板组件，由于背板组件的具体结构等特征均在前文中进行了详细的说明，故在此不作赘述。
在本发明的第三和第四实施例中，由于均配备有第一实施例中的背板组件，因此可以达到减小运输体积和降低运输成本的效果。同时，由于可以共用模具，该背板组件还可以节省模具成本。很容易理解，这将有效的节省背光模组和显示装置的总成本。
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。
