【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
参阅图1，图1是本发明第一实施例的背板在正常使用状态下的俯视图。在本实施例中，背板包括第一支架110、第二支架120、第三支架130、铝挤140以及辅助支架150。
在本实施例中，第一支架110和第二支架120以及第三支架130和铝挤140分别为长条形结构，并以拼接方式形成背板的外框架。其中，背板的外框架在正常使用状态形成一矩形结构。具体来说，第一支架110和第二支架120之间平行间隔设置，第三支架130和铝挤140之间平行设置。第三支架130分别与第一支架110和第二支架120的一端垂直连接，铝挤140分别与第一支架110和第二支架120的另一端垂直连接。辅助支架150的两端分别与第一支架110和第二支架120连接，辅助支架150与第三支架130和铝挤140平行。其中，辅助支架150可以设置一个或多个。
在本实施例中，优选第一支架110的一端与第三支架130的一端、第一支架110的另一端与铝挤140的一端、第二支架120的一端与第三支架130的另一端、第二支架120的另一端与铝挤140的另一端分别通过转动结构160连接，以使相邻的第一支架110和第二支架120与第三支架130和铝挤140可以转动机构160为轴进行相对转动，以使得背板可在正常使用状态和折叠状态之间进行切换。其中，转动机构160可以由螺钉、铆钉、螺栓等任何适当的固定件实现。
参阅图2，图2是本发明第一实施例的背板在折叠状态下的俯视图。相比与图1，在从正常使用状态切换到折叠状态时，可取下背板的辅助支架150，并使得第一支架110和第二支架120与第三支架130和铝挤140以转动机构160为轴进行转动，进而使得背板的外框架从矩形结构变为平行四边形结构。因此，背板在折叠状态下的占用空间小于在正常使用状态下的占用空间。
参阅图3，图3是本发明第二实施例的背板在正常使用状态下的俯视图。在本实施例中，背板包括第一支架210、第二支架220、第三支架230、铝挤240以及辅助支架250。
在正常使用状态，第一支架210和第二支架220平行设置，第三支架230和铝挤240平行设置，并以拼接方式形成背板的外框架。辅助支架250的两端分别与第一支架210和第二支架220连接，辅助支架250与第三支架230和铝挤240平行。其中，辅助支架250可以设置一个或多个。
本实施例与第一实施例的不同之处在于，第一支架210包括第一主体部211和自第一主体部211的一端垂直延伸的第一延伸部212，第二支架220包括第二主体部221和自第二主体部221的一端垂直延伸的第二延伸部222。
其中，第一延伸部212与第三支架230的一端、第三支架230的另一端与第二主体部221远离第二延伸部222的一端、第二延伸部222与铝挤240的一端、铝挤240的另一端与第一主体部211远离第一延伸部212的一端之间分别通过转动机构200连接。
相比于图3，图4是本发明第二实施例的背板在折叠状态下的俯视图。在从正常使用状态切换到折叠状态时，可取下背板的辅助支架250，并使得第一支架210和第二支架220与第三支架230和铝挤240以转动机构200为轴进行转动，进而使得背板的外框架从矩形结构变为平行四边形结构。背板在折叠状态时，第一主体部211和铝挤240水平连接且位于第一延伸部212和第二延伸部222之间，第二主体部221和第三支架230水平连接且位于第一延伸部212和第二延伸部222之间。进一步地，第一主体部211和铝挤240水平连接时的总长等于第二主体部221和第三支架230水平连接时的总长。
通过上述方式，本实施例的背板同样可在图3所示的正常使用状态与图4所示的折叠状态之间进行切换，且在折叠状态下的占用空间小于在正常使用状态下的占用空间。
在本实施例中，铝挤240临近背光模组的灯条设置，铝挤240既作为背板的一部分起到支撑背板外框架的作用，又可以作为背光模组的散热器件，有利于灯条的散热。
参阅图5，图5是本发明第三实施例的背板在正常使用状态下的俯视图。在本实施例中，背板包括两个第一主拼接件311和313、两个第二主拼接件312和314、四个辅助拼接件321、322、323和324、一个第一辅助机构331、四个第二辅助机构332以及多个转动机构350。
在正常使用状态，第一主拼接件311和313平行设置，第二主拼接件312和314平行设置，进而构成背板的外框架。在本实施例中，第一主拼接件311和313与第二主拼接件312和314的一端通过转动机构350与对应的第二辅助机构332连接，另一端优选通过止位机构360与对应的第二辅助机构332连接。辅助拼接件321、322、323、324交叉设置，且一端通过转动机构350与对应的第二辅助机构332连接，另一端通过转动机构350与第一辅助机构331连接。
其中，止位机构360用以更好的对背板的外框架进行固定。在其他实施例中，为了节省成本以及降低复杂度，可仅在一个或几个连接处设置止位机构360来进行固定。在本实施例中，止位机构360可以由螺钉、铆钉、螺栓等任何适当的固定件实现。
在本实施例中，第二主拼接件312和314至少其中之一者为铝挤，该铝挤临近背光模组的灯条设置，有利于灯条的散热。
参阅图6，图6是本发明第三实施例的背板在折叠状态下的俯视图。在从正常使用状态切换到折叠状态时，背板中的止位机构360被取下，各辅助拼接件321、322、323和324以第一辅助机构331为中心进行转动，缩小背板的宽度，以达到缩小背板的占用空间的目的。同时，第一主拼接件311和313与第二主拼接件312和314以转动机构350为轴，使止位机构360固定的一端向第一辅助机构331处转动。与第一和第二实施例所不同的是，在本实施例中，以第一辅助机构331为中心转动辅助拼接件321、322、323和324，以此来实现在图5所示的正常使用状态与图6所示的折叠状态之间的切换，进而使得背板在折叠状态下的占用空间小于在正常使用状态下的占用空间。
在其他实施例中，可对第三实施例进行简化，例如取消第二辅助机构332。第一主拼接件311和313的一端与第二主拼接件312和314的一端通过转动机构350与对应的辅拼接件321、322、323和324的一端连接。或者，辅拼接件321和323由一个辅拼接件代替，而辅拼接件323和324由另一个辅拼接件代替，并通过转动机构350在二者的中间位置进行连接。
在其他实施例中，本领域技术人员完全可以在不付出创造性劳动的前提下对转动机构的位置以及各种拼接件的设置进行互换或其他变化，只需使得至少部分拼接件之间通过转动机构连接，进而使得背板可在正常使用状态和折叠状态之间进行切换即可实现本发明之目的，并不局限于图1-图6所示的实施例。
图7是本发明背光模组一实施例的结构示意图。如图7所示，背光模组700包括：背板710、导光板720以及灯条730。
其中，导光板720设置于背板710上，且设置于入光侧的背板710为铝挤714，灯条730设置于背板710中的铝挤714朝向导光板720的侧壁上。
在本实施例中，铝挤714不仅是背板710的组成部分，而且作为背光模组700的散热器件，可提高位于导光板720入光侧的灯条730的散热能力，降低灯条730的工作温度，从而提高背光模组700的使用寿命。
图8是本发明液晶显示装置一实施例的结构示意图。如图8所示，液晶显示装置800包括：背光模组700、液晶面板810以及前框820。
其中，液晶面板810设置于背光模组700上，前框820与背板710组装，以使液晶面板810稳固夹持于前框820与背光模组700之间。
本实施例中，由于采用上述实施例的以铝挤作为组成部分以及散热器件的背光模组700，液晶显示装置800的使用寿命显著提高。
综上所述，本发明通过使用铝挤作为拼接式背板的一部分以及散热器件，提高了背光模组的散热性，从而增加了背光模组的使用寿命，并且背板的各拼接件连接处转动连接，使背板可在正常使用状态和折叠状态之间进行切换，并在折叠状态下的占用空间小于在正常使用状态下的占用空间，能够降低背板在运输及仓储过程中的占用空间，提高运输及仓储效率，节约运输成本。
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。
