其中，凸台和滑槽由对应的所述支架冲压形成。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种显示器背板，该显示器背板包括多个支架，其中至少两个支架之间通过连接槽进行铰接，连接槽包括设置于一支架的端部的滑槽以及设置于另一支架的端部的凸台，凸台滑动保持于滑槽内，凸台和滑槽设置成允许至少两个支架绕垂直于显示器背板所在平面的第一转轴进行相对转动。

【附图说明】
图1是本发明显示器背板一实施例在组装状态下的立体示意图；
图2是图1所示的显示器背板在拆分状态下的立体示意图；
图3是图1所示的显示器背板的连接槽的局部示意图；
图4是本发明显示器背板的第一主轴和第二主轴在显示器背板平面的主视图。
【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。
请参照图1至图2，本发明实施例提供一种显示器背板，该显示器背板包括两个第一支架10、两个第二支架20和两连接件40。
在本实施例中，两个第一支架10相互平行，两个第二支架20相互平行，第一支架10和第二支架20按照第一支架10-第二支架20-第一支架10-第二支架20-第一支架10的顺序首尾铰接，形成一个平行四边形框架。
在本实施例中，在平行四边形框架对角设置的两个顶角，第一支架10与第二支架20之间通过连接槽30进行铰接。连接槽30包括滑槽11和凸台21。滑槽11设置在支架10的一端部且滑槽11为圆弧形滑槽，凸台21设置在支架20的一端部且凸台21为圆弧形凸台，凸台21滑动保持于滑槽11内。滑槽11和凸台21优选分别由第一支架10和第二支架20冲压形成。
在平行四边形框架的对角设置的另外两个顶角，第一支架10与第二支架20之间通过连接件40进行铰接。第一支架10设通孔12，第二支架20的对应位置处设通孔22，连接件40穿设于通孔12与通孔22内从而将第一支架10和第二支架20连接起来。其中，通孔12与滑槽11间隔设置，通孔12设置在支架10的另一端部。通孔22与凸台21间隔设置，通孔22设置在支架20的另一端部。
在本实施例中，通过两个连接槽30进行铰接的第一支架10和第二支架20可以绕垂直于显示器背板所在平面的第一转轴（未图示）进行相对转动。通过两个连接件40进行铰接的第一支架10和第二支架20可以绕垂直于显示器背板所在平面的第二转轴（未图示）进行相对转动。
为了保证圆弧形滑槽11和圆弧形凸台21的匹配效果，优选地，圆弧形滑槽11和圆弧形凸台21同心设置，因此第一转轴的转动轴心即滑槽11和凸台21的圆心，且第一转轴与显示器背板所在的平面垂直。
连接件40通过通孔12、22连接第一支架10和第二支架20，因此，通孔12、22同心设置。第二转轴的转动轴心即通孔12和22的圆心，且第二转轴与显示器背板所在的平面垂直。
请一并参见图3，具体来说，圆弧形滑槽11包括间隔设置且中心轴与第一转轴同轴设置的第一圆弧形侧壁110和第二圆弧形侧壁111。圆弧形凸台21包括间隔设置且中心轴与第一转轴同轴设置的第三圆弧形侧壁210和第四圆弧形侧壁211。第三圆弧形侧壁210和第四圆弧形侧壁211滑动保持于第一圆弧形侧壁110和第二圆弧形侧壁111之间。进一步，圆弧形滑槽11包括连接第一圆弧形侧壁110和第二圆弧形侧壁111的第一顶壁112，圆弧形凸台21包括连接第三圆弧形侧壁210和第四圆弧形侧壁211的第二顶壁212，第二顶壁212可相对第一顶壁112滑动。
通过上述方式，由滑槽11和凸台21铰接的第一支架10和第二支架20可绕第一转轴进行转动，且通过连接槽30铰接的铰接位置处机械强度较好。
请一并参照图4，在本实施例中，第一转轴与显示器背板所在平面的两个交点A与第二转轴与显示器背板所在平面的两个交点B之间的连线形成一个平行四边形，因此第一支架10和第二支架20可分别相对第一转轴和第二转轴旋转且旋转后的显示器背板的体积较小，能够较大程度地减小显示器背板在包装运输过程中所占用的包装运输体积，从而减少显示器背板在包装运输过程中的包装运输成本。
在其他实施例中，平行四边形框架中的第一支架10和第二支架20均可通过连接槽30进行铰接，也就是说通过四个连接槽30进行铰接，且第一转轴与显示器所在平面的四个交点A之间的连线形成一平行四边形。通过四个连接槽30进行铰接的平行四边形框架，框架的整体机械强度得到提高，同时可实现第一支架10与第二支架20的四铰接位置处分别相对第一转轴的转动，进而减少显示器背板的体积。
本发明进一步提供一种液晶显示器，包括了上述显示器背板。
本发明的有益效果是：与现有技术相比，本发明显示器背板包括多个支架，其中至少两个支架之间通过连接槽进行铰接且可绕垂直于显示器背板所在平面的第一转轴进行相对转动。转动后支架所形成的显示器背板的体积较小，能够较大程度地减小显示器背板在包装运输过程中所占用的包装运输体积，从而减少显示器背板在包装运输过程中的包装运输成本。
以上所述仅为本发明的实施方式，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。
