下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参见图1和图2，如图所示，该台车10包括车主体11、若干承载台12、第一放置区13、第二放置区14及车轮15。具体地，该车主体11包括第一支撑板111、及垂直所述第一支撑板111并固定设置在所述第一支撑板111上表面的第二支撑板112；若干承载台12垂直所述第二支撑板112并对称布设在所述第二支撑板112的两侧，且位于所述第二支撑板112同侧的承载台12呈一列等间距设置，以使显示面板20的一端抵接所述承载台12，另一端抵接所述第二支撑板112斜靠放置；第一放置区13和第二放置区14均位于最下方的承载台12与所述第一支撑板111之间；电源供应器30，放置于所述第一放置区13，并用于为显示面板提供测试电源；信号产生器40，放置于所述第二放置区14，并用于为显示面板提供测试信号源；车轮15，设置于所述第一支撑板111的下表面。
其中，第二支撑板112单侧可以设置多个承载台12，如两个承载台12或三个承载台12，承载台12的具体数量此处不作具体限定。为了使显示面板20斜靠在台车10上，在本申请实施例中，当第二支撑板112单侧设置了多个承载台12之后，相邻的承载台12之间呈等间距设置。在实际应用中，相邻承载台12之间的间距以能够兼容最大尺寸例如60英寸的显示面板为准，从而使相应的显示面板能够借助承载台12斜靠在第二支撑板112上。
其中，第一放置区13和第二放置区14均形成于最下方的承载台12与第一支撑板111之间，且第一放置区13用于放置电源供应器30，第二放置区14用于放置信号产生器40。其中，电源供应器30用于为显示面板20提供测试电源，信号产生器40用于为显示面板20提供测试信号源。如在一些其他实施例中，在第二支撑板112的两侧对称设置有垂直该第二支撑板112的第一隔板16和第二隔板17，该第一隔板16和第二隔板17设置在最底层的承载台12与第一支撑板111之间，且第一放置区13位于第一支撑板111和第一隔板16之间，第二放置区14位于第一支撑板111和第二隔板17之间，且第一隔板16和第二隔板17均与最底层的承载台12之间形成预设间隙。藉由该预设间隙的设置，可以为电源供应器30和信号产生器40的连接线材设置放置空间，防止连接线材的散乱放置。在实际应用中，可以根据电源供应器30和信号产生器40的体积大小来设置第一放置区13和第二放置区14的具体位置。如可以将第一放置区13和第二放置区14对称设置在第二支撑板112的两侧，即将电源供应器30和信号产生器40间隔放置在第二支撑板112的两侧，或者将第一放置区13和第二放置区14设置在第二支撑板112的单侧，即电源供应器30和信号产生器40相邻设置在第二支撑板112的同侧，此处不作具体限定。藉由将电源供应器30和信号产生器40同时放置在台车10上，从而实现不间断地为显示面板20提供老化测试条件，以使显示面板20时刻处于测试状态，从而便于随时随地观察显示面板20的老化异常。
本申请实施例中的台车10通过在第二支撑板112的两侧对称布设若干承载台12，且位于第二支撑板112同侧的承载台12呈一列等间距设置，以使显示面板20能够借助承载台12依靠在第二支撑板112上。由于台车10的两侧可同时置放显示面板20，从而提升了显示面板20的收容数量。此外，该台车10上还设置有电源供应器30及信号产生器40，通过将电源供应器30和信号产生器40放置在台车10上，以实现显示面板20时刻处于测试状态，从而实现随时随地观察显示面板20的老化异常。
进一步地，所述第二支撑板112的每一侧设置有两个承载台12。
具体地，在本申请实施例中，在第二支撑板112的每一侧设置两个承载台12，每一个承载台12可以收纳至少一个显示面板20，如60英寸的显示面板。
进一步地，所述每个承载台12可布设两个显示面板20，且两个所述显示面板20之间无重叠。
具体地，在本申请实施例中，每个承载台12上可布设两个例如60英寸的显示面板20，且两个显示面板20之间无重叠。当本申请实施例中的台车10的第二支撑板112的每一侧设置有两个承载台12，且每一承载台12能够布设两个60英寸显示面板20时，该台车10一共可收纳8片60英寸的显示面板20。可以理解地，将不同尺寸如21.5英寸至60英寸之间的显示面板无重叠的放置在台车10后，该台车10实际收纳的数量将大于等于8片。因此，该台车10可实现收纳至少8片显示面板20，即藉由该台车10单次可收纳至少8片显示面板20。
进一步地，每一所述承载台12远离所述第二支撑板112的边缘位置处均设置有防止所述显示面板20滑落的防滑结构。
为了防止显示面板20从承载台12上滑落，在本申请实施例中，在每一承载台12远离第二支撑板112的边缘位置处均设置有防止显示面板20滑落的防滑结构，进而防止显示面板20滑落，减少破片损失。
进一步地，所述防滑结构为折弯边18，且所述折弯边18所在的平面与所述承载台12所在的平面之间呈钝角。
具体地，在本申请实施例中，该防滑结构为一折弯边18，该折弯边18所在的平面与承载台12所在的平面之间呈钝角。藉由该折弯边18的设置，当显示面板20放置在台车10上之后，可以使显示面板20的一端抵接在折弯边18与承载台12的交界处，其另一端与第二支撑板112相抵接并依靠在第二支撑板112上，从而使显示面板20安全的放置在该台车10上。
进一步地，所述折弯边18与所述承载台12一体成型。
具体地，在本申请实施例中，该折弯边18与承载台12一体成型，从而减少折弯边18额外的制造工序及安装操作。可以理解地，该折弯边18可以全部覆盖承载台12远离第二支撑板112的边缘位置，即覆盖承载台12远离第二支撑板112的整条边；当然该折弯边18还可以是间隔设置在承载台12远离第二支撑板112一端的边缘位置上，此处不作具体限定。
进一步地，所述防滑结构为若干间隔设置在所述承载台12远离第二支撑板112的边缘位置上的优力胶块。
具体地，在其他一些实施例中，该防滑结构为间隔设置在承载台12远离第二支撑板112的边缘位置处的多个优力胶块（图中未示出）。该优力胶块可通过粘贴固定在承载台12上。藉由优力胶块的设置，当显示面板20放置在台车10后，该显示面板20的一端抵接该优力胶，另一端抵接第二支撑板112并依靠在第二支撑板112上，从而防止显示面板20的滑落，进而减少破片损失。同时，优力胶块具有一点的柔软性，当显示面板20与优力胶块接触时，可以防止显示面板20表面被刮伤，进而保护显示面板20的产品质量。
参见图3和图4所示，如图所示，该一种老化测试设备50包括如上所述的台车10，用于承载显示面板20；炉体51，炉体51内形成有收纳台车10的容腔；门体52，活动设置在炉体51上，当将放置有显示面板的台车10置于炉体51的容腔内后，门体52匹配盖合炉体51以便进行老化测试。
在某些实施例中，显示面板20可以为如扭曲向列型面板、平面转换屏幕、多象限垂直配向面板、LCD面板、OLED面板、QLED面板、及曲面显示面板等。
参见图5所示，如图所示，该一种老化测试系统60包括如上所述的老化测试设备50；控制单元（图中未标注），与老化测试设备50电连接，以控制老化测试设备50进行老化测试。
具体地，老化测试设备50包括多个相邻设置的炉体51，为了实现显示面板20的老化测试需要，控制单元包括第一控制单元61和第二控制单元62，且第一控制单元61和第二控制单元62分别设置于炉体51的两侧，第一控制单元61与与之临近的一部分炉体51进行电连接，以控制与之临近一部分炉体51的老化测试；第二控制单元62与剩余的另一部分炉体51进行电连接，以控制剩余的另一部分炉体51的老化测试。在一些实施例中，老化测试设备50可包括4个相邻设置的炉体51，且第一控制单元61与与之临近的两个炉体51进行电连接并控制与之临近的两个炉体51的老化测试，第二控制单元62剩余的两个炉体51进行电连接，并控制剩余的两个炉体51的老化测试。
需要说明的是，为了满足不同的老化测试温度需要，每个炉体51均可以通过对应的控制单元实现独立控制。由于通过每一个炉体51的独立温控已经是本领域技术人员掌握的公知，此处不再赘述。
在本申请实施例中，如上所述的每个台车10至少可以收纳8片显示面板20，而该老化测试设备50的炉体51形成有收纳台车10的的容腔，在进行老化测试时，将放置有显示面板20的台车10置于炉体51的容腔内，并将门体52盖合炉体51并通过对应的控制单元进行老化测试。由于台车10的两侧可同时置放显示面板20，从而提升了显示面板20的收容数量，进而提高了该老化测试设备50单次老化显示面板20的数量，从而提高了老化效率。此外，由于台车10上还设置有电源供应器30及放置信号产生器40，当要观测老化异常时，将台车10从炉体51内移出，并通过台车10上的电源供应器30和信号产生器40使显示面板20保持测试状态，从而当台车10移出炉体51后，即可便捷的观察显示面板20的老化异常。
需要说明的是，在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详细描述的部分，可以参见其他实施例的相关描述。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
