【具体实施方式】
请参见图2-3，图2是根据本发明第一实施例的平板显示装置的结构示意图，图3是根据本发明第二实施例的平板显示装置的背框的结构示意图。如图2所示，本实施例的平板显示装置20包括：背光系统21以及显示面板22，背光系统21设置于显示面板22的背面，并且为显示面板22提供光源。
在本实施例中，背光系统21包括光源25、匀光机构24以及背框23。其中，背框23承载光源25和匀光机构24。在背光系统21为侧光式时，匀光机构24是导光板；在背光系统21为直下式时，匀光机构24是扩散板。背框23包括至少第一主拼接件和第二主拼接件，至少第一、第二两个主拼接件形成背框23的主框架27。
一起参阅图3，背框23的第一实施例包括第一主拼接件261以及第二主拼接件262。第一主拼接件261的一端与第二主拼接件262的一端拼接，第一主拼接件261的另一端与第二主拼接件262的另一端拼接，以形成背框23的主框架27。第一主拼接件261和第二主拼接件262均为铝件或镀锌钢件。在本实施例中，第一主拼接件261和第二主拼接件262为L形。
一起参阅图4，背框23的第三实施例包括第一主拼接件281、第二主拼接件282以及第三主拼接件283。三个主拼接件281、282以及283拼接形成背框23的主框架27。三个主拼接件281、282以及283均为铝件或镀锌钢件。第一主拼接件281的一端与第二主拼接件282的一端拼接，第二主拼接件282的另一端与第三主拼接件283的一端拼接，第三主拼接件283的另一端与第一主拼接件281的另一端拼接。
在本实施例中，第一主拼接件281为L形，第二、三主拼接件282、283均为直条形。
此外，背框23还可以包括设置于主框架27内并与之拼接的辅拼接件。
以下以四个主拼接件和两个辅拼接件详细说明本发明平板显示装置20的背框23。
请参见图5，图5根据本发明第四实施例的平板显示装置的背框的结构示意图。如图5所示，在本实施例中背框23包括：第一主拼接件231、第二主拼接件232、第三主拼接件233、第四主拼接件234、第一辅拼接件235、第二辅拼接件236以及支架2371、2372、2373、2374、2375、2376及2377。第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234通过首尾拼接形成背框23的主框架27。第一辅拼接件235和第二辅拼接件236作为辅拼接件，设置于主框架27内，并且与主框架27拼接。
具体而言，第一主拼接件231的一端与第二主拼接件232的一端拼接，第二主拼接件232的另一端与第三主拼接件233的一端拼接，第三主拼接件233的另一端与第四主拼接件234的一端拼接，第四主拼接件234的另一端与第一主拼接件231的另一端拼接，以形成长方形的主框架27。其中，第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234均为铝件或镀锌钢件。在本实施例中，第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234均为直条形，在其他实施例中，本领域技术人员完全可以将第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234全部设置为L形，或部分设置为直条形，剩余的设置为L形。例如，在图3中，第一主拼接件261和第二主拼接件262全部设置为L形；在图4中，第一主拼接件281设置为L形，第二、三主拼接件282以及283设置为直条形。
请参见图6，图6是根据本发明第五实施例的平板显示装置中的两个主拼接件拼接处的截面示意图。在本实施例中，平板显示装置20的背框23均采用拼接连接方式进行拼接固定。如图6所示，以第一主拼接件231的一端与第二主拼接件232的一端拼接连接方式为例，将第二主拼接件232的一端拼接在第一主拼接件231的一端上，比如，采用螺接、扣接或焊接等方式将第二主拼接件232的一端拼接在第一主拼接件231的一端上。
请参见图7，图7是根据本发明第六实施例的平板显示装置中的第一辅拼接件对角设置在主框架上的示意图。在本实施例中，第一辅拼接件235和第二辅拼接件236设置于背框23的主框架27内。第一辅拼接件235的一端与第一主拼接件231拼接，第一辅拼接件235的另一端与第三主拼接件233拼接，第二辅拼接件236的一端与第一主拼接件231拼接，第二辅拼接件236的另一端与第三主拼接件233拼接，并且第二主拼接件232、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236之间平行设置。在其它实施例中，本领域技术人员在主框架27内设置至少一个辅拼接件，例如在主框架27内仅仅设置第一辅拼接件235。此外，第一辅拼接件235的两端可以分别与第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234中的至少两个主拼接件拼接，例如第一辅拼接件235对角设置在主框架27内，如图7所示。同理可知，第二辅拼接件236的两端亦可以分别与第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234中的至少两个主拼接件拼接。
请参见图8，图8是根据本发明第七实施例的平板显示装置中的第一辅拼接件以及第二辅拼接件在主框架上的示意图。例如，第一辅拼接件235的两端分别与相邻设置的第一主拼接件231、第二主拼接件232拼接，第二辅拼接件236的两端分别与相邻设置的第三主拼接件233、第四主拼接件234拼接。
在本实施例中，背框23包括七个支架2371、2372、2373、2374、2375、2376及2377。其中，支架2371固定于第四主拼接件234上，支架2372、2373分别固定于第一辅拼接件235上，支架2374固定在第二辅拼接件236上，支架2375固定在第二主拼接件232上，支架2376、2377的两端分别固定于第一辅拼接件235和第二辅拼接件236上。实际上，支架可以固定于第一主拼接件231、第二主拼接件232、第三主拼接件233、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236之一或以上。在其他实施例中，本领域技术人员完全可以在背框23上设置其他数量的支架，比如一个支架或以上。此外，支架可以拆卸固定于第一主拼接件231、第二主拼接件232、第三主拼接件233、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236之一或以上。
在支架2371、2372、2373、2374、2375、2376及2377上均设有凸包（未标示），背框23可以通过该凸包固定电路板等器件。
以下进一步说明上述背框23相应的模具。在本实施例中，第一主拼接件231和第三主拼接件233的尺寸相同，形状相同，使用相同的模具冲压制得。第二主拼接件232、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236的尺寸相同，形状相同，使用相同的模具冲压制得，实现模具共用。因此，本发明的背框23可以通过使用两种小尺寸模具冲压制得，相比于现有技术中背框10需要大尺寸模具，本发明的背框23的模具结构简单且小，进而降低背框23模具的成本。此外，本发明的背框23相对于现有技术中背框10的整体背框，能够大幅节省材料，以降低平板显示装置20的生产成本。
请参见图9，图9是根据本发明第八实施例的一种平板显示装置的背框中拼接部的结构示意图。如图9所示，在本实施例中，第一主拼接件的一端设有两个拼接部，拼接部的结构与相应的第二主拼接部的一端适配，以使第一主拼接件与相应的第二主拼接件的一端拼接。
具体而言，第一主拼接件231的一端表面至少设有拼接部2311、2312，拼接部2311、2312沿第一主拼接件231的长度方向上间隔排列，拼接部2311、2312是在第一主拼接件231设置的形状与第二主拼接件232的一端适配的凹部，以收容第二主拼接件232的一端。
参见图10，图10是图9中拼接部的第一实施例的截面示意图。如图10所示，拼接部2311、2312为未贯穿第一主拼接件231的一端相对两侧面的凹部，凹部的形状为矩形，第二主拼接件232为一直条形。
在拼装较大尺寸背框23时，首先选择较邻近第一主拼接件231的端部的拼接部2311，并选择相应宽度的第二主拼接件232。随后将第二主拼接件232的一端设置在拼接部2311的凹部上。随后通过螺接、扣接或焊接等方式将第二主拼接件232的一端拼接固定在拼接部2311上。在拼装较小尺寸背框23时，首先选择较远离第一主拼接件231的端部的拼接部2312，并选择相应宽度的第二主拼接件232。随后将第二主拼接件232的一端设置在拼接部2312的凹部上。随后通过螺接、扣接或焊接等方式将第二主拼接件232的一端拼接固定在拼接部2312上。
请参见图11，图11是根据本发明第九实施例的一种平板显示装置的背框中拼接部的拼接方式的示意图。如图11所示，为方便另一方向上背框23尺寸的可选，例如在第二主拼接件232的表面相应位置设有凸起，其中第二主拼接件232的凸起嵌入第一主拼接件231相对应位置的凹部，以拼接第一主拼接件231和第二主拼接件232。此外，所述第二主拼接件232的一端表面可以设有至少两个沿第二主拼接件232长度方向上间隔排列的凸起，比如两个、三个或四个等。
更进一步，如图12所示，图12是根据本发明第十实施例的一种平板显示装置的背框中拼接部的拼接方式的示意。第一主拼接件231的凹部为多阶梯结构的凹部，第二主拼接件232相对应位置设有与凹部适配的多阶梯结构的凸部，如图12所示。
此外，如图13所示，图13是根据本发明第十一实施例的一种平板显示装置的背框中拼接部的拼接方式的示意图。以拼接部2311为例，第一主拼接件231的凹部底部设有第一贯穿孔2313，第二主拼接件232相应于拼接部2311的位置上设有第二贯穿孔2321，背框23进一步包括固定件240，固定件240穿过第一贯穿孔2313和第二贯穿孔2321，以将第一主拼接件231和第二主拼接件232拼接。
如图14，图14是根据本发明第十二实施例的一种平板显示装置的背框中拼接部的结构示意图。在本发明平板显示装置的背框的另一实施例中，第一主拼接件231的拼接部2311、2312的凹部形状为圆形。但是，在其他实施例中，本领域技术人员完全可以将凹部的形状设置成三角形等其他多边形形状。
如图15，图15是根据本发明第十三实施例的一种平板显示装置的背框中利用不同拼接部进行的结构示意图。本实施例中，拼接部2311、2312为贯穿第一主拼接件231的相对两侧的凹部，以使第二主拼接件232的一端在拼接部2311、2312上移动。比如在第二主拼接件232的一端穿出拼接部2312并拼接固定后，可裁切掉穿出部分，进而调节第二主拼接件232在作为背框主拼接件时的长度，从而得到不同尺寸的背框。
在实际应用中，第一主拼接件231的另一端以及第三主拼接件233的两端均设有两个拼接部，其结构与拼接部2311、2312的结构相同；而在第二主拼接件232的两端和第四主拼接件234的两端，对应于不同的情况，也相应进行设计或不设计，比如：
1）第一种情况，如图10所示，第二主拼接件232的两端和第四主拼接件234的两端可以不进行任何设计，即端部与其他部位的结构相同，这时候在选择第一主拼接件231一端的不同拼接部2311（2312）进行拼接时（另一端同样处理），若想背框23的宽度相应变化，则相应的第二主拼接件232和第四主拼接件234的长度也作相应的选择。即，若选邻近第一主拼接件231一端的拼接部2311进行拼接，则不对第二主拼接件232和第四主拼接件234进行裁剪，或裁剪掉的部分较短；若选择较远离第一主拼接件231一端的拼接部2312进行拼接时，则对第二主拼接件232和第四主拼接件234均进行裁剪，按照拼接部距离第一主拼接件231一端的远近，裁剪掉的部分也较长或较短；
2）第二种情况，类似前述第一种情况，如图11所示，只不过第二主拼接件232和第四主拼接件234以不同的凸起来分别与第一主拼接件231和第三主拼接件233配合，实现背框23的宽度变化；同样，若选择除离第一主拼接件231一端最近的第一拼接部2311之外的其他拼接部2312进行拼接时，在拼接后或拼接前，将多出的第二主拼接件232和第四主拼接件234部分进行裁剪。
以上情况也适用于仅用两个L形主拼接件进行拼接而得到背框23的主框架27。
综上所述，本发明的背框23的第一主拼接件上设有至少两个拼接部，根据用户需求进行设置拼接部的数量，在本实施例中选取两个拼接部2311、2312进行描述。因此，在设置背框23的模具时，仅需设置两组模具，即第一主拼接件的模具以及第二主拼接件的模具，在第一主拼接件上设置多个拼接部以拼接得到各种尺寸的背框23。在拼装背框23时，可以根据背框23的尺寸，选择相应的拼接部，通过拼接部将第二主拼接件拼接在第一主拼接件的拼接部上，并将第一主拼接件中位于第二主拼接件的拼接位置外侧的其他拼接部裁切掉，以获取所需尺寸的背框23。相对于现有技术中根据不同尺寸的背框10设置不同背框模具，本发明的平板显示装置的背框23仅需设置第一主拼接件的模具和第二主拼接件28的模具，实现满足各种尺寸产品要求的模具共用，并且模具结构简单，能够降低背框模具的成本。
本发明还提供一种制造平板显示装置的背框的模具，该背框的模具设有用于形成背框的主拼接件的主图案，主图案设有上设有用于在主拼接件的一端形成至少两个拼接部的子图案。其中，主拼接件为上述第一主拼接件和第二主拼接件，对应上述的主图案；拼接部为上述第一主拼接件的拼接部，对应上述的子图案，在此不再赘述。
请参见图16-17，图16是根据本发明第十四实施例的平板显示装置的背框的结构示意图，图17是根据本发明第十五实施例的平板显示装置的结构示意图。下面以四个主拼接件和两个辅拼接件为例，说明本发明平板显示装置20的背框23在主拼接件设置有发热源时，该主拼接件和其它未设置发热源的拼接件在材料选择上的不同。
四个主拼接件和两个辅拼接件中，至少两个主拼接件中包括用于设置发热源的主拼接件，用于设置发热源的主拼接件具有第一导热能力，至少两个主拼接件中其余不用于设置发热源的一个或以上主拼接件具有第二导热能力；其中，第一导热能力大于第二导热能力。
发热源可以为发光二级管（LED）、印制电路板（PCB）或其他发热的电子器件，在此处以LED为例。表征导热能力的参数可以是导热系数，也就是说设置于发热源的主拼接件的导热系数大于其余不用于设置发热源的一个或以上主拼接件的导热系数。
用于设置发热源的主拼接件具有第一强度，至少两个主拼接件中其余不用于设置发热源的一个或以上主拼接件具有第二强度，第二强度大于第一强度。
具有第一导热能力和第一强度的主拼接件是铝件，具有第二导热能力和第二强度的主拼接件是镀锌钢件。当然，除了铝件外，散热能力较高的还可以是铜件、镁合金或开口泡沫铝合金等；而除了镀锌钢件外，强度高的还可以是有机片或马口铁等。
下面再以四个主拼接件和两个辅拼接件组成的背框为例，如图16-17，第一主拼接件291、第二主拼接件292、第三主拼接件293、第四主拼接件294、第一辅拼接件295以及第二辅拼接件296组成背框。其中设置发热源25的主拼接件是第二主拼接件292和第四主拼接件294，第二主拼接件292和第四主拼接件294由铝件M1制作，其它未设置发热源25的第一主拼接件291、第三主拼接件293、第一辅拼接件295以及第二辅拼接件296由镀锌钢件M2制作。
此外，用于设置发热源的主拼接件也可以是层叠的第一层和第二层结构，其中第一层邻近发热源设置，第一层的导热能力大于第二层的导热能力。
第一层邻近发热源设置，第一层的材料可以选择导热能力大于第二层的材料，例如第一层是铝件，或者铜件、镁合金或开口泡沫铝合金等，第二层是镀锌钢件，或者有机片、马口铁等。当然，设置发热源25的主拼接件可以是只有一层，材料用上述第一层的材料制作。
铝件、铜件等具有较好的散热效果，有利于提高产品的寿命；镀锌钢板等散热效果较差，但价格相对便宜，强度较高。背框的成本中，原材料成本占的比重最大。如果背框全部使用铝件等具有较好的散热效果的材料，成本太高，且结构强度较差；全部使用镀锌钢板等散热效果较差的材料，则散热不好，降低产品性能。因此在实际应用中根据需要，不同的位置使用不同的材料制作，比如铝件和镀锌钢板搭配，可以使产品成本最低化，同时保证散热和强度满足需求。减少材料成本，从而降低产品成本。当然，上述拼接件在材料选择上不同的实施例，也同样适用于采用两个L型主拼接件来拼接得到主框架的情况。
本发明还提供一种可应用于上述各实施例所揭示的背框的支架，其中，支架固定于主拼接件或辅拼接件上，或同时固定于主拼接件和辅拼接件上，支架与主拼接件或辅拼接件之间的可选固定点设有至少两个，以使得支架可选地设置于背框的不同位置，从而满足背框的不同装配需求。
请参阅图18，图18是根据本发明第十六实施例的平板显示装置的背框的局部结构示意图。在本实施例中，支架60由支架组件601、602拼接而成，支架60的两端分别固定于拼接件61、62上。拼接件61、62可沿支架60的长度方向固定于支架60的至少两个不同位置，其中，拼接件61、62可以是上述各实施例中的主拼接件或辅拼接件。在其他备选实施例中，支架60可以仅一端固定于拼接件上，另一端悬空设置，且支架60也可以是一体设计。
进一步如图19-20所示，在支架组件601与拼接件61相互固定的端部，在支架组件601上沿支架60的长度方向上设置有条状贯穿孔6011。支架组件601通过螺钉63固定在背框的拼接件61上。螺钉63可以设置于条状贯穿孔6011的不同位置。因此，在安装时，将条状贯穿孔6011与拼接件61的螺孔611重叠，并根据安装需要沿支架60的长度方向调节支架组件601在拼接件61上的位置，进而调节支架组件601的凸包6012相对于拼接件61的位置。在将支架组件601的凸包6012调节到适当位置后，将螺钉63设置到条状贯穿孔6011的相应位置，并锁定到拼接件61的螺孔611中，进而并将支架组件601固定到拼接件61上。
同理，进一步如图21-22所示，在支架组件602的与拼接件62相互固定的端部，沿支架60的长度方向上设置有条状贯穿孔6021，可以设置螺钉64于条状贯穿孔6021的不同位置，并通过将螺钉64锁定到拼接件62的螺孔621内，进而将支架组件602固定于拼接件62上，由此实现凸包6022相对拼接件62的位置调节。
进一步如图23-24所示，在支架组件601与支架组件602相互固定的端部，在支架组件601上沿支架60的长度方向上设置有条状贯穿孔6013，而在支架组件602上沿支架60的长度方向上设置有条状贯穿孔6023。支架组件601通过螺钉65固定于支架组件602。其中，螺钉65可设置于条状贯穿孔6013、6023的不同位置。在安装时，将条状贯穿孔6013、6023重叠，并根据安装需要沿支架60的长度方向调节支架组件601和602的位置，而进调节凸包6012、6022相对于拼接件61、62（见图18）的位置以及支架60的长度。在位置调节后，将螺钉65设置到条状贯穿孔6013和6023的相应位置，并进行锁定，以将支架组件601固定到支架组件602上。在其他备选实施例中，螺钉63、64、65可以由铆钉或螺栓等其他固定件代替。
如图25所示，图25是根据本发明第十七实施例的平板显示装置的背框的局部结构示意图。在本实施例中，在支架上沿支架的长度方向间隔设置有至少两个贯穿孔来取代上述实施例的条状贯穿孔。具体而言，在支架组件701的与拼接件71相互固定的端部，沿支架70的长度方向上设置有多个贯穿孔7014、7015、7016。螺钉（未绘示）可以设置于贯穿孔7014、7015、7016中的一者内，并锁定于拼接件71的螺孔711内，从而将支架组件701固定于拼接件71上，由此实现凸包7012相对拼接件71的位置调节。
同样地，在支架组件702的与拼接件72相互固定的端部，沿支架70的长度方向上设置有多个贯穿孔7024、7025、7026。螺钉（图未示）可以设置于贯穿孔7024、7025、7026中的一者内，并锁定于拼接件72的螺孔721内，从而将支架组件702固定于拼接件72上，由此实现凸包7022相对拼接件72的位置调节。
另外，在支架组件701与支架组件702相互固定的端部，在支架组件701上沿支架70的长度方向上设置有多个贯穿孔7017、7018、7019，而在支架组件702上沿支架70的长度方向上设置有多个贯穿孔7027、7028、7029。螺钉（图未示）可设置于多个贯穿孔7017、7018、7019中的任意一者与多个贯穿孔7027、7028、7029的任意一者内。在安装时，根据安装需要沿支架的长度方向调节支架组件701和702的位置，并将对应的贯穿孔重叠，从而调节凸包7012、7022相对于拼接件71、72的位置以及支架70的长度。在位置调节后，将螺钉设置到对应的贯穿孔重叠位置上，并进行锁定，以将支架组件701固定到支架组件702上。
以上实施方式中，利用螺钉将支架固定于拼接件，但本领域技术人员也可以轻易联想到可用铆钉等固定件进行固定，本发明对此不作具体限定。
此外，本发明还提供一种可应用于上述各实施例所揭示的背框的加强结构，背框的主拼接件数量至少为两个，至少一个主拼接件的一端设有拼接部，至少两个主拼接件通过相应拼接部拼接，至少其中一个主拼接件的拼接部设有加强结构以使背框整体的强度达到要求。
具体而言，请参阅图26，图26是以图3所示的背框为例说明拼接部的加强结构示意图。在本实施例中，第一主拼接件261包括拼接部2611，第二主拼接件262包括拼接部2621，第一主拼接件261与第二主拼接件262中的至少一个在其拼接部设有加强结构（图未示），即至少在拼接部2611或拼接部2621设有加强结构。
下面以拼接部2611与拼接部2621均设有加强结构为例进行说明。
拼接部2611和拼接部2621沿A-A’方向的横截面为折线形状，以形成加强结构，折线形状包括至少两条相连线段，比如加强结构的折线形状是矩形（如图27所示，其中虚线圈内为两加强结构的凹凸叠置结构）、梯形（如图28所示）、燕尾形（如图29所示）、倒T形（如图30所示）、锥形（如图31所示）、波纹形（如图32所示）或网格形（如图33所示），还可以是T形、十字形或叉形等。第一主拼接件261的拼接部2611的加强结构和第二主拼接件262的拼接部2621的加强结构之间凹凸叠置。
或者，拼接部2611和拼接部2621沿A-A’方向的横截面为弧形，以形成加强结构。横截面为弧形时，弧形是一个或以上的单曲率（如图34所示）、双曲率（如图35所示）或多曲率弧形（如图36所示）。第一主拼接件261的拼接部2611的加强结构和第二主拼接件262的拼接部2621的加强结构之间凹凸叠置。
当然形成加强结构沿A-A’方向的横截面的形状不仅限于此，只要能加强拼接部的强度即可。并且，值得注意的是，图27-图37所示主拼接件的拼接部所有实施例中，除图27示出拼接部2611的加强结构和拼接部2621的加强结构的形状以及两加强结构的凹凸叠置结构之外，其余均只示出拼接部2611或拼接部2611其中之一的加强结构的形状而并未示出其凹凸叠置的结构。
参阅图37，其是在拼接部2621设有加强结构的另一结构示意图。该加强结构是板层2623，该板层2623是对拼接部2621的加厚，并且拼接部2611和拼接部2621叠置。
以上可以了解，本发明实施例，通过拼接方式形成背框，使背框的结构简单，并且节省背框的材料，可降低背光显示装置的生产成本；同时，通过在主拼接件的拼接位置设置加强结构，能提高背框拼接处的强度，进而使背框整体的强度达到要求。
值得注意的是，前述加强结构的各个实施例也适用于下述各背框、背光系统或平板显示装置的实施例。
综上所述，本发明提出了另一种平板显示装置的背框。请参阅图38，图38是根据本发明第十八实施例的平板显示装置的背框的结构示意图。图38是本实施例综合了背框拼接、可调节支架、加强结构以及多材料的所有特征的示意图，在本实施例中，第一主拼接件291、第二主拼接件292、第三主拼接件293以及第四主拼接件294（图未示）组成背框的主框架，第一辅拼接件295、第二辅拼接件296与主框架拼接。

支架60固定于第一辅拼接件295、第二辅拼接件296上，其中支架与辅拼接件之间的可选固定点设有至少两个，以使得支架可选地设置于背框的不同位置。支架60为上述各实施例描述的支架之一。在本实施例中，以贯穿孔601和贯穿孔602为例，说明支架可选地设置于背框的不同位置，这里所说的贯穿孔即是可选固定点。支架60可通过贯穿孔601、602沿支架60的长度方向移动以调节位置，当位置调节好后，将固定件如螺钉、铆钉或螺栓等其他固定件设置到贯穿孔601和贯穿孔602的相应位置，并进行锁定，以将支架60固定到背框的另一位置。
另外，第三主拼接件293以及第四主拼接件294（图未示）设置有发热源H，其制作材料为具有第一导热能力的铝件M1，其它没有设置发热源的第一主拼接件291、第二主拼接件292、第一辅拼接件295以及第二辅拼接件296均为具有第二导热能力的镀锌钢件M2。
