光伏组件的边框用于将电池片、玻璃等组成的层压件封装保护起来，使得光伏组件的强度可靠性得到有效提高，延长光伏组件的使用寿命，便于光伏组件的运输和安装。现有技术中，光伏组件通常采用铝合金边框作为最终的封装边框材料，且光伏组件封装之后采用压块将光伏组件安装在支架上。
由于光伏组件材料的价格上升，如现有技术中的光伏组件边框所采用的铝合金材料，以及特定安装区域(如屋顶)对轻质光伏组件的要求等原因，需要不断优化光伏组件设计，在保证光伏组件的可靠性，如机械载荷性能的条件下，控制光伏组件成本，降低光伏组件重量。
因此，光伏组件领域出现了分段式边框组件。分段式边框组件，即设置于层压件四周的边框为间断式设置。
对于分段式边框组件，光伏组件的层压件的四周大部分裸露在外，无支撑物支撑，不仅导致光伏组件的机械载荷性能较低。而且，在将光伏组件安装在支架上并对光伏组件进行接地操作时，一般采取将多段边框分别与地面连接的方式，使得光伏组件的安装较为复杂，极大的增大了光伏组件的安装成本。
为了解决上述现有技术中的问题，如图1至图8所示，本实用新型实施例提供一种光伏组件，包括层压件3和包边框1，包边框1包括一对长边框11和一对短边框12，长边框11具有第一包边槽111，长边框11通过第一包边槽111包覆于层压件3的长边上的外周边沿。短边框12具有第二包边槽121，短边框12通过第二包边槽121包覆于层压件3的短边上的外周边沿，长边框11和相邻的短边框12之间电性连接。
采用上述技术方案的情况下，本实用新型实施例提供的光伏组件包括包边框1，包边框1包括长边框11和短边框12，长边框11包覆于光伏组件的层压件3的长边上的外周边沿，短边框12包覆于层压件3的短边上的外周边沿，使得层压件3的外周具有一层安全保护屏障，提高光伏组件的安全系数，提升光伏组件的机械载荷性能。长边框11和相邻的短边框12之间电性连接，在安装光伏组件的过程中，对光伏组件进行接地操作时，直接将光伏组件的长边框11或短边框12与地面连接即可，便于接地操作，安装操作便捷，降 低光伏组件的安装成本。
需要说明的是，层压件3的长边和短边是相对而言的，层压件3一般为长方形结构，长方形的相对的两个长边的长度大于长方形的相对的两个短边的长度。如图2和图7所示，长边框11的截面形状为C形结构，长边框11具有第一包边槽111，第一包边槽111的结构可以为C形槽结构，第一包边槽111与层压件3的外周边沿相配合，利于长边框11包覆层压件3的外周，便于安装。同样的，如图2和图8所示，短边框12的截面形状为C形结构，短边框12具有第二包边槽121，第二包边槽121的结构可以为C形槽结构，第二包边槽121与层压件3的外周边沿相配合，利于短边框12包覆层压件3的外周，便于安装操作，同时，使得包边框1能够较好的对层压件3进行支撑和保护。
实际情况下，长边框11和短边框12的结构相同。以长边框11为例，长边框11可以由板状材料一体弯折成形，使得长边框11的截面形状为C形结构。当然，长边框11也可以由多块板状材料焊接而成。如图7所示，长边框11包括上板112、下板114和侧边板113，侧边板113相对的两个长边分别与上板112和下板114连接，上板112、下板114和侧边板113围成第一包边槽111，在长边框11的第一包边槽111包覆于层压件3的外周边沿时，侧边板113位于层压件3的外周侧壁，上板112和下板114分别位于层压件3的正面和背面的边沿，使得长边框11包覆于层压件3的外周边沿，用于保护支撑层压件3。
具体实施时，长边框11和相邻的短边框12之间可以具有间隙。如此，不仅节省了包边框1的材料使用，降低了光伏组件的重量，而且便于光伏组件正面的水从间隙内流出。另外，长边框11和相邻的短边框12之间也可以具有搭接区域，即长边框11和相邻的短边框12在层压件3的背面的正投影有部分重合，直接使得长边框11和相邻的短边框12之间电性连接，对光伏组件进行接地操作时，只需将光伏组件的长边框11或短边框12与地面连接即可，便于光伏组件的接地操作，使光伏组件的安装成本降低。不仅如此，长边框11和相邻的短边框12之间具有搭接区域，增强了包边框1的结构的整体性，加强了包边框1对于层压件3的支撑和保护作用，提高光伏组件的安全系数，提升光伏组件的机械载荷性能。
图3和图4示意出本实用新型实施例提供的长边框11与相邻的短边框12之间具有间隙的位置关系示意图。如图3所示，长边框11沿层压件3的长边的延伸方向延伸至层压件3的短边上，短边框12沿层压件3的短边的延伸方向的端面与长边框11之间具有间隙。如图4所示，短边框12沿层压件3的短边的延伸方向延伸至层压件3的长边上，长边框11沿层压件3的长边的延伸方向的端面与短边框12之间具有间隙。具体实施时，当长边框11与相邻的短边框12之间具有间隙时，具体是采用如图3所示的长边框11与相邻的短边框12之间具有间隙的位置关系，或是采用如图4所示的长边框11与相邻的短边框12之间具有间隙的位置关系，此处不作具体限定，根据实际情况进行选择设置。
图5和图6示意出本实用新型实施例提供的长边框11与相邻的短边框12之间具有搭接区域的位置关系示意图。如图5所示，长边框11沿层压件3的长边的延伸方向延伸至层压件3的短边上，短边框12沿层压件3的短边的延伸方向延伸至层压件3的长边上，以对层压件3进行较好的保护和支撑作用。且在搭接区域上，短边框12搭接在长边框11外。即在搭接区域上，长边框11位于短边框12靠近层压件3的一侧。这种情况下，位于层压件3的拐角位置处，短边框12的搭接段朝向远离层压件3表面的一侧凸出，以形成避让长边框11的搭接空间。如图6所示，长边框11沿层压件3的长边的延伸方向延伸至层压件3的短边上，短边框12沿层压件3的短边的延伸方向延伸至层压件3的长边上，且在搭接区域上，长边框11搭接在短边框12外。即在搭接区域上，长边框11位于短边框12远离层压件3的一侧。这种情况下，位于层压件3的拐角位置处，长边框11的搭接段朝向远离层压件3表面的一侧凸出，以形成避让短边框12的搭接空间。具体实施时，当长边框11与相邻的短边框12之间具有搭接区域时，具体是采用如图5所示的长边框11与相邻的短边框12之间具有搭接区域的位置关系，或是采用如图6所示的长边框11与相邻的短边框12之间具有搭接区域的位置关系，此处不作具体限定，根据实际情况进行选择设置。
现将本实用新型实施例提供的位于层压件3的一个拐角处的正面和背面的长边框11与相邻的短边框12之间的位置关系进行组合，列出以下光伏组件的四种实施例，当然，此处只是举例说明，不作具体限定。
实施例1，在层压件3的正面，长边框11和相邻的短边框12之间具有间隙。在层压件3的背面，长边框11和相邻的短边框12之间具有搭接区域。
实施例2，在层压件3的正面和层压件3的背面，相邻的长边框11和短边框12之间均具有间隙。此种情况下，本实用新型实施例提供的光伏组件还包括电连接件，长边框11通过电连接件与相邻的短边框12电性连接。如此，节省了包边框1的材料使用，降低了光伏组件的重量，而且便于光伏组件正面的水从间隙内流出。长边框11通过电连接件与相邻的短边框12电性连接，便于光伏组件的接地操作，使光伏组件的安装成本降低。具体实施时，电连接件可以为导线，导线的两端分别与长边框11和相邻的短边框12连接。
实施例3，在层压件3的正面和层压件3的背面，相邻的长边框11和短边框12之间均具有搭接区域。
实施例4，在层压件3的背面，长边框11和相邻的短边框12之间具有间隙。在层压件3的正面，长边框11和相邻的短边框12之间具有搭接区域。
需要说明的是，实际情况下，层压件3具有四个拐角，四个拐角处的正面和背面的长边框11与相邻的短边框12之间的位置关系可以任意组合，根据实际情况进行设置。
作为一种可能的实现方式，间隙的范围为0mm～10mm，以保证包边框对于层压件的保护支撑作用。示例性的，间隙可以为0mm、1mm、3mm、5mm、6.5mm、8mm、10mm等，此处不作具体限定。需要说明的是，当间隙为0mm时，即长边框与相邻的短边框之间相互接触，以确保长边框与短边框电连接。
在一些实施例中，包边框为钢边框。如此，钢边框强度较高，能够有效保护层压件的外周，加强包边框对于层压件的保护支撑作用，进一步地，提升光伏组件的安全系数。不仅如此，包边框采用钢材质相较于传统边框采用的铝材质，价位较低，有助于降低光伏组件成本。而且，钢材质的包边框具有导电性，便于安装光伏组件时对光伏组件进行接地操作。
在一种可能的实现方式中，参见图1和图2所示，本实用新型实施例提供的光伏组件还包括多组支撑边框2，间隔地设置于长边框11的外部。支撑边框2不仅能够支撑保护长边框11，而且安装时还能够利用支撑边框2与外部的支架连接，通过支撑边框2将光伏组件与外部的支架安装固定，避免通过包边框1直接支撑，降低了包边框1发生弯曲变形的概率，提升了包边框1 对于层压件3的保护支撑作用，进一步提升光伏组件的安全系数。而多组支撑边框2间隔地设置于长边框11的外部，相对于长边框11的外部设置连续的支撑边框2而言，能够减少材料使用，节约光伏组件的成本。
具体安装时，光伏组件通过支撑边框2与支架连接。支架用于支撑光伏组件，使光伏组件设置于支架上，使得光伏组件在减少占地的情况下，发挥其发电作用。支撑边框2与支架连接，使得支架对于光伏组件的应力集中在支撑边框2上，避免支架对于层压件3表面的损坏。在将光伏组件进行接地操作时，使用接地线将光伏组件的长边框11或短边框12与地连接即可，以确保光伏组件的安全使用。
具体实施时，参见图2所示，支撑边框2可以包括可拆卸连接的上边框21和下边框22，上边框21和下边框22之间具有用于夹固长边框11的夹固空间，长边框11位于上边框21和下边框22之间形成的夹固空间内。另外，在夹固空间内，支撑边框2与包边框1之间还可以设置橡胶垫4，橡胶垫4夹置于长边框11和支撑边框2之间，能够缓冲长边框11和支撑边框2的震动。其次，橡胶垫4能够增加长边框11和支撑边框2之间的弹性阻尼，增大了长边框11和支撑边框2之间的摩擦力，提升了支撑边框2设置于长边框11外的稳固性，加强了支撑边框2对于长边框11的支撑保护作用。再者，橡胶垫4能够密封长边框11和支撑边框2，减少水汽等渗入。
另外，本实用新型实施例还提供了一种光伏组件用边框，参见图9所示，包括底板51、侧板52和顶板53，顶板53与底板51平行，底板51、侧板52和顶板53围成包边槽，光伏组件用边框5通过包边槽包覆于光伏组件的层压件的外边沿。底板51的至少一端的端部区域向远离顶板53的方向突出，和/或，顶板53的至少一端的端部区域向远离底板51的方向突出。
采用上述技术方案时，光伏组件用边框5通过包边槽包覆于光伏组件的层压件的外边沿，使得层压件的外周具有一层安全保护屏障，提高光伏组件的安全系数，提升光伏组件的机械载荷性能。底板51的至少一端的端部区域向远离顶板53的方向突出，或顶板53的至少一端的端部区域向远离底板51的方向突出，便于在将光伏组件用边框5包覆在层压件的外边沿后，使得包覆在层压件的长边框上的光伏组件用边框5与包覆在层压件的短边框上的光伏组件用边框5，在层压件的拐角处形成搭接区域，利于实现光伏组件用边框 5之间的电性连接，进一步地，便于光伏组件的接地操作，使光伏组件的安装成本降低。
具体实施时，可以将底板51的一端的端部区域54向远离顶板53的方向突出，也可以将底板51的两端的端部区域54向远离顶板53的方向突出。顶板53的一端的端部区域54向远离底板51的方向突出，也可以将顶板53的两端的端部区域54向远离底板51的方向突出，根据实际情况进行设置。图9示意出本实用新型实施例提供的光伏组件用边框5的一种结构的示意图，参见图9所示，底板51的一端的端部区域54向远离顶板53的方向突出，顶板53的同一端的端部区域54向远离底板51的方向突出。
在一种可能的实现方式中，底板的至少一端的端部区域突出于顶板之外，或顶板的至少一端的端部区域突出于底板之外。
采用上述技术方案时，底板的至少一端的端部区域突出于顶板之外，或顶板的至少一端的端部区域突出于底板之外，由此，便于在将边框包覆在层压件的外边沿后，使得包覆在层压件的长边框上的边框与包覆在层压件的短边框上的边框在层压件的拐角处形成间隙，有利于节省边框的材料使用，降低了光伏组件的重量。另外，当间隙位于层压件的正面时，便于光伏组件正面的水从间隙内流出。具体实施时，可以将底板的一端的端部区域突出于顶板之外，也可以将底板的两端的端部区域突出于顶板之外，顶板的一端的端部区域突出于底板之外，顶板的两端的端部区域突出于底板之外，根据实际情况进行设置。
