由于本示例性实施例中的发电区为平板形状，因此柔性光伏薄膜组件能够直接铺设在发电区上，这样铺设完成以后，柔性薄膜组件不发生应变，基本不会产生应力，因此，在一定程度上减小了安装难度，也能够显著提高安装的牢固程度，延长使用寿命。
第六示例性实施例
如图7-9所示，本示例性实施提供了一种光伏发电车顶，该光伏发电车顶包括结构层和安装在结构层上的柔性光伏薄膜组件1。结构层的中部设置有沉槽(或凹槽)，该沉槽的底面4为单曲面形状；该单曲面的母线为左右延伸的直线段；该母线沿一根在前后方向上延伸的底面4轨迹曲线段移动而形成该单曲面。该沉槽的周围为过渡区，过渡区包括在沉槽的前后两端的第二过渡区2和在沉槽左右两侧的第一过渡区3；第二过渡区2为单曲面形，第二过渡区2的母线为平行于沉槽底面4母线的直线段，该直线段沿一根在前后方向上延伸的第二过渡区2轨迹曲线段移动而形成该单曲面。第一过渡区3为单曲面板，该单曲面板的母线为直线段，该直线沿一根在前后方向上延伸的第一过渡区3轨迹曲线段移动而形成该单曲面板，第一过渡区3轨迹曲线段对应沉槽的部分与底面4轨迹曲线段平行，第一过渡区3轨迹曲线段对应第二过渡区2的部分与第二过渡区2轨迹曲线段平行。
过渡区与沉槽的边缘连接方式包括但不限于采用焊接、粘接、铆接、螺栓连接等方式，当然，还可以采用冲压等方式将沉槽与过渡区进行一体成型。
如图7-9所示，柔性光伏薄膜组件1安装在沉槽内，柔性光伏薄膜组件1通过焊接、粘接、铆接或者螺栓固定、压条压紧等方式固定。
为了将柔性光伏薄膜组件1的接线盒安装在柔性光伏薄膜组件1的下表面，在沉槽的底面4开设通孔，接线盒安装在该通孔内，这样，能够保证柔性光伏薄膜组件1的表面的平整。当然，还可以在沉槽底面4冲压一个小的沉槽，将接线盒安装在小沉槽内，这样，也能够保证柔性光伏薄膜组件1的表面的平整。
柔性光伏薄膜组件1的边缘与沉槽底面4密封连接，这样，能够避 免雨水等污染物进入沉槽底面4与柔性光伏薄膜组件1之间。另外，为了避免由于结构层与柔性光伏薄膜组件1由于温度引起的涨缩率不同而造成应力变化，在柔性光伏薄膜组件1与沉槽边缘之间留出10mm的空隙。为了避免该空隙存留污物，将采用密封材料对该空隙进行填充。
在本示例性实施例的光伏发电车顶中，在结构层中部制作一个沉槽，然后将柔性光伏薄膜组件1直接安装在沉槽内，这样，既不需要众多的零部件，也不需要繁琐的工序，并且其安装过程很快，能够大幅度的降低时间和经济成本。
需要说明的是，在第一示例性实施例至第五示例性实施例中，如图1-6所示，光伏发电车顶的发电区的上表面高于过渡区的上表面，而在第六示例性实施例至第十示例性实施例中，如图7-12所示，光伏发电车顶的发电区的上表面低于过渡区的上表面。换言之，在第六示例性实施例至第十示例性实施例中，第一示例性实施例至第五示例性实施例中的发电区对应于设置在结构层中部的凹槽的凹槽底面，并且柔性光伏薄膜组件的上表面与过渡区的上表面平滑过渡。
第七示例性实施例
如图10-12所示，本示例性实施例提供一种光伏发电车顶，该光伏发电车顶包括结构层，结构层的中部设置有沉槽，该沉槽的底面4为单曲面形状；该单曲面的母线为左右延伸的直线段；该母线沿一根在前后方向上延伸的底面4轨迹曲线段移动而形成该单曲面。该沉槽的周围为过渡区，过渡区包括在沉槽的前后两端的第一过渡区3和在沉槽左右两侧的第二过渡区2；第一过渡区3为单曲面形，第一过渡区3的母线为平行于沉槽底面4母线的直线段，该直线段沿一根在前后方向上延伸的第一过渡区3轨迹曲线段移动而形成该单曲面。第二过渡区2为双曲面形，该双曲面的母线为左右方向延伸的曲线段，该曲线段沿一根在前后 方向上延伸的第二过渡区2轨迹曲线段移动而形成该双曲面，第二过渡区2轨迹曲线段对应沉槽的部分与底面4轨迹曲线段平行，第二过渡区2轨迹曲线段对应第一过渡区3的部分与第一过渡区3轨迹曲线段平行。
具体而言，在本示例性实施例中，沉槽底面为单曲面形，两个第一过渡区分别对应沉槽底面的两个直线边缘设置，两个第二过渡区分别对应沉槽底面的两个弧形边缘设置。第一过渡区具有单曲面形状，第一过渡区的母线与沉槽底面的母线平行。第二过渡区具有双曲面形状，第二过渡区的一个侧面的上边缘与沉槽底面的弧形边缘平行。
过渡区与沉槽的边缘连接方式包括但不限于采用焊接、粘接、铆接、螺栓连接等方式，当然，还可以采用冲压等方式将沉槽与过渡区进行一体成型。
如图10-12所示，柔性光伏薄膜组件1安装在沉槽内，柔性光伏薄膜组件1通过焊接、粘接、铆接或者螺栓固定、压条压紧等方式固定。
为了将柔性光伏薄膜组件1的接线盒安装在柔性光伏薄膜组件1的下表面，在沉槽的底面4开设通孔，接线盒安装在该通孔内，这样，能够保证柔性光伏薄膜组件1的表面的平整。当然，还可以在沉槽底面4冲压一个小的沉槽，将接线盒安装在小沉槽内，这样，也能够保证柔性光伏薄膜组件1的表面的平整。
柔性光伏薄膜组件1的边缘与沉槽底面4密封连接，这样，能够避免雨水等污染物进入沉槽底面4与柔性光伏薄膜组件1之间。另外，为了避免由于结构层与柔性光伏薄膜组件1由于温度引起的涨缩率不同而造成应力变化，在柔性光伏薄膜组件1与沉槽边缘之间留出10mm的空隙。为了避免该空隙存留污物，采用密封材料对该空隙进行填充。
在本示例性实施例的光伏发电车顶中，在结构层中部制作一个沉槽， 然后将柔性光伏薄膜组件1直接安装在沉槽内，这样，既不需要众多的零部件，也不需要繁琐的工序，并且其安装过程很快，能够大幅度的降低时间和经济成本。
第八示例性实施例
本示例性实施例提供一种光伏发电车顶，本示例性实施例与第六示例性实施例的不同之处在于：本示例性实施例的沉槽底面为单曲面形，但该单曲面的母线沿前后方向延伸，而底面轨迹曲线的延伸方向为左右方向。在本示例性实施例中，沉槽前后两端的第二过渡区为单曲面形，第二过渡区的母线与底面的母线平行；沉槽左右两侧的第一过渡区为单曲面形，第一过渡区的母线与底面的母线平行。第一过渡区与第二过渡区的连接部位平滑过渡。当然，也可以将第二过渡区加工成双曲面形，该双曲面顶端处的切线与沉槽底面的母线平行。
第九示例性实施例
本实施例一种光伏发电车顶，其包括结构层，结构层中部设置有沉槽，该沉槽的底面为平板形，在该沉槽的周围为过渡区，过渡区包括在沉槽前后两端的第二过渡区和在沉槽左右两侧的第一过渡区；其中，第一过渡区和第二过渡区均为单曲面形，在前端的第二过渡区的母线平行于沉槽底面的前侧边缘，同样的，在后端的第二过渡区的母线平行于沉槽底面的后侧边缘，在左侧的第一过渡区的母线平行于沉槽底面的左侧边缘，在右侧的第一过渡区的母线平行于沉槽底面的右侧边缘。
在沉槽内安装有柔性光伏薄膜组件，光伏薄膜组件通过焊接、粘接、铆接或者螺栓固定、压条压紧等方式固定。
为了将柔性光伏薄膜组件的接线盒安装在柔性光伏薄膜组件的下表面，在沉槽的底面开设通孔，接线盒安装在该通孔内，这样，能够保证 柔性光伏薄膜组件的表面的平整。当然，还可以在沉槽底面冲压一个小的沉槽，将接线盒安装在小沉槽内，这样，也能够保证柔性光伏薄膜组件的表面的平整。
柔性光伏薄膜组件的边缘与沉槽底面密封连接，这样，能够避免雨水等污染物进入沉槽底面与柔性光伏薄膜组件之间。另外，为了避免由于结构层与柔性光伏薄膜组件由于温度引起的涨缩率不同而造成应力变化，在柔性光伏薄膜组件与沉槽边缘之间留出10mm的空隙。为了避免该空隙存留污物，采用密封材料对该空隙进行填充。
在本示例性实施例的光伏发电车顶中，在结构层中部制作一个沉槽，然后将柔性光伏薄膜组件直接安装在沉槽内，这样，既不需要众多的零部件，也不需要繁琐的工序，并且其安装过程很快，能够大幅度的降低时间和经济成本。
由于本示例性实施例的沉槽底面是平板形的，因此，当柔性光伏薄膜组件铺设在其上时，基本不会产生应力，这有利于延长柔性光伏薄膜组件的使用寿命。
第十示例性实施例
本示例性实施例提供一种光伏发电车顶，其包括结构层，该结构层的中部是通槽，该通槽的底面为单曲面形状；该通槽的左右两侧与过渡区连接，过渡区的形状为单曲面形，该单曲面的母线与通槽底面的母线平行；过渡区和通槽的前后两端都与车体连接，过渡区的外边缘与车体连接，柔性光伏薄膜组件安装在通槽内。在通槽的底面上设置沉槽或通孔，将柔性光伏薄膜组件的接线盒安装在通孔内。同样的，本实施例中的通槽与过渡区可以采用焊接、粘接、铆接、螺栓连接等方式进行连接，也可以采用冲压、铸造等方式一体成型。本实施例中的柔性光伏薄膜组件也可以采用焊接、粘接、铆接、螺栓连接、压条压紧等方式进行固定。
本示例性实施例中还可以将通槽底面的母线沿前后方向安装，此时，过渡区则会位于车体的前侧和后侧。
本实施例中还可以将过渡区加工成双曲面形，双曲面的母线顶端处的切线与通槽底面的母线平行，双曲面的轨迹线与通槽底面的轨迹线平行。
本实施例中，通槽底面还可以为平板形，当通槽底面为平板形时，过渡区只能为单曲面，而不能为双曲面，当过渡区在通槽左侧时，过渡区的母线与通槽底面的左侧平行，同理，当过渡区在通槽前、后、右侧时，过渡区的母线与通槽底面的前、后、右侧平行。
以上实施方式仅为本公开的较佳实施例，但本公开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公开揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应该以权利要求所界定的保护范围为准。
