详述
除非另有定义，本申请实施例所用的所有技术术语均具有与本领域技术人员通常理解的相同的含义。
在本申请实施例中，所涉及的“上”与“下”、或者“顶”与“底”均以附图1至附图5、附图7至附图8、附图9至附图14、附图16中所示的上与下、或者顶与底的方位为基准。
下面将结合附图对本申请实施方式作进一步地详细描述。
一方面，本申请实施例提供了一种光伏模块单元，如附图1和附图2所示，该光伏模块单元100包括：光伏组件110，还包括透光承重件120和用于支撑光伏组件110和透光承重件120的支撑件130。其中：支撑件130包括第一支撑面138a和第二支撑面138b，第一支撑面138a位于第二支撑面138b上方，透光承重件120设置于第一支撑面138a，光伏组件110设置于第二支撑面138b。
由于第一支撑面138a位于第二支撑面138b上方，透光承重件120和光伏组件110分别设置于第一支撑面138a和第二支撑面138b，所以，透光承重件120位于光伏组件110的正上方，以对光伏组件110起到覆盖和保护作用。
本申请实施例提供的光伏模块单元，通过将支撑件130支撑在基体300(例如支架、地面、建筑物表面)上，以对光伏组件110和透光承重件120进行支撑。通过使透光承重件120和光伏组件110分别设置于支撑件130的第一支撑面138a和第二支撑面138b，并且，第一支撑面138a位于第二支撑面138b上方，使得透光承重件120位于光伏组件110上方，透光承重件120不仅可对光伏组件110进行保护和覆盖，还可承受人或者重物，利于高效利用设置有该光伏模块单元100的地面、建筑物等基体300的表面空间资源。此外，该光伏模块单元100还具有结构简单、安装成本低、维护方便、节约安装时间、节约用地、可安装于不同基体300上等优点。
在本申请实施例中，第一支撑面138a和第二支撑面138b的设置形式有多种。在基于结构简单，容易设置的前提下，给出以下两种示例：
作为第一种示例，如附图2和10所示，支撑件130包括：第一支撑部132a和设置于第一支撑部132a的侧壁的第二支撑部133a，第一支撑面138a设置在第一支撑部132a上，第二支撑面138b设置在第二支撑部133a上。如附图2和10所示，第一支撑部132a的顶面为第一支撑面138a，第二支撑部 133a的顶面为第二支撑面138b。
上述支撑件130的设置方式简单，利于第一支撑部132a和第二支撑部133a分别对透光承重件120和光伏组件110进行支撑。并且，第一支撑部132a的侧壁还能够对光伏组件110的端部起到保护作用。
其中，透光承重件120的每个端部均可以设置于第一支撑部132a上，也可以仅相对的两端设置于第一支撑部132a上。同样地，光伏组件110的每个端部均可以设置于第二支撑部133a上，也可以仅相对的两端设置于第二支撑部133a上。
作为第二种示例：如附图11所示，支撑件130包括：主体部139，主体部139上设有用于卡合透光承重件120的一端的第一卡槽134b和用于支撑光伏组件110的第三支撑部135b。其中第一卡槽134b位于第三支撑部135b的上方，第一卡槽134b的下表面为第一支撑面138a，第三支撑部135b的上表面为第二支撑面138b。
上述支撑件130的设置方式简单，第一卡槽134b和第三支撑部135b不仅能够分别将透光承重件120和光伏组件110固定，第一卡槽134b和主体部139的侧壁还分别对透光承重件120的端部和光伏组件110的端部起到保护作用。
具体地，透光承重件120的端部可以设置为与第一卡槽134b相适配的结构，以牢固、稳定地进行卡合。如图11所示，透光承重件120的端部可设置与第一卡槽134b相适配的凸起，该凸起可插入第一卡槽134b内。
其中，透光承重件120的每个端部均可以卡合于第一卡槽134b内，也可以仅相对的两端卡合于第一卡槽134b内。
作为第三种示例，如附图3和12所示，支撑件130包括：主体部139，主体部139上设有用于卡合透光承重件120的一端的第二卡槽136c和用于卡合光伏组件110的一端的第三卡槽137c。其中第二卡槽136c位于第三卡槽137c的上方，第二卡槽136c的下表面为第一支撑面138a，第三卡槽137c的下表面为第二支撑面138b。
上述支撑件130的设置方式简单，第二卡槽136c和第三卡槽137c不仅能够分别将透光承重件120和光伏组件110固定，还对透光承重件120的端 部和光伏组件110的端部起到保护作用。
透光承重件120的端部和光伏组件110的端部可以分别设置为与第二卡槽136c和第三卡槽137c相适配的结构，以牢固、稳定地进行卡合。如图12所示，透光承重件120的端部可设置与第二卡槽136c相适配的凸起，该凸起可插入第二卡槽136c内，光伏组件110的端部与第三卡槽137c相适配，并可直接插入第三卡槽137c内。
其中，透光承重件120的每个端部均可以卡合于第二卡槽136c内，也可以仅相对的两端卡合于第二卡槽136c内。同样地，光伏组件110的每个端部均可以卡合于第三卡槽137c内，也可以仅相对的两端卡合于第三卡槽137c内。
针对支撑件130包括第一支撑部132a和第二支撑部133a的情形，第二支撑部133a可以与第一支撑部132a的侧壁垂直连接，也可以不与第一支撑部132a的侧壁垂直连接。考虑到光伏组件110设置于第二支撑部133a上的稳定性，如附图2和10所示，第二支撑部133a可以与第一支撑部132a的侧壁垂直连接。
光伏组件110的底面可以通过多种方式设置于第二支撑部133a的顶面(即第二支撑面138b)上，以下给出几种示例：
作为第一种示例，光伏组件110的底面可通过结构胶粘结在第二支撑部133a的顶面上。
采用结构胶粘结的方式简单，连接力度好。
作为第二种示例，光伏组件110的底面可通过卡接的方式设置在第二支撑部133a的顶面上。
具体地，第二支撑部133a的顶面上可设置有卡接槽，光伏组件110的底面可设置有与卡接槽相适配的卡接件，通过使光伏组件110底面的卡接件卡接于卡接槽内，实现光伏组件110的底面固定在第二支撑部133a的顶面上。当然，也可以在光伏组件110的底面设置卡接槽，在第二支撑部133a的顶面上设置与卡接槽相适配的卡接件。其中，对于卡接槽和卡接件的结构不作具体限定，满足实现卡接即可。
卡接的方式容易设置，方便光伏组件110与支撑件130之间的拆装。
作为第三种示例，光伏组件110的底面通过第一固定件设置于第二支撑部133a的顶面上。其中，第一固定件可以为卡子，通过将卡子卡在光伏组件110的端部和第二支撑部133a上，实现光伏组件110的底面固定于第二支撑部133a的顶面上。
考虑到作用于透光承重件120上的重力不会损坏光伏组件110，第一支撑面138a与第二支撑面138b之间的距离可以大于光伏组件110的厚度。
如此设置，使透光承重件120与光伏组件110之间具有间隙140，参见附图1或者附图2，这避免了透光承重件120上的重力直接作用于光伏组件110上，提高了透光承重件120对光伏组件110的保护能力。
需要说明的是，光伏组件110与透光承重件120之间的间隙140大小能够满足透光承重件120不会对光伏组件110施加重力即可。
考虑到在安装透光承重件120时，能够容易地对透光承重件120进行定位，以方便安装，支撑件130还包括：定位部131，定位部131用于对透光承重件120的端部进行限位。
在一些实施例中，如附图2和10所示，定位部131用于在第一方向上对透光承重件120进行限位，第一方向为：与第一支撑部132a的设有第二支撑部133a的侧壁垂直的方向。
具体地，在附图2所示的实施例中，定位部131包括侧板，该侧板可与透光承重件120的端部抵接，并在与第一支撑部132a的设有第二支撑部133a的侧壁垂直的方向(即水平方向)上对透光承重件120进行限位。
在附图10所示的实施例中，定位部131包括垂直连接的顶板1311和侧板1312，顶板1311的顶面高于侧板1312的顶面。该侧板1312可与透光承重件120的端部抵接，并在与第一支撑部132a的设有第二支撑部133a的侧壁垂直的方向(即水平方向)上对透光承重件120进行限位。
在一些实施例中，如附图3、11和12所示，主体部139的位于第二支撑面138b以上的部分为定位部。其中，第一插槽134b的侧壁和顶壁可对透光承重件120的端部进行限位，或者第二插槽136c的侧壁和顶壁可对透光承重件120的端部进行限位。

考虑到在安装该光伏模块单元100后，使光伏模块单元100的表面平齐，不会产生台阶，进而使基体300表面更平整，以不影响基体300表面的正常使用，可将透光承重件120的端部设置为阶梯结构121。
在一些实施例中，如附图2或者附图5所示，透光承重件120的端部为阶梯结构121，阶梯结构121设有与定位部131的顶面配合的第一面1211和与第一支撑面138a配合的第二面1212。阶梯结构121还包括设置在第一面1211和第二面1212之间的竖直的第三面1213，该第三面1213可与定位部131配合限位。
可以理解的是，第一面1211高于第二面1212，第二面1212为透光承重件120的底面。
如此设置，使得透光承重件120的端部覆盖在定位部131的上端，以使该光伏模块单元100的上表面为平整面，以利于基体300(例如地面)的正常使用。并且，如此设置，还使定位部131对透光承重件120端部的一部分(即第三面1213)起到保护作用。
此外，阶梯结构121包括但不限于第一面1211、第二面1212和第三面1213，其还可以设置为两层以上台阶面，相应地，定位部131的顶面和/或第一支撑部132a的顶面设置为与其相适配的结构。

可以理解的是，第一面1211高于第二面1212，第二面1212为透光承重件120的侧面。
如此设置，可以使定位部131对透光承重件120端部的侧面和顶面进行保护，而且利于使定位部131的顶面与透光承重件120的顶面齐平，以利于基体300(例如地面)的正常使用。
此外，阶梯结构121包括但不限于第一面1211和第二面1212，其还可以设置为多层台阶面，相应地，定位部131设置为与其相适配的结构。

为了保证支撑件130与透光承重件120之间不会出现震动异响，定位部131与透光承重件120之间、以及第一支撑面138a与透光承重件120之间可以固定连接。
在附图2和5所示的实施例中，阶梯结构121的第一面1211可与定位部131的顶面连接，和/或，阶梯结构121的第二面1212可与第一支撑面138a连接。

在附图2和5所示的实施例中，定位部131的顶面与阶梯结构121的第一面1211之间的连接方式有多种，以下给出几种示例：
作为第一种示例，定位部131的顶面可通过结构胶与阶梯结构121的第一面1211粘结连接。
粘结连接的方式简单，连接力度好，并且，粘结层还起到了缓震的作用，利于基体300(例如地面)使用的舒适度。
此外，还可以在定位部131与第三面1213之间设置粘结层，以使定位部131与透光承重件120牢固连接。
为了使定位部131的顶面与阶梯结构121的第一面1211之间具有优异的连接力度，可以在定位部131的顶面和/或阶梯结构121的第一面1211设置粗糙结构。
具体地，粗糙结构可以通过设置圆形、方形、条形等规则或者不规则的条纹来形成。

需要说明的是，销钉穿入沉孔后，其上端与透光承重件120的上端齐平，以保证该光伏模块单元100的表面平齐。
示例地，第二固定件可以为卡子，卡子同时卡在透光承重件120的阶梯结构121和定位部131上，以实现阶梯结构121与定位部131之间的连接。

在一示例性实施例中，防滑防震垫150可以为橡胶垫。
橡胶垫的防滑防震效果好，价格低廉，容易获取。
在本申请实施例中，定位部131、第一支撑部132a、第二支撑部133a可以通过多种形式构成支撑件130，在基于容易生产制造的前提下，给出以下两种示例：
作为第一种示例，定位部131、第一支撑部132a和第二支撑部133a为一体式结构。
如此设置，利于支撑件130的生产制造，避免拆装等繁琐操作。
作为第二种示例，如附图5和14所示，第一支撑部132a和第二支撑部133a为一体式结构，定位部131通过紧固件160固定于第一支撑部132a的第一侧壁，其中：第一支撑部132a的第一侧壁与第一支撑部132a设有第二支撑部133a的侧壁相对设置。
如此设置，可以在透光承重件120放置于第一支撑部132a的顶面上后，再将定位部131固定于第一支撑部132a的第一侧壁，避免因定位部131限位而不能将透光承重件120设置于第一支撑部132a的顶面的情形。
其中，紧固件160可以为螺栓，即定位部131可以通过螺栓与第一支撑部132a固定连接。采用螺栓连接的方式简单，且螺栓容易获取。
具体地，定位部131和第一支撑部132a上可以分别设置有第一螺纹孔和第二螺纹孔，通过使螺栓螺纹穿入第一螺纹孔和第二螺纹孔，实现定位部131和第一支撑部132a之间的固定连接。
在本申请实施例中，考虑到支撑件130的质量轻化特性和机械强度，支撑件130的材质可以为铝合金材质。如附图5和14所示，第一支撑部132a上可以设有镂空结构，例如第一支撑部132a可以为框体结构。
透光承重件120的材质能够满足透光和支撑重物即可.举例来说，透光承重件120的材质可以为玻璃(如钢化玻璃)，还可以为透光的塑料板。
考虑到透光承重件120的机械强度，透光承重件120可以为多层夹胶玻璃。
考虑到透光承重件120的机械强度、成本、以及不影响基体300(例如地面)表面空间资源的正常使用，透光承重件120可以为双层夹胶防滑玻璃。
具体地，透光承重件120的上表面可以设置为带有花纹的粗糙结构，以增加其摩擦系数。
光伏组件110可以设置为多种结构。作为一种示例，光伏组件110包括：叠层设置的透光前板、太阳能电池和背板。其中，太阳能电池可以为太阳能薄膜电池(CuIn xGa (1-x)Se 2，CIGS)，其具有光吸收能力强，发电稳定性好、转化效率高、发电时间长、发电量高、生产成本低及能源回收周期短等优点。
考虑到该光伏组件110不仅具有优异的机械强度，并且占地空间小，该光伏组件110可以为双玻薄膜光伏组件。即，透光前板和背板的材质均为玻璃。
另一方面，本申请实施例还提供了一种光伏装置，如附图6所示，该光伏模块包括多个上述提及的任一种光伏模块单元100，相邻的光伏模块单元100之间设有固定连接件200，光伏模块单元100与固定连接件200连接，参见附图7或15。
多个光伏模块单元100之间的排列方式有多种，能够满足使用要求即可。举例来说，或者，多个光伏模块单元100之间排列成直线，或者，多个光伏模块单元100之间排列成矩形结构，或者，多个光伏模块单元100之间排列成梯形结构。
相邻的光伏模块单元100之间设有固定连接件200，以利于光伏模块单元100之间的固定连接。
其中，固定连接件200可以选为多种，在基于容易获取，方便实现稳定连接的前提下，给出以下示例：

光伏模块单元100与工型支撑部210固定连接时，相邻两个光伏模块单元100的相邻近的端部固定于位于其间的工型支撑部210的顶部。相邻的工型支撑部210之间通过角钢220连接时，该相邻的工型支撑部210之间垂直设置。
工型支撑部210的材质可以选为多种，考虑到支撑效果和成本等因素，工型支撑部210可以为工字型钢。作为一种示例，如附图7或15所示，工字型钢的底端固定在水泥路块上，顶端与支撑件130的底部固定连接。
针对相邻的工字型钢通过角钢220连接的情形，角钢220的相互垂直的两个侧面上分别设置第一连接孔和第二连接孔，工字型钢上设置有第三连接孔，通过使用紧固螺栓230紧固于第一连接孔和工字型钢的第三连接孔内，且使用紧固螺栓230紧固于第二连接孔和相邻工字型钢(该工字型钢与前述工字型钢垂直设置)的第三连接孔内，实现两个工字型钢之间的垂直连接。
在本申请实施例中，每个光伏组件110均与接线盒111电连接，参见附图2和10，以能够为外界机器设备供电。各个光伏组件110之间可以通过接线盒111进行电连接。用于连接各个接线盒111之间的导线可以通过夹线夹固定。
考虑到能够对电连接的接线盒111的导线进行保护和限位，如附图7和15所示，工型支撑部210(例如工字型钢)上设置有过线孔211，各个光伏组件110电连接后的导线可以通过过线孔211引出。此外，在工型支撑部210上设置过线孔211，还可起到使工型支撑部210质量轻化的作用，方便工人施工。
上述提及，光伏模块单元100固定于工型支撑部210的顶部，可以使工型支撑部210的顶面与支撑件130的底面连接。两者连接后，在基体300(例如地面)使用过程中，不可避免地出现滑动或者震动的现象，影响基体300使用的舒适度。为了解决这一问题，如附图8和16所示，固定连接件200的顶面与支撑件130的底面之间设置有第二防滑防震垫151。
具体地，支撑件130可以安装在第二防滑防震垫151上，周边打耐候胶，这不仅增加了支撑件130和第二防滑防震垫151之间的连接力度，还可增加第二防滑防震垫151的耐气候老化性能，延长其使用寿命。
考虑到相邻的光伏模块单元100之间不会发生碰撞磨损，以及基体300(例如地面)的完整性能，相邻的光伏模块单元100可以均固定在上述提及的第二防滑防震垫151的两侧，参见附图8和16。
具体地，第二防滑防震垫151可包括底部和侧部，底部设置在固定连接件200的顶面与支撑件130的底面之间，侧部设置在相邻的光伏模块单元100。在附图7、8、15和16所示的实施例中，第二防滑防震垫151大致呈几字形。第二防滑防震垫151还可以呈其他形状，如倒T字形等。
光伏模块单元100可以与第二防滑防震垫151的侧部的侧面粘结连接。粘结连接的方式简单，连接力度好。
作为一种示例，第二防滑防震垫151的侧部的上表面与透光承重件120的上表面齐平，以利于使基体300(例如地面)的表面平整。
在本申请的描述中，术语“多个”指两个或更多个。
以上所述仅为本申请实施例的说明性实施例，并不用以限制本申请实施例的保护范围，凡在本申请实施例的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请实施例的保护范围之内。
