本申请实施例提供的汽车地板，包括：沿车身的车头至车尾依次连接的前地板10和后地板20，以及连接组件。其中，后地板20包括由固定模具制成的第一区域21，以及可变模具制成的第二区域22。连接组件设在后地板20的第二区域22，用于将电池包固定在汽车地板上。不同尺寸的汽车的轴距和电池包的尺寸均不同，这使得电池包固定在汽车地板上的位置也不同，从而导致不同汽车的后地板20不同。本申请的汽车地板中，将汽车地板的可变区域集中在后地板20的第二区域22中，这样在制作后地板20的过程中，只需要根据实际情况更换制作第二区域22的模具即可，制作前地板10和后地板20的第一区域21的模具均可采用统一的模具，基于此，制造不同的汽车时，可以只变更制作后地板20的第二区域22的模具即可，节约了制作模具的时间，进而节约了制作汽车地板的时间，使得汽车地板的开发速度与汽车软件的更新速度相匹配，大大缩短整个汽车的开发周期。
需要说明的是，可变模具的可变可以体现在模具中的镶块的位置可变。
在一实施例中，上述连接组件可以包括第一连接组件和第二连接组件。第一连接组件和第二连接组件间隔的设在后地板20的第二区域22上，且第一连接组件和第二连接组件均与电池包连接。
图3示出了本申请实施例提供的后地板20的第二区域22的局部结构M的示意图。
在一实施例中，如图3所示，上述后地板20的第二区域22上具有第一安装点221A（或221C）和第二安装点222B（或222D）。第一安装点221A（或221C）和第二安装点222B（或222D）的位置可以由电池包的尺寸，以及车身的轴距确定。第一连接组件与第一安装点221A（或221C）连接，第二连接组件与第二安装点222B（或222D）连接。
在实际应用过程中，当电池包的尺寸或者车身轴距发生变化，导致电池包的安装点发生变化时，仅需要重新设计制作后地板的第二区域22的模具中的镶块即可。也就是说，不同的模具中的镶块可以根据计划灵活切换，从而达到模具共用的目的，以节省制作成本。
在一实施例中，如图3所示，上述第一安装点和上述第二安装点均可以为安装立柱。
图4示出了本申请实施例中安装点的位置变化范围的结构示意图。
在一实施例中，如图4所示，第一安装点、第二安装点的位置可以在车身的长度方向变化。具体的，第一安装点221A、第二安装点222B为电池包尺寸最小时的安装点的位置。第一安装点221C、第二安装点222D为电池包尺寸最大时的安装点的位置。第一安装点的位置的变化范围为221A~221C，第二安装点的位置的变化范围为222B~222D。
在一实施例中，如图3和图4所示，上述第一连接组件可以包括：多个第一加强筋31和多个第二加强筋32。其中，第一加强筋31的第一端与第一安装点连接，一个第二加强筋32连接相邻的两个第一加强筋31的第二端。上述第二连接组件可以包括：多个第三加强筋41和多个第四加强筋42。其中，第三加强筋41的第一端与第二安装点连接，一个第四加强筋42连接相邻的两个第三加强筋41的第二端。
如图3和图4所示，为了保证每个安装点的稳定性，多个第二加强筋32和多个第四加强筋42形成不规则的四边形区域。该四边形区域可以由第一边界E、第二边界F、第三边界G和第四边界H组成。其中，第二边界F、第三边界G、第四边界H为硬边界，其由结构限定；第一边界E为软边界，其由材料属性及铸造工艺共同确定。多个第一加强筋31均以第一安装点为中心，与多个第二加强筋32形成多个稳固的三角形，同理，多个第三加强筋41均以第二安装点为中心，与多个第四加强筋42形成多个稳固的三角形。在实际应用中，可以根据实际需要增加三角形的密度。同时，为了满足轻量化的设计需求，三角形的数量也不可过多。也就是说，加强筋的数量须得适量，使得得到的三角形的形状适量，既保证稳定性，也可以满足轻量化的设计需求。
图5示出了本申请实施例提供的汽车地板的结构示意图之二，图6示出了本申请实施例提供的延伸板的结构示意图之一，图7示出了本申请实施例提供的延伸板的结构示意图之二。
在一实施例中，如图5所示，本申请实施例提供的前地板10可以包括前地板本体11和前地板延伸体12。前地板延伸体12的第一端与前地板本体11连接，前地板延伸体12的第二端与后地板20的第二区域22连接，前地板延伸体12的第一端至第二端的长度可以由车身的轴距确定。
为了尽可能的减小由于车身的轴距变化而调整前地板10的更改程度，本申请实施例将前地板10分为了前地板本体11和前地板延伸体12。其中，前地板本体11是由固定模具制作的，其可以适用于多种车型，而前地板延伸体12的长度可随具体车型的车身轴距的变化而变化。也就是说，在生产过程中，可以仅调整前地板延伸体12即可。
具体的，如图6所示，在设计前地板延伸体12的模具时，可以按照车身的最长轴距（即前地板延伸体12的最大长度）设计。不同轴距的切刀通过模具上的机构实现灵活切换，从而得到不同长度的前地板延伸体12，进而实现前地板延伸体12的模具的共用。如图7所示，图7中的前地板延伸体为最小长度的前地板延伸体12，其中，边界P为固定边界，边界O为可变边界。
在实际应用过程中，可以通过改变后地板20的第二区域22的安装点的位置，和/或前地板延伸体12的长度，得到适合不同汽车的汽车地板。在此过程中，只需调整部分模具即可，最大程度上实现模具共用的目的。
在一实施例中，本申请实施例提供的汽车地板的材质对应的比强度大于预设值。该预设值的具体数值可以根据实际情况确定，本申请实施例对此不作具体限制。
示例性的，上述汽车地板的材质可以为铝合金或钢板。
本申请另一实施例中，还提供了一种白车身，该白车身包括上述汽车地板。
与现有技术相比，本申请实施例提供的白车身的有益效果与上述汽车地板的有益效果相同，此处不做赘述。
本申请另一实施例中，还提供了一种汽车，该汽车包括上述白车身。
与现有技术相比，本申请实施例提供的汽车的有益效果与上述汽车地板的有益效果相同，此处不做赘述。
以上所述仅是本申请的一些实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本申请的保护范围。
