具体实施方式
下面详细描述本公开的实施例，参考附图描述的实施例是示例性的。下面参考图1-图18描述 根据本公开实施例的车辆1，包括下车身10、后副车架70和电池包20。其中，X方向指的是车辆1的长度方向，也即前后方向；Y方向指的是车辆1的宽度方向，也即左右方向；Z方向指的是车辆1的高度方向，也即上下方向。
具体而言，如图7-图8所示，后副车架70与下车身10连接，电池包20与下车身10连接并设置在下车身10的下侧。后副车架70的前端面701形成为电池包20向后延伸的限位面，也就是说，电池包20可以延伸至后副车架70的前端面701处。
现有技术中的车身地板为乘员舱的承重结构，会与下车身密封连接。而下车身和电池包为单独设计的两个部件，电池包一般设置于车身地板下方并与车身固定连接。因此，电池包在安装时，在车辆的上下方向上与车身结构之间留有一定装配间隙，进而导致电池包与车身地板之间也会形成一定间隙。该间隙在车辆的上下方向上增加了车顶到电池包底部之间的高度，导致车辆的离地间隙降低从而导致车辆的通过性较差，或者导致车辆的车高增高从而导致车辆重心升高，为车辆带来一定的操稳性问题，或者导致车辆的乘员舱高度降低从而影响车辆的用户体验。本申请的车辆1，将电池包20的上壳体和车身地板集成为一体，以电池包的上壳体作为车辆1的地板，省略现有技术中的车身地板的设置，进而减小了车身地板和电池包之间的安装间隙，从而能够有效提高车辆的空间利用率，有效提高车辆的离地间隙，增加乘员舱高度，改善乘客体验，防止重心提高。同时，电池包20可以传力，车辆1的后面发生碰撞时，电池包20可以作为传力结构传导后碰力。车辆1的后部发生碰撞时，后副车架70受到作用力后，会向前与电池包20的后端面201接触，使得电池包20参与传力并将力向前传导。因此，电池包20可以起到抵御和分散传力的作用，以提高车辆1的安全性能。
根据本公开实施例的车辆1，通过将电池包20与下车身10连接，使得电池包20的至少部分上表面可以作为车身地板，以提高车辆1的空间利用率，扩大电池包20的安装空间从而增大电池包20的容量，提高车辆1的空间利用率，降低整车高度，且提高车辆1的通过性能。通过将后副车架70的前端面701形成为电池包20向后延伸的限位面，使得电池包20的安装空间能够向后延伸，进而能够有效地提高电池包20的容量，同时使得电池包20与后副车架70之间的间距减小，且使得电池包20和后副车架70在前后方向上的投影至少部分重合，进而使得电池包20可以作为车辆1的传力结构。当车辆1的后部受到碰撞时，后副车架70可以将碰撞力传递至电池包20，进而提高车辆1的安全性。
在一些实施例中，如图6所示，电池包20的后端面201与后副车架70的前端面701之间的最小距离为L，其中，L满足：10mm≤L≤100mm。如此设置，可以在保证电池包20的安装间隙的同时，有效地增大电池包20的安装空间，使得电池包20的后端面201可以向后扩展，提高电池包20的容量。而且，如此设置，可以使得车辆1的后部受到碰撞时，后副车架70与电池包20接触，使得后碰力可以通过电池包20向前传导，提高了车辆1的安全性。此外，可以避免电池包20的后端面201与后副车架70的前表面发生干涉。另外，在安装电池包20时，后副车架70的前端面701与电池包20不会直接相连并具有一定间隔，便于电池包20的安装，从而提高了车辆1的组装速度。
在一些实施例中，如图1和图3所示，下车身10还包括在车身宽度方向上相对设置的第一门槛梁18及第二门槛梁18’。电池包20与第一门槛梁18和第二门槛梁18’连接以使第一门槛梁18和第二门槛梁18’形成为电池包安装梁。
现有技术中，在车身地板的下侧设置有独立于门槛梁的电池包安装梁，该电池包安装梁设置在车辆的两个门槛梁之间，以使得电池包能够通过该电池包安装梁安装在两个门槛梁之间。然而，这种设计限制了电池包在车辆宽度方向上的延伸，极大地减小了电池包的容量，而且电池包也无法有 效地融入车辆的传力路径。
本申请的车辆1的电池包20的主体的左侧表面可以延伸至第一门槛梁18的右侧，电池包20的主体的右侧表面可以延伸至第二门槛梁18’的左侧。如此，通过将电池包20在Y方向上向两侧延伸，且电池包安装部与第一门槛梁18和第二门槛梁18’相连，提高了电池包20的容纳空间，从而提高了电池包20的容量。同时，由于车辆的门槛梁(第一门槛梁18和第二门槛梁18’)形成为电池包安装梁，且电池包20和车辆门槛梁(第一门槛梁18和第二门槛梁18’)固定连接，在门槛梁进行传力时，电池包20能够有效地参与传力，从而在增加车辆1的传力路径的同时，还能够利用电池包20的大体积和大面积的优势，减小力传递过程中单位面积的受力，减低损坏且提高车辆1的安全性能。简言之，通过上述设置，可以增大电池包20在Y方向的尺寸，提高电池包20的电量，同时提高车辆1的续航能力。此外，当车辆1受到碰撞时，电池包20可以参与传力，提高了车辆1的安全性能。
在一些实施例中，如图1和图2所示，下车身10包括在车身宽度方向上相对设置的第一门槛梁18和第二门槛梁18’。例如，第一门槛梁18位于车身宽度方向上的左侧，第二门槛梁18’位于车身宽度方向上的右侧，其中，电池包20的后端面201在车辆1的长度方向上超出第一门槛梁18的后端面和第二门槛梁18’的后端面。如此设置，能够有效地提高电池包20的长度，使得车辆1在长度方向上有足够的电池包安装空间，从而能够有效提高电池包20的容量。同时，电池包20可以尽量靠近后副车架70，便于电池包20参与传力，提高车辆1的安全性。当然，在另一些实施例中，电池包20的后端面201在车辆1的长度方向上也可以与第一门槛梁18的后端面和第二门槛梁18’的后端面相平齐，在此不做限制。
在一些实施例中，如图6和图7所示，下车身10包括在车身宽度方向上间隔设置的两个后纵梁17，后纵梁17的前段的底面在车辆高度方向上的高度高于电池包20的顶面在车辆1的高度方向上的高度。需要说明的是，这里的“高度”指的是位置关系，并不是尺寸关系。后纵梁17的前段的底面在车辆1的Z方向上位于电池包20的上表面的上方，这里，上方可以为斜上方或者正上方，在此不做限定。如此设置，可以避免后纵梁17的前端对电池包20的安装以及向后延伸造成阻碍，便于电池包20设置于下车身10的下侧，从而能够有效提高车辆1在前后方向上的电池包安装空间，进而提高电池包20的容量，从而提高了车辆1的装配速度，易于实现车辆1的高速生产。
在一些实施例中，如图1和图6所示，车辆1还包括前副车架30，前副车架30与下车身10连接。其中，前副车架30的后端面形成为电池包20向前延伸的限位面。如此设置，电池包20可以延伸至前副车架30的后端面处，增大了电池包20的前后方向的延伸尺寸。同时，电池包20可以延伸至前副车架30，从而在车辆1的前侧发生碰撞时，电池包20可以同时作为传力结构进行传力。
例如，前副车架30的后端面形成为电池包20向前延伸的限位面。在车辆1正常行驶时，前副车架30的后端面与电池包20的前端面间隔设置；在车辆1的正面发生碰撞时，前副车架30受到向后作用力后，会与电池包20的前端面接触，使得电池包20可以参与传力，因此，电池包20可以起到抵御和分散传力的作用，以提高车辆1的安全性能。换言之，如此设置，一方面，可以增大电池包20的X方向的尺寸，提高空间利用率，增加电池包20的容量；另一方面，电池包20可以对前碰力起到分散的作用，以提高车辆1的安全性能。
在一些实施例中，如图2所示，电池包20的前端面与前副车架30的后端面之间至少设置有安装间隙。如此设置，可以防止电池包20的前端面与前副车架30的后端面之间的距离过大，从而增大电池包20在X方向的延伸空间，扩大电池包20的容纳空间，同时可以便于前副车架30与电池 包20接触进行传力，且能够有效防止电池包20在安装时和车辆1发生干涉。
在一些实施例中，如图4和图5所示，下车身10还包括前横梁16以及相对设置的A柱14，前横梁16设置在两个A柱14之间，且前横梁16的左右两端分别和两个A柱14连接。当车辆1发生碰撞时，前横梁16可以将来自车辆1的前碰力分散传递至两个A柱14，或者将侧碰力从一个A柱14传递至另一个A柱14，从而有效增加车辆1的传力路径，减小碰撞对车辆1的破坏，进而提高车辆1的安全性。在一些实施例中，如图2、图4和图5所示，下车身10还包括两个前纵梁50，前纵梁50的后段与前横梁16连接，以能够将来自于车辆1前侧的碰撞力通过前纵梁50传递至前横梁16，进而通过前横梁16传递至A柱14以及与前横梁16连接的中央通道40，从而能够使来自前侧的碰撞力通过前横梁16有效地分散，形成多个传力路径，进而减小车辆1受到碰撞力的损害，从而加强车辆1的结构稳定性，提高了车辆1的安全性能。
在一些实施例中，如图2和图4所示，下车身10还包括前纵梁50，前纵梁50的后端底面与电池包20的顶面在竖直方向上间隔设置以形成密封间隙。前纵梁50的后端底面与电池包20的顶面间隔设置以使得密封结构易于设置于前纵梁50与电池包20之间。同时，由于前纵梁50与电池包20间隔设置，因此在电池包20向前纵梁50方向延伸时前，纵梁50不会对电池包20形成阻碍，从而前纵梁50不会与电池包20发生干涉，避免电池包20的安装受到阻碍，从而能够有效增大车辆1在前后方向上的电池包安装空间，进而提高电池包20容量且便于电池包20的安装。
在一些实施例中，参考图3并结合图4，前纵梁50连接至门槛梁和中央通道40。该门槛梁包括第一门槛梁18和第二门槛梁18’，其中，第一门槛梁18位于车辆1的左侧，第二门槛梁18’位于车辆1的右侧，中央通道400可以位于车辆1的第一门槛梁18和第二门槛梁18’之间。如此设置，在车辆1受到碰撞时，作用力可以通过前纵梁50向第一门槛梁18、第二门槛梁18’以及中央通道40传递，从而能够有效地形成多条传力路径，提高车辆1的传力能力。
在一些实施例中，参考图3-图4并结合图6-图7，下车身10还包括后横梁11以及间隔设置的两个后纵梁17。后横梁11沿车辆1的宽度方向延伸且与后纵梁17以及门槛梁(具体地，第一门槛梁18和第二门槛梁18’)连接，即后横梁11的两端分别与第一门槛梁18和第二门槛梁18’连接，同时后横梁11与后纵梁17的前段连接。其中，后横梁11的下表面的高度高于电池包20的上表面的高度，后纵梁17的前段设置在后横梁11的远离电池包20的一侧。如此设置，可以避免阻碍电池包20延伸以及扩大电池包20的安装空间，且还可以使得在车辆1受到碰撞力时，后纵梁17受到的力都可以传递到后横梁11上，进而通过后横梁11传递到门槛梁上，从而增加传力路径，提高传力效率。
后横梁11还被配置为电池包安装梁，即后横梁11和电池包20固定连接。因而，后横梁11受到的力可以通过连接件传递到电池包20上，从而将电池包20纳入传力路径。另外，基于电池包20的大面积特性，可以有效增强传力效果。可以理解的是，后纵梁17传递到后横梁11的力，一方面可以通过后横梁11传递到两侧的第一门槛梁18和第二门槛梁18’，另一方面还能够通过后横梁11传递到电池包20，从而形成了多条传力路径。而且，通过电池包20增大了传力结构的面积，这能够有效地降低车辆1的碰撞损坏。
在一些实施例中，如图7所示，后横梁11形成为电池包安装梁。电池包20的后端可以通过连接件与后横梁11连接。电池包20的上表面还可以和后横梁11的下表面在竖直方向上间隔设置，从而形成密封间隙。当电池包20和后横梁11连接时，电池包20和后横梁11之间还可以设置密封件6001以形成密封，从而有效避免外物进入乘员舱。电池包20安装于后横梁11上，可以扩展电池包20的长度方向上的容纳空间，从而增加电池包20的容量，提高车辆1的续航能力。
在一些实施例中，如图7和图8所示，后横梁11包括后横梁左连接板112、后横梁右连接板112’以及后横梁本体111。后横梁左连接板112、后横梁本体111以及后横梁右连接板112’依次连接。后横梁左连接板112可以和后横梁本体111的左端的至少部分表面相适配，后横梁右连接板112’可以和后横梁本体111的右端的至少部分表面相适配。如此设置，后横梁左连接板112和后横梁右连接板112’可以提高后横梁11和后纵梁17的连接可靠性，提高了车辆1的安全性。

在一些实施例中，如图7和图8所示，后横梁左连接板112设置在左后纵梁1701的前段，后横梁右连接板112’设置在右后纵梁1701’的前段。后横梁左连接板112与后横梁本体111的左端和第一门槛梁18均连接，后横梁右连接板112’与后横梁本体111的右端和第二门槛梁18’均连接。
如此设置，后横梁左连接板112和后横梁右连接板112’可以使得车辆1的后端在受到碰撞时，后碰力可以从车辆1后端通过后纵梁17向前传导，传至后横梁左连接板112和后横梁右连接板112’及后横梁本体111引导碰撞力向车辆1的宽度方向传导，并通过后横梁左连接板112和后横梁右连接板112’与第一门槛梁18和第二门槛梁18’的连接处引导碰撞力向第一门槛梁18及第二门槛梁18’传导，这可以分散车辆1在后侧受到碰撞时受到的力，从而缓解后碰力，提高了车辆1的承力能力及安全性。
在一些实施例中，如图7和图8所示，后横梁左连接板112设置有第一凸台1121，后横梁右连接板112’设置有第二凸台1121’。其中，第一凸台1121和第二凸台1121’上均设置有后副车架安装点P，且第一凸台1121和第二凸台1121’设置在后横梁本体111沿车辆1长度方向的后侧。第一凸台1121及第二凸台1121’可以在车辆1的长度方向凸出于后横梁本体111，且凸出部分的在宽度方向的截面面积可以逐渐减小。
在本公开的一些实施例中，后横梁11的下方具有用于与后副车架70安装的后副车架安装点P，后横梁11与后副车架70通过螺栓在后副车架安装点P处安装固定。后副车架安装点P处扣设有传力结构，以使后纵梁17、电池包20形成传力区Q，这可以保证后部传力的有效性，提高了车辆1的安全性。
后横梁左连接板112设置有第一凸台1121，后横梁右连接板112’设置有第二凸台1121’，其中，第一凸台1121和第二凸台1121’上均设置有后副车架安装点P，且第一凸台1121和第二凸台1121’设置在后横梁本体111沿车辆1长度方向的后侧。
在一些实施例中，如图7和图8所示，第一凸台1121的下端面和第二凸台1121’的下端面在车辆1高度方向的高度高于后横梁11的下端面的高度。需要说明的是，这里的“高度”指的是位置关系，并不是尺寸关系。如此设置，第一凸台1121和第二凸台1121’可以避免后副车架70与后纵梁17发生干涉，同时提高了第一凸台1121和第二凸台1121’的结构强度，提高了第一凸台 1121和第二凸台1121’与后纵梁17的连接可靠性，提高了传力区Q的承力能力，保证了后部传力的有效性，提高了车辆1的安全性。

此外，车辆1的左侧或右侧受到碰撞时，后座椅前横梁12可以参与传力，由此可以缓解侧碰力的作用效果，避免集中力的作用造成车辆1的损坏，可以提高辆1的安全性。
在一些实施例中，如图7所示，后座椅前横梁12的下表面在车辆1的高度方向的高度高于电池包20的上表面的高度。需要说明的是，这里的“高度”指的是位置关系，并不是尺寸关系。后座椅前横梁12的下表面在Z方向的高度高于电池包20的上表面的高度，由此可以避免后座椅前横梁12的设置对电池包20在Z方向的延伸造成阻碍，从而增大电池包20的Z方向的尺寸，提高空间利用率，提高了车辆1的续航能力。

在车辆1的Y方向上，电池包上壳体2011的左右两侧的安装部分别与第一门槛梁18和第二门槛梁18’固定连接，以使得电池包20能够安装在车身10上。即，电池包上壳体2011的左延伸部20111和第一门槛梁18固定连接，电池包上壳体2011的右延伸部20111’和第二门槛梁18’固定连接。左延伸部和右延伸部上可分别设置多个通孔，两个门槛梁18和18’的对应位置设置有多个通孔，可以通过螺栓19或者螺钉穿过这些通孔以和安装孔固定连接，以使得电池包20和门槛梁18和18’能够有效地固定连接。可选的，左延伸部和右延伸部上的多个通孔沿车辆1的长度方向间隔设置，以使得电池包20能够和车辆1更好地连接。
