下面参考附图描述根据本申请实施例的车辆2。
如图1-图7所示，根据本申请实施例的车辆2包括车身骨架和车身骨架接头1。
所述车身骨架具有横梁30和纵梁40，横梁30和纵梁40相连。横梁30和纵梁40可为铝合金材料制造。
首先参考附图描述根据本申请实施例的车身骨架接头1。
如图2-图6所示，根据本申请实施例的车身骨架接头1包括横梁连接板10和纵梁连接板20。
横梁连接板10上设有第一横梁安装件110和第二横梁安装件120，横梁连接板10通过第一横梁安装件110和第二横梁安装件120安装于横梁30。纵梁连接板20与横梁连接板10相连，纵梁连接板20设有第一纵梁安装件210和第二纵梁安装件220，纵梁连接板20通过第一纵梁安装件210和第二纵梁安装件220安装于纵梁40。
其中，第一横梁安装件110的中心轴线和第一纵梁安装件210的中心轴线位于第一平面内，第二横梁安装件120的中心轴线和第二纵梁安装件220的中心轴线位于第二平面内，所述第一平面和所述第二平面平行设置。
举例而言，车身骨架接头1连接横梁30和纵梁40，呈L型。所述第一平面和所述第二平面沿车辆2的宽度方向间隔分布，且所述第一平面和所述第二平面垂直于所述车身骨架的宽度方向。
根据本申请实施例的车身骨架接头1，在横梁连接板10上设置第一横梁安装件110和第二横梁安装件120，且在纵梁连接板20设置第一纵梁安装件210和第二纵梁安装件220，这样可以利用第一横梁安装件110和第二横梁安装件120将横梁连接板10安装于横梁30，且利用第一纵梁安装件210和第二纵梁安装件220将纵梁连接板20安装于纵梁40，且第一横梁安装件110和第一纵梁安装件210所在的第一平面内，与第二横梁安装件120和第二纵梁安装件220所在的第二平面内，两者间隔且平行设置，这样车身骨架接头1与车身骨架的安装点形成了两个平面内的连接，从而提高了车身骨架接头1的刚度和强度，优化了抗扭性能。
如此，本申请实施例的车身骨架接头1具有连接强度和刚度高、抗扭性能好等优点。
根据本申请的一些具体实施例，如图2-图6所示，横梁连接板10和纵梁连接板20垂直设置且两者的连接处倒圆角。如此，横梁连接板10和纵梁连接板20适于连接在横梁30和纵梁40的直角连接处，且横梁连接板10和纵梁连接板20的过渡平缓，可以减小应力集中。
根据本申请的一些具体实施例，如图2-图3所示，第一横梁安装件110包括第一横钉杆111和铆接于第一横钉杆111的第一横套环112，第二横梁安装件120包括第二横钉杆121和铆接于第二横钉杆121的第二横套环122。第一纵梁安装件210包括第一纵钉杆211和铆接于第一纵钉杆211的第一纵套环212，第二纵梁安装件220包括第二纵钉杆221和铆接于第二纵钉杆221的第二纵套环222。
进一步的，横梁30构造有第一横滑槽310和第二横滑槽320，纵梁40构造有第一纵滑槽410和第二纵滑槽420。横梁30和纵梁40上双滑槽的构造与车身骨架接头1的连接件相配合，提高了车身骨架的刚度、强度和抗扭性能。
横梁连接板10设有第一横钉杆孔113和第二横钉杆孔123，第一横钉杆111穿过第一横钉杆孔113且可滑动地配合于第一横滑槽310，第二横钉杆121穿过第二横钉杆孔123且可滑动地配合于第二横滑槽320。纵梁连接板20设有第一纵钉杆孔213和第二纵钉杆孔223，第一纵钉杆211穿过第一纵钉杆孔213且可滑动地配合于第一纵滑槽410，第二纵钉杆221穿过第二纵钉杆孔223且可滑动地配合于第二纵滑槽420。
其中，第一横钉杆111、第二横钉杆121、第一纵钉杆211和第二纵钉杆221露出第一横套环112、第二横套环122、第一纵套环212和第二纵套环222的部分应该尽可能的小，以减小操作空间和方便车内的内饰设计。第一横滑槽310和第二横滑槽320 沿车辆2的长度方向延伸，沿车辆2的宽度方向间隔分布。第一纵滑槽410和第二纵滑槽420沿车辆2的高度方向延伸，沿车辆2的宽度方向间隔分布。
如此，采用滑槽的方式将车身骨架接头1安装于车身骨架，不仅安装效率高，而且安装时无需钻孔，保证了结构强度，此外，采用铆接代替相关技术中的螺栓连接，能够避免因紧固力矩不到位而松脱的情况，保证了连接的可靠性。根据本申请的一些具体实施例，如图2-图3所示，第一横钉杆111套设有位于第一横钉杆111和横梁连接板10之间的第一横垫片114，第一横垫片114可滑动地配合于第一横滑槽310。第二横钉杆121套设有位于第二横钉杆121和横梁连接板10之间的第二横垫片124，第二横垫片124可滑动地配合于第二横滑槽320。
第一纵钉杆211套设有位于第一纵钉杆211和纵梁连接板20之间的第一纵垫片214，第一纵垫片214可滑动地配合于第一纵滑槽410。第二纵钉杆221套设有位于第二纵钉杆221和纵梁连接板20之间的第二纵垫片224，第二纵垫片224可滑动地配合于第二纵滑槽420。
举例而言，第一横垫片114、第一纵垫片214、第二横垫片124和第二纵垫片224可为金属薄片，例如铝合金薄片，它们可在中心线上开有通孔，用于安装第一横钉杆111、第一纵钉杆211、第二横钉杆121和第二纵钉杆221，它们的尺寸可根据实际情况进行增大或减小。安装完成后，第一横垫片114、第一纵垫片214、第二横垫片124和第二纵垫片224分别与第一横滑槽310、第一纵滑槽410、第二横滑槽320和第二纵滑槽420的槽底贴合。
如此，第一横垫片114、第一纵垫片214、第二横垫片124和第二纵垫片224采用金属薄片，可以有效地减小整车的重量。并且当横梁30和纵梁40受力时，第一横垫片114、第一纵垫片214、第二横垫片124和第二纵垫片224与第一横滑槽310、第一纵滑槽410、第二横滑槽320和第二纵滑槽420的接触面承受载荷作用，可以消减第一横滑槽310、第一纵滑槽410、第二横滑槽320和第二纵滑槽420的应力集中，使车身骨架满足强度和变形的要求。
根据本申请的一些具体实施例，如图2-图6所示，横梁连接板10的内侧表面和纵梁连接板20的内侧表面设有第一内筋50，横梁连接板10上的第一内筋50与纵梁连接板20上的第一内筋50通过第一拐角筋510相连，第一拐角筋510位于横梁连接板10和纵梁连接板20的连接处。横梁连接板10的内侧表面和纵梁连接板20的内侧表面还设有第二内筋60，横梁连接板10上的第二内筋60与纵梁连接板20上的第二内筋60通过第二拐角筋610相连，第二拐角筋610位于横梁连接板10和纵梁连接板20的连接处。其中，所述横梁连接板的内侧表面为横梁连接板朝向所述横梁的表面，所述纵梁连 接板的内侧表面为纵梁连接板朝向所述纵梁的表面。
具体的，第一拐角筋510的厚度大于第一内筋50的厚度，第二拐角筋610的厚度大于第二内筋60的厚度。
举例而言，横梁连接板10上第一内筋50、纵梁连接板20上的第一内筋50和第一拐角筋510可以位于第一平面内；横梁连接板10上的第二内筋60、纵梁连接板20上的第二内筋60和第二拐角筋610可以位于第二平面内。
如此，第一内筋50、第二内筋60、第一拐角筋510和第二拐角筋610的设置，使车身骨架接头1的结构紧凑，结构强度高、连接强度好、耐久度高。
根据本申请的一些具体实施例，如图2-图3所示，第一横钉杆孔111贯通横梁连接板10上的第一内筋50，横梁连接板10上的第一内筋50配合于第一横滑槽310，第一纵钉杆孔211贯通纵梁连接板20上的第一内筋50，纵梁连接板20上的第一内筋50配合于第一纵滑槽410，第一拐角筋510配合于第一横滑槽310和第一纵滑槽410的连接处。第二横钉杆孔121贯通横梁连接板10上的第二内筋60，横梁连接板10上的第二内筋60配合于第二横滑槽320，第二纵钉杆孔221贯通纵梁连接板20上的第二内筋60，纵梁连接板20上的第二内筋60配合于第二纵滑槽420，第二拐角筋610配合于第二横滑槽310和第二纵滑槽420的连接处。
举例而言，第一内筋50的厚度小于第一横滑槽310安装面的壁厚和第一纵滑槽410安装面的壁厚，第二内筋60的厚度小于第二横滑槽320安装面的壁厚和第二纵滑槽420安装面的壁厚，以便于铆接时第一横垫片114、第二横垫片124、第一纵垫片214和第二纵垫片224分别于与第一横滑槽310、第一纵滑槽410、第二横滑槽320和第二纵滑槽420接触，而不是与车身骨架接头1接触，避免铆接松动。第一拐角筋510和第二拐角筋610设置在不影响第一横垫片114、第二横垫片124、第一纵垫片214和第二纵垫片224安装的位置，提高车身骨架接头1的刚度性能。
如此，不仅提高了车身骨架接头1与车身骨架的连接强度，而且保证了车身骨架接头1自身的结构强度。第一拐角筋510插入第一横滑槽310和第一纵滑槽410，第二拐角筋610插入第二横滑槽320和第二纵滑槽420，对车身骨架接头1增加了约束，提高了车身骨架接头1的抗扭性能。第一内筋510插入第一横滑槽310和第一纵滑槽410，第二内筋610插入第二横滑槽320和第二纵滑槽420，使车身骨架接头1和横梁30与纵梁40共同抵抗变形，提高车辆2的整体刚度。
根据本申请的一些具体实施例，如图2-如6所示，横梁连接板10的外侧表面和纵梁连接板20的外侧表面设有位于两者连接处的外筋70，外筋70倒圆角，其中所述横梁连接板的外侧表面为所述横梁连接板远离所述横梁的表面，所述纵梁连接板外侧表面 为所述纵梁连接板远离所述纵梁的表面。
换言之，外筋70连接横梁连接板10和纵梁连接板20，外筋70与横梁连接板10和纵梁连接板20连接的部分倒圆角，如此，连接过渡平缓，圆角半径尽可能大以减小连接位置的应力集中。
进一步的，如图2-如6所示，外筋70为多个且沿横梁连接板10和所述纵梁连接板20的宽度方向间隔设置。举例而言，外筋70为两个，且分别设置在车身骨架接头1的两侧边缘。
如此，提高了车身骨架接头1的结构强度、耐久性能和抗扭性能，减小了车身骨架接头1的拐角位置的应力集中。
根据本申请的一些具体实施例，如图2-如6所示，第一横梁安装件110相对于第二横梁安装件120更加邻近纵梁连接板20，第二纵梁安装件220相对于第一纵梁安装件210更加邻近横梁连接板10。如此，可以将第一横梁安装件110和第二横梁安装件120的位置错开，将第二纵梁安装件220和第一纵梁安装件210的位置错开，通过不同的铆接顺序，不仅可以实现车身骨架接头1尺寸更小，方便车辆2的内饰设计，而且减少了安装操作所需的空间和安装时间。
下面描述车身骨架接头1与车身骨架的连接过程。
首先，将第一横垫片114套入第一横钉杆111，第一纵垫片214套入第一纵钉杆211，第二横垫片123套入第二横钉杆123，第二纵垫片224套入第二纵钉杆221，再将带有垫片的第一横钉杆111和第二横钉杆123分别滑入横梁30的第一横滑槽310和第二横滑槽320，带有垫片的第一纵钉杆221和第二纵钉杆223分别滑入纵梁40的第一纵滑槽410和第二纵滑槽420。
然后，将横梁连接板10套入第一横钉杆111和第二横钉杆孔123，纵梁连接板20套入第二纵钉杆221和第二纵钉杆孔223，
再将第一横套环112铆入第一横钉杆111，第二纵套环222铆入第二纵钉杆221，第一纵套环212铆入第一纵钉杆211，第二横套环122铆入第二横钉杆123。
根据本申请实施例的车辆2的其他构成对于本领域普通技术人员而言都是已知的，这里不再详细描述。在本说明书的描述中，参考术语“具体实施例”、“具体示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
