车身骨架接头和具有其的车辆
相关申请的交叉引用
本申请要求比亚迪股份有限公司于2019年8月30日提交的、申请名称为“车身骨架接头和具有其的车辆”的、中国专利申请号“201910812425.5”的优先权。
技术领域
本申请涉及车辆技术领域，尤其是涉及一种车身骨架接头和具有其的车辆。
背景技术
相关技术中诸如大型客车等车辆，其车身骨架通常含有横梁和纵梁等交叉连接的梁结构，横梁和纵梁的连接处采用接头进一步固定，其中，一些接头仅与横梁和纵梁的两个垂直面连接，该种接头的疲劳耐久强度不足，导致连接刚度不足，变形量较大；还有一些接头不仅与横梁和纵梁的两个垂直面连接，而且与横梁和纵梁的两侧面连接，该种接头本身的装配就较为麻烦，加之整车的装配精度要求较高，而对于制造误差和装配误差一些不可避免的因素，导致装配更加繁琐，严重影响装配效率。
发明内容
本申请旨在至少解决现有技术中存在的技术问题之一。
为此，本申请的一个目的在于提出一种车身骨架接头，该车身骨架接头不仅连接强度高，而且装配方便、装配效率高。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的车辆2。
如图1-图8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1-图2、图5-图6所示，根据本申请实施例的车身骨架接头1包括第一子接头10和和第二子接头20。
第一子接头10和第二子接头20适于安装在车身骨架上，具体为横梁30和纵梁40的连接处，第一子接头10和第二子接头20对合且共同限定出横梁连接槽310和纵梁连接槽(图中未示意)，横梁连接槽310适于容纳所述车身骨架的横梁30，所述纵梁连接槽适于容纳所述车身骨架的纵梁40。
需要说明的是，本申请中的“对合”指的是第一子接头10和第二子接头20彼此正对，二者合在一起以限定出横梁连接槽310和纵梁连接槽。第一子接头10和第二子接头20对合可以理解为第一子接头10和第二子接头20彼此正对且彼此贴合，当然本申请不限于此，第一子接头10和第二子接头20对合还可以理解为第一子接头10和第二子接头20彼此正对且间隔开，只要保证第一子接头10和第二子接头20正对在一起能够限定出横梁连接槽310和纵梁连接槽即可。
举例而言，第一子接头10和第二子接头20沿车身骨架接头1的宽度方向排布，第一子接头10和第二子接头20分别连接横梁30与纵梁40，且第一子接头10和第二子接头20关于车身骨架接头1的中心面镜像对称。横梁连接槽310和所述纵梁连接槽连通且可以垂直设置，横梁连接槽310沿车辆2的长度方向延伸，开口方向朝向车辆2的横梁30。所述纵梁连接槽沿车辆2的高度方向延伸，开口方向朝向车辆2的纵梁40。
根据本申请实施例的车身骨架接头1，通过设置分体的第一子接头10和第二子接头20， 使车身骨架接头1的结构相对简单、安装方便、单个铸件(第一子接头10和第二子接头20)开模简单，提高了生产效率。
并且，第一子接头10和第二子接头20对合且共同限定出横梁连接槽310和纵梁连接槽，这样可以利用横梁连接槽310容纳横梁30，且利用纵梁连接槽容纳纵梁40，使车身骨架接头1与横梁30和纵梁40形成多面定位，从而提高疲劳耐久强度，进而提高连接刚度，减小变形量。
此外，在保证连接刚度的情况下，由于车身骨架接头1为分体结构，这样在装配时可以分别安装第一子接头10和第二子接头20，最后对合夹持在横梁30和纵梁40的连接处，该种装配方式对整车装配精度要求较低，操作更加方便，能够大幅提高装配效率。
因此，根据本申请实施例的车辆2及车身骨架接头1，不仅连接强度高，而且具有加工方便、结构简单、生产效率高等优点。
根据本申请的一些具体实施例，如图1-图6所示，第一子接头10包括第一横梁连接板110、第一纵梁连接板120和第一侧板130。
第一横梁连接板110与第一纵梁连接板120相连，第一侧板130连接在第一横梁连接板110和第一纵梁连接板120的远离第二子接头20的一侧。
第二子接头20包括第二横梁连接板210、第二纵梁连接板220和第二侧板230。
第二横梁连接板210与第二纵梁连接板220相连，第二侧板230连接在第二横梁连接板210和第二纵梁连接板220的远离第一子接头10的一侧。
其中，第一横梁连接板110和第二横梁连接板210对合且与第一侧板130和第二侧板230共同限定出横梁连接槽310，第一纵梁连接板120和第二纵梁连接板220对合且与第一侧板130和第二侧板230共同限定出所述纵梁连接槽，横梁30和纵梁40被夹持在第一侧板130和第二侧板230之间。
举例而言，第一横梁连接板110、第一纵梁连接板120和第一侧板130可一体成型。第二横梁连接板210、第二纵梁连接板220和第二侧板230可一体成型。第一子接头10和第二子接头20可为铝合金材料构成。第一横梁连接板110和第一纵梁连接板120可与第一侧板130垂直，第一纵梁连接板120和第二纵梁连接板220可与第二侧板230垂直，第一侧板130可与第二侧板230平行。如此，车身骨架接头1与(横梁30的内外表面和下表面与纵梁40的内外表面和一侧面均有连接，稳定可靠，刚度和强度得到提高，提升了车身骨架的连接强度。第一子接头10和第二子接头20采用铝合金材料构成，可以减轻车辆2的整体重量。
进一步的，如图1-图7所示，第一横梁连接板110和第一纵梁连接板120垂直设置且两者的连接处倒斜角，第一侧板130为L形板。第二横梁连接板210和第二纵梁连接板220 垂直设置且两者的连接处倒斜角，第二侧板230为L形板。如此，第一横梁连接板110和第一纵梁连接板120的连接过渡平缓，第二横梁连接板210和第二纵梁连接板220的连接过渡平缓。第一侧板130和第二侧板230为L形板即保证了和车身骨架的连接面积，又节约了材料。
再进一步的，如图1-图5所示，第一侧板130和第二侧板230的厚度相同，第一横梁连接板110、第一纵梁连接板120、第二横梁连接板210和第二纵梁连接板220的厚度相同且大于第一侧板130和第二侧板230的厚度。如此，可以满足车身骨架接头1的强度要求和刚度要求，并且可以根据车身骨架的实际情况调整车身骨架接头1的结构。
根据本申请的一些具体实施例，如图2、图5-图7所示，第一侧板130和第二侧板230分别设有沉头钉孔131。第一侧板130通过配合于其沉头钉孔131内的沉头钉231安装于横梁30和纵梁40，第二侧板230通过配合于其沉头钉孔131内的沉头钉231安装于横梁30和纵梁40。
具体的，沉头钉孔131构造有沉槽，以使第一侧板130上的沉头钉231的外表面与第一侧板130的外表面平齐，且使第二侧板230上的沉头钉231的外表面与第二侧板230的外表面平齐。
举例而言，第一侧板130朝向第二侧板230的一侧面和第二侧板230朝向第一侧板130的一侧面分别与横梁30和纵梁40沿车辆2的宽度方向相对的两面连接，例如，第一侧板130朝向第二侧板230的一侧面连接于横梁30和纵梁40的朝向车辆2外侧的一面，第二侧板230朝向第一侧板130的一侧面连接于横梁30和纵梁40的朝向车辆2内侧的一面。如此，增加了车身骨架接头1和车身骨架的连接面积，提高了连接强度，沉头钉231和沉头钉孔131的配合，未影响车内的内饰布置。
根据本申请的一些实施例，如图5-图7所示，横梁30构造有第一横滑槽320和第二横滑槽330，纵梁40构造有第一纵滑槽420和第二纵滑槽430。第一横滑槽320和第二横滑槽330沿车辆2的长度方向延伸，第一纵滑槽420和第二纵滑槽430沿车辆2的高度方向延伸。
第一横梁连接板110设有第一横钉杆孔111，第一横钉杆孔111内配合有第一横钉杆112且第一横钉杆112上铆接有第一横套环113，第一横钉杆112可滑动地配合于第一横滑槽320，第二横梁连接板210设有第二横钉杆孔211，第二横钉杆孔211内配合有第二横钉杆212且第二横钉杆212上铆接有第二横套环213，第二横钉杆212可滑动地配合于第二横滑槽330。
第一纵梁连接板120设有第一纵钉杆孔121，第一纵钉杆孔121内配合有第一纵钉杆122且第一纵钉杆122上铆接有第一纵套环123，第一纵钉杆122可滑动地配合于第一纵滑槽 420，第二纵梁连接板220设有第二纵钉杆孔221，第二纵钉杆孔221内配合有第二纵钉杆222且第二纵钉杆222上铆接有第二纵套环223，第二纵钉杆222可滑动地配合于第二纵滑槽430。
如此，采用双滑槽的连接方式，不仅连接强度高，减小整车的变形及振动，提高整车耐久性能。而且在安装时便于车身骨架接头1的位置的调节，装配操作也更加方便。
进一步的，如图2和图5所示，第一横钉杆112套设有位于第一横钉杆112和第一横梁连接板110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320，第二横钉杆212套设有位于第二横钉杆212和第二横梁连接板210之间的第二横垫片214，第二横垫片214可滑动地配合于第二横滑槽330。第一横垫片114和第二横垫片214可以为铝合金材料制造。
第一纵钉杆122套设有位于第一纵钉杆122和第一纵梁连接板120之间的第一纵垫片124，第一纵垫片124可滑动地配合于第一纵滑槽420，第二纵钉杆222套设有位于第二纵钉杆222和第二纵梁连接板220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430。第一纵垫片124和第二纵垫片224可为铝合金材料制造。
举例而言，第一横垫片114、第一纵垫片124、第二横垫片214和第二纵垫片224分别为铝合金薄片，它们的中心线上开有通孔，用于安装第一横钉杆112、第一纵钉杆122、第二横钉杆212和第二纵钉杆222，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124、第二横垫片214和第二纵垫片224分别与第一横滑槽320、第一纵滑槽420、第二横滑槽330和第二纵滑槽430的槽底贴合。
如此，第一横垫片114、第一纵垫片124、第二横垫片214和第二纵垫片224采用铝合金材料，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124、第二横垫片214和第二纵垫片224与第一横滑槽320、第一纵滑槽420、第二横滑槽330和第二纵滑槽430的接触面承受载荷作用，可以消减第一横滑槽320、第一纵滑槽420、第二横滑槽330和第二纵滑槽430的应力集中，使车身骨架满足强度和变形的要求。
根据本申请的一些实施例，如图2、图5-图7所示，第一横梁连接板110上的第一横钉杆孔111为多个，第二横梁连接板210上的第二横钉杆孔211为多个，第一纵梁连接板120上的第一纵钉杆122为多个，第二纵梁连接板220上的第二纵钉杆222为多个。
根据本申请的一些实施例，如图1-图5所示，第一横梁连接板110的内侧表面和第一纵梁连接板120的内侧表面设有第一内筋140，第一横梁连接板110上的第一内筋140与第一纵梁连接板120上的第一内筋140通过第一拐角筋150相连，第一拐角筋150位于第一 横梁连接板110和第一纵梁连接板120的连接处。
第二横梁连接板210的内侧表面和第二纵梁连接板220的内侧表面设有第二内筋240，第二横梁连接板210上的第二内筋240与第二纵梁连接板220上的第二内筋240通过第二拐角筋250相连，第二拐角筋250位于第二横梁连接板210和第二纵梁连接板220的连接处。
具体的，第一拐角筋150的厚度大于第一内筋140的厚度，第二拐角筋250的厚度大于第二内筋240的厚度。
进一步的，如图1-图5所示，第一横梁连接板110上第一内筋140位于第一横梁连接板110的宽度方向上的中心处，第二横梁连接板210上第二内筋240位于第二横梁连接板210的宽度方向上的中心处，第一纵梁连接板120上第一内筋140位于第一纵梁连接板120的宽度方向上的中心处，第二纵梁连接板220上第二内筋240位于第二纵梁连接板220的宽度方向上的中心处。
如此，第一内筋140、第二内筋240、第一拐角筋150和第二拐角筋250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。第一内筋140、第一拐角筋150、第二内筋240和第二拐角筋250分别位于第一横梁连接板110、第一纵梁连接板120、第二横梁连接板210和第二纵梁连接板220的宽度中心，使车身骨架接头1的受力均匀合理，且结构强度更高。
根据本申请的一些实施例，如图1-图7所示，第一横钉杆孔111贯通第一横梁连接板110上的第一内筋140，第一横梁连接板110上的第一内筋140配合于第一横滑槽320，第一纵钉杆孔121贯通第一纵梁连接板120上的第一内筋140，第一纵梁连接板120上的第一内筋140配合于所述第一纵滑槽420，第一拐角筋150配合于第一横滑槽320和第一纵滑槽420的连接处；
第二横钉杆孔211贯通第二横梁连接板210上的第二内筋240，第二横梁连接板210上的第二内筋240配合于第二横滑槽330，第二纵钉杆孔221贯通第二纵梁连接板220上的第二内筋240，第二纵梁连接板220上的第二内筋240配合于第二纵滑槽430，第二拐角筋250配合于第二横滑槽330和第二纵滑槽430的连接处。
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150插入第一横滑槽320和第一纵滑槽420，第二拐角筋250插入第二横滑槽330和第二纵滑槽430，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140插入第一横滑槽320和第一纵滑槽420，第二内筋240插入第二横滑槽330和第二纵滑槽430，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。
根据本申请的一些实施例，如图1-图7所示，第一横梁连接板110的外侧表面和第一纵梁连接板120的外侧表面设有位于两者连接处的第一外筋160，第一外筋160倒圆角。第二横梁连接板210的外侧表面和所第二纵梁连接板220的外侧表面设有位于两者连接处的第二外筋260，第二外筋260倒圆角。
换言之，第一外筋160连接第一横梁连接板110和第一纵梁连接板120，第二外筋260连接第二横梁连接板210和第二纵梁连接板220。第一外筋160与第一横梁连接板110和第一纵梁连接板120连接的部分倒圆角，第二外筋260与第二横梁连接板210和第二纵梁连接板220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1-图5所示，第一外筋160为多个且沿第一横梁连接板110和第一纵梁连接板120的宽度方向间隔设置，第二外筋260为多个且沿第二横梁连接板210和第二纵梁连接板220的宽度方向间隔设置。
举例而言，第一外筋160为两个，一个设置在与第二子接头20靠近的一侧，且所述一个第一外筋160的外侧平面与第一子接头10的第一侧板130的外侧平面平齐，另一个设置在远离第二子接头20的一侧，且所述另一个第一外筋160的外侧平面与第一子接头10的第一横梁连接板110的远离第一侧板130的一侧边沿平齐，所述一个第一外筋160的尺寸小于所述另一个第一外筋160的尺寸。第二外筋260为两个，一个设置在与第一子接头10靠近的一侧，且所述一个第二外筋260的外侧平面与第二子接头20的第二侧板230的外侧平面平齐，另一个设置在远离第一子接头10的一侧，且所述另一个第二外筋260的外侧平面与第二子接头20的第一纵梁连接板120的远离第二侧板230的一侧边沿平齐，所述一个第二外筋260的尺寸小于所述另一个第二外筋260的尺寸。
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。第一外筋160和第二外筋260的尺寸设计，便于第一横梁连接板110、第一纵梁连接板120、第二横梁连接板210和第二纵梁连接板220开设第一横钉杆孔111、第一纵钉杆孔121、第二横钉杆孔211和第二纵钉杆孔221。
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112，第一纵垫片124套入第一纵钉杆122，第二横垫片214套入第二横钉杆212，第二纵垫片224套入第二纵钉杆222，再将带有垫片的第一横钉杆112和第二横钉杆212分别滑入横梁30的第一横滑槽320和第二横滑槽330，带有垫片的第一纵钉杆122和第二纵钉杆222分别滑入纵梁40的第一纵滑槽420和第二纵滑槽430。
