一种用于车身后部的连接结构及汽车
交叉引用

技术领域
本公开涉及汽车零部件技术领域，尤其涉及一种用于车身后部的连接结构及汽车，具体涉及一种能够有效提高车身局部刚性并且提高焊接的可操作性的用于车身后部的连接结构及汽车。
背景技术
图1是示出了汽车白车身的立体图，白车身是指完成焊接但未涂装之前的车身，其不包括四门两盖等运动件。根据现有技术已知一种用于车身后部的连接结构，该连接结构位于车身后部的汽车C柱附近，其中汽车C柱是指汽车侧围立柱中贯穿于顶盖和下车体的第三根立柱。
图2是图1中的白车身沿平面A-A截取的示出了根据现有技术的用于车身后部的连接结构的截面示意图。根据现有技术的连接结构包括C柱加强板210、后轮罩外板220、置物架230和C柱内板240，其中C柱加强板210在连接区域215处与后轮罩外板220连接，而置物架230与C柱内板240连接。
然而，根据现有技术的用于车身后部的连接结构存在如下缺陷：首先，该连接结构的刚性不足，当汽车车身与外部障碍物发生碰撞时，特别是发生侧向碰撞时，该连接结构由于局部刚性不足够大而容易发生剧烈变形，从而破坏车身结构，并且更严重地可能导致汽车后排乘客受伤；其次，这种连接结构使得后轮罩外板具有很大的倾斜度，在将C柱加强板与后轮罩外板在连接区域处连接时会由于连接区域呈明显的锐角而增大连接时的难度，降低操作的可行性；此外，置物架和C柱加强板的腔体不够平滑，不利于车身后部的力传递，从而不利于车身后部的振动模型和动态刚性。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施 例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
如前文已描述过的，图1是示出了汽车白车身的立体图，并且图3是根据本公开的一种用于车身后部的连接结构的实施例的结构示意图。
如图3所示，本公开的实施例提供了一种用于车身后部的连接结构，该连接结构包括C柱加强板310、后轮罩外板320和位于汽车后座后方的置物架330，其中置物架330在其侧边的上部与C柱加强板310连接，置物架330在其侧边的下部与后轮罩外板320连接，C柱加强板310的底部与后轮罩外板320的上端连接。由于置物架330分别与C柱加强板310和后轮罩外板320直接连接，使得置物架、C柱加强板和后轮罩外板这三个部件之中两两均彼此连接，从而大大提高了至少包括置物架、C柱加强板和后轮罩外板在内的该连接结构处的局部刚性。特别地，当汽车车身与外部障碍物发生侧向碰撞时，由于这种局部刚性的提升，可以有效地降低车身的变形程度，从而更好地保护车身的各个部件以及后排乘客的安全。
通常，在车身的两个后轮罩外板320中的至少一个上包括为汽车加燃料时提供的燃料箱盖，例如油箱盖。因此，后轮罩外板320的上边缘需要布置为高于该油箱盖，这使得后轮罩外板320在外侧的高度受限于相对较高的位置。然而，根据本公开实施例，将后轮罩外板320与置物架330连接在一起使得后轮罩外板320在车身内侧方向的高度与现有技术的后轮罩外板220相比更高，因而在无法进一步降低后轮罩外板在外侧的高度的情况下，根据本公开实施例的后轮罩外板320使得其相对于水平平面的倾斜度更小。以这样的方式，C柱加强板310的侧面可以与后轮罩外板320之间在焊接区域315处形成更大的夹角。如此，当操作人员使用焊枪或例如焊接臂的自动装置将C柱加强板310和后轮罩外板320焊接在一起时，该更大的夹角有助于为操作人员和焊接臂提供更大的操作空间，从而降低焊接的难度，提高焊接的可操作性。此外，由于车身内部空间和车轮位置的限制，C柱加强板310的侧面与后轮罩外板320之间的夹角也不宜过大，C柱加强板310可垂直于后轮罩外板320设置。
根据实施例，C柱加强板310与后轮罩外板320的上部可以以各种适于装配车身的方式连接在一起。然而，出于车身轻量化、连接成本以及连 接可行性的原因考虑，C柱加强板310与后轮罩外板320的连接方式可以为焊接。更具体地，C柱加强板310在下部与后轮罩外板320的上端焊接的焊接区域315中设有贴合于后轮罩外板320上的翻边，C柱加强板310通过该翻边与后轮罩外板320焊接。翻边可以是不连续的，以节省材料从而降低制造成本。
可选地，置物架330与C柱加强板310焊接，后轮罩外板320与置物架330焊接。
根据实施例，C柱加强板310可以是一中空结构件，且C柱加强板310的横剖面的形状为U型，从而轻量化车身。此外，可以采用成型钢板来制造C柱加强板310，以进一步提高C柱加强板的刚性从而提高连接结构的局部刚性。
具体地，用于车身后部的该连接结构还包括C柱内板340、后轮罩前板350、后轮罩内板360和车身侧板370。C柱内板340和车身侧板370与C柱加强板310的连接方式可以为焊接，后轮罩前板350与后轮罩外板320和后轮罩内板360的连接方式也为焊接。相比于铆接和螺接的方式，采用焊接的方式有助于轻量化车身并降低装配成本。
另外，如图3所示的虚线箭头所示，置物架330、C柱加强板310和后轮罩外板320这三个部件之中两两均彼此焊接在一起，从而增加了力的传递路径，优化了车身后部的振动模型和动态刚性。
根据实施例，置物架330包括置物架主体331和置物架托架332，置物架主体331和置物架托架332整体为一中空结构件，且置物架330的纵剖面的形状为平行四边形，这有助于轻量化车身并且在一定程度上增加置物架承载物品的能力。
另一方面，本公开还提供了一种汽车，其包括如前文所描述的用于车身后部的连接结构。这种汽车在车身后部的连接结构处的局部刚性大大提高，优化了焊接的可操作性并且有效增加了力的传递路径以提高车身的动态刚性。
综上所述，本公开提供了一种用于车身后部的连接结构，其特征在于，包括C柱加强板、后轮罩外板和位于汽车后座后方的置物架；所述置物架在其侧边的上部与所述C柱加强板连接，所述置物架在其侧边的下部与所 述后轮罩外板连接，所述C柱加强板的底部与所述后轮罩外板的上端连接。由于置物架分别与C柱加强板和后轮罩外板直接连接，使得置物架、C柱加强板和后轮罩外板这三个部件之中两两均彼此连接，从而大大提高了至少包括置物架、C柱加强板和后轮罩外板在内的该连接结构处的局部刚性，提高了车身的安全性。
最后应说明的是：以上实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开各实施例技术方案的精神和范围。
