Description

后轮罩外板总成及车辆 技术领域
本发明涉及车辆技术领域，特别是涉及一种后轮罩外板总成及车辆。
背景技术
后轮罩外板总成是车辆车身侧围总成的一个重要零部件。车辆的车身后轮罩区域作为车身锈蚀的高风险区，需要保持良好的密封性能，防止外部液体进入到后轮罩内部而产生锈蚀，继而引发用户抱怨。传统燃油车辆的车身通过加油口盒分别连接车身及侧围外板，在加油口盒零件与车身和侧围外板连接时存在两处密封部，其中一个密封部是加油口盒与车身连接处的密封部，另一个密封部是加油口盒与侧围外板连接处的密封部。在车辆使用过程中，密封部老化或者损坏可能会增加车身漏水风险。此外，现有技术中，轮罩外板单件由于回弹筋的布置不合理导致底部圆角过渡不顺，易产生冲压成型起皱问题。
发明内容

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1是根据本发明一个实施例的后轮罩外板总成100与侧围外板200和侧围后部内板总成300连接的示意性***图。
如图1所示，本实施例中的后轮罩外板总成100的前侧与侧围外板200连接，后侧与侧围后部内板总成300连接。具体地，本实施例的后轮罩外板总成100与侧围后部内板总成300之间可以通过点焊的方式连接，当然也可以采用其它连接方式，例如通过紧固件连接等方式进行连接。
图2是根据本发明一个实施例的本体的示意性结构图。如图1和图2所示，本实施例中的后轮罩外板总成100可以包括本体10，该本体10可以包括充电口11，该充电口11的外周处设置粘胶，本体10可以直接通过粘胶与侧围外板200连接。
本实施例中，后轮罩外板总成100和侧围外板200之间取消了加油口盒部件的设计，直接将后轮罩外板总成100与侧围外板200之间采用粘胶连接，将现有的两个密封部减少为一个密封部，降低了车辆在使用过程中因密封部老化或损坏而出现漏水现象的概率，降低了车身后轮罩区域发生锈蚀的风险，提高车辆质量，进而提高用户的使用体验。
作为本发明一个具体的实施例，本实施例的充电口11外周处设置有胶槽12，粘胶涂设于胶槽12内。本实施例中的粘胶可以为膨胀胶，膨胀胶在涂装时经过高温发泡与侧围外板200连接。本实施例中的膨胀胶是以合成橡胶及树脂为基材的汽车专用膨胀胶带或胶片，具有优良的油面粘接性、可操作性、高膨胀率、填充性、弹性及良好的附着性。该膨胀胶可适 用于汽车钣金与加强筋、骨架、支撑架之间的减震粘接，还可以适用于车门、车身外板、发动罩盖外板与骨架等的减震粘接。本实施例中在后轮罩外板总成100和侧围外板200之间利用膨胀胶进行密封连接，既具有粘连密封作用，又具有减震作用，使后轮罩外板总成100和侧围外板200之间非刚性密封连接。
具体地，本实施例的后轮罩外板总成100采用膨胀胶设置在胶槽12内，再利用膨胀胶在高温发泡时与侧围外板200连接，既能保证后轮罩外板总成100和侧围外板200密封连接，又能保证在车辆后续使用过程中不会掉胶，延长使用寿命。
本实施例中采用将膨胀胶设置在胶槽12内将后轮罩外板总成100和侧围外板200进行连接仅仅作为本发明一个较优选的实施例，在其它实施例中，胶槽12的结构可以多样化，也可以取消胶槽12结构。同样地，在其它实施例中，可以将膨胀胶更换为其它具有相同或者相似的性能的粘胶。
作为本发明一个具体的实施例，本体10可以包括支撑部13和桥接部14。其中，支撑部13由长板状结构弯曲形成与车轮适应的形状。具体，支撑部的截面形成一个长边开口向下的梯形结构。桥接部14与支撑部13的一个端部a连接，并与支撑部13之间呈第一预设角度，充电口11设置于桥接部14处。其中，第一预设角度可以为90-120°。例如，第一预设角度可以为90°、100°或120°。
具体地，本实施例中，支撑部13和桥接部14连接处为圆角设计，便于成型。
作为本发明一个具体的实施例，本实施例的支撑部13处设置有特征筋15，特征筋15的底部所在平面与特征筋15所在位置的支撑部13表面的夹角呈第二预设角度。其中，第二预设角度为2-6°。例如，第二预设角度可以为2°、3°、4°或6°。本实施例中在支撑部13处设置特征筋15可以增加支撑部13的强度。
作为本发明一个具体的实施例，本实施例支撑部13在与桥接部14相反的一端b设置有翻边16。该翻边16沿着远离充电口11的方向延伸，并且翻边16基本上与充电口11所在的平面平行。本实施例中，翻边16与支撑部13连接处为圆角设计。
图3是根据本发明一个实施例的后轮罩外板总成的示意性***图；图4是图3中沿剖切线A-A进行剖切后的截面图。具体地，本实施例中，如图4所示，定义与翻边16垂直的平面为基准面。将支撑部13沿着剖切线A-A进行剖切后可以看出，特征筋15的截面与基准面之间的夹角α可以为3-5度，例如α可以是3°、4°或5°。另外，本体10的支撑部13的表面的截面和基准面之间的夹角β可以是7-9°。例如，β可以是7°、8°或9°。因此，特征筋15的底部所在平面与特征筋15所在位置的支撑部13表面的夹角呈第二预设角度就为α与β的差值。
作为本发明一个具体的实施例，本发明实施例的特征筋15设置在支撑部13的中部位置，特征筋15与翻边16之间的最小距离为预设距离，其中，预设距离大于0。也就是，特征筋15与翻边16和支撑部13的连接处的圆角之间具有一定的距离。
本实施例中，特征筋15的成型角度α与支撑部13的成型角度β有一定的差别，同时特征筋15不延伸至翻边16和支撑部13的连接处的圆角处，既防止了后轮罩外板总成100的回弹又避免了特征筋15延伸至圆角而产生起皱的问题。
本实施例中，特征筋15的数量为多个，沿支撑部13的宽度方向延伸，并排设置在支撑部13处。例如，图2和图3中所示，支撑部13的梯形结构的两边腰部处均设置有5个特征筋15。当然，特征筋15的具体数量可以根据实际的需要进行自由设计。
图5是根据本发明一个实施例的后轮罩外板总成的示意性结构图；图6是图5中沿剖切线B-B进行剖切后的截面图。在实际使用过程中，后轮罩外板总成100与充电口安装支架400连接(如图8和图10所示)。该充电口安装支架400通过后轮罩外板总成与车辆的侧围外板连接。作为本发明一个具体的实施例，如图3和图5所示，本实施例的后轮罩外板总成100还可以包括上安装支架20和下安装支架30。其中，上安装支架20可以与本体10连接，设置在充电口11的上方，且位于本体10的与侧围外板200相反的一侧处。下安装支架30可以与本体10连接，设置在充电口11的下方，且位于本体10的与侧围外板200相反的一侧处。其中，上安装支架20和下安装支架30均与充电口安装支架400连接。将充电口安装 支架400连接在后轮罩外板总成100处。且充电口安装支架400所在平面与充电口所在平行基本上平行。
图7是根据本发明一个实施例的上安装支架的示意性结构图；如图7所示，作为本发明一个具体的实施例，上安装支架20可以包括第一连接部21和第二连接部22。第一连接部21与支撑部13连接。具体地，第一连接部21与支撑部13连接处的结构可以与支撑部13的结构相适应。并且第一连接部21与支撑部13之间可以通过焊接或者利用紧固件连接在一起。本实施例中，第一连接部21与支撑部13之间优选通过点焊的方式连接在一起。
此外，第二连接部22的一端与第一连接部21的一端连接，另一端朝向下安装支架30的方向延伸，直至与充电口安装支架400的一端连接。具体地，第二连接部22延伸的方向与充电口安装支架400所在平面基本上平行，便于第二连接部22与充电口安装支架400连接。
具体地，本实施例中第一连接部21和第二连接部22之间连接处为弯曲结构，该弯曲结构可以根据实际的需要进行自由设计。
图8是根据本发明一个实施例的上安装支架和下安装支架与国标的充电口安装支架连接的示意性结构图。作为本发明一个具体的实施例，本实施例中的第二连接部22处设置有两个第一安装点221。充电口安装支架400处设置有与两个第一安装点221配合的两个第二安装点(图8中被第一安装点221覆盖)。第二连接部22与充电口安装支架400利用紧固件在第一安装点221和第二安装点处将第二连接部22和充电口安装支架400连接在一起。
在其中一个实施例中，第一安装点221与第二安装点均为通孔，紧固件则穿过通孔将第二连接部22和充电口安装支架400进行紧固连接。
在实际安装过程中，由于第二连接部22和充电口安装支架400进行安装时的空间狭小，作为优选的一个实施例，本实施例中第一安装点221处焊接有螺栓或螺柱，第二安装点为通孔。在充电口安装支架400与第二连接部22连接时，直接将螺栓或螺柱穿过通孔，再利用螺母进行紧固。
具体地，本实施例的第一连接部21处设置有第一加强筋211，至少部分第一加强筋211延伸至第二连接部22处。具体地，第一连接部21处 设置多条第一加强筋211，而位于中间位置的第一加强筋211延伸至第二连接部22处。第一加强筋211的作用是为了增加第一连接部21和第二连接部22的强度。
具体地，本实施例中的第二连接部22处的两个第一安装点221位于延伸至第二连接部22处的第一加强筋211的两侧。
作为本发明一个具体的实施例，本实施例中的第二连接部22处还设置有第一夹持面222，第一夹持面222在沿着第一方向上的尺寸为15-18mm，例如第一夹持面222在沿着第一方向上的尺寸可以是15mm、16mm或18mm。第一方向为第二连接部22在使用时上下两个端部的连接方向。具体地，本实施例的第一方向优选为上安装支架20在使用过程中的第一夹持面222的纵截面的方向。例如图6中的C所示方向。
图9是根据本发明一个实施例的下安装支架的示意性结构图。作为本发明一个具体的实施例，如图9所示，下安装支架30可以包括第三连接部31和第四连接部32。本实施例中的第三连接部31与桥接部14连接。具体地，第三连接部31与桥接部14连接处的结构可以与桥接部14的结构相适应。并且第三连接部31与桥接部14之间可以通过焊接或者利用紧固件连接在一起。本实施例中，第三连接部31与桥接部14之间优选通过点焊的方式连接在一起。
具体地，第四连接部32的一端与第三连接部31的一端连接，另一端朝向上安装支架20的方向延伸，直至与充电口安装支架400的另一端连接。具体地，第四连接部32延伸的方向与充电口安装支架400所在平面基本上平行，便于第四连接部32与充电口安装支架400连接。
具体地，本实施例中第三连接部31和第四连接部32之间连接处为弯曲结构，该弯曲结构可以根据实际的需要进行自由设计。
具体地，本实施例中第四连接部32处设置有三个第三安装点321。充电口安装支架400处设置有与其中两个第三安装点321配合的两个第四安装点(图8中被第三安装点遮挡)。第四连接部32与充电口安装支架400利用紧固件在第四安装点和其中两个第三安装点321处将第四连接部32和充电口安装支架400连接在一起。
本实施例中，因充电口安装支架400分为国标和欧标，而国标和欧标 中第四安装点的位置略有不同，因此在第四连接部32处分别设置有与国标充电口安装支架400的第四安装点配合的第三安装点321，还设置有与欧标充电口安装支架400的第四安装点配合的第三安装点321，从而使下安装支架30既适用于国标的充电口安装支架，也适用于欧标的充电口安装支架。
图10是根据本发明一个实施例的上安装支架和下安装支架与欧标的充电口安装支架连接的示意性结构图。如图8所示，当适配国标充电口安装支架400时，第四连接部32利用两侧的第三安装点321与充电口安装支架400上的第四安装点配合使用。如图10所示，当适配欧标充电口安装支架400时，第四连接部32利用右侧的两个第三安装点321与充电口安装支架400上的第四安装点配合使用。
本实施例中上安装支架20上的两个第一安装点221配合下安装支架30上的三个第三安装点321，满足国标、欧标等不同的标准平台充电口安装支架400的安装功能，实现车身共用。这解决了国标和欧标充电口安装支架400的尺寸不同而使得安装点位置不同，需要车身区分配置的问题，避免了现场车身识别错装的风险。
具体地，本实施例中第三安装点321和第四安装点可以是通孔，再利用螺栓或螺柱等穿过通孔与螺母配合紧固，从而将充电口安装支架400和下安装支架30连接。作为其它实施例，由于在实际紧固安装过程中，受到空间限制，第三安装点321处可以先焊接有螺栓或螺柱，而充电口安装支架400处的第四安装点为通孔。在安装时，直接将充电口安装支架400的通孔与焊接螺栓或螺柱配合，再利用螺母进行紧固，保证安装的可靠性。
具体地，第三连接部31处设置有第二加强筋311，第二加强筋311沿着第二方向延伸，其中，第二方向为下安装支架30在使用状态时的第三连接部31处的上下端部连接的方向。具体地，第二加强筋311数量为多条。第二方向优选为在下安装支架30在使用过程中时，第三连接部31的纵向截面方向。如图6中的D所示方向。
作为本发明一个具体的实施例，本实施例中的第四连接部32处设置有第二夹持面322，第二夹持面322在沿着第三方向上的尺寸为15-18mm，例如尺寸可以为15mm、16mm或18mm。第三方向为第四连接部32在使 用状态时上下两个端部的连接方向。具体地，第三方向优选为在下安装支架30在使用状态下，第二夹持面322的纵向截面的方向。本实施例中，第三方向与第一方向基本上相同，均为图6中的C所示方向。
本实施例中，在上安装支架20和下安装支架30上均设置有一定尺寸的夹持面，利于上安装支架20和下安装支架30设置在后轮罩外板总成100的焊接夹持，保证了上安装支架20和下安装支架30与后轮罩外板总成100焊接的可行性，同时保证了安装点的尺寸稳定性。
作为本发明一个具体的实施例，本实施例还提供一种车辆，该车辆包括上面的后轮罩外板总成100。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
