Description

车身顶盖外板与天窗加强板的配合结构、车身顶盖及汽车 技术领域
本发明涉及汽车制造技术领域；具体地说，本发明涉及一种车身顶盖外板与天窗加强板的配合结构，并进一步涉及一种包括这种配合结构的车身顶盖及汽车。
背景技术
现在一些汽车的车型中提供了天窗，一般为电动天窗，还包括全景天窗等。为了布置天窗，通常在车身顶盖外板上需要预形成有天窗开口，天窗总成安装至该天窗开口。
考虑到强度、密封性、加工工艺等要求，天窗开口处通常由车身顶盖外板与天窗加强板通过结构胶粘合而成，并且装有密封条。为了防止在涂装工艺中结构胶软化脱开，目前车身顶盖外板与天窗加强板配合通常采用两种辅助连接方式，一种是在车身顶盖外板和天窗加强板的重叠边处进行点焊；另一种是使用车身顶盖外板对天窗加强板进行包边。
这两种连接方式分别具有各自的缺点。点焊的缺点是会导致结合面不平整，从而影响天窗密封条与钣金配合面的匹配，引发天窗漏水问题；另外，点焊还存在焊接飞溅导致外观问题。包边工艺则需要非常昂贵的包边设备，并且有些钣金件在包边时易于产生破裂。
发明内容
本发明要解决的技术问题是提供一种能够克服现有技术中的前述缺陷的车身顶盖外板与天窗加强板的配合结构。
进一步地，本发明要解决的技术问题还在于提供一种包括前述配合结构的车身顶盖及汽车。
为了实现前述目的，本发明的第一方面提供了一种车身顶盖外板与天窗加强板的配合结构，其中，所述车身顶盖外板具有用于安装天窗的开口，所述天 窗加强板在所述车身顶盖外板的下方沿所述开口的周边粘合至所述车身顶盖外板，并且
所述车身顶盖外板在所述开口的边缘设置有向下弯折形成的第一保持部及延伸自所述第一保持部的密封条卡接部；
所述天窗加强板包括第二保持部，所述第二保持部固定至所述车身顶盖外板的所述第一保持部。
可选地，在如前所述的配合结构中，所述密封条卡接部为自所述第一保持部沿横向弯折延伸的内翻边。

为了实现前述目的，本发明的第三方面提供了一种汽车，其中，所述汽车采用如前述第二方面中所述的车身顶盖。
附图说明
参照附图，本发明的公开内容将更加显然。应当了解，这些附图仅仅用于说明的目的，而并非意在对本发明的保护范围构成限制。图中：
图1是一种具有天窗开口的车身顶盖外板的示意图；
图2是根据本发明的一种实施方式的车身顶盖外板与天窗加强板的配合结构的截面示意图；以及
图3是图2中的配合结构与汽车天窗接合处的截面示意图。
具体实施方式
下面参照附图详细地说明本发明的具体实施方式。在各附图中，相同的附图标记表示相同或相应的技术特征。可以了解，各附图均为示意的目的，而并未按比例绘制。
图1是一种具有天窗开口的车身顶盖外板的示意图。依据图1，在车身顶盖外板1上形成有方形的天窗开口2，汽车天窗(未图示)适于装配至该开口处。该示例中天窗开口的尺寸适用于安装全景天窗；但可以了解，本发明同样适用于一般的电动天窗。所属领域的技术人员也可以考虑到天窗开口的其它形状。
通常来说，在闭合状态下，天窗完全遮蔽住天窗开口；在打开时，天窗向着车身顶盖的后上方或后下方滑移，敞开天窗开口的至少一部分，实现换气、透光及调节车内气温等功能。
天窗加强板可以沿着天窗开口的周边固定在车身顶盖外板下，其具体可以为与车身顶盖外板中的天窗开口的形状相匹配的框架结构，在天窗位置对车身顶盖起到加固的作用，防止其在车辆正常使用及受到冲击时发生变形，保障车内安全以及车身顶盖附件的各项功能的正常使用。
图2是根据本发明的一种实施方式的车身顶盖外板与天窗加强板的配合结构的截面示意图，该截面示意图是在相应于图1中A-A的位置处截取的。依据本发明的教示，所属领域的技术人员可以了解，在天窗的整周上，车身顶盖外板与天窗加强板的配合结构可以具有类似的截面，通过结构的整体性来提供一致的加工工艺、强度及密封等各方面的性能。
结合图1和图2可以理解，天窗加强板120在车身顶盖外板110的下方沿开口的周边粘合至车身顶盖外板110。如图2中，车身顶盖外板110的天窗开口周边处的部位113与天窗加强板120的处于天窗开口周边处的部位122粘合在一起。例如，此处的粘合可以是通过结构胶实现的，具有强度高、在预期寿命内性能稳定等特点。在成品的汽车中可以主要依靠此处的粘合将身顶盖外板与天窗 加强板二者保持在一起。
由于该处的粘合需要在焊装车间中完成，所以，为了防止胶合部位在涂装车间内的烘烤等过程中软化脱开，本发明中的车身顶盖外板与天窗加强板的配合结构采用了具有有利构型的连接结构。具体地，如图2中所示，车身顶盖外板110在开口的边缘设置有向下弯折形成的第一保持部111及延伸自第一保持部111的密封条卡接部112，而天窗加强板120包括第二保持部121，并且第二保持部121固定至第一保持部111。通过在焊装车间中将第二保持部121固定至第一保持部111，保证了在汽车制造过程中车身顶盖外板110和天窗加强板120之间的相互位置，防止车身顶盖外板和天窗加强板之间的胶合部位在涂装车间内的烘烤等过程中软化时脱开。这样，在离开涂装车间后，前述胶合部位将固化并且恢复胶合力，车身顶盖在天窗处的强度不受影响。
结合图示可以了解，本实施方式中的第一保持部111、密封条卡接部112及第二保持部121均可以由正常的模具翻边工艺形成，而不必采用任何包边设计。由于不必采用包边工艺，所以不需要任何的包边设备，也不会产生任何包边破裂的问题，在全铝车身顶盖的情况下效果更加明显。这不仅降低了成本投入，而且提高了成品率。
依据图2的实施方式，密封条卡接部112可以为自第一保持部111沿横向弯折延伸的内翻边，不仅便于翻边加工，而且能够便于将密封条卡接于其上(见图3)。
第二保持部121为天窗加强板120上靠近第一保持部111的向下弯折的翻边，适于提供更大的重叠面积，能够便于其与第一保持部111的有效的固定连接。为了在保证连接(例如CMT)强度的同时尽量减少占用空间，第一保持部111的高度可以为7毫米至11毫米，第二保持部121的高度可以为3毫米至7毫米，密封条卡接部112的宽度可以为3毫米至5毫米。例如，在一种具体的实施方式中，第一保持部11的高度为可以9毫米，第二保持部121的高度可以为5毫米，密封条卡接部112的宽度可以为4毫米。
在可选的实施方式中，第一保持部111和第二保持部121之间可以通过冷金属过渡焊接技术(CMT)固定。冷金属过渡焊接技术是一种无焊渣飞溅的焊接工艺技术，不会造成任何外观问题；同时焊接部位平整度好，不会影响天窗密 封条与钣金配合面的匹配，保证了对雨水等的密封性能。在图2中用小圆圈示出了第一保持部111和第二保持部121之间的冷金属过渡焊接130的示意位置。
图3是图2中的配合结构与汽车天窗接合处的截面示意图。如图中所示，天窗处于闭合状态，完全遮蔽车身顶盖上的天窗开口。
依据图示，密封条卡接部112上卡接有天窗密封条140，该密封条140包围在天窗开口的内周上。在天窗玻璃200的周缘上安装有另一自带的密封条210。在该闭合状态下，密封条140和密封条210相抵接的过盈配合能够提供非常好的天窗密封性能。可以了解，在天窗开口及天窗玻璃相接合的整周上可以均设置成类似的结构。
图中在车身顶盖110、天窗加强板120及天窗玻璃200的下方还示出了天窗控制机构，所属领域的技术人员可以根据需要对其进行具体的结构设置，此处不再赘述。
基于以上结合图1至图3的描述，所属领域的技术人员可以得到包括如前述的车身顶盖外板与天窗加强板的配合结构的车身顶盖，并进一步得到采用如这种车身顶盖的汽车。可以理解，这样的车身顶盖和汽车的天窗结构能够得到天窗加强板的有效加强，并且制造成本更低、密封效果更好、成品率更高。
在一种实施方案中，天窗加强板与天窗配成一体，车身顶盖外板的天窗开口区域可以垂直翻边完后再横向延伸一条边，天窗加强板与顶盖外板之间采用玻璃胶粘接，天窗密封条直接与顶盖垂直翻边匹配。在这种方案的车身顶盖外板与天窗加强板的配合结构中，车身顶盖外板的天窗开口的边缘处具有向下弯折的垂直翻边，并且自该垂直翻边弯折延伸有横向边缘，天窗加强板用玻璃胶粘合至车身顶盖外板。这种方案具有接合面平整、高成低、成品率高等优点。
本发明的技术范围不仅仅局限于上述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对上述实施方式进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
