下面结合附图并参考具体实施例描述本公开：
如图1、图2、图3和图4所示，本公开一些实施例提供了一种前围总成，其可以包括前围板100、前风窗盖板200、隔音垫300以及连接件，用以降低由前机舱传递至驾驶舱内的噪音。前风窗盖板200固定设置于前围板100的上沿。前风窗盖板200一般通过点焊的方式固定设置于前围板100的上，并且焊缝贯穿前围板100的上沿，隔音垫300覆盖前风窗盖板200与前围板100之间的连接处，即隔音垫300覆盖焊缝。隔音垫300覆盖的焊缝多，隔音效果好，能够提升驾驶舱的NVH性能。可以理解的，当前风窗盖板200和前围板100采用其他连接方式致使前围板100和前风窗盖板200的连接处具有缝隙或者连接处薄弱，亦可应用本公开一些实施例以降低前机舱内的噪音。
前风窗盖板200的上端面沿长度方向可以依次间隔设置多个安装部，各个安装部的可以与连接件一一对应，安装部与连接件配合以将隔音垫300固定于前风窗盖板200上。为了保证隔音垫300的隔音效果，隔音垫300可经过塑形处理，以使隔音垫300贴合前风窗盖板200和前围板100的部分后侧壁，减少隔音垫300与前风窗盖板200和前围板100之间的间隙，提升隔音效果。在一些实施例中，前围板100的后侧壁为前围板100朝向驾驶舱的侧壁。在一些实施例中，安装部设置有沉降槽201或朝向驾驶舱的安装斜面202。通过沉降槽201或安装斜面202改变连接件的朝向以及连接件顶端的位置，从而加大了隔音垫300与前风挡玻璃之间的间距，以避让前风挡玻璃，且不影响前风挡玻璃的装配。这样，在保证隔音垫300与前围总成紧密连接的同时，降低了连接件对安装前风挡玻璃的影响。
在一些实施例中，前围板200的上端面沿长度方向可以依次间隔设置多个安装部，各个安装部可以与连接件一一对应，安装部与连接件配合以将隔音垫300固定于前风窗盖板200上。由此，前风窗盖板200的上端面沿长度方向的多个安装部，在装配过程中容易被识别，有助于提高装配效率以及防止装配错误。由于隔音垫300的覆盖面积大，能够向上延伸至前风挡玻璃的边缘处连接，使得隔音垫300的装配操作中各部件在外观上易被识别，从而有助于提高装配效率以及防止装配错误。
此外，由于具有沉降槽201或安装斜面202的安装部在电泳漆时不积气，使得前风窗盖板200表面光滑，从而能够与隔音垫300紧密贴合，获得较好的隔音效果。
在一些实施例中，在多个安装部中，位于前风窗盖板200的中部的安装部设置有沉降槽201，其余的安装部设置有朝向驾驶舱的安装斜面202，沉降槽201的槽底相较于安装斜面202更低。当连接件与沉降槽201连接时，连接件不会过多的突出于沉降槽201外，从而更利于前风挡玻璃的装配。风挡玻璃倾斜设置于前风窗盖板200上，安装斜面202与连接件连接时，连接件也朝驾驶舱倾斜，以远离前风挡玻璃。在一些实施例中，安装斜面202与对应的前风挡玻璃的切面之间夹角不小于90°，即当连接件与安装部连接时，连接件的顶端朝向驾驶舱且连接件的轴线与对应的前风挡玻璃的切面平行，或连接件的轴线与前风挡玻璃之间的间距沿远离前风窗盖板200的方向逐渐增大，以进一步降低连接件对前风挡玻璃装配的影响。
参照图1和图3，在一些实施例中，前风窗盖板200可以包括依次间隔设置第一安装部210、第二安装部220、第三安装部230和第四安装部240。第一安装部210、第三安装部230和第四安装部240均具有朝向驾驶舱的安装斜面202。第二安装部220设置有沉降槽201。考虑到后续操作台以及仪表盘等机构的装备，本公开一些实施例中，第二安装部220设置于 前风窗盖板200的上端面的中部，第一安装部210设置于驾驶位的前方，以便为仪表盘预留安装位置。副驾驶位前方一般不会安装其他机构，由此，第三安装部230和第四安装部240间隔设置于副驾驶位的前方，以增加副驾驶位前方的隔音垫300与前风窗盖板200连接的紧密度。
参照图3和图4，前风窗盖板200上端面中部宽、两端窄。在一些实施例中，为了保证安装斜面202的倾斜角度，头部和尾部的两个安装部的安装斜面202均和前风窗盖板200与前围板100之间的连接处相接，安装斜面202与焊缝平滑过渡，能够保证安装部在电泳漆时不积气，保障前风窗盖板200表面光滑易于与隔音垫相贴。
安装斜面202或沉降槽201上均可设置有螺孔，可以使用螺栓作为连接件。螺栓与螺孔螺纹连接即可完成隔音点的安装，但考虑到开设螺孔在一定程度上增加了前机舱与驾驶舱之间的间隙，由此，本公开一些实施例中，连接件可以包括螺柱400和螺母，螺柱400的一端与安装斜面202焊接，螺柱400与水平面之间的夹角为锐角；隔音垫300设置有多个与螺柱400一一对应的通孔，螺母将隔音垫300锁紧在安装斜面202和螺母之间。
在一些实施例中，为了便于作业人员焊接螺柱400，每个安装斜面202上或沉降槽201内均设置有与螺柱400的端面匹配的焊接定位点，焊接定位点可为圆槽，也可为凸出的圆环，圆环的内径不小于螺柱400的外径。
参照图4，前风窗盖板200的一侧与前围板100连接，前风窗盖板200的另一侧设置有风挡玻璃安装板203，隔音垫300与风挡玻璃安装板203边缘相接，增加隔音垫300的覆盖面积，进一步提升对前机舱噪声的隔离效果，提升车辆的NVH性能。
参照图4，在一些实施例中，风挡玻璃安装板203为斜面，风挡玻璃安装板203上与前风窗盖板200相对的一侧设置有朝向车身的底板的翻边204，翻边204可以增加风挡玻璃安装板203的强度，进而降低行车过程中前风窗盖板200晃动造成的隔音垫300与前风窗盖板200分离的情况，进而提升极限路况下，车辆的NVH性能。
在一些实施例中，前围板100一体成型，即前围板100上无焊缝，能减少因分割产生的前机舱密封不良的缺陷，前机舱的噪声不易透过前围板100传递至驾驶舱内，当然，可以理解的，一体成型的前围板100的强度高，前围板100自身不易发生晃动和异响，能进一步提升车辆的NVH性能，提高乘客的乘车体验。
在一些实施例中，可以通过钣金件冲压一体成型以形成一体成型的前围板100。一体成型获得前围板100的工艺过程中，加工工装例如模具和夹具等成本可以显著降低；分体式前围板所需的装配成本得以节省；此外，分体式前围板所需的连接件或连接结构得以省略，因此一体成型的前围板100的整体重量显著降低。
依据本公开一些实施例的技术方案至少具有如下有益效果：由上述技术方案可知，本公开提供的前围总成通过连接件将隔音垫安装在前风窗盖板上，以覆盖前风窗盖板与前围板之间的连接处，隔音垫覆盖的面积大，隔音效果好，能够提升驾驶舱的NVH性能；此外，多个安装部设置的安装斜面或沉降槽在保证隔音垫与前风窗盖板之间的连接的紧密性的同时，可避让前风挡玻璃，不影响风挡玻璃的安装。
