Description

亮条包边总成产品及其与外部部件的连接方法 技术领域
本发明涉及汽车装饰技术领域，尤其涉及一种亮条包边总成产品及其与外部部件的连接方法。
背景技术
随着汽车技术的发展，消费者对汽车的美观性提出了更高的要求。车用亮饰条作为一种汽车的装饰品，能够从整体上提高汽车的美观度，并提升汽车的档次，广泛应用在中高档汽车上。
现有技术中，亮饰条一般是通过后安装或粘接的方式集成在玻璃包边上。为了最大程度的吸引消费者，汽车厂商提出了各种亮饰条造型，其中就包含了将两根亮饰条后安装到玻璃包边上这种造型方案，两根亮饰条相邻端头的常见处理方式有：相邻端头并排排布；相邻端头上下重叠。目前的后安装完亮饰条的包边总成产品，会被安装到车身上，下底边亮饰条的外侧和车身钣金之间存在一个匹配关系。
现有技术中，为了追求视觉效果，通常需要亮饰条和亮饰条之间、亮饰条和车身钣金之间的缝隙尽可能小。但是，通常需要在两根亮饰条之间、以及亮饰条和车身钣金之间设置包边软胶，通过包边软胶来防止汽车行驶过程中亮饰条和亮饰条、亮饰条与车身钣金发生碰撞产生异响，但是由于软胶注塑工艺限制，无法将软胶厚度做到特别薄(厚度小于0.8mm)，对于视觉效果而言，由于软胶厚度偏厚导致的缝隙是汽车厂商所不希望的。
EPDM发泡材料可在亮饰条和亮饰条之间、亮饰条和车身钣金之间起缓冲作用，但是这种材料在玻璃包边总成产品上的应用存在局限性：1、这种材料与包边软胶材料外观存在明显差异，而亮饰条和亮饰条之间、亮饰条和车身钣金之间的缝隙均为外观可见的，因此，若直接将EPDM发泡材料应用于上述缝隙中，消费者能明显察觉到EPDM发泡材料与其他外观可见区域的包边软胶之间存在外观差异；2、EPDM发泡材料和包边软胶材料常见的结合方式是通过双面胶粘接，由于这种方式存在一定的操作复杂性，因此无法在亮饰条和亮饰条之间、亮饰条和车身钣金之间等精细度要求较高的区域运用。
发明内容
为了解决上述问题，本发明的目的在于提供一种亮条包边总成产品及其与外部部件 的连接方法。该亮条包边总成产品在与外部部件相接时产生的缝隙宽度在0.8mm以下，并且该总成产品与汽车车身或亮饰条之间的连接处外观平整统一、无明显差异。
为了达到上述目的，本发明提供了一种亮条包边总成产品，其中，所述亮条包边总成产品包括条形主体和包边软胶，所述包边软胶设于所述条形主体的端部、用于实现条形主体与外部部件之间的贴合，所述包边软胶的内部含有发泡区域。
相比于现有技术中借助独立的包边软胶连接亮饰条等条形主体与汽车车身的连接部件(如包边材料、亮饰条等)，本发明通过预先在条形主体用于连接的区域注塑可压缩变形的包边软胶材料，可以有效降低条形主体与外部连接部件之间的缝隙宽度，同时保证二者之间连接牢固而精准。
本发明提供的上述亮条是在制造过程中不预先与特定对象连接，而是在整体制造完成后、应用时才与特定对象贴合的后装亮条。
在本发明的具体实施方案中，所述包边软胶的内部含有发泡区域、发泡区域中均匀分布有发泡孔，当两条包边总成产品与外部部件连接时，在外部挤压力的作用下，发泡孔内的空气被外力挤压排出，包边软胶材料的整体占用体积变小，表现为包边软胶各部分同时发生变形，变形的包边软胶可以充分填充条形主体与外部部件连接处的缝隙，减小残留缝隙宽度。在一些具体实施方案中，当包边软胶处于自由状态，所述包边软胶内部的发泡区域的发泡密度为10-400kg/m3，例如10-200kg/m3，该范围的发泡密度可以使包边软胶具有足够的挤压变形能力。
在本发明的具体实施方案中，所述包边软胶的内部设有发泡区域、而外表面光滑无泡孔，以保证包边软胶在具有受力变形能力和避免本发明的条形主体与所连接的外部部件(例如汽车的亮饰条、汽车车身的包边软胶)之间的外观差异。例如，当外部部件为汽车玻璃的包边软胶材料时，本发明的上述包边软胶表面光滑无泡孔且与该包边软胶材质相同，二者外观无差别。此外，本发明的亮条包边总成产品与外部部件之间可以紧密贴合，且连接位置精细准确。
所述包边软胶的材质可以是TPE类软胶材料、PVC类软胶材料、PU类软胶材料等，这些材质的材料能够起到缓冲作用，且表面光滑无泡孔。

在本发明的具体实施方案中，所述亮条包边总成产品与外部部件的连接方式较为灵活，可以是并排连接、也可以是错位重叠连接。具体地，亮条包边总成产品与外部部件的连接方式可以包括弯折对接(如图1、图2)、斜切对接(图3、图6)、端部对接(图4)、部分重叠(图5)等。
本发明的有益效果在于：本发明提供的亮条包边总成产品与汽车车身、汽车亮饰条等外部部件连接产生的缝隙宽度可以达到0.8mm以下，同时可以保证连接处外观平整 统一、无明显差异。
