The invention relates to an upper sealing structure of a sliding door. The upper sealing structure mainly comprises an upper sealing strip, a vehicle body and a vehicle door, the upper sealing strip is clamped and sealed with a vehicle body and is sealed with a vehicle door; the upper sealing strip is composed of a sealing strip extrusion section, a vehicle front connecting corner and a vehicle rear connecting corner. The extrusion section of the sealing strip is clamped through the buckles, and the connecting corners are fixed through the buckles respectively and are adhered through the adhesive tape and the adhesive tape. According to the sliding door upper sealing structure, the upper sealing strip is installed on a vehicle body through the buckle, a small lip part of a sealing strip foam pipe and a vehicle body fillet are extruded to form primary sealing of the vehicle body side, a small protrusion at the bottom of the foam pipe and a vehicle body metal plate are extruded to form secondary sealing, and the skirt edge of the buckle deforms and is tightly attached to the vehicle body metal plate to form buckle water resistance; two seals on the vehicle door side are formed through extrusion deformation of the foam pipe and the large lip side of the upper sealing strip and the vehicle door metal plate; the sealing scheme is simple in structure and convenient to install, and has the cost advantage.
本发明涉及一种滑门上部密封结构,主要由上部密封条、车身和车门构成;所述上部密封条与车身卡接并密封,与车门密封;所述上部密封条由密封条挤出段、车前接角和车后接角组成;所述密封条挤出段用卡扣卡接,接角和接角分别采用卡扣和卡扣固定,辅以胶带和胶带粘接。本发明滑门上部密封结构,通过卡扣将上部密封条安装在车身上,密封条泡管的小唇部与车身圆角挤压形成车身侧一道密封,泡管底部小凸起与车身钣金挤压形成二道密封,卡扣自身的裙边变形与车身钣金紧密贴合构成卡扣防水;通过上部密封条的泡管和大唇边与车门钣金的挤压变形,形成车门侧的两道密封;本密封方案结构简单,安装方便,且有成本优势。
