汽车车身流水槽的主要功能在于将车身雨水沿着导水槽排到车外,防止水流进入汽车车体内部和车身钣金结构内部,提供内部舒适乘坐空间和防止车身钣金在雨水的作用下过早锈蚀,因此合理的结构设计非常重要。本文主要讲述两厢汽车车身后柱流水槽结构设计,以及防止雨水进入车体的一些结构及工艺方法。车身后柱流水槽一般由后流水槽上段板,后组合灯安装板焊接形成,顶部与顶盖焊接,侧面与侧围外板焊接,下部与后围板焊接,其有一定的截面形状,形成一个从顶盖沿后柱到车身底部的导水槽,在结构功能方面要求能将车身顶部的水沿该导水槽向下排出车体,保证雨水不从顶部,线束过孔及尾灯安装孔等处进入车体内部。
The main function of the car body flow groove is to drain the rainwater along the guide tank to the outside of the car, prevent the flow of water into the interior of the car body and the body structure of the body, and provide the internal comfortable space and prevent the early rust of the body sheet metal under the action of the rain. Therefore, the rational structural design is very important. This article mainly describes the structure design of the rear column water trough of the hatchback car body, and some structures and process methods to prevent the rain from entering the car body. The flow trough of the rear body column is usually welded by the upper plate of the back flow trough and the rear assembly lamp. The top is welded with the top cover, the side and the side outer plate are welded and the lower and the rear enclosing plates are welded. It has a certain section shape, forming a water guide trough from the back column to the bottom of the body, and the structure function requires the water at the top of the body. The car body is discharged down along the guide slot to ensure that the rainwater does not enter the inside o
