Automatic side door structure

A door structure system for a vehicle includes an inner panel, an outer panel, and an outer strap reinforcement member. The outer band reinforcing member extends in a front-rear direction of the door structure. The outer band reinforcement member creates a lap joint with the crimped flange portion of the inner panel. The outer strap reinforcement member includes a touch feature extending toward the inner panel and in contact with a bearing surface of the inner panel that is stepped down relative to the hem flange portion. Both the lap joint and the touch feature help increase the stiffness of the upper frame of the door structure and improve the sealing performance between the door structure and the vehicle body structure. 一种用于车辆的门结构系统，该门结构系统包括内面板、外面板和外带加强构件。外带加强构件沿门结构的前后方向延伸。外带加强构件与内面板的卷边凸缘部分产生搭接接头。外带加强构件包括朝向内面板延伸并且与内面板的相对于卷边凸缘部分台阶式下降的支承表面接触的碰触特征。搭接接头和碰触特征两者均有助于增加门结构的上部框架刚度并且改善门结构与车辆车身结构之间的密封性能。
