The invention discloses a back door structure for a cross-border vehicle and a manufacturing method of the back door structure, the back door structure made of a metal plate is formed in the mode that a metal plate outer plate and a metal plate inner plate are divided in advance and connected and formed in the later period, and the production cost and the later maintenance cost are reduced. The metal plate outer plate is divided into an outer plate upper plate, an outer plate middle plate and an outer plate lower plate according to preset parameters, the metal plate inner plate is divided into an inner plate main plate and an inner plate frame according to preset parameters, all the parts meet the modeling requirements of all the parts, and then the parts are assembled together in the later period in the modes of gluing, edge covering, welding and the like. Therefore, the streamlined sheet metal back door with large inclination and large size is formed. The price of the metal plate is lower than that of resin, so that the production cost is reduced. If rear-end collision occurs, the metal plate can be locally maintained according to needs, the whole back door does not need to be replaced, and the later maintenance cost is reduced.
本发明公开了一种用于跨界车的后背门结构及其制造方法,其采用将钣金外板和钣金内板预先分割,后期连接成型的方式形成由钣金制成的后背门结构,降低了生产成本和后期维修成本。钣金外板根据预先设定参数分割为外板上板、外板中板、外板下板,钣金内板根据预先设定参数分割为内板主板和内板边框,各零部件满足各处的造型需求,后期再通过胶粘、包边、焊接等方式组装在一起,形成流线型、斜度大、尺寸大的钣金后背门。钣金的价格低于树脂价格,降低了生产成本。如发生追尾,根据需要可局部维修钣金,无需整体更换后背门整体,降低了后期维修成本。
