The invention discloses a split type plastic back door assembly structure which comprises a spoiler, a back door lower outer plate and a back door inner plate, the back door lower outer plate is arranged below the spoiler, polyurethane structural adhesive is arranged in the back door inner plate, a metal plate for fixing the position of the spoiler is arranged in the back door inner plate, and the spoiler is arranged in the metal plate. A wire harness is arranged between the spoiler and the back door inner plate, corrosion-resistant layers are arranged on the two sides of the back door inner plate, first reinforcing plates are arranged on the outer walls of the corrosion-resistant layers, reinforcing layers are arranged on the outer walls of the first reinforcing plates through heat-resistant binders, reinforcing ribs are arranged in the reinforcing layers, and the reinforcing ribs are arranged on the outer walls of the first reinforcing plates through heat-resistant binders. According to the device, the rubber blocks at the fixing blocks are extruded through the protruding blocks, meanwhile, the annular elastic plates are extruded to be tightened, then the anti-compression effect is achieved under the elastic left and right sides of the rubber blocks and the annular elastic plates, and the situation that the inner plate of the back door is damaged due to the fact that impact pressure is too high is avoided.
本发明公开了一种分体式塑料后背门总成结构,包括扰流板、后背门下外板和后背门内板,所述扰流板的下方设置有后背门下外板,所述后背门内板的内部设置有聚氨酯结构胶,所述后背门内板内部设置有固定所述扰流板位置的钣金,所述扰流板和后背门内板之间设置有线束,所述后背门内板的两侧设置有耐腐蚀层,且耐腐蚀层的外壁设置有第一加强板,所述第一加强板的外壁通过耐热粘结剂设置有加强层,且加强层的内部设置有加强筋,所述加强层的外壁设置有第二加强板,该装置通过凸块对固定块处橡胶块进行挤压,同时环形弹性板受到挤压发生缩紧,进而在橡胶块和环形弹性板弹性左右下具有抗压效果,避免冲击压力过高而对后背门内板处出现损坏。
