The invention discloses a light-weight automobile back door structure, and aims to overcome the defects that back doors of many existing dump trucks are heavy, the strength cannot meet the design requirement, and the impact resistance is poor. The automobile door comprises an automobile door frame, the two sides of the automobile door frame are connected with an inner plate and an outer plate respectively, the outer plate is provided with a plurality of die-casting grooves protruding towards the direction of the inner plate, the die-casting grooves are connected with the inner plate, and the inner plate and the outer plate are both made of glass fiber composite materials. The inner plate and the outer plate are both made of glass fiber composite materials, and are light in weight, good in strength and high in impact resistance. The automobile door frame is installed between the inner plate and the outer plate, the structural strength of the whole back door is guaranteed, the protruding die-casting groove in the outer plate is connected with the inner plate, the inner plate and the outer plate are connected to form a whole, axial stress points between the inner plate and the outer plate are increased, and the strength of the whole back door is effectively improved. The light-weight automobile back door structure is light in weight, capable of meeting the light-weight design requirement, good in strength, high in impact resistance and capable of meeting the design requirement.
本发明公开了一种轻量化汽车后背门结构,旨在解决现在很多自卸车的后背门重量大,强度达不到设计要求,抗冲击性能不佳的不足。该发明包括车门框,车门框两侧分别连接内板和外板,外板上设置若干向内板方向凸出的压铸槽,压铸槽与内板连接,内板和外板均为玻璃纤维复合材质。内板和外板均为玻璃纤维复合材质,重量轻,强度好,抗冲击能力强。内板和外板之间安装车门框,保证了整个后背门的结构强度,外板上凸出的压铸槽与内板连接,使内板和外板连接后完全成一个整体,增加了内板和外板之间轴向受力点,有效增加了整个后背门的强度。这种轻量化汽车后背门结构的重量轻,满足轻量化设计要求,而且强度好,抗冲击能力强,满足设计要求。
