The invention discloses an integrally-cast back door structure and a vehicle. The technical problems that in the prior art, the size chain is long, and the production rejection rate is high are solved. The integrally-cast back door structure comprises a back door body and a reinforcing piece. The back door body is integrally cast and comprises an inner plate and an outer plate, and a cavity is formed between the inner plate and the outer plate. The reinforcing piece is arranged in the cavity and connected with the inner plate and the outer plate. Compared with an existing welding mode, the integrally-cast back door structure has the advantages that the overall precision of the integrally-cast back door structure is high, the length of an installation size chain of accessories such as a hinge, a supporting rod and a lock is short, and assembly errors caused by too many parts can be reduced. According to the integrally-cast back door structure, integration of the inner plate and the outer plate is achieved through the integrally-cast technology, an inner plate and outer plate combining piece of a traditional back door is eliminated, the length of a size chain is reduced, the rejection rate is reduced, meanwhile, the overall strength and weight distribution are optimized through the reinforcing piece, and the overall performance and the light weight level of the back door are improved.

    本申请公开了一种一体铸造背门结构及车辆,解决现有技术尺寸链长且生产废品率高的技术问题。一体铸造背门结构包括背门本体和加强件。背门本体采用一体铸造而成,背门本体包括内板和外板,内板和外板之间形成型腔。加强件设置于型腔内且与内板和外板均连接。通过一体成型铸造的内板与外板和现有的通过焊接的方式相比,一体铸造背门结构整体精度较高,铰链、撑杆、锁等附件安装尺寸链长度短,可减少因零件过多所带来的装配误差。本申请公开的一体铸造背门结构通过一体铸造技术实现内板和外板的集成,消除了传统背门的内板和外板合件,减少了尺寸链长度,降低了废品率,同时利用加强件优化整体强度和重量分布,提高背门的整体性能和轻量化水平。
