The invention relates to a hatchback type back door lock reinforcing structure and a back door. The hatchback type back door lock reinforcing structure comprises a back door lock reinforcing piece assembly composed of a back door lock reinforcing piece and a back door outer plate reinforcing piece. The back door lock reinforcer is fixedly connected to the back door outer plate reinforcer; the back door lock reinforcer is a sheet metal part with the middle protruding, a back door lock via hole is formed in the lower portion of the back door lock reinforcer, an emergency opening handle via hole is formed in the rear portion of the back door lock reinforcer, and a turned-over edge is arranged on the edge of the front face of the back door lock reinforcer. The back door outer plate reinforcer is a sheet metal part with a concave middle part, is provided with a bottom surface and two side walls and is in a groove shape, an avoiding window for the back door lock assembly is arranged in the middle of the bottom surface of the back door outer plate reinforcer, and planes are respectively arranged close to the left side and the right side of the avoiding window; the front face of the back door lock reinforcer corresponds to the avoiding window, and the flanging of the front edge of the back door lock reinforcer is fixedly connected with the planes of the left side and the right side of the avoiding window. The problem that a back door inner plate of a hatchback type back door vehicle is difficult to form can be solved, and the concave resistance, the torsional rigidity and the modal performance of a back door outer plate can be improved.
本发明涉及一种掀背式背门锁加强结构及背门，包括由背门锁加强件和背门外板加强件构成的背门锁加强件总成；背门锁加强件固定连接在背门外板加强件上；背门锁加强件为中部凸起的钣金件，在背门锁加强件的下面设有一个背门锁过孔、后面设有一个紧急开启手柄过孔、前面边缘设有翻边；背门外板加强件为中部下凹的钣金件，其具有一个底面和两个侧壁，呈“凹槽”形，在背门外板加强件的底面中部设有用于背门锁总成的避让窗口，在靠近避让窗口左右两边分别设有平面；背门锁加强件的前面与避让窗口对应，其前面边缘的翻边与避让窗口左右两边的平面固定连接。其能够解决掀背式背门车型背门内板成型困难的问题，还能够提升背门外板的抗凹性、扭转刚度、模态性能。
