Description

technical field

[0001] The invention relates to the field of automobile assembly, in particular to a vehicle frame installation structure, a vehicle frame and a vehicle. Background technique

[0002] In the process of automobile body design and manufacturing, especially in the field of commercial vehicles, due to the shape and structure of the vehicle body, the tail beam baffle of the commercial vehicle frame and the lower section of the side column are overlapped to form a whole. The commonly used process method is Carbon dioxide gas shielded welding.

[0003] However, after carbon dioxide shielded welding, the strength of the connection cannot be measured simply, quickly and effectively on site. Contents of the invention

[0004] The main purpose of the present invention is to provide a vehicle frame installation structure, vehicle frame and automobile, aiming to solve the problem that the welding connection strength of the vehicle frame cannot be detected.
