Connecting structure and vehicle

The utility model relates to a connecting structure and a vehicle. The connecting structure comprises a main frame, an auxiliary frame and a connecting piece. The connecting piece is fixedly connected with the auxiliary frame and fixed to the main frame in a spot welding mode. According to the connecting structure, the connecting piece and the main frame are fixedly connected through spot welding, due to the fact that the heating time is very short, the connecting piece and the main frame hardly deform, that is, the out-of-tolerance between the connecting piece and the main frame is small, and the auxiliary frame can be conveniently assembled through a fastener. Meanwhile, the connecting piece can have high-standard perpendicularity, so that the included angle between the connecting piece and the main frame is reduced, the mounting torque of the fastening piece is improved, and the risks of loosening and abnormal sound of the auxiliary frame are avoided. 本公开是关于一种连接结构和车辆。连接结构包括主车架、副车架和连接件。连接件与副车架固定连接，且与主车架点焊固定
