Abstract

The invention provides a welding structure and a welding method for a cavity part of a vehicle body outer plate. The welding structure is characterized in that a U-shaped support part matched with an inner surface of the cavity part of the vehicle body outer plate in shape is fixedly connected to a vehicle body outer plate connecting member and is bonded with the inner surface of the cavity part of the vehicle body outer plate. The U-shaped support part is for supporting the cavity part of the vehicle body outer plate is additionally arranged before the vehicle body outer plate and the vehicle body outer plate connecting member are welded, so that the defect that the local strength of a cavity structure of the vehicle body outer plate is insufficient is made up; the energy absorption buffering capability of a vehicle body under the condition of side crash is improved to a certain degree while the action of the cavity structure is ensured; and in addition, the reformation for a production line is little, and thus the cost is low.

Description

technical field [0001] The invention relates to the technical field of automobile body manufacturing, and specifically designs a welding structure and a welding method for a cavity part of an outer panel of a vehicle body. Background technique [0002] In the early design process of the car body, in order to enhance the rigidity, deflection, and energy absorption capacity of a certain local structure, prevent the structural deformation of this area and affect the performance of the whole vehicle, it will be designed as a cavity structure to meet the body strength and collision need. However, considering the shape design and space layout of the vehicle, in this cavity structure, the hollow size is often large (generally between 300mm-500mm), resulting in the local unidirectional strength of the stamping parts on the outer surface forming the cavity. Guaranteed (especially when the outer surface is thin and has a large area, such as the thickness of the side wall outer panel...
