The limitation of welding procedure error is effectively eliminated, and ensure that the integral strength of B column inner panel, improves lightweight performance.
To achieve the above object, the utility model provides following scheme: the utility model is provided in a kind of segmented B column
Plate, including B column inner panel upper section, B column inner panel lower section and connecting plate, the bottom of the B column inner panel upper section and the B column inner panel lower section
Connection, the connecting plate are set to the junction of the B column inner panel upper section and B column inner panel lower section.
Preferably, the B column inner panel upper section, the B column inner panel lower section and the connecting plate are all made of aluminum alloy materials
It is made.
Preferably, the bottom of the B column inner panel upper section and the connecting plate pass through spot-welded.
Preferably, the B column inner panel lower section is welded respectively with the bottom of the B column inner panel upper section and the connecting plate
It connects.
Preferably, for connecting with floor skirt beam in lower body, the B column inner panel upper section is used for the B column inner panel lower section
It is connect with covering for roofs crossbeam.
Preferably, the B column inner panel lower section passes through MIG with floor skirt beam in lower body and welds.
Preferably, the body thickness of the segmented B column inner panel is 1.8mm.
The utility model achieves following technical effect compared with the existing technology:
1, traditional monoblock type B column inner panel is decomposed into the B column inner panel upper section and B column inner panel of split settings by the utility model
Lower section effectively eliminates the limitation of welding procedure error when floor skirt beam is extrusion in lower body；
2, it is attached between B column inner panel upper section and B column inner panel lower section by connecting plate, compensates for B column inner panel because of segmentation
Caused strength reduction reinforces intensity；
3, B column inner panel is made of aluminum alloy materials, meets B column inner panel material requirements, and compensate for cold-rolled steel sheet
Disadvantage, guarantees the craftsmanship of sheet metal component, while increasing the crashworthiness of vehicle body；And material is light, realizes zero, automobile
The lightweight of part；
4, by the combination of a variety of welding manners, it ensure that the intensity of B column inner panel entirety.
