Abstract

The invention provides a sectional type B column inner plate structure. The structural problem that in a traditional structural design, spot welding cannot be achieved in the welding process of an integral type B column inner plate and a threshold inner plate can be solved. The sectional type B column inner plate structure comprises a B column inner plate body, the bottom of the B column inner plate body is an overlap edge used for being connected with the threshold inner plate, a safety belt emergency locking retractor via hole is formed in the position, close to the overlap edge, of the lower end of the B column inner plate body, the critical point lies in the fact that the B column inner plate body is disconnected on the two sides of the safety belt emergency locking retractor via holeto form a sectional structure including a B column inner plate body upper section and a B column inner plate body lower section, and the B column inner plate body upper section and the B column innerplate body lower section are connected in a spot-welded mode through an overlap edge structure.

Description

technical field [0001] The invention relates to the technical field of automobile body structures, in particular to a segmented B-pillar inner panel structure and a welding method thereof. Background technique [0002] At present, the inner panel of the B-pillar of the automobile is usually a whole, and the side wall assembly is formed by welding with other parts. In the process of forming the skeleton of the side panel assembly and the lower body, the integrated B-pillar inner panel and the door sill inner panel cannot be spot-welded, and the joint structure can only be achieved through CO2 welding. CO2 welding has certain welding quality problems, and while increasing the production cycle, it leads to an increase in the manufacturing cost of the bicycle. The existing integral B-pillar inner panel body and the sill inner panel overlapping structure are as follows: figure 1 Shown at o. Contents of the invention [0003] The purpose of the present invention is to propose...
