Automobile B column upper connector structure and automobile

Abstract

The invention discloses an automobile B column upper connector structure and an automobile. The automobile B column upper connector structure comprises a B column structure, an A column structure and a BC column connecting structure, the B column structure comprises a B column inner plate and a B column outer plate, a lap joint cavity is formed between the B column inner plate and the upper end of the B column outer plate, the A column structure comprises an A column upper inner plate and an A column upper reinforcing plate, the A column upper inner plate and / or the A column upper reinforcing plate are / is partially located in the lap joint cavity, in the BC column connecting structure, the BC column connecting inner plate and / or the sliding door upper guide rail mounting plate and / or the sliding door upper guide rail mounting reinforcing plate are / is partially located in the lap joint cavity, the cavity structure is good in strength and rigidity, the lap joint rigidity of the B column upper connector is improved, the whole sliding door can be effectively supported, and the sliding door mounting frame is prevented from deforming and generating abnormal sound due to insufficient rigidity, can bear load to the maximum extent in side collision, and is prevented from breaking and losing efficacy in the collision.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile B-pillar upper joint structure and an automobile. Background technique [0002] The B-pillar is an important supporting frame of the car, which connects the door sill, roof, A-pillar and C-pillar and other areas, and has a very important impact on the vehicle's side collision safety, vehicle strength, stiffness and NVH performance. . Except for some convertible sports cars, almost all cars will be equipped with B-pillars, and the front side door locks and rear side door hinges are set on the B-pillars, which are also used as the installation position of the seat belt and realize the height adjustment function of the seat belt. [0003] At present, the sunroof of a car is a very common configuration. The sunroof, especially the large sunroof / panoramic sunroof, has a great impact on the side collision and bending and torsional rigidity of the car. Among them, th...

Problems solved by technology

Among them, the structure of the joint on the B-pillar connecting the top cover is particularly important, especially for models with sliding doors, the design and overlapping position of the joint on the B-pillar are particularly particular, and directly affect the stiffness and strength of the joint and the side impact performance. The joints on the B-pillar in the technology still need to be optimized
