The utility model relates to a kind of B-column-free vehicle body structure, including vehicle body and double-leaf car door, double-leaf car door includes front door and rear door;Front door includes first door outer plate, first door inner plate and first reinforcing part, first door outer plate and first door inner plate are connected and form first door cavity;First reinforcing part is set in first door cavity, and first reinforcing cavity is formed from the top of the rear end of front door and extends to the bottom of the rear end of front door;Rear door includes second door outer plate, second door inner plate and second reinforcing part, second door outer plate and second door inner plate are connected and form second door cavity;Second reinforcing part is set in second door cavity, and second reinforcing cavity is formed from the top of the front end of rear door and extends to the bottom of the front end of rear door.The utility model also proposes a kind of vehicle.The utility model can improve the rigidity and sealing performance of B-column-free vehicle body structure, help to improve the side impact performance of vehicle.

This invention relates to the field of automotive technology, specifically disclosing a side door ring roller forming component, a hollow cylindrical structure with a triangular cross-section, comprising a front section, an arc section, and a rear section. The front section is fixedly inserted into the A-pillar, and the rear section passes through the B-pillar and is fixedly inserted into the C-pillar. The arc section is located between the A-pillar and the B-pillar, with one end inserted into the B-pillar. A side door ring includes a side door ring roller forming component, an A-pillar, a B-pillar, and an inner door ring panel. The B-pillar includes an inner B-pillar panel and an outer B-pillar panel, both of which are double-layered. The inner layer of the outer B-pillar panel is completely located between the inner and outer B-pillar panels. The outer layer of the outer B-pillar panel is T-shaped, and a V-shaped section is provided at the top of the outer B-pillar panel. The V-shaped section forms a clearance area with the inner door ring panel, and the inner layer of the outer B-pillar panel extends to the root of the V-shaped section. This solution addresses the problem of reduced side-impact performance and compromised overall vehicle safety after the removal of the central roof beam in current automobiles.
