B-column inner plate and vehicle with same

Abstract

The invention discloses a B-column inner plate and a vehicle with the same. The B-column inner plate comprises an inner plate body and a reinforcing plate; a retractor mounting hole is formed in the inner plate body; the reinforcing plate is arranged on the lower side of the retractor mounting hole and is welded and fixed with the inner plate body; flanging parts are arranged on the inner circumferential edge of the retractor mounting hole, the a receding opening is formed in the flanging part on the lower side edge of the retractor mounting hole, and the two ends of the receding opening are located between the front end welding spot and the rear end welding spot of the reinforcing plate respectively. Therefore, the B-column inner plate has higher structural strength, can effectively resist side impact, improves the use safety, and meets the side impact requirement of a deformable movable barrier side impact test related to the side impact performance in the C-NCAP.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a B-pillar inner panel and a vehicle having the same. Background technique [0002] In related technologies, with the development of the vehicle industry, the safety of vehicles has been paid more and more attention by manufacturers and consumers. As the main support structure of the vehicle body frame, the side wall of the vehicle is tested in the side impact test of the deformable movable barrier in C-NCAP (Chinese name: China-New Car Assessment Program English name: China-New Car Assessment Program). Safety performance presents increasingly stringent requirements. [0003] However, the retractors used by the front row occupants of the vehicle are generally arranged in the cavity of the B-pillar, and are usually installed on the inner panel of the B-pillar. The retractor is generally assembled in the final assembly process, and a retractor mounting hole needs to be designed ...

AI Technical Summary

Problems solved by technology

[0004] The mounting hole of the retractor is located at the impact position in the side impact test of the deformable mobile barrier. If the structural design of the mounting hole of the retractor is poor, the B-pillar may be damaged when the retractor is installed in the side impact test or when the vehicle has a side impact. There is a large deformation in the hole area, which even leads to the breakage of the B-pillar. Not only is the existing B-pillar difficult to meet the C-NCAP test, but it is also less safe to use
