Vehicle body pillar B lower reinforcing assembly

Abstract

The invention discloses a vehicle body pillar B lower reinforcing assembly. The vehicle body pillar B lower reinforcing assembly comprises a pillar B body and a threshold body, the pillar B body comprises a pillar B inner plate and a pillar B reinforcing plate, the pillar B reinforcing plate is longitudinally extended and fixed in front of the pillar B inner plate, the threshold body comprises a threshold outer plate and a threshold inner plate, the lower end of the pillar B inner plate is perpendicularly extended and fixed between the threshold outer plate and the threshold inner plate, the lower end of the pillar B reinforcing plate is perpendicularly extended and fixed to the middle lower part of the front side of the threshold outer plate, a threshold outer reinforcing plate is fixedlyarranged between the rear side of the threshold outer plate and the front side of the pillar B inner plate, a side wall outer plate of a vehicle body is fixed in front of the pillar B reinforcing plate and in front of the threshold outer plate, a seat cross beam and a front floor body are horizontally arranged on the upper side and the lower side of the rear side of the threshold inner plate respectively, and the seat cross beam and the front floor body are arranged in parallel. According to the vehicle body pillar B lower reinforcing assembly, the pillar B body can bear enough impact force when undergoing the side surface collision, and the pillar B body has enough strength to ensure that the situations that due to the fact that the threshold turnover occurs, the pillar B immersion amount is excessively large, and then the side surface deformation is caused during collision can be avoided.

Description

technical field [0001] The invention relates to a vehicle body B-pillar reinforcement assembly, in particular to a vehicle body B-pillar lower reinforcement assembly for strengthening the connection strength of the lower part of the B-pillar. Background technique [0002] The B-pillar structure of the body plays a key role in the torsional rigidity and collision safety of the body, especially the safety of side collisions. In the torsional condition of the body, the B-pillar structure affects the deformation of the body. The collision plays a role in reasonably absorbing the collision energy and protecting the safety of the occupants. The traditional B-pillar structure has the following problems: [0003] 1. If Figure 1 to Figure 4 As shown, the lower end of the traditional B-pillar structure includes B-pillar inner panel 1', sill outer panel 2', sill inner panel 3', side wall outer panel 4', seat beam 5', front floor body 6' and B-pillar reinforcement 7', the side wall o...

Problems solved by technology

[0005] The present invention is completed in order to solve the deficiencies in the prior art. The purpose of the present invention is to provide a B-pillar body that can withstand sufficient impact force when it is subjected to a side impact, and has sufficient strength to ensure that the threshold will not be sent when the collision occurs. Body B-pillar lower reinforcement assembly that deforms sideways due to excessive immersion in the B-pillar due to overturning
