Vehicle body assembly, vehicle provided with vehicle body assembly as well as doorsill beam reinforcing assembly of vehicle body assembly

Abstract

The invention discloses a vehicle body assembly, a vehicle provided with the vehicle body assembly and a doorsill beam reinforcing assembly of the vehicle body assembly. The vehicle body assembly comprises a doorsill side beam outer plate and a doorsill side beam inner plate as well as a doorsill beam reinforcing assembly, wherein the doorsill beam reinforcing assembly is arranged between the doorsill side beam outer plate and the doorsill side beam inner plate, and comprises a doorsill reinforcing beam, a doorsill side beam reinforcing bracket, and a limiting structure; the doorsill side beamreinforcing bracket is provided with a collapse structure; the limiting structure is connected to the doorsill reinforcing beam; and the limiting structure limits the doorsill beam reinforcing bracket from further collapsing while the collapse structure achieves predetermined collapse amount. According to the vehicle body assembly disclosed by the invention, the doorsill beam reinforcing assemblyhas relatively high structure strength and relatively high press and collapse resistance after being collapsed, ensures that Y-axis deformation amount of the doorsill is not too great, effectively reduces B column press and collapse intrusion amount, and ensures living space and safety of the driver and passengers.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a vehicle body assembly, a vehicle with the vehicle body assembly, and a door-sill beam reinforcement component of the vehicle body assembly. Background technique [0002] The structure of the sill beam has a great influence on the side impact performance of the vehicle body, and also greatly affects the safety of the occupants. The door sill beam of a general vehicle cannot transfer side impact energy to the seat beam and the floor well, which may easily lead to a large amount of B-pillar crush intrusion, too fast intrusion speed, and the deformation of the door sill along the Y direction is too large, which cannot guarantee the safety of the occupants. There is room for improvement. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present inventi...
