Description

Seat beam assembly, floor assembly and vehicle Technical Field The present disclosure relates to the field of vehicle accessories, and more particularly to a seat cross beam assembly, a floor assembly, and a vehicle. Background The seat beam assembly of the vehicle is used as a key bearing part of a vehicle body floor, the performance requirements of seat fixing strength, collision force transmission and the like are required to be met, and the conventional structural design of the seat beam assembly can bear static loads of 5-8 kN and impact acceleration of more than 15 g. Currently, seat beam assemblies include a beam body and a seat mounting assembly, wherein the beam body is typically a split component that is mounted on both sides of a center tunnel reinforcement plate using a segmented weld. However, with the above structure, the transverse support of the vehicle body of the beam body is weaker, so that when the vehicle bears 25% of small offset collision and side collision impact of the vehicle body, the transverse component force generated by the collision causes larger transverse local stress of the vehicle body floor area, and the seat beam assembly is easy to bend and deform, so that the seat is deformed, and the safety of passengers is influenced. Disclosure of Invention The present disclosure provides a seat cross beam assembly, a floor assembly, and a vehicle, capable of solving technical problems existing in the related art. The technical scheme of the seat beam assembly, the floor assembly and the vehicle is as follows: In a first aspect, the present disclosure provides a seat beam assembly comprising a beam body, a first seat mount and a second seat mount; The beam body is provided with a strip-shaped structure and is an integrally formed part, and is used for being mounted at the rear section of the middle channel reinforcing plate of the floor assembly; The first seat mounting assembly and the second seat mounting assembly are mounted to the same side of the beam body. In one possible implementation manner, the beam body has a first protruding structure, a second protruding structure and a third protruding structure which are distributed at intervals along the length direction; The first raised structures and the third raised structures are symmetrical about the second raised structures.

The technical scheme provided by the disclosure at least comprises the following beneficial effects: The present disclosure provides a beam assembly in which the beam body is an integrally formed part and is manufactured from a single block of hot formed boron alloy steel sheet, through rapid stamping after high temperature heating, and quench strengthening. On the one hand, the beam body has high self strength, and on the other hand, when the vehicle has 25% small offset collision and vehicle body side collision impact, the beam body is an integrally formed part, so that the part of the beam body 1 at the non-collision side can share the transverse component force generated by the part of collision, and the bending deformation amount of the part of the beam body 1 at the collision side is reduced. On the other hand, compared with the cold stamping process, the beam body 1 manufactured piece formed by hot forming is small in overall rebound deformation, and the welding matching chain among t
