Claims (11)

A front side member extending along the longitudinal direction of the vehicle and having a cavity limited thereto; and A vehicle front side member assembly comprising a main reinforcing member including a bent portion, mounted in the cavity of the front side member.
In claim 1, The above front side member has a groove, and the groove faces the bent portion of the main reinforcing member, forming a vehicle front side member assembly.
In claim 1, A vehicle front side member assembly further comprising an auxiliary reinforcing member mounted on a bent portion of the main reinforcing member.
In claim 1, The bent portion of the above main reinforcing member is a vehicle front side member assembly having a V-shape.
In claim 4, The above main reinforcing member includes a front inclined wall and a rear inclined wall facing the front inclined wall, and The above-mentioned front inclined wall and the above-mentioned rear inclined wall form a V-shape, forming a vehicle front side member assembly.
In claim 5, The vehicle front side member assembly, wherein the front inclined wall and the rear inclined wall have a symmetrical shape with respect to the groove of the front side member.
In claim 5, It further includes a front flat wall extending from the front inclined wall toward the front end of the front side member, and a rear flat wall extending from the rear inclined wall toward the rear end of the front side member. The above front flat wall and the above rear flat wall are a vehicle front side member assembly fixed to the above front side member.
In claim 1, A vehicle front side member assembly further comprising front mounting hardware provided on the front portion of the front side member and rear mounting hardware provided on the rear portion of the front side member.
In claim 8, A vehicle front side member assembly further comprising a front bulkhead aligned with the front mounting hardware and a rear bulkhead aligned with the rear mounting hardware.

Description

Vehicle Side Sill Assembly The present invention relates to a vehicle front side member assembly, and more specifically, to a vehicle front side member assembly capable of minimizing passenger injury by inducing a certain deformation during a collision of the vehicle. Recently, various vehicles such as MPVs (Multi-Purpose Vehicles) and electric vehicles are implementing a cap-forward design to ensure sufficient interior space and improve performance. To implement a cab-forward design, the front overhang can be configured to be relatively short by moving the cowl panel forward compared to the design of existing vehicles. Furthermore, to implement a cab-forward design, the windshield glass must be configured to move forward compared to existing vehicle designs to align with the position of the cowl panel, and it is necessary to satisfy windshield fixability regulations in the domestic and North American markets. Windshield fixability regulations are designed to prevent windshield breakage in order to ensure airbag deployment support during a collision; thus, development must be directed toward reducing body deformation (dynamic deformation) during a collision. Reducing body deformation allows the vehicle to absorb relatively less collision energy, and the remaining energy may be transferred to the passenger compartment. Accordingly, it is necessary to reduce body deformation precisely to the extent that the windshield does not break. However, existing front side members had a disadvantage in that it was difficult to deform the front side member consistently while satisfying windshield fixation regulations, as there was variation in the amount of deformation of the vehicle body due to collisions. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs.
