In the fender apron upper member according to the embodiment of the present invention, in the upper member of the fender apron, a certain section rearward of the extruded beam is vertically separated to form an upper foaming end and a lower foaming end, And is fastened to the inner side surface and the outer side surface of the front pillar of the vehicle body, respectively.

Description

Fender Apron Upper Member {FENDER APRON UPPER MEMBER}

The present invention relates to a fender apron upper member, and more particularly, to a fender apron upper member that effectively disperses input collision energy during a small overlap collision to improve collision performance.

Generally, when a vehicle collides with another automobile or a fixed body, a collision load is absorbed, transmitted and dispersed to minimize the deformation of the passenger compartment, and at the same time, a front side member and a front filler And the fender apron upper member is connected between them.

In the prior art, since the fender apron upper member is joined to the front pillar in the form of a flange, the joined cross section between the front filler and the fender apron upper member is easily separated at the time of a small overlap collision of the vehicle, The structure is vulnerable to dispersion.

In addition, since the conventional fender apron upper member has a structure in which a plurality of single parts are combined to form a closed end face, manufacturing costs such as the investment cost of the mold increase, and the joint strength applied to the plurality of single parts is weak , There is a problem that the collision energy is transmitted only in one direction and is vulnerable to small overlap collision.

The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.

The embodiment of the present invention is a structure in which a rear part of the extruded beam is divided into upper and lower portions to form an upper foaming end and a lower foaming end and each of the upper foaming end and the lower foaming end is fastened to a front filler of a vehicle body, And absorbing the collision energy input at the time of collision and dispersing the collision energy through the upper forming unit and the lower forming unit, thereby improving the collision performance.

In one or more embodiments of the present invention, in the fender apron upper member, a rearward portion of the extruded beam is divided in the vertical direction to form an upper foaming end and a lower foaming end, The fender apron upper member fastened to the inner and outer sides of the front pillar of the fender apron can be provided.

The upper forming end and the lower forming end may be formed with a plurality of bolt holes, and may be bolted to the front pillar.

In addition, the extruded beam may have three closed end faces, and both sides of the closed end face of the center may be narrower in width than the closed end face.

Further, the extruded beam may be an aluminum material.

The embodiment of the present invention is characterized in that an impact energy input at the time of a small overlap collision is fixed by being fastened to the inner side surface and the outer side surface of the front pillar of the vehicle body through the upper forming end and the lower forming end separated in the vertical direction of the rear part of the extrusion beam, It is possible to improve the collision performance by absorption and dispersion.

Also, since the embodiment of the present invention is formed by one beam through extrusion molding, the number of parts is reduced, the cost is reduced, and the assembly is simple, thereby reducing the manufacturing process cost.

In addition, the effects obtainable or predicted by the embodiments of the present invention are directly or implicitly disclosed in the detailed description of the embodiments of the present invention. That is, various effects to be predicted according to the embodiment of the present invention will be disclosed in the detailed description to be described later.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be understood, however, that the drawings and the following detailed description are exemplary and explanatory of various embodiments for effectively illustrating the features of the present invention. Therefore, the present invention should not be limited to the following drawings and descriptions.

FIG. 1 is a perspective view of a fender apron upper member according to an embodiment of the present invention, FIG. 2 is a mounting perspective view of a fender apron upper member according to an embodiment of the present invention, FIG. 4 is a view showing an impact dispersion path of a fender apron upper member according to FIG.

Referring to FIGS. 1 and 2, a fender apron upper member 1 according to an embodiment of the present invention is formed of an extruded beam 1a formed through extrusion molding.

The extruded beam 1a has three closed end faces.

At this time, the closed end faces of the center of the three closed end faces of the extruded beam 1a are formed narrower than the closed end faces of both sides.

The extrusion beam 1a may be formed of an aluminum material.

The fender apron upper member 1 formed of the extruded beam 1a as described above is divided in the vertical direction to form the upper forming end 3 and the lower forming end 5.

The upper forming end 3 and the lower forming end 5 are formed to extend in a "Y " shape.

At this time, the upper forming end 3 and the lower forming end 5 are formed with a plurality of bolt holes 7, and the bolts B are fastened to the vehicle front filler through the bolt holes 7.

That is, the upper forming end 3 is fastened to the inner side surface of the vehicle body front pillar 10 by bolts B and the lower forming end 5 is fastened to the outer surface of the vehicle body front pillar 10 by bolts do.

Referring to FIG. 3, the fender apron upper member 1 configured as described above absorbs input impact energy at the time of a small overlap collision, and then disperses it through the upper forming end 3 and the lower forming end 5 To the vehicle body.

Hereinafter, a method of manufacturing the fender apron upper member 1 according to the embodiment of the present invention will be described.

4 is a process diagram illustrating a method of manufacturing a fender apron upper member according to an embodiment of the present invention.

Referring to Fig. 4 (A), an extruded beam 1a having three closed end faces is formed through extrusion molding.

At this time, the extrusion beam 1a may be an aluminum extrusion beam 1a made of an aluminum material.

Referring to FIG. 4 (B), a plurality of bolt holes 7 are formed in the width direction at one end of the extruded beam 1a.

At this time, the plurality of bolt holes 7 are formed through piercing molding.

Referring to FIG. 4 (C), the closed end face section of the extruded beam 1a is cut longitudinally from one end to a certain section.

Referring to FIG. 4 (D), an upper forming end 3 and a lower forming end 5 are formed at one end of the extruded beam 1a.

At this time, the upper forming end 3 and the lower forming end 5 are formed in a vertically downward direction on both sides of the extruded beam 1a.

Therefore, the fender apron upper member 1 according to the embodiment of the present invention is fastened to the inner side surface and the outer side surface of the vehicle body front pillar 10 through the upper forming end 3 and the lower forming end 5, By absorbing and dispersing the collision energy input at the time of the small overlap collision, the collision corresponding performance can be improved.

In addition, the fender apron upper member 1 according to the embodiment of the present invention is applied with an extruded beam 1a made of an aluminum material, which is lightweight and easy to assemble to the vehicle body, thereby simplifying the assembling process.
