## Background
CROSS-REFERENCE TO RELATED APPLICATION
The present application claims priority to Korean Patent Application No. 10-2010-0048210 filed in the Korean Intellectual Property Office on May 24, 2010, the entire contents of which is incorporated herein for all purposes by this reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a bumper beam assembly for a vehicle. More particularly, the present invention relates to a bumper beam assembly for a vehicle that may enhance assembly strength when assembling a bumper beam and a stay.
2. Description of Related Art
Generally, a bumper is a part of a vehicle designed to help it withstand impact of a collision and the bumpers are disposed forward and rearward of the vehicle to minimize deformation of the vehicle in collision.
As shown in FIG. 6, a bumper 100 includes a bumper beam unit 105 including a bumper beam 101 disposed along vehicle width direction at forward and rearward of a vehicle and a stay 103 interposed between the bumper beam 101 and a side member 111 of a vehicle body, an energy absorber 107 disposed front of the bumper beam 101 for absorbing impact and a bumper cover 109 covering the bumper beam 101 and the energy absorber 107.
The stay 103 is connected to a rear portion of the bumper beam 101 and then the conventional bumper beam unit 105 is assembled to the side member 111.
Recently the bumper beam 101 has been manufactured by aluminum material and made by extrusion molding for reducing weight replacing steel material corresponding trend light-weight vehicle, and also, the stay has been made of aluminum material and made by extrusion molding.
If the bumper beam 101 and the stay 103, which are made by aluminum extrusion molding, are assembled by laser welding, pore or crack may be generated in welding portion and thus generally those are assembled by mechanical assembling such as bolt engagement and so on.
However, if the bumper beam 101 and the stay 103 are assembled by mechanical assembling such as bolt, impact energy transferred from the bumper beam 101 may be concentrated on the bolt connecting portion in collision and thus assembling portion of the bumper beam 101 and the stay 103 may be easily deformed and impact energy dispersion and absorption may be deteriorated.
The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION
Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that the present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
An exemplary embodiment of the present invention will hereinafter be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a bumper beam assembly according to an exemplary embodiment of the present invention and FIG. 2 and FIG. 3 are frontward and rearward exploded perspective views showing a bumper beam assembly according to an exemplary embodiment of the present invention.
A bumper beam assembly for a vehicle according to an exemplary embodiment of the present invention includes a bumper beam 1 including a horizontal support plate 21, a front vertical support plate 22, rear vertical support plate 23 of which an insertion hole 7 is formed thereto and a partition 3 formed therewithin along the horizontal support plate 21 and a stay 5 inserted into the insertion hole 7.
The bumper beam 1 and the stay 5 may be made of aluminum material and made by extrusion molding.
A partial portion of the partition 3 where the insertion hole 7 is formed at rear side of the bumper beam 1 may be eliminated along forward and rearward direction.
The insertion hole 7 is correspondingly formed to periphery of the stay 7.
At one end of the stay 5, as shown in FIG. 4 and FIG. 5, a partition groove 9 is formed for the partition 3 to be inserted into therein.
In an exemplary embodiment of the present invention, the one end of the stay 5 may be engaged with the front vertical support plate 22.
A mounting hole 17 is formed to the horizontal support plate 21, an engage hole 15 is formed to the stay 5 corresponding to the position of the mounting hole 17 and the bumper beam 1 and the stay 5 are connected through the mounting hole 17 and the engage hole 15.
A nut 11 is connected to the engage hole 15 and a bolt 13 is connected to the nut 11 for the bumper beam 1 and the stay 5 to be connected.
A mounting bracket 25 is connected to the other end of the stay 5.
The nut 11 may be connected to an inside of the engage hole 15 by welding or the nut 11 may be a pop nut and connected to the engage hole 15.
As described above, the nut 11 is connected to the stay 5, and then, as shown in FIG. 5, the end of the stay 5 is inserted into the insertion hole 7 of the bumper beam 1 and simultaneously the partition 3 is inserted into the partition groove 9 and then the bolt 13 is engaged with the nut 11 within the stay 5 through the mounting hole 17 and the engage hole 15 and thus assembling is completed.
And thus, the bumper beam assembly for a vehicle according to the exemplary embodiment of the present invention is simplified in manufacturing.
Since the bumper beam 1 and the stay 5 are engaged by inserting one end of the stay 5 into the insertion hole 7 of the bumper beam 1, partial impact energy transferred from the bumper beam 1 may be transferred to a vehicle body through the stay 5 besides the bolt 15 engaging portion and thus assembling portion of the bumper beam 1 and the stay 5 may not be easily damaged or deformed. And thus, impact energy dispersion and absorption may be improved.
