[0004] Vehicles include various reinforcement members for suppressing deformation of the vehicle body and improving the rigidity of the vehicle body. The reinforcement member may have various structures in consideration of the installation position of the reinforcement member, connection with peripheral components / parts, etc.

[0005] A vehicle may include a partition through which a passenger compartment and a rear compartment (luggage space, trunk, etc.) are separated. According to the related art, the rigidity of the partition may be increased by a reinforcing member having a single cross section.

[0006] However, since the reinforcement member of the related art has a single cross section, it is difficult to suppress deformation of the bulkhead and the vehicle body. In particular, there is a limit to increasing the rigidity of the bulkhead and the vehicle body.

[0007] The above information provided in this Background section is used to help understanding the background of the inventive concept and may contain any technical concepts known to those skilled in the art that are not considered to be prior art. Summary of the invention

[0017] The vehicle reinforcement member further includes an upper connecting portion connecting a top end of the first extending portion and a top end of the second extending portion to the upper mounting portion.

[0018] The cross section of the upper connecting portion gradually changes from the top end of the first extending portion and the top end of the second extending portion toward the upper mounting portion.

[0019] The lower mounting portion is offset relative to the bottom ends of the first extension portion and the second extension portion.

[0020] The vehicle reinforcement member further includes a lower connecting portion connecting a bottom end of the first extending portion and a bottom end of the second extending portion to the lower mounting portion.

[0021] The cross-section of the lower connecting portion gradually changes from the bottom ends of the first extending portion and the second extending portion toward the lower mounting portion.

[0062] Terms such as first, second, A, B, (a), and (b) can be used to describe elements in exemplary embodiments of the present invention. These terms are only used to distinguish one element from another element, and the inherent characteristics, order or sequence of the corresponding elements are not limited by the terms. Unless otherwise specified, all terms used herein, including technical or scientific terms, have the same meaning as those of ordinary skill in the art to which the present invention belongs. Such terms defined in commonly used dictionaries are interpreted as having the same meaning as the contextual meaning in the relevant technical field, and should not be interpreted as having an ideal or overly formal meaning, unless explicitly defined as having such meaning in this application.

[0063] refer to Figure 1 , a vehicle body includes a partition 1 between a passenger compartment and a rear compartment (luggage space, trunk, etc.). The partition 1 may have a front wall 2 and a top wall 3 extending horizontally from a top edge of the front wall 2 toward the rear of the vehicle body. The front wall 2 may include an upper portion 2a and a pair of side portions 2b. The front wall 2 may have an opening 2c defined by the upper portion 2a and the pair of side portions 2b.

[0064] The bulkhead 1 may be configured to separate a passenger compartment from a rear compartment at the rear of the vehicle body. When the strength and rigidity of the bulkhead 1 are not obtained, vehicle body deformation may occur. Therefore, at least one reinforcing member 10 is installed on the bulkhead 1 to increase the rigidity and strength of the bulkhead 1.

[0065] refer to Figure 1 , the two reinforcing members 10 may be symmetrically and obliquely arranged with respect to the partition 1. Each reinforcing member 10 may extend to a predetermined length, and a pair of mounting portions 13 and 14 may be arranged at both ends of the reinforcing member 10. Figure 2 The upper mounting portion 13 of each reinforcing member 10 may be mounted on the upper portion 2a of the front wall 2 of the partition 1 using a fastener such as a bolt 87. Figure 3 The lower mounting portion 14 of each reinforcement member 10 may be mounted on the side portion 2b of the front wall 2 of the partition 1 using a fastener such as a bolt 87. The upper mounting portion 13 and the lower mounting portion 14 may have a single cross-section.

[0066] refer to Figure 1 and Figure 4 , the reinforcing member 10 may include a first extension portion 11 extending in the longitudinal direction thereof and a second extension portion 12 spaced apart from the first extension portion 11. The second extension portion 12 may be parallel to the first extension portion 11, and the length of the second extension portion 12 may be equal to or similar to the length of the first extension portion 11. Therefore, the reinforcing member 10 may have a double cross-section consisting of a cross-section of the first extension portion 11 and a cross-section of the second extension portion 12. The cross-section of the first extension portion 11 and the cross-section of the second extension portion 12 may have various shapes, for example, circular, triangular, and rectangular shapes. The top end of the first extension portion 11 and the top end of the second extension portion 12 may be integrally connected to the upper mounting portion 13, and the bottom end of the first extension portion 11 and the bottom end of the second extension portion 12 may be integrally connected to the lower mounting portion 14.

Figure 6 , the longitudinal axis L1 of the first extension portion 11 may be spaced apart from the longitudinal axis L2 of the second extension portion 12 by a first distance d1 along the longitudinal axis X of the vehicle body. When the first extension portion 11 is spaced apart from the second extension portion 12, the secondary moment of area IYY of the reinforcement member 10 with respect to the width axis Y of the vehicle body may increase, and when the secondary moment of area IYY with respect to the width axis Y of the vehicle body increases, the bending rigidity of the reinforcement member 10 with respect to the bulkhead 1 and the longitudinal axis X of the vehicle body may be improved.
