Description

The present invention relates to a vehicle front structure.

In the vehicle front body structure described in Patent Document 1 below, a bumper beam extends in the vehicle width direction at the front end of the vehicle and is supported by side frames on the vehicle rear side of the bumper beam. A lower beam extends in the vehicle width direction below the bumper beam and is supported by a subframe on the vehicle rear side of the lower beam. This allows a reaction force to be applied to the colliding body (other vehicle) from the bumper beam and lower beam in the event of a frontal collision, for example. This prevents the reaction force from acting locally on the other vehicle, thereby reducing the damage to the colliding body (other vehicle) in the event of a frontal collision.

However, the above-mentioned front vehicle body structure leaves room for improvement in the following areas. For example, in an offset frontal collision, the impacting body strikes the outer portions of the bumper beam and lower beam in the vehicle width direction. However, in the early stages of the collision, the outer ends of the bumper beam and lower beam in the vehicle width direction are displaced toward the rear of the vehicle, which may prevent the bumper beam or lower beam from being crushed properly. In particular, because the bending rigidity of the lower beam is lower than that of the bumper beam, the crushing of the lower beam in the early stages of the collision tends to be unstable. This may result in reduced energy absorption in the early stages of a frontal collision.

In consideration of the above, the present invention aims to provide a vehicle front structure that can increase energy absorption in the early stages of a collision.

The following describes a vehicle (automobile) V to which a vehicle front structure S according to this embodiment is applied, using the drawings. In the drawings, the front side of the vehicle V is indicated by arrow FR, the upper side of the vehicle is indicated by arrow UP, and the left side of the vehicle (one side in the vehicle width direction) when viewed from above the vehicle is indicated by arrow LH. In addition, in the following description, when up-down, front-rear, and left-right directions are used, these directions refer to the up-down direction, front-rear direction, and left-right direction of the vehicle, unless otherwise specified.

(Overall structure)
1 to 4 , the vehicle front structure S is applied to the front of a vehicle V. The vehicle front structure S is configured to include a pair of side frames 10, a bumper beam 14, a pair of lower frames 16, and a lower beam 20.

The pair of side frames 10 are formed as hollow, roughly rectangular pillars extending in the fore-and-aft direction, and are arranged on both sides of the front of the vehicle V in the vehicle width direction (both left and right directions). Crash boxes 12 are provided in front of the side frames 10. The crash boxes 12 are formed as roughly rectangular cylinders with their axial direction extending in the fore-and-aft direction, and the rear ends of the crash boxes 12 are joined to the front ends of the side frames 10.

The bumper beam 14 extends in the vehicle width direction and has a substantially rectangular closed cross-section when viewed in the longitudinal direction of the bumper beam 14. The bumper beam 14 is joined to the front ends of the crash boxes 12 with both ends of the bumper beam 14 protruding outward in the vehicle width direction beyond the side frames 10. This indirectly connects the bumper beam 14 to the side frames 10 via the crash boxes 12. It is also possible to omit the crash boxes 12 and directly connect the bumper beam 14 to the side frames 10 by extending the front ends of the bumper beam 14 further forward than in this embodiment.

The pair of lower frames 16 are formed as hollow, roughly rectangular pillars extending in the fore-and-aft direction and are positioned below the side frames 10. That is, the lower frames 16 are positioned below the side frames 10 on both sides of the front of the vehicle V in the vehicle width direction.

The lower beam 20 is positioned in front of the pair of lower frames 16 and below the bumper beam 14, and extends in the vehicle width direction. The front ends of the lower frames 16 are joined to the outer portions of the lower beam 20 in the vehicle width direction. Details of the lower beam 20 will be described later.

A radiator support 18 is provided as a frame member between the pair of side frames 10 and the pair of lower frames 16. The radiator support 18 is formed in a generally rectangular frame shape in a front view and is configured as a support member for supporting a radiator (not shown), which is a component of the vehicle V. Specifically, the radiator support 18 includes a pair of left and right radiator support sides 18A, an upper radiator support 18B that connects the upper ends of the side radiator supports 18A, and a lower radiator support 18C that connects the lower ends of the side radiator supports 18A. The side radiator supports 18A are joined to the side frames 10 and the lower frame 16. Note that the side radiator supports 18A may also be joined to the side frames 10 or the lower frame 16.

(Regarding the lower beam 20)
The lower beam 20 is configured to include a front lower beam member 22 that forms the front portion of the lower beam 20 , and a pair of rear lower beam members 24 that form the rear portion of the lower beam 20 .

The front lower beam member 22 is made of steel plate and is formed in a generally elongated plate shape extending in the vehicle width direction. Specifically, the front lower beam member 22 is bent in a generally U-shape that opens toward the rear when viewed in the vehicle width direction. The front lower beam member 22 is also composed of a pair of side lower beam members 22A that form both longitudinal ends of the front lower beam member 22, and an intermediate lower beam member 22B that forms the longitudinal middle portion of the front lower beam member 22. Both longitudinal ends of the intermediate lower beam member 22B are joined to the transversely inner ends of the side lower beam member 22A. Specifically, the transversely inner ends of the side lower beam member 22A are positioned inside both longitudinal ends of the intermediate lower beam member 22B, and the two are joined together. Additionally, the joint 22C between the side lower beam member 22A and the intermediate lower beam member 22B is located inward in the vehicle width direction (closer to the center in the vehicle width direction) than the lower frame 16.

In addition, the portion of the front lower beam member 22 that is located outside the lower frame 16 in the vehicle width direction is slightly tilted rearward in a plan view as it moves outward in the vehicle width direction. Furthermore, the plate thickness of the intermediate lower beam member 22B is set thinner than the plate thickness of the side lower beam member 22A. As a result, the bending rigidity of the intermediate lower beam member 22B is set lower than the bending rigidity of the side lower beam member 22A. In other words, the bending rigidity of the intermediate portion of the front lower beam member 22 in the vehicle width direction is set lower than the bending rigidity of both ends of the front lower beam member 22 in the vehicle width direction.

Like the front lower beam member 22, the rear lower beam member 24 is constructed of steel plate, extends in the vehicle width direction, and is bent in a generally U-shape that opens to the rear when viewed in the vehicle width direction. The longitudinal length of the rear lower beam member 24 is set shorter than the longitudinal length of the front lower beam member 22. The rear lower beam member 24 is positioned within both vehicle width ends of the front lower beam member 22, and the front wall of the rear lower beam member 24 is spaced rearward from the front wall of the front lower beam member 22, with the upper and lower walls of the rear lower beam member 24 and the front lower beam member 22 joined together. As a result, both vehicle width ends of the lower beam 20 form a generally rectangular closed cross-sectional structure, while the vehicle width center of the lower beam 20 forms an open cross-sectional structure that opens to the rear. Furthermore, in the rear lower beam member 24, like the front lower beam member 22, the portion of the rear lower beam member 24 that is located outward in the vehicle width direction from the lower frame 16 is slightly tilted rearward in plan view as it extends outward in the vehicle width direction.

The vehicle widthwise outer end of the rear lower beam member 24 and the vehicle widthwise outer end of the front lower beam member 22 are aligned. Meanwhile, the vehicle widthwise inner end (center end) of the rear lower beam member 24 is positioned more inward than the lower frame 16 and the side lower beam member 22A. That is, the joint 22C between the side lower beam member 22A and the intermediate lower beam member 22B is positioned so as to overlap the rear lower beam member 24. The vehicle widthwise both side portions of the lower beam 20 where the rear lower beam member 24 is provided are configured as lower beam side portions 20A, and the vehicle widthwise intermediate portion of the lower beam 20 where the rear lower beam member 24 is not provided is configured as a lower beam center portion 20B (see FIG. 4). As a result, the bending rigidity of the lower beam center portion 20B of the lower beam 20 is lower than the bending rigidity of the lower beam side portions 20A.

The lower beam 20 is also provided with a pair of brackets 30 serving as connecting members. The brackets 30 are formed in a generally rectangular shape with the thickness direction extending vertically. The pair of brackets 30 are joined to the lower beam 20 and the lower radiator support 18C, connecting the lower beam 20 and the radiator support 18. Specifically, the brackets 30 are positioned so as to overlap the inner end of the rear lower beam member 24 in the vehicle width direction, connecting the lower beam 20 and the radiator support 18.

Next, we will explain the operation and effects of this embodiment.

In a vehicle V configured as described above, a bumper beam 14 and a lower beam 20 extending in the vehicle width direction are provided at the front end of the vehicle V, with the lower beam 20 positioned below the bumper beam 14. The bumper beam 14 is connected to a pair of side frames 10, and the lower beam 20 is connected to a pair of lower frames 16 positioned below the bumper beam 14.

In the event of an offset frontal collision, the impacting object B collides with the outer portion of the front end of the vehicle V in the vehicle width direction. As a result, in the event of an offset frontal collision of the vehicle V, the impacting object B is received by the bumper beam 14 and lower beam 20, and the collision load input to the bumper beam 14 and lower beam 20 can be transmitted to the side frame 10 and lower frame 16, which form the framework of the vehicle V. In other words, in the event of an offset frontal collision of the vehicle V, the impacting object B can be received over its entire surface by the bumper beam 14 and lower beam 20. As a result, the reaction force from the vehicle V to the impacting object B can be prevented from acting locally on the impacting object B. This reduces the damage to the impacting object B (the other vehicle).

Here, the lower beam 20 is composed of a front lower beam member 22 that forms the front portion of the lower beam 20, and a pair of rear lower beam members 24 that form the rear portion of the lower beam 20, with the rear lower beam members 24 being joined to both ends of the front lower beam member 22 in the vehicle width direction. As a result, the bending rigidity of the lower beam center portion 20B of the lower beam 20 is configured to be lower than the bending rigidity of the lower beam side portions 20A of the lower beam 20. This allows for increased energy absorption of the vehicle V at the beginning of an offset frontal collision.

This point will be explained below in comparison with a comparative vehicle V1. As shown in FIG. 5(A), in the comparative vehicle V1, a lower beam 200 is provided at the front end of the vehicle V1 instead of the lower beam 20 of the present embodiment. In the lower beam 200, the front lower beam portion is formed from a single member and extends in the vehicle width direction. In addition, in the lower beam 200, the rear lower beam portion is formed from a single member and, like the front lower beam portion, extends in the vehicle width direction. In other words, in the comparative vehicle V1, the bending rigidity of the lower beam 20 is configured to be uniform in the vehicle width direction. Note that in FIG. 5(A), parts configured in the same way as the vehicle V of the present embodiment are assigned the same reference numerals.

As in the present embodiment, the vehicle width directional outer portion of the lower beam 200 is positioned further outward in the vehicle width direction than the lower frame 16. Therefore, in the event of an offset frontal collision in the comparative example vehicle V1, the vehicle width directional outer portion of the lower beam 200 is displaced rearward in the early stages of the collision. However, the amount of rearward displacement of the vehicle width directional outer portion of the lower beam 200 is greater than the amount of rearward displacement of the vehicle width directional center side of the lower beam 200 (the portion positioned more inward in the vehicle width direction than the lower frame 16). In other words, the lower beam 200 is deformed such that the vehicle width directional outer portion of the lower beam 200 moves rearward away from the impact body B. Therefore, the vehicle width directional outer end of the lower beam 200 is not crushed properly, which may reduce the energy absorption capacity of the lower beam 200.

In contrast, in the vehicle V of this embodiment, as described above, the bending rigidity of the lower beam center portion 20B of the lower beam 20 is configured to be lower than the bending rigidity of the lower beam side portion 20A of the lower beam 20. Therefore, as shown in FIG. 5B , in the initial stage of an offset frontal collision of the vehicle V, the lower beam center portion 20B is primarily deformed. Specifically, the lower beam 20 bends from its transversely central portion as a starting point, and the transversely outer end of the lower beam 20 displaces forward (see the arrows in FIG. 5B ). More specifically, in a bottom view, the transversely central portion of the lower beam 20 displaces rearward, and the transversely outer end of the lower beam 20 bounces forward, deforming the lower beam 20 into a generally V-shape that opens forward (hereinafter, this deformation behavior of the lower beam 20 is referred to as V-shaped deformation behavior). As a result, compared to the comparative vehicle V1, the lower beam side portion 20A of the lower beam 20 can be crushed more effectively. This improves the energy absorption of the lower beam 20 in the early stages of an offset frontal collision.

Furthermore, as described above, in the event of an offset frontal collision of the vehicle V, the lower beam 20 bends starting from the central portion in the vehicle width direction, thereby preventing the lower beam 20 from twisting. This allows the lower beam side portion 20A to be crushed effectively.

Furthermore, as described above, in the lower beam 20, the rear lower beam member 24 is joined to both ends of the front lower beam member 22 in the vehicle width direction, making the bending rigidity of the lower beam center portion 20B lower than the bending rigidity of the lower beam side portion 20A. This allows for a lighter vehicle V than the vehicle V1 of the comparative example described above.

In addition, the inner end of the rear lower beam member 24 in the vehicle width direction is positioned more inward in the vehicle width direction than the lower frame 16. In other words, the lower frame 16 is connected to the lower beam side portion 20A, which has high bending rigidity. This allows the collision load input to the lower beam 20 to be effectively transmitted to the lower frame 16, which is a skeletal member of the vehicle V, and distributed to the rear of the vehicle V by the lower frame 16.

A radiator support 18 is provided on the rear side of the lower beam 20, connected to the side frame 10 and the lower frame 16. The vehicle widthwise inner end of the rear lower beam member 24 is connected to the radiator support lower 18C by a bracket 30. This allows the reaction force from the radiator support 18 to act on the collision body B via the lower beam 20 during an offset frontal collision, thereby improving protection performance for the vehicle V. Furthermore, as described above, the vehicle widthwise inner end of the rear lower beam member 24 is connected to the radiator support 18. That is, the radiator support 18 is connected by the bracket 30 to the lower beam side portion 20A of the lower beam 20, which has high bending rigidity. This allows the reaction force from the radiator support 18 to act on the collision body B via the lower beam side portion 20A without impeding the V-shaped deformation behavior of the lower beam 20 during an offset frontal collision.

In addition, the bending rigidity of the longitudinal middle portion of the front lower beam member 22 is configured to be lower than the bending rigidity of the longitudinal ends of the front lower beam member 22. This allows the lower beam 20 to perform a favorable V-shaped deformation behavior during an offset frontal collision.

The front lower beam member 22 is also composed of a pair of side lower beam members 22A that form both longitudinal ends of the front lower beam member 22, and an intermediate lower beam member 22B that forms the longitudinal middle portion of the front lower beam member 22. This means that, for example, by making the plate thickness of the intermediate lower beam member 22B thinner than the plate thickness of the side lower beam member 22A, the bending rigidity of the longitudinal middle portion of the front lower beam member 22 can be configured to be lower than the bending rigidity of both longitudinal ends of the front lower beam member 22. This makes it easy to set a difference in bending rigidity in the longitudinal direction in the front lower beam member 22.

In addition, in the front lower beam member 22, the joint 22C between the side lower beam member 22A and the intermediate lower beam member 22B is positioned outward in the vehicle width direction from the inner end of the rear lower beam member 24. In other words, the joint 22C is positioned in a position that overlaps with the rear lower beam member 24 in the vehicle width direction. This allows the front lower beam member 22 to be constructed from a pair of side lower beam members 22A and an intermediate lower beam member 22B, while the joint 22C is reinforced by the rear lower beam member 24.

In this embodiment, the front lower beam member 22 is composed of a pair of side lower beam members 22A and an intermediate lower beam member 22B. In other words, the front lower beam member 22 is composed of three members. Alternatively, the front lower beam member 22 may be composed of a single member. Even in this case, the bending rigidity of the lower beam center portion 20B in the lower beam 20 can be made lower than the bending rigidity of the lower beam side portion 20A.

In addition, in this embodiment, the plate thickness of the intermediate lower beam member 22B in the front lower beam member 22 is made thinner than the plate thickness of the side lower beam member 22A, and the bending rigidity of the longitudinal middle portion of the front lower beam member 22 is set lower than the bending rigidity of both longitudinal ends of the front lower beam member 22. However, the method of setting the bending rigidity difference in the front lower beam member 22 is not limited to this. For example, the tensile strength of the intermediate lower beam member 22B may be made lower than the tensile strength of the side lower beam member 22A, and the bending rigidity of the longitudinal middle portion of the front lower beam member 22 may be set lower than the bending rigidity of both longitudinal ends of the front lower beam member 22. In this case, for example, the plate thickness of the intermediate lower beam member 22B and the side lower beam member 22A can be set to the same, which can contribute to reducing the weight of the lower beam 20.
