  The present invention relates to a vehicle front structure.

  The following Patent Document 1 discloses a vehicle front structure having a cylindrical crash box (energy absorbing member) made of a fiber reinforced resin and a pressing member (guide member) having a convex portion that abuts on the inside of the crash box. Is disclosed.

JP 2005-233263 A

  By the way, for example, when a bumper reinforcement (hereinafter referred to as “bumper RF”) rotates in a vehicle plan view due to an offset collision, the guide member contacts the inner wall of the energy absorbing member, and the axial direction of the energy absorbing member It is conceivable that a load orthogonal to is input. However, when a load orthogonal to the axial direction is input to the energy absorbing member, the energy absorbing member is prevented from being broken in the axial direction, and the collision energy absorbing characteristic is different from the target characteristic.

  In view of the above facts, an object of the present invention is to obtain a vehicle front structure capable of obtaining stable collision energy absorption characteristics by an energy absorbing member made of a fiber reinforced resin.

  The vehicle front portion structure according to claim 1 includes a bumper reinforcement that extends in a vehicle width direction at a vehicle front portion and a fiber reinforced resin, and is located outside the vehicle width direction center of the vehicle in the vehicle width direction and the bumper reinforcement. A cylindrical energy absorbing member disposed on the vehicle rear side, a guide member provided on the vehicle rear side of the bumper reinforcement, and a part or all of the guide member disposed inside the energy absorbing member, and the guide member Is disposed inside the energy absorbing member and outside the center axis of the energy absorbing member in a vehicle plan view, and the inside of the energy absorbing member toward the inside in the vehicle width direction with respect to the bumper reinforcement. An outer guide portion that suppresses relative displacement; and provided in the guide member; It is arranged in the vehicle width direction inner side than the central axis of the energy absorbing member in both plan views to suppress relative displacement of the energy absorbing member to the vehicle width direction outer side with respect to the bumper reinforcement, and along the central axis direction. And an inner guide portion that inclines toward the central axis side toward the vehicle rear side.

  In the vehicle front structure according to the first aspect, when a collision load from the front of the vehicle is input to the bumper RF, a compressive load acts on the energy absorbing member arranged on the rear side of the bumper RF. The energy absorbing member made of fiber reinforced resin causes brittle fracture due to this compressive load, so that the collision energy is absorbed.

In addition, a guide member is provided on the vehicle rear side of the bumper RF, part or all of which is disposed inside the energy absorbing member. The guide member is provided with an outer guide portion and an inner guide portion, of which the outer guide portion is inside the energy absorbing member and outside the center axis of the energy absorbing member in a vehicle plan view. Is arranged. Thereby, an outer side guide part suppresses the relative displacement to the vehicle width direction inner side of the energy absorption member with respect to bumper RF. On the other hand, the inner guide portion is disposed inside the energy absorbing member and on the inner side in the vehicle width direction from the central axis of the energy absorbing member in a plan view of the vehicle. Thereby, an inner side guide part suppresses the relative displacement to the vehicle width direction outer side of the energy absorption member with respect to bumper RF.
That is, the relative displacement in the vehicle width direction of the energy absorbing member with respect to the bumper RF is suppressed by the guide member provided with the outer guide portion and the inner guide portion.

  Furthermore, in the vehicle front portion structure according to the first aspect, the inner guide portion is inclined toward the central axis side toward the vehicle rear side along the central axis direction of the energy absorbing member. For this reason, even when the bumper RF rotates in a vehicle plan view, the inner guide portion is unlikely to contact the inner wall of the energy absorbing member, and a load in a direction orthogonal to the axial direction is input to the energy absorbing member. Is suppressed. As a result, the destruction of the energy absorbing member in the axial direction is promoted, so that stable collision energy absorption characteristics can be obtained.

  As described above, the invention according to claim 1 has an excellent effect that a stable collision energy absorption characteristic can be obtained by the energy absorbing member made of fiber reinforced resin.

As described above, the front end of the main body cylinder portion 18 faces the rear wall 12R of the bumper RF12 in the vehicle front-rear direction. On the other hand, the rear end of the main body cylinder portion 18 opposes a front flange (not shown) of a front side member (corresponding to the crash box bottom 50, see FIG. 4) in the front-rear direction.

  The front flange portion 20 is formed to extend in the up-down direction from the front end of the main body cylinder portion 18, and is joined to the bumper RF12 with the upper wall 12U and the lower wall 12L of the bumper RF12 being added. For this joining, for example, adhesion, welding, rivets, etc. are employed. On the other hand, the rear flange portion is joined to a front side member (not shown).

And having. The guide portion 32 is configured in a substantially cylindrical shape as a whole by the upper guide portion 34, the lower guide portion 36, the outer guide portion 38 and the inner guide portion 40.

  Among these, the upper guide part 34, the lower guide part 36, and the outer guide part 38 are provided perpendicular to the flat joint part 30. On the other hand, as shown in FIG. 1, the inner guide portion 40 is perpendicular to the joint portion 30 at the base end portion 40A, but is gradually inclined outward in the vehicle width direction toward the tip end portion 40B. ing.

(Relationship between guide member and crash box)
As shown in FIG. 1, the joint portion 30 of the guide member 16 is joined to the rear wall 12R of the general portion 12A of the bumper RF12 by fasteners such as bolts and nuts (not shown). Further, the joint portion 30 of the guide member 16 is provided so as to project outward from the cylindrical guide portion 32 (left and right in FIG. 1), and the projecting portion of the main body cylindrical portion 18 is provided in the projecting portion. The front ends of the outer side wall 28 and the inner side wall 26 are abutted.

  The outer guide portion 38 of the guide member 16 is arranged in parallel to the outer wall 28 with a slight gap inside the outer wall 28 of the main body cylinder portion 18 in the vehicle width direction. Further, the inner guide portion 40 is disposed with a slight gap on the outer side in the vehicle width direction of the inner wall 26 of the main body cylinder portion 18. As described above, the outer guide portion 38 is parallel to the crash box center axis CL in the vehicle cross-sectional view, and the inner guide portion 40 is rearward of the vehicle along the direction of the crash box center axis CL in the vehicle cross-sectional view. As it goes to the side, it inclines toward the central axis CL.

  Even when the front end portion of the crash box 14 is brittle fractured and the joint between the crash box 14 and the bumper RF 12 is released (separated) in the event of a collision, the left and right sides of the crash box 14 with respect to the bumper RF 12 are configured. The positional deviation in the direction is suppressed. In other words, even if the crash box 14 is relatively displaced inward in the vehicle width direction with respect to the bumper RF12, the outer guide portion 38 of the guide member 16 contacts the outer wall 28 of the main body cylindrical portion 18, and further relative displacement is caused. Suppress. Further, even if the crash box 14 moves relative to the bumper RF12 outward in the vehicle width direction, the inner guide portion 40 of the guide member 16 comes into contact with the inner wall 26 of the main body cylindrical portion 18, and further relative displacement is suppressed. To do.

  Both the upper guide part 34 and the lower guide part 36 are formed with the vehicle vertical direction as the plate thickness direction. The upper guide part 34 is arranged below the upper side wall 22 of the main body cylinder part 18 with a slight gap, and the lower guide part 36 is slightly above the lower side wall 24 of the main part cylinder part 18. Open and arranged. Even if the joint between the crash box 14 and the bumper RF12 is released (separated) in the event of a collision, the vertical displacement of the main body cylinder portion 18 with respect to the bumper RF12 is suppressed. It has become.

(Projection amount of outer and inner guides)
Further, as shown in FIG. 3B, the protrusion amount D1 of the outer guide portion 38 toward the vehicle rear side along the crash box axis CL direction is set smaller than the protrusion amount D2 of the inner guide portion 40. Has been. In other words, the outer guide portion 38 and the inner guide portion 40 of the guide member 16 are provided with a height difference in the direction of the crash box axis CL, and the inner guide portion 40 is formed higher.

<Action and effect>
Next, the operation and effect of the vehicle front structure 10 of the present embodiment will be described.

  In the vehicle front structure 10 of this embodiment, when a collision load from the front of the vehicle is input to the bumper RF12, a compressive load acts on the crash box 14 disposed on the vehicle rear side of the bumper RF12. The crash box 14 made of fiber reinforced resin causes brittle fracture by this compressive load, so that the collision energy is absorbed.

Further, a guide member 16 that is partially or entirely disposed inside the crash box 14 is provided on the vehicle rear side of the bumper RF12. The guide member 16 is provided with an outer guide portion 38 and an inner guide portion 40. Of these, the outer guide portion 38 is inside the crash box 14 and from the center axis CL of the crash box 14 in a plan view of the vehicle. Is also arranged outside in the vehicle width direction. Thereby, the outer side guide part 38 suppresses the relative displacement to the vehicle width direction inner side of the crash box 14 with respect to bumper RF12. On the other hand, the inner guide portion 40 is disposed inside the crash box 14 and on the inner side in the vehicle width direction than the center axis CL of the crash box 14 in a plan view of the vehicle. Thereby, the inner side guide part 40 suppresses the relative displacement to the vehicle width direction outer side of the crash box 14 with respect to bumper RF12.
That is, when the front end portion of the crash box 14 is brittlely broken at the time of a collision and the joint between the crash box 14 and the bumper RF 12 is released (separated), the guide provided with the outer guide portion 38 and the inner guide portion 40 is provided. The member 16 suppresses relative displacement of the crash box 14 with respect to the bumper RF12 in the vehicle width direction.

(Suppress lateral load input to the crash box)
Further, in the vehicle front structure 10 of the present embodiment, the inner guide portion 40 of the guide member 16 is inclined toward the central axis CL side toward the vehicle rear side along the central axis CL direction of the crash box 14. . For this reason, even when the bumper RF12 rotates in a vehicle plan view, the inner guide portion 40 is unlikely to contact the inner wall 26 of the crash box 14, and a load in a direction perpendicular to the axial direction is input to the crash box 14. Is suppressed. As a result, the crash of the crash box 14 in the axial direction is promoted, and a stable collision energy absorption characteristic can be obtained. Hereinafter, a specific description will be given while comparing with the guide member 116 of the comparative example.

  As shown by a two-dot broken line in FIG. 3 (B), in the guide member 116 of the comparative example, the inner guide portion 140 is not inclined unlike the inner guide portion 40 of the present embodiment, and is viewed in a vehicle cross-sectional view. The crash box is formed in parallel with the central axis CL.

  By the way, in the collision mode such as the offset collision, as shown in FIG. 4, the bumper RF12 is mounted on the vehicle with the front end of the crash box 14R on the opposite side (right side in the figure) and the inner side in the vehicle width direction as the rotation center O. Draw a trajectory that rotates in plan view. At this time, of the guide members 16 and 116 fixed to the rear side of the bumper RF12, the collision-side guide members 16L and 116L draw a locus of rotation as shown in FIG.

  Here, in the vehicle including the guide member 116 of the comparative example, when the bumper RF12 rotates as described above, the inner guide portion 140 (particularly, the distal end portion 140B) of the guide member 116L is moved as shown in FIG. A load inward in the vehicle width direction is input to the inner wall 26 of the main body cylinder portion 18 of the crash box 14 in contact with the inner wall 26 of the main body cylinder portion 18. In other words, a load in a direction orthogonal to the crash box axial direction is input from the guide member 116 to the crash box 14. As a result, it is assumed that the inner side wall 26 of the main body cylinder portion 18 of the crash box 14 is buckled in the middle of the axial direction, and the main body cylinder portion 18 cannot be completely crushed (destroyed).

  In contrast, in the present embodiment, as indicated by a solid line in FIG. 3B, the inner guide portion 40 of the guide member 16 is a vehicle along the direction of the central axis CL of the crash box 14 in a vehicle cross-sectional view. As it goes rearward, it is inclined toward the central axis CL. For this reason, even if the bumper RF12 rotates as shown in FIG. 4, the inner guide portion 40 (particularly, the tip portion 40 </ b> B) is connected to the inner wall 26 of the main body cylinder portion 18 of the crash box 14 as shown in FIG. Therefore, it is possible to prevent a load from being input inward in the vehicle width direction from the inner guide portion 40 of the guide member 16 to the inner wall 26 of the main body cylinder portion 18 of the crash box 14. In other words, load input in a direction orthogonal to the crash box axial direction is suppressed. As a result, the inner wall 26 of the main body cylinder portion 18 of the crash box 14 is prevented from buckling in the middle of the axial direction. Therefore, the crash of the crash box 14 in the axial direction is promoted, and a stable collision energy absorption characteristic can be obtained.

(Regarding suppression of bottom of guide member)
Further, as shown in FIG. 3B, in the guide member 116 of the comparative example, there is no height difference between the outer guide portion 138 and the inner guide portion 140.

  Here, when the bumper RF12 draws a trajectory rotating in a vehicle plan view as shown in FIG. 4, the guide member 116 of the comparative example has an outer guide portion of the guide member 116 as shown in FIG. 138 abuts against the crash box bottom 50 (for example, the front flange provided at the front end of the front side member) before the inner guide portion 140. Thereby, the guide member 116 is interposed between the crash box bottom 50 and the bumper RF12, and the crash box 14 is prevented from being crushed (destructed). In other words, it is assumed that a lot of crushing margin remains in the crash box 14 due to the interposed guide member 116. Here, the crash box bottom 50 forms a plane perpendicular to the axial direction of the crash box.

On the other hand, in the guide member 16 of the present embodiment, the protrusion amount D1 of the outer guide portion 38 toward the vehicle rear side along the crash box axis CL direction is set smaller than the protrusion amount D2 of the inner guide portion 40. ing.
For this reason, as shown in FIGS. 4 and 5B, when the bumper RF12 draws a trajectory that rotates in a plan view of the vehicle, such as during an offset collision, the outer guide portion 38 of the guide member 16 crashes the bottom 50 of the crash box. It is difficult to abut. Therefore, the guide member 16 is less likely to prevent the crash of the crash box 14 in the axial direction. In other words, the crushing margin remaining in the crash box 14 is reduced by the guide member 16 interposed between the crash box bottom 50 and the bumper RF12. As a result, the crash box 14 is easily crushed (broken) in the axial direction, and thus stable collision energy absorption characteristics can be obtained.

<Modification>
In the above embodiment, the central axis CL direction of the crash box 14 is parallel to the vehicle longitudinal direction, and the axial direction of the general portion 12A, which is the portion where the crash box 14 is joined to the bumper RF12, is parallel to the vehicle width direction. However, the present invention is not limited to this. For example, the structure which concerns on a modification as shown by FIGS. 6-8 may be sufficient.

  In the vehicle front portion structure 60 of the first modified example shown in FIG. 6, the bumper RF62 has a curved shape so as to be convex in the vehicle front direction. On the other hand, the central axis of the crash box 64 is parallel to the vehicle longitudinal direction. In the vehicle front structure 70 of the second modification shown in FIG. 7, the bumper RF72 has a linear shape whose axial direction is parallel to the vehicle width direction. On the other hand, the center axis of the crash box 74 is inclined with respect to the vehicle front-rear direction so as to go inward in the vehicle width direction as it goes to the rear side of the center axis. In the vehicle front portion structure 80 of the third modified example shown in FIG. 8, the bumper RF82 has a curved shape so as to be convex in the vehicle front direction. On the other hand, the center axis of the crash box 84 is inclined with respect to the vehicle front-rear direction so as to go inward in the vehicle width direction as it goes to the rear side of the center axis.

As described above, the first to third modifications are different from the above embodiment in the shapes and arrangements of the bumper RF and the crash box, but have the same features as the above embodiment in the following points.
That is, the outer guide portion 38 of the guide members 66, 76, 86 is arranged in parallel with the outer wall 28 (crash box central axis CL) of the main body cylindrical portion 18 of the crash box 14, and the inner guide portion of the guide member 16. 40 is inclined toward the central axis CL as it goes toward the vehicle rear side along the direction of the central axis CL of the crash box 14.
For this reason, also in the first to third modifications, the inner guide portion 40 is unlikely to contact the inner wall 26 of the crash box 14 even when the bumper RF12 rotates in a vehicle plan view, such as an offset collision. The load in the direction orthogonal to the axial direction of the crash box 14 is suppressed from being input. As a result, the crash of the crash box 14 in the axial direction is promoted, and a stable collision energy absorption characteristic can be obtained.

Moreover, the said embodiment and the 1st modification-a 3rd modification have the feature which was common also in the following points.
That is, in all of the above-described embodiment and the first to third modifications, the bumper RF (and the collision-side guide member) with the front end of the crash box opposite to the collision side and the inner side in the vehicle width direction as the rotation center O. The height difference between the outer guide portion 38 and the inner guide portion 40 is set so that the outer guide portion 38 and the inner guide portion 40 of the collision-side guide member are simultaneously brought into contact with the crash box bottom 50 when the guide member is rotated. Has been.
For this reason, when drawing the locus | trajectory in which bumper RF rotates by vehicle planar view, such as at the time of an offset collision, the crush margin which remains in a crash box with the guide member interposed between the crash box bottom part 50 and bumper RF has decreased. . As a result, the crash box is easily crushed (broken) in the axial direction, and a stable collision energy absorption characteristic can be obtained.

  When the crash box bottom portion 50 forms a plane perpendicular to the crash box axial direction, the following relationship is established between the outer guide portion 38 and the inner guide portion 40 of the guide member. . That is, when viewed on the coordinate axis in the crash box axis CL direction, the vehicle rear side end portion (tip portion 40B) of the inner guide portion 40 is more than the vehicle rear side end portion (tip portion 38B) of the outer guide portion 38. It is formed to protrude to the rear side of the crash box shaft.

<Supplementary explanation of the embodiment>
In addition, in the said embodiment, although the main body cylinder part 18 of the crash box 14 was a cylindrical member with a rectangular cross section, this invention is not limited to this. The cross-sectional shape is not particularly limited, and may be a cylindrical member having a circular cross section, for example.

  Further, in the above embodiment, the outer guide portion 38 of the guide member 16 is disposed at a slight interval on the inner side in the vehicle width direction of the outer wall 28 of the main body cylinder portion 18, and the inner guide portion 40 is disposed on the main body cylinder portion 18. However, the present invention is not limited to this. For example, there may be no gap between the outer guide part and the outer wall, and there may be no gap between the inner guide part and the inner wall.

  Moreover, in the said embodiment, although the crash box bottom part 50 comprised the plane orthogonal to a crash box axial direction, this invention is not limited to this, The plane which a crash box bottom comprises is a crash box axial direction It is not necessary to be orthogonal to.

  Further, in the above embodiment and all the modified examples, when the bumper RF (and the collision side guide member) is rotated with the front end of the crash box opposite to the collision side and the vehicle width direction inner side as the rotation center O, The height difference between the outer guide portion and the inner guide portion is set so that the outer guide portion and the inner guide portion of the collision side guide member are simultaneously brought into contact with the bottom of the crash box, but the present invention is not limited to this. The height difference between the outer guide portion and the inner guide portion may be set in any way.

  Moreover, in the said embodiment, the junction part 30 of the guide member 16 is projected and provided in the outer side (right and left in FIG. 1) rather than the cylindrical guide part 32, In this projected part, The front end of the outer side wall 28 and the inner side wall 26 of the main body cylinder part 18 are abutted. Thereby, a part of guide member is in the state arrange | positioned inside the crash box. However, the present invention is not limited to this, and the entire guide member may be disposed inside the crash box. For example, the joint portion 30 of the guide member 16 is not formed with a portion protruding outward from the guide portion 32, and the front end of the outer wall 28 and the inner wall 26 of the main body cylinder portion 18 is abutted against the bumper RF12. It may be.
