DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, one embodiment of a vehicle rear structure for a vehicle according to the present invention will be described with reference to the drawings (Figs. 1 to 5). In the drawings, the direction of the arrow Fr indicates the front in the longitudinal direction of the vehicle. In the description of the embodiment, the "front (front end) and rear (rear end)" correspond to the front and rear in the longitudinal direction of the vehicle. Furthermore, the arrows R and L indicate the right and left sides when an occupant looks forward of the vehicle. Furthermore, the arrow D indicates the underside of the vehicle.

[0011] 1 to 4, the vehicle rear structure of this embodiment comprises a floor panel 10 made of a metal material that constitutes the vehicle body floor, a tail end member 30 disposed at the rear of the vehicle, a pair of side members 20 disposed on both vehicle widthwise outer sides of the floor panel 10 and extending in the fore-and-aft direction of the vehicle, and a rear cross member 13. In addition, a rear bumper 60 extending in the vehicle width direction and the like are disposed on the vehicle rear side of the tail end member 30. The structure of each member will be described below.

[0012] As shown in Fig. 2, the tail end member 30 is a panel member made of, for example, metal, provided at the rear of the floor panel 10 and extending in the vehicle width direction. A wall portion extending in the vehicle width direction is provided at the lower part of the tail end member 30, and this wall portion has a rear wall surface 33 facing the rear of the vehicle and a front wall surface 35 facing the front of the vehicle. An absorber 50 (described later) is attached to the rear wall surface 33 via a mounting panel 40. The mounting panel 40 and the absorber 50 will be described later. The floor panel 10 and the rear cross member 13 are joined to the front wall surface 35 of the wall portion of the tail end member 30.

[0013] Additionally, the upper portion of the tail end member 30 bulges toward the rear of the vehicle. That is, the upper side of the rear wall surface 33 bulges toward the rear of the vehicle. A recess 31 that is recessed downwardly of the vehicle is provided in the middle portion of the upper end of the bulging portion of the tail end member 30 in the vehicle width direction, and the bottom of the recess 31 extends in the vehicle width direction. The recess 31 is located below a tail door opening 15 provided in the rear of the vehicle body. That is, the recess 31 forms the lower opening edge of the tail door opening 15. The tail door opening 15 is an opening that is opened and closed by a tail door (not shown).

[0014] Next, the side member 20 will be described. The side member 20 is a highly rigid member that constitutes the body frame and is made of a metal material. As shown in FIGS. 2 and 3, the side member 20 is provided on the outer side of the floor panel 10 in the vehicle width direction and extends in the vehicle longitudinal direction. The side member 20 of this embodiment has a member main body 21 that extends in the vehicle longitudinal direction, a bulging member (bulging portion) 25 that is provided at the rear of the member main body 21 and extends in the vehicle longitudinal direction, and an upper panel 27, which together constitute the side member 20. The structures of the member main body 21, the bulging member 25, and the upper panel 27 will be described below.

[0015] 3, the member main body 21 extends in the front-to-rear direction of the vehicle and is joined to the outer portion of the floor panel 10 in the vehicle width direction. The member main body 21 has a U-shaped cross section that opens toward the top of the vehicle, and a flange 22 is provided on the side edge of the opening formed in the upper part of the member main body 21. The flange 22 is joined to the underside of the upper panel 27 by spot welding or the like.

[0016] As shown in Fig. 3, the bulging member 25 is provided at the rear of the side member 20. Like the member main body 21, the bulging member 25 has a U-shaped cross section that opens toward the top of the vehicle, and a flange 26 is provided at the side edge of the opening formed in the upper part of the bulging member 25. The flange 26 is joined to the underside of the upper panel 27 by spot welding or the like. Also, as shown in Fig. 4, a side wall 25b of the bulging member 25 is connected so as to be continuous with the side wall 21b of the member main body 21.

[0017] The upper panel 27 is a plate-like member that extends in the fore-and-aft direction of the vehicle and closes the openings at the top of the member main body 21 and the bulging member 25 (FIG. 2). The inner portion of the upper panel 27 in the vehicle width direction is joined to the outer portion of the floor panel 10 in the vehicle width direction. In addition, the flange 22, which is located on the inner side of the side edge of the member main body 21 in the vehicle width direction, the upper panel 27, and the floor panel 10 are joined together in a three-layer structure. Similarly, the flange 26, which is located on the inner side of the side edge of the bulging member 25 in the vehicle width direction, the upper panel 27, and the floor panel 10 are joined together in a three-layer structure.

[0018] As shown in Figure 4, the bulging member 25 bulges downward as it moves toward the rear of the vehicle. In this example, the bottom surface 25a provided at the bottom of the bulging member 25 faces the vehicle downward and is a curved surface with a predetermined curvature, curving downward as it moves toward the rear of the vehicle. In addition, the widthwise length of the bottom surface 25a of the bulging member 25 is set to be smaller than the widthwise length of the bottom surface 21a of the member main body 21, which is located further forward of the bulging member 25. Here, the widthwise direction of the bulging member 25 and the member main body 21 corresponds to the vehicle width direction.

[0019] As shown in Fig. 3, the width direction length of the bottom surface 25a of the bulging member 25 is set to gradually decrease toward the rear of the vehicle. In this example, both ends of the bottom surface 25a of the bulging member 25 in the width direction are formed to approach each other toward the rear of the vehicle. In addition, a curved portion 25d is provided at the lower part of the side wall 25b of the bulging member 25. The curved portion 25d curves from the lower end of the side wall 25b toward the center of the bulging member 25 in the width direction as it moves downward of the vehicle, and is connected to the side of the bottom surface 25a.

[0020] By providing the bulging member 25 at the rear of the side member 20, the diameter (cross section) of the side member 20 is enlarged. In this example, the dimension of the bulging member 25 in the vehicle vertical direction is larger than that of the member main body 21. This makes the side member 20 more susceptible to impacts from the rear of the vehicle. In other words, impact loads are more likely to be input to the rear of the side member 20. Furthermore, by setting the width of the bottom surface 25a of the bulging member 25 as described above, it is possible to increase the downward bulge of the bulging member 25 without interfering with other members. This increases the cross-sectional area of ​​the side member 20, allowing it to absorb impacts from the rear of the vehicle over a wider range. As a result, it is possible to effectively transmit the impact load to the front side of the vehicle via the side member 20. Furthermore, by providing the curved portion 25d, the degree of freedom in arranging members in the area between the left and right bulging members 25 is improved.

[0021] Furthermore, because the bulging member 25 of the side member 20 can effectively absorb the collision load, it is possible to suppress weight increase compared to a structure that increases rigidity against impact loads by providing the tail end member 30 with a closed cross-sectional structure, etc. Furthermore, because the bulging member 25 bulges out below the vehicle, it is possible to prevent a colliding object, etc. from penetrating below the vehicle body, thereby suppressing damage to parts arranged on the underside of the floor panel 10.

[0022] The length in the vehicle width direction in the cross section of the side member 20 is formed so that it becomes wider toward the rear of the vehicle. In this example, the width direction length of the bulging member 25 is formed so that it becomes wider toward the rear of the vehicle. This increases the area of ​​the cross section of the bulging member 25, and improves the rigidity of the rear portion of the side member 20.

[0023] In this embodiment, an absorber 50 is provided on the vehicle width direction outer side of the rear wall surface (rear surface) 33 of the tail end panel shown in Figures 2 to 5 at a position that overlaps with the bulging member 25 in a rear view of the vehicle. In this example, as shown in Figures 2 and 5, a mounting panel 40 extending in the vehicle up-down direction is joined by bolts or the like to the rear wall surface 33 of the tail end member 30 at a position that corresponds to the bulging member 25 of the side member 20. As shown in Figure 5, the mounting panel 40 is provided with bolt holes and a locking portion 41 for locking the absorber 50. The locking portion 41 protrudes from the rear surface of the mounting panel 40 toward the rear of the vehicle and has a hook shape that bends upward toward the vehicle.

[0024] Meanwhile, a locking hole 54a into which the locking portion 41 is inserted is provided in the front portion of the absorber 50, and with the locking portion 41 inserted into and hooked into the locking hole 54a, the front portion of the absorber 50 is attached to the mounting panel 40. The joining of the front portion of the absorber 50 and the mounting panel 40 will be described later.

[0025] 3, the absorber 50 of this embodiment extends outward in the vehicle width direction toward the rear of the vehicle, and at least a portion of the rear end of the absorber 50 is disposed outward in the vehicle width direction from the bulging member 25. In this example, the outer portion of the rear end of the absorber 50 in the vehicle width direction is disposed outward in the vehicle width direction from the outer portion of the bulging member 25 in the vehicle width direction.

[0026] 2 and 5, the absorber 50 has a lower member 51 and an upper member 53. The lower member 51 has a box-like shape that opens toward the top of the vehicle and has a bottom surface 51d, a rear end surface 51a, and left and right side walls 51b. The upper member 53 is a lid that covers the lower member 51 from above the vehicle and has a top surface 53d, a rear end surface 53a, and left and right side walls 53b. The rear end surface 53a of the upper member 53 is joined to an upper part of the rear end surface 51a of the lower member 51 from the rear of the vehicle. Similarly, the left and right side walls 53b of the upper member 53 are joined to the left and right side walls 51b of the lower member 51 in a state in which they cover the left and right sides of the lower member 51 from the outside.

[0027] 3, the length of absorber 50 in the vehicle width direction is set to be longer than the width direction length of bulging member 25 of side member 20, and the length of absorber 50 in the vehicle vertical direction (the distance between upper surface 53d and bottom surface 51d) is set to be shorter than the length of the rear end of bulging member 25 in the vehicle vertical direction. In this example, the distance between the front of upper surface 53d and the front of bottom surface 51d is about half the vertical dimension of the rear end of bulging member 25. In addition, the cross-sectional area of ​​absorber 50 is set to be smaller than the cross-sectional area of ​​bulging member 25 of side member 20.

[0028] This makes it possible to use the absorber 50 to initially transmit the impact load to the bulging member 25 of the side member 20. Because the absorber 50 is wider in the width direction than the bulging member 25, the load is easily transmitted to the outer shape of the side member 20 (the outline shape of the cross section). This makes it possible to transmit the load to the side member 20 efficiently. If the shape of the side member 20 and the shape of the absorber 50 were the same diameter, the rigidity of the absorber 50 would be high, making it difficult to absorb the impact. In contrast, by setting the cross-sectional area of ​​the absorber 50 as described above, the impact can be absorbed effectively.

[0029] 4 and 5, in this embodiment, the length of the absorber 50 in the vehicle vertical direction is formed to decrease toward the rear of the vehicle. A joint portion that is joined to the rear wall surface 33 of the tail end member 30 is provided at the front of the absorber 50. The joint portion of the absorber 50 in this embodiment has an upper joint portion 54 and a lower joint portion 52.

[0030] The upper joint portion 54 is a flange-shaped portion that protrudes upward from the front end of the upper surface 53d of the upper member 53 toward the vehicle. The upper joint portion 54 is fastened to the mounting panel 40 with bolts. As described above, the upper joint portion 54 is also formed with a locking hole 54a into which the locking portion 41 of the mounting panel 40 is hooked.

[0031] The lower joint portion 52 is a flange-shaped portion that protrudes downward from the front end of the bottom surface 51d of the lower member 51. Like the upper joint portion 54, the lower joint portion 52 is fastened to the mounting panel 40 with bolts. In this example, the lower joint portion 52 extends in the vehicle width direction at a position corresponding to the lower part of the bulging member 25. The upper end portion of the lower joint portion 52 and the lower end portion of the bulging member 25 are positioned so that they are at approximately the same position in the vehicle up-down direction.

[0032] When an impact load is input to absorber 50 provided at the rear of the vehicle, stress is concentrated on absorber 50 because the length of absorber 50 in the vertical direction of the vehicle is short, and absorber 50 deforms from the rear, thereby absorbing the impact load. In this example, absorber 50 is set so that the vertical dimension of the vehicle increases toward the front, and lower joint portion 52 has a shape that follows bulge member 25, so that the impact load is easily distributed to side member 20.

[0033] The absorber 50 of this embodiment has an upper surface 53d facing upward of the vehicle and side walls 51b, 53b extending downward from both ends of the upper surface 53d in the vehicle width direction. The upper surface 53d of the upper member 53 has a protruding portion 53f. The protruding portion 53f is located in a widthwise intermediate portion of the upper surface 53d, protrudes upward from the side walls 53b, and extends in the front-to-rear direction of the vehicle. Meanwhile, a bottom surface 51d of the lower member 51 has a recessed portion 51f recessed upward of the vehicle in a widthwise intermediate portion thereof.

[0034] The recessed portion 51f is disposed to correspond to the protruding portion 53f. The recessed portion 51f is disposed to overlap the bottom surface 25a of the bulging member 25 in a rear view. As shown in Fig. 5, the absorber 50 of this embodiment has a convex shape in which the central portion in the vehicle width direction protrudes upward of the vehicle as a whole, due to the protruding portion 53f on the top surface 53d of the upper member 53 and the recessed portion 51f on the bottom surface 51a of the lower member 51.

[0035] The bottom surface 25a of the bulging member 25 constituting the side member 20 overlaps with the bottom surface 51d of the absorber 50, which allows axial compressive deformation when the side member 20 is deformed. Here, axial compressive deformation does not mean that the side member 20 bends vertically or horizontally, but rather that the side member 20 can deform while maintaining a constant load direction, similar to the way a bellows hose expands and contracts, undergoing primarily contractive deformation. Deforming in this manner makes it possible to further improve the impact absorption efficiency.

[0036] The absorber 50 of this embodiment is a hollow columnar structure made up of an upper member 53 and a lower member 51, and has notches 57 formed in the rear end faces 51a, 53a of the absorber 50. The notches 57 are formed on the vehicle width direction outer side of the rear end face 53a of the upper member 53 and on the vehicle width direction outer side of the rear end face 51a of the lower member 51, respectively, and the notches 57 formed in each rear end face 51a, 53a form through-holes that penetrate in the fore-and-aft direction of the vehicle. The portions where the notches are formed are more vulnerable to impact loads from the rear of the vehicle than other portions. This allows for more effective impact absorption.

[0037] Furthermore, since the tip portion of the absorber 50 is reliably crushed, the absorber 50 can more easily absorb the load. Furthermore, since the notches 57 are provided near the corners at the rear end of the absorber 50, it is possible to weaken the corners, which tend to be highly rigid. As a result, this configuration can make the absorber more susceptible to crushing under impact loads.

[0038] In this embodiment, the rear cross member 13 is joined to the tail end member 30 and the bulge member 25. As shown in FIG. 4 , a lower flange 13a extending in the vehicle width direction is provided at the lower rear portion of the rear cross member 13, and the lower flange 13a is joined to a front wall surface (front portion) 35 of the tail end member 30 by spot welding or the like. An upper flange 13b extending in the vehicle width direction is provided at the upper front portion of the rear cross member 13, and the upper flange 13b is joined to the underside of the floor panel 10 by spot welding or the like. An outer flange 13d extending in the vehicle front-rear direction is provided at the lower portion of the outer portion of the rear cross member 13 in the vehicle width direction, and the outer flange 13d is joined to a side wall 25b of the bulge member 25. The outer portion of the upper flange 13b in the vehicle width direction may also be joined to the flange 26 of the bulge member 25.

[0039] This makes it possible to expand the range over which load can be transmitted to the bulging member 25. Furthermore, since the rigidity of the bulging member 25 is improved, it is possible to suppress deformation of the bulging member 25, thereby improving collision performance. In addition, since the bulging member 25 and the member main body 21 are made of separate parts, it is possible to change the thickness.

[0040] As shown in Figures 1 and 3, the rear bumper 60 is a plate-like body that is elongated in a generally rectangular shape, and both side portions 61 in the vehicle width direction are bent toward the front of the vehicle to form a generally arcuate surface. As shown in Figure 3, a light emitting portion 70 is disposed on the outer side of the absorber (or impact absorber) 50 in the vehicle width direction and on the inner side of both side portions 61 in the vehicle width direction of the rear bumper 60. The position of the rear end surface 53a of the absorber 50 in the vehicle front-rear direction is rearward of the position of the light emitting portion 70 in the vehicle front-rear direction. Examples of the light emitting portion 70 include a backup lamp and a turn signal lamp. The light emitting portion 70 may be at least a part of a rear combination lamp.

[0041] As described above, the vehicle rear structure according to one embodiment includes a floor panel 10, side members 20 joined to vehicle width direction ends of the floor panel 10 and extending in the vehicle front-rear direction, a tail end member 30 joined to the rear end of the side member 20, a rear bumper 60 disposed behind the tail end member 30, and a light emitting portion 70. An absorber 50 is provided that is connected to the rear end of the side member 20 via the tail end member 30. In a bottom view, the light emitting portion 70 is disposed outside the absorber 50 in the vehicle width direction and inside both vehicle width direction side portions 61 of the rear bumper 60. The absorber 50 extends outward in the vehicle width direction as it approaches the rear of the vehicle. The position of the rear end surface 53a of the absorber 50 in the vehicle front-rear direction is rearward of the position of the light emitting portion 70 in the vehicle front-rear direction.

[0042] With the above-described configuration, when a collision object BR (FIGS. 1 and 3) hits the vehicle relatively lightly from diagonally behind, the shock is more easily absorbed by the absorber 50, which extends outward in the vehicle width direction as it moves toward the rear of the vehicle, thereby increasing the possibility of protecting the light emitting unit 70. In addition, because the absorber 50 almost overlaps with the side member 20 when viewed from the rear of the vehicle, it can also cope to a certain extent with collisions from directly behind the vehicle.

[0043] The rear end surfaces 51a and 53a constituting the rear end of the absorber 50 may have a curved portion as a whole. This curved portion may be curved so as to be convex toward the rear of the vehicle in any of a bottom view, a side view, or a bottom view and a side view. In this case, the curved portion of the absorber 50 is located closer to the light-emitting portion 70 in a bottom view than when the absorber extends directly behind the vehicle. Therefore, the curved portion makes it easier to receive an object colliding with the vehicle from diagonally behind, further improving the effect of preventing damage to the light-emitting portion 70.

[0044] The rear cross member 13 extending in the vehicle width direction may be joined to the front wall surface (surface on the vehicle front side) 35 of the tail end member 30, and the vehicle width direction end of the rear cross member 13 may be joined to the rear end of the side member 20. More specifically, an outer flange 13d provided on a lower part of the vehicle width direction outer part of the rear cross member 13 may be joined to the side wall 25b of the bulging member 25 of the side member 20. In this case, the rear cross member 13 is joined to the side member 20 and the tail end member 30, and the absorber 50 is joined to a corner formed by the rear end of the side member 20 and the vehicle width direction end of the rear cross member 13. Therefore, even if an object collides with the side member 20 from directly behind or diagonally behind the vehicle, the absorber 50 is firmly supported by the corner, thereby achieving both prevention of damage to the light emitting unit 70 and safety performance in a rear collision.

[0045] The absorber 50 includes an upper member 53 and a lower member 51, which are located respectively above and below the vehicle in the vertical direction, and the upper member 53 may be joined to the lower member 51 so that the upper member 53 covers the lower member 51. In this case, the two members overlap horizontally at their joints, resulting in high rigidity. This joint extends to both sides and the rear end of the absorber 50 in the vehicle width direction. Therefore, in the event of a relatively minor collision, the impact load is transmitted from the joint at the rear end of the absorber 50 to the joints at both sides of the absorber 50 in the vehicle width direction. Furthermore, if the load is transmitted to the tail end member 30 and the collision is relatively minor, the absorber 50 will not deform and the light-emitting unit 70 can be protected.

[0046] The upper member 53 may have a protrusion 53f formed between the rear end 53a and the joint with the tail end member 30 and protruding above the vehicle, while the lower member 51 may have a recess 51f formed between the rear end 51a and the joint with the tail end member 30 and recessed above the vehicle. In this case, the load caused by a collision is transmitted along the protrusion 53f and the recess 51f. Therefore, in the case of a minor impact, the amount of penetration of the colliding object into the vehicle interior can be reduced in the direction along the protrusion 53f and the recess 51f. Furthermore, the recess and protrusion make the absorber 50 less likely to be crushed in the vertical direction. Note that if the recess and protrusion are aligned in height with the bottom surface 25a of the bulging member 25, the axial compressive deformation described above is promoted.

[0047] The lower end surface of the rear end 53a of the upper member 53 and the upper end surface of the rear end 51a of the lower member 51 may be joined, and the lower end surfaces of the upper member 53 at both vehicle width direction sides and the upper end surfaces of the lower member 51 at both vehicle width direction sides may be joined, respectively. Furthermore, the vertical dimension of the absorber 50 may be formed so as to gradually increase from the rear end toward the front of the vehicle. In this case, the load is transmitted along the joint between the upper member 53 and the lower member 51 of the absorber 50. Furthermore, since the vertical dimension gradually increases toward the front of the vehicle, the load is more likely to be distributed to the tail end member 30. In other words, it is possible to reduce the amount of intrusion of a colliding object during a minor collision, further improving the possibility of protecting the light emitting unit 70.

[0048] An absorber mounting panel 40 (FIG. 5) and a side member mounting panel 80 (FIG. 4) may be joined to the tail end member 30 so as to face each other with the tail end member 30 in between. In this case, the absorber 50 is joined to the absorber mounting panel 40, and the side member 20 is joined to the side member mounting panel 80. As a result, the absorber mounting panel 40, the tail end member 30, the side member mounting panel 80, and the side member 20 are arranged so as to overlap with the absorber 50 when viewed from the rear of the vehicle. Because the absorber 50 is supported by the absorber mounting panel 40, the fixing strength of the absorber extending diagonally rearward is increased, making it less likely that the tail end member 30 will be dented during a collision. In other words, the possibility of damage to the light emitting unit 70 during a minor collision is further reduced.

[0049] The description of the present embodiment is merely an example for explaining the present invention, and does not limit the invention described in the claims. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0050] In this embodiment, the bottom surface 25a of the bulging member 25 is curved, but this is not limited to this. For example, the bottom surface 25a of the bulging member 25 may be formed so as to extend at an angle downward toward the rear of the vehicle. Also, in this embodiment, the member main body 21 and the bulging member 25 are separate members, but they may also be configured as an integrated unit, for example. [Explanation of symbols]
