[Technical field]

[0001] The present invention relates to a vehicle rear structure. [Background technology]

[0002] Generally, a rear bumper extending in the vehicle width direction is attached to the rear of a vehicle. In addition, in a vehicle having a sliding door, a rail member along which the sliding door runs is provided on the side of the vehicle body, as disclosed in Patent Document 1, for example. The rail member is a member extending in the front-rear direction of the vehicle, and is provided on the side of the vehicle body behind the closed sliding door.

[0003] As disclosed in Patent Document 1, in a structure in which the rear end of the rail member is disposed at a corner formed by the side and rear of the vehicle body, the boundaries between the exterior member of the rail member and the side body outer panel and the rear bumper are visible in a side view of the vehicle, so the positioning accuracy of these members is important. In the structure disclosed in Patent Document 1, the rear bumper is attached to the vehicle body via a bumper spacer. Furthermore, the rear part of the rail member fixed to the side of the vehicle body is also attached to the bumper spacer. In the above example structure, an attempt is made to ensure the positional accuracy of the boundary between the rear bumper and the rail member via the bumper spacer.

[0020] The inner rail cover 32 of the rail member 30 is provided with a restricting portion 34 that restricts the upper bumper holder 40 from moving in the vertical direction of the vehicle. The restricting portion 34 in this example has a through hole formed so that the round through hole and the long through hole are connected in the longitudinal direction of the vehicle, and the long through hole extends from the front of the round through hole toward the front of the vehicle. A circular engagement plate portion 48 of the upper bumper holder 40, which will be described later, engages with the restricting portion 34. The relationship between the restricting portion 34 and the engagement plate portion 48 will be described later.

[0021] The outer rail cover 38 is a member that covers the inner rail cover 32 from the outside in the vehicle width direction, and extends in the front-rear direction of the vehicle as shown in Figs. 1 to 3. A rear flange 38a that protrudes inward in the vehicle width direction is provided at the rear of the outer rail cover 38 as shown in Fig. 3. The front edge of the rear bumper 20 is disposed adjacent to the vehicle rear side of the rear flange 38a. A gap is formed between the rear flange 38a and the front edge of the rear bumper 20, and the gap extends in the vehicle up-down direction.

[0022] Next, the lower bumper holder 50 will be described. As shown in Fig. 3 and Fig. 4, the lower bumper holder 50 is disposed below and in front of the upper bumper holder 40. The lower bumper holder 50 is a member that extends at an incline downward toward the front of the vehicle, and is attached to the side body outer panel 10. The upper end of the lower bumper holder 50 corresponds to the inclination direction of the inclined surface 27 of the rear bumper 20. A plurality of engagement claws 51 are provided on the upper end. The engagement claws 51 of the lower bumper holder 50 are configured to engage with engagement holes 27a provided in the inclined surface 27 of the rear bumper 20. In this way, the rear bumper 20 and the lower bumper holder 50 are connected to each other.

[0023] Next, the upper bumper holder 40 will be described. As shown in Fig. 3 to Fig. 5, the upper bumper holder 40 is attached to a vehicle body structural member at the rear of the vehicle body, and is disposed on the vehicle lower side of the rear lamp 13. The upper bumper holder 40 of this embodiment has a main body portion 41 and an extension portion 46, as shown in Fig. 6.

[0024] The main body 41 is a portion extending in the vehicle up-down direction and has a rear wall facing the rear of the vehicle and an outer wall 43 facing the outside in the vehicle width direction. The main body 41 is also provided with an upper mounting portion 42a, a lower mounting portion 42b, a horizontal rib 45, an upper engagement claw 44a, a middle engagement claw 44b, and a lower engagement claw 44c.

[0025] The upper mounting portion 42a is a portion that protrudes from the upper end of the main body portion 41 toward the upper side of the vehicle, and is provided with a through hole through which a screw or the like can be inserted. As shown in Fig. 8, the front surface of the upper mounting portion 42a serves as a fixing portion that is fixed to the side body outer panel 10. With the front surface in contact with the side body outer panel 10, a screw or the like is inserted through the through hole and attached to a screw hole provided in the side body outer panel 10, whereby the front surface of the upper mounting portion 42a is fixed to the side body outer panel 10.

[0026] The lower mounting portion 42b is a portion that protrudes from the lower portion of the main body portion 41 toward the inside in the vehicle width direction, and as shown in FIG. 12, a through hole is provided in the same manner as the upper mounting portion 42a. The front surface of the lower mounting portion 42b is a fixed portion that is fixed to the vehicle body. The front surface of the lower mounting portion 42b is fixed to the inner panel 14 that constitutes the rear part of the vehicle body via a bracket 14a. The inner panel 14 in this example is a vehicle body component that is joined to the rear part of the side body outer panel 10 by spot welding or the like. In addition, as shown in FIG. 12, the bracket 14a has a hat shape when viewed from above, and a portion that constitutes the brim of the hat shape is joined to the inner panel 14 by spot welding or the like. The front surface of the lower mounting portion 42b is joined to the top of the hat shape by a clip or the like.

[0027] The main body 41 of this embodiment is provided with a plurality of horizontal ribs 45. The horizontal ribs 45 are plate-shaped parts that protrude horizontally from the outer wall 43 of the main body 41 outward in the vehicle width direction, and are arranged at intervals from each other in the vehicle up-down direction. As shown in FIG. 11, each horizontal rib 45 is formed to conform to the shape of the rear surface of the side wall 23 of the rear bumper 20. That is, the outer portion of at least one horizontal rib 45 in the vehicle width direction curves and bulges outward in the vehicle width direction as it moves toward the front of the vehicle. By forming the outer portion of the horizontal rib 45 in this manner, deformation of the side wall 23 of the rear bumper 20 toward the inside of the vehicle can be suppressed.

[0028] The upper engagement claw 44a, the intermediate engagement claw 44b, and the lower engagement claw 44c each protrude outward in the vehicle width direction from the front end of the outer wall 43, and are disposed at intervals from one another in the vehicle up-down direction. The upper engagement claw 44a, the intermediate engagement claw 44b, and the lower engagement claw 44c are configured to engage with an engagement hole 26a provided in the vertical surface 26 of the engaged portion 25 of the rear bumper 20.

[0029] The upper engagement claw 44a is disposed adjacent to the lower part of the front surface of the upper mounting portion 42a on the outer side in the vehicle width direction, as shown in Figures 4 and 8. The lower engagement claw 44c is disposed adjacent to the upper part of the front surface of the lower mounting portion 42b on the outer side in the vehicle width direction, as shown in Figures 4 and 12.

[0030] As shown in Fig. 6, the extension portion 46 is a portion extending from an upper portion of the body portion 41 at the outer end portion in the vehicle width direction toward the front of the vehicle. In this example, the upper end of the extension portion 46 extends horizontally from the upper portion of the body portion 41 toward the front of the vehicle, and from the intermediate portion of the extension portion 46 in the vehicle front-rear direction, it inclines downward as it moves toward the front of the vehicle, and further extends horizontally toward the front of the vehicle. The extension portion 46 is provided with a rear rail connection portion 47a and a front rail connection portion 47b. The rear rail connection portion 47a and the front rail connection portion 47b are arranged at an interval from each other in the vehicle front-rear direction, and as shown in Figs. 4 and 5, the rear holder attachment portion 33a and the front holder attachment portion 33b of the inner rail cover 32 are attached to them, respectively.

[0031] 6, an engagement plate 48 is provided on the vehicle lower side of the rear rail connection portion 47a of the extension portion 46. The engagement plate 48 is disk-shaped and is disposed on the vehicle width direction outer side from the main surface of the extension portion 46. A connection portion 48a connected to the main surface of the extension portion 46 is provided on the vehicle width direction inner surface of the engagement plate 48 as shown in FIG. 14. In the procedure for attaching the engagement plate 48 to the regulating portion 34, first, the engagement plate 48 is inserted into the through hole of the regulating portion 34. Then, the engagement plate 48 is moved relatively to the front of the vehicle with respect to the inner rail cover 32 so that the connection portion 48a is positioned in the through hole. As a result, the movement of the engagement plate 48 in the vehicle up-down direction with respect to the regulating portion 34 is restricted. Note that it is preferable that the vertical width of the through hole and the vertical width of the connection portion 48a are set so that the connection portion 48a fits into the through hole.

[0032] In addition, in this embodiment, with the engagement plate portion 48 engaged with the regulating portion 34, the rear rail connection portion 47a and the front rail connection portion 47b of the extension portion 46 are attached to the rear holder mounting portion 33a and the front holder mounting portion 33b of the inner rail cover 32 by clips or the like, and further, the upper mounting portion 42a and the lower mounting portion 42b are fixed to the side body outer panel 10 and the vehicle structural member (inner panel 14), respectively (Figure 12).

[0033] The main body 41 of the upper bumper holder 40 of this embodiment is disposed so as to be sandwiched between the side rail 31 and the rear bumper 20. As described above, the upper bumper holder 40 is attached to the side body outer panel 10 and the inner rail cover 32, and the upper engagement claws 44a and the like are disposed adjacent to the vehicle rear of the rail member 30. With this configuration, the position of the front edge of the rear bumper 20 is restricted, and it is possible to set the gap between the rear bumper 20 and, for example, the outer rail cover 38 of the rail member 30 located in front of the rear bumper 20 to be small. That is, with the above configuration, the positioning accuracy of the rear bumper 20 in the vehicle front-rear direction is improved, so that in the vehicle side view, it is possible to smoothly connect the gap formed between the rail member 30 and the side body outer panel 10 and the gap formed by, for example, the rear lamp 13 and the rear bumper 20, as if they were continuous at first glance, and as a result, the appearance characteristics of the vehicle in the vehicle side view at the rear of the vehicle are improved.

[0034] In addition, in this embodiment, the inner rail cover 32 has higher rigidity than the outer rail cover 38 having a design surface. For example, the plate thickness of the inner rail cover 32 is formed to be thicker than the plate thickness of the outer rail cover 38. In addition, the inner rail cover 32 is provided with a plurality of uneven shapes, which function as beads, improving the surface rigidity of the inner rail cover 32. By increasing the rigidity of the inner rail cover 32 in this manner, the fixed state of the rail member 30 is stabilized, and it is possible to keep a constant gap between the rail member 30 and the rear bumper 20 even if an external force acts from outside the vehicle.

[0035] In addition, the upper bumper holder 40 is provided with an extension 46. Rear rail connection portion 47a and front rail connection portion 47bBy providing the rail connecting portion 47a and the rail connecting portion 47b, it is possible to suppress the upper bumper holder 40 from moving (deforming) in the vehicle width direction. Also, it is possible to suppress the upper bumper holder 40 from rotating around an axis in the vertical direction of the vehicle. Also, in this embodiment, the rear rail connecting portion 47a and the front rail connecting portion 47b are provided on the extension portion 46 with an interval therebetween in the front-rear direction of the vehicle, so it is possible to effectively suppress the upper bumper holder 40 from rotating around an axis in the vertical direction of the vehicle.

[0036] In this embodiment, the inner rail cover 32 of the rail member 30 is provided with a restricting portion 34 for restricting the upper bumper holder 40 from moving in the vertical direction of the vehicle. The restricting portion 34 can restrict the movement of the upper bumper holder 40 in the vertical direction of the vehicle, and as a result, the position of the upper bumper holder 40 in the vertical direction of the vehicle can be effectively restricted. Furthermore, by providing the restricting portion 34 below the rear rail connection portion 47a, it becomes possible to effectively restrict the rotation of the upper bumper holder 40 about an axis in the vertical direction of the vehicle, and further, it becomes possible to effectively restrict the rotation about an axis in the front-rear direction of the vehicle.

[0037] In this embodiment, the position of at least one of the engagement claws (in this example, the upper engagement claw 44a and the lower engagement claw 44c) in the vehicle vertical direction corresponds to the vehicle vertical direction of the fixing portion where the upper bumper holder 40 is fixed to the vehicle body. In detail, the position of the upper engagement claw 44a in the vehicle vertical direction corresponds to the position where the front surface (fixing portion) of the upper mounting portion 42a and the side body outer panel 10 are fixed in abutting state. Similarly, the position of the lower engagement claw 44c in the vehicle vertical direction corresponds to the fixing position of the front surface (fixing portion) of the lower mounting portion 42b and the inner panel 14 that constitutes the vehicle body. By configuring in this way, the relative positioning accuracy of the upper bumper holder 40 and the vehicle body is improved. As a result, it is possible to keep a constant gap between the rear bumper 20 and other members.

[0038] 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.

[0039] For example, as shown in FIG. 15, a protruding portion 49 protruding outward in the vehicle width direction may be provided on the vehicle width direction outer side of the extension portion 46 of the upper bumper holder 40, and the protruding portion 49 may be configured to abut against the rear flange 38a of the outer rail cover 38. In this case, the protruding portion 49 is plate-shaped extending in the vehicle up-down direction, and the thickness of the tip portion 49a of the vehicle width direction outer side of the protruding portion 49 is formed so as to be thicker on the vehicle front side than the base portion of the protruding portion 49, and the tip portion 49a is engaged with the rear flange 38a to support the rear flange 38a. In this example, the tip portion 49a of the protruding portion 49 presses the rear flange 38a, thereby fixing the relative position of the rear flange 38a and the protruding portion 49. As a result, the gap between the rear flange 38a and the vertical surface 26 can be kept constant, and the gap between the front edge of the rear bumper 20 and the outer rail cover 38 can be further kept constant.
