Description

  The present invention relates to a structure for reinforcing a rear vehicle body of a vehicle, and belongs to the technical field of the vehicle body structure.

  An opening for the back door may be formed on the rear wall of the vehicle body. However, when the opening is formed in this way, the rear wall of the vehicle body is easily deformed into a parallelogram shape as shown by a one-dot chain line or a dotted line in FIG. Thus, the torsional rigidity at the rear of the vehicle body is reduced. In order to deal with this problem, the applicant of the present application has proposed a rear body structure shown in Patent Document 1. That is, the front surface of the side portion of the opening in the rear wall of the vehicle body and the upper portion of the rear wheel house formed so as to bulge inward of the vehicle body from the vehicle body side wall in front of the vehicle body rear wall are connected substantially front and rear. A connecting member is provided. According to such a structure, the opening side portion of the rear wall of the vehicle body is connected to the rigid rear wheel house via the connecting member, so that the opening side portion is less likely to fall down in the vehicle width direction. That is, it becomes difficult for the rear wall of the vehicle body to be deformed into a parallelogram, and the torsional rigidity of the rear portion of the vehicle body is improved.

  However, even when the rear body structure as described above is adopted, it has been found that there are the following problems. That is, as shown in FIG. 8, the opening side portion of the rear wall of the vehicle body and the rear end portion of the connecting member are connected in a dotted shape in a side view, and as a result, as shown by a one-dot chain line or a dotted line in this figure. In addition, it is difficult to restrain the rear wheel house and the opening side portion of the rear wall of the vehicle body from being relatively displaced up and down. If this displacement occurs at different phases on the left and right sides of the vehicle body, the rear wall of the vehicle body is torsionally deformed into a parallelogram shape, as indicated by the alternate long and short dash line in FIG.

  Therefore, an object of the present invention is to provide a vehicle rear body structure that can further improve the rigidity of the rear portion of the vehicle body, particularly the torsional rigidity.

  In order to solve the above-described problems, the present invention is configured as follows.

In the first aspect of the present invention, a back door opening is formed in the rear wall of the vehicle body, and a rear wheel house bulging inward from the vehicle body side wall is formed in front of the vehicle rear wall. And a vehicle rear body structure comprising a connecting member that connects the front surface of the side portion of the opening in the rear wall of the vehicle body and the upper portion of the rear wheel house substantially front and rear, A coupling member is provided for coupling the member and the front surface of the opening side portion of the rear wall of the vehicle body , and the coupling member is obliquely rearward and upward from the upper surface of the coupling member toward the front surface of the opening side portion of the vehicle body rear wall. A lateral wall portion that is connected to the inner surface of the vehicle body side wall and spaced apart from and substantially parallel to the vehicle body side wall, and from the lateral wall portion toward the vehicle body side wall inner surface. A vertical wall extending substantially in the vehicle width direction, In addition, a cut-and-raised portion is formed on the upper surface of the connecting member, and a lateral wall portion of the coupling member and a cut-and-raised portion of the connecting member are overlapped, and in this overlapped portion, a seat belt retractor is connected to the connecting member And a connecting member .

According to a second aspect of the present invention, in the rear body structure of the vehicle according to the first aspect , the seat belt retractor is supported in the vicinity of an attachment portion of the coupling member with respect to the connecting member, The coupling member extends in a direction in which the seat belt extends from the seat belt retractor.

  Next, the effect of the present invention will be described.

  First, according to the first aspect of the present invention, in the configuration in which the front surface of the side portion of the opening in the rear wall of the vehicle body and the upper portion of the rear wheel house are coupled by the coupling member, Since a connecting member is provided to connect the front side of the opening side part, the integrity of the connecting member and the opening side part of the rear wall of the vehicle body, and thus the side of the rear wall of the vehicle rear wall from the rear wheel house in the rear part of the vehicle body The integrity of the part leading to the part is increased, and the rigidity of the rear part of the vehicle body is improved.

  In particular, as can be seen from FIG. 10 (description of the present invention), according to such a structure, the rigidity of the coupling portion between the connecting member and the opening side portion of the rear wall of the vehicle body is improved, which will be described in the background art. Thus, the relative vertical displacement between the rear wheel house and the left and right opening side portions of the rear wall of the vehicle body is suppressed, and as a result, the torsional deformation due to the occurrence of this displacement in different phases on the left and right sides of the vehicle body is minimized. It will be suppressed. That is, the torsional rigidity at the rear of the vehicle body is improved. FIG. 10 is an example, and the shape of the coupling member may be, for example, a rod shape. Further, the coupling member may be provided on the lower surface side of the coupling member.

Further, according to the present invention , the coupling member can be configured by a member having a simple structure extending obliquely rearward and upward from the upper surface of the coupling member toward the front surface of the opening side portion of the rear wall of the vehicle body. Further, the connecting member and the opening side portion can be effectively coupled in a brace shape.

  By the way, when the coupling member is not provided and the rigidity of the coupling portion between the vehicle body side wall and the vehicle body rear wall is not sufficient, the angle formed by the two walls is as shown by a dashed line or a dotted line in FIG. There is a possibility that the rear wheel house and the opening side portion of the rear wall of the vehicle body are relatively displaced in the vehicle width direction. And even if the said coupling member is provided, this problem is as much as the case where the coupling member is not provided when the outer end portion in the vehicle width direction of the coupling member is not connected to the inner surface of the vehicle body side wall. However, there are similar concerns. From the viewpoint of improving the rigidity of the rear part of the vehicle body, it is preferable that this point can also be suppressed.

Therefore, in the present invention , the outer end of the coupling member in the vehicle width direction is coupled to the inner surface of the vehicle body side wall. According to this, the vehicle body side wall and the vehicle body rear wall are coupled via the coupling member. Thus, the integrity of the vehicle body side wall and the vehicle body rear wall, and in turn, the integrity of the portion from the rear wheel house to the opening side portion of the vehicle body rear wall at the rear of the vehicle body are further improved. Therefore, the displacement of the rear wheel house and the opening side portion of the rear wall of the vehicle body in the vehicle width direction is suppressed as described above.

Further, according to the present invention , the coupling member includes a horizontal wall portion that is spaced apart and substantially parallel to the side wall of the vehicle body, and a vertical wall that extends in the vehicle width direction from the horizontal wall portion toward the inner surface of the vehicle body side wall. Therefore, the rigidity of the coupling member itself, and hence the torsional rigidity of the rear part of the vehicle body, can be further improved.

  By the way, there is a case where a rear seat is provided in the vicinity of the rear wall of the vehicle body at the rear portion of the vehicle body. Although it is attached inside, it may not be attached to the side wall of the vehicle body due to the positional relationship with the shoulder anchor or the like.

Therefore, in the present invention , the seat belt retractor is supported by using the coupling member provided inside the vehicle body side wall. In this case, the coupling member is a reinforcing member, and usually has a higher rigidity than the panels constituting the inner surface of the vehicle body side wall or the vehicle body rear wall, so that the support rigidity of the seat belt retractor is appropriately set. It can be secured.

In the present invention , the seat belt retractor is supported by using the connecting member provided on the inner side of the side wall of the vehicle body. In this case, the connecting member is a reinforcing member, and usually has a higher rigidity than the panels constituting the inner surface of the vehicle body side wall or the vehicle body rear wall, so that the support rigidity of the seat belt retractor is appropriately set. It can be secured.

  By the way, when supporting a seatbelt retractor using a connection member, there exists a subject of what kind of structure it makes concrete.

In order to solve this problem, in the present invention , a cut-and-raised portion is formed on the upper surface of the connecting member, and the seat belt retractor is supported by the cut-and-raised portion. In that case, when the cut-and-raised portion is formed in this way, the cross-sectional shape of the cut-and-raised portion and the portion continuing to the cut-and-raised portion is substantially L-shaped, so the rigidity around the cut-and-raised portion that supports the seat belt retractor Will be improved. Therefore, it is possible to appropriately ensure the support rigidity of the seat belt retractor.

Also, the invention, when the has cut-and-raised portion is formed as, and said coupling member has a transverse wall portion provided substantially in parallel spaced relative to the vehicle body side wall The lateral wall portion of the connecting member and the cut-and-raised portion of the connecting member are superposed, and the seat belt retractor is supported by the superposed portion. In this case, since the overlapping portion has higher rigidity than the lateral wall portion of the coupling member and the cut-and-raised portion of the connecting member, the support rigidity of the seat belt retractor can be further improved.

On the other hand, according to the invention described in claim 2 , the seat belt retractor is supported in the vicinity of an attachment portion of the coupling member with respect to the coupling member, and the coupling belt extends from the seat belt retractor. Since the seat belt is locked by the seat belt retractor due to, for example, a frontal collision, and the pulling force acts on the retractor in the extending direction of the seat belt, the coupling member It can effectively counter.

  Next, functions and effects of the rear body structure of the vehicle according to the present embodiment will be described.

  That is, according to the rear vehicle body structure according to the present embodiment, in the configuration in which the front surface 32a of the side portion 32 of the opening 31 in the vehicle body rear wall 3 and the upper portion of the rear wheel house 43 are connected by the connecting member 50. Since the connecting member 70 is provided to connect the connecting member 50 and the front surface 32a of the opening side portion 32 of the vehicle body rear wall 3, the connection member 50 and the opening side portion 32 of the vehicle body rear wall 3 are integrated. As a result, the integrity of the portion from the rear wheel house 43 to the opening side portion 32 of the vehicle body rear wall 3 at the rear portion of the vehicle body is increased, and the rigidity of the vehicle body rear portion is improved.

  In particular, as can be seen from FIG. 10, according to such a structure, the rigidity of the connecting portion between the connecting member 50 and the opening side portion 32 of the vehicle body rear wall 3 is improved. Relative vertical displacement between the wheel house and the left and right opening side portions of the rear wall of the vehicle body is suppressed, and as a result, torsional deformation due to this displacement occurring at different phases on the left and right sides of the vehicle body is suppressed as much as possible. It becomes. That is, the torsional rigidity at the rear of the vehicle body is improved. When only such an effect needs to be achieved, the coupling member may be provided on the lower surface side of the connecting member.

  Further, the rear upper extending portion 70A of the coupling member 70 is a member having a simple structure extending obliquely rearward and upward from the upper surface of the flat portion 50a of the connecting member 50 toward the front surface 32a of the opening side portion 32 of the vehicle body rear wall 3. Can be configured. Further, the connecting member 50 and the opening side portion 32 can be effectively coupled in a brace shape.

  In the present embodiment, since the outer end portion (outer flange portion 70c) in the vehicle width direction of the coupling member 70 is coupled to the inner surface of the vehicle body side wall 4, the vehicle body side wall 4 and the vehicle body rear wall 3 are coupled to each other. 70, the vehicle body side wall 4 and the vehicle body rear wall 3 are integrated with each other. As a result, the integration of the rear wheel house 43 at the vehicle body rear portion to the opening side portion 32 of the vehicle body rear wall 3 is improved. Further improve. Therefore, relative displacement of the rear wheel house and the opening side portion of the rear wall of the vehicle body in the vehicle width direction is suppressed as shown in FIG.

  In addition, the coupling member 70 includes a lateral wall portion 70a that is spaced apart and substantially parallel to the vehicle body side wall 3, and a vertical wall portion 70b that extends in the vehicle width direction from the lateral wall portion 70a toward the inner surface of the vehicle body side wall 4. Therefore, the rigidity of the coupling member 70 itself, and thus the torsional rigidity of the rear part of the vehicle body is further improved.

  By the way, the retractor 63 is usually disposed in the vicinity of or inside the side wall of the vehicle body. In the present embodiment, the shoulder anchor 64 is related to the shape of the D pillar portion provided at the upper part of the opening side portion 32. There is a situation in which the retractor 63 cannot be attached to the vehicle body side wall 4 because it must be provided above the opening end surface 32b of the opening side portion 32.

  Therefore, in the present embodiment, the retractor 63 is supported by using the connecting member 70 and the connecting member 50 provided inside the vehicle body side wall 4. In this case, the connecting member 70 and the connecting member 50 are reinforcing members, and have greater rigidity than the panels constituting the inner surfaces of the vehicle body side wall 4 and the vehicle body rear wall 3.

  Further, in the present embodiment, the lateral wall portion 70a of the coupling member 70 and the cut-and-raised portion 50g of the connecting member 50 are superposed, and the retractor 63 is supported by this superposed portion. In this case, since this overlapping portion is higher in rigidity than the lateral wall portion 70a of the coupling member 70 and the cut-and-raised portion 50g of the connecting member 50, the support rigidity of the retractor 63 can be further improved.

  In the present embodiment, the retractor 63 is supported in the vicinity of the attachment portion of the coupling member 70 with respect to the coupling member 50, and the coupling member 70 extends from the retractor 63 in the direction in which the seat belt 61 extends. Even if, for example, the seat belt 61 is locked by the retractor 63 due to a front collision or the like, and the pulling force acts on the retractor 63 in the extending direction of the seat belt 61, the coupling member 70 can effectively cope with the load. You can counter it.

The width of the lower end portion of the vertical wall portion 90b is made larger than that of the first embodiment and is substantially the same as the width of the connecting member 50. Further, the coupling member 90 has an inner flange portion 90d that extends rearward along the inner flange portion 50c of the connecting member 50 from the lower end of the lateral wall portion 90a of the rear upward extending portion 90A and is joined to the inner flange portion 50c. The inner flange portion 90d constitutes a rear extension 90B. Further, as shown in FIG. 6, the coupling member 90 extends from the inner flange portion 90d outward in the vehicle width direction to the cut-and-raised portion 50g and is superposed on the cut-and-raised portion 50g. And an extension mounting portion 90e in which a bolt insertion hole 90h corresponding to the bolt insertion hole 50h of the shoulder portion 50g is formed. A portion of the extension mounting portion 90e that contacts the flat portion 50a of the connecting member 50 is joined to the flat portion 50a.

  Then, the attaching portion 63d of the belt retractor 63 is overlapped on the overlapped portion, the bolt 81 is inserted into the bolt insertion holes 63h, 50h, and 90h and fastened with the nut 82, so that the seat belt retractor 63 The coupling member 50 and the coupling member 90 are both fixed and supported.

  The coupling member 90 connects the upper end of the rear upper extending portion 90A and the rear end of the rear extension 90B, and is joined to the opening end surface portion 32b of the opening side portion 32 of the vehicle body rear wall 3. Thus, the coupling member 90 has a substantially triangular frame-like structure.

  According to the second embodiment, the rigidity of the coupling member 90 is further improved by providing the rear coupling portion 90f. Therefore, the operational effect relating to the improvement in rigidity described in the first embodiment can be obtained more effectively.
