  A vehicle employing a vehicle body rear structure according to an embodiment will be described. FIG. 1 shows a vehicle body 11 as seen from the left front side.

  As shown in FIG. 1, a vehicle body 11 forming a skeleton of a vehicle 10 includes a front floor panel 13 that forms a floor portion, and left and right left and right ends of the front floor panel 13 that extend in the front-rear direction. Side sills 14, 14, a kick-up portion 16 raised from the rear end of the front floor panel 13, and a rear floor panel 17 extending rearward from the upper end of the kick-up portion 16. The vehicle body rear structure in the present invention is based on the vehicle body 11 having such a kick-up portion 16.

  On the upper surface portion 13a of the front floor panel 13, winch devices 20 and 20 for pulling the object to be placed, a cross-shaped board support frame 30 and a cross member 18 extending in the vehicle width direction are attached. The cross member 18 has a tunnel shape. A closed cross section is formed by the cross member 18 and the upper surface portion 13 a of the front floor panel 13. As the winch devices 20, 20, a known winch device can be adopted.

  As shown in FIG. 2, an extension board 40 is attached to the upper part of the board support frame 30. The upper surface of the extension board 40 and the upper end of the kick-up portion 16 are located at the same height.

  Above the extension board 40, a stopper 50 for restricting the movement of the load in the front-rear direction is attached across the vehicle width direction. The stopper 50 is a bar-like member that is disposed above the extension board 40 with a predetermined height. When the loaded object moves forward, it comes into contact with the stopper 50. As a result, the forward movement of the loaded object from the stopper 50 is restricted. Such a stopper 50 is attached so that the position in the front-rear direction can be adjusted. Mounted on the stopper 50 are mounting plates 60, 60 on which a mounted object is mounted.

  The rear floor panel 17 is formed in a downward gradient toward the rear. The rear end of the rear floor panel 17 forms a part of a rear opening 17a that is opened and closed by a tailgate.

  As shown in FIG. 3, the board support frame 30 extends in the vehicle width direction to support the front and rear lateral beams 31 and 32 respectively supporting the front and rear edges of the extension board 40, and extends in the front and rear direction to the left and right of the extension board 40. The left and right vertical beams 33 and 33 that respectively support the edges of the beam are configured in a cross beam shape. The extension board 40 is supported by a cross beam composed of the horizontal beams 31 and 32 and the vertical beams 33 and 33. The support stability of the extension board 40 is increased by using a high-strength grid pattern.

  The extension board 40 attached to the upper portion of the board support frame 30 includes a substantially rectangular board body 41 having high rigidity and a protection mat 42 that is placed on the upper surface of the board body 41 and protects the board body 41. Since the protective mat 42 is placed, adhesion of dirt to the board body 41 can be suppressed. The protective mat 42 is a component that can be replaced at low cost.

  On the left and right ends of the extension board 40, substantially L-shaped board fixing members 70 are attached, respectively. The board fixing member 70 includes a vertical wall portion 71 that spans the front and rear horizontal beams 31 and 32, and a horizontal wall 72 that extends inward from the upper end of the vertical wall portion 71 and contacts the upper surface of the extension board 40. . In the vertical wall portion 71, vertical wall fixing holes 71a and 71b for fixing to the front and rear horizontal beams 31 and 32 are formed.

  When the extension board 40 is attached, the extension board 40 is sandwiched between the upper surfaces of the left and right vertical beams 33 and 33 and the horizontal walls 72 and 72 of the board fixing member 70. As a result, the extension board 40 is restricted from moving in the vertical direction. That is, the board fixing member 70 can be referred to as a vertical position regulating member. By regulating the movement of the extension board 40 in the vertical direction, the support stability of the extension board 40 is further increased.

  The horizontal wall 72 of the board fixing member 70 is formed with a plurality of (for example, four) stopper fixing holes 72a at different positions in the front-rear direction. These stopper fixing holes 72 a are holes for fixing the stopper 50.

  The stopper 50 can be attached to an arbitrary stopper fixing hole 72a. Thereby, the stopper 50 can adjust the position in the front-rear direction. That is, the board fixing member 70 also serves as a position adjusting mechanism for the stopper 50. Fixing portions 50 a and 50 a that are fixed to the stopper fixing holes 72 a are formed at both ends of the stopper 50.

  For example, a hole having the same diameter as the stopper fixing hole 72a is formed in the fixing portions 50a and 50a. The stopper 50 can be fixed by aligning the fixing portions 50a and 50a with an arbitrary stopper fixing hole 72a and inserting a pin. Any other configuration can be adopted as long as the stopper 50 can be adjusted in the front-rear direction.

  The mounting plate 60 is a substantially U-shaped member comprising a plate main body 61 having a substantially rectangular shape on which an object to be mounted is mounted, and wall portions 62 and 62 raised from the left and right of the plate main body 61. It is. The front ends of the plate body 61 and the wall portions 62 and 62 are welded to the stopper 50. By forming the walls 62 and 62, the left and right movement of the placement object can be restricted. Further, by welding to the stopper 50 including the wall portions 62, 62, the joining area can be increased, and the mounting plate 60 can be attached to the stopper 50 with high strength.

  The mounting plates 60 and 60 are formed integrally with the stopper 50. Thereby, the position of the mounting plates 60 and 60 is uniquely determined by adjusting the position of the stopper 50. Compared with the case where positioning is performed separately, positioning adjustment work is facilitated.

  The board fixing member 70 having a function for regulating the vertical position of the extension board 40 also serves as a position adjustment mechanism for the stopper 50. With one member, the vertical position of the extension board 40 can be regulated and the position of the stopper 50 can be adjusted, which is beneficial.

  The lateral beam 31 before constituting the board support frame 30 has fixing portions 31a and 31a for fixing the board fixing member 70 at both ends, and a bending portion 31b that is bent downward at the center. Yes. One end of the front beam mounting brackets 81 and 81 is fixed to the front transverse beam 31 at two locations so as to sandwich the curved portion 31b.

  The rear beam 32 has fixing portions 32a and 32a for fixing the board fixing member 70 at both ends, and a bending portion 32b that is bent downward at the center. A front / rear position restricting member 84 that restricts the backward movement of the extension board 40 is attached to the curved portion 32b. That is, the front / rear position restricting member 84 is a member that restricts rearward displacement by contacting the extension board 40 to which force is applied in the rearward direction. Further, rear beam mounting brackets 82 and 82 are attached in the vicinity of the fixing portions 32a and 32a.

  The front / rear position restricting member 84 can also be attached to the front transverse beam 31. In this case, the movement of the extension board 40 in the forward direction can be restricted. In addition, the front and rear position restricting members 84 can be attached to both the front and rear lateral beams 31 and 32, respectively. The movement of the extension board 40 can be restricted by the front / rear position restriction member 84. The stability of the extension board 40 is further increased.

  Returning to FIG. 1, the other end of the front beam mounting bracket 81 is fixed to the upper surface portion 13 a of the front floor panel 13. The rear beam mounting bracket 82 has a front end fixed to the cross member 18 and a rear end fixed to the front floor panel 13. The rear beam mounting bracket 82 is curved upward between the front end and the rear end, and the rear transverse beam 32 is fixed to the curved portion.

  The front end of the rear beam mounting bracket 82 is fixed to the cross member 18. The board support frame 30 is attached via a rear beam mounting bracket 82 to a high strength portion formed in a closed cross section by the front floor panel 13 and the cross member 18. The mounting rigidity and strength of the board support frame 30 are improved.

  As shown in FIG. 4, the left vertical beam 33 is crushed while the front and rear end portions 33a and 33b are bent downward. Such end portions 33a and 33b are connected to the lower portions of the front and rear transverse beams 31 and 32, respectively. The same applies to the right vertical beam (FIG. 1, reference numeral 33).

  With this configuration, the upper surfaces of the horizontal beams 31 and 32 and the vertical beam 33 can be positioned at the same height. Thereby, the extension board 40 can be supported by the four beams 31, 32, and 33, and the load applied to each beam 31, 32, and 33 can be reduced. For this reason, each beam 31, 32, 33 can be reduced in size, and the board support frame 30 as a whole can also be reduced in size.

  A left / right position restricting member 85 that restricts the leftward movement of the extension board 40 is attached to the left vertical beam 33. That is, the left / right position regulating member 85 is a member that regulates the displacement to the left by coming into contact with the extension board 40 to which a force is applied in the left direction (front side of the drawing).

  The left / right position regulating member 85 can also be attached to the right vertical beam 33. In this case, the movement of the extension board 40 in the right direction can be restricted. Further, the left and right position regulating members 85 can be attached to both the left and right vertical beams 33, respectively. The movement of the extension board 40 can be restricted by the left-right position restricting member 85. The support stability of the extension board 40 is further increased.

A bead 85c is formed toward the upper end, and an upper end portion 85d above the contact portion 85b is bent outward in the vehicle width direction.

  Since the bead 85c is formed and the upper end portion 85d is bent, the left and right position restricting member 85 has a high bending rigidity although it is a plate-like member. It is beneficial to produce a highly rigid left and right position regulating member 85 by performing simple processing on an inexpensive plate-like member. The front / rear position restricting member (FIG. 1, reference numeral 84) can also have the same configuration. In this case, the lower end is attached to the transverse beam, and the upper end is bent in the front-rear direction.

  A vertical closing member 87 (blocking member 87) that closes the space between the vertical beam 33 and the front floor panel 13 is attached to the lower part of the vertical beam 33 (board support frame 30). The vertical closing member 87 is attached across the longitudinal beam 33. A vertical closing member 87 closes the space between the vertical beam 33 and the front floor panel 13. Falling objects dropped by the occupant can be prevented from entering the area between the extension board 40 and the front floor panel 13, that is, the area surrounded by the cross-girder board support frame 30. When the carpet 93 is laid on the upper surface of the front floor panel 13, the vertical closing member 87 only needs to block between the vertical beam 33 and the carpet 93.

  As shown in FIG. 5, a horizontal blocking member 88 (blocking member 88) that closes the space between the horizontal beam 31 and the front floor panel 13 is attached to the lower portion of the front horizontal beam 31 (board support frame 30). ing. The horizontal blocking member 88 extends from the front end portion of the vertical blocking member 87 toward the vehicle width center. A horizontal blocking member 88 closes the space between the horizontal beam 31 and the front floor panel 13. It is possible to prevent an object from entering between the extension board 40 and the front floor panel 13.

The connecting plate 89 extends toward the winch device 20 and is attached to the attachment portion 20 a of the winch device 20. The front beam mounting bracket 81 is attached to the front transverse beam 31. Therefore, the transverse beam 31 before constituting the board support frame 30 is connected to the winch device 20 via the front beam mounting bracket 81 and the connecting plate 89.

  That is, at least a part of the board support frame 30 is fastened together with the winch device 20 to the front floor panel 13. By fastening the board support frame 30 together with the winch device 20, the mounting rigidity and strength of the board support frame 30 are improved. The same applies to the right winch device (FIG. 1, reference numeral 20).

  As shown in FIG. 7, the extension board 40 is attached to the same height as the front end of the rear floor panel 17, and the movement of the wheelchair 91 (mounting object 91) in the front-rear direction is restricted above the extension board 40. A stopper 50 is attached. Thereby, the wheelchair 91 can be mounted in front of the kick-up portion 16. A space ahead of the kick-up portion 16 can be utilized, and the vehicle interior can be utilized more widely.

  Since the wheelchair 91 can be mounted in front of the kick-up portion 16, the wheelchair 91 can be mounted close to the front seat 92 (conventionally, refer to the wheelchair 100 indicated by a one-dot chain line). Thereby, the occupant Mn1 of the wheelchair 91 can be seated in the vicinity of the occupant Mn2 of the front seat 92. This facilitates communication with the occupant Mn2 of the front seat 92.

  In addition, the stopper 50 is attached so that the position in the front-rear direction can be adjusted. Thereby, the position of the stopper 50 and the mounting plate 60 can be adjusted according to the size of the wheelchair 91 and the size of the occupant Mn of the wheelchair 91. Thereby, various passenger | crew Mn1 can be seated in a moderate position with respect to the front seat 92.
