The present invention relates to a vehicle body rear structure.

  Conventionally, for example, a sports utility truck that is composed of a car body that opens the rear of the minivan's compartment, and that allows the partition gate to divide the compartment and the outdoor cargo compartment to fall down and expand the cargo compartment into the compartment. It has been known.

  Such sports utility trucks have a rear seat that can be double-folded, and the rear structure of the vehicle body that tilts the collapsible partition gate that separates the passenger compartment and the outdoor cargo compartment in the state that the rear seat is double-folded is known. (For example, refer to Patent Document 1). In this vehicle body rear structure, normally, the enlarged cargo compartment member is folded and the front portion thereof is disposed at the lower portion of the rear seat, and the rear portion is folded to stand behind the rear seat to form the partition gate. On the other hand, when the cargo compartment is expanded, the rear seat is double folded and the enlarged cargo compartment member is deployed, so that the rear end is opened and the rear part reaches the outdoor cargo compartment beyond the passenger compartment. A flat bed is formed.

In Patent Document 2, a sports utility track is provided with a rear floor, a deck floor panel positioned above the rear floor with a predetermined interval, and a closing panel directly connected to the rear floor panel on the front side of the deck floor panel.

  However, in the rear structure of the vehicle body of Patent Document 1, although a load straddling the passenger compartment and the outdoor luggage compartment can be placed on a flat enlarged luggage compartment member, a rear seat is used to form the bottom of the flat luggage compartment. A double holding structure is required. For this reason, the structure of the rear seat becomes complicated, which is disadvantageous in terms of cost.

  On the other hand, in the rear structure of the vehicle body of Patent Document 2, since the partition gate is moved forward, when the rear seat has a single folding structure, if a flat cargo compartment is to be formed, the bottom of the cargo compartment is separated from the seat back and the partition. There is a problem in that the position in the vertical direction of the cargo room becomes narrower because the position is higher than the thickness of the gate.

  The present invention has been made in view of the above points, and an object of the present invention is to form a flat and wide luggage compartment with a simple configuration even when the rear seat is not low when stored. It is in.

  In order to achieve the above object, in the present invention, the partition gate tilted backward is accommodated in the space on the bottom side of the loading platform portion of the double bottom structure.

  Specifically, the first invention includes a retractable rear seat, an upwardly open loading platform portion that forms a cargo compartment behind the passenger compartment, and a retractable partition gate that partitions the passenger compartment and the cargo compartment. Targeted vehicle rear structure.

And a gate accommodating portion for accommodating the partition gate. In addition, the partition gate is a first position that partitions the vehicle compartment and the cargo compartment, and is stored in the gate accommodation portion by falling backward from the first position, and the cargo compartment expands into the vehicle compartment. The lower end is pivotally supported so that the position can be switched.

  According to said structure, the loading platform part is made into the double bottom structure of a rear floor and a deck board. When the partition gate is in the first position, the passenger compartment and the cargo compartment are partitioned by the partition gate, and the luggage is placed on the deck board in the cargo compartment. On the other hand, when the partition gate falls to the rear side centering on the lower end portion and is set to the second position, the partition gate is stored in the deck accommodating portion of the rear floor and the deck board to store the deck board and the rear seat. The bottom surface of the cargo room that is enlarged in the passenger compartment is formed with the floor bottom surface generated in step (b). In this manner, the height of the bottom surface of the cargo compartment is the height of the deck board surface above the rear floor, regardless of whether the partition gate is in the first position or the second position.

  In the second invention, the rear seat includes a seat back and a seat cushion, the seat back is configured to be foldable, and a flat bottom surface of the cargo compartment is formed by the folded seat back and the deck board. And

A bottom surface is formed.

  In a third aspect of the invention, the partition gate accommodates a rear window glass that partitions the upper end of the partition gate and the roof so as to be raised and lowered when the partition gate is in the first position.

  According to the above configuration, when the partition gate is in the first position, the vehicle compartment and the cargo compartment are partitioned by the rear window glass and the partition gate, so that a rear view is secured. When rotating the partition gate to the second position, the rear window glass is inserted into the partition gate, and in this state, the partition gate is laid down on the rear side. As a result, the rear glass is also removed, there is no partition between the passenger compartment and the cargo compartment until reaching the roof portion, and the lengths of the partition gates housed in the gate housing portion are shortened. On the other hand, in order to accommodate the rear window glass in the partition gate, it is necessary to increase the thickness of the partition gate. However, since the partition gate is accommodated in the gate accommodating portion, the cargo space becomes narrow. There is nothing.

  In a fourth aspect of the invention, a deck cross member is coupled to the upper surface of the rear floor at the partitioning position between the vehicle compartment and the cargo compartment so as to extend in the vehicle width direction, and the partition gate is attached to the deck cross member.
