As shown in fig. 5, the partition B3 has a plate surface extending in the front-rear direction so as to be joined to the reinforcement 27 and to partition a closed cross section (hollow portion) formed by the reinforcement 27 and the rear pillar outer 21 (see fig. 1) in the vertical direction.

As shown in fig. 1, the plural bulkheads B1, B2, and B3 are arranged such that the rear panel body 18 (see fig. 5) and the rear pillar inner 22 (see fig. 5) are positioned with respect to the door striker bracket 8 via the bent portion 4a formed in the door opening 6.

Action and Effect

The operational effects of the vehicle body side portion structure S of the present embodiment will be described below.

The vehicle body side portion structure S of the present embodiment includes a door striker bracket 8 that connects the rear wheel house 11 and the rear outer panel 2.

The vehicle body side structure S transmits a load input from the rear door at the time of door opening and closing and at the time of a side collision to the rear side panel 3 and the rear outer panel 2 forming the rear wheel house 11 via the door striker bracket 8. The vehicle body side portion structure S thereby improves the strength and rigidity with respect to the load input via the back door.

In addition, the vehicle body side portion structure S reinforces the closed cross section Cs of the rear side panel 3 and the rear outer panel 2 by the door striker bracket 8. This eliminates the need to provide a separate reinforcing member for the vehicle body side portion structure S, and allows these members that partition the closed cross section Cs to be used as framework members.

According to the vehicle body side portion structure S, it is possible to achieve both the fuel efficiency improvement by the weight reduction achieved by the compact structure and the improvement of the traffic safety by the strength and rigidity ensured at the time of a side collision

In the vehicle body side portion structure S, the support portion 32 of the door striker bracket 8 is sandwiched between the flange portion F1 of the rear outer panel 2 and the flange portion F2 of the rear side panel 3. The vehicle body side structure S can thereby more reliably reinforce the closed section Cs by the door striker bracket 8.

Specifically, the vehicle body side portion structure S can transmit the load at the time of opening and closing the door, which is easily input to the door opening portion 6, and the load input by the twisting of the vehicle body 1 to the rear panel 3 via the door striker bracket 8. According to the vehicle body side portion structure S, the strength and rigidity of the members partitioning the closed cross section Cs can be further improved without adding a reinforcing member such as a reinforcement.

In the vehicle body side portion structure S, the door striker bracket 8 includes the top portion 31 fastened to the door striker 7 via the rear outer panel 2, and the 3 rd leg portion 35 connecting the top portion 31 and the front wall W7 of the rear wheel house 11.

According to this vehicle body side portion structure S, the load input from the back door can be more efficiently transmitted to the rear side panel 3 and the rear outer panel 2.

In the vehicle body side portion structure S, the door striker bracket 8 is disposed so as to straddle the rear wheel house 11 and the damper housing 12.

According to this vehicle body side portion structure S, a load input from the rear door via the door striker bracket 8 can be dispersed and transmitted to the rear wheel house 11 and the damper housing 12, which are three-dimensional structural portions having high rigidity.

In addition, in the vehicle body side portion structure S, the rear pillar inner 22 has the bulkhead B1 at the upper end portion and the bulkhead B3 at the lower end portion.

That is, in this vehicle body side portion structure S, the upper portion of the rear pillar 4, which partially extends upward from the rear outer panel 2 and the rear side panel 3 reinforced by the door striker bracket 8 to form a closed cross section, is reinforced by the bulkheads B1, B3.

According to the vehicle body side portion structure S, the bulkheads B1, B3 and the door striker bracket 8 are interlocked with each other, whereby the closed cross section Cs formed by the rear outer panel main body 9 and the rear panel main body 18 and the closed cross section formed by the rear pillar outer 21 and the rear pillar inner 22 can be reinforced in an integrated manner.

In addition, in the vehicle body side portion structure S, the bent portion 4a is provided between the door striker bracket 8 and the bulkheads B1, B2, and B3.

The vehicle body side structure S thus efficiently transmits the load input from the rear door to the bent portion 4a via the door striker 7 to the rear panel main body 18 and the rear pillar inner 22 via the door striker bracket 8 and the bulkheads B1, B2, and B3.

According to the vehicle body side portion structure S as described above, the strength and rigidity of the bent portion 4a can be further improved.

In addition, according to this vehicle body side portion structure S, the transmission performance of the load input from the rear door to the rear side panel 3 side is improved by the reinforcing bent portion 4a. This can further improve the strength and rigidity of the door opening 6 and the constituent members of the closed cross section Cs in the vehicle body side portion without additionally adding a reinforcing member such as a reinforcement.

In addition, in the vehicle body side portion structure S, the insertion portion 26 of the rear pillar inner 22 has a bulkhead B2 (vertical bulkhead).

The vehicle body side portion structure S thereby improves the rigidity of the boundary portion between the rear pillar inner 22 and the roof side rail 5.

According to the vehicle body side portion structure S, the efficiency of load transmission from the rear pillar 4 to the roof side rail 5 can be improved. In addition, according to the vehicle body side portion structure S, the rigidity of the roof side rail 5 is also increased by the bulkhead B2, and the load transmitted from the rear pillar 4 to the roof side rail 5 can be efficiently dispersed.

In the vehicle body side portion structure S, the bulkhead B1 (bulkhead) is disposed at a position at least partially overlapping the line L of the lower end portion of the roof side rail 5.

According to the vehicle body side portion structure S, the rigidity of the boundary portion between the roof side rail 5 and the rear pillar 4, which is relatively easily deformed, can be ensured.

The present embodiment has been described above, but the present invention is not limited to the above embodiment, and can be implemented in various forms.
