Abstract

PURPOSE:To assure a function of trunking through and prevent the torsion of a strut, by fitting a shelf panel with a support to form a quadrangular vertical section. CONSTITUTION:A seat back side panel 11 comprises a flange 33 coupled to a rear fender inner panel 27, a main surface 37 welded at S1 on the front surface 7a of the main part 13 of a strut 7 and on a front panel surface 35 bent from a side panel 23, a horizontal surface 39 welded at S2 on the upper support surface 17 of the strut, and a vertical surface 41 welded at S3 on the side panel 23 and a main panel 21. A support 43 is composed of the horizontal surface 39 and the vertical surface 41 of the seat back side panel 11.

Description

[Detailed description of the invention] This invention provides four improvements to the WJ construction of automobile bodies.

Generally, the rear tire house is equipped with a strut tower that supports the rear suspension. A shelf panel 105 is provided that connects the seat back side panel 101 that supports the bag (not shown) in an upright position and the inner panel 103 (opposite side not shown) of the A7 fender. Side panel section 104 and sea j.
The upper end of the backside panel 101 is joined together. On the other hand, the strut tower 107 erected in the tire house 106 is made in the shape of a peripheral wall 113 suspended around an upper support surface 111 on which the A7 suspension 109 is attached. It has a rectangular cylindrical structure that easily causes twisting deformation in relation to the cargo unit.

If the strut tower 107 undergoes torsional deformation, the steering stability during driving will deteriorate and a squeaking sound will occur. We are taking measures that combine these. However, the rigidity was still insufficient because only the flange portion 115 connected to the inner panel 103 of the strut tower 107 could bear the force against the torsional deformation (arrow A) of the strut tower 107. In order to solve this lack of rigidity, for example, as shown in Fig.
The connecting portion a of the shelf panel 105 such as the seat back side panel 101 extending inward from the rat tower 107 is supported by the V strut 117, and
7 is fixed to the floor panel 119 via a bracket '120, but with this structure,
While it is possible to ensure rigidity by exerting sufficient tension against torsional deformation of the strut tower 117, for example, trunk-through type vehicle models that connect the passenger compartment and rear trunk compartment by folding down the rear seat In this case, there was a new problem in that the V strut 117 became an obstacle.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vehicle body structure that can prevent torsional deformation of the slat tower while ensuring the function as a trunk through-hole.

In order to achieve this object, the present invention includes a shelf panel that is also provided on the back of the rear seat and connects the rear fender inner panels on both sides of the vehicle body, and a main body of the strut tower that supports the rear fender inner panel. In a single-room rear structure consisting of a seat back side panel to be joined, the seat back side panel, a strut tower, and a shelf panel are integrally joined to the back side of the shelf panel, and there is a space between the shelf panel and the seat back side panel. The gist of this is that a support member having a box-like vertical cross section is provided.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings from FIG. 5 to FIG. 9. In Fig. 5, reference numeral 1 indicates a trunk-through type rear seat.The seat 1 is a known type consisting of a seat cushion 3 and a seat back 5, and a part of the seat back 5 is made so that it can be folded forward. ing. FIG. 6 shows the vehicle body structure around the strut tower 7 with the rear seat 1 removed, with reference numeral 9 indicating a shelf panel and 11 indicating a seat back side panel.

The main body part 13 of the stock 1-tower 7 is the tire house 1
It is formed into a rectangular tube shape rising from 5, and the main body El
A beam A7 Lisbenshi 1in 19 is supported on the support surface 17 of +13. - The shelf panel 9 is formed of the main panel section 21 of the medium heat section and the υ' side panel section 23 connected to both ends of the main panel section 21, and the flange 25 of the side panel section 23 is connected to the rear fender inner panel 27. The flange 29 of the main panel section 21 is connected to the beam 1 to the panel 31, respectively.

The seat back side panel 11 has a flange portion 33 connected to the A/F T inner panel 27 on the right side, and a front peripheral wall surface 7a of the main body portion 13 of the stock 1 to tower 7.
and a front panel surface 35 bent from the side panel portion 23
It has a main body surface 37 which is integrally welded to S1, and a horizontal surface 39 which extends from the main surface 37 and is welded S2 to the upper support surface 17 of the strut tower 7;
The three horizontal surfaces extending from the sea 1 to the back side panels 11 and the vertical surface 41 that rises upward and spans the back side of the side panel section 23 and the main panel section 21 and are fixed by welding @S3. The surface 41 constitutes a support member 43, and the shelf panel 9 and this support member 4
3. J: Forms a box-like vertical section. Therefore, the main body 81i 13 (,r, seat back side panel 1
1 and a shelf panel 9 are coupled and supported.

Therefore, according to the vehicle body groove) Δ of this embodiment, beams are provided in the stock 1 to tower 7, and due to the load that is not transmitted to the stock 1 to tower 7 and the imaging during driving, the stock 1 ~ Even if the tower 7 tries to cause torsional deformation, the support member 43 having a box-like vertical cross section will suppress the torsional deformation of the strut tower 7, and the squeak noise and deterioration in maneuverability caused by the torsional deformation will no longer occur. Since there are no obstacles between the passenger compartment and the rear trunk, this function is effective in trunk-through type vehicles.

10 to 13 show another embodiment of a support member 43 having a box-like vertical section. The seat back side panel 11 of this embodiment extends the main surface 37 of the panel 11 upward to constitute the side panel portion 23 of the shelf panel 9 in the embodiment described above, and extends to the outer flange 45 beam 7. The inner end is connected to the inner panel 27 of the fender and the main panel part 21 of the shelf panel 9, respectively. And the main part 1 of Stocks 1 to Ku-7
The three parts of the third seam 1 to back side panel 11 and shelf panel 9 are the first flange 47, the second flange 49, and the third
They are integrally coupled and supported by a support member 43 having a flange 51. That is, the first flange 47 of the support member 43 is attached to the side circumferential wall surface 7b of the main body portion 13 of the stock 1 to tower 7, the second flange 49 is attached to the back side of the shelf panel 9, and the third flange 51 is attached to the shelf panel 9. More curved front panel surface 55 and sea 1 to back side panel 1
Shelf panel 9 is connected along 28 to one side 47 of 1.
and the support part vI 43 form a box shape in vertical section.

Therefore, in this embodiment as well, the torsional deformation of the strut tower 7 can be suppressed by the support member 43 as in the previous embodiment, and creaking noise and deterioration in maneuverability will not occur. Further, as in the first embodiment, it is possible to eliminate obstacles between the vehicle interior and the rear trunk, so that it can function effectively even in a trunk-through type.

As explained above, according to the vehicle body structure of the present invention, it is possible to suppress torsional deformation of the strut tower, which reduces unpleasant squeaking noises and improves steering stability. 11 can be improved. In addition, it has the practical effect of functioning effectively even in trunk-through type vehicles.
