Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile body structure, and more particularly to a connection structure between a rear seat back support panel and a persiel at the rear of the vehicle body.

(Prior art) The conventional car body structure shown in Figs.
There is something like the one shown in the figure. That is, the vehicle compartment 10
1 and the inside of the trunk 102 are communicated through the opening 104 of the rear seat back support panel 103, as shown in FIG. The front edges are overlapped and joined together by spot welding or the like. Further, as shown in FIG. 5, a striker 106 is attached to the inclined rear seat back support panel 103 with bolts 107 and nuts 108.
By engaging and disengaging the rear seat bag 109 with a locking mechanism (not shown) built into the rear seat bag 109, the rear seat bag 109 can be locked in the illustrated upright position, or can be unlocked and laid down.

In addition, as a reference, Nissan Service Bulletin Showa
October 1958 No. 491 (BL-14) Introduction of the Bluebird U11 series car - There is a structure shown on page 4.

(Problems to be Solved by the Invention) However, in the conventional vehicle body structure described above, the joint between the rear seat back support panel 103 and the perciel 105 is in one place, which reduces the strength of the joint and the torsion of the vehicle. Rigidity and opening 10 in rear seat back support panel 103
4. Since the strength around the opening 104 is not sufficient depending on the structure, shape, etc. of the vehicle body, the opening 104 cannot be made very large. In particular, when the opening 104 is made larger, it is necessary to increase the area and plate thickness of the overlapping part between the rear seat back support panel 103 and the perciel 105, and therefore it is necessary to increase only the strength around the opening 104. Another problem is that the overall thickness of the rear seat back support panel 103 must be increased, resulting in a significant increase in overall weight.

Furthermore, it is difficult to attach the striker 106 to the inclined rear seat back support panel 103, and furthermore, when the rear seat back 109 is locked, the load applied to the striker 106 acts on the bolt 107 in the tensile direction. Not only is it easy to warm up, but the striker 10 of the rear seat back support panel 103
6. There was a problem that the strength of the mounting part had to be sufficiently increased.

This invention was made in view of these conventional problems, and its purpose is to reduce the overlap between the rear seat back support panel and the perciel without increasing the area or thickness of the overlap between the panels. The purpose of this invention is to significantly increase the joint strength of the vehicle body, the torsional rigidity of the vehicle body, and the strength around the opening of the rear seat back support panel.

(Means for Solving the Problems) In order to solve the above problems, in the present invention, the upper end portion of the rear seat back support panel and the front end portion of the persiel are overlapped and combined, and the rear seat back support panel A closed section is formed extending from the upper edge of the opening to the corner, and the side of the closed section is stepped downward to form a recess, and the side end is connected to the upper strut of the rear wheel house. It is characterized by being located close to the housing.

(Example) Hereinafter, an example of an automobile body structure according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a rear seat back support panel at the rear of the vehicle body, and the rear seat back support panel 1 is formed with an opening 2 that communicates a passenger compartment (not shown) with a trunk room (not shown). , the upper end thereof is bent into a step-like shape, and a mounting flange 1a is integrally formed therein. Further, the front end of the rear seat back support panel 1 has a central portion extending horizontally along the upper edge of the opening 2, and both side portions thereof are bent downward along the corners of the opening 2.

The front end of the persiel 3 is integrally connected to the upper end of the rear seat back support panel 1. That is, both sides of the parcel 3 are curved downward to form a recess 4, and the parcel 3
The front end of the mounting flange 3a is bent downward and attached to the mounting flange 3a.
The mounting flange 3a is fixed to the front surface of the upper end of the rear seat back support panel 1 by spot welding or the like, while the mounting flange 1a at the bent upper end of the rear seat back support panel 1 is fixed to the front surface of the upper end of the rear seat back support panel 1. The cross member 5 is fixed to the lower surface by spot welding or the like, and thereby a cross member 5 is formed at the upper end of the rear seat back support panel 1 as a box-like closed section extending in the transverse direction of the vehicle body. Therefore, this cross member 5 can significantly improve the bonding strength and the torsional rigidity of the vehicle body, and since the cross member 5 extends over the upper edge of the opening 2 and the corner portions on both sides thereof, the periphery of the opening 2 can be can significantly increase the strength of In particular, the upper side of the cross member 5 is stepped downward to form the recess 4, and the side end 5b of the cross member 5 is close to the strut housing 13 of the rear wheel house 12. By arranging the cross member 5 close to the highly rigid strut housing 13 in this manner, the vehicle body rigidity can be further increased.

A striker 7 for locking the rear seat bag 6 (see FIG. 2) in the upright position is attached to the upper surface of the stepped portion 5a of the cross member 5, and the mounting board 8 of the striker 7 and the cross member 5
The upper surface of the stepped portion 5a (i.e., the upper surface of Persiel 3)
is fixed by bolts 9 and nuts 10. A U-shaped locking member 11 is attached to the mounting board 8, and when the rear seat bag 6 is in the upright position shown in FIG. (not shown)
The rear seat bag 6 is held in the upright position by being locked. Since the striker 7 is thus attached to the upper surface of the stepped portion 5a of the cross member 5, the striker 7 can be attached from above, improving ease of assembly.

Since the striker 7 is thus attached to the horizontal upper surface of the cross member 5, which has a box-like closed section,
The mounting strength of the striker 5 can be increased, and the efficiency of the mounting work can also be improved.

Further, the recesses 4 formed on both sides of the parcel 3 behind the rear seat bag 6 can be effectively used as a storage space for small luggage and the like.

In this embodiment, the persiel 3 is formed by molding a single plate, but it may be formed into parts as appropriate depending on the situation. That is, the recess 4
It is also possible to form the shape etc. with a separate panel and then attach it to the Perciel 3 main body.

(Effects of the Invention) The automobile body structure according to the present invention has the above-described configuration and operation, and the box-shaped closed cross section formed by the end portion of the rear seat back support panel and the persiel improves the bonding strength of these panels and the vehicle body. The torsional rigidity of the rear seat back support panel can be significantly improved, and at the same time, the strength around the opening of the rear seat back support panel can be significantly increased. In particular, since the closed cross-sectional shape portion is located close to the strut housing, which is a rigid member,
It is possible to further improve vehicle body rigidity.

Furthermore, since the stepped portion is formed, a mechanical component such as a striker can be attached to the stepped portion from above, thereby improving ease of assembly.

Furthermore, the recess can also be used as a storage space, allowing effective use of space.
