(57) [Summary] [Object] The present invention improves the vertical rigidity of the upper back panel and the torsional rigidity of the body in the body structure around the lower part of the rear window of a passenger car, and improves the dimensional accuracy of the luggage opening. It is possible to provide a vehicle body structure in which the construction accuracy of the luggage door and the back window molding is improved and the construction accuracy is improved. [Structure] Between the upper back panel 1 and the inner support 3, one end is provided with an upper back panel 1 and a quarter panel 5.
And a reinforcing plate 6 which is connected to the roof side inner panel 4 and the other end of which is connected to the inner support 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle body structure around a rear window portion of a passenger car.

[0002]

[Prior art]

 The vehicle body structure around the lower part of the rear window of the passenger car, that is, the upper part of the luggage opening shown by the arrow B in FIG. 3 includes an upper back panel 1 and an upper back reinforcement 2 as shown in FIGS. The upper back panel 1, the quarter panel 5 and the roof side inner panel 4 are welded to each other to form a closed cross section, and the inner support 3 is connected to the upper back reinforcement 2 and the roof side inner panel 4. It has a welded structure.

[0003]

[Problems to be solved by the device]

 A hinge 7 of a luggage door is fixed in the vicinity of the closed cross-section structure portion of the upper back panel 1 and the upper back reinforcement 2, and the luggage door is pivotally attached to the hinge 7. When a vertical force F is applied to the upper back panel 1, a welding joint point a between the upper back panel 1, the quarter panel 5 and the roof side inner panel 4 and a welding joint point b between the roof side inner panel 4 and the inner support 3 are formed. The upper back panel 1 and the inner support 3 are deformed in the rotation direction around the center, and the vertical movement of the upper back panel 1 near the vehicle center increases. This has been a factor in poor installation of luggage doors and backwind malls.

An object of the present invention is to provide an automobile body structure that solves the above-mentioned conventional problems.

[0005]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is to form a closed cross section by an upper back panel 1 and an upper back reinforcement 2, and the upper back panel 1, the quarter panel 5, and the roof side inner panel 4 are In the vehicle body structure around the lower part of the rear window of the passenger vehicle, in which the inner support 3 is connected to the upper back reinforcement 2 and the roof side inner panel 4, the upper back panel 1 and the inner support 3 are connected to each other. A reinforcing plate 6 having one end connected to the upper back panel 1, the quarter panel 5 and the roof side inner panel 4 and the other end connected to the inner support 3 is interposed.

[0006]

[Action]

 With the above configuration, the vertical rigidity of the upper back panel 1 and the torsional rigidity of the body are improved, the dimensional accuracy of the luggage opening is secured, and the installation accuracy of the luggage door and the back window molding is improved.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is an upper back panel and 2 is an upper back reinforcement. The upper back panel 1 and the upper back reinforcement 2 form a closed cross section.

The upper back panel 1, the quarter panel 5 and the roof side inner panel 4 are joined by welding a, and the inner support 3 is joined by welding to the upper back reinforcement 2 and the roof side inner panel 4.

According to the present invention, a reinforcing plate 6 is interposed between the upper back panel 1 and the inner support 3, and one end of the reinforcing plate 6 is connected to the upper back panel 1, the quarter panel 5 and the roof side inner panel 4 by welding a. The other end is connected to the inner support 3 by welding c.

Since the present invention has the structure as described above, when the force F acts on the upper back panel 1 in the vertical direction due to the interposition of the reinforcing plate 6, the inner support 3 is welded to the roof side inner panel 4 by welding. Although the reinforcing plate 6 and the inner support 3 try to rotate about the point b in the direction of the weld joint point c, the reinforcing plate 6 pulls the upper back panel 1 from deformation.

As a result, the vertical rigidity of the upper back panel 1 and the torsional rigidity of the body are improved, the dimensional accuracy of the luggage opening is secured, and the building accuracy of the luggage door and the back window molding is improved. is there.

[0012]

[Effect of device]

 As described above, according to the present invention, one end is connected to the upper back panel 1, the quarter panel 5 and the roof side inner panel 4 between the upper back panel 1 and the inner support 3, and the other end is connected to the inner support 3. Since the reinforcing plate 6 is connected, the upper back panel 1 and the roof side inner panel 4 are firmly connected to each other, and the vertical rigidity of the upper back panel 1 and the torsional rigidity of the body are improved. This has the advantage of ensuring the dimensional accuracy of the luggage opening and improving the installation accuracy of the luggage door and back window molding.
