Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the body structure of the lower quarter of an automobile.

[Prior art]

FIGS. 7 to 10 show the structure of a conventional lower part of a quarter. On both sides of the luggage room 12, the upper end of the quarter panel 1 is joined to the upper end of the roof side inner panel 8, and the lower end of the quarter panel 1 is connected to the rear floor side panel 6.
It is attached to the bottom end of the.

The upper end of the rear floor side panel 6 is joined to the rear floor 5. The lower end of the extension panel 4 is joined in advance to the upper end of the rear floor side panel 6, and the lower end of the roof side inner panel 8 is joined to the upper end thereof. The wheel house consists of a wheel house outer panel 2 and a wheel house inner panel 3, which are joined by a flange along the upper edge of the arch. The edges are joined. As shown in FIG. 9, a closed section A is formed between the rear part of the roof side inner panel 8 and the quarter panel 1 by the panels 1 and 8, the rear floor side panel 6, and the extension panel 4. There is.

A sealer 9 is applied to the lower end joints of the quarter panel 1 and rear floor side panel 6 along the joint line.
has been applied.

If the extension panel 4 has a structure in which the roof side inner panel 8 is extended downward and connected directly to the rear floor side panel 6, welding must be performed within the closed section A.
Since the work is difficult, it is welded to the rear floor side panel 6 in advance, and its upper end and the lower end of the roof side inner panel 8 are welded from the indoor side. Further, the sealer 9 is applied in order to completely seal the joint of the quarter skirt portion against water splashing from the tire.

[Problems that this proposal seeks to solve]

By the way, in the above-mentioned conventional structure, when applying the sealer 9 on the closed cross section A shown in FIG. 9, it is difficult to visually see the applied area, and the application tends to be uneven such as being deviated from the joining line, resulting in incomplete sealing. There was a fear that this would happen.

Further, general requirements for vehicle body structures include reducing the number of parts to reduce cost and weight without reducing strength, and improving workability by reducing welding points. In this sense, it is desirable to abolish the extension panel 4.

Therefore, the present invention provides a quarter lower structure that simplifies the structure by eliminating the extension panel 4, has excellent strength, and allows sealer application to be performed easily and reliably. The purpose is to solve problems.

[Means for solving problems]

As shown in FIG. 2, the roof side inner panel 8 and the wheel house outer panel 2 are constructed from a single plate to form an integrally molded body. Then, as shown in FIGS. 2 and 5, the roof side inner panel 8
A rear floor side member 6 whose rear lower end 8a extends to the lower end position of the quarter panel 1, where the lower end 8a is joined to the lower end of the quarter panel 1 and the lower end of the rear floor side panel 6, and whose upper end is connected to the rear floor 5 is connected to the vehicle. A V-shaped space 10 is formed above the sealer 9 application part by tilting toward the indoor direction.

[Effect]

By forming the roof side inner panel 8 and the wheel house outer panel 2 with a single plate, and having a structure in which the lower end of the roof side inner panel 8 and the lower end of the quarter panel 1 are directly joined,
The conventional extension panel 4 can be abolished, and the welding between the roof side inner panel 8 and the wheel house and the welding between the extension panel 4 and the rear floor side panel 6 and the roof side inner panel 8 can be omitted.

Furthermore, since the V-shaped open space 10 is formed above the sealer application section, the sealer can be applied easily and reliably. Furthermore, by integrating the wheel house outer panel 2 and the roof side inner panel 8, the supporting rigidity of the quarter panel 1 can be improved.

〔Example〕

The present invention will be explained with reference to the embodiments shown in FIGS. 1 to 6, focusing on the differences from the conventional structure.

As shown in FIGS. 1 to 4, and particularly in FIG. 2, the roof side inner panel 8 and the wheel house outer panel 2 are constructed of a single plate integrally molded. As shown in FIGS. 1, 3, and 4, a wheel house inner panel 3 is welded to the inner surface of the arch of the wheel house outer panel 2.

Quarter panel 1 forming the outer surface of the rear of the vehicle
The upper ends of the roof side inner panels 8 are welded to the upper ends of the roof side inner panels 8 on both sides of the luggage room 12, and the lower edges of the parts covering the wheel houses are welded to the arched outer edges of the wheel house outer panels 2. Above roof side inner panel 8
The lower end 8a extends to the lower end position of the quarter panel 1 at the rear of the wheel house, and the lower end 8a extends to the lower end of the quarter panel 1 along with the lower end of the rear floor side panel 6.
It is welded to the bottom end of the.

The rear floor side panel 6 is slanted upward toward the interior of the vehicle, and its upper end is connected to the rear floor panel 5.
It is welded to the side edge of the As a result, as shown in FIG. 5, the roof side inner panel 8 is composed of a single plate up to the skirt flange assembly at the lower part of the quarter, and forms a closed section B with the quarter panel 1.

On the other hand, the rear floor side panel 6 forming an inclined surface
As shown in FIGS. 5 and 6, a space 10 having a V-shaped cross section extending back and forth is formed between the roof side inner panel 8 and the quarter panel 1 at the rear of the roof side inner panel 8. do. A sealer 9 is applied along the panel joining line at the bottom of the V-shaped space 10.

As explained above, in the present invention, the roof side inner panel 8 and the wheel house outer panel 2
In addition, the panel 8 is extended to the lower end of the quarter panel 1 and connected to it, so the conventional extension panel 4 is omitted, the number of welding points is reduced, and the welding work itself is simplified. becomes easier. Furthermore, since a V-shaped space with an open top is formed between the extension of the roof side inner panel 8 and the rear floor side panel 6, the sealer 9 can be easily applied along the lower edge of the quarter skirt. can be applied to the proper position without any variation, and perfect sealing performance can be achieved. Moreover, since the roof side inner panel 8 is constructed from a single plate from the upper part of the quarter to the lower part, the supporting rigidity of the quarter part is strengthened. Furthermore, since the roof side inner panel 8 and the wheel house outer panel 2 are made into a single plate, and the wheel house inner panel 3 is welded to this,
The welding work is easier than conventional three-ply welding, and the sealing properties of the welded parts are also good.
