Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rear body structure of an automobile.

(Prior art) For example, so-called "one-box cars" such as cab-over type pan and wagon cars have traditionally had a standard roof type, middle roof type, high roof type, etc., even though they are of the same model. They are manufactured in different heights.

By the way, as shown in Japanese Utility Model Application Publication No. 63-74377, the rear roof of an automobile has conventionally been separated from the rear header, the roof rail, and the roof panel that covers the upper part of the rear header and the roof rail. has been done.

In such a configuration, for example, when constructing a high-roof vehicle, as schematically shown in FIG. Height of header 100 (especially inner panel height>
A structure is adopted in which the roof height 1-1 is increased by leaving I-it as the standard roof and changing only the height H3 of the upper roof panel 101 portion.

(Problem to be Solved by the Invention) However, with the above configuration, although the height of the roof itself is increased and the interior height can be increased,
Since the rear header 100 itself remains the same as the standard roof, the height of the upper edge of the rear opening (back door opening) (height of the frontage) I'' remains low, as can be seen from Figure 10. It became.

Therefore, even if a high-roof vehicle is constructed with a high ceiling and tall objects can be loaded inside, the low frontage may hinder loading and unloading operations. Ta.

(Means for Solving the Problems) The present invention has been made with the aim of solving the above-mentioned conventional problems, and it is possible to install a roof that is compatible with any of different types of roofs having different heights. In the rear body structure of an automobile configured to allow
The present invention is characterized in that a rear header of a roof of any height can be integrally joined to the roof rail and rear pillar.

(Function) According to the above-described rear body structure of an automobile of the present invention, the above-mentioned rear header is provided separately from the roof rail and the rear pillar, and when assembling the vehicle body, it is possible to select which of the plurality of rear headers having different heights. The structure is such that they can be joined and integrated in accordance with the set roof height of the vehicle.

Therefore, the height of the rear ladder changes depending on the height of the vehicle roof, such as a high-roof vehicle or a standard-roof vehicle, and the height of the upper edge of the back door opening can also be changed arbitrarily.

(Effects of the Invention) Therefore, according to the rear body structure of the automobile of the present invention,
For multiple car models with different roof heights, from standard roof cars to high roof cars, we have a back door with a frontage height that corresponds to the roof height of each car! 10, and the workability of cargo handling operations can be generally improved. Moreover, this structure can be realized without changing the heights of the roof rails and rear pillars, so it is advantageous in terms of cost.

(Example) FIGS. 1 to 9 show a rear body structure of an automobile according to an example of the present invention.

First, FIG. 8 shows the external configuration of a general one-box car 1. The one-box car 1 has three body spaces, for example, an engine room, a passenger compartment, and a trunk room, in a common body box (so-called one-box car). ). The one-box car 1 in this embodiment is configured by dividing the same body into at least two vehicle types, a standard roof type and a high roof type, each having a different roof height. ing.

That is, the rear header part 2 of the one-box car 1 is configured, for example, as shown in FIG. A rear header part 6 is optionally joined and integrated with the rear header part 6. There are two types of rear header parts 6, for example, a rear header 68 for a standard roof as shown in FIG. 2(a), and a rear header 6B for a no roof as shown in FIG. 2(b). It is protected.

First, the base body part 5 is shown in FIGS. 1 and 3, for example.
The first rear pillar inner panel 7 as shown in the figure
a and the first rear pillar outer panel 7b to form a closed cross-sectional structure; It consists of a second rear pillar part 8 extending from the lower end side to the upper roof site rail 9 part. The second rear pillar portion 8 connects a portion of the front edge of the rear pillar inner panel 7a of the first rear pillar portion 7 and a portion of the surface edge of the second rear pillar outer panel 8b. As shown in Figure 4, it is also constructed by extending upward to form a closed cross-section structure.
A roof sight rail 9 extending in the longitudinal direction of the vehicle body is joined to the outside of the upper second rear pillar inner panel 8a. The roof site rail 9 is also constructed by joining a roof site rail inner panel 9a and a roof side rail outer panel 9b facing each other in a closed cross-sectional structure.

As is clear from FIG. 1, for example, the upper end of the first rear pillar part 7 has a step for joining and fixing the rear header 6 (6A or 6B) in a fitted state on both the inner panel 7a side and the outer panel 7b side. Department (joint department) 10a, IOb
are formed on each outer surface.

Further, each of the rear edge portions lla and Ilb of the second rear pillar inner panel 8a and the second rear pillar outer panel 8b of the second rear pillar portion 8 extending upwardly extends, for example, as shown in FIG. The front edges 12a and 12b of the inner panel 6a and outer panel 6b of the header 6 (6A or 6B) are overlapped and joined to each other.

That is, the two types of rear headers 6A (see Fig. 2 (a)) and 6B (for standard roof and high roof) mentioned above are used.
In FIG. 2(b)), basically, a rear header inner panel 6a and a rear rudder outer panel 6b, both of which have a substantially U-shaped cross section, are opposed to each other and joined together to form a closed cross-sectional structure. First of all, the above figure 2 (
In the high roof version 6B shown in b), the corner portion 14 of the upper joint edge 16 of the rear rudder outer panel 6b is an inclined surface in the upward direction, and the rear roof panel 15 (see FIG. 9) is set to be higher by a predetermined dimension than the rear header 6A for a standard roof shown in FIG. 2(a) to correspond to a high roof vehicle. . As a result, a ceiling height l'[+ corresponding to a conventional high roof vehicle can be obtained. At the same time, the cross-sectional thickness of the rear header inner panel 6b forming the upper edge of the back door opening 20 is made smaller as shown in FIG. The vertical height H! ' (see Fig. 9) is made higher than the height H when the roof is standard. As a result, the conventional back door opening height H has been increased to correspond to the ceiling height H6 of high-roof vehicles.
It is possible to provide a high roof vehicle having a back door opening 20 higher than 2 and having high cargo handling efficiency.

On the other hand, the standard roof rear header 6 shown in Fig. 2(a)
In this case, the corner I4 of the rear rudder outer panel 6b does not have the above-mentioned inclined surface and is flat, and remains as it is on the front end side.

The cross-sectional thickness of the rear header inner panel 6a and the rear rudder outer panel 6b is also thick.

By the way, the reference numeral 17 designates a first reinforcement panel that extends from the second rear pillar part 8 side to the inside of the corner part 4 of the rear header 6 and is integrally joined to the rear header 6. The second reinforcement panel 18 installed and the bolt I at approximately the center of the corner part.
9 and 19 are integrally joined.

As a result, the mutually divided roof site rail 9, part of the rear pillar (7, 8), and part of the rear header 6 are strongly reinforced and integrated.
