Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the pillar structure of an automobile, and more specifically to the improvement of a rear pillar portion in which ducts are allowed to pass.

(Prior art) The rear pillar of an automobile is formed into a closed cross-sectional shape by an inner panel and an outer panel.Recently, air conditioning from an air conditioner installed in the rear trunk, such as ducts, is installed in such a rear pillar. It is equipped with ducts that guide wind into the cabin, as well as electrical wiring.

As shown in Japanese Utility Model Application Publication No. 59-143776, this type of rear pillar has a guide whose upper end is located on the roof side and opens forward, and whose lower end opens toward the rear approximately near the lower edge of the rear window. Some vehicles are equipped with a reinforcement, and this guide reinforcement not only reinforces the rear pillar but also guides the ducts so that they pass smoothly through the rear pillar.

(Problem to be solved by the invention) However, with the above-mentioned conventional method, it is necessary to separately provide a guide reinforcement to allow the ducts to pass smoothly, which is undesirable in terms of cost and weight reduction. Some kind of countermeasures are desired in this regard.

By the way, the uplifting load from the rear wheel suspension system acts on the rear wheel house.
In terms of strength, it is desirable that this thrust load be released as effectively as possible throughout the body without being concentrated locally.

Therefore, the purpose of this invention is to strengthen the rear pillar while taking into account the above-mentioned circumstances.
To provide a pillar structure for an automobile that allows a single reinforcement to effectively distribute the uplift load and facilitate work when arranging ducts through the rear pillar. It is in.

(Means and actions for solving the problems) In order to achieve the above-mentioned object, the present invention has the following configuration. That is, in an automobile having a rear pillar formed in a closed cross-section by an inner panel and an outer panel that are joined to each other above the rear wheel house, the rear pillar includes a rear pillar whose upper end is joined to the roof-side strength member and whose lower end is joined to the roof-side strength member. A reinforcement joined to the upper surface of the rear wheel house is disposed, the reinforcement is joined to the inner panel and cooperates with the inner panel to form a closed cross section, and the reinforcement On the rear wall of the lower end of the
An insertion opening for ducts passing through the closed cross section formed by the reinforcement is formed, and the duct is inserted from above at a position substantially corresponding to the insertion opening at the lower end of the reinforcement. A guide portion that guides the reinforcement toward the insertion opening is formed by cutting and raising the lower end of the reinforcement, and the guide portion is formed at an upper edge of the cut and raising opening that is formed by cutting and raising the guide portion. The pillar structure of an automobile is characterized by being located in the central part of the vehicle.

With this configuration, not only the rear pillar is reinforced, but the uplift load transmitted to the rear wheel house is transmitted to the roof side via the reinforcement and widely dispersed, resulting in favorable strength. .

In addition, when the ducts are inserted from above, that is, from the roof side, into the closed section formed by the reinforcement and the inner panel of the rear pillar, they are guided rearward by the guiding action of the guide part formed on the reinforcement. The ducts are guided and naturally led out of the reinforcement through the insertion opening opened in the rear wall of the reinforcement, making it easier to pass the ducts into the rear pillar. To explain this point in detail, first of all, the rear pillar is
It is usually located above the rear wheel house and slopes forward as it goes upwards. Therefore, the reinforcement inevitably extends almost perpendicularly upward from the upper surface of the rear wheel house, and then is bent in the middle to extend in a direction along the slope of the rear pillar. Therefore, if the ducts were simply inserted from the roof side into the closed section formed by the reinforcement, the ducts would go downward from the bent part of the reinforcement, but in the present invention, Due to the action of the guide part, it becomes possible to lead out rearward through the insertion hole.

Moreover, in this case, since the cut-and-raised opening is located at the upper edge of the cut-and-raised opening that is formed as a result of the cut-and-raised opening, the guide portion is formed at the lower edge of the cut-and-raised opening. There is no risk of the ducts coming out of the reinforcement through the cut-and-raised opening, and with the formation of the cut-and-raised guide section,
The guiding mechanism is not compromised.

(Example) An example of the present invention will be described below based on the attached drawings.

In FIG. 1, an automobile 1 has a rear pillar 4 between a side window 2 (rear auto window in the embodiment) located at the rearmost part and a rear window 3. As shown in FIG.

As shown in FIGS. 2 and 3, this rear pillar 4 has a closed cross-section shape by joining an inner panel 5 and an outer panel 6, and is sloped forward toward the front as it goes upward. ing. A rear wheel house 7 is formed in an extension extending downward from the inner panel 5.
A base end portion A of the rear pillar 4 is located above a substantially central portion of the rear wheel house in the front-rear direction.

A reinforcement 8 is disposed within the rear pillar 4, that is, within the closed cross section formed by the inner panel 6 and the outer panel 7.
This reinforcement 8 has its lower end joined to the upper surface of the rear wheel house 7, and its upper end is connected to the rear end of the roof rail 10, which serves as a strength member on the roof 9 side, that is, to a roof header (not shown). conjugated to the binding site. And reinforcement 8 is rear pillar 4
Due to the front slope of the rear wheel house 7, it once extends almost directly upward from the upper surface of the rear wheel house 7, and then is bent near the base end A (this bent part is indicated by the symbol B in FIG. 4).
It extends upward along the rear pillar 4.

The reinforcement 8 will be described in detail with reference to FIGS. 4 to 7. The reinforcement 8 has a substantially U-shaped cross section (see FIG. 7), and is joined to the inner panel 5. It cooperates with the inner panel 5 to form a closed cross section (see FIG. 3). The reinforcement 8, which has a closed cross section in this way, has a front wall 8A and a side wall 8B.
An insertion opening 11 is formed in the rear wall 8C, and a guide portion 12 is formed in the side wall 8B at a lower end thereof, that is, at a position slightly below the bent portion B. The insertion port 11 and the guide portion 12 are located at approximately the same height, and the guide portion 1
2 is formed into a plate shape by cutting and raising the side wall 8B. The guide portion 12 is slightly tilted back, that is, forms an inclined guide surface 12a that directs the member downward from the bent portion B toward the insertion opening 11.

The inner panel 5 and reinforcement 8
The space C (see FIG. 3) in the closed cross section formed by the above serves as a passage space for installing the ducts 13, and the upper end of the reinforcement 8 is connected to the roof rail 10. A forward facing opening 14 (see FIG. 6) is formed.

In the above configuration, in order to arrange the ducts 13 through the rear pillar 4, first, the rear end of the ducts 13 along the roof rail 10 is inserted into the space C in the reinforcement 8 through the opening 14. After inserting the ducts 13 into the ducts, the ducts 13 can be pushed in. As a result of this pushing, the rear ends of the ducts 13 eventually come into contact with the guide part 12, are changed backward by the inclined guide surface 12a of the guide part 12, and are guided out of the reinforcement 8 through the insertion opening 11. .

In this way, the ducts 13 are connected to the rear pillar 4.
The work of passing it inside is easily done.

On the other hand, the upward load from the rear wheel suspension system input to the rear wheel house 7 is effectively transmitted and dispersed to the roof 9 side by the reinforcement 8.

(Effects of the invention) As is clear from the above, the invention has the following effects:
By reinforcing the rear pillar, the uplift load input to the rear wheel house can be effectively transmitted and dispersed to the roof side, which is favorable in terms of strength. At the same time, the cut-up guide section allows the reinforcement to be used effectively as it is and has a guiding function for ducts passing through the rear pillar, so when ducts are installed through the rear pillar. can make the work easier.

Moreover, in this case, the guiding function is not impaired by the cut-and-raised opening formed when the guide portion is cut and raised.

Furthermore, since the guide portion is formed by cutting and bending, there is no need to separately provide a guide member, which is preferable from the viewpoint of cost and weight reduction.
