Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quarter pillar for a vehicle, and more particularly to a quarter pillar structure for piping an air conditioning duct.

[0002]

2. Description of the Related Art In general, in a vehicle such as a wagon-type car, an air conditioner is also provided at a rear portion of a vehicle compartment and an instrument panel at a front portion of the vehicle compartment in order to maintain a wide room with a comfortable room temperature. There are air conditioners and air conditioners that air the vehicle interior. In this case, it is common practice to install an air conditioning duct in a gap between the quarter pillar and the roof side and a garnish that covers the quarter pillar and the roof side (Japanese Utility Model Laid-Open No. 2-43709).

As shown in FIGS. 3 and 4, an air conditioning unit 1 is installed in a quarter trim (not shown) that covers a side wall below a quarter window W at the rear of the vehicle compartment, and the air conditioning duct 2 is separated from the air conditioning unit 1. The air conditioning duct 2 is extended along the quarter pillar 3 and the roof side 40 of the passenger compartment, and the air conditioning duct 2 is covered with a garnish 7 (FIG. 4). I try to blow out the air.

[0004]

The air-conditioning duct 2 needs to have a large cross-sectional area in order to secure a sufficient air flow. However, if the cross-sectional area of the air-conditioning duct 2 is large, the garnish 7 covering the air-conditioning duct 2 projects to the quarter wind side, and the cabin space beside the rear occupant is restricted. Therefore, it is conceivable to form the interior of the quarter pillar in a concave shape and install an air conditioning duct along the interior, but the cross-sectional area of the quarter pillar is reduced and the strength is reduced. By increasing the thickness of the panel material constituting the quarter pillar, the strength and rigidity of the quarter pillar can be secured. However, in a vehicle such as a wagon-type vehicle, the inner panel that forms a closed cross section with the outer panel 31 is a rear end portion 41 along a pillar of the roof side inner panel 4 that forms a cabin wall around the quarter window.
In order to increase the thickness of the inner panel of the quarter pillar 3, the thickness of the entire roof side inner panel 4 is increased, which leads to an increase in the weight of the vehicle body. In FIG. 4, reference numeral 6 denotes a reinforcement that partitions the closed cross section of the quarter pillar 3, and B denotes a back door.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a quarter pillar structure for air conditioning duct piping that minimizes the restriction on the cabin space due to the installation of an air conditioning duct and secures the strength of the quarter pillar. It is a thing.

[0006]

According to the present invention, a quarter pillar having a closed cross section is constituted by an outer panel and a pillar portion at a rear end of a roof side inner panel which forms a cabin wall around a quarter wind. In a quarter pillar structure in which an air conditioning duct extending from the air conditioning unit installed in the building and extending to the roof side is piped in the gap between the quarter pillar and the garnish that covers it, the pillar is separated from the roof side inner panel. It consists of a thicker extension member, and connects the front edge of the extension member to the rear edge of the roof side inner panel, and connects the rear edge of the extension member to the rear edge of the outer panel to form a quarter pillar. And
Further, the extension member is formed in a cross-sectional shape in which the vehicle compartment side is concave, and the air conditioning duct is piped along the extension member. Since the inner panel of the quarter pillar is composed of a thick plate extension member separate from the roof side inner panel, the quarter pillar can have sufficient strength even if it is formed in a concave shape, and is large. Air-conditioning ducts with a cross-sectional area can be installed with less overhang to the quarter window side.

[0007] An intermediate portion of a reinforcement provided on the quarter pillar so as to partition a closed cross section thereof is connected to the extension member. Thereby, the strength of the quarter pillar can be further improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 3, an air conditioning unit 1 is provided in a space between a quarter panel and a quarter trim (not shown) which covers the quarter window W at the rear of the cabin of a wagon type vehicle. Is installed. An air-conditioning duct 2 is connected to the rear end of the air-conditioning unit 1. The air-conditioning duct 2 is piped along the quarter pillar 3 and extends along the roof side 40 of the passenger compartment. The air-conditioning duct 2 is provided with an outlet 21 near the front end along the roof side 40 toward the vehicle interior.

As shown in FIG. 1A, the quarter pillar 3 in which the air-conditioning duct 2 is provided has an outer panel 31, a roof side inner panel 4 (FIG. 1B), and a rear end 4 thereof.
2, and a closed cross-sectional structure composed of an extension member 5 that extends the roof side inner panel 4 rearward. A reinforcement 6 for reinforcing the quarter pillar 3 is provided inside the quarter pillar 3.

The outer panel 31 of the quarter pillar 3
Is formed integrally with a quarter panel forming the rear outer wall of the vehicle body. As shown in FIGS. 1 (A) and 1 (B), the roof side inner panel 4 is a panel material forming a cabin wall around the quarter window W, and a rear end portion 42 along the rear vertical edge of the quarter window W has an outer panel. 31 and the front edge of the reinforcement 6 are integrally welded.

An extension member 5 is welded along the rear edge of the roof side inner panel 4 along the rear edge. The rear end of the extension member 5 is integrally welded to the rear end of the outer panel 31 and the reinforcement 6. The plate thickness of the extension member 5 is greater than the roof side inner panel 4 and greater than the outer panel 31.

The entire quarter pillar 3 has a closed cross-sectional structure having an L-shaped cross section with a concave portion on the vehicle interior side, and the inside is partitioned inward and outward by a reinforcement 6. The air-conditioning duct 2 is installed in the recess 32 on the vehicle cabin side of the extension member 5 having an L-shaped cross section so that the outer side surface of the vehicle having the L-shaped cross section is along the extension member 5. The side surface of the air-conditioning duct 2 on the passenger compartment side is a gentle curved surface swelling toward the passenger compartment, and is covered with a garnish 7 along the curved surface. A seat belt anchor 8 is fastened to a rear position of the extension member 5. Seat belt anchor 8
The bolt member 81 protruding from the back surface is made to penetrate the garnish 7 via the cylindrical collar member 82 and is tightened to the weld nut 84 welded to the extension member 5 via the stay 83.

A quarter window glass W1 is provided in the opening of the quarter window W. The outer panel 31, the extension member 5, and the reinforcement 6 at the rear end of the quarter pillar 3 are provided with a sealing member B1.
Are attached so that when the back door B is closed, it comes into pressure contact with the inner peripheral surface of the back door B.

According to the above-mentioned quarter pillar structure, the inner panel of the quarter pillar 3 is substantially constituted by the thick extension member 5 connected to the rear edge of the roof side inner panel 4, so that the quarter pillar 3 is air-conditioned. Even if the cross-sectional area of the quarter pillar 3 is reduced by forming the concave portion 32 for piping the duct 2, the rigidity of the quarter pillar 3 can be sufficiently ensured. Further, since the extension member 5 is separate from the roof side inner panel 4, it can be easily processed into a concave shape having a large negative angle. Further, as compared with the conventional structure (FIG. 4), the increase in the plate thickness is only at the extension member 5 connected to the rear end of the roof side inner panel 4, so that the weight increase of the vehicle body can be minimized. Since the air-conditioning duct 2 is housed in the recess 32 of the extension member 5, even if the air-conditioning duct 2 has a large cross-sectional area, the air-conditioning duct 2 does not need to protrude toward the quarter window. Furthermore, the rigidity of the back door opening of the vehicle body can be enhanced by forming the inner panel of the quarter pillar 3 with the extension member 5 of a thick plate.

FIG. 2 shows another embodiment of the present invention. The reinforcement 6A provided on the quarter pillar 3 has a bulging portion 61 formed at an intermediate portion thereof to project toward the extension member 5, and the bulging portion 61 is overlapped with the intermediate portion of the extension member 5 and welded. I have. Other structures are substantially the same as those of the embodiment shown in FIG. 1, and the same parts are denoted by the same reference numerals.

By connecting the extension member 5 and the reinforcement 6A with a part of them and forming two closed cross sections between them, the mutual rigidity is enhanced, and therefore the rigidity of the entire quarter pillar 3 is increased. Can be strengthened.

[0017]

According to the quarter pillar structure for air-conditioning duct piping of the present invention, by increasing the thickness of a very limited portion of the vehicle body panel, the quarter pillar can be mounted on the vehicle interior without lowering its rigidity. A recess can be formed,
An air-conditioning duct having a large cross-sectional area and a small protrusion toward the quarter window side can be installed in the recess.
