Description

[Detailed description of the invention] (Field of industrial application) The present invention is a ventilation structure for an automobile that has a collapsible pillar that can be rotated between an upright position and a tilted position stored in the rear of the passenger compartment. It is related to.

(Prior Art) Some automobiles are of an open-top type that can cover the upper and rear portions of the passenger compartment and open the upper and rear portions of the passenger compartment as appropriate. Some of these open-top vehicles include, as shown in U.S. Patent No. 2,086,316,
The pillar has an inverted U-shape and is installed between the side walls of the vehicle body, and is rotatable so that it can take an upright position and a tilted position that can be stored in the rear of the passenger compartment. There is a vehicle in which a hood member is stretched between the vehicle and the rear edge of the vehicle interior, and a roof panel is constructed between the upper end of the front window and the collapsible pillar in the upright position. In other words, when the roof panel is installed between the collapsible pillar in the upright position and the upper end of the front window, the roof panel covers the upper part of the passenger compartment, and the rear part of the passenger compartment is covered by the hood member. On the other hand, if the collapsible pillars are set to the tilted position, the cover by the roof panel and hood member disappears, resulting in an open car with the upper and rear parts of the cabin open.

By the way, since the interior of a car is generally highly airtight, for this reason, as shown in Japanese Utility Model Application No. 58-134119, the outside air release opening of the ventilation passage connected to the interior of the vehicle is placed, for example, on the side of the rear pillar. The outside air release port is left open and is covered with a grill for an attractive appearance.

(Problems to be solved by the invention) Even in the case of an automobile having the above-mentioned collapsible pillars and roof panel, the airtightness of the cabin is higher than that of a car that covers the entire upper and rear part of the cabin with a canopy member. Therefore, it is necessary to ventilate the passenger compartment. When performing this ventilation, from the viewpoint of the appearance of the car and reducing air resistance, the outside air release port should not be opened on the surface of the car body that can be easily seen from the outside. It is desired to form this outside air release port without attaching anything.

In particular, this type of open-top vehicle is often constructed based on a vehicle with a fixed roof panel, with only the upper part being improved or changed. In other words, it is required to configure the outside air release port using parts that are changed (replaced), in other words, it is required to avoid placing restrictions on the ventilation structure of the base vehicle as much as possible.

Therefore, the purpose of the present invention is to respond to the above-mentioned requirements by devising the position of the outside air release port, so that the outside air release port can be hidden away from the surface of the vehicle by utilizing the upper structure of the automobile. An object of the present invention is to provide a ventilation structure for an automobile that can be formed in a location where the vehicle is ventilated.

(Means and actions for solving the problem) In order to solve the above-mentioned object, in the present invention, the outside air release port is configured in the gap formed between the collapsible pillar and the hood member. It's like this.
Specifically, the pillar has an inverted U-shape and is installed between both side walls of the vehicle body, and is rotatable so that it can take an upright position and a tilted position stored in the rear of the passenger compartment; a roof panel constructed to be openable and closable between the collapsible pillar in the upright position and the upper end of the front window; a hood member disposed between the collapsible pillar and the peripheral edge of the rear end of the vehicle compartment; an extractor chamber disposed in the interior space of the collapsible pillar; the extractor chamber has an air suction port connected to the interior of the vehicle; and an air discharge port connected to the outside of the vehicle; The structure is such that the structure communicates with a gap formed between the collapsible pillar and the canopy member and which is open to the outside air.

In this way, the part that serves as the outside air release opening to the outside of the car body is configured in a part that is difficult to see from the outside of the car body, such as the gap between the collapsible pillar and the hood member, so there is no need to provide a separate grill. Therefore, it is preferable in terms of appearance and reduction of air resistance. In addition, this gap is a part that is inevitably created by additionally (replacing) the collapsible pillar and top member, so in other words, it is possible to utilize the improved parts made to the base vehicle. Therefore, no restrictions are placed on the ventilation structure of the base vehicle.

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

In FIGS. 1 to 3, an automobile A is of a two-door type and includes an inverted U-shaped collapsible pillar 1. This collapsible pillar 1 is installed between both side walls of the vehicle body, and its left and right ends are rotatably attached to the vehicle body by pins 4 immediately behind the door 2, that is, at the front end of the rear fender panel 3. ing. As a result, the collapsible pillar 1 can take the upright position shown in FIGS. 1 and 2, that is, the position forming the rear pillar, and the tilted position shown in FIG. ing.

The upper part of the automobile A is constructed of a roof panel 5 and a hood member 6 using the collapsible pillar 1 described above. That is, the roof panel 5 is detachably attached between the collapsible pillar 1 in the upright position and the upper end of the front window 7, and the roof panel 5 is detachably attached between the collapsible pillar 1 and the rear peripheral edge of the passenger compartment. A canopy member 6 constituting a rear roof is stretched over the rear roof. As a result, car A:
As shown in FIG. 1, when the collapsible pillar 1 is in the upright position, the rear part of the passenger compartment is covered by the canopy member 6 which is stretched over the roof, and the upper part of the passenger compartment is covered by the roof panel 5, which is the closed state. , from the closed state shown in FIG. 1 to the half-open state with only the roof panel 5 removed as shown in FIG. It is designed to be able to take on three states: a fully open state in which both the front and rear parts are released. When the top member 6 is stretched as shown in FIGS. 1 and 2, rearward visibility is ensured through the rear window glass 8 provided on the top member 6.

Note that it is also possible to connect the collapsible pillar 1 and the roof panel 4 so that when the collapsible pillar 1 is in the tilted position, the roof panel 5 can be placed in the stowed state as shown in FIG. However, in this case, the half-open state shown in FIG. 2 cannot be achieved unless the roof panel 4 and the collapsible pillar 1 are disconnected from each other. In addition, the collapsible pillar 1
As shown in FIG. 4, the bracket 1A is fixed to the collapsible pillar 1 and is rotatably mounted on the wall surface of the vehicle body at a position slightly lower than the upper end of the rear fender panel 3. There is. Of course,
In order to achieve the half-open state shown in FIG. 2, a locking mechanism is provided to hold the collapsible pillar 1 in the upright position, but this locking mechanism may be eliminated so that the half-open state cannot be achieved.

The canopy member 6 is provided with a canopy tensioning mechanism so that it assumes a desired shape when the collapsible pillar 1 is in the upright position. This canopy mechanism includes an upper canopy link 9, a peripheral canopy link 10, and a pair of bands 11 located on the left and right sides of the rear window glass 8. That is, the two canopy links 9 and 10 are both U-shaped, and both ends thereof are rotatably attached to both side walls of the vehicle body. The peripheral awning link 10 serves to tension the canopy member 6 at a slightly rearward portion of the vehicle, and the peripheral awning link 10 tensions the canopy member 6 at a portion near the rear edge of the vehicle compartment so as to follow the shape of the rear edge of the vehicle compartment. It has the effect of establishing The pair of bands 11 connects the collapsible pillar 1 and the two-way hood tension links 9 and 10, respectively, and performs the function of tensioning the hood member 6 near the left and right ends of the rear window glass 8. ing.

The ventilation structure of the vehicle compartment will be explained with reference to FIGS. 5 and 6. The collapsible pillar 1 is configured with an outer panel 1B and an inner panel 1C in a closed cross-sectional shape over its entire length, and its internal space X,
More specifically, an extractor chamber 12 is disposed extending in the vertical direction in a space within the side end portion thereof that extends in the vertical direction in the upright position. The extractor chamber 12 is formed into a bag shape of plastic or the like, and has an air suction port 12a formed in its upper part and an air discharge port 12b formed in its lower part. This air suction port 12
a opens into the interior space X of the collapsible pillar 1, and this interior space X of the collapsible pillar 1 is communicated with the vehicle interior Y via a communication port 13 opened at the center of the inner panel 1C in the vehicle width direction. ing. Of course, this communication port 13 is
It is stylishly covered using the interior trim material 14 of the collapsible pillar 1.

On the other hand, a gap Z that communicates with the outside air is formed between the rear end of the collapsible pillar 1 and the hood member 6, and the air outlet 12b of the extractor chamber 12 is directly opened into this gap Z. There is. That is,
A canopy member 6 and a guide bracket 17 having a dual structure of inside and outside are connected to the rear end surface of the collapsible pillar 1 using bolts 15 and nuts 16. This guide bracket 17 extends rearward while being inclined, so that the portion of the hood member 6 near the joint to the collapsible pillar 1 is aligned with the guide bracket 17, so that at least the collapsible pillar 1 is in the upright position. The above-mentioned gap Z is formed when the position is .

Note that 18 in FIG. 6 is a side window.

In the above configuration, in the closed state shown in FIG.
2, it is communicated with the gap Z, that is, with the outside air, and ventilation with the outside air is performed. In addition, rainwater or the like from the gap Z is prevented from entering the vehicle compartment Y by the trapping action of the extractor chamber 12.

(Effects of the invention) As is clear from the above, the invention has the following effects:
The opening of the ventilation passage to the outside of the car body for ventilation of the passenger compartment is made to open in the gap between the collapsible pillar and the hood member that makes up the rear roof, which is difficult to see from the outside of the car body. There is no need to separately decorate the opening with a grill or the like, which is preferable in terms of reducing air resistance and making the exterior look neat and clean.

In addition, in this type of open-top vehicle, in which only the upper part of the vehicle body is often changed from the base vehicle, the vehicle interior can be ventilated without imposing any major restrictions on the ventilation structure of the base vehicle.
