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 British Patent No. 2086316,
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. A hood member is stretched between the rear edge of the passenger compartment and the rear edge of the vehicle compartment, and this hood member constitutes a rear roof, while a roof panel is constructed between the upper end of the front window and the collapsible pillar in the upright position. There is something I did. 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 vehicle interior. 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 effects for solving the problem) In order to achieve the above-mentioned purpose, in the present invention, the outside air release port is changed from the base vehicle by providing a collapsible pillar. It is constructed in the gap formed between the hood member and the rear deck. Specifically, the pillar has an inverted U shape and is installed between both side walls of the vehicle body, and is rotatable between an upright position and a tilted position stowed in the rear of the passenger compartment; a roof panel that can be opened and closed between the collapsible pillar and the upper end of the front window; and a roof panel that is installed between the collapsible pillar and a closed-section rear deck that is located on the rear side of the vehicle interior. a rear roof made of a canopy member; and an extractor chamber disposed in the interior space of the rear deck, the extractor chamber having an air intake port connected to the inside of the vehicle interior and an air discharge port connected to the outside of the vehicle interior. The air outlet is configured to communicate with a gap formed between the rear deck and the rear roof and 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 located in a part that is difficult to see from the outside of the car body, such as the gap between the rear deck and the rear roof, so there is no need to provide a separate grill. , which is preferable in terms of appearance and reduction of air resistance. In addition, this gap is a part that is created between parts that will inevitably be changed due to the additional (replacement) provision of a collapsible pillar, so in other words, it is an improvement made to the base vehicle. Since this is done by utilizing the ventilation structure of the base vehicle, there is no restriction 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 is stretched over.
As a result, car A, as shown in FIG.
A closed state in which the collapsible pillar 1 is in the upright position and the roof is stretched so that the rear part of the vehicle interior is covered by the canopy member 6 constituting the rear roof and the upper part of the vehicle interior is covered by the roof panel 5; From the closed state shown in the figure to the half-open state in which only the roof panel 5 is removed as shown in Fig. 2, and the upper and rear portions of the passenger compartment with the tilting pillar 1 in the tilted position as shown in Fig. 3. It is designed to be able to take on three states: a fully open state in which both are released, and a fully open state in which both 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 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 stretch the hood member 6 at a slightly rearward portion of the vehicle compartment, and the peripheral awning link 10 tensions the hood 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 respectively connect the collapsible pillar 1 and the double hood tension links 9 and 10, and perform the function of tensioning the hood member 6 near the left and right ends of the rear window glass 8. There is.

Now, let's move on to the fifth section regarding the ventilation structure of the passenger compartment.
This will be explained with reference to FIG.

First, the rear deck 12, which extends in the vehicle width direction and constitutes the peripheral edge of the rear end of the passenger compartment Y, is connected to the outer panel 12A.
and the inner panel 12B form a closed cross-sectional shape. A rain rail 13 extending in the vehicle width direction is connected to the lower end surface of this rear deck 12, and a halt 14,
Mounting hood member 16 fixed using nuts 15
The peripheral edge of the hood member 6 is coupled to the hood member 6 (this coupled portion is shown as α in FIG. 5).

An extractor chamber 17 is disposed in the space X within the rear deck 12 having the closed cross-sectional shape. The extractor chamber 17 is formed into a bag shape of plastic or the like, and has an air suction port 17a formed in its upper part and an air discharge port 17b formed in its lower part. This air suction port 17
a opens into a space X inside the rear deck 12, and this space X inside the rear deck 12 is connected to a communication port 19 formed in the inner panel 18 that constitutes the inner wall of the side wall of the vehicle body.
It is communicated with the vehicle body side wall inner space W via the space W. That is, the inner panel 18 cooperates with the rear fender panel 3 as an outer panel to form a side wall of the vehicle body with a closed cross section. Immediately behind, a communication port is formed that communicates the vehicle interior Y and the space W. In this way, the space X inside the rear deck 12 is communicated with the vehicle interior Y.

On the other hand, when the collapsible pillar 1 is in the upright position, a gap Z that is connected to the outside air is formed between the hood member 6 and the rear deck 12. 17b
is opened directly.

In addition, in the figure, 20 is a trunk lid, and V is a trunk room.

In the above configuration, in the closed state shown in FIG. ventilation with outside air. In addition, rainwater or the like from the gap Z is prevented from entering the vehicle interior Y by the trapping action of the extractor chamber 17.

(Effects of the invention) As is clear from the above, the invention has the following effects:
The opening of the ventilation passageway to the outside of the car body for ventilation of the car interior is made to open in the gap between the hood member and the rear deck, which is difficult to see from the outside of the car body. There is no need to decorate with decorations, etc., 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.
