Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle ventilation system installed in a hatchback type automobile in which a passenger compartment and a luggage compartment are connected to each other.

Conventionally, in this type of vehicle ventilation system, an indoor air vent hole is formed in the side finisher and rear pillar inner of a luggage compartment provided in the passenger compartment, and is communicated with the indoor air vent hole via a duct. Air exhaust holes were formed in a panel exposed to the outside, such as the rear fender. (Jitsukai 54-
(Refer to Publication No. 22746) However, such conventional vehicle ventilation systems have air exhaust holes in panels exposed to the outside, such as the rear fender, which makes them look unsightly. The problem was that the decorations had to be added, which was extremely time-consuming and wasteful.

Additionally, a duct that communicates the indoor air vent hole with the air discharge hole must be formed between the side finisher or rear pillar inner and the panel exposed to the outside, so the number of parts required to form the duct is small. There was a problem in that the production cost increased.

In addition, air vent holes are formed in the side finishers and rear pillar inner of the luggage compartment, which is connected to the passenger compartment, so that air blown from the instrument defroster toward the windshield can be routed through the ceiling and into the back door. Although it hits the glass, it does not follow the glass surface, but instead turns around and returns to the rear pillar side, where it is sucked into the interior air vent hole, making it difficult to clear the fog on the back door glass.

This invention was made by focusing on such conventional problems, and is an automobile in which a passenger compartment and a luggage compartment are connected to each other. The above problem is solved by providing a vent hole, interposing a partition plate between the rear panel and the rear finisher to form a duct, and communicating the duct with an air discharge hole formed in the rear combination lamp. It is an object.

The present invention will be explained below based on the drawings.

1 to 6 are diagrams showing one embodiment of the present invention.

First, to explain the configuration, reference numeral 1 in FIG.
This is a hatchback type automobile, and a luggage compartment 4 having a backdoor 3 is provided at the rear of a passenger compartment 2 of the automobile 1.

This luggage compartment 4 is formed by a rear panel 6 at the rear end of a floor panel 5, and rear fenders 7 raised up from both sides of the floor panel 5, which are joined by welding.

A rear finisher 8 made of synthetic resin and having both ends 8a, 8a bent at a substantially right angle is attached to a part of the rear panel 6 and rear fender 7, and covers the interior side of the luggage compartment 4.

Further, a side finisher 9 is attached to the rear fender 7 to cover the indoor side of the rear fender 7, and the rear fender 7 is connected to both ends 8a, 8a of the rear fender 8, respectively.

Further, a welt 9 with a weather strip is fitted to both upper edges 6b, 8b of the rear panel 6 and the rear finisher 8 where they meet.
Further, the lower portion 6c of the rear panel 6 and the lower edge 8c of the rear finisher 8 are integrally joined with clips 10.

Next, as shown in FIGS. 2 and 3, a bulge 11 is formed in the center of the rear finisher 8 and bulges toward the interior side. A lock attachment member 13 to which the lock portion 12 of the back lock device is attached is disposed within the bulge 11, and the upper edge 13a of the lock attachment member 13 is attached to the rear panel 6.
It is joined by welding to the upper edge 6b of.

Further, a striker 14 of a back door lock device attached to the back door 3 is located above the bulge 11 of the rear finisher 8 and the lock mounting member 13.
A hole 15 is provided for each passage.

Furthermore, as shown in FIGS. 2 and 4, in the upper part 8d of the rear finisher 8, on both sides partitioned by the bulge 11, a predetermined space is provided between the bulge 11 and each end 8a. Three air vent holes 16 are provided.

Further, on the surface of the rear finisher 8 facing the rear panel 6, horizontal ribs 17, which are partition plates extending to each end 8a, are integrally formed at upper positions on both sides partitioned by the bulge 11. .
The horizontal rib 17 forms a duct 18 by partitioning a space between the rear panel 6 and part of the rear fender 7 and the rear finisher 8 when the rear finisher 8 is attached to a part of the luggage compartment 4.

A seal body 19 made of urethane foam is interposed in a gap between the tip of the horizontal rib 17 forming the duct 18 and a portion of the rear panel 6 and rear fender 7.

Although the seal body 19 is attached to a portion of the rear panel 6 and rear fender 7 with an adhesive, it may be attached to the rear panel 6 and rear fender 7 using double-sided adhesive tape.

Furthermore, as shown in FIGS. 4 and 5, openings 2 are provided at each joint between the rear panel 6 and the rear fender 7.
0 is formed, and a rear combination lamp 21 is mounted inside facing the opening 20.

As shown in FIG. 5, a plurality of air discharge holes 22 are formed in the side portion 21' of the rear combination lamp 21 in a vertical arrangement.

Further, the rear combination lamp 21 is formed with a duct communication hole 21a. Therefore, the indoor air vent hole 16 and the air discharge hole 22 are communicated through the duct 18.

Furthermore, a removable lid 23 is attached to the bent portion of the rear finisher 8 for replacing the lamp of a rear combination lamp 21 attached to the rear panel 6 and rear fender 7. In the figure, 24 is the floor panel 5
This is a carpet laid on the floor.

Next, the action will be explained.

The wind blown from the instrument defroster toward the windshield passes through the ceiling and flows along the back door glass of the back door 3 while clearing the fog, and is sucked into the indoor air vent hole 16 located below the back door 3. .

Then, the air sucked into the indoor air vent hole 16 passes through the duct 18, passes through the duct communication hole 21a, and then passes through the side portion 21' of the rear combination lamp 21.
The air enters the inside of the vehicle and is discharged from the vehicle through the air discharge hole 22 of the rear combination lamp 21.

As explained above, according to this invention,
The structure is such that a hole for venting air in the interior is provided in the upper part of a rear finisher that covers the indoor side of the rear panel of an automobile in which a luggage compartment is provided in the passenger compartment, and a duct is formed by interposing a partition plate between the rear panel and the rear finisher. Since the duct communicates with the air exhaust hole formed on the side of the rear combination lamp that opens to the outside of the vehicle, the air exhaust hole appears as a decoration to the rear combination lamp, and is different from the conventional one. Compared to being provided alone, it provides a decorative effect and improves appearance.

In addition, this invention uses a rear finisher that covers the indoor side of the rear panel to form an indoor air vent hole, and uses the rear finisher and rear panel to interpose a partition plate between the rear panel and the rear finisher. Since a duct communicating with the punching hole is formed, the number of parts is reduced, assembly is easy, and manufacturing costs can be reduced.

Furthermore, since this invention has a hole for venting indoor air at the top of the rear finisher, the wind blows out from the instrument defroster toward the windshield, passes through the ceiling, and hits the back door glass of the back door. Since the air flows along the back door and is sucked directly into the indoor air vent hole located below the back door, there is no risk of the back door glass becoming foggy, and the effect of clearing the fog is achieved.
