Abstract

PURPOSE:To prevent the pollution and the like inside a trank room caused by dust and the like mixed in indoor air by conducting the indoor air exhausted from an exhaust port on the rear end of a parcel shelf in the rear side of a seat to the outside of a car through a duct provided in a trank room part. CONSTITUTION:The indoor air exhausted from an exhaust port 11 provided in the rear end part of a parcel shelf in the rear side of a seat A is conducted to the outside of a car. In this case, a lateral air duct 4 extended in the direction of the width of the car is provided between a seat-back trim 2 and an innermost-wall trim 3 of a trank room 13. An emboss part 18 is provided on a part of a parcel panel 14 with its upper space connected to the exhaust port 11 and an air-hole 19 on its underside. Meanwhile, a side air-duct 7 extended to the front and the rear of the car is provided between an car body panel 5 and a side trim 6 of a trank room 13, while a duct 71 is provided behind to be connected to an external exhaust port 8. This construction permits to exhaust the above- said indoor air to the outside of the car without passing through the trank room 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation structure for an automobile that guides indoor air discharged from an indoor air outlet provided at the rear end of a parcel shelf behind the seat to the outside of the vehicle.

An example of a conventional automobile ventilation structure is shown in FIG.

That is, the parcel shelf (1) behind the seat (5)
An indoor air outlet Uυ is provided at the rear end, and this indoor air outlet Uυ communicates with the trunk room 0 from within the reinforcement U cross section.
An exhaust port to the outside of the vehicle is provided, and the indoor air is exhausted to the outside of the vehicle after passing through the trunk room (1"5).

However, in such a conventional automobile exhaust structure, the indoor air always passes through the trunk room (I31), so the dust, moisture, etc. carried when the indoor air moves flows into the trunk room (I31), (There was a problem that the inside of the 137 could get dirty or wet, causing damage to luggage and parts.

For this reason, some models are equipped with a special duct to prevent them from passing through the trunk, but this is not easy to adopt as the number of parts increases and the structure becomes complex, which increases manufacturing and assembly costs. There wasn't.

The present invention was made in view of these conventional problems, and an object of the present invention is to provide an automobile ventilation structure that guides indoor air to the outside of the vehicle without passing through the trunk and that can be easily formed. It is said that

In order to achieve such an object, the present invention provides a ventilation structure for an automobile that guides indoor air discharged from an indoor air outlet provided at the rear end of a parcel shelf behind the seat to the outside of the vehicle. A lateral air guide path extending in the width direction of the vehicle body is formed between the rear wall trim and the upper part of the lateral air guide path to communicate with the indoor air outlet to guide indoor air, and the trunk room side wall trim and the vehicle body panel 11 A rear exterior exhaust port 1' extending in the longitudinal direction of the vehicle body,
Diagnose the side air guide path with which ′ is connected, and this side air guide a
□Part □8, Air guide path.・-1-yo. K 111 section is connected to the side air guide duct, and the air guided to the side air guide duct is guided to the outside exhaust port and discharged outside the vehicle, so that the indoor air can be exhausted outside the vehicle without passing through the trunk room. This is what I did.

The present invention will be explained below based on illustrated embodiments.

Note that the same parts as in the conventional example are given the same reference numerals.

2 to 6 show an embodiment of the present invention. In the parcel shelf (1) behind the sheet (5), parcel l-IJ powder is placed on the parcel panel I, An air outlet αυ is provided in the parcel molding U61 fitted to the rear outer periphery of the parcel trim U.

The rear part of the parcel panel I forms the vehicle body strength member, and the wind panel αD is glued to it, and behind it forms the opening of the trunk room (13i), and the rain force from below is applied to the parcel panel α4. It is reinforced to form the rear upper part of the trunk room (131), but the closed section formed by the reinforcement (1) and the parcel panel (14) does not communicate with the air outlet Uυ:
1°. Then, a part of the parcel panel (14) falls downward 111:.

The embossed part (1gI is formed, the embossed part uQ
The upper space of the room is connected to the indoor air outlet, and the lower surface has an air guide hole.

The front end of the parcel shelf (1) is close to the sheet
Flange a located near the front end of the parcel panel (14)
A seat back trim (2) is passed between the seat back trim (2) and the floor (fB) to partition the vehicle interior and the space behind it. The seat back trim (2) is the seat back support (2υ
and place seat back support (the lower part is supported by 2 pieces).

The back wall trim (3) of the trunk Q31 that partitions the space between the ventilation hole (Ll and the trunk compartment 0) is attached to the mounting bracket 6 whose upper end is fixed to the underside of the parcel panel I.
With υ, the lower end is fixed by the mounting bracket 03 fixed to the floor tBl, and a lateral air guide path (4) extending in the vehicle width direction is formed between this back wall trim (3) and the seat back trim (2). has been done.

As shown in Figures 5 and 6, trunk room Q3
A side trim (6) that partitions the vehicle body panel (5) and the trunk room u3 is attached to the upper and lower mounting brackets 6υ on the side of i.
The side air guide path (7) is fixed by the side trim (6) and the vehicle body panel (5) and extends in the longitudinal direction of the vehicle body.
) is formed at the rear of this side air guide path (7), and a duct (7υ opens to the outside of the side air guide path (force), and this duct σ
υ communicates with an exterior exhaust port (8) formed in the shape of a slit hole.

Then, the side air guide path (the front part of the force and the side part of the side air guide path (4) are connected at the side of the vehicle body, and continues from the indoor air exhaust port (8) to the outside exhaust port (8). forming a passage.

In the exhaust structure of an automobile having the above configuration, indoor air is discharged from the indoor air outlet αυ at the rear end of the vehicle interior to the space above the embossed part of the parcel panel I outside the vehicle interior, and from there, the air is It flows into the horizontal air guide path (4) through the hole u9. Indoor air moves in the width direction within the lateral air guide duct (4) and reaches the side of the car body, and from there changes direction and enters the side air guide duct (4) and moves in the longitudinal direction of the car body. Tact (71),
It is discharged to the outside of the vehicle from the exterior exhaust port (8).

According to the ventilation structure for an automobile according to the present invention, since the air guide path is formed by the trim and the vehicle body panel without using a dedicated duct, it is possible to create a ventilation structure with a simple structure that does not allow passage through the trunk room. When the indoor air is discharged, the trunk compartment is not soiled or wet, and there is no increase in cost.

Although it goes without saying that the embossed portion formed on the parcel panel is not necessarily necessary, if the embossed portion is formed, it can contribute to improving the strength and rigidity of the parcel shelf and, ultimately, the vehicle body.
