Abstract

PURPOSE:To reduce the number of parts and man-hours for assembly by forming a cross-member for connecting front pillars in a box cross-section type closed structure, and also providing inlet and blowing ports of air conditioning air. CONSTITUTION:A cross-member 11 for connecting front pillars is formed in a box cross-section type closed structure, and air conditioning air inlet ports 15 and 17 and air blowing ports 16 and 18 are provided. Also fresh air is introduced from an air inlet port 31 in a dashboard 30, blown by a blower 32, led into the air inlet ports 15 and 17 through an air mixing damper 33, heater core 34, and ventilator damper 35, and introduced into the cross-member 11. Then the air is blown out from the blowing ports 16 and 18 to the inside of a cabin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioner,
Particularly, it relates to the structure of the ventilation duct.

[0002]

2. Description of the Related Art As an air conditioning system for vehicles, Japanese Utility Model Publication No. 63-29
Some are disclosed in Japanese Patent No. 636. In this air conditioner, the instrument portion supporting the lower edge of the windshield has a duct structure, and air is ejected toward the windshield and the interior of the vehicle. Further, recently, there is a tendency that the dimension of the instrument part in the front-rear direction becomes large, and there is an air conditioner having a structure shown in FIG. 6 in such a case. That is, the instrument panel 101
Driver side duct 1 for blowing air to the driver side inside
02, an assist side duct 103 for blowing air to the passenger seat side, a right side defroster duct 104 and a left side defroster duct 105 are respectively provided, and a ventilation duct is constituted by these dedicated parts.

[0003]

[Problems to be Solved by the Invention] Jitsuko Sho 63-2963
The air conditioner disclosed in Japanese Patent No. 6 cannot be applied to an instrument part having a large front-rear dimension. On the other hand, in the ventilation duct structure of the vehicle air conditioner shown in FIG. 6, the ventilation ducts 102, 103,
Since the components 104 and 105 are configured, the number of parts increases and the number of parts assembling steps increases.

[0004]

In order to solve the above problems, the present invention provides a cross member for connecting front pillars with a hermetically sealed structure having a substantially box-shaped cross section, and the cross member is provided with a blow-in air intake port. An air outlet was installed in the car.

[0005]

Since the cross member connecting the front pillars is used as a ventilation duct as a closed structure, the number of parts can be reduced and the number of assembling steps can be reduced.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a perspective view of a main part of a vehicle to which the vehicle air conditioner according to the present invention is applied, FIG. 2 is an exploded perspective view of the instrument part of FIG. 1, and FIG. 3 is a schematic cross-sectional view of the instrument part. 4 is a plan view of the cross member portion of FIG. 1, FIG.
FIG. 5 is a side sectional view taken along the line AA of FIG. 4.

An instrument panel 3 is provided on the instrument part 2 of the vehicle body 1, a windshield 4 (see FIG. 4) is provided on the front side of the instrument panel 3, and an instrument panel 3 is provided on the instrument panel 3. Part 5
Also, the instrument cover 6 and the like are attached.

A dashboard upper 7 is arranged inside the instrument panel 3. As shown in FIGS. 4 and 5, the dashboard upper 7 is a dash that also serves as a defroster duct and a cross member portion 11 that also serves as an outlet duct that serves as a cross member that connects between the front pillars 9 and 9 to which the front pillar extension 8 is fixed. The board upper portion 12 is integrally formed, and both end portions of the dashboard upper 7 and the front pillars 9 and 9 are welded using a spot sealer to enhance the sealing effect.

The cross member portion 11 has a hermetically sealed structure having a substantially box-shaped cross section, and as shown in FIG.
An intake port 15 for taking in the air blown out of the vehicle and four blowout ports 16 for taking out the taken-in air from the left and right sides and the central part are formed on the passenger side in the vehicle.

Similarly, the dashboard upper portion 12 is also formed in a hermetically sealed structure, and the intake port 17 for taking in the air blown out from the air conditioner body 14 and the four blown air taken out above the instrument part 2 are provided. The outlets 18 are formed respectively. Furthermore, these cross member parts 1
A blowout port 19 is also formed at a connecting portion between the vehicle 1 and the dashboard upper portion 12.

The instrument panel 3 has mounting holes 2 corresponding to the blowout ports 16, 18, and 19.
0, 21, 22 are formed respectively, and the outlet holes 23, 2 are respectively provided in the respective mounting holes 20, 21, 22.
4 and 25 are attached.

On the other hand, as shown in FIG. 3, the air conditioner body 14 blows the outside air taken in through the air intake 31 of the dashboard 30 or the inside air taken in through a duct (not shown) by the blower 32, and the air mix damper 33. According to the opening of the heater core 34 or mixed with the air passing through the heater core 34 to the cross member portion 11 according to the opening of the ventilator damper 35, and to the dashboard upper portion 12 according to the opening of the defroster damper 36. Blow each.

With the above-described structure, the air sent from the air conditioner body 14 is introduced from the air intake ports 15 and 17 of the cross member portion 11 and the dashboard upper portion 12 of the dashboard upper 7 serving as ventilation ducts. It is taken in, and each blow-out port 16, 18, through the cross member part 11 and the dashboard upper part 12,
It is blown into the car from 19.

Since the cross member portion 11 connecting the front pillars 9 and 9 is used as a ventilation duct as a hermetically sealed structure as described above, a dedicated ventilation duct is not required and the number of parts and the number of assembling steps are reduced. It becomes possible to obtain the vehicle body rigidity that cannot be obtained by the cross member between the conventional assembly type front pillars. Further, since the cross member portion 11 is integrally formed with the dashboard upper portion 12, it is possible to further reduce the number of assembling steps.

[0015]

As described above, according to the present invention,
Since the cross member connecting the front pillars is used as a ventilation duct as a closed structure, it is possible to reduce the number of parts and the number of assembling steps.
