Abstract

A vehicle air conditioning device comprises an instrument panel, a door that includes an overlapping portion where part of the door overlaps with the instrument panel in a closed state of the door, and a door blower outlet that opens toward a vehicle cabin interior, a first opening that is open toward the door, a second opening that is open toward the instrument panel, an air conditioning unit body, a first duct that that has a length direction end portion connected to the first opening, a second duct that has a length direction end portion connected to the door blower outlet, and a fin member respectively provided at the first opening and the second opening.

First claim

What is claimed is:

1 . A vehicle air conditioning device comprising:
an instrument panel that is provided at a front side of a vehicle cabin; a door that is provided at a vehicle width direction outer side of the instrument panel so as to be capable of opening and closing, and that includes an overlapping portion where part of the door overlaps with the instrument panel in a closed state of the door, and a door blower outlet that opens toward a vehicle cabin interior; a first opening that is provided at the instrument panel at a location corresponding to the overlapping portion of the door and that is open toward the door; a second opening that is provided at the overlapping portion of the door at a location corresponding to the first opening and that is open toward the instrument panel; an air conditioning unit body that is provided inside the instrument panel and that supplies air through a blower outlet; a first duct that is formed in a tube shape, that has one length direction end portion connected to the blower outlet, and that has another length direction end portion connected to the first opening; a second duct that is formed in a tube shape, that has one length direction end portion connected to the second opening, and that has another length direction end portion connected to the door blower outlet; and a fin member respectively provided at the first opening and the second opening to place the first opening and the second opening in a closed state when the door is open, and to place the first opening and the second opening in an open state when the door is closed.

2 . The vehicle air conditioning device of claim 1 , wherein:
the fin member is axially supported by a fin shaft with an axial direction running along a width direction of the first opening or the second opening; the fin member is inclined toward a vehicle vertical direction around the fin shaft by a link mechanism when the door is open so as to place the first opening or the second opening in the closed state; and the fin member is swung around the fin shaft by the link mechanism when the door is closed so as to lie substantially horizontal and place the first opening or the second opening in the open state.

3 . The vehicle air conditioning device of claim 2 , wherein the link mechanism is connected to a location that is displaced during opening and closing of the door.

4 . The vehicle air conditioning device of claim 1 , wherein a seal member is respectively provided at a peripheral edge of the first opening and a peripheral edge of the second opening.

5 . The vehicle air conditioning device of claim 2 , wherein a seal member is respectively provided at a peripheral edge of the first opening and a peripheral edge of the second opening.

6 . The vehicle air conditioning device of claim 5 , wherein:
the seal member includes a hollow portion therein; and at least a portion of the link mechanism is accommodated inside the hollow portion.

7 . The vehicle air conditioning device of claim 4 , wherein an opening side end portion of each seal member is joined to at least one of the corresponding peripheral edge or a member attached to the peripheral edge.

8 . The vehicle air conditioning device of claim 2 , wherein:
the fin member is configured by a plurality of fins; and the link mechanism includes:
a coupling rod that is disposed further toward an inside of the first duct or the second duct than the fin shaft, and that axially supports and couples together the plurality of fins,
a door opening-closing coordination rod that extends along the vehicle width direction at a peripheral edge of the first opening or the second opening, and that includes a fin abutting portion configured to abut at least one fin among the plurality of fins inside of the first duct or the second duct in at least the open state,
a first biasing member configured to apply a biasing force to the coupling rod in a direction to transmit the biasing force to the plurality of fins, and
a second biasing member configured to apply a biasing force to the door opening-closing coordination rod in a direction from the inside toward an outside of the first duct or the second duct.

9 . The vehicle air conditioning device of claim 8 , further comprising:
a frame-shaped frame formed at the peripheral edge of the first opening and the second opening, and inserted into the first opening or the second opening, wherein the door opening-closing coordination rod abuts the frame such that the door opening-closing coordination rod is capable of being slid by the second biasing member.
