Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

2 to 4, an air vent structure of an automobile according to the present invention includes a dashboard 10, an instrument panel 20, a gap formed between the dashboard 10 and the instrument panel 20 An air conditioning unit 40 installed inside the dashboard 10 and a duct 50 connecting the air conditioning unit 40 and the gap 30.

The dashboard 10 refers to the entire lower portion of the windshield glass, which is the front portion of the driver's seat, the center console, and the front passenger's seat. Various instrument panels, manual controls, glove boxes and other accessories. The dashboard 10 is provided with the air conditioning unit 40 in an inner central empty space.

The instrument panel 20 refers to the portion of the dashboard 10 where the instrument panel and manual controls are installed.

The instrument panel 20 to which the present invention is applied is a panel that traverses the entire lateral direction of the dashboard 10 from the left end to the right end of the dashboard 10, , A speedometer (vehicle speed), a coolant thermometer, a fuel meter, and various warning lamps, and is manufactured as an article separate from the dashboard 10.

Also, the instrument panel 20 may be provided with a touch screen type display panel for displaying a navigation screen and displaying a screen implementing an interface for audio and air conditioning control.

The instrument panel 20 is installed in a state where the front cavity of the dashboard 10 is shielded and the gap 30 is formed between the instrument panel 20 and the dashboard 10 over the entire circumference of the instrument panel 20. [ Is formed. That is, the gap 30 is formed on the upper, lower, left, and right sides of the instrument panel 20, all of which are connected to each other.

 The instrument panel 20 is fixed to the dashboard 10 by a mounting bracket and fastening parts. In addition, the instrument panel 20 may be mounted on the dashboard 10 via hinge shafts at both ends thereof to adjust the front inclination angle or to completely rotate the instrument panel 20 so that other instruments mounted on the rear surface are exposed to the front side.

The air conditioning unit 40 is installed deep inside the dashboard 10 and at an intermediate portion (corresponding to the front portion between the driver's seat and the front passenger's seat) as viewed from the front.

In the air conditioning unit 40, an evaporator for cooling, a heater core for heating and a heater core for heating, and a fan for blowing air are installed.

The duct 40 is installed in the space between the air conditioning unit 40 and the instrument panel 20 inside the dashboard 10.

The duct 40 has a housing shape in which a rear surface is closed and an inner cavity is opened to the front and has a transverse length corresponding to the entire area in the transverse direction of the dashboard 10, And an inlet 51 connected to the air outlet is formed.

The front portion of the duct 40 is blocked by the instrument panel 20 and the internal space of the duct 40 (i.e., the cavity portion) is separated from the gap (not shown) formed between the dashboard 10 and the instrument panel 20 30).

Therefore, when the driver or the passenger of the passenger seat operates the air conditioner and the heater operating means (the interface screen implemented in the mechanical lever, the button or the display panel) provided in the instrument panel 20, Is blown through the duct (50) to the interior of the vehicle through the gap (30) between the dashboard (10) and the instrument panel (20).

Since the gap 30 is formed over the entire circumference of the instrument panel 20, the cold air or the hot air is discharged from the entire front surface area of the dashboard 10, rather than being discharged from a vent hole provided at a specific position .

Therefore, when the air conditioner or the heater is turned on, the cold air or the warm air spreads more quickly throughout the indoor space, so that the passengers can feel the cooling and heating atmosphere more quickly.

Further, since cold air or warm air is discharged through a large area, the air discharge intensity is reduced as compared with a conventional vent hole, so that burdens and discomfort when the passengers directly hit the wind are reduced.

Since the cold air or the hot air is discharged through the gap 30 formed around the instrument panel 20 as described above, it is not necessary to provide separate vent holes in the instrument panel 20 at the left and right and center.

Therefore, since the portion where the vent hole is formed in the instrument panel 20 becomes empty, a new futuristic instrument panel design including the empty portion can be realized.

Meanwhile, as shown in FIG. 4, a guide member 60 having an arc-shaped cross section may be installed in the cavity of the duct 50.

The guide member 60 is installed in a state in which the convex rear surface faces toward the inlet port 51 and the concave front surface faces toward the instrument panel 20. But is mounted on the inner surface of the duct 50 by fastening means such as mounting brackets and bolts of appropriate shape.

The cold air and hot air blown from the air conditioning unit 40 through the inlet port 51 by the guide member 60 are guided by the dashboard 10 and the instrument panel (not shown) through the passage between the duct 50 and the guide member 60 20). ≪ / RTI >

Therefore, the cold air or warm air entering the inlet port 51 is mixed with the air flowing backward while colliding against the rear surface of the instrument panel 20, and moves to the path between the duct 50 and the guide member 60 without generating turbulence, (30), so that indoor discharge of cold air and warm air can be performed more smoothly.

FIG. 5 is an embodiment that can be implemented in addition to the present invention, in which an LED lamp 70 is installed near the gap 30 of the dashboard 10.

The LED lamp 70 is installed in a strip shape along the periphery of the gap 30. The LED lamp 70 is installed on the surface of the dashboard 10 or the duct 50 so as not to protrude from the instrument panel 20 toward the room. Therefore, the LED lamp 70 is not directly visible from outside, and only the light emitted from the LED lamp 70 is seen as an indirect light.

 The LED lamp 70 is an RGB LED that can realize various colors by current control including all three light sources of red, green, and blue, and receives a working current from a power source through a current control circuit 80.

The current control circuit 80 is connected to the control unit 90 and the air conditioner and the heater operation signal 100 are transmitted to the control unit 90. The control unit 90 controls the current control circuit 80 so that the LED lamp 70 emits blue when the input signal is the air conditioner operation signal when the air conditioner or the heater operation signal is inputted and when the input signal is the heater operation signal And controls the current control circuit 80 so that the LED lamp 70 emits red light.

When the air conditioner is operated and the cold air is discharged into the gap 30, a blue light band is formed along the gap 70. When the heater is operated and hot air is discharged, A band of light is formed.

Accordingly, the user can see whether the air conditioning function (cooling or heating) is operating as expected by looking at the light emission color of the LED lamp 70. If the user mistakenly operates the air conditioning function, he / have.

In addition, the light of the LED lamp 70, which is emitted in a strip shape, acts as another design element of the dashboard 10 and the instrument panel 20, so that a new interior aesthetic can be felt.

The LED lamp 70 may be installed around the instrument panel 20 instead of the dashboard 10 or the duct 50. In this case, the LED lamp 70 may be connected to the air conditioner 80 and the control unit 90, It can be installed inside the instrument panel 20 together with the heater operating part, so that the structure of the apparatus becomes more compact and the installation is easy.
