BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air vent, and more particularly, to a vehicle air vent capable of minimizing an energy loss of air while minimizing an installation size of the air vent.

An air conditioner is provided in the vehicle for generating warm or cool air for cooling and heating to supply the air to the room or to keep the interior of the vehicle in a pleasant condition at all times regardless of the external environment.

Such an air conditioner is also used for safe driving by eliminating the windshield glass and the frost generated in the windshield when the outside temperature is low, such as during the rainy season or the winter season.

Typically, the air conditioner comprises an inside / outside unit for sucking outside air or inside air and supplying the inside / outside unit to the air conditioning case, and an air conditioner case in which an evaporator and a heater core are sequentially installed inside to heat or cool the air, .

The air cooled or heated by the air conditioner is supplied to the inside of the vehicle via the vehicle air vent communicated with the air conditioner case, so that the inside of the vehicle is cooled and heated.

The structure of a typical vehicle air vent includes a duct housing of a certain type in which the air cooled or heated flows therein and a duct housing arranged laterally and longitudinally in front of the duct housing to adjust the direction of air discharged through the duct housing And a plurality of horizontal and vertical baffle members.

However, since each of the horizontal baffle and the vertical baffle are formed so as to intersect with each other, the overall size of the horizontal baffle and the vertical baffle are increased, and a wide installation space is required.

In addition, since the size and the length in the front-rear direction are increased, the energy of the air supplied from the air conditioner is lost, thereby deteriorating the air conditioning efficiency.

In this embodiment, the shape is shown as a shape having a substantially trapezoidal longitudinal section having a long side and a short side, but it is not limited to any shape capable of controlling the air flow in the duct housing 12 in various directions.

The horizontal baffle 120 is rotated by receiving the rotational force of the intermediate gear 111 so that the direction of air flow can be controlled up and down.

Hereinafter, the downstream side along the air discharge direction of the horizontal baffle 120 is defined as the direction in which the air is discharged in the duct housing 12, and the opposite direction is defined as the upstream side.

An auxiliary baffle 122 may be formed on the upstream side of the horizontal baffle 120 to rotate in a direction opposite to the rotation direction of the horizontal baffle 120.

Further, a plurality of vertical baffles 113 may be provided so that one link member (not shown) connects one end of each vertical baffle 113 so that the vertical baffles 113 can be rotated in the same direction.

The third drive gear 133 is integrally rotated with the first drive gear 131 and the second drive gear 132 as described above and is engaged with the damper drive gear 151 of the eccentric member 150 Can be rotated.

The damper drive gear 151 is engaged with the third drive gear 133 and may include an eccentric member 150, a first slit 152, a second slit 153, and a damper guide member 160 have.

The damper drive gear 151 is integrally rotated with the eccentric member 150 so that the damper drive gear 151 is engaged with the third drive gear 133 and rotated so that the eccentric member 150 can be rotated .

The eccentric member 150 may include a first slit 152 and a second slit 153, which are penetrated in the thickness direction and formed in respective arc shapes.

5 and 6, the eccentric member 150 is formed in a flat plate shape parallel to the side surface of the duct housing 12, and includes a first slit 152 curved at a predetermined curvature, And a second slit 153 extending from one end of the first slit 152 and bent at a predetermined angle.

Particularly, since the eccentric member 150 is rotated about the rotation axis of the damper driving gear 151 and the damper driving gear 151 is formed at one end of the eccentric member 150, the eccentric member 150 is eccentrically rotated .

The first slit 152 and the second slit 153 formed in the thickness direction of the eccentric member 150 are curved with a predetermined curvature and the first slit 152 and the second slit 153 are provided with damper guide members 152, The guide protrusions 161 of the guide protrusion 160 can be inserted and relatively moved.

The guide protrusion 161 protrudes from the damper guide member 160 toward the eccentric member 150 and is inserted into the first slit 152 and the second slit 153 so that the guide protrusion 161 161 are slid along the first slit 152 and the second slit 153.

In addition, the damper member 162, which rotates integrally with the rotation of the damper guide member 160, opens and closes the inside of the duct housing 12.

The damper member 162 is hinged to the width direction of the duct housing 12 and is rotated by receiving the rotational force of the damper guide member 160 to open the duct housing 12 Or may be closed to prevent air flow from occurring.

Specifically, in a state in which the guide protrusion 161 is slid along the first slit 152, the damper member 162 is maintained in an open state, and the guide protrusion 161 slides along the second slit 153 The damper member 162 can be gradually rotated in the direction of closing the inside of the duct housing 12. [

The operation of the vehicle air vent according to an embodiment of the present invention as described above will be described below.

7 to 10 illustrate an operating state in which a lever member of an air vent slides according to an embodiment of the present invention.

7 (a), 7 (b), and 7 (c) are defined as initial positions, the guide projections 161 of the damper guide member 160 are engaged with the projections 161 of the eccentric member 150 Since the damper member 162 is positioned at the left end of the slit 152 so that the damper member 162 does not interfere with the air flow inside the duct housing 12.

In other words, the flat surface of the damper member 162 maintains a state parallel to the air flow direction so as not to interfere with the air flow flowing inside the duct housing 12.

As shown in FIG. 8A, when the lever member 101 moves to the right in the state of FIG. 7 and slides, the first extension rod 130 connected to the lever housing 102 moves to the right in the drawing.

8 (b), the first driving gear 131, which rotates while being rotated with the gear teeth of the first extension rod 130, is rotated in the counterclockwise direction, and the rotational force of the first driving gear 131 Is transmitted to the second extension rod (140) via the second drive gear (132).

As a result, the second extension rod 140 is moved to the left in the drawing, and at the same time, the plurality of vertical baffles 113 rotated in conjunction with the hinge bracket 141 hinged to the second extension rod 140 are rotated As shown in FIG. 8 (b), the airflow direction inside the duct housing 12 is controlled to be deflected to the left in the drawing and controlled so as to be controlled to be inclined from the right upper end to the left upper end.

8C, when the eccentric member 150 is rotated counterclockwise by the rotation of the damper driving gear 151, the guide protrusion 161 slides along the first slit 152 The damper member 162 is maintained in a non-rotating state.

7, when the lever member 101 moves to the left in the state of FIG. 7 and slides, the first extension rod 130 connected to the lever housing 102 through the contact portion 130a, Moves to the left in the drawing.

At this time, the first driving gear 131, which rotates in conjunction with the gear teeth of the first extension rod 130, is rotated clockwise, and the rotational force of the first driving gear 131 is transmitted through the second driving gear 132 And is transmitted to the second extension rod 140.

As a result, the second extension rod 140 is moved to the right in the drawing, and at the same time, the plurality of vertical baffles 113 rotating in conjunction with the second extension rod 140 are rotated. Therefore, So that the airflow direction inside the duct housing 12 is controlled to be deflected to the right side in the drawing and controlled to be discharged.

9C, when the eccentric member 150 is rotated in the counterclockwise direction by the rotation of the damper driving gear 151, the guide protrusion 161 moves along the first slit 152 Even if the slider 152 slides to the right end of the slit 152, the damper member 162 does not rotate as in the case of the damper member 162 of FIG.

9, when the lever member 101 is further moved to the left from the state of FIG. 9 and then slid, the first extension rod 130 connected to the lever housing 102 through the contact portion 130a, Moves to the left in the drawing. At this time, the moving distance of the lever member 101 to the left may be limited to the distance to the leftmost end of the first shaft 102a and the second shaft 102b.

At this time, the first driving gear 131, which rotates in conjunction with the gear teeth of the first extension rod 130, is rotated clockwise, and the rotational force of the first driving gear 131 is transmitted through the second driving gear 132 And is transmitted to the second extension rod 140.

The second extension rod 140 is moved to the right in the figure and the hinge bracket 141 rotated in conjunction with the second extension rod 140 maintains the current state such that the vertical baffle 113 is no longer rotated .

Specifically, the hinge bracket 141 is rotated around a rotation shaft 142 rotatably supported by the duct housing 12, and the second extension rod 140 is slidably inserted into the guide hole 141a, Respectively.

The guide hole 141a is formed in such a manner that the hinge bracket 141 rotates about the rotation axis 142 and rotates one of the plurality of vertical baffles 113 in one direction, So that the vertical baffle is no longer rotated.

In other words, the guide hole 141a is formed to penetrate through the thickness direction of the hinge bracket 141, and may be formed into an arc shape bent at a predetermined angle. While the hinge-engaged portion of the second extension rod 140 slides through the bent portion of the guide hole 141a (while advancing from the state of FIG. 9 to the state of FIG. 10), the rotation of the vertical baffle is stopped As shown in FIG.

10 (c), the vertical baffle 113 is not rotated. However, when the guide protrusions 161 are not engaged with the second slits 152 of the eccentric member 150, The damper member 162 is driven to rotate in the clockwise direction to close the air flow inside the duct housing 12. [

That is, when the air supplied to the user is not required, it can be achieved by sliding the lever member 101 to the leftmost end as described above.

Accordingly, since the horizontal baffle 120, the vertical baffle 113, and the damper member 162 are located inside the duct housing 12, the overall size of the duct is reduced to minimize the energy loss of the air .

In addition, since each component located inside the duct housing 12 can be controlled only by the operation of the lever member 101, a slim structure can be apparently formed.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
