Referring to the drawings, the air vent device 1 for a vehicle according to an embodiment of the present invention includes a housing 10, a wing guide 20, a vertical wing 30, a horizontal wing 40, and a wing knob 50. can do.

The housing 10 is connected to a duct (not shown) and has a passage 11 through which air flows. When air flows in through the duct, it flows along the passage 11 of the housing 10 and is discharged into the interior of the vehicle. It can be configured as follows.

The housing 10 can be mounted at a set position on the vehicle's dashboard (not shown) so that the exit side faces the interior.

In an embodiment, the housing 10 may be formed in a rectangular shape with a low overall height and long left and right lengths to implement a slim air vent.

A frame 60 may be fitted and mounted on the outlet side of the housing 10.

The frame 60 includes a pair of horizontal frame portions 61 disposed at the upper and lower portions of the passage 11, respectively, on the exit side of the housing 10, and a pair of vertical frames connected to the ends of the horizontal frame portion 61. It may include a frame portion 62. Accordingly, the frame 60 may be formed in a rectangular shape corresponding to the housing 10.

In an embodiment, the horizontal frame portion 61 may have an inclined surface 61a that is inclined diagonally inward from the outlet side of the housing 10. Accordingly, the passage 11 within the housing 10 may have a structure in which the gap toward the outlet narrows due to the inclined surface 61a.

The guide hole 21 guides the vertical movement of the horizontal wing 40, which will be described later, and may provide a trajectory that limits the range of movement.

As shown in FIG. 4, the guide hole 21 may be formed in a straight line. Accordingly, the horizontal wing 40 moves up and down along the straight trajectory of the guide hole 21.

Additionally, as shown in FIG. 5, the guide hole 21 may be formed in a curved shape that draws an arc toward the front. Accordingly, the horizontal wing 40 moves up and down along the curved trajectory of the guide hole 21.

A vertical wing 30 and a horizontal wing 40 may be installed within the housing 10 to control the wind direction of the air (A).

The vertical wing 30 is disposed inside the passage 11 of the housing 10 and can be installed to be rotatable in the left and right directions.

Referring to FIG. 6 along with FIG. 2, a plurality of vertical wings 30 are provided, and the hinge shaft 31 may be formed to protrude from the upper and lower surfaces, respectively.

The hinge axis 31 of each vertical wing 30 is arranged in a direction perpendicular to the flow direction of air (A) within the housing 10 and is a pair of fixtures fixed to the upper and lower surfaces of the passage 11, respectively. It can be rotatably mounted on the bar 33.

In addition, the vertical wing 30 may be provided with a connection pin 32 that protrudes upward from the rear end of the upper surface. In addition, the connection pin 32 of each vertical wing 30 may be rotatably connected to the drive bar 34 disposed in parallel with the fixed bar 33 at the top of the vertical wing 30. Accordingly, the plurality of vertical wings 30 rotate in the left and right directions based on the hinge axis 31, and all rotate in the same direction by the drive bar 34 connected to the connecting pin 32.

The vertical wing 30 disposed in the center among the plurality of vertical wings 30 may be provided with a connecting bar 35 extending in the vertical direction of the housing 10.

The horizontal wing 40 is disposed in front of the vertical wing 30 and can be installed to be rotatable in the up and down directions.

The rear end of the horizontal wing 40 may be rotatably mounted on the side wall 12 of the housing 10 for vertical rotation. And, the front end may be configured to be connected to the guide hole 21 of the wing guide 20.

Referring to Figures 7 and 8 along with Figure 2, the horizontal wing 40 may be provided with a hinge axis 41 that protrudes outward on both sides of the rear end and is fastened to the fastening hole 13 formed in the side wall 12. You can.

In addition, the horizontal wing 40 may be provided with guide pins 42 that protrude outward on both sides of the front end and are inserted and connected to the guide hole 21.

Accordingly, the rear end of the horizontal wing 40 rotates based on the hinge axis 41, and the front end moves up and down along the guide hole 21 through the guide pin 42.

In an embodiment, the fastening hole 13 to which the hinge axis 41 of the horizontal wing 40 is fastened may have a slot-shaped structure cut in a straight line of a predetermined length toward the front exit side. In this case, the guide hole 21 may have a straight structure.

4A to 4C schematically show a state in which the horizontal wing 40 is rotated up and down in the straight guide hole 21.

As shown in FIG. 4A, when the horizontal wing 40 is in a normal state, the hinge shaft 41 may be located in the rear area of the fastening hole 13.

And, as shown in Figures 4b and 4c, the guide pin 42 moves in the vertical direction along the straight trajectory of the guide hole 21 so that the horizontal wing 40 is rotated upward or downward. When this happens, the hinge axis 41 moves along the fastening hole 13 and is located in the front area.

As the hinge axis 41 moves along the fastening hole 13, the trajectory of the guide pin 42 along the straight guide hole 21 can be guaranteed.

In an embodiment, when the guide hole 21 has a curved structure, the fastening hole 13 may have a circular structure.

Figures 5a to 5c schematically show a state in which the horizontal wing 40 is rotated up and down in the curved guide hole 21.

As shown in FIGS. 5A to 5C, the guide pin 42 moves up and down along the curved trajectory of the guide hole 21, so that the horizontal wing 40 changes to the normal state, the upward rotation state, and the downward rotation state. Even so, the hinge axis 41 rotates while its position is fixed in the fastening hole 13.

Meanwhile, the horizontal wing 40 has an insertion hole 43, and the wing knob 50 can be inserted into the insertion hole 43 and fastened to the horizontal wing 40.

The insertion hole 43 may be formed by penetrating the horizontal wing 40 in the front and rear directions, and the horizontal wing 40 may have a structure in which the front and back sides are open at the insertion hole 43.

The wing knob 50 may include a knob portion 51 disposed on the front of the horizontal wing 40 and an extension portion 52 that extends from the rear end surface of the knob portion 51 and is inserted into the insertion hole 43. there is.

The rear end surface of the knob portion 51 in contact with the front surface of the horizontal wing 40 may be formed as a curved surface corresponding to the front shape of the horizontal wing 40. Accordingly, the extension portion 52 can be moved left and right along the longitudinal direction of the horizontal wing 40 while it is inserted into the insertion hole 43.

Additionally, the knob portion 51 may be formed to have an overall thickness corresponding to the thickness of the horizontal wing 40. Accordingly, the air (A) moving along the surface of the horizontal wing 40 can be discharged into the interior of the vehicle without any significant resistance, so that the wind direction in the desired direction can be adjusted more accurately and reliably. Air volume loss can also be minimized.

The extension portion 52 may extend from the rear end surface of the knob portion 51, cross the horizontal wing 40, and be disposed within the insertion hole 43.

As shown in FIGS. 8 and 9, the extension portion 52 may be provided with hooks 53 protruding on both left and right sides at the end portion. And, a connection knob 70 connected to the vertical wing 30 may be fastened to the end.
