Description

Technical Field

[0001] The present disclosure relates to a vent, and more particularly, to a vent capable of adjusting wind direction by providing a knob outside an air outlet. Background Art

[0002] The vent is located at the end of the airflow path formed in the vehicle air conditioning system and is a portion through which air is discharged. The vent discharges air into the vehicle and adjusts the air state inside the vehicle, and since the vent discharges air into the vehicle interior where passengers are located, a knob is applied to adjust the air discharge direction.

[0003] For the vents used in the prior art, a knob is provided on the air outlet, and the passenger can adjust the wind direction by moving the knob up and down or left and right. However, when the knob is provided on the air outlet, the knob may exert resistance on the discharged air and interfere with the direction of the discharged air.

[0004] In recent years, attempts have been made to realize slender vents for good design in vehicle interiors, but there is a limit to reducing the size of the knob, so vents in which the knob is removed from the air outlet are being studied. Utility Model Content

[0005] One embodiment of the present disclosure is to provide a vent which can realize up and down wind and left and right wind through a knob, and is used to adjust the wind direction by arranging the knob outside the air outlet of the vent.

[0006] Problems to be solved by the present disclosure are not limited to the above-mentioned problems, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

[0007] According to one aspect of the present disclosure, an air vent is provided, the vent comprising: an air outlet that opens at one side and discharges air; a first wing that is disposed at the open side of the air outlet and guides air upward or downward by rotating up and down; a second wing that is disposed at a rear side of the first wing and guides air leftward or rightward by rotating leftward and rightward; and a knob that can move forward and backward and interlocks with the first wing or the second wing depending on the setting of the knob.

[0008] The knob may be disposed outside the air outlet.

[0009] A rotating shaft may be formed to extend on a rear surface of the knob, a first gear and a second gear may be formed on the rotating shaft at predetermined intervals in a radial direction of the rotating shaft, and the first gear may be interlocked with the first wing and the second gear may be interlocked with the second wing, so that when the knob is rotated, the first wing or the second wing moves.

[0010] The vent may further include a protrusion protruding from a side surface of the first wing and having a bent end, and a first cam provided at a rear side of the knob in parallel with the air outlet and having a through hole formed so that an end of the protrusion passes therethrough.

[0011] The protrusion may be disposed at a predetermined interval from a rotation axis of the first wing so that when the first cam rotates, the protrusion moves up and down to allow the first wing to rotate.

[0012] The vent may include a link portion connected to one side of the second wing and having a bent end, and a second cam disposed at a rear side of the knob in parallel with the air outlet and having a through hole formed so that an end of the link portion passes therethrough.

[0013] When the second cam rotates, the link portion suspended from the second cam may move left and right to allow the second wing to rotate left and right.

[0014] Gear protrusions may be formed on opposing surfaces of the first cam and the second cam, and when the knob moves forward and backward, the first gear or the second gear may be interlocked with the gear protrusion formed on the first cam or the second cam.

[0015] A distance between the first cam and the second cam may be formed to be greater than a distance between the first gear and the second gear formed on the rotation shaft of the knob.

[0016] The first gear and the second gear may be disposed in a space between the first cam and the second cam.

[0017] When the knob is set forward, the first gear may engage and interlock with a gear protrusion formed on the first cam, and when the knob is set backward, the second gear may engage and interlock with a gear protrusion formed on the second cam.

[0018] In the case where the knob is interlocked with the first cam, when the knob is rotated, the first cam can rotate to rotate the protrusion up and down to allow the first wing to rotate up and down, and in the case where the knob is interlocked with the second cam, when the knob is rotated, the second cam can rotate to move the link part left and right to allow the second wing to rotate left and right.

[0019] The knob may be initially set in a position where at least one of the first gear or the second gear is interlocked with the first cam or the second cam, and an elastic body for providing elastic force to maintain the state in which the knob is set in the initial position of the knob may be set on the rotating axis of the knob.

[0020] Holes may be formed at the centers of the first and second cams so that the rotation shaft extending from the knob can move forward and backward through the first and second cams. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Hereinafter, one embodiment of a vent according to the present disclosure will be described in detail with reference to the accompanying drawings, and in the description given with reference to the accompanying drawings, the same or corresponding components will be given the same reference numerals and overlapping descriptions thereof will be omitted.

[0037] The vent for discharging air into the vehicle can adjust the wind direction by a knob 400. Generally, the knob 400 can be arranged inside the air outlet 100 of the vent so that the user can adjust the wind direction by pushing the knob 400 up and down or left and right.

[0038] When the knob 400 is disposed inside the air outlet 100, the knob 400 may interfere with the flow of the exhaust air, which may make it difficult to control the wind direction. In addition, in recent years, elongated vents have been designed, but when the knob 400 is located inside the air outlet 100, the size of the knob 400 limits the reduction of the vent.

[0039] The present disclosure provides a vent in which a knob 400 may be disposed outside an air outlet 100, allowing for easy adjustment of up and down and left and right wind directions.

[0040] Figure 1 is a perspective view of a vent according to an embodiment of the present disclosure.

[0041] Reference Figure 1 The vent according to one embodiment of the present disclosure may include a first wing 200 disposed inside the air outlet 100 and a second wing 300 disposed at a rear side of the first wing 200 .

[0042] The first wing 200 can adjust the wind direction up and down, and the second wing 300 can rotate left and right to adjust the wind direction. The arrangement of the first wing 200 and the second wing 300 can be changed, and the first wing 200 can also be arranged at the rear side of the second wing 300.

[0043] The knob 400 may be disposed on the side surfaces of the air outlet 100, the first wing 200, and the second wing 300. When the knob 400 interlocks with the first wing 200 or the second wing 300 according to the setting of rotating the knob 400, the first wing 200 or the second wing 300 may move, thereby adjusting the wind direction.

[0044] The knob 400 is disposed outside the air outlet 100, and in this embodiment, is shown as being disposed on the right side of the air outlet 100, but there is no limitation as long as the knob 400 can be disposed outside the air outlet 100 to easily adjust the wind direction.

[0045] The knob 400 may be configured to be movable forward and backward by a predetermined distance outside the air outlet 100. The user may adjust the position of the knob 400 by pulling or pushing the knob 400, the knob 400 may be interlocked with the first wing 200 or the second wing 300 depending on the configuration of the knob 400, and the wind direction may be adjusted by rotating the knob 400 to control the movement of the first wing 200 or the second wing 300.

[0046] Figure 2is a view showing a vent according to one embodiment of the present disclosure.

[0047] Reference Figure 2 , the knob 400 may be interlocked with the first wing 200 and the second wing 300 by a gear and a cam. The rotation shaft 410 may be formed in the knob 400 in an inner direction. Two gears, namely, a first gear 420 and a second gear 430 may be disposed in a radial direction along the rotation shaft 410. The first gear 420 and the second gear 430 may be disposed at a predetermined interval.

[0048] The cams 210 and 310 may be disposed outside the rotation shaft 410 of the knob 400. The cams may include a first cam 210 connected to the first wing 200 and a second cam 310 connected to the second wing 300. The first cam 210 and the second cam 310 may rotate to allow the first wing 200 and the second wing 300 to move.

[0049] The first cam 210 and the second cam 310 may be disposed in a direction parallel to the air outlet 100, which corresponds to a plane perpendicular to the rotation shaft 410 extending from the knob 400. The first cam 210 and the second cam 310 may be disposed at a predetermined interval, and may be disposed at an interval wider than the interval between the first gear 420 and the second gear 430. That is, the first gear 420 and the second gear 430 may be disposed in the space between the first cam 210 and the second cam 310. This is to ensure that the knob 400 moves forward and backward so that the first cam 210 or the second cam 310 is interlocked with the first gear 420 or the second gear 430.

[0050] The first gear 420 and the second gear 430 may be disposed between the first cam 210 and the second cam 310, and by moving the knob 400 forward and backward, the first gear 420 or the second gear 430 may move together and interlock with the first cam 210 or the second cam 310. That is, according to the setting of the knob 400, only one of the first cam 210 or the second cam 310 may be interlocked to adjust the angle of the first wing 200 or the second wing 300.

[0051] As described above, in the present embodiment, the first wing 200 may be disposed inside the air outlet 100, and the second wing 300 may be disposed at the rear side of the first wing 200. The rotation shaft 220 of the first wing 200 is formed in front of the first wing 200 parallel to the longitudinal direction of the air outlet 100, and a portion of the first wing 200 interlocked with the first cam 210 is disposed at the rear side of the rotation shaft 220, so that the first wing 200 can rotate up and down around the rotation shaft 220.

[0052] The second wing 300 may include a plurality of wings 300 arranged parallel to the height direction of the air outlet 100, and each wing 300 may be arranged in parallel at predetermined intervals. The rotation axis 320 of each wing 300 may be formed parallel to the height direction of the air outlet 100 and may rotate simultaneously.

[0053] Figure 3 is a view showing a knob and a cam of a vent according to one embodiment of the present disclosure.

[0054] Reference Figure 3 According to an embodiment of the present disclosure, the vent knob 400 and the cams 210 and 310 may be interlocked by a gear structure. The rotation shaft 410 is formed to extend at the rear side of the knob 400, and the first gear 420 and the second gear 430 may be formed on the rotation shaft 410 in a radial direction.

[0055] Gear protrusions 212 and 312 may be formed on the first cam 210 and the second cam 310, respectively, so that the first gear 420 and the second gear 430 are interlocked. In detail, holes 216 and 316 may be formed in the central portion of the rotating shaft 410 corresponding to the first cam 210 and the second cam 310 so that the rotating shaft 410 extending from the knob 400 passes therethrough. The first cam 210 and the second cam 310 may be disposed outside the first gear 420 and the second gear 430, and may be formed radially outside the rotating shaft 410. Gear protrusions 212 and 312 may be formed on opposing surfaces of the first cam 210 and the second cam 310. Gear protrusions 212 and 312 may be formed to interlock with the first gear 420 and the second gear 430.

[0056] When the user pulls the knob 400 forward, the first gear 420 may engage and interlock with the gear protrusion 212 formed on the first cam 210. When the user pushes the knob 400 backward, the second gear 430 may engage and interlock with the gear protrusion 312 formed on the second cam 310.

[0057] In the present embodiment, the knob 400 and the rotation shaft 410 are shown to be disposed at the center of the first cam 210 and the second cam 310, but the first cam 210 and the second cam 310 may be disposed on one side of the knob 400 and the rotation shaft 410, and may be interlocked with the first gear 420 and the second gear 430 formed on the knob 400. In detail, the first cam 210 and the second cam 310 may have a gear structure formed on the edge thereof, and may be engaged and interlocked with the first gear 420 and the second gear 430 disposed on the rotation shaft 410 of the knob 400. In this case, the knob 400, the first cam 210 and the second cam 310 rotate around separate rotation shafts.

[0058] Figure 4 is a view showing a first cam according to an embodiment of the present disclosure, Figure 5 is a view showing a second cam according to one embodiment of the present disclosure.

[0059] Reference Figure 4 and Figure 5 , the first cam 210 and the second cam 310 according to one embodiment of the present disclosure may have through holes 214 and 314 formed to interlock with the first wing 200 and the second wing 300 , and gear protrusions 212 and 312 may be formed on opposite surfaces of the first cam 210 and the second cam 310 .

[0060] Holes 216 and 316 may be formed at the center of the first cam 210 and the second cam 310 so that the rotation shaft 410 connected to the knob 400 passes therethrough. The rotation shaft 410 may be disposed to pass through the holes 216 and 316 formed at the center of the first cam 210 and the second cam 310, and when the knob 400 is rotated, the rotation shaft 410 may rotate within the holes 216 and 316 formed at the center of the cam that is not interlocked with the knob 400. The cam interlocked with the knob 400 may rotate together with the rotation shaft 410.

[0061] The gear protrusion 212 may be formed on the first cam 210 to interlock with the first gear 420. The gear protrusion 212 may be formed on a surface of the first cam 210 facing the second cam 310, and the surface corresponds to a rear surface of the first cam 210 based on the front of the vehicle air conditioning system. The gear protrusion 212 may be formed to protrude from one side of the first cam 210, and may be formed to correspond to a gear structure of the first gear 420.

[0062] In detail, since the first gear 420 is formed in a radial direction from the rotation shaft 410 connected to the knob 400, the gear protrusion 212 formed on the first cam 210 may be formed to have a hollow center by including a hole 216 in which the rotation shaft 410 is disposed, and to extend in a radial direction based on the rotation shaft 410. The gear protrusion 212 may be formed to correspond to a gear groove of the first gear 420, and may be interlocked with the first gear 420 by being inserted into the gear groove.

[0063] The gear protrusion 312 may be formed on the second cam 310 to interlock with the second gear 430. The gear protrusion 312 may be formed on a surface of the second cam 310 facing the first cam 210, and the surface corresponds to the front surface of the second cam 310 based on the front of the vehicle air conditioning system. The gear protrusion 312 may be formed to protrude from one surface of the second cam 310, and may be formed to correspond to the gear structure of the second gear 430.

[0064] In detail, since the second gear 430 is formed in a radial direction from the rotation shaft 410 connected to the knob 400, the gear protrusion 312 formed on the second cam 310 may be formed to have a hollow center by including a hole 316 in which the rotation shaft 410 is disposed, and to extend in a radial direction based on the rotation shaft 410. The gear protrusion 312 may be formed to correspond to a gear groove of the second gear 430, and may be interlocked with the second gear 430 by being inserted into the gear groove.

[0065] The first gear 420 and the second gear 430 may also be formed to the same specifications, and therefore, the gear protrusion 212 of the first cam 210 and the gear protrusion 312 of the second cam 310 may also be formed to the same specifications.

[0066] A through hole 214 for interlocking with the first wing 200 may be formed in the first cam 210. For a protrusion 230 protruding from one side of the first wing 200 and having a bent end, the end may be suspended in the through hole 214 of the first cam 210, thereby interlocking the first wing 200 and the first cam 210. When the first cam 210 is interlocked with the knob 400 and rotated in a state where the protrusion 230 is suspended in the through hole 214 of the first cam 210, the protrusion 230 may be rotated together to allow the first wing 200 to rotate up and down.

[0067] A through hole 314 for interlocking with the second wing 300 may be formed in the second cam 310. A link portion 330 may be connected to one side of the second wing 300. The link portion 330 may have a bent end, and the bent end may be suspended in the through hole 314 formed in the second cam 310 so that the second cam 310 and the second wing 300 are interlocked. When the second cam 310 is interlocked with the knob 400 and rotated in a state where the link portion 330 is suspended on the second cam 310, the link portion 330 may move left and right.

[0068] The through hole 214 of the first cam 210 may have an elongated hole shape extending radially around the rotation shaft 410 to rotate the protrusion 230 of the first wing 200 up and down. The through hole 314 of the second cam 310 may have an elongated hole shape that is wider in a direction perpendicular to a radial direction centered on the rotation shaft 410 to move the link portion 330 of the second wing 300 in a horizontal direction.

[0069] The method of interlocking the first cam 210 and the second cam 310 with the first wing 200 and the second wing 300 can be realized by a slot and pin structure. In detail, the slot can be formed on one surface of each of the first cam 210 and the second cam 310, and the pin can be formed to protrude from the ends of the first wing 200 and the second wing 300. When the first cam 210 and the second cam 310 rotate, the pin can be placed in the slot and move by sliding in the slot. The shape of the slot can be formed to correspond to the direction in which the pin moves, and can be formed so that the rotational motion of the cams 210 and 310 can be converted into the linear motion of the pin.

[0070] The rotation angles of the first wing 200 and the second wing 300 may have limits. When the air discharged from the air outlet 100 discharges the maximum upward wind, the first wing 200 may rotate upward at the maximum angle, and when the air discharges the maximum left wind, the second wing 300 may rotate as far to the left as possible.

[0071] When there is a limit to the rotation angle of the first wing 200 and the second wing 300, the rotation angle of the first cam 210 and the second cam 310 interlocked therewith may have a limit corresponding to the rotation angle of the first wing 200 and the second wing 300. Therefore, a stopper may be provided at one side of each of the first cam 210 and the second cam 310 to fix the first cam 210 and the second cam 310 so that the first cam 210 and the second cam 310 rotate only to the maximum rotation angle.

[0072] In this case, when the first cam 210 and the second cam 310 discharge air in a desired direction by the rotation of the knob 400, the first cam 210 and the second cam 310 may be fixed to maintain the corresponding settings. That is, the movements of the first cam 210 and the second cam 310 may be fixed in their respective settings. When the first cam 210 or the second cam 310 is not interlocked with the knob 400, there may be a certain degree of resistance on the rotation shaft 410 of the first cam 210 or the second cam 310 to prevent the rotation shaft 410 from rotating.

[0073] Figure 6 is a view showing a state in which a second cam and a knob are interlocked according to an embodiment of the present disclosure, Figure 7 is a view showing a state in which a first cam and a knob are interlocked according to one embodiment of the present disclosure.

[0074] Reference Figure 7 When the knob 400 is pulled forward, the first gear 420 formed on the rotating shaft 410 engages with the gear protrusion 212 formed on the first cam 210, thereby interlocking the knob 400 and the first cam 210. Then, when the knob 400 is rotated clockwise or counterclockwise, the first wing 200 interlocked with the first cam 210 can rotate up and down.

[0075] Reference Figure 6 When the knob 400 is pushed backward, the second gear 430 formed on the rotating shaft 410 engages with the gear protrusion 212 formed on the second cam 310, thereby interlocking the knob 400 and the second cam 310. Then, when the knob 400 is rotated clockwise or counterclockwise, the second wing 300 interlocked with the second cam 310 can rotate left and right.

[0076] The initial setting of the knob 400 may be a setting in which the first gear 420 and the second gear 430 are positioned between the first cam 210 and the second cam 310 so that neither the first gear 420 nor the second gear 430 engages with the first cam 210 and the second cam 310. In this case, an elastic body may be provided at the end of the rotating shaft 410 to apply an elastic force so that the knob 400 can be fixed in the above position.

[0077] As an example, the elastic body may be a spring. The spring may be provided at the end of the rotating shaft 410 to provide an elastic force in the axial direction. When the user pulls the knob 400, the spring may stretch and provide an elastic force in the direction of pushing the knob 400 forward, and when the user pushes the knob 400, the spring may be compressed and provide an elastic force in the direction of pulling the knob 400 backward. That is, when the user removes the force applied by pulling or pushing the knob 400, the first gear 420 and the second gear 430 may be positioned in the space between the first cam 210 and the second cam 310.

[0078] Alternatively, the initial setting of the knob 400 may be a setting in which the first gear 420 or the second gear 430 is engaged with the first cam 210 or the second cam 310. In this case, when the user does not apply any force to the knob 400, the knob 400 may maintain a state in which the first cam 210 is engaged with the first gear 420 or the second cam 310 is engaged with the second gear 430. The user may adjust the initially disengaged cams and gears to engage by pulling or pushing the knob 400 in a direction opposite to the elastic force.

[0079] Figure 8 is a view illustrating movement of a first wing according to one embodiment of the present disclosure.

[0080] Reference Figure 8When the knob 400 is pulled forward, the first gear 420 may engage and interlock with the first cam 210, and when the user rotates the knob 400, the first cam 210 may rotate, and the first wing 200 suspended in the through hole 214 of the first cam 210 may rotate together. The rotation shaft 220 of the first wing 200 may be provided in front of the first wing 200, and when the protrusion 230 formed to protrude and bend from the rear of the first wing 200 rotates, the first wing 200 is allowed to rotate up and down based on the rotation shaft 220.

[0081] exist Figure 8 In this case, when the knob 400 is rotated clockwise based on the front of the vent, the protrusion 230 of the first wing 200 may rotate upward, so that the first wing 200 is arranged to face downward to discharge downward wind. When the knob 400 is rotated counterclockwise based on the front of the vent, the protrusion 230 of the first wing 200 may rotate downward, so that the first wing 200 is arranged to face upward to discharge upward wind.

[0082] In order to rotate the protrusion 230 of the first wing 200 up and down, the through hole 214 of the first cam 210 must move up and down when the first cam 210 rotates. In order to achieve the up and down movement, the through hole 214 can be set on the left or right side of the first cam 210. That is, when the knob 400 is rotated clockwise or counterclockwise by a predetermined angle in a state where the protrusion 230 of the first wing 200 is suspended on the left or right side of the first cam 210, the protrusion 230 can be rotated to the lower side or upper side of the first cam 210 to achieve upward and downward wind. Figure 1 In the case of FIG. 2 , the through hole 214 of the first cam 210 is shown to be disposed on the left side.

[0083] Fig. 9 is a view illustrating movement of a second wing according to one embodiment of the present disclosure.

[0084] Reference Fig. 9 , when the knob 400 is pushed backward, the second gear 430 may engage and interlock with the second cam 310, and when the user rotates the knob 400, the second cam 310 may rotate, and the second wing 300 suspended on the through hole 314 of the second cam 310 may rotate together. The rotation shaft 320 of the second wing 300 may be formed to extend up and down based on the front of the vent, and may rotate left and right. On one side of the second wing 300, the link part 330 may interlock the second wing 300 and the second cam 310, and when the second cam 310 rotates, the link part 330 may move left and right to allow the second wing 300 to rotate.

[0085] exist Fig. 9In the case of the present invention, when the knob 400 is rotated clockwise based on the front of the vent, the link part 330 may move leftward so that the second wing 300 is arranged to face right to discharge rightward wind. When the knob 400 is rotated counterclockwise based on the front of the vent, the link part 330 may move rightward so that the second wing 300 is arranged to face left to discharge leftward wind.

[0086] In order to make the link part 330 provided on one side of the second wing 300 move left and right, the through hole 314 of the second cam 310 must move left and right according to the rotation of the second cam 310. In order to achieve left and right movement, the through hole 314 can be provided on the upper side or right side of the second cam 310. That is, when the knob 400 is rotated clockwise by a predetermined angle in a state where the link part 330 of the second wing 300 is located on the upper side of the second cam 310, the link part 330 can be moved to the right or left side of the first cam 210 to allow the second wing 300 to rotate, thereby achieving left and right wind. Figure 1 In the case of FIG. 5 , the through hole 314 of the second cam 310 is shown to be disposed on the upper side.

[0087] According to one embodiment of the present disclosure, the wind direction can be adjusted up and down or left and right according to the front and back setting of the knob disposed outside the air outlet, so that no resistance is applied to the discharged air.

[0088] Various beneficial advantages and effects of the present disclosure are not limited to the above contents and should be easily understood through the description of the detailed embodiments of the present disclosure.

[0089] Although specific embodiments of the present disclosure have been described above, it should be understood that a person skilled in the art could make various changes and modifications to the present disclosure without departing from the spirit and scope of the present disclosure.
