[0002] This application claims priority to Korean Patent Application No. 10-2024-0164944, filed with the Korean Intellectual Property Office on November 19, 2024, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] This utility model relates to an air ventilation device for vehicles. Background Technology

[0004] Vehicles are typically equipped with an air conditioning system to control the interior temperature according to the season, and the cool or hot air produced by the air conditioning system is supplied to the vehicle interior through air vents installed on the dashboard. These air vents are equipped with air ventilation devices to control the direction and volume of the cool or hot air produced by the air conditioning system.

[0005] Conventional air ventilation systems employ airfoil-shaped air vents to control airflow direction vertically. However, exposed airfoils and knobs can reduce design flexibility, leading to airflow loss and interference with vertical airflow, thus degrading overall air conditioning performance. Therefore, improvements are needed. Utility Model Content

[0037] Figures 1 to 8 An air ventilation device for a vehicle and its configuration according to an embodiment of the present invention are shown.

[0038] Referring to the accompanying drawings, an air ventilation device 1 for a vehicle according to an embodiment of the present invention may include an air duct 100, a first air guide 200, a second air guide 300, a rotating member 400, and a wing module 500. In an embodiment, the air ventilation device 1 for a vehicle may further include a guide duct 600 connected to the air duct 100.

[0039] Air duct 100 can be connected to the vehicle's air conditioning system (not shown), so that cold and hot air generated from the air conditioning system can be supplied to the vehicle interior through air duct 100.

[0040] The air duct 100 may have an internal flow path P0 (along which air moves), a first flow path P1 branching upward from the internal flow path P0, and a second flow path P2 branching downward from the internal flow path P0. The air moving along the internal flow path P0 may move to at least one of the first flow path P1 and the second flow path P2.

[0041] The air duct 100 may include a duct housing 100A and a duct frame 100B installed in the duct housing 100A.

[0042] The pipe housing 100A may be composed of a separate but connected first body 110 and a second body 120. The internal flow path P0 may be located on one side of the pipe housing 100A, and the first flow path P1 and the second flow path P2 may be located on the other side.

[0043] The pipe housing 100A may have a pair of guide holes 111 and 121 on one of its two side surfaces, which extend along the internal flow path P0 in the front-rear direction. The guide holes 111 and 121 may have a straight slit-like structure. In an embodiment, the guide holes 111 and 121 may be respectively disposed in the first body 110 and the second body 120, and when the first body 110 and the second body 120 are connected, the guide holes 111 and 121 may be arranged parallel to each other.

[0044] The side cover 130 can be connected to one of the two side surfaces of the pipe housing 100A.

[0045] The side cover 130 is formed to cover the guide holes 111, 121 on the two side surfaces of the pipe housing 100A and the rotating member 400, and to prevent air in the internal flow path P0 from leaking out through the guide holes 111, 121. In this case, the rotation shaft 410 of the rotating member 400 can be configured to pass through the side cover 130 and extend to the outside.

[0046] The pipe frame 100B can be disposed in front of the internal flow path P0 to form a first flow path P1 and a second flow path P2 between the pipe frame 100B and the pipe shell 100A.

[0047] As shown in the figure, the pipe frame 100B may include: an upper inclined surface 141 extending upward from the center of the internal flow path P0; an upper plane 142 extending horizontally from the end of the upper inclined surface 141; a lower inclined surface 143 extending downward from the center of the internal flow path P0; and a lower plane 144 extending horizontally from the end of the lower inclined surface 143.

[0048] The upper inclined surface 141 and the upper plane 142 can form a first flow path P1 together with the inner surface of the first body 110. In addition, the lower inclined surface 143 and the lower plane 144 can form a second flow path P2 together with the inner surface of the second body 120.

[0049] The wing actuator 700 for driving the wing module 500 can be installed in the internal space S of the pipe frame 100B, that is, in the internal space S surrounded by the upper inclined surface 141, the upper plane 142, the lower inclined surface 143 and the lower plane 144.

[0050] Additionally, a connection hole 150a, surrounded by a fixing frame 150, may be provided on each of the upper plane 142 and the lower plane 144. The fixing frame 150 may include a pair of vertical columns 151 extending from the upper plane 142 and the lower plane 144, and a horizontal column 152 connecting the ends of the pair of vertical columns 151. The fixing frame 150 may be arranged along the width direction of the duct frame 100B perpendicular to the airflow direction. The wing module 500 may be fixedly inserted into the connection hole 150a.

[0051] The first air guide 200 and the second air guide 300 are configured to slide along the internal flow path P0 in the front-back direction and control the amount or volume of air passing through each of the first flow path P1 and the second flow path P2.

[0052] The first air guide 200 and the second air guide 300 can be respectively disposed at the upper and lower parts of the internal flow path P0 along the width direction of the pipe housing 100A, and can be connected to guide holes 111 and 121 to move linearly along guide holes 111 and 121. For example, the first air guide 200 can be connected to guide hole 111 in the first body 110, and the second air guide 300 can be connected to guide hole 121 in the second body 120. In this case, a gap G for air movement can be provided between the first air guide 200 and the first body 110, and between the second air guide 300 and the second body 120.

[0053] The first air guide 200 and the second air guide 300 may have a flat plate structure extending from one side surface of the pipe housing 100A to the other side surface.

[0054] In an embodiment, the lengths of the first air guide 200 and the second air guide 300 may correspond to the distance between the two side surfaces of the pipe housing 100A.

[0055] Furthermore, while moving forward along guide holes 111 and 121, the widths of the first air guide 200 and the second air guide 300 can cover the first flow path P1 and the second flow path P2, such that the front surfaces 201 and 301 contact the upper inclined surface 141 and the lower inclined surface 143 of the pipe frame 100B, respectively. In this case, the front surface 201 of the first air guide 200 can be configured as an upwardly inclined surface corresponding to the upper inclined surface 141 and formed to be in close contact with the upper inclined surface 141, and the front surface 301 of the second air guide 300 can be configured as a downwardly inclined surface corresponding to the lower inclined surface 143 and formed to be in close contact with the lower inclined surface 143.

[0056] The amount of air passing through the first flow path P1 and the second flow path P2 can be controlled by the degree to which the first air guide 200 and the second air guide 300 cover the first flow path P1 and the second flow path P2, respectively. That is, when the first flow path P1 and the second flow path P2 are set to completely cover each other, a portion of the air moves through the gap G and through the first flow path P1 and the second flow path P2, thereby reducing the amount of air. Conversely, when the first flow path P1 and the second flow path P2 are set to be fully open, the amount of air passing through the first flow path P1 and the second flow path P2 is increased to the maximum extent.

[0057] Specifically, the first air guide 200 and the second air guide 300 can slide in the front-to-back direction along the direction of air movement, thereby minimizing air resistance. Therefore, the impact on the airflow within the internal flow path P0 can be minimized, and thus no difference in the amount of air distributed to each of the first flow path P1 and the second flow path P2 occurs. Furthermore, there is no air loss due to the movement of the first air guide 200 and the second air guide 300 obstructing air movement and thus causing irregular flow (such as eddies) that prevents air from fully flowing into the first flow path P1 and the second flow path P2.

[0058] The first air guide 200 and the second air guide 300 may have guide protrusions 210 and 310, respectively, which are provided at two ends facing the side surface of the pipe housing 100A. The guide protrusions 210 and 310 are connected to guide holes 111 and 121. With the guide protrusions 210 and 310 connected to the guide holes 111 and 121, the first air guide 200 and the second air guide 300 slide along the guide holes 111 and 121.

[0059] The guide protrusion 210 of the first air guide 200 and the guide protrusion 310 of the second air guide 300 may be provided with connecting pins 220 and 320, respectively. The connecting pins 220 and 320 may be configured to protrude outward from the two side surfaces of the pipe housing 100A at the center of the guide protrusions 210 and 310.

[0060] The rotating member 400 is configured to move the first air guide 200 and the second air guide 300 in different directions by rotational drive.

[0061] The rotating member 400 can be rotatably mounted on both side surfaces of the pipe housing 100A and connected by a drive pin 440 to be driven to rotate in the same direction. In this case, the rotating member 400 can be disposed on the outer side surface of the pipe housing 100A, and the drive pin 440 can be disposed in the pipe housing 100A, traversing the internal flow path P0. The rotating member 400 can be connected to the actuator 710 and rotate clockwise or counterclockwise by the operation of the actuator 710.

[0062] The rotating member 400 may have a pair of connecting grooves 420 and 430 extending in opposite directions around a central rotation axis 410. The connecting grooves 420 and 430 may have a generally elongated hole-like structure. A connecting pin 220 provided on the guide protrusion 210 of the first air guide member 200 may connect to the upper connecting groove 420 of the pair of connecting grooves 420 and 430, and a connecting pin 320 provided on the guide protrusion 310 of the second air guide member 300 may connect to the lower connecting groove 430.

[0063] When the rotating component rotates in one direction (e.g., clockwise), the upper connecting groove 420 tilts and moves forward, and the lower connecting groove 430 tilts and moves backward. Additionally, the first air guide 200 connected to the upper connecting groove 420 moves linearly forward along the guide hole 111, and the second air guide 300 connected to the lower connecting groove 430 moves linearly backward along the guide hole 121.

[0064] When the rotating member 400 rotates in another direction (e.g., counterclockwise), the upper connecting groove 420 tilts and moves backward, and the lower connecting groove 430 tilts and moves forward. Additionally, the first air guide 200 connected to the upper connecting groove 420 moves linearly backward along the guide hole 111, and the second air guide 300 connected to the lower connecting groove 430 moves linearly forward along the guide hole 121.

[0065] The wing module 500 is mounted on each of the first flow path P1 and the second flow path P2, and is configured to rotate or turn in the left-right direction to control the exhaust direction of the air. The first wing module can be mounted on the first flow path P1, and the second wing module can be mounted on the second flow path P2.

[0066] The wing module 500 may include an upper spacer 510, a lower spacer 520, multiple wings 530, and wing links 540.

[0067] The upper spacer 510 and the lower spacer 520 can be configured to be parallel to each other in a direction perpendicular to the direction of air movement.

[0068] A plurality of wings 530 may be provided between the upper spacer 510 and the lower spacer 520, and each wing 530 may have a rotation axis 531 rotatably connected to the upper spacer 510 and the lower spacer 520.

[0069] The wing link 540 can be rotatably connected to the connecting protrusion 532 of each of the plurality of wings 530. Depending on the left and right movement of the wing link 540, the plurality of wings 530 can rotate in the left or right direction.

[0070] Simultaneously, the wing module 500 installed on the first flow path P1 and the wing module 500 installed on the second flow path P2 can be connected by a connecting rod 550, such that the wing 530 of each wing module 500 can be configured to rotate in the same direction. The connecting rod 550 can be disposed in a structure spanning the internal space S of the pipe frame 100B and is connected to and rotatably driven by the wing actuator 700. The wing actuator 700 can be connected to the first wing module and the second wing module and is configured to adjust the direction of the airflow through the first wing module and the second wing module.

[0071] A guide duct 600 is connected to the front of the air duct 100 and is configured to guide air flowing along a first flow path P1 and a second flow path P2 to an outlet 601, which opens into the vehicle interior. In an embodiment, the guide duct 600 may be an exposed or interior trim piece.

[0072] The guide duct 600 may include a first portion 610, a second upper portion 620 and a second lower portion 630, with a first air passage F1 formed between the second upper portion 620 and the first portion 610 and connected to a first flow path P1, and a second air passage F2 formed between the second lower portion 630 and the first portion 610 and connected to a second flow path P2.

[0073] With the guide pipe 600 connected to the front of the air pipe 100, the first part 610 can cover and seal the internal space S of the pipe frame 100B.

[0074] The outlet 601 can be located at the front of the first portion 610, between the second upper portion 620 and the second lower portion 630. Additionally, the first air passage F1 can be configured to extend downwards, and the second air passage F2 can be configured to extend upwards, such that the first air passage F1 and the second air passage F2 can be connected at the outlet 601.

[0075] An opening 602 may be formed in each of the surfaces of the first air passage F1 and the second air passage F2 of the guide duct 600 that connect to the air duct 100. Air moving along the first flow path P1 and the second flow path P2 can pass through the opening 602 and move along the first air passage F1 and the second air passage F2. In addition, air can be discharged into the vehicle interior from the outlet 601.

[0076] In one embodiment, a protrusion 640 may be provided on the surface of the first portion 610 facing the second lower portion 630, the protrusion 640 protruding from the opening 602 to the second air passage F2.

[0077] The protrusion 640 is composed of a horizontal portion 641 extending horizontally forward from the opening 602 and a vertical portion 642 extending vertically upward at the end of the horizontal portion 641. The protrusion 640 is formed to prevent the Coanda effect from occurring on the surface of the first portion 610. That is, it prevents air moving upward from the second air passage F2 toward the outlet 601 from flowing along the surface of the first portion 610 and into the first air passage F1. Simultaneously, the inner surface of the vertical portion 642 of the second lower portion 630 facing the protrusion 640 is configured as a curved surface 631 to induce the Coanda effect. Therefore, air can flow along the curved surface 631 of the second lower portion 630 and move forward from the outlet 601.

[0078] Furthermore, the protrusion 640 achieves a concealed structure by covering the view of the opening 602 exposed through the outlet 601. Therefore, the opening 602 is covered by the protrusion 640 and is not exposed to the outside. Additionally, since the first portion 610 is exposed through the outlet 601, passengers, including the driver, will perceive the first upper portion 620 and the second lower portion 630 as a continuous structure through the first portion 610 located between these two portions, and therefore cannot visually identify the location where the air is completely exhausted. That is, it achieves the effect of a concealed outlet 601.

[0079] exist Figures 9 to 11The diagram shows the operation of the first air guide 200, the second air guide 300, and the rotator 400 in each mode.

[0080] refer to Figure 9 In normal mode, the rotating member 400 can be rotated by the operation of the actuator 710 and positioned in a vertically perpendicular state between the upper connecting groove 420 and the lower connecting groove 430. Therefore, the first air guide 200 and the second air guide 300 can be positioned at the center of the guide holes 111 and 121, respectively, and the first flow path P1 and the second flow path P2 can be fully opened.

[0081] Air flowing into the internal flow path P0 moves along the first flow path P1 and the second flow path P2, passes through the first air passage F1 and the second air passage F2, and is discharged at the outlet 601 in a substantially horizontal direction to form a frontal wind.

[0082] refer to Figure 10 In the upward mode, the rotating member 400 rotates clockwise by the operation of the actuator 710, and the upper connecting groove 420 tilts and moves forward, while the lower connecting groove 430 tilts and moves backward.

[0083] The first air guide 200 connected to the upper connecting groove 420 is configured to move linearly forward along the guide hole 111 to completely cover or block the first flow path P1, and the second air guide 300 connected to the lower connecting groove 430 is configured to move linearly backward along the guide hole 121 to completely open the second flow path P2.

[0084] Most of the air flowing into the internal flow path P0 moves along the second flow path P2, through the second air passage F2, and is discharged upward at the outlet 601 to create an upwind. Additionally, a portion of the air moves along the first flow path P1 through the gap G, through the first air passage F1, and merges with the upwind at the outlet 601. In this way, in upward mode, sufficient airflow can be ensured by not completely blocking the airflow into the first flow path P1.

[0085] refer to Figure 11 In the downward mode, the rotating member 400 rotates counterclockwise by the operation of the actuator 710, and the upper connecting groove 420 tilts and moves backward, while the lower connecting groove 430 tilts and moves forward.

[0086] The first air guide 200 connected to the upper connecting groove 420 is configured to move linearly backward along the guide hole 111 to fully open the first flow path P1, and the second air guide 300 connected to the lower connecting groove 430 is configured to move linearly forward along the guide hole 121 to fully cover or shield the second flow path P2.

[0087] Most of the air flowing into the internal flow path P0 flows along the first flow path P1, through the first air passage F1, and is discharged downwards at outlet 601 to create a downwind. Additionally, a portion of the air moves along the second flow path P2 through gap G, through the second air passage F2, and merges with the downwind at outlet 601. In this way, in downward mode, sufficient airflow can be ensured by not completely blocking the airflow into the second flow path P2.

[0088] In addition, one or more controllers / processors (not shown) can control the first air guide 200 and the second air guide 300 to slide in the front-to-back direction, and control the amount of air passing through the first flow path 200 and the second flow path 300 respectively, control the rotator 400 to rotate the first air guide 200 and the second air guide 300 in different directions, and / or control the wing actuator 700 to control the wing module 500 to rotate in the left-to-right direction and control the direction of air discharge.

[0089] As described above, the air ventilation device for vehicles according to the embodiments of the present invention achieves the effect of not causing airflow loss by omitting the existing wing for controlling the vertical airflow direction and the wing knob provided on the wing.

[0090] In addition, the wings and wing knobs were omitted to achieve a slimmer profile.

[0091] In addition, since the guide pipes for exhausting air are exposed inside the vehicle and serve a decorative purpose, no separate decoration is needed, thus reducing costs. Furthermore, since the exhaust openings are covered and invisible due to the concealed structure, the aesthetics are improved.

[0092] According to this utility model, an air ventilation device for vehicles can be provided, which can achieve a hidden outlet and does not cause airflow loss because it omits the wing for controlling the vertical airflow direction and the wing knob set on the wing.
