Description

Technical Field

[0001] This disclosure relates to a vehicle ventilation opening. Background Technology

[0002] The vehicle is equipped with an air conditioner for regulating interior air temperature and ventilation. This air conditioner produces warm air to keep the vehicle interior warm in winter and cool air to keep the vehicle interior cool in summer.

[0003] An air conditioner may include: an air conditioning unit that adjusts air temperature by exchanging heat between air and a heat exchange medium; and a blower unit that supplies air to the air conditioning unit. In a vehicle, the conditioned air may be supplied to the interior via vents connected to the air conditioning unit. The vents are located within the dashboard, and their outlets are exposed to the passenger compartment via openings formed in the dashboard.

[0004] Recently, in line with the trend of thinner cockpit modules in vehicles, research is also being conducted on thinning the outlets of air vents.

[0005] However, the problem with traditional vents is that they increase manufacturing costs because they use many components to prevent the loss of airflow to the passenger compartment when the vents are made thinner.

[0006] Furthermore, the operating mechanism can be complex due to the large number of components in the vent. Therefore, when components fail, the time required for disassembly and replacement increases. Summary of the Invention

[0007] This disclosure aims to provide an improved vehicle air vent that simplifies the operating mechanism by reducing the number of components used to adjust the airflow while slimming the outlet.

[0008] According to one aspect of this disclosure, a vehicle vent is provided, the vehicle vent including: a duct housing; a first wing assembly disposed on the outlet side of the duct housing; a second wing assembly disposed in the duct housing; and a knob coupled to the first wing assembly, wherein the knob includes a knob pin movably disposed in the first wing assembly.

[0009] The vehicle vent may include a guide assembly that is coupled to the first wing assembly and rotates in coordination with the movement of the knob.

[0010] The guiding assembly may include: a guiding box disposed within the pipe housing and guiding the flow of air; a first link connected to an end of the guiding box and disposed outside the pipe housing; and a second link connecting the first link to the first wing assembly, wherein the second link can rotate as the first wing assembly rotates together with the knob.

[0011] The rotation directions of the first link and the second link can be opposite to each other.

[0012] The pipe housing may include a stop that is obliquely disposed on the outer surface of the pipe housing and contacts the first connecting rod, and the rotation of the guide box can be stopped when the first connecting rod contacts the stop.

[0013] The first wing assembly may include: a first wing body having a first through hole formed therein; and a second wing body connected to the first wing body, having a second through hole communicating with the first through hole formed therein.

[0014] The width of the first through hole and the width of the second through hole can be greater than the width of the knob pin.

[0015] The knob may further include: a knob body supporting the knob pin, connected to the second wing body, and disposed outside the pipe housing; and a connector connected to each of the knob pin and the second wing body, and moving in coordination with the movement of the knob pin.

[0016] The knob pin may include a sliding groove recessed in the knob pin, thereby enabling it to slide within the first through hole.

[0017] The first wing body may include a sliding protrusion that is connected to the sliding groove and supports the knob pin so that it can move in a sliding manner.

[0018] The vehicle vent may further include a guide block disposed on the outlet side of the duct housing, wherein the guide block may include: a first inclined surface arranged to be inclined upward from the knob toward the duct housing; and a second inclined surface arranged to be inclined downward from the knob toward the duct housing.

[0019] The vehicle ventilation opening may include a support housing disposed on the inlet side of the duct housing and supporting the guide box.

[0020] The guide box may include flanges projecting from each of its two ends toward the inner surface of the pipe housing.

[0021] When the guide box rotates in coordination with the rotation of the knob, the flange can contact the inner surface of the pipe housing. Attached Figure Description

[0055] The vehicle ventilation vent 1 includes a duct housing 100, a first wing assembly 200, a guide assembly 300, a second wing assembly 400, a knob 500, a guide block 600, and a support housing 700.

[0056] Figure 4 This is a diagram illustrating a pipe housing according to an embodiment of the present disclosure, and Figure 5 It is along Figure 4 A cross-sectional view cut by line AA.

[0057] Reference Figures 1 to 5 The duct housing 100 can guide air regulated by an air conditioner (not shown) to be discharged into the passenger compartment. The duct housing 100 may have a hollow rectangular parallelogram shape to form an inlet 100a through which air flows and an outlet 100b for the exhaust air, but is not limited thereto.

[0058] The pipe shell 100 includes a first pipe body 110 and a second pipe body 120.

[0059] The first duct body 110 can guide air supplied from an air conditioner (not shown) in the direction toward the passenger compartment. An inlet 100a through which the air supplied from the air conditioner (not shown) can flow can be arranged in the first duct body 110.

[0060] The first pipe body 110 may include a stop 111 and a fixing groove 112.

[0061] A stop 111 is disposed on the outer surface of the pipe housing 100. The stop 111 is arranged to be inclined in the direction from the inlet 100a toward the outlet 100b. The stop 111 may be disposed above and below the first link 320, which will be described below, in the Y direction. The stop 111 may contact the first link 320 to stop the rotation of the first link 320.

[0062] The fixing groove 112 can be arranged in each of the two ends of the first pipe body 110. The fixing groove 112 can be connected to a part of the support housing 700 and can support a part of the support housing 700.

[0063] The second pipe body 120 is configured such that its end in the Y direction forms a step with the first pipe body 110. An outlet 100b, which allows air flowing through the inlet 100a to be discharged, can be arranged in the second pipe body 120.

[0064] The second pipe body 120 may include a first hook groove 121.

[0065] The first hook groove 121 can be arranged in each of the upper and lower surfaces of the end of the second pipe body 120 in the Z direction on the outlet 100b side. A plurality of first hook grooves 121 can be arranged to be spaced apart from each other in the X direction. The first hook groove 121 can be engaged with the second hook protrusion 610 of the guide block 600.

[0066] Figure 6 This is an exploded perspective view showing a first wing assembly according to an embodiment of the present disclosure, and Figure 7 This is a cross-sectional view showing a first wing assembly according to an embodiment of the present disclosure.

[0067] Reference Figure 6 and Figure 7 The first wing assembly 200 is arranged on the outlet 100b side of the duct housing 100. The first wing assembly 200 can be rotatably connected to a portion of the guide assembly 300. The first wing assembly 200 can be connected to a knob 500. Therefore, the first wing assembly 200 can be rotated up or down by means of the knob 500 to determine the direction of airflow toward the passenger compartment.

[0068] The first wing assembly 200 may include a first wing body 210 and a second wing body 220.

[0069] The first wing body 210 can be arranged along the X direction. The first wing body 210 can rotate in coordination with the vertical movement of the knob 500.

[0070] The first wing body 210 may include a second hook groove 211, a first through hole 212, a sliding protrusion 213, a first connecting protrusion 214, and a second connecting protrusion 215.

[0071] The second hook groove 211 is recessed in a surface of the first wing body 210 in the Y direction. A plurality of second hook grooves 211 can be arranged to be spaced apart from each other in the X direction.

[0072] The first through hole 212 can be arranged among a plurality of second hook slots 211. The first through hole 212 can pass through a surface of the first wing body 210 in the direction from the outlet 100b to the inlet 100a (Y direction). When the knob 500 is connected to the first wing assembly 200, a portion of the knob 500 can be arranged in the first through hole 212.

[0073] like Figure 7 As shown, the sliding protrusion 213 can protrude from the inner surface of the first wing body 210 along the Y direction.

[0074] The sliding protrusion 213 can be engaged with a portion of the knob 500 disposed in the first through hole 212. The sliding protrusion 213 can support this portion of the knob 500 so that the knob 500 can slide in the X direction.

[0075] The first connecting protrusion 214 may be disposed on the end of the first wing body 210 in the Y direction. The first connecting protrusion 214 may have a hollow cylindrical shape. The interior of the first connecting protrusion 214 may have a shape corresponding to a part of the shape of the second link 330, so that the first connecting protrusion 214 is connected to the second link 330.

[0076] The second connecting protrusion 215 may be arranged on the end of the first wing body 210 in the Y direction. The second connecting protrusion 215 may be arranged on the side opposite to the portion where the first connecting protrusion 214 is arranged.

[0077] The second connecting protrusion 215 may have a cylindrical shape. The second connecting protrusion 215 may be connected to a portion of the guide block 600. Therefore, the first wing assembly 200 may be fixed to the guide block 600.

[0078] The second wing body 220 is connected to the first wing body 210. The second wing body 220 can be connected to the knob 500 and can guide the movement of the knob 500 in the X direction.

[0079] The second wing body 220 may include a first hook protrusion 221 and a second through hole 222.

[0080] The first hook protrusion 221 can be connected to the second hook groove 211. The first hook protrusion 221 can be connected to the second hook groove 211, thereby allowing the second wing body 220 to be connected to the first wing body 210. A plurality of first hook protrusions 221 can be arranged to be spaced apart from each other in the X direction.

[0081] The second through hole 222 can be arranged among the plurality of first hook protrusions 221. The second through hole 222 can pass through one surface of the second wing body 220 in the direction from the outlet 100b to the inlet 100a (Y direction). When the second wing body 220 is connected to the first wing body 210, the first through hole 212 and the second through hole 222 can communicate with each other. Therefore, when the knob 500 is connected to the first wing assembly 200, a portion of the knob 500 can be arranged in the first through hole 212 and the second through hole 222.

[0082] Figure 8 This is an exploded perspective view showing a guide component according to an embodiment of the present disclosure. Figure 9 This is a diagram illustrating aspects of the connection between the first wing assembly, the guide assembly, and the knob according to an embodiment of the present disclosure, and Figure 10 This is a diagram illustrating an aspect of the first link and the second link rotating in opposite directions according to an embodiment of the present disclosure.

[0083] Reference Figures 8 to 10 The guide assembly 300 can be connected to the first wing assembly 200. When the guide assembly 300 is connected to the first wing assembly 200, the guide assembly 300 can rotate in coordination with the movement of the knob 500. The guide assembly 300 can guide the flow of air that enters the pipe housing 100 via the inlet 100a.

[0084] The guide assembly 300 includes a guide box 310, a first link 320, and a second link 330.

[0085] The guide box 310 can be arranged in the pipe housing 100. More specifically, the guide box 310 can be arranged in the support housing 700, which is arranged in the pipe housing 100.

[0086] The guide box 310 can rotate in coordination with the rotation of the knob 500 in the Y direction. Furthermore, as... Figure 10 As shown, the guide box 310 can rotate together with the first link 320 about the axial protrusion 311.

[0087] For example, the guide box 310 can rotate clockwise together with the first link 320 about the axial protrusion 311. Furthermore, the guide box 310 can rotate counterclockwise together with the first link 320 about the axial protrusion 311.

[0088] The guide box 310 may include a shaft protrusion 311, a first flange 312, and a second flange 313.

[0089] A shaft protrusion 311 may be disposed on each of the two ends of the guide box 310. The shaft protrusion 311 may be disposed in the space formed by the intersecting fixing grooves 112 and a portion of the support housing 700. The guide box 310 and the first connecting rod 320 may be connected by means of the shaft protrusion 311.

[0090] The first flange 312 and the second flange 313 have a shape that protrudes from the two ends of the guide box 310 in the Y direction toward the inner surface of the pipe housing 100.

[0091] The first flange 312 can protrude upward toward the inner surface of the pipe housing 100. When the guide box 310 rotates in coordination with the rotation of the knob 500, the first flange 312 can contact the upper inner surface of the pipe housing 100. Therefore, the first flange 312 can prevent air flowing into the pipe housing 100 from leaking to the upper outside of the guide box 310.

[0092] The second flange 313 can protrude downward toward the inner surface of the pipe housing 100. When the guide box 310 rotates in coordination with the rotation of the knob 500, the second flange 313 can contact the lower inner surface of the pipe housing 100. Therefore, the second flange 313 can prevent air flowing into the pipe housing 100 from leaking to the lower outside of the guide box 310.

[0093] The first link 320 can be connected to the shaft protrusion 311 of the guide box 310. The first link 320 can rotate together with the guide box 310 in coordination with the rotation of the knob 500. The first link 320 can determine the angle of rotation of the guide box 310.

[0094] The first link 320 may include a first link body 321 and a guide hole 322.

[0095] The first connecting rod body 321 is connected to the shaft protrusion 311. The first connecting rod body 321 can be arranged outside the pipe housing 100. The first connecting rod body 321 can rotate together with the guide box 310 about the rotation center of the shaft protrusion 311. When the first connecting rod body 321 contacts the stop member 111, the rotation of the first connecting rod body 321 can be stopped. The rotation range of the first connecting rod body 321 can be determined by the tilt angle of the stop member 111.

[0096] A guide hole 322 may be disposed in a portion of the first connecting rod body 321. The guide hole 322 may have a hole shape that extends in the arrangement direction of the first connecting rod body 321. A portion of the second connecting rod 330 may be movably disposed in the guide hole 322.

[0097] The second link 330 can be connected to each of the first link 320 and the first wing assembly 200 to connect the first link 320 and the first wing assembly 200.

[0098] The second link 330 may include a second link body 331, a rotating protrusion 332, and a connecting pin 333.

[0099] The second link 331 can rotate in the same direction as the rotation of the first wing assembly 200 and the knob 500, in coordination with the movement of the knob 500.

[0100] A rotating protrusion 332 protrudes from a portion of the second connecting rod body 331. The rotating protrusion 332 is movably arranged in the guide hole 322. More specifically, as... Figure 10 As shown, the rotating protrusion 332 can be movably arranged between region A and region B of the guide hole 322.

[0101] Therefore, the rotating protrusion 332 can move along the guide hole 322, thereby orienting the second link body 331 and the first link body 321 to the same point. In this case, the first link body 321 and the second link body 331 rotate about the rotating protrusion 332 in different directions.

[0102] A connecting pin 333 can be disposed on one end of the second connecting rod body 331. The connecting pin 333 can engage with a hole formed in the first connecting protrusion 214. The connecting pin 333 connects the second connecting rod body 331 and the first wing assembly 200. When the first wing assembly 200 rotates together with the knob 500, the connecting pin 333 can rotate in the same direction as the rotation of the first wing assembly 200. Due to the connecting pin 333, the second connecting rod body 331 can rotate in the same direction as the rotation of the first wing assembly 200.

[0103] Figure 11 This is an exploded perspective view showing the second wing assembly according to an embodiment of the present disclosure, and Figure 12 This is a cross-sectional view showing an aspect of the second wing assembly arranged in the pipe housing according to an embodiment of the present disclosure.

[0104] Reference Figure 11 and Figure 12 The second wing assembly 400 is disposed within the pipe housing 100. The second wing assembly 400 can be coupled to a portion of the knob 500 and can support that portion of the knob 500. The second wing assembly 400 can rotate in coordination with the movement of the knob 500.

[0105] The second wing assembly 400 may include a support block 410, a third wing body 420, and a fourth wing body 430.

[0106] The support block 410 can be arranged within the pipe housing 100. More specifically, such as... Figure 12As shown, the support block 410 can be arranged on the stepped portion of the first pipe body 110 and can be supported by the first pipe body 110. The support block 410 can rotatably support the third wing body 420 and the fourth wing body 430.

[0107] The third wing body 420 can be rotatably connected to the support block 410.

[0108] The third wing body 420 may include a rotation axis 421.

[0109] The rotation shaft 421 can be arranged along the Z direction. The rotation shaft 421 can be formed in a cylindrical shape. The rotation shaft 421 can be connected to a portion of the knob 500 and can support that portion of the knob 500. When the knob 500 moves left or right in the X direction, the rotation shaft 421 can rotate together with that portion of the knob 500 in coordination with its lateral movement. When the rotation shaft 421 rotates, the third wing body 420 rotates.

[0110] The fourth wing body 430 can be rotatably connected to the support block 410. When the rotation axis 421 rotates, the fourth wing body 430 can rotate in the same direction as the rotation direction of the third wing body 420.

[0111] Figure 13 This is an exploded perspective view showing a knob according to an embodiment of the present disclosure. Figure 14 This is a cross-sectional view showing the state in which the knob is connected to the first wing assembly according to an embodiment of the present disclosure. Figure 15 This is a diagram illustrating an aspect of the connection between the knob and the first wing assembly according to an embodiment of the present disclosure, and Figure 16 This is a diagram illustrating an aspect of the connection between the connector and the second wing assembly according to an embodiment of the present disclosure.

[0112] Reference Figures 13 to 16 Knob 500 is connected to each of the first wing assembly 200 and the second wing assembly 400. Knob 500 can control the movement of the first wing assembly 200 and the second wing assembly 400.

[0113] The knob 500 includes a knob body 510, a knob pin 520, and a connector 530.

[0114] The knob body 510 can be connected to the second wing body 220. With the knob body 510 connected to the second wing body 220, the knob body 510 can be arranged outside the pipe housing 100.

[0115] The knob body 510 can be movably arranged on the second wing body 220 in a sliding manner in the X direction. The knob body 510 can control the vertical rotation of the first wing body 210 and the lateral movement of the second wing body 220.

[0116] The knob pin 520 can be connected to the knob body 510. The knob pin 520 can be movably arranged in the first wing assembly 200. More specifically, the knob pin 520 can be arranged in the first through hole 212. Therefore, the knob pin 520 can move in the first through hole 212 in a sliding manner in the X direction. In addition, the knob pin 520 can move upward or downward in coordination with the vertical movement of the knob body 510. The first wing assembly 200 can move upward or downward by means of the knob pin 520.

[0117] The knob pin 520 may include a sliding groove 521.

[0118] A sliding groove 521 can be recessed into one surface of the knob pin 520 toward the interior of the knob pin 520. The sliding groove 521 can be movably supported in the sliding protrusion 213. Due to the sliding groove 521, the knob pin 520 can move in the first through hole 212 in a sliding manner in the X direction.

[0119] Connector 530 can be coupled to each of knob pin 520 and second wing assembly 400. With connector 530 coupled to knob pin 520, connector 530 can be disposed outside the first wing body 210.

[0120] The connector 530 can be connected to and supported by the rotating shaft 421. A protruding rib 531 can be formed in the part of the connector 530 that is connected to the rotating shaft 421. The state in which the connector 530 is supported by the rotating shaft 421 can be stably maintained by the protruding rib 531.

[0121] Connector 530 can move in coordination with the movement of knob pin 520.

[0122] For example, when the knob body 510 is rotated up or down, the connector 530 can slide in the direction of the rotation axis 421.

[0123] For example, when the knob body 510 moves to the left or right, the connector 530 can rotate the third wing body 420 and the fourth wing body 430 while moving together with the knob pin 520.

[0124] like Figure 15 As shown, the first width W1 of the first through hole 212 and the second width W2 of the second through hole 222 can be greater than the third width W3 of the knob pin 520 and the fourth width W4 of the connector 530. Therefore, the knob pin 520 and the connector 530 can slide in the first through hole 212 and the second through hole 222 in coordination with the movement of the knob body 510 in the X direction.

[0125] Figure 17AThis is a diagram illustrating a guide block according to an embodiment of the present disclosure, and Figure 17B It is along Figure 17A A cross-sectional view of line BB.

[0126] Reference Figure 1 , Figure 3 , Figure 17A and Figure 17B The guide block 600 can be arranged on the outlet 100b side of the pipe housing 100. The guide block 600 can be arranged between the pipe housing 100 and the first wing assembly 200. Together with the first wing assembly 200, the guide block 600 can set the direction of movement of the air discharged from the pipe housing 100 via the outlet 100b.

[0127] The guide block 600 may include a second hook protrusion 610, a first inclined surface 620, a second inclined surface 630, a first extension protrusion 640, and a second extension protrusion 650.

[0128] A second hook protrusion 610 may be formed on each of the upper and lower surfaces of the guide block 600. A plurality of second hook protrusions 610 may be arranged to be spaced apart from each other in the X direction. The second hook protrusions 610 may engage with a first hook groove 121 of the pipe housing 100. The second hook protrusions 610 may engage with the first hook groove 121 so that the guide block 600 can be secured to the pipe housing 100.

[0129] The first inclined surface 620 can be arranged to slope upwards from the knob 500 toward the pipe housing 100. Therefore, as Figure 20A As shown, the first inclined surface 620 may be arranged at a first angle θ1 relative to the inner upper surface of the pipe housing 100.

[0130] When the first wing assembly 200 rotates downward in coordination with the movement of the knob 500, the first inclined surface 620, together with the first wing body 210, can guide air toward the lower side of the passenger compartment.

[0131] The second inclined surface 630 can be arranged to slope downwards from the knob 500 toward the pipe housing 100. Therefore, as... Figure 20A As shown, the second inclined surface 630 can be arranged at a second angle θ2 relative to the inner lower surface of the pipe housing 100.

[0132] When the first wing assembly 200 rotates upward in coordination with the movement of the knob 500, the second inclined surface 630, together with the first wing body 210, can guide air toward the upper side of the passenger compartment.

[0133] A first extension protrusion 640 may be disposed on the end of the guide block 600. The first extension protrusion 640 may be connected to the connecting pin 333 of the guide assembly 300 via a third through hole 641, which is formed to pass through one side of the first extension protrusion 640. Therefore, the connection between the guide block 600 and the pipe housing 100 can be stably maintained.

[0134] A second extension protrusion 650 may be disposed on an end of the guide block 600. The second extension protrusion 650 may include a connecting groove 651, which is recessed inward from one side of the second extension protrusion 650 in the X direction. The connecting groove 651 may engage with a second connecting protrusion 215 of the first wing body 210. The connecting groove 651 may rotatably support the second connecting protrusion 215.

[0135] Figure 18 This is a diagram illustrating a support housing according to an embodiment of the present disclosure, and Figure 19 This is a diagram illustrating an aspect of the connection between the guide box and the support housing according to an embodiment of the present disclosure.

[0136] Reference Figure 18 and Figure 19 The support housing 700 can be arranged on the inlet 100a side of the pipe housing 100. With the support housing 700 arranged in the pipe housing 100, the support housing 700 can support the guide box 310.

[0137] The support housing 700 may include a fixing protrusion 710 and a support groove 720.

[0138] A fixing protrusion 710 protrudes from each of the two ends of the support housing 700. The fixing protrusion 710 may be formed with a shape corresponding to the outer surface of the fixing groove 112 of the pipe housing 100. The fixing protrusion 710 may engage with the fixing groove 112. The engagement of the fixing protrusion 710 with the fixing groove 112 can stably maintain the connection between the support housing 700 and the pipe housing 100.

[0139] The support groove 720 can be formed recessed inward along the Y direction from a portion of the fixing protrusion 710. The support groove 720 can have a hemispherical shape. Figure 19 As shown, the support groove 720 can rotatably support a portion of the shaft protrusion 311 of the guide assembly 300.

[0140] In the vehicle vent 1 according to this embodiment, the connecting rods 320 and 330 can be arranged outside the duct housing 100, and the guide box 310 can be rotated. Therefore, the need to arrange many components for setting the airflow direction in the duct housing 100 can be reduced. Therefore, the time required to manufacture the vehicle vent 1 can be reduced, and the manufacturing cost can be reduced.

[0141] Furthermore, since the vehicle vent 1 according to this embodiment does not have a complex internal structure compared to conventional vents, the time required to replace and repair the components constituting the vehicle vent 1 can be reduced.

[0142] The process of supplying air from an air conditioner (not shown) to the lower part of the passenger compartment via vehicle vent 1 will be described below.

[0143] Figure 20A This is a cross-sectional view showing the interior of a vehicle ventilation opening according to an embodiment of the present disclosure, and Figure 20B This is a diagram illustrating aspects of the rotation of the knob, the first wing assembly, and the guide assembly according to an embodiment of the present disclosure.

[0144] Reference Figure 20A and Figure 20B The vehicle ventilation vent 1 can supply air to the lower side of the passenger compartment by moving the knob 500.

[0145] like Figure 20A As shown, in the default state where the components of the vehicle vent 1 do not move up or down, the knob 500 and the first wing assembly 200 are maintained in a state where they do not rotate around the second connecting protrusion 215. Therefore, the guide box 310, the first link 320, and the second link 330 also maintain a state where the guide box 310, the first link 320, and the second link 330 do not rotate according to the movement of the knob 500.

[0146] like Figure 10 and Figure 20B As shown, when the knob body 510 is moved downward by the user, the first wing assembly 200 rotates about the second connecting protrusion 215 via the knob pin 520 connected to the knob body 510. More specifically, as the knob pin 520 rotates upward about the second connecting protrusion 215, the first wing body 210 rotates together with the knob pin 520 toward the upper interior of the pipe housing 100.

[0147] During this process, connector 530 moves on rotating shaft 421 in a sliding manner in the Z direction and is positioned on the upper side of rotating shaft 421.

[0148] Therefore, the first wing body 210, together with the upper inner surface of the duct housing 100, has an inclination angle of first angle θ1 approaching the first inclined surface 620 of the guide block 600. Furthermore, the first wing body 210 and the first inclined surface 620 together form a guide path that guides air flowing from inlet 100a towards outlet 100b towards the lower side of the passenger compartment.

[0149] At the same time, the second link 331 connected to the first wing assembly 200 rotates together with the first wing assembly 200 in coordination with the movement of the first wing assembly 200.

[0150] As the second link 331 rotates, the rotating protrusion 332 moves along the second link 331 and simultaneously moves within the guide hole 322. More specifically, the rotating protrusion 332 moves from region A to region B of the guide hole 322.

[0151] Therefore, the rotating protrusion 332 reaches region B and contacts one of the surfaces of the guide hole 322 arranged in region B. The rotating protrusion 332, in contact with one surface of the guide hole 322, guides the first link 321 toward the same point as the second link 331. More specifically, in the first link 321, the portion with the guide hole 322 moves to the point to which the rotating protrusion 332 moves. Therefore, the first link 321 and the second link 331 rotate in different directions.

[0152] When the first connecting rod 321 rotates in a direction different from that of the second connecting rod 331, the first connecting rod 321 and the guide box 310 rotate about the axial protrusion 311. The guide box 310 rotates toward the upper interior of the pipe housing 100.

[0153] When the guide box 310 rotates, the first flange 312 contacts the inner upper surface of the pipe housing 100. Therefore, the first flange 312 prevents air from leaking to the upper outside of the guide box 310.

[0154] Air passing through inlet 100a can flow through guide box 310 toward the upper interior of duct housing 100, through the guide path formed by first wing body 210 and first inclined surface 620, and be discharged toward the lower side of passenger compartment.

[0155] In the implementation method Figure 20B The illustration shows air being supplied to the lower side of the passenger compartment via vehicle vent 1, but this disclosure is not limited thereto. For example, when knob 500 is rotated upwards, air can be discharged to the upper side of the passenger compartment.

[0156] According to embodiments of this disclosure, the vertical wind direction is determined by a connecting rod arranged outside the duct housing. Therefore, the number of components in the duct housing used for guiding the wind direction is reduced, thereby lowering manufacturing costs.

[0157] Furthermore, according to embodiments of this disclosure, since the number of components used to adjust the airflow direction is reduced, the time required to disassemble and replace components when they are damaged can be reduced compared to conventional vents.

[0158] While this disclosure has been described above with reference to exemplary embodiments, those skilled in the art will understand that various modifications and alterations can be made to this disclosure without departing from the spirit and scope of this disclosure as defined in the appended claims. Furthermore, it should be construed that differences relating to modifications and alterations fall within the scope of this disclosure as defined in the appended claims.
