[0003] This invention relates to an automotive vent (ventilator port), and more specifically, to a front wing device for an automotive vent. Background Technology

[0004] Usually in Figure 1 The structure shown forms a ventilation opening (ventilator port) located inside the car. Figure 1 A schematic diagram of the latest slim vent design is shown.

[0005] The front wing 20 is mounted on the front side of the duct housing 10 (in the direction towards the engine hood of the vehicle body), and the rear wing 30 is mounted on the rear side (in the direction towards the driver's seat). The front wing 20 has a structure that allows multiple vertically arranged winglets to rotate in the left-right direction, and the rear wing 30 has a structure that allows multiple winglets (in...) to rotate in the left-right direction. Figure 1 In this slim design, a vertically rotating wing (or a single wing) is incorporated. The front wing 20 and rear wing 30 are assembled within the duct housing 10 to form an air vent assembly. This air vent assembly is ultimately assembled with the instrument panel cover 40 of the vehicle. The instrument panel cover 40 is a design element that forms part of the dashboard in front of the driver's seat. Simultaneously, a duct liner 5 is attached to the front of the duct housing 10 (in the forward direction of the vehicle). Additionally, according to the design, a strip-shaped trim 70 can be attached to the front of the instrument panel cover 40 (i.e., in front of the driver's seat).

[0006] Lateral rotation adjustment of the front wing 20 and vertical rotation adjustment of the rear wing 30 are performed using wing knobs exposed towards the driver's seat. According to one embodiment, the wing knobs include a rear wing knob 50 exposed towards the driver's seat and a front wing knob 60 located within the duct housing 10. In this case, the rear wing knob 50 and the front wing knob 60 can be manufactured as separate parts and assembled within the vent assembly.

[0007] Reference Figure 2A and Figure 2B The structure of the canard 20 is described in more detail. Figure 2A This is a perspective view showing the front wing 20 mounted in the pipe housing 10 as viewed from the driver's seat side, and Figure 2B This is a plan view showing the front wing 20 installed in the pipe housing 10 when viewed from above.

[0008] In the following sections of this specification, as Figure 2A As shown in the lower part, the X direction along the longitudinal side of the vent assembly will be described as the lateral direction, left-right direction, or longitudinal direction; the Y direction between the front and rear of the vehicle will be described as the front-rear direction; and the Z direction along the short side of the vent assembly will be described as the vertical direction or lateral direction. Additionally, in Figure 2A In the diagram, the direction towards the front of the car represents the -Y direction, and the direction towards the rear of the car represents the +Y direction.

[0009] exist Figure 2A In the pipe housing 10, a plurality of front wings 20 are horizontally arranged between a lower spacer 22 located on the lower side and an upper spacer 23 located on the upper side, and can rotate in the left-right direction. Additionally, a rear wing 30 is mounted on the rear side of the pipe housing 10 and can rotate vertically. The user can adjust the lateral rotation of the front wings 20 and the vertical rotation of the rear wing 30 using a wing knob (e.g., rear wing knob 50).

[0010] Therefore, such as Figure 2B As shown, the lower and upper portions of the front wing 20 are rotatably connected to the lower spacer 22 and the upper spacer 23, and the rear wing knob 50 is connected to a central front wing 21. Structurally, since all the front wings 20 are rotatably connected between the lower spacer 22 and the upper spacer 23, when the user moves the rear wing knob 50 in the left-right direction to rotate the central front wing 21, all the front wings 20 rotate in the left-right direction.

[0011] Reference Figure 2C and Figure 2D Describe the connection structure between the wing knob rod 61 and the central forewing 21.

[0012] like Figure 2C As shown, the wing knob lever 61 is configured such that the first lever 62 and the second lever 63 extend from the wing knob lever 61, and the front wing lever 24 of the central front wing 21 is inserted between the first lever 62 and the second lever 63. (Wing knob lever 61 and rear wing knob 50 (see...) Figure 2B ) integrally formed or the wing knob lever is connected to the front wing knob 60 which is connected to the rear wing knob 50 (see Figure 1 ). )

[0013] Due to this structure, such as Figure 2D As shown, when the user moves the rear wing knob 50 in the left and right directions (see...) Figure 2BWhen the rear wing knob is integrated with or separately formed and connected to the rear wing knob, the wing knob rod 61 moves in the left-right direction. Therefore, when the front wing rod 24 of the central front wing 21 moves in the left-right direction, the corresponding front wing 21 rotates in the left-right direction about the rotation axis 26 provided by the hinge shaft 25. Therefore, the lower spacer 22 (see [link to lower part]) rotatably connected to the upper and lower parts of the corresponding central front wing 21... Figure 2A ) and upper spacer 23 (see Figure 2A They move linearly in the left and right directions, and because of their linear movement, all the forewings 20 rotate in the left and right directions. Summary of the Invention

[0014] The present invention aims to provide an improved canard structure to address the conventional problems of canard structures. The conventional problems are: 1) a reduction in wind direction due to cutting the canard when adjusting the wind direction in the left-right direction, wherein the canard is cut to prevent interference; 2) noise caused by gaps due to jet tolerances; and 3) appearance problems and reduction in air volume due to exposed components.

[0015] To address the aforementioned problems, the present invention provides a front wing device located within the duct housing of an automotive vent and configured to rotate in the left-right direction via a wing knob exposed outside the duct housing.

[0017] According to one embodiment, the forewing device may further include: a lower hinge shaft extending from the lower portion of the plurality of forewings; an upper hinge shaft extending from the upper portion of the plurality of forewings; a lower hinge track formed in the lower portion of the pipe housing to guide the lower hinge shaft of the forewing; and an upper hinge track formed in the upper portion of the pipe housing to guide the upper hinge shaft of the forewing.

[0018] According to another embodiment, the forewing assembly may further include: a lower hinge shaft extending from a lower portion of one of the plurality of forewings; an upper hinge shaft extending from an upper portion of the one forewing; a lower hinge rail formed in a lower portion of the pipe housing to guide the lower hinge shaft of the one forewing; an upper hinge rail formed in an upper portion of the pipe housing to guide the upper hinge shaft of the one forewing; and a forewing link rotatably connecting the one forewing to the remaining forewings of the plurality of forewings.

[0019] According to another embodiment, the front wing may include a lower rotating portion formed in the lower portion and rotatably connected to the lower spacer, and an upper rotating portion formed in the upper portion and rotatably connected to the upper spacer. The lower spacer may include a lower rotating connecting portion rotatably connected to the lower rotating portion, and the upper spacer may include an upper rotating connecting portion rotatably connected to the upper rotating portion. The lower rotating connecting portion of the lower spacer may be formed to have no height difference relative to the upper surface of the lower spacer, and the upper rotating connecting portion of the upper spacer may be formed to have no height difference relative to the lower surface of the upper spacer.

[0042] The advantages and features of the present invention and its implementation methods will be clearly understood by referring to the accompanying drawings and the following detailed description. However, the present invention is not limited to the disclosed embodiments and can be implemented in various different forms. These embodiments are provided to fully disclose the present invention to those skilled in the art and to fully explain the scope of the invention, and the scope of the invention is defined by the appended technical solutions. In addition, the terminology used herein is only used to describe embodiments of the invention and is not for limiting purposes. Unless the context clearly indicates otherwise, the singular form also includes the plural form. In addition, it should be understood that the term "comprising" ("including", etc.) when used herein specifies the presence of some stated components, steps, operations and / or elements, but does not exclude the presence or addition of one or more other components, steps, operations and / or elements. In the following, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In the description of embodiments of the present invention, specific descriptions of related well-known technologies or functions will be omitted when they are considered to unnecessarily obscure the essential points of the invention. First Embodiment - Forewing Device with Novel Structure

[0043] For reference Figure 2C and Figure 2D As described, in the conventional structure, since the front wing rod 24 of the central front wing 21 is inserted into the space between the first rod 62 and the second rod 63 of the wing knob rod 61, the first rod 62 and the second rod 63 should extend towards the hinge axis 25 of the central front wing 21. Furthermore, when the central front wing 21 rotates left-right via the wing knob rod 61, the front wing rod 24 moves forward-backward. Therefore, the extension length of the first rod 62 and the second rod 63 should be increased to compensate for the distance difference when the front wing rod 24 moves forward-backward (structurally, when the extension length is short, the wing knob rod 61 is easily separated from the first and second rods). Therefore, when the central front wing 21, connected to the wing knob rod 61, rotates left-right, the central front wing 21 interferes with the first rod 62 and the second rod 63. To prevent interference between the front wing 21 and the wing knob rod 61, such as... Figure 2DAs shown, a cutting space should be provided for the forewing 21. The cutting degree of the cutting space almost exceeds the central axis of rotation 26. However, when the cutting space is set as described above, although the cutting space is set for adjusting the wind direction, the central forewing 21 does not adjust the wind direction because of the cutting space. The wind passes through and is discharged linearly, and therefore, the wind direction adjusted by other wings is affected, resulting in a decrease in the overall wind direction of the forewing 20.

[0044] To address this problem, a first embodiment is proposed. According to this embodiment, a forewing device 200 with a novel structure is provided, such as... Figure 3 As shown.

[0045] Figure 3 A front wing assembly 200 according to a first embodiment is shown. The rear corners (in front of the driver's seat) of the lower portions of a plurality of vertically arranged front wings 210 are rotatably connected to a lower spacer 220, and the rear corners (in front of the driver's seat) of the upper portions of the front wings 210 are rotatably connected to an upper spacer 230. The lower spacer 220 is laterally connected to the rear sides of the lower portions of all the front wings 210, and the upper spacer 230 is laterally connected to the rear sides of the lower portions of all the front wings 210. Additionally, a spacer rod 240 connecting the lower spacer 220 and the upper spacer 230 is provided in the central portion between the lower spacer 220 and the upper spacer 230. The spacer rod 240 is connected to a front wing knob 60 (see...). Figure 1 Furthermore, the front wing knob 60 is connected to the rear wing knob 50 such that when the user moves the rear wing knob 50 in the left-right direction, the spacer rod 240 moves in the left-right direction. Therefore, the lower spacer 220 and the upper spacer 230 connected to the spacer rod 240 are guided by pipe tracks (which will be described below) formed in the upper and lower portions of the pipe housing 10, and move linearly, curvedly, and slidably.

[0046] In this embodiment, only the cut portion C adjacent to the spacer rod 240 is slightly cut into a semi-circular shape on the rear side of the front wing 210. This will be described below.

[0047] Figure 4 This is a lower perspective view, showing the connection between the front wing 210 and the lower spacer 220, and the connection between the lower spacer 220 and the pipe housing 10. Figure 5 This shows a cross-sectional view of the fore-and-aft wing 210. Figure 6 This is a perspective view showing the pipe housing 10 with the front wing 210 and related components removed.

[0048] Reference Figures 4 to 6 Provide a detailed description.

[0049] First, such as Figure 4 As shown, a lower rotating part 211 is provided at the rear corner of the lower portion of the vertically upright front wing 210 (in other words, the driver's seat side), and the rotating connecting part 221 of the lower spacer 220 is connected to the lower rotating part 211. Similarly, as Figure 5 As shown, an upper rotating part 212 is provided at the rear corner of the upper part of the front wing 210, and the rotating connecting part 231 of the upper spacer 230 is connected to the upper rotating part 212.

[0050] The lower spacer 220 is slidably guided in the lateral direction along a lower pipe track 110 formed in the lateral direction on the upper surface of the lower portion of the pipe housing 10. Similarly, the upper spacer 230 is slidably guided in the lateral direction along an upper pipe track 120 formed in the lateral direction on the lower surface of the upper portion of the pipe housing 10. The pipe tracks 110 and 120 may have linear or curved shapes (which will be described below).

[0051] Furthermore, a lower hinge shaft 213 is provided at the substantially central portion of the lower part of the front wing 210, and an upper hinge shaft 214 is provided at the substantially central portion of the upper part of the front wing. Simultaneously, a lower hinge track 130 with a substantially elliptical groove shape is formed in the inner surface of the lower part of the pipe housing 10. Its long diameter is positioned in the transverse direction (front-rear direction) of the pipe housing 10, and its short diameter is positioned in the longitudinal direction (lateral direction). The lower hinge track 130 is formed at a position corresponding to the lower hinge shaft 213 of the front wing 210. Symmetrically, an upper hinge track 140 with a substantially elliptical groove shape is formed in the inner surface of the upper part of the pipe housing 10. Its long diameter is positioned in the transverse direction of the pipe housing 10, and its short diameter is positioned in the longitudinal direction of the pipe housing. The upper hinge track 140 is formed at a position corresponding to the upper hinge shaft 214 of the front wing 210.

[0052] The lower hinge shaft 213 and the upper hinge shaft 214 of the front wing 210 are respectively inserted into the lower hinge rail 130 and the upper hinge rail 140 of the pipe housing 10 and are guided by them respectively.

[0053] like Figure 7A As shown, due to the aforementioned forewing device, the wing knob lever 64 according to the first embodiment only extends to the spacer lever 240 located relatively close to the rear, instead of the longer first lever 62 and second lever 63 as in the conventional wing knob lever 61 (see...). Figure 2CThe rotation axis extends to the forewing as described above. By using a wing knob lever 64 with a new shape and improving the shape of the forewing 210 and the connection method of the lower spacer 220 and the upper spacer 230, there are no wings that require cutting space between the forewings, and all lengths of the wings in the lateral direction (i.e., the width in the longitudinal direction) are the same, so the wind direction can be precisely adjusted. As described above, according to this embodiment, only a few cut portions C are provided on the rear side of the forewings 210 adjacent to the spacer lever 240.

[0054] Due to the above structure, such as Figure 7A and Figure 7B As shown, when the wing knob (e.g., the rear wing knob 50) moves in the left-right direction, all front wings 210 rotate in the left-right direction via the front wing knob 60 connected to the rear wing knob 50 and the wing knob rod 64 connected to or integrally formed with the front wing knob 60 having a new shape. That is, when the rear wing knob 50 moves in the left-right direction, the spacer rod 240 fitted to the wing knob rod 64 moves in the left-right direction, and the lower spacer 220 and upper spacer 230 connected to the spacer rod 240 slide in the left-right direction along the lower pipe track 110 and upper pipe track 120 of the pipe housing 10, and at the same time, the front wings 210 rotate in the left-right direction. In this case, the lower hinge shaft 213 and the upper hinge shaft 214 of the front wing 210 are guided in the front-to-back direction of the vent along the elliptical trajectory of the lower hinge track 130 and the upper hinge track 140 of the duct housing 10, so that the rotation operation of the front wing 210 in the left-to-right direction is performed smoothly.

[0055] As described above, the first embodiment of the present invention has a structure in which the extension length of the wing knob rod 64 is minimized in order to minimize the cutting amount of the front wing 210. Since the spacer rod 240 moves linearly in the left-right direction, there is no distance difference in the front-rear direction.

[0056] Although the rear wing knob 50 is usually designed so that the operation direction is linear left and right, when the rear wing knob 50 is designed to operate along a slightly curved trajectory, the pipe track 110 can also be formed into a corresponding curve, so that the trajectory of the lower spacer and the upper spacer forms a curved shape.

[0057] The hinge shafts 213 and 214 disposed in the lower and upper portions of the front wing 210 and the hinge rails 130 and 140 formed in the inner surfaces of the lower and upper portions of the pipe housing 10 will be further described.

[0058] First, the requirements for articulated rails 130 and 140 are as follows. For example... Figure 5As shown, the rotation operation of the front wing 210 is performed at the lower rotating part 211 and the rotating connecting part 221 of the lower spacer 220 (located at the rear corner of the lower part of the front wing 210, and the upper rotating part 212 and the rotating connecting part 231 of the upper spacer 230) located at the rear corner of the upper part of the front wing 210. In this case, since the lower hinge shaft 213 and the upper hinge shaft 214 of the front wing 210 and the lower hinge rail 130 and the upper hinge rail 140 of the pipe housing 10 are provided, the distance difference in the front-to-back direction caused by the lower spacer 220 and the upper spacer 230 when the front wing 210 rotates can be canceled out.

[0059] The implementation of articulated rails 130 and 140 will be described below.

[0060] Figure 8A and Figure 8B One embodiment of the lower hinged rail 130 is shown, and Figures 9A to 9C Another embodiment of the lower articulated rail 130 is shown. Here, although only the lower articulated rail 130 is described for convenience, the following description will apply to the upper articulated rail 140 in the same manner.

[0061] first, Figure 8A and Figure 8B An embodiment is shown in which the articulated track 130 is formed to extend in the front-rear direction. For example... Figure 8A As shown, when the wind direction is adjusted in the left and right directions relative to the reference standard line N (the major axis of the articulated track 130) within an angle α1 of approximately ±0° to 60°, since the vector direction of the articulated axis 213 of the current wing 210 almost matches the position of the articulated track 130 when it moves in the front and rear directions, no jamming will occur when the articulated axis 213 moves in the front and rear directions along the articulated track 130.

[0062] However, this implementation method has disadvantages. For example... Figure 8B As shown, when the lower spacer 220 moves a large amount to the right (or left) so that the forewing 210 is completely closed, the angle α2 between the articulated track 130 and the forewing 210 (i.e., the difference between the operating vector direction of the rear wing knob 50 and the movement direction of the forewing 210) becomes very large, and the movement of the articulated axis 213 along the articulated track 130 is not smooth, making it difficult to operate the rear wing knob 50 and apply excessive force.

[0063] To mitigate this drawback, the articulated rail 130 is designed as follows: Figure 9AThe shape shown is such that the articulated track 130 is formed as a two-stage structure with a first part 130a having a first tilt angle and a second part 130b having a second tilt angle. In this case, the first angle α3 is in the range of approximately 5° to 25° relative to the reference standard line N, and the second angle α4 is an angle less than 180° - (5° to 25°) relative to the reference standard line N.

[0064] By forming the articulated track 130 into a two-stage structure inclined relative to the reference standard line N, the front wing 210 is used to adjust the wind direction to the left, such as Figure 9A As shown, the angle α5 of the forewing 210 relative to the first part 130a of the articulated track becomes greater than... Figure 8A The angle α1 allows the hinge shaft 213 to slide more smoothly. Additionally, when the front wing 210 is used to adjust the wind direction to the right, such as... Figure 9B As shown, because the angle difference between the canard 210 and the first part 130a of the articulated track is reduced more significantly, the operation becomes smoother, and the canard 210, as... Figure 9C When fully closed as shown, the second part 130b of the articulated track adds a new angle α6 to... Figure 8B At angle α2, the complete closing operation of the forewing 210 becomes smooth, and the load when returning from the fully closed state to the open state is minimized.

[0065] According to the first embodiment of the present invention described above, by minimizing the length of the wing knob lever for adjusting the vent in the left-right direction, the amount of cutting of the wing due to interference with the operating trajectory of the wing knob lever can be minimized, thereby improving wind directionality. As described above, even when the length of the wing knob lever is reduced and the amount of cutting adjacent to the wing is minimized, the wing knob lever will not separate.

[0066] Second implementation – Improvement of noise caused by the gap between the articulated track and the articulated shaft

[0067] In the first embodiment described above, as referenced Figure 6 As described above, multiple pairs of articulated rails are provided in the upper and lower portions of the pipe housing 10, and the number and position of these pairs of articulated rails are the same as the number and position of the front wing 210. Figure 6 A hinged track 130 with an elliptical shape is shown, formed in the inner surface of the lower portion of the pipe housing 10, and a symmetrical hinged track in the inner surface of the upper portion of the pipe housing 10 is identical thereto. Therefore, in the following description, only the hinged track 130 in the lower portion will be described.

[0068] To allow the hinge axis 213 of the front wing 210 to move within the hinge track 130, a small clearance is required. However, this clearance results in noise. Minimizing the clearance between all hinge axes 213 of the front wing 210 and the hinge track 130 requires significant mold modification costs and considerable time, and even when the mold modification is complete, gaps or blockages may still occur due to injection tolerances.

[0069] In the case of the first embodiment described above, since the articulated rails are formed in the pipe housing at positions corresponding to all the front wings, when gaps are generated due to the injection tolerances of the pipe housing, problems arise related to all articulated gaps between the upper pipe rail, the lower pipe rail, and the front wings.

[0070] The second embodiment for solving the problem has a structure that prevents noise from a structure having as many articulated rails as the front wing 210 by providing articulated rails at only one location in each of the upper and lower portions of the pipe housing 10, thereby significantly reducing the number of noise-generating parts.

[0071] like Figure 10 As shown, to implement this structure, a hinge track 135 is formed at only one location in the lower portion of the pipe housing 10, and another hinge track (not shown) is formed at only one location in the upper portion of the pipe housing. Therefore, it is not necessary to provide hinge axes corresponding to the hinge tracks in each of the lower and upper portions of the front wing 210, and as... Figure 11 As shown, the lower hinge shaft 215 is provided only on the forewing 210' corresponding to one hinge track 135. Similarly, the upper hinge shaft 216, which is connected to the upper hinge track (not shown), is formed in the upper part of the forewing 210'.

[0072] However, as Figure 11 As shown, since there is only one articulated track 135, an additional forewing link 250 is provided to organically connect the forewing 210' and the other wings.

[0073] Figure 12 This shows a cross-sectional view of the forewing 210 according to this embodiment, which is cut in the fore-and-aft direction and does not correspond to the articulated track 135. In this embodiment, a forewing link 250 is added. Figure 12 As shown, since the three points of the forewing 210, excluding the lower hinge axis 215 and the upper hinge axis 216, are fixed through three axis points K, L and M, the angle or position of the wing remains unchanged.

[0074] The front wing link 250 is made of a nylon-based material. Although the material of the pipe housing 10 is a paint protective film (PPF) and has dimensional tolerances depending on injection conditions, ambient temperature, etc., the front wing link 250 has almost no dimensional tolerances because it is made of a nylon-based material such as PA6 and is relatively small.

[0075] As described above, according to the second embodiment, since the articulated rail is formed at one location in the upper part of the pipe housing and at one location in the lower part of the pipe housing, the noise generated by the gap between the upper and lower articulated shafts of the front wing and the upper and lower articulated rails of the pipe rail can be significantly eliminated, and the noise-generating factors can be minimized, excluding noise generated by vehicle vibration and air conditioning.

[0076] Third embodiment – ​​Improvement of external design deterioration caused by exposure of the rotating connection of the lower / upper spacer.

[0077] The structure of the first embodiment described above is shown. Figure 4 As shown, the rotating connection 221 of the lower spacer 220 extends from the pipe track 110 (although...) Figure 4 Not shown in the diagram, but the rotating connecting portion 231 of the upper spacer 230 (see...) Figure 5 Similarly, these parts protrude, thus exposing them to the outside of the fan port and contributing to external design degradation. Furthermore, this structure is such that, due to injection tolerances in the lower spacer 220, upper spacer 230, and duct housing 10, blockages or gaps can occur when connected to the duct tracks 110 and 120, making malfunctions or noise more likely. Additionally, the protruding rotating couplings 221 and 231 create resistance to the movement of the exhaust air.

[0078] like Figure 13 and Figure 14 As shown, in order to mitigate this problem, this third embodiment has a structure in which the lower spacer 220' and upper spacer 230' of the hinge structure are not used, so as to minimize the part exposed to the outside, thereby minimizing the noise caused by the gaps generated by the conventional structure.

[0079] refer to Figure 13 To describe the construction of the third embodiment, the rotating connecting portion 221 provided on the conventional lower spacer 220 is not provided (see Figure 4Furthermore, the lower rotating portion 211 of the front wing 210 is rotatably and directly connected to the lower spacer 220', which is manufactured to have a flat surface, and there is no height difference between the upper surfaces of the lower rotating portion 211 and the lower spacer 220'. The upper spacer 230' is in the same situation (its structure is symmetrical to that of the lower spacer). For a clearer description of the structure, reference will be made to the upper and lower structures shown in the third embodiment. Figure 14 (Cross-section view cut in the front-back direction). Figure 14 In the context of Figure 10 and Figure 12 The second embodiment is a view corresponding to the case where only one hinged rail 135 is provided.

[0080] and Figure 5 The implementation differs; in the pipe housing 10, the portions 112 and 114 connecting the lower spacer 220' and the upper spacer 230' are designed with an "L"-shaped structure. Specifically, the pipe tracks 110 and 120 are formed with... Shape (on the bottom) and A shaped (on the upper side) opening slot, instead of... Figure 5 and Figure 6 The “U”-shaped (on the bottom) and “∩”-shaped (on the top) opening slots are shown. Therefore, even in the presence of injection tolerances, the offset edge of these tolerances becomes larger due to the opening slots, thus reducing noise caused by blockage of the lower spacer 220' and the upper spacer 230'.

[0081] Meanwhile, since each of the pipe tracks 110 and 120 has an opening shape with an open side, there is a risk that the lower spacer 220' and upper spacer 230' will separate from them. Therefore, protruding tracks 140a and 140b are formed in the middle of the pipe tracks 110 and 120 to prevent separation. As another example, the protruding tracks 140a and 140b may also be formed on the lower spacer 220' and upper spacer 230' instead of on the pipe tracks 110 and 120.

[0082] Meanwhile, noise may be generated due to the gaps between the lower spacer 220' and the upper spacer 230' and the connected pipe rails 110 and 120, as well as due to the sliding operation of the lower spacer 220' and the upper spacer 230'. When the present invention is designed to minimize the gaps, the two will come into close contact with each other when the sliding operation is performed, thereby generating another noise.

[0083] In order to reduce noise not only when the gap is small but also when the gap is large, a method is added in which tension is applied to each of the lower and upper surfaces of the pipe housing 10 after the upper spacer 230' and the lower spacer 220' are assembled, such that the tension is applied to each of the upper spacer 230' and the lower spacer 220' through the lower and upper surfaces of the pipe housing 10.

[0084] To apply tension to the lower and upper surfaces of the pipe housing 10, a tensioning structure is formed on the upper and / or lower surfaces. This tensioning structure allows the upper and / or lower surfaces of the pipe housing 10 to have vertical elastic forces. Therefore, even when the invention is designed such that there is no gap between the lower spacer 220' and the upper spacer 230' and the pipe tracks 110 and 120 of the pipe housing 10, the pipe tracks 110 and 120 can perform a smooth sliding operation due to the tension on the upper and lower surfaces of the pipe housing 10. This reduces noise caused by gaps. Conversely, even when the gap is large, the gap shifts due to the tension on the upper and lower surfaces of the pipe housing 10, causing the lower spacer 220' and the upper spacer 230' to press against the pipe tracks 110 and 120, thereby reducing noise during sliding operations.

[0085] The tensioning structure can be implemented as, for example, as follows: Figure 15 The pipe housing 10 has slots 150a, 150b, and 150c formed in the front-to-back direction. At least three pairs of slots 150a, 150b, and 150c are formed, with one pair formed in the upper and lower surfaces of the pipe housing 10. These at least three pairs of slots 150a, 150b, and 150c are formed in the lower pipe rail 110 and upper pipe rail 120, which connect to the lower spacer 220' and the upper spacer 230', to prevent leakage of the discharged air.

[0086] Because slots 150a, 150b, and 150c are cut holes in the front-to-back direction, the upper and lower surfaces of the pipe housing 10 receive tension forces (i.e., have vertical elastic forces). To apply the tension forces as described above, such as... Figure 16 ( Figure 16 It shows Figure 14 (An enlarged view of a portion of the protruding track 140a) shows that the dimensions of the lower spacer 220' and the protruding track 140a are designed such that the lower spacer 220' overlaps with the upper surface of the protruding track 140a of the lower pipe track 110 of the pipe housing 10 by approximately 0.1 mm. Even in the case of the upper spacer 230, the present invention is designed according to the above-described situation.

[0087] According to the third embodiment described above, by removing the rotating connecting portion 221 of the lower spacer 220' and the rotating connecting portion 231 of the upper spacer 230', and changing the shape of the pipe tracks 110 and 120 of the pipe housing 10, the protruding portions of the rotating connecting portions of the lower spacer 220' and the upper spacer 230' are removed and not exposed to the outside, thereby eliminating factors that reduce wind movement. Furthermore, when the lower spacer 220' and the upper spacer 230' slide within the pipe tracks 110 and 120, noise generated by the gaps is minimized.

[0088] The following benefits can be obtained from each of the above embodiments of the present invention.

[0089] According to a first embodiment of the present invention, by minimizing the length of the wing knob lever for adjusting the vents in the left-right direction, the amount of cutting of the forewing caused by interference with the operating trajectory of the wing knob lever can be minimized, thereby improving wind directionality. As described above, the reduced length of the wing knob lever minimizes the amount of cutting adjacent to the forewing, and the wing knob lever does not separate.

[0090] Furthermore, according to the second embodiment, since the articulated rail is formed at one location in the upper part of the pipe housing and at one location in the lower part of the pipe housing, the noise generated by the gap between the upper and lower articulated shafts of the front wing and the upper and lower articulated rails of the pipe housing can be significantly eliminated, and the noise-generating factors can be minimized, excluding noise generated by vehicle vibration and air conditioning.

[0091] Furthermore, according to the third embodiment, the protruding portions of the rotating joints of the lower spacer and the upper spacer are removed and not exposed to the outside, thereby improving the external design quality and eliminating factors that reduce wind movement. Additionally, when the lower and upper spacers slide slidably in the duct track, noise generated due to the gap is minimized.

[0092] As described above, the structure and operation of the present invention have been described in detail with reference to the accompanying drawings. However, these are merely examples, and those skilled in the art can make various changes and modifications within the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above-described embodiments, but should be defined by the appended technical solutions.
