Description

Technology Field

[0001] The present invention relates to a slim air vent for vehicles, and more specifically, to a technology for a slim air vent for vehicles in which the vertical height is reduced while satisfying performance standards regarding wind direction and airflow. Background Technology

[0002] Generally, the dashboard of a vehicle is equipped with an air vent to discharge cold or warm air into the cabin.

[0003] The air vent is equipped with an inner wing that rotates left and right and an outer wing that rotates up and down, and serves to discharge cold or warm air generated by the air conditioner into the cabin in the left-right and up-down directions through the rotation of the inner and outer wings.

[0004] However, conventional air vents have a structure in which multiple outer wings that rotate vertically protrude from the outside of the duct through which air moves, and are stacked with vertical spacing. When viewed from inside a vehicle, the vertical length is long (height is high) due to the multiple outer wings protruding from the outside of the duct and stacked vertically, while the horizontal length is formed to be equal to the vertical length. Consequently, conventional air vents have the disadvantage of being large and clunky in appearance, making it difficult to pursue a smart or premium image.

[0005] In addition, conventional air vents have the disadvantage of poor aesthetics because the outer wing protrudes outside the duct and is exposed to the interior.

[0006] In addition, conventional air vents have the disadvantage that the cross-sectional area of ​​the outlet through which air is discharged into the room changes depending on the vertical rotation of the outer wing, and as a result, the airflow volume of the air discharged into the room changes, making it impossible to maintain a constant airflow volume, which in turn reduces the performance of the air vent.

[0007] The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. Prior art literature

[0039] Hereinafter, a slim air vent for a vehicle according to a preferred embodiment of the present invention will be examined with reference to the attached drawings.

[0040] As illustrated in FIGS. 1 to 9, the slim air vent for a vehicle according to the present invention comprises: a duct (100) that guides the flow of air into the interior; a plurality of inner wings (200) that are rotatably coupled to the duct (100) to guide the discharge direction of air in the left and right directions; spacers (300) fixedly coupled to the left and right sides of the duct (100); an outer wing (400) located at the rear of the inner wing (200) and having both left and right ends rotatably coupled to the spacers (300) in the up and down directions; a support wing (500) that is rotatably connected to the front end of the outer wing (400), has both left and right ends rotatably coupled to the spacers (300) in the up and down directions, and whose length varies when the outer wing (400) rotates; a knob (600) coupled to connect the inner wing (200) and the outer wing (400); and a knob (600) that penetrates the knob (600) in the left and right directions and the knob (600) It includes a knob pin (700) that rotates together with the knob (600) when rotating in the up-and-down direction and guides the movement of the knob (600) when the knob (600) moves in the left-and-right direction, and a link mechanism (800) that connects one end of the knob pin (700) to the outer wing (400) and operates to rotate the outer wing (400) and the support wing (700) in the up-and-down direction when the knob pin (700) rotates in accordance with the up-and-down rotation of the knob (700).

[0041] The slim air vent according to the present invention is configured such that the inner wing (200), the outer wing (400), and the support wing (500) are all positioned to be inserted inside the duct (100). Compared to a conventional air vent having a structure in which multiple outer wings protrude from the outside of the duct and are stacked vertically, the vertical height of the air vent can be significantly reduced, thereby enabling the configuration of a slim air vent and enabling the realization of a smart image and a premium image, which has the advantage of being applicable to autonomous vehicles with a smart image.

[0042] In addition, since the inner wing (200), outer wing (400), and support wing (500) are all located inside the duct (100), there is an advantage in that a hidden effect can be achieved and the aesthetic appearance can be improved.

[0043] The inner wings (200) are composed of multiple units arranged on the left and right sides, and the multiple inner wings (200) are connected integrally through a linkage (210) connected at the top and bottom. The linkage (210) is rotatably connected to the duct (100), so that when any one of the multiple inner wings (200) rotates to the left or right, the remaining inner wings (200) connected through the linkage (210) also rotate to the left or right simultaneously.

[0044] The inner wing (200) and the outer wing (400) can be named the vertical wing and the horizontal wing, respectively, depending on the direction in which they are installed.

[0045] According to the present invention, spacers (300) are fixedly connected to the left and right sides of the duct (100) so as to face the sides of the outer wing (400).

[0046] The spacer (300) also serves to prevent air leakage by blocking unnecessary gaps between the side of the duct (100) and the side of the outer wing (400), thereby eliminating whistle noise caused by leakage.

[0047] The outer wing (400) includes an upper outer wing (410) and a lower outer wing (420) that are spaced apart vertically.

[0048] Guide protrusions (411, 421) are formed on the left and right sides of the upper outer wing (410) and lower outer wing (420), respectively, and in the spacer (300), a first guide hole (310) and a second guide hole (320) are formed so as to be spaced apart vertically, extending along the rotation radius of the upper outer wing (410) and the rotation radius of the lower outer wing (420), respectively, into which the guide protrusions (411, 421) are inserted and moved.

[0049] The guide projections (411, 421) and the first and second guide holes (310, 320) serve to guide the vertical rotation of the outer wing (400), and furthermore, they also serve to connect the duct (100) and the outer wing (400) through the spacer (300), thereby making the connection structure of the outer wing (400) more robust.

[0050] Hinge projections (412, 422) are formed to protrude left and right on the rear ends of the upper outer wing (410) and lower outer wing (420), respectively, and hinge holes are formed in the spacer (300) to which the hinge projections (412, 422) are respectively connected. Accordingly, the upper outer wing (410) and the lower outer wing (420) are structured to rotate up and down together with respect to the spacer (300) by the connection of the hinge projections (412, 422) and the hinge holes.

[0051] The upper outer wing (410) and the lower outer wing (420) are connected to the knob pin (700) through the link mechanism (800), so that when the knob pin (700) rotates, the upper outer wing (410) and the lower outer wing (420) rotate together.

[0052] The support wing (500) includes an upper support wing (510) that rotates up and down relative to the spacer (300) as hinge projections (511) formed on the front left and right sides are coupled to hinge holes formed in the spacer (300) and a lower support wing (520) that rotates up and down relative to the spacer (300) as hinge projections (521) formed on the front left and right sides are coupled to hinge holes formed in the spacer (300) and are rotatably connected to the front end of the lower outer wing (420).

[0053] An inner wing (200) is positioned at the foremost position inside the duct (100), and an upper support wing (510) and a lower support wing (520) are positioned vertically symmetrically at the rear end of the inner wing (200), the rear end of the upper support wing (510) is connected to the upper outer wing (410), the rear end of the lower support wing (520) is connected to the lower outer wing (420), and the upper outer wing (410) and the lower outer wing (420) are positioned vertically symmetrically.

[0054] Accordingly, air passing through the inner wing (200) via the duct (100) is discharged into the interior through the front flow path (910) between the upper support wing (510) and the lower support wing (520) and the rear flow path (920) between the upper outer wing (410) and the lower outer wing (420).

[0055] The knob (600) includes a connecting part (610) that is coupled to the vertical rod (220) of the inner wing (200), and the connecting part (610) moves up and down along the vertical rod (220) when the knob (600) is rotated in the up and down direction, and moves the vertical rod (220) left and right when the knob (600) is operated in the left and right direction, thereby rotating the inner wing (200) left and right.

[0056] When the user moves the knob (600) left and right, the connecting part (610) moves the vertical rod (220) left and right, causing the inner wing (200) to rotate left and right relative to the duct (100) through the linkage (210), and at this time, the outer wing (400) and the support wing (500) maintain their positions without rotating up and down.

[0057] Then, when the user rotates the knob (600) by operating it up and down, the operating force of the knob (600) is transmitted to the outer wing (400) through the link mechanism (800), and the outer wing (400) and the support wing (500) rotate up and down together. At this time, the connecting part (610) of the knob (600) moves up and down along the vertical rod (220), and as a result, the inner wing (200) maintains its position without rotating left and right.

[0058] An embodiment according to the present invention is configured such that only a rear portion of the knob (600) protrudes outward (rear, indoor direction) of the duct (100) and is exposed to the interior, thereby helping to create a hidden effect and improve the aesthetic appearance.

[0059] The knob (600) according to the present invention includes an inner knob (620) that is integrally coupled with a knob pin (700) and rotates together with it, and an outer knob (630) that surrounds the inner knob (600), through which the knob pin (700) passes, and which is operated by a user.

[0060] The inner knob (620) and the knob pin (700) are joined together by a steel clip member (640) to form an integral unit.

[0061] When the outer knob (630) rotates up and down by user operation, the inner knob (620) and the knob pin (700) also rotate together, and when the outer knob (630) moves left and right by user operation, the inner knob (620) and the knob pin (700) are fixed in position, so that only the outer knob (630) moves left and right.

[0062] According to the present invention, the inner knob (620) and the outer knob (630) are provided with a spring (650) and a rubber (660) for managing the gap between the inner knob (620) and the outer knob (630) and for managing the operating force of the knob (600).

[0063] And, the knob pin (700) is wrapped by a decorative cover (710) and a back cover (720), and the decorative cover (710) and the back cover (720) are joined together.

[0064] The decorative cover (710) and the back cover (720) are formed to extend along the longitudinal direction of the knob pin (700), so that they form a structure that wraps around most of the knob pin (700) over its entire length, except for parts of both ends of the knob pin (700).

[0065] The knob pin (700), the decorative cover (710), and the back cover (720) all penetrate the knob (600) in the left-right direction and are located between the upper outer wing (410) and the lower outer wing (410).

[0066] In particular, the decorative cover (710) is installed so that both left and right ends are fixed to the duct (100) at an intermediate position in the vertical direction of the duct (100) and exposed to the interior, thereby enhancing the image of luxury, and furthermore, by covering the internal structure of the duct (100) through the decorative cover (710), it is possible to enhance the aesthetic appearance.

[0067] The outer knob (630) is provided with a rubber (670) to contact the decorative cover (710) for managing the gap between the outer knob (630) and the decorative cover (710) and for managing the operating force of the knob (600).

[0068] A link mechanism (800) that serves to rotate the outer wing (400) and the support wing (500) in the up and down direction when the knob (600) is operated in the up and down direction includes a first link (810) coupled to one end of the knob pin (700), and a second link (820) coupled to the first link (810) and having both ends coupled to the upper outer wing (410) and the lower outer wing (420).

[0069] When the knob pin (700) rotates by operating the knob (600) in the up and down direction, the first link (810) rotates, and when the first link (810) rotates, the second link (820) moves upward or downward along the rotation direction of the first link (810), thereby rotating the upper outer wing (410) and the lower outer wing (420) together, and at this time, the upper support wing (510) and the lower support wing (520) also rotate together, so that the direction of the air discharged into the room can be adjusted.

[0070] The first link (810) and the second link (820) according to the present invention are structured to connect one end of the knob pin (700) that penetrates the spacer (300) on the outside of the spacer (300), the guide projection (411) of the upper outer wing (410), and the guide projection (421) of the lower outer wing (420).

[0071] Accordingly, the spacer (300) has a structure in which a first guide hole (310) and a second guide hole (320) are formed vertically spaced apart to guide the movement of the upper outer wing (410) and the lower outer wing (420) when the second link (820) moves up and down in accordance with the rotation of the first link (810).

[0072] On the rear side of the duct (100) facing the interior, an upper garnish (930) and a lower garnish (940) are fixedly connected to the upper and lower sides based on the knob (600) to improve the appearance.

[0073] As shown in FIG. 3, when the knob (600) is positioned horizontally along the front and rear directions, the upper outer wing (410) and upper support wing (510) located above the knob (600) are characterized by being configured vertically symmetrically with the lower outer wing (420) and lower support wing (520) located below the knob (600). As a result, the airflow directionality of the air discharged into the interior through the front airway (910) and rear airway (920) after passing through the inner wing (200) can be improved.

[0074] As shown in Fig. 3, when the knob (600) is positioned horizontally along the front and rear directions, the air passing through the rear passage (920) is discharged toward the front of the passenger located inside the vehicle.

[0075] In addition, as shown in FIG. 3, when the knob (600) is positioned horizontally along the front and rear directions, the upper support wing (510) and the lower support wing (520) are configured such that their cross-sectional area gradually decreases from the front end to the rear end. Through this, the front flow path (910) between the upper support wing (510) and the lower support wing (520) functions as a nozzle, thereby having the advantage of increasing the air discharge speed toward the interior.

[0076] As the knob (600) is moved upward in the state of Fig. 3, the upper outer wing (410) and the lower outer wing (420) rotate upward as shown in Fig. 8, and the air passing through the front passage (910) is discharged upward through the rear passage (920). (Arrow M1)

[0077] And, as the knob (600) is moved downward in the state of FIG. 3, the upper outer wing (410) and the lower outer wing (420) rotate downward as in FIG. 9, and the air passing through the front passage (910) is discharged downward through the rear passage (920). (Arrow M2)

[0078] An embodiment according to the present invention is characterized in that the cross-sectional area (A1) of the rear passage (920) is always maintained at a constant size regardless of the vertical rotation of the upper outer wing (410) and the lower outer wing (420), and thereby, the air volume of air discharged into the room can always be maintained at a constant size, which has the advantage of improving the performance of the air vent.

[0079] That is, the cross-sectional area (A1) of the rear end of the rear air passage (920) through which air is discharged into the room is characterized by always maintaining a constant size regardless of the vertical rotation of the outer wing (400).

[0080] In addition, in an embodiment according to the present invention, when the upper outer wing (410) and the lower outer wing (420) rotate in the up and down direction, the upper support wing (510) and the lower support wing (520) have individually variable lengths.

[0081] That is, as shown in FIG. 8, when the upper outer wing (410) and the lower outer wing (420) rotate upward, the upper support wing (510) is varied so that its length increases, and conversely, as shown in FIG. 9, when the upper outer wing (410) and the lower outer wing (420) rotate downward, the lower support wing (520) is varied so that its length increases.

[0082] In order to allow the lengths of the upper support wing (510) and the lower support wing (520) to be variable, the upper support wing (510) and the lower support wing (520) are each characterized by a combined structure of a cylinder (512, 522) and a cylinder rod (513, 523) that moves along the cylinder (512, 522).

[0083] As described above, the slim air vent for a vehicle according to the present invention is configured such that the inner wing (200), the outer wing (400), and the support wing (500) are all positioned to be inserted inside the duct (100), while satisfying the performance standards for air vents regarding airflow direction, airflow volume, airflow directionality, noise, and airtightness. This allows the vertical height of the air vent to be significantly reduced, thereby enabling the configuration of a compact and slim air vent, the realization of a smart image and a premium image, and particularly has the advantage of being applicable to autonomous vehicles that have a smart image.

[0084] In addition, the slim air vent according to the present invention has the advantage of enabling a hidden effect and improving the aesthetic appearance as the inner wing (200), outer wing (400), and support wing (500) are all located inside the duct (100).

[0085] In addition, the slim air vent according to the present invention is characterized in that the cross-sectional area of ​​the rear passage (920) is always maintained at a constant size regardless of the vertical rotation of the upper outer wing (410) and the lower outer wing (420), and thereby, the air volume of air discharged into the room can always be maintained at a constant size, which has the advantage of improving the performance of the air vent.
