The present invention relates to a slim-type air vent of a vehicle. More specifically, the present invention relates to a slim-type air vent of a vehicle that can easily change a flow channel of air, which is discharged toward an exit through an outflow part of a duct, by means of each rotation relative to a hinge, according to a rotation state of a knob.
In general, due to the increase in size of a cluster and AVN (Audio, Video, Navigation) devices mounted inside automobiles, the location of installation of the air vent that discharges air according to the operation of the air conditioner and heater is moved to the lower area of the center fascia panel. In particular, there is a trend that the design of the appearance of the air vent is getting slim.
Generally, the air vent includes a center air vent mounted on a center fascia panel between the driver's seat and the front passenger's seat, and side vents mounted on a crash pad in front of the driver's seat and front passenger's seat, etc.

As shown in
In addition, a damper adjustment knob 14 is mounted rotatably at a position right next to the exit of the duct 10.
These conventional air vents adopt at least 6 horizontal and vertical wings, respectively, and thus have a wider structure. As such, there may be no problem with them in that the flow of air can be adjusted toward the body of a passenger (bottom: belly button, top: face), but because they are big in size, they have many problems, such as a package problem with surrounding parts and design restrictions.
Moreover, since the conventional air vent as above has a structure in which a plurality of horizontal and vertical wings are inevitably exposed, it occupies a large mounting space in the center fascia panel or crash pad, thereby eventually limiting the degree of design freedom on the cluster, AVNs placed around air vents, etc.
Accordingly, in order to improve the degree of design freedom on the cluster, AVN devices, etc., a slim type air vent in which only a single horizontal wing is exposed to the outside is adopted.
The slim air vent adopts a slim duct that is wider but shorter than the conventional air vent, so it does not occupy a large installation area, and accordingly, it can provide the advantage of improving the degree of design freedom on surrounding parts (such as the cluster, AVN devices, etc.), but since it is mounted at the exit of the slim duct and only a single horizontal wing is exposed to the outside, it is not possible to easily adjust the flow direction of the air discharged into the vehicle up and down, and not only that, it reduces the aesthetics of the interior of the vehicle, thereby reducing the vehicle's marketability.
The present invention was devised to solve such conventional problems as above, and the present invention is designed to provide a slim-type air vent of a vehicle to facilitate an easy assembly of a vane device in a duct, thereby easily changing a flow channel of air that is discharged toward an exit through an outflow part of a duct by means of each rotation relative to a hinge, according to a rotation state of a knob, while easily changing a flow channel of air that is introduced into an inflow part of the duct by means of the rotation of the vane device relative to a hinge according to the rotation state of the knob.
To achieve the objects above, the present invention comprises: a duct 200 having an inflow part 210 through which air is introduced and an outflow part 220 enlarged compared with the inflow part 210 and formed to communicate therewith: a vane device 100 for controlling the direction and the volume of the air discharged through an exit 221 formed in the outflow part 220 of the duct 200; and a knob 110 for providing a driving force such that the vane device 100 rotates about a hinge H.
Meanwhile, we would like to make it clear that the vane device 100 is composed of: a front vane link 120 in which the middle part of the connecting part 111 of the knob 110 is rotatably coupled around a hinge H: a rear vane link 130 in which the end of the connecting part 111 where the middle part is rotatably coupled to the front vane link 120 around a hinge H is rotatably connected to the middle part around a hinge H: an upper front vane 140 and a lower front vane 150 in which one end is rotatably coupled to the upper end and lower end of the rear vane link 130 around a hinge H, and the upper end and the lower end of the front vane link 120 are rotatably connected around a hinge H in a middle part: an upper rear vane 160 and a lower rear vane 170 in which one end is rotatably coupled to the other end of the lower front vane 150 and the upper front vane 140 around a hinge H; and a spacer 180 in which the other front and rear ends of the lower rear vane 170 and the upper rear vane 160 are rotatably coupled to the other part around a hinge H, and one front and rear ends of the upper front vane 140 and the lower front vane 150 are rotatably coupled to one part around a hinge H.
Further, a bezel 300 is fixedly installed at the exit 221 of the duct 200.
Meanwhile, we would like to make it clear that several vertical wings 190 connected by a vane link 400 are installed between the upper rear vane 160 and the lower rear vane 170, wherein a coupling hole 191 where a coupling protrusion 121 extending from the front vane link 120 is fit coupled is formed to pass through in any one of the vertical wings 190.
Meanwhile, we would like to make it clear that the upper and lower ends of the vertical wing 190 are rotatably coupled to a front upper spacer 500 and a front lower spacer 600 around a hinge shaft 192, wherein the front upper spacer 500 and the front lower spacer 600 are fixedly coupled to the lower rear vane 170 and the upper rear vane 160, respectively.
Further, we would like to make it clear that a guide hole 181 is formed to pass through in the other upper and lower parts of the spacer 180, such that a hinge H formed on the other front and rear ends of the lower rear vane 170 and the upper rear vane 160 is guided so as to rotate while moving.
According to the present invention, a bezel is combined toward the exit of a duct in a state where a vane device has been inserted into the duct, wherein the vane device can easily change a flow channel of air which is discharged toward an exit of a duct by means of the respective rotations of an upper front vane and an upper rear vane, and a lower front vane and a lower rear vane relative to a hinge according to a rotation state of a knob; thanks to this, a person in a vehicle can easily control the flow of air upwards or downwards that enters the vehicle through the duct by controlling the knob, and not only that, it can express the simple aesthetics of a slim air vent in appearance.
Hereinafter, the technical features of the present invention will be described in detail with reference to the accompanying drawings.
