Description

Technical Field

[0001] The present invention relates to a thin vent for an automobile, and more particularly to a thin vent for an automobile that rotates about a hinge according to the rotation state of a knob, thereby easily changing the flow path of air discharged toward an outlet through a discharge portion of a ventilation duct. Background Art

[0002] As instrument panels and AVN (Audio, Video, Navigation) devices commonly installed in cars have become larger, the installation location of air vents, which exhaust air after the air conditioner and heater are in operation, has gradually moved to the lower area of the center console. In particular, the design of air vents has gradually shown a slim design trend.

[0003] Generally speaking, the above-mentioned vents include: central vents, which are installed on the center console between the driver's seat and the opposite side of the passenger seat; and side vents, which are installed on the side trim panels opposite the driver's seat and the passenger seat.

[0004] In the attached figure Figure 1 The figure shows the appearance of a central vent among existing vents.

[0005] like Figure 1 As shown, multiple transverse blades 11 and longitudinal blades 12 are installed at the outlet of the ventilation duct 10 in a rotatable manner, and a wind direction adjustment knob 13 for adjusting the up and down angles of the transverse blades 11 and the left and right angles of the longitudinal blades 12 is installed on one of the multiple transverse blades 11.

[0006] Furthermore, a damper adjustment knob 14 capable of being rotated is installed next to the outlet of the ventilation duct 10 .

[0007] Such existing vents typically have at least six transverse blades and six longitudinal blades, creating a structure with very large vertical widths. This allows the direction of air discharged into the vehicle to be easily adjusted to the passenger's body side (lower end: navel; upper end: face). However, the large size of the vents makes it impossible to integrate them with surrounding components, resulting in many design restrictions.

[0008] In particular, the existing vents as described above can only form a structure in which multiple horizontal blades and vertical blades are exposed outward in appearance, and thus occupy a large installation space in the center console or trim panel, which becomes a reason for reducing the design freedom of instruments and AVN devices arranged around the vents.

[0009] Therefore, in order to improve the degree of freedom in designing the above-mentioned instrument panel, AVN device, etc., a thin vent is adopted in which only a single lateral blade is exposed to the outside.

[0010] Compared to existing vents, the above-mentioned thin vents utilize a thin duct with a greater left-to-right length and a lower vertical height, thereby offering the advantage of improved design freedom for surrounding components (such as instruments and AVN devices). However, since they are installed with a structure that exposes only a single transverse blade at the outlet of the thin vent duct, it becomes difficult to easily adjust the flow direction of the air discharged into the vehicle vertically. Furthermore, the aesthetic appearance of the vehicle interior is also reduced, thereby posing a problem such as a decrease in the commercial value of the vehicle.

[0036] Furthermore, the ventilation duct 200 is formed to penetrate the ventilation duct 200 in such a manner that the opening of the discharge portion 220 where the vane unit 100 is installed is larger than the opening of the inlet portion 210 where the air flows in.

[0037] On the other hand, a frame plate 300 is fixed to the outlet 221 formed in the discharge portion 220 of the ventilation duct 200 .

[0038] In addition, a plurality of longitudinal blades 190 connected by a blade connecting rod 400 are arranged between the above-mentioned upper rear blade 160 and the lower rear blade 170, and a connecting hole 191 is formed through one of the above-mentioned longitudinal blades 190 to enable the connecting protrusion 121 formed by extending the front blade connecting rod 120 to be buckled.
