Mesh portions 250 may be formed on upper and lower sides of the blade 210. The mesh unit 250 disperses hot or cold air supplied from the duct unit 100 to the user. That is, the air discharged to the mesh unit 250 may be dispersed and discharged in a state in which the air velocity of air is reduced. As a result, the user may reduce the discomfort caused by cold or warmth.

On the other hand, the wind of 0.15m / s or less without the cold draft (ASH flow caused by the temperature difference due to cooling) standard is defined as still air. In one embodiment of the present invention it should be understood to include more than 0.15m / s or less.

3 is a cross-sectional perspective view of a vehicle air vent 1000 according to an embodiment of the present invention, Figure 4 is an opening and closing state of the first flow path (S1) and the second flow path (S2) according to an embodiment of the present invention. It is a figure which shows.

The vent part 200 may include a blade 210, a knob 220, a rotation shaft 230, an air guide 240, a mesh part 250, and a horizontal axis 260.

The blade 210 may be formed of a vertical blade 211 and a horizontal blade 212.

The vertical blades 211 may be formed in plural along the width direction of the vent part 200. The vertical blade 211 may be formed with a link member at each end to be integrally rotated. As the vertical blade 211 is rotated, the direction of the discharged air is adjusted left and right.

The horizontal blades 212 may be formed in plural along the height direction of the vent part 200. The horizontal blade 212 may be formed with a link member connected to each end to be integrally rotated. As the horizontal blade 212 is rotated, the direction of the discharged air may be adjusted up and down.

A knob 220 may be formed on any one of the horizontal blades 212. As the user manipulates the knob 220, the direction of the discharged air is adjusted. On the exposed surface of the knob 220, a groove or a non-slip member may be formed to grip the user.

The knob 220 may have a handle formed on one side and a universal joint 221 formed on the other side. The universal joint 221 is already known and detailed description thereof will be omitted.

The rotary shaft 230 may have one side coupled to the universal joint 221 and the other side of the rotary shaft gear 231.

When the rotation shaft gear 231 is rotated, the horizontal shaft 260 meshed with the rotation shaft gear 231 may rotate.

The horizontal axis 260 is horizontally formed at the rear end of the vent part 200 and may be coupled to be rotatable. A cross section of the horizontal shaft 260 is formed in a circular shape, and a first horizontal shaft gear 261 and a second horizontal shaft gear 262 may be formed on a surface thereof.

When the user rotates the knob 220, the rotation shaft 230 may be rotated. As the rotating shaft 230 is rotated, the horizontal shaft 260 engaged with the rotating shaft 230 rotates, which may lead to the rotation of the air guide 240.

The air guide 240 may be formed in a square plate shape having a predetermined area so as to control the direction in which the air travels.

The air guide 240 may be formed of the first air guide 241 and the second air guide 242.

Hereinafter, the downstream side along the air discharge direction is defined as the front, and the upstream side is defined as the rear.

One side of the first air guide 241 is coupled to the rear upper side of the vent part 200 is formed to be rotatable at a predetermined angle. The other side of the first air guide 241 is in contact with the inside of the duct part 100, and is rotated to be in contact with the second air guide 242. The other side of the first air guide 241 may be formed to be bent upwards.

The other side of the second air guide 242 is in contact with the inside of the duct part 100, and when in contact with the first air guide 241. The other side of the second air guide 242 may be formed bent downward.

The bent surfaces of the first air guide 241 and the second air guide 242 are in contact with each other at the time of rotation, the flow direction of air can be changed.

Since the air guide 240 may be worn due to frequent rotation and friction, some or all of the air guide 240 may be made of a material resistant to wear, such as rubber and silicone.

On the other hand, the mesh portion 250 may be formed on the upper and lower sides of the horizontal blade (212). The mesh unit 250 may disperse air supplied through the duct unit 100 and discharge the air to the user. The air discharged through the mesh unit 250 may reduce the wind speed, thereby reducing the discomfort that the user feels due to cold or warm air.

An air vent for a vehicle according to an exemplary embodiment of the present invention may include a first flow path S1 and a second flow path S2.

The first flow path S1 may be formed as an inner surface of the vent part 200. Air discharged through the first flow path S1 is discharged at a general wind speed. The first flow path S1 provides rapid cooling to the user at the initial stage of air conditioning to make the user feel comfortable.

The blade 210 is provided in front of the first flow path S1 to adjust the direction of the discharged air.

That is, as shown in FIG. 4A, when the first flow path S1 is opened, the vehicle air vent 1000 is in a blowing mode, and thus, cool air may be supplied to a vehicle interior at a predetermined wind speed.

The second flow path S2 may be formed as an inner surface of the duct part 100 and an outer surface of the vent part 200.

In the drawing, although the second flow path S2 is illustrated as being formed above and below the first flow path S1, the second flow path S2 may be formed on the left and right sides of the first flow path S1. The position of the mesh unit 250 may be changed according to the position where the first flow path S1 is formed.

The mesh part 250 may be formed in front of the second flow path S2. The mesh unit 250 may reduce the wind speed by dispersing the discharged air. The second flow path S2 may discharge the air having the reduced wind speed to the user in the middle or late stage of air conditioning, thereby reducing discomfort that the user feels through cold air.

That is, when the second flow path S2 is opened, the user may use the windless mode.

In the early stage of air conditioning, the first passage S1 is opened to maintain cooling at a constant wind speed, and in the middle or late stage of air conditioning, the user opens the second passage S2 to achieve airless cooling at a reduced wind speed.

When the user rotates the knob 220, the rotary shaft 230 coupled to the knob 220 and the universal joint 221 is rotated. The rotary shaft gear 231 of the rotary shaft 230 is meshed with the first horizontal shaft gear 261, so that the horizontal shaft 260 may be rotated after the rotary shaft 230.

As the horizontal shaft 260 is rotated, the second horizontal shaft gear 262 is rotated, and the second guide gear 242a engaged with the horizontal shaft 260 is operated.

In FIG. 4, only the second guide gear 242a formed in the second air guide 242 is illustrated, but a first guide gear (not shown) may also be formed in the first air guide 241.

The second horizontal shaft gear 262 and the second guide gear 242a are engaged with each other, and eventually the second air guide 242 is rotated.

The first air guide 241 may also be rotated in a manner corresponding to the second air guide 242.

As the first air guide 241 and the second air guide 242 are rotated by the knob 220, the first flow path S1 and the second flow path S2 may be opened and closed.

In other words, when the first flow path S1 is opened as shown in FIG. 4 (a), the user feels the wind speed and can use a blowing mode that can provide a rapid cooling effect. As such, when the second flow path S2 is opened, the user may use a windless mode in which discomfort caused by cold is reduced.

Conventionally, the user has an unpleasant feeling that the cold air directly touches the skin as the air is cooled at a certain level of wind speed, but the air vent for the vehicle according to an embodiment of the present invention can be adjusted to a non-air mode, thereby stopping cooling due to the unpleasant feeling. Work can be reduced. Through this, it may be easy to maintain the inside of the vehicle at a constant temperature.
