Description

Air vent for vehicle {AIR VENT FOR VEHICLE}

The present invention relates to an air vent for a vehicle, and more particularly, to an air vent for a vehicle capable of providing a stopper structure for left and right rotation and vertical rotation and at the same time preventing the stopper structure from leaving a duct.

In general, automobiles are equipped with an air conditioning system that adjusts the indoor temperature according to the season, and the cold air and warmth generated from the air conditioning system are discharged into the interior of the vehicle through an air outlet installed in the instrument panel.

The air outlet is equipped with an air vent for controlling the wind direction and volume of the warm or cold air generated from the air conditioning system. That is, the warm or cold air generated from the air conditioning system passes through the duct and is discharged into the interior of the vehicle through the air vent. At this time, the wind direction of the discharged air is controlled by manipulating the knob provided in the air vent.

In the case of the conventional nozzle type circular air vent, the rotation radius of the nozzle assembly including the damper is formed large. Therefore, when the wind direction angle is set within 30°, which is the general wind direction control angle of the air vent, the air vent stopper for wind direction control leaves the duct, so the nozzle rotation cannot be stopped.

In order to solve this problem, it is necessary to reduce the diameter of the air vent outlet or reduce the wind direction control angle. When the outlet diameter is reduced, there is a problem of insufficient air discharge. When the wind direction control angle is reduced, the wind is sent at the desired target angle. An impossible problem arises. In addition, when the stopper is not separately included in the nozzle-type circular air vent, the nozzle rotates freely in the duct without a limiting angle, so that an internal structure such as a damper inside the nozzle is exposed to the exterior, and there is a problem in that it cannot provide a beautiful appearance. Therefore, there is a need to improve it.

Background art of the present invention is disclosed in Korean Patent Application Laid-Open No. 2010-0058374 (published on June 3, 2010, title of the invention: Air Vent).

As described above, according to the present invention, when the nozzle unit 20 is rotated in the vertical direction, the variable frame unit 70 does not move and the first rotation control unit 80 controls the vertical rotation angle of the nozzle unit 20 . Since it functions as a stopper, it is possible to prevent a phenomenon in which the variable frame part 70 protrudes to the outside of the duct part 10 to provide a beautiful appearance. In addition, when the nozzle unit 20 is rotated in the left and right direction, the variable frame unit 70 is rotated together with the nozzle unit 20 , and the variable frame unit 70 and the nozzle unit ( Since the rotation of 20) is made within a set angle, the range of rotation in the left and right directions of the nozzle unit 20 can be easily adjusted. In addition, the directional protrusion 92 is caught in the constraining groove 96 and the protrusion 102 is caught in the guide groove 104 by restricting the flow in the forward and backward directions of the nozzle unit 20 to prevent noise generation.
