Description

[0001] The present invention relates to a grille system for an air duct of a vehicle,

The present invention relates to a grill system for an air duct of a vehicle, and more particularly, to open the front part of the grill assembly when the air conditioning is carried out in the vehicle, and close the front part of the grill assembly when the air conditioning is not carried out, as well as whether to perform the air conditioning. Regardless of whether it is open or closed, the driver can manually adjust the opening or closing of the front of the grill assembly to prevent foreign matters such as dust from entering the air duct or the accumulation of dust on the grill. The front panel of the grill assembly is completely blocked by the door, and thus the grill system for the air duct of the vehicle has a structure that facilitates the interior cleaning of the vehicle, etc., so that the sanitary state of the vehicle can be kept clean at all times.

Generally, a conventional air duct grill for a vehicle includes a grill assembly installed at an inlet of an air duct to adjust a wind direction in a longitudinal direction or a transverse direction, and the grill assembly is manually operated by the user, Or the wind direction is fixed.

However, since the air duct of a vehicle equipped with the grill for the conventional air duct is always open, the foreign matter such as dust passes through the grill and enters and accumulates in the air duct. This breeding, of course, has a problem in that it is very difficult to clean the dust and the like accumulated on the grill assembly, which adversely affects the hygiene in the car.

The present invention has been made in view of the above-described conventional problems, the object of which is to open the front part of the grill assembly when the air conditioning is carried out in the car, as well as closing the front part of the grill assembly when air conditioning is not carried out By allowing the driver to manually adjust the opening or closing of the grill assembly at any time, whether it is implemented or not, it prevents foreign matter such as dust from entering the air duct or builds up dust on the grill and cleans the dashboard. The front part of the grill assembly is completely blocked by the opening and closing door, thereby providing a grill system for the air duct of the vehicle that can easily clean the interior of the vehicle and keep the sanitary state of the vehicle clean at all times.

An object of the present invention is a grill system for an air duct of the vehicle provided with a grill assembly and an air duct blowing fan installed in the air duct inlet formed on the dashboard of the vehicle to adjust the wind direction in the longitudinal or transverse direction, The grill system includes an opening / closing door which is assembled to an assembly groove concavely formed along an inner surface of the dashboard of the front side of the grill assembly and is slidably mounted along the assembly groove to open and close the front of the grill assembly; Driving means for driving the opening / closing door; A power transmission unit connecting the opening / closing door and the driving means and transmitting the driving force of the driving means to the opening / closing door; It is achieved by the grill system for the air duct of the vehicle, characterized in that it is electrically connected to the driving means and the air duct blowing fan, respectively, and the control unit for forward and reverse operation of the driving means by a predetermined potential in accordance with the ON / OFF of the blowing fan. It can be.

The grill system for the air duct of the vehicle according to the present invention is difficult to clean by completely blocking the front part of the grill assembly by the opening and closing door when the air conditioning for the vehicle interior is not carried out to keep the dashboard and the grill assembly front part flat. By preventing the accumulation of foreign substances such as dust on the inside of the air duct or the grill assembly, and at the same time to facilitate the cleaning of the dashboard has the effect of maintaining the hygiene state in the car always clean.
