Description

Air shutter system of radiator grille for automobile

The present invention relates to a radiator grille air shutter system for automobiles, and more particularly, to improve the durability of the air shutter system, thereby minimizing inadvertent operation of the air shutter, so that external air is required to open the air shutter or to remove external air. The present invention relates to a radiator grille air shutter system for automobiles capable of improving fuel efficiency by preventing the engine from overheating and preventing unnecessary fuel loss by allowing the air shutter to operate smoothly when closing the air shutter.

In general, in the engine room of a vehicle, various kinds of radiators, intercoolers, evaporators, condensers, etc., for cooling each component in the vehicle, such as an engine, as well as an engine for driving the vehicle, or for controlling the air temperature in the vehicle interior, etc. Heat exchangers (hereinafter referred to as cooling modules) are installed.

In the cooling module, a heat exchange medium is generally distributed therein so that the heat exchange medium inside the cooling module and the air outside the cooling module exchange heat with each other, thereby cooling or radiating the cooling module.

Therefore, in order for the cooling module in the engine room to operate stably, the outside air must be smoothly supplied into the engine room.

This external air is introduced into the engine room through the vent holes of the bumper grill and the radiator grill to cool the cooling module.

However, when the outside air enters the engine room all four seasons, that is, when the outside air enters the engine room during the winter season, the engine heating time is increased by that much, which reduces the fuel economy and also the resistance of the air continuously flowing during driving. Because of this, the fuel economy will fall.

Therefore, as in 2000 Patent Application No. 65470, which was previously filed to solve this problem, a shutter is installed in the radiator to open the shutter only when external air is required, so that air can be introduced into the engine room. To close outside air from entering the engine compartment.

However, the conventional patented shutter structure is that a plurality of all gears are connected by a belt so that when one gear is rotated by the movable means, all the gears are rotated to open or close the shutter.

However, this structure not only does the shutter not operate smoothly even if one of the gears is broken or worn, or the belt is loose, but also the shutter does not operate when the belt suddenly breaks down due to long-term use. If the shutter does not open, the outside air does not flow smoothly into the engine room, so the cooling efficiency of the cooling module decreases and the engine is easily heated.

In addition, if the shutter is kept open, the outside air continues to flow into the engine room, so in winter, the engine heating time is increased by the initial engine start, which causes unnecessary fuel waste.

Therefore, the present invention is to solve such a conventional problem, the object of the present invention is to improve the durability of the air shutter by minimizing the air shutter is not operating properly suddenly, when the outside air is required smoothly into the engine room air It is to provide a radiator grille air shutter system for automobiles that can save fuel by preventing the engine from overheating by inflow, or blocking external air when it is not needed to reduce the heating time of the engine at initial start-up.

In order to achieve the object of the present invention, the present invention is a radiator grille air shutter system for automobiles installed between the radiator grill and the cooling module, it is installed continuously connected up and down as a plate having a certain length and width, connected to both rear top upper A plurality of air shutters formed with a connecting portion provided with protrusions, and rotating shafts are provided at both lower ends of the rear surface, respectively; At one side, the shaft hole into which the rotary shaft of the air shutter is fitted is formed at regular intervals above and below to maintain the installation state of the air shutters, and the other side includes a support attached to the radiator grill; A guide bar having a plurality of protrusions into which the connection protrusions of the connection parts are fitted to operate a plurality of air shutters connected in series; An actuator for opening and closing the air shutter by raising or lowering the guide bar according to the set temperature of the coolant detected by the temperature sensor; Characterized in that consisting of.

The present invention improves the durability of the air shutter to minimize the inability to operate the air shutter properly to open the air shutter or to close the open air shutter at any time to introduce outside air into the engine room. This allows the external air to flow into the engine room if necessary to prevent overheating of the engine, and cuts off the external air when it is not needed, thereby reducing engine heating time during initial start-up and preventing unnecessary waste of fuel, resulting in improved fuel economy. It has an effect.
