However, the air intake shield is structured such that the outside air inflow portion faces the road surface so as to block the inflow of moisture and snow that can enter from the outside, and the downward opening structure of the outside air inflow portion causes hot air heated in the engine room to flow into the engine intake mechanism There is an inherent structural vulnerability.

An example of hot air heated in the engine room is a stopping state caused by signal waiting or a vehicle deceleration state in which the running wind inflow is reduced. Generally, the hot air is in a state of low air density, and the supply of the engine of such low density air causes knocking, which is inevitably accompanied by degradation of engine performance.

Accordingly, the present invention takes the above-mentioned points into consideration and increases the wind pressure of the running wind linked to the running speed of the vehicle, thereby guiding the inflow of the outside air at the time of high-speed traveling downward to block the inflow of moisture and snow that can come from the outside, The object of the present invention is to provide a wind-fed interlocked outdoor air introducing device that prevents high-temperature outside air warmed by the engine from being directly introduced into the engine intake system when the low-speed traveling without wind pressure or idle, have.

In order to achieve the above object, an air intake hose for supplying air to an engine combustion chamber of the present invention is connected to an FEM (Front End Module), and a wind pressure Wherein the air flow interlocking air shield includes an outer air inflow duct in which a front air flow path leading to the air intake hose is formed and a front air inflow duct in which the front air flow path is narrowed by increasing the wind pressure of the running air introduced into the outside air inflow duct And a duct valve through which the bottom air flow passage leading to the air intake hose is formed through the bottom surface of the outside air inflow duct.

The outside air inflow duct comprises a main outside air introduction port forming the front airflow passage and a sub outside air introduction port forming the bottom air flow passage; The sub-ambient air introduction port is provided with the duct valve.

The duct valve includes an air guard for receiving the air flow introduced into the front air flow passage, a weight balancer for lowering the air guard to the bottom surface of the front air flow passage to block the bottom air flow passage, And an air guard stopper which tilts the front portion of the air guard so as to receive the wind pressure of the running wind directly.

The center of gravity of the air guard is fixed to the bottom air flow passage, and the weight balancer is provided at the bottom of the air guard at the position of the center of rotation.

The weight balancer further includes a weight, and the weight strengthens the rotational force by the weight of the air guard.

The air guard stopper is installed on the bottom surface of the front air flow passage.

The shaft of the motor and the shaft of the actuator are connected to the rotation center of the air guard, and the air guard is rotated by the motor and the actuator.

The air-pressure interlocking air shield further includes an air shield lower cover for covering a front portion of the duct valve.

In the present invention, the inflow direction of the outside air introduced into the engine intake mechanism is guided downward in the middle speed range, thereby blocking the inflow of moisture and snow that can enter from the outside, while the inflow of outside air at the time of low- The high temperature external air warmed by the engine is prevented from flowing directly into the engine intake machine when the outside air flows downward.

Further, according to the present invention, the switching of the outside air inflow direction interlocked with the vehicle speed uses the wind pressure of the running wind, so that it is possible to manufacture the windmill without a configuration connected to the air intake hose or FEM (Front End Module).

In addition, the present invention can replace the existing air intake shield directed to the road surface by replacing the outside air inlet direction interlocked with the vehicle speed as an independent separate material. Especially, when replacing the existing air intake shield, (Front End Module).

In addition, the present invention relates to an air conditioner for an internal combustion engine, which is capable of guiding the inflow direction of the outside air downward regardless of the vehicle speed by switching the inflow direction of the outside air introduced into the engine intake machine to be connected to the motor power, It has the effect of completely blocking the inflow of moisture and snow that can come from the outside in the coming weather conditions.

2 is a view showing an example in which the wind-driven interlocking type outdoor air-introducing device of the present invention is combined with a power source, FIG. 3 is a schematic view of the wind- Fig. 5 is a state of operation of the wind-driven interlocking type outside air introduction apparatus according to the present invention at the time of middle-speed running. Fig. Is an operating state at the time of stop of the wind-driven interlocking type outside air introduction apparatus according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The present invention is not limited to these embodiments.

Fig. 1 shows the construction of a wind-driven interlocked outdoor unit according to the present embodiment.

As shown in the figure, the wind-pressure interlocking type outdoor air introducing device includes an air intake hose 5 fixed to the FEM suction hole 3-1 of the FEM (Front End Module) 3 positioned on the front side of the radiator 1, And a wind pressure interlocking air shield 10 which is positioned on the front surface of the FEM suction hole 3-1 and guides ambient air to the air intake hose 5. [

The air-pressure interlocking air shield 10 includes an air inlet duct 20 through which air is passed and is sent to the air intake hose 5 and a duct valve 30 And an air shield lower cover 40 for covering the front portion of the duct valve 30. [

A main outside air inlet 20-1 for introducing outside air from the front side of the outside air inflow duct 20 so that the air current is sent to the air intake hose 5 without changing direction, A sub outside inlet 20-2 for introducing outside air from the bottom of the outside air inlet duct 20 so as to be sent to the air intake hose 5 after being redirected is formed.

A duct valve 30 is provided in the sub outside air introduction port 20-2 and the sub outside air introduction port 20-2 is blocked by a duct valve 30 which is not subjected to the wind pressure of the running wind. Therefore, the hot air heated by the engine at the time of stopping the vehicle or at the time of engine idle can not be introduced into the sub outside-air introduction port 20-2.

The duct valve 30 includes an air guard 31 that is tilted backward to receive air flow, a weight balancer 33 that reduces the air guard 31 forward, And an air guard stopper 35 for raising the air guard 31 so that wind pressure due to the running wind acts even in a descending state.

The air guard 31 has a flat plate shape and has a width such that the width does not contact the main outside air inlet 20-1 and the outside air inlet 20-2.

The air guard 31 is further provided with an air guard rotating shaft 32 serving as a rotating center when the air baler 31 is turned backward due to forward tilting or wind pressure of the running wind, 32 are formed at positions shifted to one side from an intermediate position of the entire length of the air guard 31.

The air guard rotary shaft 32 may be rotatably connected to the sub air outlet inlet 20-2 of the air inlet duct 20 or may be directly connected to the air inlet duct 20 in a rotatable manner.

Therefore, the air guard rotary shaft 32 may be a protrusion protruding from both left and right sides of the air guard 31, or may be a shaft passing through the width of the air guard 31. [

The weight balancer 33 is integrally formed with the air guard 31 and is provided at a position where the air guard rotary shaft 32 is formed. The weight balancer 33 is weighted on the lower end portion and further includes a weight 33-1 which is a heavy object for weight concentration.

The air guard stopper 35 is provided on the bottom surface of the main outside air inlet 20-1 of the air guard 31 as a block having a predetermined height.

2 shows an example in which the wind-driven interlocked outdoor air introducing device of the present invention is combined with a power source.

As shown in the figure, the air-pressure interlocking air shield 10-1 has only a difference in that the duct valve 30 is rotated by using a separate power source without being rotated by the weight of the weight balancer 33 and the wind pressure of the running wind .

To this end, the power source may be a motor 50-1 or an actuator 50-2.

Therefore, when the motor 50-1 or the actuator 50-2 is used as a power source, the wind pressure interlocking air shield 10-1 is provided with the main outside air inlet 20-1 and the outside air inlet 20-2, Can be clarified.

For example, when the weather is clear and there is no rain or snow inflow (which can be judged by a weather sensor or an intake air temperature sensor), the main outside air inlet 20-1 is opened to allow the running wind pressure to enter When the weather deteriorates, the main outdoor air intake opening 20-1 is closed and the auxiliary outdoor air intake opening 20-2 is opened to prevent snow or rainwater from entering during traveling.

3 shows an initial operating state of the wind-driven interlocked outdoor air introducing apparatus 10 according to the present embodiment.

When the duct pressure of the running wind is not large and the duct valve 30 receives the wind pressure Pa of the running wind due to the initial stage of the running, the duct pressure valve 30 is connected to the weight balancer 33, He will not be able to overcome his suffering.

Therefore, the duct valve 30 is turned to the maximum forward position by the weight balancer 33, so that the main outside air inlet 20-1 is opened to the maximum while the sub outside air inlet 20-2 is completely blocked .

Therefore, air is forced to be sent to the air intake hose 5 depending on the amount of the running wind that has entered the main outside air inlet 20-1. However, in this case, since the vehicle is in the initial state of running, the wind pressure and the speed of the running wind are weak, so that snow or rainwater can not flow together with the running wind.

However, if the wind pressure and the speed of the running wind gradually increase after passing the initial driving state, the wind pressure of the running wind is also changed to Pa-1 which is relatively large in Pa, and the duct valve 30 is relatively increased in wind pressure (Pa-1) The air guard 31 overcomes the weight of the weight balancer 33 and starts to be tilted backward.

Meanwhile, FIG. 4 shows a state in which the duct valve 30 receives the relatively increased wind pressure Pb as the vehicle enters the low-speed running at the beginning of the running.

As shown in the figure, the duct valve 30 receives the wind pressure Pb which is larger than the wind pressure Pa, Pa-1 so that the air guard 31 overcomes the weight of the weight balancer 33 and is turned backward, The air volume of the running wind introduced into the outside air inlet 20-1 is reduced while the air flow amount of the running air introduced into the outside air inlet 20-2 starts to increase.

Therefore, the air to be sent to the air intake hose 5 is combined with the air introduced into the sub outside air introduction port 20-2 through the air passing through the main outside air introduction port 20-1, Can be supplied sufficiently.

On the other hand, FIG. 5 shows a state in which the duct valve 30 receives the relatively increased wind pressure Pb as the vehicle enters the high speed running at low speed.

As shown in the drawing, the duct valve 30 receives the wind pressure Pb that is larger than the wind pressure Pa, Pa-1, so that the air guard 31 overcomes the weight of the weight balancer 33, , The main outside air introduction port 20-1 is completely blocked by the air guard 31 while the sub outside air introduction port 20-2 is completely opened.

Therefore, the air is totally introduced into the air intake hose 5 through the sub outside air introduction port 20-2, so that the air flow rate required by the engine is sufficiently supplied, and even if snow or rainwater flows along with the running air, It can be blocked by the guard 31.

On the other hand, Fig. 6 shows the operating state of the wind-driven interlocked outdoor air introducing apparatus 10 when the vehicle stops or when the vehicle idles.

As shown in the figure, since the running wind is not formed due to the stop of the vehicle, the duct valve 30 is forced to be placed under the action of the weight balancer 33 completely.

Therefore, the air guard 31 of the duct valve 30 is completely turned forward by the weight received from the weight balancer 33, so that the main outside air inlet 20-1 is opened to the maximum, The sphere 20-2 is completely cut off.

Therefore, air is forced to be sent to the air intake hose 5 depending on the amount of the running wind that has entered the main outside air inlet 20-1. However, in this case, since the vehicle is in a stopped state, there is no inflow of snow or rainwater due to running wind.

Since the sub outside air introduction port 20-2 is completely shut off by the air guard 31, the hot air heated by the engine is not sent to the air intake hose 5 through the sub outside air introduction port 20-2 do.

Therefore, since the air density is low, supply of the hot air which can cause knocking is prevented, so that the engine performance is not deteriorated even when the vehicle stops or the engine idles.

As described above, the air-entrained outdoor air introducing apparatus according to the present embodiment is provided with the outside air inflow duct 20 having the front air flow passage leading to the air intake hose 5, the running air introduced into the outside air inflow duct 20, A duct valve 30 for narrowing the front airflow passage with increasing wind pressure and forming a bottom airflow passage leading to the air intake hose 5 through the bottom surface of the outside air inflow duct 20, By increasing the wind pressure of the driving wind linked to the speed, the inflow of outside air is guided downward at high speed driving to block the inflow of moisture and snow that can come from the outside, and in the case of idling at low speed without running wind, It is possible to prevent the supply of high-temperature air that can cause knocking due to low air density, It can jidoel.
