Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a bulge hatch that is fixed to the upper surface of the hood of an automobile.

<Prior Art> In a turbocharged engine, a bulge hatch 3 with an air intake port 2 is provided on a hood 1 so as to take in outside air into the engine room for cooling the intercooler, as shown in FIG. There is.

In addition, in order to prevent insects from colliding with the windshield while driving at high speeds and to prevent the wipers from lifting up during rainy weather, a deflector 4 is fixedly installed on the hood 1 to prevent the airflow from flying over the roof. The flow is rectified on the top surface.

<Problems to be solved by the invention> As mentioned above, in the past, the bulge hatch 3 had only the function of taking in outside air, and the deflector 4 had only the function of rectifying the airflow, and each was provided separately. There is no such thing that has both functions at the same time.

<Means for solving the problem> The present invention has a bulge hatch protruding from the top surface of the hood to take in outside air, and deflectors are installed on both sides of the bulge hatch body so that they can be rotated in a direction perpendicular to the direction of travel of the vehicle. The deflector is provided with an air intake, and this air intake is connected to both sides of the bulge hatch body using an expandable duct.

<Function> With the above configuration, the deflector is opened as necessary to rectify the airflow, and at the same time, outside air is taken into the bulge hatch through the elastic duct from the air intake provided in the deflector, and the amount of air intake is increase.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. In FIGS. 1 and 2, 1 is a hood, 3 is a bulge hatch protruding from the hood 1, and an air intake port 2 is provided in the front surface.

In the present invention, deflectors 5 are provided on both sides of the main body of the bulge hatch 3 so as to be rotatable in a direction perpendicular to the traveling direction of the vehicle.
An air intake 6 is provided in the bulge hatch 3, and the air intake 6 and both sides of the main body of the bulge hatch 3 are connected by an expandable duct 7 such as a bellows.

As shown in FIG. 3, for example, the turning device for the deflector 5 has a small motor 9 installed in the bulge hatch 3, and the forward and reverse rotation of the small motor 9 is controlled by a gear 10 to control the rotation axis of the deflector 5. 8
It is a structure that transmits information.

Since the present invention has the above-mentioned structure, during normal driving when the deflector 5 is not required, the deflector 5 is stored on both sides of the main body of the bulge hatch 3, and during high-speed driving, the deflector 5 is opened to straighten the airflow. , prevents insects from colliding with the windshield and prevents wipers from lifting up in the rain. At this time, air is taken in from the air intake port 6 of the deflector 5 and introduced into the bulge hatch 3 through the expandable and contractible duct 7. This merges with the air taken in by the bulge hatch 3 itself, increases the amount of air, and guides it into the engine room.

<Effects of the invention> As described above, according to the invention, since the deflector that can be opened and closed is provided on both sides of the bulge hatch body provided on the top surface of the hood, it is possible to prevent insects.
The deflector is opened only when it is necessary to rectify the airflow, such as to prevent the wiper from lifting up.The deflector is normally stored on both sides of the bulge hatch, so it has the same form as a normal bulge hatch, improving the design, and also allowing it to be used outside the hood. Maintenance such as car washing and waxing of the board becomes easier.

Furthermore, the deflector is provided with an air intake, and this is connected to the side of the bulge hatch body using an expandable duct, allowing air to be taken into the bulge hatch from the deflector as well, allowing for long periods of high rotation. By opening the deflector when the vehicle is running at high speed, the amount of air is increased, which has the advantage of increasing the cooling effect of internal components such as the intercooler.

Claims (1)

[Scope of utility model registration request] In the bulge hatch that protrudes from the top surface of the hood to take in outside air, deflectors are provided on both sides of the bulge hatch body so that they can be turned in a direction perpendicular to the direction of travel of the vehicle, and an air intake port is opened in this deflector. This bulge hatch is characterized by connecting this air intake and both sides of the bulge hatch body with an expandable duct.
