Abstract

PURPOSE:To improve heat radiating effect and appearance by making an air scoop for engine room heat radiation, being arranged in a bonnet hood, rise and set to the bonnet hood, interlocking with operation and nonoperation of a supercharger. CONSTITUTION:For an air scoop 1, the rear end is pivoted on a bonnet hood 2 through a hinge 3, and also an opening 4 is formed at the front. And to a bracket 5 being fixed to the center of the inner face of the air scoop 1, one end of a link 6, whose middle part is pivoted on the bonnet hood 2 through a pin 8, is connected through a rod 7. Moreover, the other end of the link 6 is connected to the plunger 10 of a solenoid 9 which interlocks with a supercharger. Furthermore, a moderation spring 11 is interposed between one end of the link 6 and the bonnet hood 2. Hereby, the air scoop 1 is rocked upward only af the time of operation of the supercharger, and the outside air is introduced through the opening 4 so as to cool an intercooler 12, etc.

Description

[Detailed Description of the Invention] a. INDUSTRIAL APPLICATION FIELD OF THE INVENTION The present invention relates to an automobile hood structure in which an air scoop can be used only when driving at high speeds.

b. 2. Description of the Related Art Automobiles are known in which an air scoop for taking in air is provided in the bonnet hood in order to cool the engine compartment.

The air scoop is usually fixed to the bonnet hood, so when the vehicle is running, outside air is introduced into the engine compartment regardless of the speed.

However, when idling or driving at low speeds,
The hot air inside the engine compartment was flowing out through the air scoop and was introduced through the outside air intake port of the air conditioner, reducing the functionality of the air conditioner.

Therefore, an automobile hood structure (Utility Model No. 62-8452
6) is known.

C. Problem to be Solved by the Invention However, in this prior art, the hot air exhausted to the outside is reintroduced through the outside air suction port of the air conditioner, which has the disadvantage that the function of the air conditioner deteriorates. there were. Additionally, in the prior art, the wind direction guide plate protruded from the bonnet hood regardless of the speed, which was a design flaw. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a hood structure for an automobile that is provided with an air scoop that protrudes from the bonnet hood and introduces outside air only when the vehicle is running at high speed.

d. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has an automobile hood structure in which an air scoop for heat dissipation in the engine room is provided on the bonnet hood. This is due to the provision of an air scoop that is stored inside the Bonnesoto hood during operation.

e. At high speeds when the supercharger is activated, an air scoop protrudes from the bonnet hood. An air scoop is stored inside the bonnet hood during idling or low speed driving when the supercharger is not activated. f. EXAMPLE Hereinafter, an example of the present invention will be explained in detail with reference to the drawings. 1 to 3, reference numeral 1 denotes an air scoop provided on a bonnet hood 2 of an automobile, and the rear end of this air scoop is attached to the bonnet hood 2 via a hinge 3. As shown in Fig. 4, the air scoop 1 has an opening 4 formed in the front surface, and the opening 4 is exposed above the bonnet hood 2 to let in outside air. A bracket 5 is attached to the inner surface of the air scoop 1, and one end of the bracket 5 and an L-shaped link 6 are connected by a rod 7. The link 6 has an intermediate portion pivotally supported by the bonnet hood 2 through a pin 8, and the other end of the link 6 is pivotally supported by a plunger 10 of a solenoid 9. This solenoid 9 is energized and activated when a supercharger (not shown) is activated, and rotates the link 6. 11
is a moderation spring provided between the bonnet hood 2 and one end of the link 6. 12 is intertala. According to the above configuration, in an idling state or a low-speed running state in which the supercharger does not operate, the link 6 rotates under the action of the moderation spring 1l, and the air scoop 1 is housed in the bonnet hood 2. When the supercharger operates at high speed, the solenoid 9 is energized to operate the plunger 10 and rotate the link 6 against the biasing force of the moderation spring 11. As a result, the air scoop 1 is pushed up and protrudes from the upper surface of the bonnet hood 2. and,
Outside air is introduced into the bonnet hood 2 to cool the intertellar 12 and the like.

g. Effects of the Invention As described above, according to the automobile hood structure according to the present invention, the air scoop protrudes from the bonnet hood when the supercharger is in operation, and the air scoop is housed within the bonnet hood when the supercharger is not in operation. Therefore, hot air in the engine compartment is not introduced into the passenger compartment during low-speed driving. Additionally, the air scoop is stored inside the bonnet hood when the turbocharger is not in operation, improving the design.
