Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air intake device for a vehicle, which is installed in a hood of a vehicle and takes in air flowing along the upper surface of the hood.

[0002]

2. Description of the Related Art Conventionally, an opening is formed on the upper surface of a bonnet when the amount of air taken in from the front grill becomes insufficient because the front grill area becomes smaller as the vehicle height becomes lower. An air scoop that covers the opening and has a front opening is provided to take in air flowing along the upper surface of the hood into the engine room. For example, Shokai Sho 60-72323
What is described in the publication is that a ventilation port (opening) is opened in a bonnet that covers the upper part of the engine room where a forced fan for cooling the radiator is installed, and the ventilation port (opening) is opened in the bonnet. An air scoop that covers the front and opens forward is provided, and a baffle plate is erected between the air scoop opening and the front end of the ventilation port.

[0003]

However, in the above-mentioned conventional air intake device, the flow of the air flowing from the opening at the tip of the air scoop is not smooth, and the amount of air flowing into the engine room from the opening of the bonnet is insufficient. There was a problem of doing. For example, in order to reduce the vehicle height, the space on the engine is small, and the layout is such that the intercooler is installed between the engine and the battery so that the longitudinal direction of the intercooler matches the longitudinal direction of the intercooler. In a vertically installed vehicle, the opening for introducing the intercooler cooling air in the bonnet is a rectangle with the long side in the longitudinal direction of the vehicle body, and an air scoop is installed to uniformly introduce the cooling air from the entire opening. There is a problem in that the height of the air scoop opening must be increased to increase the amount of air introduced to the rear of the opening. In addition, the intercooler has a predetermined distance from the inside surface of the bonnet, because the air passage is formed by the seal rubber that hangs down from the periphery of the opening for introducing the cooling air and is connected to the intercooler. There was a problem that it was difficult to secure the installation space for the intercooler.

An object of the present invention is to secure a sufficient amount of air introduced into the engine room through the cooling air intake opening without increasing the height of the air scoop provided in the bonnet, and to secure the installation space for the intercooler. An object is to provide a vehicle air intake device that can be secured.

[0005]

In order to achieve the above object, an air intake device for a vehicle according to the present invention has an intercooler installed vertically in an engine room with its longitudinal direction substantially aligned with the longitudinal direction of the vehicle body. In an equipped vehicle, a cooling air intake opening is provided at a position corresponding to the hood intercooler, and an air scoop having a front end opening is provided to cover the cooling air intake opening, and the air scoop opening width is set to the cooling air. By making it longer than the vehicle width direction dimension of the intake opening, and providing a guide member on the back surface of the air scoop that reaches the rear end of the cooling air intake opening from the air scoop opening end,
The cooling air taken in from the air scoop opening flows evenly over the entire cooling air intake opening, and sufficient cooling air is also introduced to the rear end of the vertical intercooler, increasing the air scoop height. It is not necessary to increase the width of the air scoop opening in the vehicle width direction, and a sufficient air scoop opening area can be secured. As the guide member, it is preferable to use a rib formed so as to project on the back surface of the air scoop. Further, by forming the peripheral edge of the cooling air intake opening higher than the upper surface of the bonnet and disposing the seal rubber between the rear surface of the peripheral edge and the intercooler, an intercooler installation space can be secured in the engine room.
