BACKGROUND OF THE INVENTION
The present invention relates to an inner member of a hood panel that covers an upper portion of an engine provided in a front portion of a vehicle. More specifically, the present invention relates to an inner member for reinforcing a hood panel formed so as to be able to be joined to the inner surface of the hood panel.
[0002]
[Prior art]
Conventionally, a hood panel is attached to a vehicle such as a passenger car in which an engine is provided at the front portion of a chassis frame so as to cover an upper portion of the engine. Here, in general, in a vehicle equipped with a turbocharged engine, the temperature of the supercharged air from the turbocharger is forcibly lowered by an air-cooled intercooler to increase the air density, whereby each cylinder of the engine The engine efficiency is increased to improve the engine output. In order to effectively introduce the outside air to the air-cooled intercooler, as shown in FIGS. 8 and 9, the portion of the hood panel 1 (bonnet) facing the intercooler 2 (FIG. 8) is bulged upward. An intercooler duct is known in which an air intake 3 is opened at the front end of the bulging portion 1a, and outside air taken in from the air intake 3 is immediately introduced into the intercooler 2 (for example, Patent Document 1). reference.).
[0003]
As shown in detail in FIG. 8, an air intake grill 4 made of a resin molded product is attached to the air intake 3, and a reinforcing inner for preventing distortion of the hood panel 1 on the inner surface of the hood panel 1. The member 6 is joined. The reinforcing inner member 6 includes a first inner member 6a that intersects at a portion where the air intake grille 4 is attached, and a second inner member that intersects at a portion corresponding to the rear portion of the bulging portion 1a and extends in the vehicle width direction. 6b. A portion of the first inner member 6a facing the air intake grille 4 is formed to be recessed, and the air intake grille 4 is screwed into the recess, and the second inner member 6b extends along the inner surface of the bulging portion 1a. It is formed to be curved.
[0004]
On the other hand, a vehicle in which the hood panel 1 is extended upward to open the air intake 3 and the air intake grille 4 is attached thereto is known to the vehicle user as having the intercooler 2 and has a special shape. Due to the nature, the number of customers who require the hood panel 1 with the air intake grille 4 attached is increased even though the intercooler is not actually provided. However, if the air intake 3 is opened in the hood panel 1 even though the intercooler 2 is not provided, unnecessary rainwater and dust enter the engine room from the air intake 3 and contaminate the engine room. There is a bug that ends up.
[0005]
In order to eliminate this point, a hood panel that does not have an air intake opening is attached to a molded product that simulates the bulging part and the front end of the bulging part simulates an air intake grille. There has been proposed a hood panel that does not have an air intake opening, in which a bulge is added by post-processing, and a molded product imitating an air intake grille is attached to the opening. In these cases, the external appearance of the intercooler looks like a mounted vehicle, but no air intake is formed, so unnecessary rainwater or dust may enter the engine compartment. The situation can be avoided.
