Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a component arrangement structure around an outside air introduction duct for a vehicle.

2. Description of the Related Art Examples of component arrangement structures around outside air introduction ducts used for vehicles include those shown in FIGS. 12 to 14, for example.

That is, an air cleaner 1 and a battery 2 are arranged in front of the strut housing S in the engine room, and a relay box 4 is arranged between the battery 2 and the hood lid panel 3. The air cleaner 1 is attached with an intake duct 5 that passes below the relay box 4 and extends forward (this similar structure was developed in 1983, for example).
(Listed in the Bluebird Maintenance Manual issued by Nissan Motor Co., Ltd. in September 2017).

Problems to be Solved by the Invention Since the intake duct 5 is curved below the relay box 4, ventilation resistance increases accordingly, leading to a reduction in engine output. In addition, since the tip of the intake duct 5 is oriented upward, for example, when applied to a vehicle with a short overhang (indicated by a broken line in FIG. 12), the opening of the tip should be located at a low position. Therefore, water tends to enter the intake duct 5.

Then, the intake duct 5 and the relay box 4
As a result, as shown in FIG. 14, the front fender panel 6 also becomes taller due to the need to make the hood rigid panel 3 higher. Therefore, the height dimension of the hood panel 7 is increased. It is necessary to secure it, which results in large restrictions on the design.

Therefore, this idea enables the straight arrangement of the intake duct, makes it difficult for water to enter the intake duct, shortens the overhang, and creates an outside air intake duct that can also be used to reduce the hood. It provides a surrounding parts arrangement structure.

Means for solving the problem: A bulge is provided at the tip of the hood rigid panel that protrudes to the outside of the vehicle, and a part requiring inspection is placed within this bulge, and a removable air intake is placed on the center side of the part requiring inspection. Ducts are placed.

Function: It is possible to arrange the intake duct in a straight line without being affected by the parts requiring inspection, and by arranging the parts requiring inspection and the intake duct side by side, it is possible to reduce the hood.

Also, when performing work on parts that require inspection, the intake duct must be removed.

Embodiments Hereinafter, embodiments of this invention will be described in detail with reference to the drawings, with the same reference numerals assigned to the same parts as in the conventional structure.

1 to 5, an air cleaner 1 and a battery 2 are arranged in front of a strut housing S in an engine room.

On the other hand, the hood rigid panel 3 has a bulge 8 formed at its tip that extends outward from the vehicle.
A relay box 4 as a component requiring inspection is arranged within this bulge 8. Further, a radiator core side panel 9 is attached to the front end of the hood rigid panel 3, a radiator core support upper panel 10 is attached to the upper part of the radiator core side panel 9, and a front side member 11 is attached to the lower part of the radiator core side panel 9. Each is installed. Note that 12 indicates a bumper and 6 indicates a front fender panel.

A main harness 13 is wired below the relay box 4, and a portion of the main harness 13 is connected to the relay box 4.

An intake duct 5 is attached to the air cleaner 1 and extends linearly forward through a space between the relay box 4 and the battery 2.

The intake duct 5 is configured to be detachable, for example, as shown in FIGS. 6 to 9, and is connected to the relay box 4.
When inspecting the air cleaner 1, etc., it can be removed from the air cleaner 1 for easy work.

That is, as shown in FIG. 6, a bellows part 14 is provided in the middle so that it can be inserted into the mounting part 1a of the air cleaner 1, and when it is removed, the intake duct 5 is compressed by the bellows part 14 and pulled upward. As shown in FIG. 7, the tip part 15 adjacent to the relay box 4 can be separated and removed by pulling it backwards and upwards.As shown in FIG. A structure in which the lower half 5a is movable in sections, and the lower half 5a is opened upward and removed upwards, and the air cleaner 1 is attached to the attachment part 1a using a rubber material as shown in FIG. carried out by an annular ring 16 such as
A structure in which the intake duct 5 can be removed upward by turning over the annular ring 16 can be adopted.

According to the structure of the above embodiment, the relay box 4 does not pose any obstacle when the intake duct 5 is arranged, and therefore the intake duct 5 can be set straight and the tip opening can be set at a high position. The resistance is reduced, the engine output is improved, and the possibility of water intrusion into the intake duct 5 is reduced.

In addition, even when applied to vehicles with short overhangs, the reduction in ventilation resistance and the possibility of water intrusion are similar to those mentioned above, and it also supports modeling requirements such as shortening overhangs. can do.

On the other hand, since the intake duct 5 and the relay box 4 are arranged side by side, the height of the hood rigid panel 3 can be lowered, and therefore the hood can be lowered, that is, the height of the hood panel 7 can be lowered. It is also possible to narrow down the front corner part, increasing the degree of freedom in shaping.

Due to its nature, the connection between the main harness 13, which has a large diameter and is hard, and the relay box 4 can be made on a substantially straight line, making wiring work easier, reducing the length of the main harness 13 and reducing the number of fixing points. can be achieved.

In addition, since the relay box 4 is placed inside the front fender panel 6 (inside the bulge 8 of the hood rigid panel 3), which was previously a dead space, it is possible to create a compact design with a low hood and tight corners. Even in a vehicle, the battery mounting position can be moved to the outside of the vehicle, leading to an expansion of space within the engine room, making it possible to install a large displacement engine.

Next, another embodiment of this invention will be described with reference to FIGS. 10 and 11.

In FIG. 10, a lid 4a of a relay box 4 attached to a hood rigid panel 3 via a bracket 17 is integrally molded with an intake duct 5. As shown in FIG. Therefore, since the intake duct 5 is fixed by attaching the lid 4a to the relay box 4, it is advantageous in that there is no need to provide a separate fixing point for the intake duct 5.

Further, in the embodiment shown in FIG. 11, the lid 4a of the relay box 4 integrally formed with the intake duct 5 has a rotatable structure as in the above embodiment. Therefore, this embodiment has the advantage that even when there is little space for installing and removing the intake duct 5, the intake duct 5 can be easily removed while the lid body 4a is rotated.

Incidentally, in these other embodiments, the same parts as in the above-described embodiment are given the same reference numerals, and the explanation thereof will be omitted.

Effects of the invention As explained above, according to this invention, the parts requiring inspection do not become obstacles when arranging the intake duct, making it possible to arrange the intake duct in a straight line and at a predetermined height. Therefore, it is possible to increase the engine output by reducing ventilation resistance, and there is an effect that it is difficult for water to enter the intake duct.

In addition, by placing the intake duct on the center side of the vehicle, which is a part that requires inspection, it is possible to create a low hood, and even if the overhang is shortened, simply shortening the intake duct will reduce the possibility of water intrusion. etc., there is no effect, so there is an effect that the degree of freedom in modeling is increased.

In addition, the parts requiring inspection are placed in the bulge of the hood rigid panel, making effective use of the dead space, which increases the space within the engine room, which has the advantage of being able to accommodate large-displacement engines.
