Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for arranging a vehicle air intake duct in a passenger car or the like, and particularly relates to an air intake structure.

(Prior Art) Generally, the engine room of various vehicles is provided with an air cleaner that supplies clean air to the engine. The air cleaner takes in outside air that has flowed into the engine room, removes dust from the air, and then sends clean air to the engine. In addition to those that suck air directly from the main body, there are also those that suck air through an intake duct. There is something that has been done.

The arrangement structure of this intake duct is such that an air intake box having an air intake in the upper part is attached to the fender skirt that partitions the engine room and the tire house, and the air intake box has an air intake box that penetrates the fender skirt inside the air intake box. An air intake duct is introduced, and its intake port is opened into the air intake box. The air flowing between the fender skirt and the fender panel is sucked in through the intake duct and purified.

(Problem to be solved by the invention) In the above-described arrangement structure of the intake duct, the through hole of the intake duct drilled in the fender skirt is formed exclusively for the intake duct, and only the intake duct is penetrated. . However, various harnesses of the electrical system must be passed through the fender skirt, etc., and if dedicated through holes were provided for each, there was a drawback that a large number of holes would have to be drilled. In particular, since the fender skirt forms the front body, it is necessary to maintain a predetermined strength, and the fender skirt has the disadvantage that the strength decreases as the number of through holes increases.

In addition, if the top of the air intake box is open, rainwater etc. can easily enter.In particular, recent car designs tend to lower the bonnet line, which results in lowering the intake port of the intake duct. When driving on a rough road surface, the vehicle tends to suck in water along with air, causing problems such as liquid compression.

In view of this, the present invention focuses on the fact that the wheel apron has an opening for harness insertion, and an intake duct is passed through the opening that is drilled in the wheel apron and through which the harness also passes, and the intake duct is inserted into the intake duct. By surrounding the intake port and the opening with an intake chamber member, the purpose is to reduce the opening of the wheel apron and to reliably prevent water and the like from being sucked in.

(Means for Solving the Problems) In order to achieve the above object, the means taken by the present invention are based on a vehicle in which a harness insertion opening is formed in the wheel apron. An intake duct is passed through the opening. Furthermore, a box-shaped intake chamber member surrounding the intake port of the intake duct and the opening is attached to the wheel apron.

(Function) With the above configuration, in the present invention, the intake duct sucks air from the outside of the wheel apron through the intake chamber member. Since the intake port of the intake duct is surrounded by the intake chamber member, the suction of rainwater and the like is reliably prevented. Further, since the intake duct is passed through the harness insertion opening, the number of openings in the wheel apron can be reduced, and a decrease in strength of the wheel apron can be reduced. Furthermore, the reduction in strength of the wheel apron due to the opening is reinforced by the intake chamber member.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

As shown in Figures 1 to 4, reference numeral 1 is an engine room in various vehicles such as passenger cars, and is surrounded by bodies 2 on both sides and a front body 3, and the upper part is covered with a bonnet 4 that can be opened and closed. It is structured according to the following.

Although not shown, the engine room 1 houses an engine, an engine cooling radiator, and the like, and also houses an air cleaner 5. As is well known, the air cleaner 5 sucks air from inside the engine room 1, removes dust from the air to produce clean air, and sends this clean air to the engine. An intake duct 6 is connected to the intake side of the air cleaner 5 so that air is sucked through the intake duct 6. In addition, in the engine room 1,
Although not shown, electrical system equipment such as a battery is also housed, and this electrical system equipment is connected by a harness 7 to an operating section of an instrument panel, a headlight, etc. in the vehicle interior.

On the other hand, the front body 3 is composed of a radiator shroud 8, a front skirt 9, etc., and is continuously attached and supported by the side body 2. Further, the side body 2 has a gap inside the front fender 10 and the wheel apron 11
are connected to each other, and a mud guard 12 is connected to the lower part of the front fender 10 and wheel apron 11. A front frame 13 is joined to the wheel apron 11 to support the side body 2, and a gap 14 is formed by being surrounded by the front fender 10, wheel apron 11, and mound guard 12. .

A bulging portion 15 is formed in the front portion of the wheel apron 11 and protrudes toward the void portion 14 side. The bulging portion 15 has a substantially U-shaped cross section with an upper plate 15b and a lower plate 15c connected to both upper and lower ends of the side plate 15a, and the rear end slopes gently inward. The interior of the portion 15 constitutes a bulging space 16 of the engine room 1. Further, a vertical plate 17 is connected downward to the inner end of the lower surface plate 15c in the bulged portion 15, while an inverted L-shaped refraction plate 18 is connected to the inner end of the upper surface plate 15b.
The inner surface of the vertical plate 17 is joined to the front frame 13 to form the wheel apron 11.
is supported, and the front fender 10 is joined to the refraction plate 18 at its upper side.

An opening 19 is formed in the top plate 15b of the bulging portion 15, and an intake chamber member 20 is attached to the top surface, that is, the cavity 14 side. The opening 19 is formed into an oval shape that is slightly elongated in the longitudinal direction of the vehicle body, into which the suction end of the intake duct 6 is inserted, and the opening 19 opens into the bulging space 1 of the engine room 1.
6 and penetrates into the cavity 14. Further, in the opening 19, the intake duct 6 is arranged at the rear with a gap in the front part, and the harness 7 passes through the opening 19 using this gap to connect the engine room 1 and the wheel apron 11. It is arranged across the cavity 14 which is the outside.

The intake chamber member 20 is configured to surround the opening 19 and the intake port 6a of the intake duct 6, and has left and right side plates 20b, 20 on the top plate 20a.
c and the front plate 20d are connected to form a box shape with an open rear surface. Furthermore, the above-mentioned both side plates 2
A flange 20e is connected to the lower ends of 0b, 20c and the front plate 20d, and is joined to the upper plate 15b at the periphery of the opening 19 at the flange 20e, thereby forming an intake chamber 20f inside. A suction port 6a of the suction duct 6 is opened in the suction chamber 20f to suck air through the gap 14 and the suction chamber 20f. Further, the harness 7 is led out from the intake chamber 20f to the cavity 14 through the open rear surface of the intake chamber member 20.

Therefore, air flows into the gap 14 surrounded by the front fender 10, wheel apron 11, muzzle guard 12, etc. through the opening 19, etc.
When the engine is driven while driving, the air gap 14
The air inside is supplied to the intake port 6 of the intake duct 6 through the intake chamber 20f from the rear open part of the intake chamber member 20.
It will be sucked in from a. Then, the air cleaner 5 removes dust from the air to produce clean air, and sends this clean air to the engine.

During this air intake, the suction port 6a of the intake duct 6
is surrounded by an intake chamber member 20, which reliably prevents rainwater and the like from being sucked in.

Further, the opening 19 is originally used as an insertion hole for the harness 7, and since the intake duct 6 is inserted into the opening 19, it is not necessary to form an opening exclusively for the intake duct 6. Since the intake chamber member 20 is joined to the upper surface plate 15b of the bulging portion 15 surrounding the opening 19, the reduction in strength due to the opening 19 is reinforced by the intake chamber member 20. Become.

On the other hand, when wiring the harness 7, when the harness 7 is inserted from the rear open part of the intake chamber member 20, the top plate 20a of the intake chamber member 20 serves as a guide, and the harness 7 passes through the opening 19 and enters the engine room 1. It will be easily introduced. Also, conversely, harness 7 is more important than engine room 1.
Even in the case where the intake chamber member 20 serves as a guide, the intake chamber member 20 can be easily guided.

Although the opening 19 in this embodiment is formed in the bulge 15 of the wheel apron 11, the opening 19 of the present invention is not limited to the bulge 15 and may be formed in the wheel apron 11.

(Effect of the invention) As described above, according to the arrangement structure of the vehicle air intake duct of the present invention, the air intake duct is passed through the harness insertion opening of the wheel apron, and the intake port and the opening of the air intake duct are surrounded. Since the intake chamber member is attached to the wheel apron, it is possible to reliably prevent rainwater and the like from being sucked in from the intake duct, thereby preventing the occurrence of liquid compression.

Moreover, since the opening is also used as an insertion hole for the harness of the electrical system, the number of openings in the wheel apron can be reduced, and a decrease in the strength of the wheel apron can be prevented.

Furthermore, since the intake chamber member is attached, the peripheral edge of the opening can be reinforced, and the wheel apron can maintain sufficient strength.
