Description

[Detailed explanation of the idea] The present invention relates to an air intake structure for an automobile.

In conventional cab-over type vehicles, it is difficult to mount the air cleaner directly above the engine due to interior space constraints. Therefore, it is recommended to mount the air cleaner near the engine, in front of or behind the front tires. It is customary.

In this case, it is necessary to take in clean air, so a duct is taken out from the air cleaner, directed upwards, and a dust-proof and waterproof cover is attached to the inlet, or the duct is extended upward to the outer skin of the vehicle body. An air intake structure is adopted in which the inlet end of the duct is connected to an air intake port provided by forming a slit in the outer panel.

However, in such conventional air intake structures, since the air intake is close to the tires, it is not possible to completely prevent water from entering, or because slits are formed in the outer skin of the car body, rain or It also has the disadvantage that water gets in when washing the car.

SUMMARY OF THE INVENTION The present invention aims to address the drawbacks of conventional air intake structures as described above and to provide an improved air intake structure.

According to the present invention, this purpose is to insert and fit an end of a sight rail arranged in the longitudinal direction of the vehicle into an opening of a cross member made of a groove-shaped member arranged at the front end of the vehicle and extending in the vehicle width direction. Then, the two members are joined together, and a hollow part formed by closing a part of the cross member opening on both sides of this insertion position, and a wall part of the cross member located on the opposite side of the wheel. an air intake hole formed on one of both sides of the insertion position and at a position opening into the hollow part; and an air intake hole formed on the other side of both sides of the insertion position. It includes a port connected to the inlet of the intake air cleaner, and an opening formed at the end of the site rail that communicates the hollow parts on both sides of the insertion position, and the air taken in from the air intake is This is achieved by an air intake structure of the motor vehicle, which is configured to be drawn into the air cleaner through a hollow space in the gas member.

FIG. 1 of the accompanying drawings is a perspective view showing one embodiment of an air intake structure for an automobile according to the present invention.

In the figure, 1 is one of the sight rails arranged in parallel in the longitudinal direction of the vehicle on the vehicle frame, and 2 is the left front wheel or front tire.

A cross member 3 is provided that extends in the vehicle width direction and connects the front end of the sight rail 1 and another sight rail that is arranged in parallel with the sight rail and is not shown in the drawings.

The cross member 3 has conventionally been constructed as a simple groove-shaped member, but according to the present invention, the cross member 3 has a cross section taken along the lines ■-■ and I-1 in FIG. As better shown in FIGS. 2 and 3, it has a partially closed hollow box-shaped cross-sectional structure.

That is, in this case, the cross member 3 includes an outer channel 4, which is a groove-shaped part/material that forms the main part, an inner channel 5 and a corner gusset 6, which close the opening edge of a part of the outer channel. 4. A closed hollow part 7 is formed in the part where the inner channel 5 and the corner gusset 6 cooperate.

The cross member 3 is provided with an air intake port 8 that opens into the hollow portion 7 in the wall portion of the opposite side of the front tire 2 adjacent to the cross member 3, and an air intake port 8 that opens into the hollow portion 7 at a position apart from the air intake port. Similarly, a port 9 is bored at a position opening into the hollow portion 7.

Port 9 communicates with air intake 8 via hollow space 7 .

In the illustrated embodiment, the tip of the sight rail 1 extends so as to cross the middle of the hollow portion, but the tip of the sight rail has a number of through holes not shown in the figure. As a result, the hollow part 7 allows air to flow from one end where the air intake port 8 is provided to the other end where the port 9 is provided, but rainwater, washing water, etc. It is designed to provide a draining effect to prevent water from passing through.

10 is an air cleaner for purifying intake air to the engine.

The air intake 11 of the air cleaner is connected to the port 9 via the duct 12, thereby allowing the air intake 8
The air introduced into the hollow part 7 passes through the hollow part and reaches the port 9, from which it passes through the duct 12 and flows into the air cleaner 10 from the inlet 11.The air purified here passes through the duct 13 and enters the engine. It is designed to lead you to.

According to this configuration, as is clear from the figure, even though the air intake conduit to the air cleaner is extremely short like the duct 12, the air intake from the outside can be
Like the air intake port 8, it can be opened at a sufficient distance from the front tire 2 and in the opposite direction across a barrier from the front tire, and is clean and free from being affected by mud splashing from the tires. Dry air can be taken in.

The air intake port 8 is blocked from hot air from the engine by the cross member body, especially the corner gazette 6, and can take in air that is not affected by the hot air from the engine.

Also, of course, with respect to the air intake port 8 which opens at the position shown in the cross member, there is little risk of water getting into it when it rains or when the car is washed.

Furthermore, even if some water enters through the air intake port 8, the water will flow through the front end of the sight rail 1, which is formed with a number of through holes extending halfway through the hollow portion 7 from the air intake port to the port 9. The water draining effect prevents water from reaching the port 9, and the risk of water entering the air cleaner 10 is greatly reduced.

Thus, it will be understood that according to the present invention, an automobile air intake structure with a simple structure and excellent dustproof and waterproof properties can be obtained.

Further, according to the present invention, a part of the cross member is configured to have a hollow box-shaped cross-sectional structure including the inner channel 5 and the corner gussets 6, so that the strength and rigidity of the cross member is increased, and the corner gussets 6 In some cases, the strength of the bond between the cross member and the sight rail is also increased, and improvements in frame strength, rigidity and durability are achieved.

Although one embodiment of the automobile air intake structure according to the present invention has been described in detail above, various different embodiments may be made within the scope of the present invention as the position of the air cleaner and other conditions change. It will be obvious to those skilled in the art that this is possible.
