Description

The present invention relates to a vehicle intake device that allows air to be sucked in to be sent to the vehicle's internal combustion engine.

In vehicles such as automobiles, air is required for the air-fuel mixture used in internal combustion engines such as engines. For this reason, the vehicle has an intake system that is configured to be able to draw in the air used in the internal combustion engine, and typically the intake system has an intake duct that sends air taken in through an intake port at the front of the vehicle to the internal combustion engine.

However, when a vehicle is flooded or submerged in water, there is a risk that water or other foreign matter may enter the internal combustion engine through the intake port of the intake duct and into the inside of the intake duct. In this case, the internal combustion engine may break down due to the foreign matter. For this reason, various intake devices have been proposed that can prevent foreign matter from entering the internal combustion engine.

One example of such an intake device is an intake device in which an intake duct defines the front of a compartment located at the front of the vehicle in the longitudinal direction of the vehicle, overlaps with a front bumper cover formed to surround the front grille in a front view of the vehicle, has an air intake (intake port) that opens toward the front of the vehicle, and has an air outlet passage that extends toward the rear of the vehicle above the upper end of the air intake port and communicates with the power unit, and the air intake port is located below a cross member that extends in the vehicle width direction along the rear surface of the front bumper cover in the longitudinal direction of the vehicle. (See, for example, Patent Document 1, especially Figure 4 thereof.)

JP 2019-077269 A

However, in one example of the intake system described above, if water or other intrusions that have entered the compartment from the front grille block the intake port, particularly when the vehicle is submerged or flooded, there is a risk that the intrusions will be sucked into the internal combustion engine through the intake duct due to the negative pressure of the internal combustion engine. Therefore, it is desirable to reliably prevent such intrusions from entering the internal combustion engine.

In addition, in one example of the intake device described above, the intake port is located below the cross member, so that when the vehicle is flooded or submerged, foreign objects can easily reach the intake port. In such a configuration, if the intake port is moved upward on the vehicle, the cross member must also be moved upward on the vehicle along with the intake port. In this case, there is a problem that the vehicle becomes larger. Therefore, when improving the intake duct to reliably prevent foreign objects from entering the internal combustion engine, it is also essential to prevent the vehicle from becoming larger.

In light of this situation, it is desirable for vehicle intake systems to reliably prevent water and other intrusions from passing through the intake duct into the internal combustion engine and to prevent the vehicle from becoming larger.

In order to solve the problem, a vehicle intake device according to one embodiment of the present invention comprises an intake duct configured to send air to an internal combustion engine of a vehicle, and a cross member disposed at the front of the vehicle and extending in the width direction of the vehicle, the intake duct being disposed to face the cross member in the fore-and-aft direction of the vehicle and attached to the cross member, the cross member being disposed between a front wall located toward the front of the vehicle and a rear wall located toward the rear of the vehicle relative to the front wall, the cross member being disposed between a front wall located toward the front of the vehicle and a rear wall located toward the rear of the vehicle ... and a rear wall, the lower end of the front wall is located lower than the lower end of the rear wall, the intake duct has a first intake port and a second intake port that open to allow air to be drawn into the intake duct, the first intake port is formed at the upstream end of the intake duct in the flow direction of air passing through the intake duct and is disposed on the rear side of the vehicle relative to the front wall, and the second intake port is formed downstream in the flow direction of the first intake port, above and to the rear of the first intake port, and is disposed on the rear side of the vehicle relative to the rear wall.

In one embodiment of the vehicle intake system, water and other intrusions can be reliably prevented from entering the internal combustion engine through the intake duct, preventing the vehicle from becoming larger.

The vehicle has a front panel 6 located at its front end. The front panel 6 can be located between the intake device 1 and the front grill 5 in the front-rear direction. The front panel 6 has an inclined wall 6a located behind the front grill 5. The inclined wall 6a inclines so as to rise upward as it moves from the rear to the front. The inclined wall 6a is formed so as to guide air that has entered the engine room 4 through the front grill 5 to the first intake port 11 of the intake duct 10. As shown in FIG. 2, the vehicle has a radiator 7 located at the front end of the engine room 4. As shown in FIG. 1, the vehicle has an engine hood 8 that covers the engine room 4 from above.

"Details of the intake duct"
2 to 7, the intake duct 10 can be configured in detail as follows. The intake duct 10 can be made of resin. Furthermore, the intake duct 10 can be an assembly formed by assembling a plurality of parts made of resin. These plurality of parts can be resin injection molded products. However, the material used for the intake duct is not limited to resin.

As shown in FIG. 2, the intake duct 10 has a fourth intake section 16 that connects the delivery port 15e of the third intake section 15 to the air cleaner 3. In the intake duct 10, the first intake section 13, the second intake section 14, the third intake section 15, and the fourth intake section 16 are arranged in this order from upstream to downstream in the air flow direction. The first to third intake sections 13 to 15 are arranged in the intake side region 10b of the intake duct 10 in the flow direction.

As shown in Figure 3, the lower end 11a of the first air intake 11 is located below the lower end 21a of the front wall 21 of the cross member 20. The lower end 11a of the first air intake 11 can be positioned at the lowest position in the air intake duct 10. The lower end 11a of the first air intake 11 is located above the lower end 5b of the front grille 5. The upper end 11b of the first air intake 11 is located above the lower end 21a of the front wall 21 of the cross member 20.

The first air intake 11 faces the rear wall 22 and the rear flange 23 (described later) in the vertical direction, and is located below the rear wall 22 and the rear flange 23. The longitudinal distance between the first air intake 11 and the front wall 21 of the cross member 20 is greater than the vertical distance between the first air intake 11 and the rear wall 22 and the rear flange 23 of the cross member 20.

As shown in FIG. 7, the second air intake 12 opens toward the front. Referring to FIGS. 3, 4, and 7, the lower end 12a of the second air intake 12 is located above the lower end 22a of the rear wall 22 of the cross member 20. The upper end 12b of the second air intake 12 is located below the lower end 22a of the rear wall 22 of the cross member 20. The opening area of the second air intake 12 is smaller than the opening area of the first air intake 11. During normal vehicle operation, the amount of air taken into the air intake duct 10 from the first air intake 11 is greater than the amount of air taken into the air intake duct 10 from the second air intake 12.

As shown in FIG. 7, the first intake section 13 is disposed horizontally. The downstream portion 13a of the first intake section 13 extends in the front-rear direction. The upstream portion 13b of the first intake section 13 in the flow direction extends in the vehicle width direction.

In the first intake section 13, the cross section of the downstream section 13a is smaller than the cross section of the upstream section 13b. In the first intake section 13, the length of the downstream section 13a in the front-rear direction is longer than the length of the upstream section 13b in the vehicle width direction. A first rib 17 protruding from the outer surface of the intake duct 10 is formed along the boundary between the upstream section 13b and the downstream section 13a of the first intake section 13.

The upstream portion 14c of the second air intake section 14 in the flow direction extends in a curved manner rearward and upward from the downstream portion 13a of the first air intake section 13. The downstream portion 14b of the second air intake section 14 extends in a curved manner upward from the upstream portion 14c of the second air intake section 14 toward one side of the vehicle width direction. The second air intake port 12 is disposed in the downstream portion 14b of the second air intake section 14. The entire length of the second air intake section 14 along the air flow is shorter than the entire length of the first air intake section 13 along the air flow.

The third intake section 15 extends in a curved manner from the downstream portion 14b of the second intake section 14 toward one side in the vehicle width direction and toward the rear. The front portion 15a of the third intake section 15 communicates with the downstream portion 14b of the second intake section 14 in the vehicle width direction. The third intake section 15 is inclined so as to rise upward as it moves from the front to the rear. The third intake section 15 is inclined relative to the horizontal direction.

A second rib 18 protruding from the outer surface of the intake duct 10 is formed along the boundary between the downstream portion 14b of the second intake portion 14 and the front portion 15a of the third intake portion 15. With reference to Figures 3 to 7, the mounting portion 15b of the third intake portion 15 is located above the rear flange 23 of the cross member 20.

The mounting portion 15b of the third intake section 15 abuts against the rear flange 23 of the cross member 20 in the vertical direction and is attached to the rear flange 23 by a joining means. The joining means can be a fastening means such as a bolt and a nut. However, the joining means can also be a means other than a fastening means.

"Cross member details"
2 to 6, the cross member 20 can be configured in detail as follows. The cross member 20 is made of metal. The cross member 20 can be a press-formed product made by press-forming a metal sheet. However, the material used for the cross member is not limited to metal.

Although not specifically shown, the cross member 20 has a locking mechanism for the engine hood 8. The upper part of the radiator 7 is attached to the cross member 20. With reference to Figures 2 and 3, the cross member 20 is located toward the front end and toward the upper end of the engine room 4. Such a cross member 20 can be an upper cross member 20 in the engine room 4.

The lower end 21a of the front wall 21 of the cross member 20 is located below the upper end 5c of the front grille 5. The upper end 21b of the front wall 21 of the cross member 20 is located below the upper end 5c of the front grille 5. The cross member 20 has a rear flange 23 that protrudes rearward from the lower end 22a of its rear wall 22. The cross section of the cross member 20 can be formed into a generally hat shape.

"Air flow around the intake system"
2 and 3, air can flow in and around the intake device 1 as follows: In particular, while the vehicle is running, air flows from the outside in front of the vehicle into the engine compartment 4 through the opening 5a of the front grille 5.

Air that passes through the opening 5a of the front grille 5 passes under the front wall 21 of the cross member 20 to reach the first air intake 11 of the air intake duct 10. Air that passes through the opening 5a of the front grille 5 passes under the front wall 21 of the cross member 20, then goes around to the rear of the front wall 21 and can reach the second air intake 12. When the air that enters the first air intake 11 passes through the first air intake section 13 and reaches the second air intake section 14, it merges with the air that enters the second air intake 12.

The air from the second intake section 14 that has merged in this way flows from the third intake section 15 to the fourth intake section 16, and then reaches the air cleaner 3. The air that reaches the air cleaner 3 is further purified by the air cleaner 3, and then sent to the engine 2.

As described above, the vehicle intake device 1 according to this embodiment includes an intake duct 10 configured to send air to the internal combustion engine 2 of the vehicle, and a cross member 20 disposed at the front of the vehicle and extending in the width direction of the vehicle, the intake duct 10 being disposed to face the cross member 20 in the longitudinal direction of the vehicle and attached to the cross member 20, the cross member 20 having a front wall 21 located toward the front of the vehicle, and a rear wall 22 facing the front wall 21 in the longitudinal direction of the vehicle and located rearward of the vehicle relative to the front wall 21, The lower end 21a of the front wall 21 is located below the lower end 22a of the rear wall 22, the intake duct 10 has a first intake port 11 and a second intake port 12 that open to allow air to be drawn into the intake duct 10, the first intake port 11 is formed at the upstream end 10a of the intake duct 10 in the flow direction of air passing through the intake duct 10 and is disposed on the rear side of the vehicle relative to the front wall 21, and the second intake port 12 is formed downstream of the first intake port 11 in the flow direction and above and rearward of the first intake port 11, and is disposed on the rear side of the vehicle relative to the rear wall 22.

In this type of intake device 1, even if the first intake port 11 at the upstream end 10a of the intake duct 10 is blocked by water or other intrusions when the vehicle is flooded or submerged, air can be taken into the inside of the intake duct 10 from the second intake port 12 formed above and to the rear of the first intake port 11. Furthermore, even if the intrusion that blocked the first intake port 11 enters the inside of the intake duct 10 due to the negative pressure of an internal combustion engine 2 such as the engine 2, the intrusion can be discharged to the outside of the intake duct 10 from the second intake port 12.

Furthermore, the lower end 21a of the front wall 21 of the cross member 20 is located lower than the lower end 22a of the rear wall 22 of the cross member 20, the first intake port 11 is disposed on the rear side of the vehicle relative to the front wall 21, and the second intake port 12 is disposed on the rear side of the vehicle relative to the rear wall 22. Therefore, the first and second intake ports 11, 12 can be moved further upward to prevent the intrusion of water and other invading objects while overlapping with the cross member 20 in the fore-and-aft direction. Therefore, in the intake device 1 according to this embodiment, it is possible to reliably prevent invading objects from entering the internal combustion engine through the intake duct 10, and to prevent the vehicle from becoming larger.

In the intake device 1 according to this embodiment, the first intake port 11 opens toward one side in the width direction of the vehicle, and the intake duct 10 has a first intake section 13 that extends from its upstream end 10a toward the other side in the width direction of the vehicle and then curves toward the rear of the vehicle, and a second intake section 14 that rises from a downstream section 13a in the flow direction of the first intake section 13, and the second intake port 12 is located in the front section 14a of the second intake section 14 that faces the front of the vehicle.

Here, water and other intruding objects that splash around the vehicle while it is moving move in the front-to-rear direction of the vehicle but are unlikely to move in the width direction of the vehicle, whereas air that flows around the vehicle while it is moving, i.e., the wind caused by the vehicle's movement, moves in the front-to-rear direction of the vehicle but is likely to move in the width direction of the vehicle. In contrast, in the intake device 1 according to this embodiment, the first intake port 11 of the intake duct 10 opens in the width direction of the vehicle, so that it is possible to allow air to enter the inside of the intake duct 10 from the first intake port 11 while preventing intruding objects from entering the inside of the intake duct 10 from the first intake port 11.

The first intake section 13 of the intake duct 10, together with the cross member 20, can efficiently block intrusions such as water that splash toward the second intake port 12 of the intake duct 10 that opens to the front of the vehicle. As a result, it is possible to efficiently prevent intrusions from the second intake port 12 through the intake duct 10 toward the internal combustion engine 2. Furthermore, the first and second intake sections 13, 14 can be formed compactly while avoiding the cross member 20. This prevents the intake duct 10 from becoming larger, and also prevents the vehicle from becoming larger.

In the intake device 1 according to this embodiment, the intake duct 10 has a third intake section 15 that extends from the downstream portion 14b of the second intake section 14 in the flow direction to the same side as the first intake port 11 in the width direction of the vehicle, and the third intake section 15 has a mounting portion 15b that protrudes from the front portion 15a of the third intake section 15 that faces the front of the vehicle toward the cross member 20, the mounting portion 15b of the third intake section 15 is attached to the cross member 20, and the lower end 15c of the mounting portion 15b of the third intake section 15 is located below the lower end 12a of the second intake port 12.

In this type of intake device 1, the third intake section 15 extends from the downstream portion 14b of the second intake section 14 in the flow direction to the same side of the vehicle as the first intake port 11 of the first intake section 13, and the mounting portion 15b of this third intake section 15 is attached to the cross member 20, so the intake duct 10 can be arranged compactly around the cross member 20. This prevents the intake duct 10 from becoming too large, and also prevents the vehicle from becoming too large.

In addition, because the lower end 15c of the third intake section 15 is located lower than the lower end 12a of the second intake port 12, the mounting portion 15b of the third intake section 15 can effectively block intrusions such as water that splash toward the second intake port 12 of the intake duct 10 that opens to the front of the vehicle. As a result, it is possible to effectively prevent intrusions from passing from the second intake port 12 through the intake duct 10 toward the internal combustion engine 2.

In the intake device 1 according to this embodiment, the third intake section 15 has an outlet 15e at the rear 15d of the third intake section 15 facing the rear of the vehicle, which opens so that air can be sent from the third intake section 15 to the internal combustion engine 2, and when viewed in the longitudinal direction of the vehicle, the outlet 15e is positioned so as to be offset from the second intake port 12 to the same side as the first intake port 11 in the width direction of the vehicle.

In this type of intake device 1, even if water or other intruders enter the intake duct 10 from the second intake port 12, the intruders are unlikely to be sent to the internal combustion engine 2 through the delivery port 15e. This makes it possible to efficiently prevent water from entering the internal combustion engine 2.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and the present invention can be modified and changed based on its technical concept.
