Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the air intake port of an air cleaner in an automobile, particularly a cab-over type vehicle.

Conventionally, as shown in Fig. 1, the air intake port of an automobile air cleaner has been installed outside the vehicle so that the intake noise cannot be heard inside the vehicle, and furthermore, it has been installed outside the vehicle to prevent water and dust from entering the air cleaner 2 along with the intake air. The suction duct 3 is extended to open into the space below the floor behind the radiator grille 6, bumper 7, etc. at the front of the vehicle body 1, so that when driving in deep water, the suction duct 3 In order to prevent water from entering the engine cylinder by sucking water into the air cleaner 2 through the mouth, it was difficult to prevent water from entering the engine cylinder by installing a water-shielding plate 5 below the duct opening. 4 is an engine, and 8 is an instrument panel.

The present invention was devised in view of the above-mentioned conventional problems. To provide an air cleaner inlet for an automobile that can easily drain water even if water enters the inlet, and can prevent intake noise from being heard in a vehicle interior. However, the side panel extending below the door opening edge of the floor is provided with a step section for getting on and off that recesses into the inside of the vehicle body, and a duct hole and an air cleaner provided in the upper wall of the step section are provided. They are connected by an intake duct, and when the door is closed, the step section is closed by the door, and when the door is closed, air is allowed to flow between the lower part of the side panel and the inside of the door, allowing communication between the outside of the vehicle and the step section. This air cleaner is located at an air intake port of an air cleaner for an automobile, which forms an intake gap and seals a floor compartment and a door with a sealing member.

The present invention will be described below with reference to the embodiments shown in the drawings.

The vehicle body 1 is attached to a side panel 11a extending downward from the door opening edge 12a of the floor 12 of the vehicle body.
A step portion 13 is formed which is recessed inward of the step portion 1.
The step portion 13 includes a step surface 13a, a standing wall 13b that continuously rises from the step surface 13a,
A box-shaped space 14 is formed by an upper wall 13c formed from the vertical wall 13b toward the door opening edge 12a. A duct hole 15 is provided in the upper wall 13c. A dust prevention net 16 is stretched over the duct hole 15 as required. Further, an air cleaner support member 19 is attached to a support member 18 that is fixedly suspended from a side member 17 that supports the floor 12, and an air cleaner 20 is attached to the air cleaner support member 19. The air cleaner 20 and the duct hole 15 are connected by a suction duct 21 made of a tube or pipe, and the air cleaner 20 and the engine 25 are connected by an air cleaner duct 31. The step portion 13 is connected to the door 22.
When the step part 13 is closed by the door 22, the lower part of the side panel 11a and the door 22 are closed.
An air intake gap 23 of approximately 10 mm to 20 mm, for example, is formed between the inner side 22a of 2 and the step portion 13.
The inner side 22a of the door 22 is recessed so that . In this case, the side panel 11a may be retracted into the vehicle body 11 without recessing the inside 22a of the door 22. Further, as shown in FIG. 2, an air intake gap 23 may be formed at the lower part of the front part 29a or rear part 29b of the step part 13. Also, the inside 2 of the door 22
2a and the vehicle interior 30 above the floor 12 are sealed with a sealing member 24 such as a weather strip.
26 is a front tire, 27 is a front pillar, and the arrow in FIG. 2 indicates the front direction of the vehicle body 11. Note that the front pillar 27 has an air intake hole 28 on the surface where the step portion 13 is located.
Air may be taken into the step portion 13 from the front pillar 27 by providing a hole therein.

Therefore, when the door 22 is closed, the side panel 1
An air intake gap 23 is formed between 1a and the lower part of the door 22, or the front and rear parts of the door 22, and the air intake gap 2
3, air can be sucked in from outside the vehicle.
The space 14 of the step part 13 has a function as a resonator, and changes the intake sound characteristics to prevent noise.
Furthermore, due to changes in suction pressure due to water intrusion,
Water can be prevented from being sucked in. In addition, rainwater and muddy water scattered from tires etc. can be removed from the side panel 11.
It hits the inside of the body 11 of person a and is blocked. Further, the air that enters the box-shaped space 14 of the step part 13 from the air intake gap 23 is diffused in the space 14 and separated from water and air, and is then passed through the duct hole 15 and sent to the air cleaner 20 by the suction duct 21. supplied to The muddy water that has entered the step section 13 is drained out of the vehicle from the air intake gap 23 and is then drained to the air cleaner 2.
It never goes to 0. Further, intake noise generated at the step portion 13 is blocked by the seal member 24. When getting on and off, the door 22 is opened, the foot is placed on the step surface 13a of the step part 13, and the person gets on and off.

As described above, in the present invention, since the step portion on the side of the vehicle body is surrounded by the door and the side panel of the vehicle body, it is difficult for water to splash onto the step portion, so there is no need to provide a water shielding plate. Furthermore, even if water enters from the lower part of the vehicle body, the water is drained from the air intake gap provided at the lower part of the step portion, so water will not enter the air cleaner from the suction duct. Furthermore, since the space in the step section is larger than the space formed by the gap between the door and the side panel, the air that enters through the gap is diffused in the space in the step section, changing the vibration characteristics of the intake system. Since the step part and the vehicle compartment are separated by a sealing member,
It is possible to prevent intake noise from entering the passenger compartment. Furthermore, it has the effect of not impairing the ease of getting on and off the step part when getting on and off the vehicle.
