Description

[Detailed Description of the Invention] The present invention relates to an improvement of the air intake structure of an air cleaner.

Conventionally, air is sucked in from the other end of an air introduction pipe, one end of which is connected to the tip of the air intake nose of an air cleaner installed in a vehicle, and is supplied into the cylinder of the engine.
In particular, in the case where the air inlet that communicates with the other end of the air inlet pipe opens toward the front of the vehicle, the horizontal bar of the radiator grille located in front of the front of the vehicle is arranged horizontally. Therefore, when the vehicle is driven on a rainy day or through a flooded waterway due to flooding, water passes from the front of the vehicle through the gaps between the pillars of the radiator grill toward the rear of the vehicle, and proceeds to the air inlet, and then the air inlet pipe, It passes through the air cleaner and enters the intake pipe and engine cylinder.

There was a fear that water sucked in from the air inlet would cause water hammer in the intake pipe or cylinder, leading to damage to the engine.

In addition, in order to eliminate the above-mentioned problem, the horizontal bars of the radiator grille are tilted downward toward the rear of the vehicle, and the horizontal bars of the radiator grille are tilted to prevent water from entering through the gaps between the pillars of the radiator grille. It is possible to prevent the water from entering from the air inlet by redirecting the water coming from the vehicle to the bottom of the vehicle. When looking at the radiator grill from above, the interior of the engine compartment can be easily seen between the pillars of the radiator grill, which has the disadvantage of detracting from the appearance of the vehicle body.

This invention solves the above-mentioned problems, and includes an air cleaner installed in the engine compartment of a vehicle, a body panel located in front of the air cleaner and extending vertically in the direction of the main shaft, and a body panel that is attached to the vehicle. An air inlet is formed in the longitudinal direction, one end is connected to the tip of the air intake nose of the air cleaner, and the other end is attached to the vehicle rear side of the vehicle body panel so as to communicate with the air inlet. a radiator grille disposed at the front of the vehicle at a distance from the vehicle body panel and extending in a protruding direction and in a vertical direction; a direction changing member provided at a rear part of the radiator grille facing the front part of the air inlet so as not to be sucked into the air inlet, the direction changing member being formed to match the shape of the radiator grille. The main feature of the air cleaner air intake structure is that it is held on the radiator grille through a clip that prevents water from entering the air cleaner, thereby preventing engine damage caused by water. It can be prevented.

Another advantageous effect is that the same direction changing member can be attached to radiator grilles of various shapes simply by changing the shape of the clip.

An embodiment of the present invention will be described based on FIGS. 1 and 2. 1 is a headlamp support panel whose one end is connected to the tip of the air intake nose of an air cleaner (not shown) and whose other end is fixed to the vehicle body. This is an air intake introduction pipe fixed to an annular flange 4 that protrudes toward the rear of the vehicle body at the peripheral edge of an air intake port 3 provided at the upper part of the vehicle body.

Reference numeral 5 denotes a radiator grill which is fixed to the front of the vehicle in front of the air inlet 3 and to the front end of the vehicle body, and is connected to a horizontal beam 6 disposed in the horizontal direction of the vehicle body and a radiator grille arranged in the vertical direction of the vehicle body. It is composed of vertical bars 7.

8'' is a direction changing member provided on the rear side of the vehicle of the radiator grille 5 located in front of the air inlet 3;
Vertical bars 9, horizontal bars 10, and horizontal bars 1 located at both upper and lower ends of the vehicle.
0 and a clip 12 fixed with a rivet 11.

Further, the clip 12 of this embodiment has a fixing portion 13 attached to the horizontal beam 10 located at both the upper and lower ends of the vehicle of the direction changing member 8.
and a mounting part 14 that branches off from the fixing part 13 in a trifurcated shape, and a surface of the fixing part 13 and the mounting part 14.
The angle θ with respect to the surface of
It is placed facing the direction.

Therefore, to attach the integral trifurcated branch to the direction change member 8, by inserting the part 14 into the horizontal bar 6 of the radiator grille 5, the part 14 presses the horizontal bar 6 and the part 14 is attached.
Since the claws 15 bite into the horizontal beams 6, the direction changing member 8 is easily fixed to the radiator grille 5.

Note that 16 is a hood panel, and 17 is a bridge panel provided above the headlamp support panel 2.

According to the above-mentioned configuration of the present invention, even if water enters the gap 18 between the pillars of the radiator grille 5 from the front of the vehicle toward the rear of the vehicle when the vehicle is driven on a rainy day or in a flooded waterway due to flooding, etc. Since the water that has entered the vehicle is guided downward by the horizontal beam 10 of the direction change member 8 that is inclined downward toward the rear of the vehicle, the water that has entered flows toward the bottom of the vehicle. As a result, water will not enter the intake pipe or engine cylinder.
This has the effect of eliminating the risk of water hammer occurring within the same intake pipe or the same cylinder.

In addition, in the above embodiment, the clip 12 of the direction change member 8 is provided on the horizontal crosspiece 10, but a plurality of mounting holes may be drilled at any horizontal and vertical positions of the direction change member 8. At the same time, by preparing clips 12 of various shapes and selecting the mounting holes of the direction change member 8 and the clips 12 according to the shape of the radiator grille 5, the same direction change member can be attached to radiator grilles of various shapes. It is possible to attach the present invention, and it is possible to reduce the production cost by preparing only one type of direction changing member, which requires a large amount of preparation for production.

Further, in the above embodiment, the direction changing member 8 is provided with a vertical bar 9, but the vertical bar 9 does not need to be provided.

Furthermore, in the above embodiment, the horizontal bar 10 of the direction changing member 8
has been explained using a planar shape, but it may also be installed with a curved horizontal crosspiece that is convex toward the top of the vehicle and curved downward toward the rear of the vehicle. The crosspiece 10 may be provided with a groove or a linear protrusion along the longitudinal direction of the vehicle.

Further, in the above embodiment, the horizontal beam 10 of the direction change member 8 is inclined downwardly in the vehicle, but the direction change member 8
A large number of vertical bars 9 are provided, and the vertical bars are inclined to the side of the vehicle,
Headlamp support panel 2
It may also be possible to prevent water from entering the air inlet 3.

Further, the direction changing member 8 of the above embodiment has been described as having the horizontal beam 10 and the vertical beam 9, but instead of providing the pillars, a large number of through holes are formed in a thick flat plate that is inclined downwardly of the vehicle. A direction changing member may be provided.
