Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a vehicle provided with a baffle plate, and more specifically to a baffle for eliminating a water column or water splash rising to the front of the vehicle when the vehicle plunges into a shallow water. The present invention relates to a vehicle provided with a plate.

[Conventional technology]

For example, because all-wheel drive vehicles are highly mobile, they must be used as vehicles that run on construction sites where the roadbed is not maintained, quarries, unpaved roads, and wilderness. Is well known. By the way, when traveling in the above-mentioned place, the place may be flooded due to heavy rain or the like, and depending on the place, it may cross a shallow river where there is no bridge.

A vehicle that travels in this way needs to prevent water that rises when the vehicle rushes into the water from entering through the air intake port of the engine. Therefore, in a cab-over vehicle, a so-called vertical intake duct is installed in which an intake duct is erected upright between a normal driver's cab and a loading platform and an air intake is provided at a high position. However, for example, in a special vehicle such as a double cab vehicle, there is no room for installing a vertical intake duct in the middle of the vehicle body.

Therefore, it is conceivable to find a mounting location on the front part of the vehicle body, but it is difficult to provide an air intake port at a high position due to restrictions of supporting means, obstruction of the driver's view, etc. An air intake will be provided on the.

By the way, a normal cab-over vehicle has a water depth of 400 to 500 mm.
However, if a vehicle plunges into such a depth, a large amount of water can be suddenly splashed off, and a water column or splash will rise along the front part of the vehicle body. This water column or splash of water takes only a few seconds, but
During this time, the front view is blocked, which is dangerous, and there is a problem that water may enter from the intake duct provided in the front part of the vehicle body and adversely affect the air cleaner and the engine.

As a prior art for removing water droplets intruding from the air intake port of this vertical intake duct, a duct thicker than that is attached around the tip of the duct, and air containing water droplets is swirled when being sucked into the thick duct to form a peripheral wall. There is a device disclosed in Japanese Utility Model Laid-Open No. 59-545310, in which water droplets are attached to and collected on the inner surface of the thick duct to flow out from the lower end of the thick duct.

However, in this prior art, since the intake air is swirled to remove the water droplets as described above, it cannot be used in the case where a large amount of splashes are scattered for a short time as described above. Therefore, the inventor of the present invention has solved the above-mentioned problem by providing a water column or a baffle for avoiding water splashing under the air intake provided on the front surface of the cabover vehicle (Japanese Patent Application No. 62-145906).

However, depending on the vehicle grade, the ground clearance may be low. In this case, the effect of preventing water intrusion may be reduced, and there is still a need for improvement, and the water depth is 300 mm.
In the case of rushing into the water as described above, it is impossible to prevent the visibility of any vehicle from becoming instantaneously zero or being significantly deteriorated.

[Problems to be Solved by the Invention]

The present invention has been made focusing on the above problems,
Even if a cabover vehicle with a combustion air intake on the front of the vehicle is a cabover vehicle with a low ground clearance, water splashes from the air intake due to the water column or splash that rises when the vehicle enters the shallow water. Moreover, it is an object of the present invention to provide a means capable of eliminating the influence of the water column or water spray so that the driver's view is not obstructed.

[Means for Solving the Problems]

In order to achieve the above object, the structure of the vehicle provided with the baffle plate of the present invention is a baffle having a cross-sectional shape that is long in the vehicle width direction on the lower side of the front surface of the vehicle body and that the upper edge side is closer to the front of the vehicle than the lower edge side. It is characterized by attaching a plate and changing the scattering direction of the water column or water splash rising along the front of the vehicle to the front of the vehicle when the vehicle enters a shallow water or a puddle.

When a vehicle rushes into the water, a water column or water spray rises over the entire width of the vehicle.Therefore, the baffle plate having the same width as the bumper is provided directly above or below the bumper, or the shape of the bumper is the bumper shape. It may have an inclined or curved structure so as to project forward or laterally within a range that does not affect the function of.

Further, the baffle plate is arranged on the front surface of the vehicle, and as described above, since it has a shape projecting forward as it goes upward, the shape and material used are not particularly limited.
For example, it can be formed of a material that does not have an adverse effect when it collides with a person, and can be formed of a material that can be deformed within a range that can withstand water pressure, for example, an elastic material such as rubber or a foamed resin.

[Action]

As described above, when the vehicle rushes into the water, a large amount of water rises sharply along the front surface of the vehicle.However, the baffle plate of the present invention allows the water that rises vertically in the front surface of the vehicle to become more horizontal. Change and scatter. Therefore, even if the vehicle has a low ground clearance, the water column or the water spray does not obstruct the driver's forward field of view, and safety can be ensured. Further, in a vehicle having a vertical intake duct mounted on the front surface of the vehicle body, the amount of water reaching the baffle is reduced even when the above-described prior art baffle arranged under the duct cannot sufficiently bring out the effect. Therefore, the baffle that covers under the air outlet can effectively function.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings according to an embodiment.

FIG. 1 is a side view of an essential part of a cabover vehicle to which the baffle plate of this embodiment is attached, and FIG. 2 is a front view thereof.

In the figure, a cab-over vehicle C having a low vehicle height in this embodiment
A baffle plate 3 is provided on the lower side of the front surface of the operator's cab 1 in contact with the upper side of the bumper 2 and over the entire lower width of the operator's cab 1. As shown in FIG. 3, the baffle plate 3 has a cross-sectional shape that protrudes upward in the vehicle traveling direction with a gentle curve. 4 in the figure
Is a bolt for fixing the baffle plate 3 to a bracket (not shown).

As shown in FIG. 1 and FIG. 2, the cab 5 of this embodiment has a front surface protruding from a radiator grille 5,
A vertical intake duct 6 extending upward along the body is attached, and a hood 7 is attached to the tip thereof. The intake air is configured to be taken in through an opening (air intake) 11 (not shown) at the lower end of the hood 7, and the baffle 8 also serving as a bracket of the vertical intake duct 5 covers the lower side of the intake. Is provided. In the figure, 9 is a headlight, and 10 is a cutout of water.

Next, the operation of the present embodiment will be described by comparing the case where the baffle plate 3 shown in FIGS. 4 to 5 is not provided and the case of the present embodiment where the baffle plate 3 is provided.

4 to 5, when the baffle plate 3 is not provided, if the cab-over vehicle C plunges into the water,
The water column or water splashed by the bumper 2 rises along the front of the vehicle and directly hits the baffle 8. In this case, the tip 10 of the baffle 8 acts to cut back the water column, but the water flow rising to the side is pushed to the left and right,
The hood 7 is prevented from entering the water stream.

However, when the water flow passes through the left and right ends of the baffle 8 and splashes 12 occur, and when the rising water flow rate is large, the amount of the splash entering the hood 7 increases, and the front of the driver's seat 1 also increases. To block the view.

By the way, in the state shown in FIG. 6 to FIG. 7 in which the baffle plate 3 is provided, the water column that rises along the front surface of the vehicle is changed so that the direction of the water flow in which the baffle plate 3 rises is changed back to the front of the vehicle. It can slow down the flow rate and reduce the flow rate significantly. Therefore, the baffle 7 can be effectively operated, and at the same time, the front view of the driver's cab 1 can be sufficiently secured to maintain the driving safety.

[Effects of the Invention] As described above, the vehicle provided with the baffle plate of the present invention is a baffle having a cross-sectional shape that is long in the vehicle width direction on the lower side of the front surface of the vehicle body, and that the upper edge side is closer to the front of the vehicle than the lower edge side. Since the plate is attached, the water that rises when the vehicle plunges into water such as a shallow water can be scattered to the front or side to drastically reduce the amount of water that rises along the front of the vehicle. It is possible to protect the sight of the person from the water column or water splash. Furthermore, in vehicles equipped with a vertical intake duct on the front of the vehicle body, the amount of water reaching the combustion air intake on the front of the vehicle is drastically reduced, so the intake position of the air on the front of a cabover vehicle with a low vehicle height is sprayed. It is possible to obtain the effect that the device for protecting from the protection can be operated more effectively.
