Description

[Detailed Description of the Invention] This invention relates to a wheel house for an automobile, and more particularly to a wheel house for an automobile that suppresses icing in and around the wheel house.

In cold regions, when the atmospheric temperature is below freezing,
In addition, when snow melts due to direct sunlight and there is water on the road, when a car drives on this road, the water on the road adheres to the underside of the car and freezes, that is, forms icing.

In particular, a rear wheel house 2 and a front wheel house 3 of a car 1 are shown in FIG.
Water on the road is kicked up or thrown up by the rear wheels 4 and front wheels 5, respectively, resulting in a large amount of icing.

For example, in the rear wheel house 2 and its vicinity, as shown in FIG. 2, the suspension parts 6 are arranged close to the body side inner wall 7 of the rear wheel house 2, Water blown up from the road adheres to the interior of the vehicle, causing a large amount of ice S to form on the entire surface of the vehicle, as shown in FIG.

When icing occurs near the wheel house, the apparent distance between the suspension parts 6 and the inner wall 7 on the body side becomes narrower by the thickness of the icing, and therefore, these may interfere with each other while the vehicle is running. This may cause inconveniences such as the generation of abnormal noise and deterioration of riding comfort.

Also, on the front wheel house 3 side, water splashed forward by the front wheel 5 while the car is running may be directly or directly splashed onto the front wheel house 3.
Due to the airflow inside, a large amount of ice adheres to the suspension parts 8 or the inner wall 9 of the body side (see FIG. 4), causing the same problem as in the rear wheel house 2 described above.

This invention was made to solve the above-mentioned disadvantages, and was designed to suppress the accumulation of ice on the wheel house and its vicinity, thereby preventing the generation of abnormal noise and deterioration of ride comfort. The purpose is to provide a wheel house.

With respect to the main air flow along the body-side inner wall surface of the wheel house in the wheel house while the vehicle is running, this invention provides air flow from the inner wall surface at the front-rear center of the wheel house and at a position upstream of the suspension parts. The above object is achieved by forming a vertically protruding portion that protrudes outward all the way to the bottom surface of the body.

Further, the present invention achieves the above object by arranging the protrusion in the automobile wheel house so that the position in the longitudinal direction is behind the center of the rear wheel.

Further, the present invention achieves the above object by arranging the protrusion in the automobile wheel house so that the protrusion is positioned forward of the center of the front wheel.

Embodiments of the present invention will be described below with reference to the drawings. Here, in these drawings, the same or corresponding parts as in FIGS. 1 to 4 are given the same reference numerals.

FIG. 5 is a perspective view showing an embodiment in which the present invention is applied to the rear wheel house 2 of the automobile 1.

This embodiment is arranged at a position upstream from the central part in the longitudinal direction of the wheel house and the suspension part 6, with respect to the main air flow along the body side inner wall 7 of the rear wheel house 2 while the car is running. At a position rearward of the center of the rear wheel 4, a vertical protrusion 10 is formed that protrudes outward from the body-side inner wall 7 and extends all the way to the bottom surface of the body.

That is, in the rear wheel house 2, while the car is running, as shown in FIG.
Due to the rotating rear wheel 4, a strong air flow A is generated from the rear end of the rear wheel house toward the front and upper side.In particular, the air flow B along the body side inner wall 7 becomes a strong flow toward the front of the vehicle. Flow B
In contrast, the protrusion 10 is arranged upstream of the center of the rear wheel 4.

Since the protrusion 10 is disposed forward, ie, on the downstream side, when viewed from the rear end of the rear wheel house 2, the air flow B along the body side inner wall 7 is caused by the protrusion 10 as shown in FIG. As shown,
After the flow separation C occurs, it continues further forward. At this time, some of the water contained in the air flow B collides with the protrusion 10 and then falls along the protrusion 10 due to its own weight.

Since the lower end of the protruding portion 10 reaches the bottom surface of the body, most of it falls onto the road surface, and only a very small amount is picked up by the air flow D and adheres to the body side again. Furthermore, since the distance from the protruding portion 10 to the inner wall 7 in the width direction of the vehicle body is long, most of the water that is blown further backward from the protruding portion 10 hardly adheres to the body that is blown forward. In particular, as shown in FIG. 7, for example, S ₁
Ice buildup gradually occurs from ~ _S3 , but since the protruding portion 10, which is the front end of this ice buildup, protrudes further from the body side inner wall 7, even if the ice buildup progresses, the air flow B The action of catching water does not decrease, and even if water is blown forward from the tip of the icing at the position of the protrusion 10, the distance from the inner wall 7 on the body side is increased, so the water does not adhere to the body side. will be further reduced.

Therefore, even if icing occurs in the rear wheel house 2 with the protrusion 10 formed thereon, as shown in FIG. , there is almost no icing on other parts.

In the embodiment shown in FIG. 5, a protrusion 10 is provided on the inner wall of the body.
It may be any vertically protruding portion that protrudes outward from the body-side inner wall 7, and its configuration is not limited to the embodiment.

Therefore, as shown in FIG. 9, the protrusion 10 is
Panels 7A and 7B forming the body side inner wall 7
It may also be formed by protruding an extension of and joining its ends.

In addition, as shown in FIG. 10, in addition to the protrusion 10, a guide plate 10A is formed at the rear of the protrusion 10, and this part further drains the water that has fallen along the protrusion 10. It can lead you backwards.

FIG. 11 is a perspective view showing an embodiment in which the present invention is applied to a front wheel house 3.

Inside the front wheel house 3, the main air flow occurs from the front of the vehicle to the rear, and
The water that enters the front wheel house 3 is the water splashed upward and forward by the front wheel 5, so the protruding portion 10
It is formed in the vertical direction on the body side inner wall 9 forward of the center.

In this embodiment, as in the embodiments shown in FIGS. 5 to 10, icing occurs only on the upstream side of the protrusion 10 and a portion of the suspension component 8 (see FIG. 12). Therefore, icing rarely occurs in important parts. Further, even if no icing occurs, it is possible to prevent mud and the like from adhering to the body side inner wall 9 and the suspension parts 8.

In each of the above-mentioned embodiments, the protrusion 10 is formed in a substantially vertical direction, but this substantially causes separation of the air flow, and thereby causes air to flow downstream from the protrusion 10. Any structure may be used as long as it can prevent icing from occurring, and therefore, the protrusion 10 may be formed substantially in the vertical direction.

In particular, when the protruding part 10 is installed with the upper part inclined toward the upstream side of the air flow than the lower part, the air flow along the inner wall on the body side not only causes separation at the protruding part 10, but also causes separation toward the downstream side. Since it is deflected downward, there is an advantage that moisture adhesion and icing can be effectively suppressed.

Since the present invention is constructed as described above, it has the excellent effect of significantly reducing the formation of ice in the wheel house, thereby preventing the occurrence of abnormal noise and deterioration of riding comfort.
