Abstract

PROBLEM TO BE SOLVED: To provide an under cover for a vehicle which rectifies a side wind and a wind hitting tires into a smooth air flow, and improves the maintenance efficiency and the visibility. SOLUTION: As an under cover 1 for vehicle, a side cover 2 extending from both sides of the load-carrying platform 11 of a vehicle to the lower side continuously; and a frame cover 3 to cover the platform 11 of the vehicle continued to the side cover 2 and bent in a curved surface form to both sides; are provided. And a tire cover 4 is formed in the tunnel form at the tire 13 position of the frame cover 3, and air rectifiers 5 are formed at the front side and the rear side of the tire cover 4. Furthermore, cuttings are formed in order to use function parts for maintenance, on the side cover 2 or on the frame cover 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a vehicle undercover that covers a lower portion of a bed of a vehicle such as a truck.

[0002]

2. Description of the Related Art Normally, a wide gap is formed in the lower portions of both sides of the bed of a vehicle such as a truck, but both side surfaces of the bottom of the bed may be covered with side skirts. This side skirt is specifically as shown in FIGS. 4 and 5.

As shown in the figure, the side skirt 21 is in the form of a flat plate, and hangs down so as to cover both side surfaces of the lower part of the luggage carrier 11.

The side skirt 21 covers and protects the side surface of the lower portion of the loading platform 11 such as a truck that tends to have a wide gap, and rectifies the air flow on the side surface of the lower loading platform 11.

[0005]

However, such a side skirt 21 does not have a rectifying action against the wind hit from the lateral direction and is easily affected by the lateral wind, so that the side skirt 21 does not move in the lateral direction during traveling. There was a risk of rolling of the car body when a strong wind blew.

Further, the side skirt 21 is used for the cargo bed 11
It is not possible to expect a rectification effect that only reduces the side surface of the lower part and reduces the air resistance when the running wind hits the tire.

Further, since the side skirt 21 hangs down close to the ground and completely hides the functional parts such as the fuel tank, it becomes an obstacle during maintenance.

Further, as shown by the broken line in FIG. 4, the side skirt 21 increases the visible side surface area, and the body looks like it hangs near the ground. Also gives a sense of weight.

The present invention focuses on such problems,
It is an object of the present invention to provide a vehicle undercover that straightens side winds and traveling winds hitting tires into a smooth flow and improves maintainability and visibility.

[0010]

According to a first aspect of the present invention, in an undercover for a vehicle, a side cover portion continuously extending downward from both side surfaces of a cargo bed of the vehicle and a vehicle connected to the side cover portion are provided. And a frame cover portion that covers the lower surface of the cargo bed toward both sides in a curved shape.

In the second aspect of the invention, the tire cover portion is formed in a tunnel shape at the tire position of the frame cover portion, and the air rectifying portions are formed before and after the tire cover portion.

In the third invention, the side cover portion or the frame cover portion is provided with a cutout portion for servicing the functional component.

[0013]

In the first aspect of the invention, the side cover portion rectifies the air flow on the side surface of the luggage carrier, and the frame cover portion on the lower surface of the luggage carrier curved in a curved shape releases the side wind to the vehicle body downward and rectifies it.

According to the second aspect of the invention, the air rectifying section releases the traveling wind hitting the tire downward to rectify it.

In the third aspect of the present invention, the portion required for the maintenance of the functional component is exposed from the notch, which contributes to the maintenance of the vehicle.

[0016]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the under cover 1 is attached so as to cover the bottom surface and the bottom surface of the luggage carrier 11 of the vehicle body.

The undercover 1 is composed of a side cover portion 2 and a frame cover portion 3. The side cover portion 2 is continuously extended downward from the side surface of the luggage carrier 11 and is further continuous from the side cover portions 2 on the left and right side surfaces. Then, as shown in FIG. 3, the frame cover portion 3 that covers the frame 12 on the lower surface of the luggage carrier 11 is formed. The frame cover portion 3 has a curved shape toward both sides like a ship bottom to cover the lower portion of the vehicle body in order to have a rectifying action against a side wind.

At the position of the tire 13 of the under cover 1, a tire cover portion 4 is formed so as to cover the tire 13. Before and after the tire cover portion 4, the tire 1
In order to rectify the traveling wind that hits the air conditioning unit 3, an air rectification unit 5 that is curved is formed.

Here, the tire cover portion 3 is designed to cover only the tire width W in a tunnel shape, and an opening portion 6 is formed in the middle portion thereof, and a suspension component (not shown), a differential gear box and the like are covered with a frame cover. It does not interfere with the part 3.

Further, the side cover portion 2 or the frame cover portion 3 of the under cover 1 is formed with a cutout portion 7 for partially exposing the functional component 14 such as a battery and a fuel tank for maintenance.

Next, the operation will be described.

First, as shown in FIG. 3, the frame cover portion 3 has its curved curved surface shape to smoothly rectify the lateral wind indicated by the arrow in the drawing downward along the curved surface.
As a result, the resistance due to the side wind is alleviated, and rolling or the like during traveling is prevented.

On the other hand, the running wind that hits the tire from the front is
As indicated by the arrow in FIG. 2, the air is rectified by the air rectification unit 5, and the air resistance during traveling is significantly reduced.
Further, at this time, although the cutout portion 7 is provided in the middle of the tire cover portion 4, since the traveling wind is released downward by the front and rear air rectifying portions 5, the suspension parts and the like exposed from the cutout portion 7 are not allowed to travel. It does not give resistance.

Also, since the main parts of the group of functional parts 14 mounted on the lower part of the cargo bed are completely covered by the under cover 1, the appearance is improved and the functional parts 14 are prevented from being soiled, while the cutouts 7 are formed. Due to the presence of the above, the parts necessary for the maintenance of the functional component group 14 are exposed, so that no problem occurs during the maintenance.

Further, since the frame cover portion 3 has a curved shape, the under cover 1 hangs near the ground when viewed from the side, as shown by the broken line in FIG. Since it does not look like, it does not give a heavy feeling visually.

[0027]

According to the first aspect of the present invention, since the frame cover portion curved in a curved shape allows the side wind to the vehicle body to escape downward and rectify the side wind, the resistance due to the side wind hitting the under cover is mitigated, and the rolling motion during running is prevented. It can be prevented. Further, because the frame cover portion is curved, the under cover does not appear to hang down close to the ground, so that a visual feeling of weight is alleviated. Furthermore, since the functional component group at the lower part of the loading platform is covered by the frame cover, dirt is prevented, and the overall appearance is improved.

According to the second aspect of the present invention, the air rectifying portion releases and rectifies the traveling wind that hits the tire downward, so that the traveling wind that hits the tire does not hinder traveling.

In the third aspect of the invention, the main part of the functional parts group is covered by the frame cover part, while the part necessary for the maintenance of the functional parts is exposed from the cutout part. Can be easily maintained.
