Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an undercover for an automobile, which is arranged along a lower surface of a front body.

(Prior Art) The force (aerodynamic force) that an automobile receives from air increases in proportion to the speed at which it runs. Therefore, it is important to eliminate this air resistance as the speed increases. Therefore, today, as a method of reducing air resistance, an under cover is attached along the lower surface of the front body where the engine room is provided.

FIG. 4 schematically shows an example of a conventional automobile equipped with the under cover, and FIG.
It is a principal part expanded sectional view of the vehicle shown in the figure.

In FIGS. 4 and 5, a bumper 32 is provided on the front surface of the front body 31 in which the engine room of the automobile is provided.
And the bumper facer attached to the lower side of this bumper 32
33 etc. are provided. An under cover 35 is provided below the front body 31 and extends from the bumper fascia 33 toward the rear portion of the vehicle body so as to extend along the lower surface of the center member 34, that is, the lower surface of the front body 31. .

The under cover 35, as shown as a single body in FIG. 6, is used when the jack up is performed.
The garage jack 36 is provided at a portion corresponding to the garage jack receiving surface 37 of the center member 34 to which the garage jack 36 (see FIG. 5) is applied.
A notch portion 38 is provided for escaping. Depending on the undercover, holes may be formed instead of the notches 38.

(Problems to be solved by the invention) However, the notch 38 provided in the portion corresponding to the garage jack receiving surface 37 is not used for other purposes except when the garage jack 36 is used. From the viewpoint of air rectification, the air flow is adversely affected when traveling, which adversely affects the air flow.

The present invention has been made in view of the above problems,
Its purpose is to provide an undercover for automobiles that does not need to be provided with notches or holes in the part corresponding to the garage jack receiving surface that disturbs the air flow under the floor, and improves the rectification under the floor. is there.

(Means for Solving the Problems) In order to achieve the above object, the undercover of an automobile according to the present invention is formed of a resin material and surrounds the outside of a portion corresponding to the garage jack receiving surface of the front body. A thin portion for bending is provided.

(Operation) According to this structure, the thin portion for bending is bent more easily than other portions. Therefore, when the garage jack is applied to the inner portion surrounded by the thin portion, the thin portion is bent. Then, the inner portion comes into contact with the garage jack receiving surface, and the garage jack comes into contact with the garage jack receiving surface through the inner portion. Therefore, it is possible to eliminate a notch or a hole formed in a portion corresponding to the garage jack receiving surface and disturbing air rectification under the floor.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

1 and 2 show a main part of an automobile to which an undercover according to an embodiment of the present invention is applied.
The parts shown in FIGS. 1 and 2 correspond to the parts shown in FIG. 5, and those denoted by the same reference numerals as those in FIG. 5 are the same as those in FIG. .

In FIGS. 1 and 2, the under cover 1 is
Provided below the front body (not shown) of the automobile, from the bumper fascia 33 toward the rear of the vehicle body along the lower surface of the center bumper 34, that is, the lower surface of the front body, and fixed by a fixing member (not shown). Has been. Further, the under cover 1 is formed of a resin material in a substantially dish shape.

Further, as shown in FIG. 3 as a single unit, the under cover 1 is used when jacking up the garage jack.
Garage jack receiving surface of center member 34 to which 36 is applied
A thin portion 3 and 4 for bending is provided in a portion 2 corresponding to 37 so as to surround the outer portion of the portion 2 so as to be thinner than other portions so as to be easily bent in the vertical direction in a double-circled state. ing. In addition, the corner portion 37a of the garage jack receiving surface 37 and the portion 2a with which the garage jack 36 abuts are thickened to reinforce them to prevent damage.

In an automobile using the undercover 1 configured as above, when jacking up, the garage jack 36 is applied from below the portion 2 of the undercover 1. Then, the thin parts 3 and 4 for bending the undercover 1
While the respective parts are being bent, the entire part 2 is pressed against the garage jack receiving surface 37 by the garage jack 36 to be in a close contact state, and the vehicle body is lifted.

Therefore, in this under cover 1, the garage jack 36 is applied to the garage jack receiving surface 37 via the part 2 without providing a hole or a notch that disturbs air rectification under the floor in the part to which the garage jack 36 is applied. Since it can be used as an air conditioner, air rectification can be improved.

The portion 2 of the undercover 1 may be in contact with the garage jack receiving surface 37 from the beginning or may be separated from it.

(Effects of the Invention) As described above, the automobile undercover according to the present invention eliminates the notch or hole formed in the portion corresponding to the garage jack receiving surface that disturbs air rectification under the floor. Therefore, it is possible to improve air rectification under the floor. In addition, by using this undercover, it is possible to expect a vehicle with good fuel economy and excellent economy.
