  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. In the following plurality of embodiments, a deflector structure is applied to the front wheel of an automobile as a vehicle. Note that similar components are included in the following embodiments. Therefore, common reference numerals are given to those similar components, and redundant description is omitted. In each figure, the state in which the fender panel is removed and the deflector structure is exposed is shown. In the figure, FR indicates the front of the vehicle, UP indicates the upper side of the vehicle, and WO indicates the outer side in the vehicle width direction. Yes.

  (First Embodiment) FIGS. 1 to 5 show a deflector structure according to a first embodiment of the present invention.

  In the deflector structure according to the present embodiment, as shown in FIG. 1, a plate-like deflector 2 is provided in front of the wheel Wh with a space therebetween. The deflector 2 is attached to the lower end portion of the front wall portion 3a of the wheel house 3 that covers at least the outer peripheral side and the upper side of the wheel Wh with a space therebetween so as to intersect (substantially orthogonal) the vehicle longitudinal direction. Yes. Further, a plate-like protector 4 is provided at the lower end of the front wall portion 3a so as to be pointed in a substantially triangular shape toward the front of the vehicle in plan view. The protector 4 is arranged in a substantially horizontal posture, and forms a part of the bottom wall portion of a front compartment Fc (see FIG. 3 and the like) that is formed in the front portion of the vehicle and accommodates a vehicle driving engine, a motor, and the like. is doing. In the present embodiment, the wheel house 3 and the protector 4 are configured as an integral part, and the deflector 2 as another part is attached to the lower surface of the protector 4.

  Further, as shown in FIG. 2, the corners on the outer side and the lower side of the deflector 2 in the vehicle width direction are chamfered. In the front view of FIG. 2, the deflector 2 is located below the protector 4 and mainly the vehicle of the wheel Wh. It covers the inner side in the width direction.

  About this deflector 2, it is necessary to ensure the rigidity of the grade which does not deform | transform according to the wind pressure of the driving | running | working wind S, etc. In the present embodiment, as shown in FIGS. 1, 4, etc., a plurality of protruding wall portions 6 (three in this embodiment) are provided on the rear surface 2 b of the deflector 2, and the rigidity is improved by these protruding wall portions 6. is doing.

  Moreover, in this embodiment, the air flow generation mechanism 1 which produces the air flow A which goes to the outer side of the said deflector 2 along the deflector 2 is provided. In the present embodiment, as the air flow generation mechanism 1, an air passage 5 is formed in which the air in the front compartment Fc flows out into the space between the deflector 2 and the wheel Wh to form the air flow A.

  Specifically, as shown in FIG. 3, a slit is formed along the lower edge of the front wall 3 a of the wheel house 3 in the protector 4 constituting a part of the bottom wall (outer wall) of the front compartment Fc. A plurality of through-holes 5a are formed side by side, and the air in the front compartment Fc is discharged to the outside of the vehicle, that is, the lower surface side of the protector 4 through these through-holes 5a, and the air flow A is generated by the flow of the discharged air. Forming. That is, in the present embodiment, these through holes 5 a correspond to the air passage 5.

  The air passage 5 passes through the bottom wall portion (the protector 4 in the present embodiment) or the rear wall portion (the front wall portion 3a of the wheel house 3 in the present embodiment) of the front compartment Fc, inside and outside the vehicle, in the present embodiment. This is a passage communicating between the inside and outside of the front compartment Fc. When the vehicle travels, the air inside the vehicle, that is, the air in the front compartment Fc is sucked out through the air passage 5 by the negative pressure of the air flowing outside the vehicle and the air flowing inside the wheel house 3. That is, in the present embodiment, the air flow generation mechanism 1 that generates the air flow A can be obtained as a relatively simple configuration by forming the air passage 5.

  Further, as shown in FIG. 1, in the present embodiment, the through hole 5 a is opened behind the deflector 2. Since the pressure behind the deflector 2 tends to be lower than that at the front, it is easy to obtain a suction effect through the air passage 5.

  Further, the through hole 5 a is opened along the upper end edge of the rear surface 2 b of the deflector 2. Therefore, the air flow A becomes a flow along the rear surface 2 b of the deflector 2. At this time, as described above, since the projecting wall portion 6 is formed on the rear surface 2 b of the deflector 2, the air flow A is guided along the projecting wall portion 6. That is, in the present embodiment, the protruding wall portion 6 corresponds to the guide portion.

  The protruding wall portion 6 has a substantially constant width and height, and, as shown in FIG. 4, the upper side on the inner side in the vehicle width direction (upper right side in FIG. 6) and the lower side on the outer side in the vehicle width direction (lower left side in FIG. 6). ). The plurality of protruding wall portions 6 are arranged substantially parallel to each other, and the through holes 5 a are arranged so as to face the upper portions of the protruding wall portions 6. Accordingly, the air flow A flowing out of the through hole 5a is directed obliquely downward from the upper side in the vehicle width direction to the lower side in the vehicle width direction while being guided by the rear surface 2b and the protruding wall portion 6 of the deflector 2, and the deflector 2 This flows out from the outer edge 2a to the outer side (in this embodiment, outward and downward in the vehicle width direction, diagonally downward in FIG. 4).

  By the air flow A thus formed, the traveling wind S is diverted to the outside of the deflector 2 (outside of the vehicle) as shown in FIG. 5B. In addition, as shown in FIG. 2, the airflow A is blown from the deflector 2 toward the side where the wheel Wh is exposed in the front view, so that the traveling wind S is on the front side of the airflow A, that is, outside the vehicle width direction. It will be deflected toward the lower side (lower right side in FIG. 2). Therefore, compared with the case where the air flow A is not formed (FIG. 5A), the pressure based on the traveling wind S is reduced by reducing the pressure on the front surface of the wheel Wh (front side of FIG. 2, lower side of FIG. 5). Resistance can be reduced.

  As described above, in the present embodiment, the air flow generating mechanism 1 that generates the air flow A that flows substantially along the deflector 2 and toward the outside of the deflector 2 is provided. Therefore, the traveling wind S can be diverted to the outside of the deflector 2 by the air flow A, so that the effect of reducing the air resistance by the deflector 2 can be further increased compared to the case where the air flow A is not formed.

  Further, in the present embodiment, the air flow generating mechanism 1 uses the pressure difference between the inside and outside of the vehicle caused by the running of the vehicle to cause the air inside the vehicle to flow out of the vehicle via the air passage 5 communicating between the inside and outside of the vehicle. Configured to let you. Therefore, the airflow generation mechanism 1 can be obtained with a relatively simple configuration.

  In the present embodiment, the air flow generation mechanism 1 is configured to allow the air in the front compartment Fc to flow out of the front compartment Fc. That is, since the air inside the front compartment Fc is sucked out through the air passage 5 by using the negative pressure outside the front compartment Fc that is generated during traveling, this can be used as the air flow A. 1 can be obtained as a relatively simple configuration. Moreover, there exists an advantage that it is easy to apply to the front wheel (wheel Wh) of a vehicle.

  In the present embodiment, the through hole 5 a is formed in the protector 4 that forms the bottom wall (outer wall) of the front compartment Fc, and this is used as the air passage 5. Therefore, the air passage 5 can be formed relatively easily, and as a result, the air flow generation mechanism 1 can be obtained with a relatively simple configuration.

  In the present embodiment, the projecting wall portion 6 as a guide portion for guiding the airflow A is provided on the rear surface 2 b as the surface of the deflector 2. Therefore, the air flow A can be caused to flow in a more suitable direction by the protruding wall portion 6 as the guide portion, and the air resistance reduction effect by the air flow A can be obtained more effectively. There is an advantage that the rigidity of the deflector 2 can be increased, the body portion of the deflector 2 can be thinned to promote weight reduction, and vibration can be suppressed.

  (Second Embodiment) FIGS. 6 and 7 show a second embodiment of the present invention. Also in this embodiment, the air in the front compartment Fc is caused to flow out of the front compartment Fc through the air passage 5 to form the air flow A substantially along the deflector 2 having the protruding wall portion 6 in the first embodiment. It is the same as the form.

  However, in the air flow generation mechanism 1 </ b> A according to the present embodiment, the point that the shielding portion 7 that suppresses the entry of foreign matters (such as mud, stones, water, and dust) into the upstream side of the air passage 5 is provided. This is different from the first embodiment.
