Description

  The present invention relates to a rectifying structure for a vehicle including spats.

  In the front part structure of an automobile described in Patent Document 1 below, a tire deflector (spats) is arranged on the front side of the front wheel, and the tire deflector is attached to the bumper face at its attaching part. Moreover, the tire deflector has a main body portion, and the main body portion is formed in a plate shape and extends from the attachment portion to the vehicle lower side. As a result, when the vehicle travels, the traveling wind hits the main body portion, thereby preventing the traveling wind from directly hitting the front wheels.

JP 2007-168620 A German Patent Application No. 102010037616

  By the way, when the traveling wind hitting the main body portion is allowed to flow outward in the vehicle width direction, it is effective to flow the traveling wind toward the rear side of the vehicle along the outer surface in the vehicle width direction of the front wheels. In this case, for example, a guide portion that is inclined toward the rear side of the vehicle as it goes outward in the vehicle width direction is formed in the vehicle width direction outer side portion of the main body portion, and traveling wind is moved outward in the vehicle width direction by this guide portion. It is conceivable to flow.

  However, in order for the traveling wind to flow along the outer surface of the front wheel in the vehicle width direction, it is necessary to set a large inclination angle of the guide portion with respect to the main body portion (vehicle width direction) and to secure a certain length of the guide portion. is there. For this reason, the protrusion amount of the guide part protruded from the main body part to the vehicle rear side is increased, and the tip part (vehicle width direction outer side end part) of the guide part approaches the front wheel. Thereby, there is a possibility that the distance between the front end portion of the guide portion (the vehicle width direction outer side end portion) and the front wheel cannot be secured.

  Therefore, by changing the position of the main body part to the vehicle front side, the inclination angle of the guide part can be set large while ensuring the distance between the front end part of the guide part (vehicle width direction outer end part) and the front wheel, The length of the guide part can be secured. However, in this case, there is a problem that the distance between the main body portion and the front wheels becomes long, and the original function of the tire deflector for suppressing the direct contact of the traveling wind with the front wheels is deteriorated.

  In view of the above facts, an object of the present invention is to provide a vehicular rectifying structure that can enhance the rectifying function of the front wheels to the outside in the vehicle width direction without impairing the original function of spats.

  The vehicle rectifying structure according to claim 1 is provided with a spat that is provided on the front side of the front wheel and has a plate-like main body disposed with a plate thickness direction in the vehicle front-rear direction, and a vehicle width direction of the main body A shielding wall portion extending from the outer end portion toward the vehicle front side, and a guide portion extending from the front end portion of the shielding wall portion toward the vehicle width direction outer side and the vehicle rear side.

  In the vehicle rectifying structure according to the first aspect, the spats are provided on the vehicle front side of the front wheels. The spats have a plate-like main body, and the main body is arranged with the plate thickness direction in the vehicle front-rear direction. Thereby, since a part of traveling wind hits the main part of spats, it is suppressed that the traveling wind hits a front wheel directly.

  Here, the shielding wall extends from the end of the main body in the vehicle width direction to the vehicle front side, and the guide extends from the front end of the shielding wall to the vehicle width direction outside and the vehicle rear side. That is, the guide part which inclines to the vehicle rear side as it goes to the vehicle width direction outer side in planar view can be provided in the vehicle width direction outer side of a main-body part. Thereby, the driving | running | working wind which contacted the guide part can be flowed to the vehicle width direction outer side. And since the guide part is extended in the vehicle width direction outer side from the front-end part of a shielding wall part, the base end part (vehicle width direction inner side edge part) of a guide part is arrange | positioned rather than a main body part at the vehicle front side. Accordingly, the guide portion is configured to flow the traveling wind toward the vehicle rear side along the vehicle width direction outer side surface of the front wheel while ensuring the distance between the front end portion (vehicle width direction outer end portion) of the guide portion and the front wheel. The shape (inclination angle, length, etc.) can be set. Therefore, it is possible to set the guide portion that rectifies the traveling wind in the effective direction outside the vehicle width direction while maintaining the position of the main body portion in the vehicle front-rear direction.

  The rectifying structure for a vehicle described in claim 2 is the rectifying structure for a vehicle according to claim 1, wherein an inner side surface in the vehicle width direction of the shielding wall portion is directed outward in the vehicle width direction toward the vehicle front side in plan view. It is arranged at an angle.

  According to the rectifying structure for a vehicle described in claim 2, it is possible to reduce the air resistance due to the traveling wind as compared with a case where the inner side surface in the vehicle width direction of the shielding wall portion is arranged along the vehicle front-rear direction in plan view. . That is, the inner side surface of the shielding wall portion in the vehicle width direction is inclined outward in the vehicle width direction as it goes to the front side of the vehicle in plan view, so that the vehicle width of the front surface of the main body portion and the shielding wall portion is larger than in the above case. Air in a region intersecting with the inner side surface in the direction easily flows outward in the vehicle width direction. Thereby, since the pressure of this area | region is disperse | distributed, the pressure in the said area | region can be made low compared with said case. Therefore, the air resistance due to the traveling wind can be reduced.

  The vehicle rectifying structure according to claim 3 is the vehicle rectifying structure according to claim 1 or 2, wherein the inner side surface in the vehicle width direction of the shielding wall portion is directed toward the vehicle lower side in a front view. It is arranged to be inclined outward in the vehicle width direction.

  In the rectifying structure for a vehicle according to claim 3, the inner side surface in the vehicle width direction of the shielding wall portion is arranged to be inclined outward in the vehicle width direction toward the vehicle lower side in a front view. The traveling wind hitting the front surface easily flows from the lower end of the shielding wall portion to the outside in the vehicle width direction. Thereby, the air resistance by running wind can be further reduced.

  The vehicular rectifying structure described in claim 4 is the vehicular rectifying structure according to any one of claims 1 to 3, wherein an end of the guide portion on the outer side in the vehicle width direction is in the front wheel. It is arranged on the outer side in the vehicle width direction from the starting point of the corner on the outer side in the vehicle width direction.

  In the vehicular rectifying structure described in claim 4, since the end portion of the guide portion on the outer side in the vehicle width direction is disposed on the outer side in the vehicle width direction from the starting point of the corner portion on the outer side in the vehicle width direction of the front wheel. The traveling wind that has been peeled off flows mainly from the guide portion toward the outside in the vehicle width direction from the starting point of the corner portion of the front wheel. Thereby, the traveling wind peeled from the guide part can be efficiently flowed to the vehicle rear side along the vehicle width direction outer side surface of the front wheel.

  According to the rectifying structure for a vehicle according to the first aspect, the rectifying function of the front wheels to the outside in the vehicle width direction can be enhanced without impairing the original function of the spats.

  According to the rectifying structure for a vehicle according to claim 2, it is possible to reduce the air resistance due to the traveling wind.

  According to the rectifying structure for a vehicle according to the third aspect, the air resistance due to the traveling wind can be further reduced.

  According to the rectifying structure for a vehicle according to the fourth aspect, the traveling wind peeled off from the guide portion can be efficiently flowed to the vehicle rear side along the outer side surface in the vehicle width direction of the front wheel.

(First embodiment)

  The vehicle rectifying structure S1 according to the first embodiment will be described with reference to FIGS. In the drawings, the front side of the vehicle is indicated by an arrow FR, the inner side in the vehicle width direction is indicated by an arrow IN, and the upper side of the vehicle is indicated by an arrow UP. Further, since the front portion of the vehicle 10 to which the vehicle rectifying structure S1 is applied is configured to be bilaterally symmetric in the vehicle width direction, the vehicle right side portion in the front portion of the vehicle 10 will be described. Description of the left side portion of the vehicle will be omitted.

  As shown in FIG. 3, the vehicle 10 includes a front tire 12 as a front wheel, and the front tire 12 is disposed in a wheel house 14. An air spats 20 as spats is disposed on the front side of the front tire 12, and the air spats 20 are fixed to the under floor 16 of the vehicle 10. And the air spats 20 are comprised including the attachment wall part 22, the main body wall part 26 as a main-body part, the shielding wall part 28, and the guide wall part 30 as a guide part. Hereinafter, the configuration of the air spats 20 will be described.

  As shown in FIGS. 1 and 2, the mounting wall portion 22 is formed in a substantially rectangular plate shape, and is disposed with the plate thickness direction being the vehicle vertical direction. A plurality (three in this embodiment) of attachment holes 24 are formed in the attachment wall portion 22, and fastening members such as bolts 18 (see FIG. 3) are inserted into the attachment holes 24. The mounting wall portion 22 is fixed to the floor 16 by the bolt 18.

  The main body wall portion 26 is formed in a substantially rectangular plate shape, and protrudes from the rear end portion of the mounting wall portion 22 to the vehicle lower side with the plate thickness direction being the vehicle front-rear direction. Thereby, when the vehicle 10 travels, a part of the traveling wind flowing toward the rear side of the vehicle on the front side of the front tire 12 hits the front surface 26A of the main body wall portion 26, so that the traveling wind directly hits the front tire 12. The hit is suppressed.

  The shielding wall portion 28 is formed in a substantially rectangular plate shape, and protrudes from the vehicle width direction outer side end portion of the mounting wall portion 22 toward the vehicle lower side with the plate thickness direction being the vehicle width direction. It is coupled to the outer end in the vehicle width direction. In other words, the shielding wall portion 28 protrudes from the vehicle width direction outer side end portion of the main body wall portion 26 in the plan view to the vehicle front side, and the shielding wall portion 28 has a vehicle width direction inner side surface 28A and a vehicle width direction outer side surface 28B. However, it is arrange | positioned along the direction orthogonal to a vehicle width direction.

  The guide wall portion 30 extends from the front end portion of the shielding wall portion 28 to the vehicle width direction outer side and the vehicle rear side. Further, the guide wall portion 30 is curved so as to protrude obliquely forward and outward in the vehicle width direction in plan view. That is, the guide wall portion 30 is inclined in a curved shape toward the vehicle rear side as it goes outward in the vehicle width direction in plan view. As shown in FIG. 3, the front end portion (outer end portion in the vehicle width direction) of the guide wall portion 30 is disposed on the outer side in the vehicle width direction from the starting point A of the corner portion 12A on the outer side in the vehicle width direction of the front tire 12. In addition, the front tire 12 is disposed on the outer side in the vehicle width direction than the outer side surface 12B in the vehicle width direction. Further, the front end portion of the guide wall portion 30 is disposed on the rear side of the vehicle with respect to the main body wall portion 26, and the length of the guide wall portion 30 is set so as to rectify the traveling wind hitting the guide wall portion 30. ing. Furthermore, the inclination angle θ at the front end portion of the guide wall portion 30 is set so that the traveling wind hitting the guide wall portion 30 flows to the vehicle rear side along the vehicle width direction outer side surface 12B of the front tire 12 ( (See FIG. 2A). Here, the inclination angle θ refers to an angle formed between a tangent line B in contact with the vehicle width direction outer side end portion of the guide wall portion 30 and a reference line L along the vehicle width direction.

  Next, functions and effects in the first embodiment will be described.

  When the vehicle 10 having the vehicle rectifying structure S1 configured as described above travels, a part of the traveling wind F flowing under the vehicle below the floor 16 hits the front surface 26A of the main body wall portion 26 of the air spats 20 and travels. The wind F is peeled off from the lower end of the main body wall portion 26 and flows to the rear side of the vehicle (see arrow F in FIG. 1). As a result, the main body wall portion 26 prevents a part of the traveling wind F from directly hitting the front tire 12.

  The other part of the traveling wind F hits the guide wall 30 of the air spats 20, and the traveling wind F hitting the guide wall 30 flows along the guide wall 30 to the rear side of the vehicle. Then, the traveling wind F is peeled off at the front end portion of the guide wall portion 30, and the peeled traveling wind F flows toward the vehicle rear side along the vehicle width direction outer side surface 12B of the front tire 12 (arrow F in FIG. 3). reference). As a result, air turbulence in a region outside the front tire 12 in the vehicle width direction is suppressed, so that the traveling wind F is rectified in the effective direction by the guide wall portion 30.

  Here, the shielding wall portion 28 extends from the vehicle width direction outer side end portion of the main body wall portion 26 of the air spats 20 to the vehicle front side, and the guide wall portion 30 extends from the front end portion of the shielding wall portion 28 to the vehicle width direction outer side. It extends to the rear side. That is, the main body wall portion 26 is disposed so as to be inclined toward the rear side of the vehicle as it goes outward in the vehicle width direction in plan view. For this reason, as described above, the traveling wind F hitting the guide wall portion 30 can be rectified along the guide wall portion 30 outward in the vehicle width direction. In addition, since the guide wall portion 30 extends outward from the front end portion of the shielding wall portion 28 in the vehicle width direction, the base end portion (vehicle width direction inner end portion) of the guide wall portion 30 is on the vehicle front side relative to the main body wall portion 26. Placed in. Thus, the traveling wind F is moved along the vehicle width direction outer side surface 12B of the front tire 12 while ensuring the distance between the front end portion (vehicle width direction outer end portion) of the guide wall portion 30 and the front tire 12. The shape of the guide wall portion 30 (the inclination angle θ and the length of the guide wall portion 30) can be set so as to flow to the rear side. Therefore, it is possible to set the guide wall portion 30 that rectifies the traveling wind F in an effective direction outside the vehicle width direction while maintaining the position of the main body wall portion 26 in the vehicle front-rear direction (without moving to the vehicle front side). Thus, the original function of the spats 20 is not hindered, and the function of rectifying the front tire 12 to the outside in the vehicle width direction can be enhanced.

  Further, the front end portion (outer end portion in the vehicle width direction) of the guide wall portion 30 is disposed on the outer side in the vehicle width direction from the starting point A of the corner portion 12A on the outer side in the vehicle width direction of the front tire 12. For this reason, the traveling wind F peeled off from the guide wall portion 30 mainly flows from the guide wall portion 30 to the outside in the vehicle width direction from the starting point A of the corner portion 12A of the front tire 12. Thereby, the traveling wind F peeled off from the guide wall part 30 can be efficiently flowed to the vehicle rear side along the vehicle width direction outer side surface 12B of the front tire 12.
