Description

  The present invention relates to a deflector device.

  When the vehicle body roof is opened in an open state, wind is caught from the opening or wind noise is generated.

Therefore, conventionally, there is known a technology for providing a baffle plate at the edge of the opening of the roof to suppress the entrainment of wind (hereinafter referred to as a crosswind) flowing along the vehicle body roof from the side of the vehicle and the generation of wind noise. (For example, refer to Patent Document 1).
JP 2001-180285 A

  However, in the technique described in the above-mentioned document, when the opening is opened, the shielding members that prevent the entrainment of the cross wind are erected substantially vertically on both the left and right sides of the opening. Therefore, when the lid is fully opened, Air resistance increases due to the presence, and wind winds and wind slops (low-frequency sound generated by air column vibrations in the passenger compartment due to wind entanglement in the passenger compartment) are generated because the cross wind winds over the shielding member. There is a problem to do.

  Therefore, an object of the present invention is to provide a deflector device that can suppress the generation of wind noise and wind slop due to cross winds when the opening of a roof is opened.

  The present invention has been made in view of the above circumstances, and is a deflector device that includes a side deflector that rectifies an airflow that flows along the vehicle body roof from the side of the vehicle when the opening is opened, and the side deflector is It is a deflector device whose main feature is that it is tilted toward the opening when standing.

  When the opening is opened while the vehicle is running, the side deflector stands and suppresses the side wind. At this time, since the side deflector is inclined toward the opening, the air resistance is smaller than that in which the side deflector is erected vertically, and a rectifying effect that blows the cross wind farther can be obtained. , It is possible to suppress the cross wind from being wound around the opening. Thereby, compared with what made the side deflector stand upright, generation | occurrence | production of a wind noise and generation | occurrence | production of a wind slop can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The link member 45 has an end on the vehicle front side connected to a bracket 41c formed integrally with the deflector body 41 via a ball joint 45b, while an end on the vehicle rear side connects the ball joint 45c. And is connected to the slider 46.

  The slider 46 is supported by a rail 21a (see FIG. 5) formed on the unit frame 21 so as to be slidable in the vehicle front-rear direction. The rail 21a is provided with a stopper, and the slider 46 slides forward of the vehicle. Is regulated at a predetermined position.

  Therefore, when the lid 2 is tilted up and further moved to the rear of the vehicle until the opening 12 is fully opened, the deflector body 41 is turned upright and the link member 45 is lifted upward, and the vehicle rear side end portion Moves together with the slider 46 to the front of the vehicle. When the slider 46 slides on the rail 21a to the foremost position, the turning of the deflector body 41 to the upper side of the vehicle is restricted.

  Therefore, the maximum standing angle of the deflector body 41 at the time of standing is determined by adjusting the sliding amount of the slider 46 forward of the vehicle. In the first embodiment, this angle is set to be inclined toward the opening 12 as shown in FIG.

  Here, the deflector body 41 is shown in FIG. 9 in any of the half-upright state of the deflector body 41 shown in FIG. 3B and the upright state of the deflector body 41 as shown in FIG. As shown, the width and arrangement of the roller 23 are set so as to overlap the movement locus a of the roller 23 in the vehicle front-rear direction.

  Further, as shown in FIG. 6, the corner member 42 is tilted and raised as the above-described deflector main body 41 rises. The corner member 42 rotates in the vertical direction of the vehicle with the rotation of the deflector body 41. When the lid 2 and the front deflector 3 are closed, the vehicle of the front deflector 3 is shown in FIG. It is arranged overlapping the lower side. Then, when the side deflector 4 is erected after the front deflector 3 is erected, the corner member 42 is in the erected state shown in FIG. 6 while sliding the tip 42a thereof against the back surface 3b of the front deflector 3. Take. In this standing state, as shown in FIGS. 6 and 7, the tip end portion 42 a of the corner member 42 abuts against the back surface of the front deflector 3 and closes the gap between the front deflector 3 and the deflector body 41. .

  Further, in this standing state, the corner member 42 is formed in an arc shape that smoothly continues from the upper end 3a of the front deflector 3 to the upper end 41b of the deflector body 41, as shown in FIG.

  Next, the operation of the deflector device according to the first embodiment will be described.

  When the opening 12 shown in FIG. 3A is closed, the side deflector 4 is lying on the vehicle lower side of the lid 2 and the front deflector 3. At this time, the side deflector body 41 is urged to rotate in the upright direction by the coil spring 44, but the deflector body 41 is pressed by the roller 23 provided on the back surface of the lid 2 as shown in FIG. As a result, the side deflector 4 is maintained in a lying state.

  Next, when the lid 2 is slid to the rear of the vehicle, the lid 2 is tilted up as shown in FIG. 3 (b) to bring the opening 12 into a half-open state, and the front deflector 3 stands up in conjunction with this. To do.

  Further, as the position of the roller 23 rises as the lid 2 is tilted up, the deflector body 41 is raised by the urging force of the coil spring 44, the link member 45 is pulled upward, and the rear end of the vehicle is The slider 46 moves forward with the vehicle. At this time, the rotation of the deflector body 41 in the standing direction is regulated by the roller 23 in the middle thereof, and is in a semi-standing state.

  Then, when the lid 2 is moved rearward from the tilt-up state of FIG. 3B until the opening 12 is fully opened as shown in FIG. 3C, the roller 23 on the back surface of the lid 2 is moved along the way. , Away from the upper surface 41a of the deflector body 41. Then, the slider 46 moves on the rail 21a to the foremost position, and the rotation of the deflector body 41 is restricted. As a result, the deflector body 41 is completely upright.

  Further, the corner member 42 stands up together with the deflector body 41. At this time, the corner member 42 stands up while its front end 42a slides against the back surface 3b of the front deflector 3, and is shown in FIGS. As described above, the gap between the front deflector 3 and the deflector body 41 is closed. Further, at this time, the corner member 42 smoothly connects the upper end 3 a of the front deflector 3 and the upper end 41 b of the deflector body 41.

  In the state where the side deflector 4 is erected in this way, the deflector body 41 is inclined toward the opening 12, so that the side wind is opened by the deflector body 41 as shown in FIG. As shown in FIG. 5A, the wind is not easily involved as in the case where the deflector main body 41 is upright as shown in FIG.

  Therefore, the air resistance by the deflector body 41 is reduced, and the side wind is prevented from being caught in the opening 12, and the generation of wind noise and wind slop due to the side wind can be suppressed.

  Furthermore, since the deflector body 41 is formed of a highly rigid plate made of metal, hard resin, or the like, flutter is suppressed, and generation of vibration noise due to the flutter can be suppressed.

  Further, when the side deflector 4 stands, the gap between the deflector body 41 and the front deflector 3 is closed by the corner member 42 as shown in FIGS. 6 and 7, so that wind flows from this gap. The generation of wind noise and wind slop due to this inflow can be suppressed.

  Further, in the side deflector 4, the height of the deflector body 41 is formed lower than that of the front deflector 3. Therefore, the deflector body 41 does not receive wind directly from the front of the vehicle, and the generation of wind noise due to this can be suppressed.

  In addition, since the corner member 42 smoothly connects the upper end 3a of the front deflector 3 and the upper end 41b of the deflector body 41, the turbulence of the airflow can be suppressed in this portion. The generation of wind noise can be suppressed.

  Next, when closing the opening 12, the lid 2 is slid forward of the vehicle. At this time, the roller 23 comes into contact with the upper surface 45a of the link member 45, and the link member 45 is pushed downward by the component force of the input from the roller 23 to the vehicle lower side. Further, the link member 45 is laid down while moving the slider 46 rearward of the vehicle, and the deflector body 41 is laid down. Then, when the deflector body 41 falls down to the semi-standing state shown in FIG. 3B, the roller 23 rides on the deflector body 41 from the link member 45, moves on the upper surface 41a of the deflector body 41, and the deflector body 41 , Maintained in a semi-standing position.

  Thereafter, when the lid 2 is tilted down, the roller 23 pushes the deflector body 41 downward in the vehicle, and the deflector body 41 rotates to the lying down position shown in FIG. Further, the front deflector 3 also lies down in conjunction with the movement of the lid 2 to the fully closed position, and as shown in FIG. 3A, the opening 12 is closed in the fully closed state by the lid 2 and the front deflector 3. It becomes.

  As mentioned above, although embodiment and Example 1 of this invention were explained in full detail with reference to drawings, specific structure is not restricted to this Embodiment and Example 1, and does not deviate from the summary of this invention. A degree of design change is included in the present invention.

  That is, in the first embodiment, the outer slide type in which the lid 2 slides outside the vehicle of the roof 11 is shown, but other types such as an inner slide type in which the lid 2 slides on the side of the cabin 13 of the roof 11 are used. It can also be applied to.

  In addition, the width of the deflector body 41, the height at the time of standing, and the inclination angle toward the opening 12 may be arbitrarily set according to the dimension in the vehicle width direction of the opening 12, as shown in the first embodiment. It is not limited. That is, if the dimension of the opening 12 in the vehicle width direction is increased, it is preferable to set the height of the deflector body 41 when standing and to set the inclination angle large.

  In the first embodiment, the example in which the side deflector 4 is laid down by the roller 23 and the link member 45 provided on the lid 2 has been described. However, a mechanism that interlocks with the movement of the slider 22b that slides the lid 2 is provided. Alternatively, an independent driving means may be provided.
