Description

  The present invention relates to a vehicle sunroof device deflector (hereinafter simply referred to as a “deflector”), and more particularly to a deflector including a blade that moves up and down along a front edge of an opening formed in a fixed roof of a vehicle.

  In a vehicle with a sunroof in which an opening is provided in a fixed roof of the vehicle, an unpleasant vibration sound having a low frequency called a wind slob is generated when the vehicle is driven with the opening being opened. FIG. 5 is an explanatory diagram of this wind slob generator. As shown in FIG. 5, when traveling with the opening 32 provided in the fixed roof 31 of the vehicle 30 with a sunroof being opened, the airflow 33 entering from the front or the airflow 34 entering from the side toward the opening 32 is It interferes with the airflow 35 sucked out from. As a result, periodic pressure fluctuations occur behind the opening surface, and these resonate to generate wind slob. In particular, at 32a and 32b in the vicinity of the corner on the rear side of the opening 32, the airflow 33 entering from the front and the airflow 34 entering from the side overlap, and interfere with the airflow 35 sucked from the room. Slobes are noticeable.

In order to suppress the occurrence of the wind slob, for example, a deflector including a blade that moves up and down along the front edge of the opening 32 as described in Patent Document 1 is used.
One end of the blade is supported by the other end of an arm pivotally attached to the inner frame, and the arm is constantly elastically biased upward by spring means such as a leaf spring. Thus, when fully closed, that is, when the slide roof is mounted on the opening 32, the blade is stored below the slide roof by sliding the arm downward with the slide roof. When the roof moves rearward, the arm released from the restriction by the lower surface of the slide roof rises due to the elastic force of the spring means, and the blade stands along the front edge of the opening 32.

  When this deflector is used, the airflow 33 entering from the front is changed to an upward airflow by the blade, so that interference with the airflow 35 sucked out from the room can be prevented and the occurrence of wind slob can be suppressed.

  On the other hand, the vehicle sunroof device is a so-called tilt-and-outer slide sunroof device (hereinafter simply referred to as “opening”) in which the slide roof is moved up to the rear of the fixed roof while the slide roof is tilted up. "Outer slide sunroof device"). FIG. 6 is a schematic perspective view of the sunroof device 36 of this type when fully opened. As shown in FIG. 6, the sunroof device 36 has a slide roof 39 that is attached to an opening 38 formed in a fixed roof 37 of the vehicle. A support portion (not shown) is fixed to the lower side portion of the slide roof 39, and the support portion moves rearward on a guide rail (not shown) provided on the inner frame. The slide roof 39 moves to the rear of the fixed roof 37, and the opening 38 is opened.

This outer slide sunroof device is fully open compared to the inner slide sunroof device that moves the slide roof 39 to the lower surface of the fixed roof 37 because the support portion easily interferes with the rear edge of the opening 38 when fully opened. The opening amount of the opening at the time is small, and the above-described airflow interference is relatively difficult to occur.
Furthermore, the slide roof 39 is inclined obliquely upward from the front end 39a of the slide roof 39 toward the rear end 39b when fully opened. As a result, the airflow entering from the front flows upward along the slide roof 39, and interference with the airflow sucked out from the room is further less likely to occur, so that the occurrence of wind slob is suppressed to some extent. Therefore, in the conventional outer slide sunroof device, a deflector has been unnecessary.

  However, in recent years, in the outer slide sunroof device, in order to increase the opening amount of the opening 38, various devices have been devised, and it has become necessary to install a deflector as the opening amount increases. As one configuration for increasing the opening amount of the opening 38, a configuration as shown in FIG. 7 which is an enlarged view of the inner frame in the portion E of FIG.

  As shown in FIG. 7, the side frame 40 is provided with a guide rail 41 for guiding a support portion (not shown) fixed to the lower side portion of the slide roof 39 (see FIG. 6) in the front-rear direction. ing. The guide rail front end portion 41 a protrudes forward from the front outer edge portion 42 a of the front frame 42. As a result, the guide rail front end portion 41a is provided in front of the guide rail front end portion of the conventional sunroof device, so that the mounting position of the support portion with respect to the slide roof 39 can be provided in front thereof. it can. When the mounting position of the support portion moves forward, the distance that the support portion can move before it interferes with the rear edge of the opening portion 38, that is, the movable stroke of the support portion becomes long. Can be increased. However, as the amount of opening increases, interference between the airflow flowing through the opening surface and the airflow sucked out from the room tends to occur.

On the other hand, as described in Patent Document 2, the conventional deflector is provided with a blade housing groove in the inner frame when fully closed, but the guide rail 41 as described above is extended forward. When the configuration is used, the guide rail 41 is in the way, and a storage groove cannot be provided in a portion where the side frame 40 and the front frame 42 overlap (hereinafter simply referred to as “corner portion”).
Japanese Utility Model Publication No. 3-52229 (first page, FIGS. 2 and 3) JP 2000-335248 A (paragraphs 0022 to 0023, FIG. 1)

  Therefore, although a configuration using a blade from which a portion to be installed in the corner portion is removed is considered, if the blade is not installed in the corner portion, in FIG. 5, an airflow 33 entering from the front and an airflow 34 entering from the side, It is difficult to suppress the occurrence of wind slobes at 32a and 32b where strong interference with the airflow 35 sucked out from the room occurs.

  The present invention has been made in view of such a problem, and it is possible to provide a blade even when there is no space for providing a storage groove in a corner portion, as in the case where a guide rail is extended forward. It is an object to provide a deflector that can be used.

The deflector according to claim 1 of the present invention that has solved the above problems includes a slide roof that is attached to an opening of a fixed roof of a vehicle, a side frame that extends in the vehicle front-rear direction, and a vehicle width direction. An inner frame that extends around the opening, and is provided on the side frame such that a front end protrudes forward from a front outer edge of the front frame, a guide rail for guiding the sliding roof in the longitudinal direction of the vehicle, a sunroof device provided with a front blade moves up and down along the front edge of the opening formed in the fixed roof of the vehicle, the side end portion of the front blade on the outside of, separate from the front blade, and the open corner blades, wherein the front frame of the guide rail and the guide rail and flat The position or its forward position intersecting manner, characterized in that the hinge base for supporting the corner blades are provided.

In the deflector according to the first aspect, since the corner blade is separated from the front blade and can be opened and closed, a storage groove for the corner blade becomes unnecessary. Therefore, the corner blade can be provided in the corner portion even when there is no space for providing the storage groove in the corner portion as in the case where the guide rail is extended forward.
Here, the hinge base that supports the corner blade can be fitted into a groove formed in the guide rail.

According to a third aspect of the present invention, the deflector according to the second aspect is configured such that the corner blade is elastically biased upward and opens and closes in conjunction with a lifting operation of the front blade. It is characterized by that.

In the deflector as claimed in claim 3 , since the corner blade is elastically biased upward and opens and closes in conjunction with the raising and lowering operation of the front blade, it is necessary to separately provide a power means for opening and closing the corner blade. Therefore, the opening / closing mechanism can be simplified.

According to such a deflector, the blade (corner blade) can be provided in the corner portion even if there is no space for providing the storage groove in the corner portion.
In addition, when the corner blade is elastically biased upward and is configured to open and close in conjunction with the raising and lowering operation of the front blade, there is no need to separately provide power means for opening and closing the corner blade, The opening / closing mechanism can be simplified.

  Next, a deflector according to an embodiment of the present invention will be described with reference to the drawings as appropriate.

  FIG. 1 to be referred to is a perspective view of an opening when the vehicle to which a deflector according to an embodiment of the present invention is applied is fully opened. Moreover, FIG. 2 is a figure explaining the state by which the deflector was accommodated in the inner frame about the A section of FIG. 1 at the time of full closure. 3 is a schematic cross-sectional view of the front blade and the corner blade before standing (a) and after standing (b) as seen from the direction of arrows BB in FIG. 2, and FIG. It is the cross-sectional schematic before standing (a) and after standing (b) seen from the -C line arrow direction.

As shown in FIG. 1, a deflector 1 according to an embodiment of the present invention includes a front blade 2, arms 3 and 3 that raise and lower the front blade 2, and corner blades 4 and 4 provided outside the front blade 2. And. As will be described later, the front blade 2 moves up and down in the direction of the arrow in the figure in conjunction with the movement of the slide roof 7 attached to the opening 6 formed in the fixed roof 5 of the vehicle. (In FIG. 1, the upper surface of the front blade 2 at the time of storage is shown by a dotted line).
As shown in FIG. 2, when fully closed, the front blade 2 is stored along the wall surface 9 a of the drainage groove 9 provided in the front frame 8, and the corner blade 4 is It arrange | positions in the closed state in the corner part 10 located in the outer side of the side edge part 2a.

  The side frame 11 includes a guide rail 12 for guiding a support portion (not shown) fixed to the lower side portion of the slide roof 7 (see FIG. 1) in the front-rear direction, and the support portion in the front-rear direction. An insertion groove 14 for the push-pull cable 13 to be moved and a drainage groove 15 are provided. The guide rail 12 is fixed to the bracket 16 and is disposed in a state of protruding forward from the front outer edge portion 8 a of the front frame 8. The drainage groove 9 provided in the front frame 8 has a downward slope 9b in the front portion intersecting with the guide rail 12, and the drainage groove 9 is configured to pass below the guide rail 12. Therefore, rainwater flowing through the drainage groove 9 passes through the downward slope 9 b and the guide rail 12 and is discharged from the drainage hole 17. Further, since the drainage groove 15 provided in the side frame 11 is connected to the descending slope 9c provided in the front frame 8, rainwater flowing through the drainage groove 15 passes through the descending slope 9c and is drained. 17 is discharged.

  As shown in FIG. 3, the front blade 2 is supported by the front end 3 a of the arm 3 and supported by a front support member 18 provided on the side frame 11 via a link 19. The arm 3 is elastically biased upward by a leaf spring 21 whose rear end 3b is pivotally attached to a rear support member 20 provided on the side frame 11 and further fixed at one end to the rear support member 20. Has been. Thus, when fully closed, the arm 3 is pushed downward by the slide roof 7 (see FIG. 1), and the front blade 2 is stored along the wall surface 9a of the drainage groove 9 (FIG. 3A). When the slide roof 7 moves rearward, the arm 3 whose restriction by the lower surface of the slide roof 7 is released rises due to the elastic force of the leaf spring 21, and the front blade 2 rises along the front edge 6 a of the opening 6. (FIG. 3B). Since the wind noise increases as the protrusion D of the front blade 2 increases, it is preferable to adjust the protrusion D of the front blade 2 so that the wind noise does not become noticeable.

  As shown in FIG. 4, a hinge base 22 that supports the corner blade 4 is provided on the guide rail 12. Since the corner blade 4 is pivotally attached to a pivot pin 22a provided on the hinge base 22, the corner blade 4 is separated from the front blade 2 and can be opened and closed. Thereby, since the storage groove of the corner blade 4 becomes unnecessary, the corner blade 4 can be provided in the corner portion 10 even if the guide rail 12 is extended forward.

  Further, a torsion coil spring 22b that elastically biases the corner blade 4 upward is wound around the pivot pin 22a. Further, the corner blade 4 is wound around the front end 3a of the arm 3 when fully closed. A restricting portion 3b that is pressed from above is provided. Thereby, in the state in which the front blade 2 is stored, the corner blade 4 is pushed by the lower surface of the restricting portion 3b to be in a closed state (FIG. 4A), and when the front blade 2 stands, The corner blade 4 whose restriction by the lower surface of the portion 3b is released is opened by the elastic force of the torsion coil spring 22b (FIG. 4B). For this reason, it is not necessary to separately provide a power means for opening and closing the corner blade 4, and the opening and closing mechanism can be simplified.

As mentioned above, although preferable embodiment was described, this invention is not limited to the said embodiment. For example, in the above-described embodiment, the corner blade is opened and closed by elastically biasing the corner blade upward, but a corner blade that is electrically opened and closed may be provided.
In the above embodiment, the corner blade is elastically urged by the torsion coil spring. However, the elastic urging means of the present invention is not limited to this, and the corner blade can be elastically urged upward. If it is good.
Further, the lifting means for the front blade is not limited to the above embodiment. For example, in the above-described embodiment, the structure that moves up and down in conjunction with the back and forth movement of the slide roof is used. However, a mechanism that can independently perform the lifting and lowering operation of the front blade may be provided.
