  By the way, in the vehicle deflector device of Patent Document 1, since there is a gap between the rear end portion of the arm portion and the support shaft portion, there is a limit in suppressing the deflection of the deflector, and abnormal noise is generated due to vehicle vibration. there is a possibility. Alternatively, if it is necessary to control the deflection of the deflector without fail, it is necessary to manage the product with tighter tolerances or to apply high-viscosity grease, which necessitates an increase in manufacturing man-hours and costs. End up.

  An object of the present invention is to provide a vehicle deflector device that can suppress the occurrence of abnormal noise due to vehicle vibration by suppressing the displacement of the deflector.

  In order to solve the above-mentioned problem, the invention according to claim 1 is arranged at a front end portion of an opening portion formed in a roof portion of a vehicle, and the opening operation of the movable panel that opens and closes the opening portion is performed. A deflector which is deployed on the surface of the roof part and is stored below the surface of the roof part with the closing operation of the movable panel; and the deflector of the roof part is opened with the opening operation of the movable panel. A deflector device for a vehicle comprising an urging member that urges so as to be developed on a surface, wherein the deflector is continuous with a wind cut portion extending in a vehicle width direction and both ends of the wind cut portion in the vehicle width direction. A pair of arm portions extending to the rear side of the vehicle, provided on both edges of the opening in the vehicle width direction, and a support portion that rotatably supports the rear end portion of the arm portion, An arcuate guide surface centered on the center of rotation of the rear end of the arm; A pair of holding members that reduce positional deviation in the vehicle front-rear direction and the vertical direction of the arm part by cooperation of the support part and the guide surface, and formed on each holding member, An abutting wall portion that contacts one side surface in the vehicle width direction of the end portion and the abutting wall portion that is formed on each holding member and elastically contacts the other side surface in the vehicle width direction of the rear end portion of the arm portion. The gist of the present invention is that it includes a bending portion that holds the rear end portion of the arm portion in the vehicle width direction in cooperation with the vehicle.

  According to this configuration, it is possible to reduce the positional deviation of the arm portion (deflector) in the vehicle front-rear direction and the vertical direction by the cooperation of the support portion and the guide surface. Further, the rear end portion of each arm portion of the deflector is elastically sandwiched in the vehicle width direction by the cooperation of the abutting wall portion and the bending portion, thereby suppressing the displacement in the direction. Can do. As described above, the displacement of the deflector can be suppressed in a plurality of directions, and the generation of abnormal noise due to vehicle vibration can be suppressed.

  According to a second aspect of the present invention, in the vehicle deflector device according to the first aspect, the support portion is a support pin having an axis extending in the vehicle width direction, and the guide surface is a vehicle front side of the support pin or An arcuate guide surface centered on the axis of the support pin located on the rear side of the vehicle, formed at the rear end of each arm, and inserted through the support pin so as to be relatively rotatable; A gist of the invention is that it includes an arc-shaped sliding contact surface that is formed at the rear end of each arm and is in sliding contact with the guide surface.

  According to this configuration, the rear end portion of each arm portion of the deflector is inserted into the support pin so that the insertion portion is relatively rotatable, and the sliding surface comes into sliding contact with the guide surface. It is assembled to each holding member in such a manner that it is sandwiched between the support pin and the guide surface in the vehicle front-rear direction. Accordingly, it is possible to suppress the positional deviation of the arm portions (deflectors) in the vehicle front-rear direction. In particular, if the insertion portion extends to above and below the support pin, it is possible to suppress the positional deviation of the arms (deflectors) in the vehicle vertical direction.

  According to a third aspect of the present invention, in the vehicle deflector device according to the second aspect, the insertion portion is open to the rear side of the vehicle, and the support pin can be inserted in a radial direction centering on the axis of the support pin. The gist is that it is a groove.

  According to this configuration, the rear end portion of each arm portion of the deflector is at a position where interference with the guide surface or the bending portion can be avoided, and the diameter of the support pin in the groove portion with its axis as the center. By inserting in the direction, the support pin can be inserted so as to be relatively rotatable. In this state, the sliding contact surface is slidably contacted with the guide surface, and the rear end portion of the arm portion is elastically clamped in the vehicle width direction by the cooperation of the contact wall portion and the bending portion.

Is the gist.

  According to this configuration, the deflector released from the movable panel when the movable panel is opened causes the torsion coil spring to move the tip of the second end in one direction along the guide recess. While being elastically restored, it is developed on the surface of the roof portion. Alternatively, the deflector pressed against the movable panel with the closing operation of the movable panel causes the torsion coil spring to elastically deform while moving the tip of the second end portion in the other direction along the guide recess. Thus, it is stored below the surface of the roof portion. In this case, the second end of the torsion coil spring that defines the position (posture) of the deflector is sandwiched between the first side wall and the second side wall, and the tip is inserted into the guide recess. In this way, it is possible to prevent and hold firmly in particular in the vehicle width direction.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a sunroof device 11 mounted on a vehicle roof 10 as a roof portion of a vehicle such as an automobile. As shown in the figure, the vehicle roof 10 has a substantially square roof opening 10a, and includes a deflector 12 disposed at an edge of the roof opening 10a on the front side of the vehicle, and further moves in the vehicle longitudinal direction. A rectangular movable panel 13 made of, for example, a glass plate is provided to open and close the roof opening 10a.

  The deflector 12 is attached so as to be capable of a so-called tilt-up operation in which the front part moves upward by rotating around its rear part, and performs a tilt-up operation in conjunction with the opening operation of the movable panel 13. A state in which the deflector 12 is in a deployed position projecting upward from the upper surface of the vehicle roof 10 in accordance with the tilt-up operation is referred to as a deployed state, and the movable panel 13 is pressed into the movable panel 13 as the movable panel 13 is closed. The state in the storage position that fits below is called the storage state. The deflector 12 is in an unfolded state when the roof opening 10a is opened, thereby preventing air vibrations due to wind being caught in the vehicle interior.

  FIG. 2 is a plan view schematically showing the sunroof device 11. As shown in the figure, the sunroof device 11 includes a pair of guide rails 21 disposed and fixed at both side edges in the vehicle width direction of the roof opening 10a. Each guide rail 21 is made of, for example, an extruded material of aluminum alloy, has a constant cross section in the longitudinal direction, and extends in the vehicle front-rear direction.

  A connecting member 22 is movably guided and supported on each guide rail 21. And both the edge parts of the vehicle width direction of the said movable panel 13 are being fixed and supported by the both connection members 22 in the aspect bridge | crosslinked between these. The connecting member 22 moves the movable panel 13 to open and close the roof opening 10 a as it moves along the guide rail 21.

  Further, the sunroof device 11 includes a front housing 23 made of a resin material that extends in the vehicle width direction and connects the front end portions of both guide rails 21. A drive gear 25 made up of a spur gear that is rotationally driven by a drive source (for example, an electric motor) is installed at an intermediate portion in the longitudinal direction of the front housing 23. The drive gear 25 is rotatably supported by the front housing 23 around a rotation shaft extending in the vehicle height direction (a direction orthogonal to the paper surface).

  The front housing 23 movably accommodates a single rack gear-like toothed belt 26 made of a resin material meshing with the drive gear 25 at the front portion of the drive gear 25, and at the rear portion of the drive gear 25. A rack gear-like single toothed belt 27 made of a resin material meshing with the drive gear 25 is movably accommodated. One end of the toothed belt 26 that has entered the one guide rail 21 is connected to the connecting member 22 supported by the guide rail 21, and the tooth that has entered the other guide rail 21. One end of the attached belt 27 is connected to the connecting member 22 supported by the guide rail 21.

  In such a configuration, it is assumed that the drive gear 25 is rotated counterclockwise in the drawing. At this time, the toothed belts 26 and 27 are pushed out to the side where the leading ends connected to the connecting member 22 enter the guide rail 21, and the connecting member 22 moves rearward along the guide rail 21. . As a result, the movable panel 13 moves rearward of the vehicle and the roof opening 10a is opened.

  On the other hand, it is assumed that the drive gear 25 is rotated clockwise in the figure. At this time, the end portions of the toothed belts 26 and 27 connected to the connecting member 22 are pulled to the side where they are pulled out from the guide rail 21, and the connecting member 22 moves along the guide rail 21 toward the front of the vehicle. As a result, the movable panel 13 moves forward of the vehicle and the roof opening 10a is closed.

  Next, the deflector 12 and its mounting structure will be described on behalf of the right side toward the front of the vehicle. 3 and 4 are an enlarged plan view and a perspective view of the right front portion of the sunroof device 11. As shown in the figure, the front end of each guide rail 21 is formed with substantially rectangular locking holes 21a and 21b arranged in parallel in the vehicle front-rear direction, and at the rear of the locking hole 21b in the vehicle. The substantially rectangular locking holes 21c and 21d are formed in parallel in the vehicle front-rear direction. These locking holes 21a to 21d open in the vehicle height direction. And the holder 30 which consists of a resin material as a holding member engaged with these latching holes 21a-21d is being fixed to the guide rail 21. As shown in FIG.

  That is, as shown in FIGS. 6A and 6B, a side view and a bottom view show that the holder 30 has a hook-like shape that protrudes forward from the main body 31 and the front end of the main body 31 closer to the inside in the vehicle width direction. The extending piece 32 is integrally provided. The front end portion of the main body 31 is formed with a generally L-shaped locking piece 31a extending in the width direction and bent from the lower end toward the front side of the vehicle over the entire length in the width direction. In addition, a locking piece 31b having a substantially L shape in side view is formed at the rear end of the main body 31 closer to the inner side in the vehicle width direction and extends downward and bends from the lower end toward the front of the vehicle. Furthermore, the main body 31 has a first extending piece 31c extending rearward from the front end of the vehicle width direction outer end, and the vehicle width via a step from the rear end of the first extending piece 31c. A second extending piece 31d that shifts outward in the direction and further extends rearward of the vehicle is provided. A bent portion 33 having an arc shape in a bottom view is provided on the inner surface of the first extending piece 31c. Further, a support pin 34 as a substantially cylindrical support portion extending in the vehicle width direction is projected on the inner side surface of the second extension piece 31d so as to be bridged between the engagement piece 31b. ing. The rear end surface of the locking piece 31a near the vehicle width direction forms an arcuate guide surface 35 (see FIG. 5) centered on the axis of the support pin 34.

  The main body 31 forms a space S that is partitioned by the extending pieces 31c and 31d, the support pin 34, the guide surface 35, and the like and opens in the vehicle height direction. Accordingly, the space S is shrunk in the vehicle width direction by the amount of the bending portion 33 in the first extending piece 31c. The main body 31 forms an abutting wall portion 36 on the facing surface of the bending portion 33 in the vehicle width direction.

  In such a configuration, as shown in FIG. 3, the holder 30 is inserted and positioned at the distal end of the extended piece 32 whose base end is inserted into the locking hole 21b from above, into the locking hole 21a from below. The locking pieces 31a and 31b are fixed to the guide rail 21 by being hooked on the front end edges of the locking holes 21c and 21d.

  As shown in FIG. 4, the front housing 23 is integrally formed with a spring holding portion 40 at a boundary portion closer to the inner side in the vehicle width direction with each guide rail 21. Each spring holding portion 40 is arranged to be shifted in the vehicle width direction with respect to the holder 30. Each spring holding portion 40 has a first side wall portion 41 and a second side wall portion 42 arranged side by side in the vehicle width direction, and is formed in such a manner that the first side wall portion 41 is vertically divided except for the front end portion. The guide recess 43 (see FIG. 5). That is, the spring holding portion 40 forms a space that opens upward and in the vehicle front-rear direction between the first and second side wall portions 41, 42, and in the vehicle recess direction inner side facing the second side wall portion 42 in the guide recess 43. And it opens in the vehicle rear direction. A longitudinal groove 43a is formed at an intermediate portion in the longitudinal direction of the guide recess 43 so as to open upward. At the lower end of the vertical groove 43a, a throttle portion 43b for reducing the opening amount is formed.

  The deflector 12 includes a wind-cut portion 51 that extends in the vehicle width direction along the front housing 23 and a pair of arm portions 52 that extend to the vehicle rear side continuously from both ends of the wind-cut portion 51 in the vehicle width direction. Have And the wind-cut part 51 has the positioning wall part 51a arrange | positioned on the vehicle front extension of the vehicle width direction inner surface of each arm part 52, and is arrange | positioned on the vehicle front extension of the said spring holding | maintenance part 40. Positioning wall portion 51b. Both positioning wall portions 51a and 51b are arranged to face each other in the vehicle width direction.

  At the rear end portion of each arm portion 52, a groove portion 53 is formed as an insertion portion through which the support pin 34 of the holder 30 is inserted so as to be relatively rotatable. The groove 53 has a substantially U shape in a side view so that the support pin 34 can be inserted in a radial direction centering on the axis of the support pin 34 by opening to the rear side of the vehicle. Further, at the rear end portion of each arm portion 52, an arc shape arranged on the vehicle rear side of the guide surface 35 of the holder 30 and slidably contacting the guide surface 35 as the arm portion 52 around the support pin 34 rotates. A sliding contact surface 54 is formed.

  Accordingly, the rear end portion of each arm portion 52 is inserted into the support pin 34 so that the groove portion 53 is relatively rotatable, and the sliding contact surface 54 is in sliding contact with the guide surface 35, so that the support pin 34 and the guide surface 35 are in contact with each other. The holder 30 is assembled in such a manner that it is sandwiched in the vehicle longitudinal direction. Thereby, the positional deviation of each arm part 52 (deflector 12) in the vehicle front-rear direction is suppressed. Moreover, the groove part 53 is extended to the upper direction and the downward direction of the support pin 34, and the position shift of the vehicle up-down direction of each arm part 52 (deflector 12) is suppressed collectively.

  At this time, as shown in FIGS. 7 (a) and 7 (b), the rear end portion of each arm portion 52 is in contact with the inner wall surface in the vehicle width direction and the outer wall surface in the vehicle width direction. The flexible portion 33 is in elastic contact with the elastic member. Accordingly, the rear end portion of each arm portion 52 is sandwiched in the vehicle width direction by the cooperation of the bending portion 33 and the abutting wall portion 36, and positional deviation in the vehicle width direction is also suppressed.

  A torsion coil spring 60 as an urging member is installed in the wind cut portion 51 of the deflector 12. The coil spring 60 is arranged between the positioning wall portions 51a and 51b and extends in the tangential direction from the outer end of the coil portion 61 in the vehicle width direction. It has the 1st end part 62 latched by the part 51 (placement wall part 51a), and the 2nd end part 63 extended in the tangential direction from the vehicle width direction inner side end of the coil part 61. As shown in FIG. That is, the coil spring 60 is arranged to be shifted in the vehicle width direction (inward) from the front end of each arm portion 52, and is positioned and accommodated in the wind cut portion 51 by the positioning wall portions 51a and 51b. Yes. In other words, a part of the wind cut portion 51 functions as a cover for the coil spring 60.

  The second end portion 63 of the coil spring 60 has a tip 63a bent outward in the vehicle width direction, and the second end portion 63 of the coil spring 60 is between the first and second side wall portions 41 and 42. The tip 63a is connected to the spring holding portion 40 by being inserted into the guide recess 43 so as to be movable in the vehicle front-rear direction. The coil spring 60 is, for example, the side where the first end 62 rotates in the clockwise direction in the figure with respect to the second end 63 (tip 63a), that is, the first end 62 (wind) with respect to the second end 63. The urging force on the side where the cut portion 51) is raised is generated. The coil spring 60 raises the first end 62 while moving the tip 63a of the second end 63 forward of the vehicle along the guide recess 43 when returning to elasticity.

Here, the operation of the present embodiment will be described collectively.
First, it is assumed that the deflector 12 is in the retracted state. When the movable panel 13 is opened, the deflector 12 released from the movable panel 13 is elastically restored while the coil spring 60 moves the tip 63a of the second end 63 along the guide recess 43 forward of the vehicle. Then, it is developed on the surface of the vehicle roof 10. At this time, the deployment amount of the deflector 12 on the surface of the vehicle roof 10 is determined by the position of the front end of the guide recess 43 that restricts the movement of the tip 63a of the second end 63 to the front of the vehicle.

  Subsequently, in the deflector 12 in the unfolded state that is pressed against the movable panel 13 with the closing operation of the movable panel 13, the coil spring 60 moves the tip 63 a of the second end 63 to the rear of the vehicle along the guide recess 43. It is stored below the surface of the vehicle roof 10 by being elastically deformed. Note that the length of the guide recess 43 in the vehicle front-rear direction is set so that the tip 63 a of the second end 63 does not come out behind the guide recess 43 even when the deflector 12 is stored.

As described above, the deflector 12 is deployed and stored in conjunction with the opening / closing operation of the movable panel 13.
Next, an assembly mode of the deflector 12 and the like will be described.

  As shown by a two-dot chain line in FIG. 5, the rear end portion of each arm portion 52 of the deflector 12 is provided with the support pin 34 in the groove portion 53 at a position where interference with the guide surface 35 or the bending portion 33 can be avoided. By inserting the support pin 34 in a radial direction around the axis, the support pin 34 can be inserted in a relatively simple manner so as to be relatively rotatable. In this state, the slidable contact surface 54 is slidably contacted with the guide surface 35, and the rear end portion of the arm portion 52 is elastically clamped in the vehicle width direction by the cooperation of the bending portion 33 and the contact wall portion 36. However, the arm 52 (deflector 12) is assembled to the holder 30 by rotating the arm 52 around the support pin 34 (see FIG. 7).

  Next, the second end 63 of the coil spring 60 previously installed on the deflector 12 is disposed between the first and second side wall portions 41 and 42 of the spring holding portion 40, and the tip 63a is guided from the vertical groove 43a to the guide recess. Enter 43. At this time, the distal end 63a enters the guide concave portion 43 while elastically deforming the throttle portion 43b, thereby preventing return movement to the vertical groove 43a, that is, dropping from the vertical groove 43a. The second end portion 63 is sandwiched between the first and second side wall portions 41 and 42, and the tip 63a is inserted into the guide recess 43, so that the second end portion 63 is firmly held and held particularly in the vehicle width direction. .

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the cooperation of the support pin 34 and the guide surface 35 can reduce the positional deviation of the arm portion 52 (deflector 12) in the vehicle front-rear direction and the vertical direction. That is, the rear end portion of each arm portion 52 of the deflector 12 is inserted into the support pin 34 so that the groove portion 53 is relatively rotatable, and the sliding contact surface 54 is slidably contacted with the guide surface 35. It is assembled to the holder 30 so as to be sandwiched between the surfaces 35 in the vehicle longitudinal direction. Accordingly, it is possible to suppress the positional deviation of each arm 52 (deflector 12) in the vehicle front-rear direction. Moreover, since the groove part 53 is extended to the upper direction and the downward direction of the support pin 34, the position shift of the vehicle up-down direction of each arm part 52 (deflector 12) can be suppressed collectively. Furthermore, the rear end portion of each arm portion 52 of the deflector 12 is elastically sandwiched in the vehicle width direction by the cooperation of the bending portion 33 and the abutting wall portion 36, thereby suppressing the positional deviation in the direction. Can do. As described above, the displacement of the deflector 12 can be suppressed in a plurality of directions by using the frictional force generated between the holder 30 and the rear end portion (rotation center portion) of each arm portion 52. Abnormal noise generation can be suppressed. And the management of tolerance can be relaxed, or the necessity of applying high-viscosity grease can be eliminated.

  (2) In the present embodiment, the rear end portion of each arm portion 52 of the deflector 12 is a position where interference with the guide surface 35 or the bending portion 33 can be avoided, and the support pin 34 is centered on the axis of the groove portion 53. By inserting the support pin 34 in a radial direction, the support pin 34 can be inserted in a relatively simple manner without being deformed, for example, without deforming the deflector 12. In this state, the slidable contact surface 54 is slidably contacted with the guide surface 35, and the rear end portion of the arm portion 52 is elastically clamped in the vehicle width direction by the cooperation of the bending portion 33 and the contact wall portion 36. On the other hand, the arm portion 52 (deflector 12) can be easily assembled to the holder 30 by rotating the arm portion 52 with the support pin 34 as a fulcrum.

  (3) In the present embodiment, the deflector 12 released from the movable panel 13 with the opening operation of the movable panel 13 is configured so that the torsion coil spring 60 moves the tip 63 a of the second end 63 along the guide recess 43. By moving back and elastically returning, the vehicle roof 10 is developed. Alternatively, the deflector 12 pressed by the movable panel 13 with the closing operation of the movable panel 13 is elastic while moving the torsion coil spring 60 with the tip 63a of the second end 63 along the guide recess 43 toward the rear of the vehicle. By being deformed, it is stored below the surface of the vehicle roof 10. In this case, the second end 63 of the torsion coil spring 60 that defines the position (posture) of the deflector 12 is sandwiched between the first and second side walls 41, 42, and the tip 63 a is inserted into the guide recess 43. Thus, it is possible to prevent and hold firmly, particularly in the vehicle width direction.

  On the other hand, when the second end 63 of the torsion coil spring 60 is firmly held in this way, for example, when the torsion coil spring 60 is displaced in the vehicle width direction due to the influence of an external force or the like, The possibility that the redundant second end 63 deforms (plastic deformation) increases. However, the possibility of such deformation (plastic deformation) is particularly suppressed because the displacement of the deflector 12 (arm portion 52) in the vehicle width direction is suppressed by the cooperation of the bending portion 33 and the contact wall portion 36. Can be reduced.

  (4) In the present embodiment, the torsion coil spring 60 is arranged so as to be shifted from the front end of the arm portion 52 toward the vehicle width inner side, so that, for example, the coil portion 61 is not restricted by the width of the arm portion 52. The degree of freedom of selection of the elastic force (spring force) that can be generated can be improved.

In addition, you may change the said embodiment as follows.
In the embodiment, the support pin 34 may be cantilevered by the second extending piece 31d, for example. In this case, the rear end portion of each arm portion 52 may be a circular hole-shaped insertion portion through which the support pin is inserted. In addition, when inserting a support pin into an insertion part with such a structure, what is necessary is just to insert in an insertion part from the free end side, for example, elastically deforming a support pin.

In the above-described embodiment, the guide surface 35 (and the arc-shaped sliding contact surface 54 slidably contacting the guide surface 35) may be disposed on the vehicle rear side of the support pin 34.
In the above-described embodiment, an arc-shaped extending portion that protrudes rearward of the vehicle is formed at the rear end portion of each arm portion 52, and an upper arc-shaped surface and a lower circle that are in sliding contact with the upper surface and the lower surface of the extending portion, respectively The rear end portion of the arm portion 52 may be rotatably supported by the arcuate surface while reducing the positional deviation of the arm portion 52 (deflector 12) in the vehicle front-rear direction and the vertical direction.

In the embodiment described above, for example, a leaf spring may be employed instead of the torsion coil spring 60 as the biasing member.
In the above-described embodiment, the holder 30 may be fixed directly to the edge in the vehicle width direction of the roof opening 10a as long as the arrangement of the deflector 12 and the like is not restricted.
