Description

Technical Field

[0001] The invention relates to a deflector device for a vehicle skylight. Background Art

[0002] A deflector device is provided in a vehicle sunroof having a sunroof panel on the roof. When an opening of the fixed roof is opened by sliding the movable roof panel, a deflector provided along the front edge of the opening protrudes upward from the opening.

[0003] As such a deflector device, there is known a deflector member that is expandable and made of a soft sheet material, and the deflector member is connected to a rigid deflector base member mounted on the roof and a rotatable expansion bracket (Patent Document 1). In this deflector device, grooves for a fairlead (welding rod / pipe) connected to the deflector member (deflector body) are formed on the deflector base member and the expansion bracket (deflector blade), and the fairlead is inserted into each groove. The fairlead can be injection molded on the deflector body, is made of elastically deformable plastic, and is held in the groove by the head of a screw member that is screwed into the deflector base member or the deflector blade.

[0006] Patent Document 1: German Patent Invention No. 102006043275 Summary of the invention

[0007] Problems to be solved by the invention

[0008] However, in the deflector device described in Patent Document 1, since the fairlead (i.e., the held component) is held in the groove by the head of the screw component, when the screw component is loosened, the locking of the head may be loosened and the fairlead may fall out of the groove. In addition, since the tension on the deflector body is concentrated on the portion of the fairlead that abuts against the head of the screw component, the fairlead may bend and uneven tension may act on the deflector body.

[0009] In view of the above background, an object of the present invention is to suppress the deflector body from falling off and loosening from the deflector blades.

[0010] Means for solving problems

[0011] In order to solve the above-mentioned problems, one embodiment of the present invention is a deflector device (10) for a sunroof for a vehicle, comprising: a cloth-like deflector body (11) which can be folded and unfolded and is arranged along the front edge of an opening (2) formed on a fixed roof (3); a retained component (21) which is arranged along the upper edge of the deflector body; a deflector blade (14) which is formed with a groove (22) extending in the vehicle width direction to accommodate the retained component; and a pair of arms (16) which support either lateral end of the deflector blade. The invention relates to a method for manufacturing a plurality of guide plate blades, wherein the guide plate blades are configured to extend and retract from the opening; and a retaining member (23) fixed to the guide plate blades to retain the retained member in the groove, the retaining member comprising: a snap-fitting member (24) having one end (24a) snap-fitting with the retained member in the groove; and a fixing member (25) extending from the other end (24b) of the snap-fitting member at a certain angle to the snap-fitting member and having a plurality of insertion holes (26) for a fastening member (27) mounted on the guide plate blades.

[0012] According to this embodiment, since the retaining member is fixed to the guide vane by the fastening member inserted into the insertion hole, the retaining member is difficult to fall off from the guide vane. In addition, since the retaining member includes the engaging portion and the fixing portion inclined or at a certain angle relative to the engaging portion, it is difficult to bend. Thus, the guide vane body can be prevented from loosening.

[0013] In the above aspect, preferably, the held member (21) is folded back at the bottom of the groove (22) to be accommodated in the groove so as to sandwich the engaging portion (24).

[0014] According to this aspect, the held component is difficult to be removed even if it is not bonded or coupled to the engaging portion, thereby preventing the held component from falling out of the groove of the guide vane.

[0015] In the above aspect, preferably, portions (31, 32) of the held member (21) that sandwich the engaging portion (24) are respectively formed with projections (35, 34) that project toward the engaging portion.

[0016] According to this aspect, the two parts of the held member sandwiching the engagement portion can be brought into contact with the engagement portion over a long region in the vehicle width direction. This prevents any part of the deflector body from loosening due to the held member being displaced relative to the engagement portion.

[0017] In the above embodiment, preferably, the fixing portion (25) extends in the vehicle width direction by a length corresponding to the length of the engaging portion (24) in the vehicle width direction, and the retaining member (23) is L-shaped in a cross section perpendicular to the vehicle width direction.

[0018] According to this aspect, the bending rigidity of the holding member over the entire length in the vehicle width direction is improved, thereby suppressing the bending of the holding member and suppressing the sag of the deflector body.

[0019] In the above aspect, preferably, a protrusion (46) is provided near a portion of the guide plate blade (14) where the fastening member (27) is installed, and a positioning hole (44, 45) engaging with the protrusion is formed in the fixing portion.

[0020] According to this aspect, the projection engages with the positioning hole, thereby accurately aligning the member with respect to the guide vane. This makes it easy to attach the fastening member to the guide vane.

[0021] In the above-mentioned method, preferably, the guide plate blade (14) is formed integrally with the pair of arms in a manner continuous with the pair of arms via a pair of curved portions (15), and the retaining member (23) includes a central member (41) arranged in the center of the vehicle width direction and a pair of curved members (42) arranged at the curved portions, and the curved members are respectively configured to retain the end of the retained member (21) at a portion of the groove (22) formed on the corresponding arm (16).

[0022] According to this aspect, even if there is a manufacturing error, the end of the held member can be held in the groove formed in the bent portion and the arm by the pair of bent members without being affected by the positional deviation caused by the manufacturing error. This prevents the end of the deflector body from loosening.

[0023] Effects of the Invention

[0024] According to the above aspect, it is possible to suppress the deflector body from falling off and loosening from the deflector blades. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description, the front-rear direction and the lateral direction (vehicle width direction) are defined based on the traveling direction of the vehicle to which the present invention is applied.

[0034] Figure 1 FIG. 1 is a perspective view of a roof 1 of a car to which the deflector device 10 according to the embodiment is applied. Figure 1 As shown, the roof 1 of the automobile has a fixed roof 3 having a substantially rectangular opening 2 formed at the front and a sunroof device 4 arranged in a manner capable of blocking the opening 2, thereby constituting a sunroof. The sunroof device 4 has a front panel 5 that closes the front portion of the opening 2 and a rear panel 6 that closes the rear portion of the opening 2. The front panel 5 and the rear panel 6 are arranged along the roof 1 in a manner such that their upper surfaces are flush with the upper surface of the roof 1. The front panel 5 is a movable panel that can move relative to the roof 1, and the rear panel 6 is a fixed panel that cannot move relative to the roof 1. The front panel 5 is arranged to be able to slide in the front-to-back direction relative to the fixed roof 3, and the front portion of the opening 2 is opened by sliding rearward, and the front portion of the opening 2 is closed by sliding forward.

[0035] A sunroof frame 7 supporting the front panel 5 and the rear panel 6 is arranged below the fixed roof 3 (on the vehicle compartment side). The sunroof frame 7 includes a pair of side members, a front member 8 (see FIG. Figure 3 ) and a rear cross beam. The side members extend in the front-to-rear direction along the two side edges of the opening 2. The side members are formed of, for example, an extruded product of an aluminum alloy. The front member 8 extends in the lateral direction along the front edge of the opening 2, connecting the front ends of a pair of side members. The rear cross beam extends in the lateral direction along the rear edge of the opening 2, connecting the rear ends of the pair of side members. The front member 8 and the rear cross beam are formed of, for example, an injection molded product of a resin.

[0036] The sunroof device 4 is an external sliding type in which the front panel 5 is tilted upward from a closed position in which the front part of the opening 2 is closed and slides rearward on the upper side of the rear panel 6. The front panel 5 is driven by a known driving mechanism in which the front slider and the rear slider are driven to slide in the front-to-back direction along the guide rails formed on the side members to perform tilting and sliding movements. In this specification, a detailed description of the driving mechanism is omitted.

[0037] A deflector device 10 is provided at the front edge of the opening 2, and protrudes upward from the opening 2 when the opening 2 is open, and is stored under the opening 2 when the opening 2 is closed. The deflector device 10 is assembled to the sunroof frame 7 and constitutes a part of the sunroof device 4. The sunroof device 4 is configured as a unit mounted on the roof 1 by being fixed to the fixed roof 3 via the sunroof frame 7.

[0038] Figure 2 2 is a perspective view of the deflector device 10. The deflector device 10 is substantially symmetrical. The deflector device 10 is arranged along the front edge of the opening 2 and has a cloth-like deflector body 11 that can be folded and unfolded. The deflector body 11 is made of a fine mesh material of soft cloth. The lower edge of the deflector body 11 is connected by a lower bracket 12 ( Figure 3 ) is mounted on the front member 8 of the sunroof frame 7 ( Figure 3 The upper bracket 13 is installed on the upper edge of the guide plate body 11.

[0039] The upper bracket 13 is a resin injection molded product, and includes a deflector blade 14 extending in the vehicle width direction and a pair of arms 16 integrally formed with the deflector blade 14 and extending rearward from a curved portion 15 formed at both ends of the deflector blade 14. The pair of arms 16 are supported at the rear end by a support member 17 mounted on the sunroof frame 7 so as to be rotatable around an axis X in the vehicle width direction. A pair of force applying members 18 ( Figure 2 Only the force applying member 18 on the right side is shown in the figure. The force applying member 18 is composed of a torsion coil spring in the example shown in the figure. In other embodiments, the force applying member 18 may also be composed of a leaf spring, a compression coil spring, a tension coil spring, etc. The pair of arms 16 causes the guide vane 14 to protrude from the opening 2 when the front panel 5 slides backward, and causes the guide vane 14 to retract into the opening 2 when the front panel 5 slides forward.

[0040] Figure 3 1 is a cross-sectional view of the deflector device 10, showing the deflector device 10 in an expanded state. Figure 2 and Figure 3 As shown, the lower bracket 12 is connected to the lower edge of the deflector body 11 by, for example, an adhesive. The lower bracket 12 is, for example, an injection-molded product of a resin, and has a claw 12a that engages with the front member 8 of the sunroof frame 7. Thus, the lower bracket 12 can be detachably mounted on the front member 8. By mounting the lower bracket 12 on the front member 8, the lower edge of the deflector body 11 is fixed to the front member 8.

[0041] The held member 21 is attached to the upper edge of the deflector body 11 by sewing. The held member 21 may be attached to the deflector body 11 by bonding or welding. The upper edge of the deflector body 11 is held by the deflector blade 14 via the held member 21. Figure 4yes Figure 3 The enlarged picture of the main part. Figure 3 and Figure 4 As shown, a groove 22 extending in the vehicle width direction is formed on the lower surface of the guide vane 14. The held member 21 is inserted into the groove 22 and held inside the groove 22 by a holding member 23 fixed to the guide vane 14.

[0042] The retaining member 23 is made of a metal plate and is L-shaped when viewed from above. Specifically, the retaining member 23 includes: a snap-fitting portion 24 whose one end, i.e., the upper end 24a, is snap-fitted with the retained member 21 inside the groove 22; and a fixing portion 25 which is continuous with the other end, i.e., the lower end 24b of the snap-fitting portion 24 disposed outside the groove 22. The fixing portion 25 extends from the lower end 24b of the snap-fitting portion 24 at a certain angle (90° in this embodiment) to the snap-fitting portion 24 and is fixed to the guide vane 14. Both the snap-fitting portion 24 and the fixing portion 25 extend in the vehicle width direction. A plurality of insertion holes 26 consisting of through holes are formed on the fixing portion 25 at intervals along the vehicle width direction. The fixing portion 25 is fixed to the guide vane 14 by a plurality of screw members 27 inserted into the insertion holes 26. The screw member 27 is a fastening member having a shaft portion 28 having an external thread and a head portion 29 . The shaft portion 28 is inserted into the insertion hole 26 and screwed into a threaded hole 30 formed in the guide vane 14 , thereby fixing the fixing portion 25 to the guide vane 14 via the head portion 29 .

[0043] As described above, the holding member 23 is fixed to the guide vane 14 by the screw member 27 inserted into the insertion hole 26, so the holding member 23 is difficult to fall off from the guide vane 14. In addition, the holding member 23 is made of metal and is difficult to bend because it includes the engaging portion 24 and the fixing portion 25 inclined with respect to the engaging portion 24. Thus, the guide vane body 11 can be prevented from being loosened.

[0044] The held component 21 is folded back at the bottom of the groove 22, and is in an inverted J shape when viewed from the side. The held component 21 is a resin extrusion molded product, and is formed of a material softer than the guide vane 14. The held component 21 has a base 31 coupled to the guide vane body 11, a front end 32 opposite to the base 31, and a connecting portion 33 connecting the base 31 and the front end 32. The connecting portion 33 is located at the bottom of the groove 22, and constitutes a folded portion for making the front end 32 and the base 31 opposite. The held component 21 is accommodated in the groove 22 in a manner that the engaging portion 24 of the holding component 23 is sandwiched. The engaging portion 24 of the holding component 23 engages with the folded portion of the held component 21 arranged at the bottom of the groove 22 by abutting. The fixing portion 25 is fixed to the guide vane 14 by the screw component 27, whereby the held component 21 is held inside the groove 22 by the engaging portion 24.

[0045] As described above, the held component 21 is folded back at the bottom of the groove 22 to be accommodated in the groove 22 with the engaging portion 24 sandwiched therein, and therefore, even if not bonded or combined with the engaging portion 24, it is difficult to be removed from the engaging portion 24. Thus, the held component 21 can be prevented from falling off from the groove 22 of the guide vane 14.

[0046] The front end portion 32 of the retained component 21 is formed thinner than the base portion 31 and the connecting portion 33. A pair of lips 34 extending in the vehicle width direction are integrally formed on the surface of the front end portion 32 facing the base portion 31. On the other hand, a protrusion 35 extending in the vehicle width direction is integrally formed on the surface of the base portion 31 facing the front end portion 32. The protrusion 35 is arranged at a position corresponding to the lips 34 and abuts against the front surface of the engaging portion 24. The pair of lips 34 abuts against the rear surface of the engaging portion 24. That is, the base portion 31 and the front end portion 32 of the retained component 21 sandwiching the engaging portion 24 are respectively formed with the lips 34 and the protrusion 35 as protrusions protruding toward the engaging portion 24. Therefore, the two parts of the retained component 21 sandwiching the engaging portion 24 abut against the engaging portion 24 over a long area in the vehicle width direction. As a result, a part of the deflector body 11 is prevented from loosening due to the displacement of the retained component 21 relative to the engaging portion 24.

[0047] Figure 5 13 is a bottom view of the upper bracket 13. Figure 5 As shown, the retaining member 23 is divided into five parts in the vehicle width direction. Specifically, the retaining member 23 includes a central member 41 disposed at the center of the guide vane 14 in the vehicle width direction, a pair of curved members 42 disposed at the curved portion 15 of the guide vane 14, and a pair of intermediate members 43 disposed between the central member 41 and the curved members 42. Each curved member 42 also extends rearward from the curved portion 15 and is mounted on a corresponding arm 16. Specifically, each arm 16 is formed such that the groove 22 formed on the guide vane 14 further extends through the curved portion 15 and the arm 16. As shown in FIG. Figure 2 Also shown in FIG. 1 , the end portion of the held member 21 extends in the front-rear direction and is held inside a groove 22 formed in the corresponding arm 16 .

[0048] Figure 6 yes Figure 5 FIG. VI is an enlarged view of the central part 41. Figure 6 As shown, an insertion hole 26 ( Figure 4) and two circular holes 44 (one of the circular holes 44 is hidden by the screw member 27) for positioning holes. Two oblong holes 45 serving as insertion holes 26 and positioning holes are formed at the left end of the central member 41. A circular protrusion 46 is formed at the portion of the upper bracket 13 corresponding to the two positioning holes. The circular hole 44 and the long hole 45 engaged with the protrusion 46 function as positioning holes for positioning the central member 41. A threaded hole 30 ( Figure 4 ), the central component 41 is fixed to the upper bracket 13 by a screw component 27 screwed into the threaded hole 30.

[0049] Figure 7 yes Figure 5 The enlarged view of part VII in FIG. 4 shows the middle part 43 on the right side. Figure 7 As shown, the intermediate member 43 is spaced apart from the central member 41. An insertion hole 26 ( Figure 4 ) and two circular holes 44 for positioning holes (one of the circular holes 44 is hidden by the screw member 27). Two oblong holes 45 serving as insertion holes 26 and positioning holes are formed at the right end of the middle member 43. An insertion hole 26 for the screw member 27 is also formed in the middle position of the middle member 43 (hidden by the screw member 27). A circular protrusion 46 is formed in the portion of the upper bracket 13 corresponding to the two positioning holes. A threaded hole 30 ( Figure 4 ), the intermediate component 43 is fixed to the upper bracket 13 by a screw component 27 screwed into the threaded hole 30.

[0050] Figure 8 yes Figure 5 The enlarged view of part VIII in FIG. 4 shows the curved part 42 on the right side. Figure 8 As shown, the curved member 42 is arranged with a gap between it and the intermediate member 43. A circular hole 44 (hidden by the screw member 27) serving as the insertion hole 26 for the screw member 27 and a notch 47 for positioning are formed at the front end of the curved member 42. The rear end of the curved member 42 has only the engaging portion 24 but no fixing portion 25. An oblong long hole 45 serving as a positioning hole is formed in a portion of the fixing portion 25 near the rear end of the curved member 42. A circular protrusion 46 is formed in a portion of the upper bracket 13 corresponding to the notch 47 and the positioning hole. Screw holes 30 ( Figure 4), the curved member 42 is fixed to the upper bracket 13 by the screw member 27 screwed into the threaded hole 30. The screw member 27 located at the rear end of the curved member 42 is locked to the end surface of the locking portion 24 by the protruding portion of the head 29.

[0051] like Figure 2 and Figure 3 , the bent member 42 is configured so that the end of the held member 21 is held inside the groove 22 formed on the corresponding arm 16. Therefore, even if there is a manufacturing error in the size of the upper bracket 13 and the holding member 23, the end of the held member 21 is held by the pair of bent members 42 in the groove 22 formed on the bent portion 15 of the upper bracket 13 and the arm 16, thereby suppressing the misalignment caused by the manufacturing error. As a result, the end of the deflector body 11 can be suppressed from being loosened.

[0052] In addition, even if there is no manufacturing error, since the upper bracket 13 is formed of resin and the holding member 23 is formed of metal, the holding member 23 may not match the groove 22 due to the difference in thermal expansion coefficient. In the present embodiment, the guide vane 14 is formed to include a central member 41 and a pair of curved members 42, which are respectively arranged with gaps between the adjacent intermediate members 43. Therefore, even if a size difference occurs due to the difference in thermal expansion coefficient, the end of the held member 21 is held by the pair of curved members 42 in the groove 22 formed on the curved portion 15 and the arm 16 of the upper bracket 13, thereby suppressing misalignment.

[0053] like Figures 5 to 8 As shown in FIG. 1 , in the central member 41, the intermediate member 43, and the curved member 42, the fixing portion 25 extends in the vehicle width direction by a length corresponding to the length of the engaging portion 24 in the vehicle width direction. That is, the portion of the holding member 23 extending in the vehicle width direction has an L-shaped cross section. Therefore, the bending rigidity of the holding member 23 is improved over the entire length in the vehicle width direction. As a result, the bending of the holding member 23 is suppressed, and the loosening of the deflector body 11 is suppressed.

[0054] As described above, the threaded hole 30 ( Figure 4 ), and a protrusion 46 is provided near the fixing portion 25 of the holding member 23, and a circular hole 44 and a long hole 45 are formed as positioning holes engaged with the protrusion 46. That is, the holding member 23 can be aligned with respect to the guide vane 14 by engaging the protrusion 46 with the positioning hole. As a result, the screw member 27 is easy to install the guide vane 14. In addition, since the positioning hole includes the long hole 45, the dimensional error between the upper bracket 13 and the holding member 23 can be allowed when assembling.

[0055] The above is a description of a specific embodiment, and the present invention is not limited to the above embodiment and can be implemented in a wide range of deformations. For example, in the above embodiment, as an example, the description of the deflector device 10 applied to the roof 1 of an automobile can also be widely applied to trailers, railway vehicles, etc. In addition, in the above embodiment, the arm 16 is directly forced upward by the force-applying component 18, but the force-applying component 18 can also indirectly apply force to the arm 16 by applying force upward to the deflector blade 14. In addition, the specific structure, configuration, number, material, angle, etc. of each component and part can be appropriately changed within the scope of the main purpose of the present invention. On the other hand, the various components shown in the above embodiment are not necessarily indispensable and can be appropriately selected.
