Description

  The present invention relates to a vehicle deflector device.

  Conventionally, as a deflector device for vehicles, what was indicated, for example in patent documents 1 is known. In this vehicle deflector device, a pair of guide rails (7) are disposed at both edges in the vehicle width direction of the opening formed in the roof of the vehicle. A base member (9) is attached to each guide rail. Each base member rotatably supports the arm portions (10) on both sides in the vehicle width direction of the deflector (5) disposed at the front end portion of the opening. Thereby, a deflector can protrude on the surface of a roof part in the front-end part of an opening part.

  Here, when attaching the base member to the guide rail, the guide is made in a state where the four protrusions (9d) of the base member are aligned with the four recesses (14a) formed on the protrusions (14) of the guide rail. Assemble in the height direction of the rail and place the base member on the upper surface of the guide rail. Then, in this state, the base member is slid in the longitudinal direction in which the guide rail extends, and each protrusion (9d) enters under the protrusion. At the same time, the two protrusions (9e) of the base member are inserted into the recesses (14a, 14b) formed on the protrusion. As described above, the base member is positioned with respect to the guide rail in the longitudinal direction, the width direction, and the height direction of the guide rail.

Japanese Patent Laying-Open No. 2006-168439 (page 5, FIG. 6)

  By the way, in Patent Document 1, when the base member is attached to the guide rail, the assembly is performed in two directions, ie, the height direction and the longitudinal direction of the guide rail, and accordingly, the number of assembling steps is inevitably increased. Moreover, since it is necessary to cut out the recessed part for an assembly | attachment to a guide rail, it will be forced to increase a manufacturing man-hour for the said process. In particular, since the protrusion of the guide rail is formed at a position away from the bottom wall in the height direction, it is estimated that it is difficult to form each recess by simple pressing.

  The objective of this invention is providing the deflector apparatus for vehicles which can reduce the assembly man-hour of the base member which supports a deflector, suppressing the increase in a manufacturing man-hour.

  In order to solve the above problems, the invention described in claim 1 is provided at the front end portions of the pair of guide rails disposed at both edges in the vehicle width direction of the opening formed in the roof portion of the vehicle. In the vehicle deflector device, comprising: a base member to be worn; and a deflector supported by the both base members and capable of projecting on the surface of the roof portion, the guide rail is erected on the bottom wall and extends in the longitudinal direction. A guide piece projecting in a width direction facing each other from a pair of existing side walls, and a mounting hole that opens the bottom wall in the height direction, and the base member slides in the longitudinal direction of the guide rail. A guide groove into which both guide pieces are inserted movably, a flexible portion extending in the longitudinal direction of the guide rail and abutting against the bottom wall, and protruding from the flexible portion and fitted into the mounting hole And provided with a fitting projection to That.

  According to this configuration, the base member is inserted in the guide grooves into the guide grooves and slid in the longitudinal direction of the guide rail, thereby causing the base rail to move in the width direction and the height direction. Positioned. At this time, the flexible portion moves in the longitudinal direction of the guide rail in a state in which the fitting protrusion is elastically deformed so as to be lifted from the bottom wall by contacting the bottom wall. When the fitting protrusion reaches the attachment hole and fits into the attachment hole, the flexible portion is elastically restored and abuts against the bottom wall. And the said base member is positioned in the longitudinal direction with respect to the said guide rail by the said fitting protrusion which fits in the said attachment hole. As described above, since the base member can be attached and fixed to the guide rail only by moving the base member in one direction which is the longitudinal direction of the guide rail, the number of assembling steps of the base member can be reduced. it can. In addition, since the processing on the guide rail side is only perforation of the mounting hole that opens the bottom wall in the height direction, the mounting hole is usually combined with press processing that is normally necessary as post-processing of the guide rail. And an increase in the number of manufacturing steps can be suppressed.

The gist of the invention according to claim 2 is that, in the vehicle deflector device according to claim 1, the flexible portion is shaped so as to be displaced downward toward the tip.
According to this configuration, the flexible portion is formed so as to be displaced downward toward the tip, so that the tip is biased downward by contact (pressure contact) with the bottom wall. An urging force, that is, an urging force on the side of fitting the fitting protrusion into the mounting hole is generated. Thereby, it can prevent that the said fitting protrusion falls out of the said attachment hole.

  According to a third aspect of the present invention, in the vehicle deflector device according to the first or second aspect of the present invention, at least one of the upper holder portion and the lower holder portion that sandwich the guide pieces of the respective guide grooves in the vertical direction protrudes from the bay. The gist of the present invention is that a contact portion that contacts the guide piece is provided.

  According to the same configuration, the abutment portion is protruded from the upper holder portion or the lower holder portion and abuts on the guide piece. Therefore, the guide piece is opposed to the guide groove by the abutment portion. Inserted with line contact. Therefore, the base member can be firmly positioned in the height direction of the guide rail while the guide piece can be easily inserted into the guide groove.

  In the present invention, it is possible to provide a vehicle deflector device capable of reducing the number of assembling steps of a base member that supports the deflector while suppressing an increase in the number of manufacturing steps.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 5 is a schematic view of a sunroof device 11 mounted on a roof 10 as a roof portion of a vehicle such as an automobile as viewed obliquely from above. As shown in the figure, the roof 10 has a substantially square roof opening 10a. The sunroof device 11 includes a deflector 12 disposed and supported on the front edge of the roof opening 10a, and moves in the vehicle front-rear direction to open and close the roof opening 10a. A rectangular movable panel 13 is provided.

  The deflector 12 is attached so as to be able to perform a so-called tilt-up operation in which the front part moves upward by rotating around the rear part. When the movable panel 13 is opened, the deflector 12 is released from the movable panel 13 side and tilts up, and protrudes above the top surface of the roof 10 (deployed state). Alternatively, the deflector 12 is pressed from the movable panel 13 side with the closing operation of the movable panel 13 and fits below the upper surface of the roof 10 (stored 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.

  The movable panel 13 is attached so as to be capable of a tilt-up operation in which the rear part moves upward by rotating around the front part and a sliding action in the vehicle front-rear direction. In the opening / closing operation of the movable panel 12, a so-called outer sliding type is employed in which the sliding operation is performed in the tilted-up state.

Next, the deflector 12 and its support structure will be further described.
As shown in FIG.1 and FIG.2, the sunroof apparatus 11 is provided with the guide rail 14 provided in the vehicle width direction edge part of the roof opening part 10a. The guide rail 14 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. An appropriate drive mechanism (not shown) for opening and closing the movable panel 13 slides on the guide rail 14.

  Further, the guide rail 14 has a rail portion 16 having a substantially C-shaped cross section that opens upward in the vehicle at a position in the vehicle width direction different from the sliding position of the drive mechanism. Specifically, in the vehicle width direction, it is positioned between a link guide portion 14a that slidably supports the drive mechanism and a shade guide portion 14b that slidably supports a sunshade panel (not shown). That is, the rail portion 16 has a bottom wall 16a that forms part of the bottom wall of the guide rail 14 and is continuous with the bottom wall of the link guide portion 14a and the bottom wall of the shade guide portion 14b, and the bottom wall 16a. And a pair of guide pieces 16d protruding from the side walls 16b, 16c to the opposite sides in the vehicle width direction. Needless to say, the bottom wall 16 a, the side walls 16 b and 16 c, and the guide piece 16 d extend in the longitudinal direction of the guide rail 14. Further, as shown in FIG. 3, a substantially circular mounting hole 17 that opens the bottom wall 16 a in the height direction is formed in the front end portion of the rail portion 16.

  As shown in FIG. 1, a resin base member 31 constituting the hinge portion of the deflector 12 is attached and fixed to the front end portion of the rail portion 16. That is, the base member 31 has a pair of holder portions 32 and 33 arranged in parallel in the vehicle longitudinal direction. The front holder part 32 is formed longer in the front-rear direction than the rear holder part 33. As shown in FIG. 2, the holder portions 32 and 33 are provided on the upper side of the guide piece 16d and protruded on both sides in the vehicle width direction and on the lower side of the guide piece 16d and protruded on both sides in the vehicle width direction. It has side holder portions 32b and 33b and is formed in a substantially H-shaped cross section. The holder portions 32 and 33 sandwich the guide pieces 16d in the vertical direction between the upper holder portions 32a and 33a and the lower holder portions 32b and 33b. The upper holder portions 32a and 33a and the lower holder portions 32b and 33b arranged in parallel in the vehicle height direction form a guide groove G. In addition, as shown in an enlarged view in FIG. 4, the holder portions 32 and 33 have substantially arcuate contact portions 32c and 33c that protrude upward from the lower holder portions 32b and 33b, respectively. These abutting portions 32c and 33c abut on guide pieces 16d sandwiched between the upper holder portions 32a and 33a and the lower holder portions 32b and 33b. This is because the holding of the rail portion 16 (guide piece 16d) by the holder portions 32 and 33 is concentrated at the two front and rear points to suppress the rattling of the base member 31.

  Further, as shown in FIG. 1, the base member 31 is a pair of mutually parallel pairs erected upward from both ends in the width direction of the holder portions 32, 33 in a mode of bridging the holder portions 32, 33 in the vehicle front-rear direction. In addition to having a connecting wall 34, it has a substantially cylindrical hinge pin 35 that connects between the connecting walls 34 at an intermediate position between the holder portions 32 and 33. The axis of the hinge pin 35 extends in the vehicle width direction (width direction of the rail portion 16). An arc-shaped bearing 32d (see FIG. 3) centering on the hinge pin 35 is formed at the rear end of the holder 32 (upper holder 32a).

  Furthermore, the base member 31 has a tongue-like flexible portion 36 extending from the front end of the front lower holder portion 32b to the front side, and extends from the rear end of the rear lower holder portion 33b to the rear side. It has a tongue-shaped flexible portion 37 that protrudes. As shown in an enlarged view in FIG. 4, the flexible portions 36 and 37 are formed so as to be displaced downward toward the tip. The rear flexible portion 37 is provided with a substantially cylindrical fitting projection 38 (see FIG. 3) that is fitted into the mounting hole 17 so as to protrude downward.

  In such a configuration, when the base member 31 is assembled to the rail portion 16, both guide grooves G are placed in the guide groove G with the flexible portion 37 facing the front side of the rail portion 16 as shown in FIG. The guide piece 16d is inserted and slid in the front-rear direction (longitudinal direction of the rail portion 16). At this time, the flexible portion 37 moves in the longitudinal direction of the rail portion 16 in a state of being elastically deformed so as to be lifted from the bottom wall 16a by the fitting projection 38 coming into contact with the bottom wall 16a. When the fitting protrusion 38 reaches the attachment hole 17 and fits into the attachment hole 17, the flexible portion 37 is elastically restored and abuts against the bottom wall 16a. The flexible portion 37 is shaped so as to be displaced downward as it goes to the tip, so that the urging force on the side that urges the tip downward by contact (pressure contact) with the bottom wall 16a, that is, A biasing force is generated on the side where the fitting protrusion 38 is fitted into the mounting hole 17. Similarly, the flexible portion 36 also generates a biasing force on the side that biases the tip downward by contact (pressure contact) with the bottom wall 16a. The base member 31 is positioned in the longitudinal direction with respect to the rail portion 16 (guide rail 14) by the fitting protrusion 38 that is fitted into the mounting hole 17. Needless to say, the positioning of the base member 31 in the width direction and the height direction with respect to the rail portion 16 (guide rail 14) is realized by inserting and sliding the guide pieces 16d in both guide grooves G.

  As shown in FIG. 3, the deflector 12 has an arm part 41 extending in the vehicle front-rear direction at each end in the vehicle width direction, and is supported by the base member 31 at the arm part 41. That is, a groove portion 42 is formed at the rear end portion of the arm portion 41 through which the hinge pin 35 of the base member 31 is inserted so as to be relatively rotatable. The groove 42 has a substantially U shape in a side view so that the hinge pin 35 can be inserted in a radial direction centered on the axis of the hinge pin 35 by opening to the rear side of the vehicle. Further, at the rear end portion of each arm portion 41, an arc shape is arranged on the vehicle rear side of the bearing portion 32d of the base member 31 and slidably contacts the bearing portion 32d as the arm portion 41 around the hinge pin 35 rotates. A sliding contact surface 43 is formed.

  Accordingly, the rear end portion of each arm portion 41 is inserted between the connecting walls 34 so that the groove portion 42 is inserted into the hinge pin 35 so as to be relatively rotatable, and the sliding contact surface 43 is in sliding contact with the bearing portion 32d. The base member 31 is assembled so as to be sandwiched between the bearing portions 32d in the vehicle front-rear direction. In addition, the arm part 41 (deflector 12) attached to the base member 31 is restricted in its rotation range to a constant amount when mounted on the roof 10. Thereby, the position shift of each arm part 41 (deflector 12) in the vehicle front-rear direction is suppressed. Moreover, the groove part 42 is extended to the upper direction and the downward direction of the hinge pin 35, and the position shift of the vehicle up-down direction of each arm part 41 (deflector 12) is suppressed collectively. Furthermore, the rear end portion of each arm portion 41 is sandwiched between the connecting walls 34 in the vehicle width direction, and positional deviation in the vehicle width direction is also suppressed.

  In addition, each arm part 41 (deflector 12) is always urged | biased by the side which the front-end part raises with respect to the rear-end part, ie, the side where the deflector 12 protrudes on the surface of the roof 10, with the urging means which is not shown in figure. . Thereby, the deflector 12 released from the movable panel 13 side with the opening operation of the movable panel 13 is urged by the urging means to be in a deployed state.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In this embodiment, the base member 31 inserts both guide pieces 16d into the both guide grooves G and slides in the longitudinal direction of the guide rail 14, whereby the width and height of the guide member 14 are increased. Positioned in the vertical direction. At this time, the flexible portion 37 moves in the longitudinal direction of the guide rail 14 in a state of being elastically deformed so as to be lifted from the bottom wall 16a by the fitting projection 38 coming into contact with the bottom wall 16a. When the fitting protrusion 38 reaches the attachment hole 17 and fits into the attachment hole 17, the flexible portion 37 is elastically restored and abuts against the bottom wall 16a. The base member 31 is positioned in the longitudinal direction with respect to the guide rail 14 by a fitting protrusion 38 that is fitted into the mounting hole 17. Thus, since the base member 31 can be attached and fixed to the guide rail 14 only by moving the base member 31 in one direction which is the longitudinal direction of the guide rail 14, the number of steps for assembling the base member 31 can be reduced. it can. Further, since the processing on the side of the guide rail 14 (rail portion 16) is only the drilling of the mounting hole 17 that opens the bottom wall 16a in the height direction, press processing that is usually necessary as post-processing of the guide rail 14 is performed. In addition, the attachment hole 17 can be provided, and an increase in the number of manufacturing steps can be suppressed.

  (2) In the present embodiment, the flexible portion 37 is shaped so as to be displaced downward toward the tip, and thereby urges the tip downward by contact (pressure contact) with the bottom wall 16a. A biasing force on the side, that is, a biasing force on the side where the fitting protrusion 38 is fitted into the mounting hole 17 is generated. Thereby, it is possible to prevent the fitting protrusion 38 from falling off the mounting hole 17.

  (3) In the present embodiment, the contact portions 32c and 33c are protruded from the lower holder portions 32b and 33b and come into contact with the guide piece 16d. Therefore, the guide piece 16d is guided by the contact portions 32c and 33c. Inserted into the groove G by line contact. Accordingly, the base member 31 can be firmly positioned in the height direction of the guide rail 14 (rail portion 16) while the guide piece 16d can be easily inserted into the guide groove G.

(4) In the present embodiment, when the deflector 12 rotates around the hinge pin 35, the sliding contact surface 43 is in sliding contact with the bearing portion 32d, so that the rotation can be performed more stably.
(5) In the present embodiment, the deflector 12 is rotatably supported by the hinge pin 35 by inserting the hinge pin 35 into the groove portion 42 in the radial direction around the hinge pin 35. Therefore, the deflector 12 can be easily assembled to the base member 31.

In addition, you may change the said embodiment as follows.
In the above embodiment, the arm part 41 is rotatably supported by inserting the hinge pin 35 provided on the base member 31 into the rear end part (groove part 42) of the arm part 41. A hinge pin provided in the portion (groove portion 42) may be inserted through the base member 31 (both connecting walls 34) to support the arm portion 41 in a freely rotatable manner.

  In the above-described embodiment, the substantially arcuate contact portion that contacts the guide piece 16d is provided in the upper holder portions 32a and 33a instead of the lower holder portions 32b and 33b or in addition to the lower holder portions 32b and 33b. May be.
