Description

  The present invention relates to a vehicle door window regulator structure.

  FIG. 5 shows a door panel 1 of a cab overtrack, and the door panel 1 incorporates a window regulator 11 that moves the window glass 3 up and down. In the window regulator 11, a single rail 12 is vertically moved from a position immediately below the lower edge 2a of the window 2 to the vicinity of the lower end 1a of the door panel 1 at the approximate center of the door panel 1 (in the vicinity of the vertical position passing through the approximate center of gravity of the window glass 3). The carrier plate 13 is mounted on the rail 12 so as to be movable up and down, and the lower end center portion of the window glass 3 is fixed. Pulleys 14 and 15 are provided at substantially the center positions of the upper and lower ends of the rail 12. A stopper rubber 16 for locking the carrier plate 13 is provided at the lower end of the rail 12 at a position near the front side of the pulley 15.

  The wire 17 is wound several times around a pulley 19 of a drive motor assembly 18 disposed at a front position of the rail 12, and passes through the center of the rail 12 (approximately the center of gravity of the window glass 3) via the upper and lower pulleys 14 and 15. The both ends are fixed to the center portion of the carrier plate 13. The carrier plate 13 is moved up and down by the wire 17 in accordance with the rotation of the drive motor assembly 18, and the glass slide member is provided in which the window glass 3 is provided along the front edge portion, the upper edge portion, and the rear edge portion of the window 2. The window 2 is opened and closed by moving up and down along the run channel 4 serving as a seal member. The drive motor assembly 18 stops when the upper end of the window glass 3 abuts against the upper edge 4 b of the run channel 4 to fully close the window 2, and the stopper rubber provided with the lower end of the carrier plate 13 at the lower end of the rail 12. When it hits 16, it stops and fully opens the window 2.

As a window regulator, there is a structure in which a part of a module plate mounted on a door panel constituting a vehicle body is cut and raised to integrally form a guide rail, and a carrier to which a window glass is fixed is movably supported along the guide rail. Yes (see, for example, Patent Document 1). The structure of this window regulator is the same as that of the window regulator 11 shown in FIG. 5 except that the guide rail is integrally formed on the module plate.
JP 2001-130253 A

  As described above, in the wire type regulator that holds the carrier plate 13 by the single rail 12 so as to be movable up and down, the clearance of the sliding portion (fitting portion) between the rail 12 and the carrier plate 13 is the window glass 3. As the carrier plate 13 supports the lower end of the window glass 3, the play increases as the terminal plate rises. On the other hand, the carrier plate 13 also slides between the window glass 3 and the run channel 4 when moving up and down. Since the gap exists so as to be easy, the window glass 3 may be inclined forward or backward, and the front or rear corner may hit the front edge 4a or the rear edge 4c of the run channel 4 in some cases.

  The rubber surface of the run channel 4 is coated with urethane, silicon, or the like on the rubber surface to reduce the frictional resistance so that the wind glass 3 can slide easily. When the operation of rubbing 4 is repeated, the coating is worn away and comes into direct contact with the rubber member, so that the friction becomes so great that the window glass 3 cannot be closed.

Further, when the lower end of the carrier plate 13 descends window glass 3 abuts against the stopper rubber 16, the carrier plate for the stopper rubber 16 are arranged offset in front of the wire 17 13, the stopper rubber 16 a front in locked, becomes the center portion is pulled downward by the wire 17, the stronger the contact of the rear edge 4c of the run channel 4 Oite window glass 3 to the bottom dead center and inclined rearward, wear And the same problems as described above occur.

  If the stopper rubber 16 is disposed at the rear position of the wire 17, the above-mentioned problems can be solved, but it is difficult in terms of structure. That is, in the door panel 1 of the cab-over type vehicle as shown in FIG. 5, the gap between the lower end of the rail 12 and the lower end portion 1a is greatly cut out. However, it is difficult to dispose the stopper rubber 16.

Further, in order to reduce the backlash between the rail 12 and the carrier plate 13, the vertical movement of the window glass 3 (effective stroke) is reduced by increasing the vertical width of the carrier plate 13 and increasing the fitting length of the sliding portion. As a result, the window glass 3 cannot be completely stored in the door panel 1 and the window 2 cannot be fully opened. The window regulator disclosed in Patent Document 1 has the same problem as described above.

  The present invention has been made in view of the above-described points, and the fitting length of the sliding portion between the rail and the carrier plate is increased without sacrificing the effective stroke of the window glass, and further, the carrier plate at the bottom dead center. An object of the present invention is to provide a door window regulator structure which prevents the inclination of the door.

In order to achieve the above object, according to the present invention, one rail provided vertically below a window of a door panel of a vehicle, and both front and rear edges of the rail are mounted to be movable up and down. A carrier plate that supports the lower end of the window glass, pulleys arranged near the upper and lower ends of the rail, wires fixed to the carrier plate at both ends and wound around the upper and lower pulleys, and driving the wires Then, in the door window regulator structure comprising driving means for raising and lowering the carrier plate to open and close the window glass, and a stopper member that contacts the carrier plate and stops the carrier plate from descending , the rail has a wide width. and are the widely set the spacing of the front and rear edges of the carrier plate engages with the, the upper one of the upper and lower pulley The pulley is offset from the center of the rail to the rear side, the lower pulley is offset from the center of the rail to the front side, and the stopper member is provided near the rear side of the lower pulley. The configuration is as follows .

According to a second aspect of the present invention, in the door window regulator structure according to the first aspect of the present invention, the rail has a structure in which a plurality of holes are provided at appropriate intervals along the longitudinal direction substantially at the center in the width direction. .

  According to the first aspect of the present invention, the rail is wide and the distance between the front edge portion and the rear edge portion is set wide, so that backlash in the front-rear direction is satisfactorily suppressed when the carrier plate moves up and down. Thus, it is possible to move up and down smoothly, and the backlash of the window glass can be greatly reduced without increasing the operating resistance (sliding resistance). Accordingly, the durability of the run channel that houses the peripheral edge of the window glass is also improved.

In addition, by arranging the upper and lower pulleys offset from the center of the rail, it is possible to increase the fitting length of the carrier plate without sacrificing the effective stroke, and the window can be opened greatly even in a cab-over type vehicle. It becomes possible. In addition, the upper pulley is offset from the center of the rail to the rear side, and the lower pulley is offset from the center of the rail to the front side. When applied to a door panel that is opened obliquely upward, an effective stroke of the rail can be easily ensured. Therefore, the window 2 can be greatly opened even in a cab-over type vehicle. Further, since the placing stopper members of the carrier plate immediately after side of the lower pulley, the posture of the window glass is stabilized at the bottom dead center of the carrier plate, the inclination of the rear side of the window glass can be prevented The

According to the invention of claim 2 , it is possible to reduce the weight of the rail by providing a plurality of holes along the longitudinal direction at substantially the center in the width direction of the rail so that the weight of the rail can be reduced. Can be reduced in weight.

  The front edge portion 22a projects vertically in front of the concave strip portion 22c, and the rear edge portion 22b is doubled by folding the side wall of the concave strip portion 22f outward. The rail 22 has a front edge portion 22 a and a rear edge portion 22 b which are locking claws for locking with the carrier plate 25 and a sliding portion with the rail 22. Thereby, the space | interval of the front edge part 22a as a latching claw and the rear edge part 22b can be widened. As shown in FIG. 2, a plurality of long holes 22h are provided along the longitudinal direction at intervals in the wide recess 22e at the center of the rail 22. These long holes 22h are for reducing the weight of the rail 22. In FIG. 4, the right side is the front side of the vehicle and the lower side is the outside of the vehicle.

  Returning to FIG. 2, the rail 22 is cut out from the front edge portion 22a to a substantially half position of the concave portion 22g in order to avoid interference with the upper pulley 31 whose upper end 22i will be described later, and the rear side of the concave portion 22g. The substantially half and the rear edge portion 22b extend upward to a predetermined length, and the lower end 22j is flat (horizontal). The rail 22 is integrally formed of a metal plate (iron plate). The rail 22 is firmly fixed to the door panel with bolts at both upper and lower ends by brackets 23 and 24, respectively.

  As shown in FIGS. 2 to 4, the carrier plate 25 includes a plate main body 26 and a sliding member 27 provided on the plate main body 26 and slidably engaged with the front edge portion 22 a and the rear edge portion 22 b of the rail 22. , 28, 29. The plate body 26 is wider than the rail 22, the upper end is inclined obliquely upward from the front side toward the rear side, and the rear portion 26 a corresponding to the rear edge portion 22 b of the rail 22 forms a trapezoidal shape upward. It protrudes and the bottom is flat (horizontal). Further, mounting holes 26b and 26c for fixing the lower end portion of the window glass 3 are provided at the front and rear positions of the upper portion of the plate body 26, and the peripheral edge portions 26b 'and 26c' are arranged outside as shown in FIG. The window glass 3 is swelled and can be satisfactorily attached. In FIG. 3, the right side is the front side of the vehicle as in FIG. In FIG. 3, the rail 22 is indicated by a two-dot chain line for easy understanding.

  The sliding member 27 is provided at a front side position of the plate body 26 from a substantially half height position to the vicinity of the lower end, and is fitted into the front edge portion 22a of the rail 22 so as to be slidable and non-deviable. Convex grooves 27a and ridges 27b that are slidably fitted to the recesses 22c of the rails 22 are formed (FIG. 4). Further, as shown in FIG. 3, the sliding member 27 is provided with a stopper portion 27c that slightly bulges downward from the lower end of the plate body 26 and comes into contact with a stopper member 40 (FIG. 2) described later.

  The sliding members 28 and 29 are provided between the trapezoidal rear part 26a of the plate body 26 and the vicinity of the lower end with a slight gap in the vertical direction. The sliding member 28 is provided with a fitting groove 28a (FIG. 4) in which the rear edge portion 22b of the rail 22 is slidably fitted and locked so as not to deviate. The sliding member 29 has a protruding groove that slidably fits with a fitting groove 29a that the rear edge 22b of the rail 22 is slidably fitted and locked so as not to deviate and a groove 22g of the rail 22. A portion 29b is formed. These sliding members 27 to 29 are integrally formed with the plate body 26 by a resin member.

  The carrier plate 25 is fitted and mounted from, for example, the upper end of the rail 22 as shown in FIG. As a result, the carrier plate 25 has a front portion at the front edge portion (locking claw) 22a of the rail 22 by the sliding member 27 and a rear portion at the rear edge portion (locking claw) of the rail 22 by the sliding members 28 and 29. 22b is slidably fitted and locked in a total of three locations, two at the top and two at the top and bottom, so that backlash in the front-rear direction during elevation is greatly suppressed.

  Returning to FIG. 2, the upper pulley 31 is disposed in the vicinity of the upper end of the rail 22 and in the vicinity of the front end of the recess 22 g that is offset upward from the center of the rail 22 and extends upward, and is freely rotatable on the bracket 23. Is pivotally supported. That is, the upper pulley 31 is arranged offset from the center of the rail 22 to the rear side in accordance with the lower edge portion 2a inclined obliquely upward from the front side to the rear side of the window 2 shown in FIG. The lower pulley 32 is disposed near the lower end of the rail 22 and offset from the center of the rail 22 to the front side, and is rotatably supported by the bracket 24. The offset amounts of the upper and lower pulleys 31 and 32 from the center of the rail 22 are the same.

  In this manner, the upper pulley 31 is disposed on the rear side of the rail 22, and the lower pulley 32 is disposed on the front side of the rail 22. Thus, by arranging the upper and lower pulleys 31 and 32 offset from the center of the rail 22 to the rear side and the front side, the carrier plate 25 can be fitted without sacrificing the length of the rail 22, that is, the effective stroke. It is possible to increase the length.

In the above embodiment, the upper pulley 31 is offset from the center of the rail 22 to the rear side according to the lower edge portion 2a inclined obliquely upward from the front side to the rear side of the window 2 shown in FIG. However, the present invention is not limited to this, and it is needless to say that the present invention can also be applied when the lower edge 2a of the window 2 is horizontal.
As shown in FIG. 2, the drive motor assembly 35 is disposed at a predetermined position on the front side of the rail 22, and a pulley 36 is attached to the output shaft. The wire 37 is wound around the pulley 35 a plurality of times, and one side 37a is hung on the upper pulley 31 and hangs down from the approximate center position of the rear recess 22g of the rail 22 as shown in FIG. 37 c is fixed to the convex strip portion 29 b of the sliding member 29, and the other side 37 b is hooked on the lower pulley 32, and the substantially center position of the concave strip portion 22 c on the front side of the rail 22 extends vertically upward. As shown in FIG. 3, the tip 37 d is fixed to the ridge 27 b of the sliding member 27. One end of each of the outer tubes 38, 38 of the wire 37 is fixed in the vicinity of the pulley 37, and the other end is fixed in the vicinity of the pulleys 31, 32.

  As shown in FIG. 2, the stopper rubber 40 as a stopper member is provided at the lower end of the bracket 24 that supports the lower end of the rail 22 at a position near the rear side of the lower pulley 32. The stopper rubber 40 can be disposed immediately behind the pulley 32 by disposing the lower pulley 32 offset to the front side of the rail 22. Further, the stopper rubber 40 can be disposed in a wide gap between the lower end of the rail 22 and the lower end portion 1a of the door panel 1, which is advantageous in terms of layout. The stopper rubber 40 is provided to face the stopper portion 27c (FIG. 3) provided at the lower end of the sliding member 27 of the carrier plate 25, and the bottom dead center of the carrier plate 25 as indicated by a two-dot chain line. Then, the stopper portion 27c is brought into contact with each other to stop the lowering of the carrier plate 25.

The operation will be described below.
2, when the drive motor assembly 35 operates and the pulley 36 rotates in the clockwise direction indicated by the arrow C, the carrier plate 25 rises accordingly, and the carrier plate 25 rises to the upper end position indicated by the two-dot chain line 25 ′. The upper end of the window glass 3 shown abuts against the upper edge 4b of the run channel 4 and stops. Thereby, the window 2 is fully closed. When the pulley 36 rotates in the counterclockwise direction indicated by the arrow CC, the carrier plate 25 descends accordingly, and when the bottom dead center indicated by the two-dot chain line 25 "is reached, the stopper portion 27c of the carrier plate 25 becomes the stopper rubber. It stops at the end of 40. Thereby, the window 2 is fully opened, and a hitting sound at the bottom dead center of the carrier plate 25 can be prevented by using a rubber member as a stopper member.

  The rail 22 is made wide so that a gap between the front edge (locking claw) 22a and the rear edge (locking claw) 22b is set wide. The rear portion of the rail 22 is slidably fitted and locked to the rear edge portion 22b of the rail 22 at a total of three locations, upper and lower, by the sliding members 28 and 29 on the front edge portion 22a of the rail 22. Further, the sliding member 27 The protrusions 27b of the rail 22 and the protrusions 29b of the sliding member 29 are slidably fitted to the recesses 22g of the rail 22 so that the rail 22 is moved up and down. Sometimes back-and-forth movement is extremely well suppressed and can be moved up and down smoothly.

  Further, the carrier plate 25 is engaged with the stopper rubber 40 at a position behind and near the wire 37 when the front portion is pulled downward by the wire 37 at the bottom dead center position indicated by a two-dot chain line 25 ″ in FIG. By being stopped, the attitude of the windshield 3 at the bottom dead center is stabilized, and tilting to the rear side is prevented, whereby the upper part 3c ′ of the rear end 3c of the windshield 3 shown in FIG. 4 can be reduced without increasing the sliding resistance (friction resistance) with respect to the rear edge 4c of the windshield 4, and the window glass 3 can be raised and lowered smoothly. Durability is improved.

  Further, as shown in FIG. 1, the upper pulley 31 is moved from the center of the rail 22 to the rear side in accordance with the inclination of the lower edge portion 2a inclined obliquely upward from the front side to the rear side of the window 2, and the lower pulley. By arranging 32 to be offset from the center of the rail 22 to the front side, an effective stroke can be secured and the window 2 can be opened widely. This is particularly effective when the door panel of a cab-over type vehicle is located above the front wheel, and the lower end 1a is greatly cut away, making it difficult to keep a sufficient distance from the lower edge 2a of the window 2.
