In the present embodiment, the ascending/descending direction corresponds to the upper/lower direction of the window regulator, and a vehicle width direction of vehicle corresponds to the front/rear direction of the window regulator. In addition, a direction orthogonal to the ascending/descending direction and the vehicle width direction is defined as the right/left direction of the window regulator.
(Configuration of the Vehicle Door)
Herein, a vehicle door D to which the window regulator 1 is attached will be explained with referring to FIG. 1 before the explanation of window regulator 1. The vehicle door D is provided to an automobile (vehicle). In the meantime, FIG. 1 shows the vehicle door D with omitting an outer panel described below.
As shown in FIG. 1, the vehicle door D includes a door main body D1, a vehicle window glass G supported to freely ascend and descend along a glass guide (not shown) of the door main body D1, a window regulator 1 that is attached to the door main body D1 to raise/lower the window glass G.
The door main body D1 includes a storing portion D11 storing the window glass G and a door sash D12 provided above the storing portion D11. The storing portion D11 includes an inner panel D13 serving as a door panel at an inside of the vehicle compartment, and an outer panel (not shown) at an outside of the vehicle compartment. A door inside space is defined between the inner panel D13 and the outer panel. As shown in FIG. 2, the window regulator 1 is attached to the inner panel D13 in the door inside space. In addition, as shown in FIG. 1, the window regulator 1 is attached with inclining to a rear side of vehicle front/rear direction to the door main body D1.
(Configuration of the Window Regulator)
As shown in FIGS. 3A to 3C, the window regulator 1 includes a guide rail 2 provided along the ascending/descending direction, a carrier plate 3 that supports the window glass G and is slidably attached to the guide rail 2, an ascending-side wire 4 (wire) and a descending-side wire 5 that pull the carrier plate 3, and ascend/descend the carrier plate 3 along the guide rail 2, a driving portion 6 that is arranged at the lower end of the guide rail 2 (one end in the ascending/descending direction) and drives the ascending-side wire 4 and the descending-side wire 5, and a pulley 7 (turnaround portion) that is arranged at an upper end of the guide rail 2 (other end in the ascending/descending direction) and turns the ascending-side wire 4 around.
In addition, as shown in FIGS. 4A to 4D, the window regulator 1 includes an ascending-side sliding bush 11 attached to a carrier plate 3 side end of the ascending-side wire 4, an ascending-side spring 12 providing tension to the ascending-side wire 4 through the ascending-side sliding bush 11, a descending-side sliding bush 13 attached to a carrier plate 3 side end of the descending-side wire 5, and a descending-side spring 14 providing tension to the ascending-side wire 4 through the descending-side sliding bush 13. That is, the window regulator 1 serves as a wire driving window regulator that ascends/descends the carrier plate 3 by using the wires 4, 5, and is a lower end rail type window regulator arranging the driving portion 6 at the lower end of the guide rail 2.
As shown in FIG. 2, the guide rail 2 is a long-ranged metal member extended along the ascending/descending direction. The upper end of the guide rail 2 is fixed to the inner panel D13, and the lower end thereof is fixed to the driving portion 6 (a drum housing 44 of the driving portion 6). In addition, the guide rail 2 is curved to protrude toward a vehicle exterior direction in the vehicle width.
As shown in FIGS. 4A to 4D, the guide rail 2 includes a flat-plate portion 21 extended in the ascending/descending direction, a right side-plate portion 22 and a left side-plate portion 23 that are stand toward a front side from right/left ends in a short end direction of the flat-plate portion 21 (a direction orthogonal to the ascending/descending direction), a right flange portion 24 extended to a right side from a front end of the right side-plate portion 22, and a left flange portion 25 extended to a left side from a front end of the left side-plate portion 23. The guide rail 2 slidably supports the carrier plate 3 by the left side-plate portion 23.
As shown in FIGS. 3A to 3C, one end of the ascending-side wire 4 is connected to a rotating drum 42 (described below) of the driving portion 6 and the other end thereof is connected to the carrier plate 3 when the ascending-side wire 4 is fed out upward and reaches to the pulley 7 and is then turned around downward by the pulley 7. In the meantime, one end of the descending-side wire 5 is connected to the rotating drum 42 of the driving portion 6 and is fed out from the driving portion 6, and the other end thereof is attached to the carrier plate 3.
In addition, an ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 from the ascending-side wire 4 is positioned on the flat-plate portion 21 of the guide rail 2 and is overlapped on the flat-plate portion 21 of the guide rail in viewed from the vehicle width direction (a rotational axis direction of the rotating drum 42). As described above, since the guide rail 2 is curved toward the vehicle width direction, the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 to push and contact a middle portion in the upper/lower direction of the flat-plate portion 21 of the guide rail 2 (see e.g., FIG. 2). Hereby, the flat-plate portion 21 of the guide rail 2 serves as a wire supporting configuration supporting the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 at the middle portion in the upper/lower direction. In the meantime, the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3 from the ascending-side wire 4 and the descending-side wire 5 are positioned at a position shifted from the guide rail 2. The ascending-side wire 4b and the descending-side wire 5 are shifted from the guide rail 2 in a right/left direction in viewed from the vehicle width direction (the rotational axis direction of the rotating drum 42).
As shown in FIGS. 4A to 4D and 5A to 5C, the carrier plate 3 is a plate-shaped member formed of resins such as polyacetal, and the carrier plate 3 is arranged to face the flat-plate portion 21 of the guide rail 2. Two right and left attaching holes 31 to attach the window glass G, a rail attaching portion 32 arranged at a center in a right/left direction of a rear surface side (back side in FIGS. 4A to 4C), an ascending-side housing portion 33 arranged at a left side of the rail attaching portion 32, a descending-side housing portion 34 arranged at a left side of ascending-side housing portion 33, a notch portion 35 avoiding the ascending-side wire 4a on the flat-plate portion 21 of the guide rail 2, which is arranged at a right side of the rail attaching portion 32 in a rear surface side, and a contacted portion 36 on which a position regulating portion 64 of the driving portion 6 is contacted, and which is arranged at a right side lower end of the notch portion 35.
The attaching holes 31 are for bolt fasting a glass holder (not shown) fixed on the window glass G. The window glass G is attached to the carrier plate 3 through the glass holder by fasting the glass holder to the attaching holes 31 by bolts.
The rail attaching portion 32 is slidably attached to the left side-plate portion 23 of the guide rail 2. That is, the rail attaching portion 32 is supported to freely ascend and descend by the left side-plate portion 23 of the guide rail 2.
As shown in FIG. 4, the ascending-side housing portion 33 houses the ascending-side sliding bush 11 and the ascending-side spring 12. Hereby, a carrier plate 3 side end of the ascending-side wire 4 is attached to the ascending-side housing portion 33 through the ascending-side sliding bush 11 and the ascending-side spring 12. In the meantime, the descending-side housing portion 34 houses the descending-side sliding bush 13 and the descending-side spring 14. Hereby, a carrier plate 3 side end of the descending-side wire 5 is attached to the descending-side housing portion 34 through the descending-side sliding bush 13 and the descending-side spring 14.
The notch portion 35 is extended in the ascending/descending direction such that the carrier plate 3 does not contact the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7. Since disjunction of the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 against the guide rail 2 is different depending on a position on the guide rail 2 in the ascending/descending direction, as shown in FIG. 4C, a depth of the notch portion 35 in the front/rear direction is a depth such that the ascending-side wire 4a does not contact the carrier plate 3 even when the carrier plate 3 is located at an upper end position of the guide rail 2 where the ascending-side wire 4a is the farthest from the guide rail 2 (when the window glass G is fully-closed).
Further, as shown in FIG. 4D, the ascending-side wire 4a located at a lower end position of the guide rail 2 where the carrier plate 3 when the window glass G is fully-opened faces is arranged to be closer to the guide rail 2 than the ascending-side wire 4a located at the upper end position of the guide rail 2 shown in FIG. 4C. It is because a wire feeding out position P1 of the rotating drum 42 is located to be closer to the guide rail 2 in the vehicle width direction than the wire feeding out position of the pulley 7.
As shown in FIGS. 6A and 6B, the pulley 7 includes a pulley main body 37 winding and turning the ascending-side wire 4 around, a pulley shaft 38 rotatably supporting the pulley main body 37.
The pulley shaft 38 is fixed on a pulley supporting portion 26 arranged on the upper end of the guide rail 2 to pass through the pulley supporting portion 26. In addition, a bolt portion 38a to be fixed to the inner panel D13 is formed at a tip end (rear end) of the pulley shaft 38. Thus, as shown in FIG. 2, the upper end of the guide rail 2 is fixed to the inner panel D13 by the pulley shaft 38.
As shown in FIGS. 7A to 8, the driving portion 6 includes a driving motor 41 having a reducer 51, which can forward/reverse rotationally drive, a rotating drum 42 rotationally driven by the driving motor 41, and a housing 43 to house the rotating drum 42 and hold the driving motor 41. The housing 43 includes a drum housing 44 that fits the lower end of the guide rail 2 and rotatably houses the rotating drum 42, and a motor housing 45 to hold the driving motor 41.
Driving portion 6 side ends of the ascending-side wire 4 and the descending-side wire 5 are connected to the rotating drum 42. The ascending-side wire 4 and the descending-side wire 5 are took up and fed out by rotating the rotating drum 42. In addition, the rotating drum 42 is configured to feed out the ascending-side wire 4 from a right-side wire feeding out position P1 and the descending-side wire 5 from a left-side wire feeding out position P2. The right-side wire feeding out position P1 of the rotating drum 42 (the wire feeding out position of the ascending-side wire 4) is overlapped with the guide rail 2 in the right/left direction (an orthogonal direction orthogonal to the ascending/descending direction). In the meantime, the left-side wire feeding out position P2 of the rotating drum 42 (the wire feeding out position of the descending-side wire 5) shifts from the guide rail 2 in the right/left direction. Hereby, only the ascending-side wire 4a fed out from the right-side wire feeding out position P1 of the rotating drum 42 to the pulley 7 from the ascending-side wire 4a fed out from the right-side wire feeding out position P1 of the rotating drum 42 and the descending-side wire 5 fed out from the left-side wire feeding out position P2 of the rotating drum 42 to the carrier plate 3 is configured to overlap the guide rail 2.
The driving motor 41 includes the reducer 51 enclosed in the motor housing 45 and rotatably attaching the rotating drum 42 to an output axis, and a yoke portion 52 (motor main body) arranged to be adjacent to a right-side of the reducer 51 and rotating the rotating drum 42 through the reducer 51.
When the driving motor 41 is forward driven, the rotating drum 42 forward rotates and the descending-side wire 5 is fed out and the ascending-side wire 4 is wound in accordance with the rotation. Hereby, the carrier plate 3 is pulled by the ascending-side wire 4 and moves in the raising direction. Thus, the window glass G attached to the carrier plate 3 ascends (ascending movement of the window glass G). In the meantime, when the driving motor 41 is reverse driven, the rotating drum 42 reverses and the ascending-side wire 4 is fed out and the descending-side wire 5 is wound in accordance with the rotation. Hereby, the carrier plate 3 is pulled by the descending-side wire 5 and moves in the lower direction. Thus, the window glass G attached to the carrier plate 3 descends (descending movement of the window glass G). Therefore, the carrier plate 3 and the window glass G are ascended/descended along the guide rail 2 by such configuration.
Two fixing holes 61 to fix the drum housing 44 to the inner panel D13 by bolts 61a, a drum housing portion 62 to house the rotating drum 42, a fitting hole 63 arranged at upper right of the drum housing portion 62 and fitting the lower end of the guide rail 2, and a position regulating portion 64 arranged at a front side of the fitting hole 63 (front side in FIG. 7A). The position regulating portion 64 regulates moving the carrier plate 3 to lower end by contacting the contacted portion 36 of the carrier plate 3 when the window glass G is fully-opened.
The fitting hole 63 fits to the lower end portion of the guide rail 2. The lower end portion of the guide rail 2 is fixed to the drum housing 44 by the fitting hole 63. Since the fitting hole 63 is arranged to the right-side wire feeding out position P1 of the rotating drum 42 housed in the drum housing portion 62 in the right/left direction (a direction orthogonal to the ascending/descending direction and the vehicle width direction), the guide rail 2 fit to the fitting hole 63 is arranged to overlap the right-side wire feeding out position P1 of the rotating drum 42 in the right/left direction. Thus, the guide rail 2 is configured to overlap the ascending-side wire 4a fed out from the right-side wire feeding out position P1 to the pulley 7 in the right/left direction. Hereby, the guide rail 2 can close to the yoke portion 52 of the driving motor 41 as possible.
The motor housing 45 includes the reducer 51 and covers an opening of the drum housing portion 62 of the drum housing 44 while rotatably attaching the output axis of the reducer 51. In addition, three fixing portions 71 to fix the motor housing 45 to the drum housing 44 is formed in the motor housing 45. In the meantime, a part of the three fixing portions 71 is arranged at a position overlapped with the guide rail 2 in the right/left direction.
Effects of the Embodiment
According to the configuration in the above embodiment, since the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 is configured to be located on the guide rail 2, it is possible to serve the guide rail 2 as a wire supporting portion to support the ascending-side wire 4a at a middle portion in the ascending/descending direction. Thus, it is possible to support the ascending-side wire 4a by the simple configuration without attaching a separate wire supporting portion. That is, it is possible to prevent the ascending-side wire 4a from contacting the inner panel D13 and prevent the occurrence of abnormal noise (such as vibration noise) when opening/closing the door.
In addition, according to the configuration in the above embodiment, since only the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 among the ascending-side wire 4a, the ascending-side wire 4b and the descending-side wire 5 is configured to be poisoned on the guide rail 2, it is possible to decrease width (width in the right/left direction) of the guide rail 2. Thus, the weight of the window regulator 1 can further reduce.
In addition, according to the configuration in the above embodiment, it is possible to prevent the occurrence of hitting sound by contacting the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3 with the guide rail 2 by locating the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7, and locating the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3 at a position shifted from the guide rail 2. That is, when a configuration that locates both the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7, and the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3 on the guide rail 2 is adopted, the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7 can constantly push and contact the guide rail 2 regardless ascending/descending position of the carrier plate 3. However, the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3 is slightly separated from the guide rail 2 in some ascending/descending position of the carrier plate 3. If the ascending-side wire 4b is slightly separated from the guide rail 2, the ascending-side wire 4b swings in the vehicle width direction and hardly contacts the guide rail 2, and thus the hitting sound occurs when opening/closing the vehicle door D. In the meantime, according to the configuration in the above embodiment, it is possible to prevent from swinging the ascending-side wire 4b in the vehicle width direction and hardly contacting the guide rail 2, and thus prevent the occurrence of hitting sound when opening/closing the vehicle door D by locating the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3 at the position shifted from the guide rail 2. That is, in the above embodiment, with the ascending-side wire 4a arranged between the driving portion 6 and the pulley 7, the abnormal noise when opening/closing the vehicle door D can be prevented by positioning the wire 4a on the guide rail 2 such that the wire 4a is pushed and contacted against the guide rail 2, and with the ascending-side wire 4b arranged between the pulley 7 and the carrier plate 3, the abnormal noise when opening/closing the vehicle door D can be prevented by positioning the wire 4b to be shifted from the guide rail 2 such that the wire 4b is disposed not to overlap the guide rail 2 when viewed in the vehicle width direction.
In addition, according to the configuration in the above embodiment, even when the carrier plate 3 moves to any positions in the ascending/descending direction, the carrier plate 3 does not contact the ascending-side wire 4a pushed and contacted on the guide rail 2 by providing the notch portion 35 to the carrier plate 3. Thus, it is possible to contact the ascending-side wire 4a to the guide rail 2 without any interferences. That is, the carrier plate 3 does not interfere when the ascending-side wire 4a pushes and contacts the guide rail 2.
Other Embodiments
Although the embodiment of the invention has been described, the invention according to claims is not to be limited to the embodiment described above. Further, please note that all combinations of the features described in the embodiment are not necessary to solve the problem of the invention. The invention can be appropriately modified and implemented without departing from the gist thereof.
For example, although the above embodiment has a configuration that partially narrows a width of the notch portion 35 by the contacted portion 36, as shown in FIG. 9A, the contacted portion 36 may be omitted. In addition, as shown in FIG. 9B, the notch portion 35 may be formed in a rectangular shape in viewed from the upper/lower direction (ascending/descending direction).
