Description

  The present invention relates to a vehicle window regulator that moves a window glass of a vehicle up and down.

  In order to support the window glass, the vehicle window regulator connects two carrier plates arranged at intervals in the vehicle front-rear direction to the lower end of the window glass so as to support both sides or the vicinity of the center of the window glass. Raise and lower the window glass. In such a vehicle window regulator, an elevating cable is connected to the carrier plate, and the elevating cable is wound and fed out by the drive unit, so that the carrier plate and the window glass are integrally raised and lowered.

In such a vehicle window regulator, the window glass is raised and lowered by winding and unwinding the lifting cable, and the carrier plate, the guide rail for guiding the carrier plate, the lifting cable, the drive motor, and the lifting cable are guided. This requires parts such as a guide member to increase the number of parts.
In addition, in the above-described vehicle window regulator, it is necessary to arrange an extension mechanism using a spring or the like in order to absorb the slack due to the extension of the lifting cable, which further increases the number of parts and makes the assembly work complicated. At the same time, it is difficult to reduce costs.

  In order to solve such a problem, a rack gear attached along the moving direction of the window glass and a pinion gear meshing with the rack gear are provided, and the support member attached to the window glass is rotated by driving the pinion gear. A vehicle window regulator that moves up and down by a guide rail provided along a rack gear has been proposed (see, for example, Patent Document 1).

Therefore, the space of the door panel 11 can be used effectively.

(1-3) Friction Reduction Mechanism FIG. 3 is a cross-sectional view of the window glass and the second sash.
A glass run 72 that guides the raising and lowering of the window glass 20 is attached to the inner peripheral surface of the second sash 13. The glass run 72 has a rectangular C-shaped cross section so as to correspond to the inner peripheral surface of the second sash 13, and is disposed in the second sash 13. And from the main body 73 toward the front of the vehicle so as to sandwich the main body 73 arranged to face the surface of the window glass 20 facing the rear of the vehicle and the surface of the window glass 20 in the vehicle width direction. A pair of extended glass run edges 76 and seal lips 74 and 75 are provided on the opening side of the second sash 13 to seal between the window glass 20 and the inside of the second sash 13. . The glass run 72 is formed of a thermoplastic elastomer solid rubber, foamed rubber obtained by foaming the same, or an elastic body obtained by combining these.
The second edge 22 of the window glass 20 moves up and down along the glass run 72 in the second sash 13. At this time, the front ends of the seal lips 74 and 75 of the glass run 72 are in contact with the surface of the window glass 20, and watertightness is maintained so that water droplets do not enter the second sash 13.
In the window regulator 30 of the first embodiment, the carrier plate 31 is attached to the first edge 21 side of the window glass 20 to raise and lower the window glass 20. As a result, when the window glass 20 is raised, the window glass 20 rotates toward the center pillar 40, and friction is generated between the second edge 22 of the window glass 20 and the glass run 72 in the second sash 13. growing. In order to reduce the friction between the second sash 13 on the side of the center pillar 40 and the second edge 22 of the window glass 20, a friction reducing member 71 can be disposed in the second sash 13.

As shown in FIG. 3, the friction reducing member 71 is attached to the main body 73 of the glass run 72, and is in the second sash 13 so as to contact the outer surface of the second edge 22 of the window glass 20. It is attached in the length direction.
As the friction reducing member 71, for example, a plate-like or sheet-like member formed of a synthetic resin material having a small friction coefficient such as a fluororesin containing tetrafluoride resin or polyacetal can be used.
Thus, by arranging the friction reducing member 71 in the second sash 13, the friction between the second edge 22 which is the edge of the window glass 20 on the side of the center pillar 40 and the second sash 13 is reduced. The window glass 20 is moved smoothly on the center pillar 40 side.
It is also possible to provide a friction reducing member in the first sash 12 provided on the side opposite to the center pillar 40. In this case, the friction between the first edge portion 21 of the window glass 20 and the first sash 12 is reduced. Thus, the window glass 20 can be moved smoothly.

Moreover, it is also possible to attach the member similar to the friction reduction member 71 mentioned above to the 1st edge part 21 and the 2nd edge part 22 of the window glass 20 as a friction reduction mechanism. In this case as well, the friction between the second edge 22 of the window glass 20 and the second sash 13 and / or between the first edge 21 of the window glass and the first sash 12 is reduced as described above. And the window glass 20 can be moved smoothly.
Further, as a friction reducing mechanism, at least one rotating member such as a roller may be provided between the first edge portion 21 and the second edge portion 22 of the window glass 20 and the first sash 12 and the second sash 13. it can. In this case, it is preferable to provide a plurality of rotating members at intervals along the length direction of the second sash 13 so as to be in contact with at least the second edge 22 of the window glass 20.

(1-4) Operation of the First Embodiment In the window regulator 30 according to the first embodiment, when a switch provided on the door panel 11 or the like is operated, the drive motor 35 rotationally drives the pinion gear 34 according to the operation.
For example, when a switch for raising the window glass 20 is operated, the drive motor 35 rotates the pinion gear 34 in the clockwise direction in the drawing to move the carrier plate 31 upward along the rack gear 33. At this time, the pinion gear 34 is attached to the lower end of the window glass 20 on the first edge 21 side via the carrier plate 31, and is eccentric to the first edge 21 side with respect to the center of gravity of the window glass 20. It will be attached. Accordingly, a force that rotates toward the rear of the vehicle about its own center of gravity acts on the window glass 20. The second edge 22 of the window glass 20 presses the second sash 13 by the action of the window glass 20 trying to rotate. Accordingly, the window glass 20 slides and rises while pressing the second sash 13. As described above, the window regulator 30 is a mechanism in which the window glass 20 is moved up and down by the rack gear 33 and the pinion gear 34 without using a cable, and therefore, compared with a window regulator that moves the window glass up and down using a cable. Thus, there is no influence due to the elongation of the inner cable over time, and rattling of the window glass 20 in the vertical direction of the vehicle during ascent and descent due to aging is suppressed.
Also, usually, the window glass is not hindered from being raised and lowered between the first edge of the window glass and the first sash and between the second edge of the window glass and the second sash in consideration of mounting tolerances. A predetermined amount of space is provided in the vehicle longitudinal direction. Therefore, the window glass can be minutely rotated in the vehicle front-rear direction by the space, and the rotation of the window glass 20 due to the rotation causes rattling in the vehicle front-rear direction. However, since the second edge portion 22 of the window glass 20 moves up and down while pressing the second sash 13, the space between the second edge portion 22 of the window glass 20 and the second sash 13 is eliminated. The regulator 30 also prevents rattling in the vehicle front-rear direction when the window glass 20 is raised and lowered. Therefore, rattling in the vehicle vertical direction and the front-rear direction when the window glass 20 is raised and lowered is suppressed, and the window glass 20 can be moved smoothly.
Furthermore, since the second edge 22 of the window glass 20 moves up and down while pressing the second sash 13, the generation of the pressing force between the second edge 22 and the glass run edge 76 is alleviated. Therefore, it is possible to reduce wear of the glass run 72 with the glass run edge 76. Moreover, wear of the first sash 12 and the second sash 13 can be suppressed by reducing the pressing force of the window glass 20 on the glass run 72 in the vehicle width direction.
Further, a guide claw 53 for maintaining the meshing between the pinion gear 34 and the rack gear 33 can be provided between the rack gear 33 and the guide rail 32, and the carrier plate 31 can be arranged in the vehicle width direction by the guide claw 53. The guide rail 32 can be pressed from both directions, and rattling in the vehicle width direction can be suppressed between the guide rail 32 and the carrier plate 31. Furthermore, the member and rigidity which suppress the inclination with respect to the guide rail 32 of the carrier plate 31 for suppressing the inclination of the window glass 20 become unnecessary, and it can be set as a simple structure.

  Similarly, when the window glass is lowered, the rack gear 33 and the pinion gear 34 cause the second edge 22 of the window glass 20 to slide down while pressing the second sash 13. It is possible to suppress rattling in the front and rear of the vehicle and rattling in the vehicle vertical direction.

In the first embodiment, a rack gear 33 is provided as a fixed rack fixed to the vehicle body, and a pinion gear 34 is provided as a movable pinion gear. The pinion gear 34 meshes with a rack gear 33 that is a fixed rack and is movable with respect to the vehicle body.
Since the pinion gear 34 which is a movable pinion gear is provided on the first edge 21 side of the window glass 20, the second edge 22 of the window glass 20 slides while pressing the second sash 13.
Therefore, rattling during the raising and lowering of the window glass 20 is eliminated, and the window glass 20 can move smoothly. Note that the pinion gear 34 is connected to the window glass 20 on the first edge 21 side with respect to the second edge 22, and the second sash is leaned against the second sash 13 on the second edge 22 side. What is necessary is just to connect to the position which this window glass 20 slides up and down, pressing 13.

The first sash 12 and the second sash 13 have a rectangular C-shaped cross section, and slidably hold the first edge 21 and the second edge 22 of the window glass 20, respectively.

The window glass 20 is positioned at both ends in the front-rear direction, and has a first edge portion 21 and a second edge portion 22 that are slidably guided by the first sash 12 and the second sash 13, respectively. In the illustrated example, the edge on the side of the center pillar 40 is the second edge 22, and the edge on the opposite side of the center pillar 40 is the first edge 21. The first edge portion 21 and the second edge portion 22 are slidably held by the first sash 12 and the second sash 13 of the door panel 11, respectively, and the window glass 20 moves in the X direction that is the ascending / descending direction in the figure. It is possible.
A rack gear 81 is provided along the first edge 21 of the window glass 20. The rack gear 81 has teeth formed in a direction crossing the moving direction of the window glass 20, and is formed by, for example, adhering one formed of synthetic resin to the first edge portion 21 of the window glass 20. can do. When the window glass 20 is a transparent synthetic resin molded product, the rack gear 81 can be formed integrally with the window glass 20.

(2-2) Window Regulator FIG. 5 is an enlarged view of the window regulator.
In this embodiment, the window regulator 80 has a rack gear 81 that is a movable rack and a pinion gear 82 that is a fixed pinion gear.
As described above, the rack gear 81 is formed on the first edge portion 21 of the window glass 20 and is disposed inside the first sash 12.
The first sash 12 has an opening 91, and a part of the rack gear 81 is exposed through the opening 91.

The pinion gear 82 is rotatably supported by a bracket 92 attached to the door panel 11 and is disposed at a position where it can mesh with the rack gear 81 through the opening 91 of the first sash 12.
A drive motor 83 that drives the pinion gear 82 directly or via a reduction gear is attached to the bracket 92.
In addition, the bracket 92 is supported by pins 93 and 94, and can finely move in a direction in which the pinion gear 82 and the rack gear 81 approach and separate from each other.
The bracket 92 is urged toward the first edge 21 of the window glass 20 by an urging means 86 such as a spring.
As a result, the pinion gear 82 supported by the bracket 92 meshes with the rack gear 81 exposed through the opening 91.

  Similar to the first embodiment, it is also possible to dispose friction reducing members inside the first sash 12 and the second sash 13 as a friction reducing mechanism.

(2-3) Operation of the Second Embodiment In the window regulator 80 according to the second embodiment, when a switch provided on the door panel 11 or the like is operated, the drive motor 83 rotates the pinion gear 82 according to the operation.
For example, when a switch for lowering the window glass 20 is operated, the drive motor 35 rotates the pinion gear 34 in the clockwise direction in the drawing to lower the window glass 20 having the rack gear 81. Since the window regulator 80 does not have an elevating cable or an elevating cable extending mechanism, the window glass 20 can be moved smoothly without being shaken in the vehicle vertical direction when the window glass 20 is lowered. Moreover, when the window glass 20 descend | falls, since the 2nd edge 22 slides, pressing the 2nd sash 13 by the side of the center pillar 40, it can suppress the shakiness in the front-back direction of the window glass 20. it can.

When the switch for raising the window glass 20 is operated, the drive motor 83 rotates the pinion gear 82 counterclockwise in the drawing to raise the window glass 20 having the rack gear 81. Also in this case, since the window regulator 80 does not have an elevating cable or an elevating mechanism for the elevating cable, the window glass 20 can be smoothly moved without rattling in the vehicle vertical direction when the window glass 20 rises. .
When the window glass 20 rises, the second edge portion 22 slides while pressing the second sash 13 on the center pillar 40 side, so that rattling in the front-rear direction of the window glass 20 can be suppressed.

(3) Common Items of Embodiments The first and second embodiments have the following configurations and functions in common.
A window regulator (for example, window regulator 30, 80) includes a fixed rack or fixed pinion gear (for example, rack gear 33, pinion gear 82), a movable pinion gear or movable rack (for example, pinion gear 34, rack gear 81), and a drive unit (for example, Drive motors 35, 83). The fixed rack or fixed pinion gear (for example, the rack gear 33 and the pinion gear 82) is fixed to the vehicle body side. The movable pinion gear or the movable rack (for example, the pinion gear 34, the rack gear 81) meshes with the fixed rack or the fixed pinion gear (for example, the rack gear 33, the pinion gear 82). The drive units (for example, drive motors 35 and 83) rotate and drive a fixed pinion gear or a movable pinion gear (for example, pinion gears 82 and 34). Here, the movable pinion gear or the movable rack (for example, the pinion gear 34, the rack gear 81) is a first edge (for example, the second edge 22) of the window glass (for example, the window glass 20). The second edge (for example, the second edge 22) is connected to the first edge (21) side, and the sash (for example, the second sash 13) is driven by driving of the drive parts (for example, the drive motors 35 and 83). The movable pinion gear or the movable rack (for example, the pinion gear 34 and the rack gear 81) is driven to move up and down so that the window glass (for example, the window glass 20) slides up and down while being pressed.
The vehicle window regulator uses a movable pinion gear and a fixed rack that mesh with each other, or a fixed pinion gear and a movable rack that mesh with each other, thereby eliminating rattling when the window glass is raised and lowered. By driving up and down, the second edge portion of the window glass slides while pressing the sash, so that the friction between the window glass and the sash can be prevented from increasing.
