Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic window regulator that raises and lowers a window glass disposed between an inner panel and an outer panel of a door body.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, it has been well known that a window regulator for raising and lowering a window glass is attached to a side door that can be opened and closed on a side portion of a vehicle body or a back door that can be opened and closed on a rear portion of a vehicle body. As such a window regulator, a gear fixed to a base plate fixed to the inner panel of the door body is fixedly supported, and a gear that engages with a pinion fixed to the output shaft of the motor is attached to a lift arm pivotally supported on the base plate. A type of window that is fixed and rocks the lift arm by the operation of the motor, and moves the tip of the lift arm horizontally with respect to the window glass support member that supports the window glass, thereby moving the window glass up and down. Regulators are known.
[0003]
In this type of conventional window regulator, all of its components are arranged in the space between the inner panel and the outer panel of the door body, and therefore the motor is also accommodated in this space. At that time, the upper part of the space between the inner panel and the outer panel is opened so that the window glass can be raised and lowered. Accordingly, since rainwater enters the space from the opened upper opening, it is necessary to waterproof the motor and electrical components related to the motor. However, the motor subjected to the waterproofing process as described above has a high cost, and thus cannot avoid the disadvantage that the manufacturing cost of the whole window regulator increases.
[0004]
The above-mentioned pinion and the gear meshing therewith are also arranged in the space between the inner panel and the outer panel, but when dust enters from the upper opening of the space, this enters between the pinion and the gear, thereby Wear of the gear and the gear is accelerated, and the life of these parts may be shortened.
[0005]
In order to prevent the occurrence of the above-described problem, it is conceivable that the motor, the pinion, and the gear meshing with the motor, the pinion, and the gear meshing with the motor, the pinion, and the gear are arranged on the vehicle interior side rather than the inner panel. In this way, rain water and dust do not adhere to the motor, pinion, or gear, and the above-mentioned drawbacks can be removed.
[0006]
However, in the conventional window regulator, since the gear and the lift arm are integrally fixed by welding or the like, the gear cannot be disposed outside the space. Therefore, the motor and the pinion are disposed between the inner panel and the outer panel. It could not be placed outside the space. Since the lift arm is an element that raises and lowers the window glass support member while swinging, the lift arm cannot be disposed outside the space between the inner panel and the outer panel, and the gear is integrally fixed to the lift arm. Therefore, this gear could not be arranged outside the space.
[0007]
[Problems to be solved by the invention]
The present invention has been made on the basis of the above-described novel recognition, and the object of the present invention is that rainwater and dust entering the space between the inner panel and the outer panel adhere to the motor, pinion and gear. An object of the present invention is to provide a window regulator for an automobile that can prevent this from occurring, thereby extending its life and reducing the cost of the motor.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a window regulator for an automobile that raises and lowers a window glass disposed between an inner panel and an outer panel of a door body, and is disposed so as to close a hole formed in the inner panel. A base plate fixed to the inner panel; a motor positioned on the vehicle interior side relative to the base plate; and a motor fixedly supported on the base plate; positioned on the vehicle interior side relative to the base plate; and on an output shaft of the motor A pinion that is fixed and rotationally driven by the motor, passes through the base plate, extends from the space between the inner panel and the outer panel to the vehicle interior side of the base plate, and is rotatably supported by the base plate. It is located in the vehicle interior side of the pivot and the base plate, and A gear fixed to the end of the pivot on the vehicle interior side, meshed with the pinion and driven to rotate about the central axis of the pivot by the rotation of the pinion, and disposed in the space, and on the space side of the pivot A base end is fixed to the end of the lift, and a pivot arm swings around its central axis by rotation of the pivot, and is disposed in the space and supports a lower portion of the window glass. A window regulator for an automobile is provided, comprising a window glass support member that is assembled such that the free end side thereof is movable in a substantially horizontal direction (claim 1).
[0009]
In that case, it is advantageous to provide a seal member for sealing between the outer peripheral surface of the pivot and the support hole of the base plate in which the pivot is rotatably fitted (Claim 2).

[0031]
In order to raise and lower the window glass 6 by the window regulator 7 configured as described above, first, an occupant in the vehicle interior operates a switch (not shown) provided in the vehicle to operate the motor 11. As a result, the pinion 13 rotates, and the gear 17 and the pivot 14 engaged with the pinion 13 rotate around the central axis of the pivot 14. As a result, the lift arm 16 that is integrally fixed to the gear 17 via the pivot 14 swings around the central axis of the pivot 14 in the direction indicated by the arrow B in FIG. Accordingly, the equalizer arm 21 pivotally attached to the lift arm 16 swings in the arrow C direction. At this time, the sliders 20, 25, and 27 attached to the lift arm 16 and the equalizer arm 21, respectively, are guided in the guide slots 19, 24, and 26 formed in the window glass support member 18 and the guide plate 22, respectively, in the horizontal direction. Moving. As a result, the window glass 6 moves up and down together with the window glass support member 18, and the window glass 6 moves up and down in the direction of arrow A while drawing a predetermined trajectory guided by the window frame 3. At this time, since the window glass 6 is supported by the lift arm 16 and the equalizer arm 21 via the window glass support member 18, the window glass 6 can be moved up and down in a stable state, but even if the equalizer arm 21 is omitted, It is possible to raise and lower the window glass 6.
[0032]
As mentioned above, the window glass 6 can be raised and lowered without any trouble by the illustrated window regulator 7, but this point is not different from the conventional window regulator of this type. The difference from the conventional window regulator is that the motor 11, the pinion 13 and the gear 17 are not in the space S between the inner panel 5 and the outer panel 4 but on the vehicle interior side with respect to the base plate 9 as described above. It is a point arranged in.
[0033]
With this configuration, even if rainwater or dust enters from the upper opening 30 of the space S, they do not adhere to the motor 11, the pinion 13, and the gear 17. For this reason, it is not necessary to perform waterproofing with respect to electrical components, such as the motor 11 and its connector, and the manufacturing cost can be reduced. In addition, since dust that has entered from the upper opening 30 does not enter between the pinion 13 and the gear 17, it is possible to prevent the problem that these wear quickly due to dust, and to extend its life. Further, since the motor 11 is located on the vehicle interior side with respect to the internal space S, the handling of a harness (not shown) connected to the motor 11 can be simplified, and the motor 11 and elements related thereto. Assembling work to the door body can be simplified.
[0034]
As previously described, in this type of conventional window regulator, the lift arm and the gear are integrated by welding or the like, so this gear cannot be arranged outside the interior space of the door body, Therefore, neither the pinion that meshes with the gear nor the motor that drives the gear could be arranged outside the internal space. However, according to the illustrated window regulator 7, the lift arm 16 and the gear 17 are separately provided. These are fixed by the pivot 14 and the pivot 14 is passed through the base plate 9 fixed to the inner panel 5 so that the gear 17 is located outside the space S, that is, on the vehicle interior side of the space S. The pinion 13 and the motor 11 can be disposed outside the space S.
[0035]
Further, as shown in FIG. 2, the window regulator 7 of the automobile of this example has a seal that seals between the outer peripheral surface of the pivot 14 and the support hole 15 of the base plate 9 into which the pivot 14 is rotatably fitted. In the example shown in the figure, an O-ring 31 is provided. The O-ring 31 is disposed between the flange 14 </ b> A of the pivot 14 and the base plate 9, and the O-ring 31 seals between the pivot 14 and the base plate 9.
[0036]
Further, when a seal member 32 made of, for example, butyl tape is interposed between the base plate 9 and the guide plate 22 and the inner panel 5, the space S between the inner panel 5 and the outer panel 4 and the interior side of the vehicle interior are further increased. It can seal more reliably. In the illustrated example, a tape-like seal member 32 is disposed along the edges of the holes 8 and 28 formed in the inner panel 5 and is sandwiched between the base plate 9 and the guide plate 22 and the inner panel 5. Yes. When the hole 28 is abolished, the seal member 32 is disposed only around the hole 8. Thus, the sealing member 32 is provided between the base plate 9 and the inner panel 5.
[0037]
With each configuration described above, rainwater and dust can be prevented from entering the vehicle interior side from the space S through the holes 8 and 28 of the inner panel 5 and the support holes 15 of the base plate 9.
[0038]
As mentioned above, although the embodiment which applied this invention to the window regulator of the side door provided in the side part of the vehicle body was described, this invention is a window regulator attached to the back door provided in the rear part of a vehicle body so that opening and closing is possible. Is also widely applicable. It is also applicable to window regulators for sashless doors without window frames.
[0039]
【The invention's effect】
According to the window regulator for an automobile according to claim 1, since the motor, the pinion and the gear are arranged not in the space between the inner panel and the outer panel but on the vehicle interior side outside this space, It is possible to prevent rainwater and dust that has entered from the upper opening from adhering. As a result, it is not necessary to use a conventional waterproofed motor, the cost can be reduced, and the life of the pinion and the gear can be extended.
[0040]
Further, according to the window regulator for an automobile described in claim 2, it is possible to prevent rainwater and dust from entering the vehicle interior from the space between the inner panel and the outer panel through the support hole.
[0041]
Furthermore, according to the window regulator for an automobile described in claim 3, it is possible to prevent rainwater and dust from entering the vehicle interior side from the space between the inner panel and the outer panel through the hole formed in the inner panel.
