DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper device for wiping windshield glass or the like of an automobile.

[0002]

2. Description of the Related Art A wiper device for wiping a windshield glass of an automobile includes a wiper arm attached to a pivot shaft which reciprocates within a predetermined range by rotation of the pivot shaft, thereby wiping raindrops or the like on a windshield glass surface. I do.

[0003] In such a wiper device, the pivot shaft is rotatably supported by a wiper bracket having a pivot holder. The wiper bracket is fixed to a vehicle body (for example, a cowl panel disposed below the windshield glass) by mounting bolts. In a vehicle having a pair of wiper arms and blades, pivot shafts are provided on both sides in the vehicle width direction, and wiper brackets for supporting the pivot shafts are also fixed on both sides in the vehicle width direction of the vehicle body. Furthermore, there is a so-called frame-integrated wiper device in which these pair of wiper brackets are integrated with a frame as a support base for a wiper motor or the like (for example, Japanese Patent Application Laid-Open No. 9-175336).

In the wiper device disclosed in the above publication, a bracket is welded and fixed to a support pipe (pipe frame) that connects a pair of pivot holders to each other, and a wiper motor is attached and fixed to the bracket. Of the assembly. According to such a structure, the system can be configured to be easy to handle, easy to mount, and highly rigid. Further, such a frame-integrated wiper device usually has mounting holes at at least three points (places) in total of a pair of pivot holders and the motor mounting bracket, and fasteners such as bolts inserted into each mounting hole. Is firmly fixed to the vehicle body.

In a configuration in which a pair of pivot holders and a bracket are fixed to the vehicle body at a total of three points (locations) as in the wiper device, the fixing position is necessarily (uniquely) determined at the three points. However, if the mounting position of the frame assembly (each pivot holder) on the vehicle body side shifts, it must be adjusted. In this case, usually, the adjustment is performed by forming any one of the three mounting holes (for example, two mounting holes) into a long hole or a large so-called stupid hole, thereby finely adjusting the mounting position. are doing. However, in such an adjustment, the work for accurately fixing the wiper device to the vehicle body is complicated, and the mounting workability is poor.

Accordingly, the present applicant has already developed a wiper device which not only can be mounted at a predetermined position with high accuracy, but also allows fine adjustment of the mounting position, facilitates the mounting work, and reduces the number of working steps and the number of parts. (Japanese Patent Application No. 10-241500).

As shown in FIG. 10, in the proposed wiper device 170, a pair of left and right pivot holders 172 are connected to each other by a frame 174.
A motor 176 as a drive source is directly fixed to 74,
The whole is configured as a motor & link assembly. Further, the wiper device 170 is fixed in a predetermined state with respect to the vehicle body at three support positions X, Y, and Z. That is, the support pin 180 is inserted into the support hole 178 provided in the vehicle body at the reference position Z among the support positions X, Y, and Z. In this state, the support pins 180 other than the support pin 180 are fixed by fixing means (bolts or the like). The support positions X and Y are fixed to the vehicle body. As described above, when the wiper device 170 is supported and fixed to the vehicle body in a predetermined state after a certain reference position is determined, the reference position Z (the support hole 178 and the support pin 18) is set.
0), the positioning is performed, and the vehicle is fixed to the vehicle body in a state where it is positioned at the reference position Z (a predetermined state based on the reference position Z).

Here, suppose that the wiper device 1 for the vehicle body is used.
If a shift occurs in the fixed position of 70, it must be adjusted. In this case, as described above, the reference position Z (support hole 1
78 and the support pin 180), when the support positions X and Y other than the support pin 180 are fixed to the vehicle body by the fixing means after the positioning is performed, the support pin 180 inserted through the support hole 178 is moved in its axial direction. Because it is movable,
Fine adjustment of the fixed position can be easily performed without changing the reference support position Z. In addition, at the reference position Z (the support hole 178 and the support pin 180), another fixing component (for example, a bolt or the like) is not required, and the support is performed by simply inserting the support pin 180 into the support hole 178. Therefore, the fixing workability is excellent and the number of parts for fixing is reduced. Furthermore, if the flange portion 182 provided on the support pin 180 is used as a reference plane for determining the amount of insertion of the support pin 180, the flange portion 182 can be used to support a wiper device having a different amount of insertion of the support pin 180 into the support hole 178. The support at the reference position Z can be performed without variation only by changing the formation position of the portion 182.

As described above, the proposed wiper device 17 is provided.
A value of 0 allows not only accurate mounting at a predetermined position, but also easy fine adjustment of the mounting position, good mounting workability, and reduction in the number of work steps and the number of parts.

However, the proposed wiper device 170 requires a special space for assembling. Hereinafter, this point will be described in detail.

As described above, the proposed wiper device 17
The 0 support pin 180 is a reference position for the motor and link assembly with respect to the vehicle body, and of course also supports the vehicle body. The following are considered in this support.

That is, assuming that the motor and link assembly is mounted on the vehicle body only at two points (support positions X and Y) where the two pivot holders 172 are mounted on the vehicle body, as shown schematically in FIG. Rotation direction B with virtual axis L connecting two points (support positions X, Y) as rotation axis A
Weak support for the load. Therefore, the support pin 180 projecting from the motor 176 is inserted into the support hole 178 of the vehicle body to support the load in the rotation direction B.

At this time, the projecting direction of the support pin 180 is
In the tangential direction C of the rotation axis A at the formation position, it is also the direction in which the support pin 180 comes out of the support hole 178, and the support is still weak in the rotation direction B.

Therefore, the support pin 180 is made to project in the direction D perpendicular to the tangential direction C of the rotation axis A at the position where the support pin 180 is formed, thereby supporting the load in the rotation direction B. For the above reasons, the support pins 180 need to be formed so as to protrude in a direction D perpendicular to the tangential direction of the rotation axis A at the position where the support pins 180 are formed. However, due to this, motor &
When assembling the link assembly to the vehicle body,
As shown in the figure, since the upper part is generally open due to the vehicle body structure, the motor & link assembly is mounted on the cowl box 18.
After being accommodated from the upper side to the lower side in the inside 4, the vehicle must be slid in the vehicle front-rear direction (the direction in which the support pins 180 are inserted).

That is, when the wiper device 170 constituted as a motor and link assembly is mounted on the vehicle body, as shown by an arrow E in FIG. It is necessary to slide in the direction (the direction in which the support hole 178 provided in the vehicle body panel 186 is present), and furthermore, it is necessary to secure a space for the sliding movement over the entire area in the vehicle width direction. Moreover, this space is necessary only for attaching the motor and link assembly to the vehicle body, and becomes a useless space after assembly.

As described above, the proposed wiper device 17 is used.
In the case of 0, a special space for assembling was required, and there was room for improvement in this respect.

At the corners of the pivot holders 12, 14, mounting holes 28, 30 are formed, respectively.
The wiper device 10 is configured to be fixed to the vehicle body by fixing bolts (not shown) inserted into the mounting holes 28 and 30. Here, the driver side pivot holder 1
The mounting hole 28 provided in the second 2 is a long hole, and can slide in one direction with respect to the fixing bolt in a non-fastened state. On the other hand, the mounting hole 30 provided in the pivot holder 14 on the passenger seat side is formed to have a larger diameter than the fixing bolt (a so-called stupid hole), and in a non-fastened state, in all directions with respect to the fixing bolt. It is possible to slide.

The pivot shafts 12 and 14 have connecting shafts 3 on the side wall portions opposite to the mounting holes 28 and 30.
2, 34 are provided. Further, the connection shaft 32 and the connection shaft 34 are connected to each other by a frame 42.

A mounting portion 48 is formed at a longitudinally intermediate portion of the frame 42. The mounting portion 48 is formed in a U-shaped cross section that is not hollow, and the upper surface thereof is a mounting flat seat surface 50. A mounting portion 48 of the frame 42 has a wiper motor 58 as a drive source
Is attached. The wiper motor 58 has a configuration in which a motor section 58A and a gear section 58B are provided integrally, and a pair of mounting feet 62 are formed to project from a housing 60 of the gear section 58B. The mounting foot 62 is placed on the mounting flat seat surface 50 of the mounting portion 48 of the frame 42,
In this state, it is configured to be fastened and fixed by bolts 64.

As described above, the wiper device 10 has a so-called frame integrated structure in which the pair of pivot holders 12 and 14 are integrally formed with the frame 42 as a support base for the wiper motor 58.

In the wiper device 10, a support pin 68 is formed so as to protrude from the housing 60 of the wiper motor 58. The support pin 68 is formed so as to protrude toward the front side of the housing 60 (in a direction substantially perpendicular to the longitudinal direction of the frame 42), and is provided at a plurality of support positions when the wiper device 10 is mounted and fixed to the vehicle body. One of them is a reference position for positioning, and is inserted into a support hole 86 on the vehicle body side described in detail later. The support pins 6
The rear end portion 8 is formed with a flange portion 84, which also contacts a support hole 86 on the vehicle body, which will be described in detail later.

The output shaft of the wiper motor 58 protrudes toward the back side of the housing 60, and has a tip connected to a link rod 76 and a link rod 78 via a crank arm. One link rod 76 is connected to the pivot lever 24 of the pivot shaft 20 supported by the pivot holder 12, and the other link rod 78 is connected to the pivot lever 26 of the pivot shaft 22 supported by the pivot holder 14. It is connected to. As a result, the operation of the wiper motor 58 causes the link rods 76 and 78 and the pivot lever 2 to move.
Driving force is transmitted through the pivot shafts 4 and 26, and the pivot shafts 20 and 22 respectively rotate.

As shown in FIGS. 2 and 3, a bracket 80 as a support member is provided on the panel 85 on the vehicle body side.
The bracket 80 has a support hole 86 corresponding to the support pin 68 formed in the housing 60 of the wiper motor 58 described above.
Are formed. The support hole 86 is provided in the wiper device 10.
Has a long shape in the longitudinal direction of the frame 42,
Moreover, an opening 80A is formed by opening one end of the frame 42 along the longitudinal direction. A peripheral wall 82 extending in the axial direction of the support pin 68 is formed on the peripheral edge of the support hole 86. The support holes 86 correspond to one of a plurality of support positions when the wiper device 10 is mounted and fixed to the vehicle body, and serve as a reference position for positioning.

In the opening 80A of the bracket 80,
When the support pin 68 or the grommet 87 is inserted into the support hole 86, the taper surface 86A is formed wide in the opening direction so as to be easily inserted and guided.

A grommet 87 made of an elastic material is attached to the support hole 86. This grommet 8
Reference numeral 7 denotes a cylindrical portion 88 whose outer periphery is fitted into and supported by the support hole 86, and a receiving portion 89 formed at one end of the cylindrical portion 88.
The support pin 68 is inserted into the insertion hole 87A, and the flange portion 84 comes into contact with the receiving portion 89 when the support pin 68 is inserted into the insertion hole 87A. That is,
The support pin 68 is inserted until the flange portion 84 comes into contact with the receiving portion 89 of the grommet 87, and in this state, the support pin 68 (including the grommet 87) is slid from one end opening side (opening 80A) of the support hole 86. Can be inserted. That is, the insertion of the support pin 68 into the support hole 86 can be performed by sliding the wiper device 10 configured as a motor and link assembly only along the longitudinal direction of the frame 42. Thus, the support pin 68 is moved through the grommet 87 to the support hole 86.
10 and 11, the clearance between the support hole 86 and the grommet 87 is such that there is no backlash in the direction of arrow C about the virtual straight line L in FIGS. And between the insertion hole 87A of the grommet 87 and the support pin 68. As a result, the positioning and support of the wiper device 10 configured as a motor & link assembly is achieved, and in this state, the fixing bolts inserted into the mounting holes 28 and 30 of the pivot holders 12 and 14 are fastened.
The wiper device 10 is configured to be fixed to a vehicle body.

The ends of the pivot shafts 20 and 22 of the wiper device 10 having the above configuration are respectively attached to the wiper arms &
A blade (not shown) is attached, and the wiper arm & blade reciprocates within a predetermined range by rotation of each of the pivot shafts 20 and 22.

Next, the operation of the first embodiment will be described.

In the wiper device 10 having the above configuration, the pivot holders 12 and 14 that rotatably support the pivot shafts 20 and 22 are connected to each other by the frame 42.
Further, a wiper motor 58 is directly fixed to the attachment portion 48 (the attachment flat seat surface 50) of the frame 42, and is in an assembled state as a whole. In this state, the wiper motor 5
8 is provided with a support pin 68 provided in a panel 85 on the vehicle body side (a grommet 8).
7), is positioned and supported, and is fixed to the vehicle body structural member below the windshield glass by fixing bolts inserted through the mounting holes 28, 30 of the pivot holders 12, 14.

Further, the operation of the wiper motor 58 causes the pivot shafts 20 and 22 to rotate, and the wiper arm and blade reciprocate within a predetermined range to wipe out raindrops and the like on the windshield glass.

Here, in the wiper device 10, a support hole 86, which is a reference position among a plurality of support positions, is provided in the panel 85 on the vehicle body side, and a grommet 87 attached to the support hole 86 is received. The support pin 68 is inserted and positioned and supported until the flange portion 84 abuts on the portion 89. In this state, the fixing bolts inserted into the mounting holes 28 and 30 of the pivot holders 12 and 14 are fastened. Thus, the wiper device 10 is fixed to the vehicle body.

As described above, when the wiper device 10 is supported and fixed to the vehicle body in a predetermined state after a certain reference position is determined, positioning is performed at the reference position (the support hole 86 and the support pin 68). It is fixed to the vehicle body in a positioned state (a predetermined state based on the reference position).

Here, temporarily, the wiper device 1 for the vehicle body
If a deviation occurs at the fixed position of 0, it must be adjusted. In this case, when the portions other than the support pins 68 (the mounting holes 28 and 30 of the pivot holders 12 and 14) are fixed to the vehicle body after the positioning is performed at the reference positions (the support holes 86 and the support pins 68) as described above. Since the support pins 68 inserted into the support holes 86 (grommets 87) are movable in the axial direction, fine adjustment of the fixed position can be easily performed without changing the reference support position. Moreover, at the reference support position (the support hole 86 and the support pin 68), another fixing component (for example, a bolt or the like) is not required, and the simple support pin 68 is inserted into the support hole 86 (the grommet 87). Because it is a supported configuration,
Excellent fixing workability reduces the number of parts for fixing.

Further, in this case, the pivot holders 12, 1
Of the four mounting holes 28, 30, the mounting hole 28 provided in the driver side pivot holder 12 is a long hole, and can slide in one direction with respect to the fixing bolt in a non-fastened state. The mounting hole 30 provided in the pivot holder 14 on the passenger seat side is formed to have a larger diameter than the fixing bolt (a so-called stupid hole), and can slide in all directions with respect to the fixing bolt in a non-fastened state. Has become.
Accordingly, the setting of the wiping range of the wiper arm and blade on the driver's seat side (determining the set position to prevent overrun and interference) can be prioritized so as not to hinder the driving operation of the driver. That is, since the mounting hole 28 on the driver's seat side is an elongated hole and can slide in only one direction with respect to the fixing bolt, the adjustment range of the fixing position is narrow, and the fixing position is fixed very close to the reference setting position. On the other hand, since the mounting hole 30 on the passenger seat side is formed to have a larger diameter than the fixing bolt and can slide in all directions, the adjustment range of the fixing position is wide, and the adjustment can be completed in the mounting hole 28 on the driver seat side. It can be adjusted to allow for the missing part.

In this wiper device 10, the support pin 68 is inserted through the insertion hole 87 A of the grommet 87, and the flange 84 abuts on the receiving portion 89 of the grommet 87 and is supported and fixed. Vibrations that occur at times are absorbed by the grommet 87, and the vibration from the wiper motor 58 is prevented from being transmitted from the support pins 68 to the vehicle body via the support holes 86 (panel 85).
In addition, it is possible to prevent the flange portion 84 from directly abutting on the panel 85 (the peripheral wall of the support hole 86) to generate abnormal noise.

If the flange 84 is used as a reference surface for determining the amount of insertion of the support pin 68, the support hole 86 of the support pin 68
(Grommet 87) Wiper device 10 with different insertion amount
Can be supported at the reference position without variation only by changing the formation position of the flange portion 84.

Furthermore, the wiper device 10 does not require a special space for assembling.

That is, the support hole 86 of the bracket 80 for supporting the wiper device 10 on the vehicle body is
Is open at one end along the longitudinal direction of the support hole 86 to form an opening 80A.
The support pin 68 (including the grommet 87) can be inserted by sliding. That is, when the support pin 68 is inserted into the support hole 86, the wiper device 10 configured as a motor & link assembly is
This can be done by sliding along the longitudinal direction. This eliminates the need to secure a slide area over the entire length of the frame 42 in the longitudinal direction of the frame 42 for the insertion operation, unlike the conventional case where the frame 42 is inserted from a direction perpendicular to the longitudinal direction of the frame 42. The link assembly can be easily mounted on the vehicle body in a small space.

Further, in this case, the support hole 86 is
2 has a long shape in the longitudinal direction (sliding direction when the motor and link assembly is mounted), so that the slide insertion at the time of mounting can be guided and mounting workability is improved. Further, since the peripheral wall 82 extends in the support hole 86 in the axial direction of the support pin 68, the contact area between the support pin 68 (the grommet 87) and the support hole 86 increases. Therefore, the support pin 68 can be received on a surface as large as possible, the surface pressure when the drive reaction force of the wiper motor 58 acts on the support pin 68 is reduced, and the strength of the support pin 68 and the like can be easily secured. . Further, since the tapered surface 86A is formed wide in the opening direction at the opening 80A of the bracket 80, the insertion can be easily guided when the support pin 68 or the grommet 87 is inserted into the support hole 86.

As described above, the wiper device 10 according to the first embodiment can be mounted at a predetermined position with high accuracy, the fine adjustment of the mounting position is easy, and the mounting workability is good.
Not only the number of work steps and the number of parts can be reduced, but also no special space for assembling is required.

The opening direction of the support hole 86 formed in the bracket 80 (the opening direction of the opening 80A) is limited to the mounting direction of the wiper device 10 (motor & link assembly) on the vehicle body and the longitudinal direction of the frame 42. Not something. For example, as in the bracket 81 shown in FIG. 4, the opening direction of the support hole 86 (the opening direction of the opening 81A) may be formed in the vertical direction (the mounting direction of the wiper device). In this case, since the opening 81A is provided along the mounting direction (arrow A) on the cowl box, it is inserted from the opening 81A simultaneously with mounting of the wiper device, and then slid in the frame longitudinal direction (arrow B). It can be supported in this way.

Next, another embodiment of the present invention will be described. Note that components that are basically the same as those in the first embodiment are given the same reference numerals as in the first embodiment, and descriptions thereof are omitted.
