Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper device for a vehicle, and more particularly, to a wiper device mounting structure for wiping a back door glass surface employing a glass hatch system.

[0002]

2. Description of the Related Art Recent wagon vehicles and hatchback vehicles use a so-called glass hatch system in which a back door glass provided in a back door for opening and closing a luggage compartment can be opened and closed separately from the opening and closing of the back door. Some have been adopted. Conventionally, such a wiper device for wiping the surface of the back door glass has been directly attached to the glass.

However, among the members constituting the wiper device, the actuator is particularly large and heavy. Therefore, a large operation force is required when opening the back door glass. When closing the glass, the glass collides with the back door. At this time, if the impact is large, a large load is applied to a portion of the glass to which the actuator is fixed, and the glass may be broken therefrom. In addition, the size of the wiper device is increased by the actuator,
The rear view is largely obstructed by the wiper device. Further, when the actuator is fixed to the glass side, a structure for supplying power to a motor as a driving source of the actuator becomes complicated.

Accordingly, there is provided a wiper device which fixes the actuator to the back door side, and rotatably supports a pivot shaft which supports the wiper arm on the glass side, and drives and connects the actuator and the pivot shaft when the glass is closed. Invented.

More specifically, the actuator swings a disk fixed to its output shaft at a predetermined swing angle. A connection hole is formed in the disk at a position radially offset from the rotation center (center axis) of the output shaft. On the other hand, the pivot shaft is rotatably supported by the pivot holder so as to be coaxial with the output shaft of the actuator,
The holder is fixed to the glass. A lever is fixed to the pivot shaft at the end on the actuator side, and the lever is provided with a connecting pin that is inserted into a connecting hole of the disk.

When the glass is closed and a connecting pin is inserted into a connecting hole of the disk, the disk and the lever are drivingly connected. That is, when the actuator operates and the disk swings at a predetermined swing angle, the lever also swings. When the pivot shaft rotates by a predetermined angle due to the swing of the lever, the wiper arm swings by a predetermined angle, and the glass surface is wiped by a wiper blade connected to the tip of the arm.

[0007]

However, when the above-mentioned wiper device is assembled to a vehicle, an axial displacement (a state in which the respective central axes are displaced) occurs between the output shaft of the actuator and the pivot shaft. In this case, the center of rotation of the disk and the center of rotation of the lever are displaced, so that the angle of rotation of the disk and the angle of rotation of the lever differ. Then, since the swing angle of the wiper arm also differs, the actual wiping locus of the wiper blade differs from the desired wiping locus. Therefore, since the mounting is performed many times while adjusting the mounting position of the pivot holder or the actuator so that the axial displacement does not occur, there is a problem that the mounting operation is complicated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to reduce the error between the actual wiping locus and a desired wiping locus without performing a complicated assembling operation. It is an object of the present invention to provide a vehicle wiper device capable of performing the above-described operation.

[0009]

In order to solve the above-mentioned problems, the invention according to the first aspect of the present invention is to provide a glass which is pivotally opened and closed with respect to a vehicle body, through a pivot shaft which supports a wiper arm, and the glass side. An actuator which is rotatably supported by a pivot holder fixed to the pivot shaft, and which rotates an output shaft arranged coaxially with the pivot shaft by a predetermined angle, is provided on the vehicle body side, and the actuator is provided on the pivot shaft when the glass is closed. A wiper device for a vehicle, wherein a first connection portion and a second connection portion provided on the output shaft are drive-connected, and a wiper arm is swung based on the operation of the actuator to wipe the glass surface. The connecting portion is provided with a connecting portion at a position radially offset with respect to a center axis of the pivot shaft, and the second connecting portion is provided with a center axis of the output shaft. The connecting portion is provided at a position radially offset with respect to the first connecting portion and at a position corresponding to the first connecting portion, and at the time of assembling to a vehicle, the pivot holder and the second portion at positions other than the connecting portion. (2) The pivot shaft and the output shaft are coaxially connected to each other so that the pivot shaft and the output shaft are coaxial. And a provisional connection member for disabling the connection state.

According to a second aspect of the present invention, in the vehicle wiper device according to the first aspect, a hole, a concave portion, into which one end of the temporary connecting member is inserted, screwed, or pressed into the pivot holder. Any one of the notches is provided, and the second connecting portion is provided with any one of a hole, a concave portion, and a notch into which the other end of the temporary connecting member is inserted, screwed, or press-fitted. The temporary connection member is formed in a shape corresponding to any one of a hole, a concave portion, and a notch provided in the pivot holder and the second connection portion.

[0011] The invention described in claim 3 is the invention according to claim 1 or 2.
In the wiper device for a vehicle described in the above, the swing trajectory of the connecting portion with the first connecting portion in the second connecting portion and the swing trajectory of the connecting portion with the temporary connecting member do not overlap with each other. The position of the connection part with the temporary connection member in the second connection part is set.

According to a fourth aspect of the present invention, a pivotable shaft that supports a wiper arm is penetrated by a glass that pivotally opens and closes with respect to a vehicle body, and is rotatably supported by a pivot holder fixed to the glass. An actuator for rotating an output shaft coaxially with the pivot shaft by a predetermined angle is provided on the vehicle body side, and a first connection portion provided on the pivot shaft when the glass is closed and a second connection provided on the output shaft. In the method for fixing a vehicle wiper device for driving and connecting a portion and wiping a glass surface by swinging a wiper arm based on the operation of the actuator, the first connection portion is positioned with respect to a center axis of the pivot shaft. The connecting portion is provided at a position offset in the radial direction by
The second connecting portion is provided with a connecting portion at a position radially offset with respect to a center axis of the output shaft and at a position corresponding to the first connecting portion, and when assembled to a vehicle, The pivot holder and the second connecting portion are temporarily connected at a position other than the connecting portion to make the pivot shaft and the output shaft coaxial, and after assembly, operation of each connecting portion and opening / closing of the glass are hindered. The pivot holder and the second connecting portion are in a non-connected state so as not to be present.

Therefore, according to the first and fourth aspects of the present invention, at the time of assembling to the vehicle, the pivot is provided at a position other than the connecting portion of the first and second connecting portions for drivingly connecting the output shaft and the pivot shaft. The holder and the second connecting portion are temporarily connected, and the pivot shaft and the output shaft are made coaxial. After the assembly, the pivot holder and the second connecting portion are brought into a non-connected state so as not to hinder the operation of each connecting portion and the opening and closing of the glass. With this configuration, when the connecting portions are connected and the pivot holder and the second connecting portion are temporarily connected at a position other than the connecting portion, the pivot shaft, the pivot holder, and the output shaft are connected at two places. Therefore, their relative positions on a plane orthogonal to the axial direction are uniquely determined, and the pivot shaft and the output shaft are surely arranged coaxially. Since the wiper device is assembled to the vehicle in this state, it is not necessary to adjust the mounting position of the pivot holder or the actuator. In addition, since the shaft deviation is prevented, the center of swing of the output shaft coincides with that of the pivot shaft, and the error between the actual wiping locus and the desired wiping locus can be suppressed.

According to the second aspect of the present invention, the pivot holder is provided with any one of a hole, a concave portion, and a notch into which one end of the temporary connecting member is inserted or screwed or press-fitted. The two connecting portions are provided with any one of a hole, a concave portion, and a notch into which the other end of the temporary connecting member is inserted, screwed, or press-fitted. The temporary connecting member is formed in a shape corresponding to any of the holes, concave portions, and cutouts provided in the pivot holder and the second connecting portion. This makes it possible to relatively easily form the temporary connecting member and a portion of the pivot holder and the second connecting portion where the temporary connecting member is connected.

According to the third aspect of the invention, the swing trajectory of the connecting portion of the second connecting portion with the first connecting portion does not overlap with the swing trajectory of the connecting portion of the second connecting portion with the temporary connecting member. ,
The position of the connection part with the temporary connection member in the second connection part is set. With this configuration, even if the second connecting portion is actuated by the actuator, the connecting portion of the connecting portion with the temporary connecting member does not interfere with the first connecting portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 to 3
1 shows a vehicle wiper device of the present embodiment. Wiper device 1
Is a wiper device for wiping the surface of a back door glass employing a glass hatch system. The wiper device 1 includes an actuator 3 mounted on the back door 2 side and a glass side unit 5 mounted on the back door glass 4 side.

The actuator 3 is formed integrally with the electric motor 6 and the speed reduction section 7 and is mounted on the mounting section 2a of the back door 2. A disk 8 is fixed to the output shaft 3a of the actuator 3 so as to be integrally rotatable, and the center of rotation (center axis L1) of the shaft 3a coincides with that of the disk 8. Then, the actuator 3 converts the rotational motion of the motor 6 into a rocking motion of the disk 8 at a predetermined rocking angle via the speed reduction unit 7.

The disk 8 has a central axis L of the output shaft 3a.
At a position from the outer circumference radially offset from 1
A connection hole 8a penetrating the front and back is formed. Connection hole 8a
Is an elliptical shape, and is formed such that its major axis is along the radial direction of the disk 8. The short diameter of the connection hole 8a is formed slightly larger than the diameter of the connection pin 14 described later. In addition, disk 8

Are arranged such that the distance from the center of rotation (center axis L1) of the disk 8 is shorter than that of the connection hole 8a. That is, the swing locus of the connection hole 8a does not overlap with that of the fitting hole 8c.

On the other hand, in the glass side unit 5, a pivot shaft 10 penetrating the front and back of the back door glass 4 is rotatably supported by a pivot holder 11 so as to be coaxial with the output shaft 3a of the actuator 3. Holder 11 is fixed to glass 4.

That is, the pivot holder 11 comprises a cylindrical portion 11a for supporting the pivot shaft 10, and a flange portion 11b provided at the longitudinal center of the cylindrical portion 11a. A screw portion 11c having a screw groove formed on the outer peripheral surface is provided on the outdoor side of the cylindrical portion 11a. An extension 20 is formed on the indoor side of the cylindrical portion 11a so as to extend radially outward. The extension 20 has a substantially circular insertion hole 20 a extending in the axial direction of the pivot shaft 10. The distance between the center of the insertion hole 20a and the center axis of the pivot shaft 10 matches the distance between the center of the fitting hole 8c and the center axis L1 of the output shaft 3a, that is, the center of both holes 8c and 20a is the center axis. It is arranged on a concentric circle centered on L1. A groove 20b extending in the axial direction is formed on the inner peripheral surface of the insertion hole 20a.

As will be described later, the insertion hole 20a and the fitting hole 8c of the disk 8 are holes into which the respective ends of the reference pin 21 used when assembling the wiper device 1 to the vehicle are fitted. . At the time of assembling, both holes 8c, 20
By attaching the reference pin 21 to the position a, the shaft displacement between the output shaft 3a and the pivot shaft 10 is prevented.

On the other hand, the glass 4 has a circular mounting hole 4a penetrating the front and back. The mounting hole 4a has an inner diameter larger than the outer diameter of the cylindrical portion 11a, and
1b is formed to be smaller than the outer diameter. A packing 22 is provided on the contact surface of the flange portion 11b with the glass 4.
Is placed. Then, the outer bush 23 is fitted into the cylindrical portion 11a in a state where the cylindrical portion 11a is inserted into the mounting hole 4a and the packing 22 of the flange portion 11b is in contact with the back surface (the indoor side surface) of the glass 4. Then, screw part 11
By tightening the nut 24 to c, the pivot holder 11 is fixed to the glass 4. The outer bush 23 and the packing 22 prevent raindrops and the like from entering the room from the mounting hole 4a.

A wiper arm 12 is fixed to an end of the pivot shaft 10 on the outdoor side, and a wiper blade (not shown) for wiping the surface of the glass 4 is connected to a tip of the arm 12. A base end of a lever 13 is fixed to the indoor side (actuator 3 side) end of the pivot shaft 10, and a connecting pin 14 inserted into a connecting hole 8 a of the disk 8 is provided at a distal end of the lever 13. Be provided. The connecting pin 14 is supported by a pin holder 13a so as to be movable in the axial direction of the pivot shaft 10, and as shown in FIG.
It is urged by a spring S provided inside the pin holder 13a so as to protrude to the side.

The pivot holder 11 has a lever 13
A restricting member 15 for restricting the swinging motion at a predetermined swinging angle is provided. An elastic member 16 is attached to a portion of the lever 13 that collides with the regulating member 15.

In the wiper device 1 configured as described above,
The glass 4 is closed and the connecting pin 1 is inserted into the connecting hole 8 a of the disk 8.
When the disk 4 is inserted, the disk 8 and the lever 13 are driven and connected. Then, when the actuator 3 is operated and the disk 8 swings from the set position at a predetermined swing angle, the lever 13 also swings by the same angle. Then, the pivot shaft 10 rotates at a predetermined angle due to the swing of the lever 13, the wiper arm 12 swings at the predetermined swing angle, and the surface of the glass 4 is wiped by the wiper blade.

As shown in FIG. 2, when the glass 4 is opened, the opening operation of the glass 4 and the connection hole 8 of the disk 8 are performed.
Since the connecting pin 14 only comes off from the position a, the glass 4 can be easily opened. And glass 4
Is closed again, the connecting pin 1 is inserted into the connecting hole 8a of the disk 8.
4, the disk 8 and the lever 13 are driven and connected again.

Here, it is assumed that when the glass 4 is opened, the lever 13 rotates from a position where the connecting pin 14 can be inserted into the connecting hole 8a for some reason. In this case, when the glass 4 is closed, the connecting pin 14 comes into contact with the surface 8b of the disk 8 and sinks. Next, when the disk 8 swings by the operation of the actuator 3, the tip of the connecting pin 14 slides on the surface 8 b of the disk 8. At this time, sliding contact resistance acts on the connecting pin 14, but the pivot shaft 10 is supported by the pivot holder 11 so that the lever 13 does not rotate with the disk 8 due to the sliding contact resistance.

When the disk 8 swings to a position where the connecting pin 14 can be inserted into the connecting hole 8a, the connecting pin 14 is inserted again into the connecting hole 8a by the urging force of the spring S. Thus, the disk 8 and the lever 13 are drivingly connected again. Thereafter, the wiper arm 12 swings based on the swing of the disk 8, and the surface of the glass 4 is wiped by the wiper blade.

Next, the wiper device 1 thus configured
Will be described with reference to FIGS. 4 to 6. First, with the glass 4 opened, the back door 2
The actuator 3 is fixed to the mounting portion 2a. next,
The connecting pin 14 is fitted into the connecting hole 8a, and the reference pin 21 is fitted over the fitting hole 8c and the insertion hole 20a, so that the pivot holder 11 is temporarily supported on the disk 8.

Here, the reference pin 21 is formed in a substantially cylindrical shape as shown in FIG. That is, the reference pin 2
1 has a fitting portion 21a formed at one end thereof to have substantially the same diameter as the fitting hole 8c of the disk 8 and fitted into the hole 8c, and has a substantially same diameter as the insertion hole 20a of the extension portion 20 at the other end. And an insertion portion 21b to be inserted into the hole 20a. The fitting portion 21a has a stepped portion 21c in contact with the surface 8b of the disk 8.
Is provided on the insertion portion 21b, and a flange portion 21d that comes into contact with the end face of the extension portion 20 on the actuator 3 side is provided. Further, at the end of the insertion portion 21b, a retaining protrusion 21e that fits into the groove 20b formed in the insertion hole 20a is formed. The length between the flange 21d side end surface of the retaining projection 21e and the retaining projection 21e end surface of the flange portion 21d is substantially the same as the axial length of the insertion hole 20a.

Then, the reference pin 21 is first
Assembled in That is, the retaining protrusion 21e is formed in the groove 20b.
Is inserted, and the insertion portion 21b is inserted until the flange portion 21d contacts the end face of the extension portion 20 on the actuator 3 side (arrow A1 in FIG. 3). Next, the reference pin 21 is rotated until the retaining projection 21e is located at a position other than the groove 20b.
At arrow A2), the reference pin 21 is prevented from coming off.

Thereafter, the connecting pin 14 is fitted into the connecting hole 8a as described above, and the fitting portion 21a is fitted into the fitting hole 8c until the step 21c abuts on the surface 8b of the disk 8. At this time, the connecting pin 14 is in contact or substantially in contact with the connecting hole 8a in the short diameter direction. Moreover, the step portion 21
c and the center axis L of the output shaft 3a by the flange portion 21d.
1 and the pivot shaft 11 are made parallel to each other, and the pivot holder 11 is supported on the disk 8 at two points, that is, the reference pin 21 and the connecting pin 14, so that the holder 11 is located on a plane perpendicular to the shafts 3a and 10. The relative position between the output shaft 3a and the output shaft 3a is uniquely determined, that is, the holder 11 is positioned in a state where the center axis L1 of the output shaft 3a coincides with that of the pivot shaft 11. That is, shaft displacement between the output shaft 3a and the pivot shaft 11 is prevented.

Next, as shown in FIG. 4, the glass 4 is closed in a state where the pivot holder 11 is temporarily supported on the disk 8, and the cylindrical portion 11 a on the outdoor side is inserted into the mounting hole 4 a of the glass 4. You. At this time, the packing 2 of the flange portion 11b is used.
2 comes into contact with the back surface of the glass 4 (the surface on the indoor side). Next, as shown in FIG. 5, the outer bush 23 is fitted into the cylindrical portion 11a. Thereafter, the nut 24 is tightened to the screw portion 11c, and the pivot holder 11 is fixed to the glass 4. Then, the wiper arm 12 is fixed at a predetermined swing end position (set position) with respect to the pivot shaft 10.

Next, as shown in FIG. 6, the glass 4 is opened. At this time, the reference pin 21 comes out of the fitting hole 8c. Then, the reference pin 21 is rotated until the retaining projection 21e reaches the position of the groove 20b, and the reference pin 21 is
Escape from 0. That is, in this embodiment, before the pivot holder 11 is fixed to the glass 4, the holder 11 is positioned with respect to the disk 8 by the reference pin 21 and the connecting pin 14 so that the shafts 3 a and 10 do not shift. The holder 11 is temporarily supported, and then the holder 11 is fixed to the glass 4. Therefore, it is not necessary to adjust the mounting position of the pivot holder 11 or the actuator 3 in order to prevent the axial displacement as in the related art, and the assembling work is simplified.
In addition, in this embodiment, since the axis deviation is prevented, the pivot center of the disk 8 coincides with the pivot center of the lever, and the error between the actual wiping locus of the wiper blade and the desired wiping locus is suppressed. .

As described above, in the present embodiment, the following functions and effects can be obtained. (1) In the present embodiment, the disk 8 and the pivot holder 11
The reference pin 21 is provided to connect over. Before fixing the pivot holder 11 to the glass 4,
Reference numeral 21 designates both shafts 3a, 1
The holder 11 was temporarily supported in a state where it was positioned with respect to the disk 8 so that the axis 0 did not shift. Thereafter, the holder 11 was fixed to the glass 4. Therefore, it is not necessary to adjust the mounting position of the pivot holder 11 or the actuator 3 in order to prevent the axial displacement as in the related art, and the assembling work can be simplified. Moreover, in this embodiment, since the axis deviation is prevented, the center of swing of the disk 8 coincides with the center of swing of the lever, and the error between the actual wiping locus of the wiper blade and the desired wiping locus is reduced. Can be.

(2) The reference pin 21 is formed in a substantially cylindrical shape, and at one end thereof is formed a fitting portion 21a which fits into a circular fitting hole 8c formed in the disk 8. At the other end, an insertion portion 21b is formed to be inserted into a substantially circular insertion hole 20a formed in the extension portion 20. Therefore, since the shapes of the reference pin 21, the fitting hole 8c, and the insertion hole 20a are relatively simple, they can be easily formed.

(3) The fitting hole 8c is arranged so that the distance from the center of rotation (center axis L1) of the disk 8 is shorter than that of the connecting hole 8a. That is, the swing trajectory of the connecting hole 8a and that of the fitting hole 8c do not overlap.
Therefore, the connecting pin 1 to be originally inserted into the connecting hole 8a
4 does not fit into the fitting hole 8c. As a result, the wiper device 1 does not malfunction.

(4) The reference pin 21 is the pivot holder 1
After fixing 1 to glass 4, it is withdrawn from wiper device 1. In this way, the reference pin 21 does not adversely affect the operation of the wiper device 1.

The embodiment of the present invention may be modified as follows. In the above embodiment, the reference pin 21 is formed as shown in FIG. 3, but the shape is not limited to this.
For example, the insertion portion 21b having the retaining protrusion 21e is
As shown in (a), a screw portion 21f having a thread groove formed on the outer peripheral surface thereof is used. On the other hand, a reference pin 25 in which the extension portion 20 is changed to a screw hole (not shown) corresponding to the screw portion 21f is used. The screw portion 20f may be screwed into the screw hole. The reference pin 25 is fixed to the wiper device 1 after the pivot holder 11 is fixed to the glass 4 in the same manner as described above.
Escaped from In this way, the reference pin 25 does not adversely affect the operation of the wiper device 1.

The insertion portion 21b and the fitting portion 21a are press-fit portions 26a and 26b, respectively, as shown in FIG. 7A, whereas the extension portion 20 and the disk 8 are also press-fit portions 26a and 26a.
Reference pin 26 changed to a hole (not shown) corresponding to 26b
May be used to press-fit the press-fit portions 26a, 26b into the respective holes. Further, both press-fitting portions 26a, 26
The intermediate portion 26c that connects b may have a small diameter, and after assembly, the intermediate portion 26c may be cut by applying an external force to the intermediate portion 26c by, for example, the operation of the disk 8 by the actuator 3. By doing so, the operation of removing the reference pin 26 from the wiper device 1 can be omitted.

Further, the reference pins 21, 25 and 26 are formed in a substantially cylindrical shape, but may be formed in other polygonal shapes such as a triangular shape and a quadrangular shape. In the above embodiment, one reference pin 21 is used to prevent the axis deviation between the output shaft 3a and the pivot shaft 10, but the axis deviation is reduced by using two or more reference pins. It may be prevented.

In the above embodiment, the position of the fitting hole 8c is set so that the swing locus of the connecting hole 8a does not overlap with that of the fitting hole 8c, but the position of the hole 8c is limited to this. It is not something to be done. In this case, it is desirable to set the position of the fitting hole 8c so that the swing locus of the connecting hole 8a does not overlap with that of the fitting hole 8c. By doing so, the connecting pin 14 that should be originally inserted into the connecting hole 8a does not fit into the fitting hole 8c, and thus malfunction of the wiper device 1 can be prevented.

In the above-described embodiment, the wiper device 1 is provided between the back door 2 and the glass 4 rotatably supported on the door 2. The wiper device as described above may be provided between the glass and the glass supported to be rotatable and openable with respect to the vehicle body.
