[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle wiper device for wiping a surface to be wiped.
[0002]
[Prior art]
In a vehicle wiper device that wipes a surface to be wiped (glass surface, etc.) of a vehicle, in order to prevent deformation of the blade rubber due to the blade rubber of the wiper blade being pressed against the surface to be wiped for a long time by the arm pressure of the wiper arm. In some cases, a lift-up mechanism for lifting the wiper blade is provided (for example, Japanese Patent Laid-Open No. 2000-289577).
[0003]
Here, in the vehicle wiper device provided with the lift-up mechanism, the wiper blade is rotatably supported by the wiper arm by the support shaft, and the slider is attached to the wiper arm. A lifter is provided at the stop position of the wiper blade, and when the wiper blade is moved to the stop position, the wiper blade is lifted up by preventing the blade rubber from being deformed by riding the slider on the lifter.
[0004]
By the way, in the vehicle wiper device provided with such a lift-up mechanism, a large number of parts such as screws and rivets for attaching the slider to the wiper blade as described above are necessary, and the number of parts as a whole is large. there were.
[0005]
Furthermore, while the vehicle is traveling (especially when traveling on a rough road), the lifted wiper blade is rotated around the support shaft by the vibration of the vehicle, and both ends of the wiper blade come into contact with the vehicle and a flickering noise is generated. There was a case.
[0006]
For this reason, conventionally, for example, an E-type clip is provided at the tip of the wiper arm, the wiper blade is sandwiched by the E-type clip, and a Z-shaped leaf spring stopper is inserted between the E-type clip and the wiper blade. . Then, the flapping noise is suppressed by preventing the wiper blade from rotating by the urging force of the leaf spring stopper. Alternatively, when the wiper blade is lifted up by the slider, the wiper blade is positively held in contact with the wiper arm, thereby preventing unnecessary rotation of the wiper blade and suppressing flickering noise. Some of them have the same structure.
[0007]
However, in the conventional vehicle wiper device as described above, the support part of the wiper blade has a special structure (E-type clip, leaf spring stopper, etc.), and further, the number of parts and the number of assembly processes of this support part increase. Cost increases. Alternatively, in order to separately attach the slider to the wiper blade, considering the assembly work, most of the slider is exposed to the outside so that the appearance is impaired and a separate part for installation is required. The number of points and work man-hours increased.
[0008]
[Problems to be solved by the invention]
In consideration of the above-described facts, the present invention provides a vehicle wiper device that not only suppresses fluttering noise caused by lifted-up wiper blades, but also improves the appearance and reduces the number of parts and assembly steps. Is the purpose.
[0009]
[Means for Solving the Problems]
According to a first aspect of the present invention, a vehicle wiper device is formed in a U-shaped cross section having a pair of side walls and an upper wall and opened in the direction of the surface to be wiped of the vehicle. A wiper arm that moves, and is rotatably supported by a support shaft at the tip of the wiper arm, contacts the wiped surface by arm pressure applied from the wiper arm, and reciprocates together with the wiper arm to wipe the wiped surface A wiper blade, and a base portion and a slide portion, wherein the base portion is offset from the support shaft toward the wiper arm side and provided on the longitudinal base end side of the wiper blade, and the slide portion is at the wiper blade stop position And a slider provided so as to protrude in the direction, and provided in the vehicle corresponding to a stop position of the wiper blade, and when the wiper blade stops, A wiper device for a vehicle comprising a lifter that abuts on a ride part and raises the wiper blade in a direction away from the surface to be wiped, wherein the base part of the slider and the wiper blade provided with the base part are provided. At the base end in the longitudinal direction, the wiper blade is Rotates to approach the wiper arm The wiper arm is housed in a lumen portion surrounded by the pair of side walls and the upper wall. Configured to The side wall on the wiper blade stop position side of the pair of side walls of the wiper arm, It is a part of the longitudinal direction and is cut out so as not to interfere with the slide part of the slider when the wiper blade is rotated so as to approach the wiper arm. It is characterized in that a notch is formed.
[0010]
In the vehicle wiper device according to the first aspect, the wiper blade that is rotatably supported by the wiper arm by the support shaft is pressed toward the wiping surface of the vehicle by the arm pressure. A slider is provided on the wiper blade so as to be displaced from the support shaft toward the wiper arm.
[0011]
When the wiper blade is stopped, the slide portion of the slider provided on the wiper blade comes into contact with the lifter, so that the wiper blade is lifted up in a direction away from the surface to be wiped. Here, since the slider is displaced from the support shaft to the wiper arm side and is provided on the wiper blade, when the wiper blade is lifted up, the wiper blade is moved from the lifter to the wiper blade (hereinafter referred to as “anti-lifter”). Rotation force around the support shaft is generated in the “direction”. That is, when the wiper blade is lifted up, the slider and the wiper blade longitudinal base end side on the slider mounting side rotate so as to approach the wiper arm.
[0012]
For this reason, the wiper blade or slider and the wiper arm engage with each other at a position different from the support shaft. At this time, since the arm pressure is applied to the wiper arm, the wiper blade is pressed against the lifter through the engagement point with the wiper arm or the slider. Therefore, the wiper blade is supported in a state where the rotation about the support shaft is limited by the above-described engagement, and even if the blade rubber of the wiper blade is completely separated from the surface to be wiped, the wiper blade is wiped by vibration of the vehicle or the like. The blade does not flutter, and fluttering noise can be suppressed.
[0013]
Further, in this vehicle wiper device, the base portion of the slider and the longitudinal base end portion of the wiper blade provided with the base portion are provided so as to be accommodated in the inner cavity portion of the wiper arm formed in a U-shaped cross section. Therefore, when the wiper blade is lifted up (that is, when the slider and the wiper blade longitudinal base end on the slider mounting side are rotated so as to approach the wiper arm), the base of the slider And the longitudinal direction base end side of the wiper blade is in a state of being accommodated in the inner cavity portion of the wiper arm formed in a U-shaped cross section by the rotation of the wiper blade around the support shaft. Therefore, the base of the slider is not exposed to the outside, and the wiper blade longitudinal direction base end on the slider mounting side can be minimized to the outside. It becomes a state and the appearance improves.
[0014]
Thus, in the vehicle wiper device according to the first aspect, not only can the flicker noise caused by the lifted-up wiper blade be suppressed, but also the appearance can be improved. In the vehicle wiper device according to the first aspect, of the pair of side walls of the wiper arm, the side wall on the wiper blade stop position side is a part of the longitudinal direction and is rotated so that the wiper blade approaches the wiper arm. Since a notched portion is formed so as not to interfere with the slide portion of the slider when moved, When the wiper blade is lifted up, each portion (base) other than the slider slide portion is accommodated in a state where it is completely hidden in the lumen portion of the wiper arm by rotating the wiper blade around the support shaft. Can be improved. Further, even during a normal wiper device wiping operation, the slide portion of the slider does not inadvertently interfere with the side wall of the wiper arm, and the wiper rotates around the support shaft following the shape of the wiped surface of the vehicle. The blade operation is not hindered.
[0015]
A vehicle wiper device according to a second aspect of the present invention is the vehicle wiper device according to the first aspect, wherein the wiper blade has a plurality of holding levers, and at least the slider is provided among the holding levers. The lever and the slider are made of resin and are integrally formed.
[0016]
In the vehicle wiper device according to claim 2, since the slider is integrally formed with the first lever, a special screw or rivet for attaching the slider becomes unnecessary, and the number of parts and the number of assembling steps are reduced. In addition, the parts management of the slider becomes unnecessary. In addition, since the slider is not assembled to the wiper blade later, even if the slider is arranged in the inner cavity portion of the wiper arm, the assembling workability is not impaired and the appearance can be improved.
[0019]
Claim 3 The vehicle wiper device according to the present invention includes: Claim 1 or claim 2 In the vehicle wiper device, the wiper blade provided with the slider in contact with the back surface of the upper wall of the wiper arm is attached to the base of the slider. Said A posture holding unit that holds the wiper arm in a predetermined posture is provided.
[0020]
Claim 3 In the vehicle wiper device described above, when the wiper blade is lifted up by the sliding portion of the slider coming into contact with the lifter, that is, the wiper blade generates a rotational force around the support shaft, and the slider and the slider mounting side. When the base end of the wiper blade in the longitudinal direction is rotated so as to approach the wiper arm, the posture holding portion of the slider comes into contact with the rear surface of the upper wall of the wiper arm and lifts the wiper arm as it is. At this time, since the arm pressure is applied to the wiper arm, the wiper blade is pressed against the lifter by the contact. Therefore, the wiper blade is supported in a state where the rotation around the support shaft is limited by the contact. As described above, since the posture holding unit is lifted up in contact with the upper wall rear surface of the wiper arm, the distance between the wiper arm and the wiper blade does not fluctuate at the time of lift up (the wiper arm and the wiper blade are constant). This makes it possible to show the attitude of the wiper arm and wiper blade and the operation thereof at the time of lift-up more smartly.
[0021]
Claim 4 The vehicle wiper device according to the present invention is as follows. 3 The vehicle wiper device according to claim 1, wherein the wiper arm and Said In a plan view of the wiper blade, the longitudinal axis of the wiper arm and the longitudinal axis of the wiper blade coincide with each other, and the posture holding portion is disposed on both the longitudinal axes.
[0022]
Claim 4 In the described vehicle wiper device, the rotation surface of the wiper blade with respect to the wiper arm (that is, the surface that includes the longitudinal axis of the wiper arm and the longitudinal axis of the wiper blade and is orthogonal to the support shaft), and lift-up of the wiper arm and wiper blade The direction (direction in contact with and away from the surface to be wiped) of the vehicle and the operating position (action point) of the turning force acting on the wiper arm to lift up coincide with each other on the same plane. It is possible to prevent “twisting force” from acting on each connecting portion such as the wiper arm and the wiper blade.
[0023]
DETAILED DESCRIPTION OF THE INVENTION

The vehicle wiper device 10 includes a wiper arm 12 and a wiper blade 14.
[0025]
The wiper arm 12 has a retainer 16 rotatably supported by a hinge at the tip of an arm head (not shown) provided in the vehicle. The retainer 16 is made of resin and has a pair of side walls 18A, 18B and an upper wall 20, and is formed in a U-shaped cross section having an opening in the direction of the surface to be wiped. The tip of the retainer 16 is a hook portion 22. In addition, a notch 24 is formed in the vicinity of the hook portion 22 on a side wall 18A on the wiper blade 14 stop position side, which will be described later, of the pair of side walls 18A and 18B of the retainer 16. The notch 24 is formed corresponding to a slide part 38 of the slider 34 and a buffer part 42 of the holding block 40 which will be described later.
[0026]
A tension coil spring (not shown) is attached to the interior of the retainer 16 between the arm head and an arm pressure is applied to the wiper arm 12 (retainer 16) by the biasing force of the tension coil spring.
[0027]
On the other hand, the wiper blade 14 includes a primary lever 26, a secondary lever 28, and a blade rubber 30 as a first lever. The primary lever 26 is made of resin like the wiper arm 12, and a support shaft 32 is provided in the vicinity of the base end portion in the longitudinal direction. The hook portion 22 of the wiper arm 12 (retainer 16) is locked to the support shaft 32, so that the wiper blade 14 is mounted on the wiper arm 12 so as to be rotatable within a predetermined range.
[0028]
Further, in this case, the wiper arm 12 and the wiper blade 14 configured as described above are connected in a state in which the longitudinal axis φ of the wiper arm 12 and the longitudinal axis φ of the wiper blade 14 coincide with each other in plan view (as shown in FIG. 3). It has been configured.
[0029]
The primary lever 26 of the wiper blade 14 is provided with a slider 34. The slider 34 is made of resin and includes a base portion 36 and a slide portion 38. The base portion 36 is displaced from the support shaft 32 toward the wiper arm 12, and is integrated with the primary lever 26 on the base end side in the longitudinal direction of the primary lever 26. Is formed. Further, the slide portion 38 of the slider 34 is provided so as to protrude toward the wiper blade 14 stop position (perpendicular to the wiper blade 14).
[0030]
Further, a holding block 40 is attached to the slider 34. The holding block 40 includes a buffer portion 42 covered with a rubber cover 41 and a posture holding portion 44, and is integrally attached to the base portion 36 of the slider 34. The buffer portion 42 is provided on the side of the slide portion 38 of the slider 34 so as to protrude in the same manner as the slide portion 38. The buffer portion 42 functions as a stop position and a buffer material when the wiper blade 14 is lifted up. Have. On the other hand, the posture holding portion 44 is formed so as to protrude toward the upper wall 20 of the wiper arm 12 (retainer 16), and can contact the rear surface of the upper wall 20 of the retainer 16. That is, when the wiper blade 14 is lifted up, the posture holding portion 44 comes into contact with the rear surface of the upper wall 20 of the retainer 16, thereby moving the wiper arm 12 together with the wiper blade 14 and moving the wiper blade 14 to the wiper arm 12. Is held in a predetermined posture.
[0031]
Here, as described above, the wiper arm 12 and the wiper blade 14 are connected so that their longitudinal axes φ coincide with each other in plan view (shown in FIG. 3). The part 44 is configured to be disposed on both the longitudinal axes φ.
[0032]
Further, here, the base portion 36 of the slider 34, the longitudinal base end portion of the primary lever 26 of the wiper blade 14 provided with the base portion 36, and the posture holding portion 44 of the holding block 40 are connected to the pair of side walls 18A and 18B. It is provided so as to be accommodated in the lumen portion X of the wiper arm 12 having a U-shaped cross section formed by the wall 20. In this case, the notch 24 is formed in the side wall 18A of the retainer 16 on the wiper blade 14 stop position side by being cut out in a shape corresponding to the slide part 38 of the slider 34 and the buffer part 42 of the holding block 40. Even if the slide portion 38 of the slider 34 protrudes toward the wiper blade 14 stop position (perpendicular to the wiper blade 14), the slide portion 38 is configured not to interfere with the side wall 18A. .
[0033]
The wiper arm 12 and the wiper blade 14 having the above configuration are fixed to a pivot shaft (not shown) via an arm head, and the wiper blade 14 reciprocates together with the wiper arm 12 by driving the wiper motor to wipe the windshield glass 16. It is the composition to do.
[0034]
Further, as schematically shown in FIG. 3, a lifter 46 is provided on the cowl cover of the vehicle. The lifter 46 is provided corresponding to the slider 34 of the wiper blade 14 at the stop position of the vehicle wiper device 10, and when the vehicle wiper device 10 (the wiper arm 12 and the wiper blade 14) reaches the stop position. A slide portion 38 of the slider 34 rides on the lifter 46. Thereby, the wiper blade 14 is lifted up when the vehicle wiper device 10 is stopped.
[0035]
The height of the lifter 46 is set such that when the wiper blade 14 is lifted up, the entire blade rubber 30 of the wiper blade 14 is completely separated from the vehicle (windshield glass) and does not come into contact therewith. Yes.
[0036]
Next, the operation of the present embodiment will be described.
[0037]
When the vehicle wiper device 10 is operated, the wiper blade 14 reciprocates together with the wiper arm 12 by driving a wiper motor (not shown) to wipe the windshield glass.
[0038]
When the vehicle wiper device 10 is stopped, the wiper arm 12 and the wiper blade 14 reach the stop position, and the slide portion 38 of the slider 34 attached to the wiper blade 14 rides on the lifter 46. As a result, the wiper blade 14 is lifted up. Therefore, when the wiper blade 14 is lifted up, the entire blade rubber 30 of the wiper blade 14 is not completely separated from the vehicle (windshield glass) and does not come into contact therewith, so that arm pressure is applied to the blade rubber 30 for a long time. Therefore, the deformation of the blade rubber 30 can be prevented.
[0039]
Here, when the wiper blade 14 is lifted up, as shown in FIG. 2, the wiper blade 14 is pressed in the vehicle direction (direction of arrow A in FIG. 2) on the support shaft 32 by the arm pressure of the wiper arm 12. At the same time, the wiper blade 14 is pushed up by the lifter 46 in the anti-lifter direction (the direction from the lifter 46 to the wiper blade 14, the direction of arrow B in FIG. 2). In this case, since the slider 34 attached to the wiper blade 14 is offset from the support shaft 32 toward the wiper arm 12, the support shaft 32 is provided on the wiper blade 14 in the direction indicated by arrow C in FIG. 2. Around the power is generated.
[0040]
For this reason, the wiper blade 14 rotates in the direction of arrow C in FIG. 2, and the posture holding portion 44 of the holding block 40 abuts against the back surface of the upper wall 20 of the retainer 16 to lift the wiper arm 12 as it is (the wiper arm 12 is lifted). The wiper blade 14 is held together with the wiper arm 12 in a predetermined posture (while the rotational force in the direction indicated by arrow C in FIG. 2 is applied). Therefore, the wiper blade 14 does not flutter due to the vibration of the vehicle or the like, and the flutter noise can be suppressed.
[0041]
Here, in this vehicle wiper device 10, the base portion 36 of the slider 34 and the longitudinal base end portion of the wiper blade 14 (primary lever 26) provided with the base portion 36 are formed in a U-shaped cross section. 12 (retainer 16) so that the wiper blade 14 is lifted up (that is, the slider 34 and the wiper blade 14 on the side where the slider 34 is mounted (the primary lever 26). ) When the longitudinal base end is rotated so as to approach the wiper arm 12 (retainer 16)), the base 36 of the slider 34 and the longitudinal base end of the primary lever 26 are formed in a U-shaped cross section. The retainer 16 is housed in the lumen portion X (the state shown in FIG. 5). Therefore, the base portion 36 of the slider 34 is not exposed to the outside, and the base end portion in the longitudinal direction of the primary lever 26 on the side where the slider 34 is mounted can be minimized. It will be in a lifted state and the appearance will improve.
[0042]
Further, in this case, in this vehicle wiper device 10, the notch 24 corresponding to the slide part 38 of the slider 34 and the buffer part 42 of the holding block 40 is formed on the side wall 18 </ b> A of the wiper arm 12 (retainer 16). When the blade 14 is lifted up, each portion (base portion 36) other than the slide portion 38 of the slider 34 and the posture holding portion 44 of the holding block 40 are completely hidden in the lumen portion X of the wiper arm 12 (retainer 16). In addition, the sliding portion 38 of the slider 34 and the buffering portion 42 of the holding block 40 interfere with the side wall 18A of the wiper arm 12 unnecessarily during the normal wiping operation of the wiper device 10. The movement of the wiper blade 14 that rotates around the support shaft 32 following the shape of the surface to be wiped is obstructed. Theft is not.
[0043]
Furthermore, in the vehicle wiper device 10, when the wiper blade 14 is lifted up by the sliding portion 38 of the slider 34 coming into contact with the lifter 46, that is, the rotational force around the support shaft 32 is applied to the wiper blade 14. When the base portion 36 of the slider 34, the posture holding portion 44 of the holding block 40, or the longitudinal base end portion of the wiper blade 14 (primary lever 26) rotates so as to approach the wiper arm 12 (retainer 16), The posture holding portion 44 of the slider 34 abuts against the back surface of the upper wall 20 of the retainer 16 to lift the wiper arm 12 as it is, and the wiper arm 12 and the wiper blade 14 are held in a state where the rotational force is applied. As described above, since the posture holding portion 44 is lifted up in a state where it is in contact with the back surface of the upper wall 20 of the retainer 16, the distance between the wiper arm 12 and the wiper blade 14 does not fluctuate during lift-up (the wiper arm 12 and Since the lifter is lifted up while maintaining a certain distance from the wiper blade 14), the posture and operation of the wiper arm 12 and the wiper blade 14 at the time of liftup can be seen more smartly.
[0044]
Further, in the vehicle wiper device 10, the slider 34 is formed integrally with the primary lever 26, so that the portion becomes smart and the appearance is improved, and a special screw for attaching the slider 34 as in the past is used. And rivets are not required, the number of parts and the number of assembling processes are reduced, and not only the cost can be reduced as compared with the prior art, but also the parts management of the slider 34 is not required. Moreover, since the slider 34 is not assembled to the wiper blade 14 later, even if the slider 34 is disposed in the inner cavity portion X of the wiper arm 12, the assembly workability is not impaired and the appearance can be improved.
[0045]
Further, in the vehicle wiper device 10, the longitudinal axis φ of the wiper arm 12 and the longitudinal axis φ of the wiper blade 14 coincide with each other in the plan view of the wiper arm 12 and the wiper blade 14, and both longitudinal axes φ The posture holding portion 44 of the holding block 40 is arranged on the top. Therefore, a rotation surface of the wiper blade 14 with respect to the wiper arm 12 (that is, a surface that includes the longitudinal axis φ of the wiper arm 12 and the longitudinal axis φ of the wiper blade 14 and is orthogonal to the support shaft 32), the wiper arm 12 and the wiper blade. The lift-up direction of 14 (the direction in which the vehicle is in contact with and away from the surface to be wiped) coincides with the operating position (point of action) of the rotational force acting on the wiper arm 12 for lifting up on the same plane. It is possible to prevent “twisting force” from acting on each connecting portion (for example, the support shaft 32) such as the wiper arm 12 and the wiper blade 14 during the lift-up.
[0046]
As described above, in the vehicle wiper device 10 according to the present embodiment, not only can the flicker noise caused by the lifted wiper blade 14 be suppressed, but also the appearance can be improved, and the number of parts and the assembly process can be improved. The number can also be reduced.
[0047]
In the preferred embodiment described above, the height of the lifter 46 is set so that when the wiper blade 14 is lifted up, the entire blade rubber 30 of the wiper blade 14 is completely separated from the vehicle (windshield glass). Although described as a configuration in which the height is set so as not to contact, the present invention is not limited to this, and a part of the blade rubber 30 of the wiper blade 14 (for example, the slider 34 is provided with respect to the support shaft 32) even in the lift-up state. It can also be configured such that a part of the tip side opposite to the side) remains in contact with the vehicle (windshield glass).
[0048]
In the case of such a configuration, the effect is inferior in terms of preventing deformation of the blade rubber 30 as compared to the above-described preferred embodiment, but in the lift-up state, almost the entire blade rubber 30 is separated from the vehicle body. However, since the tip of the blade rubber 30 opposite to the side on which the slider 34 is provided with respect to the support shaft 32 is in contact with the vehicle (windshield glass), that is, the attitude holding portion 44 of the slider 34 is the retainer. Since the wiper blade 14 is supported in a state where the two points on both sides of the support shaft 32 are in contact with each other, the lifter blade 14 is in contact with the rear surface of the upper wall 20 and the tip of the wiper blade 14 is in contact with the vehicle. In the up state, the rotation of the wiper blade 14 around the support shaft 32 is prevented. Therefore, the wiper blade 14 can be rotated around the support shaft 32 due to the vibration of the vehicle and the like, and flutter can be prevented, and flutter noise can be suppressed.
