Description

Car Wiper Containment

The present invention relates to a wiper containment device. In particular, when the wiper blade used in an automobile is turned off, the present invention can be stored under the window glass to improve the appearance of the vehicle, and to simplify the structure and reverse the link. The present invention relates to a vehicle wiper containment device capable of significantly reducing noise generated by rotation.

In general, the wiper device employed in the vehicle is to wipe the surface of the front or rear window glass to prevent the driver's vision from being obstructed when driving in the rain, and the conventional wiper device is a wiper in the process of turning off the wiper blade. A wiper enclosure for storing the blade under the window glass and an auto stop device for adjusting the stop position of the wiper blade are provided.

Such a wiper enclosure requires about 360 ° of reverse rotation during off operation of the motor. In order to store the above wiper, a cam method and an articulated link method are employed as a power transmission mechanism for transmitting the rotational force of the wiper motor to the wiper blade.

In addition, a conventional articulated link type vehicle wiper containment apparatus is disclosed in Japanese Patent Application Laid-open No. Hei 4-51853. Referring to the accompanying drawings, FIGS. 1 to 5, the motor output shaft 10 is rotated. The first plate 12 rotated together, the second plate 14 is axially coupled to the end of the first plate 12 by the connecting shaft 42 and interlocked with each other, the second plate 14 is seated A first and second disk members 26 and 24 rotated independently of each other according to the rotation thereof, a link 16 connected to the first disk member 26 to transmit the rotational force to the wiper blade 20, The cover 72 is coupled to the second plate 14 to accommodate the first and second disk members 26 and 24 and has a predetermined space.

In more detail, the first and second plates 12 and 14 have a structure in which the wiper motor rotates at a predetermined angle when the wiper motor rotates forward.

In addition, the wiper blade 20 is formed by the protrusions 68 of the first disk member 26 and the grooves of the second disk member 24 when the motor rotation is in the reverse direction. When reaching a predetermined position, the support grooves 32 provided with mutually matching fitting grooves 52, 54, 56, and 58 are provided at predetermined portions of the outer circumferential surface, and protrude to a predetermined size on the upper surface of the second plate 14. It has a structure that is axially coupled to.

In addition, one end is supported on the outer circumferential surface of the first and second disk members 26 and 24 in the inner space of the cover, and the other end thereof is a stopper 22 supported by the guide member 70 fixed to the upper surface of the first plate 12. Has a structure that is provided.

The stopper 22 is a movable piece 78 which is elastically biased in one direction by a spring member 60 having a predetermined elastic force and slides to the inner circumferential surface of the guide member 70 when the motor rotates, and the moving piece 78. The pin 82 is coupled to the fixing piece 80 is slid to the outer peripheral surface of the first and second disk members (26, 24).

In the guide member 70, grooves 34 and 36 are provided on both sides of the inner circumferential surface having a predetermined curvature. Reference numerals 16 and 18 denote a link for transmitting the rotational force of the wiper motor to the wiper blade 20, and “17” denotes a groove provided in the inner circumferential surface of the link for engagement with the second disk member 24, &Quot; 62 " represents a projection provided to protrude on the outer circumferential surface of the second disk member 24 for coincidence assembly with the groove 17.

In the conventional wiper enclosure having such a configuration, when the driver turns off the wiper motor, the motor rotates at a low speed for a predetermined time and then the motor is rotated back when the wiper blade 20 reaches a predetermined position for storing the wiper.

Referring to the operation process for transmitting the forward and reverse rotational power of the wiper motor in this regard, first, the first plate 12 is rotated by the rotational force of the motor during the forward rotation of the wiper motor, and then the first plate ( The second plate 14 connected with 12) is rotated interlocked with a constant angle around the connecting shaft 42.

At this time, the angles of the first and second plates 12 and 14 form a certain angle even while being rotated, which means that both ends of the stopper 22 are formed on the inner circumferential surface of the guide member 70 and the first and second disk members 26 and 24. This is because it is supported and fixed to the outer circumferential surface of the c).

As the second plate 14 rotates, the first and second disk members 26 and 24 rotate about the support shaft 32, and the rotational force is transmitted to the link 16.

On the other hand, when the wiper motor is rotated in reverse, it is bent by the frictional resistance between the wiper blade 20 and the window glass, so that the angles of the first and second plates 12 and 14 have approximately 180 °, so that the length of the joint becomes longer. Thus, the wiper blade 20 can be stored under the window glass.

Referring to the operation process at this time, the fitting grooves 52, 54, 56, 58 of the first and second disk members 26, 24 are matched by the frictional force transmitted from the wiper blade 20, and then the stopper ( While the fixing piece 80 of the 22 is partially accommodated into the fitting grooves 52, 54, 56, and 58, the moving piece 78 leaves one of the recesses 34 of the guide member 70, and the inner peripheral surface thereof is removed. Sliding along.

Then, the moving piece 78 of the sliding stopper 22 is moved to the other recess 36 of the guide member 70 is locked.

Accordingly, since the angles of the first and second plates 12 and 14 are changed, the angles of the links 16 and 18 and the wiper blade 20 are changed, and the wiper blade 20 is lowered below the window glass. Come.

That is, in the conventional wiper containment device, since the articulated link is bent by the friction force of the window glass and the wiper blade 20 when the motor rotates in reverse, the length of the link is increased, so that the wiper blade 20 is moved into the engine room hood. It is stored.

The conventional wiper enclosure described as described above has a useful function of improving the appearance function by storing the wiper blade under the window glass during the off operation of the wiper, but has the following problems.

First, when the stopper slides on the inner circumferential surface of the guide member during the reverse rotation of the motor, impacts are generated when the locking is coupled from the one groove to the other groove.

Therefore, there is a disadvantage that the noise due to the impact caused by the passenger's ear.

Second, due to the impact generated between the stopper and the guide member during the reverse rotation of the motor, there is a problem that causes the early wear and breakage of the parts to reduce the durability.

Third, the number of parts due to the wiper containment is increased, which leads to a problem in that the cost rise and the assembly performance are deteriorated.

The present invention has been devised in view of the above-mentioned problems, and its purpose is to reduce the number of parts required for wiper storage and to reduce the impact of joints generated when the motor rotates in reverse. To provide an enclosure.
