Description

Fixed bracket for pivot housing for wiper device {MOUNTING BRACKET FOR A PIVOT HOUSING OF WIPER SYSTEM}

The present invention relates to a pivot housing for a wiper device, and more particularly, to the I-beam shape of the fixed pipe coupled between the two pivot housings of the pivot housing for the wiper device to increase the coupling strength and reduce the weight of the product It relates to a fixing bracket.

The windshield is fitted to the front of the car to prevent the wind or rain from blowing from the front while driving. When dust or dirt accumulates on the surface of the windshield, it is difficult to secure the view in front of the windshield. In particular, when driving in snow or rainy areas, it is necessary to remove the moisture on the surface of the windshield quickly. Can be. To this end, the vehicle is provided with a wiper device, which can remove dust and rain water on the surface of the windshield.

FIG. 1 is a view illustrating a general vehicle wiper device. In the overall configuration thereof, a wiper motor 14 is fixed and a mounting plate 10 fixed to a vehicle body through a plurality of bushes, and a wiper motor 14 First and second links 22 and 24 for transmitting an actuation force to the pivot shaft 32, a pivot housing 30 for pivotally supporting the pivot shaft 32, and an intermediate portion of the mounting plate ( 10) is coupled to both ends of the fixed pipe 20 is coupled to the pivot housing.

A drive shaft 16 protrudes from the lower portion of the mounting plate 10, and a drive link 18 is connected to the drive shaft 16. Here, one end of the drive link 18 is connected to the lower end of the drive shaft 16 by a nut, and the other end is connected to one end of the first link 22 by a hinge pin 21. Therefore, when the drive shaft 16 starts to rotate by the wiper motor 14, the drive link 18 is rotated according to the rotation of the drive shaft 16 to operate the first link 22.

On the other hand, the other end of the first link 22 is coupled to the pivot plate 28 by a hinge pin (26). In addition, one end of the second link 24 is connected to the pivot plate 28 by a hinge pin 27. The other end of the second link 24 is connected to the opposite pivot plate 28. The lower end of the pivot shaft 32 is press-fitted to the other end of the pivot plate 28.

Although not shown at the top of the pivot shaft 32, a wiper arm for operating the wiper blade is engaged. In addition, the pivot shaft 32 is rotatably mounted in the pivot housing 30. Mounting extension 36 is integrally formed in pivot housing 30. This mounting extension is firmly fixed to the vehicle body via the bush.

2 is a cross-sectional view showing a conventional fixed pipe. As shown here, it can be seen that the fixed pipe 20 has a circular cross section.

In the conventional pivot housing for the wiper device having such a configuration, since the cross section of the fixed pipe is circular, there is a problem that the bonding strength is low and the weight of the product is high.

The present invention for solving the above problems is to provide a fixing bracket of the pivot housing for the wiper device to reduce the weight while reducing the weight while maintaining the same coupling strength by changing the shape of the fixed pipe.

The fixing bracket of the wiper device pivot housing of the present invention for achieving the above object is a pivot shaft which is operated by a wiper motor via a plurality of links, and a pivot that is mounted on the vehicle body while supporting the pivot shaft rotatably. A vehicle wiper device comprising a housing, a wiper arm coupled to an upper end of a pivot shaft, and a wiper blade fixed to the wiper arm to rotate within a range of a predetermined angle along the surface of the windshield. It is characterized by including.

Hereinafter, with reference to the accompanying Figures 3 and 4 will be described in detail with respect to the fixing bracket of the pivot housing for the wiper device according to a preferred embodiment of the present invention, the same parts as the conventional structure described in Figures 1 and 2 The same code is used.

3 is a cross-sectional view showing a fixed pipe of the present invention, Figure 4 is a perspective view of the fixed pipe shown in FIG.

As also illustrated in FIG. 1, when the configuration of the vehicle wiper device is schematically illustrated, a wiper motor, a pivot shaft operated by the wiper motor via the first and second links, and the pivot shaft are rotatably supported. It comprises a pivot housing mounted to the vehicle body, a wiper arm coupled to the upper end of the pivot shaft, and a wiper blade fixed to the wiper arm to rotate within a range of a predetermined angle along the surface of the windshield.

In the pivot housing 30 having such a configuration, the I-shaped fixed pipe 50 is illustrated in the preferred embodiment of the present invention as a method for preventing rain water from being introduced from the outside.

The I-shaped fixed pipe 50 is composed of a vertical extension portion 52 and vertical horizontal extensions 54 and 56 coupled to the upper and lower portions of the vertical extension portion 50. Here, the vertical horizontal extension portion 54, 56 is fixed to the vertical extension portion 50 by welding or the like.

As described above, when the fixed pipe 50 of the present invention has an I shape, when the strength of the I-beam is analyzed, the bonding strength is increased because the cross-sectional area is larger than that of the conventional circular pipe, and in the case of having the same bond strength It can be seen that this is reduced.

In the preferred embodiment of the present invention described so far, but illustrated with respect to the coupling structure having the I-beam fixed pipe, those skilled in the art without departing from the technical spirit of the present invention various modifications, changes, It will be appreciated that additions and the like are possible.

According to the present invention described above, by adopting the I-shaped fixed pipe can increase the bonding force and reduce the weight of the product.
