Description

WIPER DEVICE FOR USE IN AN AUTOMOBILE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile wiper device, and more particularly, to a vehicle having a compact structure in which a wiper arm and a wiper blade are operated by rotating a pivot shaft through a first link and a second link that are rotated through a driving link. Relates to a wiper device.

Windshields are fitted on the front of the car to prevent wind from entering 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.

In general, the overall configuration of a wiper device for an operating vehicle includes a drive link operated by a wiper motor, a pivot shaft operatively connected to the drive link via a connecting link, a wiper arm coupled to an upper threaded portion of the pivot shaft, If the wiper arm moves while the center part is fixed to the end of the wiper arm, the windshield surface is wiped while moving within a range of angles along the surface of the windshield, thereby removing various dust and foreign matter from the rain or surface. It consists of a wiper blade to remove it. A typical example of such a configuration is US Patent No. 5,473,955.

In the conventional automotive wiper device having such a configuration, there is a problem in that the overall structure is complicated and its operability is low.

The present invention for solving this problem provides a compact wiper device for a vehicle having a compact structure to operate the wiper arm and the wiper blade by rotating the pivot shaft through the first link and the second link rotated through the drive link. There is a purpose.

Automotive wiper device of the present invention for achieving the above object is in the car wiper device for transmitting the operating force of the wiper motor through the pivot shaft to the wiper arm to operate the wiper blade, the wiper motor is fixed and interposed a plurality of bushes A mounting plate fixed to the vehicle body, a first link operatively coupled to a drive link fixed to the lower end of the wiper motor, a second link coupled to interlock with the first link through a pivot plate, and A pivot shaft to which one end of the pivot plate is fixed and a wiper arm is coupled to the upper end, a pivot housing rotatably supporting the pivot shaft and mounted to the vehicle body through a mounting extension, and both ends of which are fixed to two pivot housings Includes a fixing pipe to which one end of the mounting plate is fixed. And that is characterized.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the vehicle wiper device according to a preferred embodiment of the present invention.

1 is a plan view showing the wiper device of the present invention, Figure 2 is a front view showing the wiper device of the present invention, Figure 3 is a side view showing the wiper device of the present invention.

First, as shown in Figure 1, when the overall configuration of the wiper device according to a preferred embodiment of the present invention, the wiper motor 14 is fixed and the mounting plate 10 is fixed to the vehicle body through a plurality of bushes A first and second links 22 and 24 for transmitting the operating force of the wiper motor 14 to the pivot shaft 32, a pivot housing 30 for rotatably supporting the pivot shaft 32, The mounting portion 10 is coupled to the intermediate portion, and both ends are composed of a fixed pipe 20 to which the pivot housing is coupled.

Next, referring to FIGS. 2 and 3, a motor shaft 16 protrudes from the lower portion of the mounting plate 10, and a drive link 18 is connected to the motor shaft 16. Here, one end of the drive link 18 is connected to the lower end of the motor shaft 16 by a nut, and the other end is connected to one end of the first link 22 by a ball pin 21. Therefore, when the motor shaft 16 starts to rotate by the wiper motor 14, the drive link 18 is rotated in accordance with the rotation of the motor 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 ball pin 26. In addition, one end of the second link 24 is connected to the pivot plate 28 by a ball 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.

The following describes the operation of the wiper device with this configuration.

When electricity is supplied to the wiper motor 14 according to the operation of the wiper switch, the drive link 18 starts to operate while the motor shaft 16 of the wiper motor 14 is rotated. As the first link 22 moves by the operation of the drive link 18, the pivot plate 28 and the second link 24, to which the first link 22 is coupled, begin to interlock.

Accordingly, the pivot shaft 32 on the right side in the drawing starts to rotate by the operation of the pivot plate 28, and the pivot shaft 32 on the left side in the drawing rotates by the operation of the second link 24. The wiper arm, which is coupled to the top of 32, is actuated to allow the wiper blade to rotate along the windshield surface.

According to the present invention described above, since the wiper arm is operated via the first and second links, the structure is simple, excellent in operability, and excellent in assembly strength.
