WIPER ARM INTEGRATED WIPER BLADE {WIPER BLADE INTEGRATED WITH A WIPER BLADE}

The present invention relates to a wiper device for a vehicle, and more specifically, to a wiper arm integrally configured by directly connecting the wiper arm and the connection bracket of the wiper blade, which reduces the number of parts and eliminates noise and wiping defects. Relates to a wiper blade.

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. For this purpose, the vehicle is equipped with a wiper system to remove dust and rain on the windshield surface.

In the general configuration of the wiper system, the wiper motor, the wiper link operated by the wiper motor, the wiper arm rotated by the wiper link within a range of an angle, and the center part are fixed to the end of the wiper arm. When the wiper arm is moved, the wiper blade is wiped by wiping the surface of the windshield while moving within a range of angles along the surface of the windshield, thereby removing various dusts and foreign matters on the surface. One such role is the vehicle wiper blade disclosed in US Pat. No. 6,026,537.

1 is a front view showing a wiper blade disclosed in Patent '537. As shown here, the wiper blade 14 is rotatably fixed to the wiper arm 12 by a hinge. To this end, the wiper blade 14 is provided with a main bracket 16 which is hinged to the wiper arm 12, the intermediate bracket 18 is coupled to the main bracket 16 by a hinge 22, The rubber bracket 20 is coupled to the intermediate bracket 18 by a hinge 24. The elastic rubber 26 is fitted to both ends of the rubber bracket 20 by the clips 38 and 39.

The conventional wiper blade having such a configuration is pivotally coupled to the wiper arm by the clip, so that there is a play in the clip portion, which generates noise due to friction with the windshield surface during operation, and at the same time, there is a hard-to-wipe portion. There are many difficulties in securing the forward field of view. In addition, since a clip and a pin for fixing the clip are required, a large number of parts are required and additional assembly processes and assembly time are required to combine them, which causes a cost increase.

The present invention to solve the above problems by integrally configuring the wiper arm and the connection bracket of the wiper blade, there is no need for a separate clip or pin, and the wiper arm-integrated wiper that can prevent the noise and wipe defect caused by The purpose is to provide a blade.

The wiper arm-integrated wiper blade of the present invention for achieving the above object is a drive arm operated by a wiper motor, a pivot shaft operatively coupled to the drive arm via a connecting link, and coupled to the threaded portion of the pivot shaft. A wiper device for a vehicle including a wiper arm and a wiper blade for wiping off foreign matter or rainwater on a windshield surface through a rubber, characterized in that it is integrally formed at the end of the wiper arm through an upper connection bracket.

Hereinafter, a wiper arm integrated wiper blade according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.

Figure 2 is a front view showing a wiper blade according to the present invention, Figure 3 is an enlarged perspective view of the connecting bracket shown in Figure 2, the same parts as the structure of the wiper blade described in Figure 1 denoted by the same reference numerals.

Typically in a vehicle wiper device, the driving force of the wiper motor is transmitted to the wiper arm through the wiper link, and dust or foreign matter on the surface of the windshield as the wiper blade rotates at a predetermined angle by the power transmitted to the wiper arm. Will be removed.

In the vehicle wiper device of such a configuration, in the preferred embodiment of the present invention as a way to prevent noise and wiping defect caused by the clearance of the conventional clip integrally configured the wiper arm and the wiper blade. That is, as shown in Figure 2, by forming the upper connection bracket 16 constituting the wiper blade integrally with the end of the wiper arm 50, the conventional clip or pin is eliminated and the structure is simplified.

Here, the end of the wiper arm 50 is formed to be integrally fixed to the center of the upper surface of the connecting bracket 16 constituting the wiper blade 14. At the time of manufacture, the wiper arm 50 and the connection bracket 16 may be integrally molded, and each of them may be manufactured and then combined by welding or the like. As a result, the connection bracket of the wiper blade may be integrally fixed to the wiper arm or molded integrally as shown in FIG.

The connecting bracket 16 is integrally formed with the wiper arm 50, and the intermediate bracket 18 is fixed to the connecting bracket 16 by pins 22, and the intermediate bracket 18 has a pin ( The rubber bracket 20 is fixed in turn by 24. The rubber 26 is coupled to the rubber bracket 20 by clips 38 and 39.

In the preferred embodiment of the present invention described so far, but the connection bracket is illustrated with respect to the wiper blade integrally configured with the end of the wiper arm, those skilled in the art various modifications without departing from the technical spirit of the present invention It will be understood that modifications, additions, etc. are possible.

According to the present invention described above, by integrally connecting the wiper arm and the wiper blade connecting bracket, integrally formed, by eliminating the clips and pins necessary for the coupling of the wiper blade, the number of parts is reduced, and the assembly time and the number of steps Can reduce manufacturing costs. In addition, in the prior art, a gap was generated in the clip portion for connecting the wiper blade to the wiper arm, so that noise and wiping defects were generated. This does not occur can always maintain a quiet atmosphere, there is an advantage to ensure a clean front view.
