Description

Wiper blades for automobiles {WIPER BLADE FOR AN AUTOMOBILE}

The present invention relates to an automobile wiper device, and more particularly, to simplify the wiper blade composed of a plurality of brackets, and to form the wiper arm and the wiper arm integrally to reduce the number of parts to reduce the number of assembly processes and manufacturing cost The present invention relates to a wiper blade for an automobile, which can reduce power consumption.

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 wiper blade for automobiles 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, conventionally, a clip and a pin for fixing the clip are required, and since the wiper blade includes a plurality of brackets, such as an intermediate bracket or a rubber bracket, as well as a connecting bracket, a large number of parts are required. Since the process and the assembly time are required, the cost rises.

The present invention for solving the above problems is to configure the wiper arm and the wiper blade integrally, and at the same time to simplify the structure of the wiper blade to reduce the number of parts, assembly time and assembly costs to reduce the manufacturing cost The purpose is to provide a wiper blade.

In the automotive wiper blade of the present invention for achieving the above object, in the wiper device for automobiles to wipe off foreign matter or rain water on the windshield surface through the wiper blade rotated within a predetermined angle by the operation of the wiper motor, And a frame attached integrally to the end of the arm, a clip attached to the lower portion of the frame by a plurality of brackets, and a rubber fitted to the clip.

Hereinafter, a wiper blade for an automobile according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view showing the configuration of a wiper blade according to a preferred embodiment of the present invention, Figure 3 is a cross-sectional view taken along the line A-A in FIG.

Typically, in the wiper device for automobiles, the driving force of the wiper motor is transmitted to the wiper arm through the wiper link, and by the power transmitted to the wiper arm, the wiper blade rotates at a predetermined angle, It will remove foreign substances.

In the above-described automotive wiper device, a wiper arm and a wiper blade are integrally formed in a preferred embodiment of the present invention in order to prevent noise and wiping defects caused by play of a conventional clip. That is, as shown in FIG. 2, the frame 50 is integrally formed at the end of the wiper arm 62, and then the wiper blade 60 is disposed below the frame 50 using the plurality of brackets 54. ) To simplify the overall structure.

In the overall structure of the wiper blade according to the present invention, a frame 50 integrally formed at one end of the wiper arm 60 and a clip fixed below the frame 50 through a plurality of brackets 54. (62) and the rubber (60) which the upper end fits into the clip (62).

Here, the end of the wiper arm 52 is formed to be integrally fixed to the central upper end of the frame 50 constituting the wiper blade. At the time of manufacture, the wiper arm 52 and the frame 50 may be integrally molded, and each of them may be manufactured, and then combined by an appropriate method such as welding.

The plurality of brackets 54 disposed between the frame 50 and the clip 62 may be integrally molded with the frame 50 or, in some cases, molded and attached to a separate part. Here, the clip 62 may be configured as a single piece integrally formed with the bracket 54, or may be formed to have the same length as the rubber 60.

In the configuration of the rubber 60 fitted to the clip 62, the fixing part 64 inserted into the clip 62 and the fixing part 64 are integrally formed so as to be movable, And a contact portion 66 in sliding contact with the surface.

As shown more clearly in FIG. 3, the fixing portion 64 of the rubber 60 is fitted to the clip 62 so as not to be separated, and the contact portion 66 integrally formed at the lower portion of the fixing portion 64 is approximately. It has a triangular shape. In addition, although not shown, it is preferable to insert a belt spring for increasing the rigidity of the rubber 60 in the fixing portion 64.

In the assembly, the entire rubber 60 may be pressed in the longitudinal direction and pushed in the state in which the tip of the fixing part 64 of the rubber 60 is inserted into the clip 62. At this time, by minimizing the tolerance between the fixing portion 64 and the clip 62 to be forcibly fitted, it is fixed without using a separate fixing means, and at the same time replacing only the rubber 60 when replacing the wiper blades It is desirable to prevent waste of resources.

In the preferred embodiment of the present invention described so far, but exemplified with respect to the wiper blade formed integrally with the frame at the end of the wiper arm, those of ordinary skill 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. For example, it is also possible to construct a wiper arm-integrated wiper blade with a simplified structure by extending one end of the frame and then forming a hole in the extension portion and directly engaging the pivot axis.

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.
