The present invention relates to a spoiler member mounted on a wiper blade for wiping the glass surface of an automobile and a wiper blade having the spoiler member.

In general, when a glass surface is contaminated due to dust or weather conditions in the air, the vision is blurred, which hinders safe driving. Thus, a wiper device is used to wipe the glass surface by driving a wiper blade that is in close contact with the glass surface to secure a watch for the driver's safe driving. Is installed.

Usually, the wiper device comprises a wiper arm that reciprocates within a certain angle by a motor fixedly mounted to a vehicle body, and a wiper blade that is coupled to the wiper arm and wipes the glass surface.

The wiper blade is usually coupled to the frame forming a plurality of link structures, a rubber wiper strip coupled to the frame and elastically contacting the glass surface of the vehicle, and a bracket formed on the frame to connect the wiper blade to the wiper arm. It includes an adapter.

In the conventional wiper blade configured as described above, since a plurality of link members must be assembled with each other to form a frame, a large number of parts has a problem in that a manufacturing process is complicated and noise occurs during operation.

Accordingly, a wiper blade has recently been proposed in which the number of parts is reduced by constructing a frame by one elongated plate. A conventional wiper blade made of a frame formed of one plate may be equipped with a spoiler member to prevent the wiper blade from being lifted from the glass surface due to wind while the vehicle is running, so that the wiper strip of the wiper blade may be tightly adhered to the glass surface.

However, since the shape of the frame to which the spoiler member is coupled is formed to be wider than the width of both end portions, the spoiler member has to be manufactured by injection molding in accordance with the shape of the frame. Therefore, there is a problem in that a large cost is required, such as a mold for injection molding.

The present invention has been made to solve these problems, and an object of the present invention is to provide a spoiler member and a wiper blade having the spoiler member which can be manufactured by extrusion molding, thereby reducing the cost.

According to the present invention for achieving the above object, a wiper blade coupled to the wiper arm of the vehicle to wipe the glass surface, the wiper strip in contact with the glass surface to wipe the glass surface; A frame to which the wiper strip is coupled; An adapter installed at the center of the frame and connected to the wiper arm of the vehicle; A spoiler member coupled to the frame to securely adhere the wiper strip to the glass while driving the vehicle; There is provided a wiper blade comprising a.

The spoiler member may include an upper protrusion formed to protrude in a triangle to receive wind resistance while driving the vehicle, a horizontal extension connecting a lower end of the upper protrusion in a horizontal direction, and a length of the horizontal extension. It is desirable to have a cutout groove formed along the direction.

The spoiler member may further include a bending extension part bent downward from both lower ends of the upper protrusion, and a coupling groove extending in the longitudinal direction to fit the frame by the horizontal extension part and the bending extension part. It is desirable to.

The cutting groove may be formed over the entire length of the horizontal extension to separate the horizontal extension into two.

In addition, the cutting groove may be formed over a portion of the horizontal extension portion so that the horizontal extension portion may not be separated into two.

At this time, the width of the distal end portion of the spoiler member that is not formed with the incision groove, or corresponding to the width of the distal end portion of the frame, so that the spoiler member can be fitted in the frame as it is or have an elastic restoring force It is preferable to set so that.

The spoiler member is preferably manufactured by extrusion molding.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a perspective view showing an assembled state of a wiper blade having a spoiler member according to a first embodiment of the present invention, Figure 2 is a view for explaining the manufacturing process of the spoiler member, (a) Fig. 3 shows a perspective view from above of the spoiler member immediately after being extruded, and (b) shows a perspective view from below of the spoiler member immediately after being extruded. 3 is a view for explaining the manufacturing process of the spoiler member, (a) is a perspective view from above of the spoiler member formed with a cutting groove for assembly, (b) is a spoiler member formed with the cutting groove A perspective view from below is shown. 4 shows the spoiler member, (a) shows a perspective view from above, (b) shows a perspective view from below, and (c) shows a bottom view.

As shown in FIG. 1, the wiper blade according to the present invention includes a frame 10 including one elongated plate, and a rubber wiper strip coupled to the frame 10 and elastically contacting the glass surface of the vehicle. 20, the adapter 30 formed on the frame 10 and connected to a wiper arm (not shown) on the vehicle side, and the wiper strip can be reliably adhered to the glass surface while driving the vehicle by being coupled to the frame 10. And a spoiler member 40 to secure it.

The frame 10 presses the wiper strip 20 against the glass surface with a constant elastic force such that the wiper strip 20 is in close contact with the glass surface of the vehicle. To this end, the frame 10 has a curved metal plate shape. The frame 10 has a shape that gradually widens from both end portions just before reaching the adapter 30.

In addition, the frame 10 is provided with a groove (not shown) in which the wiper strip 20 is fitted. The coupling structure between the frame and the wiper strip may be any conventionally known method, and thus the present invention. This is not a limitation.

As the wiper strip 20, the same as the conventional wiper strip may be used, and thus will not be described in detail. In addition, the adapter 30 may be formed integrally with the frame 10, or may be manufactured separately from the frame 10 and then attached.

According to the present invention, the spoiler member 40, as shown in Figure 2, is extruded in a state having a constant cross-sectional shape is cut to the required length and then manufactured through a simple post-processing.

2 shows a spoiler member 40 in a semifinished state which is extruded and cut to the required length. As shown in FIG. 2, the cross-sectional shape of the spoiler member 40 has an approximately A shape.

The spoiler member 40, the upper protrusion 41 is formed to protrude in a triangle to receive the resistance of the wind while driving the vehicle, and the horizontal extension portion 42 for connecting the lower end of the upper protrusion 41 in the horizontal direction And a bending extension part 43 that is bent and extended downward from both lower ends of the upper protrusion part 41.

Although the shape of the upper protrusion part 41 in the figure is shown as having a triangular cross section, it may have any cross-sectional shape as long as it can perform the function as a spoiler, and the present invention is not limited by the shape.

The horizontal extension portion 42 and the bending extension portion 43 form a coupling groove 44 extending in the longitudinal direction, and the edge portion of the frame 10 is fitted into the coupling groove 44 so that the frame 10 is fitted. The coupling between the spoiler member 40 is made.

By the way, as described above in the prior art, the shape of the frame 10 to which the spoiler member 40 is coupled, because the width of the adapter 30 side is formed wider than the width of both end portions, it is shown in FIG. As described above, the spoiler member 40 may not be coupled to the frame 10 in a state having a constant width.

Accordingly, in order to couple the spoiler member 40 to the frame 10 whose width varies with the length, according to the first preferred embodiment of the present invention, as shown in FIG. 3, the horizontal extension of the spoiler member 40 is shown. (42) Incision grooves 45 are formed over the entire length. Here, of course, this cut groove 45 may be formed during the initial extrusion. This cutting groove 45 allows the horizontal extension 42 to be separated into two.

Since the spoiler member 40 is made of an elastic material, the width of the spoiler member 40 as shown in FIG. 4 is formed by forming the cutout groove 45 in the horizontal extension portion 42. It can be freely widened along. FIG. 4 illustrates the spoiler member 40 in the deformed state fitted to the frame 10, and the frame 10 is omitted for convenience of description.

As described above, since the spoiler member 40 has elasticity, the spoiler member 40 is further brought into close contact with the frame 10 by the restoring force when the width thereof becomes wider, thereby making it possible to reliably maintain the fixed state.

Hereinafter, a spoiler member and a wiper blade having the same according to a second exemplary embodiment of the present invention will be described with reference to FIGS. 5 and 6.

Figure 5 is a view for explaining the manufacturing process of the spoiler member according to a second embodiment of the present invention, (a) is a perspective view of the spoiler member formed with a cutting groove for assembly from above, (b) A perspective view from below of the spoiler member with the incision groove formed therein is shown. 4 is a view showing a spoiler member according to a second preferred embodiment of the present invention, (a) a perspective view from above, (b) a perspective view from below, and (c) a bottom view. It is.

5 and 6, the spoiler member 50 according to the second embodiment extends horizontally in that a cut groove 55 is formed over a part of the entire length of the horizontal extension portion 52. It differs from the spoiler member 40 of the first embodiment in which the cutout 45 is formed over the entire length of the part 42.

The spoiler member 50 according to the second embodiment, like the spoiler member 50 of the first embodiment, has a cross-sectional shape of approximately A shape, and protrudes in a triangle to be subjected to wind resistance while driving the vehicle. The upper protrusion 51, the horizontal extension 52 connecting the lower end of the upper protrusion 51 in the horizontal direction, and the bending extension part 53 extending downward from both lower ends of the upper protrusion 51. Is made of.

The horizontal extension portion 52 and the bending extension portion 53 form a coupling groove 54 extending in the longitudinal direction, and the edge portion of the frame 10 is fitted into the coupling groove 54 so that the frame 10 can be fitted. The coupling between the spoiler member 50 is made.

However, in the spoiler member 50 according to the second embodiment, the cutout groove 55 is formed over a part of the entire length of the horizontal extension portion 52. In the second embodiment, the incision groove 55 is formed to gradually become narrower from one end of the horizontal extension portion 52 of the spoiler member 50 and ends before reaching the other end. As a result, the incision groove 55 is formed only over a part of the entire length of the horizontal extension 52, and the horizontal extension 52 is not divided into two.

In addition, the width of the other distal end portion of the spoiler member 50 in which the incision groove 55 is not formed corresponds to or slightly narrower than the width of the distal end portion of the frame 10, so that it can be inserted as it is or has a slight elastic restoring force. It is desirable to be set to be able to.

According to the spoiler members 40 and 50 according to the first and second embodiments described above, by additionally performing only simple post-processing to form the cut grooves 45 and 55 in the semi-finished product which is cut to a predetermined length after extrusion molding, Instead of costly injection molding, it is possible to produce spoiler members in an inexpensive extrusion process.

Although the spoiler member and the wiper blade having the same according to the present invention have been described with reference to the illustrated drawings as described above, the present invention is not limited to the above-described embodiments and drawings, and is seen within the utility model registration claims. Of course, various modifications and variations can be made by those skilled in the art.
