Description

The present invention relates to a wiper blade apparatus for a vehicle,

The present invention relates to a vehicle wiper blade apparatus, and more particularly to a flat blade type wiper apparatus.

Automotive glass cleaning blade assemblies are commonly used as an automotive comfort device that is installed to remove impurities on the windshield surface of an automobile or remove rainwater to ensure the visibility of the driver of the vehicle, It is one.

Generally, an automobile glass cleaning blade assembly includes a wiper strip slidingly contacted with a glass of an automobile and having rubber elasticity, a support member for resiliently supporting the strip, and a connection for firmly fixing the wiper strip to the wiper arm The assembly includes a retainer and a connecting device. In general, the retainer has a tournament structure to accommodate the contact error between the wiper strip and the automobile's glass due to the difference in curvature of the glass of the automobile between the wiper strip and the retainer. In this tournament structure, there is a space between the wiper strip and the retainer. Recently, as the road conditions have been improved to enable high-speed traveling and the performance of automobiles has been enhanced, problems of conventional automobile glass cleaning blade assemblies have been pointed out. That is, when the wiper is operated during a high-speed traveling of 160 km or more, lifting force acts on the blade assembly for cleaning an automobile glass, thereby failing to properly contact the glass of the automobile. To solve this problem, there is a need to develop a new concept of automobile glass cleaning blade assembly without a retainer structure.

A wiper, which has recently attracted attention for the purpose of preventing the wiper from floating at the time of high-speed vehicle driving, is a so-called "flat blade ". In the flat blade type wiper apparatus, a supporting member (vertebra) for supporting the wiper lip is constructed as a spoiler-integrated lever-integrated type, and a connector device for connecting the wiper arm to the center portion of the supporting member is disposed. An example of such a flat blade type wiper device is disclosed in the Published Patent Application No. 2011-0116521.

However, the conventional flat blade type wiper blade apparatus is not equipped with a spoiler for inducing a flow of air to press the wiper blade apparatus toward the windshield at the time of a high speed running, or even when the spoiler is provided, There is a problem that the continuity is lacking with the connector device and the spoiler function can not be performed effectively at the center of the wiper. That is, since the connector device has a structure to cover one end of the spoiler, the structural continuity of the spoiler and the connector device is cut off, and a step is generated at the overlapping portion, resulting in an unfavorable appearance.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wiper blade apparatus for a vehicle, which is improved in structure to maintain continuity between a spoiler member and a connector device in a flat blade type wiper apparatus.

According to an aspect of the present invention, there is provided a wiper blade apparatus for a vehicle, comprising: a supporting member formed into a long, rod-shaped metal plate;

A connector device disposed at a central portion of the support member and having a rotation axis to which the wiper arm is rotatably engaged and fixed to the support member;

A wiper lip slidingly coupled to the groove portion of the connector device and the spoiler member and contacting the glass of the vehicle to remove foreign matter; And

And an end cap fixed to an end of the support member to prevent the spoiler member from being detached from the support member,

Wherein the spoiler member has a rigid portion and a soft portion made of a material having a hardness lower than that of the rigid portion integrally joined together by double injection,

And the end cap includes a pressure regulator for partially pressing the soft portion of the spoiler member and applying a force to push the spoiler toward the connector device.

The pressure regulating portion may have a cantilever shape.

The pressure regulating portion may include a first pressing portion disposed at the center and a second pressing portion disposed on both sides of the first pressing portion and protruding shorter than the first pressing portion.

And the pressure regulator may have a shape in which the cross-sectional area of the pressure regulator gradually decreases from the end cap toward the connector device.

The pressure regulator may include a ladder-type structure that slidably receives the end portion of the soft portion and has a narrower distance from the connector device toward the end cap.

The wiper blade device for a vehicle according to the present invention is characterized in that the pressure regulating portion always presses the soft portion of the spoiler member so that one end portion of the spoiler member remains in contact with the connector device and the spoiler member and the connector device maintain continuity So that it can be closely adhered to the wiper blade unit and the glass during driving and excellent appearance quality can be maintained.

1 to 7, the vehicle wiper blade apparatus 10 according to the present invention is a wiper blade apparatus belonging to the so-called flat blade type wiper apparatus.

The vehicle wiper blade apparatus 10 includes a support member 20, a connector device 30, a spoiler member 40, a wiper lip 50, and an end cap 60.

The support member 20 is a long member formed in the form of a metal rod. The support member 20 is a member that functions to bring the wiper lip 50, which will be described later, into close contact with the glass surface of the vehicle with a certain rigidity and elasticity. The support member 20 may be made of, for example, carbon steel or stainless steel.

The connector device (30) is disposed at a central portion of the support member. The connector device 30 is provided for mounting a wiper arm (not shown). The connector device (30) is provided with a rotation axis to which the wiper arm is rotatably engaged. The connector device (30) is fixed to the support member (20). The connector device 30 may be composed of a plurality of components. The connector device 30 may be fixed to the support member 20, for example, by caulking, welding or snapping. Both ends of the connector device 30 are configured to have the same appearance as the spoiler member 40 described later.

The spoiler member 40 is disposed on both sides with the connector device 30 interposed therebetween. The spoiler member (40) is slidably coupled to the support member (20). One end of the spoiler member 40, more specifically, the end on the side of the connector device 30 is arranged to face the connector device 30 without overlapping. The spoiler member 40 induces a flow of air such that the spoiler member 40 is pressed against the glass of the vehicle when the vehicle is traveling at a high speed. The spoiler member 40 comprises a rigid portion 42 and a soft portion 44. The rigid portion 42 constitutes a portion for accommodating the wiper lip 50 to be described later. The hard portion 42 is made of a synthetic resin having a relatively high hardness. The soft portion (44) is made of a material having lower hardness than the hard portion (42). The soft portion 44 is made of a synthetic resin material having hardness lower than that of the material constituting the hard portion 42. Therefore, when the external force is applied to the soft portion 44, elastic deformation may partially occur as compared with the hard portion 42. The spoiler member 40 forms a structure in which the rigid portion 42 and the soft portion 44 are integrally coupled by double injection.

The wiper lip 50 is a component that removes foreign matter by contacting the glass of the vehicle. The wiper lip 50 may be made of soft synthetic rubber or natural rubber. The upper portion of the wiper lip 50 is slidably engaged with the groove formed in the connector device 30 and the spoiler member 40. The wiper lip 50 is limited in its longitudinal direction by the support member 20 or an end cap 60 described later.

The end cap (60) is a member that is fitted to both ends of the support member (20). The end cap 60 is provided to prevent the spoiler member 40 from being disengaged from the support member 20. The end cap (60) is fixed to the end of the support member (20). The end cap 60 has a spoiler reference surface 61 on which an end portion of a spoiler member 40 to be described later is supported by design specifications. The spoiler reference surface 61 is a surface on which the end portion of the spoiler member 40 is contactably supported by the end cap 60 when there is no pressure regulating portion 62 described later.

The end cap 60 includes a pressure regulating portion 62. The pressure regulator 62 is disposed to apply a force to partially push the soft portion of the spoiler member 40 and push the spoiler member 40 toward the connector device 30. [ In this embodiment, the pressure regulator 62 may be configured as a cantilever as shown in FIG. It is preferable that the pressure regulating portion 62 has a shape in which the sectional area thereof becomes smaller as the distance from the end cap 60 toward the connector device 30 increases.

The pressure regulating part 62 may include a first pressing part 63 and a second pressing part 64. The first pressing portion 63 is disposed at the center. The second pressing portion 64 is disposed on both sides of the first pressing portion 63. The first pressing portion 63 and the second pressing portion 64 are arranged in parallel to each other. The second pressing portion 64 protrudes shorter than the first pressing portion 63. [ Both the first pressing portion 63 and the second pressing portion 64 press the soft portion 44 of the spoiler member 40 so that the spoiler member 40 is brought into close contact with the connector device 30. [ . The lengths of the first pressing portion 63 and the second pressing portion 64 are different from each other because the length of the spoiler member 40 varies during the manufacturing process, So as to act on the spoiler member 40. That is, when the spoiler member 40 is manufactured longer than the design specification, both the first pressing portion 63 and the second pressing portion 64 press the side surface of the soft portion 44 to cause elastic deformation And the spoiler member 40 is pressed toward the connector device 30 to maintain a state in which the spoiler member 40 is in close contact with the connector device 30. [ When the spoiler member 40 is manufactured to be shorter than the design specification, the first pressing portion 63 mainly presses the side surface of the soft portion 44 to cause elastic deformation, and the spoiler member 40 Is pressed toward the connector device (30) and held in a state of being in close contact with the connector device (30).

Meanwhile, the pressure regulator 62 may be formed in a different shape as shown in FIG. Referring to FIG. 7, the pressure regulator 62 according to another embodiment may be configured to slidably receive an end portion of the soft portion 44. The pressure regulating portion 62 may have a ladder-like structure with a narrower distance from the connector device 30 toward the end cap 60.

Now, the process of assembling the vehicle wiper blade apparatus 10 having the above-described structure and the operation and effect will be described in detail.

First, the connector device 30 is fixed to the central portion of the support member 20. The connector device 30 may be composed of a plurality of components. In this case, some of the components of the connector device 30 may first be fixed to the support member 20 by welding and caulking. And the remaining components can be coupled to the support member 20 at a required point in time. A lower portion of the connector device 30 is provided with a guide groove for receiving the upper portion of the wiper lip 50.

Now, a pair of the spoiler members 40 are slidably engaged from both ends of the support member 20, respectively. The spoiler member 40 is provided with a channel through which the support member 20 is slidably coupled so that the support member 20 and the spoiler member 40 are coupled along the channel. Both ends of the support member 20 are exposed when the spoiler member 40 is engaged.

Now, the end cap 60 is coupled to both ends of the support member 20, respectively. The end cap 60 is engaged with the hole or the groove of the support member 20 so that the end cap 60 is not separated from the support member 20. [

The pressure regulating portion 62 provided on the end cap 60 presses the side surface of the soft portion 44 of the spoiler member 40 to elastically deform the soft portion 44 partially. When a part of the soft portion 44 is elastically deformed, the soft portion 44 has a property of returning to the original shape by the elastic restoring force. Since the pressure regulating portion 62 is protruded from the end cap 60 toward the connector device, in order for the resiliently deformed portion of the soft portion 44 to be resiliently restored, It is necessary to move toward the device 30. So that the spoiler member 40 is pushed toward the connector device 30 naturally. As a result, a pair of spoiler members (40) on both sides of the connector device (30) presses the connector device (30). Therefore, the portion where the spoiler member 40 and the connector device 30 face each other forms a surface in close contact with each other, so that a gap is not generated. As a result, the adjacent portions of the spoiler member 40 and the connector device 30 can form a continuous structure without any gap. As a result, the spoiler member 40 and the connector device 30 are naturally connected to each other, so that no vortex is generated in the course of air flow, so that the wiper lip 50 can contact the glass surface of the vehicle . In addition, there is an advantage that a beautiful appearance can be constituted by maintaining the structural continuity of the spoiler member 40 and the adjacent portion of the connector device 30.

As described above, the vehicle wiper blade apparatus according to the present invention is characterized in that the pressure regulating portion always presses the soft portion of the spoiler member so that one end of the spoiler member remains in contact with the connector device, So that it can be closely adhered to the wiper blade unit and the glass during driving, and the excellent appearance quality can be maintained.

  While the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not to be limited to the details thereof, and various changes and modifications may be made without departing from the scope of the present invention.
