The present invention relates to a blade assembly for automobile glass cleaning, and more particularly, a connection structure of a support member for supporting a wiper strip of a blade assembly for automobile glass cleaning, to which a flat blade having a retainer and a blade integrally applied is applied. It is about.

The blade assembly for car glass cleaning is a vehicle's convenience and active safety device, which is generally installed to remove foreign objects or rainwater from the windshield surface of the car to secure the driver's view. One.

In general, a blade assembly for cleaning a glass of a car is a wiper strip having rubber elasticity in sliding contact with a glass of a vehicle, a support member for elastically supporting the strip, and a connection for firmly fixing the wiper strip to a wiper arm. The assembly includes a retainer and a connecting device. In general, the retainer has a tournament structure in order to accommodate the contact error between the wiper strip and the glass of the vehicle due to the difference in curvature of the glass of the automobile between the wiper strip and the retainer. This tournament structure has a space between the wiper strip and the retainer. Recently, road conditions have been improved to enable high-speed driving, and as the performance of automobiles has been advanced, problems of the conventional blade assembly for cleaning glass for automobiles have been pointed out. That is, when the wiper is operated during a high-speed driving of more than 160km, the lifting force acts on the blade assembly for cleaning the glass of the car, so that the contact with the glass of the car is not made properly, thereby preventing the wiping role from being performed properly. In order to solve this problem, research has been conducted on a new concept of a vehicle glass cleaning blade assembly called a flat blade without a retainer structure. Prior arts related to blade glass assembly for automobile glass cleaning of such a concept include US Patent No. 6,836,927, US Patent No. 6,668,419.

1 is a view showing a schematic configuration of a blade assembly for cleaning a conventional vehicle glass. FIG. 2 is a partially enlarged view of a portion “A” shown in FIG. 1. 1 and 2, a blade assembly 1 for cleaning a vehicle glass in the form of a conventional flat blade includes a wiper strip 2, a supporting member 3, and a connecting member 4.

The wiper strip 2 comprises a wiper lip 6 and a groove 7. The wiper lip 6 is a part which is installed in sliding contact with the glass of the vehicle. The groove 7 is formed on the side of the body part integrally extending from the wiper lip 6. The groove 7 is usually provided with a pair. The grooves 7 are formed on the side of the body of the wiper strip 2 and extend in the longitudinal direction of the wiper strip 2. The support member 3 is made of a metal material having a spring elasticity. The support member 3 generally has a strip shape. A part of the supporting member 3 is accommodated in the groove 7. The other part of the support member 3 is exposed out of the groove 7. The support member 3 supports the wiper strip 2 so as to be in good contact with the glass of the vehicle and at the same time serves to impart stiffness to the wiper strip 2.

The connecting member 4 is disposed at both ends of the supporting members 3 to connect the supporting members 3 to each other. Therefore, when two supporting members 3 are provided, two connecting members 4 are required. Each of the connecting members 4 is welded to the supporting members to connect the supporting members 3 in a state where they are coupled to each other. The connecting member 4 is provided with a bridge portion 8. The bridge portion 8 is arranged to cross between the support members 3. On the bridge portion 8 of the connecting member 4 disposed at a position far from the wiper arm among the connecting members 4, a tongue-like strip fixing protrusion extending integrally from the bridge portion 8 9) is provided. The strip fixing protrusion 9 is pressed onto the wiper strip 2 so that the wiper strip 2 is limited in relative movement with respect to the connecting member 4. That is, relative movement in the longitudinal direction of the support member 3 with respect to the support members 3 relatively fixed to the connecting member 4 is limited. The reason for limiting the one-way movement of the wiper strip 2 as described above is to ensure the windshield wiping area regulated by the law of the blade assembly 1 for car attraction cleaning. When the wiper strip 2 is flowed during operation, there is a problem in that an area about 0.5% smaller than the legally defined wiping area FMVSS B-Zone is wiped.

However, this conventional structure has some problems. That is, since the bridge portion 8 is fixed to the support member 3 by welding, the wiper strip 2 must be assembled after the support member 3 and the connection member 4 are combined. Constraints occur. When the wiper strip 2 and the support member 3 are first joined and then the connecting member 4 is joined to the support member 3 by welding, the wiper strip 2 is damaged by a welding flame or the like. There is a problem that you may wear. In addition, there is a problem that the tongue-shaped strip fixing protrusion 9 damages the wiper strip 2 and thus adversely affects the durability of the wiper strip 2.

On the other hand, the structure disclosed in the US Patent No. 6,668,419, another conventional invention is a structure using a separate peg (peg) to maintain the support member at a constant interval, there is a problem that the number of parts and the structure itself is complicated.

That is, the connection member is elastically deformed when it is fitted to the support members in the fixing portion, the compressive elastic restoring force is present in the state coupled to the support members (30).

The connecting device 50 is disposed at the central portion in the longitudinal direction of the support members 30. The connecting device 50 is relatively fixed to the support members 30. The connection device 50 is coupled to the wiper arm 55, one end of which is rotatably fixed. The other end of the wiper arm 55 is pivotally coupled to a wiper motor module (not shown) fixed to the vehicle body of the vehicle.

The operation of the blade assembly 10 for automobile glass cleaning including such a component will be described in detail.

First, the assembly process of the glass cleaning blade assembly 10 will be described. The support members 30 are respectively approached from both sides of the groove 25 of the wiper strip 20. In a state where the support member 30 is inserted into the groove 25, the connection member 40 is brought close to one end of the support member. Both sidewalls of the connection member 40 slide so as to correspond to the widthwise outer edges of the support members 30. Then, the coupling protrusion 44 provided in the connection member 40 is fitted into the coupling hole 36 provided in the support member 30. In this process, the guide portion 46 provided with the coupling protrusion 44 serves to smoothly combine the coupling protrusion 44 and the coupling hole 36. In addition, the interval maintaining jaw 42 provided in the connection member 40 is fitted into the interval maintaining part 34 provided in the support member 30. The gap maintaining portion 34 is in the shape of a groove, and the gap maintaining jaws 42 are coupled to both side walls of the groove, respectively. Therefore, the gap between the support members is kept constant in a state where the gap maintaining part and the gap maintaining jaw are coupled. Therefore, in the state in which the two connecting members are coupled to both side ends of the support members, there is an effect that the distance between the support members is kept constant.

As such, in the state in which the connection member 40 and the support member 30 are coupled, the behavior of the wiper strip 20 in the fixing part 100 and the slide part 200 is changed.

In the fixing part 100, the locking jaw 27 of the wiper strip 20 is caught by the locking part 32 of the support member 30, so that the wiper strip 20 with respect to the support member 30. Relative movement becomes impossible. In addition, in the fixing part 100, the thickness of the neck 28 of the wiper strip 20 is greater than the shortest distance between the inner surfaces of the supporting members 30 disposed in the fixing part 100. Therefore, the neck 28 of the wiper strip 20 in the fixing part 100 is in a compression elastic deformation state by the inner surface of the support members 30. As a result, the wiper strip 20 has the same effect as that fixed relative to the support member 30.

Meanwhile, in the slide part 200, the shortest distance between inner surfaces of the support members 30 is wider than the thickness of the neck 28 of the wiper strip 20. Therefore, the wiper strip 20 is relatively movable with respect to the support member 30. As a result, a portion of the wiper strip 20 disposed on the fixing part 100 is fixed to the supporting member 30, and the remaining portion of the wiper strip 20 is disposed on the slide part 200. It is possible to move relative to. The wiper strip 20 is made of a material having rubber elasticity. Thus, if the vehicle glass cleaning blade assembly 10 is in a state of being mounted on a windshield of an automobile such as a passenger car, when the vehicle glass cleaning blade assembly 10 is operated, its length is reduced by friction with the glass. The wiper strip 20 can be stretched in the direction. In this process, since the expansion and contraction of the wiper strip 20 does not occur in the fixing part 100, the boundary line of the wiper strip 20 located on the outer side of the wiping glass area does not change. These outer borders play an important role in ensuring the legal wipe area. Therefore, if the outer boundary line does not change, it is possible to ensure the legal wiping area of the vehicle glass.

In addition, since the coupling structure of the support member 30 and the connection member 40 is a detachable structure rather than a permanent coupling such as welding, there is an easy assembly effect. In addition, the gap holding portion 34 and the gap holding jaw 42 are located at both ends in the longitudinal direction of the support member 30, there is an effect that the assembly state is good. In addition, since the coupling of the locking jaw 27 and the locking portion 32 does not damage the wiper strip 20, the durability of the wiper strip 20 may be improved.

In the embodiment of the present invention, the support member is a section in which the relative movement is not possible relative to the wiper strip in the longitudinal direction, the slide is a section in which the support member is relatively movable relative to the wiper strip in the longitudinal direction Although described as including a portion, even if the fixing portion and the slide portion is not limited to the section can achieve the object of the present invention.

In the embodiment of the present invention, the gap holding portion has a groove shape in which the longitudinal direction of the support member is open, and the gap holding jaw is described as being a projection to be in contact with both sidewalls of the groove shape. The object of the present invention can be attained even when the protrusion is protruding in shape and the gap retaining jaw is in the shape of a concave groove.
