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 coupled 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 the blade assembly for automobile glass cleaning of such a concept include US Patent No. 6,978,512, PCT Publication WO 2005/000646, and the like.

1 is a view showing a schematic configuration of a blade assembly for cleaning a conventional vehicle glass. FIG. 2 is a schematic view illustrating a connection structure of a support member with a wiper strip removed from the blade assembly for automobile glass cleaning shown in FIG. 1. 3 is a cross-sectional view taken along the line III-III shown in FIG. 1. 1 to 3, a blade assembly 1 for cleaning a vehicle glass in the form of a conventional flat blade includes a wiper strip 2, a support member 3, and a connection 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 5 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 to be in good contact with the glass of the vehicle and at the same time serves to give 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 connecting member 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 portion 4 is provided with a bridge portion 8. The bridge portion 8 is arranged to cross between the support members 3. The lowermost end of the bridge portion 8 is arranged at a position higher than the uppermost end of the wiper strip 2. That is, the bridge portion 8 and the wiper strip 2 are arranged so that interference does not occur. Thus, the wiper strip 2 can move relative to the support member 3 along the longitudinal direction of the support member 3.

The blade assembly 1 for cleaning a vehicle glass having such a structure has some problems. That is, the problem is as follows. First, it is a structure that can flow in the longitudinal direction of the support member 3 of the wiper strip (2). More specifically, the amount of the wiper strip 2 that can flow in the longitudinal direction of the support member 3 is about 5 mm. This amount of flow affects about 0.5% of the wipe area prescribed by law. That is, there is a problem that the area about 0.5% less than the wipe area prescribed by law is wiped off. Second, since the connecting member 4 is coupled to the supporting member 3 by welding, the wiper strip 2 must be assembled after the supporting member 3 and the connecting member 4 are combined. A constraint arises. 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.
