Description
The present invention relates to a vehicle wiper blade, and relates to a vehicle wiper blade which can reduce production costs.
Automotive wiper blades are designed to wipe off debris such as rain, snow and dust on the front and rear windows of the vehicle.
Such a wiper blade for a vehicle may be preloaded with a curvature greater than the curvature of the curved surface of the vehicle glass before being pressed by a wiper arm and a conventional wiper blade which uses a plurality of yokes to fix the wiping rubber. There is a flat wiper blade to which elastic force is applied.
In the case of flat wiper blades, the flat leaf spring is preloaded by bending to have a predetermined curvature.
If some leaf springs are made to have a uniform width and thickness along the length of the wiper blade, the material cost may increase unnecessarily.
In addition, when it is made to have a uniform width and thickness along the longitudinal direction of the wiper blade may not fully correspond to the fact that the pressure is applied to the central portion of the wiper blade by the wiper arm. That is, even if the wiper blade is in close contact with the vehicle glass, a phenomenon in which the wiper blade may be spaced apart from the vehicle glass may occur.
Accordingly, it is an object of the present invention to provide a vehicle wiper blade which can reduce production costs.
Another object of the present invention is to provide a wiper blade for a vehicle which can improve the adhesion with the vehicle glass.
Still another object of the present invention is to provide a vehicle wiper blade which can improve the wiping performance.
According to the present invention, there is provided a vehicle wiper blade, a vehicle wiper blade comprising: a blade support member having an elastic spring extending in a longitudinal direction; A wiping member disposed below the blade support member and in close contact with the vehicle glass and extending in the longitudinal direction to wipe the vehicle glass; A spoiler disposed on an upper side of the blade support member, the spoiler having an air winder wall extending upwardly to catch a wind blowing in a transverse direction; A clip connecting the spoiler and the wiping member along the length direction; A connector for connecting the wiper blade to a wiper arm; A clamp coupled to an intermediate portion of the blade support member and supporting the connector; And a gap member disposed between the clamp and the blade support member such that the curvature of the middle portion of the blade support member is opposite to the curvature of the other portion or the middle portion is substantially flat. Can be achieved by
Here, the gap member may be integrally formed with the clamp.
According to the vehicle wiper blade according to the present invention has the following effects.
First, the material cost can be reduced by forming a plurality of notches on at least one of both side surfaces in the longitudinal direction of the blade supporting member to which the elastic force is preloaded.
Second, the contact force between the wiper blade and the vehicle glass can be varied by selectively distributing a plurality of notches on the blade support member that is preloaded to provide the elastic force to the wiper blade.
Third, the entire wiper blade is in close contact with the vehicle glass along the longitudinal direction, thereby improving the wiping performance.
Fourth, the curvature of the middle portion of the blade support member may be substantially zero, or the curvature may be generated in the opposite direction compared to other portions.
