Description

WIPER BLADE {WIPER BLADE}

The present invention relates to a wiper blade, by coupling a pair of rail springs to the wiper strip supported by the body spring, the pressure of the wiper arm is evenly transmitted to the wiper strip so that the wiper strip can be evenly adhered to the entire vehicle glass surface. Relates to a wiper blade.

In general, when a glass surface is contaminated by snow or rain due to air dust or various foreign matters or weather conditions, it is difficult to secure a vision, which hinders safe operation. · A car wiper device is installed to wipe off rain and foreign objects.

The vehicle wiper device wipes the glass surface of the vehicle and has a wiper blade having an adapter coupling portion, an arm of the length member coupled to the adapter coupling portion of the wiper blade, one end of which is connected to the arm of the length member, and the other end of the motor is connected to the motor. It consists of a ring cage that transfers rotational power to the reciprocating motion of the wiper blades.

Here, in the wiper blade, a wiper strip made of a soft rubber material is generally supported on the body spring, and the wiper strip contacts the glass surface by the pressure of the arm, and the water or foreign matter on the glass surface is moved to the edge of the glass surface according to the pivoting motion of the arm. It is cleaned by pushing it.

In recent years, the wiper device for vehicles has been gradually increasing the pressure of the arm. Therefore, a wiper blade made of a single wide body spring is being developed to complement a pair of narrow body springs that have been used in the past.

The conventional wiper blade is provided with a wiper strip made of a soft rubber material in close contact with the glass surface of the vehicle, a body spring having a curvature corresponding to the vehicle glass surface in the longitudinal direction and elastically supporting the wiper strip, and a central portion of the body spring. It has an adapter coupling that is coupled to the adapter connected with the wiper arm.

However, the conventional wiper blade has a problem that the pressure transmitted from the wiper arm is not evenly distributed to the wiper strip through the body spring, so that the wiper strip is not evenly adhered to the entire vehicle glass surface.

That is, the pressure of the wiper arm is concentrated at the center of the body spring so that the center portion of the wiper strip is tightly adhered to the glass surface, but both ends of the wiper strip are inferior in adhesion with the glass surface.

Therefore, when the wiper blade moves the vehicle glass surface by the operation of the wiper arm, only the portion where the center portion of the wiper strip passes from the glass surface is wiped evenly.

The present invention has been made to solve the above problems, by providing a spring force to the wiper strip by coupling a pair of rail spring to the wiper strip supported by the body spring, the pressure transmitted from the wiper arm through the body spring It is an object of the present invention to provide a wiper blade which is dispersed in the wiper strip and the distributed pressure is uniformly transmitted to both ends of the wiper strip through the rail spring, thereby improving the wiping performance of the vehicle glass surface.

In addition, by providing a plurality of engaging pieces for supporting the wiper strip in the body spring, and supplementary engaging pieces in the end cap to secure both ends of the body spring and the wire strip to improve the assembly of the body spring and the wiper strip. The purpose is to provide a wiper blade.

The present invention for achieving the above object, in the wiper blade mounted to the adapter is connected to the wiper arm, the first rail groove and the second rail groove are formed on both sides along the longitudinal direction at intervals, respectively, A wiper strip for wiping the glass surface; A pair of rail springs received in each of the first rail grooves of the wiper strip to provide elastic force to the wiper strip so that the wiper strip is in close contact with the glass surface; And a body spring having an adapter coupling portion coupled to the adapter and at least one pair of locking pieces each of which holds the pair of second rail grooves.

The locking piece may further include a protrusion protruding downward from the plate surface of the body spring toward the wiper strip; It is characterized in that it comprises a bent portion extending from the protrusion and coupled to the second rail groove.

In addition, each end of the body spring, characterized in that it further comprises a pair of end caps for fixing the wiper strip and the body spring.

As described above, according to the present invention, the pressure transmitted from the wiper arm is distributed to the wiper strip through the body spring, and the distributed pressure is uniformly transmitted to both ends of the wiper strip through the rail spring, so that the wiper strip is entirely in the vehicle glass surface. By evenly adhering to the glass, the wiping performance of the glass surface can be improved.

In addition, by providing a plurality of engaging pieces for supporting the wiper strip in the body spring, and supplementary engaging pieces in the end cap to secure both ends of the body spring and the wire strip to improve the assembly of the body spring and the wiper strip. have.
