Description

The X-Type Arm Regulator of a Car Door Window Reflects Glass Curvature}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door window regulator, and more particularly, to an X-type arm door window regulator for driving up and down a door glass having curvature.

As shown in FIG. 1, the X-type arm regulator includes a power motor 130, a drive gear 110 that receives rotational force of the power motor, a sector gear 120 meshed with the drive gear 110, and a power motor 130. And an X-type arm that connects the sector gear 120 and the door glass 200, and interlocks with the sector gear 120 via the drive gear 110 according to the rotational driving direction of the power motor 130. FIG. As the X-type arm crosses the letter X, the door glass 200 is raised and lowered.

In order to raise or lower the door glass 200 by the cross movement of the X-shaped arm X, two rotatable sliders 160 fixed to the ends of the driving arm 140 and the auxiliary arm 150 of the X-type arm, respectively. , 170 should be moved along the guide rail 100 for fixing the door glass 200 by the glass holder.

In this case, when the door glass 200 having the curvature is raised or lowered, the first and second sliders 160 and 170 move along the linear trajectory of the guide rail 100, as shown in FIG. 2. The supporting guide rail 100 tries to operate in the vertical direction, and the door glass 200 which forms a curved surface along the shape of the curved door frame as shown in FIG. 3 is the same as the curved surface of the door frame. Since the vehicle moves along the trajectory, the gap between the inner and outer panels of the door should be wide enough to consider the difference of the trajectory, and the wide gap may be a factor of generating wind noise of the vehicle.

In addition, when the door glass 200 is opened and closed, the movement of the door glass 200 and the guide rail 100 does not coincide with each other, and thus a force acts toward the indoor or outdoor side when the door glass 200 is opened or closed. In this case, friction may occur between the weather strip and the door glass 200 which prevents foreign substances such as rainwater from entering the door, thereby lowering the door sealing property, which may reduce durability and noise of components constituting the door. It causes a problem such as this.

Patent No. 10-0868167 proposes a stop means for limiting the maximum amount of lift of the door glass by stopping the rotation of the sector gear connected to the X-type arm at a certain rotational position to prevent permanent deformation of the lip of the door outer channel. In order to prevent deterioration caused by the gap between the door outer channel and the door inner weather strip, it did not reduce or eliminate the cause of gap between the door glass and the guide rail.

Korean Patent Laid-Open Publication No. 2002-38215 discloses a door window regulator composed of an X-type arm which allows a driving arm and an auxiliary arm to rotate with each other. An X-type arm regulator is proposed to move the X-type arm along the curvature of the door glass during vertical operation.

However, the present invention has a problem that the door glass lifting action is not smooth due to the hinge when the driving arm is operated, and assembly and repair due to the increase in the number of parts are not easy.
