Description

Bar Roller Structure Contacts With Rail in Regulator for Door Window Glass Up-Down}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller structure for moving a window glass of a vehicle door up and down to be built into the rail when the X-bar is connected to the rails, in particular the X-bar is operated by a motor. The present invention relates to a rail contact bar roller structure in a door window glass regulator for lowering the rail and sliding resistance and improving the durability and reducing the occurrence of noise due to malfunction.

As is well known, a regulator is provided between the inner and outer panels of the vehicle door to raise and lower the window glass, so that the user can freely open and close the window glass from the door as needed.

As for the regulator having an X-type bar among the door window glass lifting / lowering regulators which play such a role, the X-type bar 2 operated by the motor 1 points to the hinge shaft 3 as shown in FIG. The free end and both ends of the X-shaped bar (2) are slid smoothly in the frame of the rail (4) to help the ascending and descending of the X-shaped bar (2). The window glass installed at the end of the type bar 2 is raised and lowered.

Here, the connection between the X-shaped bar (2) and the rails (4) is usually used with a roller, which is divided into a large roller and a square roller, the double circular roller has a small contact surface with the rail The sliding resistance is small and has a good influence on the operating current time of the motor, but when this contact surface is worn, the play with the rail increases, which adversely affects the operation joint, while the rectangular roller is advantageous for the play because of the large contact surface. If this is not done properly, severe sliding resistance is generated, causing operability problems.

That is, since the conventional rectangular roller has a large contact area of the roller 105 which is embedded in the rail 4 and is slid as shown in FIG. 4, the sliding resistance, which is a natural sliding resistance, is increased, so that smooth lubrication is not guaranteed. After all, it had a problem of lowering the performance.

Accordingly, the present invention has been invented to solve the conventional problems as described above, and the rectangular roller connected to the bar operated by the motor is reduced sliding resistance with the rails, so that smooth operation is achieved, durability and operation of the parts It is an object of the present invention to provide a rail contact bar roller structure in a door window glass regulator for reducing a current and reducing occurrence of parts separation.

The present invention for achieving the above object is the one end of one bar of the X-shaped bar connected to the drive shaft of the motor and both side ends of the other bar connected to the hinge axis point to each of the rails and squares corresponding to them In the door window glass lifting regulator which is connected via a roller, a plurality of horizontal and vertical grooves intersect the upper and lower surfaces of the rectangular rollers connected to the bars and the roller shaft to be embedded in the rails to fill the lubricant. Formed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the overall structure of the window glass lifting and lowering regulator of the door to which the present invention is applied, and FIG. 2 is a side view and a front view of a rectangular roller in part A of FIG. 1.

According to the present invention, both ends of one side of one bar 2a of the X-shaped bar 2 connected to the drive shaft of the motor 1 and the other side of the other bar 2b connected to the hinge shaft 3 as points are provided. (4) and the square roller (5) is connected to the door window glass lifting regulator, the bar (2a, 2b) and the roller shaft (6) is connected via a medium in each rail (4) A plurality of horizontal and vertical grooves 8 are formed in the contact upper and lower surfaces 7a and 7b of the built-in rectangular roller 5 to fill the lubricating oil.

Here, the rectangular rollers 5 are connected to the installation tips of the X-shaped bar 2 via the roller shaft 6 when the rectangular rollers 5 are installed in each rail 4, and the rectangular rollers 5 The groove 8 in the same direction as the movement direction formed on the upper and lower surfaces 7a and 7b acts to prevent grease, which is lubricant, from being pushed to one side by the movement of the square roller 5, and the groove 8 perpendicular to the movement direction. The lubricating oil is always kept in the square roller 5 so as to prevent lubricating oil degradation due to durability.

Therefore, in the present invention, the X-type bar 2 operated by the motor 1 is moved up and down while sliding smoothly along the rail 4 to raise and lower the window glass at the door.

As described above, the present invention improves durability while reducing sliding resistance when the X-type bar is operated in contact with the rail, and further improves the merchandise by reducing the occurrence of joints due to malfunction.

Claims (1)

One end of one bar 2a of the X-shaped bar 2 connected to the drive shaft of the motor 1 and both ends of the other bar 2b connecting the hinge shaft 3 to the point are provided with the rails 4.
