The present invention relates to a structure of a window regulator of a door for a vehicle, and more particularly, to a structure of a window regulator of a door for a vehicle to ensure safety when lifting the window regulator of the vehicle door.

The door glass elevating system, which is one of systems for forming a door of a vehicle, welds the chassis frame 2 to the door inner panel 1 and fixes the window regulator 3 to the door inner panel, as shown in FIG. 1. Fix it to (1).

In FIG. 1, reference numeral 4 denotes a window glass, which shows the state where the window glass 4 rises to the top and is fixed to the chassis frame 2, and reference numerals 4a and 3a denote the window glass 4 and the window regulator. (3) shows the state is lowered to the bottom.

Reference numeral 5 denotes a motor of the window regulator 3, which is installed in the window regulator 3, and the motor 5 is a general motor and a safety motor according to the type of the motor. Separated by.

The present invention described below is related to the safety motor described above, which will be described in detail.

When the object is detected within a predetermined section during the window glass 4 ascending, the window glass 4 is lowered to ensure safety. The safety motor 5 includes a controller (not shown) that detects an object jam in addition to the motor performance. It is supposed to work together.

In addition, the controller is very closely related to the amount of load with the peripheral chassis frame 2 generated when the window glass 4 is raised.

However, the current field problem is a type of failure in which the window glass 4 is reversed while contacting the glass run at the top as shown in FIG. 2A, and the window glass 4 as shown in FIG. It can be classified as a failure type that is reversed at the midpoint during the climb.

The former problem may be regarded as a problem due to the lifting trajectory layout of the upper end of the door and / or a dispersion (quality), and in the latter case, the controller problem of the motor 5 is dominant.

In addition, the structure of the window regulator 3 of the X-arm type is heavily loaded in the direction of the arrow between the run channel 11 and the window glass 4, as shown in FIG. 3A.

In other words, as shown in FIG. 3B, the lifting trajectory of the window regulator 3 relative to the curvature of the chassis frame 2 and the window glass 4 is subjected to a large load by the linear movement.

In order to absorb this load, as shown in FIGS. 3B and 3C, a slider 13 is provided inside the guide rail 12 of the window regulator 3, and the slider 13 and the regulator arm 14 are provided. Slider pin 15 is provided to interlock and connect, so as to absorb the amount of tension (tension) and compression (compression) when the window glass (4) ascending and descending with a constant angle (angle).

However, since the above-mentioned tension amount and compression amount are not constant for each vehicle type and differ for each layout condition, the present slider 13 and slider pin 15 are common in the vehicle having a large load, and the slider pin 15 is designed. It is difficult to absorb the load at the rotation angle of the slider pin 15 in a vehicle having a large load because the composition is useful.

4 is a problem of a vehicle with a large amount of upper compression, the distribution of the window glass 4 is severe in the direction of the arrow of the cross section, the window glass 4 hits the run channel 11 and the safety is reversed. It is a phenomenon.

Specifically, when the amount of upper compression is large, the load in the direction of the arrow in Fig. 4 takes a lot, and thus the microcomputer of the controller recognizes it as a foreign material and thus increases the possibility of inverting the window glass 4, in particular, the upper portion. In the direction of the arrow in the direction of the window glass 4 receives a lot of load when entering the upper end of the insensitivity to the run channel 11 before entering into the safety area, the microcomputer recognizes the safety area to invert the window glass 4 occurs .

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has an object of providing a structure of a window regulator of a door for a vehicle capable of stable safety control and absorbing a load by maximizing a guide rail rotation angle. .
