Description

Window regulator of car door

The present invention relates to a window regulator of a car door, and more particularly to a window regulator of a car door having a fixing structure that can be fixed more easily and reliably to the upper guide channel.

In general, a door window regulator, which is a device for opening and closing a door window, is classified into a manual type that operates by rotating a fan-shaped gear by a handle, and an electric type that opens and closes the door glass by a DC series motor instead of the regulator handle.

The window regulator of such an automobile door is shown in FIG. 1.

As shown, the door glass 1 is slid between the upper guide channel 2 having a fixed and long hole and the lower guide channel 3 having a long hole formed and fixed at the bottom of the door. To enable movement, a pair of equalizer links (4, shaped in shape) are inserted into each of the holes and the holes so that they cross in a cross shape. The equalizer link 4 inserted into the right slot of the lower guide channel 3 is coupled to one side of the regulator arm 5 having a fan-shaped gear part 5a formed on the other side thereof. . The gear portion 5a of the regulator arm 5 meshes with the gear 6a mounted on the shaft 6 of the motor or the handle which is the driving source.

In this way, in the window regulator of the automobile door which is configured, the regulator arm 5 moves to the left or right side by turning the handle or by operating the motor to rotate the gear mounted on the shaft 6, and the equalizer link 4 ) Is also moved within the length range of the long hole 3b to the left or to the right. Accordingly, the upper guide channel 2 is moved up and down, and the door glass 1 mounted thereon also moves up and down.

Here, the fixing structure for the upper guide channel of the door glass which is moved by the window regulator will be described in more detail as follows.

As shown in detail in FIG. 2, a fastening hole 1a is formed at a lower side of the door glass 1, and the periphery of the fastening hole 1 is surrounded by a grommet 7 fitted from a lower side. In addition, a fastening hole 2a corresponding to the upper guide channel 2 is also formed, and the door glass 1 and the upper guide channel 2 have screws 8 having respective fastening holes 1a and 2a. It is fixed to each other by being fastened through. Although not shown, the opposite side of the door glass and the upper guide channel is likewise fixed.

However, in the conventional window regulator of the automobile door as described above, it is cumbersome to fix the screw to match the position of the fastening hole of the door glass and the upper guide channel when assembling the automobile door. Vibration caused the screws to loosen, causing the door glass to disconnect from the upper guide channel of the window regulator.

Accordingly, an object of the present invention is to provide a window regulator of an automobile door having a structure that can fix the glass door and the upper guide channel more easily and reliably.

The present invention for achieving the above object is provided so that the glass is fixed to the upper guide channel, the lower guide channel which is located on the lower portion of the upper guide channel and fixed to the outer panel of the door, the upper and lower guide channel A vehicle door window regulator comprising a pair of equalizer links, a regulator arm fixed to one of the pair of equalizer links, and a means for driving the regulator arm, wherein door glasses are inserted at both ends of the upper guide channel. An insertion groove is positioned between the case formed at the center of the upper surface and a pair of supports having substantially pyramidal shape points on both sides of the inside of the case and having the pointed portions facing each other, and positioned between each of the supports and the wall of the case to resilient the support to the center. Consisting of supporting springs The fixture is attached.

In the window regulator of the automobile door according to the present invention configured as described above, when both sides of the door glass are inserted into the insertion groove of the fixture, the peaks of the pair of supports that are elastically supported by the spring are inserted into the fastening holes of the door glass to contact each other. The door glass is fixed to the upper guide by being made.

EXAMPLE

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

The basic structure of the window regulator of the automobile door according to the present invention is the same as that of the conventional window regulator as shown in FIG. 1, and the structure of fixing the door glass to the upper guide channel is improved.

That is, a pair of equalizer links (4, Equalizer link) between the upper guide channel (2) to which the door glass (1) is fixed and the lower guide channel (3) installed in the lower portion of the door in a cross shape to enable the sliding movement. Installed cross. In addition, a regulator arm 5 having a fan-shaped gear portion 5a formed at the other end thereof is coupled to one side of the equalizer link 4, and the gear portion of the regulator arm 5 has a shaft 6 of a motor or handle which is a driving source. Meshes with the gear 6a mounted on it.

In addition, the fixture 10 is attached to both ends of the upper guide channel 2 to fix the door glass 1 to the upper guide channel 2. The fixture 10 is as shown in FIGS. 2 and 3. In the drawing, the reference numeral 11 is a case, the insertion groove (11a) is formed in which the one end of the door glass 1 is inserted in the center of the upper surface. Inside the case 11, a pair of supports 12 having a pyramid-shaped pointed portion are installed so that the pointed portions face each other, and a spring 13 is disposed between the support 12 and the wall surface of the case 11. Is installed to elastically support the support 12 to the center.

When the door glass 1 is inserted into the insertion groove 11a of the case 11 from above, the pair of supports 12 are pushed to both sides by the door glass, and the fastening hole 1a of the door glass 1 is pushed. When lowered to the pointed position of the support 12, the pointed portions of both support 12 are inserted into the fastening hole 1a by the elasticity of the spring 13 to contact each other. Therefore, the door glass 1 is fixed so as not to be separated from the fixture 10 by the support 12 supported by the elasticity of the spring 13.

Therefore, the door glass 1 is fixed to the upper guide channel 2, and when the motor 6 or the handle is rotated to rotate the gear 6 mounted on the shaft, the regulator arm 5 moves to the left or the right, The equalizer link 4 is also moved left or right. Therefore, the upper guide channel 2 is moved up and down, and the door glass 1 mounted thereto moves up and down.

When the window regulator of the automobile door according to the present invention as described above is fixed by the support that is supported by the spring when the door glass is inserted into the insertion groove of the fixture, the door glass is very simply and securely fixed to the upper guide channel. In addition, there is an advantage that the door glass is not separated from the upper guide channel by the vibration of the driving of the vehicle.
