Description

Door glass anti-flow device of car {APPARATUS FOR FLOATING A DOOR GLASS OF AN AUTOMOBILE}

The present invention relates to a door glass flow preventing device of an automobile.

In general, in the case of a passenger car, the body of a vehicle is usually formed by attaching a door, a trunk lid, a hood, etc. to an integrated frame, and a door is provided with a lifting device for lifting the door glass.

As such a lifting device, a manual type which raises and lowers the window glass by rotating a handle, and an electric type which is lifted by a motor are used. This situation is widely applied and spread.

On the other hand, when lifting the door glass through the lifting device in this way, it is necessary to guide the slide glass so that it can be slidably conveyed without flow.

To this end, as shown in FIG. 3, a door channel 20 is fixedly installed inside the door panel 10, and the door channel 20 is coupled to both side surfaces of the lower portion of the door glass D. Carrier 30 is slidably installed up and down.

In addition, a regulator 40 is provided to lift and lift the door glass D by transporting the carrier 30.

On the other hand, on the door panel 10, that is, the door inner panel 11 and the door outer panel 12 to support the flow without the door glass (D) is lifted, the inner belt 13 and the outer belt ( 14) are provided respectively.

Although not shown, a glass run is provided to support both sides of the door glass D.

In the conventional door, the carrier 30 moves up and down along the door channel 20 according to the operation of the regulator 40, and at the same time, the door glass D to which the carrier 30 is coupled is lifted.

At this time, in the lifting process of the door glass (D) is to support the door glass (D) to be lifted and lifted through the inside belt 13, the outside belt 14 and the glass run without flow.

However, in such a conventional door, after a certain time has elapsed, the door glass D is severely flown when the door panel D is opened and closed while the door glass D is lowered, or during the driving process. Problems that occur are caused.

This problem is caused by wear and tear of the inside belt 13 and the outside belt 14 and the glass run that are in contact with it as the door glass D is repeatedly raised and lowered. This is because such factors cause a gap between the door glass D and the hardening and oxidation of the molded article.

In addition, in the state in which the door glass D is lowered, particularly, the flow is generated in a state in which the glass glass and the inner belt 13 and the outer belt 14 are in uniform contact with each other in the state in which the door glass D is raised. However, in the lowered state, only the glass run is supported by the glass run, which causes more serious flow when the glass run wears out.

On the other hand, when the flow of the door glass (D) in this way, not only does not damage the door glass (D), but also generates a lot of noise, stable lifting and lifting of the door glass (D) is not made and the regulator 40 and Damage to the carrier 30 is caused.

The present invention was created in order to solve such a conventional problem, even if a gap occurs between the door glass and the wear or hardening and oxidation of the rubber belt or glass that supports the door glass occurs It is an object of the present invention to provide a door glass flow preventing device of a vehicle that can prevent the occurrence of flow at the time of opening and closing of the vehicle and to maintain a quiet running environment.

In order to achieve the above object, the present invention includes a carrier sliding along the channel through a regulator located on the inner surface of the door panel; A door glass fixedly installed at the carrier and conveyed up and down, and having both sides supported by the door glass;

D: Door Glass

As shown in FIG. 1 and FIG. 2, in the present invention, a channel 20 is fixedly installed inside a door panel 10, that is, between the door inner panel 11 and the door outer panel 12. Carrier 30 is installed in the channel 20 so as to slide up and down through a regulator 40.

At this time, the carrier 30 is fixed to both sides of the lower side of the door glass (D) to be transported through the regulator 40 to perform the function of lifting the door glass (D).

Meanwhile, the front and rear surfaces of the door glass D, which are lifted and lifted through the carrier 30, are supported by the inside belt 13 and the outside belt 14 provided on the door panel 10, and both sides of the glass (Not shown) is supported.

In addition, after a certain time elapses, wear occurs in the inside belt 13, the outside belt 14, and the glass run to compensate for the flow generated by the gap generated between the door glass D. That is, the pressurizing means 100 is provided to pressurize and support the door glass D so that no flow is generated.

The pressurizing means 100 has substantially the characteristic elements of the present invention, and the detailed structure of the pressing means 100 is provided on the outer rail 15 provided to reinforce rigidity inside the door outer panel 12. The bracket 110 is fixedly installed through the bolt B and the nut N.

The bracket 110 is rotatably hinged to the center plane of the rotating arm 120, which is composed of a horizontal arm 121 and a vertical arm 122.

The horizontal arms 121 extend in parallel with each other in the horizontal direction with respect to the hinge coupling portion, and the through holes 121a are formed in corresponding surfaces thereof.

The vertical arm 122 extends vertically downward with respect to the hinge coupling portion, and in particular, the fixing pin 123 is integrally formed in the horizontal direction on the inner front surface.

At this time, the hinge arm of the rotary arm 120 is interposed with a torsion spring 124 elastically supporting the rotary arm 120 in a direction opposite to the door glass (D).

And to prevent the horizontal arm 121 from contacting the outer rail 15 when the rotary arm 120 is rotated by the torsion spring 124, that is, the rotation range of the horizontal arm 121 A stopper 15a is formed to protrude in order to restrict.

On the horizontal arm 121 of the above-described rotating arm 120, a cylindrical roller 130, which is selectively in contact with the surface of the door glass D, rotates through the hinge pin 131 penetrating the through hole 121a. Possibly combined.

The cylindrical roller 130 should be firmly coupled to the hinge pin 131, and should be gently in close contact with the door glass D so as not to damage the surface when the door glass D is elevated.

To this end, the inner and outer surfaces of the cylindrical roller 130 need to be different from each other.

That is, the inner surface should be molded of a hard material and the outer surface should be molded of a soft material.

As one example, the cylindrical roller 130 may be formed by forming a cylindrical shape with metal and molding a rubber through inserting on the outer circumferential surface thereof.

A pulley 140 is also rotatably coupled to the fixing pin 123 integrally provided on the inner surface of the vertical arm 122 of the rotating arm 120.

The wire 141 is wound around the outer circumferential surface of the pulley 140 a predetermined number of times, and the end of the wire 141 is drawn out vertically downward.

The fixing pin 123 rotatably hinged to the pulley 140 to impart an elastic force in one direction to the pulley 140, that is, to impart an elastic force in a direction opposite to the unwinding direction of the wire 141. One-way spring 142 is interposed.

In this case, a guide hole (not shown) is formed at the end of the vertical arm 122 of the rotation arm 120 described above so that the wire 141 vertically drawn from the outer circumferential surface of the pulley 140 can be stably guided without interfering with other components. It will be desirable to extend the horizontally formed flange (125) (125a) is formed through.

On the other hand, the lower portion of the door panel 10, that is, the outer surface of the carrier 30 coupled to the door glass (D) is fixed to the plate (plate; 150) having a hook 151 is formed on one side upper surface.

This plate 150 is in particular bolted together to a bolt B which secures the carrier 30 and the door glass D together.

The lower end of the tension spring 160 is fixed to the hook 151 of the plate 150, and the upper end of the tension spring 160 is coupled with the wire 141 drawn from the pulley 140.

Reference numeral R is a ring interposed at the end of the fixing pin 123 to prevent the pulley 140 from being separated.

According to the present invention configured as described above, the glass run or the inner belt 13 and the outer belt 14 are moved when the door glass D is lifted through the carrier 30 slidingly moved along the channel 20 through the regulator 40. Even when abrasion occurs, the door panel 10 is not flown in the process of opening and closing the door panel 10, and flow is prevented even during driving, thereby achieving a quiet driving environment.

In more detail, when the door glass D is raised and lowered by operating the regulator 40 to open it in the elevated state, the door glass D is lowered together with the carrier 30 and at the same time the outside of the carrier 30. Plate 150 provided on the side is lowered together.

As the plate 150 descends together with the carrier 30, the tension spring 160 having the lower end coupled to the hook 151 of the plate 150 pushes the wire 141, and the pulley 140 rotates. A certain amount of wire 141 is drawn out below.

At this time, by rotating the pulley 140, the one-way spring 142 interposed in the fixing pin 123 rotatably coupled to the pulley 140 stores the elastic force as much as the rotation amount of the pulley 140. .

That is, the pulley 140 has a force to rotate in a direction opposite to the unwinding direction of the wire 141.

In this state, when the door glass D, the carrier 30, and the plate 150 descend to some extent, the withdrawal of the wire 141 is stopped, but the tension spring 160 continues to move the wire 141 downward. Pushed.

Accordingly, the push force in the downward direction is applied to the rotary arm 120, the rotary arm 120 is rotated while overcoming the force of the torsion spring 124, the door glass (D) that the horizontal arm 121 is lowered Is rotated to.

Accordingly, the surface of the cylindrical roller 130 rotatably coupled to the horizontal arm 121 is pushed outward while being in contact with the surface of the door glass D, thereby stably lowering the door glass D without flowing. .

At this time, in a state where the door glass D is completely lowered, the cylindrical roller 130 on the horizontal arm 121 is pressed against the surface of the door glass D by a very large force, thereby opening the door glass D. Noise caused by the flow is not generated even when driving in or when opening or closing the door.

That is, it is possible to maintain a quiet driving environment.

When the door glass D is raised in this state, the push force in the downward direction of the wire 141 through the tension spring 160 is gradually released, and accordingly, the pulley (ie, the elastic force stored in the one-way spring 142) is released. As the 140 is rotated in the winding direction of the wire 141, the wire 141 is wound around the outer circumferential surface.

At this time, as the wire 141 is wound, the rotating arm 120 rotates in a direction opposite to the door glass D through the elastic force of the torsion spring 124, and accordingly, the cylindrical roller coupled to the horizontal arm 121 ( 130 is gradually separated from the surface of the door glass D so that it does not affect the ascent.

Therefore, the door glass D is stably raised while being supported by the inside belt 13 and the outside belt 14.

As described above, according to the present invention, when the door glass is lowered, it is pressurized and supported by the pressing means, so that no flow occurs even if a gap is generated between the belts and the glass run by abrasion or hardening.

Therefore, the noise caused by the flow is not generated even when the vehicle is driven while the door glass is opened, and the flow is not generated even when the door is opened or closed.

In addition, damage to the door glass due to flow can be prevented in advance, and the life of other regulators and carriers can be extended.

As a result, it is possible to meet the consumer's satisfaction with the car employing it, thereby improving the reliability.
