Description

Power window regulator device for working together air bag device

The present invention relates to an airbag interlocking power window regulator device, and more particularly, to an airbag device interlocking power window regulator device that can prevent injuries of the occupants due to an increase in pressure in a car interior that occurs when an airbag of the car is exploded. It is about.

In general, the US Highway Safety Administration (NHTSA) is required to check the safety of the driver and occupant in the vehicle's interior when a collision occurs due to a driver's mistake or other external factors while driving. Collisions, side collisions and offset collisions are being tested.

Therefore, in order to reduce the impact of a driver and a passenger at the time of a collision, the airbag system is installed in the predetermined position of the vehicle interior.

When such an airbag system is operated, two major problems occur.

First, there is an increase in the pressure inside the car, which is very likely to cause gas emissions from the inflator during operation of the airbag, resulting in a sudden increase in the car interior pressure when the airbag is deployed, which impairs the driver's hearing function.

In order to solve this problem, Korean Utility Model Publication No. 2000-0011938 installs a low pressure tank at a predetermined position of a vehicle body to open the low pressure tank during operation of an airbag to prevent an increase in pressure in the interior of a vehicle, and to provide a domestic utility model publication number. No. 1999-0031801 installs a rear deck trim speaker separately to remove the airbag during operation to reduce room pressure.

Second, if the door does not open or the central door lock system is in a state where the car is bitten due to the collision of the car, the door is kept locked and the door is not opened from the outside, which is very inconvenient for the passenger's quick rescue activities. Will be given.

On the contrary, Korean Patent Publication No. 2000-0020116 allows the door to be opened by moving a separate piston rod fastened to the inside handle rod, and Korean Patent Publication No. 2000-0033682 discloses an engine when the airbag is operated. The system is using a method to stop the operation and automatically open the door in the central door lock system.

The above methods, which are proposed to solve the problems that occur during the operation of the airbag system, are only a solution to one of the problems of reducing the pressure inside the vehicle or opening the door. Both goals are not met.

Alternatively, Korean Patent Publication No. 1998-0052282 discloses that when an operation signal is sent from an airbag diagnosis unit (SDU) for deploying an airbag, the operation signal activates the airbag and electronic control for power window operation. It is input to the device ECU and the window glass is lowered by rotating the power window motor by a conventional method.

As such, when the window glass is lowered, the pressure in the vehicle interior is reduced, and it is easy to rescue the passenger.

However, the Korean Patent Publication No. 1998-0052282 includes some problems.

After the control signal is sent to the ECU, the power window is driven by the power supply unit.

(1) Damage to the electronic control unit (ECU)

(2) damage to the power window motor

(3) damage to the power supply

(4) If a short circuit or the like connecting the motor and the power supply occurs, the system will not work and the original purpose cannot be achieved.

On the other hand, Korean Patent Publication No. 2002-0040364 has a damage device inside the door, and breaks the window glass during a collision, thereby solving the pressure reduction in the interior of the vehicle and ensuring the ease of passenger structure.

In addition, the method proposed in Korean Patent Laid-Open Publication No. 1998-0052282 includes the uncertainty of the system operation because the power window lowering speed by the motor is not fast even if the system is operated properly, but the Korean Patent Publication No. 2002-0040364 The glass breakage method of the arc is a more advanced method in that the operation speed is high and the system reliability is high.

However, the Korean Patent Publication No. 2002-0040364 also has a big problem.

That is, since most of the window glass is made of tempered glass, it is hard to be broken and when the glass is broken, the entire glass is broken into small pieces, and Korean Patent Publication No. 2002-0040364, which is designed to always break the window, shows that Deadly secondary damage to the human body may occur due to window glass broken pieces, and there is a problem that the occupant rescue operation is also difficult to proceed smoothly.

In addition, even if the damage of the door is a minor collision, the maintenance work is inconvenient, and the parts are not recycled because it must be replaced with a new window after the system operation.

Accordingly, the present invention has been made to solve the above problems, to provide a power window regulator device that can open the window glass to prevent the injury of the occupants due to the increase in the room pressure of the car when the airbag operation. The position of the motor mounted to wind the cable in the regulator device is moved to the slide side by the collision signal to remove the tension action state of the cable, which is kept tight, so that the window glass can be lowered without being damaged by its own load. Thus, when the airbag is operated in an enclosed room, the indoor air as much as the pressure of the inflated airbag can be instantaneously and smoothly released to the outside of the vehicle, thereby reducing the pressure in the vehicle interior and of It not only satisfies the ease of securing Am, to provide a secondary damage which can prevent air bag device linked power window regulator device due to the window glass breakage it is an object.

Hereinafter, the features of the present invention for achieving the above object are as follows.

The present invention provides a power window regulator apparatus for an automobile installed inside the door panel so that the window glass mounted on the carrier plate can be raised and lowered by driving a motor.

When the vehicle crashes, the airbag device linked drive means 10 which is operated by the airbag device's deployment signal through the control signal of the airbag diagnosis unit (SDU) 20 to automatically lower the window glass 100. It is characterized by including.

The present invention relates to an airbag device-linked power window regulator device capable of simultaneously reducing the vehicle interior pressure and ensuring the ease of occupant rescue activities while operating the airbag of the vehicle and at the same time preventing secondary damage due to window glass breakage. will be.

As shown in FIG. 1, in the power window regulator device, a slide 110 for guiding the up and down movement of the window glass 100 is provided inside the door panel by a regulator holder (not shown).

In addition, the cables 120 for moving the window glass 100 up and down are connected to the rollers 130 at the upper and lower sides, respectively, and extend, and are wound on the drive shaft of the motor 150 mounted on the motor plate 140. It is rotatable.

On the other hand, the window glass 100 is fixed on the carrier plate 160 sliding in the vertical direction in the slide 110.

In this case, since the window glass 100 is slightly convex, the slide 110 is moved close to the circular arc motion, which is curved when the motion has a rather large radius of curvature rather than a perfect linear motion. It is installed slightly curved to have a radius of curvature similar to the radius of curvature.

The configuration of such a power window regulator device of an automobile is the same as the conventional general technical configuration, and the configuration described below is related to the preferred configuration of the present invention.

In a preferred embodiment according to the present invention for achieving the above object, the airbag device interlocking operation means 10 to guide the position movement of the motor plate 140 to the upper and lower ends of the motor plate 140. The guide 11 is provided, and the diaphragm 12 which is supported by the side to which the motor 150 moves and restricts the movement of the motor 150 is provided, The upper end of the diaphragm 12 has an airbag apparatus. The pressure cylinder 13 which operates a piston by the control signal of the airbag diagnostic unit (SDU) 20 which received the deployment signal of is provided.

Hereinafter, the operation principle of the conventional power window regulator device prior to the operation principle of the airbag device-linked power window regulator device configured as described above, first, the cable 120 wound on the motor 150 is It is to be rotated through the slide 110 and the roller 130 in one piece without a cut part, and is fixed to the carrier plate 160, when the cable 120 is rotated by the motor 150, the carrier accordingly The plate 160 and the window glass 100 fastened to the carrier plate 160 are driven up and down together to open and close the power window.

As a feature of the present invention, it is possible to automatically operate the power window regulator device according to such an operation so as to prevent injuries of the occupants due to an increase in the indoor pressure of the vehicle generated when the airbag is exploded. The principle of operation for achieving the purpose of the present invention will be described.

When the collision of the vehicle occurs and the airbag driving control signal and the power window driving control signal are generated by the airbag diagnosis unit 20 that has received the collision signal, the airbag module of the airbag apparatus is operated and the airbag diagnosis unit 20 ) Signal is transmitted directly to the pressure cylinder 13 installed inside the door panel without passing through the electronic control unit (ECU), which explodes the gas in the pressure cylinder 13 in the same manner as gas discharge from the airbag inflator. The pressure causes the piston to push away the diaphragm 12 holding the motor plate 140 (see FIG. 2A).

In this case, since the diaphragm 12 of the side of the motor plate 140 is removed, it is moved to the carrier plate 160 along the guide 11 by the elastic force of the cable 120 (see FIG. 2B).

At the same time, the cable 120 in the state of being kept tight and connected to the window glass 100 is loosened, so that the window glass 100 and the carrier plate 160 are not damaged by their own loads, but are immediately lower than the door panel. It will descend to (see Fig. 2c).

As described above, in the present invention, when the window glass 100 is not damaged and only the diaphragm 12 dropped to the bottom is remounted, the power window device is normally operated, which is advantageous in terms of ease of repair work and part recycling.

In addition, it is possible to achieve all of the objectives of the present invention, namely, reducing the vehicle interior pressure, ensuring the occupant's structure, preventing secondary injury due to glass breakage, and even if the door of the vehicle is damaged during the second collision. Since the glass 100 is already lowered into the door panel, the broken window glass 100 remains inside the door panel so that secondary injury does not occur.

As described above, according to the airbag device-linked power window regulator device according to the present invention, the following effects are obtained.

1) When the airbag is in operation, the pressure inside the room can be effectively reduced, thus preventing injuries of the occupants, that is, hearing impairment.

2) If the door does not open due to car collision and the door does not open, or the door is kept locked, the door does not open from the outside. As it is open, the ease and speed of occupant rescue activities are ensured.

3) Since the control signal does not go through the electronic control unit (ECU), motor, etc., the operation path is simple, so the response time after the collision is short.

4) There is no damage to the window glass, and only the separated components need to be refitted, making maintenance work easier and recycling parts easier than existing systems.
