The present invention relates to a power window lifting speed control device for a vehicle, and more particularly to a power window lifting speed control device that can properly adjust the window rising and falling speed as needed.

Power window-mounted vehicles installed for the convenience of the driver use one DC forward and reverse motor for one door.

Such a power window can be controlled from the driver's seat or a switch can be installed in each door.

The electrical schematics for controlling these power windows are generally common, or vary slightly from manufacturer to manufacturer, but neither can control the lift rate of the windows.

Therefore, if you need to close the window in a hurry while the window is open, the lift speed of the window does not close immediately at the driver's discretion. For example, the interior of the vehicle is contaminated when passing through a dusty or odorous area. There is a problem.

The present invention has been made to solve the problems of the prior art, the object of the present invention is to provide a lifting speed control device that can adjust the speed of the power window to increase or slow.

In order to achieve the above object of the present invention, a casing fixedly installed in a vehicle interior, a switch knob hinged to the casing, and a contact lever each having contact protrusions at both ends thereof, and a spring supported on the casing. And a second thyristor control contact which is elastically moved in accordance with the rotation operation of the contact lever, and a second terminal of the die thruster control contact electrically connected to the die thruster control contact and the rotation of the contact lever, and formed inside the casing. The contact protrusion is formed to include the contact grooves are conducted and two of the contact grooves are connected to the low voltage motor drive terminal and the other contact grooves are connected to the high voltage motor drive terminal is optional with any one of these terminals It provides a vehicle power window lifting speed control device that can be conducted.

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

1 is a view showing a power window opening and closing system according to the present invention, a vehicle battery (2), a switch assembly (4) connected to the battery, a motor (6) providing a lifting force of the door and the on 4 thyristors SCR1, SCR2, SCR3, and SCR4 which have two modes of OFF and rotate the motor 6 in the forward and reverse directions by allowing current to flow in the forward and reverse directions.

Between the battery 2 and the switch assembly 4, a high voltage input line 8 for flowing the voltage of the battery as it is, and a low voltage input line 12 for applying a low voltage through the resistor 10 are connected. have.

This structure is connected to a circuit which allows the motor 6 to drive in the forward rotation direction when the thyristors SCR1 and another thyristors SCR4 are turned on.

2 is a side cross-sectional view of the switch assembly 4 according to the present invention, which is provided with a casing 14 installed inside a vehicle body such as a panel of a door, and installed in the casing so as to be rotatable in the front and rear or left and right directions. And a switch knob 16.

The switch knob 16 is hinged to the casing 14 with a pin 18, and the contact lever 22 is hinged to the casing 14 by another pin 20 to the lower side thereof. The switch knob 16 can be interlocked according to the switching operation.

Contact protrusions 24 and 26 are installed at both ends of the contact lever 22, and the contact protrusions are respectively located in the contact grooves 28, 30, 32, 34 formed on the inner surface of the casing 14. Only when artificial force is applied is it possible to leave the position.

The contact lever 22 is supported by a spring 36 so as to maintain an equilibrium at all times around the pin 20 installed at the hinge point, and the switch knob 16 is connected to the contact lever by the pushing protrusion 38. It is in contact with.

The casing 14 is provided with a first thyristor control contact first terminal 40, 40 'and a second terminal 42, 42'. The first terminal 40 has a casing 14 The thyristor control contact 46, which is located inward and is supported by the spring 44, can be electrically connected to the second terminal 42 side.

Although the switch knob 16 is separated from the second terminal 42 at the neutral position, the die thruster control contact first terminal 40 has a spring (for example, when the right end is pressed). The control contact 46 is electrically connected to the second terminal 42 while the control contact 46 moves downward by the elastic force of 44.

The casing 14 is provided with low voltage motor drive terminals 48 and 48 'and high voltage motor drive terminals 50 and 50'.

The second terminal 42 is electrically connected to the high voltage motor driving terminals 50 and 50 '. When one end of the switch knob 16 is called the window lower side knob, the opposite side is raised. Side knob.

3 is an electric circuit diagram showing a switching means according to the present invention, wherein one side of the knob 16 is the window lowering operation part 16a, and the other side is the window raising operation part 16b. It is designed to receive the falling signal.

Each of the lower operation unit 16a and the upward operation unit 16b is a switch having the same structure, and when the knob 16 is pressed, a lower signal or a higher signal is provided in two thyristor control contacts 46 and 46 according to the pushing direction. It can be connected to any one of the control contacts. When the switch knob 16 is pressed further, any one of the contact protrusions 24 and 24 'is positioned as one of the contact grooves 28 and 28', and in this state, the switch knob is pressed further. If one of the contact grooves (30, 30 ') is located.

Reference numeral 52 in the figure is a motor applied power supply line.

In the window elevation control device of the present invention, which is configured as described above, when the switch knob 16 is pressed, any one of the thyristor control contacts 46 and 4 'is connected to the second terminal 42 and 42' side. do.

As an example, when the window is lowered, the right end of the switch knob 16 is pressed in FIG. 2, and the die thruster control contact 46 is in electrical contact with the second terminal 42.

By this action, the control contact first terminal 40 and the second terminal 42 are electrically connected to each other. In this state, the power supply of the battery 2 is turned on by the thyristor SCR1 and another thyristor SCR4. Since it is applied toward the side, the motor 6 has a circuit connection in a state capable of rotating in the forward direction.

In this state, when the switch knob 16 is pressed once, the contact protrusion 24 of the contact lever 22 is electrically connected to the contact groove 28, and this state can be understood through FIG. 3. As shown, since the low voltage input line 12 is connected to the motor drive output, the motor 6 performs the low speed forward rotation.

When the motor is subjected to a low speed forward rotation, the window associated with the motor 6 opens at the normal speed while opening the window.

When the switch knob 16 is further pressed in the above-described state, the contact protrusion 24 of the contact lever 22 is positioned in the contact groove 30 to be electrically energized. In this case, FIG. Since the high voltage input line 8 is connected to the motor drive output side, the motor 6 rotates forward at a high speed.

Therefore, the window related to the motor 6 is opened faster than when the switch knob is set to 1 stage. On the contrary, when the left end of the switch knob 16 is called, the window is increased at a normal speed or at a high speed.

As described above, the power window lift speed control device according to the present invention is capable of controlling the lift speed of the window by allowing the switch knob to be operated in one or two stages as necessary, so that the driving state or the surrounding situation can be controlled. In accordance with this, the window can be opened or closed as appropriate, thereby eliminating the problem of the conventional power window opening and closing apparatus.
