Abstract

The present invention relates to a window closing device of a vehicle that can prevent the risk of theft due to the opening of the window by configuring a logic circuit that automatically closes the window when the driver locks the door of the vehicle during parking. The key-off input terminal 11 for inputting the off state and the key-off input terminal 12 for inputting the subtracted state are connected to output the driving signal only when the two input terminals 11 and 12 simultaneously form the off state. A first gate and a not gate 30 outputting a driving signal when the window is open, and a signal and sickle output and input from the first end gate 10. The signal output from the gate (Not Gate) 30 is the second end gate (And Gate) 20 to output the drive signal of the window only when the drive signal is output at the same time.

Description

Window closure device of vehicle

The present invention relates to a window closing device of a vehicle, and in detail, by configuring a logic circuit that automatically closes a window when the driver locks the door of the vehicle during parking, the risk of theft due to the opening of the window can be prevented. To a window closure device of a vehicle.

In general, when the driver turns off the vehicle, the driver pulls the key to park the vehicle and finally locks the door to park the vehicle.

However, when the driver closes the door without inadvertently closing the window when the driver closes the door, there is a risk of theft of the front part of the vehicle.

In addition, even if the driver recognizes this, the window of the door should be closed by the driver.

The present invention has been made in view of the above problems, and an object of the present invention is to configure a logic circuit that automatically closes a window when the driver locks the door of the vehicle during parking, thereby reducing the risk of theft by opening the window. An object of the present invention is to provide a window closing device for a vehicle that can be prevented.

1 is a circuit diagram showing a window closing apparatus of a vehicle according to the present invention

* Description of the symbols for the main parts of the drawings *

10: first end gate (And Gate) 11: start-off input terminal

12: key off input stage 20: second end gate (And Gate)

30: Not gate 31: window switch input stage

In order to achieve the above object, according to the present invention, a key-off input terminal for inputting a start-off state and a key-off input terminal for inputting a subtracted key are connected so that two input terminals simultaneously form an off state to output a driving signal. 1 And gate, Not gate for outputting a drive signal when the window is open, the signal output from the first end gate and the output is input from the not gate (Not Gate) The basic feature is that the input terminal is composed of a second end gate (And Gate) for outputting the driving signal of the window only when the driving signal is output at the same time.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a logic circuit diagram showing a window closing apparatus for a vehicle according to the present invention, showing the logical configuration of the present invention.

A start-off input terminal 11 for detecting that the start is turned off is formed, and a key-off input terminal 12 for detecting a state in which the driver pulls out the key is connected to the first end gate 10.

That is, the two input terminals 11 and 12 as described above indicate a state in which the vehicle is parked, and the window switch input terminal 31 indicating the open state of the window is the not gate 30 at the window side. When the door is off, the drive signal is output.

On the other hand, the output signal of the first end gate (And Gate) 10 and the not gate (Not Gate) 30 is applied to the two input terminals (21, 22) of the window only when the driving signal is input A second end gate (And Gate) 20 for outputting a closing drive signal is connected.

This state indicates the driver's careless state by recognizing only when the vehicle is parked and when the window of the door is not closed, and only in this state, the second end gate 20 outputs the closed driving signal of the window. Will automatically close.

The above shows the logical circuit configuration of the present invention. The circuit device for constructing the logic device may be formed in various forms.

Therefore, the present invention has the operation of closing the window automatically by recognizing the case in which the vehicle is parked and the case in which the driver has not been inadvertently closed by the logical circuit configuration for operating the window as described above, and thus, various electric appliances in the room You can prevent theft of things.

In addition, even if the driver recognizes and closes the open state of the window, the inconvenience of having to directly operate the window is to automatically close the window, thereby providing a factor that can increase the merchandise of the vehicle.

As described above, the present invention is a useful invention that can prevent the risk of theft due to the opening of the window by configuring a logic circuit to automatically close the window when the driver locks the door of the vehicle during parking.

Claims (1)

The first end gate (And Gate) and the window to output the drive signal only when the key-off input terminal for inputting the start-off state and the key-off input terminal for inputting the subtracted key are connected to form an off state at the same time When the gate is open, the not gate for outputting the driving signal, the signal output from the first end gate and the signal output from the not gate are input simultaneously to output the driving signal. The window closing device of the vehicle, characterized in that consisting of a second end gate (And Gate) for outputting a drive signal.
