Window automatic closing device when the vehicle's ignition key off

The present invention relates to a window automatic closing device when the vehicle's ignition key off, and more particularly, when the ignition key is turned off while the vehicle's window is open, the ignition key of the vehicle is automatically closed. It relates to a window automatic closing device when off.

Typically, the driver's seat and the passenger seat and the passenger seat of the vehicle is provided with a glass window, the window opening and closing method according to the conventional example is to rotate the window opening and closing lever to the interior side of the door trim when the glass window is coupled to the upper side As the folding window opening and closing mechanism is expanded, a manual method of opening and closing a window is known.

According to such a manual window opening and closing, the passenger including the driver must open and close the window by rotating the window opening and closing lever by an appropriate amount, which makes the opening and closing of the window uncomfortable.

In view of such a point, in recent years, an automatic power window opening / closing mechanism that adopts an electric motor for each window and automatically opens and closes the window by operating a window opening / closing button has been applied to practical use.

However, in the case of a vehicle to which the automatic window opening / closing method is applied, when the ignition key is drawn out in a state in which the window is opened, the power applied to the window is cut off and the window is in an inoperative state. When the vehicle is stopped or parked, the risk of theft is not only generated, but foreign matter such as dust is introduced into the vehicle through the open window, especially during rain or snow, rain or snow can be found inside the vehicle. Inflowing to the interior of the vehicle, adversely affect the seat (Seat) or the like.

The present invention has been made in view of the above circumstances, and the vehicle is configured to automatically close the opened window when the open state of the window is detected even when the power supply to the window is turned off because the ignition key of the vehicle is turned off. The purpose of the present invention is to provide a window automatic closing device at the start key off.

(I.e., shown in solid lines in the drawing).

Next, a description will be given of the operation of the automatic window closing device when the start key of the vehicle according to the invention configured as described above.

First, when opening of any one window is operated by a window opening / closing button (not shown) provided inside the vehicle, the control unit 30 controls the control signals A1; B1; C1 or the window to be opened. D1) will be output. Herein, a window driven by the electric motor 61 is described as the window to be opened. For example, the control unit 30 outputs a control signal A1 for opening the window and the control signal A1 causes the window to be opened. The electromagnet 42a constituted by the first relay switch 42 of the first relay switch unit 40 is activated. Therefore, since the switching element 42b is switched connected to the contact side connected to the battery power source B + at all times, the battery power source B + is connected to the switching element 42b of the first relay switch 42 and the electric motor 61. And a grounding potential through the switching element 52b of the first relay switch 52 of the second relay switch unit 50, and thus, the window to be opened by the rotation of the electric motor 61. Will be opened.

On the other hand, when the control signal A2 is output from the controller 30 to close the open window, the first relay switch 52 of the second relay switch unit 50 is controlled by the control signal A2. ), The electromagnet 52a configured to be activated, and thus the switching element 52b is switched connected to the contact side connected to the battery power source B + at all times, so that the battery power source B + is connected to the second relay switch unit 50. Grounding through the switching element (52b) of the first relay switch 52 and the electric motor 61 and the switching element (42b) configured in the first relay switch 42 of the first relay switch unit 40 included in the As the electric potential flows, the electric motor 61 rotates in the opposite direction to the opening time, thereby closing the window of the closing object.

Therefore, by the switching action of the first and second relay switch unit 40, 50 by the control signal (B1, C1, D1; B2, C2, D2) for opening and closing the window applied from the control unit 30 The electric motors 62, 63, and 64 rotate forward / backward to perform opening and closing of the window.

Next, a process of automatically closing in accordance with the present invention when the vehicle is turned off with the window open is described.

First, when the opening and closing process of the window is performed in the start-up state of the start switch 12, the charging unit 14 is kept in a state of being charged with a constant power supply and the action of the timer reset unit 28 is performed. This causes the timer 22 to continuously reset the clocking operation.

In this state, for example, assuming that the start is turned off while the window opened and closed by the electric motor 61 is opened, the start switch 12 is changed to the disconnected state according to the start-off of the vehicle. In addition, the open state of the window is detected from the closed door limit switch 32 and applied to the controller 30.

In this case, the reset signal applied from the timer reset unit 20 to the timer 22 is blocked, and the power charged in the charging unit 14 passes through the Schmitt trigger 18 to form a waveform to perform the timer. It is applied as a trigger signal to 22 to execute the time-keeping operation for a predetermined time.

When the timer 22 has a timed operation, the timer 22 is time-determined elements 24 and 26 that are connected to the circuit by the battery power source B + applied by being decompressed by the voltage reducing unit 20. Generates a pulse signal of a time constant and applies it to the control unit 30. Accordingly, the control unit 30 supplies the control signal A2 for closing the open window to the second relay switching unit 50. Is applied to the electromagnet 52a of the first relay switch 52.

Accordingly, the electromagnet 52a of the first relay switch 52 is activated to switch the switching element 52b to the battery power source B + side, whereby the battery power source B + is connected to the second relay. Switching elements (52b) of the first relay switch 52 included in the switch unit 50 and the electric motor 61 and the first relay switch 42 of the first relay switch (40) ( 42b), and the electric motor 61 is closed so that the open window is closed under the control of the controller 30 until a closed state is detected by the closed limit switch 32. As it rotates, automatic closing of open windows is done.

Accordingly, the controller 30 automatically performs the closed problem word for the window in which the closed state limit is not detected by the closed door limit switches 34, 36, and 38 by the above process.

As described above, according to the window automatic closing device at the start key off of the vehicle according to the present invention, when the vehicle is turned off, the door is opened until the closing state is detected by the closing limit switch over a time set by the timer. Since the closed window is automatically closed, it is possible to prevent the risk of theft accident by closing the window at the start-up and to prevent the inflow of foreign substances such as dust or rainwater into the car through the open window.
