Abstract

PURPOSE: A device for protecting children by a power window is provided to protect the children from the accident by making the power window not open completely when the child gets on the car without any protector. CONSTITUTION: The device for protecting children by the power window includes a window switch(11), a window motor(12), a safe mode switch(20), the highest limit switch(LST), the middle limit switch(LSM) and the lowest limit switch(LSB). The window switch(11) is connected between a contact point of "on" and grounding and opens and closes the window. The window motor(12) is connected to the window switch(11) and makes the window move up and down. The highest limit switch(LST) cuts off the current of the window motor(12) when the window approached the highest step. The safe mode switch(20) is connected to the highest limit switch(LST) and sets up or releases the safe mode. The middle limit switch(LSM) cuts off the current of the window motor(12) when the window approached the middle step. The lowest limit switch(LSB) cuts off the current of the window motor(12) when the window approached the lowest step.

Description

{Apparatus for protecting children for power window}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power window control apparatus for a vehicle, and more particularly, to a child protection apparatus for a power window for preventing a child safety accident by preventing the power window from being fully opened when a child rides without a guardian other than the driver.

Generally, as shown in FIG. 1, a vehicle power window control apparatus includes a window switch 11 connected in parallel between an “on” contact of an engine switch and ground to open and close a window; A window motor 12 connected to the window switch 11 to raise or lower the window; The upper limit switch (LST) connected between the window switch 11 and the window motor 12 to cut off the current of the window motor 12 when the window reaches the top, and the window when the window reaches the bottom It consists of the lowest limit switch LSB which interrupts the electric current of the motor 12. As shown in FIG.

In addition, as shown in Fig. 2, the uppermost limit switch LST is installed at the uppermost end where the lower end of the window can reach, and the lowermost limit switch LSB is installed at the lowest end that the lower end of the window can reach. The window force 12 is converted into a vertical motion by the window regulator 13 to raise or lower the window.

That is, when the window switch 11 is connected to the "UP" or "DOWN" side, current flows to the window motor 12 in the "UP" or "DOWN" direction to raise or lower the window. At this time, when the window reaches the top, the uppermost limit switch (LST) is turned off to block the rising current flowing through the window motor 12 to limit the window from rising more than the top. When the window reaches the bottom end, the bottom limit switch LSB is turned off to block the falling current flowing through the window motor 12 to limit the window from falling further than the bottom end.

When a child rides in a vehicle and the power window is completely open, the child may be injured by pushing a part of the body out of the vehicle.

As such, the conventional power window control device does not prevent child safety accidents that may occur when an infant or a child rides in the passenger seat or the rear seat without another guardian who is accompanied, and the driver frequently gives attention to the child while driving. There was a disturbing problem.

An object of the present invention is to solve the conventional problems, in particular, when the child rides without a guardian other than the driver to open the power window only to a predetermined position to prevent child safety accidents, power windows that can contribute to safe driving To provide child protection for children.

The child protection device of the power window of the present invention comprises: a window switch for opening and closing the window by being connected in parallel between the "on" contact (ON) of the engine switch and ground; A power window control device comprising a window motor connected to the window switch to raise or lower a window, the power window control device comprising: a top limit switch connected to the window switch to block a current of the window motor when the window is reached at the top; A safety mode switch connected to the upper limit switch to set or release a safety mode; An intermediate limit switch connected between the on-contact point of the safe mode switch and the window motor, the intermediate limit switch blocking the current of the window motor when the window reaches an intermediate predetermined position; And a lower limit switch connected between an off-contact point of the safe mode switch and the window motor, and blocking the current of the window motor when the window reaches the lower end.

An embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4 as follows.

The child protection device of the power window of the present invention includes a window switch (11) for opening and closing the window by being connected in parallel between the "on" contact (ON) of the engine switch and ground; In the power window control device comprising a window motor 12 connected to the window switch 11 to raise or lower the window, the window motor 12 is connected to the window switch 11 when the window reaches the top. A top limit switch (LST) to cut off a current of the circuit; A safety mode switch 20 connected to the uppermost limit switch LST to set or release a safety mode; An intermediate limit switch (LSM) connected between the on-contact point (ON) of the safe mode switch (20) and the window motor (12) and for interrupting the current of the window motor when the window reaches an intermediate predetermined position; The lower limit switch LSB is connected between the OFF contact of the safety mode switch 20 and the window motor 12, and cuts off the current of the window motor 12 when the window reaches the bottom end. It is composed.

When a child rides in the vehicle without any other guardian other than the driver, the driver sets the safety mode by connecting the safety mode switch 20 to the ON contact ON. In this way, when the child operates the window switch 11 to "UP" or "DOWN" in the safety mode is set, the window is raised / lowered between the predetermined position in the middle and the top end.

Accordingly, since the window does not open below the predetermined position in the middle, it is possible to prevent a safety accident caused by the child extending the body part out of the window. And the driver can concentrate on driving without worrying about the child, so he can drive safely.

When a guardian other than the driver rides with the child, the driver releases the safety mode by connecting the safety mode switch 20 to the OFF contact OFF. As described above, in the state in which the safe mode is released, the window switch 12 may be operated as in the related art to raise or lower the window between the top and the bottom.

As described above, the child protection device of the power window of the present invention opens the power window only to a predetermined position when a child rides without a guardian other than the driver, thereby preventing child safety accidents and allowing the driver to concentrate on driving safety. It is useful to contribute to driving.
