Description

Suffocation prevention device in vehicle

The present invention relates to a device for preventing suffocation of infants in a vehicle, and more particularly, in a child lock state in which a door does not open even when a door handle is pulled from the inside of a vehicle due to operating a child lock mechanism installed at a side of the door. When the inner handle (ie, the door handle in a car) is pulled, the window is lowered automatically so that the young children ride or play around in the back seat, and the door is closed and the child lock is engaged. It is invented to prevent the inflow of the problem leading to safety accidents such as choking.

Conventional child lock systems are designed such that the door does not open even if the rear door handle is simply pulled inside the vehicle.

In other words, if the door is closed while the child lock switch (mechanical switch) on the side of the rear door is operated, the link is locked inside and the inner handle does not work. It is configured not to.

However, such a configuration does not allow the doors to open even when the children pull the rear handles. Therefore, when children are inadvertently left in the car during the summer, or when the children enter the car with mischief, the door of the vehicle does not open. There is a problem that often happens that the suffocation accident occurs because the air is not circulated with each other.

The present invention has been made to solve such a conventional problem, and is interlocked with a child lock switch made of a mechanical component and a time relay switch operated by a door handle separately from the original window switch between the battery and the window motor. Another electronically operated child lock switch is installed in series so that if the door handle is pulled by a child or the like while the child lock is engaged, the window opens automatically due to the operation of the time relay switch separately from the window switch. The purpose of the present invention is to provide a device for preventing the suffocation of babies in a car that can prevent the occurrence of suffocation accidents due to blocking the circulation of air and the room.

An object of the present invention described above, a window switch having a forward and reverse switching function between the battery and the window motor is connected in series, the window side and the door opening and closing of the vehicle provided with a child lock switch that is mechanically interlocked with the door lock system A device comprising: a series of time relay switches operated by a door handle between the battery and a window motor and another child lock switch which is electronically operated in association with the mechanical child lock switch. Can be.

Therefore, even if the door is closed while the child lock is engaged, if the door handle is pulled slightly in the car, the voltage of the battery is supplied to the window motor through the time relay switch and the child lock switch separately from the window switch, and the window is automatically opened. Since the indoor and outdoor air can be circulated through the open window, the window cannot be opened in the state of child lock in summer, thereby preventing the suffocation of the occupant.

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

Fig. 1 shows a circuit diagram of the device of the present invention, Fig. 2 shows a door perspective view of a vehicle in which the device of the present invention is implemented, and Figs. 3 (a)-(c) show a schematic block diagram of each switch. will be.

According to this, a window switch 3 having a forward and reverse switching function is connected in series between the battery 1 and the window motor 2, and a side lock of the door 5 includes a child lock switch which is mechanically interlocked with the door lock system. In the window and door opening and closing device of the car 4) is installed,

On the inner side of the door handle 6 is provided a time relay switch 8 which is operated in response to the amount of rotation thereof, and on one side of the child lock switch 4 another child which is electronically on / off operated in conjunction with its operation. The lock switch 7 is installed, but the time relay switch 8 and the other child lock switch 7 are connected in series between one side of the battery 1 and the window motor 2. do.

Referring to the operation and effect of the device of the present invention configured as described above in detail.

First, the child lock switch 4 installed in the side portion of the door 5 and the electronic child lock switch 7 interlocked with the child lock in a state of being made of mechanical components in a normal state in which the child lock is not engaged. Is “off”, the window motor 2 does not operate at all even if the time relay switch 8 operated by the door handle 6 is “on” and has a forward and reverse switching function as in a typical vehicle. In response to the operating position of the window switch 3 installed inside the door in the form as shown in (c), the window motor 2 is driven in the forward or reverse direction so that the window is opened or closed, as well as the door itself. You can open it at.

On the other hand, when the children are in the back seat while the children enter the back seat while playing or joking, the child lock is locked, so as to protrude from the side of the door 5 as shown in FIG. The child lock switch 4, which is a mechanical component provided, maintains the "on" state of the electronic child lock switch 7 provided above.

In such a state, when a young infant or the like in the vehicle pulls the door handle 6, the time relay switch 8 installed around the hinge portion of the door handle 6 as shown in FIG. On ", the output voltage of the battery 1 is supplied to the window motor 2 through the child lock switch 7 and the time relay switch 8 so that the window is automatically opened.

That is, the door handle 6 of the rear door plays the same role as the window switch 3 so that the door itself is not opened but only the window is lowered.

At this time, the time relay switch 8 has a function of supplying the voltage of the battery 1 to the window motor 2 until the window is completely opened once the door relay 6 is “on”. Even if you pull it a little, the window will open completely, and the window will be closed in the state of child lock in summer to prevent the occurrence of safety accidents such as choking that can be caused by blocking the flow of internal and external air.

As described above, according to the present invention, a time relay switch operated by a door handle and another child lock switch “on” in addition to the original window switch are additionally installed between the battery and the window motor in series. Therefore, when a child or a child pulls the door handle in a differential vehicle in the summer when a child lock is engaged, the window is automatically opened due to the operation of the time relay switch separately from the window switch. It is possible to secure the stability of the car, such as to prevent in advance.
