Description

Window glass opening device using water pressure sensor

The present invention relates to a window glass opening device using a water pressure sensor, and more particularly, to a window glass opening device using a water pressure sensor that automatically opens a window glass when the vehicle is flooded and sunk due to a disaster or an accident. It is about.

In general, when the vehicle is flooded and sunk while the window glass is closed by a disaster or accident, there was no separate device for automatically opening the window glass.

In rainy seasons with heavy rain these days, parked vehicles often inundate with water.

In addition, accidents due to overspeed driving on well-developed riverside roads often cause the vehicle to sink and sink.

In the event of such a disaster or accident, the occupants inside the door and window glass before the body is completely submerged in water and escape to prevent human injury.

However, there was a problem that the occupant could not open the door or the window glass due to the water pressure acting on the vehicle body due to an accident that occurred in an instant and suffocated in the cabin.

The present invention devised to solve the problems as described above has an object of preventing the injury to the passengers by opening the window glass when the vehicle body is submerged in water by a disaster or accident to escape the inside.

In order to achieve the above object, the window glass opening apparatus using the water pressure sensor according to the present invention includes: a water pressure sensing unit for detecting a signal when the vehicle is flooded more than a predetermined level and outputting a signal; It is connected to the output terminal of the hydraulic pressure sensing unit is composed of a window glass driver for opening the window glass in accordance with its output signal.

Hereinafter, a preferred embodiment of the window glass opening device using the water pressure sensor according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an installation state diagram showing a window glass opening device using a water pressure sensor according to the present invention is installed in a vehicle, Figure 2 is a block circuit diagram of the window glass opening device using a pressure sensor, Figure 3 is a water pressure according to the present invention It is sectional drawing which shows the water pressure sensor of the window glass opening apparatus using a sensor.

The window glass opening device using the water pressure sensor according to the present invention is composed of a water pressure sensor 100 and a forward and reverse rotation motor 40.

First, the water pressure sensor 100 is composed of a housing 110 and a movable contact 120.

The housing 110 has an upward opening so that water flows in, and fixed contacts 111 are installed at predetermined positions on both sides thereof.

The movable contact 120 is moved up and down by the water flowing into the housing 110 to contact / fall off the fixed contact 111 of the housing 110 and the housing member 110 with the support member 112. Connection is installed. Herein, the movable contact 120 of the housing 110 is connected to an input / output terminal of the power window down switch 20 and is configured to apply power to the other end when the movable contact 120 is in contact with the movable contact 120. In addition, the water pressure sensor 100 is installed on one side of the door 1, which is a portion where external rainwater does not flow.

In addition, the forward and reverse rotation motor 40 is installed inside the door 1 so as to open the window glass 2 by rotating according to the signal of the water pressure sensor 100, and is connected to an output end of the water pressure sensor 100. do. Here, the relay 30 is rotated forward and backward on the line of the water pressure sensor 100 and the forward and reverse rotation motor 40 according to the output signal of the power window up / down switches 10 and 20. Is installed.

Hereinafter, the operation of the window glass opening device using the water pressure sensor according to the present invention.

First, when the vehicle is inundated and sunk by a disaster or accident, water flows into the housing of the water pressure sensor 100 installed on one side of the door 1. Then, due to the weight of the water, the movable contact 120 installed in the housing 110 overcomes the elastic force of the finger member 112 and moves downward to be in contact with the fixed contact 111.

Therefore, the contact point of the relay 30 connected to the output terminal thereof is changed by the output signal of the water pressure sensor 100, and the forward and reverse rotation motor 40 is rotated to lower the window glass 2.

Therefore, the hydraulic pressure difference is less in the interior of the vehicle, and the occupant can easily escape from the vehicle.

As described above, when the vehicle is inundated and sunk due to a disaster or accident, the window glass is automatically opened so that an occupant may escape, thereby preventing accidents drowned by the occupants.
