Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Technical field to which the invention belongs] Submergence accidents are extremely rare among car accidents, but the death rate is said to be extremely high even though it is one of the few accidents. It is thought that driving mistakes by driving or the elderly are relatively common, leading to the occurrence of accidents falling to rivers, lakes, the sea, etc.In this case, it is important how quickly you can escape from a vehicle submerged in water, In addition, submersion accidents are not limited to reckless driving, elderly people, etc., and it is not clear when and where they will encounter, but in any case, they are upset and the escape method often stops flashing. As a countermeasure, a device for forcibly opening the window glass is required, which is a field of the automobile industry where safety is ensured.

[0002]

2. Description of the Related Art As a method of escaping when a vehicle is submerged, a driver and each person in the same vehicle manually open the glass of a vehicle window or break the glass with a hammer or the like to escape.

[0003]

SUMMARY OF THE INVENTION There is no need to operate a switch as a means for a driver and a passenger to open the vehicle window when the vehicle is submerged or to break the vehicle window glass, and the vehicle window is quickly and automatically forcibly submerged after the vehicle is submerged. The opening of the glass allows easy escape in a short time.

[0004]

The device for detecting and operating the water pressure when the vehicle is submerged is installed at the center of the outside of the automobile or at the bottom of the vehicle. Even if absolutely water pressure is applied, it is an essential condition of the task. As a device, a switch circuit operated by water pressure and a switch for opening the vehicle window glass opening motor installed on the vehicle door are forcibly connected, and The purpose is to provide a device for opening the glass window of a car by a voltage booster circuit that operates at a speed twice the normal use speed.

[0005]

[Function] In the event of a car or vehicle submergence, if the driver and his / her passenger are upset and the act of opening the vehicle window is delayed, the water pressure will be rapidly accelerated after the vehicle submerges, making it difficult to open the door and vehicle window. At present, it is not possible to confirm the location of the hammer when breaking the glass due to the fact that it is normal, and because it is underwater, the electrical system is likely to fail, so the fuse cut, switch This device causes an unexpected accident due to malfunction of the circuit, etc. This device is a power supply side of the motor for opening the window glass on the electric wiring of the vehicle through a switch circuit with a magnet that operates by water pressure when the vehicle is submerged. By providing a voltage booster circuit connected in parallel to the above, by the operation of the magnet switch circuit, by adding the high output voltage to the motor for opening the vehicle window glass,
Its motor rotates at double speed and the opening time of the window glass is much faster than the normal opening time, which means that escaping from the submerged car as soon as possible reduces the risk of life, especially at night. The effect is great for vehicle submersion accidents that occur.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS By installing this device on the outer bottom surface of an automobile, it is possible to open the window glass at the time of submersion of all sides of the vehicle regardless of the angle, location, etc. of the vehicle when submerged. By applying a boost voltage to the motor for opening, the speed at which the glass opens can be increased quickly and escape in a short time.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS This apparatus is horizontally fixed by a cylindrical outer container (FIG. 1-1) on the bottom part of an automobile and a clasp (FIG. 1-3) on the bottom of a vehicle body. The bellows hood is attached to the bellows guide frame 1-13 inside the cylindrical outer container, and the center part of the cylindrical outer container FIG. 1-1, and FIG. At the other end of the bellows hood is provided a hydraulic membrane FIG. 2-12, and at the center on the diameter of the membrane is fixed a metal magnet side support bar FIG. 1-11, at the tip of the support. Metal is processed into a bowl shape and a part is provided with a permanent magnet (FIG. 1-6). A bellows hood (FIG. 2-7) is a metal spring having a spring function at the center of the diameter of the hydraulic film at the other end. Attach the strut diagrams 1-15. Attach a spherical iron piece Fig. 1-14 to the tip of this support,
Furthermore, in order to efficiently increase the water pressure applied to the bellows hood when water enters, the bellows hood and the cylindrical outer container are shown in FIG.
In order to secure the airtightness, apply a soft rubber packing (Fig. 2-8) circumferentially to the area where the bellows hood and the cylindrical outer container are in contact with each other. 2-17, use the water pressure of the water that intrudes from it. In this case, to increase the water pressure, a water receiving port whose center is thinned is provided. When pressure is applied to the hydraulic membrane applied to the bellows hood as shown in FIG. 2-12, the bellows hood is fixed at the center of the bellows hood fixed to the inside of the cylindrical outer container. When this state progresses, the magnet surface comes into contact with the other iron surface, and the ends contact in this way.The lead diagram from the metal part of each support attached to the hydraulic membrane part of this device 1-2
