Description

Automatic broken glass emergency escape and alarm system and vehicle

Technical field

The invention relates to a public vehicle safety system, in particular to an automatic broken glass emergency escape and alarm system and a vehicle.

Background technique

In recent years, vehicle accidents often occur, and secondary injuries after an accident often cause a large number of casualties. For example, when a vehicle falls into a water accident, the vehicle will sink into the water within 2 minutes. As the vehicle falls into the water and forms a certain water level pressure difference inside and outside the door, the possibility of driving the door to escape is almost zero, so breaking the window in this dangerous situation becomes the only escape route. When it falls into the water, it causes people to be alarmed. The probability of escaping through the physical glass is very low. When a vehicle has a fire or the like, the existing method is to use the safety hammer configured on the side window of the vehicle to smash the glass to escape, but in the event of an emergency of the vehicle, time is life, and the passenger may not know where the hammer is due to tension. , delayed his escape time. Or don't know how to break the glass and other accidents, or the power of women and children is not enough to break the glass. The strength varies from person to person, and the location of the tap depends on the common sense and experience of the occupants. As a result, the human factors that affect the success of survival are very unstable, causing some people with weaker strength or lack of vehicle knowledge to escape successfully in distress. . For high-speed operation of high-speed rail, trains, subways, urban railcars and other public transport, in order to operate safely, the side window glass is generally high in strength, and it is very difficult to break the glass with a safety hammer.

At present, the rescue facilities for passenger car accidents at home and abroad are basically the same, mainly including escape hammers, "push-pull" escape windows, "upward" escape windows and escape window breakers, but the above escape devices have deficiencies.

The escape hammer needs a lot of force when slamming the window. It is often a few times to open the window, and the glass of the window is splashed around, which is easy to cause harm to the passengers. At the same time, the hammer is stolen or not specified. Problems such as location, making it less secure;

The “push-pull” escape window is basically the same as the window of the ordinary passenger bus. The window area is small and easy to be blocked. After opening, it forms an escape space of 80cm long and 60cm wide, which is relatively crowded.

The "upward" escape window is characterized by a large escape space after opening the window, but there is no support rod positioning after pushing open, and once it is released, it will automatically close, which is very inconvenient in emergency escape, and when pushed outwards It also poses a threat to pedestrians and vehicles outside the car;

The escape window breaker is large in size, and it is inconvenient to place on the vehicle. When the passenger car encounters a sudden accident, the passenger uses the escape window breaker to break the window for a long time in an emergency.

At present, the pyrotechnic glass breaking device has been widely used because of its advantages of high breaking success rate and short use time. 200920065648.1 discloses a car escape glass breaking device. An outer casing is provided with an electronic ignition type gas generator fixed on one side of the outer casing, and an air-filled space is directly opposite to the gas outlet of the electronic ignition type gas generator, and an inflatable space and an electronic ignition type gas generator in the outer casing The tubular outlet is perpendicular to the direction of the gas outlet, and an impact block or a collision block is not installed in the tubular air inlet. During installation, the glass breaker is installed at a corner or edge of the automobile glass, and the tubular air inlet is directly opposite the automobile glass window, and the electronic ignition gas generator is connected with the automobile battery to connect the automobile battery with the detonating switch. In the event of an emergency such as a car fire or a traffic accident, the high-pressure gas rushes the impact block along the tubular air inlet to the glass window of the car or breaks the glass window of the car through the airflow shock wave; at this time, the vehicle personnel can quickly escape. It involves two technical solutions of “installing one impact block or not installing impact block”, but all have the following disadvantages:

The device has only the gas generator part, and the technical solution of not hitting the warhead has the disadvantage that, firstly, the pressure generated by the gas alone cannot reliably break the glass, and for the thicker glass (the glass used for the high-iron is generally thicker than 10 mm), And when installing, the gap between the gas generator and the glass due to the manufacturing or assembly work will leak, thereby reducing the pressure of the gas generator gas; second, the ignition tube of the gas generator is generally metal, when the gunpowder When the explosion occurs, a large amount of metal fragments are generated to the outside of the broken glass, which may cause fatal damage to personnel outside the vehicle.

The technical solution of the impact warhead has the disadvantage that the warhead has no limit structure. When the fire is detonated, the warhead will be fired at the high side of the glass, and the blasted pieces of the metal tube of the ignition tube will also be directed to the glass. On the outside, it may cause more damage to people on the outside of the vehicle.

If the automatic accident detection signal can be automatically detected, the device that automatically starts the broken glass will be greatly improved. The escape rate in the event of an accident; patent CN201420424443.9 discloses a bus side window glass self-explosion system, comprising a temperature detecting device, a temperature controller, a relay, and a glass self-explosive device mounted on the side window of the vehicle, the temperature detecting The device is installed at a corresponding position of the vehicle for detecting the temperature of the installed position thereof; the temperature controller has a signal acquisition terminal and an electric signal output terminal, and the signal output end of the temperature detecting device and the signal collection of the temperature controller The terminals are connected, and the electric signal output terminal of the thermostat is connected to the relay, and the relay is connected to the trigger portion of the glass detonator. When an emergency such as a fire occurs, the temperature of the detection position rises. When the temperature of the detection position reaches the set temperature, the thermostat sends an electric signal to automatically pull the relay, and the electric detonator of the glass detonator is energized to detonate, thereby pushing the striker. The striker on the board smashes the tempered glass to achieve automatic window breaking, which is convenient for passengers to escape in time. However, the problem is that when an accident occurs, the main system power supply (such as car battery, generator, etc.) of the vehicle will generally be powered off, and the side window glass self-explosion system will not be able to self-explosion; or because the crushing device system follows the car. Long-term bumps, cable or connector or RTD wire break, short circuit or poor contact (such as cable aging, damage, connector contact oxidation, or virtual connection caused by vibration, etc.), the system has failed.

201310013167.7 discloses a broken automobile glass breaking device, which aims to provide an automobile glass breaking device with good crushing effect. The structural principle is to heat the heating device and use the local high heat of the automobile glass to break it. 201210046572.4 also discloses a passenger car escape automatic window breaking system and a control method thereof, and belongs to the technical field of passenger car safety control. In the passenger car escape automatic window breaking system of the invention, the glass with the electric heating wire is installed on the window, and the electric heating wire is connected to the bus power supply through the main line of the power supply, and the automatic control system is arranged on the main line of the power supply. The control method for the passenger car escape automatic window breaking system of the invention compares the temperature value T, the smoke concentration value Sm, and the external impact force P in the vehicle with the preset spiritual boundary value respectively, so that the controller according to each value Process it. However, this kind of technical solution has a long heating time, generally takes 10s-20s, and has missed the best escape time in the case of fire that has been 10s-20s, and uses high-power power to heat when the vehicle is broken. After the power is not working, and when the danger occurs, the main circuit has been powered off.

In summary, in the field of public transport safety, an emergency escape and alarm system capable of automatically breaking the vehicle glass will greatly increase the secondary casualty rate in the event of an accident, and it is also urgently needed. Solved technical problems.
