1 is a logic block diagram of a glass auto-breaking escape system in accordance with one embodiment of the present invention. As shown in FIG. 1, the glass automatic breakage escape system includes a central control center 10, an inductor 14 and a glass automatic crushing device 12. The sensor 14 senses the occurrence of an emergency and transmits an inductive signal to the central control center 10. For example, the sensor 14 can be a temperature sensor or a smoke sensor to sense the temperature or smoke concentration of the environment in which it is located. The central control center 10 receives and analyzes the sensing signal transmitted by the sensor 14, and determines whether an emergency has occurred according to a preset condition. When the sensing signal transmitted by the sensor 14 exceeds a preset condition, the central control center 10 generates a control signal to activate the glass automatic breaking device 12, thereby instantaneously breaking the glass. A detailed description of the specific structure of the glass automatic crushing device 12 will be given later.

Further in the embodiment shown in FIG. 1, the glass auto-crush escape system of the present invention may further be provided with a manual activation switch 16 to manually activate the auto-glass breaking device 12 when, for example, the inductor 14 fails. The manual activation switch 16 can generate an activation signal to the central control center 10 to cause the central control center 10 to generate a control signal to activate the glass auto-crushing device 12. Optionally, the glass automatic breakage escape system may further be provided with a fault indicator light 18 for displaying whether the system is operating normally according to the self-diagnosis result of the central control center 10.

2 and 3 are logic block diagrams and circuit implementation schematic diagrams of an automatic glass breakage escape system in accordance with another embodiment of the present invention. The system has a structure similar to that of the embodiment shown in FIG. 1, including a central control center 10, a temperature sensor 241, a smoke sensor 242, a glass auto-crushing device 12, and a manual activation switch 16 and a fault indicator light 18. In the embodiment shown in Figures 2 and 3, the glass auto-breaking escape system is provided with a temperature sensor 241 to sense the temperature of the environment (e.g., within the bus) and provide a temperature sensing signal to the central control center 10. The glass auto-breaking escape system also provides a smoke sensor 424 to sense the concentration of smoke in the environment (e.g., within the bus) and provide a smoke concentration sensing signal to the central control center 10.

As further shown in FIG. 3, the central control center 10 includes a signal collection processing module 102 and a start switch 104. The signal collection processing module 102 is configured to analyze and compare whether the sensing signal transmitted by the sensor exceeds a preset condition. When the signal collection processing module 102 analyzes and finds that the signal sensed by at least one of the temperature sensor 241 and the smoke concentration sensor 242 exceeds a predetermined condition (eg, overheating or excessive smoke concentration), it is determined that an emergency has occurred. . At this time, the signal collection processing module 102 sends a trigger signal to the start switch 104. After the start switch 104 receives the trigger signal from the signal collection processing module 102, the power of the glass auto-crushing device 12 is turned on immediately, and the glass auto-crushing device 12 is activated, as shown in FIG.

Referring further to FIG. 3, the manual activation switch 16 can also generate a start signal to the start switch 104 to cause the start switch 104 to turn on the power to the glass auto-crusher 12. The fault indicator light 18 of the central control center 10 can be an LED light to indicate whether the system is working properly. The self-diagnosis indication of the fault indicator can be implemented by various commonly used means in the prior art, and thus will not be described in detail in this application.

4a and 4b are schematic views of a glass automatic breakage escape system of the present invention for use in a bus. As shown, a plurality of sensors 43 (four shown in the figure) are distributed on the roof of the bus 40. For example, the plurality of sensors 43 can include a temperature sensor and a smoke concentration sensor. Further, in the lower portion of each of the tail glass 41, the right side glass 42, the left side glass 45, and the head glass 46 of the bus 40, glass automatic breaking devices such as glass automatic

breaking devices

44a and 44b are provided. When the temperature of the interior of the vehicle is sensed by the sensor 43 of the roof and the concentration of the smoke is too high, the central control center immediately generates a control signal to activate the automatic glass breaking device disposed on each glass to break the glass, and the passenger inside the vehicle.

Figure 5 is a schematic view showing the structure of an automatic glass breaking device according to an embodiment of the present invention. In the embodiment shown in FIG. 5, the glass auto-crushing device includes a housing 122 filled with a gas generating agent 124. Further, an igniter 128 is further provided in the casing 122 to be electrically connected to an external power source. For example, the igniter 128 can be an igniter composed of two electrically separated electrical contacts and a high-resistance conductive material connecting the two electrical contacts. When a predetermined voltage is applied to the two electrical contacts, the igniter generates sufficient The heat causes the ignition material on the igniter (for example, potassium nitrate boron BKNO ₃ ) to ignite. The ignited igniting material in turn introduces the gas generating agent 124 to instantaneously generate a large amount of gas. For another example, the igniter 128 may be two electrodes electrically connected to an external power source. When a predetermined voltage is applied to the two electrodes, the spark generated by the discharge of the two electrodes ignites the gas generating agent filled in the housing 122. 124, a large amount of gas is generated instantaneously. Igniters and gas generating agents which may be suitable for use in the present invention are well known to those skilled in the art and will not be described in detail herein.

Also, the side of the casing 122 facing the glass to be crushed is provided with an exhaust port 126 so that the high-pressure gas generated instantaneously in the casing 122 is directed to be ejected, thereby crushing the front glass. The exhaust port 126 is sealed by a seal in a non-operating state to prevent the gas generating agent 124 filled in the housing 122 from falling out. For example, the exhaust port 126 may be sealed by an aluminum foil, and when the gas generating agent 124 is ignited to generate a large amount of gas, the high pressure of the gas may be blown out of the aluminum foil and ejected from the exhaust port 126.

In the embodiment shown in FIG. 5, the vent 126 is disposed at an end opposite the igniter 128. The vent 126 may be provided by an exhaust pipe extending from the housing 122 to provide an orientation for gas ejection to enhance the impact of gas escaping. Figure 5 shows an example of an automatic glass breaking device according to the present invention, and it will be apparent to those skilled in the art that in various other embodiments, the housing can have a variety of different shapes, as well as the venting opening. It may have various shapes, and the exhaust port may be disposed at any position on the casing as long as the glass automatic crushing device is installed and the exhaust port faces the glass to be crushed.

As mentioned above, in the event of an emergency such as a fire, the central control center makes a judgment based on the sensing signal transmitted by the sensor, and generates a control signal to activate the automatic glass breaking device, that is, the power of the igniter is turned on, so that the igniter ignites the gas. The generating agent, the instantaneously generated high-pressure gas is directionally ejected from the exhaust port to break the glass. Therefore, the above glass automatic crushing device of the present invention can automatically crush the glass of the bus at the first time when an emergency such as a fire occurs, thereby facilitating the escape of the passenger inside the vehicle.

The above description is only for the specific embodiments of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention. within.
