an emergency escape system

Abstract

The invention relates to the technical field of vehicle safety emergency equipment, in particular to an emergency escape system. The emergency escape system comprises a built-in gas circuit mechanism, a system shielding valve, an electromagnetic valve and a vehicle door mechanism which are connected in sequence, wherein the electromagnetic valve is used for controlling the vehicle door mechanism to be started and shut down; an emergency gas circuit mechanism is connected in parallel between a forced door opening of the electromagnetic valve and the built-in gas circuit mechanism; the emergency gas circuit mechanism is connected with the system shielding valve; the system shielding valve is used for controlling the emergency gas circuit mechanism to be started and shut down according to the on / off state of the built-in gas circuit mechanism. By adopting the emergency escape system, the start and shutdown of the emergency gas circuit mechanism can be controlled according to the on / off states of the circuit and the gas circuit of the built-in gas circuit mechanism, so that rapid and reliable automatic starting of the vehicle door mechanism can be realized in the presence of power and gas, in the presence of power and absence of gas, in the absence of power and presence of gas, and in the absence of power and gas, and immediate escape of people in the vehicle is ensured; when the vehicle door mechanism is in a normal state, the system can shield automatically; the emergency escape system has the characteristics of sensitive reaction, short door opening time, safety, reliability and the like.

technical field [0001] The invention relates to the technical field of vehicle safety emergency equipment, in particular to an emergency escape system. Background technique [0002] Along with the development of society now, the country vigorously develops public transportation in order to facilitate people's travel, and bus has become a necessary means of transportation for people's travel, but public transportation accidents have also increased significantly in recent years, such as Xiamen BRT (Bus RapidTransit, Chinese name For rapid transit system) bus fire incidents, Chengdu bus fire incidents, Guizhou bus fire incidents, etc., if the doors of the bus cannot be opened in the shortest time when the bus is on fire, the people will not be able to escape in the shortest time, and the consequences will be that they cannot Imagine that at least 48 people died in the Xiamen BRT bus fire incident.

[0002] Along with the development of society now, the country vigorously develops public transportation in order to facilitate people's travel, and bus has become a necessary means of transportation for people's travel, but public transportation accidents have also increased significantly in recent years, such as Xiamen BRT (Bus RapidTransit, Chinese name For rapid transit system) bus fire incidents, Chengdu bus fire incidents, Guizhou bus fire incidents, etc., if the doors of the bus cannot be opened in the shortest time when the bus is on fire, the people will not be able to escape in the shortest time, and the consequences will be that they cannot Imagine, for example, the Xiamen BRT bus fire that killed at least 48 people

[0003] Existing buses are equipped with door emergency valves at the driver and the doors, which are used to open the doors when an emergency occurs, but the effect is not ideal. It cannot be opened or the opening time is too long, and the best escape time is missed, resulting in casualties of passengers. This is mainly because the emergency valve cuts off the air circuit connected to the door, and then manually pulls the door open to realize the safety of the door. It takes a certain amount of time to shut off the air circuit of the door, and the longest time to open the door manually after the air circuit is shut off is as long as 10 seconds, and the vehicle fire is triggered, so how to open the door quickly is up to the passengers The key to emergency escape

[0004] In addition, because the air circuit cut-off usually requires electric control support, when the vehicle is on fire and the power is cut off, the solenoid valve usually cannot be switched normally, resulting in the door being unable to open, causing the passengers in the car to miss the best escape time
