TECHNICAL FIELD

[0001] The application relates to the field of passenger car emergency valves, in particular to an emergency control device for a passenger car emergency valve under abnormal environment. BACKGROUND

[0002] As an important public transportation tool, the safety of a passenger car is directly related to the life safety of passengers. An emergency valve is a key component in a passenger car safety system, and is usually used for manually opening a door or starting other emergency systems to provide an emergency evacuation channel for passengers when an emergency (such as a fire, rollover, out-of-control, etc.) occurs. However, in a real traffic accident or abnormal environment (such as night, smoke, vehicle rollover or water immersion leading to inconvenience in reaching a conventional operation position, etc.), passengers or rescue personnel often have difficulty in quickly locating and operating a conventional emergency valve. The existing emergency valve is mostly a manual mechanical type, and its operation usually requires an operator to directly pull or rotate a valve rod at a close distance, which in an abnormal environment with low visibility, limited space or critical situation, has the risk of inconvenience, long time consumption and even inability to effectively operate due to panic. In addition, the conventional valve rod lacks the ability of quick identification and remote triggering in a harsh environment, which may delay valuable rescue time.
