Automatic fire extinguishing system for electric vehicle parking space

An automatic fire extinguishing system for a parking space of an electric vehicle, the automatic fire extinguishing system comprising:

• a thermal runaway isolation system, configured to isolate the parking space;
• a detection system, installed inside a battery pack of the electric vehicle and configured to perform fire monitoring inside the battery pack;
• a medium system, disposed outside the parking space;
• and
• a fire control access system, wherein one end of the fire control access system extends into a vehicle body of the electric vehicle and is joined to an inside of the battery pack, wherein another end of the fire control access system extends out of the vehicle body of the electric vehicle and is connected to the medium system;
• wherein the fire control access system comprises a transfer pipe and a quick insertion joint mechanism disposed on the transfer pipe, the quick insertion joint mechanism being configured for connection and disconnection between the battery pack of the electric vehicle and the medium system;
• wherein the battery pack of the electric vehicle is joined to the medium system when the electric vehicle is parked on the parking space, and is disconnected from the medium system when the vehicle parked in the parking space is leaving;
• wherein the quick insertion joint mechanism comprises a quick joint A and a quick joint B, an installation cavity A is defined in the quick joint A, a first valve core is disposed in the installation cavity A, one end of the first valve core extends out of the installation cavity A, a first spring is sleeved over another end of the first valve core, the first valve core and the first spring are configured for implementing opening and closing of the quick joint A;
• wherein an installation cavity B is opened in the quick joint B, a second valve core is disposed in the installation cavity B, one end of the second valve core extends out of the installation cavity B, a second spring is sleeved over another end of the second valve core, the second valve core and the second spring are used for implementing opening and closing of the quick joint B, when the quick joint A is connected to the quick joint B, the quick joint A and the quick joint B are both in an open state, and the quick joint A is communicated with the quick joint B;
• wherein the first valve core comprises a first tip extending out of the installation cavity A, and the second valve core comprises a second tip extending out of the installation cavity B;
• and wherein when the quick joint A is connected to the quick joint B, the first tip and the second tip are in contact and push against each other thus causing the first tip to retract into the installation cavity A and compress the first spring, and causing the second tip to retract into the installation cavity B and compress the second spring, such that the quick joint A and the quick joint B are both in an open state, and the quick joint A is communicated with the quick joint B.
