Background
Based on statistics, there are thousands of car fire events worldwide each year. While this is only a small percentage of the total number of cars, it still draws attention to the risk of car fires. With the continuous development of automobile technology, the popularization of new energy automobiles, electric automobiles and hybrid electric automobiles increases some new fire risks. Conventional engine fires may be caused by a variety of causes, such as electrical wire aging, damaged electrical circuitry, improper electrical repair or installation, etc., causing electrical system failures to short or overheat and ignite nearby flammable components or leaking fuel, or by leaking fuel pipes or connections in the fuel system, leaking fuel or dripping, or by cooling system failure, water pump failure, coolant leakage or starvation, etc., causing nearby components or liquids in the engine to burn and fire. For electric vehicles, it is common for a fire to be caused by battery aging, battery damage due to various causes such as collision or breakage, battery overheating or short-circuiting due to malfunction of a charging system or erroneous maintenance of the battery, or for a fire to be caused by sparks and open fires due to short-circuiting, spark breakdown, worn electric wires or electric parts, etc. Thus, in response to these concerns, automobile manufacturers, government authorities and fire departments are constantly striving to improve the safety of automobiles and to establish corresponding safety standards and regulations, but at present, higher requirements are mainly put on technical standards of automobile host factories and products of parts per se, but once an automobile fires, passengers can only find out in time and use a self-rescue mode (using an automobile fire extinguisher or calling a fire fighter) in hope, but in general, once the automobile fires, the fire easily spreads rapidly and easily, causing huge property loss and personal injury. These have created a great market need for fire prevention or early action.

Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples
In a specific embodiment, as shown in fig. 1, a safety protection device for automobile driving safety comprises a controller 1, a battery pack 2, a gas generator 3, a pipeline 4, a plurality of temperature sensors 5, a control line 6 and a one-way pressure release valve 7; the gas generator 3 comprises an igniter; the gas generator 3 is connected with a pipeline 4; the temperature sensor 5 detects the temperature of the battery pack 2 and transmits a signal to the controller 1, and the controller 1 controls the igniter through the control line 6; the controller 1 is connected with the temperature sensor 5 through a control line 6, a plurality of fire extinguishing agent outlets are arranged on the pipeline 4, and the fire extinguishing agent outlets are sealed through adhesive tapes 8; the pipeline 4 is arranged inside the shell of the battery pack 2; the pipeline 4 is filled with fire extinguishing agent which is a mixture of calcium salt and gel fire extinguishing agent. Many electric vehicles use lithium batteries as a power source, lithium is a high-activity metal, and conventional fire extinguishing agents cannot extinguish such fires. Thus, the present example uses a mixture of calcium salt and gel fire extinguishing agent as the fire extinguishing agent to extinguish fires in lithium ion batteries. The gel fire extinguishing agent in the embodiment isThe gel fire extinguishing agent is sold by Oko-Tec and is in powder form, and can generate colloidal liquid with very high fire heat absorption capacity in a short time. The gas generator 3 is filled with high-pressure inert gas for preventing or extinguishing fire, and the inert gasThe gas is a mixture of helium and argon, and the mixed gas comprises 98% of argon and 2% of helium.
In this embodiment, the controller 1 is an ECU.
The embodiment is used in combination with a battery management system of an electric automobile and is used for explosion prevention or ignition delay of a battery of the electric automobile.
In this embodiment, the temperature sensors 5 detect the temperature in the battery pack 2 in real time and transmit temperature information to the controller 1 in real time, the controller 1 continuously acquires the temperature data of the battery pack 2 from the temperature sensors 5 and continuously analyzes the data, and when the temperature exceeds the safe temperature, the controller 1 sends a fire signal to the gas generator 3 and starts the igniter on the gas generator 3.
After start-up, the high pressure inert gas in the gas generator 3 expands and enters the conduit 4.
Most of the pipes 4 in this embodiment are braided hoses. The end of the pipe 4 is fixedly connected with the gas generator 3. When the igniter is started, after the high-pressure inert gas expands into the pipeline 4, the internal pressure of the pipeline 4 is increased, the adhesive tapes 8 of a plurality of fire extinguishing agent outlets arranged on the pipeline 4 are flushed away, and the internal fire extinguishing agent is sprayed out from the fire extinguishing agent outlets and uniformly covered in the battery pack 2, so that the time from the battery fire or the engine fire to the non-collection condition can be effectively delayed, the fire can be extinguished under a certain condition, and the safety of a driver and passengers is effectively ensured.
Meanwhile, in order to prevent the pressure of the inside of the battery pack 2 from rising due to the entering of inert gas, the adhesive tape 8 in the pipeline 4 cannot be flushed out due to insufficient internal and external pressure, in this embodiment, the one-way pressure release valve 7 is arranged on the shell of the battery pack 2, when the controller 1 activates the igniter on the gas generator 3, the one-way pressure release valve 7 is also activated to be opened, so that the gas in the battery pack 2 is discharged through the one-way pressure release valve 7, the pressure in the battery pack 2 is reduced, the outlet on the pipeline 4 is flushed out more completely, the fire extinguishing agent is covered more uniformly, and the explosion prevention or fire delay effect is better.
The embodiment is used for protecting the battery safety of the electric automobile, but the invention can also be applied to the fire prevention and explosion prevention of the engine, the oil tank and the oil pipeline of the traditional automobile. The principle of protection is similar to the present embodiment.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
