In the actual operation process, the specific use process of the novel energy automobile driving safety guarantee device can be as follows: the signal transmitter 26 is adapted to the in-vehicle system such that signals transmitted by the signal transmitter 26 can be received and displayed by the in-vehicle system. The stopper 2233 is compressed to be retracted into the stopper case 2231, and then the high-pressure gas tank filled with the flame-retardant non-toxic inert gas is inserted into the sleeve seat 2221 on the second bracket 222 through the sleeve 2211 on the first bracket 221, the stopper 2233 is loosened, and the stopper 2233 is rebound and reset under the reaction force of the first spring 2232, so that the high-pressure gas tank is limited, and the high-pressure gas tank is fixed in the accommodating space formed between the first bracket 221 and the second bracket 222. In the process of inserting the high-pressure gas tank into the sleeve seat 2221, the poking needle 2242 in the pipe orifice of the connecting pipe 2241 extrudes the valve of the gas tank, the valve of the gas tank is opened, high-pressure gas in the gas tank enters the mounting cylinder 231 through the connecting pipe 2241 and the gas pipe 2243, and as the gas tightness of the battery pack body 10 is perfect, the gas blocking block 243 is positioned at the connecting port among the mounting cylinder 231, the second gas charging pipe 242 and the first gas charging pipe 241, and the gas is blocked by the gas blocking block positioned in the first gas charging pipe 241 and cannot enter the battery pack body 10.
When the shell of the battery pack body 10 is damaged and leaked to cause the air tightness of the battery pack body 10 to be lowered, the air extraction assembly 25 extracts air from the air inflation assembly 24, the air blocking block 243 ascends under the action of air flow, the communication ports among the mounting cylinder 231, the second air inflation tube 242 and the first air inflation tube 241 are not blocked, high-pressure air in the air tank enters the battery pack body 10, the possibility of burning of the battery in the battery pack body 10 is reduced, the probability of expanding fire is reduced, and the safety of drivers and passengers is ensured.
