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.
Specifically, when the air tightness of the battery pack body 10 is lowered, the push block 254 moves in the direction of the battery pack body 10 under the reaction force of the second spring 253, the movement of the push block 254 makes the inside of the second air extraction tube 252 positioned at the rear end portion of the push block 254 extract air from the first air extraction tube 251 communicated with the push block 254, in other words, the inside of the first air extraction tube 251 extracts air from the first air extraction tube 241 communicated with the first air extraction tube 251, in other words, the air at the upper end of the air blocking tube 243 is extracted, under the action of air pressure, the one-way valve 244 positioned at the lower end of the air blocking tube 243 extracts air from the outside of the fixed shell 21 into the first air extraction tube 241, and the air blocking tube 243 ascends in the direction approaching the first air extraction tube 251 under the action of air flow, when the lower end of the air blocking tube 243 is far away from the connecting port between the mounting tube 231 and the second air extraction tube 242 and the first air extraction tube 241, the mounting tube 231 is communicated with the second air extraction tube 242, in other words, the high-pressure inert air blocked inside the mounting tube 231 will pass through the first air extraction tube 241 and the second air extraction tube 241 and the high-pressure inert gas is blocked inside the mounting tube 242, and the high-pressure inert gas is introduced into the battery pack body 10, and the air tightness of the air can be lowered, and the air can be combusted, when the air can flows inside the charging apparatus, and the battery pack body, and the air can be filled.
When the high-pressure inert gas enters the battery pack body 10 through the mounting cylinder 231, the air flow drives the fan blades 235 and the rotating rod 233 to rotate, so that the coil 234 on the rotating rod 233 rotates rapidly to cut the magnetic induction lines formed among the magnets 238, and current is generated in the conductive paths formed by the electric connection of the coil 234, the first conductive ring 236 and the second conductive ring 237 and the signal transmitter 26, so that the signal transmitter 26 transmits a warning signal by a vehicle-mounted system, and a driver and a passenger can quickly find the situation and escape from the vehicle for danger.
When the vehicle is serviced, pressure is again applied to the stopper 2233 so that it is retracted into the stopper case 2231, and then the gas tank is removed and the safety guarantee mechanism 20 is completely disassembled. Because the connection mode of the safety guarantee mechanism 20 and the battery pack body is detachable, the convenient and quick disassembly of the safety guarantee mechanism 20 can be realized, and the vehicle maintenance efficiency is further improved. When the air extraction assembly 25 is exposed, the push rod 255 is manually rotated to be inserted into the second air extraction pipe 252 to limit the push block 254, so that the push block 254 is prevented from moving in the vehicle maintenance process, the whole device is not triggered in the vehicle maintenance process, and normal maintenance of the vehicle is ensured. In another embodiment, the design of the push rod 255 may be eliminated to increase the sensitivity of operation of the air extraction assembly 25, and the push block 254 may be manually reset during vehicle maintenance when the device is triggered so that it does not interfere with vehicle maintenance or subsequent use of the device.
In summary, by arranging the safety guarantee mechanism on the battery pack body, the use environment of the battery can be continuously maintained when the air tightness of the battery pack body is attenuated, the occurrence probability of potential safety hazards such as battery ignition and the like is reduced or the influence of the battery ignition is weakened, and the safety of drivers and passengers is guaranteed. Specifically, the carrier gas component is arranged to realize convenient replacement of the gas tank, so that the gas pressure of the gas tank is ensured to be sufficient in the use process, and the gas charging component and the gas exhausting component can normally operate, thereby realizing maintenance of the use environment of the battery when the battery pack body is damaged and leaked, reducing the occurrence probability of potential safety hazards such as battery ignition and the like or weakening the influence of the battery ignition; through set up power supply module between carrier gas subassembly and inflation subassembly, and power supply module and signal transmitter electric connection for the safety guarantee mechanism can be under the independent power supply's of no external power source condition, guarantees signal transmitter's normal operating, can in time send the signal of taking shelter from danger to on-vehicle system, makes the driver and passengers discover the condition in time and take shelter from danger. Meanwhile, the safety guarantee mechanism is detachably connected to the battery pack body, so that the safety guarantee mechanism can be quickly and conveniently detached comprehensively when the battery pack body is overhauled, the service performance of a subsequent safety guarantee device can be guaranteed, overhauling of the battery pack body is not influenced, and the driving safety guarantee of drivers and passengers is indirectly improved.
