If people are injured or unconscious, serious loss of life and property will occur if the fire source is not cut off in time. This device will first release the battery from the bottom of the chassis when a fire or impact that affects the battery structure occurs, first separating the car body from the battery.

The emergency ejection mechanism can quickly eject the battery pack to prevent the battery pack from falling smoothly, and finally prevent the fire from spreading to the entire vehicle, thereby improving the safety of new energy vehicles.

[0068] In an embodiment of the present invention, Figure 1-5 As shown, it also includes: a protective plate, which is fixedly installed between the tops of a pair of chassis side beams 1.
[0069] Implementation process: When the battery pack 4 is hit or directly catches fire, the second electromagnetic slider 18 moves first and slides downward along the second guide slide 17. At this time, a pair of lifting rods 19 that limit the lock block 7 move downward. Since the lock block 7 loses the limit of the lifting rod 19, the lock block 7 can rotate at this time. Then the first electromagnetic slider 9 moves and slides along the first guide slide 8, and pulls the lock block 7 to a position that coincides with the projection of the sliding seat 6 and the installation cylinder 5. At this time, the lock block 7 can drive the sliding seat 6 and the installation cylinder 5 to slide downward, and then the battery pack 4 is detached from under the pair of chassis side beams 1. At this time, the connecting rod 11 slides in the intermediate cylinder 12, and the intermediate cylinder 12 is in the bottom cylinder 13, at this time, the battery pack 4 is suspended at the bottom of the chassis side beam 1. Since the impact sensor is connected to a delay device, the airbag 20 can pop out two seconds after the impact, leaving time for the unlocking of the lock block 7. At the same time, when the battery catches fire, the flame sensor 26 will transmit the information to the wireless solenoid valve 22. At this time, the wireless solenoid valve 22 opens, and the water-based foam inside the fire extinguishing tank 14 is sprayed out from the nozzle to the upper surface of the battery pack 4. When the fire point is on the lower surface of the battery pack 4, the water-based foam on the upper surface of the battery pack 4 becomes liquid and flows along the guide hole 23 to the guide groove on the lower surface of the battery pack 4. At this time, the lower surface can be cooled to prevent the battery from re-igniting.
[0070] The first electromagnetic slider 9, the second electromagnetic slider 18, the wireless electromagnetic valve 22, the impact sensor and the flame sensor 26 all use independent power supplies and are not electrically connected to the battery pack 4 in the car, so as to prevent the battery pack 4 from catching fire, deforming, or being disconnected from the electrical components after leaving the car, causing the electrical components to malfunction.
