The utility model discloses generally set up the afterbody at the vehicle for provide warning information to the rear car that comes, inform rear car the place ahead that accident vehicle takes place occupy, please slow down and walk slowly. Existing vehicles are equipped with warning signs and need to be manually placed at a specified distance.

However, in some accidents, passengers and drivers in the automobile cannot get off the automobile by themselves to place the automobile, or lose consciousness or lose autonomous action capability, and then the marks are not placed in time, so that secondary accidents are easily caused.

The utility model discloses a structure is then an urgent auto-eject device, can detect after the collision accident synchronous start and pop out fast at the vehicle, and action part wherein is thrust unit promptly, and identification module is in same space with this structure to be equipped with the opening on one side of this space. When the identification module is pushed to have a certain initial speed, the original limit structure arranged on the opening can be broken through, and the identification module flies out for a certain distance.

It should be noted that the flying distance is determined according to the actual vehicle and the relevant laws and regulations, and the distance for placing the warning mark is specified in the general road safety traffic law, and the range is beyond one hundred fifty meters of the fault vehicle. But manual sign can independently control and put the distance, and this the utility model provides an identification module's departure distance is limited, if need reach more than 150m, then need adopt the great thrust unit of volume, and because the release initial velocity is higher, can cause the influence to the rear object.

And a pushing device and an identification module are arranged in the tank body 1, the two parts are in a close-fitting state, the pushing device is fixed at the bottom in the tank body 1, and a cable in the pushing device penetrates out from the bottom of the tank body 1 and is connected with external equipment.

As can be seen in fig. 4, the pushing device has an overall cylindrical structure, which is the same as the starting device of the conventional airbag 13, and a filling bin 8 with a large volume is arranged inside, and the filling bin 8 is filled with a sodium azide material.

The outside of the filling bin 8 is of an annular filtering bin 7 structure, and the inside of the filling bin is filled with compact filtering cotton, so that the flue gas sprayed by sodium azide during severe reaction is prevented from carrying a large amount of particulate matters.

The outer wall of the filling material bin 8 is provided with a plurality of communicating holes 8.1 which are communicated with the filtering bin 7 through the communicating holes 8.1. As can be seen in fig. 5, the communication holes 8.1 are elongated through hole structures, and are distributed on the outer side wall of the packing bin 8 at equal central angles, so that the air guide effect is improved by arranging enough air guide holes.

While the middle of the silo 8 has a cylindrical space for receiving the structure of the igniter 6 inserted from its bottom. The igniter 6 is essentially a detonator structure that receives an electrical signal to generate energy to cause the sodium azide to react violently to release nitrogen.
