Lithium batteries are frequently used in electric automobiles, and in recent years, with the hot sales of electric automobiles, the accidents of battery combustion and explosion frequently occur. Lithium ion batteries are widely used due to their high energy density. However, lithium ion batteries have poor high temperature resistance and overcharge resistance, and internal short circuit and fire caused by thermal runaway often occur. Further, since a large amount of active materials are contained in the lithium ion battery and the active materials undergo a violent chemical reaction when they come into contact with air, accidental knocking of the lithium ion battery is a physical property thereof. The explosion of the batteries of the electric automobile is prevented from affecting people in the automobile and burning the automobile, which is an urgent problem to be solved in the new energy automobile industry.

The rocket is started by the karussa rocket gun barrel, the rocket can explode when being launched, but the gun body and the vehicle body are intact.
The technical scheme provided by the invention is as follows:
firstly, the battery pack of the electric automobile is arranged in an exhaust pipe to prevent the battery from burning and exploding to ignite the automobile body. And a battery pack is arranged in an exhaust pipe hoisted under the automobile chassis. A ventilation gap is reserved between the exhaust pipe and the automobile chassis for heat dissipation and high temperature isolation; only towards the opening of the exhaust pipe orifice behind the vehicle, when the battery burns, the flame is discharged from the exhaust pipe tail nozzle, so that the vehicle body is prevented from being ignited.
And secondly, the battery pack is divided into a plurality of battery packs, and each battery pack is packaged in a high-temperature-resistant metal tube. One end of the metal pipe is blocked, and the other end of the metal pipe is opened to be used as a tail nozzle for discharging and spraying flame. The exhaust pipe and the exhaust pipe are arranged at intervals, and the interval gap is used for ventilation and heat dissipation.
The exhaust pipe is made into a U shape by a pipe bending pipe, and pipe orifices at two ends face the rear of the vehicle to form a tail nozzle; the U-shaped elbow faces the front of the vehicle, and the wind resistance coefficient is low; the middle gap of the U-shaped bend is favorable for ventilation and heat dissipation.
And fourthly, the exhaust pipe and the exhaust pipe are made of steel materials and can resist high temperature of about 1500 ℃. Further, the exhaust pipe fixing member is made of an aluminum alloy, which can withstand only a low temperature of about 600 degrees. When the battery burns, the aluminum alloy member is quickly fused, and the exhaust pipe is detached from the vehicle body.
The aluminum alloy hook piece is not limited in structural form, and only when the battery burns, the fastener fails. Under the action of the swing hook, the exhaust pipe swings downwards and backwards, and the tail nozzle is far away from the vehicle body.

The permanent magnet locking mode has the advantages that the exhaust pipe can be detached only under the action of a special equipment tool, the replacement and the maintenance are convenient, and the anti-theft effect is achieved. The permanent magnet is arranged at the pipe orifice of the exhaust pipe, when the magnetic force of the permanent magnet disappears due to the high temperature generated by the combustion of the battery, the fastener fails, and the exhaust pipe swings away from the vehicle body.
The mouth of the exhaust pipe is provided with a fuel breaker, when the fuel breaker is disconnected by high temperature generated by the combustion of the battery, a plurality of fasteners of the exhaust pipe are controlled to fail, and the fuel breaker is an aluminum alloy member or a permanent magnet.
The automobile body does not contain a battery pack and an exhaust pipe, and needs protection and combustion prevention. The battery pack refers to a combustible component mounted outside a vehicle body. The exhaust pipe is arranged outside the vehicle body by using a pendulum hook and a fastener and is used for preventing and isolating a battery from burning.
The exhaust pipe mouth sets up the display for show group battery performance, can also replace the tail lamp, as driving scintillation warning tail lamp, make electric automobile like F1 cycle racing, one row of tail lamp promotes the sensation of moving, increases pleasing to the eye degree.
The wire of the battery pack connected with the vehicle body is an aluminum wire, when the battery burns to generate high temperature above 700 ℃, the aluminum wire can be fused, and the exhaust pipe swings away from the vehicle body.
The exhaust pipes are like piano keys, and each exhaust pipe is independently suspended; when any group of batteries burns, the exhaust pipe is separated from the vehicle body and is separated from the intact battery pack, so that the combustion of one group of batteries and the total battery pack are effectively avoided.
The application of the swing hook of the vehicle body chassis can ensure that the exhaust pipe swings away from the vehicle body when a battery burns, and further avoid the illegal throwing on the expressway.
The temperature difference resistance of the steel pipe and the aluminum alloy, and the temperature difference resistance of the two metal materials can reach 900 ℃, so that the description is convenient, and 700 ℃ is assumed to be set as a critical point; that is, above 700 degrees, the fastener made of aluminum alloy melts, the aluminum wire melts; and the exhaust pipe and the swing hook made of steel are not fused at the temperature of 700 DEG and 1500 ℃.
