In place of the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, design science,
Use safety, electrokinetic cell can eject when car crass and facilitate dismounting, a kind of electric automobile battery box changed in time
Body protection device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of electric automobile battery box body protection device, including Battery case, fixing shank, controls cylinder, storage device of air,
Described Battery case is fixedly connected with the vehicle body by being arranged at the fixing shank of casing surrounding, and described control cylinder passes through piston rod
Controlling the fixing forward and backward plug of shank, described storage device of air is connected with controlling cylinder rod chamber by storing air pipe, described storage gas
Being provided with the air pressure generator that can produce rapidly a large amount of gas in device, this air pressure generator can make by producing a large amount of gases
Storing device of air generation excess gas pressure by piston rod fight back and makes Battery case come off rapidly.
And, described Battery case and car body joint face rear and front end are additionally provided with catapult-launching gear, and this catapult-launching gear includes
Ejection plate and the stage clip being arranged between ejection plate and Battery case.
And, use chemical substance to ignite in described air pressure generator, and pass to control by colliding sensor
Unit, then ignites ignition signal output.
And, described chemical substance is by the Sodium Azide after extremely compressing and aqueous vapor generated reactive gas.
And, described control cylinder side is additionally provided with relief valve.
And, the air pressure that described relief valve threshold value exports in rod chamber by storing air pipe with storage device of air is identical.
And, being additionally provided with the fixing shank of guarantee between described fixing shank and piston rod will not take off because pneumatic cylinder lost efficacy
The slip-off preventing stage clip fallen.
Advantage of the present utility model and economic effect be:
This utility model uses shank to be combined with electric automobile car body, and is controlled fixing, not only by controlling cylinder
Achieve quick-replaceable set of cells, provide considerable cruise mileage and outstanding charging ability for electric automobile；But also it is logical
Crossing storage device of air to cooperate with air pressure generator, it is achieved when electric automobile collides, colliding sensor can ignite air pressure
Generator, thus by piston rod fight back and Battery case is come off rapidly by the excess gas pressure produced, completely cut off electricity in time
All burning things which may cause a fire disaster of electrical automobile, improve the safety in utilization of electric automobile.
