Description

Electric automobile

[technical field]

The utility model relates to a kind of electric automobile, particularly electronic bus.

[background technology]

Along with reducing day by day with the pollution of environment of petroleum resources is day by day serious, the protection environment, energy-saving and emission-reduction have become present trend and trend in the world.Under this background, in recent years, be that the electric vehicle of major impetus source or partial power source (mainly comprises PHEV with the battery; The plug-in hybrid car; Engender and increasing that pure electric vehicle) the carbon emission amount of electric vehicle is less than the traditional combustion engine automobile, the carbon emission of pure electric vehicle even be zero; And have the high characteristics of energy conversion efficiency, this makes people electric automobile is regarded as an important selection of following replace internal combustion engines car.

In electric automobile, electronic bus is an important developing direction.Because car body weight is big, the seating capacity is many, and the general storage of the electrokinetic cell bag of electronic bus (particularly pure electronic bus) is bigger, usually more than 100kWh.And corresponding, the battery cell number in the power brick is generally also more than several thousand.So huge energy and more occupant's number make that security has just become the problem that at first will consider for the development of electronic bus.

In present electric automobile, use lithium ion battery as power source usually, lithium ion battery is owing to the character of himself, and it is overheated to tend to occur, on fire.And the burning that in process on fire, is accompanied by electrolyte can discharge a large amount of smog; How when the battery generation is on fire, to suppress smog; Reducing smog to influence and scaring that the passenger breathes, is a major issue that is faced in the electric automobile design, still; Up to now, the perfect technical scheme of Shang Weiyou solves this problem.

[utility model content]

The content of the utility model promptly is to the problems referred to above, and a kind of electric automobile is provided, and when battery takes place can suppress smog rapidly when on fire, and reduces the influence of smog to the passenger as much as possible.

In order to achieve the above object, the utility model comprises: car body, vehicle control device; At least one battery flat body includes a plurality of battery cells in the described battery flat body, and described electric automobile also comprises flue and fire extinguishing cabin; In described fire extinguishing cabin, comprise at least one fire extinguisher by vehicle control device control; In described battery flat body, be provided with at least one Smoke Sensor and at least one temperature sensor, described Smoke Sensor and temperature sensor and vehicle control device be electric connection mutually, and described flue afterbody extends car body and is connected with atmosphere; Described fire extinguishing cabin, flue and each battery flat body are communicated with successively.

As preferred embodiment a kind of, in described fire extinguishing cabin, be provided with fan or compressed air cylinder.

As another preferred embodiment, between flue and each battery flat, be provided with check valve.

As another preferred embodiment, described fire extinguisher is a carbon dioxide extinguisher.

As another preferred embodiment, nitrogen or inert gas are housed in the described compressed air cylinder.

As another preferred embodiment, described battery flat body, flue and fire extinguishing cabin are arranged on the bottom of said electric automobile and isolated with the vehicle upper at passenger place.

Owing to adopted above-mentioned technical scheme; When the smog in certain battery flat or temperature sensor measurement behind temperature signal or smoke signal; Just send signal to vehicle control device; Fire extinguisher in the vehicle control device control fire extinguishing cabin discharges extinguishing material, and extinguishing material gets into the battery flat body through flue, and the smog that produces in the battery flat body can be discharged in the air through the flue afterbody.Can suppress smog so rapidly and, avoid the influence of smog the passenger rapidly with outside the smog discharge car that produces.

[specific embodiment]

Come the utility model is done specific descriptions below in conjunction with accompanying drawing.

Fig. 1 is the car load schematic top plan view among the embodiment, and in the present embodiment, car load comprises car body 1, and branch is distributed in two fire extinguishing cabins 3 of car body 1 both sides at six battery flat bodies 2 of car body 1 both sides, is distributed in two flues 4 of car body 1 both sides.Each fire extinguishing cabin 3 is connected with a

flue

4 and 3 battery flat bodies 2.The afterbody of flue 4 extends the rear portion of car body 1.

Fig. 2 looks sketch map for the car load left side among the embodiment, can find out, in the present embodiment; Fire extinguishing cabin 3; Battery flat body 2 and flue 4 all are arranged on the downside of car body 1, and are separated by with the occupant space on top and leave, like this; Even battery has taken place on fire, also can the influence to the occupant on fire be reduced to minimum.

Fig. 5 is the schematic internal view in fire extinguishing cabin 3 among the embodiment, and in the present embodiment, fire extinguishing is provided with fan 32 and two carbon dioxide extinguishers 31 in the cabin 3; When needs are put out a fire; Fire extinguisher 31 ejection carbon dioxide gas stream, fan 32 starts simultaneously, makes carbon dioxide gas stream flow fast along flue.Can certainly fan 32 be changed to compressed air cylinder and in jar stored nitrogen or inert gas, also can reach same effect.

Fig. 3 is the schematic internal view of battery flat body 2 among the embodiment, and Fig. 3 representes is the sketch map when check valve 23 is closed, and a plurality of battery cells 24 is arranged in the battery flat body 2, and be provided with a plurality of Smoke Sensors 21 and temperature sensor 22.

Fig. 4 is the schematic internal view of battery flat body 2 among the embodiment, and Fig. 4 representes is the sketch map when check valve 23 is opened.

Check valve 23 among Fig. 3 and Fig. 4 adopts spring to be arranged on the axle of check valve, reaches the effect of unidirectional switching, can certainly adopt some other means commonly used that check valve is set.

If certain battery cell 24 in certain battery flat 2 takes place on fire; After the smoke detector in this battery flat 21 or temperature sensor 22 detect signal; Signal on fire is sent to vehicle control device; Fire extinguisher 31 in the vehicle control device control fire extinguishing cabin 3 starts with fan 32 simultaneously, and carbon dioxide gas stream flows along flue 4 beginnings fast.See Fig. 4, at this moment, because air pressure increases, and internal gas flow and smog are pushed check valve 23 open, make smog flow out the battery flat body in the battery flat 24 on fire, flow out vehicle rear fast along flue.Simultaneously, the carbon dioxide gas stream that flows out in the fire extinguishing cabin 3 also flows to battery flat 24, reaches the effect of fire extinguishing.

And for all the other normal battery flats 24, see Fig. 3 this moment, and check valve 23 is in closed condition, and smog and carbon dioxide can not flow in these normal battery flats 24, and these battery flats still can keep normal condition.

The protection domain of the utility model is not limited in embodiment, and all variation and changes of under the utility model spirit, being done all should drop within the utility model protection domain.
