Abstract
The utility model discloses a kind of battery pack structure of electric automobile, comprise power brick, described power brick is installed in a housing, it is characterized in that: described housing is provided with a wireway, drier and dust screen pack is provided with in described wireway, and described wireway front end is connected with described housing, tail end is air inlet.The utility model, by arranging wireway on housing, ensure that temperature and the pressure of power brick operational environment, improves the operating efficiency of power brick, extend the useful life of power brick.
Description
Technical field
The utility model relates to a kind of electric automobile, is specifically related to a kind of battery pack structure of electric automobile.
Background technology
Along with petroleum resources day by day reduce and the pollution of environment day by day serious, protection of the environment, energy-saving and emission-reduction become current trend in the world and trend.In this context, in recent years, be that the motor vehicle (mainly comprising hybrid electric vehicle, plug-in hybrid electric vehicle, pure electric vehicle) of main power source or partial power source engenders and increasing with battery, the carbon emission amount of motor vehicle is less than traditional combustion engine automobile, the carbon emission amount of pure electric vehicle is even zero, and have the advantages that energy conversion efficiency is high, this makes people electric automobile is considered as the following important selection substituting diesel locomotive.
The power of current electric automobile provides primarily of power brick, and particularly lithium battery bag all needs to be arranged on afterwards in groups in the higher container of requirement of shelter, and current battery is installed in after being bundled into group in closed container to reach requirement of shelter.Power brick inside must be brought like this and define airtight cavity, like this, when being subject to outside heat radiation, or due to battery produce heat in the course of the work time, owing to there is no the flowing of air, enclosed cell bag internal heat is gathered, and causes the operating ambient temperature of power brick own to raise, affects battery life.And gather due to temperature, cause forming high pressure due to high temperature in sealed cell bag, be totally unfavorable to the safety of power brick, there is potential safety hazard.
Summary of the invention
The utility model object is to provide a kind of battery pack structure of electric automobile, by using this structure, improves fail safe when batteries of electric automobile bag uses.
For achieving the above object, the technical solution adopted in the utility model is: a kind of battery pack structure of electric automobile, comprise power brick, described power brick is installed in a housing, described housing is provided with a wireway, be provided with drier and dust screen pack in described wireway, and described wireway front end is connected with described housing, tail end is air inlet.
In technique scheme, described wireway front end is installed on described housing through flange.
In technique scheme, described wireway is coiled pipe, and described dust screen pack is arranged at the air inlet place of described wireway, and described drier is arranged at the middle part of described wireway.
In technique scheme, described dust screen pack is made up of the spunbond polyester non-woven fabric of long fibre.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. on the housing of placing battery bag, wireway is installed in the utility model, make the pressure in housing consistent with the external world, drier and dust screen pack are also set in wireway simultaneously, effectively prevent moisture and dust from entering in power brick, ensure normal use and the useful life of cell panel, compared with the shell structure in the past sealed, the high temperature that in housing, power brick work produces, high pressure can be discharged in time by wireway, make power brick can be in a comparatively suitable operational environment, the limited useful life extending power brick, also improve the operating efficiency of power brick,
2. in the utility model, wireway is coiled pipe, makes extraneous impurity be difficult to enter into housing by coiled pipe, effectively ensure that the operational environment of power brick, extend the useful life of power brick.
Accompanying drawing explanation
Fig. 1 is the structural representation (power brick does not draw) in the utility model embodiment one;
Fig. 2 is the structural representation of wireway in the utility model embodiment one.
Wherein: 1, housing; 2, wireway; 3, flange; 4, drier; 5, dust screen pack.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: shown in Fig. 1,2, a kind of battery pack structure of electric automobile, comprises power brick, and described power brick is installed in a housing 1, described housing 1 is provided with a wireway 2, and described wireway 2 is installed on described housing 1 through flange 3.Be provided with drier 4 and dust screen pack 5 in described wireway 2, and described wireway 2 front end is connected with described housing 1, tail end is air inlet.
In the present embodiment, described wireway 2 is coiled pipe, and described dust screen pack 5 is made up of the spunbond polyester non-woven fabric of long fibre, and described dust screen pack 5 is arranged at the air inlet place of described wireway 2, and described drier 4 is arranged at the middle part of described wireway 2.Dust screen pack 5 is arranged at air inlet, drier 4 is arranged at dust screen pack 6 rear end, can first filter dust, then by drier 4 adsorption moisture, if drier 4 is arranged at air inlet, the rear end that dust screen pack establishes 5 to be placed in drier 4, drier 4 can first attracting dust and moisture, and the effect played of dust screen pack 5 is not just very large, and drier 4 easily block by dust, need frequent replacing, before being therefore arranged on by dust screen pack 5, after drier 4 is arranged on.When power brick works, the temperature of housing 1 inside raises, internal pressure is caused to increase, inner gas is made to flow in extraneous air by wireway 2, when power brick break-off, when temperature declines, inner pressure also reduces thereupon, now extraneous air flows into the inside of housing 1 by the dust screen pack 5 in wireway 2, drier 4, due to the effect of dust screen pack 5 and drier 4, just effectively prevents the dust in extraneous air and moisture to flow into housing 1 inner.When reality uses, when extraneous air enters wireway 2, first by dust screen pack 5 by dust to filtering out, and then removed by moisture by drier 4, dry like this, clean air enters to that housing 1 is interior would not have a negative impact to power brick.Even if dust screen pack 5 can only filter most dust, part dust may be also had to enter to coiled pipe, but because coiled pipe is multiple U-shaped turning pipeline compositions, this part dust also slowly can be deposited in pipeline due to the resistance of U-shaped turning pipeline entering in the middle of this process of housing 1, remaining also can dried dose 4 absorption fall, can't enter in power brick, can not have an impact to power brick, ensure operating efficiency and the useful life of power brick.
