Abstract
The utility model provides a waterproof and dustproof structure for a battery pack of an electromobile. The waterproof and dustproof structure comprises an upper box and a lower box, wherein the upper box is provided with a first connection part; the lower box is provided with a second connection part; the first connection part and the second connection part are connected by bolts; a skirt-like structure extends downwards from the outer edge of the first connection part to surround the edge of the second connection part; and a sealing adhesive is coated between the upper box and the lower box, so that the upper box and the lower box are sealed. According to the waterproof and dustproof structure, the skirt-like structure of the upper box of the battery pack is added, and the sealing adhesive is coated to seal the upper and lower boxes, so that dust and water can be effectively prevented from entering the battery pack through a gap at the joint of the boxes of the battery pack, and the waterproof and dustproof performance of the battery pack is improved.
Description
[technical field]
The utility model relates to a kind of power brick waterproof and dustproof structure of electric automobile.
[background technology]
The power brick of electric automobile is that electric motor car drives and other high pressure power consumption equipments provide energy source; Because power brick high voltage, high-octane characteristic; Improper use is easy to generate danger; Therefore environment for use is required must carry out the safeguard measure of power brick than higher, to improve the useful life of battery.In the time of the battery immersion, be easy to generate short circuit, blast, so must improve the classification of waterproof of power brick; The power brick internal electronic component is more, advances under the situation of ash, causes electronic component failure easily, must improve dustproof grade.
The shell body of the power brick of electric automobile is generally the last lower box that metal sheet is processed into given shape at present, is integrally formed the power brick of formula again with bolt.The last lower box of power brick generally is that concordant installation connects, though between last lower box, increased fluid sealant, but be easy to generate the slit, cause the dustproof and waterproof grade to reduce.
[summary of the invention]
The technical problem that the utility model will solve; Be to provide a kind of power brick waterproof and dustproof structure of electric automobile; Utilize the shirt rim structural design of the increase of power brick casing; Effectively blocks dust and water get into power brick inside through the slit of power brick casing junction, thereby improve the water proof and dust proof ability of power brick.
The utility model is achieved in that a kind of power brick waterproof and dustproof structure of electric automobile; Comprise upper box and lower box; Upper box has first connecting portion, and lower box has second connecting portion, and said first connecting portion is connected with bolt with second connecting portion; Wherein: the outer of said first connecting portion is to extending below a shirt rim structure surrounding the edge of second connecting portion, and scribbles fluid sealant between upper box and the lower box and seal.
Said fluid sealant is coated in the junction of said first connecting portion and second connecting portion, and is coated between the edge of inboard and second connecting portion of said shirt rim structure.
The advantage of the utility model is: the waterproof and dustproof structure of the utility model; Utilize the shirt rim structural design of the increase of power brick casing; Being aided with fluid sealant again seals; Blocks dust and water get into power brick inside through the slit of power brick casing junction effectively, thereby improve the water proof and dust proof ability of power brick.
[description of drawings]
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the perspective view of the power brick waterproof and dustproof structure of the utility model.
Fig. 2 is the sectional structure sketch map of the power brick waterproof and dustproof structure of the utility model.
[embodiment]
See also illustrated in figures 1 and 2; The power brick waterproof and dustproof structure of the utility model electric automobile; Comprise upper box 1 and lower box 2, upper box 1 has first connecting portion 11, and lower box 2 has second connecting portion 22; Be equipped with screw 3 on said first connecting portion 11 and second connecting portion 22; Available bolt (not shown) connects, and the outer of said first connecting portion 11 is to extending below a shirt rim structure 12 surrounding the edge of second connecting portion 22, and scribbles fluid sealant 4 between upper box 1 and the lower box 2 and seal.
Specifically be, said fluid sealant 4 is coated in the junction 41 of said first connecting portion 11 and second connecting portion 22, and is coated between the edge of inboard and second connecting portion 22 of said shirt rim structure 12 42.
As previously mentioned; The waterproof and dustproof structure of the utility model utilizes the shirt rim structural design of the increase of power brick casing, is aided with fluid sealant again and seals; Blocks dust and water get into power brick inside through the slit of power brick casing junction effectively, thereby improve the water proof and dust proof ability of power brick.
Though more than described the embodiment of the utility model; But the technical staff who is familiar with the present technique field is to be understood that; We described concrete embodiment is illustrative; Rather than being used for qualification to the scope of the utility model, those of ordinary skill in the art are in the modification and the variation of the equivalence of doing according to the spirit of the utility model, all should be encompassed in the scope that the claim of the utility model protects.
