Description
Technical field
The invention belongs to battery pack structure technical field, be specifically related to a kind of water-tight device of novel electric vehicle power brick.
Background technology
Power brick is the power source of electric automobile, and its inside includes multiple battery pack, BSM controller, relay, shunt, fuse, connection copper bar and wire etc.Apparent: except battery is with electrical component exactly inside (1) power brick; Once there be water to enter, will occur: electric short circuit, component damage, even generation battery explosion are caught fire, and cause the serious accident of car crash.(2) effectively solving power brick and enter water problem, is current key subject anxious to be resolved.
Current power brick water-tight device, the single-stage seal form of many employings square-section, because the overall dimensions of power brick is larger, the sealing surface of casing, case lid has larger buckling deformation unavoidably, so adopt the water-tight device of rubber strip of single-stage square-section, entering of the rainwater rolled by wheel when injection water and vehicle travel when effectively can not prevent carwash.
Summary of the invention
For prior art Problems existing, the object of the invention is to design the technical scheme of the water-tight device that a kind of novel electric vehicle power brick is provided.
The water-tight device of described a kind of novel electric vehicle power brick, comprise power brick casing, case lid and the rubber seal be arranged between power brick casing and case lid, it is characterized in that described rubber seal comprises rubbery sealed body and is arranged on the U-shaped skeleton in rubbery sealed body, described rubbery sealed body comprises the 4th sealing be arranged between U-shaped skeleton and case lid end face, be arranged on the first side seals between U-shaped skeleton and case lid medial surface, be arranged on the second side seals between U-shaped skeleton and power brick casing lateral surface and be arranged on the 3rd side seals between U-shaped skeleton and power brick box inside face.
The water-tight device of described a kind of novel electric vehicle power brick, is characterized in that the first described side seals, the second side seals, the 3rd side seals and the 4th sealing are formed in one structure.
The water-tight device of described a kind of novel electric vehicle power brick, it is characterized in that the first described side seals is about one group parallel and downward-sloping sealing strip, the first described side seals outboard end and case lid medial surface offset.
The water-tight device of described a kind of novel electric vehicle power brick, it is characterized in that the second described side seals is about one group parallel and acclivitous sealing strip, the second described side seals outboard end and power brick casing lateral surface offset.
The water-tight device of described a kind of novel electric vehicle power brick, it is characterized in that the 3rd described side seals is arc sealing strip, the 3rd described side seals outboard end and power brick box inside face offset.
The water-tight device of described a kind of novel electric vehicle power brick, is characterized in that the 4th described sealing is hollow sealing strip.
The water-tight device of described a kind of novel electric vehicle power brick, is characterized in that described case lid end face arranges ripple struction.
The water-tight device of above-mentioned a kind of novel electric vehicle power brick, structure is simple, reasonable in design, the structure that above have employed and side seals simultaneously, changes currently to only have the structure sealed above, compared with prior art has following beneficial effect:
1) the 4th sealing is set between power brick casing and case lid, 4th sealing adopts hollow sealing strip, there is larger compressible amount, can solve because power brick casing, case lid have larger buckling deformation completely, simple rectangular section rubber strip owing to measuring restriction by compression, and cannot realize a difficult problem for sealing;
2) first and second and three sealings are set between power brick casing and the side of case lid, form three road labyrinth seal structures, there is high sealing reliability;
3) case lid end face arranges ripple struction, and good rigidity, buckling deformation are little.
Described on end, above the present invention, take hollow sealing structure, be particularly suitable for, to the sealing had compared with wide arc gap or the gap installed surface such as not, solving the insurmountable technical barrier of the solid adhesive tape of traditional rectangular; Set up again three road labyrinth seal structures in side especially, added sealing above, in the water-tight device of this power brick, be provided with the four road precautionary measures altogether, this be front institute before institute not, unusual innovative design.Think through expert: power brick water-tight device of the present invention, really belong to structure original creation, the rainwater rolled by wheel when injection water and vehicle travel when really effectively can prevent carwash, to the intrusion of power brick, has perfect sealing usefulness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-case lid; 101-ripple struction; 2-rubber seal; 201-the 4th sealing; 202-U shape skeleton; 203-first side seals; 204-second side seals; 205-the 3rd side seals; 3-bolt; 4-power brick casing.
Embodiment
The present invention is further illustrated below in conjunction with Figure of description.
As shown in the figure, a kind of water-tight device of novel electric vehicle power brick comprises case lid 1, rubber seal 2, bolt 3 and power brick casing 4.Case lid 1 and power brick casing 4 are fixed by bolt 3.Rubber seal 2 is arranged between power brick casing 4 and case lid 1, plays sealing function.Rubber seal 2 comprises rubbery sealed body and is arranged on the U-shaped skeleton 202 in rubbery sealed body.Rubber seal 2 comprises the first side seals 203, second side seals 204, the 3rd side seals 205 and the 4th sealing 201.First side seals 203, second side seals 204, the 3rd side seals 205 and the 4th sealing 201 are formed in one structure.Wherein the first side seals 203 is arranged between U-shaped skeleton 202 and case lid 1 medial surface, and the first side seals 203 is about one group parallel and downward-sloping sealing strip, and the first side seals 203 outboard end props up mutually with case lid 1 medial surface.Second side seals 204 is arranged between U-shaped skeleton 202 and power brick casing 4 lateral surface, and the second side seals 204 is about one group parallel and acclivitous sealing strip, and the second side seals 204 outboard end props up mutually with power brick casing 4 lateral surface.3rd side seals 205 is arranged between U-shaped skeleton 202 and power brick casing 4 medial surface, and the 3rd side seals 205 is arc sealing strip, and the 3rd side seals 205 outboard end and power brick casing 4 medial surface offset.4th sealing 201 is arranged between U-shaped skeleton 202 and case lid 1 end face, and the 4th sealing 201 is hollow sealing strip.In order to ensure the rigidity of case lid 1, ripple struction 101 is set at case lid 1 end face.
