Technical field
The utility model relates to lithium ion power automobile batteries sealing device field, in particular to a kind of lithium ions
The waterproof sealing structure of power vehicle battery sheet metal box body.
Background technique
With the development of electric car industry, the safety of electric automobile power battery system is concerned.Currently, power
Battery modules after case lid is simply fastened with cabinet, are connected in sheet metal box body by bolt with the intracorporal nut of case to realize
Sealing；Such sealing means cause not shutting at the assembling of case lid and cabinet, and water is easy to enter cabinet from side, and bolt passes through
The intracorporal nut connection of Kong Houyu case on case lid, water are easy to penetrate into cabinet from bolt, influence electrokinetic cell system electricity consumption
Safety, threatens the life of people.
Utility model content
Purpose of the utility model is to solve above-mentioned existing defect, provide that a kind of structure is simple, can effectively mention
Rise the anti-watertight of the lithium ion power automobile batteries sheet metal box body of the waterproof seal of lithium ion power automobile batteries sheet metal box body
Seal structure.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of waterproof sealing structure of lithium ion power automobile batteries sheet metal box body, including cabinet and be fastened on cabinet
Case lid, it is characterised in that: the both ends of the case lid are equipped with outwardly extending first extended segment, the cabinet on the outside of cabinet
Outside be equipped with the second extended segment for locking with the first extended segment, pass through between first extended segment and the second extended segment
Check bolt wears locking, the Anti-slip nut cooperated with check bolt is equipped in the lower end of the check bolt, described first prolongs
It stretches and is equipped with elastic filler in the cavity between section and the second extended segment, the contact jaw two sides of the check bolt and cavity are all provided with
There is 1 limited block.
The upper end of the limited block is fixedly connected with the inner wall of the first extended segment as a preferred technical solution, under
End extends to the end of the second extended segment along outside.
The elastic filler is polyurethane foam material or nylon plastic(s) or polyethylene bubble as a preferred technical solution,
Foam plastics.
2 are equipped between the check bolt and the contact jaw of the outer end face of the first extended segment as a preferred technical solution,
A lock washer.
The utility model has the following beneficial effects: waterproof construction is simple, manufacture difficulty is low, passes through the elastic filler in cavity
And limited block can reduce the gap between case lid and cabinet to the maximum extent, prevent the liquid outside cabinet from passing through case lid and cabinet
Between gap enter in cabinet, effectively increase the waterproofing grade of sheet metal box body.
Detailed description of the invention
Fig. 1 is a kind of structural representation of the waterproof sealing structure of lithium ion power automobile batteries sheet metal box body of the utility model
Figure.
In figure: 1- cabinet, 2- case lid, the first extended segment 3-, the second extended segment 4-, 5- check bolt, 6- Anti-slip nut, 7-
Elastic filler, 8- limited block, 9- lock washer.
Specific embodiment
To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with
Good examples and drawings cooperate detailed description, are described as follows:
As shown in Figure 1, a kind of waterproof sealing structure of lithium ion power automobile batteries sheet metal box body, including cabinet 1 and
The case lid 2 being fastened on cabinet 1, the both ends of case lid 2 are equipped with along 1 outwardly extending first extended segment 3 in outside of cabinet, cabinet 1
Outside be equipped with the second extended segment 4 for locking with the first extended segment 3, pass through between the first extended segment 3 and the second extended segment 4
Check bolt 5 wears locking, and the Anti-slip nut 6 cooperated with check bolt 5, the first extended segment 3 are equipped in the lower end of check bolt 5
Elastic filler 7 is equipped in cavity between the second extended segment 4, check bolt 5 and the contact jaw two sides of cavity are equipped with 1
Limited block 8.
In the present embodiment, the upper end of limited block 8 is fixedly connected with the inner wall of the first extended segment 3, and lower end extends to
The end of two extended segments 4 is along outside.
In the present embodiment, elastic filler 7 is polyurethane foam material or nylon plastic(s) or polyethylene foams.
In the present embodiment, 2 lock pads are equipped between check bolt 5 and the contact jaw of the outer end face of the first extended segment 3
Circle 9.
In the present embodiment, check bolt 5 passes through Anti-slip nut 6 after successively wearing the first extended segment 3 and the second extended segment 4
The end of locking, the lower end of limited block 8 and the second extended segment 4 has certain difference in height along outside, and the upper end of Anti-slip nut 6 is being pushed up
It is best locking state when to the lower end of limited block 8, waterproof construction is simple, and manufacture difficulty is low, can reduce case lid 2 to the maximum extent
With the gap between cabinet 1, prevent the liquid outside cabinet 1 from entering in cabinet 1 by the gap between case lid 2 and cabinet 1,
Effectively increase the waterproofing grade of sheet metal box body.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
