Abstract
The utility model belongs to power battery technology field, more particularly to a kind of electrokinetic cell top cover sealing ring, including the first annular seal body, and from the axial end of the first annular seal body raised vertically the second annular seal body, and the internal diameter of the second annular seal body is more than the internal diameter of the first annular seal body.Compared to prior art, the utility model solves the problem of low existing electrokinetic cell top cover sealing ring air-tightness, easy gas leakage, effectively increases the sealing effectiveness of sealing ring by the way that sealing ring is arranged into double containment body structure.
Description
Technical field
The utility model belongs to power battery technology field, more particularly to a kind of electrokinetic cell top cover sealing ring.
Background technology
The cap structure of electrokinetic cell generally uses riveted structure or clip spring structure, but either riveting knot in the market
Structure or clip spring structure, are required for being sealed with sealing ring between coping plate and the pole for wearing coping plate, thus sealing ring
Sealing property seem particularly critical.In the prior art, the structure of sealing ring is as shown in figure 1, it includes annular base 1 ' and ring
The projection 2 ' set around the inner circumferential of annular base 1 ', the L-shaped structure of its radial section.But the structure of this sealing ring is simple
Single, it can only form single sealing surface with pole, and air-tightness is relatively low, extremely easy to leak when being set on pole
The situation of gas, so as to influence the security performance of battery.
Utility model content
The purpose of this utility model is：For the existing electrokinetic cell top cover low deficiency of sealing ring air-tightness, and carry
For a kind of air-tightness is good and the excellent electrokinetic cell top cover sealing ring of sealing effectiveness.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of electrokinetic cell top cover sealing ring, including the first annular seal body, and from the first annular seal body
Axial end on raised vertically the second annular seal body, and the internal diameter of the second annular seal body is more than described first
The internal diameter of annular seal body.
Improved as one kind of the utility model electrokinetic cell top cover sealing ring, the radial section of the sealing ring is in
"convex" shaped structure.
Improved as one kind of the utility model electrokinetic cell top cover sealing ring, the internal diameter of the first annular seal body
Size is 1~50mm, preferably 5~15mm；If internal diameter is too small, the conveyance capacity of pole can be influenceed.
Improved as one kind of the utility model electrokinetic cell top cover sealing ring, the internal diameter of the second annular seal body
Size is 1.5~55mm, preferably 10~20mm；If internal diameter is too small, the conveyance capacity of pole can be influenceed.
Improved as one kind of the utility model electrokinetic cell top cover sealing ring, the thickness of the first annular seal body
More than or equal to 0.5mm；If thickness is too small, the shock-absorbing capacity that sealing ring can be influenceed overall.
Improved as one kind of the utility model electrokinetic cell top cover sealing ring, the thickness of the second annular seal body
More than or equal to 0.3mm；If thickness is too small, the shock-absorbing capacity that sealing ring can be influenceed overall.
The beneficial effects of the utility model are：A kind of electrokinetic cell top cover sealing ring of the utility model, including first
Annular seal body, and raised vertically the second annular seal body from the axial end of the first annular seal body, and
The internal diameter of the second annular seal body is more than the internal diameter of the first annular seal body.Compared to prior art, this practicality is new
Type solves existing electrokinetic cell top cover sealing ring air-tightness low, easy by the way that sealing ring is arranged into double containment body structure
The problem of gas leakage, effectively increase the sealing effectiveness of sealing ring.
Brief description of the drawings
Fig. 1 is the structural representation of sealing ring in the prior art.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the sectional view in Fig. 2 along line A-A.
In figure：1 '-annular base；2 '-convex edge；1- the first annular seal bodies；2- the second annular seal bodies.
Embodiment
With reference to embodiment and Figure of description, the utility model is described in further detail, but this
The embodiment not limited to this of utility model.
As shown in figures 2-3, a kind of electrokinetic cell top cover sealing ring, including the first annular seal body 1, and from first
Second annular seal body 2 raised vertically on the axial end of annular seal body 1, the internal diameter of the second annular seal body 2 is more than
The internal diameter of first annular seal body 1, and the radial section of sealing ring is in "convex" shaped structure；Wherein, sealing ring uses high temperature resistant
Insulating materials of good performance makes, such as fluorubber, silicon rubber, ceramic material.
Compared to existing sealing ring, the utility model is solved existing by the way that sealing ring is arranged into double containment body structure
Dynamic battery cap is with sealing ring air-tightness is low, easy gas leakage the problem of, effectively increase the sealing effectiveness of sealing ring.
In the embodiment according to electrokinetic cell top cover sealing ring of the present utility model, the first annular seal body 1
Internal diameter size is 1~50mm, preferably 5~15mm；If internal diameter is too small, the conveyance capacity of pole can be influenceed.
In the embodiment according to electrokinetic cell top cover sealing ring of the present utility model, the second annular seal body 2
Internal diameter size is 1.5~55mm, preferably 10~20mm；If internal diameter is too small, the conveyance capacity of pole can be influenceed.
In the embodiment according to electrokinetic cell top cover sealing ring of the present utility model, the first annular seal body 1
Thickness is more than or equal to 0.5mm；If thickness is too small, the shock-absorbing capacity that sealing ring can be influenceed overall.
In the embodiment according to electrokinetic cell top cover sealing ring of the present utility model, the second annular seal body 2
Thickness is more than or equal to 0.3mm；If thickness is too small, the shock-absorbing capacity that sealing ring can be influenceed overall.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to above-mentioned embodiment, every this area skill
It is new that art personnel any conspicuously improved, replacement made on the basis of the utility model or modification belong to this practicality
The protection domain of type.Although in addition, having used some specific terms in this specification, these terms are intended merely to convenient say
It is bright, the utility model is not construed as limiting.
