Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
The utility model provides a kind of detachable combination seal.The combination seal is preferably provided at low-speed vehicle
With on lesser battery, for example, maintenance off-line regeneration can be carried out to battery in glove box or drying room.
As shown in Figure 1, the combination seal can be sealed the note round 2 being formed on battery cover board 1.Infuse round
2 can be the stepped hole for being used to inject electrolyte on existing battery cover board.In this way, combination seal may be directly applied to now
Some battery cover boards do not need to be modified the shoulder hole structure on existing battery cover board, easy to use, versatile.
As shown in Figure 2-5, combination seal include resilient plug 3 and rigidity nail 4, resilient plug 3 can with note round 2 match and
It is formed with mounting hole 31.Rigidity nail 4 can be packed into mounting hole 31 and by the outer surface of resilient plug 3 and note round 2 inner surface pressure
Close envelope.Preferably, resilient plug 3 and rigidity nail 4 can be fabricated to matching used standard component, wherein resilient plug 3 is destructiveness
Sealing element, it is not possible to it repeatedly uses, and rigidity is followed closely 4 and be may be reused.In this way, battery fluid infusion or change liquid regeneration after, use
New resilient plug 3 and rigidity nail 4 before are sealed.
As shown in figure 5, resilient plug 3 can be designed to T-shaped structure, inside is formed with to accommodate the blind hole of rigidity nail 4.Bullet
The tail portion of property plug 3 is formed with flange 32.The head of resilient plug 3 is formed as frustum 33 tapered in assembly direction.When installation, frustum
33 can play guiding function, and after being installed, flange 32 can be embedded in note round 2 and be clamped with macropore, play positioning action.
Since mounting hole 31 is blind hole, after rigidly nail 4 is packed into resilient plug 3, rigidity can also be avoided to follow closely 4 and directly contacted with electrolyte.
The structure of note round 2 will not be damaged in order to guarantee combination seal in installation and removal, the material of resilient plug 3 is excellent
It is selected as the preferable elastic material of toughness.In this way, resilient plug 3 will receive after resilient plug 3 and rigidity nail 4 are sequentially loaded into note round 2
Rigidity follows closely 4 extruding and deformation occurs to be formed and be sealed between note round.
Electrolyte causes etch to combination seal in order to prevent, and the material of resilient plug 3 is preferably the material of electrolyte resistance.
As shown in fig. 6, rigidity nail 4 head be formed with for by the outer surface of resilient plug 3 and note round 2 inner surface pressure
Tight ball-crown body 41 or reversed acanthoid structure (not shown).The size of ball-crown body 41 or reversed acanthoid structure is slightly larger than the ruler of blind hole internal diameter
It is very little.It should be noted that the head of rigidity nail 4 may be formed as other shapes, make as long as extruding can be played to resilient plug 3
With, enable infuse 2 sealing of round.
For the ease of the assembly and disassembly of rigidity nail 4 and resilient plug 3, the tail portion of rigidity nail 4 is formed to and flange 32
Inner surface match extend out formula cone 42.When sealing, resilient plug 3 is first pressed into note round 2, so that the lower surface of flange 32
With the ladder face contact of note round 2.Later, rigidity nail 4 is inserted into the blind hole of resilient plug 3, until extending out the outer of formula cone 42
Surface and the inner surface of flange 32 fit closely, and the ball-crown body 41 of rigidity nail 4 compresses the side wall of resilient plug 3 just at this time, with note
The inner wall of round 2 forms sealing.The upper surface of resilient plug 3 and rigidity nail 4 in the same plane, and is higher than the outer of battery cover board 1
Surface.When changing liquid, first it is pulled out with the tail portion that specific purpose tool clamps rigidity nail 4 in glove box or drying room, so that elastic
Plug 3 loses extruding, and then resilient plug 3 is extracted.
It should be noted that, although the note round in the utility model is the explanation carried out by taking existing stepped hole as an example, but
It is that the note round in the utility model can also be the hole of other shapes, and the combination seal of the utility model may be it
The combination seal of his shape, as long as can be realized matching, sealing each other.
The utility model additionally provides a kind of battery cover board, and note round is provided on battery cover board, and note round passes through above-mentioned
Combination seal be sealed.Preferably, note round is arranged in pairs and at least two.In this way, when one of note round
When for vacuumizing, another note round can be used for fluid injection.Therefore, it can reduce battery case by the way that two note rounds are arranged
The pressure difference being subject to, and then reduce and change liquid damage caused by battery, liquid efficiency is changed in promotion.
In addition, battery cover board can may be the cover board of cylindrical battery for the cover board of rectangular cell.
Finally, the utility model additionally provides a kind of lithium slurry battery, which includes battery case 11 and electricity
The battery core that pond shell 11 is fitted together to form the battery cover board 1 of closed chamber and be arranged in battery case 11.Battery core packet
Include positive plate/diaphragm/negative electrode tab of multiple alternately laminated settings, wherein be provided with note round 2 on battery cover board 1, infuse round 2
It is sealed by combinations of the above sealing element.When needing to carry out lithium slurry battery maintenance regeneration, can in glove box or
The combination seal on lithium slurry battery cover board is dismantled in drying room, round opening will be infused.Later, it is set using maintenance regeneration
Maintenance off-line regeneration is completed in the standby operation that replacement electrolyte is carried out to lithium slurry battery.
Although the present utility model has been described by reference to the preferred embodiments, but in the model for not departing from the utility model
In the case where enclosing, various improvement can be carried out to it and can replace component therein with equivalent.Especially, as long as not depositing
In structural conflict, items technical characteristic mentioned in the various embodiments be can be combined in any way.The utility model
It is not limited to specific embodiment disclosed herein, but is included all technical solutions falling within the scope of the claims.
