Abstract
The utility model discloses a dedicated split style upper spacer for a lithium-ion power battery capable of being recycled and automatically assembled. In the dedicated split style upper spacer for the lithium-ion power battery, an upper split body and a lower split body are mutually connected through snap buttons, the snap buttons are respectively fixed in the middle inside the upper split body and the lower split body, air bleeder containing holes are formed between the snap buttons, pole column lug containing holes are formed at two sides of the air bleeder containing holes, and an electrolyte injection trough is respectively arranged at the opposite angles of the upper split body and the lower split body. The dedicated split style upper spacer has a simple structure, not only can an insulation positioning function be ensured, but also injection molding and machining can be convenient. The dedicated split style upper spacer can be recycled, therefore, production cost is reduced, an assembly technology can be optimized, and the upper spacer is applicable to large-scale industrialization production.
Description
Technical field
The utility model relates to a kind of electrokinetic cell Upper gasket structure, the square electrokinetic cell Upper gasket of especially a kind of lithium ion structure.
Background technology
Along with the development of lithium ion battery industry, the progressively intensification of especially electric motor car industry, the application of power lithium-ion battery also more and more widely, the thing followed is the concerns of people to lithium ion battery performance, large-scale production and fail safe.Rectangular lithium ion electrokinetic cell Upper gasket can keep utmost point group stability of structure in the battery effectively, can prevent effectively that battery and housing are short-circuited simultaneously.
Generally all be the integrated through injection molding structure for existing electrokinetic cell Upper gasket, before the welding of battery utmost point group and battery lid, adopt the hand assembled mode, cause pad to reuse and can not realize that automation assembles as follow-up appearance is bad.
The utility model content
The purpose of the utility model is in order to overcome the defective of above-mentioned prior art, but a kind of special-purpose split type Upper gasket of lithium-ion-power cell that reuses the automation assembling is provided.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
The special-purpose split type Upper gasket of lithium-ion-power cell; Said Upper gasket is interconnected through double buckle by last split and following split; Double buckle is individually fixed in split and following split middle inside; Form the vent valve accommodation hole between the said double buckle, vent valve accommodation hole both sides form pole lug accommodation hole, and the place, diagonal angle of last split and following split is provided with electrolyte respectively and injects groove.
The utility model structure has following beneficial effect:
1, above-mentioned split type Upper gasket is simple in structure is convenient to injection moulding processing when can guarantee to insulate positioning action again.
2, split-type structural can use flexibly, not only can be in battery utmost point group with use before the battery lid is connected but also can be connected the back with the battery lid in utmost point group and use.
3, can reuse and reduce production costs, optimize assembly technology, be fit to large-scale industrial production.
Description of drawings
Fig. 1 is the split sketch map of the utility model;
Fig. 2 is the combination sketch map of the utility model.
Embodiment
For further specifying the utility model, conjunction with figs. is set forth in detail:
Like Fig. 1, shown in Figure 2; The utility model Upper gasket is interconnected through double buckle 3 with following split 2 by last split 1; Double buckle is individually fixed in split and following split middle inside, forms vent valve accommodation hole 4 between the said double buckle, and vent valve accommodation hole both sides form pole lug accommodation hole 5; The place, diagonal angle of last split and following split is provided with electrolyte respectively and injects groove 6; So it is that the electrolyte of being close to can get into inside batteries through injecting groove 6 because of battery cover and Upper gasket that electrolyte injects groove 6, Upper gasket interconnects the steadiness of assurance pad through double buckle 3, plays the effect of stable cell.Last split 1 is connected the back and forms vent valve accommodation hole 4 with following split 2;, inside battery air pressure can rapidly gas be discharged when increasing through vent valve accommodation hole 4; Guaranteed the security performance of battery; Last split 1 with also form pole lug accommodation hole 5 simultaneously after following split 2 is connected, have enough waiting to put the space after making lug and pole being connected and guarantee that lug contact the raising security performance with the battery shell wall.
The two parts dismounting of the utility model Upper gasket are simple and easy, all can use before and after being connected with battery cover in battery utmost point group, follow-uply the bad also detachable recycling of getting off of battery, the production of the modern automation of being more convenient for Robot actions occur.
The above only is the preferred implementation method of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
