Current lithium ion battery coil core needs encapsulate and bottom to place insulation spacer to prevent that rolling up core contacts and cause short circuit etc. with metal shell before entering shell, and encapsulate and placement insulation spacer need substep operation, can not be integrated, complex process, causes human cost to raise.For this reason, applicant once developed a kind of square lithium ion battery winding core retainer plate (Chinese utility model patent, application number is: 201320166668.4), this square lithium ion battery coil core cover, include volume core retainer plate body, volume core retainer plate body is the cube structure of sealing, on the positive upper surface of volume core retainer plate body, has lug via hole, one side of positive upper surface is rotatably installed on the sidewall of volume core retainer plate body, and positive upper surface can be along opening on one side.
This utility model patent is by integrated existing assembling mode, compare the assembling mode of existing complexity, simplified technique, can enhance productivity, reduce human cost, and integrated structure distortion or the damaged potential safety hazard causing of single part in former assembling mode are avoided.But in practical application, because volume core retainer plate only has upper surface open, volume core must pack volume core retainer plate into from upper end open, and volume core pack into volume core retainer plate when inner very easily with the side plate of volume core retainer plate in wall friction, cause pole piece dry linting; In the time that the material of volume core retainer plate side plate is metal, will causes rolling up core and directly contact and be short-circuited with side plate inwall.
Therefore, those skilled in the art is devoted to develop one and is easy to assembling, and significantly improves pole piece dry linting because occurring in assembling process and the lithium ion battery coil core cover of short circuit.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide integrated existing assembling mode, thereby solve because of the bottom insulation pad safety problem causing that misplaces, and pack volume core into volume the problems such as pole piece dry linting and short circuit do not occur when core retainer plate, thereby enhance productivity and security performance, reduce the lithium ion battery coil core cover of human cost.
For achieving the above object, the utility model provides lithium ion battery coil core cover, formed by least three side plates and a base plate, described side plate lower edge and described bottom edge join, and it is characterized in that: described side plate can spin upside down along described side plate lower edge and the described bottom edge axis forming that joins.
Adopt this technical scheme, make to avoid rubbing with rolling up core retainer plate side plate inwall in the time volume core being packed into volume core retainer plate, thereby solved the technical problem of pole piece dry linting and short circuit.
Preferably, described lithium ion battery coil core cover is square or cuboid.In this embodiment, described side plate is four.But; the shape of lithium ion battery coil core cover is not the emphasis of the utility model protection; no matter adopt which kind of shape; as long as adopted the disclosed side plate of the utility model to do the technical scheme that spins upside down along the join axis that forms of side plate lower edge and bottom edge, all dropped in the claimed scope of the utility model.
Preferably, described side plate and/or base plate are provided with some electrolyte permeability hole.Thereby make electrolyte can permeate volume core retainer plate.
In preferred embodiment of the present utility model, lithium ion battery coil core cover is made up of plastic material.In prior art, the metal materials such as aluminium box, steel box that adopt are made more, have increased volume core and have rolled up the probability that in core retainer plate side plate, wall friction is short-circuited, and after application plastic material, can significantly reduce the possibility that short circuit occurs.
In embodiment of the present utility model, described side plate is after packing volume core into and upwards overturning, and described side plate edge and adjacent side plates edge join between two.
Preferably, the edge of described side plate is sticky mutually with glue.Or:
The edge of described side plate is pasted fixing with adhesive plaster mutually.Or:
The edge of described side plate is respectively provided with a tab, and described tab is mutually bonding with the edge of adjacent side plates.It should be noted that the mode how side plate edge joins is between two not the emphasis of the utility model protection, those skilled in the art can adopt other known modes that side plate is joined between two and finally seal volume core retainer plate according to its experience.But no matter adopt which kind of mode, as long as adopted the disclosed side plate of the utility model to do the technical scheme that spins upside down along the join axis that forms of side plate lower edge and bottom edge, all drop in the claimed scope of the utility model.
In embodiment of the present utility model, also comprise end cap, described end cap and side plate upper limb join, and final sealing volume core retainer plate.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
