Description
Technical field
This utility model relates to technical field of lithium batteries, relates in particular to a kind of lithium battery core casing.
Background technology
The structure of lithium cell core mainly includes a housing at present, and housing is built-in to be placed with electrolyte solution and uses lamination or volume
Install around positive plate, isolating membrane and the negative plate of the assembling of formula formula.Wherein, each positive plate welds with positive pole ear respectively, more simultaneously
Being welded on the bottom of the positive terminal of housing, each negative plate welds with negative lug respectively, then is welded on the negative of housing simultaneously
The bottom of pole binding post.And the top of positive terminal and negative terminal is respectively equipped with external screw thread, so as to screwing togather one respectively
After nut, fix different binding posts respectively, with outside output power.
General lithium battery uses ambient temperature to be at about-10~40 degree, but has some hot operation district working environments
Likely reaching 50~60 degree, temperature is the highest, and the capacity of lithium battery will be the biggest.But because capacity becomes big, the life-span of battery
Will shorten.
When the temperature increases, the electrolyte in lithium battery may expand because of the rising of temperature, and liquid volume increases,
And adjoint be the deformation of lithium battery case, the weak lithium battery core casing of some intensity may break because of this deformation repeatedly
Bad, serious even can explode.
Summary of the invention
The purpose of this utility model is the defect for above-mentioned prior art, it is provided that a kind of lithium battery core casing, overcomes existing
The lithium battery core casing having technology may cause core shell to destroy the defect that blast even occurs because temperature raises.
To achieve these goals, the technical solution of the utility model is:
A kind of lithium battery core casing, including a long cube and shell body and the inner housing with hollow cavity, described inner shell
Body and the top end opening of shell body, the top end cover unification cover plate of this inner housing, to be collectively forming an inner space;Described inner housing
Inner circumferential be smooth surface, the outer wall of perimembranous and the outer wall of bottom are provided with some walings and cross reinforcing, institute
State waling and cross reinforcing intersects vertically also and inner housing is one-body molded;The inner and outer wall of described shell body is light
Sliding surface, described inner housing is plugged in the hollow cavity of shell body;Described cover plate arranges an air-vent, and this air-vent has one
Counterbore, described counterbore is disposed with foundation ring, thin film, trim ring, ring for fixing from bottom to up, described foundation ring, thin film, trim ring, fixing
Circle stacks gradually and is contained in counterbore.
As the improvement to technique scheme, described inner housing is plastic casing, and described shell body is steel housings.
As the improvement to technique scheme, described shell body coordinates with inner housing slight interference.This design, can be both square
Just inner housing is installed, and the installation of inner housing is good.
Compared with prior art, this utility model has the advantage that with good effect and is:
Lithium battery core casing of the present utility model, is made up of inner and outer shell, and the periphery of inner housing arranges the reinforcement intersected in length and breadth
Muscle, and one-body molded with housing, the intensity of inner housing can be strengthened, prevent core shell deformation after being heated, the periphery of shell body
For smooth surface, in that context it may be convenient to mobile or fixing;The cover plate of inner housing arranges thin film, tight bond in the counterbore of cover plate,
When gas pressure in housing arrives preset pressure, thin film just can be allowed to pop, therefore, can be prevented effectively from because of explosion-proof thin film ahead of time
The product waste popped and cause, and extend the service life of product.Lithium battery core casing of the present utility model comes in terms of two
Ensure the safe handling of lithium battery core casing, overcome the lithium battery core casing of prior art may cause core shell because temperature raises
Destroy the defect that blast even occurs.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, any modification, equivalent substitution and improvement etc. made, should be included in of the present utility model
Within protection domain.
As it is shown in figure 1, lithium battery core casing of the present utility model, including a long cube and the shell body with hollow cavity
2 and inner housing 1, described inner housing 1 and the top end opening of shell body 2, the top end cover unification cover plate 5 of this inner housing 1, with common shape
Become an inner space;The inner circumferential of described inner housing 1 is smooth surface, and the outer wall of perimembranous and the outer wall of bottom are provided with some and indulge
