Detailed description of the invention
In order to be more clearly understood from the technical characteristic of utility model, purpose and effect, now comparison accompanying drawing illustrates this practicality
Novel detailed description of the invention, the most identical label represents identical part.
In this article, " schematically " expression " serves as example, example or explanation ", " should not show being described herein as
Meaning property " any diagram, embodiment be construed to a kind of preferred or more advantage technical scheme.
For making simplified form, only schematically show and this utility model relevant portion in each figure, and do not represent it
Practical structures as product.It addition, so that simplified form readily appreciates, some figure has identical structure or function
Parts, only symbolically depict one of them, or have only marked one of them.
The technical problem of the full-length set can not be reached in order to solve the length in groups of lithium ion battery in prior art, this
Utility model provides a kind of lithium ion battery, its in groups after be sized to be adjusted in certain scope, thus reach
To the full-length set, meet the assembling requirement with other parts, it is achieved being reliably connected of each parts of module, improve electricity
The serviceability in pond.
Fig. 1 is the structural representation of lithium ion battery of the present utility model.Fig. 2 is a part of battery mould in this utility model
The explosive view of group unit.As depicted in figs. 1 and 2, in one embodiment, a kind of lithium ion battery 1, including:
First end plate 10；
Second end plate 11；
Battery modules 20, battery modules 20 is arranged between the first end plate 10 and the second end plate 11, wherein, battery modules
20 include multiple battery modules unit 21 being arranged side by side, and each battery modules unit 21 includes foam 22；With
Bandage 30, together with the first end plate 10 is adjustably secured by bandage 30 with the second end plate 11 and battery modules 20,
To adjust the distance between the first end plate 10 and the second end plate 11 by extruding foam 22.
In the present embodiment, owing to foam 22 is for having resilient Heat Conduction Material, it has compressibility and load ability,
When by instrument tighten bandage 30 extrude foam 22 time, the thickness of foam 22 is compressed reduction, then the first end plate 10 and
Distance between two end plates 11 can reduce, thus reduces the length of whole lithium ion battery 1；When releasing by loosening bandage 30
When putting foam 22, the thickness resiliency of foam 22, then the distance between the first end plate 10 and the second end plate 11 can increase,
Thus increase the length of whole lithium ion battery 1.By coordinating of length-adjustable bandage 30 and foam 22, lithium ion
The length in groups of battery 1 can be adjusted within the specific limits, thus full-length when reaching design, to reach setting
Matching requirements, it is achieved with coordinating of other each accessories.So, not only reduce the machining accuracy of battery modules unit 21,
And improve the length accuracy of lithium ion battery 1, thus meet the assembling requirement with other parts, it is achieved each zero of module
Being reliably connected of part, improves the serviceability of battery.It addition, bandage 30 has, bearing capacity is strong, easily processing, easy to assembly,
The advantage of low cost, thus beneficially battery modules unit 21 in groups, is greatly improved production efficiency.
As in figure 2 it is shown, specifically, each battery modules unit 21 includes:
Cell 211；
Heat-conducting plate 213, foam 22 is arranged between cell 211 and heat-conducting plate 213, and cell 211 of fitting,
To fully absorb the heat of cell 211, and by this heat conduction to heat-conducting plate 213；With
Battery frame 212, cell 211 is fixed in battery frame 212.
Wherein, shown in Fig. 1 and Fig. 2, the first end plate 10 and the second end plate 11 are respectively provided with for accommodating consolidating of bandage 30
Determining groove, the position of fixing groove is the fixed position of bandage 30, and bandage 30 is arranged in fixing groove, thus avoids bandage 30
In use cause due to moving of position getting loose, thus lose the dimension limitation to lithium ion battery.
Wherein, the quantity of bandage 30 can be selected according to the binding power of bandage and the fixed position on lithium ion battery
Select.Such as, as shown in fig. 1, lithium ion battery 1 includes two bandages 30, each bandage 30 along with lithium ion battery
Parallel direction, bottom surface extend, be separately positioned on bottom surface and the position of end face of neighbouring lithium ion battery 1, from the first end plate
10, the outside of the second end plate 11 and battery modules 20 is bound together.Bandage 30 the most as shown in Figure 1
Setting direction, lithium ion battery 1 can include one or more bandage 30.
It is understood that bandage 30 can extend along with lithium ion battery 1 direction that side is parallel, this side with
First end plate the 10, second end plate 20 is vertical, and similarly, lithium ion battery 1 can include two bandages 30, each bandage 30
Extend along with lithium ion battery 1 direction that side is parallel, be separately positioned on two of neighbouring lithium ion battery 1 relatively
The position of side, is bound together from the outside of first end plate the 10, second end plate 11 and battery modules 20.
The present embodiment takes full advantage of the processing strong, easy of bandage 30 bearing capacity, easy to assembly, the advantage of low cost, concrement vacuole
Cotton 22 compressibilities having and the strong feature of bearing capacity, greatly reduce the requirement on machining accuracy of battery modules unit 20,
Make lithium ion battery 1 can reach the full-length set, be conducive to the connection of the miscellaneous parts such as itself and battery pole ear, from
And improve the serviceability of battery；And it is easier to cell in groups, is greatly improved production efficiency.
