Abstract
The utility model belongs to a lithium ion battery group technological art, wherein a lithium ion battery group muff comprises a bottom plate and a fastening screw, wherein the bottom plate is fixed with a press plate and the press plate is equipped with the muff. The lithium ion battery group muffs all adopts hard aluminum alloy materials, the inner diameter of the muff is tightly matched with the outer diameter of the matched battery, and the wall thickness of the muff is small than 1mm. The utility model has scientific and reasonable design and simple process, since the weight is light and the structure is compact, the utility model is quite suitable for the application of space power source product.
Description
Technical field
The utility model belongs to the lithium ion battery technical group field, particularly relates to a kind of lithium ion battery combined sleeve.
Background technology
At present, high capacity lithium ion battery group structure is with several the fastening frame type combined structures that form of battery with two end plates and several pull bar.Its weak point is the compactness that is difficult to guarantee battery pack structure, and increases the weight of battery pack, and thermal conducting function is relatively poor.
Summary of the invention
The utility model is the solution problems of the prior art, and a kind of lithium ion battery combined sleeve is provided.
The purpose of this utility model provides a kind of simple in structure, in light weight, the lithium ion battery combined sleeve that can make the battery pack structure compactness and have good thermal conducting function.
The technical scheme that the utility model lithium ion battery combined sleeve is taked:
The lithium ion battery combined sleeve comprises base plate, and trip bolt is characterized in fixing a pressing plate on described base plate, and pressing plate is provided with sleeve.
The utility model lithium ion battery combined sleeve can also adopt following technical measures to realize:
Above-mentioned lithium ion battery combined sleeve is characterized in that described sleeve is the hard aluminium alloy material.Described base plate is the hard aluminium alloy material.Described pressing plate is the hard aluminium alloy material.Described sleeve is a column type.Described sleeve is up-small and down-big pyramid type.Described sleeve diameter and institute's distribution pond external diameter are tight fit.Described sleeve is handled through oxide isolated.Described sleeve wall thickness is less than 1 millimeter.Described base plate is provided with the socket mounting panel.
Advantage and the good effect that the utlity model has are: the technical program has solved mainly that battery pack is not compact, battery weight is big and the lithium ion battery composite structure of thermal conduction effect difference, the tube-in-tube structure battery pack replaces the frame structure battery pack, the battery pack construction weight can alleviate 1/3rd, help the heat conduction of battery in the battery pack simultaneously, make the heat of battery in the battery pack be tending towards equiblibrium mass distribution, can improve the useful life of battery.The utility model design science is reasonable, and processing is simple, and is in light weight because of it, is fit to very much the application of space power system product.
Description of drawings
Fig. 1 is the utility model lithium ion battery combined sleeve outline drawing.
Label among the figure is respectively: 1. being the socket mounting panel, 2. is pressing plate, is sleeve for trip bolt .4 3., 5. is base plate.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following examples now, and conjunction with figs. is described in detail as follows:
Please refer to Fig. 1, lithium ion battery combined sleeve lithium ion battery combined sleeve mainly is made up of base plate 5, pressing plate 2 and sleeve 4.Sleeve is fixed on the base plate by pressing plate, be fixed into by trip bolt 5 as a whole, on base plate the design have socket mounting panel 1 to be used for the installation of battery pack socket.
Base plate 5 and pressing plate 2 quality of fits require high, and backplate surface will carry out polishing, because the position in the hole on the base plate and the size dimension precision height in hole generally need to adopt combination drilling machine to process; The size of the cell that adopts according to battery pack and the size and the quantity of battery pack series connected battery number design bottom plate hole.
Equally, because pressing plate 2 quality of fits require height, clamp surface is wanted the sigma compactness polishing, because the position in the hole on the pressing plate and empty size dimension required precision height generally need the employing combination drilling machine to process; The size and the quantity of the size of the cell that the cell that adopts according to battery pack adopts and battery pack series connected battery number design pressing plate.
Sleeve 4 is fixed on battery on the base plate by pressing plate at assistance property battery surface, is transmitted on the base plate by the heat of sleeve with battery simultaneously.Therefore require the sleeve area to be convenient to more greatly conduct heat.For alleviating the weight of sleeve, the thickness of sleeve generally designs about 1mm less than 2Mm..
The material of base plate, pressing plate, sleeve and socket mounting panel can be selected metal material and the nonmetallic materials that not only have good mechanical performance but also excellent conducting performance is arranged for use, is weight reduction, can select aviation hard aluminium alloy material for use.
