Description
Technical field
The utility model relates to a kind of syndeton of lithium ion battery group, belongs to the technical field of lithium ion battery.
Technical background
At present, lithium ion battery is by battery case, battery pack, and battery connecting apparatus, baffle discharge and recharge elements combination such as socket and form.Because about single bag lithium battery voltage platform 3.7V, when the needs battery is exported more high voltage and capacity, just can use after just the electric core connection in series-parallel of several single bags need being become battery pack, wherein the effect of rebound is the jockey that the parallel connection of battery list bag, series connection or connection in series-parallel is become battery pack.Application number is the Chinese patent of a kind of rectangular lithium ion power battery pack of 200320128891.6, it discloses a kind of power battery pack that comprises cell body, cell body fastener, wherein: the cell body fastener comprises pressing plate and connecting band, pressing plate compresses cell body along the orientation of each battery in the cell body, is linked to each other and is made cell body fastening by connecting band.This battery pack unit volume energy density height, safe and reliable, the battery pack fixture structure is simple, and is fastening effective.But said structure is comparatively complicated, dismounting trouble, short circuit easily.
Chang Yong connected mode is connected lug with the scolding tin welding method for using the fixing method of Luo silk with rebound in addition.For using the less battery pack of electric current, use rebound to have advantage more easily, be widely used in the battery pack of flexible package and polymer.Application number is the Chinese patent of 200620001192.9 safe battery assembling distribution structure, and it discloses a kind of safe battery assembling distribution structure, and wherein: the cell body assembly structure comprises battery container, electric core, change-over panel and loam cake.The position of the corresponding cell polar ear of described change-over panel offers through-hole groove, and lug is fixed on the keyset by the Luo silk after passing through-hole groove.This rebound is the method for fluting in the middle of adopting.But inconvenience when this rebound goes out the battery pack of lug (both positive and negative polarity is oppositely drawn) at assembling two causes short circuit between the electric core of single bag easily, influences the operating efficiency of battery pack assembling, therefore is necessary existing rebound structure is improved.
Summary of the invention
The utility model purpose is to provide a kind of and connects the lithium ion battery that the electric core of single bag becomes battery pack by rebound, has solved the problems referred to above that prior art exists.
Another object of the present invention provides the good lithium ion battery of a kind of mechanical strength.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of lithium ion battery, comprise electric core unit of forming side by side by some electric cores of single bag that have lug and the rebound that connects the electric core of single bag, described rebound has in order to insert the lug groove of single bag cell polar ear, it is characterized in that: the lug groove of rebound is divided into two kinds on Tong Bian and obstructed limit, two kinds of lug grooves on every rebound are alternately arranged the lug groove difference that the rebound at electric core unit two ends is relative.
Inconvenient in order to overcome existing rebound assembling, influence the battery pack efficiency of assembling, the utility model spy has carried out above-mentioned improvement to the rebound structure.
The lug groove of such rebound alternately is Tong Bian-obstructed limit from top to bottom, and the lug groove of the rebound on the opposite end of electric core then alternately is obstructed Bian-Tong Bian from top to bottom.
When adopting battery pack of the present utility model to assemble, after will singly wrapping in the electric core one end lug insertion lug groove earlier, another lug inserts from the logical limit of corresponding rebound groove, and it is simple that this method has assembling, and operate miss causes short circuit between the electric core of single bag when having avoided assembling; Comparing whole lug grooves simultaneously all is the rebound on logical limit, and new rebound has better mechanical strength, helps rebound production and battery assembly technology smooth implementation.
As preferably, collector is connected by spot welding with lug in the electric core of single bag, and the electric core of described single bag is packed with aluminum-plastic composite membrane.
As preferably, battery voltage is between 12-48V.
As preferably, battery pole ear is oppositely drawn from two ends.
Therefore, the utlity model has simple in structurely and firm, simultaneously the mechanical strength height is easy to characteristics such as dismounting.

Fig. 2 is the front view of Fig. 1 rebound face;
Fig. 3 is the end view of Fig. 2;
Fig. 4 is the end view of Fig. 3.
1. rebounds among the figure, the electric core of 2. single bag, 3. lug, 4. not the lug groove on logical limit, 5. the lug groove on logical limit.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, 2, 3, collector and lug 3 are connected by spot welding in the electric core 2 of single bag, and electric core is packed with aluminum-plastic composite membrane; Battery pole ear 3 becomes battery pack by rebound 2 connection in series-parallel.10 electric cores 2 of single bag are by the battery pack that connect to form of rebound, and the two ends of battery pack all are provided with rebound 2, and interleaved on the rebound 2 have two kinds of lug grooves, and described two kinds of lug grooves are respectively logical limit lug grooves 5 and lead to limit lug groove 4.The relative lug groove difference on two rebounds at electric core two ends simultaneously, promptly the lug groove on is the lug groove on logical limit, corresponding lug groove be the lug groove that does not lead to the limit on the relative rebound.In the embodiment shown in fig. 1, during the battery pack assembling, after will singly wrapping in the logical limit of electric core 2 one end lugs, the 3 insertion rebounds lug groove 4 earlier, another lug 3 inserts from the lug groove 5 on the logical limit of rebound, after electricity core and rebound all assemble, use scolding tin will need series-parallel lug and rebound to be weldingly fixed on together, it is simple that this method has assembling, operate miss causes the short circuit of battery list bag when having avoided assembling, has improved efficiency of assembling.Compare the rebound that whole lug grooves reach the limit simultaneously, new rebound has better mechanical strength, helps rebound production and battery assembly technology smooth implementation.
