With lower cover contact edge.
The lithium ion battery pack outer case, its main feature is that：It is equipped with labeling sticky position in upper cover and lower cap surface, is convenient for
Paste LOGO and points for attention mark.
The utility model has the advantages and positive effects of：
Lithium ion battery pack outer case is as a result of the completely new technical solution of the utility model, compared with prior art, this
Utility model evident characteristic：First, a kind of lithium ion battery pack outer case of the utility model, upper cover and lower cover are noted using same mold
It moulds, cost input is greatly saved；I-shaped design so that battery pack be packed into and take out battery compartment during just
In hand-held so that operating process is easy；Enlarged head and small head, enlarged head intracavity space is larger to be conducive to Li-ion batteries piles BMS
Installation, and improve the radiating efficiencys of BMS during the work time；The design on enlarged head and small head is conducive to battery pack in battery
Fixation in storehouse, and shell is integrally formed using ABS plastic, has very strong toughness, intensity and insulating properties, in very great Cheng
Battery pack is protected on degree；Battery case outlet hole is located in enlarged head groove so that conducting wire will not be electric in use
Pond bulkhead and battery case squeeze, and to protect conducting wire, reduce security risk；Shell corner uses designed arc-shaped appearance so that
Shell can be contacted with battery bulkhead well, avoided battery compartment corner flash and injured to the puncture of battery case, extended
Service life；Use groove and convex design in upper cover and lower lid housing contact edge, when upper and lower covers zoarium, the groove of upper cover and
Protrusion corresponds to the protrusion and groove of lower cover so that upper and lower covers combination is more secured, avoids the appearance of upper and lower covers dislocation, and protects
Housing slot is not inserted by external object, further protects the safety of battery pack；It is all provided with that have counted trade mark viscous in upper and lower cap surface
Position is pasted, stickup company LOGO and points for attention are convenient for.
