18650 lithium batteries are generally applied because the advantages such as it is lightweight, capacity large, memory-less effect obtain, the mainly box hat Laser Welding encapsulation of current 18650 batteries, under the situation of inside battery thermal runaway, battery there will be the problem of blast, and the example of 18650 battery explosions is of common occurrence on the market, so improve 18650 explosion issues imperative, based on this, relate to a kind of battery plastics shell mechanism or necessary.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of battery plastics shell mechanism, and structure is simple, reasonable in design, has good insulating properties, improves the fail safe of 18650 lithium batteries, reduces risk, practical, has a extensive future.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of battery plastics shell mechanism, comprise core, positive pole ear, negative lug, positive pole cover plate, negative pole cover plate and housing, core adopts 18650 polymer core of lithium electrode sheet winding, the diameter of core is 16.8mm-17.2mm, the two ends of core lead to positive pole ear, negative lug, core arranged outside has one deck housing, positive pole ear, the arranged outside of negative lug has positive pole cover plate, negative pole cover plate, positive pole cover plate, negative pole cover plate improves positive pole rivet respectively, negative pole rivet and positive pole ear, negative lug is riveted.
As preferably, described positive pole cover plate, negative pole cover plate are plastic circular cover plate, and the thickness of positive pole cover plate, negative pole cover plate is 0.4mm, and diameter is 18.2mm.
As preferably, described housing is cylindrical plastic shell, and the interior diameter of housing is 17.4mm, and overall diameter is 18.2mm.
The beneficial effects of the utility model: the risk greatly reducing internal short-circuit of battery, reduce further the probability of happening of cell safety accident, reduce the generation of explosion accident, have ensured the fail safe that user uses.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is planar structure schematic diagram of the present utility model;
Fig. 2 is perspective view of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1-2, this embodiment is by the following technical solutions: a kind of battery plastics shell mechanism, comprise core 1, positive pole ear 2, negative lug 3, positive pole cover plate 4, negative pole cover plate 5 and housing 6, the two ends of core 1 lead to positive pole ear 2, negative lug 3, core 1 arranged outside has one deck housing 6, the arranged outside of positive pole ear 2, negative lug 3 has positive pole cover plate 4, negative pole cover plate 5, and positive pole cover plate 4, negative pole cover plate 5 improve positive pole rivet 7 respectively, negative pole rivet 8 is riveted with positive pole ear 2, negative lug 3.
It should be noted that described housing 6 adopts fireproof high-temperature resistant plastic casing to encapsulate, the interior diameter of housing 6 is 17.4mm, and overall diameter is 18.2mm.
The 18650 polymer core that this embodiment core 1 adopts lithium electrode sheet to reel, the diameter of core 1 is 17.0 ± 0.2mm, core 1 is main part, core 1 two ends just lead to, negative lug, positive pole ear 2, negative lug 3 forms the both positive and negative polarity electrode major part of discharge and recharge, positive pole cover plate 4, negative pole cover plate 5 adopts plastic circular cover plate, cover sheet thickness is 0.4mm, diameter 18.2mm, positive pole cover plate 4, negative pole cover plate 5 enters the encapsulation after shell for core 1 and outwards draws both positive and negative polarity electrode, positive pole cover plate 4, negative pole cover plate 5 to be riveted by lug and cover plate from battery core extraction electrode and is realized.
This embodiment adopts fire-resistant, resistant to elevated temperatures plastic housing to encapsulate, the safety problem of 18650 battery explosions can be solved, than box hat battery, there is better security performance, and plastics have good insulating properties, also the risk of internal short-circuit of battery is greatly reduced, reduce further the probability of happening of cell safety accident, there is wide market application foreground.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
