Abstract
The utility model discloses a lithium ion battery coiled core fastening structure, belonging to the field of lithium ion batteries and aiming at providing a lithium ion battery coiled core fastening structure with simple structure and high qualified rate of finished products in production process. The structure comprises a battery coiled core and a battery shell and the upper end and lower end of the battery coiled core are respectively provided with a layer of elastic rubber insulation pad. The lithium ion battery coiled core fastening structure enhances the anti-shake performance of the battery coiled core, improves the qualified rate of the finished products of batteries and is applicable to the manufacturing and application fields of the lithium ion batteries.
Description
Technical field
The utility model relates to a kind of lithium ion battery, in particular, relates to a kind of fastening structure of lithium ion battery coil core.
Background technology
In the prior art, lithium ion battery structure includes volume core, positive and negative lug, shell, cover plate, insulator, in lithium ion battery and production process, after positive and negative lug on the cover board welds, there is certain sky to stay the gap between cover plate and volume core head or the afterbody, in the process that battery is produced in batches, tend to occur following phenomenon, for cover plate and housing can fit like a glove, the volume core must be admitted to housing completely, also will beat facing to the bottom of battery simultaneously, this will cause positive and negative lug welding to come off.Again because battery is assembled into the finished product battery, also need further processing just can become complete finished product battery, if the housing that battery and client order in the process of processing does not match, also can beat facing to the battery upper and lower side, the process of beaing may cause battery plus-negative plate contact short circuit or both positive and negative polarity sealing-off to cause opening circuit, cause the product disqualification rate higher.
Summary of the invention
Technical purpose of the present utility model is to solve in the prior art, when the volume core of battery and shell assemble, owing to beaing the phenomenon that causes the welding of battery positive and negative electrode to come off or open circuit, provide a kind of lithium ion battery coil core fastening structure simple in structure, that product qualified rate is high in process of production.
For realizing above technical purpose, the technical solution of the utility model is
A kind of lithium ion battery coil core robust construction includes battery roll core and battery case, it is characterized in that: at the upper and lower side of described battery roll core, be respectively equipped with one deck caoutchouc elasticity insulation cushion.
In structure of the present utility model, even battery beats arbitrarily in process of production, can both avoid the welding of positive and negative lug to come off bad or the both positive and negative polarity contact causes breaking phenomena, the antidetonation that has improved battery is greatly swung performance and has been improved the qualification rate of finished product.
Useful technique effect of the present utility model is: because volume core upper and lower side and the shell and the cover plate contact position of battery all are provided with one deck caoutchouc elasticity insulation cushion, strengthened the anti-seismic performance of battery roll core, improved the qualification rate of battery finished product.
Description of drawings
Fig. 1 is the structural representation of an embodiment battery roll core of the utility model;
Fig. 2 is that embodiment battery roll core of the utility model is assemblied in the structural representation in the shell.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2, describe embodiment of the present utility model in detail: in the utility model lithium ion battery coil core robust construction, include battery roll core 1 and battery case 2, above two electrodes 3, be provided with cover plate 4, at the upper and lower side of described battery roll core, be respectively equipped with one deck caoutchouc elasticity insulation cushion 5.In structure of the present utility model, even battery beats arbitrarily in process of production, can both avoid the welding of positive and negative lug to come off bad or the both positive and negative polarity contact causes breaking phenomena, the antidetonation that has improved battery is greatly swung performance and has been improved the qualification rate of finished product.In production operation, caoutchouc elasticity insulation cushion 5 is sticked on the upper and lower side position of battery roll core.Volume core again and positive and negative lug and cover plate welding.The volume core body is sent in the battery case 2 fully.Battery bottom beats several following facing to work top, plug into fully up to the edge of cover plate 1 and the edge of battery case 2, has formed battery as shown in Figure 2.
In a word, in the utility model,, strengthened the anti-seismic performance of battery roll core, improved the qualification rate of battery finished product because volume core upper and lower side and the shell and the cover plate contact position of battery all are provided with one deck caoutchouc elasticity insulation cushion; It is a kind of not only practical but also novel structural improvement in this area.
