Abstract
The utility model relates to a lithium battery packaging structure. The lithium battery packaging structure comprises a shell (1) and a shell cap (2), wherein the bottom of the shell (1) and the middle part of the shell cap (2) are respectively provided with a pole piece groove (3) which is used for allowing a battery pole piece to penetrate; the surface, contacted with the shell (1), of the shell cap (2) is provided with a slot (6); an opening of the shell (1) is inserted into the slot (6); screw holes (4) are distributed on the opening of the shell (1); the shell cap (2) is tightened on the shell (1) through the matching of screws (5) and the screw holes (4); a screw hole (7), which is used for a screw to penetrate through, on the shell cap (2) is depressed downwards; the depressing thickness is identical to an end surface of the screw. The lithium battery packaging structure is simple in structure, uncomplicated in machining process and low in production cost; the shell and the shell cap are mutually tightened through the screws, so that the relative position between a battery cell which is packaged inside the shell and the shell is ensured to be firm and is not changed, and the unfavorable contact phenomenon caused by the loosening of the cell can be avoided.
Description
Technical field
The utility model relates to the lithium battery production field, is specifically related to a kind of lithium cell encapsulation construction.
Background technology
Along with the development of lithium ion battery technology, lithium battery all is widely used in all trades and professions, and the particularly extensive use especially on small-sized electronic equipment at mobile communication, PAD, online notebook etc., also often be applied in electric motor car.
In existing technology, generally all there is following shortcoming in the packaging technology of lithium battery: 1, encapsulate insecurely, and position is fixing each other the battery core of lithium battery and shell to occur, has influence on the pole piece of lithium battery and extraneous contacting, and causes loose contact; 2, packaging technology is too complicated loaded down with trivial details, on the cost of producing encapsulation, continues can not fall any more always.
The utility model content
The purpose of this utility model is to provide a kind of lithium cell encapsulation construction, solves existing lithium battery encapsulation insecure, and the too complicated problem of packaging technology.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of lithium cell encapsulation construction, comprise shell and cap, the bottom of described shell and the middle part of cap are equipped with the pole piece groove passed for the battery pole piece, described cap is being provided with slot with the contacted face of shell, the faucal of described shell inserts in slot, and the punishment of the faucal of described shell is furnished with screw hole, and cap is anchored on shell by the cooperation of screw and screw hole, the upper screw place of passing for screw of described cap is recessed, and recessed thickness is identical with the end face of screw.
Further technical scheme is that the pole piece gathering sill all is installed on shell described above and cap.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, processing technology is uncomplicated, production cost is lower, and by screw, that shell and cap is mutually fastening, can guarantee that encapsulation battery battery core and the relative position between shell in the enclosure is firmly constant, avoid because the loosening loose contact phenomenon occurred of battery core.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of lithium cell encapsulation construction of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 shows an a kind of embodiment of lithium cell encapsulation construction: a kind of lithium cell encapsulation construction, comprise shell 1 and cap 2, the middle part of the bottom of described shell 1 and cap 2 is equipped with the pole piece groove 3 passed for the battery pole piece, described cap 2 is being provided with slot 6 with the contacted face of shell 1, the faucal of described shell 1 inserts in slot 6, the faucal punishment of described shell 1 is furnished with screw hole 4, cap 2 is anchored on shell 1 by the cooperation of screw 5 and screw hole 4, the upper screw passed for screw 7 places of described cap 2 are recessed, recessed thickness is identical with the end face of screw.
The preferred embodiment according to this kind of lithium cell encapsulation construction, all be equipped with pole piece gathering sill 8 on described shell 1 and cap 2.Be mainly used according to different battery sizes and the power supply link position that uses equipment, by the electrode slice specific position of leading.
Although with reference to a plurality of explanatory embodiment of the present utility model, the utility model is described here, but, should be appreciated that, those skilled in the art can design a lot of other modification and execution modes, and these are revised and within execution mode will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
