Fig. 1 is the sectional structure schematic diagram of the battery case of the utility model first embodiment.
Fig. 2 is the upward view of the metal cover board of the utility model first embodiment.
Fig. 3 is the cutaway view of the metal cover board of the utility model first embodiment.
Fig. 4 is the sectional structure schematic diagram of the battery case of the utility model second embodiment.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1 to Figure 3, the utility model first embodiment a kind of lithium battery structure is provided, comprise battery case 100, it in order to an accommodating battery 2, and then is assembled into lithium ion battery, and described battery case 100 comprises housing 3 and a upper cover 4.
Described housing 3 has base plate 31, sidewall 32 and an accommodation space 30, and described accommodation space 30 is defined by described base plate 31 and sidewall 32 and forms, and in order to accommodating described battery 2, described base plate 31 and described sidewall 32 are metal sheet and one-body molded.
Described upper cover 4 correspondence is arranged on described housing 3 and closes described accommodation space 30, described upper cover 4 has metal cover board 41 and two insulating barriers 42, described metal cover board 41 is in order to be combined on the sidewall 32 of described housing 3, described metal cover board 41 has two electrode through holes 410, one be positioned at bottom annular convex 411, two sheet metals 412 and two electrode terminals 413, described annular convex 411 forms annular recessed portion (sign) at the top relative position of described metal cover board 41, and arrange separately with described metal cover board 41 periphery, the insulating barrier 42 of the bottom of described metal cover board 41 covers the annular convex 411 of described metal cover board 41.
Described two insulating barriers 42 are separately positioned on top and the bottom of described metal cover board 41, and described sheet metal 412 is together imbedded in the plastics of described insulating barrier 42 with described metal cover board 41, and described electrode terminal 413 is separately fixed on corresponding described sheet metal 412.
By above-mentioned design, utilize and form described annular convex 411 and relative annular recessed portion thereof bottom described metal cover board 41, the insulating barrier 42 of bottom is made to cover described annular convex 411, the insulating barrier 42 at top covers described annular recessed portion, because the insulating barrier 42 at bottom and top is similar, its thickness disparity is little, additionally must carry out processing and correct, can reduce manufacturing cost to avoid producing distortion.
As shown in Figure 4, for the lithium battery structure of the improvement of the utility model second embodiment, comprise battery case 100, it is similar in appearance to the first embodiment, the difference of the present embodiment is: described upper cover 4 forms a depressed part in the middle of described metal cover board 41, then arranges two insulating barriers 42 at the top of described metal cover board 41 and bottom respectively; Described housing 3 to have on base plate 31, sidewall 32, on wall extension 33, scalariform portion 34, once wall extension 35 and once scalariform portion 36, described upper wall extension 33 extends from the upper limb of described sidewall 32 and protrudes from outside described sidewall 32, described upper scalariform portion 34 is formed at the inner side of described upper wall extension 33, and by the lateral margin setting for described metal cover board 41.Described base plate 32 is combined in bottom described sidewall 31, and described downward-extension wall 35 extends from the lower edge of described sidewall 31 and protrudes from outside described sidewall 31, and described lower scalariform portion 36 is formed at the inner side of described downward-extension wall 35, and by the lateral margin setting for described base plate 32.
By above-mentioned design, utilize described upper scalariform portion 34 towards unfilled corner in described housing 3 and coordinate the lateral margin setting for described metal cover board 41, described metal cover board 41 is made to be positioned over described upper scalariform portion 34 that is limited, conveniently carry out follow-up welding procedure and the operation that need not position again, in like manner, described downward-extension wall 35 also can for the lateral margin setting of described base plate 32, make described base plate 32 be positioned over described downward-extension wall 35 that is limited and avoid relocating in addition described metal cover board 41, thus can simplify the operation of its welding processing.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
