Description
Technical field
The utility model is related to field of batteries, more particularly to a kind of battery case.
Background technology
Lithium ion battery is a kind of rechargeable battery, and it relies primarily on lithium ion, and movement carrys out work between a positive electrode and a negative electrode.
In charge and discharge process, Li+ comes and goes insertion and deintercalation between two electrodes：During rechargable battery, Li+ is from positive pole deintercalation, by electricity
Matter insertion negative pole is solved, negative pole is in rich lithium state；It is then opposite during electric discharge.Because lithium ion battery has small volume, lightweight, electricity
Amount is strong, environmental protection the features such as, be widely used in industrial production and daily life.
Battery case is the important component of lithium ion battery, and the battery case of existing square structure is by housing and cover plate structure
Into, as shown in figure 1, the housing 11 of the battery case and cover plate 12 are inconvenient, need to welded in its side in welding,
After the completion of being welded a side, plumb joint position is adjusted, another side is welded, using such a mode successively to 4 sides
Face is welded, and welding efficiency is relatively low, thus, is badly in need of solving.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, a kind of battery case is provided, to solve the shell of existing battery case
Welding inconvenience, the problem of welding efficiency is low when body is assembled with cover plate.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of battery case, includes the housing and the cover plate of square structure of square structure, and the upper end of the housing sets opening,
Locating notch is provided with the opening, the depth of the locating notch is identical with the height of cover plate, and the cover plate is arranged at shell
In the locating notch of body, and the upper surface of cover plate is flushed with the upper surface of housing.
As a kind of preferred scheme of the present utility model, nickel coating is provided with the inwall of the housing and outer surface.
As a kind of preferred scheme of the present utility model, the housing is including horizontally disposed bottom plate and is vertically disposed to bottom
Front side board, back side panel, left plate, the right plate of plate surrounding.
As a kind of preferred scheme of the present utility model, the bottom plate is with front side board, back side panel, left plate, right plate
Integrative-structure.
The beneficial effects of the utility model are that a kind of battery case sets locating notch at opening, and cover plate is arranged at
In locating notch, the upper surface of cover plate is flushed with the upper surface of housing so that weld seam is respectively positioned on housing upper surface, in same flat
Face, is easy to welding, substantially increases welding efficiency.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.It can manage
Solution, embodiment described herein is used only for explaining the utility model, rather than limits of the present utility model.
It refer to shown in Fig. 2 and Fig. 3, Fig. 2 is a kind of structural representation of battery case of the utility model；Fig. 3 is shown in Fig. 2
A kind of enlarged drawing of battery case at A.
In the present embodiment, a kind of battery case includes the housing 21 and the cover plate 22 of square structure of square structure, the shell
Body 21 includes horizontally disposed bottom plate and is vertically disposed to front side board, back side panel, left plate, the right plate of bottom plate surrounding, described
Bottom plate is structure as a whole with front side board, back side panel, left plate, right plate, is respectively provided with the inwall of the housing 21 and outer surface
There is nickel coating, the upper end of the housing 21 is set is provided with locating notch, the depth of the locating notch at opening, the opening
Identical with the height of cover plate 22, the cover plate 22 is arranged in the locating notch of housing 21, and upper surface and the housing of cover plate 22
21 upper surface is flushed.
In the present embodiment, the form for the step slot structure that locating notch is used, it is set on left plate, right plate respectively
The step slot structure, to play a part of positioning cover plate, and then is easy on welding, its front side board, back side panel and is not provided with, be worth
One is mentioned that, the utility model not limited to this, step slot structure can be also set on front side board, back side panel, also or in front side
Plate, back side panel, left plate, right plate are respectively provided with step slot structure, and the present embodiment is selected on the less left plate of shell length, the right side
Step groove is set on side plate, is that, with reference to the consideration after positioning intensity and cost, it is easy to processing, greatly reduces processing cost.
Above example is to elaborate general principle of the present utility model and characteristic, and the utility model is not by above-mentioned implementation
Example limitation, on the premise of the utility model spirit and scope are not departed from, the utility model also has various change and change, these
Changes and modifications are both fallen within the range of claimed the utility model.Scope is claimed by appended right in the utility model
Claim is defined.
