Battery steel shell there are the following problems：Block and the nickel coating of battery steel shell perisporium terminal part after bending be also together removed,
Protection of the steel material of perisporium end due to losing electrodeposited coating, is easier to get rusty.And perisporium upper end bending process
Middle flow of metal is serious, is easily broken, and increases the rate of defective products, the Productive statistics of enterprise is increased, while existing electricity
Pond box hat needs precompressed during encapsulation battery battery core, and fixation is then packaged again, increases the production process of battery, increases
Production time of battery.
Utility model content
The purpose of this utility model is to provide a kind of novel battery box hat structure, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of novel battery box hat structure, including steel
Drain pan, the cavity of steel sheel and drain pan the formation one end open, the steel sheel inwall are provided with below housing, the steel sheel
Provided with nickel coating, the steel sheel top is divided into beam oral area, and the inwall of the beam oral area is the oblique line stretched out, the beam mouthful
Portion is provided with parcel, and the parcel is made up of circular arc inwall and circular arc outer wall, and the diameter of the circular arc outer wall is more than circular arc
The diameter of inwall, the upper end of the circular arc outer wall extends to form otch below to the inwall of beam oral area, the following end of the otch
End is connected to form otch top with the outer wall of beam oral area, and the steel sheel bottom, which is divided on receiving portion, the inwall of the drain pan, to be set
It is fluted.
It is preferred that, the steel sheel is cylindric.
It is preferred that, the wall thickness of the beam oral area successively decreases from top to bottom.
It is preferred that, the otch top and otch it is following between angle be not more than 45 degree.
It is preferred that, the half of the following of length no more than beam oral area thickness of the otch.
Compared with prior art, the beneficial effects of the utility model are：This novel battery box hat structure, in battery steel shell
Perisporium upper end is provided with beam oral area, and beam mouth inner wall is skewed, convenient to load battery battery core in battery steel shell, raising production effect
Rate, while being easy to the preliminary fixation of battery battery core, is provided with parcel on beam oral area, bound edge processing is carried out using traditional bending
Afterwards, the perisporium end after shaping is mutually closely packed together as the base and side of cut surface, it is to avoid battery steel shell perisporium end
There is phenomenon of getting rusty because of the destruction of nickel coating.
