Specific embodiment
Below with reference to embodiment, the present invention will be further described, but is not limited to the content on specification.
The invention discloses a kind of batteries to protect structure, including protective shell 10, and protective shell 10, which has, accommodates battery
Accommodating chamber 15, protective shell 10 are arranged in battery mounting shell, and battery is arranged in accommodating chamber.The present invention passes through setting protective shell
10, it reduces battery and is put into after mounting shell a possibility that distorting, effectively prevent aluminum hull surface caused by expanding because of battery recessed
Convex injustice.
In the above-described embodiments, protective shell 10 includes upper housing 11 and lower case 12, and lower case 12 and upper housing 11 fasten,
Upper housing 11 and the clamping of lower case 12 are arranged.It is provided with buckle 20 or card slot 30 on upper housing 11, is provided with phase in lower case 12
Matched card slot 30 or buckle 20.When assembly, only buckle 20 and card slot 30 need to be subjected to alignment pressing, and can be according to core
The slight errors of thickness slightly adjust the buckle and card slot of protective shell, and assembly can be completed, to improve assembly efficiency.
Buckle can be bullet-shaped, and card slot is sky nest shape corresponding with buckle.In assembling process, simply buckle
It is pressed with after card slot alignment, that is, completes the assembly of protective shell, buckling maximum circular diameter is 0.5mm, the greatest circle of card slot
Diameter is 0.55mm.
In the above-described embodiments, corresponding on upper housing 11 has the first tab protection portion 13 at the tab position of battery；
There is second tab protection portion 14 corresponding with the first tab protection portion 13 in lower case 12；First tab protection portion 13 and
The guard space for protecting tab is formed between two tab protection portion 14, tab is located in guard space, the protection of the first tab
Portion with a thickness of 2-20mm, the second tab protection portion with a thickness of 2-20mm.Since tab is usually the groups such as aluminium or copper, nickel
At being all grade even micron-sized thickness after being compressed into collector, be particularly easy to deformation, damaged, therefore, pass through setting
Tab is arranged in guard space, can completely cut off the contact with aluminum hull, prevent tab from being scratched by tab protection portion, and will
Tab is fixed in the space in gap, can be prevented tab from misplacing because of core transfer well, be prevented tab mobile
It bends in the process, effectively prevent that breakage occurs, fixed core can also be avoided in the position of aluminum hull because of the internal resistance of cell
Increase and reduce the energy conversion efficiency of battery.
In the above-described embodiments, the shape of accommodating chamber 15 and the shape of battery match, and battery core outer surface and guarantor
The inner wall of protective case 10 fits.Battery is core, has the two opposite arcwall faces formed due to winding in core, due to
The shape of accommodating chamber and the shape of battery match, and have the arcuate structure of corresponding arcwall face on protective shell, and radian is 60 °-
180 °, compared to conventional square structure, the space inside aluminum hull is saved, is put into inside aluminum hull after 1-5 core is in parallel,
It can set cambered structure to corresponding with core number, each cambered structure arc angles are consistent.
In the above-described embodiments, battery is core, has the two opposite arcwall faces formed due to winding in core；
Protective shell 10 has first area and second area, and first area is corresponding with the position of arcwall face, the firstth area on protective shell 10
Region other than domain is second area, and 10 thickness of protective shell of first area is greater than 10 thickness of protective shell of second area.Specifically
First area protective shell with a thickness of 2mm, the protective shell of second area is with a thickness of 0.5mm.Due to the first of corresponding arcwall face
Region is punched, and by making the thickness of first area be greater than the thickness of second area, can satisfy the aperture to punching
Requirement.
In the above-described embodiments, 10 material of protective shell includes one of following material or a variety of: polypropylene, poly- carbonic acid
Ester, polyimides, polyethylene or polyethylene terephthalate.By using above-mentioned material, it is resistant to lithium ion battery electrolysis
The corrosion of liquid, and protective shell has the ability for inhaling a certain amount of electrolyte, it can be in the premise for guaranteeing core electrolyte inside amount
Under, the electrolyte as much as possible between reduction aluminum hull gap.
In the above-described embodiments, upper housing 11 is an integral molding structure, and lower case 12 is an integral molding structure.Facilitating peace
While dress, reliability is improved.
According to another aspect of the present invention, a kind of battery is also disclosed, protects structure including above-mentioned battery.
