Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
Below in conjunction with specific embodiment, realization of the present utility model is described in detail.
With reference to shown in Fig. 1～5, for a preferred embodiment of this utility model offer.
The rupture disk of the present embodiment offer and the integrated formed structure of rotating sheet, be used on the cover plate of lithium battery,
Certainly, its utilization is not limited to lithium battery, it is also possible to be in other various batteries, such as chargeable electricity
Pond etc..
The integrated formed structure of rupture disk and rotating sheet includes plate body 11, rupture disk 12 and rotating sheet 13,
Wherein, plate body 11, rupture disk 12 and rotating sheet 13 are formed in one, plate body 11 in the form of sheets, explosion
Sheet 12 and rotating sheet 13 are separately positioned on plate body 11, and arrange separately.
In actual use, plate body 11 is arranged on the cover plate of battery, and the upper end that cover plate is sealed on housing is opened
Mouthful, so, when the pressure in battery increases, namely the pressure in housing increases, first, when pressure is big
When certain value, generally, the setting value of pressure is 0.5MPa, and rotating sheet 13 then can overturn upward,
Make positive pole and the negative pole short circuit of battery, it is to avoid the pressure in housing continues to increase；Effect when rotating sheet 13
Lost efficacy, or when the pressure in housing persistently increases, when pressure is more than certain value, generally, pressure
The setting value of power is 0.8MPa, rupture disk 12 explosion the most under the effect of the pressure, and the pressure in housing then can
Leak, to avoid whole battery explosion.
The rupture disk of above-mentioned offer and the integrated formed structure of rotating sheet, rupture disk 12 and rotating sheet 13 molding
On plate body 11, and plate body 11, rupture disk 12 and rotating sheet 13 are integrated, so, the most not
Need the most independent manufacture molding rupture disk 12 and rotating sheet 13, be greatly saved manufacturing cost, and in assembling
During to the cover plate of battery, disposable assembling then can, be greatly simplified structure, and assembling process be simple
Convenient and convenient.
In the present embodiment, plate body 11 is formed with blast hole 15 and tumble port 16, blast hole 15 and turning over
Turning hole 16 to arrange separately, rupture disk 12 is arranged in blast hole 15, and encloses blast hole 15, turns over
Rotor 13 is arranged in tumble port 16, and encloses tumble port 16.By by rupture disk 12 and rotating sheet
13 are correspondingly arranged in blast hole 15 and tumble port 16 respectively, when the pressure in housing increases, favorably
Air pressure in housing is concentrated and is acted on rupture disk 12 and rotating sheet 13, is greatly enhanced rupture disk 12
And the reaction sensitivity of rotating sheet 13 and precision.
Specifically, blast hole 15 and rupture disk 12 are in ellipticity, certainly, and blast hole 15 and rupture disk 12
Can also be in other various shapes, such as toroidal, or different form etc..
For the ease of the quick bursting of rupture disk 12, rupture disk 12 being carved and is provided with groove trace, groove trace is permissible
Setting in a variety of shapes.
Rupture disk 12 is arranged on the top of blast hole 15, and the upper surface of rupture disk 12 and plate body 11 is upper
Flush is arranged, and so, lower end perforate is then formed at the top of blast hole 15, and with rupture disk 12 as the end
The explosion recess hole in portion, when the pressure in housing increases, air pressure can be concentrated through explosion recess hole
Lower ending opening act on rupture disk 12.
In the present embodiment, the middle part of rotating sheet 13 is the most projecting, ledge in the middle part of formation, and upset
The upper end of the middle part ledge of sheet 13 is provided with abutting post 14, so, when the pressure in housing increases to
During certain value, air pressure acts on whole rotating sheet 13, and rotating sheet 13 arches upward upward so that abut
Post 14 is connected with electrode, it is achieved the positive pole of battery and negative pole short circuit.
Specifically, the periphery of rotating sheet 13 is connected on the sidewall of tumble port 16, and the sidewall of rotating sheet 13
Being downwardly inclined setting, form sloped sidewall, sloped sidewall meets at middle part ledge, so, at air
Pressure under, beneficially rotating sheet 13 overturns upward.
For the ease of abutting the setting of post 14, the middle part ledge of rotating sheet 13 is that horizontal plate is arranged, when
So, according to actual needs, middle part ledge can also be that other various shapes are arranged.
It addition, for the ease of the upset of rotating sheet 13, along the periphery of rotating sheet 13 to the direction at middle part,
The thickness of rotating sheet 13 is gradually increased, so, say, that rotating sheet 13 and the junction of tumble port 16
Thickness be the thinnest.
In the present embodiment, the rounded shape of tumble port 16, so, when rotating sheet 13 is formed at tumble port 16
In, it is simple to rotating sheet 13 overturns down.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should
Within being included in protection domain of the present utility model.
