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 enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is 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. 1～4, for the preferred embodiment of this utility model offer.
Rotating sheet 13 and the integrated battery cap of cover plate 11 1 that the present embodiment provides, is used in the cover plate of lithium battery
On 11, certainly, its utilization is not limited to lithium battery, it is also possible to be in other various batteries, as rechargeable battery etc..
Rotating sheet 13 and the integrated battery cap of cover plate 11 1 include cover plate 11 and rotating sheet 13, wherein, cover plate 11
And rotating sheet 13 is formed in one, in the form of sheets, rotating sheet 13 is formed in cover plate 11 cover plate 11.
In actual use, rotating sheet 13 battery cap integrated with cover plate 11 1 is arranged on housing upper of battery
End opening, say, that cover plate 11 is sealed on the upper end open of housing, so, when the pressure in battery increases, namely housing
Interior pressure increases, and when pressure is more than certain value, generally, the setting value of pressure is 0.5MPa, and rotating sheet 13 then can
Overturn upward so that the positive pole of battery and negative pole short circuit, it is to avoid the pressure in housing continues to increase.
Rotating sheet 13 and the integrated battery cap of cover plate 11 1 of above-mentioned offer, rotating sheet 13 is molded in cover plate 11,
And cover plate 11 and rotating sheet 13 are integrated, so, then need not separately independent manufacture molding cover plate 11 and rotating sheet 13,
It is greatly saved manufacturing cost, and for battery cap 1, does not haves the process that cover plate 11 mutually assembles with rupture disk 12,
Simplify the assembling of battery cap 1.
In the present embodiment, rotating sheet 13 and the integrated battery cap of cover plate 11 1 also include rupture disk 12, rupture disk shape
Become in cover plate 11, and rupture disk 12 and rotating sheet 13 are arranged separately.So, when the effect of rotating sheet 13 was lost efficacy, or
When pressure in housing persistently increases, when pressure is more than certain value, generally, the setting value of pressure is 0.8MPa, quick-fried
Fragmentation 12 explosion the most under the effect of the pressure, the pressure in housing then can leak, to avoid whole battery explosion.
Specifically, rupture disk 12 can be one-body molded with cover plate 11, it is also possible to after being independent molding, then is welded on cover plate 11
In, depending on being the most visually actually needed.
In the present embodiment, cover plate 11 is formed with blast hole 111 and tumble port 112, blast hole 111 and tumble port 112
Arranging separately, rupture disk 12 is formed in blast hole 111, and encloses blast hole 111, and rotating sheet 13 is formed at tumble port
In 112, and enclose tumble port 112.By rupture disk 12 and rotating sheet 13 are correspondingly arranged at blast hole 111 respectively and turn over
Turning in hole 112, when the pressure in housing increases, the beneficially air pressure in housing is concentrated and is acted on rupture disk 12 and upset
On sheet 13, it is greatly enhanced rupture disk 12 and the reaction sensitivity of rotating sheet 13 and precision.
In the present embodiment, the middle part of rotating sheet 13 is the most projecting, in ledge in the middle part of formation, and rotating sheet 13
The upper end of portion's ledge is provided with abutting post 133, and so, when the pressure in housing increases to certain value, air pressure is made
Being used on whole rotating sheet 13, rotating sheet 13 arches upward upward so that abuts post 133 and connects with electrode, it is achieved the positive pole of battery with
Negative pole short circuit.
Specifically, the periphery of rotating sheet 13 is formed on the sidewall of tumble port 112, and the sidewall of rotating sheet 13 is downwardly inclined
Arranging, form sloped sidewall 132, sloped sidewall 132 meets at middle part ledge, so, under the pressure of air, is conducive to
Rotating sheet 13 overturns upward.
For the ease of abutting the setting of post 133, the middle part ledge of rotating sheet 13 is that horizontal plate is arranged, certainly, according to
Being actually needed, middle part ledge can also be that other various shapes are arranged.It addition, abut upper end and the cover plate 11 of post 133
Upper surface flush arrangement, when rotating sheet 13 does not overturns, it is to avoid abuts post 133 and abuts with outside.
It addition, one-body molded for the ease of between rotating sheet 13 and cover plate 11, the periphery of rotating sheet 13 is formed with level
The connection ring 131 that shape is arranged, this connection ring 131 is connected on the sidewall of tumble port 112；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
The thickness of periphery is the thinnest.
In the present embodiment, the rounded shape of tumble port 112, so, in rotating sheet 13 is formed at tumble port 112, it is simple to turn over
Rotor 13 overturns down.
In the present embodiment, blast hole 111 and rupture disk 12 are in ellipticity, and certainly, blast hole 111 and rupture disk 12 can also
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 can be in multiple shape
Shape is arranged.
Rupture disk 12 is arranged on the bottom of blast hole 111, and the lower surface of rupture disk 12 is concordant with the lower surface of cover plate 11
Arranging, so, upper opening, and the explosion recess hole with rupture disk 12 as bottom are then formed at the top of blast hole 111, work as housing
When interior pressure increases, beneficially rupture disk 12 explosion upward.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
