Abstract
The utility model discloses a kind of novel battery cover cap to break opening structure, it is characterised in that：Include the positive pole ear being fitted in successively on battery steel shell, positive contact shell fragment, end face spring, positive terminal, positive contact shell fragment is pressed with the positive pole ear, the middle part of the positive contact shell fragment is provided with the groove to cave inward, and groove interior sealing has sealing mylar film, end face spring has been withheld on the sealing mylar film, positive terminal, and positive contact shell fragment, end face spring and the end face spring withheld successively by sealing ring encapsulation have been withheld on the end face spring.The utility model is reasonable in design, punctual breakdown action can be not only provided, so as to the air pressure inside timely balancing battery box hat, ensure the safety of battery, and battery cap break after return to normal condition, can both exclude the gases at high pressure of inside battery at any time, can cut off in time again both positive and negative polarity connection, reusing for battery can also be recovered, it may be said that be to achieve many things at one stroke.
Description
Technical field：
Battery cap structure is the utility model is related to, a kind of novel battery cover cap is related generally to and breaks opening structure.
Background technology：
Now in society, battery has been dissolved into the every nook and cranny of our lives closely, small to arrive battery of mobile phone, greatly to electronic vapour
Car electrokinetic cell, it may be said that battery is ubiquitous.Energy source of the electrokinetic cell as electric automobile, be electric automobile most
Main part.Therefore, the research and development of novel power battery technology and its safety are significant.
In the prior art, it is disposable that one side battery cap, which breaks structure, that is to say, that battery once breaks that
Battery is just forever scrapped, it is impossible to reuses；Another aspect battery cap opening structure differs surely to be opened on time, even and if opening
Open, battery is also forever to scrap, it is impossible to is reused.So battery does not only have certain potential safety hazard, while the meeting after unlatching
Substantial amounts of battery pollution is produced because of scrapping for battery, so as to aggravate the cost of battery recycling；And battery cap is broken
Structure is to break completion with aluminium strip, but he have a feedback slowly, break the time it is long the defects of, buried to battery safe hidden
Suffer from.
Utility model content：
The defects of the utility model purpose is exactly to make up prior art, there is provided a kind of novel battery cover cap breaks unlatching
Structure, when the short circuit a large amount of gases of generation occur for battery, the gases at high pressure of inside battery can be both excluded at any time, again can be timely
Both positive and negative polarity connection is cut off, reusing for battery can also be recovered, be killing three birds with one stone work(performance.
The utility model is achieved through the following technical solutions：
A kind of novel battery cover cap breaks opening structure, it is characterised in that：Include and be fitted in successively on battery steel shell
Positive pole ear, positive contact shell fragment, end face spring, positive terminal, positive contact shell fragment is pressed with the positive pole ear, it is described
The middle part of positive contact shell fragment is provided with the groove to cave inward, and groove interior sealing has sealing mylar film, the sealing mylar film
On withheld end face spring, withheld positive terminal on the end face spring, and the end face withheld successively by sealing ring encapsulation
On spring and positive contact shell fragment.
Pass through high viscosity sealant sealing between described sealing mylar film and positive contact shell fragment.
Described end face spring is an annular sheet metal, is coordinated with the positive contact shell fragment of sealing mylar film outer ring, described
The upper and lower end face of annular sheet metal is wavy shaped configuration, and it is provided with spaced groove and projection.
The utility model has the advantages that：
The utility model is reasonable in design, can not only provide punctual breakdown action, so as in timely balancing battery box hat
The air pressure in face, ensures the safety of battery, and battery cap break after return to normal condition, can both exclude inside battery at any time
Gases at high pressure, can cut off in time again both positive and negative polarity connection, reusing for battery can also be recovered, it may be said that be at one stroke it is more
.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial structurtes explosive view of the present utility model.
Cross-sectional view when Fig. 3 installs and uses for the utility model.
Embodiment：
Referring to accompanying drawing.
A kind of novel battery cover cap breaks opening structure, includes the positive pole ear being fitted in successively on battery steel shell 01
08th, positive contact shell fragment 06, end face spring 05, positive terminal 04, positive contact shell fragment 06 is pressed with the positive pole ear 08,
The middle part of the positive contact shell fragment 06 is provided with the groove to cave inward, and groove interior sealing has sealing mylar film 07, described close
End face spring 05 has been withheld on envelope mylar film 07, positive terminal 04 has been withheld on the end face spring 05, and pass through sealing ring 03
Encapsulate on the end face spring 05 and positive contact shell fragment 06 withheld successively.
Pass through high viscosity sealant sealing between described sealing mylar film 07 and positive contact shell fragment 06.
Described end face spring 05 is an annular sheet metal, is coordinated with the positive contact shell fragment of sealing mylar film outer ring, institute
The upper and lower end face for stating annular sheet metal is wavy shaped configuration, and it is provided with spaced groove and projection.
Connection is contacted by elastic pressure between described positive contact shell fragment 06 and positive pole ear 08, realizes that cathode circuit is led
It is logical.And seal wheat has high viscosity sealant sealing for peppery 07 between positive contact shell fragment 06, so as to ensure that gas inside battery core
The stability of pressure.
As described above, producing a large amount of gases when short circuit occurs for battery core 02, the pressure in battery steel shell 01 increases rapidly, battery
Positive contact shell fragment 06 in capping structure jacks up under the promotion of pressure, causes positive contact shell fragment 06 and positive pole pole upwards
Ear 08 separates the purpose for so as to realize that the cut-out details of circuit are shown in figure three, reaching and preventing battery core short circuit overcurrent from causing danger.
As described above, when battery core 02 produces a large amount of gases, the pressure in battery steel shell 01 increases rapidly, on battery cap
Positive contact shell fragment 06 jacks up under the promotion of pressure, causes positive contact shell fragment 06 to be separated with sealing ring 03, such steel upwards
Gases at high pressure in shell 01 discharge in the gap that contact flat spring 06 separates with sealing ring 03, so as to reduce in box hat 01
Air pressure, after the air pressure in box hat 01 reduces to a certain extent, the positive contact shell fragment 06 on battery cap is in end face spring 05
Elastic force under, move downward, promote positive contact shell fragment 06 and sealing ring 03 to be brought into close contact and realize the inner sealing of box hat 01, simultaneously
Contact during positive contact shell fragment 06 moves downward and with positive pole ear 08, so as to realize the conducting of battery core positive pole, such battery core is again
It can start to resume work.
