Abstract
The utility model provides a battery explosion-proof cap comprising a cap head and a cap bottom. The cap head is provided with integrally formed explosion-proof holes which are sector holes in radial form, and the cap head is welded on the cap bottom. By adopting the scheme and a sector hole exhaust system of the three explosion-proof holes, section width of the cap is up to half of the circumference of an integral battery, thereby guaranteeing cap strength, enlarging an exhaust passage to the maximum extent and increasing safety of the battery.
Description
Technical field:
The utility model relates to the battery anti-explosion technical field, refers in particular to a kind of battery explosion-proof cap.
Background technology:
In recent years, to massaging device such as notebook-PC, mobile communications device such as portable phone, portable electron device such as video camera, digital camera, and the demand express delivery of portable audio device increases, and as the main power supply that is used for this electronic installation, closed compact battery such as NI-G, ni-mh and lithium ion battery owing to its high pressure, high-energy-density with and the every field that is used in light weight, along with the continuous development of battery, various battery production technology continues to bring out.Traditional battery cap generally has one to four stretchable holes or circular hole to be used for exhaust, but because battery capacity is more and more higher along with the progress of technology, in use, the incident of blasting soon inadequately owing to the battery exhaust happens occasionally, have influence on user's personal safety greatly, how to make the quick exhaust of battery become current main research topic.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of ventilating fast, battery explosion-proof cap that explosion-proof performance is good are provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of battery explosion-proof cap, and it includes headkerchief, the lid end, and headkerchief is provided with integrally formed explosionproof hole, and explosionproof hole is radial scallop hole, and headkerchief is welded on and covers at the end.
Described explosionproof hole is three, radially is evenly distributed in the corner of headkerchief bottom.
The cross-sectional width of described scallop hole exhaust is half of entire cell circumference.
The utility model is after having adopted such scheme, adopted the scallop hole gas extraction system of three explosionproof holes, its cross-sectional width reaches half of entire cell circumference, in the intensity that guarantees block, strengthen the exhaust passage to greatest extent, improved the fail safe of battery.
Description of drawings:
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model headkerchief vertical view.
Reference numeral: 1-headkerchief, the 2-lid end, 3-explosionproof hole.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing 1 and accompanying drawing 2, and preferred embodiment of the present utility model is: the described structure of present embodiment includes headkerchief 1, the lid end 2.Headkerchief 1 is provided with integrally formed explosionproof hole 3, explosionproof hole 3 is radial scallop hole, the cross-sectional width of scallop hole exhaust is half of entire cell circumference, when explosionproof hole 3 is scallop hole, can effectively accelerate the speed of exhaust, the explosionproof hole 3 of present embodiment is three, radially is evenly distributed in the corner of headkerchief 1 bottom.Headkerchief 1 is welded on and covers at the end 2.Adopt three explosionproof holes 3, in the intensity that has guaranteed battery cap, strengthened the exhaust passage to greatest extent, improved the fail safe of battery.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection range of the present utility model.
