Abstract

The invention discloses a battery anti-explosion system, mainly aiming to optimally select the design of sealing ring materials and cover caps, and polypropylene materials are selected to manufacture sealing rings from the various traditional plastic materials. The polypropylene materials are softened or partially melted at the high temperature of 80-100 DEG C, a gap appears between the steel shell of a battery and the cover cap of the battery so as to release the inner gas of the battery, the inner pressure of the battery is reduced, and the explosion of the battery is prevented.

Description

Battery anti-explosion system
Technical field
The present invention relates to a kind of battery anti-explosion system.
Background technology
Along with the fast development of electronic digital product, the performance requirement of supporting battery product is improved constantly.Not only there is requirement existing market to the traditional performance such as battery capacity, life-span, more pays attention to the security performance of battery.The appearance of sealed cell makes the scope of application of battery open up widely extensively, but the direction that the Dou Shige battery producer effort all the time of the security performance of sealed cell improves.As shown in Figure 1, Figure 2, Figure 3, Figure 4, current battery manufacture commercial city uses the sealing ring 1 of nylon-66 and common block 2 to be combined into the explosion-protection equipment of sealed cell, explosion-proof ball 3 in common block 2.Because sealing ring 1 fusing point of nylon-66 is higher, rigidity is very large and common block 2 opening pressure range stabilises is at high temperature high, this kind of battery is after being short-circuited, promptly can not drain the gas that inside battery produces, interior pressure increases rapidly, battery temperature raises fast, and battery will be blasted.If battery occurs short circuit in transportation, the heat of generation can not distribute in time, causes chain reaction to cause more battery to be short-circuited phenomenon, serious overall explosion accident will occur, burn ship or vehicle.And in client's use procedure, there is short circuit, electronic digital product can be caused damage, such as, burn out, blast, on fire etc., serious even causes personal safety.
Summary of the invention
The object of the present invention is to provide a kind of battery anti-explosion system, it is at battery short circuit, effectively inside battery gas can be drained in time time temperature raises, inner pressure of battery is reduced, thus the problem can blasted after the short circuit that occurs of sound solution battery.
In order to achieve the above object, the present invention is realized by following technical scheme.
A kind of battery anti-explosion system, the design mainly for sealing ring material and block is in optimized selection, in existing multiple plastic material, select polypropylene material to be made into sealing ring.This polypropylene material can soften under the hot conditions of 80 DEG C-100 DEG C or fusing appears in part, makes to occur gap between battery steel shell and block, and inside battery gas is discharged, and inner pressure of battery reduces, and stops battery to occur blast.In the design of block, select the rubber that can lose efficacy under the high temperature conditions as the material of explosion-proof ball.Battery is under certain hot conditions, and because explosion-proof ball lost efficacy or partial failure, block pressure is reduced, and be vented, inner pressure of battery reduces, thus stops battery to occur blast.
Beneficial effect of the present invention is, the Combination application of the application of the invention sealing ring and block is on battery, this is combined in battery short circuit, effectively inside battery gas can be drained in time time temperature raises, inner pressure of battery is reduced, thus the problem can blasted after the short circuit that occurs of sound solution battery.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
A kind of battery anti-explosion system as shown in Figures 5 to 9, the explosion-proof ball 6 mainly comprising sealing ring 4, block 5 and be located in block 5, the present invention is in optimized selection mainly for the design of sealing ring 4 material and block 5, selects polypropylene material to be made into sealing ring 4 in existing multiple plastic material.This polypropylene material can soften under the hot conditions of 80 DEG C-100 DEG C or fusing appears in part, makes to occur gap between battery steel shell and block, and inside battery gas is discharged, and inner pressure of battery reduces, and stops battery to occur blast.In the design of block 5, select the rubber that can lose efficacy under the high temperature conditions as the material of explosion-proof ball 6.Battery, under certain hot conditions, because explosion-proof ball 6 lost efficacy or partial failure, makes block 5 pressure reduce, is vented, and inner pressure of battery reduces, thus stops battery to occur blast.

Claims (1)

1. one kind prevents the method for battery explosion, the method mainly comprising sealing ring by using, blocking a shot and be located at the battery anti-explosion system of the explosion-proof ball in block and realize, it is characterized in that, first, select polypropylene material to make sealing ring, this polypropylene material can soften under the hot conditions of 80 DEG C-100 DEG C or fusing appears in part, make to occur gap between battery steel shell and block, inside battery gas is discharged, and inner pressure of battery reduces, thus stops battery to occur blast; Secondly, select the rubber lost efficacy under the high temperature conditions as explosion-proof ball material, battery is under this hot conditions, and because explosion-proof ball lost efficacy or partial failure, block pressure is reduced, and be vented, inner pressure of battery reduces, thus stops battery to occur blast.
