Abstract
The utility model relates to a battery with an inflation protection structure, which comprises a battery, wherein a casing is covered outside the battery, a needle-shaped prick is arranged on the casing, the outer wall of the battery can be punctured through the needle-shaped prick when gas is formed inside the battery, the gas can be released, and the explosion caused by inflation of the battery is avoided.
Description
Technical field
The utility model relates to battery, says so exactly to have the battery of the protection structure that inside battery flatulence eliminates.
Background technology
In the use of battery, can run into the blast that two kinds of situations cause battery usually, the one, inside battery flatulence causes battery explosion; The 2nd, the outside big electric current of battery causes battery short circuit, causes battery explosion.
First kind of situation be because: battery is being manufactured in the process, the electricity core is difficult to reach 100% purity, and the impurity that electric core mixed can cause the electrolyte generation chemical reaction in the battery, produce gas, gas begins to make at least the battery surface protuberance, behind certain pressure of gas build, can break through the shell of battery, cause blast.
Therefore, people are in manufacturing the process of battery, pay attention to very much the quality of battery battery core, to control the generation of inside battery gas effectively, yet because battery battery core preparation technology's restriction can't reach the perfect purity of electric core, therefore more or less inside battery can produce gas, for fear of the drawback of inside battery gas, be necessary the structure of battery is improved.
Summary of the invention
Based on this, the purpose of this utility model provides a kind of battery with flatulence protection structure, and this battery can in time distribute the flatulence of inside battery, avoids battery explosion.
Another purpose of the present utility model provides a kind of battery with flatulence protection structure, and this battery structure is simple, be easy to realize.
In order to achieve the above object, the utility model is achieved in that
A kind of battery with flatulence protection structure; it comprises battery; it is characterized in that outside batteries is coated with housing; described housing is provided with the needle-like thorn; by the needle-like thorn, when inside battery forms gas, can puncture the outer wall of battery; gas release is come out, avoided battery because the blast that flatulence produced.
Described needle-like thorn, it has a plurality of, evenly is provided with and inner walls, to puncture at the battery outer wall effectively.
Described needle-like thorn, it is arranged at the middle part of described housing.
Because the gas that inside battery produced normally directly swells in the big outer wall of cell area, so, described needle-like thorn, it is arranged on the big inwall of two areas of battery container, and is inwardly outstanding, aims at the surface of battery.
Described needle-like thorn, its inside has the perforation that runs through, and after puncturing battery surface in this needle-like, the gas of inside battery can in time be discharged to the outside.
Described housing, its sidewall has a gas passage at least, so that after needle-like punctures battery surface, be convenient to gaseous emission to outside.
The battery structure that the utility model adopts makes battery can puncture battery surface when flatulence, discharges the gas that battery produced, thereby effectively battery is protected, and avoids because inside battery flatulence causes the blast of battery.
And that the utility model adopted was simple in structure, be easy to realize.
Description of drawings
The structural representation that Fig. 1 implements for the utility model.
Fig. 2 is the interior wall construction schematic diagram of battery case that the utility model is implemented.
Fig. 3 is the structure enlarged drawing of the described A part of Fig. 1.
Embodiment
Below, in conjunction with the accompanying drawings shown in, concrete enforcement of the present utility model is elaborated.
Shown in Figure 1, be the structural representation that the utility model is implemented, shown in the figure, battery 1 external packets is covered with housing 2, housing 2 is provided with needle-like thorn 3, by needle-like thorn 3, when inside battery formed gas, battery 1 surface can be swelled, when swelling when certain one-tenth is spent, needle-like thorn 3 can puncture the outer surface of battery 1, and gas release is come out, and has avoided battery because the blast that flatulence produced.
Needle-like thorn 3, operated by rotary motion is a plurality of, and is arranged at usually on the inwall on housing two big surfaces about in the of 2, to puncture at the battery outer surface effectively.
Shown in Figure 2, for each big surface of housing 2, it is 3 evenly distributed that needle-like is stung, and the middle part with housing 2 is set.
Simultaneously, as shown in Figure 3, needle-like thorn 3, its inside has the perforation 31 that runs through, and after puncturing battery surface in this needle-like thorn 3, the gas of inside battery can in time be discharged to housing 2 outsides.
In other execution mode, also can on housing 2, directly offer gas passage, to discharge the gas that inside battery flatulence is produced.
Therefore, by above-mentioned structure, the gas that is produced in the time of can discharging battery flatulence is effectively avoided battery because the battery explosion that inner flatulence caused.
The above; it only is a kind of specific implementation of the present utility model; do not represent and realize all implementations of the present utility model; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model; and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the protection range of the present utility model.
Claims (6)
1. one kind has the battery that flatulence is protected structure, and it comprises battery, it is characterized in that outside batteries is coated with housing, and described housing is provided with the needle-like thorn.
2. the battery with flatulence protection structure as claimed in claim 1 is characterized in that described needle-like thorn, and it has a plurality of, evenly is provided with and inner walls.
