Abstract
The utility model discloses a battery core casing, and the outer surface of the battery core casing presents a cylindrical shape. The battery core casing mainly comprises a cylindrical surface, a covering cap and a bottom, wherein the surface of the battery core casing is provided with an explosion-proof mark. When in use, because the surface of the battery core casing is provided with the explosion-proof mark, a lithium battery core generates short circuit in the process of using, and temperature rise inside a casing generates lots of gases to cause that when a battery expands and explodes, explosion force breaks through along the direction of the explosion-proof mark; thus, the battery core casing is split to cause the explosion force to be released; as a consequence, the battery is avoided being exploded into pieces because the explosion force does not have a gap when the explosion of the battery occurs to avoid that a situation which has the threat for personal safety occurs. The utility model realizes the purpose of the explosion-proof function of the battery core casing.
Description
Technical field
The utility model relates to a kind of battery components and parts, refers to a kind of battery housing that can be applicable to cellular li-ion battery especially.
Background technology
At present, raising along with people's living standard, the application of mobile phone in people's life is more and more general, it becomes irreplaceable communication tool in people's life gradually, and battery is the important component part of mobile phone, used battery all is a lithium battery in the general mobile phone, but, because the lithium battery core may produce short circuit in the process of using, cause the interior temperature rising of housing and produce a large amount of gas, very easily make the cell expansion blast, if the battery surface of shell is not provided with explosion-proof trace, then in a single day battery blasts, then pulverizing that can battery is fried because explosive force does not have the breach, thus the person is constituted potential threat, therefore require the battery surface of shell to have explosion prevention function, and used in the market circular lithium battery, its battery surface of shell is not provided with explosion-proof trace, thereby does not have explosion prevention function.
The utility model content
The purpose of this utility model is to provide a kind of battery housing with explosion prevention function.
For achieving the above object, solution of the present utility model is: a kind of battery housing, and its outer surface is configured as cylinder, and it mainly includes a face of cylinder, block and bottom, and wherein: described battery surface of shell is provided with explosion-proof trace.
Described explosion-proof trace is located on the face of cylinder, block or the bottom of battery housing.
Described explosion-proof trace is configured as vertically, laterally or be crisscross arranged.
After adopting said structure, during use, because the surface of battery housing is provided with explosion-proof trace, so in the process that the lithium battery core is using, produce short circuit, temperature raises a large amount of gases of generation and makes the cell expansion explosion time in the housing, explosive force can be broken through along the direction of explosion-proof trace, the battery housing is split, explosive force is discharged, thereby avoided when battery is blasted, the pulverizing of battery being exploded because explosive force does not have the breach promptly takes place the situation that the person constitutes a threat to, and realizes making the battery housing have the purpose of explosion prevention function.
Description of drawings
Fig. 1 is embodiment one of the present utility model;
Fig. 2 is embodiment two of the present utility model;
Fig. 3 is embodiment three of the present utility model.
Embodiment
As shown in Figure 1, 2, 3, the utility model discloses a kind of battery housing, its outer surface is configured as cylindrical, and it mainly includes a face of cylinder 1, block 2 and bottom 3, wherein:
The described face of cylinder 1 is provided with explosion-proof trace 11, and explosion-proof trace 11 can be vertically, laterally or be crisscross arranged, in addition, because the maximum weighted direction of explosive force is the vertical of the face of cylinder 1, so explosion-proof trace is made as the vertical preferred forms that is.
It is explosion-proof 21 that described block 2 is provided with, and also is provided with explosion-proof trace (not shown) on the bottom 3.
During use, because the surface of battery housing is provided with explosion-proof trace, so in the process that the lithium battery core is using, produce short circuit, temperature raises a large amount of gases of generation and makes the cell expansion explosion time in the housing, explosive force can be broken through along the direction of explosion-proof trace, the battery housing is split, explosive force is discharged, thereby avoided when battery is blasted, the pulverizing of battery being exploded because explosive force does not have the breach, promptly the situation that the person constitutes a threat to is taken place, realize making the battery housing have the purpose of explosion prevention function.
Claims (4)
1, a kind of battery housing, its outer surface is configured as cylinder, and it mainly includes a face of cylinder, block and bottom, it is characterized in that: described battery surface of shell is provided with explosion-proof trace.
