This utility model is achieved in that
A kind of battery container, including enclosure body, described enclosure body outer wall is provided with some explosion-proof lines, described enclosure body
Inwall is provided with some inner groovies, corresponding with described explosion-proof line position bottom described inner groovy.
Further, described explosion-proof line is axially extending along described enclosure body, and described inner groovy is also along described housing originally
Body axially extending.
Further, described explosion-proof line is that its two ends are also distinguished along the axially extended longitudinal explosion-proof line of described enclosure body
Connect and have horizontal explosion-proof line.
Further, the region that described longitudinal explosion-proof line and horizontal explosion-proof line surround forms the first appearance to enclosure body indent
Receiving space, described first accommodates in space and is provided with Heat Conduction Material.
Further, on the radial section of described enclosure body, described first accommodates the degree of depth in space from neighbouring described
One end of longitudinal explosion-proof line is gradually increased to the other end.
Further, described enclosure body bottom outside is provided with some bottoms explosion-proof line, described enclosure body bottom inside
Being provided with some bottom recesses, described bottom explosion-proof line is corresponding with described bottom recesses bottom position.
Further, described enclosure body bottom centre be provided with newel, described bottom explosion-proof line and bottom recesses around
Described newel annular is arranged.
Further, described bottom explosion-proof line is curved, and two ends are connected to the edge bottom described enclosure body, described
Region in the explosion-proof line of bottom indent bottom enclosure body forms the second receiving space, is provided with and leads in described second receiving space
Hot material.
Further, on the axial cross section of described enclosure body, described second accommodates the degree of depth in space from neighbouring described
One end of bottom explosion-proof line is gradually increased to the other end.
A kind of battery, including battery core and cover plate, described battery also includes that above-mentioned battery container, described battery core are positioned at described electricity
In the housing of pond, described cover plate lid is located at described battery container top.
Compared with prior art, this utility model has the advantage that
When the reasons such as this internal appearance short circuit of battery container produce a large amount of gas, the inner groovy of enclosure body can guide
The distribution of air pressure, assembles a large amount of gases at inner groovy, and explosion-proof line just position bottom inner groovy, and this position is pressure
Weak, when gas pressure is sufficiently large, explosion-proof line splits, and is exhausted, and inner groovy and explosion-proof line match so that explosion-proof line is opened
Accurately, efficiently.This housing can discharge gases at high pressure quickly, in large quantities, makes explosion condition to meet, and stops blast, improves
The security performance of battery.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.
As shown in Figure 1 to Figure 3, for this utility model one preferred embodiment, a kind of battery container, including enclosure body 1, shell
Body body 1 outer wall is provided with some explosion-proof lines, and enclosure body 1 inwall is provided with some inner groovies 3, with explosion-proof line position bottom inner groovy 3
Put corresponding.
Specifically, in globoidal structure bottom inner groovy 3, explosion-proof line is axially extending along enclosure body 1, inner groovy 3 also edge
Enclosure body 1 axially extending.Explosion-proof line is along the axially extended longitudinal explosion-proof line 2 of enclosure body 1, and its two ends have been also respectively connected with
Laterally explosion-proof line 4, uses three sections of explosion-proof line designs so that one section does not has explosion-proof line, and do not have explosion-proof line plays support edge
Effect so that explosion-proof line will not be gone out after being backed down, and prevents accidental injury personnel, and the unlatching pressure of explosion-proof line can be arranged more than block
Unlatching pressure.The region that longitudinal explosion-proof line 2 and horizontal explosion-proof line 4 surround forms the first receiving space to enclosure body 1 indent
5, the first receiving space 5 is provided with Heat Conduction Material, Heat Conduction Material can select heat conductive silica gel or heat-conducting silicone grease, accelerates dissipating of battery
The thermal efficiency, improves safety and the life-span of battery, can also protect receiving space simultaneously, play a cushioning effect, outside preventing
Power is damaged.On the radial section of enclosure body 1, first accommodates the degree of depth in space 5 from one end of neighbouring longitudinal explosion-proof line 2 to separately
One end is gradually increased.
