The sealing block structure of battery provided by the utility model, for solving when there are multiple between conducting block and lamina tecti
During gap, the sealing effect of sealing structure can substantially reduce, and lead to the hydraulic performance decline of lithium battery, be unfavorable for using for lithium battery
Problem, also available in other kinds of battery, being not limited only to the present embodiment.
The sealing block structure of battery, including horizontally disposed sealing sheet body 11, the upper end of the sealing sheet body 11 is convex up
It rises, forms cricoid upper sealing ring 12, sealing ring 12, which surrounds, on this forms upper sealing area, upper close after sealing block assembles
The top of seal 12 is abutted with the bottom of coping plate；The post holes 14 passed through for conducting block, post holes 14 are provided on sealing sheet body 11
Upper end opening be formed in sealing area；The upper surface of sealing sheet body 11 is formed with sealing ring 13, and sealing ring 13 is arranged on
Arrange that, when sealing block is completed, the top of sealing ring 13 is pressed on coping plate in upper sealing area and around post holes 14
Bottom.
The sealing block structure of the battery of above-mentioned offer, should by forming sealing ring 12 in the upper surface of sealing sheet body 11
Upper sealing ring 12, which surrounds, forms upper sealing area, is set in upper sealing area and arranges sealing ring 13 around 14 periphery of post holes, when
For sealing block when installation is complete, the top of upper sealing ring 12 and sealing ring 13 is pressed on the bottom of coping plate, substantially in column
14 periphery of hole forms the effect of dual-seal, substantially increases the sealing performance of sealing block, solves when conducting block and lamina tecti
Between there are during multiple gaps, the sealing effect of sealing structure can substantially reduce, and lead to the hydraulic performance decline of lithium battery, be unfavorable for lithium
The problem of use of battery.
In the present embodiment, the lower end of sealing sheet body 11 convexes to form cricoid lower seal 15, lower seal 15 down
Encirclement forms lower sealed region domain, and after lithium battery is completed, the lower end of lower seal 15 is pressed on the pedestal of conducting block；
The lower ending opening of post holes 14 is formed in the domain of lower sealed region, and the gap between such post holes 14 and conducting block is in lower sealed region
In domain, gap of the lower seal 15 between post holes 14 and conducting block has Packed effect.
Specifically, lower seal 15 is arranged with upper 12 consistency from top to bottom of sealing ring, in this way, in lower seal 15 and upper sealing
When circle 12 is by ambient pressure, interaction force is generated between lower seal 15 and upper sealing ring 12 so that lower seal
15 occur positive deformation with upper sealing ring 12, and lower seal 15 is avoided to be deformed upon with upper sealing ring 12 towards side so that
The sealing effect of sealing block is more preferable.
