It is bright and simplify description, rather than instruction or imply that signified device or element must have specific orientation, with specific orientation
Construction and operation, therefore be not considered as limiting the invention.
In the description of the present invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
To be mechanical connection or be electrically connected；It can be directly connected, can also be indirectly connected by intermediary, Ke Yishi
Connection inside two elements.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this
Concrete meaning in invention.
As Figure 1-Figure 4, the present invention provides a kind of battery pack seal configuration, including upper cover 1, gasket 3 and lower cover
2, the gasket 3 is folded between the upper cover 1 and the lower cover 2, and the upper cover 1 and the lower cover 2 pass through the sealing
The closing of pad 3 connects, and equally distributed bulge-structure is provided with the gasket 3, and the bulge-structure is solid with the gasket 3
Fixed connection or integrally formed.In this way, equally distributed bulge-structure is provided with gasket 3, after upper cover 1 and lower cover 2 press,
Bulge-structure on gasket 3, which suffers oppression, to be deformed upon, at the bulge-structure position of deformation, upper cover 1 and the leakproofness of lower cover 2
It is more superior, and bulge-structure is uniformly distributed setting, and the sealing of upper cover 1 and lower cover 2 in whole sealing surface is effectively ensured
Property can be guaranteed.This have the advantage that in terms of existing technologies：Simple in structure, versatility is good, and bearing capacity is good,
Resistance wear resistance is strong, and sealing effect is good, can preferably ensure the sealing effect of battery pack, so as to ensure the sealing peace of battery pack
Quan Xing.
The battery pack seal configuration of the present invention, as Figure 1-Figure 4, on the basis of previously described technical solution also
Can be：At least two rows of bulge-structures are provided with the gasket 3.In this way, being provided with least two rows of bulge-structures, increase
Add upper cover 1 with lower cover 2 in pressing, gasket 3 deforms upon the quantity of position, further enhances the sealing effect of gasket 3
Fruit.Further preferred technical solution is：3 both sides of gasket are both provided with bulge-structure.In this way, gasket 3 is in direction
Upper cover 1 and lower cover 2 are respectively provided with bulge-structure, are further ensured that sealing effect during pressing.Further preferred technical solution is：
Often arranging the bulge-structure includes the consistent protrusion 4 of gap size, any one protrusion 4 on a row is arranged at another row's phase
On the perpendicular bisector of corresponding two neighboring raised 4 line.In this way, to be arranged at another row opposite for any one protrusion 4 on row
