Description
Technical field
The utility model is related to technical field of sealing technology, more particularly to a kind of box body sealing structure.
Background technology
The sealing function of current driving force Battery case passes through control often by sealing ring is laid between case lid and casing
The decrement of sealing ring processed realizes sealing function, and the size of the decrement of sealing ring directly affects the close of electrokinetic cell casing
Seal reliability.
In order to solve the integrity problem of power battery box body sealing ring, need to make on the sealing ring of Battery case at present
Carried out with position-limit mechanism it is spacing, commonly used position limiting structure for inside sealing surface place one have certain altitude pad
Circle, controls the decrement of sealing ring by this method.Although this method can control the decrement of sealing ring, in peace
Assembly and disassembly process is easily dropped, it is necessary to limiting gasket is fixed using extra measure, adds cost.Simultaneously in electricity
When increasing packing ring at the position of the sealing ring of pond casing, if the material that case lid is used is the non-metallic materials such as composite, plastics
During material, position-limit mechanism and the direct small area contact of case lid easily make case lid bear larger in local place when assembling locking
Stress, subsequently using vibration processes, be easily caused case lid and be damaged (i.e. position of mounting hole is by conquassation or cracking), so that dynamic
There is potential safety hazard in power Battery case.
Utility model content
In view of problem present in background technology, the purpose of this utility model is to provide a kind of box body sealing structure, its
Installation and removal are convenient, during lock sealing, and it can avoid the first mounting hole of case lid cracking or first installs
Hole nearby by the problem of conquassation and case lid is because of the risk that local stress is excessive and damages, extends the life-span of case lid.
To achieve these goals, the utility model provides a kind of box body sealing structure, and it includes：Case lid, is provided with
Multiple first mounting holes；Casing, is assemblied in case lid；Sealing ring, is arranged between case lid and casing；Multiple fasteners, by case lid
With the connection of casing lock sealing；And press strip, positioned at the top of case lid.Wherein, press strip is provided with：Multiple 4th mounting holes；With
And multiple projections, respectively it is projected and formed in the position of corresponding 4th mounting hole and by the corresponding 4th mounting hole insertion, and
During lock sealing, in corresponding first mounting hole of each raised insertion case lid and by each fastener lock connection trim strip,
Case lid and casing.The beneficial effects of the utility model are as follows：
In box body sealing structure of the present utility model, fastener is directly squeezed when lock sealing connects case lid and casing
The press strip above case lid is pressed, so that case lid is not contacted directly with fastener, and then case lid is avoided because local stress is excessive
The risk of damage, extends the life-span of case lid.Simultaneously as each fastener via the 4th mounting hole of press strip through the of case lid
One mounting hole, thus avoid the first mounting hole during lock sealing near cracking or the first mounting hole by conquassation
Problem.Further, since each projection is in the first mounting hole during lock sealing, the position-limit mechanism with traditional sealing ring
Compare, be not in the situation that position-limit mechanism drops during installation and removal, so as to be conducive to the dress of box body sealing structure
Match somebody with somebody.

Embodiment
Describe in detail with reference to the accompanying drawings according to box body sealing structure of the present utility model.
Referring to figs. 1 to Fig. 9, included according to box body sealing structure of the present utility model：Case lid 1, is provided with multiple first peaces
Fill hole 11；Casing 2, is assemblied in case lid 1；Sealing ring 3, is arranged between case lid 1 and casing 2；Multiple fasteners 4, by the He of case lid 1
The lock sealing of casing 2 is connected；And press strip 5, positioned at the top of case lid 1.Wherein, press strip 5 is provided with：Multiple 4th mounting holes
51；And multiple raised 52, each raised 52 are formed at the position of corresponding 4th mounting hole 51 and by corresponding 4th installation
The insertion of hole 51, and during lock sealing, in corresponding first mounting hole 11 of each raised 52 insertion case lid 1 and by each tight
The locking of firmware 4 connection trim strip 5, case lid 1 and casing 2.
In box body sealing structure of the present utility model, fastener 4 is when lock sealing connects case lid 1 and casing 2, directly
The press strip 5 of the top of case lid 1 is extruded, so that case lid 1 is not contacted directly with fastener 4, and then case lid 1 is avoided because of local stress
It is excessive and damage risk, extend the life-span of case lid 1.Simultaneously as fourth mounting hole 51 of each fastener 4 via press strip 5
Through the first mounting hole 11 of case lid 1, so that it is cracking during lock sealing or first to avoid the first mounting hole 11
The problem of near mounting hole 11 by conquassation.Further, since each raised 52 are in the first mounting hole 11 during lock sealing
In, be not in position-limit mechanism during installation and removal compared with the position-limit mechanism (such as pad) of traditional sealing ring 3
Situation about dropping, so as to be conducive to the assembling of box body sealing structure.
According in box body sealing structure of the present utility model, referring to figs. 1 to Fig. 9, casing 2 is provided with multiple second and installed
Hole 21, sealing ring 3 is provided with multiple 3rd mounting holes 31.During lock sealing, each fastener 4 sequentially passes through corresponding
