Background technology
Low-carbon economy is the development trend of global economy, and China is also the positive advocate of low-carbon economy, and electric vehicle produces
Mainstay of the industry as low-carbon economy, potentiality are inestimable.The well-known growth consulting firm Frost＆Sullivan in the whole world recognizes
For following 10 years are that Chinese auto industry drives the critical period changed to electric drive power assembly from fossil fuel, are these
The major opportunity phase that native electric drive power assembly supplier faces.Dynamic lithium battery is the core of electric drive power assembly
Part, cost account for the 50%-70% of power assembly cost, dynamic lithium battery industry face during Chinese auto industry makes the transition
Face significant development opportunity.
Although dynamic lithium battery faces the opportunity of a lifetime, the research and development of current driving force lithium battery are manufactured also
There are many difficulties and defect, and manufacturing process is complicated, and yield is relatively low.There are electrode column poor sealing rates for current driving force lithium battery
Height, air-tightness is poor, and sealing material electrolyte resistance corrosive power is poor, and low temperature resistant limited (- 20 DEG C), winter cannot be in north etc.
The defects of low temp area uses, and region is poor for applicability.
Utility model content
The utility model is the defects of overcoming the prior art, and the utility model aim is to provide for a kind of sealing yield
Height, the good cover plate of power battery electrode column sealing device of air-tightness.
The technical solution adopted in the utility model is：Cover plate of power battery electrode column sealing device, including battery cover board sheet
Body, electrode column mounting hole and the seal in the electrode column mounting hole；The electrode column mounting hole upper end is provided with two
It is close to be equipped with a plurality of annular on the electrode column mounting hole lower face and positioned at the side of the electrode column mounting hole for a counterbore step surface
Seal wire casing；The seal include with centre bore sealed body and be separately positioned on sealed body upper and lower ends and with it is described
The integrally formed connection planar portions of sealed body；The connection planar portions outer diameter is more than the outer diameter of the sealed body；Positioned at
The top of connection planar portions below the sealed body is equipped with and the ring packing wire casing fitting projection structure；Positioned at described
Connection planar portions above sealed body are connected on the underlying counterbore step surface；Below the sealed body
Connection planar portions be clamped on the electrode column mounting hole lower face, the bulge-structure is clamped into the ring packing wire casing
It is interior.
Further improved as the utility model, the ring packing wire casing has two, and is arranged at intervals, section
In V-shape.
Further improved as the utility model, the connection planar portions below the sealed body are equipped with
Extension；The extending part is connected end in the battery cover board.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
The cover plate of power battery electrode column sealing device of the utility model, by battery cover board design make sealing structure without
The electrode pressing plate installation space on battery cover board need to be occupied, makes compact-sized, improves its thermal diffusivity, the structure design of sealed body
Make sealing accurate positioning, prevent assembling misplace, improve sealing stability and safety loading coefficient and leakproofness it is good.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is the structure diagram of the cover plate of power battery electrode column sealing device of the utility model；
In figure：1- battery cover board bodies；2- electrode column mounting holes；3- counterbore step surfaces；4- ring packing wire casings；5- is sealed
Body；Planar portions are connected on 6-；Planar portions are connected under 7-；8- bulge-structures；9- extensions.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figure 1, the cover plate of power battery electrode column sealing device of the utility model, including battery cover board body 1,
Electrode column mounting hole 2 and the seal in electrode column mounting hole 2；2 upper end of electrode column mounting hole, which is provided with, to be divided into
The two counterbore step surfaces 3 put are equipped with a ring on 2 lower face of electrode column mounting hole and positioned at the side of electrode column mounting hole 2
Shape seals wire casing 4.
Seal include with centre bore sealed body 5 and be separately positioned on 5 upper and lower ends of sealed body and with sealing
The integrally formed upper connection planar portions 6 of main body and lower connection planar portions 7；Upper and lower connection 6,7 outer diameter of planar portions is all higher than sealing master
The outer diameter of body 5.
It is equipped with and 4 fitting projection structure 8 of ring packing wire casing in the top of lower connection planar portions 7；In sealing assembling process
In, sealed body 5 is packed on 2 medial surface of electrode column mounting hole, and upper connection planar portions 6 are connected to underlying counterbore step surface
On 3, the bulge-structure 8 of lower connection planar portions 7 is clamped in ring packing wire casing 4, is made in assembling process, and sealing positioning is accurate
Really, installation deformation dislocation is prevented；Ring packing wire casing 4 has two, and is arranged at intervals, and section is in V-shape, promotes its sealing
Performance.
Uppermost counterbore step surface, makes seal be set with electrode platen gap, and seal is not straight with electrode pressing plate
Contact, perfect heat-dissipating so that sealed body will not generate the distortion of opposing seal body because of long-time stress
The phenomenon that, the sealing performance of seal has been effectively ensured, has avoided liquid leakage.
Lower connection planar portions 7 are equipped with extension 9；The setting of extension 9 adds contact of the seal with battery cover board
Area improves leakproofness.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
