Specific embodiment
Preferred embodiments of the present invention are described below, those of ordinary skill in the art will be according to described below
It is realized with the relevant technologies of this field, and can be more clearly understood that the innovation and bring benefit of the utility model.
As shown in figures 1 to 6, a kind of ring structure, battery terminal post structure and battery cover for battery electrode column is provided
Plate.
The purpose of this utility model is achieved through the following technical solutions:
In a first aspect, providing a kind of ring structure for battery electrode column, the ring structure is arranged in battery cover
Insulation sealant is done between plate 3 and pole 2, the battery cover board 3 is provided with plastic structure under annular protrusion, the sealing ring 1
Including the sealing ring upper ring body 11 and sealing ring lower ring body 12 being connected as one, 12 inner end of sealing ring lower ring body is convex
Rising is the first sealing 121, and sealing ring lower ring body outer end protrusion is the second sealing 122, first sealing 121
A groove 123 is formed between the second sealing 122；
Wherein, an injection model, the sealing are being formed outside the pole between disk body, inner ring body 41 and outer ring body 42
Circle 1 is molded encapsulated molding using the injection model, makes sealing ring 1 and the connection of pole 2 closer by the way that injection molding is encapsulated, infuses
Modeling technique avoids sealing ring from assembling bring risk simultaneously, it is ensured that the consistency of sealing ring assembly.
Certainly, in some possible embodiments, the sealing ring upper ring body 11 is set as buckle structure, the pole 2
It is provided with outer disk body, the buckle structure is connect with the outer disk body snapping.
In a kind of possible embodiment, first sealing 121 is set as ramp structure, moulds under the annular protrusion
Plastic structure is set as ramp structure corresponding with the first sealing 121, and plastic structure insertion is described recessed under the annular protrusion
It in slot 123, squeezes and connects with the groove 123, the endpoint of the connection is the slope endpoint of the first sealing 121.It is logical
The extruding for crossing plastic structure and first sealing 121 under the annular protrusion connects, and forms primary sealing area conduct
First of seal line of anti-battery drain, two kinds of insulators of plastic structure and the sealing ring 1 under the annular protrusion
It is directly connected to down, so that the effect of the sealing ring is more preferable.
Further, plastic structure is ramp structure under the annular protrusion, reduces plastic cement knot under the annular protrusion
Structure squeezes the contact surface contacted with groove 123, and contact surface pressure increases, and sealing effect is substantially enhanced.
Further, the slope endpoint of first sealing 121 is set as arc, plastic cement knot under the annular protrusion
The slope endpoint of structure be set as with the slope endpoint arc of first sealing 121 be adapted arc, select arc be because
It is more than angular contact point for the contact point of arc, namely contact density height, so the sealing effect of arc contact connects than angular
The sealing effect of touching wants outstanding.
In the present embodiment, second sealing 122 is set as arc convex structure, second sealing 122 with
Metal portion 31, which squeezes, on the battery cover board connects.Utilize second sealing 122 and metal on the battery cover board
Portion 31 is press-connected the second line of seal to form secondary sealing area as anti-battery drain, will when cell internal pressure is excessive
Battery electrode column ejection, first of seal line at this time will leak, and second line of seal plays a role, and further prevents battery
Internal electrolyte leaks out, and under the defense reaction in twice defence line, further increases the effect of the sealing ring 1, the peace of battery
Full property is also guaranteed.
Further, first sealing 121, the second sealing 122 extruding exposure level all be squeeze the limit,
When the extruding limit, the groove 123 between first sealing 121 and the second sealing 122 disappears, and confined air is not present
Chamber.
In alternatively possible embodiment, it is convex that one sealing 121 of the ground with the second sealing 122 is both configured to arc
Structure is played, and all squeezes and connects with metal portion 31 on the battery cover board.Due to first sealing 121, described
Two sealings 122 are all press-connected with metal portion 31 on battery cover board, are formed the first, second sealing surface from inside to outside and are made respectively
For first, second line of seal for preventing battery drain, under the annular protrusion plastic structure will directly with 2 company of contact of pole
It connects, forms a kind of sealing structure of pseudo- three lines of defence.
Further, in the present embodiment, the bottom of the groove 123 is there are two types of shape, and one kind is flat shape, and another kind is
Arc.
123 bottom of groove between first sealing 121 and the second sealing 122 is the implementation of flat shape structure
In example, when squeezing the limit, the air in groove 123 is drained from, and the flat shape structure of 123 bottom of groove will be pressed down institute
It states to connect with the primary sealing area and the secondary sealing area and is combined into a big sealing surface, namely first of seal line
Width is more than the sum of the width of first of seal line, the width of second line of seal together with connecting into second line of seal
Total seal line, total seal line increases the contact density of the sealing ring 1 with the battery cover board 3, extends battery
The path of leakage improves the sealing effect of the sealing ring 1.
Further, when cell internal pressure increases, pole is risen, and the sealing effect of the first sealing 121 is corresponding
It will weaken, or even meeting electrolyte leakage, when first of seal line leaks, air enters groove 123,123 bottom of groove
The flat shape structure in portion restores to the original state, so that there are certain spaces for the groove 123, can accommodate a small amount of lysate, mitigate battery
Impact of the internal pressure to second line of seal, the lysate of leakage is blocked in second line of seal, prevents electrolyte from letting out
It drains to outside battery.
First sealing, 121 123 bottoms of groove the second sealing 122 between for arc concave shape structure again
In a kind of embodiment, the arc concave shape structure can be when squeezing the limit, can be in the primary sealing area and secondary sealing area
It prevents from forming a closed cavity between first of seal line of battery drain and second line of seal, the cavity is in addition to can
To accommodate outside extruding allowance, the electrolyte of leakage can also be accommodated after first leaks to defence line, improve the safety of battery
Property, mitigate pollution of the battery to environment.
Further, the metal portion on first sealing 121, second sealing 122 and the battery cover board
31 squeeze in contact process, and the air in the groove 123 is compressed in the arc concave shape structure of 123 bottom of groove,
Air pressure at this time in the arc concave shape structure of 123 bottom of groove is bigger；When the first seal line leaks a small amount of electrolyte,
A small amount of electrolyte can be released into first of seal line under the action of air pressure, increase that a kind of air pressure is anti-to let out mode, not only
Only the closing of sealing ring is anti-lets out mode.
Second aspect provides a kind of battery terminal post structure as shown in figures 2-6, and the battery terminal post structure is arranged in battery
In the pole providing holes 33 of cover board, the pole column structure includes pole 2, pole fixation kit 4 and is fixed at the pole
