Specific embodiment
In conjunction with the preferred embodiment, to the specific embodiment provided according to the present invention, details are as follows:
It is detailed in attached drawing 1, present embodiments provides a kind of pole convex type battery cover board, including battery cover board ontology 1, anode
External polar plate 2, positive insulating gum cover 3, positive sealing ring 4, positive rivet 5, positive strap 6, cathode external polar plate 7, negative insulation
Gum cover 8, cathode sealing ring 9, cathode rivet 10, negative straps 11 and Upper gasket 12, battery cover board ontology both ends part
Not She You outwardly convex hole slot, be equipped with the positive strap of bending or negative straps into hole slot respectively in hole slot, anode
Connection sheet, negative straps are separately connected positive and negative tab, and the anode external polar plate 2 passes through positive rivet 5 and positive insulating gum cover 3
Riveted is affixed, and cathode external polar plate 7 is affixed by cathode rivet 10 and 8 riveted of negative insulation gum cover, positive and negative rivet and battery cover board
The Upper gasket 12 of insulation is equipped between ontology, positive sealing ring and cathode sealing ring are respectively placed in above positive and negative electrode connection sheet.
The Upper gasket uses the plastic injection with preferable insulating properties and corrosion resistance to form.The Upper gasket surface is set
There is the small bulge of several protrusions, Upper gasket is fastened on battery cover board ontology.
Production and principle
Battery cover board is that battery cover board ontology puts fluorubber well on liquid injection hole, by the difference riveting of positive and negative anodes rivet in positive and negative anodes
On external polar plate, Upper gasket is placed between rivet and battery cover board ontology and is insulated, wherein positive and negative anodes rivet is mentioned using mold
Before accomplish fluently, Upper gasket insulating properties and the preferable plastic injection of corrosion resistance form, and Upper gasket plays important insulating effect,
Upper gasket needs to agree with shape onto cover board, also to there is the small bulge of protrusion, and it is stronger to increase frictional contact.Then it utilizes
Positive rivet 5 rivets together positive external polar plate 2, positive insulating gum cover 3, and cathode rivet 10 is exhausted by cathode external polar plate 7, cathode
Edge gum cover 3 rivets together.Battery completes positive pole ear and positive strap 6 and the cathode pole of pole group in assembling process
The ultrasonic welding of ear and negative straps 11, need thereafter in automatic wire body carry out connection sheet bending, battery cover board ontology 1 to
Upper punching, positive strap 6 and negative straps 11 can be bent into the upward hole slot of battery cover board ontology 1.
When carrying out PACK to single battery core, due to the volumetric constraint of car body, PACK mould group can be caused to limit.But pole
The height of column has what can be relaxed to utilize space.Battery core is by downward jet-bedding, connection sheet at battery cover board ontology pole at present
Bending can occupy pole group space.Design key of the invention is rationally to apply the height space of pole, i.e. cover board body
Outwardly convex at pole, space required for connection sheet is bent are placed in outside protrusion, and the bending space of connection sheet is turned
The space for turning to pole group height, the lower part from the bottom of Upper gasket to battery case are theoretical pole group space, the present invention
Cover board can make full use of theoretical pole group space with 100%, then the specific energy of battery core will be made to improve, reduce battery core capacity
Pressure, can not only be more concerned about other performances of battery core, but also improve the assembling of battery core, and reduce bulging and internal resistance.
Cover board assembly technology of the invention is fairly simple, and the use in later period is also easier, and present invention could apply to phosphorus
All kinds of lithium ion batteries such as sour iron lithium and ternary material.
It is above-mentioned referring to embodiment to a kind of detailed description of pole convex type battery cover board ontology, be it is illustrative without
It is restrictive, several embodiments can be enumerated according to limited range, therefore in the case where not departing from present general inventive concept
Change and modification should belong within protection scope of the present invention.
