Vibrated caused by road conditions, be likely to result in connecting portion and release, form Joint failure, or the formation electric discharge ablation between auxiliary connection,
Resistance increases；The flatness requirement of the latter's face of weld is high, and battery modules, battery bag assembling require strict, processing difficulties；
Utility model content
The purpose of this utility model is to provide a kind of Soft Roll bus structures, to solve what is proposed in above-mentioned background technology
Tightened by bolt and nut, be likely to result in connecting portion and release, form Joint failure, or electric discharge is formed between auxiliary connection and burnt
Lose, resistance increase etc. is tightened and high to the flatness requirement of face of weld by laser welding, battery modules, battery bag assembling
It is required that strict, processing difficulties problem.
To achieve the above object, the utility model provides following technical scheme：A kind of Soft Roll bus structures, including electricity
Core, the two ends of the battery core are installed with a fixed plate and No. two fixed plates respectively, and a fixed plate and No. two are consolidated
The outer surface of fixed board is also installed with framework, and the framework is hollow quadratic body structure, and wraps up battery core and a fixed plate
With the entirety of No. two fixed plate formation, the upper end of battery core is additionally provided with bus-bar, and the bus-bar is by metal connecting sheet and metal
Connector is constituted, and spot-welded is passed through between metal connecting sheet and metal connector.
It is used as further program of the utility model：Circular hole, circular hole and bolt spiral shell are further opened with the metal connector
Parent phase coincide.
It is used as further program of the utility model：The metal connecting sheet is made of copper strips.
Compared with prior art, the utility model beneficial effect：
Soft Roll bus structures of the present utility model, the connection that metal connecting sheet effectively eliminates shuttle belt releases, ftractureed
Equivalent risk；And because metal connecting sheet is made of copper strips, good toughness, elastic deformation amount is big, can greatly reduce and assemble
For the requirement of battery core pole flatness in journey.Even if being uneven after battery core assembling, assembling is not still influenceed；And this practicality
New Soft Roll bus structures, part preparation technology is ripe metal working process, it is easy to which quick application, batch are raw
Production, reliability are high, with low cost, and can pass through visible welding inspection welding quality.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clear, complete description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1-3, the utility model embodiment, a kind of Soft Roll bus structures, including battery core 1, the battery core 1
Two ends be installed with a fixed plate 2 and No. two fixed plates 3 respectively, a fixed plate 2 and No. two fixed plates 3 it is outer
Surface is also installed with framework 4, and the framework 4 is hollow quadratic body structure, and wraps up battery core 1 and a fixed plate 2 and two
The entirety of number fixed plate 3 formation, the upper end of battery core 1 is additionally provided with bus-bar 5, and the bus-bar 5 is by metal connecting sheet 6 and metal
Connector 7 is constituted, and metal connecting sheet 6 is made of copper strips, and copper strips good toughness, elastic deformation amount can have greatly in an assembling process
Effect reduction is for battery core pole planarity requirements after assembling, by spot-welded between metal connecting sheet 6 and metal connector 7,
Circular hole 71 is further opened with metal connector 7, circular hole 71 matches with bolt and nut, with satisfaction nut by fastening means with
The application places of pole connection.
Soft Roll bus structures of the present utility model, the connection that metal connecting sheet 6 effectively eliminates shuttle belt releases, ftractureed
Equivalent risk；And because metal connecting sheet 6 is made of copper strips, good toughness, elastic deformation amount is big, can greatly reduce and assemble
For the requirement of battery core pole flatness in journey.Even if being uneven after battery core assembling, assembling is not still influenceed；And this practicality
