Abstract
The utility model provides a kind of battery module, different and cause the problem of lug is pulled out or pulled loose in bus-bar to solve bus-bar and battery core vibration generation time.The battery module includes bus-bar and at least two battery cores, the electrode of the battery core is connected by lug with bus-bar, lug has the bus-bar connection end being connected with bus-bar and the battery core connection end being connected with battery core, and lug also has the elastic buffer section for being used to prevent transmitting forces between bus-bar linkage section and battery core linkage section.When bus-bar is different with battery core vibration generation time, both occur relative motion, due to the flexible breeze way of lug, elastic buffer section can be straightened, avoid transmitting forces between the bus-bar connection end of lug and battery core connection end and make lug two ends stress cause lug to pull out or pull loose in bus-bar, even result in lug and directly fracture.
Description
Technical field
The utility model is related to a kind of battery module.
Background technology
Support energetically with country to new energy industry, power battery technology is continued to develop, especially nearly 2 years lithiums
The outburst of battery blowout, lithium electricity product is commercially seen everywhere.Soft package lithium battery is special structural due to its, relative to
The installation such as cylinder, duricrust battery are higher.But soft package lithium battery also has the inferior position of their own, such as the fragility of lug is existing
Often cell polar ear is fixed on the bus-bar of pinboard by laser welding or screw in some soft package lithium battery modules.But
Be the working environment of soft package lithium battery module be not often the battery module on a static environment, such as electric automobile work
Environment is with regard to rather harsh, and when electric automobile passes through crankcase ventilaton, battery module generation is larger to jolt, because battery core is to pass through
Cell polar ear directly welding or screw are fixed on change-over panel, while lug is also without buffering area.When whole battery module shakes
When dynamic, change-over panel（Bus-bar）It is different with the vibration generation time of battery core, relative motion is produced between bus-bar and battery core, is confluxed
Active force can be transferred in battery core by row by lug, can cause lug by the pulling force effect of bus-bar, prolonged work
Afterwards, lug may be pulled out or produced loosening in bus-bar or even lug can be made directly to fracture, battery module is produced
Fatal influence, while also causing very big potential safety hazard to user.
Utility model content
The purpose of this utility model is to provide a kind of battery module, to solve bus-bar and battery core vibration generation time not
Cause the problem of lug is pulled out or pulled loose in bus-bar together.
To achieve the above object, the technical scheme of the utility model battery module is：A kind of battery module, including bus-bar
With at least two battery cores, the electrode of the battery core is connected by lug with bus-bar, and lug has what is be connected with bus-bar to conflux
Row connection end and the battery core connection end that be connected with battery core, lug also have for prevent bus-bar linkage section and battery core linkage section it
Between transmitting forces elastic buffer section.
The elastic buffer section is by lug itself bending.
The elastic buffer section is semicircular structure.
Elastic buffer section is located at the downside of bus-bar.
Bus-bar is perforated provided with lug, and lug has the transverse direction that bus-bar upper surface is attached at through after lug perforation
Connection is while vertical in lug perforation practices level.
The beneficial effects of the utility model are：When bus-bar is different with battery core vibration generation time, both occur relatively
Motion, due to the flexible breeze way of lug, elastic buffer section can be straightened, it is to avoid the bus-bar connection end of lug and
Transmitting forces between battery core connection end and make lug two ends stress cause lug to pull out or pull loose in bus-bar, even result in
Lug directly fractures.
Elastic buffer section is located at the downside of bus-bar, and the amplitude of elastic buffer section bending can be made bigger, make elastic buffer
The absorbent active force of section institute is more.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model battery module embodiment；
Fig. 2 is the schematic diagram of battery in the utility model battery module embodiment.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of battery module of the present utility model, as shown in Figure 1 to Figure 2, wherein, 1 is battery core, and 2 be conversion
Plate, 3 be change-over panel inner copper line, and 4 be lug, and lug 4 includes bus-bar linkage section 5, vertical section 6 and battery core linkage section 7, vertical section
There is bending buffer structure 8 on 6.
In the present embodiment, change-over panel 2 and change-over panel inner copper line 3 constitute bus-bar, are perforated on the busbar provided with lug.
Lug 4 includes bus-bar linkage section 5, vertical section 6 and battery core linkage section 7, and battery core linkage section 7 is fixedly connected with battery core 1, and battery core connects
Connect space of the section 7 inside battery core；Bus-bar linkage section 5 is fixed on the busbar, and fixed form can be for welding either
Mode connects for screw.In the present embodiment, bus-bar linkage section 5 include be upward through the lug of bus-bar perforation after bending and be adjacent to converge
Flow row upper surface lateral connection while and positioned at lug perforation in vertical connection while.In bus-bar linkage section 5 and battery core
Between linkage section 7 for vertical section 6, vertical section 6 is provided with bending buffer structure 8, and bending buffer structure 8 is the vertical section of lug
6 to side bending, during processing, and directly lug, which is applied, with other force application objects can make the formation bending of vertical section 6
Buffer structure 8.In the present embodiment, bending buffer structure 8 is semicircular structure, and semicircular structure can increase the perpendicular of lug
The length being bent to section 6.Vertical section 6 is located at the downside of bus-bar, that is, bends the downside that buffer structure 8 is located at bus-bar, keep away
When having exempted from bending buffer structure 8 in lug perforation, the bending degree of bending buffer structure 8 is smaller and makes bending buffer structure institute
The active force that can be buffered diminishes.
Battery module of the present utility model when in use, when battery core is different with the time that bus-bar produces vibration, confluxes
Row and battery core produce pulling force to lug, now, and bending buffer structure 8 is bent buffer structure 8 and drawn by the pulling force effect at two ends
Straight certain degree offsets the effect of pulling force, prevents the bus-bar linkage section of lug from active force is transferred into battery core linkage section
On, lug is firmly connected with bus-bar and battery core, be pulled off while it also avoid lug.
In the present embodiment, during the lower end of battery core linkage section 7 is battery core connection end, the present embodiment, it is illustrated that bus-bar connects in 1
The left end for connecing lateral connection side in section 5 is bus-bar connection end.
In other embodiments, the shape and quantity of bending buffer structure can be changed according to actual conditions, such as curved
It can be triangle etc. to roll over buffer structure.In other embodiments, bending buffer structure can be the soft company being connected on lug
Contact pin.
In the present embodiment, bending buffer structure is elastic buffer section.
