Specific embodiment
It should be noted that in the absence of conflict, the spy in embodiment and embodiment in the utility model
Sign can be combined with each other.
The utility model is described in detail below with reference to the accompanying drawings and in conjunction with embodiment.
Structure referring to fig. 1 and fig. 2, the battery modules connection of the utility model include 1 He of the first copper bar with copper bar
Second copper bar 2, wherein one end of the first copper bar 1 is connected with one end of the second copper bar 2 to form linkage section 3, the thickness of linkage section 3
Degree is equal to or less than the thickness for the copper bar that thickness is thicker in the first copper bar 1 and the second copper bar 2.
In the battery modules connection copper bar, due to the thickness etc. of linkage section 3 between the first copper bar 1 and the second copper bar 2
In or less than in the first copper bar 1 and the second copper bar 2 thickness of the thicker copper bar of thickness therefore connected using such copper bar
When battery modules, influence that can be blocked up and to arrangement space to avoid the thickness of linkage section 3 promotes electricity in favor of copper bar cabling
Wrap the aesthetics of internal cabling arrangement in pond.
One end of first copper bar 1 is connected with one end of the second copper bar 2 can be by diversified forms come shape to form linkage section 3
At for example, an end face of an end face of the first copper bar 1 and the second copper bar 2 can be connected to each other and then be surrounded in a kind of form
Butt seam carries out laser welding to form linkage section 3, in this way, the thickness for the linkage section 3 that docking is formed can't be more than first
The thickness of the thicker copper bar of thickness in copper bar 1 and the second copper bar 2；Or in another form, the thickness of one end of the first copper bar 1
Half is reduced, the thickness of one end of the second copper bar 2 reduces half, then by the mutual overlap joint welding in one end of two copper bars, in this way,
Thickness after one end that two thickness reduce half overlaps also can be reduced correspondingly, for example, the thickness in two copper bars is identical
Under situation, the thickness of linkage section is just equal to the thickness of any one copper bar.
For example, the first copper bar 1, the second copper bar 2 are identical with the thickness of linkage section 3 in a kind of embodiment, in this way, connection
Copper bar track thickness afterwards is uniform, is routed in battery pack housing according to specific requirements convenient for copper bar, improves the beauty of wiring
The property seen.
Certainly, as described above, connect with one end of the second copper bar 2 can be with to form linkage section 3 for one end of the first copper bar 1
It is formed by diversified forms.For example, in more preferred mode, with reference to Fig. 1 and shown in Fig. 2, the one of the first copper bar 1
End and one end of the second copper bar 2 are respectively formed with mutually matched clamping structure to form linkage section, in this way, relative to the above institute
For the mode for the end face docking stated, by clamping structure, it is not only convenient for the connection of two copper bars, can also be existed to two copper bars
It is pre-positioned before welding, consequently facilitating being welded around clamping gap.
Further, clamping structure is set as when the first copper bar 1 and the second copper bar 2 are by opposite pulling force, linkage section 3
It is able to maintain connection not separate, that is to say, that two copper bars are by the way that before welding, two copper bars pass through after clamping structure connection
Clamping structure progress is preliminary self-locking, in this way, when two opposite directions pull two copper bars respectively, it can't at linkage section 3
It is separated from each other, has certain tensile strength after welding can be further at linkage section 3 in this way, allowing for two copper bars
The tensile property of the weld seam at linkage section 3 is promoted, so that the copper bar after connection of being more convenient for is pulled according to specific requirements and is routed.
Further, clamping structure may include: card slot 4, and card slot 4 is formed in one in the first copper bar 1 and the second copper bar 2
One end on；Clamp 5, clamp 5 are formed in the first copper bar 1 and the second copper bar 2 on one end of another one；Wherein, clamp 5 is matched
It closes in card slot 4.In this way, can be welded by the clamping gap of clamp 5 and card slot 4.
The specific location and depth of card slot 4 can be set according to demand, for example, card slot 4 runs through one in a kind of form
Copper bar thickness and axially extending along copper bar since the end face of one end of one；The thickness of clamp 5 and the copper bar of another one
Thickness is identical and axially extended along copper bar since the end face of one end of another one.In this way, in connection, one of being more convenient for copper
Clamp on row is directly inserted into the card slot 4 on another one copper bar, meanwhile, clamping can be all formed on two sides of copper bar
Gap, to be welded at clamping gap on two side faces, to promote the reliability of linkage section 3.
As shown in Figure 2, in a kind of preferred embodiment, the notch size of card slot 4 is less than vallecular cavity bottom size；Before the head of clamp 5
Size is held to be greater than head tip dimensions；Wherein, notch size is identical as head end, and vallecular cavity bottom is identical as head front end size.In this way,
When connection, clamp 5 can be pressed into card slot 4 from the one side of card slot 4, so that being formed between clamp 5 and card slot 4 self-locking
Be clamped gap, meanwhile, between the end face of two copper bars formed splicing gap, in this way, along on two sides clamping gap and
Splicing gap is welded, and can be promoted the reliability of linkage section 3 more significantly, be promoted the tensile property of weld seam, meanwhile, connection
The thickness of the whole copper bar formed is uniform, that is to say, the consistency of thickness of thickness and copper bar at linkage section 3.
In addition, in the battery modules connection copper bar, the first copper bar 1 and the second copper bar 2 can be selected any appropriate
Hardness, for example, the first copper bar 1 can be hard copper bar, the second copper bar 2 can be soft copper bar, wherein soft copper bar includes the more of stacking
Layer copper strips, and the both ends for the multiple layer of copper band being laminated are respectively welded and link together.In this way, by the connection of soft or hard copper bar, more
Convenient for being routed according to practical structures.
Further, it is contemplated that tensile property, it is preferable that clamp 5 is formed in hard copper bar, and card slot 4 is formed in soft copper bar
On, structure as shown in Figure 2.
Certainly, as shown in Figure 1, the other end of two copper bars is respectively formed with connecting hole, in order to pass through bolt for copper
Row connect with battery modules.In addition, insulating layer can be set on copper bar, such as suit flexible insulated hose.
Finally, the utility model provides a kind of battery pack, including multiple battery modules, wherein at least two battery modules
Between connected by battery modules connection described in any of the above with copper bar.As described above, the globality of such battery pack
It can get a promotion with aesthetics.
The above is only the better embodiments of the utility model, are not intended to limit the utility model, all in this reality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the utility model
Within protection scope.
