Description
[technical field]
The utility model relates to the battery pack interconnection technique, more particularly, relates to a kind of syndeton of battery pack pole piece.
[background technology]
In short supply along with oil, and people are to the raising of environmental requirement, electric automobile and hybrid vehicle more and more show its superiority.As the core drive the energy---power battery pack of electric automobile, it is particularly outstanding that its importance seems.At present, safety, volume are little because it has, the energy density advantages of higher forms the first-selected power source into people for ferric phosphate lithium cell, can form power battery pack through a plurality of cells of serial or parallel connection.
Because violent jolting may take place in automobile in driving process, so when the assembly mechanical structural design of battery pack, can the power battery pack of electric automobile and hybrid vehicle be designed to usually be in the same place by some little battery pack connection in series-parallel.Syndeton between existing two battery pack is such; Please refer to shown in Figure 1; First battery pack comprises and is fixed with somely perpendicular to first pole piece and the mutual cells of parallel connection on first pole piece, 90, the first pole pieces 90 that the upper end of first pole piece also is provided with first connecting portion 91 that roughly is the L type; Second battery pack comprises second pole piece 80 and second connecting portion 81, and its structure with first battery pack is consistent.When first and second battery combination is connected, can use bracket 82, double-screw bolt 83 and nut 84 that first and second pole piece is fixed together usually, yet; When being fixed together, the operator can carry out work on the left and right sides at first and second pole piece, therefore; The operating space is limited; Operative orientation is limited, so can only manual work accomplish, causes operating efficiency low.
In view of above drawback, the syndeton that is necessary a kind of battery pack pole piece is provided in fact is to overcome above-mentioned defective.
[utility model content]
The purpose of the utility model provides a kind of simple in structure, when the assembled battery group, and the syndeton of the battery pack pole piece that can increase work efficiency.
To achieve these goals; The utility model adopts following technical scheme: a kind of syndeton of battery pack pole piece, and it comprises the bolt and the nut of battery pack pole piece, two double-screw bolts, wherein; Said battery pack pole piece comprises substrate; Offer first through hole that at least one is used for fixing and electrically connects the cell electrode on the substrate, the end bending of substrate extends to form the connecting portion perpendicular to substrate, offers second through hole on the connecting portion; Second through hole of the bolt-through of two double-screw bolts on connecting portion, the end of the bolt of said pair of double-screw bolt also is combined with nut.
Preferably, also be equipped with connecting plate between said battery pack pole piece and the nut.
Preferably, the cell that electrically connects on the said substrate is perpendicular to the battery pack pole piece.
Preferably, the bolt of said pair of double-screw bolt comprises two double-screw bolts that are flat spiral shell head and upwards extend in parallel from an end face of spiral shell head.
Preferably, the bolt of said pair of double-screw bolt runs through second through hole on the connecting portion from the following orientation of battery pack pole piece.
Compared with prior art; The syndeton of the utility model battery pack pole piece simple in structure; Cost of manufacture is low, and adopts the bolt of the two double-screw bolts good stability that not only locks, and it runs through from the through hole in the following orientation of battery pack pole piece; Can make things convenient for the position work up of hand hydraulic cutting presser device, thereby improve staff's operating efficiency.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the syndeton of existing battery pack pole piece;
Fig. 2 is the three-dimensional exploded view of the syndeton of the utility model battery pack pole piece;
Fig. 3 is the three-dimensional combination figure of the syndeton of the utility model battery pack pole piece.
[embodiment]
Please refer to Fig. 2 to shown in Figure 3, the syndeton 100 of a kind of battery pack pole piece of the utility model, it comprises the bolt 20 and the nut 30 of battery pack pole piece 10, two double-screw bolts.
Battery pack pole piece 10 comprises substrate 11, offers first through hole 12 that at least one is used for fixing and electrically connects the cell electrode on the substrate, and the end bending of substrate 11 extends to form the connecting portion 13 perpendicular to substrate, and connecting portion 13 is provided with second through hole 14.
The bolt 20 of said pair of double-screw bolt comprises two double-screw bolts 22 that are flat spiral shell head 21 and upwards extend in parallel from an end face of spiral shell head 21.
When the assembling power battery pack; Earlier some batteries are electrically connected in first through hole 12 on the substrate 11 of battery pack pole piece; These cells just can be installed together any two the battery pack pole pieces 10 that are electrically connected with cell perpendicular to substrate 11 more relatively, and guarantee that the connecting portion 13 of two battery pack pole pieces 10 overlaps; The bolt 20 of the two double-screw bolts of usefulness is through to second through hole 14 from the following orientation of the connecting portion of battery pack pole piece again; Sheathed connecting plate 15 on the double-screw bolt that from second through hole 14, passes again, last, with hand beer 40 nut is screwed on the double-screw bolt.
Because the syndeton of the utility model battery pack pole piece, through the structural design to the battery pack pole piece, thereby the operation that will lock two adjacent cell group pole pieces has realized automation, effectively raises operating personnel's operating efficiency.
The syndeton of the utility model battery pack pole piece; Be not restricted to described in specification and the execution mode; Therefore for the personnel of familiar field, can easily realize additional advantage and modification; So under the situation of the spirit of the universal that does not deviate from claim and equivalency range and limited and scope, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
