[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and Advantageous Effects become apparent from understanding, below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.It should be appreciated that the detailed description of the invention described in this specification is only used to explain this utility model, it is not intended to limit this utility model.
As it is shown in figure 1, the battery modules 100 of this utility model electric automobile include multiple battery core 10, house the support 21 of battery core 10,22, be assembled in the cylinder manifold 3 of support 21,22, dividing plate 4, fixed block 5 and sampling unit 6.
As shown in Figures 2 to 4, cylinder manifold 3 includes metallic plate 31 and is assembled in the nickel sheet 32 of metallic plate 31.Metallic plate 31 is made such as copper coin, aluminium sheet etc. by metallic plate, and it includes flat part 311, the connecting portion 312 extended from the edge-perpendicular of flat part 311 and the multiple through holes 313 being positioned on flat part 311, and connecting portion 312 is provided with installing hole 3121.Through hole 313 is corresponding with the electrode of battery core 10.
Nickel sheet 32 is stamped and formed out by the soft nickel strap that thickness is 0.1mm～0.2mm, multiple circular holes 322 of including substrate 321, being positioned on substrate 321 and the elastic 323 extended from the edge of circular hole 322, circular hole 322 overlap with the through hole 313 of metallic plate 31 and with battery core 10 one_to_one corresponding.
As it is shown in figure 5, elastic 323 includes a pair elastic arm 3232 at the edge of contact site 3231 at its center and connection contact site 3231 and circular hole 322.Contact site 3231 is abutted with the electrode of battery core 10 and is fixed together by spot welding, and contact site 3231 is provided with through hole 3233, and through hole 3233 is in elongated, and such design increases spot welding area, makes nickel sheet 32 more firm with the solder joint of battery core 10, and conveyance capacity is more preferable.Elastic arm 3232 is curved, and two elastic arms 3232 are symmetrical and are collectively forming S-shaped, and such design makes elastic 323 all can move in X, Y, Z axis direction, it is therefore prevented that the vibration of all directions causes the fracture of nickel sheet 32.Elastic arm 3232 is provided with fusible portion 3234; the width in fusible portion 3234 is less than the width of elastic arm 3232; when big electric current is through out-of-date; fusible portion 3234 fuses; thus cut off the loop of single battery core 10; fusible portion 3234 is equivalent to electric fuse, and such design can be protected single-unit battery core 10 thus protect whole circuit.
The cylinder manifold 3 of the battery modules of this utility model electric automobile uses soft nickel sheet to be stamped and formed out elastic, is possible to prevent during vibration to rupture, and includes that fusible portion protects whole circuit.
