[detailed description of the invention]
In order to make, the purpose of this utility model, technical scheme and useful technique effect are more clear to be understood, belowBy reference to the accompanying drawings and detailed description of the invention, the utility model is further elaborated. Should be understood that,The detailed description of the invention of describing in this description is only used to explain the utility model, is not in order to limitThe utility model.
As shown in Figure 1, battery pack series board 100 is for being associated in all battery strings of battery modules 200Together.
As shown in Figure 2 and Figure 3, battery pack series board 100 comprises cylinder manifold 1, is positioned at cylinder manifold 1 upper and lower twoThe first insulation board 21, second insulation board 22 of side, be positioned at the first insulation board 21 tops the first support 31,Be positioned at the second insulation board 22 belows the second support 32, be assembled in the many of the first support 31, the second support 32The fuse 5 of individual shell fragment 4 and connection shell fragment 4 and cylinder manifold 1.
Cylinder manifold 1 by metal material making case as copper. Shell fragment 4 comprises the bullet for the battery core of elasticity butt batteryProperty portion 41 and connect the installation portion 42 of elastic portion 41. The second support 32 comprises and can pass for elastic portion 41Installing hole 321, be positioned at installing hole 321 around and accommodate the mounting groove 322 of installation portion 42 and with installationThe connecting hole 323 that hole 321 is communicated with. The structure of the first support 31 is identical with the second support 32, and comprising can ammunition feedProperty portion 41 installing hole 311 that passes, be positioned at installing hole 311 around and accommodate the mounting groove 312 of installation portion 42And the connecting hole 313 being communicated with installing hole 311. Shell fragment 4 and the first support 31, the second support 32 can lead toCrossing welding realizes fixing.
The first insulation board 21 between the first support 31 and cylinder manifold 1, thereby make shell fragment 4 and cylinder manifold 1Isolation mutually. The first insulation board 21 is provided with multiple through holes 211, and through hole 211 is connected with the first support 31Hole 313 communicates. Fuse 5 one end connect the installation portion 42 of shell fragments 4, the other end through connecting hole 313,Through hole 211 links together shell fragment 4 and cylinder manifold 1. The second insulation board 22 is positioned at cylinder manifold 1 and secondBetween support 32, thereby make shell fragment 4 and cylinder manifold 1 mutually isolate. The second insulation board 22 is provided with multipleThrough hole 221, through hole 221 communicates with the connecting hole 323 of the second support 32. Fuse 5 one end connect shell fragment4 installation portion 42, the other end is connected to one through connecting hole 323, through hole 221 by shell fragment 4 and cylinder manifold 1Rise. In the time that battery core is short-circuited, fuse 5 fusing realize the protection to battery core.
The first support 31 and the second support 32 are fixed together by bolt or bayonet unit, thereby make firstSupport 31, the first insulation board 21, cylinder manifold 1, the second insulation board 22, the second support 32, shell fragment 4, guarantorDanger silk 5 is fixed together jointly. Adopt after the utility model battery pack series board 100, battery core no longer needsWeld on two sides, is contacted and conduct electricity with battery core both positive and negative polarity by shell fragment, and contact internal resistance is also smaller, fallsThe internal resistance that low screw connects, the unreliability of having avoided screw to connect, makes battery pack assembling simple, and tears openUnload easily.
Battery pack series board 100 is not only confined to cylindrical battery, and for example 18650,32650 etc., sameAlso be applicable to rectangular cell.
Be illustrated in figure 4 the shell fragment 6 of the utility model for battery pack series board, be in Fig. 1 to Fig. 3 simultaneouslyAnother embodiment of shell fragment 4, unitedly calls shell fragment 6 while being described below. Shell fragment 6 comprises for elasticity buttThe installation portion 62 of the elastic portion 61 of the battery core of battery and connection elastic portion 61. Shell fragment 6 is assembled in firstOn frame 31, the second support 32, installation portion 62 is contained in mounting groove 312,322, and elastic portion 61 is through peaceDress hole 311,321, other dependency structure is not described one by one.
Installation portion 62 ringwise, comprises interior ring limit and outer annular edge. Elastic portion 61 comprises from installation portion 62Multiple cantilevers 611 that interior ring limit tilts to extend, the quantity of cantilever 611 is 6 in the present embodiment, installation portionBe annular, but in other embodiments, cantilever 611 quantity are variable.
Cantilever 611 is ligulate, it comprise one end be connected and installed portion 62 interior ring limit connecting portion 6111 andThe abutting part 6112 extending from the other end bending of connecting portion 6111. One end of abutting part 6112 connectsPortion 6111, the other end is unsettled. In the time of the battery core of shell fragment 6 butt batteries, the abutting part 6112 of multiple cantilevers 611Common butt battery core, and drive connecting portion 6111 strains of multiple cantilevers 611, thus increase elastic forceAnd overcurrent capability. Shell fragment 6 internal resistances reduce, and have increased the reliability being connected with battery core simultaneously.
The utility model, for the shell fragment of battery pack series board, is not restricted to institute in description and embodimentDescribe, therefore for the personnel of familiar field, can easily realize additional advantage and amendment, therefore notDeviate from the situation of spirit and scope of the universal that claim and equivalency range limit, this practicality is newType is not limited to specific details, representational equipment and illustrates here and the examples shown of describing.
