The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The invention will be further explained with reference to the drawings in the following description:
as shown in fig. 1 and fig. 2, a soft packet of lithium cell external structure, including a plurality of electric cores, be provided with aluminum sheet 1 between the electric core and connect the utmost point ear of electric core, according to actual required group battery design series-parallel structure, seted up overflow groove 101 on aluminum sheet 1 in order to reduce the flow area, the outside of aluminum sheet 1 is provided with cardboard 2, has seted up a plurality of draw-in grooves 201 that supply aluminum sheet 1 to place according to actual aluminum sheet 1 quantity on cardboard 2.
In this embodiment, the below of electric core is provided with bottom plate 3, conveniently installs electric core, and wire hole 301 has been seted up to side of bottom plate 3 to in with the whole and outside intercommunication of group battery, through glue bonding one-tenth a whole between cardboard 2, aluminum plate and the bottom plate 3, follow-up with whole and external member welded fastening can.
The utility model discloses the theory of operation as follows:
firstly, designing a cell placing position according to the required cell number and the number of series-parallel connection plus the cell size and the shell size, determining the cell lug position according to the cell placing position, designing a bottom plate 3 according to the lug position and the wire outlet requirement, designing an overcurrent aluminum sheet 1 according to the overcurrent size and the cell lug width and the anode and cathode positions, finally designing a clamping groove 201 plate according to the size of the aluminum sheet 1 and the size of the bottom plate 3, processing three parts by a carving machine, bonding the three parts into a whole by glue, and welding the three parts with an external part.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
