In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

Please refer to FIGS. 1 to 3 . The multi-cell battery assembly 10 of the present invention includes at least two batteries 20 , at least one flexible connector 30 , at least two fasteners 40 , and a positioning component 50 . In this embodiment, the number of batteries 20 is three, the number of flexible connectors 30 is two, and the number of fasteners 40 is four. The numbers of the aforementioned three can be adjusted according to actual needs. It is not limited to this.

The three batteries 20 are arranged side by side. The two opposite ends of the adjacent two batteries 20 respectively have a concave spherical surface 21 and a convex spherical surface 22. By cooperation of the concave and convex spherical surfaces 21 and 22, the front and rear Two adjacent batteries 20 can abut against each other in a relatively rotatable manner. The two adjacent batteries 20 are respectively provided with a connection groove 23 and a buckle portion 24 adjacent to the connection groove 23 on the concave and convex spherical surfaces 21 and 22, wherein as shown in FIG. 3 , the connection groove 23 has an opening section 25 , a slanted section 26 connected to the opening section 25 and a barbed section 27 connected to the slanted section 26 . In addition, two batteries 20 adjacent to each other are respectively provided with two slots 28 arranged at intervals on the concave and convex spherical surfaces 21 and 22 (as shown in FIG. The first electrical contact 29 (as shown in FIG. 4 ).

As shown in FIGS. 2 and 3 , the flexible connecting member 30 has a web 31 , two opposite oblique extension arms 32 and two opposite hook portions 33 . The web 31 is arranged on the opening section 25 of the connecting groove 23 of the battery 20 , the obliquely extending arm 32 is arranged on the obliquely extending section 26 of the connecting groove 23 of the battery 20 , and the barb 33 is arranged on the barb section of the connecting groove 23 of the battery 20 27. In this way, the two adjacent batteries 20 are connected together by the flexible connecting piece 30 .

The buckle 40 is engaged with the buckle portion 24 of the battery 20 and is pressed against the web 31 and the slanted arm 32 of the flexible connector 30, so as to position the flexible connector 30 between two adjacent batteries. 20 in the connecting groove 23. In addition, as shown in FIG. 4 , the fastener 40 has two second electrical contacts 42 arranged at intervals. The first electrical contact 29 of the buckle part 24 of the battery 20 will be respectively embedded and contacted, and then connected between the two fasteners 40 by a flat cable 44, so that the two adjacent batteries 20 pass through the two The configuration between each fastener 40 and the flat cable 44 forms a series relationship.
