[0019] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0020] The specific implementation process of the utility model is as follows:

[0021] like Figure 1 As shown in Figure 4, a battery module splicing fixing bracket includes an upper bracket 1, a lower bracket 2, a battery cell 3 and an electrode connecting piece 4. The upper bracket 1 and the lower bracket 2 are respectively located at the upper end and the lower end of the battery cell 3. The battery cell 3 is located between the upper bracket 1 and the lower bracket 2. A plurality of battery cells 3 are spliced ​​and assembled into a battery module through the upper bracket 1 and the lower bracket 2. The upper bracket 1 and the lower bracket 2 are used to fix and support the battery cell 3. The upper bracket 1 and the lower bracket 2 are both composed of the same splicing bracket 5, and the splicing bracket 5 has a splicing portion, and two adjacent splicing brackets 5 are connected by the splicing portion. Each splicing bracket 5 is provided with a plurality of battery cell placement slots 6. The battery cell placement slots 6 on the upper bracket 1 are arranged opposite to the battery cell placement slots 6 on the lower bracket 2. The two ends of the battery cell 3 are respectively provided with positive pole ears and negative pole ears. The battery cells 3 with opposite pole ears are placed in the two adjacent battery cell placement slots 6, and then the positive pole ears of the battery cells 3 and the negative pole ears of the adjacent battery cells 3 are connected through the electrode connecting sheet 4, so that the battery cells 3 in the battery module are connected in series, thereby increasing the voltage of the battery module. By splicing and connecting multiple splicing brackets 5, battery modules of different specifications and sizes can be assembled. A packaging tape placement slot 7 is provided on the side of the splicing bracket 5 away from the battery cell placement slot 6, and the packaging tape placement slot 7 is used to place the packaging tape 8. In this embodiment, a plurality of packaging tape placement grooves 7 are provided on the splicing bracket 5 for bundling the battery module. The packaging bag is a plastic-steel belt, which has good corrosion resistance, aging resistance, high temperature resistance and other properties, and can maintain a good fixing effect in various environments. The packaging tape 8 further makes the installed upper bracket 1 and the lower bracket 2 firmly attached to the battery cell 3, ensuring that the battery module will not loosen or shift during transportation and use.
