Description

Battery pack shell Technical Field The utility model relates to the technical field of battery packs, in particular to a battery pack shell. Background To improve the convenience of stacking and handling the battery packs, conventional battery pack cases are generally provided with a carrying handle and an independent positioning device. However, such a design increases the production cost of the battery pack case on the one hand, and decreases the work efficiency of stacking and handling the battery packs in actual operation on the other hand. In view of this, the prior art proposes an improved battery pack structure, wherein the top two sides of the improved battery pack structure are provided with lifting handles, and the bottom two sides of the improved battery pack structure are provided with positioning grooves corresponding to the handles. When the battery packs are stacked, the handle of the upper battery pack can be directly inserted into the positioning groove of the lower battery pack, so that the handle can be used for carrying and can serve as a guide piece to assist the battery packs to be stacked accurately and stably. Although this design simplifies the structure by the cooperation of the positioning groove and the handle, which improves the stacking efficiency, the positioning groove inevitably occupies the internal space of the battery pack, reducing the area available for accommodating the battery cells or other components. Also, to accommodate such designs involving special structures, the production of battery pack cases requires special die-opening fabrication, which not only increases the cost of initial die development, but may also limit the flexibility of production and the speed of response to market changes.
