AI Technical Summary
Existing energy storage devices are prone to battery module loosening and lack stability during movement, making them unsuitable for mobile energy storage scenarios.
A mating part is set on the battery module, and a pressing part is set on the frame. The movement of the battery module along the height direction of the frame is restricted by the cooperation between the pressing part and the mating part. Combined with the design of the elastic inclined wall and the limit block, the risk of movement of the battery module is reduced.
This effectively reduces the risk of battery modules becoming loose during movement, improves the stability of battery modules, and makes them suitable for mobile energy storage scenarios.
