Description

Technical Field

[0001] The utility model relates to the field of PACK lower box transportation, in particular to an adjustable pallet base. Background Art

[0002] With the growing global demand for clean energy, lithium batteries have been widely used as an efficient and environmentally friendly energy storage method, especially in new energy vehicles. The lithium PACK battery pack mainly includes an upper cover, a lower box, a sealing structure, a pressure strip, a bracket, etc. The lower box of the battery box is the bearing of the entire power battery system product, and the battery module is mainly arranged inside the lower box. Therefore, there must be structural measures such as embedded grooves and baffles inside the battery box to ensure that the battery module is reliably fixed when the vehicle is driving, and there is no movement in the front, back, left, right, up and down directions to avoid impact on the side walls and the upper cover, which affects the life of the battery box. Due to the structure of the lower box of the PACK itself, in order to facilitate its transportation, it is necessary to use a lower box pallet box and place it on the pallet box for stacking and transportation. The current pallet box is not convenient to adjust according to the size of the transport vehicle and the size of the battery pack, and is not convenient to use.
