Lithium battery pack packaging box

Abstract

The invention discloses a lithium battery pack packaging box. A special packaging container which can be sealed is designed according to the boundary dimension and the structural style of a lithium battery pack, the packaging box is of the structure of a double-layer box body with flanges, a metal bearing frame is pre-buried in an interlayer, so that it is guaranteed that the packaging box can be lifted and stacked, and the box body is made of glass fiber reinforced plastic with the extremely low density; the interior of the packaging box is made to be in the low vacuum state by vacuumizing the packaging box firstly and then filling the packaging box with dry air or nitrogen, and the interior of the packaging box is in the positive pressure state all the time, so that a stable storage environment is provided for the lithium battery pack contained in the packaging box; a sealing structure is designed specially, a sealing piece is of an inflatable double-peak structure and is made of butyl rubber, in this way, the airtightness is high, and the requirement for a large sealing structure of the packaging box is well met; the state of lithium batteries packaged in the packaging box and the environment of the interior of the packaging box can be detected. According to the lithium battery pack packaging box, the air pressure, the temperature and the humidity of the interior of the packaging box where the lithium batteries are packaged and the liquid leakage condition of the lithium batteries can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of lithium battery protection, in particular to a packaging box for lithium battery packs. Background technique [0002] At present, the packaging technology of lithium batteries is relatively simple, and the adaptability to the external environment is not strong. The packaging technology is not standardized, the safety is not strong during long-distance transportation, the long-term storage and use requirements of users cannot be met, and the environmental adaptability is poor. Contents of the invention [0003] In view of this, the present invention provides a packaging box for a lithium battery pack, which has sufficient strength and rigidity, and is convenient for rapid packaging, long-term storage, and long-distance transportation of the lithium battery pack. [0004] A packing box for a lithium battery pack, comprising an upper box body, a lower box body, a locking device and a sealing ring; [000...
