Technical Field

[0001] The utility model relates to the technical field of new energy vehicle maintenance, and more specifically to a battery pack positioning device. Background Art

[0002] The battery pack is a large-capacity battery group composed of multiple batteries. It is the main power source for new energy vehicles on the market. When disassembling and repairing the battery pack of a new energy vehicle, a battery pack positioning device is required.

[0003] At present, most of the battery pack positioning devices used for repairing new energy vehicles are frame-type structures. The method adopted is to position the battery pack on the surface of the frame, then move the frame to send the battery pack to the bottom of the new energy vehicle, and then drive the battery pack to rise and send the battery pack into the battery compartment at the bottom of the vehicle, so as to complete the purpose of battery pack repair and installation. However, the current battery pack positioning device lacks the effect of fine-tuning the position of the battery pack. When pairing and adjusting the position of the battery pack and the battery compartment, the entire frame structure needs to be moved. The overall frame structure is relatively large, which undoubtedly has the defect of poor adjustment accuracy. It is difficult to quickly and accurately adjust the position of the battery pack, resulting in low installation efficiency of the battery pack.

[0004] In view of this, the utility model proposes a battery pack positioning device which can accurately adjust the position of the battery pack. Utility Model Content
