They are mainly different from starting batteries used to start car engines. They mostly use valve-sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries; the battery packs of new energy vehicles are usually installed at the bottom of the car.

[0003] When performing maintenance or replacement of new energy batteries, the car is generally lifted by a lift, and then the new energy battery is lifted, removed and moved by a support frame for replacement. However, for the convenience of movement, the existing new energy battery support frame generally has universal wheels at the bottom. Although the universal wheels have a self-locking mechanism, the use process requires locking four universal wheels in turn, which is cumbersome, and the contact area between the universal wheels and the ground is small, which leads to reduced overall stability, and the support frame is prone to displacement when lifting new energy. Improvements are provided in this regard. Utility Model Content
