Description

Technical Field

[0001] The utility model relates to the field of battery replacement, in particular to an automatic power battery replacement device. Background Art

[0002] Power batteries are the power source for tools, mostly referring to batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are the core components of new energy vehicles and an important direction for future energy transformation.

[0003] In the prior art, in addition to directly charging, power batteries can also be replaced. After replacing the power battery, the replaced power battery that is out of power needs to be placed in a charging bin for charging, and then taken out for storage after charging is completed. However, most of the existing power battery replacement devices use manipulators to take out and replace the batteries. The cost of using manipulators to take out and replace batteries is high, and the power battery is heavy. When using manipulators or other clamping equipment to load and unload the power battery, it is easy for the single point of the power battery to be subjected to excessive force and cause deformation, thereby causing safety hazards.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
