Automatic locking and unlocking device, electric changing robot, electric charging and changing power station and locking and unlocking method

Abstract

The invention relates to the field of electricity change, in particular to an automatic locking and unlocking device, an electric changing robot, an electric charging and changing power station and a locking and unlocking method. The invention aims to solve the problems that stability of a semi-automatic or manual fastening manner existing in the fastening process of an energy storing unit is poor and the like. The automatic locking and unlocking device comprises a shell, a tool part and a drive part. The shell is provided with a first bottom plate and a second bottom plate. The first end of the tool part extends out of the first bottom plate and can be in fitting connection with a fastening part to be operated. The tool part can move in the axial direction relative to the drive part. The drive part is contained in the shell. The drive part is connected with the second end of the tool part. The drive part enables the tool part to rotate. Rotating can drive the fastening part to be fastened to or separated from a vehicle needing electric changing. By arranging the tool part and the drive part, the action enabling the fastening part to be fastened to or separated from the vehicle needing electric changing can be completed automatically, the energy storing unit can be locked or unlocked automatically, and precision and stability of the locking and unlocking process can be improved.

Description

technical field [0001] The invention relates to the field of battery swapping, in particular to an automatic unlocking device, a battery swapping robot, a charging and swapping station, and an unlocking and unlocking method. Background technique [0002] As an emerging means of transportation, new energy vehicles are favored by major manufacturers and car owners due to their advantages of energy saving, environmental protection and low working noise. In the process of replacing the energy storage unit for new energy vehicles, the fastening and disassembly of the energy storage unit is an essential step. Taking electric vehicles as an example, using bolts as the fasteners between the power battery and the electric vehicle body is a connection method commonly used by major manufacturers. In the fastening process, using a tightening gun through semi-automatic or manual, or using a customized non-standard automatic fastening device, integrating the tightening gun into the autom...
