Description

Technical Field

[0001] This utility model relates to the field of intelligent battery swapping cabinet technology, specifically to a battery compartment structure and intelligent battery swapping cabinet that is compatible with both hard and soft plugs. Background Technology

[0002] Smart battery swapping cabinets greatly facilitate battery swapping for electric bicycles. These cabinets have multiple battery compartments that can hold batteries, which can then be connected to chargers for charging. When a customer's electric bicycle runs out of power, they can interact with the cabinet to replace the depleted battery with a fully charged one – a simple, efficient, and convenient process that greatly improves convenience. Currently, there are many types of removable batteries on the market compatible with smart battery swapping cabinets, varying in size and specifications. The connection between the battery and the charging socket in the battery compartment typically involves either a hard-plug or a soft-plug method. A hard-plug method involves the battery being pushed into the compartment and its charging port directly engaging with the hard-connector. A soft-plug method involves the user manually connecting the battery to the charging port using a soft-connector. Currently, most smart battery swapping cabinets only support a single battery type or model, limiting their applicability and preventing compatibility with a wider range of battery types.
