Description

Technical Field

[0001] The utility model belongs to the technical field of anti-theft locks, and in particular relates to a battery lock core mechanism. Background Art

[0002] Usually, a battery box needs to be installed on an electric bicycle to realize power supply. At present, most electric bicycles install lithium batteries in the lower tube of the frame to realize space utilization and make the vehicle body small and lightweight. Generally, the battery box needs to be fixed in the installation slot by a lock on the lower tube.

[0003] At present, in order to increase the unlocking process and avoid the battery box from falling out of the hand due to instant unlocking, the lock core structure used for the lithium battery box of electric bicycles is usually designed with double lock tongues. When unlocking, the two lock tongues are unlocked one by one to remove the lithium battery box.

[0004] It was retrieved that in the prior art, a Chinese utility model patent with authorization announcement number CN216690689U discloses a "double lock tongue structure on an electric bicycle lithium battery box". The battery box is installed in a mounting groove of the downtube of the electric bicycle, one end of the mounting groove is provided with the double lock tongue structure, and the other end has a plug structure that can be electrically connected to the lithium battery. The double lock tongue structure includes a lock shell, a lock core and double lock tongues. The double lock tongues are two separate lock tongues. A lock core cavity and a double lock tongue slide are formed in the lock shell. The lock core cavity is connected to the double lock tongue slide and forms an "L"-shaped cavity as a whole.
